Description

[Detailed Description of the Invention] This invention relates to an ivy climbing prevention device that prevents ivy from winding around and climbing up a branch line that supports a utility pole.

Ivy that grows on the ground is a climbing plant, so if there is a branch line that supports a utility pole in the area where the ivy grows, it will wrap around the branch line and climb up. Therefore, it is necessary to take measures to prevent ivy from climbing on the branch line.

Many inventions have been made in the past for ivy climbing preventive devices to be attached to branch lines, but all conventional preventive devices have the drawbacks of having complex structures and being difficult to attach to branch lines.

The object of this invention is to solve the above-mentioned drawbacks and to provide a vine climbing prevention device with a simple structure that can be easily attached to a branch line.

The configuration of this invention will be explained below based on the attached drawings.

As shown in FIGS. 2 to 5, the preventive device according to this invention includes a cylindrical body 1 with a smooth surface that fits on the outside of a branch line, an upper end plate 10 attached to the end of this cylindrical body, and a lower end It consists of a combination of a plate 11 and a U-bolt 20 that receives a cylindrical body 1 fitted to a branch line.

The cylindrical body 1 includes a cut-off portion 2 extending in the axial direction, and a fitting groove 5 into which the other side portion 4 can be fitted is formed in one side portion 3 sandwiching the cut-off portion 2 . Serrated engagement teeth 6 and 7 are formed on the inner surface of the fitting groove 5 and one surface of the other side portion 4 corresponding to the inner surface, respectively. These engaging teeth 6, 7 are
The other side portion 4 is allowed to move in the insertion direction with respect to the fitting groove 5, and they engage with each other when moving in the retaining direction.

Now, when the other side portion 4 is fitted into the fitting groove 5 and the engaging teeth 6 and 7 are engaged with each other, the cylindrical body 1 is held in a circular state. Cylindrical body 1 in this circular state
The outer diameter is regulated to a size that does not allow the ivy to wrap around it, and is set at about 90 mm in the example, but may be smaller than the above-mentioned method.

A pair of insertion holes 8 are formed at both ends of the cylindrical body 1 at opposing positions.

The upper end plate 10 and the lower end plate 11 attached to the ends of the cylindrical body 1 are composed of a pair of semicircular bodies 12, 12, and when the pair of semicircular bodies 12 are combined into a circle, one of the abutting surfaces The pin 13 formed in the abutting surface is inserted into the pin insertion hole 14 provided on the other side of the abutting surface and held in a circular state, and the semicircular notch 15 formed at the center of each abutting surface is formed into a circular shape. be done.

A semi-cylindrical portion 16 that can be inserted into the inside of the circular cylinder 1 is provided on the outer periphery of one surface of each semi-circular body 12. This half cylinder part 16 has a cylindrical body 1
A screw hole 17 is provided corresponding to the insertion hole 8, and by screwing the bolt 18 inserted into the insertion hole 8 into the screw hole 17, the cylindrical body 1 and the upper end plate 10 and the cylindrical body 1 and the lower end plate 11 are connected. can be combined.

The U bolt 20 is fitted on the outside of the branch line,
Both ends thereof are inserted into bolt insertion holes (not shown) formed in the seat plate 21, and are fixed to the branch line by tightening nuts 22 screwed onto the ends.

Note that a bent plate portion 23 is formed from the upper and lower edges of the seat plate 21, and a notch 2 for inserting a branch line is formed in this bent plate portion 23.
If you form a U-bolt 20 to the branch line,
It can be installed firmly and stably.

Now, fit the cylindrical body 1 around the branch line 30 to the outside of the branch line 30 so that the branch line 30 shown in FIG.
By inserting the other side 4 of the cylindrical body 1 into the fitting groove 5 and engaging the engaging teeth 6 and 7 with each other, the cylindrical body 1 can be prevented from coming off from the branch line 30.

After the cylindrical body 1 is fitted, the pair of semicircular bodies 12 are assembled into a circular shape at the upper and lower sides sandwiching the cylindrical body 1, and a branch line 30 is inserted into the circular hole formed by the semicircular notch 15. and connect the upper end plate 10 and lower end plate 11 assembled in this way to the branch line 3.
0 towards the cylinder 1 , the half-cylindrical part 16 is inserted inside the cylinder 1 . After insertion, the upper end plate 10 and the lower end plate 11 are rotated to align the screw holes 17 with the insertion holes 8 provided in the cylindrical body 1, and then the bolts 18 are inserted into the insertion holes 8 and screwed into the screw holes. When screwed into 17 and tightened, the cylindrical body 1
An upper end plate 10 and a lower end plate 11 can be attached to the upper and lower ends of.

Further, below the lower end plate 11, a branch line 30
By fitting the U-bolt 20 on the outside of the U-bolt 20, inserting its both ends into the bolt insertion hole of the seat plate 21, and screwing the nut 22 onto the end and tightening,
This U bolt 20 can be attached to the branch line 30, and the U bolt 20 connects the cylindrical body 1 and the upper end plate 10.
and can support the combined body of the lower end plate 11.

As shown in FIG. 1, by attaching the preventive device according to this invention to the branch line 30, even if the ivy wraps around the branch line 30 and starts climbing, the outer diameter of the cylindrical body 1 is such that the ivy cannot wrap around it. Since the size is regulated, the above preventive device can prevent the ivy from climbing.

As described above, in this invention, a cutaway part extending in the axial direction is formed in the cylindrical body, and each of the upper end plate and the lower end plate to be bolted to the end of the cylindrical body is formed by a pair of semicircular bodies. Therefore, the cylindrical body, upper end plate, and lower end plate can be fitted to the outside of this branch line from around the branch line, and the engagement can be achieved by inserting the other side of the cylindrical body into the fitting groove. The cylindrical body can be held in a circular state by engaging the teeth, and the half-cylindrical parts of the upper and lower end plates are inserted into the cylindrical body and bolted, making assembly extremely easy. Moreover, the assembly is strong and separation from the branch line can be reliably prevented. Further, since the surface of the cylindrical body is smooth and the outer diameter is set to such a size that it is impossible for the ivy to wrap around the cylinder, it is possible to reliably prevent the ivy from climbing.

Furthermore, since the U-bolt fitted on the outside of the branch line is attached by tightening the nut screwed onto the end of the U-bolt to receive the combined body of the cylindrical body and the end plate, the combined body can be placed at any position on the branch line. Can be installed on.
