Abstract
The utility model relates to a folding chair support rack with an armrest. Four lateral faces are composed of X-shaped support racks (10). Two adjacent lateral faces are corresponding to the end head of a support rod, and two adjacent lateral faces are separately and pairwise hinged with the same hinge head to form a folding knee point. The utility model is characterized in that the front and the back both sides of the X-shaped support rack at the side of the support rack are respectively provided with a hold-up handrail support rod (9) and a pull-down handrail support rod (5), and the upper end of the hold-up handrail support rod is hinged with the front and back parts of a horizontal handrail (2). When the support rack is folded, the hold-up handrail support rod jacks up one end of the handrail, and the pull-down handrail support rod pulls down the other end of the handrail, so that the handrail can be folded erectly. The utility model is easy to fold and carry, and the middle part of the handrail has not the crack.
Description
The utility model belongs to a kind of folding seat bracing frame of Armrest.
Handrail also drew in together when the folding seat bracing frame of existing Armrest drew in for folding seat is folded, but handrail is formed by two sections of doubling usually, so the crease in the middle of when using crushes the people sometimes easily, and need just can impel its folding gathering in the special application of force in this position sometimes when folding.
The utility model aims to provide and a kind ofly can fold gathering, and the folding seat bracing frame of the Armrest of strap clamp seam not in the middle of the handrail.
The technical scheme that realizes above-mentioned purpose is: four sides of the present utility model are formed by the X-shaped support (10) that two support bar middle hinge form, corresponding support bar termination, adjacent two sides respectively in twos hinge in same hinge head (12,11,6,3) form folding flex point, backrest support rods (1) vertical to the back upper hinge head (3) that passes trailing flank with being slidingly matched, the lower end is connected with the back hinge head (6) down of trailing flank, it is characterized in that: both sides respectively are provided with a handrail support bar (9 before and after bracing frame beside X-shaped support, 5), two handrail post uppers respectively with level to handrail (2) preceding, the rear portion hinge connects, wherein a support bar is a drop-down handrail support bar (5), its middle part is connected with the last brace part hinge of respective side X-shaped support by sliding fiting sleeve sliding sleeve (4) thereon, the lower end is connected with the following brace part hinge of homonymy X-shaped support, another support bar is a last top handrail support bar (9), its middle part is connected with the last brace part hinge of respective side X-shaped support, the lower end be enclosed within this side X-shaped support with being slidingly matched under sliding sleeve (8) hinge on the brace be connected.
The utility model integrated support frame folds when drawing in, last top handrail support bar (9) can jack-up should be held horizontal handrail, the horizontal handrail of the corresponding other end of leaving behind of drop-down handrail support bar (5) meeting, thus level is erected to handrail (2), draw in whole bracing frame is folding.
The utility model is convenient to folding carrying, and its horizontal handrail is an integral body, and integral body erects when folding, and crack is not established in the centre, can not crush the people.
