As shown in FIG. 2, the vertical column 22 is composed of an elongated thin plate-shaped iron plate member. Then, as shown in FIG. 1, the upper pressing member 24 is arranged in the longitudinal direction at substantially equal left and right positions, penetrates through the insertion holes 36, and slidably engages with the upper pressing member 24. . The vertical column 22 is not necessarily formed in a thin plate shape, but may be a round bar body, a square bar body,
It may be a pipe member or the like, and the material may be aluminum, copper, other metals, alloys, polyethylene, nylon, polyester or other plastic members or other materials. In addition, the upper pressing member 2 for the vertical column 22
The vertical movement configuration of No. 4 is not limited to the embodiment, and may be a rolling bearing configuration or any other vertical movement configuration.

In FIGS. 1 and 2, a rectangular plate-like connecting member 40 is rotatably and pivotally connected to the lower end of the vertical column 22 via a shaft pin 42. Further, the upper end of the vertical column 22 has a hook shape that is opposite to the bent end direction of the U-shaped bent portion of the upper pressing member 24, that is, is bent to the back side and opens downward in a side view. It has a bent portion 22a. Then, operate this bent portion 22a from the ground,
By engaging the tip of the operating rod 16 having a length of several meters, it is possible to easily and reliably carry and move it to an arbitrary attachment point. That is, since the engagement position is a position that equally divides the longitudinal direction of the main body portion 30, it does not swing in good balance.

On the other hand, in FIGS. 1 and 3, the gold wheel suspension support 1
8 cooperates with the upper pressing member 24 to support the support wire 12 between them.
It is provided with a lower pressing mechanism 26 for sandwiching.
The lower holding mechanism 26 includes a link rod 44 pivotally attached to the vertical column 22 at one end side thereof, and the link rod 44.
A link rod device 48 including an abutting portion 46 which is provided on the other end side of the upper pressing member 24 and rotates or rocks in response to the vertical movement of the upper pressing member 24.

That is, in FIG. 1, the shaft pin 42 is freely rotatably fitted to the lower end portion of the vertical column 22 which slidably engages the substantially central position of the upper pressing member 24 having a rectangular shape in front view. Has been inserted. Link rods 44, 44 are rotatably pivotably attached to the shaft pin 42 at their lower end portions in substantially symmetrical positions so as to form an inverted C shape with the shaft pin 42 as a reference. There is.

On the other hand, on the front side of the main body 30 of the upper pressing member 24, a substantially dog-legged oscillating member 50 is pivoted so as to be positioned substantially symmetrically on both sides of the vertical column 26 as a center. Dress 5
2 is pivotally mounted at its substantially central position. The other end of the link rod 44 is connected to one end of the oscillator 50, that is, the upper left side in FIG.
It is pivotally connected at the
When 2 moves up and down, the link rod 44 whose lower end is pivotally attached to the vertical column 22 moves so as to increase or decrease the open angle of the V-shape.

The rocker 50 and the link rods 44 are provided on the main body portion 30 of the upper pressing member 24 in a pair of left and right. Therefore, the abutting portion 46 is pressed against the support wire on both sides in a well-balanced manner, and the inner support wire is reliably gripped. Here, when the inside of the U-shaped hook-shaped bent portion 28a of the upper pressing member 24 is placed on the support wire 12 and is attached to the support wire 12, and the entire apparatus is set in a free state, the oscillating element 50 oscillates and moves downward. Therefore, the lower side of the support wire 12 is pressed and abutted. In this manner, the oscillating member 50 oscillates around the pivotally connecting portion 52 and presses the portion on the other end side of the pivotally attaching portion 54 against the lower end portion of the support wire 12 or the like, and is internally moved together with the hook-shaped bending portion 28a. The support wire 12 is gripped so as to sandwich it.

The abutting portion 46 is provided on the other end side of the link rod 44 and rotates or swings in response to the vertical movement of the upper pressing member 24 and is synchronized with the movement thereof. Thus, the lower end of the support wire 12 may be contacted and pressed. In this embodiment, the other end side (that is, the upper end side) of the link rod 44 of the link rod device 48 is the upper pressing member 24.
The contact portion 46 is pivotally attached to the main body portion 30 and the contact portion 46 is provided further on the tip side than the pivot portion 52. As in the present embodiment, the oscillating member 50 may be pivotally connected to the upper end side of the link rod 44 and pressed by the oscillating member 50, but as will be described later, simply the upper portions of these link rods are connected. The side may be pivotally attached to the main body portion 30, and the contact portion may be directly formed on the tip end side thereof to be brought into contact with the support wire 12.

As described above, the oscillating member 50 is rotated around the pivotal attachment portion 52, and when the support wire 12 is inserted into the bent portion 28a of the engagement portion 28 and engaged, the upper pressing member 24 is provided.
The support wire 12 is sandwiched between the inner side of the rocker and the upper end side of the oscillating member 50 and pressed, whereby the gold wheel portion 20 suspended on the lower end side is prevented from moving along the support wire. It is to be gripped with various gripping forces.

Further, in the embodiment, the oscillating member 50 is made of urethane at a position where the oscillating member 50 is substantially in contact with the support wire 12 (that is, the outer peripheral edge of the oscillating member 50 on the lower end portion side). A friction member 56 made of rubber or the like is attached. As a result, together with the friction member 34 on the inner side of the bent portion 28a of the engaging portion 28, the contact portion of the supporting wire 12 is engaged so as to wrap almost all in the circumferential direction, resulting in static friction. The force is further increased and the fastening force is greatly increased. In addition, the support line 12 is not attached with scratches or the like.

As shown in FIG. 1, in the embodiment, the bent portion 28a of the engaging portion 28 is formed with the dogleg-shaped recess of the oscillating member 50 facing downward, that is, with both ends facing downward.
It is installed in the most separated state from the inner surface side, therefore,
As shown in FIGS. 3 and 5, the friction member 56 is attached near the right end side of the dogleg in the state where the oscillating member 50 is most separated.

As shown in FIG. 5, the upper end side 5 of the oscillator 50 is
0a has a substantially oval shape, and has a thickness corresponding to a substantially support wire diameter. In short, if it is formed in an arc shape, when the oscillating element 50 rotates, it is smoothly pressed against the lower side of the support wire 12 to perform the abutting action. As described above, the central position of the rocker 50 in the shape of a dogleg is attached to the pivot portion 5.
In FIG. 2, the main body portion 30 is pivotally attached to the main body portion 30, and the above-mentioned friction member 56 made of urethane rubber or the like is fixed to the peripheral edge of the upper end side 50a thereof. This cooperates with the friction member 34 of the engaging portion 28 of the upper pressing member 24 to generate a stronger static friction force. Also, even if it is attached to a soft support wire such as an aluminum steel stranded wire formed of an aluminum alloy as a material, the support wire surface is not scraped off because it does not slip and does not slip. It can be used for soft and hard supporting wires.

Furthermore, in the figure, the rocker 5 having a dogleg shape is shown.
On the lower end side of 0 (that is, the other end side away from the mounting position of the friction member 56), a stepped portion 58 is formed from the upper end side 50a of the egg shape, and a thin piece 60 is connected and formed. And
The upper end of the link rod 44 is pivotally attached to the thin piece 60 so as to be freely rotatable. The link rod 44 is pivotally attached to the back surface side of the thin piece 60 in FIG. 5, but when the left oscillating member 50 rotates clockwise in the drawing, for example, the step portion 58 is formed.
Serves as a stopper to prevent the rocker 50 from further rotating beyond the link rod 44 from the state shown in FIG.

An end portion side different from the contact side of the dogleg shaped oscillating member 50, that is, when the oscillating member 50 is rotated to bring its upper end into contact with the lower surface side of the support wire 12, An end of a long plate-like link rod 44 is rotatably and pivotally connected to the lower end side. The lower end of the link rod 44 is the vertical column 2
It is rotatably supported by a shaft pin 42 at the lower end of 2.
Therefore, the vertical column 22 is attached to the shaft pin 42 at the lower end of the vertical column.
The connecting member 40 and the left and right link rods 44 are pivotally attached to the same shaft in a free-wheeling manner. At this time, both link rods 44 are installed so as to be open in an inverted V shape with respect to the vertical column 22.

When the support wire 12 is attached to the attachment portion 28 of the upper pressing member 24 to free the main body of the apparatus,
That is, the bending portion 28 of the engaging portion 28 with respect to the support wire 12
In a state where the inner surface side is placed on and separated from each other, the shaft pin 42 portion is pulled downward by its own weight or the load of the cable 14, and both link rods 44 are displaced so that the sandwiching angle between them is reduced, As a result, the oscillating member 50 rotates around the pivot portion 52, and the upper end side of the oscillating member 50 is pressed and brought into contact with the lower side of the support wire 12.

As shown in the figure, both of these link rods 44
A spring 62 that urges the link rods 44 in a direction that narrows the included angle of the link rods 44 is stretched between the gaps sandwiched between them. This spring 62 constantly urges the upper end side of the oscillating member 50 in the direction in which it abuts against the lower surface side of the supporting wire, and therefore, the abutment of the oscillating member 50 to the supporting wire 12 is released.
