Abstract

Electrical connector between internal and external cables consists of plate which forms a side wall of shutter housing and has at least one aperture for the external cable, a detachable inner cap with a hole for the internal cable and a fastening system for attaching the cap to the plate. Once fitted it forms a junction box for the connected ends of the external and internal cables. The electrical connector between internal (62) and external (75) cables consists of a plate which forms a side wall of the shutter housing and has at least one aperture (72) for the external cable, a detachable inner cap (51) with a hole (61) for the internal cable and a fastening system (60, 65) for attaching the cap to the plate. Once the cap is fitted to the plate it forms a junction box for the connected ends of the external and internal cables. The cap can be fastened to the housing plate by a screw, rivet, stapling, welding, clipping or a force fit. The plate can be made from a polymer material and it is fitted into a cavity of a component made from concrete, terracotta, polymer or metal alloy.

Description

The invention relates to the technical field of motorized roller shutters.

By "roller shutter" we mean here the aprons that can be unwound and rolled up, of the type formed by articulated blades, or even such as blinds, drapes, curtains, metal grilles, or the like.

The invention relates in particular, but not exclusively, to roller shutters whose aprons, when rolled up or unrolled, slide in two opposite lateral sides in slides fixed on either side of a opening.

Most often, these aprons are vertically erased by winding around a tree contained in a box placed above a bay, under or behind the lintel.

In some applications, such as swimming pool curtains, the erasure of the apron can be substantially horizontal.

When these aprons are formed by the assembly of articulated blades, these blades are most often made of wood, metal alloy or material polymer such as PVC.

Such aprons can have various functions such as in particular shutter, partial concealment, decoration, opening protection against bad weather or break-ins.

Such aprons can also be used for the creation of partitions temporary.

By "motorized roller shutters" is meant here installations comprising a housing called box, trunk or casing, delimiting a space in which the flap is wound or unwind around an axis driven by a motor online order.

The roller shutter boxes known in the prior art are of different kinds.

According to a first type of conventional implementation, these boxes comprise a tubular body produced by assembling profiles longitudinal in wood, polymer material or metal alloy, the ends of this tubular body being closed by end caps or function covers aesthetic.

Most often, this type of box is of square cross section or rectangular.

Positioned above the carpentry of a bay, between the level of the upper cross member of the frame frame and the level of the ceiling, these boxes are most often intended for winding the deck towards inside.

According to a second type of implementation, the boxes include a part in the general shape of gutter most often made of terracotta, hollow extruded brick, concrete, expanded polystyrene or other material polymer, or even in the form of an extruded alloy profile metallic.

In this second type of implementation, the final volume of the box is delimited by the installation, on the part in the form of gutter, of an under-face and side pieces.

The underside is most often made of polymer material, wood, or metal alloy.

Such gutter-shaped main room housings may be at least partly placed in a reservation made in the bay lintel to be fitted with a roller shutter.

The lower wall of the roller shutter boxes has an opening placed as the case may be, at the front edge or at the rear edge, this opening serving to passage of the apron.

To the right of the lateral ends of this opening abut the slides side of the apron guide.

The electrically controlled motor unit enabling the deck to be deployed in front of the bay or its erasure in the box is most often housed in the box, an electric cable being connected to the motor member and leaving the caisson.

When the cable is directly connected to the drive unit and is embedded in the masonry at its exit from the box, the work of revision or repair are made complex insofar as the assembly formed by the drive unit and the rolled up apron cannot be removed from the casing while being separated from the connection cable.

To solve this problem, document FR-A-2 775 729 proposes a set motorized shutter in which the motor power cable drive can be disconnected using a plug / socket type assembly arranged in the box.

Thus, in an embodiment described by this prior document, the cable power supply is connected to an outlet on a U-shaped frame, the motor being also integral with a piece called supporting cheek carrying a plug, a third piece to immobilize the supporting cheek in the U-shaped frame.

The device described in document FR-A-2 775 729 has numerous disadvantages.

First, as it is specified in this document, the blocking of the part insertable in U intended to immobilize the support cheek and therefore the motor drive must be done through the rear panel or the rear wall of the roller shutter box.

So that in this prior device, the quality of the electrical connection between the plug and the socket depends on the dimensioning of the box.

However, the dimensions of the box can be imposed for example by parameters related to the building, such as the possible dimension of the reservation in which the box is to be housed.

Second, the quality of the electrical connection described in the document FR-A-2 775 729 is also dependent on the possibility of an assembly precise of the three separate parts forming the module to be inserted in the box, which implies an important and expensive manufacturing control for these three rooms.

Thirdly, the electrical control of an assembly as described in the document FR-A-2 775 729 will be difficult for caissons at least in part placed in a reservation made in the lintel of a bay: in this previous assembly, the electrical connection is indeed placed in a narrow lateral space of the box.

Finally, in this prior device, the drive motor forms an element structural in one piece with the piece called cheek support, which can lead additional costs when the engine needs to be changed or when different wiring must be carried out and that the plugs and sockets do not include the number of terminals required for this new wiring.

The aforementioned drawbacks can be resolved by carrying out inside the box a simple electrical connection, by means of a connector such as by example a domino, on the one hand between an external main power cable the end of which is passed through the box, and on the other hand a portion of internal cable, one end of which is connected to the motor. However, the major drawback of this solution is that the electrical connection as well performed is exposed to dust and is not protected from moisture.

The object of the invention is therefore to propose a new connection solution electric for motorized roller shutter box, which overcomes the disadvantages aforementioned devices known in the prior art, and which moreover is little expensive and easy to implement.

• connecting means for fixing the cover on the internal face of the cheek, so that once mounted on the cheek the cover defines with the internal face of the cheek an internal electrical connection box provided with at least one through hole for the passage of an extreme part of the internal cable.

The hole in the cheek for the passage inside the box of the end of the internal cable can be through from the start or be provided to be returned crossing by being, for example, temporarily closed at the origin by a breakable or tear-off lid, for example the installer breaks or tears during the assembly phase of the box.

In a preferred embodiment of the invention, the through hole of the electrical connection box formed by the cheek and the cover is not exclusively made in the cover, but is delimited at the same time by the face inner cheek and through the hood. This feature allows advantageously by using an internal cable of sufficient diameter, to ensure simultaneously with the fixing of the cover on the internal face of the cheek, a tightening of the cable between the cheek and the hood, and thereby fix this cable at one point by compared to the cheek. The electrical connection which is thus produced has a greater safety compared to a cable which would have no point of fixation. In addition, this fixing of the cable does not require any operation. additional than that of fixing the hood to the cheek.

According to an additional characteristic of the invention, the through hole in the cheek for the passage of the external cable is made in the cheek area corresponding to the location of the cover, so that once the cover is attached on the cheek, this through hole opens directly inside the housing electrical connection formed by the cover with the internal face of the cheek.

We first refer to Figure 1.

The motorized roller shutter shown in Figure 1 includes a motor member mounted on the axis of a winding drum 1.

In the embodiments shown, this motor member is coaxial with take-up drum 1.

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

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 position extreme unwound, can be at least partly wrapped around the drum 1, the rotation of this drum 1 being obtained by the drive motor member electric.

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

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

As will be clear to those skilled in the art, the invention can be put used for roller shutters whose erasure does not take place in a substantially vertical plane, the axis of the winding drum not being either necessarily horizontal.

The motorized roller shutters described in detail below as examples of realizations will be of the vertical erasure type, the axis of the drum winding being horizontal and placed in the upper part of a bay such as by example a door, a window or a 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 according to longitudinal articulation axes.

These articulated blades 3 can in particular be made of wood, of a metal alloy or in polymeric material such as PVC.

The lateral ends of the blades 3 of the deck 2 slide in slides lateral guide 4.

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

Apron 2 includes two end blades, the upper end blade 3a being connected to the winding drum 1.

In the embodiment shown in Figure 1, this end blade 3a is connected to the winding drum 1 by two flexible bands 5.

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

The drive member and the winding drum 1 are placed in a box 7 whose lower wall has an opening allowing the passage of the apron 2.

To the right of the lateral ends of this opening abut the slides lateral guide 4 of the deck 2.

Guide pieces 8 called tulips, of a type known per se, are placed in extreme upper part of the lateral guide rails 4.

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

This underside can be made of polymer material, wood, alloy metallic, or any equivalent material.

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

Subsequently, this part 9 will be called simply "gutter".

This gutter 9 is of generally parallelepipedic envelope and comprises a front external face 10 and a rear external face 11 substantially vertical, a substantially horizontal upper external face 12 and two lateral faces 13, 14 substantially transverse.

This gutter 9 has, in cross section, an internal face 15 in the form of U open downwards, this U-shaped profile opening onto the two lateral faces 13, 14.

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

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

When the gutter 9 is made of polymer material, cavities can be arranged in the thickness of its walls, these cavities improving the insulation phonic or thermal, these cavities reducing the weight of the box compared to a box with solid walls.

Such cavities can for example come from the shape of the die extrusion, or in the shape of the mold.

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

For example, a flexible waterproof membrane can be glued or stapled to the internal face 15 of the gutter 9.

A cork board can also be placed opposite the internal face 15 of the gutter 9.

The gutter 9 can be obtained by molding large U-shaped profiles length and cutting of this profile into elements of desired lengths.

The final volume of the box 7 is delimited by the installation, on the piece in shape of gutter 9, an underside and two side pieces.

Other embodiments of the box can be envisaged.

Thus, for example, the box can include a piece in the form of a gutter whose opening is placed towards the front of the box, a protective element removable forming a cover which closes this gutter.

In other embodiments, not shown, the box comprises a tubular body produced by assembling longitudinal wooden profiles, polymer material or metal alloy, the ends of which are closed by side pieces.

The upper part of the internal face 15 of the gutter 9 can be curved and in an arc, as in the embodiment shown.

In other embodiments, not shown, the upper part of this internal face 15 is substantially planar, or else in an arc of an ellipse.

In the embodiments shown, the box has two side pieces substantially identical, both of which may be provided with one or two connection boxes.

In other embodiments, not shown, only one of the parts side has one or two connection boxes, the other side piece being for example of standard type.

In the prior art, the lateral parts of the roller shutter boxes are called, depending on their configuration, shutter cover, cover, cover protection, flange, consoles, or end cap.

The terms "shutter cover", "protective cover", "end caps" or "Cover" are generally used when the side pieces have essentially or only a wall function, to be if necessary aesthetic.

Conversely, the terms “console”, “flange” are used to designate side pieces which directly or indirectly support the axis of the drum winding.

In order to simplify, in the following description, the side pieces of the box will be called simply "cheeks".

Indeed, in the embodiments shown, these cheeks form a wall of closing of the box 7 and moreover have a drum axis support function winding 1.

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

In the embodiments shown, the box is intended to be at least in part placed in a masonry reserve, so that the cheeks are sealed in this reservation using a hydraulic binder. In these achievements, the cheeks not being visible do not have a cover function aesthetic.

Conversely, in other embodiments, not shown, the external faces cheeks of the box are at least partly visible and have a function of aesthetic side cover for the box.

A motorized roller shutter box cheek will now be described in detail with reference to Figures 2 and following.

The cheek 20 shown in Figure 2 has a main wall 21 and a heel lower 22 substantially horizontal.

The lower heel 22 can be attached or come integrally with the wall main 21.

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

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

The assembly of this disc on the main wall 21 can be obtained by snap-fastening, screwing, welding or any other equivalent means of assembly.

In other embodiments, not shown, the main wall of the cheek is in one piece.

The external face of the transverse part 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 protrusions.

These projections extend perpendicular to the external face of the section transverse 23.

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

These projections 27, 28 may reinforce, as will appear later, the taking of the binder for sealing the box 7 in a reservation.

The main wall 21 of the cheek 20 comprises, on its lateral edge, a wall longitudinal support 29.

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

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

This internal face 31 of the guide wall 30 is intended to come opposite and resting at least partially against the internal face 15 of the gutter 9 when the cheek 20 is in place on the gutter 9.

The transverse part 23 of the cheek 20 is set back towards the inside of the box 7 with respect to the longitudinal support wall 29.

This shrinkage, of axial dimension substantially equal to the width of the wall of guide 30, defined a sealing volume in which a hydraulic binder or any other sealing means may be used.

In this sealing volume extend the radial projections 27 and the projections ring finger 28.

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

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

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

The guide wall 30 is extended, in its upper part, by a tab curve 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 into look and in support 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 capable of being housed in rails 35, 36 complementary with which the gutter 9 is provided.

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

In some embodiments, not shown, these rails have come in one piece with the gutter, this gutter being for example extruded.

In the embodiments shown, these rails 35, 36 are formed by profiles 37 fitted against the lower longitudinal edges of the gutter 9, by example by simple click-in optionally completed by gluing, welding or riveting.

• une paroi 41 de fond de rail, en saillie verticale vers le haut sur une hauteur h3 ;
• une paroi 42 de bord haut de rail, disposée en regard d'une paroi 43 de bord bas de rail.

Starting from the lateral edge opposite the rails 35, 36, these sections 37 comprise, on a base wall 38 substantially flat and horizontal:

• a first longitudinal edge 39 projecting vertically upwards, over a height h1
• an intermediate wall 40 projecting vertically upwards, over a height h2 greater than h1;
• a wall 41 of the rail bottom, projecting vertically upwards over a height h3;
• a wall 42 of the top edge of the rail, disposed opposite a wall 43 of the bottom edge of the rail.

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

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

The transverse positioning of the cheek 20 relative to the gutter 9 is obtained by:

• the complementary shape of the lateral edges 33,34 of the heel 22 and of the rails 35,36 defined by the profiles 37 attached to the gutter 9;
• the complementary shape of the guide wall 30 of the cheek and of the internal face 15 of the gutter 9;
• the complementary shape of the curved tab 32 and of the upper part of the internal face 15 of the gutter 9.

The longitudinal positioning of the cheek 20 relative to the gutter 9 is obtained by the contact between the longitudinal support wall 29 of the cheek 20 and the corresponding transverse lateral face 13,14 of the gutter 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, elastic means such as leaf springs can be provided in the rails 35, 36 of the gutter 9, these elastic means strengthening the stable position of the underside of the box.

The heel 22 of the cheek 20 forms lateral support for the elements of the under face of the housing 7.

The cheek 20 can be made of polymer material.

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

When the gutter 9 is made of polystyrene, the cheek 20 can be provided hooking projections which sink into the walls of the gutter.

The cheek 20 can also be provided with latching means on the gutter 9.

We now describe more specifically the connection box associated with the cheek 20 of the motorized roller shutter box.

In the embodiments corresponding to Figures 1 to 5, this connection box 50 comprises a cover 51 attached by screwing onto the main wall 21 of the plays 20.

This cover 51 comprises a bottom wall 52 and an annular skirt 53.

A pillar 54 provided with an axial through hole 55 extends perpendicular to the bottom wall 52.

This pillar 54 is of outer envelope in truncated cone flaring towards the bottom wall 52.

The free end 56 of this pillar 54 is substantially flat and perpendicular to the axis 57 of the through hole 55.

This free end portion 56 is set back, towards the inside of the cover 51, relative to the free annular edge 58 of the skirt 53.

In its free end, the skirt 53 has an external thinning defining an annular shoulder 59 substantially perpendicular to the axis 57 through hole 55.

The end of the skirt 53 is tapered, so that the cover 51 can be put in place in an annular groove 60 formed on the internal face of the part transverse 23 of cheek 20.

The cover 51 also has at least one groove on the free annular edge. radial 61 intended for the passage of an end portion of one or more portions cables 62 internal to the box 7, these cables being in the modes of realization considered, connected directly to the driving organ of the drum winding 1.

Around this radial groove 61, the skirt 53 of the cover 51 is provided with a excess material thickness 63.

The protective cover 51 is placed on the cheek 20 by insertion of the end of the skirt 53 in the groove 60 of the cheek 20.

By this positioning, the free end 56 of the pillar 54 of the cover 51 abuts against the corresponding free end portion 64 of a protruding stud 65 perpendicular to the internal face of the transverse part 23 of cheek 20.

This stud 65 is provided with a blind hole 66 arranged in the extension of that of the axial hole passing through 55 of the cover 51.

This stud 65 is of outer envelope in a truncated cone flaring towards the main wall of the cheek 20.

In the embodiments shown, the cover 51 is a part which, groove 61 placed apart, is of revolution around axis 57; the stud 65 being, likewise, a part of revolution around an axis 67.

In other embodiments, the cover 51 and / or the pad 65 are not symmetry of revolution.

A screw 68 passing through the through hole 55 of the cover 51 and its extension in the blind hole 66 of the cheek 20 allows the hood 51 to be blocked on the cheek 20 in a predefined position.

In this screwed position, the cable or cables 62 internal to the box 7 are held in place in the radial groove (s) 61 by slight crushing of these cables or their sheath.

In the embodiment shown, hooking projections 69 reinforcing this clamping are arranged on the wall of the radial groove 61.

Between the groove 61 and the base of the stud 65, the internal face of the cheek 20 defines a substantially planar wall 70 forming the bottom of the connection box 50.

Around the groove 60, the internal face of the cheek 20 extends in a plane offset from the wall 70 at the bottom of the connection box 50. The cheek 20 thus presents on the internal face a slight hollow, the annular edge 71 of which forms bearing surface for the shoulder 59 of the cover 51. This characteristic allows to reinforce the tightness (humidity and dust) of the connection box electric formed by the hood and the internal face of the cheek.

The cheek 20 is provided with a through hole or channel 72 opening at the right of the wall 70, between the groove 60 and the base of the stud 65. In another variant of the invention, the hole or channel 72 could be provided outside the area of the cheek corresponding to the wall 70 (bottom of the connection box). In this case, it should be provided in the connection box formed by the cover and the cheek, an additional opening for the passage, inside the connection box from the end of the external cable. Also, in another variant, the hole or channel 72 could be originally closed by a breakable seal or tear. In this case, during assembly of the box, the installer returns the hole or channel 72 passing through by tearing or breaking the cover.

The through channel 72 is defined by a projecting tube 73 with an internal wall 74 in shape of a truncated cone that flares from the inner face to the face cheek external 20.

This flared shape allows the cables 75 or their sheath to be trapped in the protruding tube 73.

The through channel 72 defined by the protruding tube 73 extends substantially perpendicular to the mean plane of the transverse part 23.

The dimension of the protruding tube 73, measured along D1, is slightly smaller to the width of the guide wall 30.

The connection box formed by the cover 51 placed on the cheek 20 defined a volume V in which the cables 75, external to the box, can be connected in the desired way, to cables 62, internal to the box.

For simplification, this connection, which can be achieved by any means known per se, has not been shown in the figures.

This connection is protected from humidity, dust or other bodies foreigners who may be in the central volume of the box 7.

To strengthen this protection, as shown, the internal face of the cheek 20 can be provided with a groove 76 for receiving cables 62 or their sheath, this groove 76 and the radial groove 61 of the cover 51 defining, when compared, a conduit for the entry, in the connection box 50, of the internal cables 62.

We will now describe another embodiment of the connection box, in reference to Figures 6 and 7.

In this embodiment, the cover 51a does not have an internal pillar with a hole axial.

The cover 51a comprises a bottom wall 77 in the form of a disc and a skirt annular 78 cylindrical projecting from this bottom wall 77.

This cover 51a is intended to be screwed onto the cheek 20 by means of two screws side 79 or any other equivalent means, the screwing of the cover 51a coming tighten the cables 62 in a groove 76 similar to that described above.

When the cover 51 a is screwed onto the cheek 20, the lateral edge of its bottom wall 77 is in abutment against the internal transverse face of the cheek 20.

So that, in the embodiment of Figures 6 and 7, the internal volume of the connection box does not encroach on the internal volume of the box 7.

In the embodiments shown, two connection boxes can be mounted on each cheek 20, these housings being substantially symmetrical about the S plane.

This arrangement reinforces the symmetrical character of the cheek, for mounting indifferent to the right or to the left of the box.

This arrangement also allows, as shown in FIGS. 11a, 11b, 11c, to easily make the electrical connection, that the box is mounted with internal or external winding, or the roller shutter curtain comes out forward or backward of the housing.

Thus, the cheek shown in Figure 11a is mounted on a shutter box roller whose deck 2 is winding outwards.

This same cheek can be mounted, as shown in Figure 11b and 11c, on a roller shutter box, the apron of which is inwardly wound, the sliding apron near (figure 11 b) or at a distance from the bay table.

In these three cases, the entry of cables 75 external to the box may be chosen in the most convenient way, near the front panel or the rear face of the box, to the right or to the left of this box.

When only one of the two protruding tubes 73 forming the through holes 72 is used, a snap-on, welded or glued cover, or an attached plug may be placed in line with the unused through hole 72, in particular so as to avoid the entry of hydraulic binder when sealing the box.

As a variant, the through holes 72 can be provided with a sealing veil partially or completely the protruding tube 73, this veil having to be perforated during introduction of cables 75.

According to another variant, the protruding tubes are provided with legs or lips internal hoses forming non-return valve.

We will now describe the sealing of a box provided with at least one cheek connection box, according to one embodiment, with reference to the figures 8,9,10 and 12.

The box 7 shown in these figures has been put in place 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 reservation 80.

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

The sealing binder 81 of the cheek 20 in the reservation 80 cannot substantially not pass through the through hole 72 for entering cables 75.

In fact, when the longitudinal support walls 29 are pressed against the side walls 82 of the reservation 80, these side walls 82 of the reservation 80 are placed a short distance from the free edge 83 of the projecting tube 73.

The length of the gutter 9 can be adjusted for this purpose.

Furthermore, as has been said above, the internal wall 74 of the projecting tube 73 is in the form of a truncated cone, the diameter of the cable sheath 75 being able to be such that this sheath is forced into this projecting tube 73.

The box cheeks for motorized roller shutters which have just been described are inexpensive, can be installed either on the right or left of a roller shutter box.

They allow the passage of supply and / or control wiring the shutter winding motor, these cables can be modified or controlled by opening the main central volume of the box without dismantling cheeks which can thus be permanently sealed, these cheeks being able moreover form substantially waterproof walls for the box.

The cheeks of roller shutter boxes which have just been described may well understood to be used for non-motorized roller shutter boxes.

In some applications, for example, at least one through channel 72 of a cheek 20 can be used for the passage of cables of an installation of heating of the interior of the box, or cables of a radio receiver for a remote control for example of the drive motor of the shutter curtain rolling.

In the particular embodiment which has been described with reference to attached figures, the roller shutter box is sealed in the masonry, and is commonly called a tunnel safe. This particular area is not limiting of the invention. The invention advantageously applies to any type of known roller shutter box, and can for example be applied in the field of unsealed boxes, such as boxes used in renovations and mounted on interior joinery, or exterior boxes.
