Description

[Detailed explanation of the invention] This invention is similar to the main engine remote control device of a ship.
Used when it is necessary to release the stop mechanism installed at the normal operating limit position of an operating device with a rotary operating bundle in an emergency to operate the operating bundle beyond the normal operating range. The present invention relates to an easily releasable operating bundle stop mechanism.

For example, Utility Application No. 52-094343 (Special Publication No. 56-
In devices that remotely control the main engine from two or more different locations, such as the main engine remote control device proposed in No. 023704), if one control system fails, the other control system is used to operate the main engine. In some cases, it becomes necessary to release the stop mechanism of the operating bundle and operate the bundle outside the normal operating range.

Such an operation bundle is disclosed in the above-mentioned Utility Model Application No. 52-09434.
3 (Japanese Patent Publication No. 56-023704), this is necessary not only when using one operation bundle but also when two or more operated devices are switched and used by a switching mechanism.

In such cases, conventionally, a control bundle without a stop mechanism has been used to avoid operational inconvenience, or even if there is a stop mechanism, it is removable and cumbersome to operate. This also necessitates the use of multiple operating devices.

This idea solves this problem by providing the operating bundle with a small shaft perpendicular to its axis, and when the tip of this small shaft hits the stopper fixed to the main body of the operating device, the operating bundle stops. To release the stop, pull the small shaft toward you, rotate it, and hold the small shaft slightly pulled out so that the small shaft does not touch the stop metal fitting to release the stop mechanism. The object of the present invention is to provide a stop mechanism for an operation bundle which has a simple structure and is easy to operate.

Hereinafter, the stop mechanism of this invention will be explained based on examples.

FIG. 1 is a front view of the operating device, and FIG. 2 is a sectional view taken along line XX'.

In FIGS. 1 and 2, A is the operating handle, B is the main body of the operating device, and C is the stop mechanism.

The operating device shown in the figure is used for remote control of the main engine of a ship. For example, when it is used to switch the main engine forward or backward, the operating handle A is in the neutral position as shown in the figure, and in this position it is in the main engine. The engine is not connected to the propulsion shaft, and when the operating handle A is rotated to the
When rotated to position 2, the propulsion shaft is coupled to the main engine to propel the ship astern.

The operating handle A is connected to a shaft 2 by a key 1, and the rotation of the shaft 2 operates a stop to electrically switch the main engine forward or backward, or the rotational movement of the shaft 2 can be controlled linearly by a pinion, rack, etc. This is converted into motion, and the main engine's operating lever is pulled or pushed using a push-pull wire to mechanically switch the main engine's forward or backward movement.

Now, to operate this controller, first use the operation handle A.
When the tip 3' of the shaft 3 built into the operating handle A is pushed down against the force of the spring 4 using the thumb or the like, the pin 5 driven into the shaft 3 will be pushed down into the operating handle A. The pin 5 which was engaged with the lock fRx of the lock plate 6 and locked by the operating handle input button is disengaged from the button locking groove X and is unlocked, so that the operating handle A can be rotated freely.

Therefore, when switching the main engine of a ship forward or backward, push the tip 3' of the shaft 3 of the operating handle A.
When the main engine is rotated to the Xl position, the main engine is switched to the forward direction.

When the hand is released from the operating handle A at the position X, the shaft 3 is lifted by the spring 4, the pin 5 is fitted into the lock groove X1 corresponding to the position X, and the handle A is locked.

When the main engine is switched to the reverse side by rotating the operating handle A to the X2 position, the operation is exactly the same; in this case, the pin 5 fits into the locking groove and the operating handle A is locked.

As explained above, the normal operation range of this operating device is between Xl and X2.

Next, regarding the stop mechanism of this invention, this type of operating device is generally placed at both limit positions of the normal operating range (in the example shown, xl and A stop mechanism of the operation handle is provided at the position x2).

In the stop mechanism of this invention, when the operating handle A is at the xl position, the shaft tip 7' of the knob shaft 7 of the stop mechanism C hits the stopper 8 attached to the main body B side of the operating device, causing the operating handle to move A. Similarly, at the X2 position, it hits the stop fitting 9 and stops.

Therefore, in the illustrated state it acts as a stopper for the normal operating range.

Next, in order to release this stop mechanism and rotate the operating handle A beyond the range of 10, and the shaft tip 7' comes out of contact with the stopper 8 or 9.

(The shaft tip 7' of the knob shaft 7 and the tip of the stopper 8 or 9 will pass each other at an appropriate distance without touching each other.)

) In this state, if you rotate the knob shaft 7 a little, the knob shaft 7
The pin 12 driven in rests on the end surface 11' of the body 11 of the stop mechanism C, and the knob shaft 7 is held in a tensioned state, that is, in a stop release state.

In this way, the pin 12 and the end surface of the body 11 serve as a holding mechanism for the knob shaft 7.

The retainer 14 is attached to the knob shaft 7 and the spring 1
0, and the retainer 15 is for holding the retainer 14.

To return the stop mechanism C to the stopper state, press the knob 7.
'' is rotated in the opposite direction, the pin 12 falls into the groove 1V of the body 11 by the force of the spring 10, and the knob shaft 7 returns to the state shown.

FIG. 3 is a sectional view taken along the line z-z' in FIG. 2.

Note that yl and y2 are lock grooves at the Y1 position and Y2 position, respectively.

In addition, the ring-shaped metal fitting 13 in the drawing is attached to the main body B side of the operating device, and this is used when this operating device is used, for example, for controlling the rotation speed of the main engine of a ship.
It is provided for locking in any position.

When locking the operating handle A at a desired position, rotating the gripping metal fitting 14 of the operating handle A pushes the shaft 3 downward, and its tip 3'' engages the side surface 13 of the annular fitting 13.
', and the contact pressure locks the operating handle A at an arbitrary position.

Of course, in this case, lock groove Xll x2? 3'19
y2 is irrelevant.

As explained in the above embodiments, the releasable noodle stop mechanism of this invention is attached to the surface of the operating bundle and can be easily operated by simply pulling the knob shaft towards you and slightly rotating it. The stop mechanism of the operating bundle can be released by pressing the button, and when returning the stop mechanism to its original position, it is as simple as rotating the knob shaft in the opposite direction. When the rotational force acting on the operating bundle is stopped by the end of the knob shaft of the stop mechanism and the stopper, there is an advantage that the stress acting on these locking members is relatively small.

Easy to operate and easy to release structure)
This has the effect of providing a stop mechanism for the handle.
