Definitions

  • the present invention relates to a shutter installation provided for fitting a window or a door.
  • the invention particularly relates to a rolling shutter installation comprising an apron formed of blades hinged together and guided on each longitudinal side by a slide, the apron being able to wind and unwind from or respectively to the lower edge of a window or door in the closed position.
  • the roller shutter installation includes an apron locking device in a locked and partially open position for which the lower blade of the apron is at a reduced distance from the lower edge of a window or door to prevent the passage of a person between the apron and the said lower edge.
  • the locking device comprises a slider mounted in translation in one of the apron blades, said slider being provided to traverse the face of the locking device opposite the apron, said face comprising at least three guide portions of the slider so as to guide the apron between different positions, including a gap position of the apron.
  • the document FR 3,009,577 which discloses a rolling shutter installation according to the preamble of claim 1, namely an installation comprising an apron formed of blades hinged together and guided on each longitudinal side by a slide, the apron can be unrolled to the lower part of a window or door in the closed position.
  • the installation comprises a cam, extending longitudinally, adapted to cooperate with a finger mounted in translation in a deck blade.
  • the cam has a rectilinear intermediate portion, and a bent upward portion forming a stop for the finger.
  • the cam also has at each end, upper and lower, a ramp to guide the movement of the finger.
  • the finger meets the upper ramp, which causes the movement of the finger in the blade, then the blade meets the intermediate portion.
  • the finger meets the lower ramp which pushes the finger to the left, before following another rectilinear part.
  • the cam is not suitable for all types of slides.
  • the invention aims to adapt to all types of traditional scenes and renovations, without creating specific scenes. It also aims to facilitate the installation of the installation, that is to say, to facilitate the adjustment of the positioning of the locking device relative to both the slide and the slider because of the elastic tongues.
  • At least one of the objectives is achieved with a shutter installation according to claim 1, comprising an apron formed of blades articulated together, the winding or unwinding around a shaft is provided by a drive means , the deck blades being guided on each side by a slide; the apron can be unrolled to the bottom of a window or door in the closed position.
  • the installation comprises an apron locking device in a partially open position for which the lower blade of the deck is at a reduced distance from the lower edge of the window or door, in particular insufficient to allow the passage of a person .
  • the frame extends longitudinally along the axis of the slide and has a face facing the deck blades.
  • the face opposite the apron has three portions traveled by said cursor.
  • the slider guides the apron with respect to the locking device during winding or unwinding.
  • each elastically deformable portion has an outer face facing the deck, said front face, and an inner face opposite to the outer face, said rear face.
  • the term elastically deformable portion of the face of the frame a movable portion between a rest position and a cursor passage position, said mobility being expressed mainly in the plane of the deck.
  • the skilled person will design the elastically deformable portions of the face of the frame and the elastic return device of the slider, so that during the passage of the cursor, the portion is deformed elastically while the cursor, in support against said portion translates in a plane of the apron and along an axis substantially perpendicular to the axis of the slide.
  • Each portion preferably comprises at least one elastically deformable tongue.
  • Each elastically deformable tongue is connected to a first end with the face of the frame opposite the apron.
  • Each tongue, near the first end can articulate or deform elastically between the rest position and the passage position of the slider setting in motion said tongue.
  • the movement of each tab near a second distal end, opposite the first end has a substantially circular arc trajectory.
  • the installation according to the invention makes it possible to improve the guidance of the cursor downhill as well as upwards thanks to the elastically deformable portions which force the cursor to come and position itself under the stop.
  • the guiding of the final blade end of the deck is thus improved.
  • Each elastic tongue extending towards the apron may, because of its elasticity, protrude and extend more towards the deck than the abutment or the lower ramp of the prior art.
  • the tongue protrudes towards the apron so that the spacing between the distal end of the tongues and the recess is 10 to 20 mm.
  • This characteristic makes it possible to offer a mounting tolerance of the locking device with respect to both the slide and the slider. If the locking device is placed in a manner that would be considered too far away for the abutment of the cam of the prior art, the length of the elastic tongue makes it possible to compensate for any positioning offset and makes it possible to make the tab extending to the apron with the cursor. This facilitates the mounting of the locking device.
  • the locking device according to the invention makes it possible to adapt to any type of slide.
  • the slider is mounted in the lower blade near one end thereof. This arrangement makes it possible to block in translation all the blades of the deck and to ensure that the reduced distance, that is to say the space left between the lower deck and the edge of the window, will remain fixed, preventing the passage of a person and avoiding the raising of the shutter from the outside.
  • the intermediate portion comprises at least one recess forming a fixed stop for stopping the slider when raising the apron.
  • the elastic locking tab allows the passage of the cursor through the elastic deformation thereof, the cursor running through the front face of the elastic locking tongue. Once the cursor has passed the distal end of the locking elastic tongue, the latter returns to its initial position, substantially inclined.
  • the elastic locking tab blocks, by the rear face, said cursor if it ever ascended immediately or if the restoring force of the elastic return device was not sufficient.
  • the recess is extended upwards by the stop.
  • the slider which has crossed the elastic locking tongue and which bears against the surface of the recess, can be guided without resistance to the fixed stop which stops the translation upwards.
  • the surface of the stop has substantially the shape of a cylindrical half-tube.
  • the abutment surface is oriented downwards and extends towards the opposite side to that of the recess surface by the rear face of the resilient locking tongue.
  • the fixed stop has the advantage of blocking the winding of the apron in a partially open position, so that the lower blade is at a reduced distance from the threshold of a window or a door. In the case where the cursor is not resting against the recess surface, the cursor is stopped in translation by the rear face of the resilient locking tongue which is substantially inclined.
  • the intermediate portion comprises a plurality of recesses and several elastic locking tabs distributed vertically along the intermediate portion. It is possible to choose different locking heights according to the wishes of the user.
  • the lower tab is used to direct the cursor out of the face next to the apron. Once the cursor has passed the distal end of the lower elastic tongue, it returns to its initial position, substantially inclined so as to block the rise of the cursor to the intermediate portion by the rear face of the lower tongue. The rear path allows to slide the slider longitudinally during the winding of the deck.
  • the resilient locking tab and the lower elastic tab project toward the apron so that the distance between the distal end of the tabs and the recess is 10 to 20 mm. Even if the frame is attached to a slide so that it is offset from a reference position, the cursor can cooperate with the back side of the tabs. This facilitates the mounting of the locking device.
  • the locking device according to the invention makes it possible to adapt to any type of slide.
  • the elastically deformable portions are made by spring devices, for example leaf spring.
  • the rear path comprises a groove in the frame.
  • the groove guides the cursor along the rear path of the frame.
  • the upper portion of the frame comprises an upper elastic tongue, placed at the upper end of the frame, projecting towards the slide, and having a front face and a rear face.
  • the upper elastic tongue at a first end, is integrally connected to the frame of the locking device.
  • the upper resilient tongue is provided to deform elastically at the passage of the cursor on the rear face of said tongue when the cursor, from the rear path of the slide, goes up to allow the winding of the deck.
  • the upper elastic tongue extends upwardly in a substantially inclined direction. Said upper tongue is arranged to guide the movement of the slider, during the descent of the apron, along the front face of the tongue, towards the at least one elastic locking tongue, sliding the slider mounted in translation in the blade .
  • the upper elastic tongue is, at rest, in contact with a face of the slide facing the frame of the locking device.
  • the upper elastic tongue makes it possible to constrain the cursor to follow the face of the frame opposite the apron, and prevents the cursor from descending through the rear path. The reliability of the apron guidance is improved.
  • each tongue has a substantially curvilinear profile and extends in a width of between 5 and 15 mm.
  • the cursor is a finger mounted on a plate in a tip engaged in the lower blade of the deck.
  • the plate can slide in a direction parallel to the length of the blade, and is biased resiliently in a rest position.
  • the elastic return device tends to push the finger towards the outside of the blade.
  • the finger is arranged at right angles to the plate, orthogonal to the plane of the unrolled deck.
  • the installation comprises a second locking device similar to the first, the second device comprising a second slider mounted in translation along an axis substantially perpendicular to the axis of the slide in the blade in which the first slider is mounted, the two blocking devices contributing to recenter said blade relative to the slides.
  • the frame is housed partially or totally in the slide.
  • the frame can be housed completely in the slide so that the frame is fully included in the volume of space of the slide.
  • the frame of the locking device is fixed inside a groove of the slide so that the frame is not visible from the outside when the apron is in the closed position. In the case where the frame is housed partially in the slide, it exceeds the volume of space of the slide and is visible from the outside.

  • the locking device is fixed to the slide by screwing.
  • the locking device comprises an intermediate plate extending parallel to the axis of the slide.

Said support bears against the lower edge of the window or the door and said holding element is inserted into a cavity of the slide so that a wall, of non-zero thickness, of said slide is located between the element of maintenance and the frame and rests on the support of the frame.
  • This feature has the advantage of blocking the translation of the locking device in a simple and inexpensive way.
