Description

The invention relates to a flap shutter motor assembly and to a method of installing such a motorization assembly.

In the field of home automation it is known to use a set of shutter damper motor to attach to a lintel so as to automate the closing and opening of one or more leaves.

Numerous motorization solutions make it possible to manage the opening and closing movements of flaps. It is known to use either a single engine or a single engine for a set of two leaves.

We already know the patent application EP-A1-2746513 which describes a flap shutter motor assembly. The motor assembly comprises a motor module monoblock equipped with a motor and transmission means, configured to be connected to a movable arm integral with a leaf. The motor assembly includes a bracket, to facilitate the installation of the motorization module to a lintel. In the assembled configuration of the engine module to the lintel, the bracket bears against a vertical amount of an opening capped by the lintel and is fixed on the vertical upright, the engine module being mounted on a portion of the square extending in a plane parallel to the plane of the lintel. Thus, the fixing bracket, once fixed under the lintel by an installer, allows to position and accommodate a first end of the motorization module. A second end of the engine module can then be attached to the lintel by the installer by holding the engine module with one hand.

If this device and mounting method facilitates installation, the motor assembly remains heavy and expensive, as the bracket is expensive to manufacture. Indeed, the anchoring point of the motor assembly being deported with respect to the forces received at an axis of rotation of the arm, it is necessary to strengthen the parts so that they can withstand the forces suffered at the level of of the axis of rotation of the arm, which increases their cost.

It is these drawbacks that the invention intends to remedy more particularly by proposing a more economical motor assembly that is easy to install and resistant.

In this regard, the present invention aims, in a first aspect, a shutter damper motor assembly comprising a first electromechanical module, the first electromechanical module comprising a first electric motor and an electronic control unit, the motor assembly comprising a frame for attachment to an architectural element of an opening in a building, the frame including fixing holes so as to secure the frame to the architectural element.

According to the invention, the motorization assembly also comprises at least one slideway extending along a longitudinal axis of the chassis and assembly elements, the assembly elements being arranged to cooperate with the slideway, so as to guide the electromechanical module in translation relative to the chassis and then to secure the electromechanical module to the chassis, during assembly of the electromechanical module to the chassis.

Thus, it is possible to install the frame alone at the architectural element, then report the electromechanical module on the frame and position it adequately with respect to the architectural element before fixing.

According to an advantageous characteristic of the invention, the motorization assembly comprises a transmission shaft, rotatable about an axis, the transmission shaft being connected, on the one hand, to the first motor and, on the other hand, an arm intended to be secured to a leaf and in that the connecting elements are distributed around the axis of the transmission shaft.

According to an advantageous characteristic, the housing comprises at least one abutment brought into contact with the screw during assembly of the motor assembly to the frame

Advantageously, the stop is deformable under the application of a tightening torque applied between the screw and the clamping nut.

Thus, the screws being manually tightened against the abutments, the clamping makes it possible to control a clearance between the casing and the heads of the fixing screws, making it possible to facilitate the sliding of the casing along the slideways. A greater tightening causes a translation of the screws towards the housing and crushing or deformation of the stops. The screws then come into contact with the slideways of the frame, in particular with the walls of the slideways, which locks the position of the module by clamping, thus making it possible to block the module in rotation and in translation relative to the frame.

According to an advantageous characteristic, the slideway comprises at least one insertion zone configured to allow the insertion of a part of the assembly elements inside the slideway during the assembly of the motorization assembly to the frame .

According to an advantageous characteristic, the frame comprises a positioning stop of the electromechanical module relative to the frame.

The Figures 1 and 2 show a home automation system 100 flap installed at an opening 2 of a building 3, for example an opening with a window not shown. The installation comprises a motor assembly 1 attached to a lintel 4, above the opening 2. The opening 2 is equipped with a flap 5 consisting of two leaves or leaves 5a and 5b pivotable on hinges 6a , 6b so as to cover the opening 2 or to leave it uncovered, as shown in this figure. The motor assembly 1 comprises a finishing cap 10 covering part of the various components of the motor assembly 1. The motor assembly 1 thus controls a shutter installation with a main leaf 5a comprising a cover blade 7 or cover and a secondary wing 5b. The main leaf 5a must be driven first at the opening and last at the closing to ensure that the cover blade 7 is good cover the secondary leaf 5b.

The motor assembly 1 comprises a first electromechanical module M1 provided with a first electric motor MA and an electronic control unit 20, a second mechanical module M2 provided with a second electric motor MB. The electronic control unit unit 20 is connected to the two motors MA, MB. Each module M1, M2 also comprises mechanical transmission means 8a, 8b, in particular gabled transmission means, for transmitting the movements respectively provided by the motors MA, MB to the leaves 5a, 5b. Arms 8a, 8b connect the transmission means 7a, 7b to the leaves 5a, 5b to transmit the rotational movement of the motor MA, MB corresponding to a movement of the leaf 5a, 5b around its hinges 6a, 6b.

Upon receipt of a shutter movement control command, the electronic control unit 20 controls the activation of the two motors MA, MB in a sequence comprising a time shift between the activation of the priority motor MA and the secondary motor. MB: during an opening command of the shutter 5, the priority motor MA is the motor activated first, the secondary motor MB being activated with a time offset To with respect to the secondary motor MB, while on closing, the priority motor MA is activated second, with a time offset Tf relative to the secondary motor MB, the offsets at the opening and closing being equal or different.

Preferably, the electromechanical module M1 is associated with the main leaf 5a and the mechanical module M2 is associated with the secondary leaf 5b. In a case of reverse mounting (the priority motor MA being associated with the control of the secondary leaf 5b, the secondary motor MB being respectively associated with the main leaf, 5a), it is then necessary to invert the piloting sequence, that is, to say, to reverse the priorities associated with both engines. This priority inversion can be configured and stored in a memory (not shown) of the electronic control unit 20.

In the case of the motorization of a single flap leaf, the motor assembly 1 comprises an electromechanical module M1 comprising an electric motor MA and an electronic control unit 20.

The motor assembly 1 according to the invention, in particular the electronic control unit 20, comprises hardware and / or software means governing the control of the MA, MB motors. The software means include computer programs.

The electronic control unit, represented at figure 3 is powered on the commercial electricity network, for example 230V AC or on another energy source such as a battery and / or a solar panel. The electronic unit 20 comprises an electronic card 30 on which are implanted the electronic control components of the two motors, in particular a microprocessor 31 comprising information inputs and outputs intended for controlling the MA, MB motors, a receiver 21, in particular like radio frequency, for receiving control commands from a remote control point 110, in particular a radio remote control or a wired remote control connected to the control unit 20, a human-machine interface comprising a digital display 22 , simple control buttons (opening, closing, stop - alternating or sequential - programming) 23 and / or one or more LEDs 24. The human-machine interface is optionally accessible at the time of installation, but is no longer (or with difficulty) once the finishing cap 10 of the motor assembly 1 is positioned on the modules M1, M2.

Advantageously, the electronic control unit 20 further comprises means (not shown) for detecting an abutment force (by measurement of engine torque, torque variation or under-speed) and / or counting means. position.

The buttons 23 can be used for the manual control of the motors MA, MB and the pairing or association between the electronic control unit 20 and the remote control point 110.

The motor assembly 1 also comprises a frame 40, shown in FIGS. Figures 4 and 5 , comprising in a first embodiment two independent frame members 40a, 40b, which can be fixed to the lintel of the opening 2. These frame members 40a, 40b comprise fixing elements on which the mechanical and electromechanical M1 modules are fixed. M2. The frame members 40a, 40b are preferably identical, only one will be described later.

The frame member 40a shown at figure 4 is a metal support, in the form of a plate, preferably one-piece, comprising a flat base 42 intended to bear against the lintel 4 and an opposite face 43 provided with slideways 45, 46, 47.

The frame member 40a includes fixing holes 51, 52, which are for the passage of fastening screws (not shown) for attaching the frame member 40a to the lintel 4. The mounting holes are located at a ZF1 fixing area.

The slides 45, 46, 47 serve to guide and maintain a module M1 or M2 of the motor assembly 1 on the frame member 40a when the latter is fixed in position to the lintel. The frame member 40a thus comprises a central slide 46 and two parallel lateral rails 45, 47.

• d'une paroi de fond 45f, 46f, 47f réalisée notamment par la plaque formant support de l'élément de châssis 40a,
• de parois latérales 45z, 46z, 47z s'étendant perpendiculairement à la face opposée 43 de l'élément de châssis 40a,
• de parois de recouvrement 45y, 46y, 47y s'étendant perpendiculairement aux parois latérales, en direction l'une de l'autre de sorte à refermer partiellement la glissière 45, 46, 47.

The slides 45, 46, 47 are open at their two longitudinal ends, but they could also be closed on one of their ends, for example by an additional piece 55. They extend along the axis of greater length or longitudinal axis X of the frame member 40a. The slides 45, 46, 47, on the model of the slide 45, form rails whose largest section l45 can accommodate a screw head 65t. Each slideway 45, 46, 47 consists of:

• a bottom wall 45f, 46f, 47f made in particular by the support plate of the frame member 40a,
• sidewalls 45z, 46z, 47z extending perpendicular to the opposite face 43 of the frame member 40a,
• covering walls 45y, 46y, 47y extending perpendicularly to the side walls, towards each other so as to partially close the slideway 45, 46, 47.

The various walls 45f, 45z, 45y of the slide 45 thus form a U-rail slightly closed on itself, leaving free a longitudinal opening, between the covering walls 45y, whose width i45 is less than the width l45 of the rail formed by the slide 45 and therefore lower than said screw head 65t. The slides 46 and 47 are constructed substantially on the same model as the slideway 45. The lateral slides 45, 47 each further comprise a wall 48, 49 extending in the extension of one of the side walls, on the edges of the frame 40. These walls 48, 49 form a guide for the mechanical or electromechanical module to be mounted on the frame member.

The motor assembly 1, in particular each electromechanical module M1 and mechanical M2, comprises assembly elements 64 of the module to the frame member 40a. These connecting elements 64 are arranged to cooperate with the longitudinal rails 45, 46, 47 of the frame member 40a and adapted to secure the electromechanical module M1 or mechanical M2 to the corresponding frame member 40.

These connecting elements comprise the screws 65, 66, 67 whose heads 65t, 66t, 67t can slide in the slideways, these being fixed on the module to be mounted on the frame member, as shown in FIG. figure 5 .

According to a second embodiment shown on the figure 5 , chassis 40 is a one-piece chassis, custom-built for installation. The length of the chassis 40 is therefore adapted to the width of the opening 2. The two electromechanical modules M1 and M2 are mechanically installed independently on the chassis 40.

The frame 40 comprises a set of three longitudinal slides 45, 46, 47 similar to those described above. These slides may extend over the entire opposite face 43 of the frame.

Fixing holes 51, 52 arranged to allow the fixing of the frame 40 to the lintel 4 are located in fixing areas ZF1, ZF2 at each end of the frame 40.

Insertion areas 45j, 46j, 47j may be provided near the mounting holes of the frame to the lintel. In the example shown in figure 6 these insertion zones 45j, 46j, 47j correspond to recesses in the covering walls 45z, 46z, 47z of the slides 45, 46, 47, allowing access to the rail. In other words, the opening width j45, j46, j47 of the rail formed by the slideway 45, 46, 47 in the respective insertion zones 45j, 46j, 47j is greater than the opening width 145, i46, i47 on the remainder of the slideway 45, 46, 47.

Advantageously, these insertion zones 45j, 46j, 47j are shifted at least two by two in the longitudinal direction along the X axis.

Such insertions zones could also be provided on the frame members 40a, 40b of the first embodiment. However, they are particularly interesting in the second embodiment insofar as the connecting elements 64 of the modules M1, M2 can not be introduced by one or other of the longitudinal ends of the slides 45, 46, 47. once the frame is fixed to the lintel 4. Alternatively, the assembly elements 64 of the modules M1 and M2 are inserted into the slides 45, 46, 47 by the free ends thereof before mounting and fixing the frame 40 to the lintel. The assembly elements 64 of the motor assembly 1 comprise the screws 65, 66, 67 whose heads 65t, 66t, 67t can slide in the slideways, these being fixed on the module to be mounted on the frame 40, equivalent to the first embodiment. The degree of freedom in translation of the modules M1, M2 before their blocking makes it possible to fix the frame 40 to the lintel at each fixing zone ZF1, ZF2. These zones are covered by the modules during a positioning and fixing step by blocking of the modules M1, M2 to the zones ZF1, ZF2.

In an alternative embodiment not shown, the slides 45, 46, 47 are present only on an end portion of the frame 40, which allows to introduce the modules by the free end of a slide located in the direction of the central part of the chassis 40.

• E106 : installation du châssis 40 au niveau d'un élément architectural 4 d'une ouverture 2 d'un bâtiment 3,
• E107 : fixation du châssis 40 en une première zone de fixation ZF1
• E108 : positionnement d'un module électromécanique M1 ou mécanique M2 par glissement le long d'au moins une glissière 45, 46, 47,
• E109 : fixation du module M1, M2 par blocage en translation par rapport à la glissière 45, 46, 47.

The installation of the motor assembly 1 follows the following process steps:

• E106: installation of the frame 40 at the level of an architectural element 4 of an opening 2 of a building 3,
• E107: attachment of the frame 40 to a first fixing area ZF1
• E108: positioning of an electromechanical module M1 or mechanical M2 by sliding along at least one slideway 45, 46, 47,
• E109: fixing the module M1, M2 by translation locking relative to the slideway 45, 46, 47.

The positioning and fixing steps preferably take place at the right of the first fixing zone ZF1, the first fixing area of the frame 40 then being covered by a housing 60 of the electromechanical module M1 or mechanical module M2.

Steps E108 and E109 are renewed for a second module, once the frame 40 is fixed in a second fixing zone ZF2.

Once fixed, the frame 40 or the frame members 40a, 40b are locked in rotation and in translation, thus making it possible to withstand the torques used during the transmission of the mechanical force between the motors MA, MB and the leaves flaps 5a, 5b flaps 5.

In the absence of insertion areas, a module M1, M2 can be inserted laterally, in other words horizontally reported, by an open end of the slideways and positioned at the appropriate location relative to the frame 40 by sliding along the slideways. In this case, the assembly can follow the following steps in the following order: identification of the fixing holes 51, 52 of the frame 40 by using the frame alone, drilling, placement of the modules M1, M2 with respect to the slides 45, 46, 47, offset relative to the fixing holes 51, 52, fixing the frame 40 supporting the modules M1, M2 to the lintel 4, positioning the modules to the right of the fixing zones ZF1, ZF2, by sliding along the slides blocking modules in position.

In the presence of insertion zones, a module M1, M2 may first be vertically connected with respect to a frame part or via insertion zones in the slideways, in particular by inserting the assembly elements in these insertion areas then in the slides. It is then positioned at the appropriate location by sliding along the slides. Thus, the method comprises an intermediate step of insertion of a mechanical or electromechanical module M1, M2 into the slideway 45, 46, 47, in particular by using an insertion zone of the frame 40 or the free ends of the slides 45, 46. 47. This intermediate step can take place before the step E107 for fixing the frame 40 to the lintel 4 or after it.

The Figures 6 to 9 schematically detail part of an electromechanical or mechanical module. The following description is similar for both modules, only one will be described with reference to Figures 6 to 9

The module M1 comprises a housing 60 supporting the motor MA, the transmission means 8a and the arm 9a. The housing 60 may be in several parts assembled to each other by appropriate fastening means 63. The housing also supports an output shaft 70 of the transmission means 8a in rotation about an axis X70. The arm 9 is mounted on this shaft 70 by means of a washer 71 and a bolt 72. The face of the housing supporting the arm 9 is called high 62 of the housing while the opposite is called base 61 of the housing.

The housing 60 also supports the connecting elements 64. These connecting elements 64 comprise at least three fastening screws 65, 66, 67, offset relative to one another in the length and width of the housing 60.

Before the first installation of the electromechanical module M1 on the chassis 40, the module is placed so that the arm is downward, the base 61 of the housing facing the slideways 45, 46, 47. The screws 65, 66, 67 are clamped manually bearing on stops or stops 120, 121. This first clamping makes it possible to control a clearance between the housing 60 and the heads 65t, 66t, 67t of the fixing screws 65, 66, 67. The stops 120, 121 are provided on either side of the fastening screws in a longitudinal direction along the axis X of the frame or module and have a width less than the width i45, i46, i47 of the longitudinal opening of the rails formed by the slides 45 , 46, 47. As a result, they do not block the sliding of the module in the slideway. The stops 120, 121 are preferably formed integrally with the housing. The stops form a spacing between the head 65t, 66t, 67t of screw and the base 61 of the housing which is slightly greater than the thickness of the material forming the slideway 45, 46, 47, in particular the thickness of the material of the covering walls. 45z, 46z, 47z.

When sliding the module M1, M2 along the slides 45, 46, 47 of the frame 40, the screws 65, 66, 67 are angularly locked by the hexagonal shape of their head 65t, 66t, 67t and bear against the housing 60, in particular bear on the stops 120, 121 of the housing 60. The base 61 of the housing 60 thus moves in support on the outside of the slideways, because of the spacing provided by the stops 120, 121, when the module M1, M2 slides relative to the frame 40.

These fixing screws 65, 66, 67 pass through the module M1, M2 and can therefore be clamped by the top 62 of the housing supporting the arm 9a, for example by means of nuts (or socket nuts) for clamping 75, 76 , 77 correspondents. During installation, the mechanical module M1 or M2 slides relative to the frame 40 and comes into contact with the abutment 53 or the abutment stop 55. The nuts 75, 76, 77 are then tightened. A large tightening torque causes a translation of the screws in the direction of the housing and crushing or deformation of the stops 120, 121, in particular of the material forming the stops 120, 121. The screws then come into contact with the slideways 45, 46 respectively. , 47 of the chassis 40, in particular with the walls 45y, 46y, 47y of the slideways, which locks the position of the module M1, M2 by clamping, thus making it possible to block the module M1, M2 in rotation and in translation relative to the chassis 40 .

The connecting elements comprising the screws 65, 66, 67 and clamping nuts 75, 76, 77 are distributed around the transmission shaft 70, so as to also distribute the assembly points of the module M1, M2 to the right of the ZF1, ZF2 fixing zone of the chassis 40.

The main forces during operation of the motor assembly 1 are at the level of the transmission means 8a, 8b, in particular at the axis X70 of the transmission shaft. These forces can occur due to forces applied to at least one of the leaves, in particular due to gusts of wind, particularly when the flap is in position intermediate between the fully open position and the fully closed position of the wings, or an attempt to intrude when the flap is closed. Now the housing 60 supporting these transmission means 8a, 8b is assembled at the fixing zone ZF1 or ZF2 of the frame 40 or the frame members 40a, 40b to the lintel 4. Thus, the recovery of the forces of the set of motor 1 at the lintel level is located at the ZF1, ZF2 fixing zone at the lintel, which ensures excellent performance and durability of the motor assembly 1.

An abutment piece 55, also called a grommet stop, can be inserted at the end of the frame. This abutment piece comprises in particular a cable gland 56, and allows to reserve a space for the passage of a power cable (not shown) in the chute 56 between the module and the end of the lintel 4 above of the opening 2. It also forms a stop 53 for the module. This abutment piece can be inserted and held by friction on the frame, in particular by being itself inserted into the end of the slides 45, 46, 47 or clipped onto the frame via a recess 57 provided for in FIG. this effect in the chassis. Alternatively, a stop 53 'for the module is provided by a deformation of the frame 40 or the folding of a tab obtained by partial cutting of the frame 40.

A specific embodiment of an electromechanical module M1 or mechanical M2 is detailed in figures 11 and 12 . For simplicity, reference will be made to the mechanical module M2, but the description would be similar for the electromechanical module M1.

The mechanical module M2 comprises a motor MB, comprising an output shaft 130, which rotates the transmission means 8b. These include in particular a worm 132, which meshes with a toothed gear 134, forming a wheel and worm assembly. The pinion gear is connected to the drive shaft 70. The motor MA and the transmission means are housed at least partially in a first portion 60A of the housing 60. A second portion 60B of the housing 60, by its assembly with the first portion 60A by means of fastening means 63, to constitute the housing 60.

The first part 60A of the housing 60 comprises suitable housings 260, in particular for the motor MB, its output shaft 130, the worm 132, the toothed gear 134.

The worm 132 is further maintained on either side by bearings 136, 137. The bearings 136, 137 are housed in suitable housings 266, 267. These are formed by housings 266A, 267A of the first housing portion and equivalent housings (not shown) located symmetrically on the second housing portion 60B. The assembly of the two housing parts 60 form the housing 266, 267 of the bearings, in the form of baths receiving these bearings. Sidewalls 268A, 269A, 270A, 271A limit the axial displacements of the bearings. The bearings 136, 137 are slid freely in the first 60A and the second 60B housing part 60, but could also be tightly mounted.

The bearings 136, 137 are dimensioned so as, on the one hand, to absorb the radial forces related to the rotation of the worm 132 under the action of the motor MB and, on the other hand, to take up the axial forces on the screw without end 132 in case of over-torque at the gear pinion 134, related to the wind or an intrusion attempt.

Indeed, these axial forces may occur due to forces applied to at least one of the wings, in particular due to gusts of wind, particularly when the flap is in the intermediate position between the fully open position and the fully closed position of the leaves, or an intrusion attempt when the shutter is closed. These forces on the leaves are transmitted along the kinematic chain, that is to say at the arms and then the drive shaft 70 and the pinion 134 to the worm 132.

The dimensions of the bearings affect the range of the bearing but also the distribution of the contact pressure on the side walls 268A, 269A, 270A, 271A of the housing 266, 267 of the bearings 136, 137.

The bearings 136, 137 are chosen with a larger outer diameter than if they were sized only for the recovery of radial forces. Indeed, the greater the area of force recovery with the housing (the surface of the side walls 268A, 269A, 270A, 271A of the housing 266, 267 of the bearings 136, 137) is important, the lower the pressures thereon will be . The risk of transmission of these axial forces to the motor MB is decreased.

A solution with a single bearing, placed on one side of the worm 132 is also conceivable, the radial forces between the wheel and the screw, which would then be unbalanced, could be offset by other means, such as a bearing or a direct support of one side of the worm 132 by the housing 60.

The Figures 13 to 16 show the ends 10a, 10b of the protective cover 10 provided with complementary parts. A first complementary part 15, called cable protection, comprises a groove 17 in which is housed a cutout of the protective cover 10, the cable protection member being held by friction or clipping on the edge of the protective cover. The first protection part comprises a cable duct 19. When the protective cover is mounted on the electromechanical module M1 or mechanical M2, the first protective part is slidable and positioned on the cable, where it This prevents the cable from being damaged by the sharp edge of the finishing cap 10. The second end 10b of the protective cap 10 is provided with a second complementary piece 16. This is intended to complete the finishing cap and hide the cut at its end 10b. In the same way as the play of cable protection, it comprises a groove 18 in which is housed the cutout of the protective cover 10.

The invention is described above relating to the installation of a motorization assembly on a lintel, a lintel being generally defined as an architectural element for supporting the materials of a wall above an opening in a building. . It is likewise applicable to the installation of a motor assembly in the lower position of the opening, that is to say at a threshold of the opening. The terms linteau and threshold both correspond to an architectural element of an opening. They are generally interchangeable in the description.

In the particular case where the motor assembly is fixed on a threshold or support below the opening, an additional protective cover 12, shown in FIG. figure 10 , may be added and fixed in particular on the electromechanical module M1, to protect the electronic control unit 20 water flows from the lintel, splashing water (from rain, cleaning or other) , or condensation effects, under the finishing cap 10. The motor assembly 1 provided with the two covers thus has a protection type double layer or double skin, that is to say that if condensation is formed, it will form under the finishing cap 10 (which acts as an outer layer), but not under the protective cap 12 (which acts as an inner layer). The drops of condensation formed under the finishing cap 10 falling on the protective cover will be slid on the surface of the latter vis-à-vis the finishing cap.

The protective cover can simply be placed on the electromechanical module M1 by being stopped vertically on the housing 60 of the module or on the frame member 40a. The protective cover can also slide freely along the module and be stopped axially by its first edge 12a.

The protective cover 12, like the finishing cap 10, has a tunnel shape. It is preferably formed by thermoforming, a technique that allows for low thicknesses while ensuring the straightness of the workpiece (small deformation of the workpiece) along its length. The outer surface of the protective cover may include areas of extra thickness 13 forming points of contact between the protective cover and the finishing cap 10 when it is installed on the protective cover. The longitudinal ends 12a, 12b or edges of the protective cover are bevelled to ensure a good flow of water on both sides of the protective cover.
