Abstract

A sitting alleviator for a chair comprises front connecting pieces which can enable a seat cushion to be pivoted and fixedly connected between two sides of the front end of a base, and backrest supporting units which can enable the seat cushion to be pivoted and fixedly connected between two sides of the rear end of the base, wherein an elasticity reliever is arranged at the fixed pivoting part of the seat cushion and the backrest supporting units, so that a fixed pivoting part which pivots the seat cushion and each backrest supporting unit by penetrating through a pivoted rod is arranged at each part where the seat cushion corresponds to each backrest supporting unit, alleviating spaces of larger fixed pivoting holes which can enable the pivoted rods to penetrate through and shift are arranged at fixed pivoting parts on the backrest, and simultaneously torsion springs of the fixed pivoting parts, which can elastically prop against corresponding parts at two ends are sheathed on the pivoted rods, so that compressing force instantly generated when a user sits on the seat cushion can be alleviated by the alleviating spaces and the elasticity supporting action of the torsion springs, and further the user can feel soft and comfortable rather than inflexible when sitting on the seat cushion.

Description

The chair tool take reliever

Technical field

A kind of buffer unit when the utility model relates to a chair tool and taking mainly is to make the rear end joining place of cushion be provided with a flexible cushion space, allows the moment of occupant feel more soft, comfortable and not stiff.

Background technology

Take the cushion position about our known chair tool, except being coated with elasticity in itself pad the soft foaming body, more pass through the elastic buffer effect of the air pressure rod at support cushion position, when allowing the occupant be seated on the cushion, can feel can be too not stiff and flexible.

But, the foaming body of above-mentioned cushion and air pressure rod, comfort when taking no doubt can be provided, but this cushion or air pressure rod can't be when the occupant be seated in moment, the compressing power that is produced, reach and have real abirritation, when allowing the occupant be seated on the cushion and stiff, uncomfortable sensation is arranged.

In addition, also have as shown in Figure 1 and Figure 2, the air pressure rod upper end of this chair tool connects establishes base 2, and before articulating one, the front end both sides of base 2 connect part 3, the upper end pivot that connects part 3 again before the order is fixed on the pin fixed part 12 of cushion front side, the rear end both sides of base 2 then articulate a chair back supporter 4, and in base 2, be equiped with the spring (not shown), and the effect that spring is pushed the generation elasticity of this chair back supporter 4, and then make the corresponding position of cushion 1 and chair back supporter 4 rear sides, and be respectively equipped with by hinged arm 5 pivots together pin fixed

part

11,41 admittedly.

So, when the occupant is seated on the cushion 1, the rear end of cushion 1 can be subjected to the elasticity of spring to push effect by chair back supporter 4, and the ability of generation elastic buffer, its main purpose is when allowing the occupant rest on the chair back 7, has the effect that elasticity leans on, though also allowing, above-mentioned spring takes the effect that on cushion 1, has buffering, this spring is the structure that belongs to thicker and hard, be suitable for holding the heavier weight of load, but hard comparatively partially, thus the moment of occupant on cushion 1 can't obtain real soft comfortable flexibility effect at all.

But, the elasticity dependence effect that above-mentioned this spring is produced the chair back 7 all is the state that is in locking usually, only when taking on the chair tool, just can discharge its locking, so when the elasticity dependence effect of the chair back 7 was locked, its cushion 1 did not just have the effect of taking power that relaxes.

The utility model content

Edge is, the moment of being taken for the cushion that improves aforementioned chair tool, can't allow the occupant feel soft problem such as comfortable, the utility model be the pin fixed part between cushion rear end and chair back supporter be provided with one can cushion the compressing strength the elastic moderation space, moment power and can being cushioned when allowing occupant, and then have elasticity and the soft comfortable effect of taking.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of chair tool take reliever, it is characterized in that, comprise that each pivot of forward and backward both sides of a base connects the chair back supporter of part and the reclining of tool elasticity before intrinsic, establish again a cushion forward and backward and each corresponding position before connect part and chair back supporter and articulate, form the framework that a class is four limit row, wherein the articulated section of this cushion and chair back supporter rear side is provided with one and can supplies the slow elastic moderation device that falls of cushion.

Wherein this elastic moderation device is included in and offers a pin fixed part with pivoted hole of larger aperture on the chair back supporter, and the corresponding position of cushion also is provided with pin fixed part, on two pin fixed parts, wear one then and be arranged with the hinged arm of torque spring, and the bipod of torque spring is resisted against on the pin fixed part of each corresponding position respectively powerfully.

The beneficial effects of the utility model are, by above-mentioned elastic moderation device set between cushion and chair back supporter, allow cushion itself just have the slow effect of falling of elasticity, so moment power when the occupant is seated on the cushion, can be subjected to the buffering of elastic moderation device, and then allow the occupant can not feel stiff discomfort and the comfortable effect of flexible softness.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified, wherein:

Fig. 4 is a side schematic view of the present utility model.

Fig. 5 is the B-B cross-section cutaway view of Fig. 4.

Fig. 6 is the local enlarged diagram in C place of Fig. 4.

Among the figure: 1. cushion, 11. pin fixed parts, 2. base 3. before connects part, 4. chair back supporter, 41. pin fixed parts, the solid hole of 42. pivots, 43. locating holes, 5. hinged arm, 6. torque spring, 61. pin, the 7. chair back.

The specific embodiment

See also Fig. 3, Fig. 4 and shown in Figure 5, the utility model is mainly to be that the cushion 1 of chair tool is to be arranged at a base 2 tops, and before making cushion 1 and base 2, connecting part 3 before establishing respectively between the rear side is linked to therebetween with 4 pivot joints of chair back supporter, and then shape is made a class and is tetragonal framework, wherein the articulated section between cushion 1 and chair back supporter 4 rear sides then is provided with the elastic moderation device, and this elastic moderation device is to comprise making this cushion 1 be respectively equipped with pin fixed part 11 with chair back supporter 4 corresponding positions, 41, and make two pin fixed parts 11, establish between 41 with a hinged arm 5 and be arranged in therebetween, with both pivots admittedly together, and the pivot that supplies hinged arm 5 to wear that makes this pin fixed part 41 is consolidated the aperture in hole 42, than external diameter greater than hinged arm 5, allow hinged arm 5 can in the solid hole 42 of pivot, do the displacement of preset range, make again simultaneously and be arranged with a torque spring 6 on this hinged arm 5 again, and make the bipod 61 of this torque spring 6, be resisted against respectively in the locating hole 43 set on the outside of pin fixed part 11 of corresponding position and the pin fixed part 41 strong elastic.

Therefore, please cooperate shown in Figure 6 again, when the occupant is seated on the cushion 1, moment can produce the power of compressing to cushion 1, enable pass is crossed this cushion 1 and chair back supporter 4 rear sides articulated section between the two, make hinged arm 5 displacement space that relaxes be arranged in the solid hole 42 of pivot, and under the resiliency supported of torque spring 6, allow above-mentioned displacement rubber-like cushioning effect, so the compressing power when cushion 1 is taken in order, can be subjected to soft and buffering effect that relax, even cushion 1 has the slow effect of falling of elasticity, even the moment of occupant, can feel the comfort of elastomeric flexible.
