Definitions
- the invention relates to reciprocal pedal drive mechanisms generally to the field of sports, recreation, toys, and particularly relates to user-propelled vehicles, such as two- wheel or three-wheel scooter.
- Bicycles and kick scooters are popular human powered vehicles and have been used by most people.
- a scooter includes a frame, pedals adapted to support a user, wheels, steering hand bar, and a geartrain mounted to the wheels.
- the geartrain is adapted to receive a downward force from the pedals, translate a portion of the downward force into a rotational force acting to rotate the wheels in one direction only, and provide an upward return force for the pedals.
- FIG. 1 is a perspective view of a three- wheel scooter.
- FIG. 2 is an overhead sectional view of the gear based pedal return system transmission assembly for the apparatus shown in FIG. 1.
- FIG. 3 is a perspective view of a bike scooter.
- FIG. 4 is an overhead sectional view of the gear based pedal return system transmission assembly for the apparatus shown in FIG. 3
- FIG. 5 is a simple illustration side view of a chain, belt, cable, or other flexible tension member based pedal return system.
- FIG. 1 is a perspective view of a first embodiment of an apparatus in accordance with the invention.
- FIG. 2 is a perspective view of transmission system of the FIG. 1.
- the apparatus includes handle bar 172, upright handle 175, front wheel fork 177, connector 170, front wheel 180, upward walls 168, deck 162, pedal rest platforms 165 and 166, rear wheels 155 and 157, and driving system (FIG. 2).
- the apparatus shown in FIG.1 and FIG.2 is a pedaled scooter propelled by driving two pedals 101 and 102 upward and downward.
- Each of pedals 101 and 102 is adapted to receive a portion of a user's body weight when a user's foot is placed on each of pedals 101 and 102.
- Each of pedals 101 and 102 is also adapted to move between an initial position and a depressed position. The lowest position pedal 101 or 102 can reach is limited by pedal recess platforms 165 and 166.
- the pedaled scooter also includes a geartrain or transmission assembly oriented towards the rear portion of the pedaled scooter that translates downward force on the pedals 101 and 102 to a rotational force on the rear wheel.
- a geartrain can include, but is not limited to, gear-type drives, chain-type drives, belt-type drives, hydraulic-type drives, or other combined drives that translate a downward force into a rotational force.
- crank 103 When pedal 101 is pressed down, crank 103 will turn chain wheel 107 and gear 109 via the crank shaft 105. Gear 109 will engage with gear 110 and turn the shaft 106 in the opposite direction, therefore raise pedal 102 via crank 104.
- Chain wheel 107 will also rotate and pull chain 113 to rotate the fly wheel 115.
- the fly wheel 115 further rotates shaft 125 via one way clutch 121 inside the fly wheel 115. Shaft 125 will further turn chain wheel 130, pull chain 132, and rotate chain wheel 135 and axle 140.
- axle 140 will turn the wheels 155 and 157 via the one way clutches 151 and 152 respectively. Meanwhile, pushing down pedal 101 will make chain wheel 107 and chain wheel 108 to rotate in different direction. But one way clutch 122 in the fly wheel 116 will prevent shaft 125 to engage with the rotation of the fly wheel 116. In general, push down pedal 101 will rotate both wheels 155 and 157, and also raise pedal 102 simultaneously.
- crank shafts 103 and 104 When pedal 102 is pressed down, both wheels 155 and 157 will be rotated, also pedal 101 will be raised. Each of crank shafts 103 and 104 will be rotated within 180° angle. And each of crank shafts 103 and 104 will be rotated by same angle at opposite direction. There is also a one-way clutch or overrun clutch in each of the rear wheels to allow the scooter to coast freely and to turn smoothly.
- the first unidirectional shaft can be used directly as driven wheel shaft or there can be one or multiple shafts for changing speed ration or rotation direction purpose.
- FIG. 3 and FIG. 4 are a perspective view of a second embodiment of an apparatus in accordance with the invention.
- the apparatus shown is a pedaled bike scooter that is propelled by driving two pedals 201 and 202 upward and downward.
- Each pedals 201 and 202 is adapted to receive a portion of a user's body weight or the push force when a user's foot is placed on each pedals 201 and 202.
- Each pedals 201 and 202 is also adapted to move between an initial position and a depressed position.
- the pedaled bike scooter also includes a geartrain or transmission assembly oriented towards the rear portion of the pedaled bike scooter that translates downward force on the pedals 201 and
- a geartrain can include, but is not limited to, gear-type drives, chain-type drives, cable-type drives, band-type drives, hydraulic-type drives, or other combined drives that translate a downward force into a rotational force and at the same time recovery the other pedal.
- crank 204 When pedal 202 is pressed down, crank 204 will rotate chain wheel 208 and gear 210 via the crank shaft 206. Gear 210 will engage with gear 209 and turn the shaft 205 in the opposite direction, therefore raise pedal 201 via crank 203. Chain wheel 208 will also rotate and pull chain 212 to rotate the fly wheel 236. The fly wheel 236 further rotates rear wheel 252. Meanwhile, pushing down pedal 202 will make chain wheel 208 to rotate in the same direction and chain wheel 207 to rotate in different direction. But one way clutch in the fly wheel 235 will prevent the rear wheel to engage with the rotation of the fly wheel 235 or chain wheel 207. In general, push down pedal 202 will rotate rear wheels 252, and also raise pedal 201 simultaneously.
- each pedals 201 and 202 will rotate the rear wheel shaft 234 in the same direction.
- the first shaft converting both pedals' motions to one direction rotation the first unidirectional shaft. Therefore the rear wheel shaft 234 is the first unidirectional shaft in this embodiment.
- crank shaft 203 and 204 will be rotated within 180° angle.
- FIG. 5 shows the gear based pedal recovery system in FIG. 1-4 can also be replaced by chain, cable, band, or other flexible tension members based type recovery system.
- the gears then will be replaced by the wheels with the flexible tension member reversely mounted between two wheels to make the two wheels rotate in opposite direction.
- Flexible tension member 311 is partly circled on wheel 309 and wheel 310.
- Flexible tension member 311 can be chain, belt, cable, or other flexible tension materials. Both ends of the flexible tension member 311 are fixed on the two wheels 309 and 310 by bolts 317 and 317.
- Wheel 309 is fixed on crank shaft 305, and wheel 310 is fixed on crank shaft 306.
- crank shaft 305 When pedal on the crank shaft 305 is pushed down, the rotation of crank shaft 305 will move wheel 309 at the same rotation speed and pull the flexible tension member 311, and further rotate wheel 310 to make the crank shaft 306 to rotate in opposite direction of the crank shaft 305. Therefore, press down the pedal on crank shaft 305 will lift the pedal on crank shaft 306. Similarly, when pedal on crank shaft 306 is pushed down, the crank shaft 305 will be rotated in opposite direction and return the pedal on the crank shaft 305 upward.
- the arrows in FIG. 5 show the related rotations of the wheels when each pedal is pushed down.
