A cover assembly for a truck bed of a pick-up type vehicle has a cover assembly including a rollable curtain with transverse adjacent panels hingedly linked to one another, side rails mounted on upper portions of side walls of the truck bed for guiding end portions of the transverse adjacent panels, and a housing that receives and stores the rollable curtain. The side rails are mounted on upper portions of side walls of the truck bed for guiding end portions of the transverse adjacent panels. The housing has a transverse rotatable shaft configured to undergo rotational movement, at least one sleeve element mounted on the transverse rotatable shaft, an engagement element mounted to the at least one sleeve element and configured to engage an inner end of the rollable curtain, and inwardly extending continuous helical trackways defining a rolling path formed on respective sidewalls of the housing.

A cover assembly for the truck bed of a pick-up type vehicle, said assembly comprising a motorised rollable curtain (1) formed by a plurality of adjacent transverse panels (2), which are continuously connected along their transverse length by hinge joints (3), and an end slat (4), said curtain (1) coupled at one end to a transverse rotatable shaft to allow winding and unwinding thereon, wherein the end slat (4) comprises one or more electric elements (16, 17, 18, 19) connected to a stationary electric element, i.e., a smart-AI control circuit board (9) mounted on the housing box (7), in such a manner that the electric elements (16, 17, 18, 19) are continuously powered during operation of the cover assembly.

A roller shutter cover, including a slide rail, a roller shutter, and a manual driving structure, where the roller shutter is connected to the slide rail and can move on the slide rail, the roller shutter includes a plurality of sequentially connected shutter slats, and the manual driving structure is disposed at one end of the roller shutter and can drive the roller shutter to move on the slide rail so that the roller shutter switches between an opened state and a storage state. As the roller shutter cover is provided with the slide rail, the slide rail can enable the roller shutter to move more smoothly and can also cover an edge of the roller shutter to prevent rainwater and the like from entering a truck bed. Meanwhile, the manual driving structure can drive the roller shutter to move, thereby saving time and labor.

The present invention relates to a self-propelled earth working machine (10) for removing material and/or changing a density of ground material and/or changing a ground surface (AO) and/or applying material onto a ground area (U), the earth working machine (10) comprising: a machine frame (12), a traveling gear (22) supporting the machine frame (12), a working apparatus (32) for earth working, a power source (39) for supplying power to at least one functional module, comprising the working apparatus (32) and a travel drive, the earth working machine (10) comprising an operator's platform (24) having a canopy (44) having a variable canopy area (54).
The invention provides for the canopy area (54) to be variable in the longitudinal machine direction (L).

The present invention discloses an aluminum roll cover and a pickup truck equipped with the aluminum roll cover. It comprises a front cover, an intermediate profile rubber strip assembly, a tailgate, a latch bolt system, a clip system, a guide rail system and a storage box. By providing the storage box, the present invention facilitates the rolling up and storage of the roll cover. Moreover, a spring is arranged inside the storage box, and the elastic force of the spring is utilized for rolling up, which saves time and effort and is convenient to operate.

A multipurpose truck bed cover device is provided. The device is comprised of a truck bed cover designed to enhance the versatility of truck beds by offering three primary configurations: a bed cap mode for enclosed storage, a tonneau cover mode for low-profile coverage, and an open bed mode to restore the truck bed to its standard open layout. The device comprises a rectangular body with at least three side walls mounted on sliding tracks, a top wall that may fold, roll, or telescope, and locking mechanisms to secure configurations during operation. In motorized versions, electric motors powered by the truck's electrical system enable the raising and lowering of the body between modes as well as control of the top wall.

A vehicle system includes a plurality of fins engaged with a bed wall of a cargo bed. The plurality of fins are configured to move telescopically back-and-forth between a stowed position and a deployed position. The fins can be disposed along a vertical top of the bed wall. The fins can slidably engage the bed wall.
