Abstract
The invention relates to a self-locking lifting desk for standing and sitting, which aims to enable office workers and computer operators to conveniently change standing and sitting postures. The self-locking lifting desk for standing and sitting is characterized by comprising a desk, a lifting mechanism and a heavy object balancing mechanism, and further comprising a self-locking mechanism. The self-locking lifting desk for standing and sitting of the invention is used in a way that: the A end of a lever in the self-locking mechanism is pedaled down with a foot and the desk on a platform of the lifting mechanism can be vertically lifted; and when the foot leaves the lever, the self-locking mechanism locks the lifting mechanism, so that the platform and the desk cannot be descended. Compared with the prior art, the self-locking lifting desk for standing and sitting has the characteristics of high lifting speed and low cost because the heavy object balancing mechanism adopts flexible cords, rollers and a counter weight, and low running noise and suitability for the quiet environment of workplaces because the flexible cords are used for towing the counter weight.
Description
Affiliated technical field
The invention belongs to the office furniture technical field, particularly a kind of liftable desk.
Background technology
Modern offices generally is provided with the desk or the workbench of supporting computer, printer, file, and operating personnel are sitting in the preceding operation of computer for a long time, can cause the disease such as cervical spondylopathy, sciatica.Medical experts advise that these operating personnel should often change the attitude of seat, to avoid the generation of above-mentioned disease.But because work strain, these operating personnel are difficult to find time stand up and relax.Can operating computer if can stand up also, be to kill two birds with one stone, just work delays has neither changed long-time seated posture again.
The patent No. of the John J.Rizzi that on March 1st, 1994 announced etc. is 5,289,782 United States Patent (USP)s, a kind of height-adjustable desk (as shown in figure 10) is disclosed, its desktop 51 is an one with outer table leg 52, on the table leg 53, regulates desktop 51 height with this in outer table leg 52 is enclosed within.Adopt the gravitational equilibrium mechanism (not shown) to make the lifting desktop effortlessly.But what gravitational equilibrium mechanism adopted is parts such as tooth bar, pinion, chain, therefore because its complicated structure makes product comparatively expensive.The shortcoming of next is that the speed of adjusting height of table top is slower, and operating personnel want to change posture, if the adjustment process trouble will not thought to have changed height of table top again.In addition, the patented product is in the process of regulating height, because the running noises of tooth bar, pinion and chain has destroyed the quiet environment in office space, so this desk is not extensive use of so far as yet.
Summary of the invention
In order to address the above problem, it is very fast to the purpose of this invention is to provide a kind of speed of regulating desktop height, the lifting desktop effortlessly, the lifting table that cost is lower, and noise is also very little when regulating height, the posture that makes clerical workforce and computer operater change easily or sit or stand.
The present invention is achieved in that it comprises desk, elevating mechanism and weight balanced controls, has also comprised self-locking mechanism;
Described self-locking mechanism mainly is made of roller, contract seat, push rod and lever, and wherein, roller is arranged in the contract seam that the extension of contract seat and elevating mechanism forms, and can form self-locking state; Lever and push rod are hinged, and lever and fulcrum are hinged; When the motion down of the A of lever end, then the B of lever end upwards promotes push rod and roller and moves upward;
Described weight balanced controls mainly by heavily hang down, tightrope, upper roller and bottom roller constitute, wherein an end of tightrope is connected with the following rolling shaft of elevating mechanism, the other end and heavy vertical connection, interlude is walked around bottom roller and upper roller;
Described desk is arranged on the platform of elevating mechanism.
Described tightrope is a nylon rope.
The platform in the described elevating mechanism and the weight sum of the load on the platform thereof are greater than the weight of heavily hanging down.
Using method of the present invention: with the lever A end in the foot-operated self-locking mechanism down, the desk on the elevating mechanism platform can vertical lift; After pin left lever, self-locking mechanism pinned elevating mechanism, and platform and desk can not be descended.
The present invention's characteristics compared with prior art are: because gravitational equilibrium mechanism adopts tightrope, roller and heavily vertical, so rising or falling speed is fast, cost is low, and heavily vertical with the tightrope traction, and noise is low during operation, the quiet environment of very suitable office space.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
In order to understand the present invention easily, the kinematic sketch according to Fig. 8 and Fig. 9 describes earlier.Lowering or hoisting gear of the present invention increases self-locking mechanism 2 on the basis of traditional elevating mechanism 1, weight balanced controls 3 have also been done improvement.
Using method is: (see figure 8) is with the A end of the lever 24 in the foot-operated self-locking mechanism 2 down, and the roller 21 in the self-locking mechanism 2 is lifted (see figure 9), and self-locking state is removed, and then the platform 13 in the elevating mechanism 1 can vertical lift; After pin left lever 24, the roller 21 in the self-locking mechanism 2 compressed extension 11 in the elevating mechanism 1 (extension 11 is fixed as one with platform 13), and promptly self-locking mechanism pins elevating mechanism, made platform 13 (see figure 8) that can not descend.
Self-locking mechanism mainly is made of roller 21, contract seat 22, push rod 23 and lever 24, and wherein, roller 21 is arranged on the contract of extension 11 formation of contract seat 22 and elevating mechanism and stitches in 25, and extension 11 is compressed.Balance by roller can be known by inference, and its condition of self-locking is
α is the angle of contract seam 25,
With
Be respectively the angle of friction of 11 of roller 21 and contract face 27 and extensions.α can process very for a short time, so a little condition is met easily, roller promptly is self-locking state after falling into contract seam 25, can only descend and can not rise.If elevating mechanism and extension 11 thereof are towards lower slider, roller 21 also can roll thereupon down, and roller is pressed the extension tighter as a result, and promptly the platform 13 of elevating mechanism can not move down, forms self-locking state.Lever 24 is hinged with push rod 23, and lever 24 is hinged with fulcrum 26; When the A of lever 24 end by down foot-operated, then the B of lever end upwards promotes push rod 23 and roller 21 and moves upward, roller no longer compresses extension 11, then the platform 13 in the elevating mechanism 1 can vertical lift (see figure 9).
In order to mention the desk on platform 13 and the platform easily, be provided with weight balanced controls 3.Weight balanced controls 3 mainly by heavily hang down 31, tightrope 32, upper roller 33 and bottom roller 34 constitute, wherein an end of tightrope 32 is connected with the following rolling shaft 12 of elevating mechanism, the other end with heavily vertical 31 be connected, interlude is walked around bottom roller 34 and upper roller 33.Described tightrope 32 is preferably nylon rope.Heavily hang down 31 by tightrope 32, to the Zola, make platform 13 obtain a power that makes progress the following rolling shaft 12 in the elevating mechanism 1.The platform 13 in the elevating mechanism and the weight of the load on the platform thereof should be greater than the weight of heavily hanging down, otherwise are difficult to produce self-locking (above-mentioned load is the article on desk and the desk thereof).Because heavily vertical weight is so as long as make very little power, just can mention the load on platform 13 and the platform thereof.Tightrope and roller in service has only very little noise, and this is one of advantage of the present invention.
