Description

Quick assembly structure of armrest

The present invention provides a technical field of office chair armrests, especially a designer who technically provides a quick assembly structure of armrests.

According to the conventional method of assembling the armrest of a chair, an armrest frame is also provided. The top of the armrest frame presents a T-shaped top shape, and two stepped perforations run through the bottom surface of the T-shaped top shape to provide Two screws are inserted, and the bottom surface of the armrest cushion group is provided with two screw holes corresponding to the two stepped through holes, so that the two screws are threaded and locked to the two screw holes, and the armrest frame and the armrest cushion group can be locked and combined.

However, the above-mentioned conventional chair armrest assembly requires two additional screws, and additionally requires hand tools, that is, it uses hand tools to tighten the screws to achieve the purpose of fixing. Therefore, on the one hand, you need to align the two screw holes of the armrest cushion set with the two perforations of the armrest frame, and then try to thread the lock screw with the other hand to determine whether the holes are aligned, and then lock it with a hand tool. It is tedious, inconvenient and time-consuming, and there is room for improvement.

The present invention provides a designer of a quick assembly structure of an armrest.

In order to enable your reviewer to have a further understanding and understanding of the purpose, features and effects of the present invention, the detailed implementation methods and drawings are as follows: referring to the first to third figures, the present invention provides an armrest The quick assembling structure includes: an armrest frame 10 with a horizontal fixing base 11 at the top end. The front and rear ends of the fixing base 11 are respectively provided with a front plug block 111 and a rear plug block 112. The front The length of the plug block 111 is greater than that of the rear plug block 112, and a buckle 113 is further provided between the front and rear plug blocks 111 and 112; in this embodiment, the buckle 113 is formed with a rectangular groove 113a with a bottom The end is also provided with a through hole 113b to the bottom of the fixing seat 11; an armrest pad 20 is wrapped around an inner seat body 21 with a sleeve opening 210 on the bottom surface to be sleeved on the fixing seat 11 of the armrest frame 10. The inner seat body The front and rear ends of the 21 socket 210 are provided with the front and rear plug blocks 111 and 112 of the fixing seat 11. There are recessed slots 211, 212, and the inner end surface of the sleeve 210 is provided with a spring buckle 213 that can be positioned opposite to the buckle seat 113 of the fixing seat 11. The armrest pad 20 is formed by the recessed front and rear ends. The sockets 211, 212 and the front and rear plug blocks 111, 112 of the fixing seat 11 are inserted into each other and then hooked by the spring buckle 213 and the buckle seat 113, so that the armrest pad 20 and the fixing seat 11 form a fixed point and cannot be removed. In this embodiment, the inner seat body 21 is made of a hard plastic material, and the spring buckle 213 is an undercut shaped integrally formed by the inner seat body, and its undercut side is inserted behind the fixed seat 21 The block 112 can be hooked into the rectangular groove 114 on the buckle base 113, and the front and back length of the sleeve 210 is slightly longer than the length of the fixing base 11, so that it has a length difference, and the width is just enough to accommodate the fixing base 11. The insertion is limited, and the length between the front and rear plug blocks 111 and 112 of the fixing seat 11 is slightly longer than the front and back length of the socket 210, and the protruding length of the back block 112 is determined by the length between the socket 210 and the socket 210. The length difference of the fixing base 11 is limited.

With the composition of the above components, when assembling, please first refer to the fourth figure, first use the inner seat body 21 of the armrest pad 20 to sleeve the fixing seat 11 of the armrest frame 10, and place it in the front end After the concave slot 211 is used for inserting the plug block 111 in front of the fixing base 11, the front and back length of the socket 210 is slightly longer than the length of the fixing base 11, and the protruding length of the plug block 112 after the fixing base 11 is The length difference is limited. Therefore, the socket 210 is inserted into the bottom of the socket 11 with the recessed slot 211, and the socket 210 can be inserted into the socket 11 (as shown in the fifth figure). Show), at this time, the spring buckle 213 on the inner seat body 21 will be pressed by the buckle seat 113 and elastically compressed, and then the armrest pad 20 will move forward Push back, so that the rear connector block 112 of the fixing base 11 is inserted into the concave slot 212 at the rear end of the socket 210, and the length between the front and rear socket blocks 111 and 112 is slightly longer than that of the socket 210 The front and rear lengths, so the front and rear plug-in blocks 111, 112 can fall into the recessed slots 211, 212 of the front and rear ends respectively. At this time, the position of the spring buckle 213 can also fall into In the buckle groove 113a on the buckle seat 113, it is elastically pushed out to form a fixed-point latching position with the buckle groove 113a, so that the front and rear plug blocks 111, 112 can be inserted into the recesses of the front and rear ends The joint positioning in the slots 211 and 212 that cannot slide out at the same time (as shown in the sixth figure).

In summary, the quick assembling structure of the handrail of the present invention can achieve the following effects and advantages, so the object of the present invention can be achieved:

1. Simple structure: Since the present invention only consists of an armrest frame 10 and an armrest pad 20, the structure is simple and easy to manufacture.

2. Fast assembly: The present invention only needs to insert the armrest pad 20 and the fixing seat 11 of the armrest frame 10 with each other at both ends, and then use the elastic buckle 213 and the inner seat body 21 integrally formed in the armrest pad 20 The buckle seat 113 on the fixed seat 11 forms a fixed-point locking limit, so it can be assembled quickly and can be completed without tools.

3. Easy to disassemble: Since the bottom end of the buckle 113 on the fixing seat 11 is provided with a through hole 113b to the bottom of the fixing seat 11, the through hole 113b can be inserted into the column to push the elastic buckle 213 to withdraw it To achieve the purpose of quick and easy disassembly due to the locked state of the buckle base 113.

To sum up, the present invention has excellent practicality in similar products. At the same time, we have checked the technical data of this type of structure at home and abroad. The literature has not found the same structure. Therefore, The present invention actually has the requirements for a patent for invention, and an application is filed in accordance with the law.

However, the above are only the preferred and feasible embodiments of the present invention, so any equivalent structural changes made by applying the specification of the present invention and the scope of the patent application should be included in the patent scope of the present invention.
