Description

[Detailed description of the invention] [Field of industrial application] The present invention is a scissors such as Takabra scissors, in which the scissors attached to the tip of the long handle are opened and closed by a handle provided on the proximal side of the long handle. This invention relates to a swinging device.

[Prior art]

Tall branch shears, which are used to pick fruits such as apples from trees or to prune other tree branches, usually have the shears attached to the tip of a long handle, and are operated by a handle on the hand side. This opens and closes the rod by pushing and pulling the rod passed through the handle.

[Problem that the invention attempts to solve]

However, as disclosed in Japanese Utility Model Publication No. 56-33261 and Japanese Utility Model Application Publication No. 57-119673, this type of scissors has both the scissors and the handle on the hand side held at a constant angle with respect to the long handle. It is connected. This causes the following inconveniences. In other words, the branches of trees that are targeted by the above-mentioned high branch shears overhang from the trunk in all directions, including not only vertically and horizontally but also diagonally. Therefore, when using the high branch shears, it is necessary to It is necessary to adjust the angle of the scissors to correspond to the direction of the branch to be pruned while determining the direction in which the scissors protrude, so adjust the direction (angle) of the scissors while twisting the wrists of the hand that holds the handle and the hand that operates the handle. must be changed each time, making the operation cumbersome.

In addition, although tall branch shears are suitable for cutting tree branches, they are structurally unsuitable for use on the ground, such as cutting lawns, so their use is narrowly limited. It's getting old.

In view of the above points, the present invention has been developed by attaching the scissors to the long handle by bending the scissors, and by making the scissors swingable relative to the long handle, thereby ensuring ease of work and providing versatility. The present invention provides scissors that can be used for various purposes.

[Means to solve the problem]

The present invention connects a base tube for connection to a long handle and a support tube having scissors at its tip at a predetermined bending angle through an elbow-shaped joint body, and connects the support tube to its axis at the joint body. It features a scissors swinging device attached to a long handle that can rotate 180 degrees around the center.

[Effect]

According to the above means, when the base tube is connected to the long handle and the scissors are attached, by rotating the support tube with respect to the base tube, the relative posture of the scissors with respect to the handle on the hand side of the long handle is adjusted. Because it can be changed, it can be used for pruning tree branches, mowing the lawn, etc. without having to twist the wrists of both hands holding the long handle and handle to change the angle of the handle and scissors each time. You can work by applying the scissors to these branches and grass at the desired angle.

Since the scissors are bent with respect to the long handle by means of an elbow-shaped joint, the scissors can be inserted into trees and pruned by swinging the shears.

In addition, because of the presence of the elbow-shaped joint, the scissors can be run parallel to the ground in a natural state with the long handle diagonally lowered to the ground, making it easier to mow the lawn.

Furthermore, when mowing the lawn, by swinging the scissors, it is possible to cut the edges of the lawn with the shears in an upright position, instead of laying the shears on their side and cutting the grass to the same height.

〔Example〕

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

As shown in FIG. 1, the swinging device has a base tube 1 for connection to a long handle, and a support tube 3 having scissors 2 at its tip, bent at a predetermined angle by means of an elbow-shaped joint body 4. Connected. That is, the elbow-shaped joint body is a hollow body, and the base cylinder 1 is inserted into one socket 5 and fixed with screws 6. Further, the support tube 3 is inserted into the other socket 7, and the support tube 3 can be rotated 180 degrees around its axis. For this reason,
A long groove 8 is carved in the socket 7 over an angular range of 180 degrees, and a stopper screw 9 is inserted into the support tube 3 through this groove.
is screwed in, and the movement of this stopper screw 9 within the long groove 8 restricts the rotation range of the support tube. 10 is a synthetic resin sleeve fitted over the support tube 3, and by generating an appropriate frictional force between it and the socket 7, which is an aluminum member,
The support tube 3 is rotated relative to the elbow-shaped joint body 4 so that the support tube 3 can be fixed at an appropriate position. Although not shown in the drawings, rotation of the support tube 3 relative to the socket 7 may be restricted by providing a corrugated ridge for positioning the screw at a suitable position on the inner surface of the long groove 8 in contact with the screw 9.

The scissors 2 consists of a fixed blade 11 and a movable blade 12. The fixed blade 11 is fixedly connected to the support tube 3 with a bolt/nut 13, and the movable blade 12 is attached to the fixed blade 11 with a pivot 14. In addition, the fixed blade 11 and the movable blade 12
Base plates 15 and 16 made of plastic are screwed to one side of each blade body. These base plates 1
Numerals 5 and 16 have contact surfaces that come into contact with each other when the scissors 2 are closed, and the contact surfaces are each formed into an uneven rough surface, and the base plate 16 on the side of the movable blade 12 is set back from the cutting edge. It is installed so that it is located in the same position.

A triangular link 18 that rotates by a pivot pin 17 is attached to the inside of the bent portion of the elbow-shaped joint body 4, and rods 19 and 20 that pass through the base tube 1 and the support tube 3, respectively, are connected to this. Ru. The rod 19 that passes through the base tube 1 connects the base tube to the elongated handle 2 shown in FIG.
1, it is connected to an operating rod (not shown) in the long handle, and the operating force of the handle 22 on the proximal side of the long handle is input. The rod 20 inserted through the support tube 3 transmits the push and pull force acting on the rod to the movable blade 12 to open and close the scissors 2. Since the support tube 3 is rotated with respect to the elbow-shaped joint body 4, both ends of the rod 20 are screwed to the triangular link 18 and the mounting brackets 23 and 24 of the movable blade 12, so that the rod 20 is twisted during the rotation. I try not to.

With this configuration, the elbow-shaped joint body 4
By rotating the support tube 3 against the long handle 2
1 is fixed in a constant posture, the posture shown in Figure 3 and the position shown in Figure 4 are
The scissors 2 can be oscillated in a range of 180 degrees including the figure posture. Therefore, when pruning the branches of a tree, if you use the scissors 2 by swinging them in accordance with the direction of the branch you are trying to prune while determining the direction in which each branch extends, the elongated handle 21 side The handle 22 can be operated without changing the posture of the handle 22. In particular, since the scissors 2 have a predetermined bending angle with respect to the base tube 1, that is, the long handle 21, by means of the elbow-shaped joint body 4, the scissors 2 is bent at a predetermined angle with respect to the base tube 1, that is, the long handle 21. It is possible to prune by inserting scissors into the back side of the tree.

Moreover, conventional high branch shears cannot be used for mowing lawns, but according to the shears according to the present invention, since the scissors according to the present invention have the elbow-shaped joint body 4, the operator can move the long handle 21 to the ground A. On the other hand, since the scissors 2 can be positioned parallel to the ground A as shown in FIG. 5 in the diagonal natural working posture, mowing the lawn can be easily performed.
At this time, as seen in the figure, the thick base plate 1 of scissors 2
By placing the blades 5 and 16 on the lower side, the ground height of the fixed blade 11 and the movable blade 12 can be maintained constant by the base plates 15 and 16 regardless of the undulations of the ground. It is possible to cut the grass to a constant height. Furthermore, when cutting the edges of the lawn, it can be done by standing the scissors 2 against the ground as shown in FIG.

〔effect〕

As detailed above, according to the present invention, the shears can be placed along the branch to be pruned without holding the long handle and twisting the hand operating the handle, making pruning work easier. becomes. In addition, by adopting the elbow-shaped joint body, the scissors can be placed along the ground, so it can be used for lawn mowing work, etc., increasing the range of applications.
