Definitions

  • the present invention relates to a security device for mechanical shutters (or also called roller shutters) which automatically blocks them so that they cannot be opened from the outside, in particular in the event of a violation.
  • a shutter can be locked by using one or more lateral locks. It is understood that such a closing system is not automatic, and there is therefore a risk of forgetting to engage said latch when the shutter is opened.
  • Document FR-A-2 609 095 describes an automatic locking device for roller shutters.
  • the locking device essentially consists of a first series of sawtooth projections arranged vertically on the internal face of the box substantially facing at least one of the last two slats of the apron when the latter is in the fully lowered position and a second series of projections also sawtooth disposed on the outer face of the last two slats of the deck.
  • a second drawback lies in the fact that the two series of projections must be positioned precisely so that they interpenetrate when the shutter is unrolled.
  • Document BE-A-332 413 also describes an automatic locking device for a roller shutter which comprises a locking element provided with teeth and mounted on the side walls of the bay.
  • the teeth are directed outward relative to the winding axis and therefore the slats of the flap must be pushed inward to obtain a blocking of the upper slat in said teeth.
  • the upper slat or slat of the deck is directly connected to the winding shaft by an elastic band.
  • Document DE-A-25 18 356 describes a locking device for mechanical shutters comprising an elastic rod perpendicular to the winding cylinder of the shutter and which will lock against a movable stop integral with the apron when an attempt is made to reassemble the shutter from the outside.
  • Document EP-A-0 242 317 describes a locking device for shutters comprising a stop element which is fixed on the upright in which the slats of the shutter apron slide and a movable protruding element situated on one of the slats so that it fits into the stop element thus locking the shutter when trying to reassemble it from the outside.
  • the document CH-A-657 663 describes an automatic lock for closing a roller shutter.
  • This lock consists of a movable blocking element mounted on a hinge carried by the upper lamella of the roller shutter. When the shutter is closed, this blocking element engages under hooks present on the sliding amount of the shutter deck.
  • the object of the present invention is to propose an automatic locking device for mechanical shutters which is particularly simple and which avoids the drawbacks of the state of the art.
  • FIGS. 1A, 1B, and 1C represent perspective views of the automatic locking device according to a first preferred embodiment of the invention for three different situations.
  • Figures 2A, 2B and 2C show perspective views of an automatic locking device according to a second preferred embodiment of the invention for three different situations.
  • FIG. 3 represents a front view of the various constituent elements of a shutter according to a preferred embodiment of the invention.
  • Figure 4 shows more particularly a spring element according to a particular embodiment of the present invention.
  • Figures 5A and 5B show a perspective view in section of a tubular profile of an apron according to the present invention.
  • a winding shaft 1 makes it possible to wind the deck 3 of a shutter using a drive mechanism (not shown).
  • Spring elements 5 constitute the connection between the winding shaft 1 and the deck 3 made up of strips 31.
  • the spring elements 5 are configured so as to push the upper slats 31 of the deck 3 outwards relative to the winding shaft 1.
  • one of the upper slats 31 of the deck 3 is in the form of a tubular profile 33 provided at at least one lateral end and preferably at its two ends with a locking end piece 41 .
  • At least one stop element 11 and preferably two stop elements 11 are arranged on either side at the ends sides of the deck 3 and facing each other with at least one of the upper strips 31 of the deck 3, and more particularly with the strip which is in the form of a tubular profile 33.
  • This stop element 11 consists of a series of projections in the form of teeth 13 which are themselves directed downwards and in the direction of the winding shaft 1.
  • stop elements 11 can be arranged on the internal longitudinal faces of a box 7 which contains the entire winding mechanism of the shutter.
  • stop elements 11 may be according to another embodiment arranged directly against the wall or the wall which runs along the upper strips 31 of the deck 3 unwound.
  • the spring elements 5 are simple flexible rods which directly connect the winding shaft 1 to one of the upper strips 31 of the deck 3 and preferably with the strip having the tubular profile 33 with the locking end pieces.
  • the spring elements 5 are flexible rods which on the one hand are directly connected to a strip or slat 35 itself fixed to the winding shaft 1, and on the other hand slide at the other end in a stirrup 37 fixed on a lamella or lower batten 36.
  • FIGS. 5A and 5B show more particularly the tubular profile 33 which is integral with one of the upper slats 31 of the deck 3 and which has at each of its two ends a nozzle 41 which is housed in a central opening 47 of the end of the profile 33 and which is held in this opening by means of a washer 43 and a fastener 45.
  • the device according to the present invention works as well for conventional spring elements as shown in FIGS. 1A to 1C as for spring elements connecting different lamellae as shown in FIGS. 2.
  • the automatic locking device according to the present invention can also be arranged on grids for closing the shop, for example.
  • a single stop element on either side at the lateral ends of the deck and which each comprises three teeth; it is understood that various modifications obvious to a person skilled in the art can be envisaged: for example two stop elements can be arranged one below the other or else the number of teeth can be increased so that it is no longer necessary to perform precise positioning when placing said stop elements.
