Publication number: 20080289775Abstract: A support assembly is provided for a roller tube that holds sheet material. The support assembly has opposed first and second mounts adapted to support the roller tube when rotatably coupled to the mounts. The mounts can include slides having a slide member that slides within a slide bracket. A support cradle is disposed between the first and second mounts. The support cradle is configured to support the roller tube along a length thereof. Various spring elements can be arranged to apply a force to the roller tube in an upward direction when the roller tube is positioned to dispense material therefrom in a downward direction, thereby preventing the sheet material from telescoping and/or from dragging or binding against the support cradle as it winds and/or unwinds, while also keeping the material from being wound tighter at the ends than across the rest of the roller tube.Type: ApplicationFiled: May 15, 2008Publication date: November 27, 2008Inventor: Stephen Lukos

Patent number: 6279639Abstract: A separating mechanism 13 is provided which includes a winding shaft 19 that is rotatably supported in a housing 14. A separating net 15 can be wound on the winding shaft 19 and can be stretched in the space between the housing 14 of the separating mechanism 13 and the roof lining of a passenger car. Since the winding shaft 19 generates a greater torque that the user must counteract with increasing draw-off of the separating net 15, a drive mechanism 18 is provided that provides that from a predetermined draw-out length onward the drive torque for the winding shaft 19 is switched to a reduced level. This switch-over is either brought about as a second, weaker drive spring 39 is activated, or as a second drive spring 93 is switched parallel to the drive spring 38 for the winding shaft 19. The two auxiliary springs 39, 93 operate, however, only over a limited turning range of the winding shaft 19.Type: GrantFiled: June 15, 2000Date of Patent: August 28, 2001Assignee: BOS GmbH & Co.Inventors: Werner P. Schlecht, Beate Krause, Holger Seel, Marina Ehrenberger

Patent number: 5658037Abstract: A retractable closure includes a flexible sheet that is comprised, at least in part, of torsion spring material that causes the flexible sheet to form a roll when retracted. The flexible sheet preferably is of sufficient length and width, when extended, typically to close, cover, curtain or partition a selected area. In preferred practice, the torsion spring material comprises a plurality of torsion spring members carried in separate pockets of the flexible sheet at intervals spaced across the width of the flexible sheet. The flexible sheet is unrolled and extended lengthwise by pressurizing and expanding a plurality of elongate fluid-pressure-expansible members that are connected to the flexible sheet, with the expansible members extending along a selected portion of the length of the sheet at intervals spaced across the width of the sheet--preferably with each expansible member carried in a separate pocket of the flexible sheet.Type: GrantFiled: January 13, 1995Date of Patent: August 19, 1997Inventors: Jeffrey L.

Patent number: 5437324Abstract: The present invention provides a roller shade with a variable load brake and, in a modification thereof with a lift assist. The load brake includes a compressible spring surrounding a threaded rod, the spring acting against a traveling nut mounted on the rod. The compressive friction of the traveling nut against the threads of the threaded rod continually varies during raising and lowering of the shade to provide the variable load braking capability. The lift assist uses at least one torsion spring, also associated with a shaft and coupled between a nonrotating flange and a nipple rotationally anchored to the shaft. The torsion spring system is increasingly loaded when the shade is lowered.Type: GrantFiled: January 19, 1994Date of Patent: August 1, 1995Assignee: Newell Operating CompanyInventor: Alan R.

Patent number: 5271446Abstract: A multi-purpose automatically rewindable sun-shade devised to have a quite long resilient curtain which is wound around a winding tubular shaft when it is not in use. The curtain may be pulled out to a needed length for use and rewound automatically on the winding shaft by twisted coil springs. The sun-shade comprises an elongated winding tubular shaft for winding a long curtain thereon, two immovable rods adapted to extend in the interior of the winding shaft, two coil springs fitting around the immovable rods in the winding shaft to generate tension when twisted. The tension force rotates the winding shaft to rewind the curtain after use. The shade has two sleeves assembled around the winding shaft and forming a central through hole for a square end of each of the immovable rods to pass through to engage a central square hole in each of two shaft caps assembled with the two sleeves so that the sleeves and the winding shaft can rotate together between the two shaft caps.Type: GrantFiled: August 11, 1992Date of Patent: December 21, 1993Inventor: Chyi-Ming Hwang

Patent number: 3955611Abstract: An awning construction particularly adapted for mounting on a mobile home. The awning includes an awning shade having one end fixed to an outside wall of the mobile home, and the other end of the awning shade is attached to an awning roller, which roller is pivotedly connected to the same outside wall. The awning roller includes an elongated torque rod which is nonrotatably connected to a pair of support arms. The support arms are pivotedly connected to the outside wall. A tube is rotatably mounted on the torque rod and is secured to the other end of the awning shade. A torsion spring connects the torque rod with the tube to rotate the tube relative to the torque rod and holds the tube up against the wall of the mobile home in its normal condition. A lock releasably locks the tube relative to the torque rod to allow the tube to stay selectively in an extended position away from the side wall.Type: GrantFiled: August 5, 1970Date of Patent: May 11, 1976Assignee: C & K Sales CorporationInventors: John W.
