Description

  The present invention relates to a lifting shelf having a box-shaped cabinet that is open on the front side and the lower side.

  2. Description of the Related Art Conventionally, as a kind of a hanging shelf installed above a kitchen, a so-called lifting shelf in which a hanging shelf body is raised and lowered is provided. There are two types of lifting shelves: manual type and electric type. As a manual type, for example, Patent Literature 1 proposes an elevating shelf including a hanging shelf body that moves up and down in a straight line.

  The cabinet in the lift shelf needs to be opened at the bottom in order for the hanging shelf body to enter and exit, and the front side surface is often opened for maintenance and the like. Then, the cabinet will open two continuous surfaces on the near side and below, and there is a risk of deformation due to load and aging. Therefore, it is preferable to increase the rigidity of the cabinet by connecting the front side lower portions of the left and right side plates of the cabinet with members.

  Patent Document 2 proposes a configuration in which front lower portions of left and right side plates of a cabinet are connected to each other by a horizontally long operation unit 8 in an electric lift shelf. That is, the operation unit also serves as a connecting member. According to Patent Document 2, smooth lifting and lowering of the hanging rack body can be realized by preventing deformation of the left and right side plates of the cabinet.

Japanese Patent No. 4801454 JP 2010-252886 A

  However, in order to unify the appearance, the hanging cabinet usually needs to be sized with the kitchen cabinet. The kitchen cabinets are lined up in several sizes (widths), and the cabinets in the lift racks are lined up in several sizes accordingly. Then, if it is set as the structure which connects and fixes the near side lower parts of a right-and-left side board with the operation unit 8 like patent document 2, you have to prepare an operation unit for every size, and there exists a problem that production cost rises. .

  Moreover, in patent document 2, the operation unit protrudes from the front door of the cabinet. This is because it is necessary to secure a space for the hanging shelf body to move up and down inside the cabinet, and as a result of combining the front door and the rear surface of the operation unit in this space, the operation unit is closer to the front door than the front door. It has been protruding. However, it is preferable in terms of design that the front surface of the cabinet is flat.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reduce production costs and improve the appearance of a lifting shelf provided with a hanging shelf body that moves up and down linearly.

  In order to solve the above-described problems, a typical structure of a lifting shelf according to the present invention is a box-shaped cabinet whose back is fixedly installed on a wall surface and at least the front side and the lower side are opened, and a vertical guide means on the cabinet. A suspension shelf body attached so as to move up and down in a straight line, and an auxiliary curtain plate hung on the front lower side of the left and right side plates of the cabinet, the auxiliary curtain plate is an end portion fixed to the left and right side plates And a beam member made of an extruded product and connecting left and right end members, and the front surface of the auxiliary curtain plate is composed of left and right end members and beam members.

  According to the above configuration, even if several types of sizes are lined up in the cabinet, the left and right end members are common parts, and the central beam member only needs to cut a long extruded product. For this reason, it is not necessary to manufacture a metal mold | die for every size, and since part stock can also be reduced, production cost can be reduced.

  An LED lighting fixture may be attached to the inside of the beam member. Since the LED lighting apparatus can be configured to have a small volume, the beam member can be protruded rearward without greatly eroding the space in which the hanging shelf body moves up and down.

  Left and right arm members that can be swung up and down with an arc-shaped trajectory that is attached to the cabinet and the tip swells toward the front, and can be rotated to the arm member so that it can swing in the substantially horizontal direction on the left and right side plates of the hanging shelf body And a handle arm attached to extend downward from the swing plate, and the left and right arm members swing up and down while drawing an arcuate trajectory. It is preferable that the left and right side plates of the hanging shelf body pass through the rear side of the end member in the lifting shelf that moves up and down in a straight line.

  In the above configuration, although the hanging shelf main body moves in a vertical straight line, the tip of the arm member swings in an arcuate locus on the front side, so the rail for moving the swing plate protrudes on the front side. There is a need. However, according to the above configuration, the lighting apparatus is provided inside the beam member of the auxiliary curtain plate and not provided inside the end member, so that the auxiliary curtain plate as a whole has both ends thin and the center portion thick. Become. And since the right-and-left side board of a hanging shelf main body passes the rear side of an edge part member, even if it arrange | positions a lighting fixture inside a beam member, it does not interfere with this. Therefore, the auxiliary curtain plate can be lowered to the rear side, the space inside the cabinet can be used effectively, and the appearance can be improved.

  According to the present invention, it is possible to reduce the production cost and improve the appearance of the lifting shelf including the hanging shelf body that moves up and down linearly.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 to FIG. 3 are three-dimensional views for explaining a lifting shelf according to the present embodiment. FIG. 1 is a diagram showing a state in which a hanging shelf body is housed, and FIG. 3 is a figure which shows the state which open | released the hanging shelf main body. FIG. 4 is a side view illustrating the lifting mechanism.

  The lifting shelf 100 shown in FIG. 1 is attached to the box-shaped cabinet 110 so that the hanging shelf main body 200 moves up and down linearly. The cabinet 110 is fixedly installed on a wall surface (not shown) on the back side, and the front side and the lower side are open. A front door 120 with double doors is attached to the opening surface 112 on the front side of the cabinet 110. In FIG. 1, the right front door and the right side surface of the cabinet 110 are not shown to show the internal configuration. The opening surface 114 below the cabinet 110 remains open, and the hanging shelf body 200 moves up and down from the opening surface 114.

  Since the hanging shelf body 200 avoids a collision with an article placed on the top plate of the kitchen, it is difficult to prepare the hanging shelf body 200 having a height that uses the entire height of the cabinet. However, if it does so, a clearance gap will be made in the upper part of the elevating shelf 100. Therefore, in order to effectively use the limited kitchen space, a shelf plate 116 is provided above the uppermost position of the hanging shelf body 200 inside the lifting shelf 100. On the shelf board 116, it is convenient for storing things to be kept and things with low frequency of taking in and out, such as highly seasonal items. The hanging shelf main body 200 stores tableware that is frequently used and can be put in and out without taking time and effort to stretch the body or bring a step. Efficient use can be achieved.

  The hanging shelf main body 200 constitutes a storage space by side plates 210 and 212 arranged on the left and right sides, a bottom plate 214, and frames 216 and 218 that connect upper portions of the left and right side plates 210 and 212. A guide portion 280 extending in the vertical direction is provided behind the left and right side plates 210 and 212, and is combined with a vertical rail 282 fixed to the cabinet 110. The suspension rack body 200 moves up and down in a straight line by the upper and lower guide means including the upper and lower rails 282 and the guide portion 280.

  Next, the lifting mechanism will be described. In the present embodiment, the elevating mechanism is a parallel link mechanism that is symmetric, but in the following description, only one side will be described.

  A handle arm 220 extending in the width direction is provided below the hanging shelf body 200. The handle arm 220 is connected to the swing plate 228 via an arm attachment portion 224 and an arm portion 226. In other words, the handle arm 220 is attached by extending downward from the swing plate 228. The arm portion 226 passes outside the left and right side plates 210 and 212 and extends in the vertical direction. A substantially horizontal rail 230 is formed on the upper outer side of the left and right side plates 210 and 212, and the swing plate 228 extends along the rail 230 on the outer wall surface of the left and right side plates 210 and 212 of the suspension rack body 200 in a substantially horizontal direction. It is attached so that it can swing.

  As clearly shown in FIGS. 2 and 4B, the swing plate 228 is connected to the first arm member 232. The first arm member 232 is attached to an attachment member 130 fixed to the cabinet 110 by a shaft 232a at the end opposite to the swing plate 228, and draws an arcuate trajectory in which the tip portion bulges forward. It can swing. From the above configuration, when the handle arm 220 is moved in the front-rear direction, the swinging plate 228 moves in the front-rear direction, and accordingly, the first arm member 232 swings up and down while drawing an arcuate trajectory. 200 can be moved up and down linearly.

  As shown in FIG. 4, the mounting member 130 is provided with two dampers 240 and 242 that relieve the impact in the near side direction and the far side direction. A second arm member 234 is attached to the movers of the two dampers 240 and 242, and the second arm member 234 is connected to the first arm member 232 by a third arm member 236. Accordingly, when the first arm member 232 is at the upper swing end, the damper 240 operates (see FIG. 4A), and when the first arm member 232 is at the lower swing end, the damper 242 operates. (See FIG. 4C), the impact and noise at the moving end of the hanging shelf body 200 can be reduced.

  In addition, a spiral spring 244 is accommodated in the attachment member 130 and is connected to the first arm member 232 via the fourth arm member 246 and the fifth arm member 248, and is attached in a direction to push the first arm member 232 upward. It is fast. Thereby, the load on the hanging shelf main body 200 and the stored items can be reduced, and the operation when the user stores the hanging shelf main body 200 can be assisted. As an assist function, as shown in FIG. 3, a tension spring 250 that connects the cabinet 110 and the hanging shelf body 200 is also provided.

  As shown in FIG. 4B, a catch member 254 is provided inside the arm attachment portion 224 of the handle arm 220. On the other hand, a groove 256 for passing the catch member 254 in a substantially horizontal direction is formed in the lower outer wall surface of the left and right side plates 210 and 212. A hook-shaped keeper 258 that engages with the catch member 254 is provided at the end on the far side of the groove 256. The catch member 254 and the keeper 258 constitute a lock unit for the handle arm 220.

  As a result, as shown in FIGS. 4A and 4C, when the hanging shelf main body 200 is at the upper and lower moving ends, the catch member 254 and the keeper 258 are engaged, and the movement of the handle arm 220 is locked. As shown in FIG. 4 (b), while the hanging shelf main body 200 is moved, the catch member 254 and the keeper 258 are separated from each other, so that the movement is not hindered. Thus, by locking the movement of the handle arm 220 at the moving end of the hanging shelf main body 200, the swing of the first arm member 232 can be locked and the posture of the hanging shelf main body 200 can be maintained. Therefore, the stability of the posture of the hanging shelf main body 200 at the upper and lower ends can be improved.

  Further, as shown in FIG. 4A, the first arm member 232 can swing to the back side by an angle α from the upper side in the vertical direction. Similarly, in the downward direction, it can be swung to the far side by an angle β from the vertically downward direction. α and β are preferably about 3 degrees, for example. Thereby, when holding the posture of the hanging shelf body 200, not only the locking force of the locking means but also the gravity can be used in the upper part, and the biasing force of the assist function can be used in the lower part. The posture can be held more reliably.

  5 and 7 are diagrams for explaining the auxiliary curtain plate of the cabinet. As shown in FIG. 5A, an auxiliary curtain plate 290 is stretched over the lower portions on the near side of the left and right outer walls 132 and 134 of the cabinet 110. The auxiliary curtain plate 290 includes end members 292 and 294 that are fixed to the left and right outer walls 132 and 134, and a beam member 296 that connects the left and right end members 292 and 294. The front surface of the auxiliary curtain plate 290 is composed of left and right end members 292 and 294 and a beam member 296. In other words, the end members 292 and 294 also have a certain width, and are observed from the front when the front door 120 is opened.

  The end members 292 and 294 are thin metal plate members. FIG. 6 is a diagram illustrating the end member. 6A and 6B are views of the left end member 292 viewed from the back side. The end member 292 includes a front plate 292a that constitutes a part of the front surface of the auxiliary curtain plate 290, a fixing portion 292b that fixes the end surface of the beam member 296, and a wall fixing portion 292c that is fixed to the side plate 132 of the lifting shelf 100. It has a U shape overall. Since the front plate 292a is substantially flush with the front surface of the beam member 296, a space having a thickness in the depth direction of the beam member 296 is formed behind the end member 292. The fixing portion 292b is provided with a hole 292d through which the wiring of the lighting fixture is passed.

  6C and 6D are views of the right end member 294 viewed from the back side. Similarly to the end member 292, the end member 294 is fixed to the front plate 294 a constituting a part of the front surface of the auxiliary curtain plate 290, the fixing portion 294 b that fixes the end surface of the beam member 296, and the side plate 134 of the lifting shelf 100. The wall fixing portion 294c is formed and has a U-shape as a whole. Therefore, a space corresponding to the thickness of the beam member 296 in the depth direction is also formed behind the end member 294. Further, a power supply unit 295 and wiring covers 295a and 295b for supplying power to the lighting fixture are connected to the wall fixing portion 294c.

  The beam member 296 is made of an aluminum alloy extruded product, and has a thickness in the depth direction. As a result, the rigidity is increased and the left and right outer walls 132 and 134 are fixed.

  As shown in FIG. 5B, the beam member 296 includes a beam body 296a and an upper cover 296b. By forming the beam member 296 as an extruded product in this way, the left and right end members 292 and 294 are common parts and the central beam member 296 is long even if several types of sizes are lined up in the cabinet 110. What is necessary is just to cut an extruded product of a scale. For this reason, it is not necessary to manufacture a metal mold | die for every size, and since part stock can also be reduced, production cost can be reduced.

  Further, as shown in FIGS. 5B and 7A, an LED lighting apparatus is attached to the inside of the beam member. Here, the end members 292 and 294 and the beam member 296 all have the front surface substantially coincident with the front surfaces of the outer walls 132 and 134, and the beam member 296 protrudes rearward from the end members 292 and 294. ing. However, since the LED lighting apparatus can be configured to have a small volume, the beam member 296 can be protruded backward without greatly eroding the space in which the hanging shelf body 200 moves up and down.

  Further, as shown in FIGS. 5A and 7B, the left and right side plates 210 and 212 of the hanging shelf body 200 pass through the rear side of the end members 292 and 294. In the elevating shelf 100 according to the present embodiment, the suspension shelf body 200 moves in a straight line, but the tip of the first arm member 232 swings in an arcuate locus on the front side, so the swing plate 228 is moved. The rail 230 to be made needs to protrude to the near side. In other words, the depth of the side plates 210 and 212 of the suspension rack body 200 is determined by the vertical movement amount (stroke) of the suspension rack body 200, and it is difficult to reduce the depth. On the other hand, there is a demand for reducing the overall depth of the lifting shelf 100.

  Therefore, according to the above configuration, the lighting device is provided inside the beam member 296 of the auxiliary curtain plate 290 and not provided inside the end members 292 and 294, so that both ends of the auxiliary curtain plate as a whole are thin. The part is thick. Since the left and right side plates 210 and 212 of the hanging shelf main body pass through the rear side of the end members 292 and 294, even if a lighting fixture is arranged inside the beam member 296, it does not interfere with this. Therefore, the auxiliary curtain plate 290 can be lowered to the rear side (biting inward), the space inside the cabinet 110 can be used effectively, and the appearance can be improved.

  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.
