Description

[Detailed description of the invention] A. Purpose of the invention a. Industrial field of application The present invention relates to a shelf board joint member suitable for assembled shelves.

b. Prior art and its problems Conventionally, for example, assembly shelves used as furniture require shelf boards of a certain length, but if they are too long, it is inconvenient for assembly, transportation, storage, etc. However, if the structure is short, it takes time and effort to connect the ends of each other to form a long shelf board, and it is also difficult to make the connecting portions sturdy.

B. Structure of the invention a Means for solving the problem The present application attempts to solve the above-mentioned problem with the following structure.

That is, the thing of the present application is a joint member for a shelf board consisting of one single member 2-1 and the other single member 3-1 that is engaged with and detached from the one member single 2-1.
In this case, a thick wall portion 2H for locking is protruded from the front portion of the lower surface of the top plate 2D of the flat box-like body 2, leaving a passage 2E on the back side and insertion paths 2F, 2G on the left and right portions. Further, small protrusions 2F1 and 2G1 for guiding are protruded from the center of the surfaces corresponding to the insertion paths 2F and 2G of the left and right portions of the lower surface of the top plate 2D, and the front surface of the thick wall portion 2H for locking is provided. A horizontal insertion plate 2I is provided to project forward in the front direction, and an engagement hook piece 2I1 is provided to protrude from the bottom surface of the distal end of this horizontal insertion plate 2I, and
A groove 2I2 corresponding to the guide small protrusions 2F1 and 2G1 is carved in the center of the lower surface of the horizontal insertion plate 2I in the front-rear direction, and the single member 3-
1 is used when the single member 2-1 is used upside down, that is, in the left and right plates 4 and 5 desired to be connected, the right end surface 4 of the left plate 4 is used.
A. Fix the above-mentioned single member 2.1 with the box-like body 2 buried therein, and fix the above-mentioned single member 3-1 on the left end surface 5A of the right plate 5 with the box-like body 2 buried therein. It is configured.

b. Embodiment of the invention 1 is a joint member for a shelf board according to the present invention, which is composed of one member unit 2-1 and the other member unit 3-1 that is engaged with and detached from this one member unit 2-1.

Therefore, the single member 2-1 is constructed as follows.

2 is a flat box-shaped body, with a bottom plate 2A having a horizontally rectangular shape on the left and right sides, left and right side walls 2B and a rear side wall 2c.
A top plate 2D is stretched over the upper surfaces of the left and right side walls 2B and the rear side wall 2C, and on the front part of the lower surface of the top plate 2D, there are a passage 2E on the back side, an insertion passage 2F on the left and right parts, Thick wall part 2H for locking, leaving 2G
is installed protrudingly.

Furthermore, guide small protrusions 2F1 and 2G1 are provided protruding from the center of the lower surface of the top plate 2D on the left and right sides corresponding to the insertion paths 2F and 2G.

Locking claws 2A1 and 2D1 are provided on the outer peripheral surfaces of the bottom plate 2A and top plate 2D of the box-shaped body 2.

2I is a horizontal insertion plate protruding forward from the front face of the thick wall portion 2H for locking, 2I1 is an engagement hook protruding from the bottom surface of the tip of this horizontal insertion plate,
A groove 2I2 corresponding to the guide small protrusions 2F1 and 2G1 is cut in the center of the lower surface of the insertion horizontal plate 2I in the front-rear direction.

Reference numeral 2J denotes a thick part attached to the inside of the rear wall 2C of the box-like body 2, and a projection 2J1 having a U-shape in plan is protruded from the front center of this thick part 2J.

When the single member 2-1 and the single member 3-1 are engaged with each other as described later, this protrusion 2J1
It engages with the recess at the tip of the groove 2I2. As a result, the single member 2-1 and the single member 3-1 are temporarily locked.

The above-mentioned single member 3-1 is used in a state in which the above-mentioned single member 2-1 is upside down.

In addition, the passage 2E and the left and right insertion passages 2F,
2G has a roughly U-shaped planar structure, but now,
The above-mentioned single member 3-1 is compared to the above-mentioned single member 2-1.
In order to connect the single member 3-1, insert the engagement hook 2I1 of the member 3-1 downward from the insertion path 2G of the member 2-1 as shown by arrow A, and then insert it to the right as shown by arrow B. When moved to , the engaging hook piece 2
I1 will be located in the passage 2E.

In this state, the engaging hook piece 2I1 and the thick wall portion 2H for locking on the side of the single member 2-1 are locked with each other.

When separating both, use the above-mentioned engaging hook piece 2I1.
When moved to the left, the engagement hook piece 2I1 is located in the insertion path 2F, and when moved to the right, it is located in the insertion path 2G, so it is preferable to move it back as it is.

Therefore, as shown in FIG. 3, by preparing an appropriate number of individual members 2-1, 3-1 fixed in advance to both end surfaces of the plate 4, the plates 4 can be connected in the longitudinal direction.

c Action The plates 4 and 5 that are currently located on the left and right and which are desired to be connected
At this time, the single member 2-1 is fixed to the right end surface 4A of the left plate 4 with the box-shaped body 2 buried therein, and the single member 3-1 is fixed to the left end surface 5A of the right plate 5 as a box. The shaped body 2 is fixed in the buried state.

When the plates 4 and 5 are connected, the single member 2-1 and the single member 3-1 are engaged in the manner described above, so that the two plates are reliably joined at their end faces. become. When removing both plates, it is advisable to do so in the same manner as described above.

C. Effect of the invention Since the main proposal is structured as described above,
The plates 4 and 5, which are preconfigured to a handling length, can be connected with an extremely simple operation, and the connected portion can be made robust. In addition, no tools are required during the work, and the joints are not exposed to the outside, making it suitable for shelf boards for assembled shelves.
