Description

[Detailed Description of the Invention] The present invention relates to anti-slip equipment for furniture legs such as chairs and tables.

Conventionally, anti-slip devices installed on pipe legs of chairs, tables, etc. are often made of synthetic resin materials such as ABS resin, but legs made entirely of hard or semi-hard synthetic resin materials are Although they are easy to install, they are slippery when they come in contact with the floor, and those made of soft synthetic resin materials such as soft PVC tend to come off the legs after installation, so they must be installed using special fasteners or other means. Therefore, the workability is poor and satisfactory results cannot be obtained.

The present invention improves such drawbacks and has various other features.The nine mounting bands attached to the legs are molded from a hard or semi-hard elastic material with little deformation, and the outside is made of a soft elastic material for the floor surface. Form a contact zone and attach it to the corresponding contact zone 9
It is made by engaging the joints of the bands, so that it does not slip easily, can be firmly and easily attached to the legs, and each section of the band does not separate during use, so it can be used for a long time. .

This will be explained below along with examples.

The one shown in the figure is fitted along the floor surface of a leg 1 extending in the horizontal direction of a chair, etc., and a mounting belt 2 is provided in a shape that almost follows the outside of the iron leg. be.

The nine mounting bands are made of polyamide such as nylon 6, polyacetal such as Duracon, polycarbonate, polyester, polyimide, polyphenylene oxide, AB
S resin, hard or semi-hard polyvinyl chloride, epoxy resin, phenol resin or other thermosetting resin, fiber-containing reinforced resin, hard or semi-hard rubber or other hard or semi-hard elastic material with an opening at one side. It is made into a cylindrical body with an arc-shaped cross section, and the outer side has a wall thickness of 4 toward the bottom, and there is a conical retaining protrusion 5 with a rounded tip at approximately the center of the inner surface, which extends from the outer surface to the inner surface. It has a hole 6 to pass through, both ends are slightly inwardly recessed 7, and a recessed portion 8 is provided across the opening of the inner surface of the hole located outward from the ends.

On the other hand, on the outside of the 9 mounting bands, soft rubber with anti-slip effect, soft synthetic rubber, soft polyvinyl chloride, polyurethane, polyethylene, ethylene-vinyl acetate copolymer resin,
The abutting band 9 is formed of polypropylene or other soft elastic material.

At the joint between the corresponding contact zone and the attachment zone 9, after molding the attachment zone 9, by molding the contact zone, a part of the resin material etc. that molds the applicable connection zone will be formed into the hole of the attachment zone 9, It extends continuously over the recesses and recesses, and hardens while enclosing the walls between the holes and the recesses of the attachment band, so that they are firmly engaged with each other.

The portion of the contact zone that contacts the floor surface is preferably curved in a wave shape 10, and is preferably formed in an arc shape that is substantially continuous with the outline of the attachment zone 9.

If the above-mentioned engaging protrusions correspond to the mounting holes 11 provided at appropriate locations on the floor surface of the leg, and are properly driven in with a hammer or the like and fixed, the mounting band 9 will have a certain degree of elasticity and will be securely attached. There is no risk of the legs falling off because there is little deformation, and there is no risk of them rotating or shifting in the longitudinal direction even when a load is applied to the legs. In addition, the soft elastic material constituting the abutting band 9 is molded onto the outer surface of the mounting band 9 using the mounting band 9 as a mold. The material passes through the hole provided in the mounting 9 band and both ends of the mounting 9 band and enters the recess communicating with the openings at both ends of the hole, and the abutting band 9 is provided with a part of the mounting 9 band being embraced. Because of this, the two zones are reliably joined, and unlike those bonded with adhesive or the like, they do not peel off during use, and can be used for a long period of time.

The molding material for the abutment band 9 is appropriately selected so that the attachment band 9 does not undergo thermal deformation during molding, and preferably materials of the same type, such as hard or semi-hard vinyl chloride and soft vinyl chloride. By using a combination of materials, it is possible to strengthen the adhesion of the joint (surface).

Claims (1)

[Scope of utility model registration request] The mounting strip 9 to be attached to the furniture leg is made of a hard or semi-hard elastic material with little deformation, and is formed into a cylindrical body with an arc-shaped cross section that opens at a biased portion to one side, and an engaging protrusion is provided approximately at the center of the inner surface of the mounting strip 9. and a hole opening from the outer surface to the inner surface is provided, and both ends of the section to be taken are recessed to form a recessed part extending from the end to the opening of the inner surface of the hole, and the floor of the outer surface of the mounting section is recessed. The zone that comes into contact with the surface is made of a soft elastic material that has an anti-slip effect, and the soft elastic material is continuously extended over the holes, recesses, and recesses of the mounting zone 9, and the area between the holes and the recesses of the attachment zone 9 is formed. A non-slip furniture leg characterized by being provided in a state that hugs the wall part.
