- the present invention relates to a shutter device cooperating with drive means, such as a drum whose axis is connected to the shaft of an electric motor.
- the shutter moves in a 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 planar element at least partially flexible or flexible such as than a tarpaulin, a strip of plastic, a wire mesh, a mesh, a metal sheet, a mosquito net, etc. It is more particularly a shutter which can be wound around a drum whose axis is pe ⁇ endicular to the direction of movement of the shutter when the latter is opened. It should, however, be noted that a pronounced preference is given to flexible shutters formed, for example, by a tarpaulin. The attached figures therefore relate more particularly to such a tarpaulin.
- the shutter device is shown schematically in the closed position.
- This device comprises a flap 1 with lateral edges 2 and 3 projecting from the plane of flap 1 which are advantageously formed by a continuous bead or by a succession of small blocks articulated relative to each other moving in guide paths 4 and 5.
- Guide paths 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 shutter 1 can be wound.
- an electric motor 9 which makes it possible to drive the drum 8 around its axis. This makes it possible to wind the shutter 1 on the drum 8 to bring it into the open position or to unwind the shutter 1 towards its closed position.
- the lateral edges 2 and 3 of the latter are guided by the guide tracks 4 and 5.
- a transparent window 10 In the middle of the shutter 1 is provided a transparent window 10.
- the shutter 1 When the shutter 1 is opened, the latter is wound around the drum 8 by forming a roll consisting of turns formed by successive supe ⁇ osed layers of the shutter 1.
- means of containment are provided, making it possible to obtain a very compact roller in which the successive turns are clamped one against the other.
- the confinement means thus make it possible to prevent the turns of the roller from forming gathers during the unfolding of the flap 1 when its edges engage in the upper end of the guide tracks 4 and 5.
- the confinement means comprise, in particular, attachment means, which extend along the length of the flap 1 on at least one of the faces of the latter. When the shutter 1 is wound around the drum 8, these means of attachment make it possible to fix the successive turns of the latter, one to the other in order to prevent the successive layers of the shutter 1 from sliding relative to one another.
- a first embodiment of the invention is shown schematically in Figures 3 and 4. These figures show part of the flap 1 at the location of one of the side edges 2 or 3 which are formed by a continuous bead.
- the shutter 1 has, in particular, near the lateral edges 2 and 3, hooking means 11 which comprise projections 12 extending along the length of the shutter 1 on one of the faces of the latter. During the winding of the shutter 1, these projections grip in corresponding recesses 13 provided on the other face of the shutter 1. In this way, the successive turns of the shutter 1 which is wound around the drum 8 are fixed to the one in relation to the other.
- the projections 12 By the presence of a certain friction or a certain adhesion between the projections 12 and the corresponding recesses 13, the different layers of the flap 1, which form these turns, cannot slide relative to one another.
- the projections 12 are, in particular, clamped in the corresponding recesses 13 in order to fix the successive turns to one another.
- the area of the flap 1, which is provided with said projections 12 and the corresponding recesses 13, is made of an elastomeric material, such as for example polyurethane.
- an elastomeric material increases the attachment of the projections 12 in the recesses 13.
- FIGS 5 and 6 show a second embodiment of the shutter 1 according to the invention, in which the attachment means 11 comprise a strip 14 provided with hooks.
- a ribbon 14 is, for example, formed by the hooks of the Nelcro® type which is fixed to the two faces of the flap 1 in such a way that, when the flap 1 is wound around the drum 8, the hooks of the ribbon 14 of one of the faces of the shutter grips with the hooks of the ribbon 14 which is provided on the other face of the shutter.
- the ribbons extend in the longitudinal direction of the flap 1 near each of the side edges 2 and 3 of the latter.
- the ribbons 14 are preferably substantially continuous, it is also possible that an interrupted succession of ribbons in the longitudinal direction of the flap 1 is provided.
- FIGS 7 to 9 show a third embodiment of the attachment means according to the invention, in which a toothed belt 15 is fixed to the flap 1 and extends in the longitudinal direction of the latter.
- a toothed belt 15 is fixed to the flap 1 and extends in the longitudinal direction of the latter.
- one of the sides of the shutter 1 is provided with a succession of teeth 16, while the other side of the shutter 1 has corresponding notches 17.
- the teeth 16 of a side of the latter grip with the notches 17 on the other side of the flap 1 preventing the sliding of the successive layers of the flap 1 in the roll thus formed.
- the shutter 1 is provided with a succession of teeth along the lateral edges of the shutter on only one face of the latter.
- the other face then has a continuous band of an elastically compressible material, such as for example an artificial foam, so that, during the winding of the shutter, the teeth compress this band locally by forming hollows in which the teeth s 'grip. In this way, the successive turns of the rolled shutter cannot slide relative to each other.
- FIG. 10 shows a cross section of the successive layers of a shutter 1 which is wound around a drum 8, according to a fourth embodiment of the attachment means according to the invention.
- the hooking means comprise a projection 12 which is fixed to the flap 1 and which extends in the longitudinal direction of the flap 1 near its lateral edge 2 or 3.
- the projection 12 extends from 'one side of the shutter 1, in particular, parallel to the lateral edges 2 and 3 of the shutter 1 and cooperates with a branch 18 which is delimited by two ribs 19 and 20 of circular section which are provided on the other side of the shutter 1 and which also extend in the longitudinal direction of the flap 1 and parallel to the lateral edges 2 and 3.
- the section of the base of the projection 12 near the surface of the flap 1 is smaller than the section of the upper part, so that this projection 12 can be clamped in the groove 18 between the ribs 19 and 20 during the winding flap 1. To this end, the ribs 19 and 20 can deform elastically when the projection 12 is introduced into the groove 18.
- the projection 12 is gradually sandwiched in the groove 18 between the ribs 19 and 20.
- these ribs 19 and 20 approach each other with respect to their base 48 and the upper part of the projection 12 widens and is slightly flattened while the curvature of the flap 1 increases. In this way, the projection 12 is wedged between the ribs 19 and 20 in the groove 18, thereby fixing the successive turns of the flap 1 to one another.
- the shutter 1 When the shutter 1 is moved to its closed position, the shutter 1 gradually elongates at the place where it is unwound from the drum 8. At this location, the ribs 19 and 20 and the projection 12 resume their original shape, so that the projection 12 can be released from the ribs 19 and 20.
- the lateral edges 2 and 3 form part of a continuous strip 49 extending along the flap 1 also having the ribs 19 and 20 and the projection 12.
- This strip 49 is preferably made of an elastomeric material, such as for example polyurethane.
- To each of the lateral sides of a flexible cover 50 is fixed such a strip 49 in order to constitute the shutter 1.
- the projection 12 is preferably provided with a succession of notches 51 extending transversely relative to its longitudinal direction. These notches 51 are spaced at a regular distance and prevent cracks from forming in this projection 51 during the winding of the flap 1.
- This projection 51 is preferably provided on the face of the flap 1 which corresponds to the face outside of the turns formed when the shutter 1 is wound.
- pointed rods 52 extending transversely relative to the plane of the flap 1 are present in the projection 12. These rods 52 extend with their point in the groove 18 so that, when the projection 12 is engaged in this groove 18 when the flap 1 is wound, the rods 52 penetrate into the upper part of the projection 12 of the preceding turn. In this way, the successive turns of the rolled up shutter 1 are firmly hooked to one another and cannot slide relative to one another. This makes it possible to unwind the shutter 1 from its open position by exerting a pushing force on the lateral edges 2 and 3 of the shutter 1 in their longitudinal direction in the guide tracks 4 and 5 to move the shutter 1 to its closed position. In this embodiment of the invention, the shutter 1 can be very large.
- FIG. 13 shows a fifth embodiment of the attachment means, according to the invention. This figure shows a cross section of part of the successive layers of the shutter 1 formed during the winding of the latter around the drum 8.
- the shutter 1 has, near the lateral edges 2 and 3, a W-shaped section thus defining on one side of the shutter 1 three ribs 21, 22 and 23 extending parallel to each other in the direction longitudinal of the flap 1. Between these ribs 21, 22 and 23 are formed grooves 24 and 25. The other side of the flap
- rib 1 has two ribs 26 and 27 which correspond to the branches 24 and 25. Between these latter ribs 26 and 27 extends a groove 28.
- Teeth 29 are provided at the place where the ribs 21, 22 and 23 and the grooves 24 and 25 on one side of the flap 1 are in contact with, respectively, the groove 28 and the ribs 26 and 27 of the other side of the flap 1, while the latter is rolled up.
- the teeth 29 on one side of the flap 1 grip with the teeth 29 on the other side of the flap 1.
- These teeth 29 form, in particular, a barbed area in said grooves and on said ribs.
- the location of the flap 1 having the W-shaped section is preferably made of an elastomeric material, such as for example polyurethane, which is rigid enough to be able to hold said ribs in the corresponding grooves.
- a pressure element is provided which makes it possible to exert a pushing force on the hooking means in order to fix the successive turns of the flap to each other, during the winding of the latter around the drum 8. This is shown diagrammatically in FIGS. 14 to 16.
- the shutter 1 is clamped between the part of the shutter 1 which is already wound on this drum 8, constituting a roller 31, and the pressure element.
- This pressure element comprises, in particular, a rotary cylinder 30 whose axis is substantially parallel to the axis of the drum 8.
- This cylinder 30 is provided at the place where, during the winding of the shutter 1, the surface of the part of the shutter 1 which is not yet wound comes into contact with the part of the shutter 1 which already forms turns around the drum 8. Consequently, also at this location, the turns of the roller 31 take place and the means hooking come off during the shutter 1 towards its closed position.
- the compressor element 30 and the drum 8 are mounted movably relative to each other.
- means are provided for maintaining a pressure force between the roller 31 and the pressure cylinder 30.
- the rotary pressure cylinder 30 is fixedly mounted to the wall 7 above the bay 6, while the shaft 32 of the drum 8 can move in a horizontal direction in a horizontal slide 33 provided in a housing 46 of the device at each end of the shaft 32.
- FIG. 16 schematically represents the pressure cylinder 30 when the shutter 1 is provided with attachment means similar to those represented in FIG. 13.
- the attachment means 11 must be such that the supe ⁇ osed turns of a flap 1 wound on a drum 8 are fixed to one another, but that these turns are detached automatically as and when one of the other when the drum 8 is rotated in the opposite direction to that for winding the shutter 1 on the drum 8.
- Figures 17 to 19 show a particular embodiment of the device according to the invention, in which the confinement means comprise a belt 36 which at least partially surrounds the roller 31 formed by the flap wound on the drum 8.
- This belt 36 exerts a compressive force on the roller 31 during the winding or during the unwinding of the flap 1 and has means for continuously adapting the shape of the belt 36 to the diameter of the roller

- a tensile force is exerted on the other end of the belt 36.
- a weight 47 is fixed to this other end which can move vertically along the guide tracks 2 and 3.
- FIGS. 20 and 21 show, in a very schematic manner, another advantageous embodiment of the device according to the invention, in which a belt 40 closed on itself cooperates with the roller 31.
- This closed belt 40 is guided on cylinders 41 which are located around the roller 31 at a certain distance from the latter.
- the axis of these cylinders extends substantially parallel to the axis of the drum 8.
- the outer surface of the belt 40 surrounds the roller 31, preferably near the side edges 2 and 3, and encloses the roller 31 by exerting a pressure force on it.
- a free space 42 is provided through which the flap 1 can move towards the guide tracks 4 and 5 during its unwinding.
- the belt 40 which is in contact with the outer turn of the roller 31, is driven by the latter by moving on the cylinders 41.
- the belt 40 can be made of an elastic material, such as for example rubber, so that it can lengthen when the diameter of the roller 31 increases during the winding of the shutter 1, or can be shortened when this diameter decreases during the course of the shutter 1.
- one of the cylinders 41, on which the belt 40 is guided can be mounted in a movable manner and is, for example, connected to a spring thereby ensuring that the strap 40 is still tense.
- this movable cylinder is moved as the diameter of the roller changes during the winding or unwinding of the flap 1.
- the cylinder 41 which is located closest to the roller 31, in the space between the latter and the part of the flap 1 not wound, can also be movable in order to maintain this cylinder near the roller 31 or in abutment against it. latest.

- a pressure cylinder 30 is provided at the place where the unwound shutter is transformed into a roller 31 consisting of successive turns during the winding of the shutter 1.
- This cylinder 30 exerts a pushing force on the shutter at the location of the suction cups 53 in order to adhere the latter to the outer face of the turn 1 flap which has just formed.
- the shutter device according to the invention may comprise a shutter which consists of a succession of rigid strips 54 which are articulated with respect to each other. Such a shutter device is shown diagrammatically in FIGS. 24 and 25. To move the shutter 1 to its open position, the latter is wound around a drum 8.

- This pressure element 57 comprises two cylinders 58 and 59 which can rotate freely about their axis 60 which is parallel to the axis of the drum 8.
- a belt 61 closed on itself is guided on the cylinders 58 and 59 by pressing on a part of the periphery of the roller 31.
- Said cylinders 58 and 59 are situated at a certain distance from each other so that the belt 61 which is guided around the cylinders 58 and 59 bears against the roller 31.
- the shaft 32 of the drum 8 moves in a slide 33 extending in a direction pe ⁇ endicular to the plane of the part of the flap not wound when opening or closing the shutter 1.
- a spring not shown in FIG. 24, is provided which exerts a pressing force on the shaft 32 or on the cylinders 58 and 59 and which makes it possible to maintain a pressing force between the roller 31 and the belt 61.
- FIG. 26 represents a drum 8 on which is wound a shutter 1 formed by a flexible cover 50 having lateral edges 2 and 3 which project relative to the plane of the shutter 1 next to the latter which is directed towards the drum 8.
- the drum 8 comprises a cylinder 62, the ends 63 of which are flared, thus having an essentially conical shape. These conical ends 63 are provided with a notch 64 extending in a spiral around their outer surface.
- the shutter 1 is preferably trapezoidal in shape so that the width of the shutter 1 at the location of the lower edge 65 thereof is greater than the width of the upper part of the shutter 1. Thus the distance between the paths of guide 4 and 5 gradually increases from the upper end of the guide paths 4 and 5 near the drum 8 to the lower end of these guide paths 4 and 5.
- FIG. 27 represents a variant of this latter embodiment in which the successive turns of the shutter 1, wound around the drum 8, are fixed to one another during the winding of the shutter 1.
- the edges side 2 and 3 of the shutter 1 have a rib 66 extending transversely relative to the plane of the shutter 1.
- This rib is provided with a notch 67 and 68 at each of the lateral faces of the rib 66.
- this rib 66 extends beyond the previous turn of the shutter 1 and grips in the notch 67 of the rib of this previous turn. In this way, the successive turns of the shutter 1 are fixed to one another during the winding of the shutter 1.
- a pressure element 57 is provided which is formed by a cylinder whose axis is preferably parallel to the axis of the drum 8. This cylinder resting on the side edge 2 or 3 of the part of the flap 1 which turns into a turn so as to insert the rib 66 in the notch 67 of the previous turn.
- Figures 28 to 32 show yet another embodiment of the invention in which an oblong member 69 is provided extending along the lateral edge 2 or 3 of the flap 1.
- This member 69 is incompressible in its longitudinal direction is s 'presses on a projecting part 70 provided at the lateral edge 2 or 3 of the flap l.
- this member 69 is wound together with the flap 1 by forming successive turns as shown in FIGS. 30 and 32
- a pushing force is exerted on this member 69 in its longitudinal direction.
- the lower end of the member 69 acts on said protruding part 70 located near the lower edge 65 of the shutter 1.
- the member 69 can be driven by the shaft 32 of the drum 8 or directly, for example, by an electric motor.
- the incompressible member 69 When the shutter 1 is in the open position, the incompressible member 69 is wound around the drum 8 by forming supe ⁇ osed turns.
- the member 69 is provided with attachment means for fixing the successive turns to one another so that, during the unfolding of the shutter 1, for example, by the drive of the drum 8, a pushing force is exerted on the incompressible member 69 in its longitudinal direction.
- the attachment means comprise, in particular a succession of teeth 71 provided on one face of the member 69, while corresponding notches 72 are provided on the opposite face of this member 69. In this way, during winding of the shutter 1, the successive turns formed by the member 69 grip one inside the other when the teeth 71 engage in the notches 72.
- the incompressible member 69 is also moved in these guide paths when the flap 1 is opened or closed.
- the flap 1 has a thickening 73 extending along the length of the flap 1, the thickness of which in a direction pe ⁇ endicular to the plane of the flap 1 essentially corresponds to the thickness of the incompressible member 69 in this direction.
- the incompressible member 69 may consist of a rod of flexible material such as, for example, polyurethane reinforced with glass fibers, or may be formed of a Kevlar rod. It is also possible to use a metal or synthetic chain, the links of which are provided with means for gripping one another when the chain is wound.
- a pressure cylinder 30 is provided at the place where the member 69 is wound to form said turns when the shutter 1 is opened. This cylinder 30 exerts a pressure force on the member 69 in order to engage the teeth 71 of the turn which forms in the notches 72 of the previous turn.
- the attachment means may for example comprise a succession of permanent magnets which extend in the longitudinal direction of the flap to one side of the latter.
- the confinement means and the attachment means are located at or near the side edges 2 and 3 of the flap 1, it is also possible that these means are provided, for example, substantially in the middle between the side edges 2 and 3 or that they extend over the entire width of the shutter 1.
- the shutter device according to the invention, is not limited to doors with vertical guideways, but may also have horizontal guideways or extending in any direction, when the shutter is, for example, used as sunscreen. In still other cases, it is possible to provide only a horizontal guide path at the upper side of a bay, so that the flap is suspended from this guide path or to provide no guide path.
- the ribs can be constituted by a succession of projections extending at a certain distance from each other.
