Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a parabolic antenna flexible installation used when installing a parabolic antenna used to receive satellite broadcasting at a predetermined position such as the roof or wall of a building. The present invention relates to a pedestal, and particularly to a pedestal for freely installing a parabolic antenna, which has a sturdy structure using a dogleg-shaped reinforcing plate.

(B) Prior art Figure 1 is a perspective view of a parabolic antenna flexible mounting base (Utility Application No. 58-173589, Publication of Utility Model Application No. 60-79810), which was previously filed by the applicant. Consists of left and right support legs b, c, base support rod d, leg support rod e, and left and right mounting rods f, g,
Attach the upper ends of the left and right support legs b and c to the tip of the installation base a, and attach the rear end of the installation base a to the base support rod d, and attach the lower ends of the left and right support legs b and c to the leg support rod e. attached to the base support rod d
and leg support rods e are attached to appropriate positions of mounting rods f and g.

However, in this parabolic antenna flexible mounting frame, the mounting of the mounting base a and the left and right support legs b and c is unstable and weak, so that when the parabolic antenna is mounted on the support tube h of the mounting base a, There was a weak point.

(c) Purpose This invention was made to improve the above-mentioned drawbacks, and it is possible to make the attachment of the left and right support legs and the installation base more sturdy, eliminate structural instability, and maintain strong support. The main purpose is to provide a stand for freely mounting a parabolic antenna.

(D) Structure The present invention consists of an installation base having a U-shaped cross section with a support tube erected on its upper surface, left and right support legs integrally attached to the front end of the installation base with bolts, nuts, etc. The parabolic antenna flexible mounting frame is provided with a dogleg-shaped reinforcing plate for reinforcing the mounting location, a base support rod attached to the rear end of the installation base, and leg support rods attached to the lower ends of the left and right support rods. Then, fit the upper narrow part of the doglegged reinforcing plate into the left and right walls of the front end of the installation base having a U-shaped cross section so that both ends are brought into close contact with the left and right walls, and the lower wide part of the doglegged reinforcing plate. The parabolic antenna flexible mounting frame is characterized in that the parabolic antenna is fixed to the upper front side surfaces of the left and right support legs to attach the parabolic antenna to the support tube of the installation base.

(e) Embodiment In FIG. 2, reference numeral 1 denotes an installation frame having a U-shaped cross section, with a parabolic antenna support tube 2 erected at the front end, and circular holes 3, 3, 3 provided in the midsection. Mounting holes (not shown) are formed at the tips of both walls, and 4 and 5 are left and right support legs,
It is formed of an L-shaped rod, each having a left-right symmetrical open leg shape, and stopper holes (not shown) are provided at the upper and lower ends of the inner side wall.

Reference numeral 6 denotes an L-shaped base support rod, which has elongated holes 7, 7, . Reference numeral 9 denotes an L-shaped leg support rod, which has elongated holes 10, 10, .

As shown in FIG. 3, the front end of the installation base 1, which has a U-shaped cross section, and the upper ends of the left and right support legs 4, 5,
A long bolt 12 is inserted into the mounting hole and the fixing hole from the right outer side, and a nut (not shown) is screwed onto the left outer side. In this installation, in the present invention, as shown in FIGS. 3 and 4, a doglegged reinforcing plate 13 is used, and the upper narrow part of the doglegged reinforcing plate 13 is connected to the installation base having a U-shaped cross section. The reinforcing plate is fitted between the left and right walls 14, 14 of 1, so that both ends thereof are brought into close contact with the left and right walls, and mounting holes (not shown) are formed near both ends of the lower wide portion of the dogleg-shaped reinforcing plate. Mounting holes at the top of the left and right support legs 4 and 5 (not shown)
The V-shaped reinforcing plate 13 is fixed to the upper parts of the left and right support legs 4 and 5 by passing a bolt 15 through the rear side and screwing a nut 16 on the front side.

As shown in FIG. 2, the rear end of the installation base 1 is attached to the base support pieces 8, 8 of the base support rod 6 with long bolts 12 and nuts (not shown). The lower ends of the left and right support legs 4 and 5 are leg support rods 9.
Bolts 17 and nuts 18 are attached to the leg support pieces 11, 11.
It is attached at.

Parabolic antenna flexible installation mount A in Figure 2
is attached to a wall B of a building as shown in FIG. 5, and a parabolic antenna C shown by a chain line is installed on a support tube 2.

In addition, when installing a parabolic antenna on the roof, as shown in FIGS. 6 and 7, the support legs 4 and 5 are spread forward, and the leg support rods 9 and the base support rods 6 are attached to the mounting rods 19 and 20. Place it on the left and right long slots 7, 7, 1.
0, 10 are holes 21, 21, 2 of mounting rods 19, 20
2 and 22, and attach them to the appropriate locations using bolts 23 and nuts 24. Then, place it on the roof D, fix it, and attach the parabolic antenna C to the support tube 2.
to be installed.

(F) Effects As described above, the present invention has the upper narrow part of the doglegged reinforcing plate fitted into the left and right walls of the installation base having a U-shaped cross section so that both ends are brought into close contact with the left and right walls. Since the vicinity of both ends of the lower wide portion of the letter-shaped reinforcing plate is fixed to the upper front side surfaces of the left and right support legs, when attaching the left and right support legs to the installation frame having a U-shaped cross section using bolts, nuts, etc. The left and right walls of the installation frame are blocked by the V-shaped reinforcing plates, so they do not bend inward even when tightening fixtures such as bolts and nuts, and the left and right support legs are connected and fixed to each other by the V-shaped reinforcing plates. Therefore, it has a sturdy structure, and double reinforcement can be achieved with a single dog-shaped reinforcing plate.
This has the effect of firmly holding the parabolic antenna installed in the support tube.
