Description

[Detailed explanation of the idea] The present invention relates to a wall panel connector.

Conventionally, bolts have been used to connect multiple wall panels in storage rooms, lockers, bookshelves, etc. made of metal plates, but corresponding nuts and female threads are required, which takes a lot of time to assemble, and the back Two-point connections, such as between wall panels or rear wall panels and side wall panels, can be easily tightened with bolts, but when connecting three points, such as between rear wall panels and partition wall panels, bolts can be used. Not only does it require a large number of bolts, but it is also difficult to tighten the bolts to meet the requirements, as dimensional deviations will occur if the three points are not tightened at the same time.

This invention was made to solve these problems, and it can be used not only to connect rear wall panels together, or to connect rear wall panels to side wall panels, but also to connect rear wall panels to each other without using bolts or the like. It is an object of the present invention to provide a wall panel connector that can connect three points of a partition wall panel at the same time.

The present invention will be explained below based on the drawings.

First, to explain the structure, as shown in Figure 1, a thin rectangular box is formed from a metal plate, and a pair of band-shaped plates of a predetermined width are protruded forward from both sides of the box by extensions of the same plate surface. Hook-shaped protrusions 1a and la are formed, and first and second press-contact parts 1c and 1b are formed at the opening edge of the box.

The hook-shaped protruding piece 1a has its upper edge curved downward in an arc shape, its lower edge curved upward in a semicircular shape, and then its tip edge is bent into a U-shape, and a jaw is formed on the inner surface. Part 1e
is formed.

Incidentally, the gap between each of the pressure contact parts lc, ld and the jaw part 1e is formed to be narrower than the thickness of the plates to be clamped.

Furthermore, the side plate of the case is cut out to form a jaw portion 1 on the hook-shaped protrusion piece 1a.
Mounting grooves 1b and ld are recessed at opposite positions of e to constitute a wall panel connector 1.

On the other hand, as shown in part A of FIG. 2, on the front vertical surfaces of the left and right rear wall panels 3A and 3B, which are three-point jointed, as shown in FIG. A wide hole is formed slightly inwardly than the thickness of the plate to match the hook-shaped protrusions 1a, and the width gradually decreases outward from the middle to the bottom, making it possible to fit the hook-shaped protrusions 1a in close contact. symmetrical tapered elongated holes 3e and 3f are provided respectively,
Parallel elongated holes 2a are provided at the same position on the front vertical surface of the partition wall panel 2 from the top to the bottom into which both hook-shaped protrusions 1a of the connector 1 can be inserted.

Next, as shown in Figure 2, the left and right rear wall panels 3A.

3B and the partition wall panel 2 are connected at three points, the left and right rear wall panels 3A and 3B are placed inside the partition wall panel 2 whose ends are U-shaped, with both ends touching each other. When the hook-shaped protruding piece 1a of the connector 1 is inserted into the front and rear elongated holes 2a, 3e, and 3f that are aligned with each other, and the connector 1 is pressed downward and slid as shown in FIG. 5, as shown in FIG. As clearly shown in , since each of the tapered elongated holes 3e and 3f is formed to be narrower in the outward direction, the elongated holes 3e and 3f are moved toward the center by the descent of the hook-shaped protrusion 1a. The rear wall panels 3A and 3B can be closely connected.

In addition, first and second press-contact parts 1c and 1d formed on the edge of the box of the connector 1 are brought into contact with the joint surface of the partition wall panel 2, while each hook-shaped protrusion 1a has a tapered elongated hole. 3e, 3f and slide, the jaws 1e of the projecting pieces press and deform the elongated hole edges from the back side, so that both the back wall panels 3A, 3B and the partition wall panel 2 are clamped at the same time. It can be strongly bonded.

In this way, the connector 1 of the present invention can easily and reliably connect the three points as described above, and as shown in section B of FIG. Two-point connections can also be made easily and reliably.

In this case, although it is not clearly shown in the drawings, the end of the side wall panel 4A is shaped like the end of one of the rear wall panels 3A and the end of the partition wall panel 2, and the air space is After fitting the back wall panel 3A formed in the same way as the end of the other back wall panel 3B, insert the hook-shaped protrusions of the connector 1 into the same tapered elongated holes 3e and 3f provided on both sides. By inserting 1a and pushing down, a two-point connection can be easily and reliably made.

The rear wall panel 3B and side wall panel 4B on the opposite side can also be easily and reliably joined at two points in the same manner as described above.

Of course, the front wall panel and each side wall panel 4A mentioned above.
, 4B, the purpose can be achieved by the two-point connection described above.

As explained above, in the present invention, a pair of hook-shaped protrusions 1a, la are provided on the connector 1, and the hook-shaped protrusions 1a are inserted into the long holes 2a bored at each end of a plurality of wall panels to be connected. When inserted and pressed and slid, the jaw 1e formed on the inner surface of the hook-shaped protrusion 1a presses and deforms the edge of the elongated hole 2a from the back side, and the first and Second pressure contact part 1
By sandwiching each wall panel between panels c and 1d, not only can wall panels 3A and 3B and 4A and 4B be easily connected at two points, but also wall panels 3A and 3B and partition panel 2 can be connected easily. The 3-point connection can also be connected easily, securely, and at the same time without using ports, etc., so storage rooms, lockers, bookshelves, etc. can be assembled accurately and quickly without dimensional deviations, increasing the precision of the product. This has the effect of improving assembly efficiency.
