JP2002233254A - Tree climbing tool for pruning - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve problems that a tree climbing tool used for pruning, etc., has bad production cost and operating efficiency and transportation to the destination is a great burden on an operator because the climbing tool has a complicated structure and is heavy. SOLUTION: The tree climbing tools are obtained by winding tightening ropes having a difference in length around a living tree. Alternate movement can readily be made and ascending and descending can be carried out by using a pair of the left and right tree climbing tools for pruning. The transportation to the destination becomes easy due to light weight thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree climbing tool used for easily and efficiently performing a pruning operation on a tree.

[0002]

2. Description of the Related Art Conventional pruning tree climbing equipment has a complicated structure, is difficult to handle, and is heavy, so that work efficiency and transportation to a destination place a heavy burden on workers and have been regarded as a problem.

[0003]

The problem to be solved is that the conventional climbing tool has a complicated structure, so that the production cost is high and the working efficiency is low.

[0004] Therefore, the present invention reduces the production cost,
Another object of the present invention is to improve the efficiency of pruning work by being lightweight and easy to carry and climb trees.

[0005]

According to a first aspect of the present invention, an upper fastening rope is connected to a lower footrest, and the foot is placed on the footrest so that the fastening rope is connected to a standing tree. It is characterized by its small size and light weight, which can be moved up and down by a pair of left and right sides by tightly adhering to the outer periphery of the.
The invention according to claim 2 is characterized in that the footrest is provided with an angle at the contact portion of the standing tree so that contact between the two tightening ropes is eliminated and smooth climbing is enabled. It is a device.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view in which the footrest 3 of FIG. 3 is connected to the tightening rope 1 of FIG. 2, and FIG. 2 is a left and right footrest 3 of FIG.
FIG. 3 is a perspective view of a footrest 3 in one embodiment of a pruning tree climbing device, and FIG. 4 is a side view showing a method of use.

In FIG. 2, the material of the fastening ropes 1 and 2 is, for example, φ2 mm depending on the type of the standing tree 4 in FIG.
A cord, a rope, a rope (wire, natural fiber, synthetic fiber, synthetic fiber-coated rope) having a diameter of up to 30 mm is selected.

Further, the diameter of the ring E (all the rings of the tightening ropes 1 and 2) is set to be large enough to allow the tip of the tightening rope to pass through and to allow the connecting portion L shown in FIG.

The terminal F of the rope of the fastening ropes 1 and 2
The processing method is any of eye compression processing, splice eye compression processing, winding processing, ice splicing processing, and flemish processing, depending on the type of the tightening rope.

Therefore, since both ends of the fastening ropes 1 and 2 have the same shape, either side of the winding side around the standing tree 4 or the side connecting to the footrest 3 may be used.

Next, the lengths of the tightening ropes 1 and 2 and the stride of climbing will be described. When the length of the tightening rope 1 is 1,500 mm and the stride of climbing is 300 mm, for example, the diameter of the standing tree 4 is 200 mm. When the outer circumference of the trunk is 628 mm (diameter 200 mm × circumference 3.14), the length of the tightening rope 2 is 1,200 mm (when the stride is 300 mm, the length of the tightening rope 1 is 1,5.
00 mm-300 mm).

In FIG. 3, the material of the footrest 3 is 6 in diameter.
The joint is welded with a round bar of 12 mm (made of steel or stainless steel). The dimension of G in FIG. 3 is 280 mm,
Considering the size of the shoes of the worker, the dimensions of H are preferably around 200 mm because of the close contact, and the dimensions of J are around 100 mm. The connecting portion L allows the fastening ropes 1 and 2 to be attached and detached. Become.

In FIG. 4, an angle K (70
°), the weight is applied to the footrest 3
The bottom surface M becomes horizontal, and at the same time, a gap N (50 mm) is generated between the standing tree 4 and the footrest portion 3, so that the tightening rope 1 and the tightening rope 2 do not come into contact with each other, so that the vertical movement P is possible.

The present invention is realized by connecting the tightening ropes 1 and 2 shown in FIG. 2 with a difference in the stride of the ascending and descending steps to the footrest portion 3 and forming a pair thereof.

The method of using the present invention constructed as described above will be described according to function. The fastening rope 1 shown in FIG. 2 is turned from the right to the outer periphery of the standing tree 4, the tip B is passed through the loop A, and the foot B is attached to the tip B. The mounting part 3 is connected. Next, the fastening rope 2 is turned below the fastening rope 1 from the left side of the outer circumference of the standing tree 4, the tip D is passed through the loop C, and the footrest 3 is connected to the tip D.

The method of using the present invention constituted as described above will be described according to functions with reference to FIG.
Is pulled downward with the weight on the footrest 3,
The fastening ropes 1 and 2 are fixed to the outer periphery of the standing tree 4 in close contact.

When moving up and down, the weight should be
If it is hung, a gap is formed on the outer circumference of the fastening rope 2 and the standing tree 4, and the fastening rope 2 can move up and down. Next, hang the weight on the left footrest 3 and tighten the rope 1 and the standing tree 4
A gap is formed in the outer periphery of the rope, and the tightening rope 1 can move up and down. When one is fixed in this manner, the other can be moved up and down, and can be easily moved up and down by repeating this operation.

[0019]

As described above, according to the present invention, since the structure is simple, the production cost is reduced and the working efficiency is improved, and the transportation to the destination is facilitated due to its light weight. .
