## Abstract

A scooter with a foot platform, front and rear wheels at the forward and rear ends of the foot platform, and a bearing at the forward end of the platform; a steering column mounting sleeve attached to the bearing, a front wheel drive shaft slidable within the steering column mounting sleeve, a hub extension at the lower end of the steering column mounting sleeve supporting the front wheel, a drive extension having a drive member on the lower end of the front wheel drive shaft, a drive pinion coupled to the front wheel and engaged with the drive member and hand bars at the upper end of the steering column mounting sleeve operable by downward movement to slide the front wheel drive shaft downwardly through the steering column mounting sleeve for driving the front wheel.

## Claims

### Claim 1

A scooter having a foot platform defining forward and rear ends, front and rear wheels at the forward and rear ends of the foot platform, and comprising;
a swingable bearing at the forward end of the platform;
a steering column mounting sleeve attached to the swingable bearing, and being rotatable relative to said bearing, said sleeve defining a lower end and an upper end;
a front wheel drive shaft extending through said steering column mounting sleeve and being slidable therethrough, said front wheel drive shaft having an upper driven end extending from said upper end of said steering column mounting sleeve and having a lower end extending from said lower end of said sleeve;
a hub extension at the lower end of the steering column mounting sleeve for mounting the front wheel;
a drive extension on the lower end of the front wheel drive shaft;
a drive member on the drive extension;
a drive pinion operatively connected to said drive member and coupled to the front wheel through a one-way drive wherein downward movement of the drive extension powers the forward rotation of the front wheel,
hand bars at the upper end of said steering column mounting sleeve connected to said upper end of said front wheel drive shaft by linkage, and being operable to slide the front wheel drive shaft downwardly, through the steering column mounting sleeve and rotating said drive pinion for driving the front wheel forwardly; and,
spring biasing means in said steering column mounting sleeve to urge said front wheel drive shaft and said hand bars upwardly.

### Claim 2 (depends on 1)

A scooter as claimed in claim 1 wherein the hand bars comprise a transverse portion coupled to the steering column mounting sleeve, and rotatable relative thereto, and two hand holding portions displaced at angles to said transverse portion, and moveable through downward and upward arcs.

### Claim 3 (depends on 2)

A scooter as claimed in claim 2 and including a slide limiting pin extending through a slot in the steering column mounting sleeve, and said pin being secured in said front wheel drive shaft whereby sliding of said front wheel drive shaft through said steering column mounting sleeve is limited by the length of said slot.

### Claim 4 (depends on 2)

A scooter as claimed in claim 2 including a cross rod extending between said hand bars, and said linkage being attached to said cross rod.

### Claim 5 (depends on 1)

A scooter as claimed in claim 1 wherein said drive member is a rack gear.

### Claim 6 (depends on 1)

A scooter as claimed in claim 1 wherein said drive member is a chain.

### Claim 7 (depends on 6)

A scooter as claimed in claim 6 including a drive frame attached to said drive shaft, and guide bars on said drive frame, and wherein said chain is attached to said drive frame and is supported thereby in contact with said pinion.
