FIELD

The present teachings relate to hook and loop fasteners, and specifically, the hook and loop fasteners relate to a fastening means for vehicle bed covers.

BACKGROUND

Flexible vehicle bed covers generally are rolled across the vehicle bed and engaged by hoop and loop fasteners for quick and efficient covering of the contents of the vehicle bed. Many flexible covers that use hook and loop fasteners tend to engage before the user has had a chance to evenly distribute the cover over the vehicle bed. When the flexible cover is unevenly distributed on the vehicle bed, it is difficult to protect the contents of the vehicle from inclement weather and theft, and untightened portions of the cover may collect fluid, which may eventually ingress into the vehicle bed. Furthermore, every readjustment of the flexible cover causes the hook and loop fasteners to degrade faster, which then requires replacement.

Examples of some hook and loop fasteners can be found in U.S. Pat. Nos. 8,523,266; 8,167,353; 7,815,239; and 6,544,245 and YouTube videos TruXedo Titanium Hard Rolling Tonneau Features and Benefits, published on Jul. 17, 2015 and TruXedo TruXport Roll-Up Truck Bed Cover Features and Benefits, published on Jun. 6, 2017 all of which are incorporated by reference herein for all purposes. What is needed is a flexible cover that will not pre-engage when the user rolls the flexible cover over the vehicle bed. What is needed is a flexible cover that will rest on sides of the vehicle bed before the user is ready to engage the flexible cover. What is needed is a flexible cover that requires an extra step or user engagement to engage the flexible cover.

The row of fasteners may have a ratio of dual hooks to opposing dual hooks of 1:1 or more, 1:2 or more, 1:3 or more, or 1:4 or more. Preferably, the ratio of dual hooks to opposing dual hooks is 1:1. The row of fasteners may form a pattern of dual hooks such that the dual hooks, opposing dual hooks, and spacers alternate.

The dual hooks may function to engage with the strip of loop fasteners. The dual hooks may have a vertical length of about 0.025 mm to about 2.54 mm. Preferably, the dual hooks may have a vertical length of about 0.300 mm to about 0.800 mm. The dual hooks may be supported in a vertical position by the one or more support structures. The dual hooks may include a top edge, a front hook, a rear hook, a connection edge, a trench, or a combination thereof. The front hook of the dual hooks and the front hook of the opposing dual hooks may face opposite directions. The dual hooks may alternate with the opposing dual hooks in the row of the fasteners. For example, a dual hook may precede an opposing dual hook, another hook may follow the opposing dual hook, and another opposing dual hook may follow the another dual hook so that the dual hooks and the opposing dual hooks form a pattern in the row of fasteners. The dual hooks may alternate with the spacers in the row of fasteners. The front hook, the rear hook, or both of the dual hooks may engage with the strip of loop fasteners. The front hook and the rear hook of each the dual hooks may face the same direction. For example, a hook may have a front hook and a rear hook and the front hook and the rear hook may extend in a same direction. The top surface of the dual hooks may be lowered below the upper surface of the spacers by distance. The distance may be 0.1 μm or more, 0.2 μm or more, 0.3 μm or more, 0.4 μm or more, or 0.5 μm or more.

The trench may be a vertical distance below the top edge of the dual hooks, the upper surface of the spacers, or both. The trench may be located between the connection lip of the rear hook and the rounded edge of the front hook.

The connection lip or tip may function to connect the strip of fasteners and the front hook, the rear hook, or both. The connection lip may substantially curve into a point. The connection lip may slope down into the connection edge of the dual hook, opposing dual hook, or both. The connection lip and the strip of loop fasteners may connect such that the flexible cover is secure and engaged on the side rails and encased over the vehicle bed. The connection lip may be sufficiently below the upper surface of the spacer such that a force is needed to engage the connection lip and the loop fastener. The connection lip and loop fastener may engage when a force is applied to the flexible cover such that the loop fasteners are pushed down past the elevated upper surface of the plurality of spacers and the top edge of the dual hooks. The connection lip may curve into a point, a rounded edge, a hooked edge, a crescent edge, or a combination thereof. The connection lip may slant downward (e.g., be angled down towards the bed of the vehicle) toward the base or may slant upward and away from the base of the side rail fasteners.

The distance from one side edge to an opposing side edge may define a total width of the spacer. For the dual hooks, opposing dual hooks, or both, the distance from the connection lip of the front hook to the angled wall of the rear hook may define a total width of the dual hooks. The total width of the spacers and the total width of the dual hooks may be substantially the same. The total width of the spacer may be less than the total width of the dual hooks such that the front hook of the dual hook protrudes past the side edge of the spacers. The total width of the spacer may be more than the total width of the dual hooks such that the spacers prevent pre-engagement of the dual hooks and the strip of loop fasteners.

The bottom edge may function to connect the spacer to the base of the side rail fasteners. The bottom edge may be level with the lowest point of the support structure. The bottom edge may be level with the connection edge of the dual hooks, opposing dual hooks, or both. The bottom edge may define a mold between the spacer and the base.
