Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a lawn mower for cutting weeds, etc.
Especially regarding lawn mowers for mowing lawns.

(Prior Art) Conventionally, lawns have been cut by using a mechanical lawn mower or by using a sickle or the like.

(Problems to be Solved by the Invention) However, mechanical lawn mowers have drawbacks such as difficulty in mowing grass in narrow spaces and high manufacturing costs. Furthermore, when mowing the lawn with a sickle or the like, it is necessary to sit down and move the sickle constantly, which causes back pain and arm fatigue. In view of the above-mentioned drawbacks of the prior art, the present invention allows mowing work to be easily carried out in narrow spaces, and also eliminates the need for constantly moving the arm or sitting down to mow the lawn. The purpose is to provide a mowing machine.

(Means for Solving the Problems) In order to achieve the above object, the lawn mower of the present invention includes a handle, an elastic body fixed to the handle, and a mower that is swingable to the handle via the elastic body. The blade part is connected to the blade part.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 is a perspective view of a lawn mower according to the present invention, Figure 2 is a perspective view of a lawn mower according to the present invention;
The figure is a partial sectional view of the front view of FIG. 1, and FIG. 3 is a perspective view of another embodiment.

As shown in FIGS. 1 and 2, the handle 1 is formed into a cylindrical rod shape. A spring 2, which is an elastic body, is inserted into the lower end of the handle 1, and the upper end of the spring 2 is fixed to the handle 1 with a fixing material 4. In addition, a bottom surface 5a is provided at the lower end of the handle 1.
A hollow cylindrical rocking member 5 is provided. The swing member 5 is fixed to the spring 2 by pressing a bolt 6 screwed onto the side surface of the swing member 5 against the spring 2. A blade portion 3 having cutting blades 3a formed on both sides thereof is fixed to the bottom surface 5a of the rocking member 5 via a connecting member 7.

Next, the operation of this embodiment will be explained. When you hold the handle 1 of this lawn mower and move the handle 1 in a direction approximately perpendicular to the blade 3, the blade 3 swings left and right due to its weight, but this movement is caused by the swinging member 5. and is transmitted to the spring 2. Due to the elastic force of the spring 2, the blade portion 3 continues to swing left and right for a certain period of time even when the handle 1 is not mowing in the left and right directions. This swinging motion is almost the same as the motion of a sickle that was conventionally operated by hand. In this state, the grass that comes into contact with the cutting blades 3a formed on both sides of the blade portion 3 is cut. When this swinging motion of the blade part 3 is attenuated, the handle 1 is again
The above operation is repeated by moving the blade in a direction substantially perpendicular to the blade portion 3. This work can be done even in narrow spaces that cannot be cut with a mechanical lawn mower, it can be done while standing, and it can be done without constantly moving the handle. Can be done.

In this embodiment, the spring, which is an elastic body, is substantially orthogonal to the blade and swingably connects the blade to the handle, but this is not limiting.
As shown in FIG. 3, it may be set parallel to the blade portion, and the structure and material of the elastic body are not limited.

(Effects of the invention) As described above, the present invention connects the blade part to the handle through an elastic body so that it can swing freely, so that the blade part continues to swing with one movement of the handle. Since the lawn can be mowed by motion, you can mow the lawn while standing without constantly moving your arms, which has the excellent effect of reducing back pain and arm fatigue. Furthermore, there is an excellent effect in that lawn mowing work can be easily carried out even in narrow spaces where a mechanical lawn mower cannot be used.
