Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is designed to connect a plurality of unit storage boxes, each having a front opening, in the same direction or in opposite directions so as to connect at least left and right. The present invention relates to the unit type storage device.

[Conventional technology]

In this type of unit type storage device, the outer surface of the side plate of the unit storage box is formed to have an uneven cross section, and the side plates of adjacent unit storage boxes are fitted to each other. When the side surfaces of the storage boxes are fitted together, the unit storage boxes can be easily positioned and the space can be effectively used.

As one example thereof, in Japanese Examined Patent Publication No. 50-23347, when the left and right side plates of the unit storage box are formed in a concavo-convex shape in a plan view, the concavities and convexities of the left and right side plates are formed symmetrically and the concavo-convex pattern is formed in the front-rear direction by one pitch. It is described that by manufacturing two types of unit storage boxes that are displaced by each other, the unit storage boxes can be connected to the left and right with both front and rear surfaces aligned.

However, in this configuration, since two types of unit storage boxes have to be manufactured, not only the manufacturing cost increases, but also the postures of the unit storage boxes must be checked one by one and superposed, which makes the connection work troublesome. There is a problem.

On the other hand, in Japanese Unexamined Patent Publication No. 54-16267, in forming the outer peripheral surface of the four circumferences of the unit storage box in a concavo-convex shape when viewed from the front, the concavo-convex on the upper and lower sides is shifted by 1 pitch in the left-right direction, and the concavo-convex on the left and right sides is raised and lowered. By shifting by 1 pitch in each direction, 1
It is described that the unit storage boxes of different types can be arranged side by side in the vertical and horizontal directions in a state of being fitted to each other.

[Problems to be solved by the device]

By the way, when installing this type of unit-type storage device, it is not always necessary to open each unit storage box in the same direction and use it. Sometimes you want to be able to access items on both sides of the device.

However, in JP-A-54-16267, when the unit storage boxes are left-to-right overlapping so as to open in opposite directions, the convex portions and the convex portions of the side plates of the adjacent unit storage boxes overlap each other. Therefore, there is a problem in that one type of unit storage box cannot be fitted in the opposite directions.

In addition, in Japanese Utility Model Laid-Open No. 57-189442, dovetail grooves extending in the front-rear direction are formed on one of the left and right side surfaces of each unit storage box, while the other surface of the left and right side surfaces of the unit storage box is formed. Describes a unit type storage device in which an ant tenon corresponding to the dovetail groove is formed, and the dovetail and the dovetail in unit storage boxes adjacent to each other are fitted to each other. If you open the unit storage box in the opposite direction,
Since the dovetail and the dovetail and the dovetail face each other, it is not possible to connect one type of unit storage box with the front and back reversed.

An object of the present invention is to enable one type of unit storage box to be connected to the left and right regardless of whether they are opened in the same direction or in the opposite direction.

[Means for solving the problem]

Keep it in storage furniture. On the outer surface of one of the side plates in each of the unit storage boxes, at least a first concave line located closer to the back plate, a first convex line located on the front side of the first concave line in a continuous state with the first concave line, and an opening A second convex strip located closer to the portion 2a and a second concave strip located on the back side of the second convex strip in a continuous state are formed so as to extend over the entire vertical length of one side plate. On the outer surface of the other side plate of each of the unit storage boxes, at least a third ridge located closer to the back plate, and a third ridge located on the front side of the third ridge in a continuous state with the third ridge, A fourth concave strip located near the opening of the storage box and a fourth convex strip located on the back side in a state of being continuous with the fourth concave strip are formed to extend over the entire vertical length of the other side plate, ． The interval dimension from the first connecting surface where the first concave line and the first convex line are connected to the back surface of the unit storage box, and the first connecting surface where the second concave line and the second convex line are connected to the unit storage box. The distance to the opening, the distance from the third connecting surface where the third convex line and the third concave line are continuous to the back surface of the unit storage box, and the fourth connecting line where the fourth concave line and the fourth convex line are continuous. Set the distance from the surface to the opening of the unit storage box to the same size, and. At least one convex strip and concave strip are formed in both the state where the unit storage boxes are opened in the same direction and arranged side by side and the state where the unit storage boxes are opened in the opposite direction and arranged side by side. Set the front-rear width dimension so that it fits immovably in the front-rear direction. A screwing means for fastening the side plates of the stacked unit storage boxes is provided at the same height position of the both side plates and symmetrically in the longitudinal direction.

[Function and effect of device]

According to this structure, the convex strips and the concave strips formed on one side plate of the unit storage box and the convex strips and the concave strips formed on the other side plate are arranged in reverse order, and the unit storage box is Since the distance between the back of the box and the first and second connecting surfaces is the same as the distance between the opening of the unit storage box and the third and fourth connecting surfaces, the unit storage boxes that are adjacent to each other on the left and right Whether the units are opened in the same direction or in the opposite direction, the unit storage boxes that are adjacent to each other are overlapped on the left and right with the concave and convex lines of the side plates fitted to each other. be able to.
