Abstract
Abstract An extremely compact, low cost, folding motorcycle or motor scooter is provided by means of a novel, rod-like construction. A frame-like chassis defines a compartment for receiving the front and wheel assembly in the folded condition. Portions of the chassis are removable for this purpose. Other portions of the chassis provide pivot means for the front and rear wheel assemblies. The pivot means are skewed at an angle with respect to an axis transverse to the longitudinal axis of the motorcycle so that the front and rear wheel assemblies bypass each other and are in side-by-side relationship in the folded condition. An internal combustion engine is used for the drive means with the seat of the motorcycle preferably being at least partially hollow in order to define a fuel tank. The handle-bar assembly is foldable and is removably keyed to the steering means. The aforementioned abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A folding motorcycle comprising: a. chassis means including a pair of laterally spaced side sections and a plurality of generally transverse rods joining said side sections of said chassis means at the top and bottom thereoF for defining a compartment between said side sections of said chassis means, said bottom rods at the forward and rearward ends of said chassis means being skewed at an angle with respect to an axis that is transverse to the longitudinal axis of the said motorcycle, said forward and rearward rods at the top of said chassis means being readily removable; b. a rear wheel assembly pivotally mounted on said rearward, bottom rod so as to be contained in a skewed position within said compartment when said motorcycle is folded; c. a front wheel assembly pivotally mounted on said forward, bottom rod so as to be contained in a skewed position within said compartment when said motorcycle is folded; d. readily detachable steering means coupled to said chassis and to said front wheel assembly; and e. an internal combustion engine mounted on said chassis and drivingly coupled to said rear wheel assembly.
Claim 2
Dependent Claim
188 words
A folding motorcycle comprising: a. chassis means including a pair of laterally spaced side sections and a plurality of generally transverse rods joining said side sections of said chassis means at the top and bottom thereoF for defining a compartment between said side sections of said chassis means, said bottom rods at the forward and rearward ends of said chassis means being skewed at an angle with respect to an axis that is transverse to the longitudinal axis of the said motorcycle, said forward and rearward rods at the top of said chassis means being readily removable; b. a rear wheel assembly pivotally mounted on said rearward, bottom rod so as to be contained in a skewed position within said compartment when said motorcycle is folded; c. a front wheel assembly pivotally mounted on said forward, bottom rod so as to be contained in a skewed position within said compartment when said motorcycle is folded; d. readily detachable steering means coupled to said chassis and to said front wheel assembly; and e. an internal combustion engine mounted on said chassis and drivingly coupled to said rear wheel assembly.
Claim 3
Dependent Claim
19 words
A motorcycle in accordance with claim 1, wherein said angles of said bottom tubes are equal to each other.
Claim 4
Dependent Claim
17 words
The motorcycle in accordance with claim 1, wherein said angles of said bottom tubes are approximately 5*.
Claim 5
Dependent Claim
18 words
The motorcycle in accordance with claim 1, wherein there is further included a seat secured to said chassis.
Claim 6
Dependent Claim
30 words
The motorcycle in accordance with claim 4, wherein said seat is at least partially hollow and defines a fuel tank that is in fluid communication with said internal combustion engine.
Claim 7
Dependent Claim
92 words
The motorcycle in accordance with claim 1, wherein said steering means is coupled to said chassis by means of a pair of removable, laterally spaced upper rods extending longitudinally and a pair of removable laterally spaced lower rods extending longitudinally, said steering means being coupled to the forward end of said lower rods for pivotal movement about an axis transverse thereto, the rearward end of said longitudinally extending lower rods being coupled to the lower forward end of said chassis for pivotal movement about said skewed axis of said bottom rod thereof.
Claim 8
Dependent Claim
35 words
The motorcycle in accordance with claim 6, wherein there is further included a removable transverse rod for defining a foot rest, said foot rest being mounted on said lower rods proximate the forward end thereof.
Claim 9
Dependent Claim
