Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a chair that makes it possible to perform tasks such as manual weed removal and transplant cultivation in farms and golf courses while sitting down. It is something.

[Prior Art] Conventionally, when performing such work, the current situation is that it is performed in a very stiff posture, similar to the posture of mWi in Kendo, which is bent forward.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

As the above-mentioned positions are extremely difficult and cannot be endured easily for long periods of time, workers are shunned by employers for this type of work, which is currently the main cause of the worsening labor shortage. be.

The present invention has been devised in view of the problems of the prior art, and its purpose is to provide a solution to these problems.

[Means for Solving the Problems] In order to achieve the above object, one aspect of the present invention is as follows.

That is, the thing of the present application has left and right side walls 2A, a front gate formwork 2B that is erected and connected to the tips of the left and right side walls, and a front gate-shaped handle that is erected and connected to the rear ends of the left and right side walls 2A. A frame 2 consisting of a guide frame 2C, a saddle stand 3 stretched vertically between the left and right side walls 2A of the frame 2 so as to be vertically adjustable, and a seat on the upper surface of the saddle stand, with respect to the saddle stand. A saddle 4 rotatably disposed in a horizontal direction and a wheel portion 5 disposed on the outside of the left and right side walls 2A form left and right front guide wheels 5A,
The U-turn lever section 6, which is composed of left and right rear guide wheels 5B and left and right crawler tracks 5C suspended from these, and is located outside the left and right side walls 2A, has a tip that can be raised and lowered by a pin 6A. The left and right levers 6B are connected to the left and right side walls 2A, the lower tension rollers 6D are rotatably attached to the left and right levers 6B to push down the crawler track 5C, and the left and right levers 6B are connected to the left and right levers 6B. This farm work chair is constructed of an upper tension roller 6E that is rotatably attached to the upper tension roller 6E and pushes up the crawler track 5C.

In this case, move the upper tension roller 6E to the left and right levers 6
It can be freely adjusted up and down relative to B, and can be mounted rotatably.

[Effect] The action will be explained along with the effect.

[Embodiments of the invention] Examples will be described with reference to the drawings.

1 is a farm work chair of the present invention.

Reference numeral 2 denotes a frame, which includes left and right side walls 2A arranged at a predetermined interval, and cylindrical guides 2 that are erected and connected at the tips of the left and right side walls.
B1, a front gate formwork 2B consisting of a horizontal rod 2B2 suspended from the upper end of this cylindrical guide 2Bl, and a vibrator that is erected and connected to the rear ends of the left and right side walls 2A and bent downward into a U-shape. It is composed of a gate-shaped handle guide frame 2C.

Reference numeral 3 denotes a saddle stand that is stretched between the left and right side walls 2A of the frame 2 so as to be vertically adjustable. The short vertical pipe 3A1 is loosely fitted.

The fastener screwed onto this short vertical tube is composed of a bolt 3A2.

Reference numeral 4 denotes a saddle that is rotatably arranged in the horizontal direction on the upper surface of the saddle stand by means of a connecting shaft 4A installed in the center of the saddle stand.

Reference numeral 5 denotes wheel parts disposed on the outside of the left and right side walls 2A, which include left and right front guide wheels 5A, left and right rear guide shafts 5B,
It is composed of left and right crawler tracks 5C suspended from these.

5A1.5B1 is a rotating shaft.

That is, the wheel portion 5 has a caterpillar structure in order to apply less pressure to the ground.

Reference numeral 6 denotes a U-turn lever section provided to be located outside the left and right side walls 2A, and the left and right levers 6B are connected to the left and right side walls 2A with a pin 6A at their tips, and the rear ends of the left and right levers 6B. A front gate-type handle 6C configured in a downward U-shape connecting the two, a lower tension roller 6D that presses down the crawler track 5C by being rotatably attached to the left and right levers 6B, and the left and right levers 6B. It consists of an upper tension roller 6E which can be adjusted up and down and can be freely rotated once to push up the crawler belt 5C.

That is, the upper tension roller 6E is attached to the lever 6B in a structure such that the upper tension roller 6E is rotatably attached to the tip of an arm 6B1 that is attached to the approximate center of the lever 6B so that it can be adjusted upwardly and downwardly. There is.

In this case, it is preferable that the arm 6Bl is raised and lowered along several adjustment holes (paths shown) provided in the lever 6B and fixed with bolts.

In addition, when the lower tension roller 6D is to act downward, the front gate-shaped handle 6C is pushed downward and rearward as shown in FIG.

Further, when the upper tension roller 6E is to act upwardly, the front gate-shaped handle 6C is placed in a vertically erect state as shown in FIG.

In the figure, A indicates the ground and B indicates the high ridged ground.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

When working on the surface of flat ground, or vertically along the enemy shape,
The waist height can be adjusted horizontally or depending on the height of the high ridges, and the body orientation can be freely adjusted.

That is, in the case of a chair that is normally rotatable, there is a high possibility that the spiral or central support of the chair may cause trouble to crops, ridges, etc. on the underside of the chair.

However, in the present invention, since the saddle stand 3 is attached to the cylindrical guide 2B1 and the handle guide frame 2c so as to be adjustable up and down in the vertical direction, this problem can be avoided.

Furthermore, since it has a caterpillar type structure, if it is desired to move back and forth or left and right while sitting on the object of the present invention, it is possible to move while rowing with one's feet.

That is, the crawler track 5C is stretched in order to apply less pressure to the ground, and the lower tension roller 6D and the U-turn lever part 6 are pivotally mounted on this track to enable knee-turn operation. Able to move and work while seated, making knee turns as necessary, until reaching the goal, which is the end of the work.

In this way, you can maintain a very comfortable posture while also easily enduring long hours of work.
