Description

Two-sided turning bridge row chair

The utility model relates to a kind of two-sided turning bridge row chair.

Existing bridge row chair is because of its design meets the ergonomics structure, uses more comfortablely, but can not overturn, so can only the single face use.Though and existing turnover panel chair can two-sided use, but use comfortable inadequately, and because its design generally is that rear foot top is articulated on the seat side, the forward foot in a step is articulated on the rear foot, has the linear guide chute in forward foot in a step inboard, and a slide-bar is housed on the seat side, the slide-bar termination is stretched in the chute, its bearing capacity is restricted, and practice also shows the phenomenon that the chair plate of this turnover panel chair in use also comes off often.

The purpose of this utility model is to overcome the deficiencies in the prior art, and in conjunction with the advantage that has turnover panel chair and bridge row chair now, designs a kind of two-sided turning bridge row chair.

The utility model is such realization:

A kind of two-sided turning bridge row chair relates to the chair forward foot in a step, the chair rear foot, seat, it is characterized in that position symmetrical on the seat two sides is fixed with a connection piece respectively, and connector is provided with guide rail, and the guide rail two ends are linear, and the centre is semicircle, and:

The chair forward foot in a step is articulated on the seat side by pin, and the centre of gyration of seat overlaps with the center of circle of the semi-circular portion of guide rail;

The top of the chair rear foot is articulated in the chair forward foot in a step by another pin;

In the chair forward foot in a step, the position of the pin of hinged chair rear foot Xiang Duan is positioned on the position of pin of hinged seat;

A sliding axle also is equipped with in appropriate position, chair rear foot top, and the end of sliding axle is stretched in the guide rail.

The pin that further scheme is the hinged chair forward foot in a step and seat also is positioned at center, seat side.

Further scheme is that the one side of seat is a hardfaced plate, and another side is the softpanel that is equipped with the flexibly thermal insulation material layer.

The Lower Half that further again scheme is the chair forward foot in a step is a linear, and the first half is a shaped form.

Characteristics of the present utility model are: combine the advantage of existing bridge row's chair and turnover panel chair, and durable, and:

1, be stiff dough because its seat can be designed to one side, one side is for to be covered with soft of adiabator layer, so can realize cold and hot two-sided use according to user's needs;

2, because its forward foot in a step top is the shaped form of the engineering structure when meeting human body by seat, the hand wing reliably is placed on chair forward foot in a step top, thereby makes the user that comfort be arranged.

Below in conjunction with accompanying drawing the utility model is described further.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, a kind of two-sided turning bridge row chair, relating to the bottom is that linear, top are the curved chair forward foot in a step 1 that meets the ergonomics structure, on the chair forward foot in a step 1 top backrest 12 is housed also; The U-shaped chair rear foot 2; One side is a hardfaced plate 10, and another side is the seat 3 that is covered with the softpanel 11 of flexible heat-insulating layer.Be fixed with connector 4 with rivet 9 respectively on the two sides of seat 3, drawn chute guide rail 5 on the connector 4, its middle guide 5 two ends are linear, and the centre is semicircle.And:

The chair forward foot in a step 1 is articulated on seat 3 sides by pin 8, and the centre of gyration of seat 3 overlaps with the center of circle of the semi-circular portion of guide rail 5.

Rear side in appropriate position, the chair forward foot in a step 1 top also has a sulculus, and the chair rear foot 2 tops embed in this groove and use pin 6 that the chair forward foot in a step 1 and the chair rear foot 2 is hinged.

In appropriate position, chair rear foot top one sliding axle 7 is housed also, the termination of this sliding axle 7 is stretched in the guide rail 5, and can slide along the track of guide rail 5.

When collecting at ordinary times, seat 3 front ends up can be promoted, sliding axle 7 just can move forward along the track of guide rail 5, and drive the chair rear foot 2 progressively near the chair forward foot in a step 1, be positioned at the cambered surface top of guide rail 5 track semi-circular portion until sliding axle 7, this moment, the chair forward foot in a step 1 overlapped substantially with the chair rear foot 2, and seat 3 also goes to uprightly.

When need use, seat 3 is promoted forward or backward, guide rail 5 will force sliding axle 7 to drive the chair rear foot 2 forks, and an end that is positioned at the straight line portion of guide rail 5 until sliding axle 7 can use.When need use the another side of seat 3, seat 3 front ends are upwards promoted, this moment sliding axle 7 just along the orbiting motion of guide rail 5, move to another rectilinear end until axle 7 from the rectilinear end of guide rail 5, this moment, seat 3 also was turned to another side from one side simultaneously.
