Abstract
Abstract A trailer is provided including an elongated longitudinally extending frame incorporating longitudinally aligned and extending front and rear frame sections pivotally secured together at adjacent ends for free relative angular displacement about a horizontal transverse axis. The front end of the front frame section includes coupling structure for coupling the frame to a towing vehicle and the rear frame section includes a transverse axle assembly mounted from the rear frame section centrally intermediate its opposite ends and having a pair of opposite side ground engaging support wheels journalled therefrom. Further, the rear frame section includes structure for support and cradling the lower periphery of the rear wheel of a motorcycle in position rearward of the axle assembly and the front frame section of the trailer includes motorcycle front wheel supporting and cradling structure supported therefrom for adjustable shifting longitudinally of the front frame section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
A motorcycle trailer including a longitudinal main frame incorporating elongated, longitudinally extending end aligned front and rear frame sections with the rear end of said front section pivotally connected to the front end of said rear section for free relative angulation of said sections about a first horizontal transverse axis, said rear section including opposite side ground engaging wheels journalled therefrom for rotation about a second horizontal transverse axis disposed centrally intermediate the front and rear ends of said rear frame section, first motorcycle front wheel support and positioning means carried by said front frame section centrally intermediate the front and rear ends thereof for support of a motorcycle front wheel from said front frame section, motorcycle rear wheel support and positioning means carried by said rear section rearward of said second horizontal axis and coupling means pivotally mounted from said front end of said front section for oscillation relative thereto about a third horizontal axis extending transversely of said front section, said coupling means including a mounting portion mountable relative to a towing vehicle for oscillation relative thereto about an upstanding axis disposed generally normal to said third axis, inwardly swingably retractable laterally outwardly projecting opposite side anchor arms pivotally supported from opposite side longitudinal mid-portions of said front section for angular displacement relative thereto about upstanding axes and including outer ends to which anchor straps may be secured.
Claim 2
Dependent Claim
230 words
A motorcycle trailer including a longitudinal main frame incorporating elongated, longitudinally extending end aligned front and rear frame sections with the rear end of said front section pivotally connected to the front end of said rear section for free relative angulation of said sections about a first horizontal transverse axis, said rear section including opposite side ground engaging wheels journalled therefrom for rotation about a second horizontal transverse axis disposed centrally intermediate the front and rear ends of said rear frame section, first motorcycle front wheel support and positioning means carried by said front frame section centrally intermediate the front and rear ends thereof for support of a motorcycle front wheel from said front frame section, motorcycle rear wheel support and positioning means carried by said rear section rearward of said second horizontal axis and coupling means pivotally mounted from said front end of said front section for oscillation relative thereto about a third horizontal axis extending transversely of said front section, said coupling means including a mounting portion mountable relative to a towing vehicle for oscillation relative thereto about an upstanding axis disposed generally normal to said third axis, inwardly swingably retractable laterally outwardly projecting opposite side anchor arms pivotally supported from opposite side longitudinal mid-portions of said front section for angular displacement relative thereto about upstanding axes and including outer ends to which anchor straps may be secured.
Claim 3
Dependent Claim
47 words
The trailer of claim 1 wherein said first motorcycle front support and positioning means includes an upwardly opening cradle member mounted from said front section for adjusted shifting longitudinally therealong and in which cradle member the lower peripheral portion of a motorcycle front wheel may be cradled.
Claim 4
Dependent Claim
27 words
The trailer of claim 1 wherein said mounting portion includes a vertical mounting shank defining said upstanding axis relative to which said coupling means is angularly displaceable.
Claim 5
Dependent Claim
71 words
The trailer of claim 3 wherein said coupling means includes a circular plate through the center of which said mounting shank extends and adapted to overlie the upper surface of an apertured horizontal flange portion of a towing vehicle through which said mounting shank may extend, and a second circular plate having a central opening formed therein through which said shank extends and is secured for underlying said horizontal flange portion.
Claim 6
Dependent Claim
38 words
The trailer of claim 1 wherein said anchor arms and front section include means for releasably anchoring said anchor arms in outward projecting extended positions against angular displacement relative to said front section toward inwardly swung retracted positions.
Claim 7
Dependent Claim
27 words
The trailer of claim 5 wherein said mounting portion includes a vertical mounting shank defining said upstanding axis relative to which said coupling means is angularly displaceable.
Claim 8
Dependent Claim
71 words
The trailer of claim 6 wherein said coupling means includes a circular plate through the center of which said mounting shank extends and adapted to overlie the upper surface of an apertured horizontal flange portion of a towing vehicle through which said mounting shank may extend, and a second circular plate having a central opening formed therein through which said shank extends and is secured for underlying said horizontal flange portion.
Claim 9
Dependent Claim
78 words
The trailer of claim 1 said rear section includes a pair of opposite side elongated frame members between which a plurality of transverse brace members extend and are secured, said brace members being laterally spaced apart longitudinally of said rear frame section, said rear wheel support and positioning means comprising one adjacent pair of said transverse brace members of said rear frame section between which the lower periphery of the rear wheel of a motorcycle may be cradled.
