Definitions

  • the present invention relates to a supporting framework, which has been specifically designed for sun curtains and the like.
  • Prior commercially available sun curtains conventionally comprise a box-like body, to be fixed to a fixed structure or construction and supporting the curtain cloth winding roller.
  • a pair of compasses arms are pivoted for supporting the front coupling portion coupling the curtain end portions and which can be extended for unwinding the curtain and folded again to be coupled to the box-like body and fully withdraw or wind the curtain.
  • the articulated joint provided in the central portion of the arms is made by a female-male coupling, including projecting elements.
  • gaps are formed which can be dangerous for a user accidentally putting his/her hands in said gaps, and moreover the curtain cloth can be undesirably gripped during the operating steps thereof.
  • a further problem of the prior art approaches is that the male and female element of the arm central articulated joint comprises end pieces thereon the tubular arms can be locked by riveting, bolts or the like, which would require both to apply a cumbersome projecting element and a coupling operation which cannot be easily and quickly performed.
  • the document FR-A-2 687 186 discloses a supporting framework according to the preamble of claim 1.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a supporting framework specifically designed for sun curtains and the like, which does not require any projecting elements which could be dangerous as the arms are operated for opening and closing.
  • a main object of the present invention is to provide such a supporting framework, in which the coupling to the central articulated joint of the tubular element arms can be performed without applying any outer elements such as rivets and the like, while simultaneously providing a firm and accurate connection.
  • Another object of the present invention is to provide such a supporting framework which, owing to its peculiar constructional features, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a supporting framework, specifically designed for sun curtains and the like, which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • the supporting framework specifically designed for sun curtains and the like, according to the invention, comprises a box-like body 1 of a per-se known type, which can be coupled to a fixed structure or construction 2 and which supports a pair articulated arms 3 which, at the other end portions thereof, are coupled to a front portion 4.
  • the articulated central joint arranged on the compasses arms 3, comprises a female element 11 and a male element 12, which are so constructed as to present a flush surface through the overall angular positions assumed by the articulated joint.
  • the female element 11 is provided with a disc lugs 13, arrange spaced from one another and connected by a throughgoing pin 14.
  • the body of the female element 11 comprises a fitting end-piece 20, which will be disclosed in a more detailed manner hereinafter.
  • the male element comprises a pair of inner discs 16, which are axially adjoining the disc lugs 13 and which are coupled by a coupling pin 14.
  • the male element 12 is also provided with an end-piece 20 which will be disclosed hereinafter.
  • a contoured casing 17 operating as a supporting and guide element for the tension strip coupled to resilient means for causing the arms to be extended.
  • the arms 3 are made of tubular section members 30, of a substantially oval configuration, and which are provided, in their inside, with a plurality of tooth element 31 engaging in grooves 32, formed on a respective face of the end-pieces 20 and inside the hollow 33 provided on the other faces of the end-pieces 20.
  • the groove 32 and sidewalls of the hollow 33 are made with the engagement walls with the tooth elements, providing a changing of the slanting of the laying plane, thereby, as the section member 30 and end-piece 20 are pressure coupled, the fins are bent to provide a deforming effect.
  • Said fins are partially turned thereby to firmly clamp the section member 30 on the end-piece 20, to provide a firm coupling without the need of using screws or rivets.
  • the tooth element 40 have a rectangular trapezium configuration, with the raising ramp facing the free end of the end-piece 20.
  • said tooth elements 40 and 41 provides a further safety element, since said tooth elements would prevent the fins or tooth elements 31 deformed by slanting the wall of the groove 32, from disengaging and causing a labile connection.
  • the tooth elements 40 and 41 will provide a deformation localized on the section member 30 thereby enhancing the locking of the section member and end-piece.
  • Such a deformation is carried out by gradually turning the contacting surfaces.
