Description

Detailed Description of the Invention The present invention provides a joiner for projecting corners that is fixed to projecting corners of pillars, walls, partitions, etc. to alleviate various impacts and protect the projecting corners from collisions with human bodies, objects, etc. −.

Conventionally, this type of joiner for projecting corners has a cylindrical shock absorber made of rubber or the like, a flange integrally provided at the base of the shock absorber is fixed to the wall surface, and the impact is absorbed by the elastic deformation of the shock absorber. A square bead with fitting flanges on both sides is movably fitted into a socket provided at the protruding corner using a hard elastic material such as a material that absorbs and cushions the shock, or a hard elastic material such as reinforced plastic. There are some types of sockets that can be absorbed and alleviated by movement within the socket, but in any case, the impact acts directly on the integrated flange, putting stress on the flange and socket (the attachment to the protruding corner may loosen or be easily damaged). Ta.

There is also one in which a flange on a non-slip material with shock-absorbing rubber is fitted into a horizontal groove provided on a ridge on the top surface of Kinutagi, but the Kanagutai that holds the anti-slip material has 11 bodies. Because of this, the anti-slip material tends to come off due to its own stress when it receives an impact, so the upper part of the horizontal groove is bent and overlapped on both sides of the anti-slip material to prevent it from coming off, and the hard metal concrete gets in the way and provides sufficient cushioning. I couldn't find sex.

In view of the above-mentioned prior art, the present invention provides an outward fitting groove formed between two mounting boards which are flexible and have a thick base and an L-shaped cross section. The upper receiving part protrudes outward from the fitting groove, and the lower receiving part is integrally formed with the upper receiving part which is tightly fitted into the fitting groove by sandwiching the constricted part that is locked to the protruding edge of the opening end. By providing and removably attaching the protruding corner, it is possible to effectively absorb the shock generated at the protruding corner and its vicinity, and to prevent its deformation and detachment.

The structure of the present invention will be explained based on the embodiments shown in the accompanying drawings. A pair of mounting boards 1, 1 formed in an L-shape have surfaces that are inclined from the tip to the root side, and the back side is a smooth surface, and the root side is gradually thickened. At the bottom between the base parts, the two mounting boards 1, 1 are integrally connected with a gap between them by a connecting part 2, and an outward fitting groove 3 in the shape of a disconnection arc is formed between the two mounting boards 1,1.

This fitting groove 3 has inward protruding edges 14, 14 which are narrowed at the open end side and protrude from each other to face each other.

The mounting boards 1, 1 are placed with their back surfaces against the panels 4, 4 fixed to the pillars 6 of the protruding corners 8, and nails, screws, etc. The fastener 1 is driven into the column 6 and fixed.

The hollow buffer strip 9, which is removably fitted into the outward fitting groove 3 formed between the mounting boards 1 and 1, is made of flexible material such as soft vinyl chloride resin or polyethylene resin. It is made of a material exhibiting cushioning properties, is formed into a substantially hollow shape, and extends upwardly across a constricted portion 15°15 that is engaged in a hook-like manner with the protruding edge 14.14 of the fitting groove 3. A substantially n-shaped upper receiving portion 16 is formed to protrude outward from the mounting board 1, and a substantially arc-shaped lower receiving portion 17 is formed on the lower side to be tightly fitted into the arc-shaped fitting groove 3. A hollow portion 18 communicating with the upper and lower receiving portions 16 and 17 is formed inside thereof.

Note that the mounting boards 1,1 are not connected together in advance to form an L-shape as shown in Figs. 1 and 2, but the two mounting boards 1.1 are connected horizontally as shown in Fig. 3. They can also be manufactured by connecting them in parallel in a shape and then being bent into an L shape as shown by the dotted line.

FIGS. 4 and 5 show other embodiments of the present invention. In the embodiment shown in FIG. Hook part 11.11
An abbreviated fastening piece 12 provided with is fixed to the panels 4, 4 with a fastener or adhesive, and the engaging groove 10 of the mounting board 1, 1 is fixed.
, 10, and the hook portions 11, 11 of the fastening piece 12 are fitted and locked.

In the embodiment shown in FIG. 5, a thin plate having a large number of locking claws 13 . .1 is stamped and the locking claws 13...13 are inserted into the panel 4°4 to lock it.

The present invention has the above-mentioned configuration, and includes a pair of mounting boards formed in a substantially L-shape, and an outwardly facing mounting board having protruding edges formed at the corners thereof and constricting the open end thereof. It consists of a hollow buffer strip that is removably installed in a fitting groove that is approximately arcuate in cross section, and this buffer strip has an upper part that protrudes to the outside above the constricted part that is hooked to the protruding edge in the shape of a hook. The receiving branch,
In addition, a lower receiving part is formed on the lower side of the supporting part to be tightly fitted into the above-mentioned fitting groove, and the hollow part inside thereof is continuous and communicates with each other, so that when the protruding corner receives an impact,
The upper receiving part exposed to the outside is elastically deformed due to its hollow structure and its material properties to absorb this impact, and the thick root part of the mounting board around the buffer strip and the fitting groove Permanent deformation of the upper support portion can be prevented by the elastic action of the protruding edge.

Furthermore, the upper receiving section that is tightly fitted into the insert groove and the lower receiving section that are continuous with each other absorb the pressing force from the upper receiving section to increase the shock absorption capacity of the upper receiving section, and the lower receiving section The generated reaction force is prevented from being caught by the constricted portion and the protruding edge that narrows the opening end of the fitting groove, so that the buffer strip can be prevented from detaching.

In addition, the mounting board, which is approximately L-shaped, has a thick wall at the base side and a thin wall at the tip side to form an inclined surface, and is provided in a protruding manner at the protruding corner and its vicinity. , it is possible to effectively absorb the impact force concentrated in this area, and to maintain the aesthetic appearance by preventing the appearance of discomfort with the protruding corners caused by installing the joiner.
