Abstract

PURPOSE:To simply and strongly set a parabolic antenna device by saving labor by clamping the weight of a proper weight to the tips of plural foundation legs attached to a base seat to support the pole of the antenna. CONSTITUTION:Four legs 4a, 4b, 4c and 4d are fixed with bolts 3a and nuts 3b to a base seat 3 to which a pole 2 attached with a parabolic antenna 1 is to be fixed. Weights 5, e.g., concrete road sole plates, etc., are attached with U-shaped metal fittings 6 and nuts 7 to the tips of the legs 4a-4d. They can thus be assembled easily in a short time, and the parabolic antenna can be stably set without the needs for overmuch labor and time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a parabolic antenna device in which a parabolic antenna for direct reception of satellite broadcasting can be installed.

Conventional Structures and Problems Since parabolic antennas have a large wind receiving area and have sharp antenna directivity, it is necessary to have a strong installation method that will not be affected by slight winds. Conventionally, for example, in the case of installation on a pill roof, concrete d was fixed to a foundation leg C to which a pillar of a laboratory antenna a was fixed (as shown in FIG. 1).

However, there is a drawback in that it is necessary to mix the concrete and it takes a lot of labor and time to properly install it.

Purpose of the Invention The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to omit the most labor-intensive work of mixing concrete, and to simply and firmly install a parabolic antenna using readily available commercially available ready-made products. The present invention provides a parabolic antenna device that can perform the following functions.

Structure of the Invention The parabolic antenna and antenna device according to the present invention includes a plurality of base legs attached to a pedestal that supports a pole having a parabolic antenna fixed to its tip, and a pad formed in a substantially U-shape at the tip of the base leg. The present invention is characterized in that a solid object having a weight capable of supporting and fixing the parabolic antenna is tightened, and the parabolic antenna can be stably installed with simple work.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In FIGS. 2A and 2B and FIG. 3, a parabolic antenna 1 is attached to a pole 2 fixed to a pedestal 3.

Pedestal 3 has four legs 4a and 4b.

4c and 4d (hereinafter legs 4a to 4d are referred to as legs 4) are fastened on all sides with holes 3a, nuts 3b, etc. 5 is a weight, for example, a concrete pavement board may be used.

The required number of weights 5 are attached to the ends of each leg 4 using metal fittings 6 and nuts, and if necessary, at the fixed portion between each leg and the pedestal 3 in the required number of cylinders.

In this embodiment, the mounting bracket 6 is constructed by integrating bolts at both free ends of a U-shaped metal plate, and the bolt portion is passed through a hole in the leg 4 and fastened with a nut 7. Although shown, conversely, the mounting may be done by forming a nut on the metal fitting 6, or by forming a nut holder as a part, and fastening it with a bolt. Note that the weight 5 directly below the pedestal 3 is fixed between the opposing legs 4a, 4c, 4b, and 4d by tightening the metal fittings 6, respectively, as shown in FIG. In the example, the weight of the pavement slab (weight 5) is approximately 17Kg, and the length of leg 4 is 1m, and if two are used at each leg end and in the center, the pole length is 1m, and in the case of a parabolic antenna with a diameter of γ5crn, Can withstand wind speeds up to 60m. If the diameter of the parabolic antenna is large, safe installation can be achieved by adding three or four weights. Further, the number of legs 4 may be other than four, for example, six, and each leg may be provided in the shape of a regular polygon.

Effects of the Invention As described above, according to the present invention, extremely easily available weights can be used even when the working conditions are poor, such as on a rooftop, and it takes a great deal of labor and time to transport the installation machine, concrete, etc. Therefore, the assembly work is extremely easy and can be completed in a short time.
