Tonneau cover

Abstract

A tonneau cover assembly is provided having a plurality of substantially rigid panels inserted between the fabric and the bows and then locked into place and/or supported by snap-fit elements connecting to the peripheral frame of the tonneau cover. The snap-fit elements can also serve to positively locate the bows with respect to the frame. The panels can be closely dimensioned with respect to the distance across the frame or spaced somewhat to accommodate insertion about frame hinges and/or close fitting fabric, bows and frames. Two sided adhesive tape can be used between the panels and the snap-fit elements and the bows to maintain panel placement in the event that the assembly is to be a permanent aspect of the tonneau cover. Panels can also be perforated for weight reduction and/or cost savings without significant loss of theft security. Panels can be padded for impact absorption without permanent deformation so as to maintain tonneau cover attractiveness despite significant wear and tear during use.

Description

BACKGROUND AND SUMMARY OF THE INVENTION[0001]The present invention relates generally to fabric and frame enclosures and, more particularly, to tonneau covers for pick-up trucks. This invention is an improvement upon the invention disclosed in U.S. patent application Ser. No. 10 / 286,711, filed on Nov. 4, 2002, the specification of which is incorporated by reference herein. The invention of that prior patent application was embodied in the Torza Top tonneau cover product made and sold by Advantage Company of Elkhart, Ind.[0002]In general, prior tonneau covers have been of two types: hard and soft. Soft covers have been essentially formed from a fabric cover mounted over a metal frame. The frame typically extends about the periphery of the pick-up truck bed. The fabric can be vinyl or cloth or other flexible material, usually one that is waterproof or water resistant. The fabric can be a single cut piece or multiple pieces sewn together. Multiple pieces can be less costly to produce th...

Benefits of technology

[0005]Hard cover and soft cover tonneau covers also differ in other features. Hard covers tend to be more waterproof and resistant of theft of pick-up truck bed contents. Hard covers tend to withstand greater loads from snow or items/persons placed on top of the tonneau cover. Hard covers are less prone to tearing and puncture damage in general than many soft covers. Hard covers are less prone to deformation at higher speeds of travel and, thus may provide some benefits to vehicle fuel efficiency in that regard as well as to overall product durability and longevity. On the other hand, hard covers do not typically have a “soft” look and feel, such as that resembling a convertible top automobile. Moreover, the lighter weight of soft covers can benefit overall vehicle fuel economy more in that way. Given the tremendous variety in hard and soft covers, it is hard to say that one or the other will normally be less expensive, but in general the price range of soft covers goes lower than hard covers. Accordingly, tonneau cover users may start out with a soft cover, but over time may desire to upgrade to a hard cover.

[0006]Accordingly, it is an object of the present invention to provide improved tonneau cover assemblies. More particularly, objectives of the present invention include providing soft cover tonneaus with many of the advantages of hard covers, but without some of the drawbacks of hard covers. For example, those objectives would include greater durability and theft protection, greater water resistance, better fuel economy from shape maintenance, and larger load endurance while keeping costs and overall weight low and maintaining a soft look and feel and

Problems solved by technology

Multiple pieces can be less costly to produce that a single cut piece, but have occasionally had the disadvantage of seam leakage.

Coatings or special assembly can be used to reduce seam leakage, but that can add to production costs and may wear off in time.

Such extrusions are lighter in weight and not prone to rust as compared to angle iron, but may be more costly to produce.
