Embodiment Construction

[0117] In more detail, the above-mentioned views show one of the possible features of the invention, wherein the inventive device is equipped with a braking mechanism (30) which prevents the movement of the crank (3).

[0118] In fact, when the cable (31) of the mechanism releases the helical spring (35), the wedge (32) descends, latching onto the tooth of one of the sprockets (24) of the crankshaft, thus avoiding said crankshaft (20), and therefore the crank (3) moves;

[0119] Conversely, when the cable (31) compresses the spring (35), the spring contracts and moves upwards carrying the wedge (32) connected to it, said connection being possible through the wedge top (33) as shown.

[0120] The cable (31) that activates the braking mechanism must be triggered through a handle located in the handlebar.

[0121] Whenever said brake mechanism (30) is not activated, when the rider moves the cranks (3) by applying force to the pedals (2) or handles, the crankcase (4) of each cran...

Abstract

The present invention relates to a device (1) for bicycles or other vehicles driven by pedals or handles, provided with at least one crankshaft (3) with a pedal (2) at one end and a gearbox (4) at the other end, the gearbox (4) having a groove and being located next to a fixed structure provided with a pin, the device being characterised in that the movement of the crankshaft is limited by the path of the pin in said groove, in that the gearbox (4) houses a torsion spring, in that the device is also provided with a mechanism for locking the toothed wheels on the rotation shaft of the crankshaft (24), in that these wheels (24) mesh with the toothed wheels in the gearbox, this gearbox being connected to the casing (63) of the axle having a toothed body, and in that the toothed wheels of the gearbox in turn transmit the movement to the outer axle.

Description

technical field [0001] The present invention relates to a device that is equipped in newly assembled bicycles or other pedal-powered vehicles and that can be retrofitted to existing vehicles so that these vehicles can be operated by operating one or two pedals or Movement with one or two handles without requiring much force, balance and / or strength from the user. [0002] In contrast, bicycles are equipped with mechanisms that are easy to activate and require no special skill. [0003] The device can be used by anyone, especially for people with physical disabilities, because the movement of the leg or arm that triggers the mechanism is done vertically, in other words, the movement is down, up, down, first class. Background technique [0004] Several devices already exist which move gears fitted in bicycles or other pedal-powered vehicles by means of cranks, usually triggered by pedals. [0005] However, there is no such device as the invented device because it is able to...
