Abstract

(57) [Summary] [Problem] When sitting on a chair, there is no discomfort with the floor,
An object of the present invention is to develop a structure for protecting the legs of a chair, which has a good appearance, is clean, does not easily scratch the floor, does not easily peel off, and lasts a long time. SOLUTION: In a leg portion 2 of a chair 1, a blind hole 3 having an appropriate depth is drilled in a leg end face, a rubber pillar 4 is inserted into the blind hole, and a synthetic fitting is fitted in the blind hole. A leg protection structure for a chair, wherein a resin cap 5 is press-fitted.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a leg protection structure for a chair.

[0002]

[Prior art]

 Conventionally, chairs used in homes, etc. are such that when a person sits down, the chair is pulled from the table, and when standing up, the chair is pushed toward the table, and the chair is slid each time, The paintwork on the floor surface was easily scratched, and when sliding the chair, it was heavy and sounded.

[0003] On the other hand, in order to protect the floor from being damaged by the tip of a chair leg, there is a type in which a felt or a plastic part is adhered to a leg tip, but cotton dust, hair, and the like are attached to the felt. It adhered and was very unsightly and dirty, and it was easy to peel off and did not last long.

[0004]

[Problems to be solved by the invention]

 Therefore, the present invention eliminates the above-mentioned disadvantages, and when sitting on a chair, there is no feeling of incongruity with the floor, the appearance is good, and the floor is clean, hard to be scratched, hard to peel off, and long-lasting. The purpose of this invention is to develop a leg protection structure.

[0005]

[Means for Solving the Problems]

 As a specific means, a blind hole is drilled in the distal end surface of the leg portion of the chair, a rubber column is inserted into the blind hole, and a synthetic resin fitting is fitted to the distal end of the rubber column. A chair leg protection structure characterized in that a cap is press-fitted.

[0006]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In a leg (2) of a chair (1), a blind hole (3) having an appropriate depth, for example, 24 mm and a diameter of 13.3 mm, is formed in a leg end face. ), A rubber pillar (4) having a diameter of 10 mm and a length of 25 mm is inserted into the blind hole (3), and a synthetic resin cap (5) fitted into the pillar (4) is inserted. ) [The outer diameter is 13 mm, the inner diameter is 9.8 mm, the height is 11 mm, and the bottom thickness is 8 m].

[0007] A rubber (hardness: 40 °) column (4) was subjected to a cushion resistance test. As a result, after repeated compression of 10,000 times, 3.56 mm was changed to 3.11 mm, and as a strain, Once, it became 0.45 mm, but after standing for 12 hours, it was restored to 3.37, and the distortion was 0.19 mm, so there was no problem. Also, a cap (5) made of synthetic resin is weighed 16 kg on a floor plate and reciprocated 2,000 times with a stroke of 400 mm 2,000 times, and the total traveling distance is 1,600 m. No visible scratches occurred. Further, the cap (5) is provided with an air hole (6) having a diameter of 1 mm at the bottom to facilitate mounting of the cap.

[0008]

[Effect of the invention]

 According to this invention, since the synthetic resin cap (5) is fitted to the leg of the chair via the rubber pillar (4), when the chair is slid, light and no sound is produced. In addition, dust such as cotton dust does not adhere to the leg tip, it is hard to come off, it is long-lasting, looks good in appearance, and has cushioning resistance. The floor is not damaged. In addition, since the air hole (6) is provided on the bottom surface of the synthetic resin cap (5), when the synthetic resin cap (5) is pressed into the blind hole (3), air escapes from the air hole (6). Therefore, it has an extremely beneficial effect such as easy mounting.
