Abstract

The utility model provides a fixed knot who combines between chair handrail and cushion constructs, make the protruding body of establishing of the protruding combination department of a cushion and handrail, and make the end of protruding body establish a portion of inserting again, then establish a recess groove anastomotic with protruding body on the handrail that this protruding body corresponds the department, and make the tank bottom department of recess groove concave again and establish a slot, more make protruding body and the recess groove between be the cooperation of oblique taper slightly simultaneously, and then make the protruding body that cushion and handrail correspond and the insertional back of closing that recess groove is tight each other, insert the portion of closing and also just in time can insert in the slot, then with a screw with handrail locking on the cushion again, make through the cooperation between protruding body and the recess groove, not only let the handrail more firm combine on the cushion and difficult emergence is not hard up outside, also let the handrail can be more rapid equipment on the cushion simultaneously.

Description

Fixing structure for combination between chair armrest and cushion

Technical Field

The utility model relates to a fixed knot who combines constructs between chair handrail and cushion, it is protruding through the bottom surface department that combines the handrail at the cushion and establishes a protruding fit, and the recess that can supply protruding fit to coincide to pack into is then established to corresponding handrail combination department, then fixes the handrail lock on the cushion with a screw, the equipment operation between completion handrail and the cushion that can be rapid.

Background

The armrests of a common office chair are fixed to the two sides of the bottom surface of a seat cushion, such as the armrests of Taiwan

TW106204476 and TW092212609 are both patents in which a fixing portion is extended from the bottom end of each armrest to the bottom surface of the cushion, the fixing portion is provided with a long slot hole for a screw to pass through, and the bottom surface of the cushion at the corresponding position is provided with a screw hole for the screw to thread and lock.

The simple method for locking the handrail has the advantages that the combination and assembly operations are easy, the distance between the two handrails can be adjusted through the design of the long slotted holes at the handrail fixing part or the design of the front and rear rows of the cushion bottom screw holes, the front and rear positions of the handrail locking can also be adjusted front and rear, and although the design is not wrong, the handrail can hardly be adjusted any more after being fixed, even the handrail can be locked at a generally proper position during the assembly in a factory, and the consumer can hardly adjust the handrail position when using the handrail, so the handrail is almost vain design.

In addition, no matter three or four screws are used to fix the armrest fixing part on the seat cushion, the armrest is usually pressed by downward force after a period of use, and meanwhile, outward or inward force is applied, so that the problem that the screws are loosened easily under the action of repeated force is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a corresponding department that combines between cushion and handrail is equipped with the convex body and the concave groove that are slightly taper shape complex, lets the handrail assemble on the cushion simply and fast, then only need with a screw lock solid both, just can accomplish the operation of equipment, also makes the cooperation of convex body and concave groove between cushion and the handrail simultaneously, more can improve the handrail and bear the application of force of all directions, lets the difficult phenomenon that the screw is not hard up that takes place of handrail in order to improve aforementioned known handrail and combine on the cushion, outside causing the trouble on the equipment operation, and after the effect of handrail repeated application of force, take place the screw easily again.

The utility model provides a technical scheme that its technical problem adopted is: a convex body is convexly arranged at the position of the seat cushion combined with the armrests, a concave groove for the convex body to be inserted in a matching way is arranged on the armrests at the corresponding position of the convex body, and a screw is arranged to lock the armrests on the seat cushion.

In the above scheme, a slot is further concavely arranged at the slot bottom of the concave groove of the handrail, and an inserting part which can be inserted into the slot in a matching way is arranged at the tail end of the convex combination body of the cushion.

In the above scheme, the convex combination body is matched with the concave combination groove in a slightly oblique cone shape.

Therefore, through the aforesaid the utility model discloses the protruding fit and the recess of the mutual urgent complex of junction between cushion and the handrail not only let this handrail can be more firm combine together with the cushion, more make the handrail can be rapid assemble together with the cushion, also make the handrail after combining more difficult not hard up because of the effect of strength repeatedly simultaneously.

The present invention will be further explained with reference to the drawings and examples.

Description of reference numerals: 1-cushion; 10-screw holes; 11-a convex body; 12 an insertion part; 2-a handrail; 20-punching; 21-a concave groove; 22-slot; 3-screws.

Detailed Description

Referring to fig. 1-3, the armrest 2 of the present invention is combined with the bottom surface of one side of the seat cushion 1 through the lower end of the armrest, a protruding body 11 is protruded from the combination of the seat cushion 1 and the armrest 2, an insertion portion 12 is protruded from the end of the protruding body 11, and a screw hole 10 is disposed at the root of the protruding body 1.

The handrail 2 corresponding to the convex combination body 11 is provided with a concave groove 21, and the groove of the concave groove 21 is further provided with a concave slot 22, and the tip of the combining end of the handrail 2 is provided with a through hole 20.

The convex combination body 11 of the seat cushion 1 and the concave groove 21 of the armrest 2 are matched with each other in a slightly inclined cone shape, and the inserting part 12 and the inserting groove 22 are also matched with each other.

Therefore, by the tight fit between the convex body 11 of the seat cushion 1 and the concave groove 21 of the armrest 2, and the insertion portion 12 and the insertion groove 22 of the two are also inserted into each other, the screw hole 10 on the seat cushion 1 can be aligned with the through hole 20 on the armrest 2, and then the screw 3 is provided to lock the armrest 2 to the seat cushion 1.

Therefore, the seat cushion 1 and the armrests 2 are embedded after tight fit between the convex combination body 11 and the concave combination groove 21, so that the armrests 2 can be more stably fixed on the seat cushion 1, and meanwhile, the armrests 2 cannot be twisted and loosened under the action of forces in different directions.

Furthermore, the convex body 11 and the concave groove 21 are inserted and combined, so that the assembly and combination between the seat cushion 1 and the armrest 2 are simpler and easier, and only one screw is needed to lock the seat cushion 1 and the armrest 2, so that the assembly operation between the seat cushion 1 and the armrest 2 can be completed more quickly.
