Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control handle device that can be operated in two directions.

As shown in FIG. 1, a conventional remote control handle device has an operating handle 2 pivotally mounted on a substrate 1.
There is one in which a push-pull cable 3 is connected to the base 21 of the handle 23 as a remote control cable, and can be operated in two directions, clockwise and counterclockwise, from a neutral position shown by a solid line in the figure.

However, in this conventional handle device, the swinging angle of the operating handle 2 is considerably large, and the linear movement of the push-pull cable 3 is performed by connecting it with an arcuate trajectory, which causes strain, resulting in a lack of smooth operation and a serious problem. In this case, the cable becomes bent as shown by the dashed line A in FIG. 1, making it impossible to operate. This is especially noticeable in the case of two-way operation because the apex of the arc must be the neutral point and the center of the stroke cannot be placed at the apex of the arc. Increasing the radius of the arc will make the trajectory closer to a straight line, but this will increase the size of the device itself, making it impractical.

In view of the above-mentioned problems, the present invention provides a remote control handle device that has a simple structure, operates smoothly without being unnecessarily large, and operates a remote control cable in a nearly straight trajectory.

The present invention will be explained below with reference to embodiments shown in the drawings. Note that the same parts as in the conventional example are given the same numbers.

As shown in FIGS. 2 to 4, the operating handle 2 is connected to a fixed arm 24 that is integral with the handle from a base 21 of a handle 23 to which a grip 22 is attached, and that is pivotable relative to the base. It consists of an arm 25 and an arm section branched into an arm 25, and is swingably attached to the substrate 1 so as to be able to perform predetermined movements.

That is, the distal end 26 of the fixed arm 24 and the swinging arm 2
5 is the operating handle 2 shown in FIG.
The connecting pin 2 is inserted into the arc-shaped elongated holes 11, 11 formed in the substrate 1 so as to slide on an arc centered at the intermediate position between the tips 26, 27 in the neutral position of the board 1.
8 and 28, and the base 21 connects with each tip 26 and 27 at the neutral position of the operating handle 2.
It is connected and engaged with a continuous elongated hole 12 bored in the substrate 1 by an engagement pin 29 so that it can slide on a continuous locus of two circular arcs centered at . In this embodiment, the engagement pin 29 also serves as a connection means for the push-pull cable 3, and the push-pull cable 3 is connected to the base 21.
The outer cylinder is fixed to the end of the substrate 1 with a fixing member 13. The operating handle 2 is biased downward by a spring so that the tips 26 and 27 are located at the lower ends of the arcuate long holes 11 and 11. In this embodiment, a coil is attached to a pin 30 implanted in the substrate 1. Wind the spring 31,
The starting and ending ends of the coil spring 31 are engaged with the connecting pins 28, 28, respectively, and are biased.

According to the handle device according to the present invention, in the neutral position shown in FIG. 3, the coil spring 31 biases the entire operating handle 2 downward in the figure, so that the handle device maintains a stable state and constantly changes from the swinging state to the neutral state. Trying to go back. If you hold the grip 22 and swing the operating handle counterclockwise, the engagement pin 29 will move around the left tip 27 in the figure as shown in FIG. The tip of the push-pull cable 3 also follows a similar trajectory. When it swings clockwise, it similarly swings around the right tip 26. In the end, the tip of the push-pull cable 3, that is, the remote control cable, is guided through two circular arc-shaped continuous elongated holes 12, and can follow a nearly straight trajectory.

According to the present invention, the remote control handle device has a simple structure and the operation guide trajectory of the remote control cable is made close to a straight line without increasing the size unnecessarily.
It is a two-way handle device that operates more smoothly and reliably, is easy to assemble, and has great benefits.
