Description

  The present invention relates to a drawer structure that prevents a problem such as deformation of a mirror plate from occurring even when a large load is applied by a stored item.

  In general, drawers for storing clothes, etc., or drawers for learning desks for storing stationery, etc., are easy to provide a means for increasing structural rigidity because the stored items are lightweight, and a method of screwing a reinforcing tool Are often employed (for example, Patent Document 1).

  However, in the drawers S1 and S2 for storing tableware in the cabinet set S or the system kitchen as shown in FIG. 6, great consideration is required for the structural rigidity, and the drawer itself must not be deformed. Don't be.

  The drawer S1 of the cabinet S is configured to allow the inside to be seen through, and the drawer S2 is configured to allow outside air to circulate, but the basic configuration is common, and the exploded perspective view illustrated in FIG. The outline of the configuration will be described below.

  In the figure, reference numeral 1 is a bottom plate, its rear end 1b is fitted and supported in a dovetail groove 2a of a back plate 2, and side ends 1c and 1d are fitted in dovetail grooves 3a and 4a of side plates 3 and 4, respectively. It is supported together. The back plate 2 and the side plates 3 and 4 are doweled and connected at their ends. In addition, the sliders 5 of the slide unit are attached to the side plates 3 and 4, respectively, so that the drawer main body can move forward and backward.

Reference numeral 6 denotes an end plate, and upper and lower horizontal rods 6a and 6b and left and right vertical rods 6c and 6d are assembled, and a cover plate 7 such as a see-through plate, a punching metal, and a decorative panel is disposed in the frame. Then, the vertical rods 6c and 6d and the side plates 3 and 4 are combined with a dowel and integrated to complete the form as a drawer. However, in this state, since the front end 1a of the bottom plate 1 is in a floating state, it is screwed and fixed to the L-shaped metal fitting 8 attached to the center of the horizontal bar 6b with a screw 9.
JP 2000-23769

  The sectional structure of the conventional drawer constructed as described above is in the state shown in FIG. 8, and the front end 1 a of the bottom plate 1 is supported by the horizontal bar 6 b via the L-shaped metal fitting 8. In such a configuration, when a heavy object W such as ceramics is accommodated therein, and the load becomes large, there is a problem that the horizontal bar 6b is bent downward from the center as shown in FIG.

  In such a state, as shown in FIG. 10, there is a problem in that the curved reed 6b interferes with and contacts the lower reed 6a. In addition, since downward stress is continuously applied to the horizontal bar 6b, the braided portion formed by both ends of the horizontal bar 6b and the lower ends of the vertical bar 6c and 6d may be disassembled, and a gap may be generated in the end portion. .

  Furthermore, in a cabinet set S or system kitchen that is configured based on a straight line, if a curve occurs in a part, the balance of the overall design is lost and the aesthetics are lost, and the commercial value is extremely reduced.

  Therefore, the present invention solves the above problems by means described below. That is, according to the first aspect of the present invention, the support metal fitting that enables the support of the bottom plate and the connection to the end plate is fixed to the lower end of the back surface of the end plate, and the locking groove formed in the front end portion of the bottom plate The bottom end of the bottom plate comes into contact with the support side of the support metal when the load applied to the bottom plate becomes a certain level or more by engaging the locking end of the support metal.

  According to a second aspect of the present invention, in the first aspect of the present invention, the end plate is a saddle set.

  According to the present invention, since the load applied to the bottom plate of the drawer can be relaxed, the downward bending of the lower end of the end plate can be prevented, and the commercial value can be maintained without breaking the design balance. it can.

  The present invention is particularly suitable in the case of configuring a drawer for storing heavy objects, and can be realized at a low cost with a minimum number of parts.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected and demonstrated to the structure same as the past.

  FIG. 1 is an exploded perspective view of the first embodiment of the present invention, and the main body of the drawer is supported by fitting the rear end 1b of the bottom plate 1 to the dovetail groove 2a of the back plate 2 in the same manner as in the conventional configuration. The side ends 1c and 1d are supported by being fitted into dovetail grooves 3a and 4a of the side plates 3 and 4, respectively. The back plate 2 and the side plates 3 and 4 are doweled and connected at their ends. In addition, the sliders 5 of the slide unit are attached to the side plates 3 and 4, respectively, so that the drawer main body can move forward and backward.

  The end plate 6 is composed of upper and lower horizontal rods 6a and 6b and left and right vertical rods 6c and 6d, and a cover plate 7 such as a see-through plate, a plate rent metal, and a decorative panel is disposed in the frame. The vertical rods 6c and 6d and the side plates 3 and 4 are combined by doweling and integrated to form a drawer.

  Next, a support fitting 10 having a shape as shown in FIG. 2 is used for supporting the front end 1 a of the bottom plate 1. The support fitting 10 contacts a fixed end 10 a for screwing to the horizontal ridge 6 b with a screw 11, a locking end 10 b that engages with a locking groove 1 e formed on the bottom surface of the bottom plate 1, and a bottom surface of the bottom plate 1. The bearing side 10c is formed in an angle shape.

  The mounting of the support bracket 10 on the horizontal bar 6b is optional between the bottom surface of the bottom plate 1 and the support side 10c of the support bracket 10 when the bottom plate 1 is not loaded as shown in FIG. The gap G1 defined in (1) is formed. At this time, by engaging the locking end 10b of the support fitting 10 and the locking groove 1e as shown in the figure, the bottom plate 1 and the horizontal bar 6b are connected to each other. When the operation is performed, it is possible to prevent a gap from being generated between the abutting surfaces of the front end 1a of the bottom plate 1 and the horizontal bar 6b.

  In the drawer structure of the present invention thus completed, when a heavy object is stored, a load F1 is applied to the bottom plate 1 as shown in FIG. 3B, and in particular, the front end 1a of the bottom plate 1 is in a steady state indicated by a virtual line. Come down from the position. When the stored items further increase and the increased load F2 is applied to the bottom plate, the bottom surface of the front end 1a of the bottom plate 1 comes into contact with the support side 10c of the support fitting 10 as shown in FIG. In addition, you may make it the top part of the latching end 10b of the support bracket 10 contact the bottom part of the latching groove 1e simultaneously at this time.

  Thus, the increase in load due to the stored items in the process from FIG. 3 (A) to FIG. 3 (C) is absorbed by the bending deformation of the bottom plate 1 and does not affect the horizontal rib 6b. 3C, when the load further increases, the load corresponding to the increased amount affects the horizontal bar 6b. When the bottom plate 1 becomes the state shown in FIG. 3C, the rigidity of the bottom plate 1 is determined so that the load 6b can be prevented from being affected at all by the load.

  The second embodiment of the present invention is adapted to cope with a case where the mounting space of the support metal fitting 10 is narrow and there is no allowance. As shown in FIG. 4, the front end of the locking groove 1e is cut away to form a step portion 1f. To form. As a result, as shown in FIG. 5 (A), the mounting position of the support fitting 10 can be increased, so that the present invention can be carried out even when there is no margin at the lower end portion of the horizontal bar 6b. Also in the case of the second embodiment, the support bracket 10 functions in the same manner as the first embodiment as shown in FIGS. 5B to 5C, so that the intended purpose can be achieved. it can.
