The present invention relates to the field of bicycle, and more particularly, the present invention relates to a chainless bicycle that uses a gear arrangement for driving the drive shaft for converting reciprocal human motion into linear vehicular translation.
BACKGROUND ART
[0002] The use of bicycle structures is known in the prior art. Conventional bicycle drives utilize a chain drive composed of a chain and sprockets to thereby transfer motion from the pedal crank to the rear wheel of the bicycle. A number of problems may be associated with these bicycle chains. They are subject to slippage if the length of the chain is not correctly adjusted. Because the chains are often at least partially exposed, clothing, grass, or other objects may become caught in the chains as the chains move past the objects. In addition, dirt and foreign matter can become lodged on the chain links and decrease the efficiency of the chain mechanism. The chain and sprocket mechanism also must be frequently to keep it moving smoothly.
[0003] The available chainless bicycles are not economical, accurate and time efficient. Further, the available chainless bicycles are not user friendly as these bicycles are complex in structure. Some of the bicycles are not effectively used for remote locations.
[0004] Following are some of the attempts made to design the chainless bicycle for enhancing a rider’s comfort.

[0037] The present invention provides a chainless pedal bicycle for enhancing a rider’s comfort. The bicycle is economical. The bicycle provides a comfort to the rider. The bicycle is energy efficient. The bicycle uses simple mechanism.
[0038] From herein afterwards, a transition mechanism is referred as a mechanism (100). Referring now to the figure 1, the bicycle includes a frame, a pair of wheels, a handle, a pair of pedals and the transition mechanism (100).
[0039] The pair of wheels is rotatably configured with the frame. The wheels are configured one after another as a front wheel and a rear wheel. The front wheel moves freely. The rider’s motion is provided to the rear wheel.
[0040] The handle is configured with the frame. The handle allows a rider to direct the front wheel. The handle is movably connected with the front wheel. When a force is applied either by a left or a right hand, the handle turns about a handle axis thereby the front wheel changes the direction. When the force is applied by a left hand, the handle turns about the handle axis towards the left side thereby the front wheel moves towards the left side. When the force is applied by the right hand, the handle turns about the handle axis towards the right side thereby the front wheel moves towards the left side.
[0041] Referring now to the figure 1, the pair of pedals is rotatably configured with the frame. The pedals receive motion from the rider for driving the bicycle. The pedal moves when the force is applied on each pedal alternatively in a clockwise direction. The rider is allowed to apply the force using the foot. The left foot is used to apply force on a first pedal. The right foot is used to apply force on a second pedal.
[0042] The motion received from the rider is transferred to the rare wheel. The transition mechanism (100) transfers the motion received from the pedal to the rare wheel. In the present invention, the transition mechanism (100) used is a gear arrangement.
[0043] The transition mechanism (100) includes a driving gear, an axel with an axel bevel gear and a main shaft. The pair of bearings is mounted on the shaft. A length of shaft is adjustable between the front wheel and the rare wheel. The shaft is hollow inside. The transition mechanism (100) is provided with a covering. The covering protects the mechanism (100) from the external factors such as dust, dirt, mud and rusting elements present in the environment.
[0044] The driving gear is fixed centrally on a pedal shaft. As shown in figure 2, the main shaft is having a first bevel gear and a second bevel gear. The first bevel gear is arranged at a first end. The first bevel gear meshes with the driving gear. The first bevel gear receives motion from the driving gear perpendicularly. The second bevel gear arranged at a second end. The second bevel gear meshes with the axel bevel gear. The second bevel gear transfers motion to the axel bevel gear perpendicularly. The axel is a shaft of the rare wheel that allows rear wheel to rotate. The axel with the axel bevel gear at one end rotates the rear wheel.
[0045] The pair of pedal includes a first pedal arm and a second pedal arm. The first pedal arm connects the first pedal with the pedal shaft. The second pedal arm connects the second pedal with the pedal shaft. The first and the second pedals are rectangular.
[0046] The bicycle is provided with a pair of brakes for controlling speed of each wheel separately. A lever of each brake is configured near a handle rest at each end of the handle.
[0047] In one more alternative embodiment, the transition mechanism (100) includes a multiple gear arrangement and a gear switching facility. A lever is provided for switching the axel bevel gear meshed with the second bevel gear.
[0048] In a given example, the rider needs to ride on the bicycle and maintain the balance. The force is applied on the first pedal using the left foot, thereby the first pedal arm fixed to the pedal shaft rotates the pedal shaft. The rotation of the pedal shaft rotates the driving gear mounted thereon. The driving gear thereby rotates the first bevel gear. The rotation of the first bevel gear rotates the main shaft and the second bevel gear mouthed thereon. When the second bevel gear rotates the axel bevel gear meshed therewith. The axel rotates the rare wheel mounted thereon.
[0049] The present invention provides an advantage of providing the chainless pedal bicycle for enhancing a rider’s comfort. The bicycle is economical. The bicycle provides a comfort to the rider. The bicycle is energy efficient. The bicycle uses simple mechanism (100).
