DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle structure of a management machine.

[0002]

2. Description of the Related Art A handle of a management machine is projected rearward from a handle base, and a rear end of the handle is of a horn type having a C-shape in plan view and a loop type having a rear end connected thereto. They were selected and attached according to the user's preference and work.

[0003]

However, in the prior art, once the management device for the horn-type handle is purchased, for example, the loop-type handle becomes more convenient for the work (or vice versa). , It is necessary to purchase a new handle, and to replace the entire handle, it is necessary to replace the clutch lever and the accelerator lever, etc., which is very troublesome work, and depending on the model, the gearshift lever etc. is assembled to the handle There were some management machines that could not be replaced. Therefore, there has been a demand for a handle that can be easily changed between a horn type and a loop type according to preference and work.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, in the handle which projects obliquely upward from the handle base of the management machine, the handle is composed of a handle frame having a C-shape in plan view and a rearrangement handle in a U-shape in plan view, and the handle frame is fixed to the handle base, A rearrangement handle can be attached to the rear end of the handle frame in a horn type or a loop type.

[0005]

Next, the operation will be described. When the rearrangement handle 6 constituting the handle portion A of the management machine is used in a horn type, the handle frames 4.4 are arranged so that the grip portions 6c of the rearrangement handle 6 face diagonally downward and rearward.
The connecting portion 6 of the rearrangement handle 6 is provided inside the front end portions 4b
b, 6b are adjacent to each other, and pin holes 4a, 4a,.
Are made to coincide with each other, the connecting pins 16, 16 are inserted, and the through holes 16a, 1 of the connecting pins 16, 16,.
When the snap pins 17 are inserted into the handle frames 6a, the reassembly handle 6 can be mounted on the handle frames 4 in a horn type.

When the rearrangement handle 6 is used in a loop type, the handle frames 4 are arranged so that the grip portions 6c of the rearrangement handle 6 face diagonally downward and forward.
The connecting portion 6 of the rearrangement handle 6 is provided inside the front end portions 4b
b, 6b are adjacent to each other, and pin holes 4a, 4a,.
Are made to coincide with each other, the connecting pins 16, 16 are inserted, and the through holes 16a, 1 of the connecting pins 16, 16,.
When the snap pins 17 are inserted into the handle frames 6a, the replacement handle 6 can be mounted on the handle frames 4 in a loop type.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an overall side view of the management machine of the present invention,
FIG. 2 is a plan view of the same, FIG. 3 is a perspective view showing a state in which the rearrangement handle is mounted on the handle frame in a horn type, FIG. 4 is a perspective view showing a state in which the rearrangement handle is mounted on the handle frame in a loop type, and FIG. FIG. 6 is a perspective view of the handle frame, FIG. 6 is a perspective view of the rearrangement handle, FIG. 7 is a perspective view showing a method of connecting the rearrangement handle and the handle frame, and FIG.

1 and 2, the overall configuration of the management device will be described. The engine E is mounted on the engine frame 1, the engine frame 1 protrudes forward from the transmission case 2, and an axle 7 is suspended at the lower end of the transmission case 2. A hitch 11 is provided at the center rear portion of the transmission case 2, a rotary tilling device R is mounted on the hitch 11, and a tilling claw shaft 14 is provided at the lower end of the chain case 12 of the rotary tilling device R. Are mounted on the tilling claw shaft 14, and power is transmitted to the chain case 12 from the PTO shaft protruding from the side of the transmission case 2 so that the tilling claw shaft 14 can be rotated. And

A transmission lever 3 is provided on the transmission case 2, and a handle portion A of the present invention is projected obliquely rearward from the handle base portion 15. The handle frame 4 constituting the handle portion A Is the accelerator lever 5
However, the reassignment handle 6 is provided with a side clutch lever 8.

Referring to FIGS. 5 and 6, the structure of the handle portion of the management machine according to the present invention will be described. As described above, the handle portion A of the management machine according to the present invention has a handle frame 4 which is fixed on both sides of the handle base 15 and has a C-shape in plan view, and a U-shape in plan view mounted on the rear portion of the handle frame 4. As shown in FIG. 5, the rear end portions 4b of the handle frames 4, 4 have connecting pins 16
A plurality of pin holes 4a, 4a,... For inserting 16 are inserted, and an auxiliary frame 4c for reinforcement is laid between the handle frames 4, 4. As shown in FIG. 6, the rearrangement handle 6 has curved portions 6d, 6d and grip portions 6c, 6c at the open end, and a connecting portion 6b therebetween.
A plurality of pin holes 6a are penetrated through 6b, and the connecting pins 16 can be inserted into the pin holes 6a.

A method of attaching the handle of the management machine of the present invention will be described with reference to FIGS. First,
When the rearrangement handle 6 is used as a horn type as shown in FIG. 3, the connecting portions 6b are connected to the handle frames 4.4 so that the grip portions 6c of the rearrangement handle 6 face rearward.
., The rear end portions 4b, 4b of the handle frame 4, the pin holes 4a, 4a,.
