FIELD OF THE INVENTION
The present invention relates to folding truck bed covers with self-locking compound hinges.
BACKGROUND INFORMATION
Various types of truck bed covers, also known as tonneau covers, are known. A need exists for covers that are easy to install and use, and are secure against unwanted opening or break-ins.
SUMMARY OF THE INVENTION
The present invention provides folding truck bed covers with self-locking compound hinges. The covers may include rigid front, middle and rear panels. To open the cover, the rear panel is folded over the middle panel, then the folded middle and rear panels are folded over the front panel. A front edge of the middle panel may be pivotally mounted to a rear edge of the front panel by a compound hinge assembly including at least one compound or double hinge that permits the folded rear and middle panels to fold onto the top outer surface of the front panel. The compound hinge assembly may be used with a catch bar and catch bracket that provide a self-locking feature that prevents unwanted opening or break-ins of the cover when the cover is in its fully closed position.
An aspect of the present invention is to provide a multiple-panel folding truck bed cover comprising a front panel structured and arranged for mounting on truck sidewall rails comprising a front panel rear edge, a middle panel structured and arranged for mounting on the truck sidewall rails comprising a middle panel front edge, at least one compound hinge attached to the front panel adjacent the front panel rear edge and attached to the middle panel adjacent the middle panel front edge, and a catch bar and catch bracket assembly structured and arranged to resist relative movement between the front panel rear edge and the middle panel front edge when the front panel and the middle panel are in closed positions on the truck sidewall rails. The catch bar and catch bracket assembly comprises a catch bar attached adjacent to one of the front panel rear edge or the middle panel front edge, and at least one catch bracket attached adjacent to the other one of the front panel rear edge or the middle panel front edge structured and arranged to engage the catch bar to thereby resist the relative movement between the front panel rear edge and the middle panel front edge when the front panel and the middle panel are in the closed positions.
Another aspect of the present invention is to provide a multiple-panel folding truck bed cover comprising a front panel structured and arranged for mounting on truck sidewall rails comprising a front panel rear edge, a middle panel structured and arranged for mounting on the truck sidewall rails comprising a middle panel front edge, and at least two compound hinges attached to the front panel adjacent the front panel rear edge and attached to the middle panel adjacent the middle panel front edge spaced apart from each other transversely along a seam between the front panel rear edge and the middle panel front edge.

DETAILED DESCRIPTION
The present invention provides folding truck bed covers with self-locking compound hinges. The covers may include rigid front, middle and rear or tail panels. The front, middle and rear panels may be load-bearing panels capable of holding significant amounts of weight, e.g., for hauling various types of equipment and/or tools thereon. To open the cover, the rear panel is folded over the middle panel, then the folded middle and rear panels are folded over the front panel. A front edge of the middle panel may be pivotally mounted to a rear edge of the front panel by a compound hinge assembly. The compound hinge assembly includes at least one compound or double hinge that permits the folded rear and middle panels to fold onto the top outer surface of the front panel, with the bottom inner surface of the rear panel resting on the top outer surface of the front panel. In one embodiment, the compound hinge assembly includes two separate compound hinges spaced from each other transversely along a seam extending between the front edge of the middle panel and a rear edge of the front panel. A front edge of the rear panel may be pivotally mounted to a rear edge of the middle panel, for example, by at least one hinge. The rear panel may be pivoted from a flat closed position 180 degrees to an open position in which the top outer surface of the rigid rear panel contacts and rests on the top outer surface of the rigid middle panel. In the fully folded or open position, the top outer surfaces of the rigid middle and rear panels continue to contact each other, and the bottom inner surface of the rigid middle panel faces upward. The compound hinge assembly connecting the front and middle panels allows sufficient clearance space for the rear panel to be folded between the front panel and the middle panel when the cover is in its open position.
The multiple-panel folding truck bed cover also includes a self-locking feature that, in combination with the compound hinge assembly, prevents unwanted opening or break-ins of the cover when the cover is in its fully closed position. Self-locking may be achieved by the use of a catch bar and catch brackets that engage with each other when the middle panel is in its closed position nexted to the front panel.
FIGS. 1-7 illustrate a multiple-panel folding truck bed cover 10 of the present invention attached to a truck bed 5 with sidewall rails 6. The multiple-panel folding truck bed cover 10 includes a rear panel 12, middle panel 13, and front panel 14. The rear, middle and front panels 12, 13, 14 may be rigid and load-bearing, for example, capable of holding at least 100 lbs, or at least 200 lbs, or at least 400 lbs or more. The rear panel 12 and middle panel 13 are pivotally connected together by rear hinges 28, and the middle panel 13 and front panel 14 are pivotally connected together by compound hinges 38. The multiple-panel folding truck bed cover 10 may be secured to the truck sidewall rails 6, for example, with clamps provided on the underside of the front panel 14 and clamps provided on the underside of the rear panel 12. FIGS. 4 and 6 show rear panel clamps 18 provided on opposite sides of the rear panel 12 to provide two securement locations for the rear panel 12 when in its closed position. The rear panel clamps 18 may be accessed when the tailgate is opened, but are not accessible when the tailgate is closed and locked. In addition, front panel clamps 16, such as the one shown in FIG. 16, may be provided on opposite sides of the front panel 14. As shown in FIG. 3, straps may be used to hold down and secure the middle panel 13 and underlying rear panel 12 in the open position. The tie-down straps may be secured to anchor plates or tie down clamps on the front panel 14, such as the front tie down clips 49 described below.
As shown in FIGS. 4-6, the rear panel 12 includes a top surface 20, bottom surface 21, right side edge 23, left side edge 24, rear edge 25, and front edge 26. As shown in FIGS. 4 and 6, a support stud 22 is secured to the bottom surface 21 of the rear panel 12.
As shown in FIGS. 5 and 6, the middle panel 13 includes a top surface 30, bottom surface 31, right side edge 33, left side edge 34, rear edge 35, and front edge 36. As shown in FIG. 6, support studs 32 are attached to the bottom surface 31 of the middle panel 13.
As shown in FIGS. 5 and 6, the front panel 14 includes a top surface 40, bottom surface 41, right side edge 43, left side edge 44, rear edge 45, and front edge 48. Support studs 42 are attached to the bottom surface 41 of the front panel 14. Front tie down clips 49 may be provided on the front edge 48 for receiving the hold-down straps noted above.
FIGS. 7 and 10-14 illustrate details of the compound hinges 38. The compound hinge 38 includes a rear bracket 51, front bracket 52, and spacer bracket 53. The rear bracket 51 is attached to the spacer bracket 53 by a rear pivot pin 55. The front bracket 52 is attached to the spacer bracket 53 by a front pivot pin 56. Mechanical fasteners 54 such as bolts, rivets or the like are used to fasten the rear bracket 51 to the middle panel 13. The catch bar 46 includes a catch lip 47. The catch lip 47 of the catch bar 46 forms a water-diverting trough or channel when the middle panel 13 is in its closed position.
FIG. 10 is a side perspective view of a compound hinge attached at one end to a top surface of a front panel and attached at an opposite end to a top surface of a middle panel of a truck bed cover. FIG. 11 is a side perspective view of the compound hinge of FIG. 10 illustrating the ability of the compound hinge to allow relative sliding movement between the middle panel and front panel during folding of the panels. The compound hinges 38 thus provide tolerance or play between the relative positions of the front 14, middle 13, and rear 12 panels when the panels are folded.
FIGS. 10-16 illustrate a catch bar 46 secured adjacent the rear edge 65 of the front panel 14. The catch bar 46 may be attached at the rear edge 45 of the front panel 14, and may be located below the seam between the front 14 and middle 13 panels when the middle panel 13 is in its closed position. The catch bar 46 may also serve as a rain gutter or water-diverting channel. Drain holes may be provided in the front edge 36 of the middle panel 13. When the middle panel 13 is in its closed position, the drain holes extending through the sheet material of the front edge 36 may be located above the rain gutter or channel provided as part of the catch bar 46 and catch lip 47 located below the rear edge 45 of the front panel 14 to thereby allow water and other liquids to drain through the holes into the rain gutter or channel. Any suitable number of drain holes may be provided, for example, one to six or more drain holes across the transverse width of the front edge 36 of the middle panel 13.
FIGS. 6 and 12-16 illustrate a catch bracket 60. The catch bracket 60 may include a base 61, arm 62 and latch tab 63. The latch tabs 63 of the catch bracket 60 rotate into latching positions underneath the securing catch bar 46 when the middle panel 13 is rotated from its open position to its closed position. Opposing gasket seals 64 may be used to seal the seam between the rear edge 45 of the front panel 14 and the front edge 36 of the middle panel 13.
In the embodiment shown in FIG. 12, the base 61 comprises a flat plate attached to the bottom surface 31 of the middle panel 13 with the fasteners 54 and attachment nuts and washers 58. In the embodiment shown in FIG. 13, the catch base 61A is channeled with a generally U-shaped cross section that receives interior attachment nuts and washers 59 therein. The ends of the U-shaped arms of the channeled base 61A contact the bottom surface 31 of the middle panel 13. The fasteners 54 extend through the rear bracket 51 and middle panel 13 and are secured by the interior attachment nuts and washers 59, which are located in the channeled base 61A when assembled. The exposed attachment nuts and washers 58 are then used to secure the bracket 61A onto the middle panel 13.
FIG. 8 illustrates the front panel 14 of a multiple-panel folding truck bed cover including front tie downs 49 attached adjacent the front edge 48 of the panel, and side tie downs 49A attached to the side edges 43 and 44 of the front panel 14. FIG. 9 illustrates side tie downs 29A and 29B attached to the rear panel 12 and front panel 14 of a multiple-panel folding truck bed cover.
As shown in FIG. 6, underside tie down clips 39 may be attached to the support stud(s) 32 of the middle panel 13, or may be attached at any desired locations on the undersides of the panels 12, 13 and 14. For example, tie-down clips, clamps or brackets may be fastened to hinges connecting the rear and middle panels. Such tie-down clamps may thus be integrated with the hinges. Although not shown, additional tie-down clamps may be secured to the compound hinges between the middle and front panels.
FIG. 17 illustrates a top side perspective view illustrating the use of a pry bar P to lift a middle panel in relation to a front panel when compound hinges are used without a catch bar and catch bracket. The pry bar P is being used in an attempt to break into the truck bed cover 10 without latch tabs of the present invention. FIG. 18 illustrates a top side perspective view illustrating a pry bar that is unable to significantly open the middle panel in relation to the front panel when a catch bar and catch bracket are provided in combination with the compound hinges. When equipped with the catch bar and catch brackets of the present invention, the middle panel 13 is substantially prevented from being opened at the front edge 36 of the panel adjacent the compound hinges 38. The catch bar 46 and catch brackets 60 thus provide anti-break-in security features in comparison with truck bed covers that do not include such a combination of a catch bar and brackets, and in comparison with conventional truck bed covers that may be more susceptible to damage and break-ins.
