Description

[Detailed Description of the Invention] This invention relates to a structure for attaching a wire for operating an actuating lever to an actuating lever.

Conventionally, in mechanisms that use a wire to operate the actuating lever, if the outer wire fixing part that supports the lever and wire vibrates, a stopper at the end of the wire (often crimped with lead etc. at the end of the cable) is used. ) is designed to be directly attached to a hole in the operating lever, and if there is no slack in the wire between the fixed part of the outer wire and the stopper at the end of the wire, hunting of the lever due to vibration may occur. or,
This was often accompanied by chatter vibration to the operating lever (or operating pedal) provided at the other end of the wire. Therefore, in such a structure, a slack is provided in the wire between the outer wire fixing part and the wire tip fixing part as described above, but in this case, the wire becomes curved and cannot be smoothly inserted into the outer wire. Something happened. In addition, in order to prevent the above-mentioned problems, a rotating pin with a wire hole is attached to the operating lever.
After passing the wire tip through this through hole, we estimate the desired amount of play between the wire tip and the rotating pin, and attach a stopper to the wire tip that is designed to tighten the wire with a screw, thereby creating play in the wire. Some things were hot. With this type, the screws loosen due to the vibration of the operating lever.
The stopper may not be securely fixed to the end of the wire, and the operating lever (or operating pedal)
Even when I tried to move the actuating lever by operating the button, the actuating lever sometimes did not move. in this case,
In order to prevent the screw from loosening, tighten the screw firmly against the stopper, which will cause the wire to become twisted, making it difficult to pull out the wire from the wire passage hole of the rotating pin or insert it into the wire passage hole when performing maintenance work. The problem was that it became difficult. Additionally, in the process of assembling the operating lever and wire during mass production, the tip of the wire must pass through the small hole of the rotating pin twice, and the screws must also be tightened, resulting in a problem of poor work efficiency. It was hot.

In view of the above, this invention provides play between the rotation pin attached to the actuating lever and the tip of the wire without bending or twisting the wire when attaching the wire to the actuating lever 1, and also provides a play between the rotating pin attached to the actuating lever and the tip of the wire. installation,
The object of the present invention is to provide a structure for attaching a wire to a lever, which can be removed extremely easily.

To achieve this purpose, the structure of this invention is as follows. That is, a rotary pin having a bifurcated portion formed by a slit for inserting a wire is rotatably attached to an actuating lever that is pivotally attached to a fixed part by a support shaft, and a stopper at the tip protrudes from the slit. A clip having a guide roller that holds the wire inserted into the slit in the slit is attached to the bifurcated portion of the rotating pin.

Next, this invention will be explained based on embodiments shown in the drawings.

In the figure, an operating lever 1 is used to control or adjust a certain type of operation or state, and one end thereof is attached to a part of a vehicle body 2, for example, and a support shaft 3
It is pivoted by. A return spring 4 is attached to the center of the operating lever 1 and biases the lever 1 to rotate clockwise about the support shaft 3. A lever stopper 5 is provided on a part of the body 2 to fix the operating lever 1 rotated by the return spring 4 in a predetermined position. Wire 6 is actuating lever 1
One end (not shown) is supported by an outer wire 8 supported by a fixing part 7 attached to the body 2. And wire 6
The wire 6 is attached to the end protruding from the outer wire 8.
An actuating lever or operating pedal (neither shown) is attached to operate the. Further, at the end of the wire 6 on the operating lever 1 side, there is provided a cushion 9 made of rubber or the like, and a wire stopper 10 attached to the end of the cushion 9 by caulking lead or the like as in the prior art.

A rotating pin 11 is attached to the operating lever 1 at the end opposite to the support shaft 3. This rotating pin 11
has a large diameter portion 11a shaped like a round bar, and a slit 11b for inserting the wire 6 is cut from the center of one end of the large diameter portion 11a to a predetermined depth.
Both sides of the slit 11b are bifurcated clip attachment parts 11c, 11c. The rotating pin 11 has a large diameter portion 11a followed by a large diameter portion 11a.
A small diameter portion 11d having a smaller diameter is formed concentrically. Further, the clip attachment portions 11c, 11c of the rotation pin 11 have clip attachment holes 11e,
11e are each opened.

After inserting the small diameter portion 11d of the rotating pin 11 formed as described above into the mounting hole 1a drilled at the end opposite to the support shaft 3 of the operating lever 1, the small diameter portion 11a protrudes from the mounting hole 1a. Crimp part 11d,
It can be attached to the actuation lever 1 by forming the caulked portion 11f. The end of the wire 6 on the wire stopper 10 side is attached to the slit 11b of the rotating pin 11. In this case, the wire stopper 10 is positioned on the opposite side of the fixing part 7 with respect to the operating lever 1, as shown in FIG. After inserting the wire 6 into the slit 11b of the rotating pin 11, the clip attachment hole 11
The rod portion 12a of the clip 12 is fitted into the clips 11e and 11e, and the hook portion 12b thereof is locked to one clip attachment portion 11c. At this time, a guide roller 13 is loosely fitted to the bar portion 12a of the clip 12 in the slit 11b, and the guide roller 13 positions the wire 6 within the slit 11b. When the wire 6 is attached to the rotating pin 11 in this manner, the cushion 9 and the wire stopper 10 are kept separated from the rotating pin 11 by a spring or the like (not shown) provided on the outer wire 8.

In the above configuration, by operating the operating lever (or operating pedal) on the side of the wire 6 that protrudes from the outer wire 8, the wire 6 is
When the wire 6 is moved in the direction, the wire 6 moves within the slit 11b of the rotating pin 11 while rotating the guide roller 13. After the cushion 9 of the wire 6 comes into contact with the rotating pin 11, the operating lever 1 is rotated counterclockwise about the support shaft 3 as shown by arrow B against the biasing force of the return spring 4. let As the actuation lever 1 moves in this manner, an actuation cable (not shown) or the like attached to the actuation lever 1 controls or adjusts certain operations or conditions.

On the other hand, when the operating lever (operating pedal) is not operated, the operating lever 1 is brought into contact with the lever stopper 5 by the return spring 4, and the cushion 9 and the wire stopper 10 are separated from the rotating pin 11, as described above. . The distance between the cushion 9 and the rotating pin 11 is such that even if the operating lever 1, the fixed portion 7 of the outer wire 8, the wire 6, etc. vibrate due to the vibration of the body 2, the two do not come into contact with each other. Therefore, even if the actuating lever 1 vibrates, it vibrates independently of the operating lever side, so the actuating lever 1 does not cause hunting. Furthermore, since the vibration on the operating lever side is also independent of the vibration of the operating lever 1, the operating lever does not cause chatter vibration as in the conventional case. Then, the wire 6 is attached to the operating lever 1, and the wire 6 is inserted into the slit 11b of the rotating pin 11.
the guide roller 1 against the rotating pin 11.
It is sufficient to attach the clip 12 together with the clip 3.
Further, when the wire 6 is to be removed from the operating lever 1, the clip 12 can be removed from the rotating pin 11. Therefore, it is extremely easy to attach and detach the wire 6 to and from the actuating lever 1, improving work efficiency.
Furthermore, since the wire 6 is not strongly tightened by the guide roller 13 to the slit 11b, the wire 6 will not be bent or twisted.

Therefore, according to this invention, it is possible to very easily attach and detach the wire to and from the actuating lever, and the time required for attaching and detaching the wire can be shortened and the number of man-hours can be reduced. Further, hunting of the operating lever, chatter vibration of the operating lever, etc. can be eliminated.
