Tonneau cover system for a cargo box with side rail end plugs with external mounting extensions
View Patent ↗A side rail can define an exterior channel. A coupling strip can be slidably retained within the exterior channel of the side rail and can be positioned to selectively engage with a coupling strip of a tonneau cover. An end cap can be positioned on an end of the side rail. The end cap can include an exterior tab extension received within the exterior channel, and the exterior tab extension can have an end face positioned within the exterior channel and spaced from a corresponding end of the exterior channel. The end face of the exterior tab extension can be positioned to engage an opposing end face of the coupling strip within the exterior channel to positively limit longitudinal sliding movement of the coupling strip within the exterior channel.

8. The tonneau cover system according to claim 1 , wherein the second coupling strip is slidable within the exterior channel along a main longitudinal axis of the exterior channel.
9. The tonneau cover system according to claim 1 , wherein the end cap comprises two end caps, each positioned on respective opposite ends of the side rail, and wherein the second coupling strip has a length that is less than a distance between the end faces of the end caps.
10. The tonneau cover system according to claim 1 , wherein the side rail comprises two side rails, each of the two side rails being structured for mounting to and extending substantially along a respective opposing lateral side of the cargo box, and wherein the first coupling strip comprises two first coupling strips, each of the two first coupling strips being coupleable to extending substantially along a respective opposing lateral side of the tonneau cover.
11. The tonneau cover system according to claim 1 , wherein the end cap comprises a bumper coupled to a distal end of the end cap.
12. The tonneau cover system according to claim 1 , wherein the side rail is an extruded metal member.
13. The tonneau cover system according to claim 1 , wherein the exterior channel of the side rail extends substantially along an overall longitudinal length of the side rail.
14. A tonneau cover system for covering a cargo box comprising:
a tonneau cover having a first coupling strip extending substantially along each opposing lateral side;
two extruded side rails, each side rail being mounted to and extending substantially along an opposing lateral side of the cargo box, each side rail defining an exterior channel extending substantially along an overall longitudinal length;
a second coupling strip slidably retained within the exterior channel of each side rail and positioned to selectively engage with a respective one of the first coupling strips;
an end cap positioned on an end of each side rail, the end cap including an exterior tab extension received within the exterior channel, the exterior tab extension having an end face positioned within the exterior channel and spaced from a corresponding end of the exterior channel;
wherein the end face of the exterior tab extension is positioned to engage an opposing end face of the second coupling strip within the exterior channel to limit longitudinal sliding movement of the second coupling strip within the exterior channel.
15. The tonneau cover system according to claim 14 , further comprising a retaining fastener extending through the exterior tab extension of each end cap and fixing the end cap to the side rail without the retaining fastener passing through the second coupling strip.
16. The tonneau cover system according to claim 15 , wherein the exterior tab extension of each end cap has a preformed hole therethrough for receiving the retaining fastener, said preformed hole including a recessed portion in an exterior face adjacent the end face to receive a head of the retaining fastener.
17. The tonneau cover system according to claim 15 , wherein the retaining fastener extends through the exterior tab extension of each end cap and through the side rail and into or through an interior extension of the end cap that is received within an interior channel of the side rail.
18. The tonneau cover system according to claim 15 , wherein the retaining fastener is a threaded screw.
19. The tonneau cover system according to claim 14 , wherein each second coupling strip includes two longitudinal sides, each longitudinal side being received within a respective opposing longitudinal slot of the exterior channel to retain the second coupling strip within the exterior channel and exposing a central active coupling element.
