FIELD OF THE INVENTION The present invention relates to a cover, and more particularly to a flexible cover to overlie an area peripherally bounded by a plurality of elements which cooperate with the cover to mount it in position.

2. DESCRIPTION OF THE PRIOR ART Attachment of the periphery of a flexible cover to overlie an area of predetermined dimensions presents no difficulty when the peripheral openings in the cover exactly match the locations of the complemental fastener elements bounding the area in question. However, a precise match requires care and skill.

The present invention has particular application to the fitting of canvas or vinyl coated fabric to the open bed of a light commercial vehicle of the type sometimes referred to as a pickup truck. In the prior art it was common practice to provide a plurality of reinforced openings in the periphery of the cover, precisely locate a plurality of complemental fasteners on the truck afterbody, and then fit the fasteners through the cover openings. If the match between any fastener and its opening was off by approximately one-eighth inch or more the fit was unsatisfactory. Therefore, an almost exact match was necessary, which entailed considerable time, skill and consequent expense. Moreover, any stretching or distortion of a cover after a period of use could also render the fit unsatisfactory. An additional problem with such a cover was that it was difficult to stretch taut without eventually tearing the edges of the cover.

SUMMARY OF THE INVENTION According to the present invention a cover is provided which is adapted to overlie an area of predetermined dimensions, such as the open bed of a pickup truck or the like. The cover comprises a flexible sheet to conform to the peripheral contours of the open bed, and fastener elements mounted at the open bed periphery are receivable within a plurality of openings provided in the periphery of the sheet.

An elongated retainer is attached to the sheet in position to extend across the sheet openings so that any portion of the retainer can engage an individual fastener element whereby considerable tolerance is provided for lateral misalignment of a fastener element and the center of the opening within which it is disposed. The larger the opening provided, the greater is the tolerance afforded.

The presence of the retainer element allows a handle to be attached for easy pulling upon the flexible sheet to render it taut. The retainer prevents localization of the pulling stresses, spreading them along the adjacent portions of the sheet periphery.

Other objects and features of the invention will become apparent from consideration of the following description taken in connection with the accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, there is illustrated a cover 10 mounted in overlying relation to the open bed 12 of a pickup truck 14. The showing of the truck 14 is merely exemplary and, as will be seen, the cover 10 is adapted to overlie any similar area of predetermined dimensions.

The afterbody of the truck 14 defining the open bed 12 is of conventional construction, including a front wall 16, spaced side walls 18, and a rear wall or tail gate 20.

Fastener elements in the form of headed buttons 22 are spaced about the periphery of the open bed 12 and are secured to the associated walls of the bed by means of sheet metal screws 24 which each extend through a countersunk central opening in the associated button 22 and into the metal material of the walls and tail gate of the truck bed 12, as best seen in FIGS. 3 and 6. The particular spacing between the buttons 22 is not critical to the present invention, typical spacings at the front of the bed being approximately eight inches, with spacings at the sides and rear of the truck bed being about twelve inches. The spacings at the corners may be closer, if desired, to provide a close fit with the cover 10, as will be seen.

The cover 10 comprises a sheet 26 of flexible material such as vinyl coated cotton twill which is preshrunk and water repellent. The sheet 26 is capable of being stretched to a limited extent in order to provide a taut fit. In this regard, the sheet 26 includes a plurality of openings 28 in its periphery. The openings 28 may be reinforced with grommets or the like, if desired, but the material of the sheet 26 is preferably made sufficiently strong that such reinforcement is not necessary. The openings 28 are located in spaced apart relation so as to complementally match the locations of the plurality of buttons 22.

The side and rear margins of the periphery of the sheet 26 are stitched or otherwise secured to a band 30 of corresponding material, as best viewed in FIGS. 4 and 5, to provide a double thickness for reinforcement. In addition, a length of plastic tubing 32 is incorporated between these thicknesses of material to provide a reinforcing welt. Also sandwiched between the two thicknesses is an elongated element or retainer wire or rod 34, both the tubing 32 and rod 34 preferably being stitched in the position illustrated. Sections of the tubing 32 and rod 34 are also similarly incorporated within the front margin of the sheet 26, except that the sheet 26, as best seen in FIG. 3 is formed into an overhanging lip 36 which overlies the front wall 16 of the truck bed 12 to prevent rain or wind from entering under the cover 10.

The rear corners of the sheet 26 are illustrated in FIG. 2 as they would be prior to stitching, that is, a portion of each corner is cut away so that when the con fronting edges of the cut away portion are brought together and sewn, the sewn together section will fit over the associated corner of the truck bed 12.

The openings 28 can be made of any particular size, even as much as two inches in diameter, and the rod 34, or sections thereof, extends across each of the openings 28. Consequently, when the cover is fitted over the truck bed 12, and the buttons 22 are received within the openings 28, the rod 34 is adapted to engage and underlie the headed portion of each button 22, as best seen in FIGS. 3 and 6. The resilience of the material of the sheet 26, as well as the weight of the sheet from one edge to the other, or the wind effect pulling up the cover during movement of the truck 14, tends to maintain good engagement between the rod 34 and the various buttons 22. Since any portion of the rod 34 in one of the openings 28 is effective to engage the associated button 22 in the manner just described, it will be apparent that the centers of the buttons 22 need not exactly align with the centers of the openings 28. Instead, there is a considerable tolerance provided, in that each button 22 can project within almost any part of the opening 28 and be in position to engage upon the rod 34.

The openings 28 and the integral rod 34 associated therewith have been illustrated as located at each ofthe four margins of the sheet 26, but there may be occasions where such an arrangement would be omitted along one or more edges of the sheet. For example, if a more permanent type of fastening arrangement was desired to secure the front margin of the sheet 26 in position, grommeted openings could be provided at the front margin to receive fasteners having projecting portions which can be received in such openings and then turned or moved so as to lock against the margins of such openings, as will be apparent to those skilled in the art. However, in most instances use of the openings 28 and rod 34 about the entire periphery of the sheet 26 is preferred since mounting or removal of the cover 10 require only that the margin or margins of the sheet 26 be pulled sufficiently to unseat or disengage the rod 34 from the heads of the buttons 22.

To facilitate pulling upon the cover margins a plurality of handle holds or handles 38 are provided at spaced intervals along the side and rear margins of the sheet 26, as best seen in FIGS. 2 and 4. Each handle 38 is made of a length of nylon webbing which underlies the cover margins and has its opposite ends disposed through suitable openings in the reinforcing band 30. These ends are looped back upon themselves and stitched so that when the handle is grasped and pulled the strain is transmitted along the length of the associated section of rod 34. This eliminates localized stresses which might tear the margin of the sheet 26.

The cover 10 is easily mounted in position by first locating the front margin openings 28 over the buttons 22, with the rod 34 underlying the undercut or head portion of the buttons. Thereafter, the handles 38 at the rear margin are pulled to stretch the cover over the truck bed 12 for location of the rear margin openings 28 over the buttons 22. Next, one of the side margins is similarly secured in position and, finally, the handles on the opposite side of the cover are used to pull the remaining side margin into position over the buttons Various modifications and changes may be made with regard to the foregoing detailed description without departing from the spirit of the invention.
