We first refer to Figure 1.

The motorized roller shutter shown in FIG. 1 comprises a motor member mounted on the axis of a winding drum 1. In the embodiments shown, this motor member is coaxial with the winding drum 1.

In other embodiments, not shown, this drive member is not coaxial with the winding drum, belt type links, chain, pinions or equivalent ensuring the transmission of rotation between the winding drum and the shaft leading of the motor unit.

Although the description is made with reference to a realization of motorized roller shutter, the invention can be covered for non-motorized roller shutters, as will be clear to the skilled person.

The axis of the winding drum 1 extends in a first direction D1.

The apron 2 of the motorized roller shutter, shown in Figure 1 in its extreme unwound position, can be at least partially wound around the drum 1, the rotation of the drum 1 being obtained by the electrically controlled motor member.

This electric drive member is for example a geared motor brake, or an electric motor provided with a gear reduction system meshing.

In the embodiment shown, the deck 2 of the motorized roller shutter is erased in a substantially vertical plane and the first direction D1 will be said longitudinal, this first direction D1 being substantially horizontal.

As will be clear to those skilled in the art, the invention can be covered for roller shutters whose erasure is not effected in a substantially vertical plane, the axis of the winding drum n ' nor is it necessarily horizontal.

The motorized shutters described in detail below as examples of embodiments will be of the vertical erase type, the axis of the winding drum being horizontal and placed at the top of a bay such as for example a door, a window or French window. A second direction D2, called transverse, perpendicular to the direction D1, defined with the first direction D1 a family of horizontal planes, a third direction D3, forming a trihedron with the other two directions D1, D2. The directions D2 and D3 define a family of transverse vertical planes.

In the embodiment shown, the deck 2 is formed by the assembly of blades 3, substantially identical to each other, these blades 3 being articulated along longitudinal axes of articulation.

These articulated blades 3 may be in particular wood, metal alloy or polymer material such as PVC.

The lateral ends of the blades 3 of the apron 2 slide in lateral guiding rails 4.

These lateral guiding rails 4 are for example U-shaped metal profiles mounted on the array of a bay, by screwing, bolting, riveting or any other equivalent assembly means.

The apron 2 comprises two end blades, the upper end blade 3a being connected to the winding drum 1.

In the embodiment shown in FIG. 1, this end plate 3a is connected to the winding drum 1 by two flexible strips 5.

The winding drum 1 is provided with two transverse lateral flanges 6 against which are placed the lateral edges of the deck 2 in the wound position.

The driving member and the winding drum 1 are placed in a box 7 whose bottom wall has an opening allowing the deck 2 to pass through.

To the right of the lateral ends of this opening abut the lateral guiding rails 4 of the apron 2.

Guide pieces 8 called tulip, of known type, are placed at the extreme end of the lateral guiding slides 4.

The bottom wall of the box 7, or underside, is not shown in the figures, for simplification.

This underside may be made of polymer material, wood, metal alloy, or any other equivalent material.

In the embodiment shown in Figure 1, the box 7 comprises a part 9 in the general shape of gutter.

Subsequently, this piece 9 will be called simply gutter.

This gutter 9 is generally parallelepipedal envelope and comprises a front outer face 10 and a rear outer face 11 substantially vertical, an upper outer surface 12 substantially horizontal and two lateral faces 13, 14 substantially transverse. This channel 9 has, in cross section, an inner face 15 U-shaped open downwards, this U-shaped profile opening on the two transverse side faces 13, 14.

This gutter 9 can be made of terracotta, extruded hollow brick, or even of concrete, or in the form of an extruded or molded profile made of a polymeric material or of a metal alloy profile such as a metal alloy. aluminum.

In a particular embodiment, this channel 9 is expanded polystyrene, an insulation board made of wood-cement fiber (fibragglo) covering at least one side of the box 7.

When the channel 9 is made of polymer material, cavities may be formed in the thickness of its walls, these cavities improving the sound or heat insulation, these cavities reducing the weight of the box relative to a box with solid walls.

Such cavities may for example be derived from the shape of the extrusion die.

This gutter 9 may be provided with an internal sealing lining and / or sound or thermal insulation.

For example, a flexible waterproof membrane may be glued or stapled to the inner face 15 of the trough 9.

A cork plate can also be placed facing the internal face 15 of the gutter 9.

Gutter 9 can be obtained by molding U-shaped profiles of great length and cutting this profile into desired length elements.

The final volume of the box 7 is delimited by the introduction, on the gutter-shaped piece 9, an underside and two side pieces. Other embodiments of the box can be envisaged.

Thus, for example, the box may include a gutter-shaped piece whose opening is placed towards the front of the box, a removable protective element forming a cover closing the gutter.

In other embodiments, not shown, the box comprises a tubular body made by assembling longitudinal profiles of wood, polymeric material or metal alloy whose ends are closed by side pieces. The upper part of the inner face 15 of the trough 9 may be curved and in an arc, as in the embodiment shown.

In other embodiments, not shown, the upper part of this inner face 15 is substantially flat, or else in an elliptical arc.

In the prior art, the lateral parts of roller shutter boxes are called, according to their configurations, shutter cover, cover, protective cover, flange, brackets, or tip.

The terms bonnet cover, protective cover, end caps or cover are generally used when the side parts have essentially or only a closure wall function, which must be aesthetically appropriate.

In contrast, the terms console, flange are used to designate side parts that directly support or not the axis of the winding drum.

For simplicity, in the following description, the side parts of the box will be called simply cheeks.

Indeed, in the embodiments shown, these cheeks form closure wall of the casing 7 and further have a winding drum shaft support function 1.

But, in other embodiments, not shown, these cheeks do not have winding drum shaft support function, this function being provided for example by consoles or flanges internal to the box.

In the embodiments shown, the box is intended to be at least partly placed in a masonry reservation, so that the cheeks are sealed in this reservation with the aid of a hydraulic binder. In these embodiments, the cheeks are not apparent do not have aesthetic cover function.

In contrast, in other embodiments, not shown, the outer faces of the cheeks of the box are at least partially visible and have an aesthetic side cover function for the box.

A motorized shutter box cheek will now be described in detail with reference to FIGS. 2 and following. The cheek 20 shown in Figure 2 has a main wall 21 and a lower substantially horizontal heel 22.

The lower bead 22 may be attached or integral with the main wall 21.

The main wall 21 comprises a transverse portion 23 provided with a central zone 24 forming a support for the axis 25 of the winding drum 1.

In the embodiments shown, this central zone 24 is a disk attached in a circular opening 26 of axis 25 formed in the transverse portion 23 of the main wall 21.

The assembly of this disk on the main wall 21 can be obtained by snapping, screwing, welding or any other equivalent assembly means.

In other embodiments, not shown, the main wall of the cheek is monobloc.

The outer face of the transverse portion 23, that is to say the face opposite to the internal volume of the box 7 when the cheek 20 is put in place, is provided with projections.

These projections extend perpendicularly to the outer face of the cross section 23.

With respect to the axis 25 of the winding drum 1, some of these projections are radial 27. Other projections 28 are annular with an axis 25.

These protrusions 27, 28 may come to reinforce, as it will appear later, taking the sealing binder of the box 7 in a reservation. The main wall 21 of the cheek 20 comprises, on its lateral edge, a longitudinal bearing wall 29.

This longitudinal bearing wall 29 is substantially transverse and parallel to the mean plane of extension of the transverse portion 23 of the cheek 20.

The transverse part 23 and the longitudinal bearing wall 29 are connected by a guide wall 30 whose inner face 31 is homothetic to the internal face 15 of the gutter 9.

This inner face 31 of the guide wall 30 is intended to come facing and bearing at least partially against the inner face 15 of the gutter 9 when the cheek 20 is in place on the gutter 9. The transverse portion 23 of the cheek 20 is set back towards the inside of the box 7 with respect to the longitudinal bearing wall 29.

This shrinkage, of axial dimension substantially equal to the width of the guide wall 30, defines a sealing volume in which a hydraulic binder or any other sealing means can be put in place. In this sealing volume extend the radial projections 27 and the annular projections 28.

Other forms of projections may be provided, in addition to or instead of the projections 27, 28 described above.

In the embodiments shown, the flange 20 is provided with a vertical plane of symmetry S, this plane containing the axis of rotation 25 of the winding drum 1.

So that the cheek 20 is reversible and can be used for both the right side and the left side of the boxes.

The guide wall 30 is extended, at its upper part, by a curved tab 32 projecting towards the inside of the box 7.

This curved tab 32 has a radius of curvature such that it is capable of coming opposite and bearing at least partially against the upper part of the internal face 15 of the gutter 9.

The lateral edges 33, 34 of the heel 22 are adapted to be housed in rails 35, 36 complementary which is provided with the gutter 9.

In the embodiments shown, these rails 35, 36 have a transverse U-shaped profile open towards the inside of the box 7.

In some embodiments, not shown, these rails are integral with the gutter, this gutter being for example extruded or molded.

In the embodiments shown, these rails 35, 36 are formed by profiles 37 reported against the lower longitudinal edges of the channel 9, for example by simply snapping eventually completed by gluing, welding or riveting.

 Starting from the lateral edge opposite the rails 35, 36, these profiles 37 comprise, on a substantially flat and horizontal base wall 38 - a first longitudinal edge 39 projecting vertically upwards, over a height h 1 - an intermediate wall 40 projecting vertically towards the top, on a height h2 greater than h1; - A wall 41 of rail bottom, projecting vertically upwardly over a height h3; - A high rail edge wall 42 disposed opposite a wall 43 of low rail edge.

The longitudinal edge 39 delimits with the intermediate wall 40 a width zone, measured along D2, less than or equal to the thickness of an insulation plate, for example fibragglo.

The intermediate wall 40 is pressed against the outer front face 10 of the box 7.

The transverse positioning of the cheek 20 relative to the trough 9 is obtained by - the complementary shape of the lateral edges 33,34 of the heel 22 and rails 35,36 defined by the profiles 37 attached to the trough 9; - The complementary shape of the guide wall 30 of the cheek and the inner face 15 of the trough 9; the complementary shape of the curved tab 32 and the upper part of the internal face 15 of the gutter 9.

The longitudinal positioning of the cheek 20 with respect to the trough 9 is obtained by the contact between the longitudinal bearing wall 29 of the cheek 20 and the corresponding transverse lateral face 13, 14 of the trough 9, this contact being obtained on a transverse support strip 44.

Such a structure facilitates the centering of the axis 25 of the winding drum 1.

If necessary, resilient means such as leaf springs may be provided in the rails 35, 36 of the trough 9, these elastic means reinforcing the maintenance in stable position of the underside of the box.

The heel 22 of the cheek 20 forms lateral support for the elements of the underside of the box 7.

The cheek 20 may be made of polymer material.

The central zone 24 optionally attached to this cheek 20 may be made of metal or of polymer material, identical or not to that of the body of the cheek 20.

When the gutter 9 is made of polystyrene, the cheek 20 may be provided with hooking projections coming into the walls of the gutter. The cheek 20 may also be provided with a detent means on the trough 9.

In some embodiments, the main part of the cheek 20 is material or rigidly assembled to the heel 22.

In other embodiments, the heel is removably mounted on the main part of the cheek.

We will now more specifically describe the slide holder associated with the cheek 20 of the shutter box.

In the embodiments shown, this slide holder 50 is of L-shaped profile and comprises a first portion 51 and a second portion 52, substantially perpendicular to each other.

The first part 51 is in the form of a flat plate provided with a free beveled end portion 53.

The second portion 52 is also in the form of a flat plate integrally formed or rigidly assembled to the first portion 51.

In the embodiments shown, the first part 51 of the slide holder 50 is intended to be inserted, after its association with a guide tulip 8, in a housing 54 provided for this purpose, in the upper part of the guide rails 4.

For example, the guide tulips 8 may comprise an upper portion 55 with double curvature connected to a base 56, this base being able to be assembled to the slide holder 50.

In the embodiments shown, this assembly is achieved by means of a pin 57 and a corresponding hole 58, the pin 57 projecting on a transverse face of the base 56, and the hole 58 being formed in the first portion 51 of the holder. slide 50.

Of course, the positions of the hole and the nipple can be reversed. Other means of assembly of the slide holder and the guide tulip 8 can be implemented.

This assembly can be reversible, as in the embodiment shown in FIG.

This assembly may, alternatively, be substantially definitive, for example by gluing, riveting, stapling, welding, or any other equivalent means, chosen in particular according to the materials used to make the tulip 8 and the slide holder 50. Also, in another embodiment, the tulip 8 and the slide holder 50 can be made in one piece.

In the embodiment shown in FIG. 3, the transverse face of the base 56 carrying the pin 57 is substantially flat and intended to come into contact with the corresponding transverse face of the first portion 51 of the slide holder 50.

The base assembly 56 / first part 51 of the slide holder 50 is intended to be introduced over a height H into the housing 54.

This height H is defined by the distance between the beveled lower free end 59 of the base 56 of a stop 60 disposed on this base 56.

In an alternative embodiment, not shown, said stop is disposed on the first portion 51 of the slide holder 50.

When the slide holder 50 and the tulip 8 are associated, their beveled lower end portions 53, 59 form a blade facilitating insertion into the housing 54.

If necessary, a wedge effect can be obtained, the base and / or the first portion 51 of the slide holder having an increasing thickness from their free end portion 53, 59 to their opposite end.

Alternatively or in combination, the housing 54 may have a larger section at the top than at the bottom.

Alternatively or in combination, the housing 54 may be provided with internal projections or spring blades or latching means.

Snap-fastening means or elastic tabs may also be provided on the base and / or the first part of the slide holder 50, to reinforce the holding of the tulip 8 / slide-holder assembly 50 in the housing 54.

If necessary, to reinforce this maintenance, a gluing or welding can be implemented.

In some embodiments, not shown, the assembly Tulip 8 / slide holder 50 is assembled directly at the bottom of the slideway 4, by screwing, riveting, bolting, stapling, welding or any other equivalent means.

The second portion 52 of the slide holder 50 is intended to be housed in a groove 61 formed in the heel 22 of the cheek 20. In the embodiment shown in Figure 3, the cheek 20 is provided with two grooves 61, symmetrical relative at the plane S, each groove 61 being limited by two lateral walls 62, 63, which are substantially vertical and facing one another and two walls 64, 65, substantially horizontal and facing each other .

The upper horizontal wall 64 is provided with a longitudinal rib 66 projecting into the groove 61 halfway thereof.

The width <B> 152, </ B> measured along D2, of the second portion 52 of the slide holder is substantially equal to the distance separating the lateral walls 62, 63 of the longitudinal projection 66.

So that the slide holder 50 can, in each groove 61, be placed relative to the heel 22 in two predetermined extreme positions. This arrangement allows a depth adjustment of the roller shutter box relative to the slideways, or reciprocally, slides relative to the box.

In the embodiment shown, this adjustment is of the two-position type, for each groove 61 of the cheek beads 22.

In other embodiments, not shown, one or both grooves are provided with more than one longitudinal projection 66, allowing adjustment between three or more positions.

In still other embodiments, one or both of the heel grooves are free of longitudinal projections 66 and the slide holder 50 can be inserted into the groove in any desired position.

The locking of the slide holder in this desired position can then be obtained for example by screwing it through a longitudinal slot formed in the upper wall 64 of the heel 22.

In some embodiments, not shown, the guide tulip 8 and the slide holder 50 are integral.

The symmetrical nature of the cheek as shown allows an indifferent assembly to the right or left of the box.

This arrangement also makes it possible, as shown in FIGS. 7a, 7b, 7c, to easily adjust the depth of the slide holder, whether the box is mounted with internal or external winding, or that the rolling shutter deck so forward or backward of the box.

Thus, the cheek shown in Figure 7a is mounted on a rolling shutter box whose deck 2 is rolled outwardly.

This same cheek can be mounted, as shown in Figure 7b and 7c, on a roller shutter box whose deck is rolled inwardly, the apron sliding close (Figure 7b) or away from the array table.

The sealing of a box provided with at least one adjustable sliding-gate cheek according to one embodiment is now described with reference to FIGS. 4 to 6.

The box 7 shown in these figures was set up in a reservation 80 of masonry.

The upper face 12 of the box 7 is pressed against the upper face of the reservation 80.

The longitudinal support walls 29 are pressed against the side walls 82 of the reservation 80.

In certain embodiments, not shown, the beam of the lintel allowing the transfer of load to the jambs or piers can be provided with such a reservation 80.

A sealing binder 81 filled the space between the outer faces of the cheeks and the side walls 82 of the reservation.

Depending on the layout of the building in which the shutter is to be put in place, it is possible, thanks to the cheeks just described, to adjust the position of the box with respect to an imposed position of the slides, or to adjust the position slides relative to an imposed position of box.

More generally, it is possible, by the use of the cheeks just described, to adjust in depth the position of the rails or slides relative to the box.

The double arrow of FIG. 8 illustrates the principle of such a depth adjustment, in the direction D2.

When a width adjustment of the position of the rails, in the direction D1, is desired, one of the following arrangements may for example be taken, alone or in combination - developing a set of sliding door, provided with seconds parts of different lengths L52; - cutting, in the direction D2, second portions 52 of sliding doors 50, until the desired length; - Implementation of transverse projections on the upper wall 64 of the heel 22, these projections, arranged in the direction D2, defining a plurality of successive stop positions for the insertion, along D1, of the second portions 52 in the grooves 61 of the heels of play.

In one mode of implementation, one of the two lateral cheeks of the box allows such adjustment of the position of the slides along D1, the other slide being in the fixed position.

In other embodiments, the two cheeks allow such an adjustment of the position of the slides following D1.

This width adjustment can be obtained in combination with the depth adjustment previously described.

The box cheeks for roller shutter that have just been described are inexpensive, can be installed indifferently to the right or left of a roller shutter box.
