Abstract:
1. An elongated element for the frame of a panel system comprising a flexible sheet material, comprising: a main profile including a connection portion adapted to be fixed to a support surface through connection means, and further including an elongated appendage extending from the connection portion, the elongated appendage having a winding end adapted to be surrounded by a portion of the sheet material close to an edge thereof; an auxiliary profile movably associated within the main profile in order to be translatable with respect thereto, and associated with means for anchoring an edge of the sheet material, the auxiliary profile being substantially L-shaped and having a primary branch adapted to be arranged parallel to the elongated appendage of the main profile, and a secondary branch generally perpendicular to said primary branch; and drive means for controlling the position of the auxiliary profile with respect to the main profile and for tensioning said sheet material, which drive means comprise an elongated groove extending axially in a side of the main profile facing the auxiliary profile, at least one screw member arranged so as to cross the primary branch of the auxiliary profile and having a respective free end portion slidably received in said groove, as well as a hook formation in the main profile facing the elongated appendage and defining an elongated cavity parallel to the elongated groove and opposite thereto with respect to the auxiliary profile, in which cavity the secondary branch of the auxiliary profile is slidably received, the length of the secondary branch of the auxiliary profile being substantially equal or less than the distance between the hook formation and the elongated appendage so that the auxiliary profile can be inserted in place into the main profile according to a translational movement parallel to said elongated appendage, whereby when the sheet material is anchored to the auxiliary profile and said at least one screw member is operated for tensioning the sheet material, separation of the auxiliary profile from the main profile is prevented by virtue of the engagement of said free end portion of said at least one screw member in said elongated groove and of the engagement of the secondary branch of the auxiliary profile in said elongated cavity.
