  In the above conventional example, the work of changing the upper and lower mounting positions of the inner drawer with respect to the intermediate member is troublesome. That is, protrusions (pins 312) projecting outward are formed at the front end and rear end of the outer surface of the inner drawer, and the protrusions can be inserted into portions corresponding to the protrusions on the inner surface of the intermediate member. A plurality of stop grooves (bag narrow grooves 315) were formed vertically. Then, the operator lifts the inner drawer and inserts protrusions into one of the plurality of retaining grooves at a total of four positions on the left and right sides, respectively, so that the inner drawer is inserted into the intermediate member. It was attached to the desired height.

  In this case, since the protrusion and the stop groove can be directly visually recognized from the front at the two left and right positions on the front side, there is no particular difficulty for the operator to insert the protrusion into the stop groove. However, at the two left and right positions on the rear side, the protrusion and the stop groove are not directly visible, and it is not easy for the operator to insert the protrusion into the stop groove, which is troublesome.

  The present invention has been invented in view of the above-described conventional problems, and an object of the present invention is to provide a drawer structure that makes it easy to adjust the upper and lower mounting positions of the inner drawer.

  In order to solve the above problems, the present invention has the following configuration.

(A) is the whole perspective view which abbreviate | omitted one part structure in embodiment same as the above, (b) is a perspective view of the principal part. It is explanatory drawing at the time of pushing in the inner drawer (including an intermediate member) in the same from the front, and fixing to an intermediate member. It is explanatory drawing of the state which pushed the inner drawer (including an intermediate member) in the same as the above from the front, and was fixed to the intermediate member.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. As shown in FIG. 2, the drawer structure of this embodiment includes a housing 1, and a drawer mechanism (not shown) provided in the main drawer 2 and the inner drawer 3 that can be stored in the housing 1. . The housing 1 has an opening 10 on the front surface, and includes at least left and right side plates 12 and a top plate (not shown). The entire front surface may be open, or an opening may be formed on a part of the front plate 11. You may have. Usually, a back plate 13 and a bottom plate may be provided, but these are arbitrary configurations. Here, the front, rear, left and right are directions when the user faces the housing 1 from the direction of pulling out the drawer, and the right side in FIG. 2A is the front and the left side is the rear.

  A main drawer 2 and an inner drawer 3 are provided so that the casing 1 can be moved back and forth freely. The main drawer 2 includes a front piece 21, left and right side pieces 22, a back piece 23, and a bottom plate (not shown), and is a box-like body that opens upward, but a part of the upward opening is blocked. Alternatively, a cutout or an opening may be formed in any one of the front piece 21, the side piece 22, the back piece 23, and the bottom plate. The front piece 21 of the main drawer 2 may be provided with a decorative plate that is longer than the front piece 21, the side piece 22, and the back piece 23. In this embodiment, the front piece 21 itself is the side piece 22. The decorative plate has a longer vertical length than the back piece 23. The inner drawer 3 includes a front piece 30 (see FIG. 2B), left and right side pieces 31, a back piece 32, and a bottom plate 34 (see FIG. 2B), and is a box-like body that opens upward. However, a part of the upward opening may be blocked, or a notch or an opening may be formed in any one of the front piece 30, the side piece 31, the back piece 32, and the bottom plate 34. The drawers 2 and 3 are moved rearward through the front opening 10 and stored in the housing 1 by the drawing mechanism, and moved forward through the front opening 10 and pulled out of the housing 1. . The drawer mechanism includes a support part provided on the inner side surface of the housing 1 and a supported part provided on the drawers 2 and 3 side and supported to be movable in the front-rear direction with respect to the support part.

  Support rails for the drawers 2 and 3 are attached to the inner surfaces of the left and right side plates 12 of the housing 1 as longitudinal portions in the longitudinal direction. The inner drawer 3 is arranged so as to be positioned above the main drawer 2, and the support rail for the inner drawer 3 is provided above the support rail for the main drawer 2.

  A slide member (not shown) supported by support rails is attached to the main drawer 2 on the outer surfaces of the left and right side pieces 22 as supported parts. The slide member is slidable back and forth while being supported by the support rail. Such a support rail and a slide member constitute a drawer mechanism for the main drawer 2, and the main drawer 2 can be moved back and forth.

  The outer surface of the inner drawer 3 (in this embodiment, the outer surfaces of the left and right side pieces 31) is detachably attached to the intermediate member 8. In the intermediate member 8, a slide member supported by a support rail is attached to the outer side surface 81 (see FIG. 2) as a supported portion, and the inner drawer 3 is attached to the inner side surface 82. In the present embodiment, the intermediate member 8 has a substantially rectangular plate shape, but may have a frame shape and is not particularly limited. The attachment of the inner drawer 3 to the intermediate member 8 will be described later. The slide member is slidable back and forth while being supported by the support rail. Such a support rail and the slide member constitute a drawer mechanism for the inner drawer 3, and the inner drawer 3 can be moved back and forth.

  Various support rails and slide members are known, including those with rollers and those without rollers, and are not particularly limited. Alternatively, the drawers 2 and 3 may be provided with rail members, and the left and right side plates 12 of the housing 1 may be provided with slide members. Further, rail members may be provided on any of the drawers 2 and 3 and the left and right side plates 12 of the housing 1. Various known mechanisms can be used as the drawing mechanism, and are not particularly limited.

  If the drawers 2 and 3 are supported forward by the support rail and are pulled forward more than the position where the drawers 2 and 3 are pulled forward (the foremost possible position), they will fall off. Therefore, a front-side restricting member (not shown) that restricts the drawers 2 and 3 from moving forward from the foremost possible position is provided. As the restricting member, a so-called stopper that restricts further movement by contacting any part including the slide members of the drawers 2 and 3 and any part on the housing 1 side is mainly used. Various members are known as the regulating member and are not particularly limited. By this front-side restricting member, the position at which the drawers 2 and 3 can actually move forward (the frontmost position) is set behind the frontmost possible position. The decorative board of the main drawer 2 may function as a regulating member on the front side of the inner drawer 3.

  In addition, there is provided a rear regulating member (not shown) that regulates the rearward movement of the drawers 2 and 3 from the position where the drawers 2 and 3 are pushed backward most (the last possible position). . The rear regulating member is the same as the front regulating member, but the decorative plate or the back plate 13 of the housing 1 may function as the regulating member even if the rear regulating member is not particularly provided. . By this rear-side regulating member, the position where the drawers 2 and 3 can actually move to the rearmost position (the last position) is set in front of the last possible position. In the main drawer 2, this last position is housed in the housing 1, and the decorative board is a housing position at a predetermined position with respect to the front surface of the housing 1, and a possible space on the bottom plate in this housing position. However, it becomes a storage space in which stored items can be stored. Further, the inner drawer 3 is stored in a predetermined position in the storage space of the main drawer 2 (this is the storage position of the inner drawer 3) in a state where the main drawer 2 is positioned at the storage position.

  Hereinafter, a structure for attaching the inner drawer 3 to the intermediate member 8 will be described. As shown in FIG. 1, on the outer surface of the inner drawer 3, projections 33 having predetermined front and rear widths and upper and lower widths and projecting outward are formed at the front and rear portions. In the present embodiment, protrusions 33 each having a substantially circular cross section are formed on the front end portion and the rear end portion of the outer surface of the side pieces 31 on both the left and right sides. In addition, the shape of the projection part 33 is not circular, and may be a square, a rectangle, a polygon, or the like, and is not particularly limited.

  Each of the inner side surfaces 82 of the intermediate members 8 on both the left and right sides has a plurality of guide grooves 9 which are open inward with a vertical width larger than the vertical width of the projection 33 and whose longitudinal direction is the longitudinal direction. Lined up side by side. In the present embodiment, the guide groove 9 has a vertical width slightly larger than the diameter of the protrusion 33 and is formed in three vertically. The guide groove 9 is also opened forward, and as shown in FIG. 2B, a part or all of the forward opening is closed by a lock member 94 such as a cap so as to be opened and closed. The vertical width of the guide groove 9 may be substantially the same as the vertical width of the protrusion 33 as long as the protrusion 33 can be inserted.

  Furthermore, a stop groove 91 that communicates with the guide groove 9 and a communication groove 92 that communicates vertically between the plurality of guide grooves 9 are provided on the inner side surface 82 of the intermediate member 8. The stop groove 91 is formed so as to communicate with the guide groove 9 downward from the rear end portion of each guide groove 9. The front-rear width of the stop groove 91 is formed to be larger than the front-rear width of the protrusion 33 so that the protrusion 33 can be inserted. In this embodiment, the front-rear width is slightly larger than the diameter of the protrusion 33. ing. The front-rear width of the stop groove 91 may be substantially the same as the front-rear width of the protrusion 33 as long as the protrusion 33 can be inserted.

  The communication groove 92 has a front-rear width that is larger than the front-rear width of the protrusion 33, and is formed to communicate vertically with the plurality of guide grooves 9 on the front side of the stop groove 91. In the front-rear position where the communication groove 92 is provided, the distance from the front end of the guide groove 9 to the communication groove 92 is shorter than the distance from the protrusion 33 at the front end of the inner drawer 3 to the protrusion 33 at the rear end. Formed as follows. As a result, as shown in FIG. 1, the protrusion 33 provided at the front end of the inner drawer 3 is formed in the guide groove while the protrusion 33 provided at the rear end of the inner drawer 3 is positioned in the communication groove 92. It is located in front of 9 and can be moved up and down.

  The attachment of the inner drawer 3 to the intermediate member 8 will be described. As shown in FIG. 3, the operator lifts the inner drawer 3 and enters the guide groove 9 at a desired height (the lowest in FIG. 3) of the intermediate member 8 at the rear end of the inner drawer 3 from the front. The protrusion 33 is inserted and placed on the lower surface of the guide groove 9. Thereafter, the operator moves the inner drawer 3 backward while holding the front portion of the inner drawer 3. Then, the projection 33 at the rear end of the inner drawer 3 passes over the communication groove 92 and is dropped into the stop groove 91 as shown in FIG. 4, and the projection 33 at the front end of the inner drawer 3 is guided into the guide groove 9. It is placed on the lower surface. Then, the lock member 94 is mounted, and the projection 33 at the front end of the inner drawer 3 is restricted from moving forward by the lock member 94, and the attachment of the inner drawer 3 to the intermediate member 8 is completed.

  Here, the operator lifts not only the front part of the inner drawer 3 but also the rear part or the whole of the inner drawer 3 when the projection 33 at the rear end exceeds the communication groove 92. When the inner drawer 3 moves backward at a predetermined speed or higher, the operator may not lift the rear part or the whole of the inner drawer 3 and the projecting portion 33 may exceed the communication groove 92.

  In this case, it is preferable that an inclined surface 93 positioned rearward is formed in the portion communicating with the guide groove 9 at the upper end of the inner surface of the rear side of the communication groove 92 as it goes upward. In this embodiment, the inclined surface 93 is formed. Chamfered (R-shaped) processing is applied. In the case where the inner drawer 3 moves rearward at a predetermined speed or higher without the rear part or the whole of the inner drawer 3 being lifted, and the projection 33 at the rear end is going to exceed the communication groove 92, the guide groove 9 There is no support of the protrusion 33 by the lower surface, and the rear part (and the protrusion 33) of the inner drawer 3 slightly falls due to gravity. However, since the inclined surface 93 is formed, it can be prevented that the inclined surface 93 rides on the inclined surface 93 and falls into the communication groove 92, and the stop groove 91 can be reached.

  In order to change the mounting height of the inner drawer 3 to the intermediate member 8, the operator lifts the rear part of the inner drawer 3 and lifts the protrusion 33 at the rear end part from the stop groove 91 and moves it slightly forward. Then, the protrusion 33 is moved to the position of the communication groove 92. Further, the projection 33 at the front end of the inner drawer 3 is pulled out forward of the guide groove 9. In this state, the operator further raises or lowers the inner drawer 3 to align the protrusion 33 with the guide groove 9 having a desired height, pushes the inner drawer 3 rearward, and pushes the protrusion 33 at the rear end. The guide groove 9 is dropped into the stop groove 91 at the rear end, and the projection 33 at the front end is inserted into the guide groove 9 from the front and placed on the lower surface.

  In the above-described drawer structure, when attaching the inner drawer 3 to the intermediate member 8, the operator inserts the protrusion 33 at the rear end of the inner drawer 3 from the front into the guide groove 9 and places it on the lower surface of the guide groove 9. If it mounts, it is not necessary to lift the rear-end part of the inner drawer 3 after that. Therefore, the operator does not need to lift the entire inner drawer 3 as in the conventional example in which the guide groove 9 is not provided, and the workability is improved.

  In the above-described drawer structure, the guide groove 9 is provided, but when changing the mounting height of the inner drawer 3 to the intermediate member 8, the operator can use the protrusion 33 at the rear end of the inner drawer 3. May not be pulled out to the front of the guide groove 9. That is, since the communication groove 92 is formed, the operator only has to pull out the protruding portion 33 at the rear end of the inner drawer 3 to the communication groove 92, which also improves workability.
