Abstract
A cover (10) including a generally L-shaped end plate (20) for stretching and fastening the cover (10) to a frame structure (30). End plate (20) is lockable into a fixed, stretching position with respect to the frame structure (30). Different locking arrangements for accomplishing this are disclosed. Structure (160) is provided for mounting the frame structure (30) to the box of a pickup truck or an equivalent apparatus. Structure is also provided for preventing the cover (10) from ballooning during use.
Claims21
A cover apparatus for covering an opening defined in a structure, such as the bed of a pickup, the apparatus being configurable in an uncovered state wherein the opening is uncovered and a covered state wherein the opening is covered, the apparatus comprising:
- a stretchable cover having a longitudinal axis and a transverse axis, a front end and a back end, and two spaced apart longitudinally extending opposite side edges;
- a frame fixedly positionable about the opening;
- a first fastener disposed on a downwardly facing surface, continuously along substantially the entire length of the opposite side edges of said cover;
- a second fastener disposed on an outwardly facing surface, continuously along substantially the entire length of opposite sides of said rigid frame and detachably fastenable to said first fastener of said cover when said cover is in the covered state, said surface on which said second fastener is disposed being inclined upwardly toward a central longitudinal axis of the cover extending from the back end of the cover to the front end of the cover;
- attachment means for attaching the cover to a front end of the opening;
- means attached to said back end of said cover for stretching said cover and for releasably securing said back end of said cover to said frame;
- stiffener means for holding up the side edges of the cover during the covering process so that the first fastener does not engage the second fastener during the stretching process;
- means for locking said stretching means into a fixed, stretching position with respect to said frame;
- and
- means for releasing said locking means so that said cover may be removed from its position over the opening, said releasing means being hand-actuable, thereby not requiring any special tools to release the cover.
A cover apparatus for covering an opening defined in a structure, such as the bed of a pickup, the apparatus being configurable in an uncovered state wherein the opening is uncovered and a covered state wherein the opening is covered, the apparatus comprising:
- a stretchable cover having a longitudinal axis and a transverse axis, a front end and a back end, and two spaced apart longitudinally extending opposite side edges;
- a frame fixedly positionable about the opening;
- a first fastener disposed on a downwardly facing surface, continuously along substantially the entire length of the opposite side edges of said cover;
- a second fastener disposed on an outwardly facing surface, continuously along substantially the entire length of opposite sides of said rigid frame and detachably fastenable to said first fastener of said cover when said cover is in the covered state, said surface on which said second fastener is disposed being inclined upwardly toward a central longitudinal axis of the cover extending from the back end of the cover to the front end of the cover;
- attachment means for attaching the cover to a front end of the opening;
- means attached to said back end of said cover for stretching said cover and for releasably securing said back end of said cover to said frame, said means including a generally L-shaped end plate having a base portion and a leg portion, the back end of the stretchable cover being permanently attached along a back edge of the leg portion, the base portion pivotally engageable with a protruding stationary lip portion of the frame such that upon forcing down on the leg portion the base portion is made to pivot toward the front end of the cover under the stationary lip portion thereby stretching and fastening the back end of the cover;
- stiffener means disposed proximate the opposite side edges of said cover for preventing the first and second fasteners from contacting each other during stretching of the cover.
A cover apparatus for covering an opening defined in a structure, such as the bed of a pickup, the apparatus being configurable in an uncovered state wherein the opening is uncovered and a covered state wherein the opening is covered, the apparatus comprising:
- a stretchable cover having a longitudinal axis and a transverse axis, a front end and a back end, and two spaced apart longitudinally extending opposite side edges;
- a frame fixedly positionable about the opening;
- a first fastener disposed along the opposite side edges of said cover;
- a second fastener disposed along opposite sides of said rigid frame and detachably fastenable to said first fastener of said cover when said cover is in the covered state;
- attachment means for attaching the cover to a front end of the opening;
- and
- means attached to said back end of said cover for stretching said cover and for releasably securing said back end of said cover to said frame;
- said stretching means comprising a stretching element including a generally L-shaped end plate having a base portion and a leg portion, said leg portion being permanently attached to said back end of said cover, said base portion on an opposite side of said leg portion from said cover, the frame including a protruding, stationary lip portion facing the base portion of the end plate and cooperatively engageable with the base portion of the end plate as the end plate is pivoted about a stationary pivot point between an unfastened position and a fastened position, thereby stretching and fastening said cover in the covered state.
