Definitions

• the invention relates to a connection between a shutter tunnel box and a carpentry crossbar located below the edge of this box.
• the rolling shutters of dwellings are retained by structures that can be embedded in the surrounding masonry, and called tunnel boxes.
• These chests include an inner side, adjacent to the joinery of the window to be covered by the shutter.
• a space remains between the edge of the inner side and the joinery, which should be filled to improve the appearance of the connection, establish a seal and strengthen the thermal insulation of the building. This can be achieved by expanding polyurethane foam or silicone-type products, but the resulting connection is irregular and often contains poor workmanship, such as continuity defects and insulation losses.
• French Patent 2 924 464 describes a coupling device whose section is U-shaped and comprises a lower face and two lateral faces connected to the lower face and in contact with the two faces of the inner side of the trunk.
• This connection is engaged on the side of the box and lowered until its underside touches the top rail of the joinery, thus establishing one seal. It is retained in place by bringing the lateral faces closer by screwing a bolt until they enclose the side of the chest with sufficient pressure.
• This design has the disadvantage that the connection is bulky and heavy, and the chest flank must be drilled to receive the clamping bolts to a height sufficient to allow the vertical movement of the connection, which is also expensive.
• the subject of the invention is an improved fitting to be installed between the trunk of the roller shutter and the underlying carpentry and which is, in particular, less bulky, lighter and easy to install.
• the present invention relates to a rolling shutter arrangement
• a rolling shutter arrangement comprising a tunnel box disposed between an inner side and an outer side and a fitting adapted to be disposed between the inner side of a shutter tunnel box and a carpentry cross member.
• said fitting located below said inner side, said fitting comprising a frame engaged under the inner side, characterized in that said coupling has a U-shaped section with flanks pressing on the surfaces of the lower edge of the sidewall and a central portion under the lower face of this edge and in that it comprises a flexible seal attached to the frame and extending under the frame to the cross.
• the advantage of this design is that the frame can be fixed without adjustment of position at the bottom edge of the box, the seal deforming according to the space between this edge and the joinery, without a sufficient seal is compromised .
• the reinforcement advantageously comprises a U-shaped section composed of a central part arranged on the lower edge of the inner side of the trunk and two side flanks extending from the central part upwards, along two sides of the side of the trunk, by enclosing it.
• the seal can be integrated into the frame by a permanent connection, but it can be mounted on it by engaging a base portion of the seal, for example wider than a main part, in a receiving groove of the frame. This arrangement can be retained for one of the ends of the seal, or both, if for example the seal comprises a main part, intermediate to the bases, essentially arc-shaped downwards.
• Another advantageous seal comprises a curved lip directed substantially downwardly from the frame and then curved outwardly. This particular form of seal withstands wind directed towards the window by a limited deformation accompanied by an increase in sealing.
• the connector of the invention may comprise a rigid reinforcement, for example metallic, to stiffen the connection and protect the lower edge of the box.
• This reinforcement extends over all or part of the length of the frame and generally covers the underside of the edge, which is hollow.
• This reinforcement can be contained in a notch of the frame. It can extend into the lower, essentially horizontal, section of the armature, but it can also be bent and also extend into at least one of the sides of the armature.
• the connection can be further improved in several other ways, for example by adding a flexible gasket directed outwards to an apron of the roller shutter by adding a net holder, or a mounting bracket to the carpentry cross.
• direction and orientation indications such as vertical, horizontal, inferior, exterior or interior refer to the normal arrangement of the layout on a building and must be interpreted in this context, without otherwise limiting the invention. .
• FIG. 1 represents a general view of the invention
• FIGS. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 represent alternative embodiments of the coupling.
• a trunk (1) called tunnel trunk of a rolling shutter is embedded in a masonry (2). It comprises an outer flank (3) and an inner flank (4) which will be discussed here, and which are directed downwards by surrounding a storage cavity and suspension of an apron (5) of the flap.
• the cut of a carpentry, not shown completely, passing through the masonry (2) comprises an upper cross member (6) extending a little below the lower edge (7) of the inner sidewall
• the coupling (8) according to the invention comprises a U-shaped section reinforcement (9) composed of an outer vertical flank (10) and an inner flank (11) both of which are vertical. lower portion (12) horizontally connecting the flanks. The flanks (10 and 11) rest on the surfaces of the lower edge (7), and the lower portion (12) bears under the underside of this edge.
• the armature (8) is completed by a seal (13) extending below the lower part (12) and which, in this embodiment, consists of a lip (14) extending vertically from the armature (9) then curving more and more outwards until it is tangent to the upper crossmember (6).
• the seal between the latter and the tunnel box (1) is then established. A possible wind can push the lip (14) inward, but then reinforcing the contact with the upper rail (6), and thus the seal.
• the lower part (12) has a notch in which a metal reinforcement (15) is housed.
• the reinforcement extends immediately below the underside of the edge (7) that it reinforces.
• the top of the outer flank (10) carries a mosquito net support (16) at its upper part, and a flexible seal (17), for example brush, rubbing against the apron (5).
• the inner side (11) carries a bracket here at right angle (18), consisting of a vertical wing (19) extending downward and a wing horizontal (20) lower fixed to the upper rail (6) by screws (21).
• Figure 2 illustrates the connection (8) of Figure 1 in the isolated state.
• the lip (14) is fixed to the lower part (12) and extends under the inner side (11). It is vertical in the free state.
• the mosquito net support (16) appears as an open groove upwards.
• the inner side (11) has an upper groove (22) for receiving fastening lugs (23) of the vertical flange (19) of the bracket (18).
• the flanks (10 and 11) finally each have a lower groove (24 or 25), and the lower face (12) a groove (26). All these grooves open outward, to remain accessible.
• the seal (17) is supported by being engaged in the groove (24), but the grooves (25 and 26) remain free.
• FIG. 3 shows that the notch for receiving the reinforcement can extend in a sidewall of the armature, for example the outside flank (10), the reinforcement, now (27), being then bent.
• the notch could also extend into the inner side (11), and the reinforcement, then (28) would be doubly bent and U-shaped section. This is shown in Figure 4.
• the seal (13) with lip (14) could be replaced by a seal (29) of similar shape and also comprising a lip (14), but provided with a base (30) engageable in the groove (25) lower side of the inner side (11), which represents Figure 5.
• the joint would then be removable.
• This embodiment differs little from the previous one, the joints (13 and 29) having almost similar shapes and positions.
• FIG. 6 shows that the lip seals (14) could be replaced by different seals, comprising an arcuate main part (31) and two bases (32 and 33) at their ends, engaged in the grooves ( 24 and 25) of the flanks (10 and 11). Sealing is still achieved by a deformation of the lower part of the seal against the upper cross member (6).
• This seal (34) could, as shown in Figure 7, be replaced by a seal (35) still provided with a lower portion (36) arc-shaped (less wide than the previous one) and a base single (37) engaged in the groove (26) of the lower part (12).
• flanks (10 and 11) are not always necessary, or only one of them can be used, the attachment to the sidewall (4) of the tunnel box (1) can be made by the lower part (12).
• the connection can be in various materials, metals or polymers in particular.
• the reinforcement will be especially useful if the connection is in simple polymer.
• the bracket (18) can thus be attached to the upper rail (6) by any means.
• the unit reinforcement can be replaced by several associated reinforcements. Other forms for the reinforcement or reinforcements are conceivable and depend on the desired inertia.
• the reinforcement or reinforcements may be added to one or more reinforcements present in the trunk (4).
• the fixing lug or tabs may be flat, bent at three points (L-shaped with a central pan of intermediate orientation to wings located on either side of it) or have any other form allowing the connection between the cross member upper (6) and the chest (4). They can be screwed.
• the profile can also be integrated in the trunk (4) during its manufacture by overmolding for example; in this case there is no need for fixing between the box (4) and the section (8).
