Definitions

  • the invention relates to a device for winding or unwinding a canvas such as a flexible blind, a awning, a swimming pool cover, a tarpaulin truck or any other similar item of textile structure or equivalent.
  • the fabrics used as tarpaulins or the like are intended for be wound on a pivoting mechanism generally mounted in a chassis. Gold, it is frequently observed, in particular with regard to very large fabrics, the appearance of folds which increase as the winding progresses.
  • the document EP 0 091 278 describes a device for closing a window with a roll-down curtain according to the preamble of claim 1.
  • the edges of the curtain are laterally guided in grooves associated with the window frame. These gorges receive a needle which extends over the entire length of the window, and which penetrate inside a scabbard at the edge of the canvas, as the latter is held.
  • a problem which the invention therefore proposes to solve is that of the winding of a canvas around an axis without the appearance of folds on the surface of it.
  • a second problem is that of limiting or eliminating the excess thicknesses which are born when the canvas is rolled up.
  • the invention therefore relates to a device for winding and unwinding a fabric. of the blind, awning, pool cover type, etc., around a pivoting winding axis relative to a frame, said fabric having a constant width between these two side edges.
  • This device is characterized in that the fabric has on each lateral edge a sheath, and in that it comprises two cores threaded each in one of the sheaths, and means for maintaining the constant spacing between these two cores.
  • the invention consists in equipping the canvas with lateral sleeves and in prohibit the bringing together of these sleeves and therefore the edges of the canvas.
  • the slight transverse tension to which the fabric is subjected thus avoids the floating of this one and the birth of folds.
  • the side sleeves do not cause almost no extra thickness, which limits the volume of the chassis and as a consequence to increase the length of canvas usable with the same winding system.
  • the means for keeping the spacing constant between the two cores are arranged near the winding axis. We reduce thus at a minimum the distance between these means and the axis, on which could possibly appear folds.
  • the sheath can consist of a folded strip of fabric, the edges folded over each other are fixed to each edge of the fabric, by sewing, by ultrasonic welding or heat welding.
  • the inner face of the sheath has a low coefficient of friction, especially with regard to the nucleus it receives. This does not increase the torque required to wind the canvas and avoid blockages.
  • this sheath can for example be made of a fabric chosen from the group including polyester, polyamide, glass textiles coated with polytetrafluoroethylene.
  • the housing and the core have complementary shapes, which allow sliding guidance of the core in the body and more precisely the housing, as well as the precise positioning of the scabbard.
  • the housing and the core are cylindrical.
  • the core partially extends beyond the housing.
  • the means intended to prohibit the sliding of the core in the housing are removable from the body. This allows solve the problem of introducing the core into the housing, then maintaining it in position during actual operation. So in one form of execution practical, these means consist of two axes capable of sliding in the body, arranged on either side of the core and the opposite faces of which enclose this core at a necking provided for this purpose therein.
  • the means intended to prevent sliding of the core consist of at least one magnetic element placed on the body and / or on the nucleus.
  • the body characteristic of the invention comprises a fixing plate.
  • the invention relates to winding-unwinding devices fabrics intended to cover different types of surface. So it can be canvas serving as a banner deployed for example on a terrace to provide shade, or many more blinds, that is to say canvases unrolled on a glazed surface for par example protect from the sun's rays. It can also be protective fabrics serving as a tarpaulin, for example on a truck, or as canvases protection and pool cover. Generally speaking, this is canvas integrated into textile structures.
  • the fabric (1) is mounted about an axis (3) pivoting in a frame (2).
  • the fabric (1) has sheaths on its edges (4, 5) and concomitantly the chassis (2) has characteristic means (13) allowing the spacing between the selvedges (4, 5) to be kept constant.
  • each of these selvedges (4, 5) receives a piece of fabric (10) folded back on itself to form a continuous sheath parallel to the selvedge (5).
  • the edges (8, 9) of this fabric (10) are connected with the edge (4, 5) of the fabric (1).
  • the strip (10) intended to form the sheath is made of a flexible material for be able to be rolled up flat, thin so as not to cause excess thickness and be able to be easily deformable in the body of the characteristic means of the invention. he also important that it is very abrasion resistant and therefore has a low rate friction with materials used for the organs with which it must cooperate.
  • this strip can for example be made from a glass textile coated with polytetrafluoroethylene, or polyester or polyamide.
  • the invention consists in introducing inside this sheath (6, 7) a core (12) able to cooperate with a body (13) integral with the chassis (2).
  • a core (12) able to cooperate with a body (13) integral with the chassis (2).
  • the invention is not limited of course not to the embodiment illustrated in Figures 2 to 6 but to contrary embraces all the variants in which the principle of the invention is respected, i.e. in which a core is threaded into the sheath and is found held by a body secured to the chassis, not by direct mechanical contact but with the interposition of the strip (10) forming the sheath (6).
  • the body (13) is breaks down into two main parts, namely a part (14) which ensures the maintenance of the core, in the transverse direction of the fabric, and a part (15) whose function is to block the sliding of the same core in the longitudinal direction of the unwinding of the Web.
  • the part (14) proper has on its face opposite the canvas, a longitudinal housing (16) extending over the entire length of the part (14).
  • This housing (16) has an opening (17) whose two edges (18, 19) are parallel between them and to the longitudinal axis of the housing (16).
  • this housing is able to receive a core (12).
  • this core (12) Different forms can be adopted for this core (12), it being understood that it is preferable for it to be of cross section constant, and it is necessary that its thinner section is less at the distance between the edges (18, 19) of the opening (17), and this so that this core (12) is retained and cannot move in the transverse direction of the fabric.
  • this core (12), and the housing complementary (16) are both cylindrical, but the invention also covers different shape variants, as illustrated in particular in FIG. 8 in which the nucleus is ovoid, or even variants in which the housing has dimensions larger than the core, and a different shape, while presenting an opening preventing the exit of the nucleus.
  • the ends (32, 33) of the cylinder (12) are in the form of hemisphere to allow the cylinder (12) to slide in the sleeve (6) without damage it.
  • the hemispherical shape can be replaced by any other soft shape connecting to the body of the core (12) without sharp edge.
  • the core (12) can be totally or partially nested in the body in the transverse direction of the canvas.
  • the complementary forms of the housing (16) and the core (12) allow this last to move by sliding in the longitudinal direction of the canvas, and this during the phase of fitting the sheath inside the housing (16).
  • the part (15) of the body (13) is intended to prevent the displacement of this core (12) in the longitudinal direction.
  • this part (15) receives two axes (25, 26), capable of sliding in the transverse direction of the fabric, that is to say perpendicular to the direction of sliding of the core (12) in the housing (16).
  • axes (25, 26) are arranged so as to penetrate the volume corresponding to the passage of the core (12). Additionally, the core (12) has two lateral recesses (27, 28) inside which can slide freely the axes (25, 26). When these axes (25, 26) are in position in the constricted (27, 28), the sliding of the core (12) along the longitudinal axis is impossible. However, as illustrated in Figure 6, the space between the axes (25, 26) and the constrictions (27, 28) allow the passage of the fabric forming the sheath and therefore the scrolling thereof in the body (13).
  • the sliding of the core (12) is not blocked not mechanically but thanks to magnetic means.
  • the body (13) may include a magnetic part (30) forming a magnet and able to attract another magnetized, or simply ferro-magnetic, zone of the core (12).
  • the means (10) characteristic of the invention are arranged as close as possible to the winding axis (3), that is to say for example that they are fixed on the chassis.
  • the body (13) has a plate (40) allowing its attachment to different types of chassis.
  • the cores (12) When the fabric is placed in the frame (2), the cores (12) are introduced into the sleeves (6), then placed inside the housing (16) of the body (13), the axes (25, 26) being retracted. When the core (12) is in place, the axes (25, 26) are extracted to come opposite the necks (27, 28) of the core (12) (see Figure 6).
  • the cores (12) and the sleeves (6) are maintained at a constant spacing, which ensures transverse tensioning, and therefore limits as much as possible the risk of wrinkles appearing on the winding.
  • the winding-unwinding device of a canvas according to the invention has the notable advantage of preventing the formation of folds on a canvas at the time of its winding. It therefore follows that the invention authorizes the installation of very large fabrics, which was not possible with previously existing solutions.
