摘要:
A winding shaft drive (1, 1A, 101, 101A, 102, 102A) is arranged for operating a retractable covering for an architectural opening. The winding shaft drive includes an at least partially hollow winding shaft (7); a driving member (3, 103) for inducing rotation to the winding shaft; and a shaft brake adapted to be operated by the driving member. The shaft brake includes a preassembled module (5) for accommodation in the at least partially hollow winding shaft (7) and has first coupling means (67) on one axial end thereof for transmitting rotative forces and second coupling means (69) on the same one axial end for transmitting non-rotative stationary forces. The driving member has a driving hub (11, 111) for removably coupling to the first coupling means (67) and a stationary connector (17, 17A, 117, 117A) for removably coupling to the second coupling means (69). A shaft brake module (5) and a driving member (3, 103) are specifically adapted for use in the winding shaft drive.

A blind 1 suspended from a carrier tube has a transmission assembly 3 mounted at one end of the carrier and an operating wand 4 pivotally connected to the transmission assembly for operating the blind. The wand includes a stem 5 with an axis 6, a first a crank handle 7 disposed on one side of the stem axis, and a continuous second crank handle 8 disposed on the opposite side of the stem axis. The wand hangs symmetrically, is easier to operate than a single crank handle, and is convenient to package.

Es handelt sich um eine Gurtführung für ein Gurtband o.dgl. Zugelement einer Verdunkelungsvorrichtung, insbesondere eines Rollladens, zur Befestigung an Rollladenkästen, mit einer Austrittsöffnung für das Gurtband und mit Befestigungsbohrungen. Um eine Gurtführung zu schaffen, mit der einerseits eine leichtere Führung des Gurtbandes am Rollladenkasten möglich ist und die anderseits individuell an vorhandene Lochabstände oder sonstige Gegebenheiten für die Befestigung derselben angepasst werden kann, besteht die Gurtführung (1) aus einem im wesentlichen U-förmig ausgebildeten Grundträger (3), in dem zwischen den beiden seitlichen Schenkeln (4, 5) des Grundträgers (3) eine Umlenkrolle (6) für das Gurtband (2) gelagert ist. Dabei sind in dem die beiden seitlichen Schenkel (4, 5) verbindenden Steg (7) eine Eintrittsöffnung (8) für das Gurtband (2) sowie unterhalb der Umlenkrolle (6) eine Befestigungsbohrung (9) vorgesehen. In dem Steg (7) ist ein vom oberen Rand (10) des Steges (7) bis in die Eintrittsöffnung (8) verlaufender Schlitz (11) vorgesehen, an dem ein Haltestück (12) mit einer Befestigungsbohrung (13) verschiebbar geführt ist. Am unteren Ende (18) der Gurtführung (1) bzw. des Grundträgers (3) ist zwischen den beiden Schenkeln (4, 5) eine stiftförmige Führungsachse (19) gelagert, wobei zwischen der Führungsachse (19) und einem vom unteren Ende (20) des Steges (7) rechtwinklig zu demselben verlaufenden weiteren Steg (21) die Austrittsöffnung (22) für das Gurtband (2) gebildet ist.

A motorized blind (10) having a pull cord (18). The pull cord is mechanically connected to an electrical switch (48) in a headrail (12) of the blind, the switch being electrically connected to an electric motor (30) within the headrail. The pull cord (18) also extends outwardly of an end of the headrail and then outwardly and downwardly of the blind through a hole (50) in the front of an end cap on the headrail.

A bead chain type pull cord mechanism for a window shade includes a frame, a shade, a shade driving mechanism, and a bead chainfor driving the shade through the shade driving mechanism. A barrel (5) is mounted to the frame at a location corresponding to the bead chain. A sliding block (7) is slideably received in the barrel (5) and connected to a handle (8) mounted outside of the barrel (5) by a link extending through a slit (6) in the barrel (5). The bead chain is wound around a fixed pulley mounted to an end of the barrel (5). The sliding block (7) is fixed to a section of the bead chain received in the barrel (5).

Operating system (1) for rotatably controlling retraction and deployment of an architectural ' covering. The operating system includes a drive pulley wheel (3) having a circumferential rim (5), a length of looped drive cord (9) operatively engaged with the pulley wheel (3) about its circumferential rim (5) and having depending portions on opposite sides of the pulley wheel (3), a cover (7) co-extensive with a portion of the circumference of the pulley wheel (3) and at least one stopper (19) attached to a portion of the length of the drive cord (9) and adapted to engage the cover (7) to stop rotation upon a predetermined amount of rotation of the pulley wheel (3). The pulley wheel is provided with a cavity (17) on its toothed circumference for receiving the at least one stopper (19) to prevent it from engaging the cover (7).
摘要:
The invention concerns a transverse winding mechanism for blinds designed to be mounted in a narrow recess defining a window frame in a building, which comprises a front crank exit for winding up the blind. The specific configuration of said winding mechanism enables interference between the cable and the conical gearing teeth to be avoided by separating the latter from the space designed to receive the cable when it is being wound. Said winding mechanism may have various configurations and further comprises a projecting element arranged in the inner region of the take-up reel which enables the cable to be fixed without having to provide through orifices of the axis of the reel at its upper wing.
