Description

The invention relates to a rolling shutter installation in a building opening, such as a window or door, surmounted by a lintel comprising an open reservation towards the interior of the building for the installation, from the inside, of a roller shutter mounted on a winding shaft supported in the vicinity of each end by a cheek fixed in the upper part of a window frame.

The term "carpentry" designates a dormant frame, generally equipped with at least one opening, which is fixed in the opening of the building, this joinery can be made of various materials, wood, plastic or metal, including aluminum.

For such an installation, the joinery equipped with the shutter is manufactured in the factory. The entire carpentry and shutter is set up once at the site of a building under construction. This solution is particularly interesting from the point of view of cost, because the workforce on site is reduced, a single intervention being necessary.

Research has been carried out to improve the acoustic and thermal performance of such a solution, and to avoid or limit an inner projection of a shutter box, lacking aesthetics. According to the patent application EP-A-1,548,224 In the name of the plaintiff company, the lintel is provided with a flat U-shaped reservation housed in the shell and open towards the interior of the building. A carpentry with a half-box wrapping the shutter is installed in block bay. This solution includes a trapdoor opening towards the interior of the building, which is often considered a nuisance by the inhabitants, and is therefore a disadvantage.

An installation comprising the features mentioned in the preamble of claim 1 is known to FR 2777938 A .

The invention aims, above all, to provide a rolling shutter installation which, while being simple and quick to perform, no longer has the disadvantage of a trap door located inside the building. It is desirable to have good thermal and sound insulation.

Referring to the drawings, in particular Fig. 1 and 2 , we can see a V installation of shutters in an opening A of a building, such as window or door. According to the representation of Fig. 1 , the outside of the building is on the right and the interior, for example a dwelling, is on the left. Generally, this is a new building under construction, but the invention also applies to old buildings, especially under renovation.

The opening A is surmounted by a lintel 1 having a reservation 2 open towards the interior of the building, that is to say to the left according to Fig. 1 . It is thus possible to set up, from the inside, a shutter B mounted on a winding shaft 3 supported towards each end by a cheek 4. The housing of the shutter B is delimited by a prismatic or partially cylindrical surface whose generatrices are parallel to the winding shaft 3, itself parallel to the longitudinal direction of the lintel. The cheeks 4 are located towards the transverse ends of the reservation 2. As visible on Fig. 2 , a cheek 4 comprises in its central region a bearing 5 for rotatably mounting one end of the shaft winding not shown on Fig. 2 .

The cheeks 4 are fixed on the upper part of a frame 6 of joinery 7 which can be made of any suitable material, including wood, or plastic, or metal including aluminum or light alloy. The frame is generally equipped with an opening, not shown. The fixing of the cheeks 4 can be provided by means of metal parts screwed to the joinery and not shown.

The cheeks 4 are arranged projecting outwardly. The whole of the joinery with the flap B and the tree 3; supported by the cheeks 4, is prepared in the factory and delivered ready for assembly on the construction site of the building. This assembly constitutes a half block bay, part of the housing of the shutter being constituted by the reservation 2.

This reservation 2 in the lintel is also open downwards so that it has substantially the shape of an inverted L.

The lintel 1 can be made using a prefabricated element E ( Fig. 2 and 3 ) in which reservation 2 is provided. At each of its ends, the element E is supported by means of a honeycomb block G of parallelepipedal rectangle whose large dimension is vertical, this block being housed in the reservation 2. The block G is placed on the upper end of the table T of the window, the assembly then being embedded in a dressing of binder, for example mortar. The element E comprises in the upper part an upstanding rectangular parallelepipedic cavity E1 which will serve as formwork for the production of the bending-resistant part of the lintel in the form of reinforced concrete, metal reinforcements ( Fig.1 ) being disposed in this cavity, the concrete being poured therein. Of course, this embodiment of the lintel is not limiting.

As visible on Fig. 4 each cheek 4 is fixed at the head of the lateral uprights of the frame 6. A slide 8 fixed to the joinery 7 is provided for the shutter below the rear part of each cheek 4. The cheek 4 is essentially flat, with a contour adapted to the circumstances. In the example shown, the cheek 4 has a substantially square contour whose angles are sliced, for example at 45 °, with the exception of the lower rear corner. The cheek 4 has a horizontal lower edge with two rectangular vertical openings 9, open downwards, the facing vertical faces are provided with vertically tiered hooking notches 10. The notches 10 are provided to allow sliding parallel to the shaft 3. These notches 10 are, for example, prismatic with horizontal edges perpendicular to the cheek 4 and parallel to the shaft 3.

The housing of the shutter is closed inwards by a board 11, for example PVC, fixed at the head and the front of the frame 6. The board 11 is essentially vertical with the upper part an extension 11a inclined towards the front, having at its upper end a vertical bar 11b which bears against the vertical vertical face of the lintel. The board 11 thus has a concavity facing outwards to complete the volume of the reservation 2 for housing the flap. The offset h ( Fig. 1 ) towards the interior of the building, created by the inclined portion 11a, with respect to the inner face 1a of the lintel is less than the thickness e of a coating 12, in particular insulating provided inside the building. If necessary, the board 11 could be entirely vertical, with a sufficiently deep reservation 2.

The coating 12 is advantageously constituted by an insulating layer and a sheet of a plaster-based material which are fixed above the opening behind the board 11, which is thus masked and not removable when the construction is complete.

For the transportation of the half-block bay manufactured in the factory, in order to keep the cheeks 4 properly spaced, it is advantageously provided, between the cheeks 4, a wall 13 ( Fig.2 ), in particular metal for example aluminum. The wall 13, with broken line contour, covers the cheeks 4 and the shutter forward. This wall 13 can be connected along its upper edge to the board 11. The front face 13a of the wall 13 is vertical in the vicinity of the vertical wall of the reservation 2. The wall 13 can remain in the installation, or be removed before set up the roller shutter in the reservation.

An external inspection hatch 14 forms a removable underside. This hatch 14 is constituted in particular by a partitioned hollow plate of plastics material, in particular PVC, the leading edge of which engages in, or snaps onto, a metal rail R, in particular aluminum; styling the lower front edge of the reservation 2 under which it is attached. The rail R is placed at the time of the elevation of the shell.

A fixing means 15 for the hatch 14 is mounted under each cheek 4 at the factory during the manufacture of the joinery and the half-bay block. At this time, the height dimension of the rail R is not precisely controlled. Indeed, the final position of the rail R is the result of a complex chain of dimensions involving several trades. It results from the dimensions of realization of the structural work, window sills or door sills, and the dimensions of realization of the window itself.

To make it possible to compensate for these possible variations in dimensions, the fastening means 15 is adjustably mounted at least in height under each end flange 4.

This fixing means 15 is advantageously formed by a heel 16, clearly visible on Fig. 6 and 7 , in the form of angle, in particular of plastic, whose edge is horizontal, parallel to the lower edge of the flange 4. The heel 16 is stiffened by gussets 17 located in the concavity of the angle. The hatch 14 is fixed, in particular by screws S ( Fig.7 ), against the underside of the horizontal wing of the heel 16.

The heel 16 comprises at least one and preferably two lugs 18 integral with the vertical flange of the angle and projecting, perpendicularly to this vertical flange, on the opposite side to the gussets 17. The lugs 18 have a prismatic shape with a rectangular section, complementary to the section of the lights 9 so as to be engaged in these slots by sliding in a horizontal direction perpendicular to the flange 4 and parallel to the winding shaft. The tabs 18 comprise on their vertical parallel faces notches or steps with horizontal edges having a profile complementary to that of the notches 10 of the lights 9 of the cheek 4. It is thus possible to adjust the height position of the heel 16 step by step, each step corresponding to the height of one notch. The tab 18 is slidably engaged at the chosen height.

It is further possible, by sliding lugs 18 in the slots 9, to adjust the position of the bead 16 in the transverse direction, perpendicular to the flange 4 and parallel to the winding shaft of the flap

Advantageously, the heel 16 has a vertical wall 19 ( Fig.6 and 7 ) extending downwardly below the horizontal flange of the angle, the opposite side to the gussets 17 relative to the vertical flange. This wall or blade 19 has a thickness k ( Fig. 7 ) substantially equivalent or slightly greater than that of a plaster or finishing coating 20 intended to cover the raw table T.

The face of the blade 19 located on the side opposite the hatch 14 is applied against the table T before it is covered by the plaster layer 20. Because the thickness k of the blade 19 corresponds to that of the plaster layer 20, there is no risk that the external inspection hatch 14 placed and adjusted to the dimension between the facing faces of the opposite blades 19 is covered at the end and blocked by the plaster layer 20. The blade 19 is an intermediate piece that requires the installer of the half bay block to put the hatch 14 sufficiently behind the raw table T.

Preferably, the external inspection hatch 14 is formed by a hollow plate ( Fig.2 ) of partitioned plastic parallel to the direction of the winding shaft 3. The width of the hatch 14 can be adjusted by cutting to adjust to the depth of the reservation 2.

Referring to Fig.8 and 9 , we can see a variant according to which the fixed cheek 4 ', constituting a flange for supporting and guiding the rolling shutter deck B, is made of sheet metal. The fixing means 15 of the hatch 14 is constituted by an adjustable heel 16 'formed by a section, of horizontal edge orthogonal to the shaft of the shutter. The heel 16 'comprises a vertical wing 21 secured to a horizontal base 22 under which the hatch 14 is fixed.

The vertical wing 21 is secured, on the side facing the cheek 4 ', a set of ribs 23, comb-shaped. The ribs 23 are constituted by horizontal slats, orthogonal to the wing 21, vertically spaced.

The lower part of the cheek 4 'has an opening 24 having a horizontal lower edge, formed by a return 25 folded horizontally.

The return 25 can be fitted, by horizontal sliding, between two ribs 23, which allows a height adjustment of the heel 16 'and the hatch 14. Sliding also allows a transverse adjustment.

The heel 16 'further comprises a wall 19' extending below the base 22, from the edge of the latter turned towards the table T. The lower edge of the wall 19 'is bent at right angles to the Table T according to a return 26 which is applied against the table T. The virtual thickness k of the wall 19 'is determined by the width of this return 26. This virtual thickness is equivalent to the actual thickness of the wall 19 of Fig. 7 and is equal to or greater than the thickness of the plaster or plaster layer 20. The wall 19 'with its return 26 performs the same function as the wall 19, which function consists in avoiding the covering of the hatch 14 by the plaster.

To further reduce this risk of recovery, it can be provided on the wall 19 ', as illustrated in FIG. Fig.8 , a recess 27 defining two vertical zones transversely offset. The upper zone, the more distant from the table T, delimits the housing of the hatch 14. The lower zone comes flush with the coating 20.

Of course, the wall 19 'could be located in a single vertical plane, without recess 27.

This being so, to achieve a rolling shutter installation according to the invention, the procedure is as follows.

The half bay block consisting of the joinery 7 at the head of which are fixed the two cheeks 4 supporting the roller shutter shaft 3 and the flap B wound on this shaft are prepared in the factory. The board 11 is also installed and the heels 16 are placed in the cheeks 4 for subsequent adjustment.

On the building site, the lintel 1 is made with the reservation 2. Just after the shell, the half bay block is placed from the inside to close the opening A. The cheeks 4, the flap B, and possibly the front wall 13, are arranged in the reservation 2. The installer performs this installation in accordance with the installation requirements and levels.

Outside, it remains to install the inspection door 14. For this, the installer first adjusts the height position of the two heels 16 in the lights 9 of the cheeks 4. The adjustment is made by choosing for the legs 18 the level of 10 notches best adapted in height to ensure a horizontal installation of the inspection hatch 14 and engage the front edge of the hatch 14 in the rail R. The installer then pushes each heel 16 until the blade 19 comes to bear against the raw table T.

If necessary the length of the hatch 14 is adjusted to the distance between the facing faces of the blades 19 of the heels 16, and the width of the hatch 14 is adjusted to the depth of the reservation. The installer then fixes with screws S the inspection hatch 14 against the lower face of the horizontal wing of each heel 16.

When finishing the building, the raw tables T are covered with the plaster layer 20, without risk of blocking the inspection door 14. Inside, the coating 12 is put in place, with the thermal insulation covering board 11. The inspection door 14 located outside does not create any discomfort in the housing, particularly from an aesthetic point of view, and the thermal and sound insulation is quite satisfactory.
