The present invention discloses a truck box cover device extended and retracted in a transmission manner. The truck box cover device extended and retracted in a transmission manner comprises a clutch type driving gearbox, a roller shutter shaft and roller shutter cover rail support frames. The clutch type driving gearbox is connected with the roller shutter shaft. The roller shutter shaft is stripped winding shaft and comprises a transmission end and a roller shutter cover mounting shaft. One end of the transmission end is connected with the clutch type driving gearbox and is driven by the clutch type driving gearbox to correspondingly rotate, and the other end is connected to the roller shutter cover mounting shaft. One end, away from the transmission end, of the roller shutter cover mounting shaft is fixed to the interior of a driven bearing.

A tonneau system comprising: (a) a plurality of tonneau sections; (b) a retraction system including: (i) a drive roller; (ii) a pulley spaced apart from the drive roller; (iii) a track extending from a location proximate to the drive roller to a location proximate to the pulley; and (iv) a line connected to the drive roller and one or more of the plurality of tonneau sections; wherein the line extends between the one or more of the plurality of tonneau sections and the driver roller when the plurality of tonneau sections are in the closed position, and the line extends from the one or more of the plurality of tonneau sections around the pulley and to the drive roller when the plurality of tonneau sections are in the stored position.

There is provided herein improvements in deployable canopies for utility vehicles having a cabin and a cargo bay. According to one aspect, the system comprises a deployable canopy which has a roof portion and rearward columns extending downwardly therefrom. The roof portion slides along cabin roof tracks and the columns slide along cargo bay edge tracks longitudinally from stowed to deployed positions for selectively enclosing the canopy bay. The deployable canopy may stow side panels horizontally therein, which when the canopy is deployed, the side panels slide therefrom transitioning from horizontally to vertically, typically under automatic mechanical actuator control, using an arrangement of tracks. According to another aspect, the system has a removable cassette that selectively engages longitudinally between forward and rearward builder bars and have longitudinal lateral openings from which side covers unfurl slide within builder bars tracks.

A canister comprising: (a) a space configured to receive a tonneau cover so that the tonneau cover is stored within the canister; and (b) one or more track guides that guide the canister relative to a roller track, a bed of a vehicle, a rail extension, a cap, or a combination thereof; and wherein the one or more track guides assist the canister in being inserted into or removed from the bed of the vehicle.

A retractable cover system includes laterally spaced apart guide rails that each provide a track. A drive assembly includes a motor operatively connected to a gear. A cover has multiple slats configured to interlock with one another in a deployed configuration. The slats cooperate with the gear and are slidable in the tracks between first and second positions within the opening in response to actuation of the drive system. The slats are stacked onto one another in a stowed configuration. A method of servicing a retractable cover system includes the step of removing an access cover from a magazine to expose a cavity housing stacked rigid slats. A method of retracting a tonneau cover includes the steps of actuating a handle and decoupling the tonneau cover from a drive mechanism.

An end cap for a roller tonneau cover of a truck includes, among other things, an end portion having a primary sliding surface and a first interlocking feature that provides an interface between the end cap and a slat of the tonneau cover, a tooth portion including teeth for engaging with a pinion gear, and a connection portion between the end portion and the tooth portion.

A bed cover assembly for a pickup truck may include cover guides coupled to upper ends of both body sides of a pickup truck and having guide means such as a guide rail formed inward of the truck; a bed cover coupled between the cover guides to slide along the guide means; and rotary guide rail assemblies hinged to both body sides of the rear of the truck, wherein when the bed cover moves rearward, the rotary guide rail assemblies rotate upward about respective hinge axes thereof and the bed cover moves along guide means formed at the rotary guide rail assemblies.

Disclosed are embodiments of a retractable tonneau cover for a vehicle that has been modified in order to generally minimize the size of a housing of the tonneau cover, providing more vehicle cargo space for a user. The modified retractable tonneau cover can be automatically closed through an electronic system.

A canister comprising: (a) a space configured to receive a tonneau cover so that the tonneau cover is stored within the canister; and (b) one or more track guides that guide the canister relative to a roller track, a bed of a vehicle, a rail extension, a cap, or a combination thereof; and wherein the one or more track guides assist the canister in being inserted into or removed from the bed of the vehicle.

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.
