A bar lock is described. The bar lock includes a bar. An upper strap is engaged to the bar. The upper strap is configured to engage to an upper hinge butt. A first is roller rotatably engaged to the bar. A lower strap is engaged to the bar. The lower strap is configured to engage to a lower hinge butt. A second roller is rotatably engaged to the bar. A handle bracket is affixed to the bar. A handle is pivotally engaged to the handle bracket. The first and second rollers are configured to prevent or reduce marring or rubbing damage to a door of a cargo area of a truck caused by a racking movement of sides of the truck.

Claims (53)

1 . A bar lock, comprising:

a bar;

an upper strap engaged to the bar, the upper strap configured to engage to an upper hinge butt;

a first roller rotatably engaged to the bar;

a lower strap engaged to the bar, the lower strap configured to engage to a lower hinge butt;

a second roller rotatably engaged to the bar;

a handle bracket affixed to the bar;

a handle pivotally engaged to the handle bracket; and wherein exterior surfaces of the first roller and the second roller are configured to roll against an exterior surface of a door or a ramp; and,

the bar, the upper strap, and the lower strap are configured to pivot or hingedly move relative to the upper hinge butt and the lower hinge butt to urge the exterior surfaces of the first roller and the second roller against the exterior surface of the door or the ramp.

2 . The bar lock according to claim 1 , wherein the first roller and the second roller are generally circular with a central opening.

3 . The bar lock according to claim 2 , wherein the bar passes through the central opening of the first roller and the central opening of the second roller.

4 . The bar lock according to claim 1 , wherein interior surfaces of the first roller and the second roller rotate against an outer surface of the bar.

5 . The bar lock according to claim 1 , wherein the exterior surfaces of the first roller and the second roller are configured to rotate against and roll back and forth relative to the exterior surface of the door or a ramp.

6 . The bar lock according to claim 1 , wherein interior surfaces of the first roller and the second roller includes a groove configured to receive a lubricant.

7 . The bar lock according to claim 1 , wherein the first and second rollers are configured to prevent or reduce marring or rubbing damage to a door or ramp of a cargo area of a truck while still maintaining a closing force or pressure against the door or ramp.

8 . The bar lock according to claim 1 , wherein the first and second rollers are configured to absorb movement of lateral sides or walls of a truck when the truck is driving.

9 . The bar lock according to claim 1 , wherein the first and second rollers are configured to prevent or reduce marring or rubbing damage to a door or ramp of a cargo area of a truck caused by a racking movement of sides of the truck.

10 . The bar lock according to claim 1 , wherein the first roller comprising a central opening, the second roller comprising a central opening, and the bar sized to fit into both of the central openings.

11 . The bar lock according to claim 1 , wherein a first cap fastens to a first end of the bar to secure the first roller to the first end, and a second cap fastens to a second end of the bar to secure the second roller to the second end.

12 . The bar lock according to claim 11 , wherein the first roller is positioned between the first cap and the upper strap, and the second roller is positioned between the second cap and the lower strap.

13 . The bar lock according to claim 11 , the first cap includes a flange portion and an outer portion, wherein the flange portion extends from the outer portion, and the flange portion inserts into a hollow opening of the first end of the bar.

14 . The bar lock according to claim 13 , wherein the flange portion includes one or more ribs that extend outwardly to contact or fit against walls of the hollow opening of the first end of the bar.

15 . The bar lock according to claim 13 , wherein the first roller is positioned between the cap and the upper strap, wherein an outer diameter of the outer portion of the cap is larger than a central opening of the first roller, and the outer portion of the cap holds the first roller to the bar.

16 . The bar lock according to claim 1 , wherein a support is fitted to the handle proximate the handle bracket, and the support includes a contact surface.

17 . The bar lock according to claim 16 , wherein the support includes a semi-tubular shape having an open side and hollow interior to receive the handle.

18 . A truck or trailer comprising the bar lock according to claim 1 .
