(5) specific embodiment

With reference to Fig. 1,2, the preferred embodiment with swing that auxiliary pin leans on of the present utility model comprises: a base unit 2, is the seat support unit 3 that swings, these base unit 2 front and back relatively, and an adjustment positioner 4 that is assembled on the seat support unit 3.

Base unit 2 can be organized tranverse connecting rod 22, two swing units 23 that down extended by tranverse connecting rod 22 respectively that stand on the ground and comprise two bracing frames of setting up at interval 21, a connection support frame as described above 21 tops, and an awning 24 that is assembled in tranverse connecting rod 22 top sides, each bracing frame 21 has the hack lever 211 of two diagonal brace states.The position, top of each hack lever 211 is to link mutually, and swing unit 23 has the swing connecting bar 231 of two ramp interface, the position, top of this described swing connecting bar 231 is that pivot is tied on tranverse connecting rod 22 simultaneously, makes swing unit 23 be center swing freely by tranverse connecting rod 22.

Cooperation is with reference to Fig. 3, but seat support unit 3 be swing be assembled in swing unit 23 1 lower ends, seat support unit 3 has two left sides, the right first in command 31 who is provided with separately in pairs, two second in command 37 that are arranged at the described first in command 31 left sides in pairs, one be located at 37 of the paired first in command 31 and the second in command put seat 38, two laterally are linked to the described first in command 31 and the described second in command's 37 the front side and the bottom bar 30 of rear side respectively, two back of the body frames 32 of being located at 37 of the described first in command 31 and the described second in command respectively, four upper push-rods 33 that are hubbed at the dual-side of described back of the body frame 32 respectively and extend forward, four lower push-rods 34 of being located at described back of the body frame 32 bottoms respectively and extending equally forward, and two pin that are connected to paired described upper push-rod 33 and described lower push-rod 34 front ends respectively are by frame 35.Put seat 38 and be loaded on the plate body of 31,37 top sides on adjacent first and second handle, and can be used to put article on the surface for the while frame.Base unit 3 also has the cushion 362 and that a back cushion 361, that is fixedly arranged on back of the body frame 32 front sides is located at upper push-rod 33 top sides and is installed in the pin back cushion 363 of pin by frame 35 front sides.

And in the above-described structure, seat support unit 3 has two groups of left-right symmetry and constructs identical space kenel, the therefore following only just first in command's 31 explanations.

Shown in Fig. 2,3, the described first in command 31 is inverted U-shaped outward appearance and has the rail segment 312 that one in front and one in back parallel straight bar section 311, is engaged on described straight bar section 311 tops, and an almost parallel status is in the bottom bar section 313 of straight bar section 311 bottom sides.

Each upper push-rod 33 is to be assembled along line shifting ground and each first in command 31, and its forward and backward two opposite end then is that the pivot knot leans on frame 35 and back of the body frame 32 at pin respectively, 34 of described lower push-rods are to be located at each upper push-rod 33 below respectively almost parallel, and its forward and backward two opposite end also is that pivot is tied in pin by frame 35 and back of the body frame 32 respectively, whereby, make back of the body frame 32 is to be combined in 31 of two first in command preceding pivot pendulum, and back of the body frame 32 also can be via first and second push rod 33,34 synchronous interlock pin by frame 35.

Shown in Fig. 2,3,4, adjusting positioner 4 promptly is in order to fix the angle after back of the body frame 32 and pin lean on frame 35 pivots pendulum, adjust positioner 4 and have two guide members 41, two that are located at the first in command's 31 front ends respectively and be incorporated into described upper push-rod 33 sides and sliding part 42 that can straight line moves on guide member 41 respectively, and one removably combines the fixture 43 that also can compel to guide member 41 with sliding part 42.

Guide member 41 has the upper and lower rail bar 411 that be arranged in parallel with the angle of inclination, and 411 on said rail bar defines the linear ramp 412 of one or two end sealing, and sliding part 42 promptly is that the while spiral-lock is on described two rail bars 411, and utilizing one, to pass the screw rod 44 of linear ramp 412 affixed with upper push-rod 33, sliding part 42 can be moved along the bearing of trend of linear ramp 412 and near above the expansion position with near below receipts lean between the position and shift.Fixture 43 promptly is to penetrate the top of sliding part 42 and support with rail bar 411 near the top to compel, this fixture 43 has the threaded rod 431 that a surface has a plurality of screw threads and can support rail bar 411, and one be located at the swivel head 432 of this threaded rod 431 away from the rod end of sliding part 42, rotates swivel head 432 whereby and drive threaded rod 431 and move back between state and shift compeling the state that supports and pine.

Shown in Fig. 4,5, when the relative guide member of fixture 43 41 moves back state for pine, the back of the body frame 32 of seat support unit 3 just can be swung by frame 35 with pin and adjust the position, make back of the body frame 32 utilize rider's body weight to press by receiving by position (seeing Fig. 4) backward, interlock by first and second push rod 33, the 34 root support power that makes pin lean on frame 35 up to rise occupant foot is provided simultaneously, and this moment, sliding part 42 promptly can up move to expanded position along linear ramp 412.Anti-, when use utilizes the strength of foot that pin is depressed by frame 35 application of forces backward (seeing Fig. 5), also can drive back of the body frame 32 synchronously by first and second push rod 33,34, it is up risen once again and be resisted against occupant's back, sliding part 42 promptly can be returned back to above-mentioned receipts by the downward slippage of expanded position by the position.And this sliding part 42 move along linear ramp 412 bearing of trends during in, all can utilize fixture 43 to fix, to reach the effect of stepless adjustment.

And when fixture 43 relative guide members 41 were fixed state, the back of the body frame 32 of seat support unit 3 and pin promptly can't the pivot pendulum by frame 35 and adjust angle.

It should be noted that especially, seat support of the present utility model unit 3 is not that limitation has two groups of pin by the structure of frame 35 with back of the body frame 32, quantitatively also can be single pin by the kenel of frame 35 with 32 collocation of back of the body frame, perhaps also can be two groups of above pin by the collocation of frame 35 with back of the body frame 32, for example: three groups side by side.

Conclude above-mentioned, swing of the present utility model is to be provided with pin by frame 35 and back of the body frame 32 31 of the described first in command, and utilize described first, second push rod 33,34 make described both be able to interlock, the design of this kind structure can provide the root support power of user foot really and increase the comfort level of using, and the angle the when user also can adjust seating, so can reach the purpose of this utility model really.
