Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
An operator propelled vehicle comprising: means defining a body having opposite ends; a leaf spring connected to said body and extending obtusely upwardly near one end thereof and supporting the operator''s seat at said end for oscillation; an axle rotatably journalled to the body; ground engaging wheel means mounted on said axle for roTation relative to said body; a ratchet gear concentrically mounted on said axle for rotation with said wheel means; a carrier pivoted about the axle axis for movement of portions thereof between forward and rear positions; two ratchet dogs mounted on said carrier portions on opposite sides of the ratchet gear, each dog having a gear engaging portion and a carrier engaging portion normally urged against said carrier, the ratchet dogs preventing rotation of the wheel means in either direction depending on which gear engaging portion of the respective dogs engages the ratchet gear, one dog being in a position for its gear engaging portion to engage the gear when the carrier portions are in said forward position, the other dog being in a position for its gear engaging portion to engage said gear when said carrier portions are in said rear position; and operating means connected to said carrier for selectively moving said carrier between said forward and rear positions, whereby an operator may selectively determine which direction the vehicle shall move.
Claim 2
Dependent Claim
226 words
An operator propelled vehicle comprising: means defining a body having opposite ends; a leaf spring connected to said body and extending obtusely upwardly near one end thereof and supporting the operator''s seat at said end for oscillation; an axle rotatably journalled to the body; ground engaging wheel means mounted on said axle for roTation relative to said body; a ratchet gear concentrically mounted on said axle for rotation with said wheel means; a carrier pivoted about the axle axis for movement of portions thereof between forward and rear positions; two ratchet dogs mounted on said carrier portions on opposite sides of the ratchet gear, each dog having a gear engaging portion and a carrier engaging portion normally urged against said carrier, the ratchet dogs preventing rotation of the wheel means in either direction depending on which gear engaging portion of the respective dogs engages the ratchet gear, one dog being in a position for its gear engaging portion to engage the gear when the carrier portions are in said forward position, the other dog being in a position for its gear engaging portion to engage said gear when said carrier portions are in said rear position; and operating means connected to said carrier for selectively moving said carrier between said forward and rear positions, whereby an operator may selectively determine which direction the vehicle shall move.
Claim 3
Dependent Claim
44 words
The vehicle of claim 1 wherein said carrier is movable to a middle position by said operating means whereat neither dog is in a position for engagement of its gear engaging portion with the ratchet gear, whereby the vehicle may move in either direction.
Claim 4
Dependent Claim
183 words
In an operator propelled vehicle which includes, means defining a body, an axle mounted on said body, ground engaging wheel means mounted on said axle for rotation to said body, motion restraining means comprising: a ratchet gear concentrically mounted for rotation with said wheel means; a carrier mounted on said axle and movable relative to said ratchet gear between a first position and a second position; pawl means mounted on said carrier and having gear engaging means, said pawl means being in a position for the gear engaging means to engage the gear at one point thereof when said carrier is in said first position for preventing rotation of the wheel means in one direction, said pawl means being in a position for the gear engaging means to engage said gear at another point thereof when said carrier is in said second position for preventing rotation of the wheel means in the opposite direction; and operating means connected to said carrier for moving said carrier between said first and second positions, whereby an operator may selectively determine which direction the vehicle shall move.
Claim 5
Dependent Claim
183 words
In an operator propelled vehicle which includes, means defining a body, an axle mounted on said body, ground engaging wheel means mounted on said axle for rotation to said body, motion restraining means comprising: a ratchet gear concentrically mounted for rotation with said wheel means; a carrier mounted on said axle and movable relative to said ratchet gear between a first position and a second position; pawl means mounted on said carrier and having gear engaging means, said pawl means being in a position for the gear engaging means to engage the gear at one point thereof when said carrier is in said first position for preventing rotation of the wheel means in one direction, said pawl means being in a position for the gear engaging means to engage said gear at another point thereof when said carrier is in said second position for preventing rotation of the wheel means in the opposite direction; and operating means connected to said carrier for moving said carrier between said first and second positions, whereby an operator may selectively determine which direction the vehicle shall move.
Claim 6
Dependent Claim
44 words
The vehicle of claim 3 wherein said carrier is movable to a middle position by said operating means whereat neither dog is in a position for engagement of its gear engaging portion with the ratchet gear, whereby the vehicle may move in either direction.
