A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The pleated roller shade system comprises a drive system, such as a motor or manual drive system, for controlling of the rotation of the roller tube. The roller shade system may comprise a pleating hem bar that is contained within a hem bar pocket of the shade fabric and has a non-linear shape for causing the shade fabric to hang with a plurality of pleats. The roller shade system may also comprise an elongated pleating assembly mounted parallel to the roller tube and having a fabric-receiving opening that defines a non-linear path. The shade fabric may be received through the fabric-receiving opening and folded by the pleating assembly, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates. The pleating assembly includes a plurality of pleating elements that each have a T-shaped or funnel-shaped structure for causing the shade fabric to hang with the pleats.

A window covering includes a first rail, window covering material, lift cords that extend from adjacent the first rail to the window covering material, and at least one pulley and at least one pulley release device. At least one pulley is positioned so that at least one lift cord passes along that pulley. Each pulley release device is attached to at least one respective pulley to releasably connect the one or more pulleys to the first rail. Each pulley release device is configured to permit the one or more pulleys to which it is attached to release from the first rail when a release force acts on a component of the pulley release device. Preferably, the one or more pulleys are positioned on the outside of the first rail adjacent to the window covering material. The one or more pulleys may also be positioned adjacent to a valance.

A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The system comprises a pleating bar mounted parallel to the roller tube and having a fabric-receiving opening that defines, for example, a serpentine path. The shade fabric is received through the fabric-receiving opening and is folded by the pleating bar, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates. The shade fabric is neatly wrapped around the roller tube (i.e., bunching of the shade fabric is avoided) and is stored out-of-sight when rolled up.

A sunshade includes a roller and a screen. The roller has an intermediate portion, two end portions extending respectively from opposite ends of the intermediate portion, and a screen-stretching portion disposed on an outer surrounding surface of the intermediate portion. The screen has a main body and two lateral portions. The main body is wound on the screen-stretching portion and the intermediate portion of the roller and has opposite ends. The lateral portions are connected respectively to the opposite ends of the main body and are wound respectively on the end portions of the roller.

A self-contained system for protecting building penetrations is disclosed. The system can include a housing containing a take-up roll and a screen made from a flexible, strong fabric-like material suitable for resisting high winds, driving rain, and wind-driven missiles. The system can further comprise a deflector or roller to maintain the angle of deployment of the screen. The system can further include a weight bar attached to the end of the screen to assist in deploying the screen. The system can further comprise a dual pulley system to assist in deploying the screen and to hold the screen in the deployed position. The system can include wipers to clean the screen as it is retracted into the enclosure. The system can further comprise an integrated or separate light control, or “black-out” screen. The system enclosures can comprise various hinged covers to facilitate service, repair, and storage.
摘要:
A method of fastening a flexible sheet-like structure on a tubular winding shaft including: introducing, in a circumference of the tubular winding shaft, at least one aperture which passes through a wall of the winding shaft, a width of the aperture being greater than the thickness of the flexible sheet-like structure, cutting into the flexible sheet-like structure to produce at least one angleable tab, and inserting the tab into the aperture of the winding shaft. Additionally, a roller blind includes a winding shaft and a flexible sheet-like structure fastened thereon.

The present invention is a retractable screen (22) and frame (24) assembly (20). The frame (24) includes a first track (32) and a second track (34) in spaced and parallel relationship to the first track (32). The retractable screen (22) includes a canister (36), a screen cloth (38), a control bar (40), a first glide (42), a second glide (44), and a biasing device (46). The biasing device (46) is disposed between a first end (52) of the control bar (40) and the first glide (42). The first glide (42) is inserted into the first track (32) and the second glide (44) is inserted into the second track (34). The glides (42, 44) slide along the respective tracks (32, 34) while the biasing device (46) biases the first end (52) of the control bar (40) with respect to the first track (32). The biasing provided by the biasing device (46) prevents the control bar (40) from binding with the tracks (32, 34) as the control bar (40) and the glides (42, 44) are slid along the tracks (32, 34).

The invention relates to a device for detecting an obstacle and limiting the force from the primary edge or sill nosing (10) of a flexible apron or curtain (5) in a goods-handling door (1) when the latter comes into contact with an obstacle (14) as it is being closed. The inventive device comprises safety cells (21, 22) which are positioned and fixed close to each guiding device (8) such as to emit a beam F that is directed along a vertical axis outside of the guide (15) so that the beam is interrupted upon deformation of the flexible curtain or apron (5).
