Abstract

Abstract A snowmobile trailer has a wheeled supporting frame which is of a U-shaped configuration to straddle the snowmobile body in loading. The frame is swingable, preferably on the axis of a pair of aligned wheels, and has main supporting pads on the outer (rear) ends of the U-frame disposed beyond the axis of swinging and adapted to underlie and support the bottom of the forward part of the body when first tilted downward and then lifted upwardly somewhat. The sides of the frame disposed forwardly of the swinging axis carry adjustable inwardly disposed hold-down members for contacting and applying pressure to longitudinal running board elements on the sides of the snowmobile when the frame is further tilted backwardly from the loading position. Lastly the yoke at the middle of the U-stem (draft connection) has an upstanding fastener which is connected to the draft or trailer element at the rear of the snowmobile, such connection being tensioned by pulling up on the rear of the body.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 338 words
A trailer for snowmobiles of the type which have the following conventional components, to wit, an elongate hull-like body having longitudinal outturned running boards at the sides and having a cross-sectionally convex forward bottom, a pair of parallel skis swivelly mounted for steering at the sides of said bottom, a propulsion powered track extending from the rear of said skis to approximately the rear of said body and supported by a generally horizontal track frame, and a central draft connection means at the rear of said body, said trailer having in combination: an elongate frame of generally U-shape structure having the base portion of the U disposed forwardly with a draft hitch element secured thereto and having longitudinal side portions spaced apart to straddle the widths of conventional snowmobiles, said frame being mounted and swingable upon a pair of spaced wheels revolvable on a transverse axis disposed adjacent the rear end of said U-shaped frame, a pair of horizontally aligned main support pads affixed to the rear portions of said frame sides somewhat rearwardly of said wheels and extending substantially inwardly thereof for engaging the convex forward bottom of said body when the frame is tilted to a position with its rear end close to the ground, a pair of opposed substantially horizontal hold-down and tensioning means affixed respectively to the sides of said frame and extending inwardly thereof and disposed forwardly of said wheel axis for engagement with and above said outturned running boards supplied by the snowmobile when said frame is tilted towards horizontal position from its initial downturned position for engagement with the convex bottom of said body, and an anchoring and tensioning medium including an element affixed to the forward portion of said frame for interlocking with a second element connected centrally with the rear of said body for upward lifting of said body relative to said frame and anchoring of said body in such lifted position thereby also tensioning said frame and said body with said body positioned substantially above original ground-supported position.
Claim 2
Dependent Claim 338 words
A trailer for snowmobiles of the type which have the following conventional components, to wit, an elongate hull-like body having longitudinal outturned running boards at the sides and having a cross-sectionally convex forward bottom, a pair of parallel skis swivelly mounted for steering at the sides of said bottom, a propulsion powered track extending from the rear of said skis to approximately the rear of said body and supported by a generally horizontal track frame, and a central draft connection means at the rear of said body, said trailer having in combination: an elongate frame of generally U-shape structure having the base portion of the U disposed forwardly with a draft hitch element secured thereto and having longitudinal side portions spaced apart to straddle the widths of conventional snowmobiles, said frame being mounted and swingable upon a pair of spaced wheels revolvable on a transverse axis disposed adjacent the rear end of said U-shaped frame, a pair of horizontally aligned main support pads affixed to the rear portions of said frame sides somewhat rearwardly of said wheels and extending substantially inwardly thereof for engaging the convex forward bottom of said body when the frame is tilted to a position with its rear end close to the ground, a pair of opposed substantially horizontal hold-down and tensioning means affixed respectively to the sides of said frame and extending inwardly thereof and disposed forwardly of said wheel axis for engagement with and above said outturned running boards supplied by the snowmobile when said frame is tilted towards horizontal position from its initial downturned position for engagement with the convex bottom of said body, and an anchoring and tensioning medium including an element affixed to the forward portion of said frame for interlocking with a second element connected centrally with the rear of said body for upward lifting of said body relative to said frame and anchoring of said body in such lifted position thereby also tensioning said frame and said body with said body positioned substantially above original ground-supported position.
Claim 3
Dependent Claim 61 words
The structure set forth in claim 1, an elongate restraining medium for disposal in transverse position under the front of said snowmobile and engaging the rear portions of the skis thereof, and means at the ends of said frame sides for tautly anchoring the ends of said restraining medium to prevent said skis from swinging during travel of the loaded snowmobile.
Claim 4
Dependent Claim 35 words
The structure and combination set forth in claim 1 wherein, said inwardly extending support pads are mounted for lateral adjustment upon the sides of said frame for accommodating snowmobiles having hull-shaped bodies of varying widths.
Claim 5
Dependent Claim 38 words
The structure and combination set forth in claim 1 wherein, said hold-down and tensioning means are adjustably affixed to the sides of said frame for lateral adjustment relative thereto and are also offset upwardly from said frame sides.
