Definitions
- the invention relates to a parabolic antenna for receiving or emitting electromagnetic waves, in particular for receiving radio and television programs, consisting of a bowl-shaped mirror (parabolic mirror) with an outer edge and a detector or radiator in the focal point of the parabolic mirror.
- a parabolic antenna for receiving or emitting electromagnetic waves, in particular for receiving radio and television programs, consisting of a bowl-shaped mirror (parabolic mirror) with an outer edge and a detector or radiator in the focal point of the parabolic mirror.
- Parabolic antennas for receiving radio and television programs are becoming more and more common. They are used for the reception and / or for the emission of electromagnetic waves 15 and consist of a parabolic mirror, the outer edge of which is flanged, and a detector or radiator at the focal point of the parabolic mirror. Depending on their orientation towards a specific satellite, parabolic antennas enable the reception of various radio and television programs, including those in foreign languages. The user is free to choose the program and not tied to the offer, which is fed into the underground cable network. In contrast to the cable networks operated by the telecommunications companies, there are no further 25 usage costs for satellite reception.
- parabolic antennas have led to the fact that, especially in larger residential complexes, each individual residential unit has its own parabolic antenna, which can be mounted on building icons 30 or directly on the house walls.
- the optical The effect of such house facades is severely impaired due to the parabolic antennas, which usually have a uniform gray or white basic color.
- the invention has for its object to improve the appearance of the parabolic antennas and at the same time to increase their reception performance.
- the object is achieved by a parabolic antenna, which is characterized in that the parabolic mirror is extended on its outer edge over the entire circumference or part of the circumference by a one-piece attachment or an attachment consisting of several individual attachment elements.
- the main idea is that the components of the parabolic antenna remain essentially unchanged and at the same time embellish the visual appearance and improve the reception performance of the parabolic antenna.
- Receiving power can be brought about by enlarging the mirror surface by means of the attachment and the attachment elements.
- the one-piece or multi-piece attachment can be attached to the outer edge of the parabolic mirror during or after assembly of the parabolic antenna.
- the attachment or the attachment elements increases the surface of the parabolic mirror reflecting into the focal point by the attachment or the attachment elements continuing the curvature of the parabolic mirror.
- the entire essay or individual is also within the scope of the invention that the entire essay or individual
- Attachment elements do not continue the curvature of the parabolic mirror. In these embodiments, the advantage of design improvement is in the foreground.
- the attachment elements can have a uniform or different shape and / or color
- the attachment elements are distributed equidistantly over the outer circumference of the parabolic mirror.
- the attachment elements are distributed over the outer circumference of the parabolic mirror to represent figures with an uneven spacing.
- Utilization of design features provides that the attachment elements, individually or as an ensemble, interact with the parabolic antenna to create an object, e.g. symbolize a sun, a star, a flower or a living being. In the case of a sun or one
- Sterns would e.g. several attachment elements of uniform size with equidistant distribution on the outer circumference of the parabolic mirror symbolize the rays of the sun or the star:
- attachment elements of different sizes, shapes and colors could be used to define the flowers and
- the attachment or the attachment elements are connected with a ring which is on the outer edge of the Parabolic mirror is attached.
- the ring can have a rail-like profile in which the attachment elements are guided and can be locked in the respective position.
- the attachment of the attachment, the attachment elements or the ring carrying the attachment or the attachment elements to the parabolic mirror can be carried out in various ways.
- the attachment by welding and / or screwing and / or gluing is preferred.
- a clamping mechanism can also be used to attach individual attachment elements.
- the flanged edge of the parabolic mirror is encompassed by the clamping surfaces and clamping edges of the clamping mechanism connected to the attachment element.
- the attachment or the attachment elements consist entirely or partially of a material that reflects electromagnetic waves. If the attachment or the attachment elements are oriented accordingly, more electromagnetic waves are reflected in the focal point of the parabolic antenna. It is provided that the attachment or the attachment elements consist entirely or partially of a flexible material.
- the flexible attachment components can advantageously be brought into a position that corresponds to the curvature of the parabolic mirror and thus increases its effective area.
- the attachment or the attachment elements consist entirely or partially of a UV-resistant and / or weather-resistant material.
- a UV-resistant and / or weather-resistant material such as metal and / or plastic.
- wood is also conceivable if a design improvement alone is to be achieved.
- the attachment elements made of flexible material are passed through by a rope to adjust their angle of inclination.
- the angle of inclination of the attachment elements is changed and held in the desired position by the rope that can be fixed at the opposite end.
- FIG. 1 shows a section through the central plane of a parabolic antenna consisting of a dish-shaped parabolic mirror 5 and a detector 6, which is attached to a house wall. On the outer edge 4 of the parabolic mirror 5, an attachment 1 is attached, which projects essentially radially outward.
- the parabolic antenna shown in cross section in Figure 1 can be seen from the top.
- the essay 1 encloses the here circular parabolic mirror 5 and is attached to its outer edge 4.
- the essay is intended to symbolize the petals of a flower, the inflorescence being formed by the parabolic mirror 5.
- the detector 6 is positioned in the middle of the parabolic mirror 5 via a fastening arm.
- FIG. 3 shows an attachment constructed from attachment elements 2.
- the attachment elements 2 are attached to a ring 3 which is connected to the outer edge 4 of the parabolic mirror 5.
- the detector 6 belonging to the parabolic antenna can be seen in the center of the parabolic mirror 5.
- the attachment elements 2 are intended to represent a mouse.
- the representation of other living beings or figurative representations, such as cartoon characters, is also conceivable.
