U.S. Pat. No. 125,451
Inventor: Solon A. Gregg
Issued: Apr. 9, 1872
The invention for its object to furnish an improved velocipede-wagon simple in construction and convenient in use, being so constructed as to adapt it for use upon common roads.
U.S. Pat. No. 844,319
Inventor: Alexander M. Bollinger
Issued: Feb. 19, 1907
The object of the invention is to provide a comparatively simple and inexpensive vehicle having a hand lever pivotally mounted for lateral movement on the supporting frame and operatively connected with the drive mechanism whereby motion may be transmitted to the rear axle of the vehicle when the hand lever is operated.
U.S. Pat. No. 1,190,089
Inventor: John W. Bellairs
Issued: Jul. 4, 1916
The invention aims primarily to provide a velocipede so constructed that the operator may stand upon operating levers while steering, to the end that the entire weight of the operator may be made effective to actuate the levers.
U.S. Pat. No. 1,686,389
Inventor: Bert B. Martin
Issued: Oct. 2, 1928
The invention relates to an improved toy vehicle of the type including a platform on which the occupant rides while in standing position, the platform being suspended close to the surface, in order that it may be readily mounted or dismounted while moving.
U.S. Pat. No. 1,788,774
Inventor: Joseph Matushak
Issued: Jan. 13, 1932
This invention relates to vehicles and more particularly to a child's vehicle of the type known as a scooter and may be propelled forwardly by means of a mechanism including a pedal.
U.S. Pat. No. 1,867,731
Inventor: Herman E. Clarke
Issued: Jul. 19, 1932
The present invention relates to improvements to wheeled toys which are particularly adapted for use by small children. The object of the invention is to provide a toy which will give healthy exercise to a child and enable him to simulate a movement such as that of riding a horse and to utilize the movement and effort to propel the toy.
U.S. Pat. No. 2,123,390
Inventor: John M. Welch
Issued: Jul. 12, 1938
A device is provided that relates to scooters and a propelling or drive means therefor, which is simple and easy for a child to actuate for permitting the child to ride the device entirely free of the ground and to utilize the steering handle bar for driving the front wheel of the device.
U.S. Pat. No. 2,544,996
Inventor: Rudolf Kander
Issued: Mar. 15, 1951
This invention relates to improvements in scooters, the type of wheeled vehicle which children propel through force applied with one foot on the surface on which the scooter travels and with the other foot and body weight normally supported on the low platform of the vehicle and provides for foot-power propulsion applied through a treadle to forcibly drive the rear wheel of the vehicle. The object of the invention is to provide a scooter with treadle-operable drive, and an over-running or free-wheeling clutch.
U.S. Pat. No. 3,149,857
Inventor: George May
Issued: Sep. 22, 1964
This invention relates to a novel and useful amusement vehicle which is adapted to be propelled by a child by means of a driving connection with a drive wheel of the vehicle which is perhaps most commonly known for its use in the construction of an Irish Mail type of vehicle.
U.S. Pat. No. 3,175,844
Inventor: George Whitehouse
Issued: Mar. 10, 1965
The invention relates to scooters with an improved driving mechanism for treadle type scooters. The child standing with one foot upon the platform engages the treadle with the opposite foot for propelling the scooter forwardly, without necessarily pressing the foot upon the surface over which the scooter is moving.
U.S. Pat. No. 4,582,342
Inventors: Hyon Lew and Yon K. Lew
Issued: Apr. 15, 1986
This invention relates to a self-propelled roller board that provides mobility for people in downtown areas, campuses and neighborhood localities. The pediroller board comprises one or two free-wheeling front wheels steerably affixed to an oblong board near one extremity thereof and a pair of rear wheels affixed to the oblong board near the other extremity wherein the rear wheels are driven by a pedal-powered gear driving a pinion gear including a ratchet drive driving the axle of the rear wheels. A person riding the pediroller board balances oneself by standing with one foot placed on the front portion of the oblong board and by holding a joystick type steering lever and propels the pediroller board by pedaling a pedal disposed near the rear extremity of the oblong board wherein the up-and-down motion of the pedal is converted to the rotating motion of the drive gear by a crank mechanism.
U.S. Pat. No. 4,761,014
Inventor: Kung Huang
Issued: Aug. 2, 1988
A scooter of an ordinary general shape but equipped with an improved mechanical drive for the rear wheel or wheels, which drive is comprised of a ratchet mechanism for driving the rear wheel, a stepping lever for transferring the stepping force of the rider to the ratchet mechanism and a retrieving means for raising the stepping lever to the original position as the stepping force is released therefrom; whereby, the scooter can be propelled by the intermittent force of the rider to advance forwardly.
U.S. Pat. No. 4,846,488
Inventor: Andrzej Szadkowski
Issued: Jul. 11, 1989
A spring drive and a spring drive scooter for use by an operator. The spring drive and spring drive scooter have a frame, a resilient member connected to the frame, a pedal, and a movement. The pedal is supported by the resilient member. The pedal is disposed to bear the operator. The pedal is capable, together with the operator, of oscillatory motion relative to the frame in response to at least roughly periodic impulses supplied to the pedal by the operator at a range of frequencies including a resonant frequency. The movement is connected to the frame and includes a final driven member. The movement is actuated by reciprocation of the pedal, and the movement is capable of converting oscillatory motion of the pedal into circular motion of the final driven member.
U.S. Pat. No. 5,492,345
Inventor: Leszek Kruczek
Issued: Feb. 20, 1996
Spaced frame rails mount a U-shaped frame therebetween, wherein the U-shaped frame is pivotally mounted relative to a first axle mounting a first wheel at a first end of the side rails, with a second axle mounted at the second end of the side rails supporting a second wheel. The side rails include extension legs extending from the side rails mounting a spool axle, with the spool axle mounting a first spool wheel that is mechanically coupled to the U-shaped support frame by means of
