Description

[Detailed Description of the Invention] Industrial Application Field The present application 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, for example, 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. In addition to being expensive, there was a risk of damage due to cracks during long-term use.

Means for Solving the Problems Therefore, the present application provides a metal plate that has an opening into which a pipe-shaped leg member having a hole can be inserted, and that has a through hole inside the opening except for both ends. The inner surface of the main body is made of synthetic resin with an arc-shaped cross section.
The leg member is characterized by a locking protrusion that locks into a hole in the leg member. Preferably, the main body is thick at the center and gradually thinner toward both ends in the curved direction. Furthermore, in order to increase the elasticity of the present invention, the metal plate is made of steel.

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 locked in a hole provided in the leg member.

Embodiment The embodiment of the present application will be described in detail below based on the drawings. 1 has an inner peripheral surface curved to fit the lower outer periphery of a leg member 10 made of a pipe, an outer peripheral surface that is thick in the center, 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 whose thickness gradually decreases toward both ends in the curved direction. A metal plate, preferably a steel plate 3, is embedded by insert molding except for both ends of the opening 2. This steel plate 3 is provided with through holes 4 including many slits, so that the inner and outer layers of the main body 1 bordered by the steel plate 2 are integrally connected via the through holes 4. be done. Reference numeral 5 denotes a locking protrusion provided at the center of the inner surface of the present application 1, which locks into a drainage hole 11 provided in the leg member 10 of the chair.

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 locks in the hole 11 of.

Effects of the invention Since the present application is constructed as described above, the physical strength of the main body is reinforced by embedding the metal plate, the amount of synthetic resin used can be reduced, and it can be obtained at low cost. , the possibility of damage due to cracks, etc. can be avoided and the durability is excellent. Furthermore, according to the present application, since the metal plate is embedded inside the opening except for both ends, the metal plate can be inserted up to both ends of the opening. Since the opening is easier to open than when the plate is buried, even if a metal plate with strong elasticity is used to obtain a large fit and retention force, it can be easily fitted into the leg member. When the main body is made of a steel plate, the elastic force of the main body is increased, and the main body has the advantage that it can be easily attached to the leg member.
