A retractable trailer cover adapted for mounting to an existing boat trailer and a method for retrofitting the trailer cover to the boat trailer. The trailer cover includes multiple ribs extending from one side to the other, a flexible cover material, two elongated tracks, and multiple wheels received within the tracks. The ribs are affixed to the wheels so as to be slidably mounted to the tracks. Mounting brackets can be spaced along each of the trailer cover sides, and the tracks can be affixed to the mounting brackets. To mount the trailer cover to the boat trailer, the mounting brackets can be attached to a frame of the boat trailer. The trailer cover can selectively be expanded and retracted to cover and uncover an associated boat and boat trailer and may be used with new or used trailers.

A tonneau system for use with a pickup truck. The tonneau system includes a frame and a tonneau cover having a plurality of tonneau sections moveable between a folded position and an unfolded position. The tonneau cover includes solar energy-receiving material secured to a top exposed surface of at least two of the tonneau sections. The solar energy-receiving material moves with their corresponding tonneau sections between the unfolded and folded positions. A battery, transformer, and/or electrical cabling system may be included within the circuit for power storage and conversion.

This invention is relevant to a steady bed cover of pickup truck. The bed cover includes at least two plates. The adjacent plates are connected by rotating shaft structure. This invention provides a steady bed cover of pickup truck with simple structure and great leading function. The connecting strength of rotating shaft structure is enhanced with the cooperation of the ladder-like hook and strip convex. When the bed cover of pickup truck is laid horizontally, the rotating part and the rotating shaft part are subjected to reverse force and are mutually matched, thus enhancing the stability of the bed cover.

The application discloses a fixing and mounting structure for a vehicle cover which includes a vehicle cover and two mounting rods. The two mounting rods are parallel to each other. The vehicle cover is laid on the two parallel mounting rods. The fixing and mounting structure further includes a front railing, a fixed bolt, a first slider, a second slider and a locking nut. The front railing is fixed on the vehicle cover. The first slider is slidably arranged on the front railing. The fixed bolt is arranged on the first slider. The locking nut is matched with the fixed bolt. A sliding hole is defined in the second slider, and the fixed bolt passes through the sliding hole in the second slider. The locking nut abuts against the second slider, and the second slider cooperates with the front railing to clamp the mounting rods. The disclosure has following advantageous effects that: a fastening between the vehicle cover and the mounting rods is realized by actions of the first slider, the second slider, the fixed bolt and the locking nut, so that a fastening strength and position between the vehicle cover and the mounting rod is adjustable.

A tonneau cover and a method of attachment are disclosed herein. In some embodiments, a self-energizing clamp can be used to retain a tonneau cover onto a side wall of a truck bed, or other vehicle bed. In some embodiments, the clamp can be rotated between a usage position and a storage position in order to prevent the clamp from incidental movement or harm while accessing the truck bed.
