摘要： The support framework for any type of rolling curtains and in particular for window opening protecting mosquito- nets is of the type including a box containing a longitudinally grooved hollow roller with a screen - the actual curtain - wound around it, at the two box ends a first and second head being fitted for the free support of said roller and of said curtain elastic uprolling devices and vertical guides for said screen edges and hooking elements for kkeping the curtain tight when in straight position. The second one of said heads is supplied with a device for a quick and final stretching adjustment of said screen and is fitted on the said framework after cutting the box and associated parts according to the desired length, thus allowing direct framework mounting without previous inspection for the necessary measurements.

摘要： A curtain winding up winch is provided with a control device with bevel gears (9) (11) having a 1:1 ratio. In order to allow lifting the curtain and ensuring the irreversibility of such action the winch is provided with an irreversibility device formed by a helical spring (33), which is enclosed within a block (41) rigidly connected to the handgrip (7) and is engaged on a sector bushing (15) having a rotational clearance relative to the hub (37) of the first control bevel gear (9). Coaxially mounted on the second bevel gear (11) is a control shaft (13) coaxial to the curtain winding up roller (17) and rigidly connected to it; extending between said shaft (13) and the curtain winding up roller (17) is a double helical spring (27) fixed at one end to the control housing (7), and at the other end rigidly connected at (29) to the curtain winding up roller (17).

摘要： A torque-adjusting device for use in a roller blind is equipped with an easily operatable handle ring (15), by the help of which a roller assembly can have its initial torque adjusted to the optimum value which it is set up in the permanent position. The device includes a brake drum (12) secured to a mounting bracket (11) a a coil spring (13) fitted on the brake drum, an intermediate disk (14) disposed between the coil spring and the handle ring. The intermediate disk is integrally coupled with a stator (2) to which an end of the spring-motor is fixed. The handle ring has an inner tung (26) inserted between the opposite projecting ends (20, 21) of the coil spring in slit (25) in the outer periphery of the disk, therefore the coil spring permitting a rotational transmission from the handle ring side to the stator side but suppressing the counter transmission.

摘要： Der aus Leisten (20) gelenkig zusammengesetzte Rolla den(5) ist an mindestens einem Ende in einer spiralförmigen Nut (11) geführt und wird durch ein von einem Antrieb (7) in Bewegung gesetztes Antriebsrad (15) auf- oder abgerollt. Am Antriebsrad (15) sind zeitweise in die Nut (11) ragende Mitnehmer (16) angeordnet, die an Nocken (21) an den Enden der einzelnen Leisten (20) angreifen. Die Nut (11) kann als langegestreckte Spiralnut ausgebildet sein, wodurch der beim Aufrollen des Rolladens (5) entstehende Wickel verhält nismässig schmal ist, so dass er einerseits den Tageslichtein fall nicht einengt und andererseits in bestehenden schmalen Nischen (4) untergebracht werden kann.

摘要： A roller door including an elongate, flexible closure member (12), a hollow roller (13) to which one end of said closure member is secured, and means for rotating said roller whereby said closure can be wound onto said roller to open said door and unwound from said roller to close said door, said roller in use being positioned adjacent to the upper edge of the doorway, a spindle (16) extending in said roller (13), torsion springs (21) coupling the roller and the spindle for rotation together while affording limited relative rotation of the spindle and roller accompanied by corresponding stressing of the torsion spring (21), drive chains (34) extending parallel to the direction of movement of the closure member and being in driving engagement with said spindle and idler wheels (35) positioned in use adjacent the lower edge of the doorway and the free end of the closure member being secured to said drive chains (34) at points along the length of the drive chains (34) such that said torsion springs (21) are stressed in a direction to rotate said roller (13) relative to said spindle (16) to wind said closure member (12) into said roller and thus apply tension to the closure member between the roller and its point of anchorage on the drive chains (34), and a motor arrangement (27,28) for rotating the roller and thereby the spindle to wind or to unwind the closure member.

摘要： A screen-positioning device for use in a roll blind com. prising a fixed shaft (20) sustained by a bracket (12) for rotatably supporting the screen-roll (10), an extension shaft (21) secured to the fixed shaft (20) and formed with a drum portion (22) and a screw-bolt portion (23), a torsional spring (25) having one end thereof fixed to the drum portion (22) and the other end loosely turning around the screw-bolt portion (23), a screw-nut (26) mounted on the screw-bolt portion (23) and formed with a conical surface (28) for fitting engagement with the spring (25). When the screen (30) is raised to a predetermined height, the conical surface (28) is so engaged with the free end portion of the spring (25) that the spring (25) is caused to tighten on the drum portion (22) Whenever the screw-nut (26) is engaged with the spring (25). it undergoes the spring-back force to be rotated in the direction in which the screen (30) is lowered The fixed shaft 120) is supported by the bracket (12) with the intervention of a one-way clutch mechanism comprising a brake drum (38) secured to the bracket (12). a brake coil spring (36) wound around the brake drum (38). a sector (34) secured to the fixed shaft (20) and fitted on the brake coil spring (36), a slit (35) formed in the periphery of the sector (34) to receive opposite ends (36a, 36b) of the brake coil spring (36), a dial-ring (40) loosely fitted on the sector (34) and provided with an inner projection (41) put in between the both ends (36a, 36b). The roll-up height of the screen is determined by an axial position of the screw-nut (26) on the screw-bolt portion (23). The axial position is easily adjusted by use of the dial-ring (40), which is rotatable together with the fixed shaft (20) or extension shaft (21) to move the screw-nut (26) along the screw-bolt portion (23).
