US 6,273,491 B1 · Method and apparatus for releasably mounting tonneau covers

Abstract

A tonneau cover is provided which has at least one hinge-mounted latch adjacent the front of the cover, at least one support prop along the side of the cover intermediate the front and rear of the cover, and at least one latch mounted adjacent the rear of the cover, with a pair of independent side rails mounted to the vehicle, at least one of which contains a bracket for releasably receiving the hinge-mounted latch, a support prop receiving bracket cantilevered below and away from the vehicle side wall, and a rear catch bracket for receiving the rearward latch independent of dimensional variations induced from thermal forces over the cover. To facilitate release of the hinge-mounted latch within close confines of the front area of the vehicle bed, a self-contained trip handle is included in the receiving bracket. To prevent the support props from inadvertently damaging the vehicle during installation or removal of the cover, clips are provided to fix the free end of the props to the cover once it is removed from the rail mounted bracket. Dampening magnets or weights are provided to offset thermal expansion of the cover, and leveling nips are provided to offset thermal contraction of the cover. To facilitate proper alignment of the hinge-mounted latch with the rail mounted bracket during installation, a self-centering spring arrangement is provided. Further, to minimize projection of the mounting system away from the vehicle, the rails can be formed to conform to the wall portion of the vehicle portion to which they are mounted.

Dependent claims

An improved arrangement for mounting tonneau covers and the like to the bed of a pick up truck type vehicle, comprising:

first and second spaced-apart front mounting bracket assemblies for releasable attachment of the front portion of the tonneau cover to the vehicle at discrete locations, each such bracket assembly including a rotary latch member mounted on a strap hinge, that strap hinge being secured to the front portion of the tonneau cover, a self-centering bracket member mounted on a rail, that rail being releasably clampable to the of vehicle side wall, and a self-contained trip handle extending from the rotary latch member to selectively disconnect the rotary latch member from the bracket member,
a prop bracket member with means for improved distribution of tonneau cover weight away from the vehicle side wall, including a removable, cantilevered connection of the prop bracket member to the vehicle below the level of the rail and substantially inwardly therefrom,
means for releasably securing the prop to the tonneau when the prop is disconnected from the prop bracket,
at least one rear catch bracket mounted t o a rail with engagement means to accommodate latch alignment in response to longitudinal and lateral thermal expansion of the tonneau cover, that engagement means including an inwardly inclined catch arm for releasable connection to a rear locking member mounted to the tonneau cover,
means for counteracting bowing and sagging of the tonneau cover through the application of counteracting forces during use, including weighted portions intermediate the front and rear of the tonneau cover and leveling nibs along the rails, and
the rails having contoured cross-sectional configurations to closely match the vehicle side wall portion to which the rails abut.
