Definitions

  • the present invention relates to a coupling device for roller shutter, intended to ensure the connection between the deck and the winding shaft of the shutter. It will find its application in the technical field of shutters, both manufacturers and installers.
  • the shutters are arranged at the level of the openings of buildings, of the door or window type, to ensure their shutter preventing inter alia the intrusion into the building in the absence of the owner of the premises.
  • the shutter generally consists of a trunk, arranged in the upper part of the opening, it can be integrated into the lintel of the opening, especially during a new construction, or attached to the door jamb. opening, in case of renovation.
  • This box receives a winding shaft, also called tube or drum, on which rolls and unwinds an apron composed of articulated slats, this apron allowing the closing of the opening when fully deployed, and on the contrary the release of the opening when fully wound on the shaft.
  • the apron is generally guided in translation by slides arranged on the side walls of the opening. The upper end of the apron is secured to the winding shaft to maintain between the two elements when said apron is completely unrolled from the shaft.
  • a first mode of design similar to that described in the patent application published under the number FR-2696779 , consists of the use of rings reported on the winding shaft and immobilized relative thereto, the rotation of the shaft causing that of the rings. These rings receive in pivot connection a hooking link articulated with the upper end of the deck. This deck is thus secured to the winding shaft through the rings and the attachment link.
  • the rings are threaded from the ends of the shaft, which have for example a grooved form, cooperating with teeth arranged on the inner diameter of the ring, to ensure the immobilization in rotation of the ring relative to the tree.
  • the rings are then immobilized in translation on the axis by means of a locking system, for example of the screw type.
  • the articulation of the attachment link on the shaft requires the use of two rings relative to which one end of said link is mounted in pivot connection.
  • such a design of the device requires the disassembly of the winding shaft disposed in the trunk, in order to extract the rings and proceed to their replacement.
  • Another way of designing the assembly between the deck and the winding shaft consists in the use of a hooking link having a curved shape adapted to that of the winding shaft.
  • the attachment link is assembled directly on the shaft, for example by means of hooking tabs, a stapling system or directly by screwing on the shaft.
  • the shutter assembly devices allowing the connection between the deck and the winding shaft, comprise locking means whose function is to prevent the rise of the deck when it is deployed and closes the opening of window or door.
  • These assembly devices comprise for this at least two attachment links arranged between the deck and the winding shaft, these links being articulated to one another, the first link being connected to the shaft of winding and the second link being connected to the deck, the links assembled for example by means of a system of hinges indisputedmontable, the articulation between the two links being arranged to generate a bracing when the deck is fully deployed and we tried to lift it.
  • the object of the present invention is to overcome the drawbacks of existing systems and to design a coupling device between the deck and the rolling shutter winding shaft which has a reduced number of easily adaptable elements between the shaft of the rolling shutter. winding and the deck while ensuring a perfect anchoring of the attachment link with the winding shaft. It also allows the locking of the apron preventing its rise when it is deployed and closes the opening of door or window.
  • the present invention relates to a coupling device for a roller shutter, allowing the connection between the deck and the winding shaft of said shutter.
  • the device comprises a connecting ring adapted to be arranged around the winding shaft, locking means in rotation and in translation being arranged between the ring and the shaft along its longitudinal axis.
  • the device comprises a hooking link between the deck and the winding shaft.
  • This attachment link has a first end which is mounted in pivot connection directly with the ring secured to the shaft and a second end which is integral with the upper end of the deck.
  • the device is remarkable in that the ring is flexible and comprises a slot so as to have two adjacent edges defined on each side of said slot.
  • the ring is adapted to be deformed so as to be spaced apart at its two edges, said spacing making it possible to pass and to position the ring around the shaft, said positioning allowing the positioning of the locking means in rotation and in translation of the ring on the tree.
  • the assembly in pivot connection of the link with the ring is configured to hold in place said locking means.
  • Such a design has the advantage of allowing the positioning of the ring on the shaft after it has been positioned and assembled inside the rolling shutter box.
  • Another advantage is essentially to be able to disassemble said ring in case of malfunction, especially due to wear. This disassembly of the ring is thus achieved without requiring disassembly of the winding shaft.
  • the rotational locking means of the ring relative to the shaft consist of a type of assembly mortise / tenon. These means consist of at least one longitudinal groove arranged on the winding shaft, this groove forming the mortise. Furthermore, a projecting portion is arranged on the inner diameter of the ring. This projecting portion is arranged at the end of at least one of the edges of the ring and forms the post, adapted to be inserted into the mortise. The positioning of the ring around the shaft makes it possible to introduce the protruding part into the groove, ensuring the implementation of the locking means.
  • the two edges of the ring each have a projecting portion having an inner side and an outer side, the inner sides of the projections being adjacent when the two edges are joined.
  • the two inner sides have an obliqueness adapted to allow the clamping of the outer sides on the lateral sides of the groove when the two projections are introduced into said groove and the two edges are joined. This ensures an anchorage between the ring and the winding shaft.
  • the groove has a dovetail shape.
  • at least one of the outer sides of the two projecting parts has a draft capable of allowing a dovetail assembly with the groove when the two edges are joined.
  • the two adjacent edges each have a shouldered shape.
  • the shouldered forms of the two edges are able to abut one on the other when the ring is disposed around the shaft and said edges are joined.
  • the attachment link comprises at its first end a notch of width corresponding to that of the ring.
  • the pivot link assembly of the link on the ring is arranged at the two adjacent edges so that said edges are held together and nested in the notch, which prevents their spacing.
  • the forms shouldered on the two adjacent edges are adapted to receive in pivot connection the first end of the link, the notch being positioned at the two shouldered forms in abutment, and able to maintain them in abutment position.
  • one of the edges comprises a transverse orifice opening
  • the other edge comprises a circular transverse stud adapted to be introduced into the orifice on the other edge during the abutment of the two shouldered forms.
  • this arrangement also allows to receive the link mounted in pivot connection at the adjacent edges.
  • the lateral sides of the notch each comprise a transverse opening opening.
  • the stud comprises an opening opening.
  • the orifices of the lateral sides and of the stud are able to cooperate when the link is positioned on the adjacent edges of the ring. These orifices allow the passage and positioning of a connecting pin inside, this axis for maintaining and pivoting the link relative to the ring.
  • the apron wraps around the ring mounted on the shaft.
  • the ring comprises an outer spiral shape on which the apron rolls up, the diameter of the ring being progressive.
  • the direction of the spiral depends on the winding direction of the apron around the ring.
  • This spiral design has the advantage of ensuring proper winding of the apron around the shaft. This spiral starts at one of the adjacent edges of the ring and ends at the other edge.
  • the connection in pivot connection of the link on the ring is arranged at the adjacent edges, said assembly being able to allow a winding of the link and the integral apron of said link in the progressive direction of the spiral.
  • the shutter apron closes a building opening when it is completely unrolled from the winding shaft.
  • the coupling device comprises means for locking the apron in the deployed position. These locking means are arranged between the ring and the attachment link so as to block the rotation between the two elements. Thus, the apron, secured to the second end of the link, can not to be reassembled because of the locking of the rotation of the link relative to the ring.
  • This conception differs totally from that known from the documents FR-2696779 and EP-0937859 and has the advantage of using only one link between the ring and the deck, the locking being made directly between the hook and the ring, at the pivot connection between the two elements.
  • abutment means are arranged between the link and the edge of the ring forming the final end of the spiral. These stop means are used to block the pivoting of the link relative to the ring preventing the ascent of the deck when it is placed on the door or window opening.
  • abutment means are constituted by a cleat arranged on the bottom of the notch of the link and extend on the outer side of the link.
  • the cleat is able to bear on the edge of the ring forming the final end of the spiral when the link pivots outwardly relative to the ring, that is to say in the direction favoring the lifting of the apron .
  • This stop then makes it possible to limit the pivoting towards the outside of the link and thus to prevent the lifting of the apron.
  • the ring is positioned around the winding shaft taking into account the winding direction of the deck, the progressive direction of the spiral being disposed on the side of the deck during assembly of the ring.
  • the rotational locking of the ring on the winding shaft is achieved by positioning the projecting portion on the inner diameter of the ring, forming the tenon, inside the groove on the winding shaft, forming the mortise.
  • the shouldered forms of the two adjacent edges of the ring disposed around the shaft are then positioned in abutment, the pivotally connected connection of the first end of the link then ensuring the abutment of the two edges and the locking of the ring on the tree.
