Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
255 words
A retractable loading chute for a truck comprising: a track including a pair of elongated rail members, said members defining a storage space therebetween, said track adapted to be carried under the bed of said truck and disposed longitudinally thereto, extending from the rear toward the front of the bed; a pair of mutually spaced support members slidably mounted in said track; means cooperating between said support members and said track for retaining said members in said track; a ramp disposed between said support members and carried thereby, said ramp being movable relative to said track between a retracted position wherein said ramp is disposed in the storage space between said rail members and a loading position wherein said ramp is fully withdrawn from the storage space, said ramp having front and rear ends, the planes containing said ends being disposed at angles to the longitudinal axis of said ramp; pivotal connecting means connecting a portion of said ramp longitudinally spaced from the front end toward the center thereof and said support members, for permitting pivotal movement of said ramp relative to said support members into the loading position when said ramp is withdrawn from the storage space, so that when said ramp is withdrawn fRom the storage space and the front portion of said members are retained therein said ramp will pivot about said supporting members into the loading position wherein the rear end of said ramp rests on the ground and the front end thereof abuts the rear end of the truck bed.
Claim 2
Dependent Claim
255 words
A retractable loading chute for a truck comprising: a track including a pair of elongated rail members, said members defining a storage space therebetween, said track adapted to be carried under the bed of said truck and disposed longitudinally thereto, extending from the rear toward the front of the bed; a pair of mutually spaced support members slidably mounted in said track; means cooperating between said support members and said track for retaining said members in said track; a ramp disposed between said support members and carried thereby, said ramp being movable relative to said track between a retracted position wherein said ramp is disposed in the storage space between said rail members and a loading position wherein said ramp is fully withdrawn from the storage space, said ramp having front and rear ends, the planes containing said ends being disposed at angles to the longitudinal axis of said ramp; pivotal connecting means connecting a portion of said ramp longitudinally spaced from the front end toward the center thereof and said support members, for permitting pivotal movement of said ramp relative to said support members into the loading position when said ramp is withdrawn from the storage space, so that when said ramp is withdrawn fRom the storage space and the front portion of said members are retained therein said ramp will pivot about said supporting members into the loading position wherein the rear end of said ramp rests on the ground and the front end thereof abuts the rear end of the truck bed.
Claim 3
Dependent Claim
32 words
The device of claim 1 further comprising releasable means cooperating between said ramp and said track for retaining said ramp in the storage space when said ramp is in the retracted position.
Claim 4
Dependent Claim
20 words
The device of claim 1 wherein said track includes a pair of inwardly opening channels mutually spaced in parallel relationship.
Claim 5
Dependent Claim
15 words
The device of claim 3 wherein said supporting members are slidably received in said channels.
Claim 6
Dependent Claim
29 words
The device of claim 4 wherein said supporting members include outwardly opening channels, each of said supporting channels being received in a rail channel for sliding movement relative thereto.
Claim 7
Dependent Claim
22 words
The device of claim 5 further comprising spacer means connecting said supporting channels for retaining said supporting members in said rail channels.
Claim 8
Dependent Claim
41 words
The device of claim 1 further comprising sidewalls adapted to be mounted on said ramp when said ramp is in the loading position; mounting means carried by said ramp for mounting each of said sidewalls at a side of said ramp.
Claim 9
Dependent Claim
88 words
The device of claim 7 wherein each of said sidewalls comprise a plurality of mutually spaced upright supports and a plurality of mutually spaced lateral supports; means pivotally connecting said lateral supports and said upright supports for permitting movement of said uprights when said walls are mounted on said ramp and said ramp is in the loading position from a first position wherein said uprights are disposed perpendicular to said ramp to a second position wherein said uprights are disposed perpendicular to the plane containing the truck bed.
