Pick-up truck box cover
View Patent ↗A cover assembly for a pick-up truck cargo box includes first and second rails attachable at the sides of the box. A cover has a first resilient hinge strip connecting a first panel to a second panel and allowing the first panel to pivot relative to the second panel. A third panel is attached to the second panel by a second resilient hinge strip, which allows the second panel to pivot relative to the third panel. The panels are supported on the rails. Latches on the panels hold the panels onto the rails. The cover may be opened by sequentially releasing the latches and folding the panels over onto each other.
1. A cover assembly for a pick-up truck cargo box having first and second box rails, with each box rail having a top surface, comprising:
first and second side rails attachable to the first and second box rails, respectively;
a cover supported on the first and second side rails, with the cover including a first panel pivotally attached to a second panel, and a front panel pivotally attached to the second panel;
with the first and second side rails each having a panel support joined to a clamp plate, with the panel support below the top surface of the first and second box rails, and offset inwardly from, and not overlying, the first and second box rails, respectively, and with one of more of the panels resting on the panel supports;
a first holding element having a first end attachable to a bottom surface of the front panel, and a second end attachable to the first side rail, adjacent to a front end of the first side rail, for holding the cover in a folded upright position.
2. The cover assembly of claim 1 comprising a second holding element having a first end attachable to a bottom surface of the front panel, and a second end pivotally attachable to the second side rail.
3. The cover assembly of claim 2 further comprising first and second mounting plates on a bottom surface of the front panel, and with the first end of each of the first and second holding elements attachable to the first and second mounting plates, respectively.
4. The cover assembly of claim 2 wherein the holding elements hold the folded cover in an upright and over center position.
5. The cover assembly of claim 1 further comprising a slam latch assembly on a bottom surface of one or more of the panels, with the slam latch assembly including first and second plungers urged outwardly by first and second springs into latching positions wherein the first and second plungers extend at least partially into the first and second side rails, respectively, for latching the panel into engagement with the first and second rails; and
a release mechanism associated with each slam latch assembly for releasing the first and second plungers from the first and second side rails, respectively.
6. The cover assembly of claim 1 with the panel support substantially perpendicular to the clamp plate.
7. The cover assembly of claim 1 further comprising:
first and second extension plates at the front end of the first and second side rails, respectively; and
the front panel attached to the first and second extension plates.
8. The cover assembly of claim 1 further including a first spacer pivotally connecting the second panel to the front panel.
9. The cover assembly of claim 1 wherein the clamp plate extends below the panel support.
10. The cover assembly of claim 1 wherein the clamp plate extends above and below the panel support.
