The invention relates to vehicles driven by human muscle force.Famous pedal-and-rod asterisk /application, Republic of Belarus N 20000670, 10.07.2000,/, containing bar, on which are fixed on both sides from its center of rotation of the drive sprocket made them drive teeth, and strip made extra holes for mounting the drive sprocket.It is also known vehicle p is e on it the steering wheel from the steering fork, the front and rear wheels, saddle, crank mechanism with the crank sprocket, through which the chain is connected to the driving sprocket.A disadvantage of the described device is that it is impossible without disassembling the pedal-crank sprocket or its replacement to change the speed of the device.The present invention is the task of creating a vehicle driven by human muscle force, which is due to changes in design would be adapted for riding in mountainous terrain and on the road.This task is solved in that in the vehicle driven by human muscle force, containing a frame mounted on it the steering wheel from the steering fork, front and rear wheels, a saddle, a pair of pedals with rods mounted on the axle with the pedal-crank sprocket, consisting of planks, on which are fixed on both sides from its center of rotation of the drive sprocket made them drive teeth, and a pedal-crank sprocket through a chain connected with the driven sprocket, according to the invention the strap is equipped with slides, on which is mounted drive sprocket, and each slider has, at least, DV is entrusted to the longitudinal axis of rods at different angles.The execution of a pedal-crank sprocket with slides, on which is mounted drive sprocket to lock the slide by means of pins allowed to switch the device quickly without breaking it, which is important when driving in mountainous terrain and on the road. The possibility of displacement of the longitudinal axis of the strap relative to the longitudinal axis of the connecting rod to the desired angle has improved pickup device.Ultimately expanded operational capabilities of the vehicle.The invention is further explained in the description of example with reference to the accompanying drawing, which shows a vehicle according to the invention, side view.The vehicle, driven by human muscle force, according to the invention includes a frame 1 mounted on it, the steering wheel 2 to the steering fork, front and rear wheels 3, a seat 4, a couple of pedals with rods 5, mounted on the axis of the connecting rod 6 together with the pedal-crank sprocket, consisting of a strap 7, which has 8 sliders attached to them drive sprocket 9, and the sliders 8 are fixed by means of pins 10 and holes 11, performed on a strap 7, and p is redstem pin 14 and holes 15, made on a strap 7, with the pedal-crank sprocket connected by a chain 16 is driven sprocket 17.The proposed vehicle is used as follows:
The driver sitting on the seat 4, presses the pedal 5, which causes the connecting rods, and along with them through the axis 6 of rods and pedal sprocket, which has the ability to change the speed by means of pins 10 and holes 11, performed on a strap 7, thereby to increase the distance from the center of the crank sprocket to the teeth of the drive sprocket 9, or respectively decrease, thereby changing the speed. Next, the pedal-crank sprocket leads through the chain 16 during the rotation of the driven sprocket 17, thus reducing or increasing the angle of the longitudinal axis 12 of the strap 7 with the longitudinal axis 13 of rods 5 by means of the switching pin 14 mounted on the rod 5 on the other hole 15 made in the strip 7, allows you to change the output device.It should be understood that the above-described exemplary embodiment of the vehicle are given in a purely illustrative purposes and does not limit the invention, which can be made various changes or modifications not beyond its size, which is about Patsy drive sprocket, can be accomplished through a pendulum rocking or ellipses washers for it places the detent sliders, and changing the angle of the longitudinal axis of the strap and connecting rods can be fixed by means of two washers, mounted independently on a strap and the rod performed on their teeth, and they are fixed by dogs.The proposed vehicle can be used in transportation, household, medical and sports equipment. 1. The vehicle, driven by human muscle force, containing a frame mounted on it the steering wheel from the steering fork, front and rear wheels, a chain, a pair of pedals with rods mounted on the axis of rods pedal-crank sprocket, consisting of planks, on which are fixed on both sides from its center of rotation of the drive sprocket made them drive teeth, and a pedal-crank sprocket is connected with the driven sprocket, wherein the strap is equipped with slides, on which is mounted drive sprocket, and each slide has at least two fixation points.2.
