Truck bed cover

Abstract

A truck bed cover includes rails attached along truck bed side tops, slats residing laterally between the rails, end caps attached to opposite ends of each slat sliding forward and rearward in the rails, and flexible joiner hinges attaching consecutive ones of the slats. A cover holder resided between truck sides against a truck cab. The cover slides into the holder for storage, and rolls into a spiral inside the holder. Each slat includes two end walls and a center wall. The center wall includes a center “C” shaped portion and vertical portions reaching up from the center “C” shaped portion to a slat top surface and down from the center “C” shaped portion to a slat bottom surface. The slat top is cambered to reduce or eliminate water pooling on the cover.

DETAILED DESCRIPTION OF THE INVENTION

(15) The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

(16) Where the terms “about” or “generally” are associated with an element of the invention, it is intended to describe a feature's appearance to the human eye or human perception, and not a precise measurement.

(17) A truck 10 and truck bed cover 12 according to the present invention is shown in FIG. 1. The cover 12 slides between rails 18 attached to truck bed side tops 16. The cover 12 is composed of a series of slats 20 which may be pushed into and withdrawn from a cover housing 14 residing against a truck cab 11. The top of the housing 14 is even with the slats 20 or slightly higher than the slats 20 providing a flat surface up to the cab 11. The slats 20 are preferably made from aluminum.

(18) A perspective view of a slat 20 and end cap 46 engaging the side rail 18 is shown in FIG. 2, and a cross-sectional view of slat 20 and the end cap 46 engaging the side rail 18 though a mouth 59 is shown in FIG. 3. A sliding surface 54 (see FIGS. 8-10) of the end cap 46 slides on an insert 58 held in an insert groove 60. The insert 58 is preferably a hard insert, and more preferably a hard metal insert, and most preferably a stainless steel insert. The insert 58 may be polished to reduce sliding friction.

(19) A perspective view of three consecutive end caps 46 and slats 20 is shown in FIG. 4 and a perspective view of the end cap 46, the slat 20, and a flexible joiner member 38 is shown in FIG. 5. One of the end caps 46 is attached to each slat 20 by a fastener 48. The fastener 48 is preferably a screw engaging the “C” shaped center middle wall 36 (see FIG. 6) of each slat 20, and more preferably a stainless steel screw, for example, 304 stainless steel. Each joiner member 38 engages consecutive slats 20 to connect the slats.

(20) A cross-sectional view of the slat 20 is shown in FIG. 6. The slat 20 includes a front side 20a, a rear side 20b, end walls 30 and the middle wall 36 reaching between a top surface 32 and bottom surface 34. The middle wall 36 includes a center “C” shaped portion 36c and vertical portion 36a reaching up from the center “C” shaped portion 36b to the slat top surface 32 and vertical portion 36c down from the center “C” shaped portion 36b to the slat bottom 34. The center “C” shaped portion 36b includes a rearward facing opening 37 having top and bottom lips 37a and 37b partially closing the opening 37. Chambers 26 are defined between the middle wall 36 and the end walls 30 and connector channels 28 are defined outside the end walls 30. A rearward end 24 is at the right end of the top surface and an overlapping forward end 22 is at the opposite left end of the top surface 32. The “C” shaped center portion of the middle wall improves and economizes the manufacturing process, and facilitates tight attachment of the cap ends 30 to the slats 20.

(21) A cross-sectional view of the flexible joiner member 38 is shown in FIG. 7 and a cross-sectional view of consecutive slats 20 connected by the flexible joiner member 38 is shown in FIG. 8. The flexible joiner member 38 includes a center 42 and two connector ports 40. The connector portions 40 engage the connector channels 28 of consecutive slats 20 to connect the slats 20. The center 42 allows the slats 20 to move sufficiently to coil within the holder 14 (see FIG. 12).

(22) A perspective inner and top view of the end cap 30 is shown in FIG. 9, an outer end view of the end cap 30 is shown in FIG. 10 and a bottom view of the slats 20 and the end caps 30 is shown in FIG. 11. The end cap 30 includes inserts 52 which enter the chambers 26 (see FIG. 6) of the slats 20, the inserts 52 including tapers 50 to facilitate engaging the chambers 26. Sliding surfaces 54 slide on the inserts 58 in the rails 18. The end caps 46 are preferably plastic, and more preferably Polyoxymethylene and the sliding surfaces 54 are preferably polished to reduce friction. The fastener 44 passes through a passage 56 to attach the end caps 30 to the slats 20.

(23) A cross-sectional view of the holder 14 and cover 12 is shown in FIG. 12. The holder 14 includes spiral guides 62 to guide the cover 12 into the holder. A rear most slat 20 of the cover 12 includes a lip to prevent the cover entering too far onto the holder and to extract the cover 12 from the holder 14.

(24) While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
