Description

The present invention relates to a "ready-to-install" wall device

  receiving antenna for programs broadcast by satellite. It generally relates to the industrial and commercial field of the manufacture and distribution of equipment intended for parabolic antennas used for the reception of signals emitted by geostationary satellites, and in particular for the reception of television broadcasts, it

  be it professional or domestic installations.

  The satellite dishes, which are more and more widespread, take their name from the characteristic shape of the reflector with which they are provided. The signals are received by at least one microwave head secured to the reflector, oriented towards the focal point of the latter and connected to the reception chain by coaxial cable. The sometimes wild installation of such antennas very often disfigures building facades and in any case degrades the aesthetics of individual villas. In addition, the antenna is always placed in addition on the facade, the roof, the chimney, in the garden, on the terrace or the balcony, without this having been originally planned. It therefore requires an additional fixing on existing elements (circled to the chimney, sealed in the wall or bolted in the ground). Figures 1 and 2 show houses with one or two satellite dishes

  mounted according to the state of the art, exposed, on the wall or hung on the fireplace.

  In all cases, drilling is necessary, for the hardware but especially for the crossing of the HF cable to the television set or the wall outlet. It is therefore very common to have to cross one or more walls, a ceiling, a floor or a slab, which can sometimes prove, in most cases, very

  difficult and laborious, even unsightly.

  The device according to the present invention aims to remedy this state of affairs. It provides excellent protection against bad weather (such as rain, snow, winds or solar ultraviolet rays) responsible for wear phenomena (acid rain, for example) and especially for adjustment (strong winds, ice, accumulation of snow), or even falls that could cause serious injury to a passerby. The device also makes it possible to visually camouflage the receiving antenna and thus improves the aesthetics of facades and roofs. (see Figures 3 and 4 which offer examples of camouflaged antennas on the same houses

than those in Figures 1 and 2).

  It consists of a "ready-to-install" assembly consisting of a parabolic receiving antenna mounted on a support mast and a frame forming an enclosure, designed to integrate into a construction wall and contain all or part of the antenna, the latter being concealed, at least for its larger

  part by a panel placed at the front of the frame.

  In the accompanying drawings, given by way of nonlimiting examples of embodiments of the subject of the present patent application: FIGS. 1 and 2, cited above, represent constructions equipped with parabolic antennas mounted in the conventional manner , Figures 3 and 4, also mentioned above, show identical constructions provided with the device ready to install according to the invention, Figures 5 and 6 show, seen from the front and from the outside, two examples of the device comprising a front panel letting the antenna head arm pass, FIG. 7 is a transverse section, perpendicular to the wall facade, of the device in FIG. 5 and FIG. 8 shows, also in transverse section, the device

  of the previous figure integrated into a wall.

  The device, Figures 3 to 8, consists of a ready-to-install monoblock 1, consisting of a three-dimensional frame 2, of the parallelepiped type

  or other, forming an enclosure containing all or part of the receiving antenna 3.

  The frame 2 can be made of various types of resistant materials such as concrete block, plastic, wood, aluminum or others. It contains the mast 4 for supporting the antenna 3 which is sealed and may include a device for

  verticality tracking and self-adjustment.

  The antenna 3 and / or the support mast 4 may be removable, in order to

  give the user the freedom to mount an antenna of his choice.

  The installation of the device is carried out during the construction of the house in one of its walls 5 or in a nearby wall, and therefore saves the high costs of subsequent installation, then carried out by a professional. It thus eliminates all the drawbacks mentioned above. It does not require any particular fitting skill, except to place it on a wall oriented in the approximate direction of the transmitter. For a geostationary satellite, for example,

  the orientation is towards the south in our latitudes.

  The device can advantageously be placed at eye level, for adjustment of the antenna much easier than balancing on a scale in

high on a wall or on a roof.

  The possibility of accessing the enclosure from inside the house or from outside can facilitate adjustments or the easy addition of accessories. The enclosure formed by the armature 2 of the device can perfectly accommodate all or part of the elements constituting a satellite reception system such as a multi-head switch decoder, antenna positioning motor, etc., by offering the

  possibility to fix them inside, on the frame.

  Cable passages can also be reserved for interior wall sockets 6 (HF socket, TV scart, mains sockets, telephone sockets) and exterior sockets 7 for one or more other antennas

  external (dish or "rake") to be connected.

  Depending on the thickness of the wall 5 on which the antenna block 1 will be mounted, according to the maximum angle of rotation authorized to the antenna 3, and according to the size of the latter, the device may or may not be completely closed and protected from the outside. Figures 5 and 6 show two examples of blocks for antennas 3 equipped with

  exterior protection panels 8, 9.

  These panels, transparent to electromagnetic waves, may include an opening 10 provided for the passage of the arm 11 carrying the microwave head 12 and for the return of the coaxial cable 13 connecting the latter to the

reception system.

  When receiving a transmission, the antenna 3 must be oriented towards the transmitting satellite. In order to increase the possibilities of choice, it is interesting to be able to modify this orientation on demand. This is the reason why recent installations increasingly include a motorized parabolic antenna whose movements can be remote-controlled directly by the user in order to receive all the satellites. It consists of a motorized mount on which is mounted the assembly consisting of the microwave head, the

  parabolic reflector and its attachment.

  In this case, the opening 10 will be arranged to allow orientation

  from antenna 2 to one or more transmitters.

  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by

similar devices.
