A retractable truck bed closure is disclosed herein. The retractable truck bed closure comprises a pair of frames that extend across a truck bed between sidewalls of the truck bed. The closure may be moved between a stored configuration and an extended configuration along the pair of frames to open, and close, a portion of the truck bed, respectively. The frames may be attachable to the truck, or may be integrated into portions of the truck, such as the sidewalls of the truck bed or the rear of the cab of the truck.

A device for covering a surface including a substantially rectangular cover (10) having first and second longitudinal edges each provided with a protruding convex bead (12) having a minimum diameter (d), two rails (6) including a groove, the opening (14) of which has a maximum width (Lo), a drum (2) that is able to move above the surface in order to deploy or retrieve the cover, an insertion system (16) for continuous insertion of the convex bead (12) into the groove. The convex bead (12) of each longitudinal edge and the groove of the corresponding rail are configured such that, once inserted into the space (14e) by the insertion system, the convex bead occupying the space alone cannot be removed solely by the action of a force (F) applied parallel to the transverse axis (Y) in the direction of the surface to be covered.

A tonneau cover comprising: (a) a slat; (b) a drive system adapted to move the slat; and (c) a disconnect connected to the slat and in communication with the drive system, wherein the disconnect is adapted to release from communication with the drive system so that the slat manually moves independently from the drive system.

A tonneau cover configured to cover a cargo box of a vehicle, comprising: (a) opposing side rails configured to attach to opposing sides of the cargo box; (b) a slat extending between and supported by the opposing siderails, wherein the slat is configured to move along the siderails; and (c) a drive system that drives the slat and moves the slat along the side rails from a closed position where the slat covers an interior of the cargo box, to an open position where the interior of the cargo box is exposed, wherein the drive system is controlled wirelessly by a remote device, by a sensor located along the cargo box, or both.

A side rail for a cargo bed of a vehicle enables the fitting or mounting of a broad range of automotive accessories to a roll top cover. The side rail comprises: an elongate body that defines a longitudinal axis; an axially extending drive channel disposed at a medial side of the body and defining an opening therein for receiving a drive chain, the drive channel having a recessed inner portion and a stepped outer portion adjacent the opening; an axially extending first support channel recessed in an upper side of the body and opening upwardly therefrom; and an axially extending second support channel recessed in the upper side of the body and opening upwardly therefrom, the second support channel disposed laterally adjacent to the first support channel.

A dual action truck cover provides two modes, actions or ways to access contents in a truck bed. Side rails can be mountable to a cargo box so as to be pivotable between a raised position to provide a rear opening in an open pivot arrangement, and a lowered or closed pivot arrangement. The side rails can be spaced apart to define an inter-rail area therebetween. A door can include a plurality of elements hingedly coupled together and extending between the side rails and movable between a closed door arrangement wherein the elements cover the inter-rail area, and an open door arrangement in which the elements are positioned to permit access through the inter-rail area. The door can move between the open and closed arrangements by rolling up the hingedly coupled elements together or folding the elements together.

A tonneau system that includes a tonneau cover and a canister. The canister includes one or more tracks for guiding the tonneau cover within the canister during movement of the tonneau cover relative to the canister; and a retraction system including: a drive roller; one or more drive gears; and a bias member that moves the drive roller and the one or more gears to assist in moving the tonneau cover relative to the canister.

A retractable cover system includes a pre-assembled drive system including a main roller about which a flexible cover is wrapped. Bows support the flexible cover in an extended position. The bows include a last bow. A drive motor is operatively coupled to the main roller and is configured to move the flexible cover between the extended position and a retracted position. A pre-assembled guide rail includes a cable system that has a driven gear operatively coupled to a drum. A cable is wrapped about the drum and at least one idler. The last bow is unsecured to the cable of the pre-assembled guide rail. A joint is configured to interconnect the pre-assembled guide rail to the pre-assembled drive system in an assembled condition to provide an assembled retractable cover system. The joint permits the drive gear and the driven gear to engage one another in the assembled condition. The last bow is secured to the cable in the assembled condition.

A locking device for a covering member to provide sealing in storage, cargo, and other personal applications is disclosed. The locking device comprises a pipe member having predetermined length is configured to have a transverse opening. The covering member is slidably attached to a bead insert positioned inside the pipe member via the transverse opening, wherein the covering member is configured to securely wrap the contents of a storage space. The locking device is configured to enable a climate controlled environment for the wrapped contents of the storage space. A locking assembly and method of using the same is also disclosed.

A roll-up cover assembly includes a cover assembly comprising first and second side rails and front and rear bumpers, as well as a cover, wherein a lower portion of an inner side of the first side rail is provided with a slideway, an adjustment base, an adjustment screw, an adjustment knob, a receiver; the adjustment base is fixed inside the first side rail and can not be moved; the adjustment base is provided with the adjustment knob thereon, the adjustment screw passes through the adjustment base and the adjustment knob, and an end part of the adjustment screw is snap-fixed into a groove on the receiver; the receiver is a separated-type structure, wherein both of the upper and lower portions are fixed onto the slideway, and when the adjustment knob is turned, the adjustment screw produces a displacement and drives the receiver to slide within the slideway.
