Abstract

The utility model relates to a bicycle without pedals. The utility model is composed of general bicycle wheels, a bicycle frame, a handlebar, a saddle, a chain wheel, a chain, ratchet wheels and a drive device. The drive device is arranged below the saddle of the existing bicycle. The utility model does not uses the pedals to drive, but uses rack on a square shaft below the saddle to drive a gear drive the chain wheel, and then uses a sprocket wheel to drive the ratchet wheels on the bicycle wheels to cause the bicycle to run.

Bicycle is as a kind of walking-replacing tool, uses very generally in people's life, also is the most frequently used a kind of vehicle of people.But the bicycle of people's use now, general all is the both feet of personnel selection, pedal by bicycle drives the drive bicycle running, though this type of drive is very convenient, but for leg or the handicapped people of pin, or wearing skirt woman by bike just seems very inconvenient, and this in addition bicycle can only be confined to leg and pin as the motion to human body, can not produce motion to people's waist.

The purpose of this utility model, no matter be to provide a kind of is normal person or disabled person, or the woman who wears skirt rides very convenient, can be to the whole body of human body, particularly waist well moves, and it is laborsaving to ride again, does not have the bicycle of pedal easily.

The bicycle of this no pedal is made up of common wheel 1, vehicle frame 2, handlebar 3, saddle 4, chain wheel 5, chain 6, ratchet 7, pedal 13 and actuating device, it is characterized in that: actuating device comprises that square shaft 8, spring 9, gear 10 and the slideway column 11, the slideway column 11 that are arranged under the saddle 4 are fixed on the vehicle frame 2, be shaped on the square hole that cooperates with square shaft 8 in it, spring 9 is equipped with at the middle part of square shaft 8, its underpart is shaped on tooth bar 12, on tooth bar 12, be engaged with one and be contained in and chain wheel 5 coaxial gears 10, a pedal 3 is housed in the front portion of vehicle frame 2.It is by 12 driven gears 10 of the tooth bar on the square shaft 8, rotates thereby drive chain wheel 5, drives ratchet by sprocket wheel again and makes bicycle running.

The bicycle of this no pedal has rides laborsavingly, comfortable, can make the vehicle, again can be to the whole body of human body, and particularly waist is taken exercise well, is particularly suitable for the handicapped disabled person of leg or pin, or wears advantages such as skirt woman by bike rides.

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing 1 is the structural representation of the bicycle of no pedal.

Accompanying drawing 2 is the structural representation of actuating device.

Wherein: 1 wheel, 2 vehicle frames, 3 handlebars, 4 saddles, 5 chain wheels, 6 chains, 7 ratchets, 8 square shafts, 9 springs, 10 gears, 11 slideway columns, 12 tooth bars, 13 pedals.

The bicycle of this no pedal is a kind of improvement on existing bicycle, is made up of common wheel 1, vehicle frame 2, handlebar 3, saddle 4, chain wheel 5, chain 6, ratchet 7 and actuating device.Removed the pedal of standard bicycle, do not adopt toe clip movable chain wheel and chain to make bicycle running, it is shaped on square hole by a slideway column 11 is housed in the slideway column 11 on the strut bar of the vehicle frame below the saddle 42, a square shaft 8 is housed below the saddle 4, its square hole big or small and in the slideway column 11 matches, spring 9 is housed on the middle part of square shaft 8, and the bottom is shaped on tooth bar 12, is fixed with a gear 10 on the axle of installation chain wheel 5, tooth bar 12 engagements with on the square shaft 8 become actuating device integral body.A pedal 13 is equipped with in the front portion of vehicle frame 2.During use, bicycle is motionless, and the people is sitting in earlier on the saddle 4, and saddle 4 is moved down, and then drives square shaft 8 and moves down, and 12 driven gears of the tooth bar on it 10 rotate, and by chain 6 and ratchet 7 wheel 1 is rotated thereby drive chain wheel 5, makes bicycle running.Also can promote bicycle earlier with both feet moves ahead.After bicycle begins to travel, both feet are placed on the pedal 13, when square shaft 8 moves down into after bottom center, people's body forward is inclined, and the effect of square shaft 8 by spring 9 makes on it and move, and also drives chain wheel 5 and chain 6 counter-rotatings simultaneously, do not influence travelling of bicycle when at this moment, ratchet 7 reverses.When people's health retreats, make square shaft 8 to moving down again, move ahead thereby drive bicycle, reciprocating action can make bicycle be in normal forward traveling like this.Safety, comfortable during this cycling can be to the human body whole body, and particularly waist performs physical exercise, and can make the vehicle again, is particularly suitable for leg or pin has deformity, or the woman who wears skirt rides.
