A vehicle includes a truck bed side panel, a top cover, a clamp, and a plug. The truck bed side panel has a top defining a stake pocket and an overhang extending from the top. The top cover has an upper surface defining an aperture. The clamp is secured to the top cover and engages the overhang to secure the top cover to the top of the side panel. The plug is disposed within the stake pocket and aperture to prevent slippage of the top cover.

The present invention relates generally to a tarp systems, in particular, to improvements to various aspects of a tarp tensioning system. The tarp tensioning system has a plurality of frames, the frames having two or more bow members and a biasing mechanism coupled therebetween to maintain tension on the tarp.

In one embodiment, there is disclosed a snap fit extender fashioned from an elastic body material of a predetermined length with male and female snap fits at opposing ends of the elastic body in directionally opposite facing relation to each other. The snap fittings on the extender are cooperatively engageable to complimentary snap fittings on a cover and a vehicle and responsive to dimensional changes to the cover occasioned by weather or age related shrinkage without inducing harmful stresses into the cover.

A tonneau cover system for covering a space. The system includes a frame having rails. A cover is disposed over the frame for covering the space. A block, a receiver, an anchor and a latch are all coupled to the frame. A mechanism is disposed between the block and the receiver and provides adjustment to the frame by moving the receiver, the anchor and the latch as a unit between an initial adjustment position and a final adjustment position. The mechanism also provides tension to the cover when the latch is engaging the frame.

The disclosed safety device helps prevents the dog from falling from, being thrown from, or jumping from the back of a pickup truck by securing them with a safely attached net to the truck racks. The net grids (openings) are sized to either allow or prevent the dog from getting just their heads through the net. The net is easily removable for tall cargo and it also allows you to carry cargo that normally needs to be secured to the truck bed itself or in a truck with a cap. The cargo can be such as; commercial and residential construction material, yard debris, and sporting goods.

A two-piece tarp fastener device for fastening tarps together includes a male coupler and a female coupler. The male coupler comprises includes a rod that has a first end and a second end. A knob is coupled to the first end of the rod. A pin is positioned in the rod proximate to the second end. The pin has opposing ends that extend from an outer surface of the rod. The female coupler comprises includes a tube that has a first terminus and a second terminus. The tube is hollow and complimentary to the rod. A button is coupled to the first terminus of the tube. A pair of slots, complimentary to the pin, is opposingly positioned in a wall of the tube. The slots extend from the second terminus to proximate to the first terminus. Each slot has a channel that extends transversely from a respective bottom of the slot.

A pair of tension adjustment blocks can include one or more positioning members receivable in the tension adjustment block mounting aperture to define a selected one of a plurality of distances from the aperture to a corresponding end of the tension adjustment block. When the tension adjustment blocks are selectively arranged in one of a plurality of orientations with one of the positioning members inserted into the tension adjustment block mounting aperture of each of the side rails to define a selected distance, the corresponding end of each tension adjustment block retains a header at a selected fore/aft position related to the selected distance that is different from the other adjustment tension adjustment block orientations and related distances.
