The invention relates to a belt tensioning carriage device for moving an awning, used to make the teethed movement belts of an awning installed in a pergola tense, in which the awning slides almost horizontally along lateral guides, such that the belt and the tensioning carriage device slide. The invention also relates to a movement system of an awning along the guides of a pergola.

Provided is an awning system comprising: a) two vertical tracks; b) two arms, with each arm attached at a first end to one of the vertical tracks, the arm configured to move in :a vertical direction and pivot in relation to the track, each arm further configured to be extendible; c) a cross-bar, with each end of the cross-bar attached to a second end of one of the arms; d) a piece of fabric attached at one end to the cross-bar; and e) a holder placed on top of the tracks for holding a second end of the fabric; wherein the awning fabric is configured to be adjusted in both the vertical and the horizontal direction; wherein a user can move the arms vertically and extend the arms to adjust a position of the fabric. Provided is a retractable canopy system comprising: a) a track; b) a frame movably attached to the track; c) a support attached to the frame; d) a connector movably attached to the support, e) two or more rods attached to the connector; f) a canopy piece attached to the rods; wherein the awning is configured to have a stowed and deployed position that are obtained by moving the frame against the track.

A motorized shade assembly is provided having a discontinuous web extending between two rollers, one of which is motorized and the other is tensioned or biased toward rotation away from the other roller. The roller motor can be mounted inside of one of the rollers, and the tensioning device, such as a torsion spring, can be mounted inside of the other roller. The web includes a shade portion and a strap portion, with a rigid draw bar at the junction of those portions. Rotation of the rollers causes the strap portion to wrap over one of the rollers as the shade portion unwraps from the other roller. The shade assembly can be positioned between an inclined or curved vehicle window and an interior shroud for the window, such as found with a cab-over window of a Class B motorhome. The draw bar and fasteners connecting the strap to the draw bar facilitate movement of the shade when in contact with the shroud. Friction reducing tape or surface treatment on the periphery of the window opening in the shroud can also facilitate movement of the shade when in contact with the shroud. Motor actuation can be hardwired to a desired location within the vehicle, or wirelessly controlled by the user, as with an RF device.

An awning assembly and method of construction that includes a first main member rotatably coupled to a vertical track at a first end of the first main member; a second main member pivotally coupled to and at a second end of the first main member; a first supplemental member rotatably and slidably connected to the vertical track at a first end of the first supplemental member; a second supplemental member having a first end pivotally coupled to and at a second end of the first supplemental member. The second supplemental member has a second end pivotally coupled to the second main member. The first main member includes first, second, and third cross-sections spaced the second cross-section comprising slot that allows for the passage of the first supplemental member through the first main member, wherein the first cross-section differs from the second cross-section.

A retractable sun shade, comprising at least one fabric section affixed to a boom, the boom supported and slideably engaged to a track at an intermediate portion of the boom, the track supported by a frame, and at least one flexible drawing element affixed to the boom at the intermediate portion, for drawing the boom in a first direction along the track to extend the sun shade and for drawing the boom in an opposite direction along the track to retract the sun shade.

A screen device (1), comprising a screen roller (2), a screen (3) which can be rolled up and unrolled hereon, an end lath (4), which is fitted to an opposite side of the screen (3), and a tensioning system (8) to tension the screen (3) in the roll-up and unrolling direction, the tensioning system comprising on each lateral side of the screen (3) a band wheel (5) next to the screen roller (2), a tensioning cord (6), which can be rolled up and unrolled hereon and which, at its end away from the band wheel (5), is fastened to the end lath (4), away from the screen roller (2) a reversing wheel (7), via which the tensioning cord (6) is turned, and a spring sub-system (18), which comprises at least one spring element (9) for keeping the respective tensioning cord (6) under tension, wherein at least one of the spring sub-systems (18) comprises adjustors (10, 11, 14, 13, 16) for adjusting the spring force of the spring element (9).
