JP2000079028A - Nonslip cover for furniture leg - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a nonslip cover for furniture legs that has a nonslip face and a slip face both covering, when used, a furniture leg in a manner that only te nonslip face is used while the furniture is moved and it is changed into another nonslip face when the furniture is set in position. SOLUTION: A bag element A of a rubber material or a soft elastomeric material offering cushioning effects has a bottom portion 1, a peripheral portion 2, a level difference part 1a, and an opening 3. The level difference part 1a is provided with a slip face 4 of slidable material. When the bag element A is set on a furniture leg B, a smaller load of the furniture leg B on the bottom portion 1 of the bag element A places only the slip face 4 into contact with a ground plane C, and a larger load forces a nonslip face 5, together with the slip face 4, into close contact with the ground plane C.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furniture leg having two functions of slipping and non-slipping between a floor and a leg by covering a leg, such as a chair, a step, a bed, etc., which comes into contact with the floor. About the non-slip.

[0002]

2. Description of the Related Art As this kind of prior art, a bag-like cover made of a soft and resilient rubber material is fitted into four legs of a table chair, and the chair is set on a flooring floor. It is widely known as a non-slip or for preventing a scratch on a flooring floor.

[0003]

However, in the case of the above-mentioned prior art, since the rubber cover is fitted when the chair is to be cleaned up after use of the chair at a dining table or the like, the chair must be lifted from the floor with both hands and moved. The problem remains that older people, children, and people with leg disorders have to work harder.

[0004] In addition, when the table and the chair are slightly extended while being surrounded by the table, the chair cannot be moved by sliding, so that the user stands up and lifts the leg of the chair from the floor. There remain issues such as being unable to move unless lifted and floated.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention covers an end portion of a leg B such as a chair, a platform, a bed, etc., which comes into contact with a grounding surface C, as described with reference to FIGS. The bag body A that can be formed is composed of an outer peripheral part 2, an opening part 3, a bottom part 1, and a step part 1a.

[0006] The step portion 1a of the bag A made of a soft elastic rubber material having a cushioning property is a projection slightly higher than the non-slip surface 5 provided on the bottom portion 1 and has a stepped portion 1a in a sphere.
The sliding surface 4 is provided integrally with the non-slip surface 5, and the sliding surface 4 is made of a material different from the non-slip surface 5 by, for example, sticking a Teflon resin sheet having a small friction to easily contact with the ground surface C. It consists of.

As described above, the contact surface C on the flooring floor
When the bag A over the legs B of the tools is not used at all times, the sliding surface 4 comes into contact with the ground surface C without interruption due to the weight of the tool body, and the non-slip surface 5 is separated from the ground surface at a predetermined interval. Floating from C.

In the bag A, a load is applied to the legs B of the tools as shown in FIG. 2, that is, the user sits down on a chair or the user rests on a step. Or
When the user enters the bed, the step portion 1 is reduced and deformed flat and the non-slip surface 5 falls to the ground contact surface C, and when the tools are used, the non-slip surface 5 comes into close contact with the floor surface. Prevent slip.

As described above, when the tools are empty (self-weight), the sliding surface 4 that is easy to move on the flooring of the floor works, and the user uses the sliding surface 4 to add weight without weight of the user. The surface 5 comes into contact with the grounding surface C and is stably installed on the flooring floor.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal section of a non-slip furniture leg according to the present invention, which has a cushioning property with a soft elastic body adapted to a similar round or square shape that can be fitted to the shape of a leg B of a household tool. The bag A is fitted to the leg B so as not to fall off with a rubber material.

The bag body A comprises a bottom portion 1, an outer peripheral portion 2, an opening 3, and a step portion 1a. In this embodiment, the step portion 1a has a height higher than the non-slip surface 5 as shown in FIG. It is hemispherical and has a sliding surface 4 on its surface. This sliding surface 4
Is formed by tightly joining a sheet material of Teflon resin material with low friction to the stepped portion 1a, but it may be formed by insert or fitting with another material.

[0012] Then, as shown in FIG.
In this case, a predetermined load is applied to the chair,
A bet or the like will take the user's weight. Upon receiving this weight, the step portion 1a having cushioning property is deformed into a flat shape, and the non-slip surface 5 falls on the ground surface C, so that the slide surface 4 and the non-slip surface 5 come into contact with the ground surface C at the same time. The anti-slip surface 5 made of a rubber material having a large friction area and a large friction is in close contact with the flooring floor.

FIGS. 3 and 4 show the sliding surface of the bag A when the anti-slip 4 of the leg B of the furniture according to the invention is mounted on the leg B of the chair and the leg B 'of the bed as bedding. 4 is in contact with the flooring floor surface because it does not receive the weight of the user, the non-slip surface 5 is separated from the flooring floor surface, and these tools can be slid and moved without being lifted from the flooring floor surface. It is.

Next, a second embodiment will be described with reference to FIGS. 5 and 6. Referring to FIGS. 5 and 6, a cylindrical body having a bottomed first bottom portion 7a made of a non-elastic ABS resin or the like along the inner wall of the bag body A '. The receiving body 6 is fitted into the bag A 'by a loose fit, and the receiving body 6 has a coiled return spring 7 which is reduced by receiving a pressing force. Of the first bottom portion 7a, the return spring 7 contracts when a load is applied to the leg B, and restores its original natural length by removing the load. .

As described above, the leg B according to the second embodiment of the present invention is designed so that the user can manually stand and stand on the chair by the leg B by specifying the leg B of the chair. Borrow,
It can be used for handicapped people who need help with a cane.

That is, since the four legs B of the chair are provided with the receivers 6 and the return springs 7 each having a predetermined length, the seat surface of the chair is raised by the return springs 7. Then, the user puts his buttocks on the seat while standing, and bends his legs to reduce the return spring 7 depending on the weight, but when the user stands up from the seat, the return spring 7 tries to lift the weight. The repulsive force acts on the seating surface, so that it can stand up with a slight leg force and move away from the seating surface.

[0017]

The present invention has the following advantages because it operates as described above. By mounting it on four legs such as household furniture, for example, a table chair, a step board, and a bed, the flooring surface and the sliding surface are in contact with each other when these tools are not used. Since the floor can be moved by sliding, it is possible to provide a non-slip furniture leg that can be moved without lifting the tools from the floor.

Further, when the user puts weight on a chair, a platform, a bed, or the like, and uses the weight, the slip surface of the bag body is deformed and flattened due to the pressure of the weight, so that the non-slip surface becomes a ground contact surface. It is possible to provide a non-slip furniture floor which can be stably attached to the floor surface and stably adhered to the floor surface.

Next, in the second embodiment, the chair for the handicapped and the elderly can be seated in a standing state because the seat surface of the chair is at the buttocks of the user. By applying hand force to the armrest of the chair, it is possible to provide a non-slip furniture leg with a return spring that can rise without human assistance.
