Description

Adjustable working chair

The utility model is a kind ofly can protect the healthy seat operating and increase work efficiency be convenient to again of operating personnel.

Along with the develop rapidly of science and technology, the mode that people are engaged in productive labor is changed to " intensity " by " intensity type ", and light physical labor and mental labour ratio constantly increase, and increasing work is finished in the seat mode.According to statistics, developed country's seat operation number has accounted for whole practitioners' 3/4.Therefore, many countries attach great importance to the research of seat operation to the health influence.Its result shows that the seat design of science not only can reduce the harmful effect of seat operation to human body, but also can improve people's work capacity and operating efficiency.According to the industry survey based on the seat operation such as China's electronics, machinery, light industry, clothes, the seat that uses in current China industrial production is of a great variety, select for use randomness very big, mainly be subjected to factor affecting such as time buying, place, economic conditions, manufacturer and product batches, less consideration job specification and user's characteristics.Seat is selected for use very lack of standardizationly as a result, very causes same enterprise, workshop or production line, and the seat that the identical mode of production is used is also of all kinds.The workman is very poor to the evaluation of seat, is prone to the soreness of waist, lumbago shape after most reflections are used, and is difficult for alleviating after rest.

Problem at above-mentioned prior art existence; to be exactly that design is a kind of both helped protecting that the operating personnel's is healthy to the purpose of this utility model; the Work seat of being convenient to production operation again and increasing work efficiency uses with the personnel that are applicable to sitting posture operation in production or the work.

Work seat of the present utility model is to be the support (1) of five-pointed star castor by the bottom, by seat plane (4) and a seat part that high adjustable screw (2) is formed, with by waist by framework (12), extension spring (11), support plate (10), holddown spring (9) regulating handle (8), the outer skin of waist (14) leans on (5) with the waist that cushion course (13) is formed, and the lower end tightens up by set lever (3) and connects with the sleeve pipe (17) of seat bottom surface, plane (4), top and internal layer tight fit have soft tooth cover (16) and be fixed on waist leans on the waist of support (6) composition to constitute by part by the joining waist of sliding sleeve (7) on the back plate (15), and the seat of comfortable sitting posture, its main design size (as shown in Figure 1): a≤250mm, b≤450mm (adjustable), c≤300mm(is adjustable), d≤450mm(is adjustable) be advisable.

Below in conjunction with the described embodiment of accompanying drawing, be further described.

Accompanying drawing 1 is the utility model Work seat structure diagram

Accompanying drawing 2, for the waist of the utility model Work seat by structure diagram

Accompanying drawing 3 is for the utility model Work seat waist leans on partial sectional view

Accompanying drawing 4,5 is for the utility model Work seat waist leans on the shift sleeve structure schematic diagram

The utility model multidimensional adjustable type Work seat can be moved arbitrarily in level reposefully by the five-pointed star castor supporting of support (1) bottom.The seat high adjustable screw (2) that seat plane (4) bottom surface central authorities are fixedly connected can be regulated the height at seat and a plane (4) is freely rotated in horizontal plane, to reach the needs (Fig. 1) that adapt to various operations.

Sleeve pipe (17) fixedly is equipped with in seat bottom surface, plane (4), waist matches with sleeve pipe (17) by the lower end of support (6), and connect through screw-threaded coupling by set lever (3), by the front and back position of mobile waist by support (6) lower end and sleeve pipe (17), reach the dark purpose of adjustment seat, use (Fig. 1) with the people who adapts to different builds.

Waist links by support (6) with waist by two sliding sleeves (7) up and down by (5), because waist is little by (5) weight, and only bears the active force of horizontal direction, therefore need utilize frictional force that it can be fixed, and is not only easy to adjust but also simple in structure.Sliding sleeve (7) is stamped to form by iron plate, and the centre is surrounded by the flexible plastic tooth cover (16) of a band internal tooth, also available elastomeric material.It is tight fit (Fig. 4,5) that tooth cover (16) and waist lean between support (6).Sliding sleeve (7) is fixed on waist by screw and goes up (Fig. 2) by back plate (15).Waist moves up and down by support (6) top at waist by sliding sleeve (7) by (5), to regulate waist adapts to different statures by the height and position of (5) people's use.

Waist by framework (12) trailing flank through screw be fixedly connected waist lean on after plate (15), (15) center is a screwed hole, the regulating handle (8) that has screw rod matches with this screwed hole, passing waist leans on the screw portion of back plate (15) to be set with holddown spring (9), the boss at support plate (10) center of being equipped with by framework (12) leading flank with waist makes holddown spring (9) location jointly, support plate (10) is made by steel spring plate, the two ends of extension spring (11) are separately fixed at waist by on framework (12) and the support plate (10), (12) and (10) are linked, waist has foamed plastics bed course (13), surface to be surrounded by artificial leather epidermis (14) (Fig. 2 by (5) outer illiteracy, 3).Waist can be regulated by regulating handle (8) by the protruding radian of (5), to adapt to the shape of different human body lumbar vertebrae.When regulating, rotate regulating handle (8), can make screw rod waist by the screwed hole at plate (15) center, back in precession or back-out, adjust the tight power of giving of holddown spring (9), when spring (9) is pressed on the support plate (10), (10) strengthen by the pretightning force between the framework (12) through extension spring (11) and waist, it is big that support plate (10) radian becomes, and giving tight power, to get over the projection of big bear plate (10) just big more.Otherwise it is then more little.

Relevant size a, b, c, the d of Work seat among Fig. 1 are definite according to the requirement of human comfort sitting posture, a≤250mm wherein, b≤450mm(is adjustable), c≤300mm(is adjustable), d≤450mm(is adjustable).Above-mentioned size and adjustable range thereof can be suitable for the adult men and women of China more than 90% and use.

The utility model adjustable working chair is simple and reasonable; and be easy to make and use; compared with the prior art not only the height at seat and horizontal level are adjustable; and the front and back leaned on of waist, can regulate with radian up and down; therefore can become according to different work personnel's different statures, build, lumbar vertebrae situation adjusting seat and be fit to the healthy comfortable state of worker fully, not only can protect the purpose that the operating personnel is healthy but also can reach convenient operation and increase work efficiency. Above-mentioned Work seat is suitable for the adult of China more than 90% to be used. Has the value that extensive use is promoted. Obvious social and economic benefits is arranged.
