Description

[Detailed Description of the Invention] The present invention relates to a stopper structure for an operating lever of a traveling machine or the like.

That is, in the operating lever of a traveling machine, etc., which is configured so that the operating lever, which is pivoted on a support shaft in the operating case, can be rotated along a long groove on the case surface.
The operating lever can be rotated to properly lock it in a predetermined position to prevent it from coming off naturally, and it also has a simple structure that allows for smooth operation with a positive feel while providing the feeling that the lever is being operated. The purpose of the present invention is to provide the following information so that it can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a plan view of the handle part of the tiller, in which a loop-shaped handle 6 is attached to a handle frame 5.
Both ends of the handlebar frame 5 are fixed, a main gear shift lever 7 is extended behind the handlebar frame 5, a main clutch lever 8 is installed on the right side of the handlebar 6, and a throttle lever 9 is installed on the right side of the handlebar 6. Configure.

An operation case A is installed inside the right side of the handle 6, and the operation case A is constructed by joining a right case a1 and a left case a2.
1 is fixed to the right side of the handle 6 via a support 10, and the upper surface part 11 of the right case a1 and the left case a2
The front and rear parts of the upper surface part 12 are overlapped and fixed by bolts and nuts 13, 13', and a long groove 2 in the front and rear direction is formed at an interval between the inner sides of both the upper surface parts 11, 12 in the middle. The upper surface of the upper surface portion 12 along the line 2 is configured to display neutral N at the center, high speed H at the front, and low speed L at the rear.

Also, the end of the support shaft 1 is fixed to the side surface 14 of the right case a1, and the other end is fixed to the side surface 14 of the left case a2.
The boss part b of the operating lever B, which is inserted into the long groove 2, is fitted into the support shaft 1, and both protrusions 17, 1 are fitted into the boss part b.
The protrusions 17 and 17' are provided so that they can be respectively joined to both operating rods 18 and 18' which form a fulcrum 7' and can be rotated around a fulcrum O, and are connected to an arm 21 on a rotation fulcrum 20 of the gate-shaped handle 19. Both interlocking rods 2
2, 22' with one end of the Bowden wires 23, 23', respectively, and both Bowden wires 23, 2
The outer end at 3' is attached to the operating rod 18,1
8', and both Bowden wires 23, 23' are interlocked and connected to the main unit so that the sub-shift can be controlled in height.

C is a plate-shaped stopper made of resin, a hole 25 is bored in the center of the flat side part 24, the lower end of the side part 24 is bent at a right angle to form a lower part 26, and the upper end of the side part 24 is bent at a right angle. is bent sideways to form a bent part 27, and along the tip edge of the bent part 27, there is a concave edge 3 in the center which becomes a flat concave part, and on both sides of the concave edge part 3, which becomes a flat inclined part. 4 and 4' are connected to each other, and the end of the support shaft 1 is fitted into the hole 25, and the side surface 24 and bottom surface 26 of the stopper C are formed.
and the bent portion 27 on the side surface 1 of the left case a2.
5. Attach the lower surface part 28 and the upper surface part 12 so that they do not move inwardly as shown in FIG. The mounting configuration is such that it protrudes a little from the plane.

When the operating lever B is rotated around the spindle 1 and moved to the A position as shown in Figures 8 and 9, the sub-shift becomes neutral, and is rotated to the B position to match the low speed L. Then, the protrusion 17' presses and operates the operating rod 18', and the Bowden wire 23' performs a low-speed sub-shift operation, and when it rotates to the C position and adjusts to the high speed H, the protrusion 17 presses and operates the operating rod 18. In this way, the Bowden wire 23 allows a high-speed sub-shift operation to be performed.

In that case, when operating lever B is rotated, the rod of operating lever B will come into contact with and slide against concave edge 3 and inclined edges 4 and 4', giving a feeling of operation. In addition, at the predetermined position of the operation, the rod of the operating lever B engages with the concave edge 3 and the inclined edges 4, 4' to prevent it from coming off naturally. Ru.

In this way, the present invention provides support for the support shaft 1 in the operation case A.
In the operation lever of a traveling machine, etc., which is configured so that the operation lever B, which is pivoted at , the upper end of the plate-shaped stopper C is bent laterally to form a bent part 27, and a concave edge 3 is formed along the tip edge of the bent part.
and sloped edges 4, 4' continuous to both sides thereof,
These concave edge portions 3 and inclined edges 4, 4' are configured to protrude slightly into the long groove 2 along one side of the long groove 2, and are positioned so as to come into contact with the operating lever B. By engaging the operating lever B with the concave edge 3 and the inclined edges 4, 4' of the stopper C, it is possible to prevent the operating lever B from coming off naturally, and when rotating the operating lever B, simply push and pull the operating lever. Since it comes into contact with and slides on the resin surface of the stopper C with a chisel,
The stopper C can be easily molded from resin, and the operation case A can be easily operated while giving a feeling of operation.
It can be easily installed by inserting it into the machine, and since the operating lever only comes into sliding contact with the resin stopper during operation, there is no wear and tear, and there is no abnormal noise during operation, making it suitable for use. It has the characteristics that can be implemented.
