Die Erfindung betrifft ein Tor, insbesondere Hubtor, zum Verschließen einer Öffnung in einer Wandung, insbesondere in einer zwei verschiedene Temperaturzonen voneinander trennenden Wandung, mit einem bewegbaren, flexiblen Torblatt (22), das mehrere separate, flexible Torblattlagen (28a-d) umfasst, die derart geführt sind, dass sie im geschlossenen Zustand des Tores (10) voneinander beabstandet sind, und mit mindestens einer Aufwickelwelle (18, 20), auf die das Torblatt (22) zur Öffnung des Tores (10) aufwickelbar ist. Die Erfindung ist dadurch gekennzeichnet, dass zwei benachbarte Torblattlagen (28b,c) durch mindestens einen Abstandshalter (26) miteinander verbunden sind, der im geschlossenen Zustand des Tores (10) für einen durch den Abstandshalter (26) definierten Abstand der beiden Torblattlagen (28b,c) mindestens im Bereich des Abstandshalters (26) sorgt.

The present invention relates to an automatic tensioning system (100) adapted to cooperate with an awning sheet of a motor-driven roll-type awning comprising a first electric motor (11) comprising a rotating shaft integral with a winding roll-bar (1) and a motor head (11A), a second electric motor (12) associated with a tensioning roll-bar (2), said awning sheet (3) being secured with a first edge portion to said winding roll-bar (1) and operatively associable with the edge portion opposite to said tensioning roll-bar (2), said awning sheet (3) being movable between a retracted position wherein it is completely wound about said winding roll-bar (1) and an extended position, wherein it is at least partially unrolled from said winding roll-bar (1), control means (20) connected to said first and said second electric motor (11, 12) to control the movement of the sheet (3). In particular, said system (100) comprises a support bracket (7) whereon said motor head (11A) of said first electric motor (11) is rotatably mountable, elastic means (9) secured to said support bracket (7) and operatively connectable to said motor head (11 A) for biasing its rotation, position detecting means (25), comprising at least a detecting element, adapted to be integrally associated with said motor head (11A), and reference means (50) arranged integral with said support bracket (7) and operatively connectable to said control means (20). Said reference means (50) are adapted to cooperate with said position detecting means (25) for generating a signal when, due to a change of the tensioning condition of the awning sheet (3) with respect to a pre-set tensioning condition, the couple applied on said motor head (11 A) causes its oscillation, said control means (20) being adapted to receive the generated signal and modify or block the movement of the rotating shaft of said first electric motor (11) or said second electric motor (12) in response to the received signal so that the pre-set tensioning condition of the awning sheet (3) is restored. Moreover, the present invention is related to a method for maintaining or restoring a pre-set tensioning condition of an awning sheet of a roll-type awning.

The present invention discloses a device for rolling up and unrolling a material web (2) on a shaft (1, 15). The device is distinguished by the fact that a first radial spacing (R1) of the material web (2) from a rotational axis of the shaft (1, 15), which first radial spacing (R1) is assigned to any desired unrolled length (L) of the material web (2), differs from a second radial spacing (R2) of a tensioning cable (3, 16) from the rotational axis of the shaft (1, 15), which second radial spacing (R2) is assigned to said unrolled length (L), with the result that the direction and magnitude of a first torque which is exerted on the shaft (1, 15) via the material web (2) differ from those of a second torque which is exerted on the shaft (1, 15) via the tensioning cables (3, 16), in such a way that, on account of the torque difference between the first torque and the second torque, the shaft (1, 15) is driven by a force (F) which is transmitted by means of the tensioning cables (3, 16).

The present invention relates to a roman blind fabric on which loops are formed and a roman blind using the same. More particularly, rings for inserting loop cords thereinto are integrally woven on the back surface of a loop-forming fabric at the time when the loop-forming fabric is woven, and the loop-forming fabric and a roll-up fabric are provided as a double layer to prevent the loop cord from being wrapped around the neck of a child. In order to achieve this, rings (32) for inserting loop cords (31) are woven integrally with a loop-forming fabric (30) in such a manner as to be formed transversely and longitudinally at the time when the loop-forming fabric (30) is woven; the upper end of the loop-forming fabric (30) is fixed to a frame (39); the upper ends of a roll-up fabric (36) which is placed on the back side of the loop-forming fabric (30) and a plurality of loop cords (31) are fixed to a winding rod 37; and the lower ends of the loop-forming fabric (30), the roll-up fabric (36) and the loop cords (31) are fixed to a weight (42).
摘要:
A profile for a bottom rail of a roller blind, which profile (1) has a tubular shape with an inner surface (2) and an outer surface (3). The wall of said profile (1) is provided with a longitudinal groove (5) at its outer surface (3) for attaching a skirt of said roller blind. The groove (5) has a cross-section narrowing from a base towards said outer surface (3) and the inner surface (2) of the profile (1) defines a space for a further roller blind, whereby the wall of the profile (1) is provided with a longitudinal blind opening (4) substantially opposite said groove (5).
