Definitions

  • the present invention relates to a fixing device which allows the easy mounting or dismounting of a fabric such as a canopy fabric on a winding support having a groove.
  • the fabric is fixed to a support, generally a cylinder or a winding shaft, by means of a protuberance which is formed at one end of said fabric. More particularly, this protuberance is obtained by introducing a rod into a hem present at this end of the fabric. This protuberance provided with its rod is then introduced laterally into the groove provided in the winding support.
  • this groove is of course adapted so that the end of the fabric provided with the rod cannot slide transversely or radially out of the groove.
  • the awning winding mechanism is usually mounted at the ends of the winding cylinder.
  • This mechanism includes among others drive elements, cables, etc ... and is generally contained in a protective box.
  • Document GB-A-155 133 describes a winding support for awning having a longitudinal groove whose cross-sectional shape is essentially rectangular.
  • One introduces there the end of the fabric which consists of a hem provided with a rod.
  • a blocking element is then introduced into the groove and fixed for example using an adhesive therein, so as to prevent the lateral end, which consists of the hem in which a rod is located, from slipping out of said groove.
  • the document CH-A-105 895 describes a system for fixing a fabric of a blind, for example, on its winding shaft.
  • the canvas is fixed using two metal "clipping" elements which are inserted into notches provided for this purpose in the winding shaft.
  • the fabric is first placed on the winding shaft and then the clip-on elements are inserted above the fabric in the notches provided for this purpose. Then the fabric is wrapped normally around the winding shaft.
  • a first drawback lies in the fact that the clip elements fix the fabric to the winding shaft over a small width; therefore, it is not excluded that where the forces are exerted, that is to say near the clip elements, the fabric suffers damage such as tears.
  • the force exerted on the fabric cannot be higher than the bonding force exerted by the clip elements on the winding shaft.
  • the tension exerted on this canvas may be higher than that which holds the clip elements in the notches on the winding shaft. In this case, the clip elements will come out of the notches and the canvas will detach from its winding shaft.
  • the present invention aims to provide a device for fixing a canvas, in particular a canopy, on its winding support which does not have the drawbacks of the prior art.
  • the present invention aims to provide a device which allows mounting and dismounting of the fabric taking place quickly and easily and without having to disassemble the winding mechanisms.
  • the external arm of the blocking element follows the profile of the external surface of the winding support and the internal arm penetrates against the protuberance of the fabric introduced into the housing.
  • the internal arm of the blocking element has lugs or denticles on its contact surface with the wall of the housing.
  • the winding support (1) of a canopy fabric comprises a housing (5) arranged substantially parallel to the axis of the support (1) and into which a protuberance (13) is introduced present at one end of the fabric (11).
  • the protrusion (13) consists of a hem (15) formed over the entire width of the fabric (11) and into which is introduced a rod (17).
  • the protuberance (13) consists of a thick strip of plastic material which is simply fixed or glued over the entire width at one end of the fabric (11) .
  • the housing (5) has an opening (3) over the entire length of the support (1) which is narrower than the housing itself. However, this opening (3) is wide enough to allow the radial passage of the protuberance (13).
  • the rod (17) has a diameter less than the longitudinal opening (3) of the housing (5); therefore, it can be inserted directly into the housing through this opening without having to dismantle the housings containing the canvas winding mechanisms.
  • a blocking element (21) In order to maintain the protuberance (13) in the housing (5), provision is made for a blocking element (21) to be inserted in said housing.
  • the locking element (21) consists of two arms (23, 25), arranged astride one of the lips of the opening (3) of the housing (5).
  • This locking element consists of an outer arm (25) which follows the profile of the outer surface of the support (1) and an inner arm (23) which penetrates against the protuberance (13) in the housing (5) and which is inserted under the fabric (11) which is then rolled up.
  • the housing (5) advantageously has a constriction along the longitudinal opening (3), the simultaneous exit of the protuberance (13) and the locking element (21) is made impossible.
  • the locking element (21) has on the inner arm (23) lugs or denticles (27) on the surface which will come into contact with the wall of the housing (5).
  • pins or denticles (27) are provided so as to prevent the locking element (21) from moving and in particular does not come out of the housing (5).
  • the locking element (21) is preferably in the form of a long longitudinal piece; but it does not have to be the same length as the housing (5) present in the winding support (1). In particular, it is conceivable to fix a fabric (11) having a width of 3 meters using three locking elements (21) each having a length of 1 meter or less.
  • the locking elements (21) with stops which prevent lateral sliding out of the housing (5).
