Definitions

• the present invention relates to a sun protection or occultation device comprising main elements, namely at least one or more cradles and a geared motor, the latter being housed in a rail by means of the cradle (s), controlling the movement of at least one sun protection or concealment element and being supplied from an electric power source by an electric cable penetrating the rail.
• a sun protection device intended to be installed for example in front of a window inside a building.
• This device mainly comprises blades whose length is equal to the width of the window. These blades are movable in translation along a vertical axis and orientable around their longitudinal axis. They are linked together by cords determining the maximum spacing between two neighboring slats and the assembly, thus formed, is suspended under a mobile beam, guided by two vertical rails located on either side of the window and the movement is controlled by a gear motor.
• This beam is in fact connected by two cables to winding drums each linked to the output shaft of the gearmotor.
• the gearmotor is attached to a rail linked to the structure of the building. An electric cable for supplying the gearmotor connects it to a source of energy external to the rail. he leaves the rail from above, the U-shaped rail being open at this point.
• Patent CH 691 131 discloses a sun protection device having cradles made, for example of plastic material and having shapes suitable for positioning a gearmotor in a rail. These cradles have internal shapes allowing them to be fitted at both ends of the gearmotor and external shapes allowing them to slide without play in the rail.
• a sun protection device having cradles to adapt the shape of a gearmotor to that of a rail having a U-shaped profile.
• This device is provided with a U-shaped elastic ring, the two lateral wings of which press on the lateral wings of the rail and the intermediate wing of which presses on the gearmotor and makes it possible to maintain the latter in position in the rail.
• the rail has an opening on its underside allowing the passage of an electric power cable from the gear motor coming from outside the rail.
• the electric cable must take different directions inside the rail. The installer must therefore orient the electric cable in the rail during installation.
• the object of the invention is to provide a device which overcomes these drawbacks and improves the existing devices.
• the invention proposes to produce a sun protection or concealment device, the installation of which is facilitated and the operation secure.
• the sun protection or blackout device is characterized in that it has at least one path for the electric cable defined by at least one of the main elements.
• path is meant a means at least partially surrounding the cable to guide it over a distance greater than several times its diameter.
• Figure 1 is a cross-sectional view of a first variant of the device according to the invention.
• Figure 2 is a partial longitudinal sectional view along the plane II-II of Figure 1 of this variant of the device according to the invention.
• Figure 3 is a cross-sectional view of a second variant of the device according to the invention.
• Figure 4 is a partial longitudinal sectional view along the plane IV-IV of Figure 3 of this second variant of the device according to the invention.
• Figure 5 is a cross-sectional view of a third variant of the device according to the invention.
• Figure 6 is a partial longitudinal sectional view along the plane VI-VI of Figure 1 of this third variant of the device according to the invention.
• Figures 7 to 8 are sections of electric cable guide paths.
• the sun protection device shown in section in Figures 1 and 2 is intended to be installed opposite a window, for example outside a building.
• This device comprises blades, not shown, the length of which is substantially equal to the width of the window. They are movable in translation along a vertical axis and orientable around their longitudinal axis. They are linked together by cords determining the maximum spacing between two neighboring boards.
• the movements of the blades are controlled by a geared motor 2 driving through its output shaft 6 motion transformation mechanisms not shown.
• the gear motor 2 and the movement transformation mechanisms are housed in a rail 1 consisting of a un profile linked to the structure 20 of the building and arranged in such a way that the opening of the rail 1 is oriented upwards.
• This rail 1 can be made of sheet steel, aluminum or plastic.
• This rail 1 is linked to the structure 20 of the building by means of two supports composed of two parts.
• the first part consists of a C-shaped section 4a fixed at its intermediate wing to the structure 20 by screws.
• the second part consists of a sheet metal strip 4b which is fixed, for example by means of bolts, on the ears 12 produced on the first part. These supports thus trap the rail 1.
• cradles 3 At each end of the geared motor 2, cradles 3 have internal shapes allowing them to be mounted thereon. They also have external shapes penetrating into the rail 1 with little play. These cradles thus serve as a mechanical interface between the rail 1 and the geared motor 2, making it possible to adapt the dimensions of the geared motor to those of the rail 1.
• An elastic ring 7 having a U shape and made of an elastic material such as spring steel is positioned on the rail 1 so as to keep the gearmotor 2 in position in the rail. Its two lateral wings 8a and 8b come into contact with the wings 11a and 11b of the rail 1 and its intermediate wing comes to be housed in a shoulder 13 produced on one of the two cradles 3 in order to ensure its holding function.
• the gearmotor can be placed in position in the rail by means of a single cradle. In this case, the gearmotor has one end shaped to come into the rail and is linked at its other end to the cradle.
• An electric cable 5 allowing the supply of the geared motor 2 connects it to a source of energy external to the rail 1 and located on the structure 20 of the building. This cable 5 enters the rail 1 from the top or through an opening made in one of its wings before joining the geared motor 2.
• a curved channel-shaped path 10a produced in one of the cradles 3 makes it possible to guide and orient the cable 5 inside the rail 1.
• the channel has a circular section whose diameter is slightly greater than the diameter of the electric cable 5 .
• this channel 10a allows the cable to follow the bottom wall of the rail 1 before entering the cradle 3.
• a shape can be obtained very easily, for example by molding.
• the cable 5 can be routed inside the rail 1 in order to improve the aesthetics of the device without risking that it comes to get caught in the mechanism for controlling the movements of the blades.
• a variant of this embodiment, shown in Figures 3 and 4 differs in that the device comprises a cradle 3 having a groove 10b for orienting the cable up the rail.
• This groove has a width and a depth at least equal to the diameter of the cable 5.
• the end face of the geared motor 2 coming into contact with this cradle 3 comes to form a cover on this groove 10b for form a conduit.
• the elastic ring 7 prevents the cable 5 from coming out towards the top of the rail and guides the latter to the left.
• a variant of this embodiment, shown in FIGS. 5 and 6, differs in that the device comprises a cradle 3 having a groove 10c making it possible to orient the cable upwards outside the rail.
• This groove 10c has a width and a depth at least equal to the diameter of the cable 5.
• the end face of the geared motor 2 coming into contact with this cradle 3 comes to form a cover on this groove 10c to form a conduit.
• grooves made on the cradles and these conduits made in the cradles 3 can also be made on the geared motor or in the geared motor.
• grooves and / or several conduits are made on the cradles and on the gearmotor, so the installer can orient the electric cable in the way which seems to him the most judicious by passing it in one or the other grooves or conduits depending on the direction of installation of the device and the location of the energy source.
• grooves and conduits described above have dimensions slightly greater than those of the section of the electric cable so that it retains a play in the grooves and conduits.
• projections 30 can be made on either side of the upper part of grooves 32 so that the distance between two facing projections 30 is slightly less than the diameter of the cable so to retain it once it has been engaged in them.
• the rail may have elastic strips linked by one of their ends to the wings of the rail and making it possible to retain, by pinching between the other of their ends and the rail, the electric cable.
• the U-shaped rail is described having an opening oriented upwards, however this opening can be oriented in any other direction.
• the rail may also consist of a profile having a section shape other than a U.
