Vehicles of the aforementioned type are known in the state of the art.
The first disadvantage of the known bicycle is that the rider has to perform with his hands two different tasks in one direction with the hand drive member.
First task: in order to drive the vehicle, the hand drive member must be moved forward and backward in a horizontal direction.
Second task: in order to steer the vehicle, the hand drive member must be turned slightly to the right or left slantwise during the reciprocating movement. This means that, when driving the vehicle, the rider has to continuously exert 100% equal force with his hands to both handles. Otherwise, the front wheel will turn to the right or left, without the rider being able to exert any control or having any choice, and both the rider and the bicycle will fall.
Solution: Newly invented bicycles 2.W do not have this disadvantage. In order to drive the vehicle, the hand drive member must be moved forward and backward in a horizontal direction and, in order to steer, the hand drive member must be turned vertically in the opposite direction. As explained on, the rider can also easily perform the above-mentioned tasks with one hand.
The second disadvantage of the known bicycle is that the hands must push the hand drive forward and pull it backward 100% of the fixed length (completely) in order to maintain the constant movement of the bicycle. Otherwise, the crankshaft cannot pass each 180° (halfway round the circle), which means that pulling back the hand drive member before it has been moved completely forward or backward does not have any effect on the crankshaft rotation and the constant movement of the bicycle.
Solution: Newly invented bicycles 2.W do not have this disadvantage. Because of the first coupling assembly 110 the hands can move the hand drive member in another direction at any time, without this having any further effect on the constant movement of the bicycle (explanation to be found on page 6).
The first disadvantage of the known bicycle is exactly the same as the first disadvantage of the known bicycle 200910017427.1, which has been explained above. The rider has to perform with his hands two different tasks in one direction with the hand drive member.
The second disadvantage of the known bicycle is that the hand drive and foot drive are connected with each other. The hand drive is connected with the crankshaft by means of a rod. In order to drive the bicycle, the hands and feet must continuously work together and can never move individually.
Solution: Newly invented bicycles 2.W do not have this disadvantage. In order to drive the vehicle using the third coupling assembly 310, the hand drive and foot drive can be operated both independently and jointly.
The disadvantage of the known wheelchair is related to the fact that the rod 4 on the crankshaft is connected with the wheelchair wheel by means of a freewheel mechanism. In order to drive the vehicle, the hands must push the hand drive forward and pull it backward 100% of the fixed length (completely). This is exactly the same disadvantage as the second disadvantage of the known bicycle 200910017427.1, which has been explained above.
The first disadvantage of the known bicycle is that the rider has to perform with his hands two different tasks with the hand drive member. This is exactly the same disadvantage as the first disadvantage of the known bicycle 200910017427.1.
The second disadvantage of the known bicycle is related to the construction and operation of the hand drive member. The rider must pull the steering rod upward and push it downward with his hands. This way of operating the hand drive member has exactly the 100% reverse positive property of lever. The shoulders function as the lever shaft and the rider's hands as the lever head. As the hands and shoulders (lever shaft) are wide apart, the rider cannot exert much force to drive the vehicle.
Solution: Newly invented bicycles 2.W do not have this disadvantage as the hand drive member must be moved forward and backward in the horizontal direction.
The disadvantage of the known tricycle is that it does not have constant movement. An operating stroke is made when the hands pull in the hand drive member (towards the chest) and an idle stroke is made when the feet pull out the foot drive member (forward) in the opposite direction. That is why the drive is not constant.
Solution: Newly invented bicycles 2.W do not have this disadvantage because of the first coupling assembly 110. The reciprocating movements of the hand drive member by the hands and the foot drive member by the feet, both independently from each other and jointly, ensure the constant movement of bicycles 2.W.
The disadvantage of the known bicycle is that it does not have constant movement. The bicycle can only be moved when the hands pull in the hand drive member (towards the chest) and an idle stroke is made when the hand drive member is moved in the opposite direction. That is why the drive is not constant. This vehicle does not have a foot drive. Solution: Newly invented bicycles 2.W do not have this disadvantage because of the first coupling assembly 110. The reciprocating movements of the hand drive member by the hands and the foot drive member by the feet, both independently from each other and jointly, ensure the constant movement of the bicycle.
Instead of a piston rod and crankshaft in current motors, the present invention uses the second coupling assembly 210 and/or first coupling assembly 110 of the bicycles 2.W to drive the drive shaft of motors 2. Four examples of the benefits of this system in comparison with current motors:
1-Weight, type of material, construction, operation, parts and connection of the crankshaft and piston rod are expensive.
Solution: Constructing the second coupling assembly is not more expensive than constructing the second coupling assembly 210 or the first coupling assembly 110.
2-Friction: in the current motors, when the motor drive shaft makes one rotation, the inner surface of the valve bush and the outer surface of the crankshaft make contact for a complete rotation and because of the little distance between these two surfaces, the oil lubrication cannot be 100% good.
Solution: One rotation of the drive shaft in motors 2.W is divided between all the teeth of the gears of the second coupling assembly 210. As the parts of the second coupling assembly 210 are located in an oil sump (like the differential gears) the friction is almost nil and the parts work properly for a very long time.
3-Because of the friction between the piston rod and the crankshaft, the oil and oil filter must be replaced every couple of thousand kilometers.
Solution: because of the little friction between the teeth of the gears of the second coupling assembly, the oil can be used for a very long time (like the differential oil) and this system does not need an oil filter.
4-maintenance and replacement of the crankshaft, drive shaft and other parts of the current motors, which usually take place around the same time, are expensive.
Solution: replacement of the gears and parts of motors 2.W is very cheap in comparison with the current motors.
The vehicle comprises a saddle 7 equipped with a back 6. In order to drive the vehicle, it is further equipped with four different hand drives 100-1 to 4 and four different foot drives 200-1 to 4. As will be explained below, both drives can be connected to each other, preferably in such a way that the hand drive 100-1 and foot drive 200-1 can be used both independently and jointly to drive the vehicle.
In the order of bicycles 2.W, the construction and operation of hand drives 100-1 to 4 and foot drives 200-1 to 4 will be described first, then the connection of both drives with the rear wheel, then the steering device, then the connection of the hand drives 1 to 4 with the wheelchair, then the fifth coupling assembly and finally the construction and operation of motors 1 to 4 will be discussed.
The embodiments below are only examples. All types of hand drives and foot drives and motors can be embodied by other assemblies.
According to the present invention in
The hand drive member 4A is at one end fixedly connected with the driving rod 101A and at the other end located in the bush 100A. The bush 100A ensures that the driving rod 101A always remains in its place. The teeth of the driving rod always make contact with the teeth of the underlying gear of the first coupling assembly 110.
The hand drive member 4A is connected with a substantially laterally extending first drive shaft 105 by means of the first coupling assembly 110. The first drive shaft 105 is bearing-mounted, rotatable around its axis, and connected with the bush 100A of the vehicle. The connection between the hand drive member 4A and first drive shaft 105 as established by the first coupling assembly 110 is such that the first drive shaft 105 is driven in the longitudinal direction T and more particularly in one and the same constant forward rotation direction both during the forward and backward movement of the hand drive member 4A. For this purpose, the first coupling assembly 110 can be designed in various ways.
In the present invention, the first coupling assembly 110 comprises a gear assembly. This gear assembly comprises a first gear 102A which is mounted by means of a freewheel mechanism to the first drive shaft 105 in such a way that it can freely rotate around this shaft in a first rotation direction, while it fixedly engages the first drive shaft 105A in a second rotation direction that is opposite to the first rotation direction and carries it in the forward rotation direction. The gear assembly further comprises a second gear 103A which is mounted by means of a freewheel mechanism to the first drive shaft 105 in such a way that it cane freely rotate around this shaft in a second rotation direction, while it fixedly engages this shaft 105 in a first rotation direction and carries it in the forward rotation direction.
The gear assembly further comprises a third gear 104A that is bearing-mounted to the bush 100A of the vehicle, rotatable around an axis extending substantially perpendicularly to the first drive shaft 105, and that interconnects the first gear 102A and second gear 103A in such a way that the first gear 102 always has a rotation direction that is opposite to that of the second gear 103.
In the present invention, the first, second, and third gears 102, 103, 104 of the gear assembly of the first coupling assembly 110 are conical gears with round teeth. The teeth can have various designs, for example spur teeth, etc.
In use, the rider holds the hand drive member 4A of the vehicle. He then stretches his arms, which involves that the teeth of the driving rod 101A are carried over the first gear 102A.
When the first gear 102A runs free in a backward rotation direction, it will engage the first drive shaft 105 when it is driven in the forward rotation direction and carry it in the forward rotation direction. At the same time, the first gear 102A will drive the second gear 103A in its free-running backward rotation direction through the third gear 104A, which has no further effect.
When the rider has pushed the driving rod 101A over a desired distance, the rider pulls his arms towards his chest, which involves that the teeth of the driving rod 101A are carried over the first gear 102A again, but this time in a backward free-running direction. As a result, the second gear 102A is rotated in a forward rotation direction through the third gear 104A, which again has the effect that the first drive shaft 105 is driven in the forward rotation direction.
In short: by moving the hand drive member 4A forward and backward, the first drive shaft 105 remains rotating in a forward rotation direction. Sometimes this is effectuated by the constant forward rotation of gear 102A and sometimes by the constant forward rotation of gear 103A.
The construction and operation of the foot drive 200-1 for driving the second drive shaft 205 are exactly the same as the construction and operation of the hand drive 100-1, as explained above. The only difference is that the foot drive parts are numbered 200B and higher.
In short: by moving the foot drive member 5B forward and backward, the second drive shaft 205 remains rotating in a forward rotation direction. Sometimes this is effectuated by the constant forward rotation of gear 102B and sometimes by the constant forward rotation of gear 103B.
The third coupling assembly 310 is built for driving the vehicle. As has been described above, the first drive shaft 105 is driven by moving the hand drive member 4A forward and backward. By means of the parts of the third coupling assembly 310, numbered 300 to 306, the rotation of the first drive shaft 105 is transferred to the second drive shaft 205 (gear 306 is mounted to the second drive shaft 205 by means of a freewheel mechanism). As has also been described above, the second drive shaft 205 is also driven by the forward and backward movement of the foot drive 5B. The rotation of the first drive shaft and second drive shaft, both independently and jointly, is transferred to the rear wheel 13 by parts 307, 308 and 309 of the third coupling assembly 310 in order to drive the vehicle.
This vehicle is further equipped with a steering device 400-1, as shown in
When the rider turns the hand drive member 4A leftward, the driving rod 101A, key 402A, keyway 401, rod 403A and gear 404A are rotated leftward as well. When gear 404A rotates, gear 406 that is fixedly mounted to the steering housing 407A rotates as well. When the steering housing 407A is rotated, the front fork 8 and front wheel 14 rotate leftward. When the rider turns the hand drive member 4A rightward, all the above-mentioned parts and the front wheel 14 rotate rightward as well.
In the present invention in
The operation and construction of the hand drive 100-2 are similar to those of the hand drive 100-1 as shown in
In order to build an identical version of the first coupling assembly 110, the hand drive member 4Á, driving rod 101Á and bush 100Á are needed in addition to the hand drive member 4A, driving rod 101A and bush 100A. The construction of the gear assembly is the same as that of the hand drive 100-1. The teeth of the first gear 102A make constant contact with the teeth of the driving rod 101A and the teeth of the second gear 103A now make contact with the teeth of the driving rod 101Á. The third gear 104 connects the first gear 103A with the second gear 104A in such a way that the first gear always rotates in a rotation direction opposite to that of the second gear and vice versa.
The construction of an identical version of a foot drive 200-2 is exactly the same as the construction of the hand drive 100-2 (as explained above). The only difference is that the foot drive parts are numbered 200B, 200{acute over (B)} and higher. In order to drive the second drive shaft 205, the rider must move the foot drive members 5B, 5{acute over (B)} forward and backward with his feet.
The construction and operation of the third coupling assembly 310 to drive the vehicle are exactly the same as those of the third coupling assembly 310 of the hand drive 100-1. The explanation can be found on page 8. This vehicle can be driven by both drives independently or jointly.
The steering device 400-2 of
The only difference is that the parts of the second version have the same numbers and numbers followed by Á. Furthermore, parts 450 to 455 are used to connect these twin versions.
When the rider turns the hand drive members 4A and 4Á to the right or left, either independently or jointly, the front wheel 14 is turned to the right or left by the same system/operation of the steering device 400-1 (the explanation can be found on page 8).
In the present invention in
Hand drive 100-3 is identical to hand drive 100-1. The construction and operation of this twin version for driving the first drive shaft 105 are exactly the same as those of hand drive 100-1 (the explanation can be found on page 6).
Foot drive 200-3 is identical to foot drive 200-1. The construction and operation of this twin version for driving the second drive shaft 205 are exactly the same as those of foot drive 200-1 (the explanation can be found on page 7).
In order to drive the vehicle, a third coupling assembly 310 is used in this case as well, the construction and operation of which are the same as those of coupling assembly 310 of hand drive 100-1.
The construction and operation of the steering device of this vehicle are exactly the same as those of steering device 400-2 of
According to the present invention in
Also in this case, hand drive 200-4 is identical to hand drive 100-1. The construction and operation of each hand drive of this twin version for driving the first drive shaft 105 are exactly the same as those of hand drive 100-1 (the explanation can be found on page 6). The construction of the fourth drive is as follows:
Gear 106 is at the rear side permanently connected with gear 104A and gear 107 is at the rear side permanently connected with gear 104Á. Gear 108 (which is connected with bushes 100A and 100Á by means of bearings) ensures that the rotation of gear 106 is transferred to gear 107 and vice versa. If gear 108 is not connected with gears 106 and 107, the vehicle is driven in the other three ways.
The construction and operation of foot drive 200-4 are the same as those of hand drive 100-4, as explained above. The only difference is that the three gears for the fourth way of driving the vehicle are numbered 206, 207, and 208.
Furthermore, in order to drive the vehicle, the third coupling assembly of hand drive 100-1 is used. The construction and operation of the steering device of this vehicle are exactly the same as those of steering device 400-2.
According to the present invention in
As the length of the pedals can be adjusted for people with foot or hand disabilities, for example people with one shorter leg or shorter arm, they can use bicycles 2.W without any problems.
Key 509A is fixedly connected at the bottom side of the telescope 512A and key 509Á´ is fixedly connected at the bottom side of the telescope 512Á (there are no restrictions as to the number of telescopes; this depends on which shape the rider has given to the flexible blade 514). Keys 509A and 509Á are located in keyway 511. Telescopes 512A and 512Á can be moved forward and backward in keyway 511 and can be locked at any location on the keyway. Keyway 511 is fixed at the rear side of bush 200B. The length of both telescopes can only be adjusted and locked vertically. Clamp 513A is fixed at the top of telescope 512A and clamp 513Á is fixed at the top of telescope 512Á. One side of the flexible blade 514 is fixed between both clamps and the other (opposite) side is loosely located between the ball bearings 516A, 516Á of telescope 518 in
Holes 519A, 519Á are located at the side of the driving rod 201B. There are no restrictions as to the number of holes, which allows the rider to lock telescope 518 in any desired hole of the driving rod 201.
Holes 517A, 517Á are fixedly connected with holes 519A, 519Á. Some of the teeth of the driving rod 201B protrude from gap 515A of bush 200B and make contact with the teeth of gear 201B. This fifth coupling assembly is fixed to bush 200{acute over (B)} using the same construction. This system can also be coupled with all other hand and foot drives of bicycles 2.W with the same construction and operation.
In this case, the forward and backward movement of the foot drive member for driving driving rod 201B depends on the shape of the flexible blade 514, which is determined by the feet movements of the rider.
According to the present invention in
Driving the wheelchair using the third coupling assembly for transferring the rotation from the first drive shaft 105 to the rear wheel is effectuated by parts 300 to 304 and 309 (box). The construction and operation are exactly the same as those of the third coupling assembly of hand drive 100-1 of bicycle 2.W.
And steering devices 400-1 and/or 400-2 are used to steer the wheelchair.
These motors can help the rider to drive the vehicle.
In current motors, the drive shaft is driven by a rod and crankshaft.
In motors 2.W according to the present invention in
In motors 2.W according to the present invention in
All motors operate on various fuels.
These motors can be used to drive all bicycles 2.W and to drive the drive shaft of various current motors.
In motors 2.W according to the present invention in
When the sparking plug is contacted by fuel, this motor is standby. When one end of the driving rod 201B makes contact with the cylinder head 601A, an ignition takes place and as a result, the driving rod is moved. When the other end of the driving rod 201B makes contact with cylinder head 601Á, another ignition takes place and the driving rod 201B moves in the opposite direction. The foot drive member 5B that is fixed to the driving rod 201B moves at the same time.
The vehicle is driven by the reciprocating movement of the driving rod 201B and the rotation of the gear 202B and second drive shaft 205. In order to build this motor with two cylinders, the cylinder heads 601A, 601Á are added to both ends of the bush 200B. The other parts for driving the motor-equipped vehicle are the same as those of the foot drive of bicycle 2.W (the construction and operation of the second coupling assembly 210 can be found on page. The driving rod 201{acute over (B)} can also drive the drive shaft of this motor using the same construction and operation.
In order to add multiple cylinders to this motor, a second drive shaft is connected to the shaft of this motor.
Construction of Second Motor 2.W with Two or More Cylinders
In motors 2.W according to the present invention in
The piston 630Á is placed in the driving rod 200{acute over (B)} with the same construction as that of 630A.
Operation of Second Motor 2.W with Two or More Cylinders:
The first ignition at the cylinder head 601A moves the piston and teeth of the driving rod 201B down. As a result, gear 202B is rotated. The rotation of gear 202B moves the teeth at the other side of gear 202B and the teeth of the driving rod 201B and piston 630Á up. The second ignition at the cylinder head 601Á results in a movement in the opposite direction. The negative and positive rotations of gear 202B ensure that the second drive shaft 205 only moves in the forward direction.
In order to add two new pistons, pistons three and four are fixedly connected to the first two pistons in such a way that the teeth of the corresponding drive shafts 201B, 201{acute over (B)} make contact with both sides of gear 204. In order to add two other pistons with the same construction, pistons five and six are fixedly connected to pistons one, two, three and four in such a way that the teeth of the corresponding driving rod 201B, 201{acute over (B)}´ make contact with both sides of a gear that is fixed with a suitable distance at the rear side of gear 203.
In order to add more pistons, multiple gears are fixed with a suitable distance at the rear side to second gear 201B.
Another way of adding more pistons is to connect one end of the second drive shaft 205 of this motor to the second drive shaft of the second coupling assembly 210 or multiple coupling assemblies. Subsequent pistons are connected to previous pistons with the same construction and operation as described above. The ignition time of each two pistons that operate in opposite directions and with one gear may be different from the ignition time of two other pistons.
The reciprocating movement of pistons 630A, 630Á is slowed down or stopped by the hydraulic system 633. The force that is saved in this way is used to move the pistons 630A, 630Á.
According to the present invention in
According to the present invention in
According to the present invention in
This motor has the same construction as the motor in
According to the present invention in
As a result of two ignitions of each piston at the top and bottom side, each piston moves up.
This motor can also be built with more cylinders. Each two cylinders can have different ignition times from the other two cylinders. The hydraulic system 633 slows down the reciprocating movements of all pistons near the end.
Although the present invention was explained hereinabove by some illustrated embodiments, it should be noted that the invention is not limited to these embodiments. A person skilled in the art can make various adjustments and modifications to the described embodiments without leaving the intention and scope of the invention as defined in the following claims.
