Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a leg cover for covering a leg portion of a chair, and more particularly to a chair leg cover structure that can be easily fixed and disassembled on the leg portion.

[0002]

[Prior art]

 Conventionally, the leg portion 14 of the chair is formed radially around the fitting portion into which the leg support of the seating portion is inserted and fixed. The leg portion 14 is formed of a metallic pipe due to design requirements such as durability and rigidity, but in order to relieve the metallic impression and improve the appearance, the leg cover 11 made of synthetic resin is used. Is covered (see FIG. 4). The leg cover 11 has a substantially U-shaped cross section with a downward opening so that the leg cover 11 can be covered from above along the shape of the leg portion 14. Then, as shown in FIG. 5, on the concave portion 13 side of the leg cover 11, a cylindrical body 15 which can be inserted into a hole penetrating at a predetermined position of the leg portion 14 and screw threads are provided on the inner peripheral surface thereof. Is formed, or a cylinder having separate screw threads is separately inserted into the cylinder, and a screw 17 is fitted from the lower side of the leg 14 so that the leg cover 11 and the leg 14 are separated from each other. It was fixed.

[0003]

[Problems to be solved by the device]

 However, according to such a fixing structure, when disassembling, it is necessary to remove the screws 17 from all the leg portions 14 (five in FIG. 4) and remove the leg cover 11, which is very troublesome. I will end up. Therefore, the leg cover 11 was attached and discarded as an unsortable product, and the leg cover 11 and the leg portion 14 could not be reused. In this way, manual work is usually very expensive, and even if it is a reusable material, it is often discarded because the cost of disassembling / separating it and the merit of reuse are inconsistent. In other words, when reusing, the most problem is the trouble of separating the materials, and normally, once assembled, it cannot be disassembled without very troublesome manual work.

In view of this, it is an object of the present invention to provide a structure of a leg cover of a chair that allows the legs and the leg cover to be easily attached and detached to facilitate disassembly work.

[0005]

[Means for Solving the Problems]

 In the present invention, as a means for solving the above-mentioned technical problems, a plastic decorative cover attached to each of a plurality of leg portions radially formed on a leg support supporting a seating portion of a chair. In the leg cover of the chair, the inner wall of the leg cover of the decorative cover into which the leg is fitted is provided along both sides of the leg, and the inner wall of the leg cover is integrally formed with the inner wall of the leg cover. The leg cover structure of the chair has a structure in which claws facing each other at right angles are formed, and the claw elastically expands to easily detach the decorative cover.

[0006]

[Action]

 With the above configuration, the claws on the recess side of the decorative cover elastically open and spread, and the legs can be easily inserted into and removed from the recess. Also, once the legs are fitted into the recesses, the claws serve to prevent the decorative cover from coming off, and the entire inner wall on the recess side holds the legs securely so that the legs are securely held in the recesses. it can.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The leg cover 1 is made of plastic as in the conventional case, and is composed of a plurality of decorative covers 2 having a substantially inverted U-shaped cross-section that follows the number and shape of the leg portions 4 radially formed from the fitting portion of the leg support of the chair. Has been formed. FIG. 1 is a sectional view showing the relationship between the decorative cover 2 and the leg portion 4.

On the concave portion 3 side of the decorative cover 2, two inner wall portions 6 are formed along the lengthwise direction thereof at intervals corresponding to the width of the leg portions 4. The inner wall portion 6 is formed at the same time as the formation of the leg cover 1, and a plurality of inner wall portions 6 are provided between each of the inner wall portions 6 and the decorative cover 2 so as to maintain the rigidity of the inner wall portion 6 and maintain the space therebetween. The ribs 8 are formed at predetermined intervals.

On the other hand, two claws 10 are integrally formed on the inner wall portion 6 on the tip side near the grounding portion where the casters of the decorative cover 2 are formed. The claws 10 are formed so as to face each other at substantially right angles from the lower end of the inner wall portion 6 toward the center side of the decorative cover 2. The ribs 8 are not formed on the inner wall portion 6 where the tabs 10 are formed. Each claw 10 is a plate having a predetermined width and length, and when the leg 4 is fitted into the recess 3, the two claws 10 serve to prevent the decorative cover 2 from coming out upward. It is a thing. The claw 10 is also integrally formed at the same time as the leg cover 1 is formed, and has a certain elasticity because it is made of plastic.

Next, a description will be given of the operation of the work of removing / attaching the leg cover 1 thus formed from the leg portion of the chair. First, in a state where the leg cover 1 is fixed to the leg portion 4, the claw 10 and the inner wall portion 6 around the claw 10 are held by the elasticity so as not to come off the lower surface side of the leg portion, and the leg portion The side surface can be elastically clamped, and the leg portion 4 can be fixed at a predetermined position of the concave portion 3 of the decorative cover 2.

Further, each leg portion 4 is covered by the decorative cover 2 securely and without rattling, and the decorative cover 2 cannot be removed unless the claws 10 located below the leg portions 4 are expanded. Therefore, in a normal use condition, the decorative cover 2 is sufficiently fixed, and the decorative cover 2 does not come off at some time.

Next, a case where the leg cover 1 is removed from such a fixed state will be described. As shown in FIG. 1, by pushing the claw 10 slightly outward with a finger, the claw 10 is easily pushed open to the width of the leg portion 4 and the decorative cover 2 can be removed from the leg portion 4. . In this case, since the claw 10 itself has elasticity, the inner wall portion 6 also has elasticity, and the rib 8 is not formed in the vicinity of the claw 10, it is easier than the other inner wall portions 6. The claw 10 can be pushed out. Therefore, unlike the prior art, it is not necessary to remove the decorative cover 2 for each leg 4 by using a tool or troublesome manual work, and the work can be performed easily and quickly. Therefore, even when disassembling the product prior to disposal, it can be removed easily and effortlessly, so that it can be securely disassembled and can be sorted by material, and both the leg 4 and the leg cover 1 can be reused. Open way.

On the other hand, since the claws provided on the concave portion 3 side of the decorative cover 2 can be elastically opened and expanded in this way, even when the decorative cover 2 is put on the leg portions 4, one claw 10 is used as a leg. It can be easily attached by pressing it against the side surface of the part 4. That is, the decorative cover 2 can be continuously fitted into the leg portions 4 one after another by the pushing operation. Therefore, the time required for assembling the chair can be shortened.

Further, unlike the prior art, since it is not necessary to form a cylindrical body having screw threads on the inner circumference, a complicated molding die is not required, the cost of the die can be reduced, and separately. No manual work is required to insert a pipe with screw threads. Further, since it is not necessary to provide a hole in the leg portion 4, it is also effective in that respect. Also, no screws are needed.

[0015]

[Effect of device]

 As described above, according to the present invention, the inner wall portion along the side surface of the leg portion of the chair is integrally provided on the concave side of the decorative cover of the leg cover, and is integrally provided at the lower end of the inner wall portion, and the elastic expansion and expansion is possible. Since the legs are fixed by the claws that prevent the legs from coming off, the leg cover can be easily attached to and removed from the legs. As a result, not only the efficiency of the assembling work is improved, but also the disassembling work does not take time and effort, so that the disassembling work of the leg portion and the leg cover can be executed, and each can be reused.
