Description

The armchair structure that a kind of seat support can delay

Affiliated technical field

The utility model relates to a kind of structural design category that is used for row's seat support chair of using public places such as assembly hall, cinema, music hall, Conference Hall, specifically, relates to the design category of the armchair structure that a kind of seat support can delay.

Background technology

At row's chair of public places such as assembly hall, cinema, music hall, Conference Hall, its seat support normally overturns, and during use seat support is put down, and erects at time spent self-return not, enlarges passage, evacuates in order to spectators.The seat support of row's seat support chair reaches user mode from collapsed state to be realized by manually reaching body weight, seat support from user mode reach collapsed state then need by various settings make seat support from, for example the rear portion in the seat support frame is provided with balance weight iron, the center of gravity of seat support is moved to the turning cylinder rear side, thereby make seat support from, utilize in addition the twisting resistance of torsion spring make seat support from, its ubiquitous shortcoming is that the seat support speed of gyration is too fast, can send impact sound when striking other when spacing, thereby the auditory effect in place is used in influence.For solving this defective, adopt the air spring of in the seat support frame of row's chair, settling a damping both at home and abroad, utilize the damping action of air spring, when being packed up, seat support slowly returns back to spacing position, to reach the purpose of collisionless sound.Yet, utilize the slow row of the standing up chair of damping air spring to be prone to the inconsistent phenomenon of seat support return, cause the seat support front and back uneven, the overall appearance of influence row chair.Its reason mainly is that the push rod of damping air spring is flexible under power effect by bending for a long time, and the frictional resistance that piston moves in cylinder strengthens, and seat support can't be rotated by the frictional resistance effect and returns back to spacing position.Or damping air spring seal is on the piston of air spring, and piston is a movable part, and the frequent friction of seal and air spring is worn and torn gradually, influences the service life of seat.

The purpose of this utility model is the armchair structure that a kind of seat support of design can delay, and solves the sound and resilience vibration problems of seat seat support return, the service life that also can improve armchair structure simultaneously.

The utility model content

Below in conjunction with accompanying drawing the realization the technical solution of the utility model is described:

The armchair structure that seat support can delay mainly contains the chair back [1], armrest of seat [2], seat support [3], chair frame body [4] and chair leftover bits and pieces [5] (are seen Fig. 1, Fig. 2, Fig. 3), characteristics are that chair frame body [4] structure is by chair support [6], damper [7], damper frame [8], seat support supporting plate [9], seat support bent axle [9A], chair back plug-in unit [10], leaf spring [11], pedestal [12] composition (is seen Fig. 4, Fig. 5, Fig. 6, Fig. 7), chair support [6] is approximate U type for section and has the hardware of trough rim, anterior inboard is provided with leaf spring [11], it is connected with the chair support with bolt (sees Fig. 5, Fig. 7), the carriage [8A] that damper [7] is arranged in chair support [6] the anterior outside damper frame [8] upward (is seen Fig. 4, Fig. 6, Figure 14), be provided with the pedestal [1 2] that both sides have groove at chair support [6] nock and (see Fig. 5, Fig. 8), chair support [6] rear upper end inboard is provided with the seat support supporting plate locating part [6A] that section is the L type, top, chair support [6] rear portion is connected with chair back plug-in unit [10] (sees Fig. 4, Fig. 5), seat support supporting plate [9] outer appearnce is like soft-shelled turtle shape (seeing Figure 11), below seat support supporting plate [9], be provided with seat support bent axle [9A], the square shaft [9B] (see Figure 12) of one end of seat support bent axle [9A] for being connected with damper, the spacing cushion pad [9C] that is provided with rubber mass at seat support supporting plate [9] one ends (is seen Figure 10, Figure 11, Figure 12), seat support supporting plate [9] is provided with fluted body pedestal [12] by its seat support bent axle [9A] with chair support [6] nock both sides and is connected, leaf spring [11] is buckled in the protruding part of seat support bent axle [9A] simultaneously, under the seat user mode, the spacing cushion pad [9C] of seat support supporting plate [9] rear end just in time pushes up on the seat support supporting plate locating part [6A].After the seat seat support used end, under the acting in conjunction of leaf spring and damper, seat support slowly returned to return state (see figure 3).

Adopt row's chair that armchair structure that the seat support of the utility model design can delay and seat support are equipped with the damping air spring to compare and also have following remarkable advantage:

1, the seat seat support is noiseless when return, and return puts in place, and the row's of making chair integral body is neat, attractive in appearance;

2, the upset of seat seat support is to finish by the pedestal and the seat support bent axle that are arranged on the chair frame body, is arranged on the more succinct easy to clean of chair base structure on the arm-rest frame with pedestal;

3, the overall structure performance of seat seat support is good, can improve its service life.
