Abstract
The utility model relates to a chair type bicycle which is a labor-saved, safe and comfortable vehicle for people to ride. The chair type bicycle is characterized in that a prepositive foot pedal lever-type driving device is adopted. The device is provided a left and a right foot pedal levers (3, 4) which are arranged on the front support frame of the bicycle. The foot pedal levers (3, 4) are connected with a link chain (5). The link chain (5) is engaged with back fly wheels (11, 12) by guide pulleys (6, 7). The link chain (5) can drive the back wheels to roll forwards when the foot pedal levers (3, 4) are pedaled so that the goal of continuously advance can be achieved. A chair seat (9) can be dropped so that air resistance can be reduced, and the purposes of saving labor, safety and comfort can be realized.
Description
The utility model is a kind of chair type bicycle.
Now the daily ordinary bicycle of riding of people is the front and rear wheel equal diameters, and driving power steps lever on the driving wheel single direction ratchet that drives on the trailing wheel that moves in a circle by both feet and rotates.Vehicle seat is subtriangular, simultaneously because vehicle seat gets up also uncomfortable than Theravada's seat.
In order to solve the shortcoming of present bicycle,, all do not break away from the basic model of present ordinary bicycle though people have found out various ways.
The purpose of this utility model is to provide a kind of chair type bicycle, and it has not only changed the basic model of present ordinary bicycle, and takes advantage of seat more comfortable, ride laborsaving, steady, safety.
The utility model is achieved in that 1, adopts preposition pedal type transmission device.A left side is equipped with in this mechanism on the bicycle front frame, right two pedal levers (3,4), corresponding two ratchets (flywheel) (11 that are equipped with on rear axle, 12), in vehicle frame bottom and upper frame rail front portion two pulleys (15) and two track adjusting wheels (6 are installed respectively, 7), chain (5) middle part is connected by cable wire (14), and turn to by pulley (15) and to be divided into a left side, right chain (5), through a left side, right ratchet (11,12) and track adjusting wheel (6,7) with a left side, right threading lever (3,4) be connected the transmission device that the transmission device that the traditional both feet of formation change move in a circle moves reciprocatingly for both feet.2, adopt the chair type vehicle seat.3, adopt the big steamboat configuration that front-wheel is little, trailing wheel is big.4, adopt the speed-changing mechanism of variable force arm type.
Because the utility model has changed the basic model of present ordinary bicycle, change is ridden by double-legged circus movement and is ridden into back and forth seesawing by pedal, so it is laborsaving to ride.Because vehicle seats has reduced the height of riding, so the personnel's that ride barycenter reduces, reduce air resistance, be difficult for toppling over, it is safer to ride.Also, therefore can adapt to different roads and ride because the utility model has adopted simple speed-changing mechanism.
The contrast accompanying drawing is described in detail the utility model below.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the sketch of the utility model transmission device.
Describe concrete structure of the present utility model and service condition in detail below in conjunction with Fig. 1.
(1), structure
Structure of the present utility model is made up of vehicle frame, motion parts, running part, variable part, seat part, brake portion, turning part branch.
1, vehicle frame: vehicle frame (16) is the main body that connects each several part, constitutes the basic framework of bicycle.
2, motion parts: comprise preceding wheel assembly (18) and rear wheel assembly (13), preceding wheel assembly is connected front fork (17) by front axle, and rear wheel assembly (13) is connected on the vehicle frame (16) by rear axle.Because the big steamboat configuration of having taked that front-wheel is little, trailing wheel is big, satisfying the requirement of turning of bicycle, and the corresponding height that reduces seat, height of seat is lower 450 millimeters than ordinary bicycle vehicle seat.Owing to highly reduce, reduced the air resistance (according to the data introduction, air resistance accounts for consumption of power about 50%) when riding.Thereby make when riding more laborsaving.Barycenter is low, it is more steady to be difficult for toppling over, to ride.
3, running part: running part is made up of left and right sides pedal lever (3,4), chain (5), cable wire (14), guide wheel (6,7), pulley (15).
Chain (5) middle part connects lodge on pulley (15) by cable wire (14), turns to by pulley (15), is divided into left and right sides chain.Left and right sides chain is meshed with left and right sides flywheel (11,12), is connected with left and right sides pedal lever (3,4) through guide wheel (6,7), forms closed left and right sides interlock transmission device.
4, variable part: left and right sides transmission system (1,2) is installed on the pedal lever of the left and right sides.This transmission system mainly is the connection location that changes chain and pedal lever, reaches the length that changes the arm of force and speed change, when the chain point of connection is mobile below pedal lever (3,4), the arm of force is short, firmly big, the chain mobile range is big when scrunching, and the speed of a motor vehicle is just fast, adapts to region of no relief and rides.When the chain point of connection was mobile above pedal lever (3,4), the arm of force was long, and the chain mobile range is little, and moment is big, adapts to the needs of riding in the mountain region.
5, seat part: the framework of seat (9) is a plastic part, and is comfortable in order to ride, and lays the sponge cushion rubber above.A cargo compartment (10) is installed in the back of back of seat, and seat is fixed on upper frame rail, can move forward and backward, to adapt to the needs that the differing heights personnel ride.Owing to adopt the chair type vehicle seat, not only make the personnel of riding comfortable, indefatigability is convenient to firmly in addition.According to the human engineering principle, the people is seated, and to become the state of partly lying firmly optimum, also maximum.According to the data introduction, get and sit 262 kilograms of gesture right pedal Li Keda, left foot can reach 241 kilograms.If ride ordinary bicycle, it is body wt that maximum is pedaled power.
6, brake portion: brake portion adopts common jaw type cable brake.Structure is identical with ordinary bicycle with installation.
7, knuckle section: the knuckle section structure is identical with installation and ordinary bicycle.
(2), service condition
Here mainly introduce the service condition of cycle racing process.
When stepping on a left side or right threading lever (3,4) with pedal, drive chain (5) and move forward.Chain (5) drives flywheel (11,12) and rotates, and because of flywheel is a single direction ratchet, can not produce relative rotation with hind axle, and the power that trailing wheel (13) rolls and provides bicycle to advance forward is provided flywheel (11,12).Meanwhile a left side or right chain (5) move after driving by cable wire (14), make angular transposition of the corresponding generation of a left side or right threading lever (3,4).Constitute a suitable position of pedaling forward.Left and right sides pin hockets like this, left and right sides chain (5) and left and right sides flywheel 11,12) driving and driven mutual conversion, action is carried out repeatedly, the purpose that bicycle is reached advance continuously.
Claims (2)
1, a kind of chair type bicycle, it is characterized in that on the bicycle front frame left side being housed, right two pedal levers (3,4), corresponding two ratchets (flywheel) (11 that are equipped with on rear axle, 12), in vehicle frame bottom and upper frame rail front portion two pulleys (15) and two track adjusting wheels (6 are installed respectively, 7), chain (5) middle part is connected by cable wire (14), and turn to by pulley (15) and to be divided into a left side, right chain (5), through a left side, right ratchet (11,12) and track adjusting wheel (6,7) with a left side, right threading lever (3,4) be connected, constitute preposition stretcher lever transmission device.
2, bicycle according to claim 1 is characterized in that adopting that front-wheel is little, trailing wheel is big large and smallly takes turns configuration.
