Description
Technical field
The utility model relates to a kind of tandem bicycle, particularly a kind of tandem bicycle that utilizes lever pushing.
Background technology
Along with China enters into aged society, increasing the retired lives in city and rural area, if and still competent the elderly wants to take exercise in trip closely or in the park leisure, then bicycle is good vehicle, but because the elderly is handicapped, trick is no longer flexible, so common bicycle is easy to fall down when riding, causes the senile fracture.Therefore if can invent a kind of bicycle of double four-wheel then can increase stability when travelling on the one hand, can allow simultaneously the elderly couple of retirement back after the leisure go on a journey in pairs again, talk while particularly on the path in woodland of some large-scale public places of entertainment, take exercise.The tandem bicycle that is provided with before and after some has been arranged at present, two-wheel before and after but it remains, the non-constant of stability, and used bicycle saddle cushion is because contact surface is little, very uncomfortable above riding over for a long time, therefore poor stability can't be walked abreast, and demands inventing that a kind of later-model energy is comfortable is seated and the tandem bicycle of safety traffic urgently.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of tandem bicycle in the prior art, and a kind of energy tandem bicycle that utilizes lever pushing that two people are seated shoulder to shoulder is provided.The utility model design utilizes the tandem bicycle of lever pushing, the vehicle frame of two similar bicycles about comprising, front and back wheel separately, it is characterized in that: about a seat is respectively arranged on the seat cushion bar of vehicle frame of two similar bicycles, about have between two vehicle frames at least two to be fixedly linked with cross tube, be provided with the pivot pin of a horizontal positioned in the following front portion of each vehicle frame, two pedal levers about being connected with on the pivot pin, there is stretcher on the last top of pedal lever, the middle part of each pedal lever connects the chain of one section pitch of the laps on a single direction ratchet of the middle and lower part of vehicle frame by steel wire, the other end of chain is connected with one section extension spring, extension spring is fixed on the bicycle rack, single direction ratchet connects chain wheel by internal tooth, there is loop chain to connect on the single direction ratchet that moves ahead of trailing wheel on the chain wheel, about in the handlebar on two vehicle frames one be fixing handlebar, another is the moveable cart handle, moveable cart is the front fork rotating shaft by the front-wheel on another vehicle frame of connecting rod captive joint, moveable cart on have before and after brake crank, the front and back brake crank is with adaptor union respectively on the brake by the front and back wheel of wire joint to two vehicle frame that is flexible coupling.The utility model has the advantages that to make things convenient for the elderly's driving that is seated when particularly old couple people lies fallow, because seat is on chair, it is more comfortable that the people feels, two car four-wheels can guarantee balance whenever, and are safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
The vehicle frame 1 of two similar bicycles about comprising among the figure, front and back wheel 19 separately, it is characterized in that: about a seat 2 is respectively arranged on the seat cushion bar of vehicle frame 1 of two similar bicycles, about have between two vehicle frames 1 at least two to be fixedly linked with cross tube 3, be provided with the pivot pin 4 of a horizontal positioned in the following front portion of each vehicle frame 1, two pedal levers 5 about being connected with on the pivot pin 4, there is stretcher 6 on the last top of pedal lever 5, the middle part of each pedal lever 5 connects the chain 9 of one section pitch of the laps on a single direction ratchet 8 of the middle and lower part of vehicle frame 1 by steel wire 7, the other end of chain 9 is connected with one section extension spring 10, extension spring 10 is fixed on the vehicle frame 1, single direction ratchet 8 connects chain wheel 11 by internal tooth, there is loop chain 12 to connect on the single direction ratchet 13 that moves ahead of trailing wheel 19 on the chain wheel 11, about in the handlebar on two vehicle frames 1 one be fixing handlebar 14, another is that moveable cart is 15, moveable cart is the 15 front fork rotating shafts 17 by the front-wheel 19 on another vehicle frame 1 of connecting rod 16 captive joints, moveable cart is brake crank 18 before and after having on 15, and brake crank 18 usefulness adaptor unions 20 in front and back are respectively by on the brake of the front and back wheel 19 of wire joint to two vehicle frame 1 that is flexible coupling (among the figure picture).
During double driving, two people are sitting on the seat 2, the stretcher 6 on top on the lever 5 is stepped in each personal pedal step of two people, along with the rotation around pivot pin 4 of pedal lever 5 can be rotated by the single direction ratchet 8 of steel wire 7 pulling vehicle frame 1 middle and lower parts separately, single direction ratchet 8 drives chain wheel 11 thereupon and rotates, chain wheel 11 is rotated by the single direction ratchet 13 that moves ahead of loop chain 12 pulling trailing wheels again, and the back-wheel drive bicycle moves ahead, and pedal lever 5 draws reposition by extension spring 10 again.And direction can be rotated the front fork rotating shaft 17 of the front-wheel 19 on another vehicle frame 1 of 15 synchro control by the moveable cart on bicycle wherein, guarantee two vehicle frame 1 equidirectional turning to, and brake also is by the moveable cart on this vehicle frame 1 the front and back brake crank on 15 18 to be controlled, and front and back brake crank 18 is connected on the brake of front and back wheel 19 of two vehicle frames 1 by adaptor union 20 one drag twos respectively.Finish the synchronous deceleration of 2 vehicle frames 1.
Move backward in order to finish to be sitting on the car, a reverse clutch control stalk 21 can be installed on left vehicle frame 1, be connected respectively on the power-transfer clutch (not drawing among the figure) that links to each other with single direction ratchet 8 by flexible cord, connect chain wheel 11 again, just can carry out the selection of forward-reverse thus, conveniently travel outside.
