Description

  The present invention relates to an elevating type hanging cupboard installed above a kitchen.

  In kitchens, there is often a space above the cooking equipment such as a kitchen, so a hanging cupboard is often installed above the kitchen. In the kitchen, a variety of items are used, such as dishes such as rice cakes, dishes and cups, cooking utensils such as pots and pans, and seasonings such as salt and pepper. For this reason, these tableware, cooking utensils, seasonings, etc. are stored in the said hanging cupboard.

  In addition, with the diversification of lifestyles and eating habits, the above-mentioned tableware, cooking utensils, seasonings and the like are on an increasing trend. Furthermore, with recent aging, there is also a demand for ease of use and convenience of the above hanging cabinet.

  In view of this, there has been proposed an elevating-type hanging door shelf that raises or lowers a shelf (rack) that is normally positioned above manually or electrically. Various configurations have been proposed for raising and lowering the rack, and among them, a configuration including a cabinet and a lifting rack that can be raised and lowered substantially vertically from the cabinet is proposed (for example, Patent Document 1). .

However, in the configuration in which the lifting rack is raised and lowered in the vertical direction, in order to expose the entire surface of the lifting rack, a stroke for lowering the entire lifting rack below the cabinet is required. Therefore, conventionally, a configuration has been disclosed in which the front door of the cabinet is opened and closed in conjunction with the vertical movement of the lifting rack, and the upper end of the lifting rack is above the lower end of the cabinet when the lifting rack is lowered (for example, Patent Document 2). According to this configuration, it is possible to put in and out from a position that should be hidden by the front door, so the height of the lifting rack can be increased, and a large lifting rack is installed in the upper space of a limited height. can do.

  However, in the configuration described in Patent Document 2, since the lower end of the door is rotated and opened, the front open space is small. For this reason, there is a problem that it is difficult to put in and out large items such as pots and boxes, especially in the upper stage of the lifting rack. Although it is conceivable to open the door further wide, since the door protrudes greatly in front of the hanging cabinet, the front plate approaches the head, which may give a feeling of pressure.

  Moreover, when it is set as the structure which a door moves, the rattling of a door becomes a problem. Although the cabinets are relatively large, the cabinets are not rigid enough to cause overall distortion. Especially when attached to the wall of a building, the wall distortion is transferred to the cabinet. For this reason, if the clearance between the members is excessively increased, the members may be engaged with each other due to distortion, which may cause malfunction (a trouble caused in movement of the door). On the other hand, if the play increases, there is inevitably rattling, which may cause abnormal noise during operation, instability, and malfunction.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an elevating type hanging cabinet that shortens the stroke for lowering the elevating rack to increase the volume while minimizing the rattling of the door, which is a movable member.

  In order to solve the above-mentioned problem, a typical configuration of an elevating-type hanging cabinet according to the present invention includes a cabinet whose bottom surface and front surface are open, and an elevating rack supported so as to be movable up and down with respect to the cabinet. In an elevating type hanging cabinet installed above the kitchen, an upper door disposed on the front and upper side of the cabinet, a door member disposed on the front and lower side of the cabinet, a towing unit for raising and lowering the door member, and a door member And a guide fitting having a guide for guiding the guided portion, which is arranged on each side wall of the cabinet. And a spacer member disposed in a gap between the first and second spacers.

  According to the above configuration, since the spacer member is provided between the guide member attached to the cabinet and the connecting fitting attached to the door member, the rattling of the cabinet is minimized while allowing the cabinet to be distorted. Can be limited.

  The guide is a groove provided in the guide metal fitting, and the guided portion is a pulley fitted to the guide. By setting it as such a structure, since a guide metal fitting and a connection metal fitting move in parallel, shakiness can be effectively absorbed by a spacer member.

  The spacer member may have a thickness substantially equal to the gap between the connection fitting and the guide fitting, and the spacer member may be configured to slide in contact with the connection fitting or the guide fitting when the door member moves up and down.

  Furthermore, the spacer member may be disposed at least on the front side of the guide and on the back side of the guide. Thereby, not only the rattling in the left-right direction but also the oblique deformation can be prevented, so that the rigidity can be further improved.

  At this time, the spacer member arranged on the front side of the guide has a thickness substantially equal to the gap between the connecting metal fitting and the guide fitting, and the spacer member arranged on the back side of the guide has a thickness slightly smaller than the gap. Also good. Assembling can be improved by preventing backlash accurately on the front side and allowing a little play on the back side.

  The spacer member can be formed of a resin block material. As an example of the resin material, a crystalline resin having low slidability such as polypropylene, polycarbonate, polyacetal, or the like can be suitably used.

  The guide may include an inclined portion that guides the guided portion toward the front of the cabinet as it goes upward from its stop position, and a linear portion that guides the inclined portion in a substantially vertical direction. According to the above configuration, as the door member moves upward, the inclined portion first moves to the front of the cabinet and then rises along the front side of the cabinet. Therefore, the amount of protrusion of the door member to the front side can be minimized.

  ADVANTAGE OF THE INVENTION According to this invention, the raising / lowering hanging shelf which kept the backlash of the door which is a movable member to the minimum can be provided, shortening the stroke which lowers a raising / lowering rack and aiming at the increase in volume.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol. Note that dimensions, materials, and other specific numerical values shown in the following embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified.

  In the present embodiment, the lifting rack of the kitchen lifting cabinet (hereinafter abbreviated as “hanging cabinet”) and the lower door that covers the front of the lifting rack are interlocked to move both devices in opposite directions. . Therefore, a sufficient open space on the front surface can be ensured without increasing the descending stroke of the lifting rack. The lower door is characterized in that it goes around the lower end of the upper door when it rises and rises along its surface. Here, in order to facilitate understanding of the present embodiment, the arrangement of the hanging cabinet and the drive mechanism will be described first, and then the features of the present embodiment will be described in detail.

  FIG. 1 is a perspective view showing the positional relationship between the system kitchen and the hanging cupboard of this embodiment. In the system kitchen 100, cooking utensils such as fire (heating) and water necessary for cooking are arranged in each storage according to the size. Although the hanging cupboard 110 is installed above the system kitchen 100, the storage part is lowered to the level of the eyes of the kitchen user without opening and closing the door in the high place, and the object is stored by reaching forward. Can be stored or taken out.

  The system kitchen 100 is composed of roughly three parts: a sink 130, a cooking space 140, and a stove 150. In the system kitchen 100, the hanging cupboard 110 is fixedly supported on the back surface of the wall 500 above the region extending across the width of the sink 130 and the cooking space 140. On the other hand, a range hood 160 is fixedly supported on the wall 500 in the same manner as the hanging cabinet, adjacent to the hanging cabinet 110, above the stove 150 that handles fire.

  The hanging cabinet 110 includes a cabinet 170 that is open at the bottom and a lifting rack 180 that moves up and down the cabinet 170 below the cabinet 170. The lifting rack 180 has a storage portion, and most of the front surface is open so that dishes and articles around the kitchen can be taken in and out.

  In the present embodiment, the front surface of the cabinet 170 includes an upper door 172 disposed above and a lower door 174 disposed below as door members. When the lifting rack 180 descends and appears below the cabinet 170, the lower door 174 moves upward in conjunction with this. Therefore, even if the upper end of the lifting rack 180 does not descend from the lower end of the cabinet 170, the open front of the lifting rack 180 appears in front of the user. With this configuration, the movable range of the lifting rack 180 can be narrowed, the lifting operation time can be shortened, and the height of the lifting rack 180 can be increased to increase the volume. A drive mechanism for interlocking the lifting rack 180 and the lower door 174 will be described below.

(Driving rack drive mechanism)
FIG. 2 is a view showing a drive mechanism of the lifting rack 180. Here, observation is mainly made from the front side of the hanging cupboard 110 in order to explain the lifting operation of the lifting rack 180. In order to facilitate understanding, the lower door 174 is not shown in FIG.

  First, by the rotation of the drive motor 190, the two wide rope bodies 200 are unwound from the drive pulley 192 to the left and right in the horizontal direction. The wide cable body 200 is fixedly installed in the vicinity of both side plates of the cabinet 170 and turned in a vertical direction by a turning pulley 210 that functions as a fixed pulley, and ends thereof are fixed to a lifting rack 180 and each of the lifting pulleys functions as a moving pulley. 212 is wound and fixed above the cabinet 170. Therefore, the elevating rack 180 can be raised and lowered by rotationally driving the drive motor 190. Here, the rope includes not only the rope but also a belt.

  When the lifting rack 180 is lowered in this manner, the storage unit 220 appears from the back surface of the lower door 174 (not shown).

(Lower door drive mechanism)
FIG. 3 is a view showing a drive mechanism (traction section) of the lower door 174 that is linked to the lifting rack 180. In FIG. 3, the hanging cupboard 110 is observed from the side. Here, the lower door 174 moves up and down in conjunction with the lifting rack 180 shown in FIG.

  FIG. 3A shows a state where the lifting rack 180 is stored in the cabinet 170. A lower door pulley 250 as a fixed pulley is fixedly installed between the lifting rack 180 and the lower door 174. The lower door pulley 250 is rotatably supported with two shafts (first reel 252 and second reel 254) connected to each other with the same shaft. The first reel 252 is wound with a first rope 260 that suspends the lifting rack 180, and the second reel 254 is wound with a second rope 262 that suspends the lower door 174.

  Here, the first cable body 260 and the second cable body 262 that respectively suspend the lifting rack 180 and the lower door 174 are wound around the reel in reverse rotation, so the lifting rack 180 or the lower door 174 is wound. When one of the rises, the other interlocks and falls due to its own weight.

  FIG. 3B shows a state where the lifting rack 180 is pulled out (lowered) from the cabinet 170. When the lifting rack 180 is lowered while being guided by the guide rail 264, the first rope 260 pulls the first reel 252, and the second reel 254 connected to the first reel 252 is centered around the rotation shaft 256 and the first reel 252. Rotate by the same angle as. Then, the coupling fitting 266 and the lower door 174 connected to the second rope body 262 are raised by the winding tension of the second reel 254. Accordingly, the lower door 174 rises in accordance with the lowering of the lifting rack 180, and the sum of the movement amounts becomes an opening space of the lifting rack 180. Therefore, a sufficient opening space on the front surface of the lifting rack 180 can be obtained without increasing the lowering stroke. It can be secured.

(Lower door guide mechanism)
Next, the guide mechanism and operation of the lower door will be described. FIG. 4 is a diagram for explaining a lower door guide mechanism.

  FIG. 4A is an exploded view for explaining the guide mechanism. Door drive fittings 176 for attaching the lower door 174 to the connecting fitting 266 are respectively attached to the back surfaces of both side edges of the lower door 174. The connecting metal fitting 266 is provided with an upper roller 268 and a lower roller 270 which are guided portions. In addition, a suspended portion 272 for attaching the second cord body 262 is provided at the upper end of the connection fitting 266. A guide fitting 280 is provided on each side wall of the cabinet 170. The guide fitting 280 is provided with an upper guide 282 for guiding the upper roller 268 and a lower guide 284 for guiding the lower roller 270. The guide fitting 280 is provided with a storage mechanism 390 described later.

  The guide fitting 280 is a plate-like body, and the upper guide 282 and the lower guide 284 are long holes provided in the guide fitting. Large diameter portions 282a and 284a are formed at the lower ends of the upper guide 282 and the lower guide 284, respectively, and the heads of the upper roller 268 and the lower roller 270 can be inserted. The upper roller 268 and the lower roller 270 are thread-wound pulleys having grooves on their end surfaces, and are guided to move by being fitted to the long hole edges of the upper guide 282 and the lower guide 284.

  Further, the upper guide 282 and the lower guide 284 are inclined portions 282b and 284b that are guided toward the front of the cabinet 170 as they go upward from a stop position (substantially lower end position) of the upper roller 268 or the lower roller 270, and an inclined portion. 282b and 284b are provided with linear portions 282c and 284c that guide in a substantially vertical direction.

  Since the upper guide 282 and the lower guide 284 have the above shapes, as the lower door 174 is moved upward, the lower door 174 is first moved forward by the inclined portions 282b and 284b, and then is linearly moved. Ascending along the front side of the upper door 172 by the portions 282c and 284c. As a result, the lower door 174 can go around the lower end of the upper door 172 and rise along the surface thereof.

  FIG. 4B is an assembly view of the guide mechanism. The upper roller 268 and the lower roller 270 are slidably movable by fitting their heads to the upper guide 282 and the lower guide 284. A second cable body 262 is attached to the suspended portion 272 of the connection fitting 266, and the lower door 174 is stopped by being suspended. The second cable body 262 pulls the connection fitting 266 upward from this stop position, whereby the lower door 174 is raised while the upper roller 268 and the lower roller 270 are guided by the upper guide 282 and the lower guide 284.

(Rattle prevention mechanism)
FIG. 5 is a perspective view for explaining the guide mechanism of the lower door. As shown in FIGS. 4 and 5, in the present embodiment, spacer members 286 and 288 are provided in the gap between the connection fitting 266 and the guide fitting 280. FIG. 5 is a perspective view for explaining the configuration of the connection fitting 266 and the guide fitting 280. The spacer member 286 is attached and fixed to the guide metal fitting side of the connecting metal fitting 266, and is disposed on the back side of the guide (upper guide 282 and lower guide 284). The spacer member 288 is fixedly attached to the connecting metal side of the guide metal 280 and is disposed on the front side of the guide. The spacer members 286 and 288 may be attached to either the connection fitting 266 or the guide fitting 280.

  The spacer members 286 and 288 are resin block members having a thickness substantially equal to the gap between the connection fitting 266 and the guide fitting 280. When the lower door 174 moves up and down, the spacer member 286 is configured to slide in contact with the connection fitting 266 or the guide fitting 280.

  According to the above configuration, since the connecting metal fitting 266 and the guide metal fitting 280 do not slide directly, even if the cabinet 170 is distorted, they are not engaged with each other. Nevertheless, since these gaps can be filled by the spacer members 286 and 288, that is, while allowing the cabinet, rattling of the lower door 174 can be minimized.

  In particular, since the upper guide 282 and the lower guide 284 are grooves provided in the guide fitting 280 and the upper roller 268 and the lower roller 270 are pulleys, the connecting fitting 266 and the guide fitting 280 are translated. Therefore, rattling can be effectively absorbed by the spacer members 286 and 288 having the above-described configuration.

  In addition, since the spacer members are arranged on both the front side and the back side of the guides (the upper guide 282 and the lower guide 284), not only horizontal shaking but also oblique deformation can be prevented, so that the rigidity is more rigid. Can be improved. At this time, the spacer member 288 disposed on the front side of the guide may have a thickness substantially equal to the gap, and the spacer member 286 disposed on the back side may have a thickness slightly smaller than the gap. As a result, it is possible to improve the assemblability by preventing backlash accurately on the front side and allowing a little play on the back side.

  Note that a resin material can be used for the spacer members 286 and 288, and specific examples of the spacer members 286 and 288 can preferably be a crystalline resin having low slidability such as polypropylene, polycarbonate, and polyacetal.

  FIG. 6 is a diagram illustrating the operation of the lower door, and the operation of the lower door will be described with reference to the shape of the guide in FIG.

  FIG. 6A shows a state at the stop position. The lower door 174 is started by being pulled by the second cord body 262 from this state. At this time, as shown in FIG. 4B, the inclined portion 282b of the upper guide 282 has a larger inclination with respect to the vertical line than the inclined portion 284b of the lower guide 284. As a result, as shown in FIG. 6B, the upper end of the lower door 174 starts moving toward the front of the cabinet earlier than the lower end. Then, as shown in FIG. 6C, when the upper end of the lower door 174 moves further forward than the lower end of the upper door 172, the upper roller 268 and the lower roller 270 reach the straight portions 282c and 284c, and FIG. ) Ascending starts as shown in And if it raises to the upper end of straight part 282c, 284c, as shown in Drawing 6 (e), it will be in the state where the upper side of lower door 174 and the lower side of upper door 172 overlap.

  FIG. 7 is a diagram illustrating the trajectories of the lower door 174, the connecting metal fitting 266, the upper roller 268, and the lower roller 270. Referring to FIG. 7, it can be seen that the upper end of the lower door 174 wraps around the lower end of the upper door 172, and the lower door 174 rises along the surface of the upper door 172.

  After the upper roller 268 and the lower roller 270 reach the straight portions 282c and 284c, the posture (inclination angle) of the lower door 174 rises without change. Here, as shown in FIG. 4B, the horizontal distance from the stop position of the upper roller 268 in the upper guide 282 to the straight portion 282c is the overhang width w1, and from the stop position of the lower roller 270 in the lower guide 284 to the straight portion 284c. Is the overhang width w2. In this embodiment, the overhang width w1 of the upper guide is set longer than the overhang width w2 of the lower guide.

  As a result, the lower door 174 rises in a tilted state where the upper end protrudes more toward the front of the cabinet, and the posture is maintained while it is stopped. As a result, it is possible to secure a maximum wide space above the user's head and to prevent the lower door from giving a feeling of pressure.

  When the lower door 174 is closed, that is, when the elevating rack 180 is raised, the lower door 174 descends following the ascending process shown in FIG. 6 and is stored below the upper door 172. At this time, it is reliably closed to the end by the operation of the accommodation mechanism 390.

  The configuration and operation of the accommodation mechanism 390 will be described. As shown in FIG. 4A, the accommodation mechanism 390 is provided on the upper part of the guide metal fitting 280, an arm 390a pivotally supported by the guide metal fitting 280 in a midway portion, and a roller 390b provided at one end of the arm. And a spring 390c (biasing means) for urging the roller 390b toward the inside of the cabinet. On the other hand, the connection fitting 266 is provided with an accommodation guide 266a for the roller 390b of the accommodation mechanism 390 to travel. The housing guide 266a has a U-shaped groove shape, and the roller 390b abuts against the side wall of the housing guide 266a, so that the connection fitting 266 can be urged toward the inside of the cabinet.

  When the lower door 174 is lifted as described above, as shown in FIG. 6, since the roller 390b is in contact with the side wall of the storage guide 266a, the storage mechanism 390 rotates against the urging force of the spring 390c. . When the upper roller 268 and the lower roller 270 are in the straight portion, the urging force of the accommodation mechanism 390 is substantially perpendicular to the direction of the guide groove, and thus there is no possibility of hindering the ascending force. When the lower door 174 is closed, especially when the upper roller 268 and the lower roller 270 are on the inclined portions 282b and 284b, the urging force of the spring 390c of the storage mechanism 390 acts in the direction in which the lower door 174 is stored.

  Here, if the lower door 174 is to be closed only by its own weight, when the upper roller 268 and the lower roller 270 are in the inclined portions 282b and 284b, the force in the housing direction is weakened because of the component force. For this reason, the lower door 174 is not closed to the end, and the movement may end in a state where the lower door 174 is slightly lifted from the upper door 172. However, since the housing mechanism 390 having the above-described configuration is provided, the upper end of the connecting metal fitting 266 is urged toward the inside of the cabinet 170, so that the lower door 174 can be reliably housed below the upper door 172. .

  As described above, the hanging cabinet 110 according to the present embodiment can sufficiently secure an open space on the front surface without increasing the lowering stroke of the lifting rack 180, and shortening the stroke for lowering the lifting rack to reduce the volume. Can be increased. In addition, by arranging the spacer member in the gap between the connecting metal fitting and the guide metal fitting, it is possible to minimize the rattling of the door, which is a movable member, and to improve the ease of use of the kitchen lifting rack. .

  Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used as an elevating type hanging cabinet installed above a kitchen.
