Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a non-slip device that is attached to leg members of furniture such as chairs and tables made of pipes.

Conventional Technology Conventionally, when furniture such as pipe chairs and tables is used in a gymnasium or the like, it is necessary to use an upward-facing top to prevent the furniture from slipping on the floor and to prevent damage to the floor. A non-slip device made of synthetic resin or the like is attached to the lower piece of the leg member having a letter shape.

This anti-slip device is generally installed using drainage holes provided on the lower surface of the lower left and right positions when plating the leg member, and the required conditions are that it is easy to install and operate. In addition, the non-slip device should be configured so that it does not separate from the leg member due to external force after being attached.

By the way, conventionally, a locking protrusion that locks into a drainage hole provided in a lower piece of a leg member is integrally provided at the center of the inner surface of a fitting member made of synthetic resin and having a C-shaped cross section. For example, a non-slip device made of
It is publicly known in Publication No. 142513 to Publication No. 43900/1983.

Problems to be Solved by the Invention However, in conventionally known anti-slip devices, the entirety is made of synthetic resin, so when trying to obtain sufficient strength, the structure itself becomes thick and requires a large amount of material, resulting in high costs. There was a risk that the clamping force would be insufficient.

Means for Solving the Problems Therefore, the present application has an opening into which a pipe-shaped leg member having a hole can be inserted, and an arc-shaped portion that surrounds more than half the circumference of the leg member inside. The inner surface of the main body is made of synthetic resin and has an arc-shaped cross section, with a metal plate with a cut and raised piece embedded in the center.
The leg member has a locking protrusion that locks into the hole, and a cut and raised piece is embedded in the locking protrusion. Preferably, the main body has a central portion with a thick wall. Then, the metal plate is formed to be gradually thinner toward both ends in the curved direction, and the metal plate is a steel plate in order to increase the elasticity of the metal plate.

Function: As in the past, the opening of the fitting member is pressed against the leg member from below, and while opening the opening, the fitting member is tightly fitted onto the outer periphery of the leg member, and The locking protrusion is inserted into a hole provided in the leg member and locked.

Embodiment The embodiment of the present application will be described in detail below based on the drawings. In 1, the inner circumferential surface is curved to fit the outer circumference of the lower part of the leg member 10 made of a pipe, and the outer circumferential surface is thick in the central part. The main body is made of a soft synthetic resin such as vinyl chloride or polyurethane resin, or a semi-hard synthetic resin such as polyester elastomer, and has openings 2 with the wall thickness gradually decreasing toward both ends in the curved direction. A metal plate, preferably a steel plate 3, is embedded inside by insert molding. This steel plate 3 has an arcuate portion 3a that surrounds more than half the circumference of the leg member 10, a cut and raised piece 3b is provided at the center thereof, and through holes 4 are provided at required positions. Therefore, the inner layer and outer layer of the main body 1 with the steel plate 2 as a boundary are integrally connected via the through hole 4. Reference numeral 5 denotes a locking protrusion provided at the center of the inner surface of the present application 1, into which the cut and raised piece 3b is embedded, and this engagement protrusion 5 is provided on the leg member of the chair. It is locked in the hole 11.

Then, as in the conventional case, by pressing the opening 2 of the main body 1 against the lower piece of the leg member 10 from below,
While pushing open the opening, the main body 1 is tightly fitted into the lower piece of the leg member 10, and the locking protrusion 5 is inserted into the leg member 10.
It is inserted into the hole 11 and locked.

Effects of the Invention As described above, according to the present application, since the arcuate portion of the metal plate surrounds more than half the circumference of the leg member, the clamping force for the leg member is strengthened, and
The physical strength of the main body itself is increased, which reduces the amount of material required, and since the locking protrusion has a cut and raised piece embedded in it, it is easy to insert the locking protrusion into the hole. It has the advantage of being able to
