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. The lifting-type hanging cabinet is, for example, the one that the entire hanging cabinet is raised or lowered (for example, Patent Document 1), or the storage shelf installed in the hanging cabinet is supported by a rotating arm after opening the door arranged in front of the hanging cabinet. There are those that are pulled down to the front side and lower (for example, Patent Document 2), cabinets, and those that have a lifting rack that can be lifted and lowered in a substantially vertical direction from the cabinet (for example, Patent Document 3).

  In the configuration described in Patent Document 1, there is a problem that the entire lifting cabinet is moved up and down, so that the lifting device becomes large, and the driving mechanism is visible from the outside, so that it is difficult to improve the aesthetics. Moreover, in the structure described in patent document 2, since the pulled-down storage shelf rotates and descends toward a chef, it becomes a hindrance to cooking work and must frequently put in and out the storage shelf. There is a problem that it takes time and effort. For this reason, in recent years, as described in Patent Document 3, a configuration including a lifting rack that can be lifted and lowered in a substantially vertical direction from a cabinet has been widely adopted.

  However, in the configuration in which the lifting / lowering rack is vertically moved, in order to expose the entire surface of the lifting / lowering rack, a stroke for lowering the entire lifting / lowering rack to the lower side of the cabinet is required below the cabinet. In other words, only half the height of the space available for the hanging cupboard from the top of the kitchen to the ceiling can be installed. In fact, since the drive mechanism for raising and lowering must be provided in the cabinet, the volume of the raising and lowering rack is further reduced. In addition, the ceiling height of a general home is generally about 2.3 m, and the height of the kitchen is about 85 cm. In addition, there must be enough room above the kitchen to hold the bins and accessory racks. If the height of the lifting rack is equal to or less than half the height of the remaining upper space, it cannot be said that the volume of the lifting rack is sufficient.

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 4). 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 4, since the lower end of the door is rotated and opened, the open space on the front surface 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.

  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 feeling of pressure associated with the operation of the door.

In order to solve the above-mentioned problems, a typical structure of a lifting cabinet according to the present invention includes a cabinet having a bottom surface and a front surface that are open, and a lifting rack supported so as to be movable up and down with respect to the cabinet. In the elevating-type hanging cabinet installed above the upper door, the upper door that is disposed on the front and upper side of the cabinet, and the lower door that is disposed on the front and lower side of the cabinet, the lower door wraps around the lower end of the upper door, The upper guide and the lower guided portion can be raised along the surface, and are provided with an upper guided portion and a lower guided portion on each side edge of the lower door, and guide the upper guided portion on each side wall of the cabinet. The upper guide and the lower guide are inclined to guide the upper guided portion or the lower guided portion toward the front of the cabinet as it goes upward from its stop position. If, in succession to the inclined portion and a straight portion for guiding the substantially vertical direction, towards the inclined portion of the upper guide, and wherein a greater inclination with respect to a vertical line than the inclined portion of the lower guide.

  According to the above-described configuration, it is possible to provide an elevating-type hanging cabinet that shortens the stroke for lowering the elevating rack to increase the volume and minimizes the feeling of pressure associated with the operation of the door.

In addition, as described above, the elevating type hanging cabinet according to the present invention is provided with an upper guided portion and a lower guided portion on each side edge of the lower door, and guides the upper guided portion on each side wall of the cabinet. A guide and a lower guide for guiding the lower guided portion are provided, and the upper guide and the lower guide guide the upper guided portion or the lower guided portion toward the front of the cabinet as they go upward from the stop position. an inclined portion, continuous to the inclined portion that has a straight portion for guiding the substantially vertical direction.

  According to the above configuration, as the lower door moves upward, the inclined portion first moves to the front of the cabinet and then rises along the front side of the upper door. Thereby, the lower door can go around the lower end of the upper door and rise along the surface thereof.

Furthermore, in the lifting type hanging cabinet of the present invention, the inclined portion of the upper guide has a larger inclination with respect to the vertical line than the inclined portion of the lower guide . Thereby, the upper end moves to the front of the cabinet earlier than the lower end of the lower door, and the lower end of the upper door can be smoothly wound around.

In order to solve the above-mentioned problem, another structure of the lifting type hanging cabinet according to the present invention includes a cabinet having a bottom surface and a front surface opened, and a lifting rack supported so as to be movable up and down with respect to the cabinet. In the up-and-down hanging cabinet installed above, it comprises an upper door arranged at the front and upper side of the cabinet and a lower door arranged at the front and lower side of the cabinet, the lower door wraps around the lower end of the upper door, An upper guide and a lower guided portion that can be raised along the surface, are provided with an upper guided portion and a lower guided portion on each side edge of the lower door, and guide the upper guided portion on each side wall of the cabinet. A lower guide for guiding the upper guide and the lower guide, and an inclined portion for guiding the upper guided portion or the lower guided portion toward the front of the cabinet as it goes upward from its stop position. Continuously to the inclined portion and a straight portion for guiding the substantially vertical direction, when the width overhanging the horizontal distance to the straight portion at the upper guide or the lower guide from the stop position of the upper guided portion or the lower guided portions , overhang the width of the upper guide is characterized in that longer than the overhang width of the lower guide. As a result, the lower door rises in an inclined state in which the upper end protrudes more. Therefore, it is possible to secure a wide space as much as possible above the user's head, and to prevent the lower door from giving a feeling of pressure.

  In addition, a pulling unit that pulls and raises the lower door may be provided, and the lower door may be lowered by its own weight by releasing the pulling by the pulling unit. Although driving by a motor and a gear is conceivable, according to the configuration of the rail and the guided portion, it can be moved up and down by pulling upward and descending by its own weight, and the drive mechanism can be simplified.

  The towing unit may be constituted by a pulley and a cable body that suspends the lifting rack and the lower door at both ends via the pulley, and may be configured to pull the lower door by a load when the lifting rack is lowered. Thereby, since the lifting rack and the lower door are mechanically interlocked, the driving force for lifting the lower door can be provided by the driving source of the lifting rack.

  ADVANTAGE OF THE INVENTION According to this invention, the raising / lowering type hanging shelf which can hold down the feeling of the pressure accompanying the operation | movement of a door 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 addition, an upper door 172 and a lower door 174 are arranged on the front surface of the cabinet 170. When the lifting rack 180 is lowered and appears below the cabinet 170, the lower door 174 is moved upward in conjunction with this. Moving. 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 hanging rack 110 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 connecting portion 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.

  At this time, since the loads on the lifting rack 180 and the lower door 174 are applied to each other around the rotating shaft 256, the tension for rotating the first reel 252 and the second reel 254 is offset, and the lifting rack 180 and the lower door 174 are offset. The load for moving and maintaining the door 174 to an arbitrary position can be reduced, and power saving and cost reduction can be achieved.

  Further, when attention is paid to the lower door pulley 250 in FIG. 3, it can be seen that the diameters of the winding portions of the ropes of the first reel 252 and the second reel 254 are different. With this configuration, the lift stroke ratio between the lift rack 180 and the lower door 174 can be arbitrarily set according to the use of the hanging rack 110.

In particular, in FIG. 3, the diameter of the second reel 254 around which the cable body that suspends the lower door 174 is wound is smaller than the diameter of the first reel 252 around which the cable body that suspends the lifting rack 180 is wound. Yes. The hanging cabinet 110 as shown in FIG. 3 is assumed to have a certain amount of occupying space below and not above. Therefore, elevation rack 180 but can be lowered and the height H ₁ minute, until the lower door overlaps with the top cover, i.e. only about half of the length H ₂ of the lifting rack can not be increased. The ratio of the diameter of the second reel 254 corresponding to the lower door 174 and the diameter of the first reel 252 corresponding to the lifting rack can be, for example, H ₂ / H ₁ , where H ₁ = 450 mm, H _In the case of ₂ = 200 mm, the diameter ratio may be 4/9. Thus, by making the diameter of the second reel 254 smaller than that of the first reel 252, the above-described stroke difference can be realized without using any other special mechanism.

(Interlocked with drive motor)
As described above, the lifting rack 180 moves up and down using the drive motor 190 as a power source, and the lower door moves up and down using the lifting rack 180 as an indirect power source. With this configuration, the lifting and lowering of both the lifting rack 180 and the lower door 174 can be controlled by a single power source (drive motor).

  FIG. 4 is an explanatory diagram for comparing the drive mechanism by the drive motor 190 and the drive mechanism by the lifting rack 180. Here, the mechanism for transmitting power from the drive motor 190 to the lifting rack 180 and the mechanism for transmitting power from the lifting rack 180 to the lower door 174 are independent, and the transmission direction of each power may be limited to the plane direction. it can. For example, since the mechanism for transmitting power from the drive motor 190 to the lifting rack 180 can be achieved only by turning in the YZ plane, the transmission mechanism can be realized only by a combination of a rope and a pulley. Similarly, a mechanism for transmitting power from the lifting rack 180 to the lower door 174 can be achieved only by turning by a combination of a cable body and a pulley on the ZX plane.

  With the above configuration, the lower door 174 can be pulled upward by a load when the lifting rack 180 is lowered. As described above, since the lifting rack 180 and the lower door 174 are mechanically interlocked, the driving force for lifting the lower door 174 can be provided by the driving source of the lifting rack 180. Further, since the lower door 174 is not directly receiving power from the drive motor 190, the lower door 174 also stops in conjunction when the lifting rack 180 becomes unable to be lifted due to some accident. Therefore, only the lower door 174 operates against the stop of the lifting rack 180, and secondary damage does not occur.

(Lower door guide mechanism)
Next, the guide mechanism and operation of the lower door will be described. FIG. 5 is a view for explaining the guide mechanism of the lower door.

  FIG. 5A is an exploded view for explaining the guide mechanism. Door drive fittings 176 for attaching the lower door 174 to the connecting portion 266 are respectively attached to the back surfaces of both side edges of the lower door 174. The connecting portion 266 is provided with an upper roller 268 that is an upper guided portion and a lower roller 270 that is a lower guided portion. In addition, a suspended portion 272 for attaching the second cord body 262 is provided at the upper end of the connecting portion 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.

  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. Each guide is continuous with the inclined portions 282b and 284b and the inclined portions 282b and 284b which are guided toward the front of the cabinet 170 as they go upward from the stop position (substantially the lower end position) of the upper roller 268 or the lower roller 270. And linear portions 282c and 284c for guiding 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. 5B 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 connecting portion 266, and the lower door 174 is stopped by being suspended. When the second rope 262 pulls the connecting portion 266 upward from the stop position, the lower door 174 rises while the upper roller 268 and the lower roller 270 are guided by the upper guide 282 and the lower guide 284.

  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. 5B, 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 portion 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. 5B, 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. 5 (a), the accommodation mechanism 390 is provided on the upper part of the guide metal fitting 280, and an arm 390a pivotally supported by the guide metal fitting 280 so as to be rotatable in the middle, 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 connecting portion 266 is provided with an accommodation guide 266a for the roller 390b of the accommodation mechanism 390 to travel. The accommodation 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 connecting portion 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 orthogonal to the direction of the guide groove, and thus there is no possibility of hindering the lifting 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 portion 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, the lower door wraps around the lower end of the upper door and rises along the surface, so that the feeling of pressure associated with the operation of the door can be kept to a minimum, and the usability of the kitchen lifting shelf can be improved. it can.

  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.
