Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement of a guide device for a drawer of a sorting box or the like.

[Prior art]

In the conventional drawer guide device, as shown in FIG. 5, guide bars 5' are fixed horizontally to the left and right side walls 2' of a box 1', and the guide bars 5' are fixed to the side walls of the drawer 10'. A guide groove 12' corresponding to the drawer 10' is formed so that the drawer 10' can be moved in and out of the box body 1' in the front and rear directions. A hook portion 4' is provided on the guide bar 5' in contact with the side wall surface 2' of the box body 1'. This latching portion 4' has a latching surface at the rear, and a substantially triangular frame shape with an insertion surface at the front. On the other hand, a pin 14' is bored above the guide groove 12' on the side wall surface 13' of the drawer 10' at a position where it can engage with the hooking part 4'. Therefore, when drawing out the drawer 4', the pin 14' is aligned with the rear latching surface of the latching portion 4', and the drawer 4' is once latched. However, by pulling out more forcefully, the latching surface is elastically deformed and the latching with the pin 14' is released.
The drawer 10' can be removed from the box body 1'. Also, the detached drawer 10' should be placed in its guide groove 1.
2', and fit the guide bar 5' along the pin 14'.
enters along the insertion surface in front of the hook part 4',
It can be attached to the box body 1'. Since the conventional drawer guide device has the above-mentioned configuration, it was necessary to provide a wide space A' between the side wall surface 13' of the drawer 10' and the side wall surface 2' of the box body 1'. This space A' must be longer than the protruding length of the pin 14', and since the space A' is large,
When the drawer 10' is put in and taken out, it swings left and right, making it difficult to put in and take out the drawer. When the drawer oscillates in the left-right direction, the pin 14' comes into alignment with the side wall surface 2' of the box body 1', resulting in the disadvantage that the side wall surface 2' is scraped or damaged.

[Problems to be solved by the invention] This invention was devised as a result of intensive research in view of the above circumstances, and the main problems are to minimize the horizontal swing when the drawer is inserted and removed, and to keep the drawer in place. To provide a drawer guide device that does not damage the side wall surface of a box body.

[Means to solve the problem]

In order to solve the above problem, this invention fixes a guide bar having a hook on the side wall of the box, and aligns a protruding pin formed on the side wall of the drawer with the hook. In the drawer guide structure that prevents the drawer from falling out when the drawer is pulled out, (a) two shallow and deep guide grooves are provided on the side wall surface of the drawer, and (b) the first guide groove, which is deeper, is used for sliding the guide bar. (c) The shallower second guide groove is bored so that the hook part does not balance, (d) An equalizer is formed from the bottom of the second guide groove to the hook part side. We are taking technical measures to drill holes in the holes.

[Effect]

A guide bar provided on the side wall surface of the box body is slidably fitted into the first guide groove, and the drawer slides back and forth along the guide bar. Also, a second guide groove connected to this and shallower than the first guide groove is provided.
The guide groove is formed so that the hook provided on the guide bar does not balance when the drawer is moved in and out. The second guide groove is provided with an equalizer that can engage with the hooking portion of the guide bar, and engages with the hooking portion to restrain the proximal end of the drawer when the drawer is pulled out. is prevented. Since this equalizer is provided inside the second guide groove, it does not protrude from the side wall surface of the drawer. Therefore, there is no need to provide a space for the balancer between the side wall surface of the drawer and the side wall surface of the box body, and it is only necessary to set the minimum space that allows sliding.

【Example】

Hereinafter, a preferred embodiment in which the drawer guide structure according to the invention is applied to a sorting box will be described based on the drawings. The sorting box shown in Fig. 2 has a box body 1 with an opening at the front.
10 drawers stored in multiple stages above and below so that they can be drawn out
It is made up of a combination of The guide structure of this drawer is as shown in Figure 1.
A guide bar 5 fixed to the side wall surface 2 of the box body 1 and having a hook 4; and a guide groove 12 bored in the side wall surface 13 of the drawer 10 corresponding to the guide bar 5.
and a pin 14 shown as an example of an equalizer protruding from the guide groove 12. That is, in the case of this embodiment, the guide bar 5 is
As shown in the figure and Fig. 3, it is made of a rod material with a rectangular cross section, and a groove 5A for attaching the hook part 4 is bored on the outside at the front side (the side that contacts the side wall surface 2 of the box body during installation). has been done. The base of the synthetic resin hook 4 is fitted into this groove 5A, and fixed with screws or the like so that it is flush with the outer surface of the guide bar 5. This hooking portion 4 is formed with an elastic hooking portion 6 that projects upward from the guide bar 5 . This elastic latching portion 6 has a belt shape narrower than the guide bar 5, and has a latching tapered surface 6A formed on the rear side in the drawing direction B of the drawer 10, and a fitting tapered surface 6B formed on the front side. It has a roughly triangular frame shape. That is, the locking tapered surface 6A has a shape in which a locking portion 7 that gradually rises at the same slope from the top surface of the guide bar and has a steep slope near the top is connected, and the fitting tapered surface 6B that connects with the locking portion 7 is It consists of a tapered surface that gradually descends at the same slope beyond the above-mentioned top and descends to the upper surface position of the guide bar. Moreover, the above-mentioned latching tapered surface 6A and the fitting tapered surface 6
A notch 6C is provided on the inner side of each proximal end with B, so that the respective surfaces 6A and 6B are easily bent. Therefore, as shown in FIG.
When the drawer 10 is pulled out from the rear and the pin 14 moves forward in the direction B, it first aligns with the latching tapered surface 6A and is latched by the latching portion 7 (see FIG. 4a). Therefore, there is no risk that the drawer 10 will come off from the box body 1. Then, when a predetermined force or more is applied, the locking part 7 is elastically deformed and bent downward (see b in the same figure), and the pin 1
4 can pass through the top, and the drawer can be removed from the box body 1 (see c in the figure). When inserting the drawer 10, the pin 14 can pass through the top and fit into the inside of the box while gradually bending the fitting tapered surface 6b downward. In such a configuration, the guide groove 12 bored in the side wall surface 13 of the drawer 10 is connected to the guide bar 5.
It consists of two shallow and deep grooves into which the elastic hook 6 is fitted. That is, the guide groove 12, as clearly shown in FIG.
A first guide groove 12A having a deep groove wall surface so as to be in sliding contact with the outer circumferential surface of the guide bar 5, and a second guide groove 1 above which the elastic hook 6 passes.
2B, and a pin 14 is bored outward from the bottom of the second guide groove 12B. This pin 14 is inserted into the second guide groove so that its tip does not protrude outward from the side wall surface 13 of the drawer 10.
It is provided in 2B. With the above configuration, the tip of the pin 14 does not protrude outward from the side wall surface 13 of the drawer 10 and moves, so it does not balance with the side wall surface 2 of the box body 1.
This side wall surface 2 will not be damaged. Therefore, since the side wall surface 2 of the box body and the side wall surface 13 of the drawer 10 come into contact with each other, the distance A for sliding the drawer 10 can be set to the minimum. In addition, in the above embodiment, the hooking portion is formed separately from the guide bar, but the two may be formed integrally. Further, the structure of the elastic locking portion is not limited to the above-mentioned embodiment, and any structure that is configured to balance with the balancer and lock in the drawing direction is included in the technical scope of this invention. .

[Effect of the idea]

Since this invention has the above structure, the pin does not protrude outward from the side wall surface of the drawer, so even if the drawer swings from side to side within the box body, the pin will not damage the side wall surface of the box body. In addition, the gap between the side wall surface of the drawer and the side wall surface of the box body only needs to be the minimum gap that can be slid, so the drawer can be smoothly inserted and removed back and forth without swinging from side to side, making it easy to operate. Excellent.
