The utility model relates to a foldable chair for children attached to the cycle whose chair seat, chair pen and foot rack can be folded. When the foldable chair for children attached to the cycle is folded, the size is small, so the movement of two legs of a rider and the turning of handle-bars are not influenced without disassembly. When the foldable chair for children attached to the cycle is opened, the foldable chair for children attached to the cycle can become a child chair with a backrest and a foot plate. The utility model has the advantages of convenient operation, simple structure, easy production and wide material source.

Description

Foldable chair for children attached to the cycle

The utility model is a kind of its seat, and chair encloses and puts the equal Foldable bicycle child of sole seat.

That sells in the market is placed in the seat that bicycle shoulders greatly and all can not folds People's Republic of China's regulation of road traffic control regulation: " be not with the people by bike, the band preschool child can only be with 1 people, and will little seat be installed shouldering greatly." according to this regulation, use in the market little seat band child's bicyclist, can both realize: overslaugh the motion of two legs, influenced turning to of handlebar, overslaugh too when especially not being with the child is if just inconvenience more of minibike.Therefore a lot of band child persons pull down seat when not being with the child for comfortable, easily, ride freely, refill when being with the child again.Sometimes wanted repeated multiple times in one day, very bother, a bamboo chair was used for two March like this and will be damaged, and had brought certain loss for economy, time.

The purpose of this utility model provides a kind of seat, chair encloses and put the equal Foldable bicycle child of sole folding chair.This folding chair does not need demolition just can make turning to of bicyclist's two legs motion and handlebar free and relaxed when not being with the child.

Characteristics of the present utility model are: be installed in the seat that bicycle shoulders greatly and be placed in the foot rest of putting that bicycle tiltedly shoulders; The seat support panel be fixed on the chair of shouldering greatly and shoulder and decide folder and hand over axle to be connected; Axle is being connected articulated connecting rod between seat railing and the seat support panel, puts sole and decide the friendship of sole folder and spool is connected.

The utility model is made up of two inventions that belong to a total inventive concept, that is: be installed in the seat that bicycle shoulders greatly and be installed in the foot rest of putting of tiltedly shouldering.

Such as Fig. 4,9, the chair of the utility model chair body bottom is shouldered and is decided folder (4) and seat support panel (11) seat and hand over axle (1) to hand over axle to be connected, chair is shouldered and is decided that four holes are arranged on the folder (4), be positioned at two bolts hole that the hole is fastening bolt (2) on both sides, fastening bolt (2) inserts and chair shouldered behind this Kong Yuqi nut screwing clamping to decide folder (4) to be fastened on bicycle to shoulder greatly, two holes in the middle of being positioned at are panel support pin-and-hole (10), panel support pin (5) can support seat support panel (11) after inserting this hole, makes two seat support panels (11) constitute seat. Being positioned at chair shoulders " several " shape of deciding folder (4) and shoulders greatly clamp (3) and itself and chair are shouldered decide folder (4) by fastening bolt (2) and be fastened as a whole, its effect is to make seat smooth, shoulder greatly stretched head (25) that clamp (3) stretches out seat support panel (11) and be used for seat pad panel support pin (5) when folding, the paint that panel support pin (5) wearing and tearing are shouldered greatly when avoiding riding. Have and the rectangular narrow limit of the plate face of seat support panel (11) shouldering seat support panel (11) edge that decides beyond folder (4) the concurrent aces coupling part with chair, play a part to strengthen seat intensity. Equal respective shaft is connecting the lower end of three articulated connecting rods (7,19,20) on the narrow limit at two seat support panels (11) edge, and the equal respective shaft of two seat railings (8,26) is connecting the upper end of three articulated connecting rods (7,19,20). The rearward end axle of seat railing (26) is connecting an end of chair back backup plate (6), the seat in use intrinsic double step rivet of the other end of chair back backup plate (6) snaps in breach (22) on the seat railing (8), seat is when folding, the double step rivet snaps in the breach (23) on the seat railing (26), such seat railing (8,26), chair back backup plate (6) has just formed chair with two groups of identical articulated connecting rods (7,19,20) and has enclosed. Articulated connecting rods (7,19,20) has illicit relations with quiet 1 by the two joint book instep  hook mulberry  waterside guanidine witch  that axle intersected with each other connects) joint that links to each other intrinsic "

" shape hook (21), be used for seat hook seat railing (8,26) when folding, seat railing (8,26) is played position-limiting action, to the orientation that folded of articulated connecting rods (7,19,20). One end of positioning hanger (9) is connected 7 with the front end of seat railing (8,26) with articulated connecting rods) upper shaft be connected, the breach of the other end of positioning hanger (9) snap in the middle of the articulated connecting rods (19) shape for "

" the little shaft shoulder of two shoulder axles on (seeing Fig. 4,9) positioning hanger (9) and seat railing (8,26) and the stable triangle of articulated connecting rods (19) formation, make chair enclose setting.

Such as Fig. 5,6, the right side is considered as " U " shape, just is being considered as trapezoidal deciding sole folder (17) and put sole (14) and is handing over axle (16) to be connected as a single entity through plate holder. Deciding has four holes on the sole folder (17), and contiguous plate holder is handed over two Kong Weiding plate pin-and-holes (15) of axle (16), and other two holes are the jack of fastening bolt (13). " Jiong " shape lining frame (18) is positioned at decides sole folder (17), fastening bolt (13) insert in fastening bolt (13) jack decide on the sole folder (17) and with its nut screwing clamping, can make and decide sole folder (17) and serve as a contrast frame (18) to be fastened on bicycle and tiltedly to shoulder. Putting for two all has a breach (27) on the sole (14), when putting foot rest and not using, start and put sole (14), snaps in fastening screw (12) at its breach (27), puts foot rest and namely is in the folded state (see figure 6). Put foot rest in use, after the breach (27) of putting sole (14) takes off fastening screw (12), insert in the dowel hole (15) of deciding on the sole folder (17), can prop up and put sole (14) (see figure 10).

The utility model structure design compactness, volume after folding is very little, and is easy to use, produce easily, the raw MAT'L wide material sources, with low cost, extensive market.

Each parts operative relation of the utility model and use operating mode are provided by following embodiment.

The utility model is installed by position shown in Figure 11 in use.Chair shouldered decide folder (4) and be stuck in bicycle and shoulder greatly, shoulder clamp (3) greatly by (Fig. 9) insertion, the seat support panel (11) that is under the folded state is started, shoulder two holes of deciding folder (4) both sides and insert binding bolt (2) being positioned at chair then, tighten its nut, seat just is fixed on greatly and shoulders like this.Panel support pin (5) middle part is the garden arc, by garden nock face, direction to seat support panel (11), with panel support pin (5) insert chair shoulder in the panel support pin-and-hole of deciding on the folder (4) (10) to garden camber line intermediate point be positioned at shoulder the place greatly till, the seat support panel (11) that is placed on like this on the panel support pin (5) has just constituted the seat (see figure 9) with the end face of shouldering clamp (3) greatly, pull-up seat railing (8,26) trip shaft is connected the chair back backup plate (6) on the seat railing (26), make double step rivet on the chair back backup plate (6) leave breach (23) face on the seat railing (26) and snap in lack (22) on the seat railing (8), the breach that will link up with (9) one ends surely snaps on the little shaft shoulder of two shoulder axles of articulated connecting rod (19) middle part (sees Fig. 4,9) so just having constituted chair encloses.
