Veloped

 

(57) Abstract:

The invention relates to velotron, designs sports, travel, tourism and cargo bikes. Veloped contains pedals, pedal levers, each of which is fitted with a latch and mounted to rotate on an axis while moving it up and down. Has ratchet wheels, each of which is mounted on the shaft firmly for communication with the corresponding pedal lever. Ratchet is also connected through the gear, the intermediate shaft and the transmission sprocket wheel. Veloped has also springs. Each spring is connected with the corresponding pedal arm and has the ability to stretch with the movement of the pedal lever down to the bottom dead point. The transmission on one of hrapovic wheels is carried out by entering dogs in the ratchet wheel when the spring compression. When this transmission has a drive sprocket mounted on the intermediate shaft disposed between the axle and driven sprocket connected by a chain with a leading asterisk. The objective of the invention is the improvement of operational properties for easy pedaling and increase speed. 2 Il.

The invention relates to holoscreen, the local veloped, containing pedals, pedal levers, each of which is fitted with a latch ratchet and mounted to rotate on an axis while moving them up and down, star wheels, each of which is mounted on a shaft rigidly for communication with the corresponding pedal lever, and on the other hand the star wheels are connected through the gear, the intermediate shaft and the transmission sprocket wheel, and spring (FR N 539957, CL 63 K 2, 1922).

A disadvantage of the known designs is the lack of speed due to the labor intensity pedaling.

The aim of the present invention is to remedy these disadvantages, the improvement of operational properties for easy pedaling and increase speed.

This goal is achieved by the fact that the proposed veloped contains pedals, pedal levers, each of which is fitted with a latch, a ratchet wheel mounted to rotate on an axis while moving them up and down. Each of hrapovic wheel is mounted on a shaft rigidly for communication with the corresponding pedal lever, and on the other hand ratchet wheel connected through the gear, the intermediate shaft and the transmission sprocket wheel. Each of the two springs associated with sootvetstvii point and is transmitted to one of hrapovic wheels by entering dogs in the ratchet wheel under compression. When this transmission has a drive sprocket mounted on the intermediate shaft disposed between the axle and driven by the rear sprocket wheel connected by a chain with a leading asterisk.

In Fig. 1 shows a General view of a Bicycle with the installed valoprovoda; spring stretched halfway. In Fig. 2 is a view of veloped top.

Veloped includes left pedal lever 1, the right-hand pedal lever 2, axis 3, ratchet wheels 4 and 5, gear 6, and 7, the intermediate shaft 8, the drive sprocket 9, the pedal 10 and 11, a frame 12, a spring 13 and 14, the pawls 15 and 16, the bracket 17, the sprocket of the rear wheel 18, the finger grip 19, 20 and 21 of the spring, the pedal bracket 22 and 23.

Veloped works as follows.

Cyclist feet foot pushes the pedal 10, the lever 1, freely pivots 3, will go down to the lowest point and thus the spring 13 will be stretched to the limit of the movement trajectory down, after which the pedal stops. Spring will return to the upper initial position, the pawl 15 will grasp the tooth ratchet wheel 5. Ratcheting 5 wheel rigidly mounted on the axle 3, so the spring force is transmitted to the gear 6, and then through the gear 7 is it in motion. The bracket 17 is attached to the chassis 12. The device shaft 8 is the same as the standard axis 3.

The cyclist presses the other foot on the pedal 11 and the pedal goes to the lower position together with the lever 2, freely perforated on the axis 3. The spring 14 will be stretched and the cyclist stops pressing on the pedal. Spring will begin to return to the upper initial position, the pawl 16 will grasp the tooth of the ratchet 4, which is rigidly mounted on the axle 3, the force is transmitted to the gear 6, and then to the gear 7, the shaft 8, the drive sprocket 9 and through the chain on the sprocket 18 of the rear wheels and thus the drive wheel receives power two times more than usual. This is because the springs 13 and 14 both strained, therefore, both independently of each other creates a force twice as large than in the known valoprovoda during their work.

First in the upper position come the pedal 10 and the cyclist again by pressing the legs will drop it in the lower position, etc.

It should be noted that the springs 13 and 14 should not be too tight, since the time of loading of the spring (one), i.e. the translation of it to the bottom position should occur quickly, so that the efforts of the two springs 13 and 14 were summed up in valoprovoda.

and to begin to help the spring one, or both, i.e., a leg or both legs, you can start to raise up, clutching thus the foot over the pedal bracket 22, 23.

The proposed veloped well suited for velomobiles, where you can simultaneously use two or more people.

The proposed design valoprovoda can be used on a road bike "Ural", especially because the construction is simple and the manufacture of parts is not difficult.

Veloped containing pedals, pedal levers, each of which is fitted with a latch and installed with the angle C when moving it up and down, ratchet wheels, each of which is mounted on the shaft firmly for communication with the corresponding pedal lever, and on the other hand ratchet wheel connected through the gear, the intermediate shaft and the transmission sprocket wheel, and springs, wherein each spring is connected with the corresponding pedal arm and has the ability to stretch with the movement of the pedal lever down to the bottom dead point and is transmitted to one of hrapovic wheels by entering dogs in the ratchet wheel in compression, while the transmission has a drive sprocket mounted on the intermediate shaft, R is
