Balance bike frame

 

(57) Abstract:

Use of invention: in the rental. The inventive balance bike frame center of gravity (along with cyclist) is located above a large rear wheel. Pipe steering column lower end pivotally attached to the frame. The upper end of the tube is placed between welded to the frame sidepieces with the slots, a couple of which are inserted located on the pipe the heck. Lifted the latch by means of a rope, and is inserted into another pair of grooves forces of gravity and the springs. To the upper end of the tube is attached a spring, the other end fixed to the frame. Behind the rear wheels are elevated above the ground safety wheel, frame bending and straightening of the back is able to balance the center of gravity on uneven terrain and install the appropriate location step bike. Balancing the center of gravity at different size wheels will allow you to effectively use the force of gravity when riding downhill and reduce its negative impact on the rise. 1 Il.

The invention relates to the rental.

Famous bike that contains a frame, front and rear wheels, one small, the other large is Germany N 39325, CL C,2, 1889).

The task of the invention is the balancing of the centre of gravity for different size wheels will allow you to effectively use the force of gravity when riding downhill and reduce its negative impact on the rise.

The drawing shows a balance bike frame.

Balancing two-wheeled Bicycle frame, the front wheel is small, and the rear is large, the center of gravity of the frame together with the cyclist is located over the rear wheel. The steering column tube 1 lower end pivotally attached to the frame 2. The upper end of the tube is placed between two welded to the frame sidepieces 3 with grooves 4, a couple of which are inserted located on the pipe latch 5. From the top to the latch attached to the cable 6, the other end of which is attached to the grip on the handlebars. From the bottom to the latch attached to the spring 7, the other end of which is fastened to the pipe. To the upper end of the pipe attached to the spring 8, the other end fixed to the frame. In a static condition and when riding on flat terrain heck captures the average step of the bike, and spring polarstate. Behind the rear wheels are elevated above the ground auxiliary wheel 9.

On lifting the rider presses down on the handle, lifting the latch 5, and necrodius up and back. The nose of the frame is lowered and the seat moves forward, balancing the center of gravity. The cyclist releases the handle and the latch 5 forces pressing and springs into the next pair of grooves of the arms 3, locking shortened step bike. The rise of the latch when riding downhill is accompanied by hyperextension of the back.

The ability of the spring to respond to changing load on the front wheel will provide a balanced center of gravity and establishing appropriate location step of the bike.

The efficiency of the force of gravity on the nerve area depends on the size of the wheel. So lifting it with a larger burden on small wheel, and come down harder on the big wheel.

Balance bike frame containing a frame, front and rear wheels, one small, the other large, safety wheel, forks, wheel, steering column tube, the lower end mounted on the frame, wherein the front wheel is small, and the rear is large, the center of gravity of the frame together with the cyclist is located over the rear wheel, security wheel is elevated above the ground behind the rear wheels, the lower end of the tube of a steering column mounted on the frame hinge, the part of the pipe with the opportunity to interact with the slots of the arms, a cable attached at one end to the top latch and the other to the handle on the steering wheel and springs, one of which is attached to one end of the bottom to the latch, and the other to the pipe, and the other attached at one end to the upper end of the pipe, and the other to the frame.
