Abstract: A door assembly includes: a rotatable curtain deployment member positionable about a structure opening; a curtain panel fixed to the curtain deployment member, the curtain being movable, upon rotation of the curtain deployment member, between a retracted position and an extended position, the curtain panel having at least one portion of increased thickness; a rotatable balancing strip member configured to substantially parallel with the curtain deployment member, and configured to rotate synchronously therewith in a common rotational direction, and a balancing strip having a first end attached to the balancing strip member, and a second end attached to the curtain deployment member and axially spaced from the portion of increased thickness. When the curtain panel deploys to the retracted position, the balancing strip deploys to the curtain deployment member, and when the curtain panel deploys to the extended position, the balancing strip deploys to the balancing strip member.

Abstract: A damping device for a window covering includes a headrail, a covering material, and a driving device. The driving device is located in the headrail to raise and extend the covering material. The damping device is provided in the headrail, and includes a metal member and a magnetic member, wherein at least a magnetic pole of the magnetic member faces the metal member. The metal member is located within a magnetic field of the magnetic member. Either one or both of the metal member and the magnetic member can be driven by the driving device to cause relative movement therebetween. The damping device is able to provide a desired damping effect regardless of changes in temperature or even after prolonged use. The damping device provides a damping effect which slows down the rotation of the metal member and the movement of the covering material.

The rotation driving device (3) can actuate a curtain reeling drum (4A) to rotate a curtain cloth (7) or actuate a reeling rope device (4) to rotate a curtain cloth or shade (7). A reverse rotation releasing device (5) and a resilience reverse rotation mechanism (14) are connected to the rotation driving device (3). The rotation driving device (3) is comprised of a pull rope rotary disc (3c), a unidirectional clutch device (6) connected to the pull rope rotary disc (3c), and a rewinding spring (3e) mounted between the pull rope rotary disc (3c) and a pull rope rotary disc box (3a). Thus, only one cord is sufficient to control opening of the curtain cloth or shade (7), and reverse rotation of the curtain reel drum (4A) is not adversely affected by the rotation driving device (3). It is convenient to use while avoiding injury to children.

Abstract: The invention relates to a shading roller blind for a motor vehicle window, with a flexible sheetlike structure (40) which can be wound up on and unwound from a winding shaft (43) and can be moved with the aid of at least one linear guide means (5, 105) from a stowed position into an at least partially unwound protective position, and with a releasable blocking device (7) by means of which the linear guide means (5, 105) can be arrested in at least one position, in particular the protective position and/or stowed position, the blocking device (7) comprising a push-push lock.

Abstract: A retractable barrier includes a rollup or otherwise retractable panel that can extend between two spaced apart support members. When not in use, the panel can retract onto one of the support members to permit passage. The barrier provides substantial impact resistance by having the reactive force of the impact transfer directly between the barrier's retractable panel and its support members without having to rely on the strength of the panel's take-up roller or the strength of the roller's anti-rotation mechanism. This can be accomplished by having a slot-engaging stop member mounted directly to the panel itself. The stop member is preferably a pipe, rod, bar or some other vertically elongate member that can broadly distribute an impact reactive force over the height of the panel. In some embodiments, the barrier can be set for various doorway widths by simply repositioning the stop member's location on the retractable panel.

Abstract: A method is disclosed of installing a barrier device at a passageway. The method includes attaching a barrier housing containing a retractable barrier to a structural element on one side of the passageway, extending the barrier a desired distance from the barrier housing, with the barrier so extended, setting an extension limit of the barrier to prevent subsequent extension of the barrier beyond the desired distance from the barrier housing and, with the extension limit set, retracting the barrier into the housing. The set extension limit can permit subsequent retraction and re-extension of the barrier up to the set extension limit.

Abstract: An improved take-up mechanism for a roll-up type screen, wherein the screen is pulled out to a desired length, and then by simple pulling and releasing, rolled up on the shaft. The shaft is automatically locked at the desired length of screen by engagement of a lock roller projected by a cam magnet. During pulling out operation, a magnet, a covering yoke and a cylinder disposed therebetween do not move with respect to each other, whereas during roll up operation under force of the wound up spring, the cylinder rotates under control of the magnetic field between the yoke and magnet to control the speed of roll up. The improvement comprises lock rollers on a cam magnet, one way clutches, roll holder, and ring lock for the rollers, together with the magnet to produce the above effects.

Abstract: A braking device for use in a spring-motor type roller blind comprising cam and brake means interposed between a rotatable tube and a fixed shaft in substitution for a centrifugal clutch. The means has a brake drum mounted on the fixed shaft, a coil spring brake mounted on the brake drum, a cam sleeve mounted on the brake drum and formed with a Y-shaped cam groove, the coil spring brake having one end fixed to the cam sleeve and the other end disposed under the bottom part of the Y-shaped cam groove, and a cam casing integrally mounted in the tube and provided with a cam pin for engagement with the cam groove. The cam pin relatively moves along the cam groove and pushes either of the opposite ends to loosen the coil spring brake when the screen is drawn and when it is released after drawn from a position except the uppermost position and fasten the same on the brake drum when it is released after drawn from the uppermost position.
