Description

The invention relates to a method of laying on the facade in front of

  the splaying of a door or window of a shutter block comprising a box containing the winding mechanism of an apron provided adapted to be deployed in the lateral wings of

guidance that overcomes said box.

  The invention also relates to support cleats for the implementation of this method of laying.

  The invention relates to the field of shutters for doors, windows or the like.

  In particular, the invention focuses on the problem of laying a roller shutter block in place.

  In this regard, such a shutter block is composed of a box housing the winding mechanism of an apron consisting of a juxtaposition of blades at least hinged together. This apron is designed to be deployed in front of a door, window or the like passing through a slot for this purpose in the box. Specifically, during deployment and folding maneuvers of the deck, the blades have their ends engaged in lateral guides of the guide, extending under the box. Through suitable fastening lugs or similar means, it is secured to these lateral guide rails.

  When such a roller shutter block is provided capable of being positioned in the frame of a door or window, during assembly, the operator places the block through the lower ends of the slides on the threshold of this door or window before tilting it into a vertical position, even apply against the joinery. Under these conditions, it is sufficient for this operator with one hand to hold the block in position, taking advantage of the other hand to fix, by screwing or otherwise, said slides, either against the frame of the masonry, or applied on the sleeping frame of the door or window.

  On the other hand, the assembly in front of the splay 35 of such a door or window, poses more difficulties.

  2886331 2 In particular, the operator must support the entire weight of this roller shutter block all the time before the installation of the first fixing screw.

  Thus, by presenting a first time this shutter block bearing against this facade, it must identify the drilling points and for this, said block must be kept perfectly squared.

  After drilling, the operator must once again lift and hold the roller shutter block against the wall for the engagement of the fixing screw, while manipulating the screwing tool. Note, moreover, that the operator can be relieved of the weight of the deck after installing at least one fastening screw at each of the side wings surmounted by the box housing the deck of the shutter.

  Finally, it seems obvious that such an application of a rolling shutter block can be done by a single operator so that the presence of at least two people on the site is necessary, especially since these operations pose usually occur in height.

  The present invention aims to meet these mounting constraints on the front of a roller shutter block in front of the splay of a door or window.

  For this purpose, the invention relates to a method of laying consisting of bringing back, applied, on both sides of the splay and substantially at the threshold of this door or window, a support cleat and to be based on these the lower ends of the side guide slides of the roller shutter block to raise the latter applied against said facade and ensure the installation of fixing means, in this case fixing screws.

  The invention also relates to support cleats for more particularly the implementation of the method above, cleat comprising at least one opening for the passage of a screw for attachment to the facade and, in combination, means of Positioning designed capable of cooperating with the splay to contribute to its positioning in wall 2886331 3 on the front and / or indexing means provided to cooperate with the lower end of a slide and retain it in position on said support cleat, in particular in a transverse direction, that is to say parallel to the facade.

  More particularly, the positioning means are designed to cooperate with the angle between a table and the threshold of the splay for the identification of the correct positioning of the support cleat on the facade.

  Other objects and advantages of the present invention will become apparent from the following description relating to an embodiment which is given for information only and not limiting.

  The understanding of this description will be facilitated with reference to the accompanying drawings, in which: - Figure 1 illustrates, schematically, a roller shutter unit reported applied to a facade prior to the splaying of a window; FIG. 2 is a diagrammatic representation in perspective illustrating the operation of laying a shutter block 20 according to the process according to the invention; - Figure 3 is a schematic representation of the splaying of a door or window, in the lower part of which are fixed in front of the support cleats according to the invention; - Figure 4 is a schematic perspective illustration of a support cleat according to the invention.

  As seen more particularly in Figures 1 and 2 of the accompanying drawings, the present invention relates to the field of shutters. It relates, more particularly, to a method of laying in front 1 of a shutter block 4 in front of a splay 2 door or window 3.

  As visible in these Figures 1 and 2, this shutter block 4 comprises a box 5 enclosing the winding mechanism of an apron (not visible) consisting of a juxtaposition of blades at least hinged together. In this regard, the casing 5 has a slot for the deck to allow it to deploy along slides 6 contributing to the lateral guidance of said apron blades.

  The box 5 overcomes these slides 6, while being secured to the upper end 7 of the latter.

  The laying method according to the invention provides, in the context of a first step, the attachment in front 1 of support cleats 8, cleats on which is able to rest the shutter block 4 through the lower end 9 backstage 6.

  In sum, after the installation of these support tabs 8 in the lower part of the splay 2, the operator comes to rest the lower end 9 of said slides 6 on these support tabs 8 before raising the shutter block 4 for the bring to apply against the facade 1. At this time, the weight of the shutter block 4 being fully supported by these cleats supports 8, it is easy to ensure its fixing by screwing or other.

  According to the invention such a support cleat 8 comprises at least one opening 10 for the passage of a screw for its attachment to the facade. Preferably, this cleat 8 defines a horizontal bearing surface 11 substantially adjusted to the cross section of a slide 6 so as to define an extension thereof at its lower end 9 once the shutter block 4 is placed.

  Advantageously, this support cleat 8 may be provided with positioning means 13 designed capable of cooperating with the splay 2 to contribute to its positioning applied to the facade 1. More particularly, these positioning means 13 are designed able to cooperate with the angle 14, between a table 15 and the threshold 12 of this splay 2, for the identification of the correct positioning of the support tab 8 on the facade 1.

  Thus, as can be seen in FIGS. 3 and 4, these positioning means 13 are defined by a lug 16, advantageously of cylindrical or semi-cylindrical shape, extending perpendicularly to the rear of the support cleat 8. This lug 16 can be made integral with the latter by breakable connecting means 17 which allow to detach from it after fixing the support cleat 8.

  According to the invention, it can be provided with indexing means 18 designed to cooperate with the lower end 9 of a slide 6 to retain it in position on the bearing surface 11 of such support cleat 8, in particular in a transverse direction D, that is to say parallel to the facade.

  In other words, these indexing means 18 are designed to prevent the lower ends 9 of the slides 6 from sliding on the bearing surface 11 of the support cleats 8.

  Advantageously, these indexing means 18 may additionally constitute positioning and retaining means applied to the front of the guide slides 6 at their lower end 9.

  According to an advantageous embodiment, these indexing means 18 are defined, at said bearing surface 11, by a plug 19 on which is provided able to engage said lower end 9 of a slide 6.

  In particular, this is usually defined by a U section section 20 leaning against a tubular section 21 defining, at the rear of the guide groove of the apron blades, a tubular channel very frequently used to ensure fixing functions. Thus, in this channel, at the upper end 7 of the slides 6, is engaged, usually, a fixing lug ensuring the connection with the box 5. Exactly, the plug 19 corresponding to the indexing means 18 may be provided adapted to be inserted into this channel at the lower end 9 of a slide 6.

  In a particular way to the invention, on its side 22 facing the front 1, said plug 19 defines a cam track designed able to gradually push the lower end 9 of a slide 6 against this facade when raising the block rolling shutter 4 on the support cleats 8.

  On its opposite side 23, said plug 19 comprises a hooking flange 24 forming a stop and designed adapted to prevent the release of said lower end 9 of a slide 6 of this plug 19 during positioning of the shutter block 4 on the cleats supports 8.

  Insofar as the installation on the front of this shutter block 4 is carried out in the manner already explained above, ie by presenting the lower ends 9 of the slides 6 to the right of said support tabs 8, the shutter block 4 being maintained, inclined, or almost horizontally with respect to the facade 1, then by rocking the shutter block 4 by rotation around said lower ends 9 of the slides 6 on said support tabs 8 to come and apply it against the frontage 1.

  Precisely, to ensure positioning of the lower ends 9 of the slides 6 on the support tabs 8, while the shutter block 4 is inclined relative to the front 1, the indexing means 18 are completed by pre-positioning means 25 extending above the bearing surface 11 in an inclined or even horizontal manner, in a direction opposite to this facade 1. Such prepositioning means 25 are designed to cooperate with the lower end 9 of a slide 6 presented in an inclined or horizontal position on a support tab 8 to hold said slide 6 on the bearing surface 11 of the latter.

  According to an advantageous embodiment, said prepositioning means 25 are defined by a tongue 25A extending above the bearing surface 11 in an inclined or even horizontal manner, in a direction opposite to the facade 1. at the beginning of assembly, the lower ends 9 of the slides 6 are presented in an inclined manner and engaged on these tongues 25A preventing said slides 6 from moving during the raising of the shutter block 4.

  Advantageously, a tongue 25A is, through an articulated connection or because of a flexible material design, designed to pivot relative to the support tab 8 to, starting from an inclined position, be straightened in a substantially vertical position under the impetus of raising the shutter block 4.

  According to a preferred embodiment, the tongue 25A 5 extends, at its free end, a plug 19 constituting the indexing means 18.

  In another embodiment not shown, these tabs 25A extend above the support tab 8 independently of such a plug 19.

  Furthermore, according to an advantageous embodiment, this tongue 25A is defined elastically foldable to allow its recovery from its inclined rest position, or horizontal and, during straightening of the slides 6, exert a restoring force on the end lower 9 of the latter in a direction opposite to the front 1 so as to maintain the lower end 9 of the slides 6 applies to the camming side 22 of the plug 19. This provides the advantage of keeping away from the front these ends 9 of the slides 6 and, thus, not to damage the paint or other decorative coating.

  Note that according to yet another embodiment, the indexing means 18, instead of a plug 19 provided adapted to engage in the lower end 9 of a slide 6, can adopt the form of at least one stop flange extending above the bearing surface 11 of a support cleat 8 so as to cooperate with said lower end 9 of a slide 6 to prevent the movement of the latter at least following a direction parallel to the facade 1.

  As is apparent from the foregoing description, the present invention responds, advantageously, to the problem posed.

  Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
