Abstract
The utility model relates to a handrail with the adjustable force ratio. The handrail comprises an upper part of the handrail and a lower part of the handrail, and further comprises a gas spring, wherein the gas spring comprises a gas rod and a gas cylinder; the gas rod is connected with the upper part; the gas cylinder is connected with the lower part of the handrail. The handrail disclosed by the utility model adopts elastic restoring force of the gas spring as lifting force of the handrail, and utilizes naturally downward force of the elbows of people to balance the elastic restoring force, so that an arbitrary state can be realized while the handrail height is regulated, and therefore, the handrail not only is novel and various in forms and functions, but also can relatively easily attract the eyes of consumers. Moreover, the handrail is practical and comfortable, so that the market competitiveness of a product is greatly enhanced.
Description
Technical field
The utility model relates to a kind of handrail, the adjustable handrail of especially a kind of force rate.
Background technology
At present, the chair on market is varied, and corresponding handrail is also varied.And the ornamental utility function that is greater than of handrail often.Along with people are more and more higher for the pursuit of quality of the life, the handrail of adjustment height will be more and more welcome.So the adjusting of the height of handrail is not a new concept, the handrail that traditional height regulates adopts mechanical system to regulate often, be first adjustable handrail height, be transferred to correct position descendant and sit on chair, if people sits down, after sensation handrail height is improper must get up tune once again.For this problem, the inventor did once and improved, as the patent No. Chinese utility model patent that is 201020151559.1, he discloses a kind of hydraulic automatic armrest height regulation chair, it is by handrail, slideway, knob, upper bracket, seat, adjusting knob, column, oil pocket, pressure rings, lower carriage, base, oiling bolt, pressure rings baffle plate, lower baffle plate, stop pin, overhead gage forms, handrail is connected with upper bracket, upper bracket is fixed on lower carriage, pressure rings has a plurality of, lower carriage is sleeved in pressure rings, pressure rings baffle plate is equipped with in the upper end of lower carriage, pressure rings is sleeved in column.This patented technology is owing to adopting hydraulic regulation handrail height, and handrail height can adapt to people's sitting posture automatically, and keeps constant strength to support ancon weight, compares with traditional Chinese chair, more meets ergonomics.In this patented technology, also have some shortcomings, as unadjustable in force rate, the support force that hydraulic system can provide is constant, can not be conditioned; This will cause the scope of application of this patent chair limited, and as the chair of the high hydraulic coupling of under-weight people inconvenience use, the chair of low hydraulic coupling is used in people's inconvenience of high body weight.
Utility model content
The utility model will solve the problems of the technologies described above, thereby provides a kind of force rate adjustable handrail.
The technical scheme that the utility model addresses the above problem is as follows:
The handrail that force rate is adjustable, comprises handrail top and handrail bottom, also comprises air spring, and described air spring comprises gas bar and inflator, and described gas bar is connected with described handrail top, and described inflator is connected with described handrail bottom.
In the utility model technique scheme, inventor proposes following technical thought: utilize elastic-restoring force that air spring provides and people's elbow to reach the lift adjustment for handrail for the pressure equilibrium of forces of handrail.Air spring can provide stable restoring force, and no matter which kind of height handrail is maintained at.This is for the people who is sitting on chair, and the height of adjustable handrail is arbitrary, and regulates considerably comfortable.May there is people can ask such problem here, what kind of does is handrail in the time of handrail zero load? or even ask such problem, if people's elbow is the value of a variation for the pressure of handrail? unloaded for handrail, on chair nobody time, handrail will appear at its highest order, the lift of the handrail elastic-restoring force that namely air spring provides is offset by the limit function of air spring itself, and this is those of ordinary skills' conventional knowledge, therefore need to be in this fine elaboration.Variation issue for power, handrail lockout issue in use namely, conventionally the power that maintains air spring immediate status has a difference with the power that air spring generation state is changed, such as, the power that maintains air spring immediate status needs 3kg, the power that will make so air spring further compress may need 3.5kg, make the power of the further resilience of air spring may need lower than 2.5kg.This is a very general physical phenomenon.Such as a chest being become to the power that motion state needs 10kg from static, once after still pulling, the power that maintains chest motion state may only need 8kg.This is relevant with force of sliding friction with stiction to a great extent, and the characteristic of air spring is like this equally.It is that hydraulic cylinder is not available that air spring also has a characteristic, that is exactly that the power that provides of air spring is more soft, lifting as armrests is more comfortable, and it is also larger with the power deviation that changes state that it maintains state, in other words, when people is utilized to dynamic balance locking handrail height, there is a larger balance space.
Handrail described in the utility model top refers to that handrail is for setting off the part of elbow, and it can comprise the position being connected with other parts of handrail certainly.Handrail described in the utility model bottom refers to that handrail is for connecting the part of chair, and it can comprise the position being connected with other parts of handrail certainly.
As technique scheme preferably, also comprise air spring adjusting device, described air spring adjusting device comprises adjusting gas bar, regulates inflator and adjusting knob, described adjusting inflator is carved with the first screw thread, described adjusting knob is carved with the second screw thread matching with described the first screw thread, and described adjusting inflator is connected by described first and second threaded engagement with described adjusting knob; Described adjusting inflator also has a flue connector, and described inflator is connected with described flue connector by flue; Thereby realize the handrail lift that adjusting knob described in turn regulates described air spring.
In the utility model technique scheme, adopt the precession of screw thread regulate can realizable force ratio electrodeless adjusting.Electrodeless adjusting has the function of fine setting, and its amount trimmed is controlled by the precession amount of adjusting knob.
As technique scheme preferably, described handrail top is also connected by the handrail shell being set with mutually with handrail bottom.
As technique scheme preferably, on described adjusting inflator, be also carved with the handrail power rule that is used to indicate described adjusting knob precession amount.
The enforcement of the utility model technique scheme, make people can produce memory capability in use, such as when adjusting knob is selected in 3 scale, people just know that now the lift of handrail has much, if large, can regulate, and know it is that direction toward which scale regulates.Use convenient.
In sum, the utlity model has following technique effect:
1. the utility model has adopted the elastic-restoring force of air spring as the lift of handrail, utilize the naturally downward power of people's elbow to balance each other with it, thereby can show arbitrary state while reaching adjustable handrail height, not only novel and diversified on form function, more easily attract consumer's eyeball, and practical comfortable, greatly strengthened this competitiveness of product in market;
2. force rate of the present utility model can regulate, applied widely;
3. the utility model regulates force rate to have the function of electrodeless adjusting, and accurate trace regulates, and can reach more comfortable object.
