Description

  The present invention relates to an elevating-type hanging cabinet that allows an elevating rack that is a storage portion to be moved up and down smoothly and that allows storage items to be stably taken in and out from the elevating rack, and a system kitchen including the same.

  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. For example, the lifting cabinet can be moved up and down (e.g., Patent Document 1), or the door placed on the front of the hanging cabinet is opened, and the storage shelf installed in the hanging cabinet is supported by a rotating arm. There are those that are pulled down toward the front side (for example, Patent Document 2), cabinets, and those that have a lifting rack that can be moved up and down 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 protrudes and descends toward a cook, there exists a problem that it disturbs cooking work. 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.

  Furthermore, in recent years, it has been proposed to use a hanging cupboard not only for storage but also for other purposes. Patent Document 4 describes a configuration in which an elevating-type hanging cabinet is provided with a drying function or is partitioned by a partition plate to have both a storage function and a drying function.

On the other hand, in a conventional lifting / lowering hanging cabinet, a rail mechanism is provided on the inner side of both side plates of the cabinet so that the lifting rack can be moved up and down smoothly.
Japanese Patent Laid-Open No. 11-46886 JP 2004-222886 A JP 2006-000677 A JP 2004-298424 A

  The conventional rail mechanism of the cabinet is a fixed rail with no play in the front / rear / left / right direction other than the movable direction (vertical direction), or a loose-fitting rail with play only in the left / right direction when the liftable cabinet is viewed from the front. Either rail mechanism was applied to both left and right.

  In the configuration in which the fixed rails are provided inside the both side plates of the cabinet, when the lifting rack moves up and down with respect to the cabinet, the lifting rack does not swing and moves up and down smoothly. Further, since there is no horizontal swing, the user can take in and out the stored items from the lifting rack with a sense of stability.

  However, the lifting racks and cabinets that store the lifting racks are large pieces of furniture and are formed by combining multiple members. Therefore, even if they are properly manufactured, there is a limit to dimensional accuracy and some distortion may occur. There is. In addition, distortion may occur due to changes over time, changes due to temperature and humidity, or distortion of the installation surface.

  If the lifting rack or cabinet is distorted due to the above-mentioned reasons, in the configuration in which the fixed rails are provided on both side plates of the cabinet, there is no play in the fixed rail to absorb the distortion. It will be lost, and it will give a burden to the drive mechanism which performs the raising / lowering operation | movement, and it may become impossible to raise / lower in an extreme case.

  On the other hand, in the configuration provided with loose fitting rails on both side plates of the cabinet, even if the lifting rack or the cabinet is distorted due to the above reasons, there is play in the left and right direction, so the lifting rack can be lifted and lowered. Smoothness is not impaired.

  However, since the loose rail has play in the left and right direction, when the lifting rack is raised and lowered with respect to the cabinet, it swings in the left and right direction when the lifting rack is viewed from the front, or from the lifting rack. Even when the stored items are taken in and out, the left and right directions are swung, so it is undeniable that the user feels unstable.

  Accordingly, the present invention has been made in view of the above-described problems of the conventional rail mechanism, and by appropriately combining the rail mechanisms, even if distortion occurs, the present invention smoothly moves up and down and puts in and out the stored items. It is an object of the present invention to provide an elevating type hanging cabinet provided with an elevating rack that can maintain stability at the time.

In order to solve the above-described problems, a typical structure of a lifting / lowering cabinet according to the present invention includes a cabinet whose bottom surface and front surface are open, a door disposed on the front surface of the cabinet, and lifting and lowering with respect to the cabinet. A lifting rack that is supported above and installed on the upper side of the kitchen, and further provided with a substantially vertical fixed rail provided on one side plate of the cabinet and on the other side plate of the cabinet. And a driving mechanism that moves the lifting rack up and down, and an operation unit that receives an input from the user to operate the driving mechanism, and the fixed rail is one side surface of the lifting rack. fixed traveling body provided, is substantially immovably traveling in the longitudinal and lateral directions, loosely rail, Yu of one roller provided on the other side of the lifting rack The running body, lateral direction is freely movable traveling, the operation unit is a lower bottom plate of the lifting rack is disposed near the side plate fixed traveling body is provided, characterized in Rukoto.

  A fixed rail is provided inside one side of the cabinet, and the fixed rail is configured to travel by fixing a fixed traveling body provided on the lifting rack in the left-right direction, so that the lifting rack does not swing with respect to the cabinet. It can move up and down smoothly. Further, since the fixed traveling body does not operate (no play) other than the movable direction (substantially vertical direction), there is no possibility of swinging in the left-right direction. For this reason, the user can take in and out the stored items from the lifting rack with a sense of stability.

  Here, the front-rear direction refers to the direction in which the door of the liftable hanging cabinet is installed, and the depth direction is the front-rear direction. Moreover, the left-right direction means the left-right direction when the elevating type hanging cabinet is viewed from the front. Further, the transverse direction of the elevating type hanging cabinet can be rephrased as the front-rear direction and the longitudinal direction of the transverse section as the left-right direction.

  In addition, due to the configuration in which loose rails are provided on the side plates that face the side plates provided with the fixed rails, the floating traveling body that travels on the loose rails can move in the left-right direction even when the lifting-type hanging cabinet is distorted. Since there is play (there is play), the distortion is absorbed in the play in the left-right direction and the smoothness of the lifting operation of the lifting rack is not impaired.

Moreover, cupboards suspended liftable according to the present invention as described above includes a drive mechanism for elevating the elevating rack, and a manipulation unit for accepting input from a user to operate the drive mechanism, the operation unit, the lifting a lower rack of the bottom plate, the fixed traveling body is disposed in the vicinity of the side plate provided.

  With the above lifting rack drive mechanism, the user can easily lift and lower the lifting rack simply by operating the operation section. In addition, the operation rail is provided below the bottom plate of the lifting rack and in the vicinity of the side plate on which the fixed traveling body is provided, so that the fixed rail fixes the fixed traveling body provided on the lifting rack in the front-rear direction. Since it runs, the rigidity of the installation position of the operation unit can be maintained. Therefore, the lifting rack does not swing in the front-rear direction due to the user's operation, and the user can operate with peace of mind.

  Moreover, the fixed traveling body may be fitted to the fixed rail by a plurality of bearings. As a result, play in the front / rear and left / right directions can be reliably reduced, the elevating rack can be moved up / down while maintaining a sense of stability without swinging in the left / right direction, and the elevating rack can be moved in the front / rear direction by a user operation on the operation unit. It will not swing.

  According to the other structure of this invention, said raising / lowering type hanging cupboard was provided above the kitchen, It is characterized by the above-mentioned. Thereby, even if distortion arises, the system kitchen provided with the raising / lowering hanging cabinet which has a raising / lowering rack which can raise / lower smoothly and can hold | maintain the stability at the time of putting in / out of a stored item is provided.

  As described above, according to the elevating-type hanging cabinet of the present invention and the system kitchen provided with the same, even when distortion occurs, it is possible to smoothly ascend and descend and maintain stability when taking in and out the stored items.

  DESCRIPTION OF EMBODIMENTS Embodiments of an elevating-type hanging cabinet according to the present invention and a system kitchen provided with the same will be described with reference to the drawings. The dimensions, materials, and other specific numerical values shown in the following embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. Further, in the present specification and drawings, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

(Embodiment)
FIG. 1 is an overall view of a kitchen including an elevating hanging cabinet 100 according to an embodiment of the present invention. The elevating type hanging cabinet 100 lowers the stored items to the level of the eyes of the kitchen user so that the stored items can be taken out without opening and closing the door at a high place.

  A system kitchen 110 is installed below the liftable hanging cabinet 100 according to the present embodiment. The worktop 120 of the system kitchen 110 is composed of roughly three parts: a sink 130, a cooking space 140, and a stove 150. In the system kitchen 110, above the area extending across the width of the sink 130 and the cooking space 140, the elevating type hanging cabinet 100 is fixedly supported by the wall 500 on the back surface. On the other hand, above the stove 150, the range hood 160 is similarly fixedly supported by the wall 500 adjacent to the elevating hanging cabinet 100.

  Here, the stove 150 can use a gas heating cooker or an oil heating cooker, but may be an IH heater provided with a heat-resistant glass plate or ceramic plate on the upper surface as shown. In addition, the sink 130 forming the water circumference is integrally formed with a draining recess and a drain outlet by press molding, casting molding, injection molding, or the like using a metal such as resin or stainless steel plate as a material.

  FIG. 2 is a perspective view of the liftable hanging cabinet 100. The elevating type hanging cabinet 100 is housed in a space formed by a cabinet 170 having an open bottom surface and a front surface, a door 172 disposed on the front surface of the cabinet 170, and the cabinet 170 and the door 172. A lifting rack 190 that can be moved up and down, and an operation unit 180 that operates a drive mechanism described later. The lifting rack 190 has an open front, and can be used for taking in and out dishes and kitchen items. The lifting rack can also have a drying function in addition to the storage function.

  The cabinet 170 is fixed to the wall 500. For this reason, the cabinet 170 is fixed, and the lifting rack 190 is moved only in the vertical direction by a driving mechanism described later, as indicated by an arrow in FIG. Therefore, the movable range of the liftable hanging cabinet 100 is only in the vertical direction, and the horizontal direction always maintains a constant area. Thereby, a movable range does not spread in a horizontal direction, and even if a user puts in and out the raising / lowering rack 190 during cooking, it does not become a hindrance to cooking.

  The door 172 includes an upper door 174 and a lower door 176, which cover the items stored in the lifting rack 190 when the lifting rack 190 is stored in the cabinet 170. When the lifting rack 190 is lowered by a drive mechanism described later and appears below the cabinet 170, the lower door 176 moves upward in conjunction with this.

  Thereby, even if the upper end of the lifting rack 190 does not descend from the lower end of the cabinet 170, the open front of the lifting rack 190 appears in front of the user. Accordingly, the movable range of the lifting rack 190 can be narrowed, the lifting operation time can be shortened, and the height of the lifting rack 100 can be increased to increase the volume.

  Note that the upper door 174 does not move regardless of the lifting and lowering of the lifting rack 190. However, the upper end of the upper door 174 is hinged to the top plate of the cabinet 170, and the lower end is a free end. Therefore, by lifting the lower end, the upper door 174 can be opened upward with the upper end as an axis.

  When the lifting rack 190 is accommodated in the cabinet 170, the upper door 174 and the lower door 176 are kept flat. On the other hand, when the lifting rack 190 is lowered, the upper door 174 does not move and only the lower door 176 is raised. Groove-shaped guide grooves for guiding the lower door 176 are provided on both side surfaces of the cabinet 170, and the lower door 176 rises while avoiding the upper door 174. As a result, when the lower door 176 is raised, the upper end rises while tilting forward by about 20 mm.

  The operation unit 180 is installed below the bottom plate of the lifting rack 190 and in the vicinity of a side plate on which a fixed traveling body described later is provided. The operation unit 180 includes switches such as a keyboard, a cross key, and a joystick, and accepts user operation inputs.

  The drive mechanism for raising and lowering the lifting rack 190 will be described in detail below. FIG. 3 is a view showing a drive mechanism of the lifting rack 190 of FIG. In FIG. 3, the lower door 176 is not shown for the sake of clarity.

  First, two wide belts 202 are unwound from the left and right in the horizontal direction by the rotation of the motor 200. These belts are turned in the vertical direction by turning pulleys 210 (fixed pulleys) fixedly installed in the vicinity of both side plates of the cabinet 170, and the end portions are wound around pulleys (moving pulleys) fixed to the lifting rack 190. And fixed above the cabinet 170. Therefore, the lifting rack 190 moves up and down by the rotation of the drive motor 200.

  Thus, the user can easily raise and lower the lifting rack 190 by the drive mechanism of the lifting rack 190 only by operating the operation unit 180.

  4 is a cross-sectional view and a vertical cross-sectional view of the cabinet 170 and the lifting rack 190, and FIG. 4B is a cross-sectional view taken along line AA of FIG. 4A. In FIG. 4A, the door 172 of the cabinet 170 is not shown for clarity. The direction indicated by the arrow B in FIG. 4A indicates the front surface of the elevating-type hanging cabinet 100, and in this embodiment, the right side is the right and the left side is the left when viewed from the front of the elevating-type hanging cabinet 100.

  As shown in FIG. 4A, in the present embodiment, the fixed rail 300 is installed inside the right side plate (one side plate) of the cabinet 170, and the loose rail 400 is connected to the left side plate (the other side) of the cabinet 170. Of the side plate). A fixed traveling body 302 is provided on the right side surface (one side surface) of the lifting rack 190, and an idle traveling body 402 is provided on the left side surface (the other side surface) of the lifting rack 190. That is, the fixed traveling body 302 corresponds to the fixed rail 300, and the idle traveling body 402 corresponds to the loosely fitting rail 400. In the present embodiment, two idle traveling bodies 402 are installed, but the present invention is not limited to this, and one or more may be installed.

  In this embodiment, the fixed traveling body 302 and the idle traveling body 402 use traveling bodies having different mechanisms, but may be the same traveling body. In that case, by making the width of the rails different, that is, the width of one rail can be made substantially the same as the thickness of the traveling body, the fixed rail 300 can be obtained, and the width of the other rail can be made wider than the thickness of the traveling body. Play can be provided to provide a loose rail 400. Further, even if the width of the fixed rail 300 and the loose fitting rail 400 is the same, the thickness of the traveling body is made different. That is, the width of one traveling body is made substantially the same as the thickness of the rail, and the fixed traveling body 302 is formed. It is possible to provide play by making the width of the other traveling body smaller than the thickness of the rail, so that the floating traveling body 402 can be obtained.

  As shown in FIG. 4A, the idle running body 402 is a roller, and the loosely fitting rail 400 is a frame-like member (ribs with the upper edge folded back) for guiding the roller. Accordingly, the idle running body 402 is basically moved in the vertical direction, and also has a predetermined amount (amount that the roller can move within the height of the folded back of the rib) in the left-right direction (roller axial direction: C direction in the figure). Is swingable. That is, the idle running body 402 can swing in the left-right direction and has a certain amount of play.

  As shown in FIG. 4B, the fixed rail 300 and the loosely fitting rail 400 are installed on the side plate of the cabinet 170 in a substantially vertical direction, and guide the lifting operation of the lifting rack 190.

  FIG. 5 is a diagram for explaining the fixed rail 300 and the fixed traveling body 302, and the loose fitting rail 400 and the idle traveling body 402.

  As shown in FIG. 5A, the fixed rail 300 includes a pair of bearing grooves arranged in the vertical direction. On the other hand, the fixed traveling body 302 includes ball bearings 304 on both sides. Can be moved in the vertical direction by fitting in the bearing groove. Accordingly, the fixed traveling body 302 can travel in the up-down direction in a substantially stationary state in the horizontal direction (front-rear left-right direction) (arrow direction in the figure). As a result, play in the left-right direction is reliably reduced, and the lifting rack 190 can be lifted and lowered while maintaining a sense of stability without swinging.

  Moreover, since play in the front-rear direction is reliably reduced, there is no possibility of swinging in the front-rear direction. For this reason, the user can take in and out the stored items from the lifting rack 190 with a sense of stability.

  Further, as shown by a dotted line in FIG. 4B, the operation unit 180 is provided below the bottom plate of the lifting rack 190 and in the vicinity of the side plate on which the fixed traveling body 302 is provided. Thereby, even if the user presses the button when operating the operation unit 180, the lifting rack 190 does not swing back and forth, and the user can operate stably.

  In the present embodiment, the fixed traveling body 302 includes a plurality of bearings that are fitted to the fixed rail 300, and the ball bearing 304 is used as the bearing. However, the present invention is not limited to this, and a tapered bearing or the like is also suitable. Can be used.

  On the other hand, as shown in FIG. 5B, the idle traveling body 402 can swing in the left-right direction (roller axial direction: D direction in the figure) while basically moving in the vertical direction (arrow direction in the figure). There is a certain amount of play.

  Here, the cabinet 170 may be distorted due to the degree of assembly at the time of installation, distortion of the installation surface, the temperature and humidity environment of the installation location, warpage of the cabinet 170 after installation, and the like. Assuming that both the left and right rails are fixed rails 300, if the distortion occurs, the sliding resistance of the fixed traveling body 302 becomes extremely high, and the vertical movement of the lifting rack 190 does not function smoothly. However, as described above, the floating traveling body 402 that travels on the loose rail 400 can move in the left-right direction (there is play), and therefore, the deviation (distance) between the left and right rails is caused by the play of the loose rail 402. Absorbed. Therefore, the smoothness of the raising / lowering operation of the lifting rack 190 is not impaired.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. 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 applied to an elevating hanging cabinet and a system kitchen provided with the same.

It is a general view of the kitchen containing the raising / lowering type hanging cupboard which is embodiment of this invention. It is a perspective view of a raising / lowering type hanging cupboard. It is the figure which showed the drive mechanism of the raising / lowering rack. It is the cross-sectional view and longitudinal cross-sectional view of a cabinet and a lifting rack. It is a figure for demonstrating a fixed rail and a fixed traveling body, and a loose fitting rail and an idle traveling body.
