Definitions

  • the invention relates to a flexible shutter device for closing a bay or any type of opening, comprising drive means for moving the flap between an open position and a closed position; the drive means comprise a drum rotatable about its axis, around which the flap is wound in its open position forming a roller and which the flap can be unrolled to its closed position.
  • the device also comprises slides mounted on a fixed support for guiding along the bay of the portion of the lateral edge of the unwound flap, the flap comprising flexible lateral edges projecting with respect to the plane of the lateral edge of the flap and substantially continuous. moving in the slides.
  • the device according to the invention can for example be used in buildings, or trucks or as cover of pools or boats.
  • Devices for closing a bay having a drum around which a flexible flap is wound in its open position are known.
  • the shutter is unwound by rotating the drum about its axis, so that the shutter goes down by closing the bay while the side edges of this last are guided in two guideways or slides extending parallel to each other.
  • a pushing force is exerted on the lateral edges of the shutter in their longitudinal direction, thereby pushing the lateral edges of the flap to move in the slideways.
  • the progression of the lateral edges of the shutter in the slides can be slowed down (friction due to the wind pressure of up to 160 km / h). These rubs oppose the thrust force exerted on the lateral edges of the flap, by the rotation of the drum. In this case, if the drum continues to be rotated, the flap continues to unfold. In the free space between the roller and the upper edge of the slides; the lateral edges are no longer maintained and risk when there is push on them to form a fold and flambé. The formation of such a fold then prevents any sliding of the flap in the slides. It is necessary to stop the engine and rewind the shutter in order to absorb the fold that has formed. In addition, such a fold can degrade the lateral edges of the shutter.
  • An object of the invention is to overcome these disadvantages by having a shutter device which is closed in a controlled manner by ensuring that the side edges of the flap do not blaze that is to say do not form a fold between the roller and the upper end of the slides as it unfolds.
  • the device according to the invention is characterized in that it comprises containment elements to prevent buckling of the side edges (2,3) in their non-maintained part.
  • the confinement elements comprise a pressure element making it possible to exert a thrust force on the lateral edges of the flap at the non-maintained portion of the flap extending between a first end of the slideways and the roller, so as to obtain a resultant radial thrust force which permanently applies the lateral edges of the flap, in their non-maintained part, on the pressure element.
  • an excess flap is formed between the upper end of the slideways (closest to the drum) and the roller.
  • the pressure element ensures that the non-maintained portion of the flap side edges remains in abutment; this prevents the formation of folds between the roll formed on the drum and the end of the slides closest to the drum.
  • the confinement means comprise a rod extending in the extension of the branches before the slides.
  • the invention is as described in the dependent claims.
  • the present invention relates to a flap device cooperating with drive means, such as a drum whose axis is connected to the shaft of an electric motor.
  • the flap moves in downward and upward movement between, respectively, a closed position and an open position, and is intended for closing a bay in a wall or passage, such as a corridor.
  • any flat element that is at least partially flexible or flexible such as a tarpaulin, a strip made of a plastic material, a wire cloth, a lattice, metal sheet, mosquito net, slatted shutter, hinged flap etc. It is more particularly a shutter that can be wrapped around a drum whose the axis is perpendicular to the direction of movement of the flap during opening of the latter.
  • the shutter device is shown schematically in the closed position.
  • This device comprises a shutter 1 with side edges 2 and 3 protruding from the plane of the shutter 1.
  • the lateral edges 2 and 3 are advantageously formed by a continuous bead 46 (shown in detail in FIGS. Fig. 13 and 14 ) or by a succession of small teeth moving in vertical slides 4 and 5.
  • the slides 4 and 5 are provided on either side of a bay 6 which is present in a wall 7.
  • a drum 8 on which the flap 1 can be wound.
  • an electric motor 9 which drives the drum 8 about its axis 11. This allows to wind the flap 1 on the drum 8 to bring it into the open position or to unroll the shutter 1 to its closed position.
  • the lateral edges 2 and 3 thereof are guided by the slides 4 and 5.
  • a transparent window 10 may be provided in the middle of the shutter 1.
  • the shutter 1 When the shutter 1 is opened, it is wound around the drum 8 by forming a roll consisting of turns formed by successive superimposed layers of the shutter 1.
  • the Figures 3, 4 and 5 show a shutter device according to the prior art.
  • the flap 1 is unwound by rotating the drum 8 about its axis, so that the shutter 1 goes down by closing the bay 6 while the lateral edges 2,3 of the latter are guided in the two slides 4.5 straight s extending parallel to each other.
  • a thrust force is exerted on the lateral edges 2, 3 of the shutter 1 in their longitudinal direction.
  • Each of the slides 4, 5 has a U-shaped section, the central portion 40 is leaned against the structure of the bay 6, the opening of the U of a slide 4 being directed towards the opening of the other slide 5 .
  • Each U-shaped slider 4, 5 has a branch 42 which extends rearwards towards the wall 7, and another branch 44 which extends forwardly towards the drum 8. Fig. 11 and 14 )
  • the drum 8 is held in abutment against the structure of the wall 7 by means of springs 20 directed along a substantially horizontal axis.
  • the figures 3 and 5 present the case when when closing the bay 6, the descent of the shutter 1 along the slides 4,5 is blocked by an obstacle or by friction due to the force of the wind.
  • the drum 8 is always rotated and the flap 1 continues to unwind by creating an excess flap 1 between the roll and the upper end 30 of the slides 4,5.
  • Part of the excess of the flap 1 remains wound on the drum 8 in particular because of the presence of the attachment teeth for holding the turns together; the remainder of the excess forms a fold 15 in the portion of the flap 1 not maintained, that is to say in the space between the roller 8 and the upper end 30 of the slides 4, 5.
  • the fold loop 15 increases.
  • the flap 1 folds in its part not maintained directly at the exit of the slides 4,5; this fold prevents the flap from entering the slides 4.5. We must stop the engine 9 and rewind the flap 1 to absorb the fold 15 that has formed.
  • the Figures 6 to 12 show a flexible shutter device according to a first embodiment of the invention.
  • the slides 4,5 are substantially straight and vertical in most of their height.
  • the upper part of the slides 4,5 is inclined towards the wall 7 with respect to the plane formed by these same slides 4, 5.
  • the slides may have a convex boss 34 to allow them to return in the vertical plane.
  • the rear leg 42 of the slides 4, 5 is extended upwards by a curved flexible guide 33.
  • the set of curvatures 33 and 34 form a flattened "S".
  • the Fig. 9 to 14 show this guide 33 in more detail.
  • the guide 33 has a flattened U-shaped profile. This shape is adapted to the particular shape of the side edge of the flap, which has in the example shown, a protruding bead 46 (illustrated in FIGS. Fig. 13 and 14 ).
  • the guide 33 constitutes a pressure element which makes it possible to exert a thrust force (illustrated by arrows on the Fig. 12 ) at the place where, the winding of the shutter 1, the surface of the part of the flap 1 which is not yet wound comes into contact with the portion of the flap 1 which already forms turns around the drum 8.
  • the guide 33 keeps the adjacent turns one to the other.
  • the guide 33 exerts pressure on these gripping teeth in order to fix the successive turns of the flap to one another when winding the latter around the drum. 8.
  • the guide 33 is held in abutment against the wall 7 by means of a support element 18.
  • the support element 18 is provided at the place where, during the winding of the shutter 1, the surface the part of the shutter 1 which is not yet wound comes into contact with the portion of the shutter 1 which already forms turns around the drum 8. Fig. 6 to 8 )
  • the pressure element 33 makes it possible to exert a thrust force on the lateral edges 2, 3 of the shutter 1 at the non-maintained part of the shutter 1 extending between the upper end 30 of the slides 4.5 and the roller, so as to obtain a resultant radial thrust force which permanently applies the lateral edges of the flap, in the non-maintained part, on the pressure element (33).
  • the end 30 thus makes it possible to guide the flap 1 at the outlet of the slides 4,5 so as to form a curvature 33 in the non-maintained part of the flap 1.
  • the curvature 33 of the flap 1 in its non-maintained part is concave with respect to the drum 8 ( Fig. 12 ).
  • the slides have, in the illustrated manner, a curvature 34 opposite the curvature 33 so as to recover the straight plane of the slides 4,5 in their lower part.
  • the surplus flap 1 which would be formed in its non-maintained portion in case of friction in the slides 4,5 during the unwinding of the flap 1, is "absorbed" by the curvature 33 of the flap 1 in his part not maintained. Indeed, since it is very difficult to reverse a curvature in a flexible flap, it avoids buckling and the formation of a fold (as in the case of Fig. 3 ) in the non-maintained part of the flap edges. This is shown in the figure 12 .
  • the upper end 30 of the slides 4, 5 comes close to the last turn of the flap wound on the drum 8.
  • a space may appear between the upper end 30 of the slides and the last wound coil. In this space the lateral edges 2, 3 of the shutter are not maintained.
  • the Fig. 15 to 23 represent four variants of execution.
  • the drum 8 is no longer movable along a substantially horizontal axis but is held in a fixed manner.
  • the device comprises a movable support structure 50 which keeps the guide 33 in permanent contact with the last turn wound on the drum 8 whatever the open or closed state of the device, that is to say whatever the volume of the roll.
  • the guide 33 mainly provides a sliding effect which limits the friction.
  • the movable support structure 50 can take different forms. To the Fig. 15 to 20 it is a substantially triangular element, pivoting about a pivot axis 52 and whose side 54 facing the drum has a concave curvature with respect to the drum 8.
  • the containment element consists of a substantially straight rod 66 which extends upwardly in the extension of the front branch 44 of each slideway 4,5.
  • This rod 66 preferably extends between the last wound turn of the roll and the portion not yet wound of the flap (1), close to the lateral edge 2,3, just in front of the bead 46 ( Fig. 23 ).
  • the rear branch of each slideway 4,5 is also extended upwards by a guide 60 substantially straight.
  • a reinforcement U 68 may be provided around the guide 60 and the rod 66.
  • a return system comprising springs 62 and return pulleys 64 keeps the guide 60 bearing against the roller.
  • the rod 66 may extend to a height corresponding to the point of contact between the roll and the guide 60.
  • the device has been described in a position where the flap moves in a vertical plane and in a direction from top to bottom (when closing).
  • the position of the flap and the drum is not limiting.
  • the same device can be used in other positions, in particular, the flap can be vertical but open in a lateral direction.
  • the device according to the invention can be used in a horizontal position, for example for the cover of boats or swimming pools.
  • the upper end of the slides must be understood as the end closest to the drum; but for the sake of clarity of the disclosure with respect to Figs., it is called the upper end in the present description.
