Chair armrest structure

This creation is applied to the technical field of furniture, especially a chair armrest structure.

According to the current ergonomic requirements, and in order to increase the comfort of the ride, the chair armrests are usually arranged on both sides of the chair, and the conventional chair armrest structure generally includes a seat and a lower seat. Moreover, the upper and lower seats are mostly fastened by hooks, but the general hooks are only engaged with each other. For the user, it is easy to cause the chair armrest to be seated and lowered due to factors such as sitting posture change, sitting posture, etc. The hook of the seat is loose or even falls off, which causes danger.

The creator has in view of the fact that the above-mentioned conventional chair armrest structure is actually used, and there is still a problem that the upper seat and the lower seat are easy to loose, and the armrest structure of the chair of the present invention is proposed.

The main purpose of the present invention is to provide a chair armrest structure which has a better bonding strength and thus enhances the safety of use.

In order to achieve the aforementioned creative purpose, the technical means used in the present invention is to provide a chair armrest structure, which comprises a lower seat and a upper seat, the lower seat is fixed to one side of the chair, and at least one side of the lower seat Each of the two ends is provided with a hook, and the lower hooks respectively form an elastic column, and the elastic columns protrude from the top to form a hook portion, and the hook portions are adjacent to each other. An engaging surface is disposed at the positions of the elastic columns, and the engaging surfaces are perpendicular to the elastic columns. The upper seat is coupled to the lower seat, the upper seat includes an outer armrest pad and a cover plate, the cover plate is fixedly coupled with the outer armrest pad, and the cover plate is provided with at least two hooks relative to the lower card of the lower seat The engaging hole is larger than the area of the lower hook, and at least two of the engaging holes protrude from one side of the engaging hole, and the other bottom forms abutting portion, and the lower hook card In the engaging holes, the hook portion of each of the lower hooks is received in the opposite engaging hole, and the engaging surface abuts against the surface of the abutting portion, and the free end of the tongue Adjacent to the hook portion away from one side of the engaging surface.

As shown in Figures 1 to 4 and Figure 7, the chair armrest structure of the present invention is a part of a chair 10, and is arranged on the support frame 11 on both sides of the chair 10, and the chair armrest structure It includes a top seat 20 and a lower seat 30. The upper seat 20 includes an outer armrest pad 21, an inner pad 22 and a cover plate 23.

The lower base 30 is fixed to the support frame 11 , and the lower base 30 is provided with a plurality of reinforcing sheets 32 for reinforcing the strength of the lower seat 30 . The lower seat 30 is disposed adjacent to one of the upper seats 20 to Two lower hooks 31 are provided, as shown in the figure, three lower hooks 31 are protruded toward the upper seat 20 at one end of the lower seat 30, and two lower hooks 31 are protruded at the other end. The hooks 31 are respectively formed with an elastic column 310. The hooks 311 are formed at the top end of the elastic columns 310. The hook portions 311 are provided with an engaging surface 312 adjacent to the elastic columns 310. The mating face 312 is perpendicular to the elastomeric posts 310.

The outer armrest pad 21 is formed in a shell shape, and an opening 210 is formed in the direction of the lower seat 30, which is a flexible material, for example, thermoplastic polyurethane (TPU), and the outer armrest pad 21 is bottom. A ring rim 211 is formed in the direction of the opening 210.

The inner pad 22 is received on the inner side of the outer arm pad 21, and the inner pad 22 may be made of a soft material such as a foaming material or a foam.

The cover plate 23 is formed with a side edge 230 extending in the direction of the lower seat 30, and the cover plate 23 is engaged with the inside of the upper seat 20, and the side edge 230 is attached to the retaining edge of the outer armrest pad 21. The inner surface of the 211 is interposed between the outer armrest pad 21 and the cover plate 23, and the outer armrest pad 21 and the cover plate 23 are fitted and fixed to each other. The cover plate 23 is provided with a plurality of engaging holes 240 with respect to the lower hooks 31 of the lower seat 30. The engaging holes 240 are larger than the area of the lower hooks 31, and one of the engaging holes 240 The side protrusions are provided with a tongue piece 241, and the bottom side of the other side is formed with abutting portion 242. The lower hooks 31 are engaged with the engaging holes 240, that is, as shown in the drawing, the engaging holes 240 correspond to each other. The lower hooks 31 are disposed in five, and the hook portions 311 of the lower hooks 31 are received in the engaging holes 240, and the engaging surface 312 abuts against the surface of the abutting portion 242. The free end of the tab 241 is adjacent to a side of the hook portion 311 away from the engaging surface 312, thereby preventing the lower hook 31 from coming off the engaging hole 240, thereby effectively fixing the lower hook 31 and the Waiting for the hole 240 In combination, the bond between the lower seat 30 and the upper seat 20 is improved. The tongue piece 241 is not required to be disposed in each of the engaging holes 240. The tongue piece 241 can be disposed in at least one of the engaging holes 240 according to the designer's needs.

When assembled, the outer armrest pad 21, the inner pad 22 and the cover plate 23 are pre-assembled to form the upper seat 20, and the engaging holes 240 of the upper seat 20 are formed as shown in FIGS. 4 and 5. The lower hooks 31 of the lower seat 30 are aligned with the engaging holes 240 and the lower hooks 31. The following corresponds to the single engaging holes 240 and the lower hooks 31. The hook portion 311 of the lower hook 31 abuts against the abutting portion 242, and the elastic column 310 has an elastic force, and can be elastically bent toward the tab 241 of the engaging hole 240, as shown in FIG. As shown in the figure, the hook piece 241 is elastically bent upwardly, and the hook portion 311 of the lower hook 31 is inserted into the engaging hole 240, and the same as shown in FIG. When the hook portion 311 of the lower hook 31 extends into the engaging hole 240, the elastic post 310 of the lower hook 31 elastically recovers, so that the engaging surface 312 of the hook portion 311 is attached to the hook portion 311. The surface of the abutting portion 242 is detached from the tongue piece 241, and the tongue piece 241 is elastically restored to the original state, and is formed behind the lower hook 31. Therefore, when the upper seat 20 and the lower seat 30 are received vibration The hook portion 311 of the lower hook 31 is restricted by the end surface of the tongue piece 241 and does not come out in the direction of the tongue piece 241 to form an effective engagement state, so as to avoid the upper seat 20 and the lower seat 30 from being separated from each other. Out, increase the security of use.

The present invention has been described in terms of the above embodiments and variations, and all the embodiments and variations of the present invention are merely illustrative and limiting, and the various features of the chair armrest structure including the above features are based on the spirit and scope of the present invention. Changes are covered by this creation.
