Description

Shutter device for shutter tunnel caisson, with element

  anchoring to the vault of the tunnel box, and tunnel box equipped with such shutter devices.

  The present invention relates to a shutter device for roller shutter box, with an anchoring element to the vault of the caisson, and a tunnel box equipped with two shutter devices according to the invention.

  More particularly, the invention relates to improvements made to the shutter device for shutter tunnel caisson box according to FR 2 803 330 or EP 1 114 913, as well as tunnel-box described in these patents.

  These patents describe a shutter device intended to close each of the lateral ends of a roller shutter tunnel box, the box having a substantially U-shaped cross-section, and having a roof resting on two longitudinal walls, the edge of which Each lower section is overlapped by one respectively of two reinforcing metal sections forming rails, generally of aluminum.

  The tunnel caisson is generally made in the form of a shell molded from a cellular synthetic material or foam, or with a honeycomb structure, delimiting a tunnel-shaped internal recess, the base of which between the two rails, is open to allow to accommodate a roller shutter with its operating device, for the winding-unwinding of the shutter apron, for example a belt pulley, a crank winch or an electric motor.

  The caisson-tunnel is intended to be integrated, under construction or after completion of this construction, at the lintel of a bay, such as window, French window or door, of the construction and in the surrounding masonry, to create a housing reservation of a shutter, as shown in Figure 1 and described with reference to this figure in the aforementioned patents, which will be referred to for further clarification on this subject.

  After being cut to the required length, substantially greater than the width of the bay to be equipped with a shutter, the tunnel box is closed at each of its lateral ends by a shutter device, preferably made of a synthetic material, and comprising mainly a cheek, which fits at least partly in said lateral end of the tunnel box, and a heel, substantially perpendicular to the base of the cheek on its inner face (turned towards the inside of the tunnel box) , and which is inserted between said rails when the shutter device is placed in the closed position of said lateral end of the tunnel box, the cheek comprising, at its upper part, an arcade coming opposite the internal face of the roof of the tunnel-box and piercing at least one opening for the passage of at least one tooth of an anchoring element of the cheek to the vault of the tunnel caisson by driving the tooth into the thickness of the vault through the corresponding opening in the arch of the cheek.

  Thanks to the fastening of the arch of the cheek to the vault of the caisson, on the one hand, and the maintenance of the lateral edges of the heel in the metal reinforcing profiles or rails at the base of the longitudinal walls of the tunnel box, d on the other hand, the two shutter devices of the tunnel box can be maintained in good closing positions of the lateral ends of this tunnel box and in good relative positions for the support of the axis of the shutter and its device. drive, because the cheeks of the shutter devices have, on their inner face, housing in which fix accessories of this axis and this drive device.

  But the shutter devices according to the aforementioned patents have several drawbacks.

  Firstly, they are limited to a one-piece construction, in which the cheek and the heel are in one piece, while shutter devices can be made each in two independent parts, respectively the cheek and the heel, which are assembled to one another during their assembly in a lateral end of the tunnel box.

  In addition, the locking of the arch of the cheek to the vault is provided by an anchoring element with two teeth projecting from a bent yoke and passing through two openings in the arch, which is bent in a semicircle to correspond to the shape of the vault in a semicircle, while there are vaults with cut sides.

  Finally, the anchoring element is not retained positively to the arcade of the cheek, so that it can be lost before its assembly, or that it can free itself eventually of the vault, and thus of the cheek, because of the vibrations due to the operation of the rolling shutter drive device, which can cause the teeth to gradually disincrust from the vault.

  The problem underlying the invention is to overcome these disadvantages, and to propose a shutter device that is better suited to the various requirements of the practice than those known from the aforementioned patents, and in particular that is positively retained in the arcade the cheek at least in the anchoring position thereof to the arch, and preferably also before anchoring, being captive and preferably a more economical embodiment.

  For this purpose, the shutter device according to the invention, of the type presented above and known from the aforementioned patents, is characterized in that said at least one tooth protrudes from a first flap of said anchoring element, pivotally mounted on said arch of the cheek, so that said at least one tooth engages in said at least one opening of the cheek arch and in the vault by pivoting with said first flap, below and around said arch of the play.

  According to a first advantageous embodiment, in which the anchoring element is captive, said first component of the anchoring element is pivotally mounted on the arch of the cheek by at least one film hinge pivotally attaching the first flap on the cheek.

  In this case, it is preferable that the first flap of the anchoring element is pivotally attached by a first film hinge to a second flap of said anchoring element, itself pivotally attached by a second film hinge at the edge. upper flange, substantially perpendicular to the arcade of the cheek along its outer edge, the side opposite the tunnel box and forming a stop limiting the interlocking of the cheek in the lateral end of the tunnel box, the width of said second flap being substantially equal to the height of the flange at this level, to suit the well-known structure cheek with flange bearing against the corresponding lateral end of the tunnel box.

  Advantageously, in this embodiment, the anchoring element is molded in one piece with the cheek.

  According to another advantageous embodiment, wherein the anchoring element is positively attached to the cheek in anchoring position, while being manufactured independently of the cheek, and therefore more economically, the first component is pivotally attached by a hinge edge to a second flap of the anchoring element, said second flap being removably attached to the arcade of the cheek.

  In this case, the shutter device may have at least one of the following characteristics: the anchoring element is molded into a piece attached to the arch of the cheek; - The anchoring element is removably mounted by clipping on said arch of the cheek; and - the anchoring element is removably mounted on the arch of the cheek by at least two lateral pins of the second flap, which engages, preferably by elastic clipping, each in a retaining housing on the arcade of the cheek.

  Advantageously, each tooth is substantially perpendicular to the first component of the anchoring element, so that each tooth can engage substantially vertically in the thickness of the arch, and the first component can be applied against the lower edge of the element. arch of the cheek.

  As known from the two aforementioned patents, the anchoring element may comprise two teeth spaced apart from one another, substantially in the same plane, and which each pass through one respectively two openings spaced substantially the same distance that the two teeth and made at least partly in the inner edge, turned towards the inside of the box-tunnel, the arcade of the cheek.

  The invention also proposes a tunnel box for shutters, of the type presented above, with two shutter closing devices for the lateral ends of the tunnel box, and each shutter device of which is in accordance with the present invention and as presented above. .

  Other advantages and features of the invention will emerge from the description given below, without limitation, of embodiments described with reference to the accompanying drawings in which: - Figure 1 is a partial schematic exploded perspective view of a shutter device with anchoring element, seen from the side of its outer face, and facing a lateral end to be closed of a caisson box, - Figure 2 is a perspective view of the shutter device of Figure 1 FIG. 3 is a perspective view of the shutter device of FIGS. 1 and 2, seen from the side of its external face and whose anchoring element is in the anchoring position, FIG. 4 is a view similar to FIG. 2 showing the shutter device with its anchoring element in the anchoring position, FIG. 5 is a vertical and longitudinal sectional view of the shutter device of FIGS. 1 to 4 in the position of FIG. FIG. 6 shows a side end of the tunnel box of FIG. 1, with the anchoring element in position on the arch of the cheek, before the engagement of the teeth in the thickness of the arch; and 7 are perspective views of another exemplary shutter device, respectively shown on the side of its inner face and its outer face, and provided with a one-piece anchoring element with the arch of the cheek. and FIG. 8 represents, in side elevation, the shutter device of FIGS. 6 and 7, the anchoring element of which is represented, in solid lines, in its position before anchoring in the vault, and in broken lines in FIG. its anchoring position.

  As represented in FIGS. 1 and 5, the tunnel caisson 1 consists of a vault 2 supported by two longitudinal walls 3 and 4, the assembly being made in the form of a molded shell based on polystyrene, possibly with a honeycomb structure. The tunnel caisson 1 thus has an inverted U-shaped cross-section, the internal recess of which is in the form of an open tunnel at its base and which extends from one to the other of its two lateral ends, of which only one 5 is visible in FIGS. 1 and 5. The opening at the base of the tunnel caisson 1 is delimited between two aluminum reinforcing profiles 6 and 7, forming rails, and each of which overlaps the lower edge of the one respectively longitudinal walls or jambs 3 and 4.

  Each of the lateral ends such as 5 of the tunnel caisson 1 is intended to be closed by a shutter device 8, a first embodiment of which is shown in FIGS. 1 to 5.

  This shutter device 8 is fitted laterally into each lateral end so as to close this lateral end 5 in a substantially airtight manner coming from the internal recess of the tunnel caisson 1.

  The tunnel caisson 1 thus closed at its two lateral ends is intended to be integrated with the lintel of a window embrasure or door of a building, as well as in the surrounding masonry, on the sides of the upper edge of this embrasure or bay , in particular being embedded in this masonry by its two lateral ends such as 5 and its vault 2, as shown in Figure 1 of the two aforementioned patents, and in such a way that its internal recess opens, by the opening of its base, in this bay or embrasure, to be able to accommodate a shutter equipped with its operating device.

  The shutter device 8 according to FIGS. 1 to 5 consists mainly of a cheek 9 and a heel 10, which may be in one piece, for example molded from a synthetic material, or assembled one to the other. other, before or during mounting in the lateral end such as 5 of the tunnel box 1.

  The cheek 9 comprises a plate 11 which, in the closed position of the lateral end 5 by the shutter device 8, extends substantially perpendicularly to the walls 3 and 4 and to the roof 2, and is totally embedded in the lateral end. 5 (see FIG. 5), and a support rim 12 which extends perpendicular to the plate 11 and protrudes outwards on the external face of the plate 11, along its periphery except at its base. . This support edge 12, the thickness and width (perpendicular to the plate 11) are constant in this example, consists of an arcade 13 extended by two straight segments 14a and 14b lateral and vertical.

  In this example, as the vault 2 appears with cut edges, because it is connected to the walls 3 and 4 by their upper parts which are of linearly decreasing thicknesses from the roof 2 and to their lower parts of constant thicknesses, l arcade 13 of the support rim 12 is also cut-sides of corresponding shape, because the support edge 12 is intended to come into contact with the inner faces and to intimately marry these internal faces of the vault 2 and walls longitudinal 3 and 4, to ensure the precise positioning of the cheek 9 relative to the corresponding lateral end 5 of the caissonunnel 1, and airtightness mentioned above.

  The outer edge of the support edge 12 is extended, perpendicularly to the edge 12 and projecting laterally outwards, thus in a plane substantially parallel to that of the plate 11, by a flange 15, which forms an axial abutment limiting the interlocking of the cheek 9, and therefore of the shutter device 8, in the lateral end 5 of the tunnel box 1, coming into contact with this lateral end 5. As a result, the collar 15 reinforces the watertight barrier at passage of the air from the internal recess of the tunnel caisson 1, which is formed by the support edge 12 in contact with the inner faces of the walls 3 and 4 and the roof 2.

  The heel 10 is connected to the base of the plate 11 of the cheek 9, and extends perpendicularly to the plate 11 and projecting inwards on the inner face of the plate 11, with side pads 10a which each side, slide in the rails 6 and 7 of the tunnel caisson 1, when the heel 10 is slid into the lateral end 5 of the tunnel box, optionally at the same time as the cheek 9.

  The heel 10 can support, on the one hand, the mass of the shutter hooked to the plate 11 of the cheek 9 by resting on the seat of the masonry provided for this purpose, and on the other hand, the box -tunnel 1 during its integration in the masonry.

  To mechanically link the flange 9 to the vault 2 of the tunnel caisson 1, after the shutter device 8 has been mounted in the lateral end 5 of the tunnel caisson 1, an anchoring element 16 is mounted on the flange 9 and has two teeth 17 bevelled, spaced from each other substantially in the same plane, and which can be embedded substantially vertically and from bottom to top in the thickness of the roof 2, from the inside of the arch 13 of the bearing rim 12, each passing through one respectively of two guide openings 18 formed essentially in the inner edge of the upper part (in this horizontal example) of the yoke 13, and partially in the upper edge of the plate 11, as shown in Figures 2, 4 and 5.

  This anchoring element 16 with the teeth 17 is an individually molded part made of a rigid plastic material and removably attached to the cheek 9. The two teeth 17 are rigidly projecting on an edge (corresponding to a long side) of a first rectangular flap 19 of this element 16, and extend substantially perpendicularly to this flap 19, each being rigidified by a small rib 20 connecting the flap 19. This flap 19 is pivotally connected about a hinge edge 21, corresponding to the long side opposite its edge supporting the teeth 17, to a second rectangular flap 22 of the element 16, and the second flap 22 is attached by resilient clipping against the outer edge of the arch 13 of the bearing rim 12, in a notch provided for this purpose in the collar 15.

  The removable assembly by elastic clipping of the element 16 on the yoke 13 is ensured, for example, by two nipples 23, each projecting on one respectively of the two small sides of the second flap 22, and each of which snaps elastically in a delimited housing, on one respectively of the sides of the notch in the collar 15, between the edge of this collar 15, on its inner face, and a lug 24 projecting on the arch 13.

  When mounting the anchoring element 16 on the arch 13, the second flap 22 is first snapped elastically onto the arch 13, placing the second flap 22 in the notch of the flange 15 and engaging , preferably simultaneously, each of the nipples 23 in its housing between the corresponding lug 24 and the corresponding edge of the flange 15, so that the first flap 19 extends downwards and towards the plate 11, in the defined volume by this plate 11 and the support edge 12, and that the teeth 17 on the first flap 19 extend upwards and towards the openings 18 in the arch 13 and the upper edge of the plate 11, as shown on Figure 5.

  Then, the operator presses up on the first flap 19, which pivots with the teeth 17 in the above-mentioned volume, until the first flap 19 bears against the lower face of the arch 13. pivoting of the flap 19 relative to the flap 22, which bears against the outer face of the yoke 13, the teeth 17 pass through the openings 18 which guide them and sink upwards into the thickness of the vault 2, by ensuring the anchoring of the arch 13 of the support edge 12, and therefore of the cheek 8, to the arch 2.

  This anchoring is thus obtained by a pivoting of the teeth 17 and the first flap 19 of the anchoring element 16 below and around substantially the arch 13.

  The second example of the shutter device 8 of FIGS. 6 to 8 differs essentially from that previously described with reference to FIGS. 1 to 5 only in the embodiment of the anchoring element 16 ', so that the same reference numbers are used. in FIGS. 6 to 8 to designate the same members or members similar to those shown in FIGS. 1 to 5, which will not be described again, and only the anchoring element 16 'is hereinafter described. specific to this second example.

  This anchoring element 16 'is not a separate piece removably attached to the arch 13 of the cheek 9, but the element 16 is molded in one piece with the cheek 9.

  On the anchoring element 16 ', there are two teeth 17 bevelled substantially parallel in the same plane, spaced from one another in this plane, and rigidly projecting along a long side of a first rectangular flap 19, substantially perpendicular to the flap 19, with a small rib 20 for stiffening between each tooth 17 and the flap 19, the two teeth 17 passing through two openings 18, spaced apart from each other in correspondence with the spacing of the teeth 17, and formed in the arch 13 and the upper edge of the plate 11 of the cheek 9.

  As in the previous example, to sink from below upwards in the thickness of the roof 2 of the tunnel caisson 1, in the lateral end 5 of the latter, the teeth 17 pivot with the flap 19 from below. and substantially around the arch 13.

  But in this second example, the flap 19 of the anchoring element 16 'is pivotally connected to the yoke 13 of the bearing flange 12 of the flange 9 by at least one hinge-film coming from molding with the flap 19, the ribs 20, the teeth 17 and the cheek 9, and attaching the anchoring element 16 'to the cheek 9.

  This hinge-film, in the form of a thin deformable tongue, can attach the flap 19 pivotally to the outer edge of the arch 13, in a notch of the flange 15, or the edge of this flange 15 in this notch, so that the anchoring element 16 'leaves the mold in the extended position, as shown in FIGS. 6 and 7 and in full lines in FIG. 8, the shutter 19 being inclined upwards, above the arch 13, and towards the openings 18, with the teeth 17 facing upwards and outwards of the cheek 9.

  From this position, the teeth 17 and the flap 19 may be pivoted substantially around the outer edge of the yoke 13 and at an angle of more than 270, first downward, from the outside and from below. the arch 13, then upwards, until the flap 19 comes into abutment against the lower face of the yoke 13, in a final position in which the teeth 17 have passed through the openings 18 and penetrated into the thickness from the vault 2.

  More specifically in the example of Figures 6 to 8, the flap 19 is pivotally attached by a first film hinge 21 ', along its long side opposite the one carrying the teeth 17, to a second rectangular flap 22', which in turn is pivotally attached by a second film hinge 23 ', along its long side opposite that of the film hinge 21', to the upper edge of the flange 15. The width of the second flap 22 'being substantially equal to the height of the flange 15 at the level of the attachment of the anchoring element 16 'to this flange 15, the pivoting of the anchoring element 16' around the yoke 13 is obtained to bring about the teeth 17 in the anchoring position in the roof 2, that the second flap 22 'first bears against the outer face of the flange 15 and the arch 13, then that the first flap 19 bears against the lower face of the arch 13, when the teeth 17 have arrived in the anchoring position .

  It is understood that the operation of the second example of anchoring device 16 'is functionally identical to that of the first example of anchoring element 16 of FIGS. 1 to 5, with the additional advantage that the anchoring element 16' Figures 6 to 8 is captive, since molded in one piece with the cheek 9.

  But in both cases, the anchoring element 16 or 16 'is positively retained on the arch 13 of the cheek 9, in the anchoring position of the teeth 17 in the roof 2. In both cases, this anchoring is ensured after a pivoting movement of the anchoring element 16 or 16 'substantially around the arch 13 and below it.

  It is also understood that the anchoring element 16 or 16 'can also be used in the case of a semicircular vault, and that it is then sufficient to adapt the shape of the flap or two parts of the anchoring element, as well as the shape of the film hinge or hinges so that these components are bent with a curvature substantially corresponding to that of the arch 13, which is then bent with a curvature corresponding to that of the vault 2.
