Abstract

A seat capable of meeting different sitting posture requirements is characterized in that the seat can be respectively arranged into structures of a common seat, a deck chair and the like by changing different seat surface positions and seat back positions so as to meet different sitting posture requirements.

Description

Multifunction seat

Technical field:

The present invention relates to a kind of furniture product, and the seat of different sitting postures especially can be provided.

Background technology:

At present, mostly existing furniture functions of seat is single, there are work chair, leisure chaise longue, office chair etc., can only meet a kind of requirement of sitting posture, both being the multifunction seat having, is also in the situation that a kind of sitting posture is constant, adjusts the height of seat surface or the angle of inclination of backrest, or the function that provides some to write etc. other, instead of provide diverse multiple sitting posture requirement.

Summary of the invention:

In order to increase the function of seat, the present invention designs a kind of seat.This seat, by conversion armchair structure, can be arranged to respectively the structure of common seat, leisure chaise longue, chaise longue, to adapt to diverse three kinds of sitting postures.

The front end of the chair top of the present invention's design is connected with curved bar by bearing pin, and the groove of chair top rear end is overlapped on the crossbeam of seat frame, and the lower end of backrest is connected with chair top rear end by bearing pin, and backrest is supported by back bracket.

In the time that chair top is placed in one way, the front end of Connection Block seat is connected on curved bar, the groove of chair top rear end is overlapped on a crossbeam of seat frame, chair top is surface height (seat surface leading edge) and the inclination of the seat surface of common sitting posture requirement, after backrest, supported by back bracket, backrest reaches the inclination angle of common sitting posture backrest, just becomes the armchair structure of common sitting posture.In the time that chair top is placed in another way, overturning seat seat, chair top front end is turned to a position with curved bar, the groove of chair top rear end is overlapped on another crossbeam of seat frame, chair top reaches surface height (seat surface leading edge) and the inclination of the seat surface of leisure sitting posture requirement, after backrest, supported by back bracket, just become a kind of armchair structure of the sitting posture that lies fallow.When changing the position of back bracket, backrest back rake angle is increased, just become the armchair structure of another kind of leisure sitting posture.

The beneficial effect of the seat of the present invention design is, can realize with a chair function of three kinds of seats, is convenient to people and adjusts rest, simple in structure, easy to operate.

Brief description of the drawings:

Below in conjunction with accompanying drawing, the present invention is further described with enforcement.

Fig. 1 is the structural map of seat of the present invention.

Fig. 2 is the structural map of seat frame.

Fig. 3 is the structural map of first embodiment of seat.

Fig. 4 is the structural map of second embodiment of seat.

Fig. 5 is the structural map of the 3rd embodiment of seat.

In figure, 1. backrest; 2. chair top; 3. seat frame; 4. bearing pin; 5. curved bar; 6. bearing pin; 7. bearing pin; 8. back bracket; 9. bearing pin; 10. bogie side frame; 11. crossbeams; 12. crossbeams; 13. crossbeams; 14. projections.

In Fig. 1, chair top 2 is mounted on one end of curved bar 5 by bearing pin 4, and the other end of curved bar 5 is mounted on seat frame 3 by bearing pin 6, and curved bar 5 can rotate and drive chair top to move around bearing pin 6.Backrest 1 is connected with chair top 2 by bearing pin 7.Back bracket 8 is arranged on seat frame 3 by bearing pin 9, can rotate around bearing pin.

In Fig. 2, crossbeam 11, crossbeam 12, crossbeam 13 and two body side frames 10 link into an integrated entity and form seat frame 3, and projection 14 connects on body side frame 10.

Detailed description of the invention:

In the embodiments of figure 3, the front end of chair top 2 is supported on curved bar 5, and the rear end groove of chair top 2 is overlapped on crossbeam 13, and seat surface has reached surface height (seat surface leading edge) and the inclination of the seat surface of common sitting posture requirement, as shown in Figure 3.Backrest 1 rests in back bracket 8, and the lower terminal block of back bracket 8, on projection 14, with stable chair backrest 1, ensures common sitting posture inclination of the seat backrest.People is sitting on chair top 2 with common sitting posture, and human body upper body leans against on backrest 1, and body side frame 10 is as armrest.

In the embodiment of Fig. 4, the rear end groove that lifts chair top 2 departs from crossbeam 13, and overturning seat seat 2 drives curved bar 5 to rotate around bearing pin 6 by bearing pin 4 forward, until curved bar 5 keeps off on crossbeam 11, the rear end groove of chair top 2 is overlapped on crossbeam 12.Seat surface has reached surface height (seat surface leading edge) and the inclination of the seat surface of leisure sitting posture requirement, as shown in Figure 4.Backrest 1 rests in back bracket 8, and the lower end of back bracket 8 leans against on projection 14, ensures common sitting posture inclination of the seat backrest to stablize backrest 1.People is sitting on chair top 2 with leisure sitting posture, and human body upper body leans against on backrest 1, and body side frame 10 is as armrest.

In the embodiment of Fig. 5, on the armchair structure basis in the embodiment of Fig. 4, invertible back support support 8 forward, backrest 1 rests in the back bracket 8 after upset, and the back rake angle of backrest increases, as shown in Figure 5.Reach the inclination of the seat backrest of chaise longue sitting posture requirement.People is sitting on chair top 2 with semi-lying sitting posture, and human body upper body lies on backrest 1, and body side frame 10 is as handrail.
