    Technical field of the invention
    The invention relates to an electrical supply device for a movable leaf of an automatic door driven by a control mechanism integral with the chassis, said leaf being supported by at least one carriage, which rolls along a rail main bearing when moving between the open and closed positions.
    It relates in particular to the supply of a device for partially lighting the faces of the leaves by providing light through the edge of the glass leaves.
    The light is generated by strips of leds on each side on the edge of the leaf allowing the interior lighting of a glazing in order to diffuse a poster or a message thanks to a specific white tinted adhesive glued directly on the glazing, or by a stud and backlight system using the back light technique. Means are used to power the LED strips to illuminate the glazing during the movement of the movable leaves of the automatic door.
    State of the art
    Devices for lighting a glazing with strips of LEDs arranged on the edge of the glazing are known from document WO2010029658 from Nichia. Variants still describe the supply of light by backlighting (such as document KR2004085771 by ST GOBAIN or with colored lights according to document WO2010124951 by ST GOBAIN. Numerous applications have resulted therefrom, for example in the automobile for sunroof lighting according to documents FR2986854 & FR 2978524 (St Gobain), or of refrigerator doors (Patent FR 2978525 of St Gobain).
    Two technologies for lighting a glazing by strips of LEDs arranged on the edge of the glazing, are developed:
    - The lighting of a white diffusing film printed with the message to be displayed, laminated directly on the rear side of single-sided glazing. This is the simplest technique, the limits of which are the area to be lit, and the area of the glazing.
    - Lighting by diffusion of light in the interior space of a double glazing, whose edge of access to the light is polished, and requiring a layer of air between the two: one prints by jet of white ink of the diffusing points on the rear glazing, precisely arranged as a function of the distance between the light source and the diffusing points (or studs), forming a display area. Then we paste a photo or we print a message on the front glazing and on the same display area as that of the rear studs and thus, the light source, by backlight, comes to illuminate the photo or the printed message. This second technology, which is certainly more expensive, improves the quality of lighting, and the lighting surface, as well as four-color lighting.
    The patented solutions concerning these two technologies solve the various problems posed, such as the management by electronic card of the operation of the LEDs, the light, the coloring, the diffusion of this in the direction of a diffusing film tinted in the mass and adhesive. directly on the back of the glazing, the various designs of the support and settings of the LED strips to optimize the dispersion of the calories generated, the sealing or the simplification of the mounting of the LED strips.
    However, all known applications relate to the lighting of a fixed glazing, or having a movement of small amplitude and slow movement like the sun roof of a vehicle, or the door of a refrigerator. In addition, the requirement for operating cycles does not exceed a few thousand opening / closing times. These applications also cannot relate to large-width glazing, since the loss of brightness must be compensated by an increase in the power of the LEDs, generally incompatible with these applications, for reasons of cost, size, electrical consumption. excessive (sunroof), cooling impossible to implement or incompatible with the environment (refrigerator).
    Object of the invention
    The object of the present invention is to provide colored lighting for images printed on a diffusing film carried over the window glass. A backlighting by studs diffusing the light guided in the glass illuminates a poster or a photo carried on the glazing of an automatic door during its movement. The door then serves as a communication and signage medium for a store, a sign, a business or any other legal or commercial entity.
    Another feature of this invention is to offer different supports: image lighting, text logos on the leaf. The use of color or flashing to attract attention (green pharmacy logo), this by automatic variations in the intensity of the LEDs depending on the ambient or outdoor lighting or the flow of people detected by the radar door, etc ...
    The glazing used for these applications will be extra clear toughened or laminated glass (type 44/2) and the adhesive film on the rear side of the glazing will be of the clear, ultra-transparent type V, with white pixelated printing ink or not.
    The present invention poses multiple problems that have not been solved to date, which explains why this application is still unknown on the market:
    - The first difficulty is feeding the LEDs.
    If the mounting of strips of 18 or 20 white LEDs on the lateral edge of the glazing is known, it must be supplied with a source of energy and control during its movement, which is much faster than a sunroof and on a race up to 2 meters wide or more. The lifespan in opening and closing cycles must be of the order of a million operations. The rapid movement of the leaves of an automatic door, the acceleration / braking and the very high opening / closing frequency pose a major difficulty for the reliable supply of the motor for driving the movable leaf, by means of a electrical cable to be connected to the door frame. The solution tested according to the invention therefore consists in choosing a power supply cable with two or three conductors, which is coiled and sheathed with a polyurethane coating or equivalent suitable for a large amplitude spring effect.
    These sheathed / spiral cables were developed for industrial applications, but are offered without support or guide accessories. This type of cable, although compact, has too large an arrow to be contained and guided properly in the limited space of the carriage of an automatic door. The cable is therefore suspended from a small rail integral with the main rolling rail of the door, and in which move simple and original sliding supports developed to carry and guide the cable sliding in the rail. The carriages will be spaced to ensure the almost arrowless maintenance of the spiral cable. The principle of this mechanism offers the advantage of supporting hundreds of thousands of round trips and cycles without any failure. It is very reactive to acceleration / braking thanks to the spring effect of the sheathed cable, it is also completely silent, and very economical.
    - The second difficulty is that the space between the upper part of the leaf is limited and already occupied by the leaf rolling carriage, and the drive belt. For example, the space available in width / height for interior doors placed "in brick partition", that is to say between two thin partitions, is only 70 x 70 mm. There can be no question of leaving an electric cable, even a coiled one, to move without risk and to get stuck in the guide and drive mechanism of the door. This problem is solved by the device described above, which is very compact and the amplitude of which is controlled in the three directions longitudinal, lateral and vertical in the available space.
    - The third difficulty is that the surface of the leaves and its on-board signage can be very large, several M 2 , which requires, in the state of the art, powerful and numerous LEDs, in order to guarantee a homogeneity of the lighting. The consequence is that the installed power can become prohibitive in terms of electrical consumption and the generation of heat incompatible with the environment of an automatic door. This problem will be partially solved thanks to pixelated “full white” light supports, the light catching only the pixels, making it possible to optimize the installed power and the homogeneity of the lighting. These pixels will advantageously consist of small diffusing patterns, and then larger patterns. For large area logos, we will use a pixelated white or gradient-controlled transparent ink on transparent adhesive film. All of these provisions allow this problem to be fully addressed.
    In general, the device for supplying power to the movable leaf supported by at least one carriage which rolls along a main rolling rail, is characterized by:
    a spiral electric cable electrically connected between a low voltage power source by transformer fixed to the chassis, and a tension controller secured to the movable leaf, said cable being wrapped in an insulating sheath, a guide rail for sliding supports introduced between the isolated turns of the cable at regular intervals to maintain the cable without bending during its deployment, said guide rail being fixed to the main running rail.
    Each sliding support comprises an H-shaped metal wire frame, having one of the branches capped with an anti-friction sheath configured to slide between the isolated turns of the cable, and the other branch provided with a plastic guide. can slide without wear in the guide rail.
    The receiver to be powered electrically on the movable leaf of the automatic door, can be a lighting system, a sensor or an actuator with or without electronic circuit.
    According to a preferred embodiment, the supply device is connected to a device for lighting the glazing of the leaf by at least one LED strip fixed along the lateral upright to obtain lighting by the vertical edges of the glazing during movement. . The distance separating the LED strip from the side edges of the glazing is between 1mm and 1.5mm, and preferably of the order of 1.2mm to obtain optimum light diffusion.
    According to a characteristic of the invention, the glazing is of the extra clear or toughened laminated type, making it possible to illuminate by the edges a printed diffusing film adhesive to the glazing of the sliding leaf.
    According to an alternative embodiment, the lighting device is associated with double glazing of the extra clear or tempered type, the strip of LEDs allowing the diffusion of light into the internal space of the double glazing containing a layer of air. Diffusing points are arranged on the rear glazing according to their distance from the light source, to form a backlit display area.
    The diffusing film adhesive to the glazing can be pixelated
    Preferably, the round wire frame is made of stainless steel with a diameter between 3 and 5mm, the sheath is made of Teflon, the guide is made of polyacetal, and the small guide rail is made of extruded aluminum.

    Description of a particular embodiment
    With reference to FIGS. 1, 2, 5 and 6, a mechanism for the electrical supply of the lighting of the leaves 2 by LEDs (light-emitting diodes) consists of a spiral electrical cable 7 provided with an insulating polyurethane sheath or similar material. Sliding supports 8a, 8b, 8c, 8d, are inserted between the turns spaced from the sheath, so that the spiral cable 7 always remains maintained practically without bending, and sliding in a small guide rail 9, which is fixed on the main rail 5 on which the carriages 6a, 6b roll, supporting the sliding leaves 2 of the automatic door. The guide rail 9 extends in the same direction as the main rail 5.
    During the opening movement of the leaf 2 represented by the arrow O in FIG. 1, the spiral cable 7 opens while lengthening, and does not bend thanks to the maintenance of the sliding supports 8a, b, c, d which slide in the small guide rail 9. During the closing movement of the leaf 2 represented by the arrow F in FIG. 2, the spiral cable 7 closes by bringing its turns together.
    A controller 17 for controlling the LEDs is fixed to the upper part of the movable leaf 2 of the door. A transformer 12 which supplies the LEDs with low voltage energy, is fixed to the end of the main rail 5. The power cable 7 is electrically connected between the transformer 12 which is fixed, and the controller 17, being arranged between the left 2a and right 2b uprights of the movable leaf 2 by sliding in its horizontal upper frame 1.
    With reference to FIGS. 3 and 4, LED strips 3 are fixed on the sides of the vertical uprights 2a, 2b of the leaf 2, being wedged with glazing shims 4. The heat dissipation is effected by the uprights 2a, 2b in aluminum of the leaf 2. The lighting is captured on a printed film 11 diffuser tinted white in the mass and adhesive on the glazing 10 of the leaf 2, and which can be pixelated to homogenize or increase the brightness. The distance d separating the LEDs from the side edges of the glazing 10 is advantageously between 1mm and 1.5mm, and preferably of the order of 1.2mm to obtain optimum light scattering.
    With reference to FIGS. 7 and 8, the sliding supports 8a-8d all have identical profiles, for example made up of a frame 13 of stainless steel H-shaped wire. The frame 13 is advantageously capped with a sheath 14 for example Teflon to slide without friction or wear or noise between the turns of the polyurethane sheath of the spiral electric cable 7 (see Figure 6). The other branch of the H of the frame 13 is inserted into a guide 15, for example of polyacetal of the Delrin type or any other similar plastic material favorable to sliding without premature wear on the aluminum. The guide 9 can be machined or extruded to slide without excessive play, without noise and without friction along the small guide rail 9.
    The power supply mechanism for leaf 2 previously described is simple and economical to produce, and makes it possible to supply the LED strip 3 embedded in the side uprights 2a, 2b of an automatic door in motion without risk of cable hooking. 7 power supply in the door mechanism, without additional noise to that of a motorized door, compatible with the speed of opening and closing of the doors including acceleration / braking and compatible with the very large number of operations required for this type of mechanism.
    The opening stroke of the sliding leaf 2 can reach 3 meters, and the maximum opening speed 1.5 m / second. The illuminated film can occupy an area up to 1.5 M2.
    The mechanism which is the subject of the present invention does not only concern an automatic door provided with a single leaf, but also a door often comprising two leaves. The mechanism can also equip a telescopic door comprising several leaves. In this case, each leaf of the telescopic door can be fitted with the mechanical device described in the present invention. In addition, each leaf may have signage or color, allowing a message to be rolled out as the door closes.
    It is clear that the light emitting diode lighting device can be replaced by any other lighting means, in particular halogen lamps or optical fibers.
    The power supply system according to Figures 5 and 6 can also be used to power any other receiver or sensor secured to a movable leaf of the automatic door.
    The application can also relate to a curved door, the guide rail 9 being able to be bent according to the same radius of curvature as the main rail 5, within the radius limits compatible with the angle of refraction of the light scattering in the glazing 10.
