Abstract
Abstract A sheet metal cover for truck bodies is disclosed herein and generally comprises a resilient sheet metal member such as stainless steel or the like wound upon a cylindrical member which is rotatably mounted forwardly of the upper portion of the front wall of the truck body. Guide means are provided on the upper ends of the side walls of the truck body for receiving the lateral edges of the sheet metal member therein when the sheet metal member covers the truck body. The guide means define a sinusoidal configuration to provide lateral strength to the sheet metal member when the sheet metal member covers the truck body. A plurality of cylindrical rods are positioned around the cylindrical member and have rollers thereon to rollably contain the sheet metal member when it is wound upon the cylindrical member. The cylindrical member is driven by a reversible motor or the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
In combination, a truck body having rearward and forward ends, spaced apart upstanding side walls extending between said rearward and forward ends, and and open upper end, a horizontally disposed cylindrical member rotatably mounted at the forward end of said truck body, a laterally stiff resilient sheet member wound upon said cylindrical member and having a length sufficient to extend the length of said truck body and a width sufficient to span the space between said side walls, guide means on the upper ends of said side walls for receiving and supporting the side edges of said sheet member at times to permit said sheet member to cover said truck body, and means for rotating said cylindrical member, each of said guide means comprising vertically spaced, substantially horizontally disposed wall members having a sheet metal member receiving area therebetween, the lowermost of each of said wall members of each of said guide means defining a sinusoidal configuration to provide lateral strength to the sheet metal member when said sheet metal member covers said body.
Claim 2
Dependent Claim
174 words
In combination, a truck body having rearward and forward ends, spaced apart upstanding side walls extending between said rearward and forward ends, and and open upper end, a horizontally disposed cylindrical member rotatably mounted at the forward end of said truck body, a laterally stiff resilient sheet member wound upon said cylindrical member and having a length sufficient to extend the length of said truck body and a width sufficient to span the space between said side walls, guide means on the upper ends of said side walls for receiving and supporting the side edges of said sheet member at times to permit said sheet member to cover said truck body, and means for rotating said cylindrical member, each of said guide means comprising vertically spaced, substantially horizontally disposed wall members having a sheet metal member receiving area therebetween, the lowermost of each of said wall members of each of said guide means defining a sinusoidal configuration to provide lateral strength to the sheet metal member when said sheet metal member covers said body.
Claim 3
Dependent Claim
60 words
The combination of claim 1 wherein a plurality of elongated support members are positioned outwardly of said cylindrical member and are parallel to the longitudinal axis thereof, and a plurality of spaced apart rollers rotatably mounted on said support members for rollably containing said sheet member within said support members when said sheet member is wound upon said cylindrical member.
Claim 4
Dependent Claim
17 words
The combination of claim 1 wherein said means for rotating said cylindrical member comprises a motor means.
Claim 5
Dependent Claim
11 words
The combination of claim 3 wherein said motor means is reversible.
Claim 6
Dependent Claim
14 words
The combination of claim 1 wherein said sheet member is comprised of stainless steel.
Claim 7
Dependent Claim
27 words
The combination of claim 1 wherein each of said guide means comprises vertically spaced, substantially horizontally disposed wall members having a sheet metal member receiving area therebetween.
Claim 8
Dependent Claim
14 words
The combination of claim 1 wherein said sheet member is comprised of plastic material.
Claim 9
Dependent Claim
13 words
The combination of claim 1 wherein said sheet member is comprised of metal.
Claim 10
Dependent Claim
203 words
In combination, a truck body having rearward and forward ends, spaced apart upstanding side walls extending between said rearward and forward ends, and an open upper end, a horizontally disposed cylindrical member rotatably mounted at the forward end of said truck body, a laterally stiff resilient sheet member wound upon said cylindrical member and having a length sufficient to extend the length of said truck body and a width sufficient to span the space between said side walls, guide means on the upper ends of said side walls for receiving and supporting the side edges of said sheet member at times to permit said sheet member to cover said truck body, and means for rotating said cylindrical member, each of said guide means comprising vertically spaced, substantially horizontally disposed wall members having a sheet metal member receiving area therebetween, the lowermost of each of said wall members of each of said guide means defining a sinusoidal configuration to provide lateral strength to the sheet metal member when said sheet metal member covers said body, said sheet member having sufficient rigidity so that the rotation of said cylindrical member in one direction will cause said sheet member to move rearwardly over said truck body.
