Abstract

A topper for the bed of a pickup truck comprises a cover member pivotally supported to one wall of the pickup bed from which the cover member is pivoted between a first position wherein the cover member covers and encloses the bed and a second position wherein the cover member is supported substantially above the bed to provide access thereto. A support arm member is provided with its first end pivotally attached to the opposed side walls of the bed near the rear end of the truck bed. The second end of the support arm member is slidably engaged along the cover member. A spring structure is attached between the cover member and the support arm member and urges the second end of the support member to rotate the support arm member to an upright position. As the support member is rotated upwardly, the rear of the cover member is raised to provide access to the truck bed. In an alternative embodiment, both the front and rear of the cover member are raisable by pivoting front and rear support arm assemblies. In this way, access to both the front and the rear of the pickup truck bed is facilitated. The support arm assemblies are pivotally connected at one end to the pickup bed with the opposite end slidably engaged to the cover member. A spring is attached between the cover member and each of the support arms for urging the upper end of each arm toward the end of the cover member. By so doing, the arm assemblies are rotated upwardly to raise the cover assembly above the bed thereby providing access thereto.

Claims

1. For use in conjunction with a vehicle of the type having a bed including opposed side walls, a front wall and a pivotally supported tailgate and wherein the side walls of the bed have stake holes formed in the tops thereof, a raisable topper assembly comprising:

a cover member extending continuously between side edges spaced apart at least as far as the side walls of the bed and front and rear edges spaced apart at least as far as the front wall and the tailgate of the bed respectively for covering and enclosing the bed of the vehicle;

means for pivotally securing said cover member to the front wall of the vehicle for pivotal movement between a first position wherein said cover member covers and encloses the bed and a second position wherein said cover member is supported substantially above the bed to provide access thereto;

first and second track members attached longitudinally along the underside of said cover member at inwardly spaced positions from said side edges of said cover member;

first and second plug members adapted to slide within said first and second track members;

first and second arm assemblies each having first and second ends, said first ends of said first and second arm assemblies being pivotally attached to the vehicle adjacent the tailgate;

a transverse frame member having first and second ends, said frame member ends interconnecting said second ends of said first and second arm assemblies to form a substantially U-shaped unitary supporting structure for said cover member in said second position;

means mounted to said transverse frame member at points spaced interior of said frame member first and second ends for pivotally engaging said first and second plug members;

first compression spring means having first and second ends and contained within said first track member, said first end of said first spring means being attached to said first plug member and said second end of said first spring means being attached to a point on said cover member remote from said rear edge of said cover member;

second compression spring means having first and second ends and contained within said second track member, said first end of said second spring means being attached to said second plug member and said second end of said second spring means being attached to a point on said cover member remote from said rear edge of said cover member;

said first and second arm assemblies being maintained at a predetermined angle with respect to the top of the side walls of the vehicle and biased by said first and second compression spring means when said cover member is in said first position; and

said first and second compression spring means being operable to simultaneously bias said first and second arm assemblies for urging said second ends of said first and second arm assemblies towards the tailgate of the vehicle to thereby simultaneously rotate said first and second arm assemblies to an upright position to raise said rear edge of said cover member to said cover member second position to provide access to the bed of the vehicle.

2. The topper according to claim 1 wherein said cover member is further characterized by sealing means for engaging the side walls of the bed for sealing the bed when said cover member is in said first position.

3. The topper according to claim 1 further characterized by means for selectively restraining the movement of said first and second arm assemblies when said cover member is in said second position.

4. The topper according to claim 1 further characterized by retaining means mounted to said cover member for selective engagement with the side walls of the vehicle to secure said cover member in said first position.

5. The topper according to claim 4 wherein said retaining means comprises:

frame means including spaced, parallel side members positioned for engagement with the tops of the side walls of the bed of the vehicle and a front member extending between the front ends of said side members and positioned to extend along the front wall of the bed; and

means for engagment with the stake holes of the side walls of the bed of the vehicle to secure said frame means thereto.

6. The topper according to claim 5 further characterized by latching means mounted to said cover member for selective engagement with apparatus contained within said side members of said frame means to secure said cover member in said first position.

7. The topper according to claim 6 wherein said side members of said frame means comprise upper and lower walls defining an open space therebetween, and wherein said retaining means is positioned in said open space between said upper and lower walls of said side members of said frame means and extends therefrom into the stake holes of said side walls of the bed to secure said frame means and said cover member to the bed.

8. The topper according to claim 1 wherein said means for pivotally securing said cover member to the front wall of the vehicle comprises piano hinge means secured to the front wall of the vehicle and said cover member and extending substantially the entire length of the front wall of the vehicle.

9. The topper according to claim 1 wherein said first and second arm assemblies are extendable such that said cover member may be further pivoted relative to the front wall of the vehicle when said cover member is in said second position to raise said cover member above the bed.
