Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a messenger wire attachment device for public listening equipment.

Generally, as this type of device, the one shown in FIG. 1 is known. In Fig. 1, reference numeral 1 denotes a housing of the public listening equipment, and a mounting base 2 having a V-groove is fixed to the upper part of the housing, and a messenger wire press fitting having a V-groove is attached to the mounting base 2. 3 is attached with bolts 4. Reference numeral 5 denotes a messenger wire, which is fitted into the V groove of the mounting base 2 and the V groove of the pressing metal fitting 3, and is connected to the mounting base 2 by the pressing metal fitting 3 in the V groove by tightening the bolt. It is strongly pressed and fixed to the mounting base 2 by this pressing. Note that 6 is a spring washer into which the bolt 3 is inserted.

By the way, since the above-mentioned messenger wire 5 is installed on a telephone pole, the installation work becomes difficult when the above-mentioned public listening equipment is a heavy equipment weighing 7 to 8 kg, such as a mains amplifier. Become. That is,
The user must carry the above-mentioned casing 1 on his arm to the top of the telephone pole, support the casing 1 with one hand on the telephone pole, and tighten the bolt 4 with one hand in this state.

The present invention provides a messenger wire attachment device for public listening equipment that eliminates the above-mentioned drawbacks and is easy to install.

An embodiment of the present invention will be described in detail below with reference to FIGS. 2 and 3. In FIG. 2, reference numeral 1 denotes a housing of the above-mentioned public listening equipment, and mounting stands 7a, 7b are fixed to the housing.
A metal fitting 9 made of iron is fixed to 7b with bolts 8a and 8b. This metal fitting 9 is the mounting base 7 mentioned above.
It has a bridge-shaped handle part 10 extending from a to 7b, and a pair of hanging parts 11a and 11b formed by being bent into a hook shape at both ends of the handle part 10, and these hanging parts 11a and 11b are connected to the housing. A vertical part 16 extends perpendicularly to the housing 1 and includes a pressing surface 15 of the messenger wire 5, and a vertical part 16 extends parallel to the housing 1 from the upper end of the vertical part 16 so that the pressing surface 15 is on the inside. It extends from the horizontal part 17. Pressing fittings 13a and 13b are attached to the vertical parts 16 of the hanging parts 11a and 11b by bolts 12a and 12b, respectively.

Since the messenger wire attachment device for public listening equipment described above has the handle part 10, it is easy to carry the housing 1 to the top of the utility pole, and the hanging parts 11a, 11
By suspending the casing 1 from the messenger wire 5 by means of b, there is no need to support the casing 1 with one hand as in the conventional case. Also, in this suspended state, the bolt 12
When the screws 11a and 12b are tightened, the messenger wire 5, which has come into contact with the horizontal portion 17 of the hanging portions 11a and 11b, is moved by the pressing fittings 13a and 13b to the hanging portions 11a and 12b.
By pressing against the pressing surface 15 of 11b, the housing 1 can be fixed to the messenger wire 5. The pressing state of the messenger wire 5 by the press fittings 13a and 13b is shown in an enlarged scale in FIG. 3 with respect to the press fitting 13a.

As described above, in the present invention, since the housing 1 is provided with the handle part 10 and the hanging parts 11a and 11b, the work of attaching the housing 1 to the messenger wire 5 is facilitated, and especially when the housing 1 is suspended, Since it can be fixed to the messenger wire 5 with a press fitting in this state, the installation work becomes even easier. Moreover, the handle part 10 and the hanging part 1
1a, 11b are formed of metal fittings 9, and the messenger wire 5 is attached to the metal fittings 13a, 1.
3b, the fixing means, the handle portion 10, and the hanging portions 11a, 11b can be easily constructed.
