Abstract

Abstract A three-wheel velocipede includes a relatively stiff frame having a base portion with converging and diverging side rails for supporting wheels and a seat and a superstructure of triangular components. A pedal crank for powering the velocipede is positioned on the superstructure in front of the seat at a height approximately the height of the seat. A back rest is provided so that a rider pushes against his back as he pedals. In addition, provision is made for pedaling the velocipede backwards so that it will move in reverse.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 271 words
A three-wheel velocipede with a rear driving wheel driven by a sprocket and a pair of front steering wheels, the velocipede comprising: a frame having a base for supporting the wheels and a superstructure for supporting a crank with a sprocket for driving a chain which is trained around the rear wheel sprocket, steering gear with a steering column, and a seat with a back rest, the seat resting on top of the base; said base having a pair of side rails which converge from the front end of the velocipede toward a middle section thereof and diverge from the middle section to the rear end of the vehicle, said side rails forming a fork for supporting the axle of the rear wheel between the rails, said base further including a plurality of bracing tubes a first of which extends between the side rails at the front end thereof, a second of which extends between the side rails intermediate the front end and middle section, and a third which extends between the side rails just forward of the rear wheel; said superstructure including a single, inverted, V-shaped stanchion for supporting the crank, the stanchion having one leg connected to the second tube and the other leg to the middle section of the frame; a pair of inverted U-shaped supports for supporting the back rest of the seat each support having one leg connected to the frame adjacent the third brace and the other leg connected at the rear end of the base; and a second stanchion projecting upwardly from the middle section of the base for journaling the steering column therein.
Claim 2
Dependent Claim 271 words
A three-wheel velocipede with a rear driving wheel driven by a sprocket and a pair of front steering wheels, the velocipede comprising: a frame having a base for supporting the wheels and a superstructure for supporting a crank with a sprocket for driving a chain which is trained around the rear wheel sprocket, steering gear with a steering column, and a seat with a back rest, the seat resting on top of the base; said base having a pair of side rails which converge from the front end of the velocipede toward a middle section thereof and diverge from the middle section to the rear end of the vehicle, said side rails forming a fork for supporting the axle of the rear wheel between the rails, said base further including a plurality of bracing tubes a first of which extends between the side rails at the front end thereof, a second of which extends between the side rails intermediate the front end and middle section, and a third which extends between the side rails just forward of the rear wheel; said superstructure including a single, inverted, V-shaped stanchion for supporting the crank, the stanchion having one leg connected to the second tube and the other leg to the middle section of the frame; a pair of inverted U-shaped supports for supporting the back rest of the seat each support having one leg connected to the frame adjacent the third brace and the other leg connected at the rear end of the base; and a second stanchion projecting upwardly from the middle section of the base for journaling the steering column therein.
Claim 3
Dependent Claim 38 words
The three-wheel velocipede of claim 1 wherein the inverted V-shaped stanchion for supporting the crank positions the crank substantially level with the top of the seat whereby the rider pushes his back against the seat as he pedals.
Claim 4
Dependent Claim 16 words
The three-wheel velocipede of claim 2 wherein reverse means are provided for pedaling the velocipede backwards.
Claim 5
Dependent Claim 35 words
The three-wheel velocipede of claim 3 wherein the reverse means includes an additional sprocket driven by said crank, an additional sprocket attached to the rear wheel, and an additional chain for driving the rear wheel.
Claim 6
Dependent Claim 18 words
The velocipede of claim 1, 2, 3 or 4 wherein the seat includes a compartment therein for storage.
Claim 7
Dependent Claim 20 words
The three-wheel velocipede of claim 1 wherein the steering column is journaled through the V-shaped stanchion which supports the crank.
