Description

(2). The present invention relates to the technical field of devices

  used for the motorization of a window or a sliding opening in order to allow opening or closing of the latter without direct action of a user on the window after a possible unlocking or locking. In the above field, a Japanese patent application JP-11-204778 proposed a motorization device comprising a rack adapted on the sliding window frame. This device also comprises an electric reduction motor fixed astride a corner of the wall defining the window. The reduction motor is mounted on a tilting support, so that it can be moved between a engaged position in which a drive pinion, driven in rotation by the reduction motor, meshes with the rack to move the sliding frame in translation and a disengaged position in which the operating pinion no longer meshes with the rack and the slide must be opened by hand. Such a device effectively makes it possible to ensure the opening of a sliding opening by means of an electric motor, but has the disadvantage, on the one hand, of being particularly unsightly and, on the other hand, of not being able to 8tre adapted on all types of windows and especially on sliding doors or windows. Furthermore, given its method of attachment, such a motorization device is subject to very significant constraints when maneuvering large and heavy sliding frames due to the glazing surface put in

artwork.

  It therefore appears necessary to have a new type of device for the motorization of a window which is both simple to implement aesthetically and suitable for all possible configurations of

sliding windows or windows.

  In order to achieve this objective, the invention relates to a device for the motorization of a sliding window or bay comprising a frame and at least one frame sliding in the frame, device of the type comprising: - a rack intended to be adapted on the sliding frame, - an electric motor driving a pinion of man_uvre intended to mesh the rack of the sliding to move

  in translation the chassis in the frame.

  According to the invention, the device is characterized in that it comprises: a false upright which, on the one hand, comprises a chamber in which the electric motor is fixed and has, in the vicinity of one of its ends, a window located opposite the man_uvre pinion and, on the other hand, is intended to be adapted to the front of the frame, so as to mesh the man_uvre pinion with the rack,

  - And means for fixing the two ends of the false-

  upright on the frame and / or an adjacent support.

  The use of a false upright, preferably located in front of the assembly constituted by the frame and the sliding frame, has the advantage of constituting a system which integrates visually perfectly with the assembly constituted by the sleeping and its sliding. In addition, the fixing of the false upright, at its two ends and preferably high and low, makes it possible to obtain a system which is effectively resistant to the significant stresses appearing when the engine is started

  electric and at the start of translation of the sliding chassis.

  According to the invention, the means for fixing the two ends of the false upright, on its support and most often on the wall elements forming the surround of the window, can be produced in any case

appropriate.

  According to a preferred, but not strictly necessary, form of embodiment of the invention, the two ends of the false upright are hollow and the fixing means comprise at least: - a base comprising a body intended to fit into the false - rising at one of its ends and a fixing head, - a fixing interface comprising fixing means

  on a support and fixing means on the fixing head.

  Preferably, the false upright is produced in the form of a tube which is supplied in a length corresponding to the maximum height of a window capable of being fitted by means of a motorization device according to the invention. . The electric motor is then fitted inside the tube in the vicinity of one end of the latter, so that a large part of the false upright, situated between the motor and its other end, is empty. Thus, an operator, responsible for setting up the motorization device according to the invention, can adapt the length of the false upright by simply cutting the constituent tube of the latter. According to an embodiment characteristic of the invention, the base has, at its head, a rabbet for receiving the fixing interface and bores for the installation of screws for securing the fixing interface to the fixing head. The attachment interface can then

  be performed in any suitable manner.

  According to one embodiment, the fixing interface is constituted by a spacer of substantially parallelopiped shape

  having fixing means on a support and on the fixing head.

  According to another embodiment of the fixing means, the base has on the one hand, at the level of its head, a groove for receiving a fixing wing offered by the fixing interface and, on the other hand, at least one bore opening in the groove for a screw

  of immobilization of the wing of the interface.

  The fixing interface then has a fixing foot on a support from which the fixing wing extends. So the interface of

  attachment may have a T-shape or a square shape.

  According to a characteristic, preferred but not strictly necessary of the invention, the rotor of the electric motor can turn freely when it is not supplied. Thus, the sliding frame can be moved freely following, for example, a stop on an obstacle in an intermediate position between a complete opening and a closing.

complete with sliding frame.

  According to another characteristic, the device according to the invention,

  includes means for controlling the electric motor.

  Such control means can be made in any appropriate way and preferably include means making it possible to ensure remote control, by radio or infrared waves, of the

  operation of the electric motor.

  According to an alternative embodiment, the control means comprise obstacle detection systems in order to interrupt the operation of the engine in the event of a resistance to advancement greater than normal of the slide operated. Such detection means can then avoid the risk of injury by jamming between the sliding and the window frame equipped with a

  motorization device according to the invention.

  According to another alternative embodiment, the control means comprise means for blocking the rotation of the motor in the sliding closing position. Thus, the motorization device according to the invention constitutes a system for locking the movement of the slide in order, for example, to oppose

  inadvertent or ill-intentioned openings.

  Preferably, the means for blocking the rotation of the motor are only activated when the slide is in the position of

complete closure.

  The invention also relates to a sliding building window of the type comprising a frame fixed in the opening of a building wall and, at least, a sliding frame in the frame. The window also comprises a motorization device according to the invention, the rack of which is integral with the sliding frame and the false upright of which is immobilized by the fixing means on wall elements adjacent to the frame and / or on the frame, so to be placed vertically in front of the window, the operating pinion meshing with the rack of the

sliding frame.

  According to a preferred but not strictly necessary embodiment, the sliding window comprises two sliding frames, one of which is operated by the motorization device and the second frame comprises stop means, in the first frame, so that a translation, in the direction of opening the first sliding frame, causes movement in the direction of closing the

second chassis.

  Various other features of the invention emerge from the

  description below made with reference to the accompanying drawings which

  illustrate non-limiting embodiments of devices for the

  motorization of a sliding window according to the invention.

  Figure 1 is a perspective showing a window with two

  sliding frame fitted with a motorization device according to the invention.

  Figure 2 is a section along the plane 11-ll of Figure 1.

  Figure 3 is a schematic section along the lil-lil plane of the

figure 2.

  FIG. 4 is a partial section, substantially similar to FIG. 2, showing another embodiment, of a motorization device according to the invention and more particularly of the means of

fixing the latter.

  A motorization device, in accordance with the invention, as illustrated in FIGS. 1 to 3, and generally designated by the reference 1, is intended to equip a window 2 comprising a window frame 3 in which is fitted at least one frame sliding 4 and, according to the example

  illustrated, two sliding frames 4 and 5.

  The motorization device 1, according to the invention, is then designed and adapted to ensure mechanical translation without direct action by a user of the sliding frame 4 which will be considered to be oriented towards

Inside the building.

  Thus, the motorization device 1 comprises a suitable rack, in the lower part of the sliding frame 4, over at least part of its length, so as to extend sufficiently to correspond to a complete movement of opening and closing of the

sliding 4.

  According to an essential characteristic of the invention, the motorization device 1 further comprises a false upright 11 which comprises a chamber 12 in which is fixed or disposed an electric motor 13. In order to be able to move the chassis 4, the electric motor drives an operating pinion 14 intended to mesh the rack 10. Preferably but not strictly necessary, the motor 13 and pinion drive system 14 assembly is constituted by a tubular electric geared motor. The false upright 11 furthermore comprises, near its lower end 15, a window 16 situated opposite the operating pinion 14. The window 16 is then arranged so as to allow the passage of the rack 10 inside the false upright 11 to authorize a gear of the operating pinion 14 with the rack 10, as the

  more particularly shows figure 3.

  The motorization device 1, according to the invention, further comprises means for fixing 20 and 21 of the low and high ends 22 of the false upright 11 on an adjacent or constituent support of the motorized window 1. According to the illustrated example, the fixing means and 21 are formed by two kinds of chairs allowing a fixing

  direct of the false upright on the frame 3 of the sliding door.

  The motorization device 1, in accordance with the invention, further comprises, in a manner referred to as is not strictly necessary,

  remote control means 25 for the electric motor 13.

  Thus, the control means 25 are constituted by a block connected, on the one hand, to the electrical network by a line 26 and, on the other hand, to the electric motor by a line 27. The control means 25 also comprise a radio or infrared reception system to receive the electric motor operating control orders transmitted by a radio or infrared remote control depending on the

transmission mode selected.

  Thus, according to the information received, the electric motor rotates either in the direction of the arrow F1 in FIG. 3 to cause a translation of the chassis 4 in the direction of the arrow F2. So, as a reference, the control unit 25 then comprises means for detecting resistance to opening, as a function of the behavior of the electric motor 13. Thus, these resistance detection means avoid any injury to a person in the vicinity near the window when operating the sliding door. The operation of the electric motor can, moreover, be interrupted at any time depending on the degree of opening desired by the user. In addition, the control means 25 preferably comprise end of stroke detection means in order to prevent any rotation of the motor in the direction of the arrow F1 when the slide 4 is

fully open.

  Similarly, the control means 25 are adapted to power the motor 13 so as to obtain a rotation of the pinion 14 in the direction of the arrow F3 and therefore a translation of the slide 4 in the direction of the arrow F4 corresponding to a window closing movement. As for the opening, the control means 25 preferably comprise an end of travel system to prevent rotation of the motor in the direction of the arrow F3 when the slide 4

is completely closed.

  Preferably but not necessarily, the device according to the invention also comprises a system for blocking or locking the rotation of the motor when the slide 4 is completely closed in order to prevent any untimely or ill-intentioned maneuvers of the slide 4. The implementation of such a locking system integrated into the false upright thus avoids the use of annexed locking system integrated into the sliding and the frame. However, it should be noted that if the frame and the slide include a device for locking or blocking the frame in the closed position, it will be necessary to unlock the latter before controlling the motor to open the slide. Similarly, it will be necessary to relock the device

after closing the sliding door.

  P referenced ma is not strictlyeme nt necessary, the electric motor 13 is also chosen so as to be able to rotate freely when it is not powered. This advantageous arrangement of the invention makes it possible, when stopping on an obstacle, to avoid applying too great a pressure on the obstacle when the power supply to the engine is cut off.

the control means 25.

  It therefore appears that the motorization device according to the invention makes it possible, relatively simply and particularly effective, to motorize a sliding window. In addition, the vertical arrangement of the false upright 11 allows it to integrate perfectly into the structure of the window 2. The false stud 11 is then preferably fixed, so as to be disposed in the overlap area of the frames 4 and 5, in the closed position of the window 2. Thus, in this closed position, the false upright 11 gives the visual impression of being

  integrated into the window frame it equips.

  According to a preTerated variant of the invention, the slide 5 comprises a stop 30 arranged so that during an opening movement of the slide 4, the slide 5 is brought into closure by the slide 4. This advantageous arrangement of the the invention then makes it possible to ensure that the window is perfectly closed by first ordering a complete opening of the slide 4 then a closing of

this last.

  As has been specified above, the false upright 11 of the motorization device according to the invention can either be fixed to a window frame provided for this purpose, or, on the contrary, be attached and adapted so as to be disposed at the face level, facing

  inside the building, from a pre-existing window.

  To this end, the invention proposes to implement specific fixing means designed to meet all the configurations likely to be encountered by an installer of the motorization device according to the invention. As illustrated in FIG. 4, the false upright 11 is then preferably but not necessarily

  constituted by a tube of cylindrical shape of revolution.

  The fastening means 20 and 21 then comprise, for each end 15 and 22 of the false upright 11, a base 35 which

  comprises a body 36 intended to be fitted into the false upright 11.

  The base 35 further comprises a fixing head 37 intended to

  cooperate with a fixing interface 38.

  According to the example illustrated, the base 35, located at the upper end 22 of the false upright 11, has at its head 37 a rebate 40 for receiving the fixing interface 38. According to the example illustrated, the interface 38 is then constituted by a spacer of substantially parallelepiped shape having a width and a height corresponding to the width and to the height of the rebate 40. The spacer 41 preferably has means to allow its fixing on a wall element 42 adjacent to the frame 3. The means of fixing the spacer 41 are for example constituted by through bores allowing the installation of fixing screws. Thus, it is possible to adapt the length of the spacer 41 according to the mounting configuration and to have, after this cutting, bores always allowing

  the installation of the fixing screws.

  The spacer 41 moreover preferably comprises means 43 to allow it to be secured to the fixing head. These fixing means 43 may for example be constituted by

  fixing screw receiving bores.

  Furthermore, according to the example illustrated, the fixing base 35 has passages 45 for the supply line 26 of the motor 13 and

of its control means 25.

  Of course, according to the invention, the fixing base 35 could be made of another shape insofar as it always has, on the one hand, a body 36 intended to fit into the false- amount 11 and,

  on the other hand, a fixing head 37.

  Thus, according to the example illustrated, the base 35, implemented to ensure the fixing of the lower end 15 of the false upright 11, has a fixing head 37 which has a conformation different from that of the fixing head 37 of the base 35 used to fix the end

high 22 of the false upright 11.

  According to this example, the fixing head 37 of the lower base has, as fixing means, a transverse groove 46 intended to receive a wing 47 of the fixing interface 38. According to the illustrated example, the interface fixing 38 is made in the form of a T-piece which then has a fixing foot 48 from which extends the wing 47. The fixing head 37 also has a bore 49 opening into the groove 46 for either a support screw

  coming to immobilize the wing in the groove, or a pin.

  Of course, the fixing interface 38 could be produced other than in the form of a T-piece and for example made up

by a square piece.

  It should be noted that the mounting base 35, used for the lower end 15 of the false upright 11, is particularly suitable

  for fixing at the end of the false upright either on the floor or on the ceiling.

  According to the example illustrated in FIG. 4, the wing 47 of the T-fixing interface 38 is parallel to the plane of the window. However, the wing 47 will preferably be arranged perpendicular to the plane of the window so as to allow mounting of the false upright 11 by a simple translational movement.

in the direction of arrow F6.

  Furthermore, the fixing base, used for the upper end 22 of the false upright 11, is more particularly suitable for fixing

in console.

  Thus, the two base conformations 35 described and illustrated in FIG. 4 make it possible to take into account most of the configurations likely to be encountered, when the motorization device according to the invention is put in place, on windows or

  pre-existing bays in the context of renovation operations for example.

  In the example illustrated in FIG. 4, the fixing bases 35 are fitted to a false upright 11 constituted by a tube. However, the bases 35 could also be used on a false amount of which

  only the ends 15 and 22 would be hollow.

  Furthermore, according to the examples described above, the

  motorization device 1 is used on a sliding window.

  S Of course, the motorization device 1 according to the invention could also be adapted to a window comprising only a single sliding element such as a so-called pocket window whose sliding element comes into position

  opening place in a hollow partition.
