Description

[Detailed description of the invention] This invention relates to a chair leg cover device, and more specifically, a plastic cover is attached to the support legs provided radially at the lower end of the main legs of the chair, and the surface finishing process of the support legs is omitted or reduced. To prevent damage to the surface of the supporting leg, the base end of each supporting leg cover is joined to the main leg in close contact with each other to form an annular part at the base of each supporting leg cover, and a ring member such as a snap spring is fastened to this annular part. The present invention relates to a leg cover device that prevents each cover from falling off by attaching a leg cover.

Referring to the attached drawings below, reference numeral 1 in the figure indicates the main landing gear, and on the outer periphery of its lower end, there are supporting legs 3, each having a caster mounting nut 2 fixed to the bottom surface of the tip, at a constant angle, as shown in FIG. radially arranged, each supporting leg 3
The base is formed by bending both side walls inward to form tapered edges 4, 4, joining these tapered edges 4 to the tapered edges 4 of other adjacent supporting legs 3, and welding them at predetermined positions. The arc-shaped base end 5 of each support leg is welded to the main leg 1 to connect the main leg 1 and the support leg 3, and each support leg 3 is covered. As shown in Fig. 1, the cover 6 has an opening 7 on the bottom surface for mounting the caster.
The base 8 is slightly inflated to both sides, and the opening edges 9 on both sides can be joined to the opening edges 9 on the base side of the adjacent cover, and the upper and lower base ends are arcuate. A groove 12 or 13 is formed on the outer surface of the edges 10, 11, and a step 15 is formed on the upper proximal edge 10 for hooking the lower edge of a bellows tube 14 covering the main leg. the groove 12,
13. When each support leg is covered with a cover 6, the stepped portion 15 has an annular groove 1 as shown in FIG.
2, 13, and a stepped portion 15, and this groove 12, 13
By fitting the tightening ring 16, for example, a snap spring, and tightening each cover 6 in a direction that brings it into close contact with the main leg 1, it is possible to prevent the covers 6... from coming off from the supporting leg 3 or from wobbling. are doing.

Reference numeral 17 in FIG. 4 indicates a support piece for fixing the nut 2, which is welded to the bottom surface of the tip of each support leg 3. When this support piece 17 is welded to the support leg 3, there are irregularities caused by welding on the surface of the support leg. In order to prevent this from occurring, an opening 18 for inserting a welding rod is formed at the tip of the support leg 3 so that the support piece 17 can be welded inside the support leg 3.

The landing gear cover device of the present invention as described above not only achieves the original purpose and effect of the covering by covering each supporting leg 3 at the lower end of the main landing gear with a cover 6, but also achieves the original purpose and effect of the covering by covering the base 8 of each cover. Since the opening edges 9 on both sides are closely joined to the side opening edges 9 of adjacent other covers 6, each cover 6 can be fitted to each support leg 3 without any wobbling or misalignment. In addition, the tightening rings 1 such as snap springs can be positioned in the grooves 12 or 13 of the upper and lower proximal edges 10 and 11 of the base 8.
6, each cover 6 can be tightened in the direction of pressing it against the outer surface of the main leg 1,
This makes it possible to completely prevent each cover from falling off and rattling. Also, from this point of view, the bellows tube 14 for covering the main landing gear is attached to the stepped portion 1 of the upper proximal edge 10.
If the bellows tube 14 is fitted and engaged with the bellows tube 5, it will prevent the bellows tube 14 from coming off upward, and this bellows tube 14
It is also possible to prevent each cover from coming off.
