Description

A kind of handrail lifting structure

Skill this area

The utility model relates to furniture, particularly a kind of handrail lifting structure, it utilizes clamping rod and the relative displacement of stopper plate, at this locating part when primary importance is moved to the second place, locating part can break away from the adjustment groove fully, and reaches the purpose of its rapid adjustment handrail height.

Background technology

By original Wooden chair, the structural development of chair has produced the adjustment design of automatic air pressure formula so far, give the many facilities of people and comfortable, adjust function just and in the design of armrests, also and then have, as Taiwan patent announcement in the annex one number No. 361168 " improvement of handrail lifting structure ", it mainly utilizes one to adjust the slip that seat 2 and one holder 1 produces the adjustment function, wherein be equipped with one between adjustment seat 2 and the holder 1 and push up pull piece 3 and holder 1 generation stopper, and the pull side of piece 3 of this top is subjected to replacing of a spring 6, the top then is subjected to replacing of a shell fragment 4, and a spacer 5 is covered on the pull top of piece 3 and shell fragment 4, top, make the top piece 3 of pulling be placed in by the locking of a screw 7 and adjust between seat 2 and the holder 1, and produce the Elastic Sliding location with clamping groove 12 in the chute 13 of holder 1, its more can by the change of shell fragment 4 angles location live the top pull piece 3 and on screw 7 in two ora terminalis of holder 1 upper hopper chute 13, adjust that seat 2 can be free to slide and the clip location that can not be subjected to screw 7 and reach.

Though this scheme can reach the adjustment function of its expection, but but still have many defectives on the implementation, this structure is pulled on the top and is assembled difficulty between piece 3 and the spring 6, and must be in large quantities in each member ccontaining each relative member of processing and locking, form the waste of manufacturing cost, and too much comparatively scattered between relative to each other of member, cause structural strength degree of subtracting, moreover member too much also produces fault, forms to adjust the uncertain of action, is sizable defective on its structure.

Moreover, the structure utilization and the fit on of this scheme are all too complicated, pull piece 3 of You Yiding is comparatively difficult with spring 6 and shell fragment 4 fit ons, the related assemble ability that influences integral body is on the low side, among the structure that hence one can see that because the design harmful effect of solid memder integrated operation and the usefulness implemented, necessity of its improvement is arranged in fact.

In addition, Taiwan patent announcement number No. 351966 " armrest structure (four) " in the annex two, it mainly utilizes being pivoted of spring 22, elasticity pushes the mode of clamping block 5, reach handrail height and adjust function, though this scheme can reach the adjustment function of its expection, but but still have many defectives on the implementation, structurally comparatively withered and fallen, and deviate to adjust seat quite easily or produce displacement, but a spring makes clip more uncertain, moreover, utilization of the structure of this patent case and fit on are all too complicated, and relative member is more difficult at assembling process, and the related assemble ability that influences integral body is on the low side.

In view of this, the applicant is for addressing this problem, be to be determined to be engaged in the many years of experience that furniture already designs, makes and researches and develops with it, expect and to create practical utility model, finally well-designedly after repeatedly exploitation improvement go out handrail lifting structure of the present utility model, it is by clamping rod and the relative displacement of stopper plate, at this locating part when primary importance is moved to the second place, locating part can break away from the adjustment groove fully, and reaches the operation of its rapid adjustment handrail height.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of handrail lifting structure that overcomes above-mentioned defective, utilize clamping rod and the relative displacement of stopper plate, at this locating part when primary importance is moved to the second place, locating part can break away from the adjustment groove fully, and reaches the purpose of its rapid adjustment handrail height.

For this reason, the utility model includes a kind of handrail lifting structure, includes:

One adjusts seat, its tool first end and second end, and be provided with the adjustment groove in the adjustment seat, wherein second end can be fixedly arranged on the seat both sides;

One handrail, it is provided with a storage tank between two ends up and down, and this handrail is placed in sliding type and adjusts in the seat;

One clamping rod, it is in conjunction with in the fixed armrest storage tank, and can produce relative slippage with handrail;

At least two locating parts, it is fixedly arranged on above-mentioned accommodation space and adjusts between the groove, and at primary importance and second place intercropping one displacement movement;

This locating part can be moved to the second place from primary importance, and makes locating part can break away from the adjustment groove fully.

Wherein handrail one end can set firmly an armrest pad.

Wherein the handrail other end is provided with a hook part, and a spring one end colludes is located at this, and the other end colludes establishes clamping rod one end, and clamping rod has the multiple Hui Li of an elasticity in storage tank.

Wherein be provided with the limited block in order to the backstop clamping rod of two correspondences in the handrail storage tank.

Wherein be provided with two perforation in the storage tank in order to ccontaining locating part.

Wherein locating part can be steel ball.

Wherein adjusting a semicircular cylinder by two symmetries is constituted.

Wherein adjusting groove is the semicircle arcuation.

Wherein adjust seat and can be inserted in the mobile jib, and can produce the pivot pendulum of relative special angle.

Can summarize with regard to the above and the utlity model has following advantage:

1, handrail lifting structure of the present utility model, when the user desires to increase handrail height, can directly upwards pull the tension and compression part, the tension and compression part also drives clamping rod when rising and do a motion to top offset in the storage tank of clip plate, and make the armrest pad and the handrail that set firmly with it also be driven rising simultaneously, when so handrail rises, promptly produce to be pulled and have upwards strength, so the hook of its clamping rod and hook part produce relative displacement and make spring produce the elastic force diastole, the interior limited block of this moment fixture and storage tank produces relative displacement, and make locating part by the perforation of handrail and adjust position between the groove, be moved to the perforation of handrail fully, adjust groove and break away from, and can reach the operator of its rapid adjustment handrail height, so the utility model operation quite simply has suitable practicality.

2, handrail lifting structure of the present utility model, utilize clamping rod and the relative displacement of stopper plate, this locating part is when primary importance is moved to the second place, locating part can break away from the adjustment groove fully, and reach the operation purpose of its rapid adjustment handrail height, and its structure is quite simplified, save the cost of many members and assembling, more convenient its is fabricated onto the process of assembling, the utility model that quite has economic benefit and industry applications, no matter it is all having its progressive on cost or on the structure, and solve the trouble and the inconvenience of known technology in the past.
