Description

SPECIFICATION A DISH ANTENNA MECHANISM TECHNICAL FIELD

The present invention relates to dish antenna mechanisms comprising a dish-shaped reflector, an assembly body connected to the reflector and a rigid item in order to fix said reflector at a position, and relates to the assembly of these.

PRIOR ART

Satellite broadcasting can be monitored via a dish antenna, a satellite receiver (set-top device) and a screen. Antennas collect the radio waves broadcasted in space; antennas are devices which provide broadcasting of the radio waves in transmission lines (receiver antenna) or which broadcast the signals coming from transmission lines to space as waves (transmitter antenna). Antennas are dimensioned and shaped in accordance with wavelengths and in general, they are named according to wavelengths. All systems which have long-distance or short-distance access like radio and TV broadcasts, GSM, wireless, wireless announcement systems, radars, bluetooth devices have one each antenna system.

Since receiver antennas have a dish-like reflector surface, they are named as dish antenna. The reflector surface collects high-frequency and weak radio waves, coming from the satellite, at a point, and a LNB receiver which receives these waves changes the frequency bands and strengthens the waves and transmits the waves to a set-top device and presents them to the user.

Dish antennas are located at the roofs and balconies of buildings in order to able to receive the radio waves transmitted by the satellite. Fixation of the dish antenna reflector to a rigid item at the correct position is realized by assembly bodies. Assembly bodies are pieces connected to the dish antenna reflector and which can be held onto a rigid surface like wall, pipe. In the present art, assembly bodies are held onto the dish antenna reflectors by means of a connection element. Said connection element may be a bolt or screw. The coating, existing on the openings provided on the assembly body for fixing of the bolt, is worn in time as a result of the effect of screws, and the exposed metal is rusted through the locations worn, and the rusting layer is spread on the reflector. The dish antenna reflectors lose their function when they are rusted. Moreover, when rusting occurs and when the screws placed to the openings are tightened together with the nut, the reflector is partially deteriorated in shape and thus, the aerodynamics of the reflector is deteriorated. As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a dish antenna mechanism, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

The main object of the present invention is to provide a dish antenna mechanism which can be easily assembled.

Another object of the present invention is to provide a dish antenna mechanism which is not substantially prone to rusting.

In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is a dish antenna mechanism comprising a dish-shaped reflector, and an assembly body connected to the reflector and a rigid item in order to fix said reflector at a position. Accordingly, the subject matter dish antenna mechanism is characterized by comprising a hanger element connected to the reflector and said hanger element comprises housing, said assembly body comprises a hanger arm which can be placed into said housing. Thus, the reflector and the assembly body are connected to each other without punching a hole on the reflector, and a compact antenna mechanism is obtained which can be easily dismantled and assembled.

In a preferred embodiment of the invention, the hanger element comprises at least one housing hole opened to the housing, the hanger arm comprises at least one hanger assembly hole provided so as to be positioned mutually with said housing assembly hole when the hanger arm is placed into the housing, at least one connection element is provided which passes through said housing assembly hole and said hanger assembly hole and which provides connection of the hanger element and the hanger arm to each other. Thus, after the assembly of the dish antenna and the assembly body, the unintentional movement of the reflector is at least partially prevented. In another preferred embodiment of the invention, said connection element is a bolt.

In another preferred embodiment of the invention, said hanger element comprises at least one first foot extending outwardly from the convex surface of the reflector, at least one second foot and a body connected to a point provided on the first foot and connected to a point provided on the second foot.

DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject matter dish antenna connection mechanism (1 ) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In an exemplary embodiment as in Figure 1 , the reflector (100) has a parabolic form in a manner focusing the radio waves, arriving thereon, at a region. In other words, the reflector (100) is in the form of a dish comprising a concave surface where the radio waves are reflected and a convex surface remaining at the rear side of this surface. The assembly body (200) is connected to the reflector (100). The assembly body (200) is held onto a rigid item (500) and provides the reflector (100) to stay at a fixed position in order to receive the radio waves. Said rigid item (500) can be a beam or a wall. Said assembly body (200) moreover may carry a receiver arm (400). Said receiver arm (400) holds a receiver (300), which receives the radio waves focused by the reflector (100), at a fixed position towards the concave surface.

In more details, with reference to Figure 2a and 3a, the reflector (100) comprises at least one hanger element (1 10). Said hanger element (110) comprises a first foot (1 13) extending outwardly from the surface of the reflector (100). Said hanger element (1 10) moreover comprises a second foot (1 14) extending outwardly from the convex surface of the reflector (100) preferably in a parallel manner to said first foot (1 13) and having a pre-calculated distance with respect to the first foot (1 13). Moreover, the hanger element (1 10) comprises a body (1 12) whose one end is connected to the first foot (1 13) and whose other end is connected to the second foot (1 14). In this exemplary embodiment, the body (1 12) is connected to the ends of the first foot (1 13) and the second foot (1 14), which are far from the reflector (100). In this exemplary embodiment, the first foot (1 13) and the second foot (1 14) may also comprise a base part (1 15) which joins the walls thereof which are on the same side with each other.

The reflector (100) is defined as a housing (1 1 1 ) encircled by the first foot (1 13), the second foot (1 14) and the body (1 12). The hanger element (1 10) comprises at least one housing assembly hole (1 16). In this exemplary embodiment, the housing assembly hole (1 16) is opened to the housing (1 1 1 ) through the body.

There is an assembly hole (202) also on the assembly surface (201 ). The assembly hole (202) is positioned such that the hanger assembly hole (21 1 ) and the housing assembly hole (1 16) correspond to each other. Thus, they may be connected to each other by passing a bolt through them.

The operation of the present invention whose details have been described above is as follows.

The hanger arm (210) is placed to the housing (1 1 1 ). The hanger arm (210) and the hanger element (1 10) are connected to each other by means of a connection element (600) (in this exemplary embodiment, by means of a screw and a nut connected to the screw) passed through the housing assembly hole (1 16) and the hanger assembly hole (21 1 ). Thus, assembly is provided without an opening which affects the concave surface in the reflector (100). Moreover, the coating, provided on the concave surface of the reflector (100), and the coatings, provided on the peripheral surfaces which may affect this coating, are not tightened by means of connection items like bolt, screw which may damage to the coating. As a result of this, the rusting occurring after the coating abrasions formed by the screws passing through the holes existing on the concave surface and the aerodynamic structure deterioration formed as a result of tightening of the screws to these holes are eliminated, and the usage lifetime of the reflectors (100) is increased. With reference to Figure 4a, in another exemplary embodiment of the present invention, the body (1 12) of the hanger element (1 10) is connected from its ends to the surfaces of the first foot (1 13) and the second foot (1 14), facing each other, so as to be at a distance which is equal to a predetermined height. The part which remains between the first foot (1 13), the second foot (1 14) and the body (1 12) is defined as housing (1 1 1 ). The extensions of the first foot (1 13) and of the second foot (1 14), which remain on the surface of the body (1 12) provided on the opposite side of the housing (1 1 1 ), are defined as the first wall (1 17) and as the second wall (1 18).

With reference to Figure 4a, in this exemplary embodiment, the hanger assembly hole (21 1 ) is provided in the part where the body (1 12) of the hanger arm (210) is connected to the assembly surface (201 ). The hanging item (212) is provided in a compliant form to the housing (1 1 1 ). In this embodiment, the hanging item (212) is in the form of a hook.

In this embodiment, the receiver arm (400) is inserted into the housing (1 1 1 ), and the connection item (600) is passed through the hanger assembly hole (21 1 ), the housing assembly hole (1 16) and the assembly hole (202). The first wall (1 17) and the second wall (1 18) partially encircle the hanger arm (210) from the lateral sides and they prevent rotation of the hanger arm (210) around the axis of the connection item (600).

The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description.
