Abstract:
The present invention relates to a mechanism for automatic opening of rolling doors (20) in case of emergency consists of: a roller (21) that is a hollow round roller and has at least one first positioning hole (211) which is formed at an one end of the roller; a rotation axis (22) has a diameter smaller than the diameter of the roller (21) and coaxial rotatable inside the roller (21) and has two rotation ends (222) outside of the roller; at least one spring (24) has an one end (241) fixed to the rotation axis (22) and the other end (242) is fixed to the internal surface of the roller (21), when the rotation axis (22) rotates relatively against the roller (21) in the opposite direction of the rolling door body so that, when convoluted spring (24) generates elastic accumulated energy of spring (24); an elastic accumulated energy fixing unit (25) that is placed on a rotation end (222) of the rotation axis (21) and has a first positioning hole (211) of the roller (21) to fix elastic accumulated energy; and an activator (26) activates to release elastic accumulated energy, thereby it produces the efficiency of automatic opening of the rolling door.
Abstract:
Die Erfindung betrifft ein System zum Abwickeln der Plane im Kofferraum eines Fahrzeuges. Dieses System besteht aus einer Feder (1), einer zur Plane angeschlossenen Röhre (2), einem einzulegenden Profil (3) und einem Mitnehmer der Feder (1), wo die Feder (1) innen des einzulegenden Profils (3) angeordnet ist, das in der Röhre (2) gelagert ist. Die Feder (1) ist durch den Mitnehmer der Feder (1) zur Röhre (2) befestigt, wobei der Mitnehmer der Feder (1) gleichzeitig zur seitlichen Innenverkleidung des Kofferraumes befestigt ist. Das Profil (3) besteht aus drei symmetrischen Zipfel und jedes der Zipfel eine Bogenform aufweist. Die Darstellung der Erfindung liegt darin, dass gerade ein Zipfel mit einem freien Ende mit dem zweiten Zipfel und mit dem zweiten freien Ende mit dem dritten Zipfel verbunden ist und gleichzeitig der zweite und der dritte Zipfel gegenseitig nicht verbunden sind. Die Zipfelverbindungsstellen sind im Kontakt mit der Feder (1), wobei die freien Enden des zweiten und dritten Zipfels im Kontakt mit der Feder (1) und vorgespannt sind, wodurch die Feder in einer vorbestimmten Position fixiert wird.
Abstract:
The invention relates toa spring operated roller blind system, wherein the roller blind (1) comprises an adjusting mechanism (30) for adjusting an end position of the flexible sheet member. The adjusting mechanism comprises a spindle (36) and a connecting member (31) that is connected to the roller shaft for rotation around the spindle. The adjusting mechanism further comprises a first bearing (7) for the roller shaft that defines a first end position for the connecting member (31). At least one of the bracket connectors (21) comprises a pin (33) for detachable mounting in a cooperating recess (35) on the adjusting mechanism, wherein the pin and the recess have an unround cross section.
Abstract:
A rail, such as a head rail, for an architectural covering. The rail includes a housing having elongate walls extending along a length of the housing and defining therebetween a width of the housing. A drive shaft is rotatable about a drive axis extending along the length of the housing and is configured to wind and unwind lift cords or blind material of the architectural covering. A spring assist module, e.g. a spring motor has an output shaft rotatable about an output axis with rotation of the drive shaft. The spring assist module is mounted in the housing with the output axis parallel to the drive axis. The spring assist module extends outwardly in a width direction beyond the width of the housing.
Abstract:
A spring-holder box of a roller shutter and related kit and method of assembly, according to which the box (4) comprises two annular shells (9) rigidly connected to each other by a plurality of crosspieces (10), interposed between the annular shells (9) with their longitudinal axes (10a) parallel to the central shared axis (9a) of the annular shells (9); each crosspiece (10) having a central body (11) and, for each longitudinal end, a pair of teeth (13) coupled to respective slots (14) of the annular shells (9); each tooth (13) passing through the respective slot (14) and extending beyond the slot with a relative head portion (16), which, when completing assembly, is deformed by twisting relative to the remaining portion of the tooth (13) positioned inside the slot (14).
Abstract:
A connector for a blind control mechanism, said mechanism including: i) a cylinder rotatable relative to two or more different shafts; ii) drive means connected to the cylinder and being operable to rotate the cylinder in either a blind extending direction or a blind retracting direction; and iii) at least two biasing means connected to said cylinder, each said biasing means being responsive to rotation of the cylinder in a blind extending direction to store energy and being responsive to rotation of said cylinder in a blind retracting direction to release said stored energy and thereby apply a turning force to the cylinder, said turning force acting in the blind retracting direction; said connector having a body for coupling an end portion of one of said biasing means to one of said shaft portions, and for coupling respective end portions of two adjacent said shafts together.
Abstract:
A spring drive system (15) for window covers (10, 20) is disclosed, which comprises a flat spring drive (26, 31, 41) and the combination whose elements are selected from (1) a band transmission (21) which provides varying ratio power transfer as the cover is opened and closed; (2) a gear arrangement (60) having various gear sets which provide frictional holding force and fixed power transfer ratios; and (3) a gear transmission (70) which provides fixed ratio power transfer as the cover (10, 20) is opened or closed. The combination permits the spring drive force at the cover (10, 20) such as a horizontal slat (10) or pleated or box blind (20) as the cover is opened and closed.
