Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating lever device, and in short, a series of operating levers is divided into two parts, a base part and a tip part, and these parts are connected via a bent part. When the tip is moved in one direction, the electric switch in the bending part can be operated, and when the tip is moved in a direction perpendicular to the moving operation direction, another type of operation can be performed at the base. There are two systems that attempt to perform two systems of operation.

This invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 denotes an operation lever, with a base side 1a and a tip side lb.
The base side 1a is connected to a clutch device or a transmission device, and further to the operating system of a hydraulic device, and the tip side is provided with an operating grip portion 2.

3 is a bent part, and in the illustrated example, a box 4 is fixed to the upper end of the base side 1a, a long hole 5 is provided protruding from the top surface of the box 4, and the tip side lb is inserted through the long hole 5. The plate 6 is inserted through the pin 7 and fixed to the distal end side of the plate 6 through a pin 7.

Reference numeral 8 denotes a spring that presses the plate 6 onto the bottom surface of the box body 4, and is provided so that the tip end side lb of the operating lever 1 is always held in the middle of the elongated hole in the free state.

Reference numerals 9 and 10 denote electric switches installed in the box body 4, and each of the actuators 19 and 20 is provided in a suspended position divided into right and left sides with respect to the direction of the elongated hole 5 of the box body 4, When operating the tip end side lb of the operating lever 1 by pushing or pulling it toward the elongated hole, one of the actuators 19 or 20 senses the tilting of the plate 6 and turns on the electric switch 9 or 10. The electric switches 9 and 10 are connected to a solenoid that controls an operating device (clutch device, transmission device, direction control device, etc.) that is different from the operating connection device on the base side 1a of the operating lever 1. An electrical circuit is included.

Reference numeral 11 is a rubber bellows that seals the inside of the box body 4.

Reference numeral 12 denotes a support frame on which the operating lever 1 is rotatably mounted on a horizontal shaft 13J, and the left and right side plates of this support frame 12 serve as guides, and the outer side of the support frame 12 is arranged in parallel in the direction of the elongated hole 5 of the box body 4. Wall surface
The structure is such that the two parts are slidably guided.

In addition, as shown in FIG. 5, the base i side 1a of the operating lever 1
and the tip end side lb may be bent, and the box 4 described above may be interposed in this portion.

According to the configuration of the above example, when the grip portion 2 on the tip end side 1b of the operating lever 1 is grasped and the lever is operated in the direction of arrow A or opposite arrow A, the direction of the elongated hole 5 through which the lever is inserted is perpendicular. Since the operating direction is such that the operating lever 1 is rotated through the box body 4 without being bent, it is not possible to operate a clutch device, a transmission device, a switching valve of a hydraulic device, etc. connected to the base side 1a. Become.

Next, while continuing this operating state or in a state where the operation is stopped, if the tip side 1b of the operating lever 1 is operated in a direction perpendicular to the operating direction A of the operating lever, for example, in the direction of the arrow, The tip end side 1b is bent by the elongated hole 5 of the box body 4, and the plate 6 deforms the spring 8 as shown in FIG. 0N.

Conversely, when the switch is operated in the opposite direction of the arrow, the switch 9 is turned ON in the same manner as described above. In this manner, by turning on the switch 9 or 10, the operating mechanism section of the system other than the above can be operated via the electric circuit.

As described above, the present invention divides a series of operation levers into a base and a tip, which are connected via a bent part, and when the tip is operated in one direction, an electric switch of the bent part is activated. The structure is such that it can be operated, and based on the operation of the tip in a direction perpendicular to the direction, another type of operation is possible at the base. It has the unique effect of allowing different systems of operation to be performed at different locations.

In particular, as described in the description of the embodiments, the present invention has two
Since operations of different systems can be performed at two locations, it is extremely effective because one operation can be continued while the other is being operated at the same time. Incidentally, it is possible to provide a regulating groove 15 for guiding and regulating the tip end side 1b of the operating lever 1, and the direction of this regulating groove 15 is aligned with the elongated hole 5 of the box body.
If the lateral groove 14 is provided at a predetermined location in a direction perpendicular to the direction of the regulating groove 15, the switches 9 and 10 can be set to zero only in the lateral groove 14.
It can be N or 0FF.

Further, the regulating groove 15 may be provided in a crank shape or a hook shape.
