The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of the utility model is not limited thereto.
Armrest as depicted in figs. 1 and 2, armrest comprises handrail bracing frame 18, handgrip pad assembly, adjustment bracing frame 8, fixture block 9, elastomeric element 10, fixed strip 11 and adjustment bracing frame lid 17; Handrail bracing frame 18 is fixed in said fixed strip 11 lower ends, and fixture block 9 is installed on the fixed strip 11, and an end of elastomeric element 10 is connected with fixture block 9; The other end is connected in fixed strip 11; Adjustment bracing frame 8 cooperates with adjustment bracing frame lid 17 and is enclosed within on the fixed strip 11, injects handrail bracing frame 18 simultaneously, and the handgrip pad assembly is installed on adjustment bracing frame 8 upper ends; Be provided with the tooth bar 16 that cooperates with fixture block 9 in the adjustment bracing frame 8, tooth bar 16 is towards the below of adjustment bracing frame 8.
Said tooth bar 16 is positioned at the inboard of adjustment bracing frame 8, the inner tooth bar 9 of adjustment bracing frame 8 bottom tooth below exist fixture block 9 to be used to reset first cavity 21, tooth bar 16 is the top of teeth second cavity 22 that exists fixture block 9 to be used to reset topmost.
The number of the teeth groove that said tooth bar 16 cooperates with fixture block 9 is 5.
The middle part of said fixed strip 11 is provided with rotating shaft 13 and the boss with fixed strip 11 one, and boss is positioned at the below of rotating shaft, and boss is provided with first hole 12.
Said fixture block 9 centers are provided with a through hole 14, and through hole 14 is passed in rotating shaft 13, and an end of fixture block 9 is provided with second hole 15.
Said elastomeric element 10 is a torsion spring, and fixture block 9 and torsion spring are installed on the rotating shaft 13 of fixed strip 11 successively, and an end of torsion spring inserts second hole 15, and the other end inserts first hole 12.
Said adjustment bracing frame 8 upper ends are provided with rectangle nut seat 7.
Said handgrip pad assembly comprises the fixed block 5 and the handgrip pad lower cover 6 of handgrip pad 1, lock screw 2, circular arc plush copper 3, spring 4, band circle-arc tooth position 51; Spring 4 heads on circular arc plush copper 3; The circle-arc tooth position 51 that circular arc plush copper 3 is inserted fixed block 5; Lock screw 2 passes fixed block 5 successively, handgrip pad lower cover 6 is screwed into the nut seat 7 of adjusting bracing frame 8, and handgrip pad 1 is installed on handgrip pad lower cover 6, and fixed block 5 is fixed on the nut seat 7.
Said handgrip pad lower cover 6 is provided with the groove of laying spring 4 and fixed block 5.
The lower end of said handrail bracing frame 18 is installed on Chair underframe 19, and backrest 20 is fixed in the upper end of handrail bracing frame 18.This setting can make armrest carry out synchronous elevation angle adjustment with backrest.
The lifting process of handrail is: fixed strip is fixed in the handrail bracing frame, and can't move.As shown in Figure 2, when handrail was positioned at lowest part, fixture block was positioned at second cavity; Fixture block only receives the active force of torsion spring; Be in the state of stress balance, the end that fixture block cooperates with teeth groove is downward-sloping, when upwards spurring the adjustment bracing frame with hand; Fixture block will receive the barrier force of tooth bar to it, and fixture block will be that the center clockwise rotates with the rotating shaft on the fixed strip.When fixture block forwarded certain angle to, fixture block received the active force of torsion spring, and the direction of motion of fixture block will be from changing into counterclockwise clockwise; First teeth groove of end entering of fixture block is cooperated; Stop the upwards pulling to the adjustment bracing frame this moment, because of locking between fixture block and teeth groove, handrail can only move upward; And can't descend, even handrail is fixed on certain height (as shown in Figure 3).Below four grooves, the motion process of fixture block is the same with first groove, and is different according to everyone figure, pushing degree; Upwards bracing frame is adjusted in pulling; The teeth groove of fixture block and differing heights is locked, make handrail be fixed in the different height position, improved comfort level.When wanting handrail to fall back to lowest part, upwards spur the adjustment bracing frame with hand, make handrail peak, boss withstands the inwall of adjustment bracing frame, and handrail can't move upward again.At this moment; Fixture block is positioned at the first cavity place, and fixture block no longer receives the active force of tooth bar, only receives the active force of torsion spring; Make fixture block to rotating counterclockwise; The end that fixture block is cooperated with teeth groove downward-sloping (as shown in Figure 4), promptly the state of the replying state of fixture block when being positioned at lowest part with handrail is the same, and fixture block is in the state of stress balance.Again the adjustment bracing frame is applied downward active force; Tooth bar has the downward active force and the reset force of torsion spring to fixture block; Make fixture block have being rotated counterclockwise the alternating movement with clockwise rotation, make fixture block and tooth bar that the sound of bump arranged, last handrail drops to lowest part.
The rotary course of the handgrip pad assembly of handrail: fixed block is motionless, and second spring heads on the circular arc plush copper, and the circular arc plush copper is inserted the circle-arc tooth position of fixed block, and hand-screw is changed hands pad and handgrip pad lower cover.The angle of rotation can design according to the number of teeth of circle-arc tooth position.
The above-mentioned specific embodiment is the preferred embodiment of the utility model; Can not limit the utility model; Other any change or other equivalent substitute mode that does not deviate from the technical scheme of the utility model and made is included within the protection domain of the utility model.
