Description

[Detailed description of the invention] "Industrial field of application" This invention relates to an antenna branch line stopper for attaching the branch line supporting the antenna to a beam of a building when the antenna is installed on a roof or the like. .

``Prior Art'' Conventionally, as shown in FIG.
03 and install it on the roof. At this time, in order to support the mast 102 provided with the antenna 101, one end of the branch line 104 is fixed to the center of the mast 102, and the other end is attached to a beam 105 of the building etc. via an antenna branch line stopper A.

As shown in FIGS. 5 and 6, the antenna branch wire stopper A has rings 112 and 112 at both ends of the wire 111, respectively.
113 and the end of the wire 111 is a cylindrical metal 1
Caulk with a tool using 14 and 114. one ring 1
A holding cylinder 115 is fitted into the holding cylinder 115, and the ring 112 is rotatably held in an annular groove 116 on the outer periphery of the holding cylinder 115.
A nail 117 is inserted into the holding cylinder 115, and a packing 118 is fitted from the tip of the nail 117. The other ring 113 and the center of the wire 111 are protected by a protective tube 119,
120.

As shown in FIG. 7, the antenna branch line fastener A connects the branch line 104 to a ring 113 at the other end by nailing a nail 117 at one end to a beam 105 of the building.
At this time, when nailing the antenna branch line fastener A to the beam 105, the nail 117 is nailed from the ground using a ladder, and the other end is placed on the roof. Then, the wire 111 hangs downward from near the nail 117 due to its own weight, and when working on the roof to connect the branch line 104 and the branch line stopper A, the wire 111 leans out from the edge of the roof and pulls the branch line stopper A. .

``Problem that the invention attempts to solve'' This invention solves the problem that the antenna branch wire stopper, which has one end attached to a roof beam and the other end placed on the roof, sag due to the weight of the wire, causing the antenna branch wire on the roof to sag. When connecting the antenna to the antenna branch line stopper, it is extremely dangerous because the operator is leaning over the edge of the roof and pulling the branch line stopper.

``Means that the invention attempts to solve'' Therefore, in view of the above circumstances, this invention aims to make work on the roof as safe as possible.
An antenna branch line stopper that attaches one end of a wire to a building, etc. and connects the other end to a branch line that supports the antenna, and is a stopper that is inserted into a gap between roof tiles to prevent the antenna branch line stopper from hanging above the roof due to its own weight. The antenna branch line stopper, which has a slidable member, is held on the roof so that it does not hang down from the beam.

``Operation'' A stop member slidably attached to the wire is sandwiched between roof tiles, etc., and the connecting portion of the antenna branch line stopper to the antenna branch line is held and placed on the roof.

"Example" As shown in Fig. 1, the antenna branch line stopper is
Rings 2 and 3 are formed at both ends of the wire 1, and the ends of the wire 1 are caulked with a tool using cylindrical metals 4 and 4. A holding cylinder 5 is fitted into one ring 2, and the ring 2 is rotatably held in an annular groove 6 on the outer periphery of the holding cylinder 5. A nail 15 is inserted into the holding cylinder 5, and a gasket 1 is inserted from the tip of the nail 15.
Insert 6. The other ring 3 and the central part of the wire 1 are covered with protective tubes 17 and 18.

A stop plate 21 made of synthetic resin or metal is slidably fitted to the center of the wire 1 so that the antenna branch line stop does not hang down from the roof due to its own weight. The through hole 22 of the stop plate 21 is set to be larger than the outer diameter of the protective tube 18 and to prevent the wire 1 from falling out from both ends. The stop plate 21 may be any material such as roof tiles, as long as it can be easily inserted into the gap and will not be damaged.

The antenna branch line stopper is as shown in Figure 2.
From the top of the ladder, connect the nail 15 at one end to the beam 31 of the building.
Then, the stop plate 21 of the wire 1 is slid and inserted into the tile 32 at a position where it can be easily inserted into the tile 32, and the antenna branch line connecting part of the antenna branch line stopper is placed and held on the roof. Next, climb onto the roof and hold the antenna, and connect the antenna branch line 33 to the ring 3 of the stopper.

As a stop member, a third stop plate 21 is used instead of the above stop plate 21.
As shown in the figure, a wire 41 may be slidably provided on the wire 1.

``Effects of the invention'' As mentioned above, this invention provides a slidable stopper on the wire, and when attaching one end of the wire to a beam of a building, the stopper is inserted into a roof tile at the same time. The connecting part of the stopper to the branch line can be placed and held on the roof, and there is no need to lean out from the roof to pull the stopper that hangs down from one end, making it extremely easy to connect the stopper to the branch line. It's safe. Furthermore, since the stop plate, wire, etc. are slidably provided, it is easy to implement and inexpensive.
