Abstract

Abstract A snowmobile trailer has a ramp which is connectable to the platform and frame assembly in two positions at the rearward end of the trailer for loading two snowmobiles in adjacent storage lanes and is connectable at an angle at two positions adjacent the forward end of the platform and frame assembly for unloading trailers under their own power forwardly of the trailer to both sides of the trailer tongue. A V-shaped deflector above and forwardly of the trailer bed deflects the snowmobile skis as the snowmobile moves forward to steer and guide the snowmobile onto the angularly related ramp for forward unloading. Upturned marginal flanges on the ramp also guide the skis to steer the snowmobile during unloading and loading.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 167 words
A snowmobile trailer comprising a platform and frame assembly said frame assembly including a tongue and hitch for connection to a tow vehicle, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp, and means for selectively connecting said ramp to the rear end of said platform and frame assembly for loading vehicles on said assembly and for connection to the forward end of said platform and frame assembly with the longitudinal centerline of said ramp at an angle extending away from the centerline of said platform and frame assembly to afford unloading of snowmobiles from the forward end of said assembly and with clearance with said tongue and including a deflector located above the platform of said trailer and forwardly of said platform, said deflector being oriented along a line parallel to the centerline of said ramp when said ramp is connected to the forward end of said platform and frame assembly to guide snowmobiles onto said ramp.
Claim 2
Dependent Claim 167 words
A snowmobile trailer comprising a platform and frame assembly said frame assembly including a tongue and hitch for connection to a tow vehicle, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp, and means for selectively connecting said ramp to the rear end of said platform and frame assembly for loading vehicles on said assembly and for connection to the forward end of said platform and frame assembly with the longitudinal centerline of said ramp at an angle extending away from the centerline of said platform and frame assembly to afford unloading of snowmobiles from the forward end of said assembly and with clearance with said tongue and including a deflector located above the platform of said trailer and forwardly of said platform, said deflector being oriented along a line parallel to the centerline of said ramp when said ramp is connected to the forward end of said platform and frame assembly to guide snowmobiles onto said ramp.
Claim 3
Dependent Claim 52 words
A trailer in accordance with claim 1 wherein said deflector is V-shaped with the apex of the V located on the longitudinal center line of said trailer and said platform has two storage lanes with the deflector oriented to divert snowmobiles from the lanes for right and left unloading from said platform.
Claim 4
Dependent Claim 211 words
A snowmobile trailer comprising a platform and frame assembly, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp, said ramp having upwardly extending guide flanges on the side margins of said ramp for engaging and guiding the skis of a snowmobile along a discharge path transverse to the storage position on the trailer, said frame including a forwardly extending frame member, a hitch connected to said forwardly extending frame member and means for selectively and detachably connecting said ramp to the rear end of said platform and frame assembly for loading vehicles on said assembly and for connection to said forwardly extending frame member and said frame assembly with the longitudinal centerline of said ramp at an angle extending away from the centerline of said platform and one of said guide flanges on said ramp extending to proximate the centerline of said platform to engage the skis and divert a snowmobile driven forwardly on said platform with said ramp extending forwardly of said hitch to afford unloading of snowmobiles from the forward end of said trailer and with clearance with a tow vehicle when the centerline of the tow vehicle is at an angle transverse to the longitudinal centerline of said trailer.
Claim 5
Dependent Claim 211 words
A snowmobile trailer comprising a platform and frame assembly, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp, said ramp having upwardly extending guide flanges on the side margins of said ramp for engaging and guiding the skis of a snowmobile along a discharge path transverse to the storage position on the trailer, said frame including a forwardly extending frame member, a hitch connected to said forwardly extending frame member and means for selectively and detachably connecting said ramp to the rear end of said platform and frame assembly for loading vehicles on said assembly and for connection to said forwardly extending frame member and said frame assembly with the longitudinal centerline of said ramp at an angle extending away from the centerline of said platform and one of said guide flanges on said ramp extending to proximate the centerline of said platform to engage the skis and divert a snowmobile driven forwardly on said platform with said ramp extending forwardly of said hitch to afford unloading of snowmobiles from the forward end of said trailer and with clearance with a tow vehicle when the centerline of the tow vehicle is at an angle transverse to the longitudinal centerline of said trailer.
Claim 6
Dependent Claim 175 words
A trailer comprising a platform and frame assembly having a width to accommodate two vehicles, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp to enable loading and unloading of the vehicle under their own power, said ramp having a width less than the width of said platform, said frame including a forwardly extending frame member, a hitch connected to said forwardly extending frame member and means for selectively and detachably connecting said ramp in two loading positions at the rear of said platform to load vehicles in side by side relationship and in two forward unloading positions with the ramp diverging forwardly and outwardly from the platform in each of said forward positions at an angle transverse to the centerline of the trailer and on opposite sides of the centerline and with the ramp affording clearance with a tow vehicle when the centerline of the tow vehicle is at an angle transverse to the longitudinal centerline of said trailer and extending oppositely of the ramp.
Claim 7
Dependent Claim 175 words
A trailer comprising a platform and frame assembly having a width to accommodate two vehicles, wheel means for supporting the frame and platform for travel along the ground, a loading and unloading ramp to enable loading and unloading of the vehicle under their own power, said ramp having a width less than the width of said platform, said frame including a forwardly extending frame member, a hitch connected to said forwardly extending frame member and means for selectively and detachably connecting said ramp in two loading positions at the rear of said platform to load vehicles in side by side relationship and in two forward unloading positions with the ramp diverging forwardly and outwardly from the platform in each of said forward positions at an angle transverse to the centerline of the trailer and on opposite sides of the centerline and with the ramp affording clearance with a tow vehicle when the centerline of the tow vehicle is at an angle transverse to the longitudinal centerline of said trailer and extending oppositely of the ramp.
