Abstract
Abstract The device comprises two hinged sections, one section having wheels thereon and the other initially serving as an inclined ramp. With the wheeled section resting on the tailgate or floor of a truck, the snowmobile is first moved onto the ramp section. The ramp section is then raised so that it is horizontal with the wheeled section and the entire device is moved forwardly along the flooring of the truck by means of the wheels so that both the device and snowmobile are fully contained within the box of the truck.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
A device for loading a snowmobile onto a truck comprising first and second rigid sections over which the snowmobile to be loaded may be moved, hinged means pivotally connecting the adjacent ends of said sections together, and a plurality of wheels associated with said first section so that Said first section may be advanced from the tailgate end of the truck forwardly along the floor thereof, said second section having a length sufficient to support thereon at least the major portion of the snowmobile, whereby when said first section is placed in an elevated position on the tailgate or floor of the truck said second section provides an inclined ramp onto which the snowmobile can be first moved so that the second section with the snowmobile thereon can be raised into a generally horizontal or planar relation with said first section in order to permit wheeled advancement of said first section in a forward direction while said second section is maintained in its raised condition with said snowmobile supported thereon.
Claim 2
Independent Claim
170 words
A device for loading a snowmobile onto a truck comprising first and second rigid sections over which the snowmobile to be loaded may be moved, hinged means pivotally connecting the adjacent ends of said sections together, and a plurality of wheels associated with said first section so that Said first section may be advanced from the tailgate end of the truck forwardly along the floor thereof, said second section having a length sufficient to support thereon at least the major portion of the snowmobile, whereby when said first section is placed in an elevated position on the tailgate or floor of the truck said second section provides an inclined ramp onto which the snowmobile can be first moved so that the second section with the snowmobile thereon can be raised into a generally horizontal or planar relation with said first section in order to permit wheeled advancement of said first section in a forward direction while said second section is maintained in its raised condition with said snowmobile supported thereon.
Claim 3
Dependent Claim
31 words
The device of claim 1 in which each of said sections includes a pair of longitudinal elements, and means maintaining each pair of elements in the same laterally spaced parallel relation.
Claim 4
Dependent Claim
53 words
The device of claim 2 in which each of said longitudinal elements has a channel-shaped cross section forming side walls and a connecting bottom wall, the bottom walls of the elements contained in said first section having openings through which segmental portions of said wheels extend for rolling contact with the truck''s floor.
Claim 5
Dependent Claim
44 words
The device of claim 3 in which there is an opening and wheel adjacent each end of each longitudinal element contained in said first section, and a shaft for rotatably mounting each wheel, said shafts being attached to the undersides of said bottom walls.
Claim 6
Dependent Claim
53 words
The device of claim 3 in which said hinge means includes strips secured at one end to the side walls of the longitudinal elements of one section and pivotally connected at their other ends to the adjacent ends of the side walls of the other of said sections at the adjacent ends thereof.
Claim 7
Dependent Claim
44 words
The device of claim 5 in which said second section includes a plurality of longitudinally spaced cross bars extending laterally between its said pair of longitudinal elements for maintaining the lateral spacing of said last-mentioned longitudinal elements and for also initially supporting the snowmobile.
Claim 8
Dependent Claim
25 words
A device in accordance with claim 5 including a chain having its ends connected to the end of said second section remote from said hinges.
Claim 9
Dependent Claim
21 words
A device in accordance with claim 6 including a plurality of rollers extending between the side walls of said channel-shaped members.
Claim 10
Dependent Claim
30 words
A device in accordance with claim 6 including a chain having its opposite ends attached to the cross bar nearest the end of said second section remote from said hinges.
