Definitions
- THE PRESENT INVENTION relates to a drawer, such as is provided in an item of household furniture, and more particularly to a connection for mounting a fascia panel on part of a drawer body.
- a drawer body As an integrally moulded, single unit and to provide a separate fascia panel, together with means for connecting the panel to the drawer body. It is also known to form a drawer body in kit form comprising a base and upstanding walls which are interconnectable to form the drawer body. Again it is necessary to provide means for connecting a fascia panel to part of the drawer body. References in this document to a drawer body are to be understood to cover either an integrally formed body or a body in kit form.
- the present invention seeks to provide a drawer having a connection between a drawer body and a fascia panel which is simple and cost-efficient to produce and assemble and which enables adjustment of the fascia panel relative to the drawer body, both vertically and horizontally, in a quick and simple manner.
- a kit of parts for forming a drawer comprising a drawer body and a fascia panel adapted to be mounted on the front of the drawer body, the fascia panel and the drawer body having means for releasably retaining the panel adjacent the front of the drawer body, part of the retaining means being movable between a first position in which the retaining means permit movement of the fascia panel relative to the drawer body and a second position in which said part of the retaining means locks the fascia panel in position relative to the drawer body; the kit further comprising means mountable on the drawer for moving said part of the retaining means to the second position.
- the releasable retaining means comprise a projection extending rearwardly of the fascia panel and a channel formed at the front of the drawer body, the channel defining an opening through which the projection may be introduced into the channel.
- the channel extends substantially vertically and is formed at the front of a side wall of the drawer body, the channel having an opening extending into the front of the channel, through which part of the projection protrudes when the projection is inserted into the channel.
- the projection is in the form of a connector element comprising a front portion and a rear portion, the front portion being received wholly within the channel and the rear portion protruding through said opening and being connected to the rear surface of the fascia panel.
- the front portion of the connector ele- ment comprises a central region of reduced thickness, there being an aperture between said central region and the rear portion of the connector element, the central region constituting said part of the retaining means movable between said first and second positions.
- the central region of the front portion of the connector element is connected to the remainder of the front portion by relatively thin, flexible webs of material.
- the means for moving the central region of the front portion of the connector element between the first and second positions comprise a member introducible into the aperture between the central region of the front portion and the rear portion of the connector element, the thickness of the member being greater than the depth of the aperture between the central region and the rear portion of the connector element such that, upon insertion of the member into the aperture, said thin webs of material flex and the central region of the front portion of the connector element is moved away from the rear portion so as to project beyond the remainder of the front portion of the connector element and moves forcibly into engagement with a wall of the channel formed at the front of the drawer body when the connector element is received within that channel, thereby locking the fascia panel in position relative to the drawer body.
- the means for moving the central region of the front portion of the connector element between the first and second positions comprise a cover plate receivable within a shallow recess formed in a side wall of the drawer body, the cover plate carrying said member which is introducible into the aperture between the central region of the front portion of the connector element and the rear portion of the connector element, the shallow recess in the side wall having an aperture through which the member passes when it is to be introduced into the aperture in the connector element.
- the shallow recess defines a further aperture and the cover plate carries a projection designed to be received in that further aperture as a snug fit so as to retain the cover plate in position within the shallow recess.
- the central region of the front portion of the connector element and said wall of the channel define cooperating sets of teeth which are brought into engagement when the central region is forced into engagement with the wall, the sets of teeth serving to prevent movement of the fascia panel relative to the drawer body in one or more directions.
- the sets of teeth may serve to prevent vertical and horizontal movement of the fascia panel relative to the drawer body.
- this invention provides a method of forming a drawer from a kit of parts as described above the method comprising the steps of connecting a projection to the rear surface of the fascia panel and inserting said projection into a channel formed at the front of the drawer body such that the panel is retained adjacent the front of the drawer body; mounting a member upon the drawer body so as to engage part of the projection and move said part of the projection from a first position in which the fascia panel may move relative to the drawer body to a second position in which the part of the projection locks the fascia panel in position relative to the drawer body.
- This invention further provides a drawer when formed from a kit of parts as described above, and an item of furniture incorporating such a drawer.
- the drawer body comprises an integrally moulded unit which is, in plan view, substantially square and comprises a base 5, side walls 6 and a rear wall 7.
- Each of the side walls 6 are of similar form and extend outwardly at their upper edge in an arcuate manner and then extend downwardly as a depending skirt 8 which turns inwardly before again extending downwardly to the level of the base 5.
- the skirt 8 has an upper portion extending over approximately two thirds the depth of the side wall and a lower portion which extends over approximately one third the height of the side wall.
- the region between each of the side walls 6 and their respective skirts 8 is hollow.
- each side wall 6 is connected to its associated skirt 8 by way of a vertical front wall 9, each front wall 9 defining a rectangular opening 10 which extends upwardly from the base of the drawer (where it has an open mouth) over approximately three quarters of the height of the side wall.
- a further vertical wall 11 extends between the side wall 6 and the skirt 8 at a position just behind the front wall 9.
- the wall 11 carries a set of vertically extending, parallel serrations or teeth 12 which are of a limited depth and are positioned just beneath the level of the upper edge of the opening 10.
- a horizontal set of teeth may be superimposed on the vertical teeth 12.
- the teeth 12 are designed to cooperate with a corresponding set of teeth formed on part of each connector element 3.
- each side wall of the drawer body defines a vertically extending, open bottomed channel which is of substantially T-shaped configuration when seen in horizontal cross-section, the head of the T being enclosed by the side wall 6, the wall 11 and the skirt 8, whilst the stem of the T is defined between the edges of the opening 10.
- This channel is designed to receive a connector element 3 which may be introduced into the channel via the open bottom thereof.
- each skirt 8 At the front end of each skirt 8 at a position just above the point where it turns inwardly, the upper portion of the skirt defines a shallow, generally rectangular recess 13.
- the recess defines two apertures, there being a first, rectangular upright aperture 14 positioned adjacent the front edge of the drawer and a second, elongated oval-shaped aperture 15 positioned behind the aperture 14 at a small distance therefrom.
- the aperture 14 extends through the skirt 8 into the hollow region between the side wall and the skirt at a position in front of the wall 11 i.e. it extends into the T-shaped channel at the front of the side wall.
- the aperture 15 extends through the skirt into the hollow between the skirt and the side wall at a position behind the wall 11.
- the shallow recess 13 is aligned vertically with the set of teeth 12 formed on the wall 11.
- the hollow region between the skirt 8 and the side wall 6 is accessible in the region of the recess 13 by way of an opening in the skirt 8 where the skirt turns inwardly. This opening is not visible in the drawings but allows a person's finger to enter behind the upper portion of the skirt 9 in the region of the recess 13.
- Each recess 13 is designed to receive a locking member 4.
- Each locking member 4 comprises a planar, substantially rectangular cover plate 16 of the same overall dimensions as the recess 13.
- the cover plate carries, adjacent one edge, a projection 17 which is of rectangular cross-section and which is dimensioned to pass through the aperture 14.
- the projection 17 defines a bevelled free edge 18.
- the cover plate 16 also carries an elongate oval-shaped projection 19 dimensioned to fit in the aperture 15. The free edge of the projection 19 is also bevelled at 20.
- Each connector element 3 comprises an integrally moulded elongate component having a relatively wide front portion 21 designed to be received wholly within the T-shaped channel formed at the front edge of each side wall of the drawer body and a relatively narrow rear portion 22 designed to pass through the opening 10 in the front wall 9.
- the rear portion 22 is located substantially centrally upon the rear of the front portion 21 and extends over only part of the width and only part of the height of the front portion, as is most clearly visible in Figures 5 and 6 of the drawings.
- the rear portion 22 defines a flat rear surface 23 which lies flat on the rear surface of the fascia panel 2 when the connector element is mounted thereon.
- Each connector element defines a pair of vertically spaced apart, countersunk screw holes 24 through which screws may be passed in order to screw the connector element onto the rear surface of the fascia panel.
- the holes 24 are countersunk so that the heads of the screws received within the holes lie substantially flush with or slightly below the front surface of the connector element.
- each connector element comprises three regions, there being an upper region 25, a central region 26 and a lower region 27.
- the upper region 25 and the lower region 27 are of equal thickness and are interconnected at the rear by the rear portion 22, whilst the central portion 26 is of lesser thickness such that an aperture 28 is defined between the rear portion 22 and the central portion 26.
- the depth of the aperture 28 in a direction extending perpendicularly between the rear portion 22 and the back of the central portion 26 is slightly less than the thickness of the projection 17 on the locking member 4.
- the height of the aperture 28 is slightly greater than the height of the projection 17.
- the upper region 25 and the lower region 27 are each connected to the central region by a relatively thin web of material 29 forming one side of the base of respective V-shaped grooves 30 which extend transversely across the front surface of the front portion 21 at the upper and lower borders of the central portion 26.
- the front surface of the central portion 26 carries a set of vertical, parallel teeth 31 designed to engage with the teeth 12 formed on the wall 11 in the drawer body. A set of horizontal teeth may be superimposed on the horizontal teeth 31.
- the connector elements 3 will be formed from polypropylene and the webs 29 will be sufficiently thin to enable them to flex slightly so that the central portion 26 may be urged away from the rear portion 21 thereby causing the surface carrying the teeth 31 to project beyond the plane of the front surface of the connector.
- the screw holes 24 are located in the upper and lower regions of the front portion at positions immediately adjacent the V-shaped grooves 30.
- the lower portion 27 has one side face which defines an inturned step 32 in similar manner to that which is defined by the skirt 8 on the drawer body.
- the lowermost section of the lower portion 27 is of lesser width than the remainder of the front portion of the connector element.
- the two connector elements 3 are screwed onto the rear of a fascia panel 2 at predetermined positions spaced across the width of the panel, the spacing corresponding to the distance between the T-shaped channels defined at the front of the side walls of the drawer body.
- the panel is then mounted on the front of the drawer body by introducing the connector elements 3 into the T-shaped channels at the front of the side walls of the drawer body.
- the connector elements are introduced into these channels by way of its open bottom, with the front portion 21 of each connector element being received between the walls 9, 11 and with the rear portion 22 of each connector element projecting through the opening 10.
- the teeth 31 on each connector element are aligned with, but spaced slightly from the teeth 12 formed on the wall 11.
- the two locking members 4 are now each inserted into a respective recess 13 on either side of the drawer body such that the projection 17 passes through the aperture 14 and the projection 19 extends into the aperture 15.
- the projection 17 passes into the aperture 28 and because that projection is of greater thickness than the depth of the aperture, that projection urges the central portion 26 away from the rear portion 22 and causes the teeth 31 to move into engagement with the corresponding teeth 12.
- the bevelled edge 18 at the free end of the projection 17 facilitates the insertion of the projection into the aperture 28 behind the central portion 26.
- the cover plate 16 When the locking member 4 is fully inserted the cover plate 16 is received with in the shallow recess 13 and lies substantially flush with the surface of the skirt 8, whilst the projection 19 is a tight fit within the aperture 15.
- the bevelled edge 20 on the projection 19 facilitates the introduction of that projection into the aperture 15.
- the locking members 4 can be released by pushing them out of their respective recesses 13. This is effected by passing a finger behind the skirt 8 at a position adjacent the recess 13 and pushing on the free end of the projection 19 so as to force the locking member 4 out of the recess 13. As the locking member 4 moves out of the recess 13 so the projection 17 is withdrawn from the aperture 28 and the sets of teeth 31, 12 become disengaged, thereby allowing movement of the fascia panel both vertically and horizontally.
- the connector elements and the channels within which they are received will be provided with cooperating means to enable the fascia panel to be supported upon the front of the drawer body before the locking members 4 have been placed in position.
- the connector elements and the channels may be provided with cooperating projections and recesses which form a flexible snap-fitting connection which supports the connector elements within the channels and thereby supports the fascia panel upon the front of the drawer body.
- the step 32 on the front portion of each connector element already serves this purpose to a certain degree, in that the step enables the connector to rest upon the corresponding step formed in the skirt 8. However there is no positive retention of the fascia panel in position relative to the drawer body with this arrangement.
- the locking members 4 may well be provided with means for retaining the locking members in position relative to the recess before the locking members have been fully inserted. It will still be possible to adjust the position of the fascia panel both vertically and horizontally relative to the drawer body when the panel is supported upon the front of the drawer body in this way and when the locking members 4 are supported in position relative to the recesses 13.
- Figures 7 to 10 illustrate modified components for enabling a fascia panel to be mounted upon the front of a drawer body.
- Figure 7 illustrates the front end only of one side wall 33 of a drawer body supplied in kit form.
- the complete drawer body would comprise a base, a pair of side walls, a front wall and a rear wall. I some cases the front wall may be omitted and a fascia panel can be mounted directly on the front ends of the side walls 33. Alternatively the rear of a fascia panel may carry the front wall of the drawer body which is in turn mounted on the front end of the side walls 33.
- each side wall 33 is designed to receive a connector element 34 mounted on the rear of a fascia panel, with each connector element 34 being positively retained in position relative to the front end of the its associated side wall 33 by means of a locking member 35.
- each side wall 33 has been modified to take account of the fact that the drawer body is to be provided in kit form and, as can be seen from Figure 7, the front end of each side wall defines a vertically extending channel 36 between inner and outer walls 37, 38 of the side wall.
- the channel has a base which is constituted by a vertical wall 39 extending between the inner and outer walls 37, 38, the vertical wall 39 being spaced rearwardly of a further vertical wall 40 which is positioned adjacent the front end of the side wall and which defines an opening 41 extending into the channel 36 from the front end of the side wall.
- the opening 41 has a first portion 42 which extends across approximately half of the width of the side wall and which is of greater height than a second portion 43 of the opening which extends across the other half of the width of the front wall.
- the second portion of the opening 41 is formed with a projecting rim 44 around three of its sides. It will be appreciated that the lowermost portion of the vertical wall 40 forms a web extending between the inner and outer walls 37, 38 adjacent the lowermost edge of the side wall 33 and this web prevents the insertion of a connector element 34 into the channel 36 via the open end of the channel 36 adjacent the base of the side wall when the connector element is mounted on the rear of the fascia panel.
- the front end of the side wall 33 defines a shallow recess 45 which is designed to receive the locking member 35.
- the recess 45 is generally L-shaped, having a portion which extends vertically at the front end of the side wall and a portion which extends horizontally from the front end towards the rear of the side wall adjacent the upper edge thereof.
- the outer wall 38 defines a rectangular upright aperture 46 which extends into the channel 36 in similar manner to the aperture 14 of the previous embodiment.
- the aperture 46 is aligned with a set of teeth 47 formed on the vertical wall 39 constituting the base of the channel 36.
- Each locking member 35 comprises a generally L-shaped portion designed to be received within the recessed area 45 formed on the outwardly directed face of the side wall 33 and a portion 48 which extends perpendicularly thereto, the portion 48 being designed to extend across the front end of the side wall 33 when the locking member is in place.
- the portion 48 defines a cut away region 49 which is designed to be aligned with the opening 41 when the locking member is in place.
- the locking member 35 effectively forms a cover plate and carries a projection 50 which is of rectangular cross-section and which is dimensioned to pass through the aperture 46.
- the projection 50 has a bevelled edge 51 which facilitates the mounting of a fascia panel on the front end of the drawer body.
- the connector elements 34 are of very similar design to the connector elements 3 which have been described above and thus comprise a front portion 52 which is dimensioned to pass through the first portion 42 of the opening 41 with a small clearance and a rear portion 53 which is of lesser height than the front portion and which is dimensioned so that it will just pass through the second portion 43 of the opening 41 with a small clearance.
- the front portion and the rear portion of each connector 34 are of the same width and each portion is of generally rectangular shape.
- Each connector element defines a pair of screw holes 54 by way of which the element is designed to be mounted upon the rear of a fascia panel or upon the rear of the front wall of a drawer body which is itself mounted on the rear of a fascia panel.
- each connector element is of the same design as the front portion of the connector element 3 described above and will therefore not be described in detail again other than to say that it comprises a central region 55 which is spaced from the rear of the connector by an aperture 56, the central region being connected to the remainder of the connector element by thin webs of material 57 which can flex slightly so as to permit the central portion 55 to be urged away from the rear portion 53 of the connector element.
- the front surface of the central region 55 again carries a set of teeth 58 designed to cooperate with the teeth 47 formed on the base of the channel 36.
- two connector elements 34 are mounted on the rear of a fascia panel or on the rear of a front wall of a drawer body which is itself mounted on the rear of a fascia panel so that the spacing between the connector elements corresponds to the spacing between the side walls 33 of the drawer body to which the fascia panel is to be connected.
- the panel (and the front wall of the drawer body if this is mounted on the rear of the panel) is then mounted on the front of each side wall 33 by introducing the connector elements 34 into the channel 36 through the opening 41.
- the connector elements are introduced into the channel not via the opening adjacent the base of the side wall but via the opening formed at the front of the side wall i.e. by pushing the connector elements into the channel in a direction towards the rear of the drawer body.
- the connector elements are inserted into the channel by passing the elements through the first portion 42 of the opening whereupon the fascia panel and the connector elements can be moved laterally such that the front portion 52 of each connector element is received behind the vertical wall 40 with the rear portion 53 of each connector element projecting out through the second portion 43 of the opening 41.
- the rear portion 53 of each connector element now rests upon the projection 44 formed around the periphery of the second portion 43 of the opening 41 and when the fascia panel is correctly positioned relative to the drawer body the locking members 35 can be located in position on each side wall 33.
- Each locking member is offered up to the side wall by introducing the projection 50 into the aperture 46. As the projection 50 passes through the aperture 46 it is automatically directed into the aperture 56 between the front and rear portions of the connector element 34.
- the projection 50 has a thickness which is slightly greater than the distance between the front and rear portions of the connector element 34 and thus the projection 50 urges the central portion 55 away from the rear portion 53 and causes the teeth 58 to move into engagement with the corresponding teeth 47.
- the bevelled edge 51 on the projection 50 facilitates the insertion of the projection into the aperture 56 defined by the connector element.
- the fascia panel is now effectively locked in place on the front of the drawer body and the locking member 35 is received within the recessed area 45 with its front portion 48 extending across the front of the side wall 33.
- the rearwardly extending portion of the L-shaped locking member may carry a further projection designed to be received within a further aperture formed in the outer wall 38 in similar manner to the projection 19 which is received in the aperture 15 in the embodiment described previously. This would serve to ensure that the locking member is retained securely in position within the recessed area 45.
- the teeth 47, 58 prevent sideways movement of the fascia panel relative to the drawer body and the frictional engagement between the front surface of the central portion 55 of the connector element and the wall 39 defining the base of the channel prevent vertical movement of the panel relative to the drawer body.
- horizontal sets of teeth could be superimposed upon the vertical teeth 47, 58 so that the two sets of teeth would prevent both horizontal and vertical movement of the fascia panel relative to the drawer body.
- Adjusting the position of the fascia panel relative to the drawer body can be effected in the same manner as described above by simply removing the locking members 35 adjusting the position of the panel as necessary and then replacing the locking members.

Abstract
Description
- THE PRESENT INVENTION relates to a drawer, such as is provided in an item of household furniture, and more particularly to a connection for mounting a fascia panel on part of a drawer body.
- It is known to form a drawer body as an integrally moulded, single unit and to provide a separate fascia panel, together with means for connecting the panel to the drawer body. It is also known to form a drawer body in kit form comprising a base and upstanding walls which are interconnectable to form the drawer body. Again it is necessary to provide means for connecting a fascia panel to part of the drawer body. References in this document to a drawer body are to be understood to cover either an integrally formed body or a body in kit form.
- Various arrangements have been proposed for connecting the fascia panel to the drawer body. Simple arrangements which serve permanently to secure the front panel on the drawer body, such as screwing the panel in position, are cheap to produce but do not permit for adjustment of the panel relative to the drawer body if assembly of the complete unit is not effected with the necessary degree of accuracy. More complex arrangements have been proposed which allow for adjustment of the panel relative to the drawer body. However, these arrangements tend to be relatively expensive to produce and are often difficult or awkward to assemble and adjust.
- The present invention seeks to provide a drawer having a connection between a drawer body and a fascia panel which is simple and cost-efficient to produce and assemble and which enables adjustment of the fascia panel relative to the drawer body, both vertically and horizontally, in a quick and simple manner.
- According to one aspect of this invention there is provided a kit of parts for forming a drawer, the kit comprising a drawer body and a fascia panel adapted to be mounted on the front of the drawer body, the fascia panel and the drawer body having means for releasably retaining the panel adjacent the front of the drawer body, part of the retaining means being movable between a first position in which the retaining means permit movement of the fascia panel relative to the drawer body and a second position in which said part of the retaining means locks the fascia panel in position relative to the drawer body; the kit further comprising means mountable on the drawer for moving said part of the retaining means to the second position.
- Preferably the releasable retaining means comprise a projection extending rearwardly of the fascia panel and a channel formed at the front of the drawer body, the channel defining an opening through which the projection may be introduced into the channel.
- Conveniently the channel extends substantially vertically and is formed at the front of a side wall of the drawer body, the channel having an opening extending into the front of the channel, through which part of the projection protrudes when the projection is inserted into the channel.
- Advantageously the projection is in the form of a connector element comprising a front portion and a rear portion, the front portion being received wholly within the channel and the rear portion protruding through said opening and being connected to the rear surface of the fascia panel.
- Preferably the front portion of the connector ele- mentcomprises a central region of reduced thickness, there being an aperture between said central region and the rear portion of the connector element, the central region constituting said part of the retaining means movable between said first and second positions.
- Conveniently the central region of the front portion of the connector element is connected to the remainder of the front portion by relatively thin, flexible webs of material.
- Advantageously the means for moving the central region of the front portion of the connector element between the first and second positions comprise a member introducible into the aperture between the central region of the front portion and the rear portion of the connector element, the thickness of the member being greater than the depth of the aperture between the central region and the rear portion of the connector element such that, upon insertion of the member into the aperture, said thin webs of material flex and the central region of the front portion of the connector element is moved away from the rear portion so as to project beyond the remainder of the front portion of the connector element and moves forcibly into engagement with a wall of the channel formed at the front of the drawer body when the connector element is received within that channel, thereby locking the fascia panel in position relative to the drawer body.
- Preferably the means for moving the central region of the front portion of the connector element between the first and second positions comprise a cover plate receivable within a shallow recess formed in a side wall of the drawer body, the cover plate carrying said member which is introducible into the aperture between the central region of the front portion of the connector element and the rear portion of the connector element, the shallow recess in the side wall having an aperture through which the member passes when it is to be introduced into the aperture in the connector element.
- Conveniently the shallow recess defines a further aperture and the cover plate carries a projection designed to be received in that further aperture as a snug fit so as to retain the cover plate in position within the shallow recess.
- Advantageously the central region of the front portion of the connector element and said wall of the channel define cooperating sets of teeth which are brought into engagement when the central region is forced into engagement with the wall, the sets of teeth serving to prevent movement of the fascia panel relative to the drawer body in one or more directions.
- The sets of teeth may serve to prevent vertical and horizontal movement of the fascia panel relative to the drawer body.
- According to a second aspect this invention provides a method of forming a drawer from a kit of parts as described above the method comprising the steps of connecting a projection to the rear surface of the fascia panel and inserting said projection into a channel formed at the front of the drawer body such that the panel is retained adjacent the front of the drawer body; mounting a member upon the drawer body so as to engage part of the projection and move said part of the projection from a first position in which the fascia panel may move relative to the drawer body to a second position in which the part of the projection locks the fascia panel in position relative to the drawer body.
- This invention further provides a drawer when formed from a kit of parts as described above, and an item of furniture incorporating such a drawer.
- In order that the present invention may be more readily understood, and so that further features thereof may be appreciated, the invention will now be described, by way of example, with reference to the accompanying drawings, in which:
- FIGURE 1 is a perspective view of a drawer body forming part of the present invention;

- FIGURE 10 is a cross-sectional view taken on the line X-X of Figure 9.
- A drawer in accordance with the present invention comprises a drawer body 1, as shown in Figure 1 of the drawings, and a fascia panel 2 (only part of which is shown in Figure 2) carrying, on its rear surface, a pair of connector elements 3 (only one of which is shown in Figure 2) and a pair of locking members 4, one of which is illustrated in Figure 3. The
connector elements 3 and the locking members 4 enable the fascia panel to be releasably mounted on the front of the drawer body 1. - The drawer body comprises an integrally moulded unit which is, in plan view, substantially square and comprises a
base 5,side walls 6 and a rear wall 7. Each of theside walls 6 are of similar form and extend outwardly at their upper edge in an arcuate manner and then extend downwardly as a dependingskirt 8 which turns inwardly before again extending downwardly to the level of thebase 5. Thus theskirt 8 has an upper portion extending over approximately two thirds the depth of the side wall and a lower portion which extends over approximately one third the height of the side wall. The region between each of theside walls 6 and theirrespective skirts 8 is hollow. - At the front of the drawer each
side wall 6 is connected to its associatedskirt 8 by way of avertical front wall 9, eachfront wall 9 defining arectangular opening 10 which extends upwardly from the base of the drawer (where it has an open mouth) over approximately three quarters of the height of the side wall. A furthervertical wall 11 extends between theside wall 6 and theskirt 8 at a position just behind thefront wall 9. Thewall 11 carries a set of vertically extending, parallel serrations orteeth 12 which are of a limited depth and are positioned just beneath the level of the upper edge of theopening 10. A horizontal set of teeth may be superimposed on thevertical teeth 12. Theteeth 12 are designed to cooperate with a corresponding set of teeth formed on part of eachconnector element 3. - It will be appreciated from the description given above and from Figures 1 and 4 of the drawings that the front end of each side wall of the drawer body defines a vertically extending, open bottomed channel which is of substantially T-shaped configuration when seen in horizontal cross-section, the head of the T being enclosed by the
side wall 6, thewall 11 and theskirt 8, whilst the stem of the T is defined between the edges of theopening 10. This channel is designed to receive aconnector element 3 which may be introduced into the channel via the open bottom thereof. - At the front end of each
skirt 8 at a position just above the point where it turns inwardly, the upper portion of the skirt defines a shallow, generallyrectangular recess 13. The recess defines two apertures, there being a first, rectangularupright aperture 14 positioned adjacent the front edge of the drawer and a second, elongated oval-shaped aperture 15 positioned behind theaperture 14 at a small distance therefrom. Theaperture 14 extends through theskirt 8 into the hollow region between the side wall and the skirt at a position in front of thewall 11 i.e. it extends into the T-shaped channel at the front of the side wall. Theaperture 15 extends through the skirt into the hollow between the skirt and the side wall at a position behind thewall 11. Theshallow recess 13 is aligned vertically with the set ofteeth 12 formed on thewall 11. The hollow region between theskirt 8 and theside wall 6 is accessible in the region of therecess 13 by way of an opening in theskirt 8 where the skirt turns inwardly. This opening is not visible in the drawings but allows a person's finger to enter behind the upper portion of theskirt 9 in the region of therecess 13. Eachrecess 13 is designed to receive a locking member 4. - Each locking member 4 comprises a planar, substantially
rectangular cover plate 16 of the same overall dimensions as therecess 13. The cover plate carries, adjacent one edge, a projection 17 which is of rectangular cross-section and which is dimensioned to pass through theaperture 14. The projection 17 defines a bevelledfree edge 18. Thecover plate 16 also carries an elongate oval-shaped projection 19 dimensioned to fit in theaperture 15. The free edge of theprojection 19 is also bevelled at 20. - Each
connector element 3 comprises an integrally moulded elongate component having a relativelywide front portion 21 designed to be received wholly within the T-shaped channel formed at the front edge of each side wall of the drawer body and a relatively narrowrear portion 22 designed to pass through the opening 10 in thefront wall 9. Therear portion 22 is located substantially centrally upon the rear of thefront portion 21 and extends over only part of the width and only part of the height of the front portion, as is most clearly visible in Figures 5 and 6 of the drawings. Therear portion 22 defines a flatrear surface 23 which lies flat on the rear surface of thefascia panel 2 when the connector element is mounted thereon. Each connector element defines a pair of vertically spaced apart,countersunk screw holes 24 through which screws may be passed in order to screw the connector element onto the rear surface of the fascia panel. Theholes 24 are countersunk so that the heads of the screws received within the holes lie substantially flush with or slightly below the front surface of the connector element. - The front portion of each connector element comprises three regions, there being an
upper region 25, acentral region 26 and alower region 27. - The
upper region 25 and thelower region 27 are of equal thickness and are interconnected at the rear by therear portion 22, whilst thecentral portion 26 is of lesser thickness such that anaperture 28 is defined between therear portion 22 and thecentral portion 26. The depth of theaperture 28 in a direction extending perpendicularly between therear portion 22 and the back of thecentral portion 26 is slightly less than the thickness of the projection 17 on the locking member 4. The height of theaperture 28 is slightly greater than the height of the projection 17. - The
upper region 25 and thelower region 27 are each connected to the central region by a relatively thin web ofmaterial 29 forming one side of the base of respective V-shapedgrooves 30 which extend transversely across the front surface of thefront portion 21 at the upper and lower borders of thecentral portion 26. The front surface of thecentral portion 26 carries a set of vertical,parallel teeth 31 designed to engage with theteeth 12 formed on thewall 11 in the drawer body. A set of horizontal teeth may be superimposed on thehorizontal teeth 31. - It is envisaged that the
connector elements 3 will be formed from polypropylene and thewebs 29 will be sufficiently thin to enable them to flex slightly so that thecentral portion 26 may be urged away from therear portion 21 thereby causing the surface carrying theteeth 31 to project beyond the plane of the front surface of the connector. - The screw holes 24 are located in the upper and lower regions of the front portion at positions immediately adjacent the V-shaped
grooves 30. Thelower portion 27 has one side face which defines aninturned step 32 in similar manner to that which is defined by theskirt 8 on the drawer body. Thus, the lowermost section of thelower portion 27 is of lesser width than the remainder of the front portion of the connector element. - In use it will be appreciated that the two
connector elements 3 are screwed onto the rear of afascia panel 2 at predetermined positions spaced across the width of the panel, the spacing corresponding to the distance between the T-shaped channels defined at the front of the side walls of the drawer body. The panel is then mounted on the front of the drawer body by introducing theconnector elements 3 into the T-shaped channels at the front of the side walls of the drawer body. The connector elements are introduced into these channels by way of its open bottom, with thefront portion 21 of each connector element being received between thewalls rear portion 22 of each connector element projecting through theopening 10. When the connector elements are fully inserted into the T-shaped channels theteeth 31 on each connector element are aligned with, but spaced slightly from theteeth 12 formed on thewall 11. - The two locking members 4 are now each inserted into a
respective recess 13 on either side of the drawer body such that the projection 17 passes through theaperture 14 and theprojection 19 extends into theaperture 15. The projection 17 passes into theaperture 28 and because that projection is of greater thickness than the depth of the aperture, that projection urges thecentral portion 26 away from therear portion 22 and causes theteeth 31 to move into engagement with the correspondingteeth 12. Thebevelled edge 18 at the free end of the projection 17 facilitates the insertion of the projection into theaperture 28 behind thecentral portion 26. - When the locking member 4 is fully inserted the
cover plate 16 is received with in theshallow recess 13 and lies substantially flush with the surface of theskirt 8, whilst theprojection 19 is a tight fit within theaperture 15. Thebevelled edge 20 on theprojection 19 facilitates the introduction of that projection into theaperture 15. When both locking members 4 have been inserted thefascia panel 2 is securely mounted upon the front of the drawer body with the two sets ofteeth central portion 26 and thewall 11 serving to prevent vertical movement of the panel relative to the drawer body. If horizontal sets of teeth are superimposed on thevertical teeth - If it is necessary to adjust the position of the fascia panel relative to the drawer body or to remove the fascia panel from the front of the drawer body then the locking members 4 can be released by pushing them out of their
respective recesses 13. This is effected by passing a finger behind theskirt 8 at a position adjacent therecess 13 and pushing on the free end of theprojection 19 so as to force the locking member 4 out of therecess 13. As the locking member 4 moves out of therecess 13 so the projection 17 is withdrawn from theaperture 28 and the sets ofteeth - It is to be noted that when the
connector elements 3 are fully inserted within the T-shaped channels and the sets of teeth are aligned the wider section of thefront portion 21 of each connector element is received within the channel at a position above the level of the step in theskirt 8. If theconnector elements 3 are lowered from the fully introduced position then the wider section of thefront portion 21 of each connector element will just pass through the lower portion of the T-shaped channel but no significant sideways movement of the panel will be possible relative to the drawer body unless the connector elements are fully inserted within the T-shaped channels. - It is envisaged that the connector elements and the channels within which they are received will be provided with cooperating means to enable the fascia panel to be supported upon the front of the drawer body before the locking members 4 have been placed in position. Thus, the connector elements and the channels may be provided with cooperating projections and recesses which form a flexible snap-fitting connection which supports the connector elements within the channels and thereby supports the fascia panel upon the front of the drawer body. The
step 32 on the front portion of each connector element already serves this purpose to a certain degree, in that the step enables the connector to rest upon the corresponding step formed in theskirt 8. However there is no positive retention of the fascia panel in position relative to the drawer body with this arrangement. Similarly the locking members 4 may well be provided with means for retaining the locking members in position relative to the recess before the locking members have been fully inserted. It will still be possible to adjust the position of the fascia panel both vertically and horizontally relative to the drawer body when the panel is supported upon the front of the drawer body in this way and when the locking members 4 are supported in position relative to therecesses 13. - Figures 7 to 10 illustrate modified components for enabling a fascia panel to be mounted upon the front of a drawer body. Figure 7 illustrates the front end only of one
side wall 33 of a drawer body supplied in kit form. The complete drawer body would comprise a base, a pair of side walls, a front wall and a rear wall. I some cases the front wall may be omitted and a fascia panel can be mounted directly on the front ends of theside walls 33. Alternatively the rear of a fascia panel may carry the front wall of the drawer body which is in turn mounted on the front end of theside walls 33. The modified arrangement of Figures 7 to 10 comprises the same basic components as previously described and thus the front end of eachside wall 33 is designed to receive aconnector element 34 mounted on the rear of a fascia panel, with eachconnector element 34 being positively retained in position relative to the front end of the its associatedside wall 33 by means of a lockingmember 35. - The main difference between the modified arrangement of Figures 7 to 10 and that of Figures 1 to 6 is that the front end of each
side wall 33 has been modified to take account of the fact that the drawer body is to be provided in kit form and, as can be seen from Figure 7, the front end of each side wall defines a vertically extendingchannel 36 between inner andouter walls vertical wall 39 extending between the inner andouter walls vertical wall 39 being spaced rearwardly of a furthervertical wall 40 which is positioned adjacent the front end of the side wall and which defines anopening 41 extending into thechannel 36 from the front end of the side wall. Theopening 41 has afirst portion 42 which extends across approximately half of the width of the side wall and which is of greater height than asecond portion 43 of the opening which extends across the other half of the width of the front wall. The second portion of theopening 41 is formed with a projectingrim 44 around three of its sides. It will be appreciated that the lowermost portion of thevertical wall 40 forms a web extending between the inner andouter walls side wall 33 and this web prevents the insertion of aconnector element 34 into thechannel 36 via the open end of thechannel 36 adjacent the base of the side wall when the connector element is mounted on the rear of the fascia panel. - In similar manner to the previously described embodiment, the front end of the
side wall 33 defines ashallow recess 45 which is designed to receive the lockingmember 35. In the modified embodiment therecess 45 is generally L-shaped, having a portion which extends vertically at the front end of the side wall and a portion which extends horizontally from the front end towards the rear of the side wall adjacent the upper edge thereof. Within the recessedarea 45 theouter wall 38 defines a rectangular upright aperture 46 which extends into thechannel 36 in similar manner to theaperture 14 of the previous embodiment. The aperture 46 is aligned with a set ofteeth 47 formed on thevertical wall 39 constituting the base of thechannel 36. - Each locking
member 35 comprises a generally L-shaped portion designed to be received within the recessedarea 45 formed on the outwardly directed face of theside wall 33 and aportion 48 which extends perpendicularly thereto, theportion 48 being designed to extend across the front end of theside wall 33 when the locking member is in place. Theportion 48 defines a cut awayregion 49 which is designed to be aligned with theopening 41 when the locking member is in place. As with the previously described locking member, the lockingmember 35 effectively forms a cover plate and carries aprojection 50 which is of rectangular cross-section and which is dimensioned to pass through the aperture 46. Theprojection 50 has a bevellededge 51 which facilitates the mounting of a fascia panel on the front end of the drawer body. - The
connector elements 34 are of very similar design to theconnector elements 3 which have been described above and thus comprise afront portion 52 which is dimensioned to pass through thefirst portion 42 of theopening 41 with a small clearance and arear portion 53 which is of lesser height than the front portion and which is dimensioned so that it will just pass through thesecond portion 43 of theopening 41 with a small clearance. As can clearly be seen from Figures 9 and 10 of the drawings the front portion and the rear portion of eachconnector 34 are of the same width and each portion is of generally rectangular shape. Each connector element defines a pair of screw holes 54 by way of which the element is designed to be mounted upon the rear of a fascia panel or upon the rear of the front wall of a drawer body which is itself mounted on the rear of a fascia panel. - The
front portion 52 of each connector element is of the same design as the front portion of theconnector element 3 described above and will therefore not be described in detail again other than to say that it comprises a central region 55 which is spaced from the rear of the connector by anaperture 56, the central region being connected to the remainder of the connector element by thin webs ofmaterial 57 which can flex slightly so as to permit the central portion 55 to be urged away from therear portion 53 of the connector element. The front surface of the central region 55 again carries a set ofteeth 58 designed to cooperate with theteeth 47 formed on the base of thechannel 36. Thus, as thewebs 57 flex and the central portion 55 is urged away from therear portion 53 of the connector element theteeth 58 project beyond the plane of the front surface of the connector. - In use two
connector elements 34 are mounted on the rear of a fascia panel or on the rear of a front wall of a drawer body which is itself mounted on the rear of a fascia panel so that the spacing between the connector elements corresponds to the spacing between theside walls 33 of the drawer body to which the fascia panel is to be connected. The panel (and the front wall of the drawer body if this is mounted on the rear of the panel) is then mounted on the front of eachside wall 33 by introducing theconnector elements 34 into thechannel 36 through theopening 41. - It will be appreciated that in contrast to the previously described embodiment the connector elements are introduced into the channel not via the opening adjacent the base of the side wall but via the opening formed at the front of the side wall i.e. by pushing the connector elements into the channel in a direction towards the rear of the drawer body. The connector elements are inserted into the channel by passing the elements through the
first portion 42 of the opening whereupon the fascia panel and the connector elements can be moved laterally such that thefront portion 52 of each connector element is received behind thevertical wall 40 with therear portion 53 of each connector element projecting out through thesecond portion 43 of theopening 41. Therear portion 53 of each connector element now rests upon theprojection 44 formed around the periphery of thesecond portion 43 of theopening 41 and when the fascia panel is correctly positioned relative to the drawer body the lockingmembers 35 can be located in position on eachside wall 33. - Each locking member is offered up to the side wall by introducing the
projection 50 into the aperture 46. As theprojection 50 passes through the aperture 46 it is automatically directed into theaperture 56 between the front and rear portions of theconnector element 34. Theprojection 50 has a thickness which is slightly greater than the distance between the front and rear portions of theconnector element 34 and thus theprojection 50 urges the central portion 55 away from therear portion 53 and causes theteeth 58 to move into engagement with the correspondingteeth 47. Thebevelled edge 51 on theprojection 50 facilitates the insertion of the projection into theaperture 56 defined by the connector element. The fascia panel is now effectively locked in place on the front of the drawer body and the lockingmember 35 is received within the recessedarea 45 with itsfront portion 48 extending across the front of theside wall 33. - If necessary the rearwardly extending portion of the L-shaped locking member may carry a further projection designed to be received within a further aperture formed in the
outer wall 38 in similar manner to theprojection 19 which is received in theaperture 15 in the embodiment described previously. This would serve to ensure that the locking member is retained securely in position within the recessedarea 45. - As previously described the
teeth wall 39 defining the base of the channel prevent vertical movement of the panel relative to the drawer body. As previously mentioned horizontal sets of teeth could be superimposed upon thevertical teeth - Adjusting the position of the fascia panel relative to the drawer body can be effected in the same manner as described above by simply removing the locking
members 35 adjusting the position of the panel as necessary and then replacing the locking members. - Whilst this invention has been described with reference to specific embodiments, it will be appreciated that various modifications may be made to those embodiments without departing from the scope of the present invention.
