Description

A kind of Collapsible seat

Technical field

The utility model relates to the design of Collapsible seat, is specifically related to the Collapsible seat that a kind of seat can reverse upset.

Background technology

Disclose the Collapsible seat of various ways in the patent documentation and the market, integrated, its folding mode has 2 kinds, and a kind of is to utilize mode such as hinged that the seat front end is upwards turned over; Also having a kind of is to utilize the torsion spring applied force to make seat automatically revert to folded state, reaches folding effect, also is that the seat front end is upwards turned over when folding.These 2 kinds of folding seat press down by the seat front end application of force is past in use, reach the user mode that the seat expansion is taken a seat.The shortcoming of this 2 class folding seat is: (1), seat front end are upwards turned over, the non-use face when making normal the use, and promptly the seat back side is exposed outside, and is not attractive in appearance; (2), when the people will take a seat,, cause injury of human, there is potential safety hazard if forget and depress the seat front end then can sit empty situation; (3), to be returned to folded state process medium velocity at seat fast, noise is big, influences the peace and quiet of surrounding enviroment, influences others.

Summary of the invention

The utility model purpose provides a kind of seat and can reverse upset fold, and folding back is attractive in appearance, safe in utilization, and answer speed is slow, the Collapsible seat that noise is little.

For achieving the above object, the utility model adopts following technical scheme:

A kind of Collapsible seat comprises seat 5, seat bracing frame 6, and torsion spring 13 also comprises:

Seat supports 1 is fixedlyed connected with seat bracing frame 6;

Seat coupling assembling 4 is fixedlyed connected with seat 5;

Upper shell 3, hinged with seat coupling assembling 4 by axle 7, hinged with seat supports 1 by axle 9;

Lower house 2, hinged with seat coupling assembling 4 by axle 8, hinged with seat supports 1 by axle 10;

Damper 11, fixing by the axle that is fixed on seat supports 1 and the upper shell 3.

Described seat bracing frame 6 is fixedlyed connected with ground; Described torsion spring 13 is a torsion spring, is fixed on the connecting axle 9, is with hush pipe 12 therebetween; Described seat coupling assembling 4, seat supports 1, upper shell 3, lower house 2 are the U type.

Compared with prior art, the utlity model has following characteristics: (1), as can be seen by technique scheme, seat supports 1, seat coupling assembling 4, upper shell 3 and lower house 2 are by quadric chain of axle 7,8,9,10 hinged formations, this quadric chain can realize that seat 5 reverse upsets are folding, promptly upwards folding from seat 5 rear ends, this method for folding makes the use face of seat 5, and promptly the front is exposed, non-use face is that the back side of seat 5 stashes, and feels attractive in appearance to the people; (2), the utility model adopts the middle rear end both sides application of force of seat 5 and realizes that seat 5 launches, like this, the people takes advantage of a situation and drives seat 5 when sitting down naturally and launch, even forget expansion seat 5, the people can not taken place yet sit empty accident, can not damage human body, and is safe and reliable.(3), the utility model adopted damper 11 and muffler 12, the answer speed that slowed down has reduced the noise that produces in replying.

Fig. 1 is the utility model most preferred embodiment schematic diagram, shown in solid line be reset mode, double dot dash line is a user mode.

Fig. 2 is a reset mode internal structure schematic diagram.

Fig. 3 is a user mode internal structure schematic diagram.

Among the figure: 1. seat supports; 2. lower house; 3. upper shell; 4. seat coupling assembling; 5. seat; 6. tables and chairs bracing frame; 7. connecting axle; 8. connecting axle; 9. connecting axle; 10. connecting axle; 11. damper; 12. hush pipe; 13. torsion spring.

The specific embodiment

Below in conjunction with accompanying drawing and most preferred embodiment the utility model structure and characteristics are described in detail.

Fig. 1 is the utility model schematic diagram, also is the most preferred embodiment schematic diagram.Clearly among the figure shown user mode of the present utility model and the folded state that resets, simultaneously also as can be seen seat 5 are reverse upsets, promptly the rear end of seat 5 upwards upset reach folding effect.

Among Fig. 1, seat bracing frame 6 is fixedlyed connected with ground, and seat supports 1 is fixedlyed connected with seat bracing frame 6, and seat coupling assembling 4 is fixedlyed connected with seat 5.Upper shell 3 is hinged by axle 7 with seat coupling assembling 4, and is hinged by axle 9 with seat supports 1; Lower house 2 is hinged by axle 8 with seat coupling assembling 4, and is hinged by axle 10 with seat supports 1.Like this, seat supports 1, seat coupling assembling 4, upper shell 3 and lower house 2 are by quadric chain of axle 7,8,9,10 hinged formations, and this quadric chain can realize that seat 5 reverse upsets are folding, i.e. the upwards upset from seat 5 rear ends reaches folding effect.As seen from Figure 1, this method for folding makes the use face of seat 5, and promptly the front is exposed, and non-use face is that the back side of seat 5 stashes, and feels attractive in appearance to the people.Launch owing to both sides, the middle rear end application of force that adopts seat 5 realizes seat 5, like this, the people can take advantage of a situation and sit down, and seat 5 is launched simultaneously, launches seat 5 even people forget, also can not sit empty accident, can not damage human body, and is safe and reliable.

Fig. 2 is the utility model reset mode internal structure schematic diagram; Fig. 3 is a user mode internal structure schematic diagram.From 2 figure, can more be expressly understood architectural feature of the present utility model, operation principle and characteristics.Torsion spring shown in the figure 13 is a torsion spring, is fixed on the connecting axle 9, is with hush pipe 12 therebetween; Damper 11, fixing by the axle that is fixed on seat supports 1 and the upper shell 3.

User mode in that seat 5 shown in Figure 3 launches plays position-limiting action when seat coupling assembling 4 contacts with upper shell 3, spring and damper all are in compressive state this moment.When the people stands up to off normal, rely on the automatic upset of the torsion realization seat 5 of torsion spring 13, be returned to folded state.And the use of damper 11 and hush pipe 12 makes seat 5 speed that slowed down in reseting procedure, reduced noise.

Technical solutions of the utility model are suitable for the design of any folding seat, are particularly suitable for the place that large-scale crowds such as classroom, library, meeting room concentrate.

With most preferred embodiment structure of the present utility model and function, characteristics are described in detail above; multiple adjustment, change and modification that the technical staff that this area is familiar with carries out on the basis of technical solutions of the utility model are all within the utility model protection domain.
