Definitions

  • the present invention relates to a roll-up fabric protection system.
  • the canvas is rolled up in a chest, for example fixed to a wall.
  • a first type of mechanism uses articulated arms.
  • a second type of mechanism uses two guide bars each carrying a rail, and a load bar intended to slide along the two rails to pull the canvas and unroll it from the box.
  • a system of pull links associated with a motor makes it possible to control the movement of the load bar along the two rails.
  • Each pulling link is wound on a drum operable by the motor and extends inside respectively the first guide bar and the second guide bar.
  • the two pulling links each pass respectively through a first deflection pulley, called fixed, located at the end of the guide bar.
  • the two pulling links then meet inside the load bar, each via a deflection pulley, called mobile, secured to the load bar.
  • a device for tensioning the two links for example housed in the load bar, the tension of which is adjustable, ensures the junction between the two links and makes it possible to keep the canvas taut during its movement. This mechanism is well described in patent applications FR2692930A1 and FR2546869A1 .
  • the object of the invention is therefore to propose a protection system using a roll-up fabric whose architecture makes it possible to provide solutions to the two points raised above.
  • the movable deflection pulley comprises an axis of rotation located in a plane, called rolling plane, in which each guide roller is caused to roll.
  • the load bar comprises a device for holding the fabric, having a support surface arranged in the extension of said support surface and comprising means for fixing the fabric against said support surface for keep it in the guide plane.
  • the load bar also comprises a zone for attaching the second edge of the canvas, said attachment zone being arranged to receive the second edge of the canvas along an axis present in a plane parallel to the guide plane and lower than said guide plane.
  • each guide bar is made in the form of a section.
  • the profile of the guide bar has a cross section provided with a guide path to accommodate the guide rollers of the load bar, forming a guide rail.
  • the profile of the guide bar has a cross section provided with a housing in which is inserted a profile for guiding the canvas.
  • the profile of the guide bar has a cross section provided with a housing intended to receive the pull link.
  • the profile of the guide bar has a cross section provided with a housing for fixing the guide bar to the trunk.
  • the profile of the guide bar has a cross section provided with a housing in which a light device is inserted.
  • the profile of the guide bar has a cross section provided with a housing for fixing the guide bar to the post and/or to a reinforcement bar.
  • the profile of the guide bar has a cross section provided with a housing for draining rainwater.
  • the load bar comprises, over its entire length, a channel overflowing at each end into the housing for draining rainwater from each guide bar.
  • the second edge of the canvas has a hem in which is inserted a bead configured to cooperate with a housing forming said fastening zone of the load bar.
  • the invention is related to the field of roll-up canvas protection systems against the sun or bad weather, of the pergola or equivalent type.
  • this type of system uses a fabric 1 wrapped around a drum 10 operable in rotation around its axis.
  • the actuation can be implemented using an 8 motor.
  • the fabric 1 is advantageously rectangular in shape and is intended to be unrolled or rolled up on the drum, in a so-called longitudinal direction.
  • the drum 10 is housed in a box 2 fixed in height, for example to a wall M, parallel to the ground. It is arranged in a direction transverse to the direction of movement of fabric 1.
  • the fabric 1 has two opposite transverse edges, called first transverse edge and second transverse edge, and two opposite longitudinal edges, called first longitudinal edge and second longitudinal edge.
  • a canvas guide frame 1 is fixed to said trunk (via the drum).
  • This frame can have a U-shape comprising two guide bars 3a, 3b (reference 3 generally) parallel to each other and possibly a bar or crosspiece, called reinforcement 4 acting as reinforcement between the two guide bars 3a, 3b .
  • the reinforcement bar may not be present or the system may have one or more bars of this type, fixed in one or more places between the two guide bars 3.
  • the first transverse edge of the fabric is fixed to the drum and the second transverse edge of the fabric is fixed to a load bar 5 of the system.
  • the load bar 5 is intended to slide at each end along the two parallel guide bars 3, in the longitudinal direction.
  • the fabric 1 is caused to slide on the guide bars along its two longitudinal edges.
  • the system also comprises at least two posts 6 for supporting the frame, each of the two posts supporting a guide bar at its end opposite that fixed to the trunk 2. These two posts can be fixed at the end of the guide bar 3 or so offset from the end of the guide bars. These two posts 6 can be height-adjustable to adjust the inclination of the plane formed by the fabric 1, each guide bar 3 being able to be pivotally mounted on its respective post 6 to allow the height adjustment and the inclination of the trunk.
  • a pivoting mechanism can also be provided at the level of the trunk 2 to allow the tilting of the frame.
  • the two guide bars 3 are identical and extend symmetrically with respect to a vertical plane perpendicular to the ground.
  • the system comprises a mechanism for moving the fabric 1 to roll it up or unroll it.
  • This mechanism comprises two parallel pull links 7, each formed for example of a strap or a cable.
  • Each pull link 7 is wound on the drum 10 in the opposite direction to the fabric 1 and extends along a separate guide bar 3.
  • Each pulling link 7 passes over a fixed return pulley 70 located at the end of the guide bar 3, to return in the direction of the drum 10. Then the end part of each of these pulling links 7 passes over a return, called mobile return pulley 71, fixed to the load bar 5, so as to be deflected at approximately 90° along the axis of the load bar 5.
  • the two end parts of the pulling links are then connected together on the inside of the load bar.
  • the system may include a tensioning device. This device can comprise for example an adjustable tension spring housed in the load bar 5, ensuring the junction between the two pulling links and/or two springs 72 (as on the figure 2 ) integrated into each pull link 7 and each arranged in a separate guide bar 3.
  • the tensioning device makes it possible to maintain the fabric 1 in permanent tension, whatever its position along the two guide bars 3a, 3b.
  • the fabric 1 is for example wound on the drum 10 in the clockwise direction while the draw ties 7 are wound on the drum in the anti-clockwise direction.
  • This rotational movement causes a progressive winding of the two pulling links 7.
  • the traction exerted on the pulling links 7 is transmitted by the fixed 70 and mobile 71 return pulleys to the load bar 5, which is thus subjected to a longitudinal force, allowing its translation along the two guide bars 3.
  • the drum is rotated in the direction of clockwise.
  • the tensioning device makes it possible to maintain an appropriate tension on each pulling link during this operation.
  • Each pull link 7 is advantageously formed of a strap. It can also be a cable, rope or equivalent.
  • the two guide bars 3 are arranged in parallel so as to define between their two rails a guide plane P of the fabric 1, in which the fabric 1 is caused to move when it is unrolled or rolled up.
  • the load bar 5 comprises at each end two guide rollers 50, arranged to cooperate with the guide rail 36 of the guide bar 3.
  • the load bar 5 also comprises at each of its ends the movable return pulley 71 defined above.
  • the movable return pulley 71 is positioned between the two guide rollers 50.
  • the two guide rollers 50 are made to roll on the corresponding guide rail 36 of the guide bar 3, following a plane, called rolling plane P2, which is perpendicular to their axis of rotation and which corresponds to the plane in which each roller is brought into contact with the guide rail and to roll on the guide rail 36.
  • This rolling plane P2 is also perpendicular to the guide plane P.
  • the two guide rollers 50 each have an axis of rotation A1, A2 positioned in said guide plane P.
  • the axis A3 of the mobile deflection pulley 71 (corresponding to its axis of rotation) is located between the axis of rotation A1 of the first guide roller and the axis of rotation A2 of the second guide roller 50.
  • the axis A3 of the deflection pulley mobile 71 is also advantageously included in the pla bearing P2 of the two guide rollers 50.
  • the movable return pulley 71 has an axis perpendicular to the guide plane P to return the pulling link 7, coming from the fixed return pulley 70 located at the end of the guide bar 3 , at an angle of approximately 90°, to direct it along the axis of the load bar 5.
  • guide P. Its axis A3 is thus oriented perpendicular to the guide plane.
  • the fabric 1 is fixed by its second transverse edge to the load bar 5.
  • This second transverse edge may comprise a hem in which is inserted a rod 11, forming a transverse bead.
  • the fixing of the edge is carried out by housing the bead thus formed in a transverse housing 51 advantageously made over the entire length of the load bar 5.
  • this transverse housing 51 extends along an axis X situated outside the guide plane P of the fabric, more particularly under this guide plane P, so as to shift the attachment point.
  • the load bar 5 in order to place the canvas 1 in the guide plane P, carries at each end a holding device arranged upstream with respect to its attachment point and in a plane higher than that including the attachment point.
  • This holding device may comprise a flange 52 defining a plane against which the fabric bears, this plane being located in said guide plane.
  • the load bar 5 Over all or part of its length, the load bar 5 also comprises an advantageously flat bearing surface 54, extending between the two flanges, and forming a bearing plane for the fabric 1, this bearing surface being located in the extension of the guide plane P.
  • the maintenance of the canvas 1 on the flange 52 can be achieved by using screws.
  • the fabric 1 is clamped on the load bar 5 along a plane aligned with the guide plane P, it comes to rest on the bearing surface 54 and it is attached to the load bar 5 by its second transverse edge, at a point of attachment located under the guide plane P.
  • the fabric 1 has an inclined termination, allowing it to avoid the formation of an obstacle to the water flow to a channel 53 arranged over the entire length of the load bar.
  • This channel 53 is intended to open at each end of the load bar 5 into the housing 35 dedicated to the flow of water made in each guide bar 3. At each end the channel 53 projects outwards to overflow sufficiently inside the housing 35 for draining the water from the corresponding guide bar 3.
  • each guide bar 3 also comprises a longitudinal housing 30 in which is inserted a fabric guide profile 1.
  • This housing 30 is juxtaposed to the guide rail 36.
  • This fabric guide profile 1 can have a cross section comprising a guide clamp cooperating with the corresponding longitudinal edge of the fabric 1 so that the latter slides along the guide bar 3.
  • the clamp is positioned to guide the fabric 1 along said plane of guide P.
  • This guide clamp is surmounted by two antennae acting as a spring to allow permanent adjustment of the tension of the fabric.
  • Each guide bar 3 comprises a longitudinal housing 31 in which is stretched the pulling link 7, for example formed of a strap.
  • This housing 31 can be juxtaposed with the housing 30 dedicated to receiving the fabric guide section.
  • the housing 35 for draining water can be located under the guide rail 36. As indicated above, it has an opening along its entire length allowing the channel 56 of the load bar to communicate with this housing 35 to pour the collected rainwater onto the canvas, regardless of the position of the load bar/canvas couple along the guide bars 3.
  • the guide bar 3 has a dedicated housing 34 to be fixed to the post 6 and/or to the reinforcement bar 4 (if present). Juxtaposed to this housing 34, the guide bar 3 advantageously includes a housing 33 to accommodate a light device. This luminous device may comprise a strip of light-emitting diodes. Above this housing, the guide bar 3 may include a housing 32 for fixing the guide bar to the trunk.
