A sheet material arrangement having a flexible primary sheet material and an edge member with two legs pivotably connected together. The first leg has two outer portions of a band-shaped secondary sheet material and is connected to the primary sheet material along an edge portion. A central portion of the secondary sheet material is looped around an insert transversely to the longitudinal direction of said secondary sheet material and, together with this insert, forms a second leg which is connected to the first leg so as to be pivotable about a pivot axis. In a pivoting position, with the legs arranged approximately parallel, the edge member and the sheet material can be rolled up on a winding shaft. In a further pivoting position, the legs form an angle of inclination different than 0°, with the result that the second leg is useable for guided displacement in a guide rail.

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).
摘要:
A method and system for creating a shaded area using retractably mounted photovoltaic cells is disclosed that utilizes an energy and shade producing canopy of retractable photovoltaic cells or panels that is deployed to create shade and electricity when desired and retracted when not in use.
摘要:
There is described a canopy system comprising two or more parallel elongated rods, one or more canopy pieces having two parallel edges, two or more elongated bars connected to each of the two or more parallel elongated rods and attached to each of the two parallel edges of the one or more canopy pieces, and at least one connection mechanism attached to each of the elongated rods having a connector that is capable of being suspended from a support. The elongated rods may include at least one lower cavity having two channels each configured to detachably and slidably receive each of the elongated bars. The lower cavity may have a groove that is configured to detachably and slidably receive an accessory. The elongated rods each may include at least one upper cavity configured to detachably and slidably receive each connection mechanism and a second accessory.

The present invention relates to a retractable wall system (12) which may include an elongated member (300). The elongated member may include a front wall (302), a rear wall (303) spaced from the front wall, a bottom wall (304), a first top wall (326a) adjacent the front wall, a second top wall (326b) adjacent the rear wall, and a channel (86) between the first top wall and the second top wall. The channel may comprise a first side wall (86a), a second side wall (86b), a first ledge (86c), and a second ledge (86d). The first and second ledges may define a slot (88) between the first side wall and the second side wall. The elongated member may further comprise a conduit (466) disposed between the front wall (302) and the rear wall (303) that is connected to the channel via the slot.
