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 relates to a blocking system (1, 1') associable to a roller awning having an end edge fixed to a winding roller and the opposed end edge associated to a terminal (3) comprising a tubular body whose end portions (3A) are adapted to slide inside guides (2) for moving said awning between a wound position and an extended position, wherein said terminal (3) of the roller awning is placed adjacent to the lower stop ends (2A) of said guides (2). The blocking system (1, 1') comprises first coupling means (40) comprising a pair of engaging elements (4, 4'), each associable to a respective end portion (3A) of the terminal (3) of the roller awning and capable to move between a first position, wherein said end portions (3A) of the terminal (3) can slide freely within said guides (2) and a second position, wherein they cooperate with second coupling means (50) associable to said lower stop ends (2A) of said guides (2) for removably blocking the awning in the extending position. In particular, said first coupling means (40) further comprise driving circuits (100), each comprising first actuation means (6) and driving means (44), said driving means (100) each being connected to one of said engaging elements (4, 4'), said second coupling means (50) comprise second actuation means (7) adapted to interact with said actuation means (6) for triggering said driving means (44) so that said engaging elements (4, 4') move automatically between said first position and said second position.
摘要:
The adapter module with compensation springs consists of an internal adapter module (1) splined to the drive shaft of the tubular motor and of an external adapter module (4) splined to the roller tube coupled to the internal adapter module by means of at least one spring (5). The internal adapter module (1) and the external adapter module (4) are constructed in such a way that some play is left between the two, thereby allowing their mutual rotation. The spring (5) acts in such a way as to generate a temporary difference between the angular velocity of the internal adapter module (1) and the angular velocity of the external adapter module (4) at the moment in which the weight force bearing down on the roller tube is cancelled out.
