A support frame 2 whose cross section is L-shaped comprising a support piece 13 and a connection piece 14 is assembled to the mount frame 1 by using a mount screw 22 whose tip is threaded to the receiving support piece 7 through the connection piece 14. A support 80 is held between the support piece 13 of the support frame 2 and the clamp frame 3 and a tip of a tightening screw 26 whose head is locked to the clamp frame 3 is threaded to the support piece 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting an antenna support for mounting an antenna of a radio base station on a side wall of a public telephone box or the like (hereinafter simply referred to as a telephone box).

[0002]

2. Description of the Related Art In recent years, car phones and mobile phones have become widespread as public mobile communication systems.

A radio base station of such a mobile communication system is usually installed in a telephone station, and installation and maintenance of the device are expensive.

On the other hand, a simple mobile phone system is being studied as a system that can provide public communication at a lower cost than conventional mobile phones. In this system, since the transmission power is smaller than that of the conventional wireless communication system, the wireless zone per wireless base station is narrowed, and as a result, the number of wireless base stations in the service area is inevitably increased. Will increase. Therefore, it is indispensable to install a wireless base station on a side wall of a building, a telephone box, or the like. Therefore, downsizing of equipment by downsizing the wireless base station device and antitheft measures are also required.

The present invention provides a device for mounting a transmitting / receiving antenna of a radio base station in a public telephone box in a radio communication system such as the above-mentioned simple mobile phone.

[Means for Solving the Problems] A mounting frame having an L-shaped cross section composed of a mounting portion and a receiving and supporting portion is screwed onto the mounting portion with a tip of a mounting screw through a wall material such as a public telephone box. A support frame projecting from the box and having an L-shaped cross section composed of a supporting piece and a connecting piece is assembled to the mounting frame with an assembling screw having a tip screwed to the receiving and supporting piece through the connecting piece. Hold the support with the support piece of the support frame and the holding frame,
The tip of a tightening screw whose head is locked to the holding frame is screwed to the support piece.

1 is a longitudinal sectional view, FIG. 2 is a partially cutaway plan view with the telephone box side omitted, and FIG. 2 is a sectional view taken along the line aa in FIG. 2, and FIG. 4 is an exploded perspective view of the main members of the present invention.

In the embodiment, the mounting frame 1 and the supporting frame 2 are assembled to each other, and the supporting frame 2 and the holding frame 3 form the antenna column 80.
And the mounting frame 1 is projected on the outer wall Bw of the public telephone box B interposed between the seat plate 4 and the mounting frame 1.

The mounting frame 1 is composed of an L-shaped section having a vertically arranged mounting piece 6 and a laterally arranged receiving / supporting piece 7, and is provided at the center of the mounting piece 6 in the lateral width direction for electric wires. Through holes 8 are provided, and through holes 9 and 9 for tool insertion are provided on the left and right sides of the through holes 8, and nut members 10 and 10 are fixed to the outer surface of the mounting part piece 6 and the lower surface of the receiving and supporting part piece 7, respectively. First and second screw holes 11 and 12 are provided in the respective pieces 6 and 7.

Numeral 7a is a reinforcing piece provided on both sides of the receiving and supporting piece 7.

The support frame 2 includes a support piece 13 and a connecting piece 14.
And a nut member 10, 10 fixed to the outer surface side of the supporting piece 13 arranged in the longitudinal direction, the nut member 10, 10 corresponding to the through holes 9, 9, 15
Is provided in the lateral direction, and the connecting piece 14 arranged in the lateral direction is provided with a long hole 16 that is long in the inner and outer directions so as to correspond to the second screw hole 12.
Are provided on both sides of each of the pieces 13 and 14, and the reinforcing piece 13a,
14a is provided.

The holding frame 3 has a U-shaped cross section in which a central piece 19 is provided between an upper piece 17 and a lower piece 18, and extends from the central portion of the central piece 19 to the central portions of the upper and lower pieces 17, 18. While the fitting notch 20 of the antenna support column 80 is provided as a notch, a through hole 21 having a smaller diameter on the upper side is provided at a position corresponding to the screw hole 15 of the central piece 19.

The seat plate 4 is made of a flat plate and has a through hole 23 corresponding to the through hole 8 in the center and a through hole 24 corresponding to the first screw hole 11 on the left and right.

Therefore, while confirming the separation width between the mounting portion piece 6 and the support portion piece 13, the positions of the mounting portion piece 6 and the supporting portion piece 13 are adjusted by using the elongated holes 16, and the assembling screw 22 penetrated through the elongated holes 22. The mounting frame 1 and the support frame 2 are connected to each other by screwing the tip of the to the second screw hole 12, and the antenna support 80 is engaged with the fitting notch 20 of the holding frame 3, while the central part of the holding frame 3 is engaged. After assembling the tip of the tightening screw 26 penetrating the through hole 21 of 19 into the screw hole 15 and assembling the antenna support 80 to these,
The first screw hole provided in the mounting portion 6 of the mounting frame 1 at the tip of the mounting screw 25 inserted through the through hole 24 of the seat plate 4 along the inner surface of the outer wall at the attic position after the roof of the telephone box is once removed. When the screw is tightened to 11 and the roof is reattached, the attachment of the antenna column 80 to the outer wall Bw at the attic position of the telephone box B is completed.

[0015]

As described above, since it is compact in structure as described above, it can be provided at a low cost, and it can be easily attached to the upper outer wall of a telephone box or the like, and after the attachment, loosen the assembling screw and the tightening screw from the outside. Since there is no means to remove it, it is practical because it can prevent theft.
