Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a normal neutral position of an operating lever, suitable for use in a remote control device for a marine engine or a similar device.

A conventional device of this type includes a lever which is pivotally attached to a casing by a shaft and has an operating rod provided with a protruding locking means at the tip, which is assembled so as to be slidable and biased in one direction; There was one in which a lock plate having one concave portion and concentric with the shaft was fixed to the casing.

Because of this structure, it was either impossible to change the neutral locking position of the lever, or it was troublesome, such as removing the lock plate from the single-phase casing, changing the position of its recess, and fixing it to the casing again. The neutral lock position could only be changed after some work was required.

A first object of the present invention is to provide a locking device that allows the locking position of a lever to be changed very easily.

A second object of the present invention is to provide a locking device that provides less resistance to the rotational operation of the lever after the lock is released and provides a good rotational feel.

A third object of the present invention is to provide a lever locking device that is easy to manufacture.

An embodiment of the present invention will be described with reference to the drawings.
In FIG. 2, 1 is a casing, 2 is a lever for operation, and 3 is a lever 2 that is pivotally connected to the casing, and a driven member 4, which is shown in the form of a disk in this embodiment, is fixed to the other end. It is the axis.

A recess 5 is provided in the grip portion 2a of the lever 2, and an actuator 7a of an actuating rod 7, which is biased in the direction A by a spring 6, is inserted into the recess.

Reference numeral 8 denotes a guide means, for example, in the form of a concave groove, provided on the lever 2, along which the operating rod can slide in the A or B direction.

Said casing 1 is integrally provided with a substantially circular locking member 10 concentric with the shaft 3, said locking member being provided with a plurality of locking means 11, concave in this embodiment, said locking member 10 A lock position selection means 12 made of a synthetic resin with good lubricity, such as Teflon or nylon, is provided on the outer periphery of the lock position so as to be in close contact with the lock position selection means 12 in this embodiment.

The lock position selection means 12 includes a plurality of lock means 1.
One lock position selection part 12a that can be fitted into one of the lock means is provided, and the outer peripheral surface of the other part of the lock position selection part is a circular sliding surface 12b centered on the shaft 3. has been done.

In this embodiment, a convex locking means 9 is provided at the tip of the operating rod 7 on the shaft 3 side, and the locking means is configured to fit into the locking position selection portion 12a of the locking means 11. There is.

Reference numeral 15 denotes a shaft (including a flexible shaft) whose one end is pivotally attached to the outer peripheral position of the driven member 4 with a metal fitting 16, and the other end (not shown) of the shaft is connected to, for example, a throttle mechanism of a marine engine. It is operated by rotating the lever 2 in the C or D direction.

The shaft 3 and the base 2b of the lever 2 are engaged with each other by, for example, serrations so as not to slip, and are prevented from being pulled out by a screw 14.

To explain the operation and effect of the present invention, the grip part 2 of the lever 2
When a is attempted to be rotated in the C or D direction as shown in FIG.
Since the lever 2 is engaged with the lever 2, the lever 2 does not rotate, so that the lever 2 is completely locked, for example, in the neutral position.

Locking the lever 2 in the neutral position like this is extremely necessary because when operating a clutch mechanism of a marine engine using another lever (not shown), for example, the throttle opening is required to be at a minimum opening. It is.

Next, when the actuator 7a in the recess 5 of the lever 2 is actuated in the direction B against the repulsive force of the spring 6 and the locked means 9 is released from the lock position selection part 12a, the lever 2 is freely moved to C. Alternatively, it can be rotated in the D direction.

Once the locking means 9 is located on the sliding surface 12b, the locking means 9 can be moved to the sliding surface of the locking position selecting means 12 with good lubricity even without operating the actuator 7a in the B direction. 12b, and the other locking means 11 into which the locking position selection part 12a is not fitted is covered by the circular part having the sliding surface 12b of the locking position selection means 12, so that the locked means 9 slides on the sliding surface 12b with little resistance (and with a good feeling), so the lever 20 rotation operation is light and has a good feeling.

Furthermore, when changing the lock position of the lever 2 with respect to the casing, remove the screw 14, remove the base 2b of the lever 2 from the shaft 3, and remove the lock position selection means 1 from the lock member 10.
2, and fit the lock position selection part 12a into the other locking means 11 at an appropriate position, and then remove the base 2a.
By fixing the lock to the shaft 3 with the screw 14, the lock position can be changed very easily, which has an excellent effect.

In addition, in the present invention, the locking member 10 is attached to the casing 1.
For example, when die-casting, the locking means 9 can be formed at the same time as the sliding surface 12b even if the outer circular portion of the locking member 10 has a rough surface. Since it is light and can slide with good feeling, it also has the effect of greatly reducing the manufacturing effort.

Although not shown, the tip end shape of the locking means 9 of the operating rod 7 is, for example, a concave shape, and the shape of the locking means 11 and the locking position selecting section 12a of the locking member 10 is, for example, a convex shape. Of course, the lock position selection means 12 may be made of a material other than synthetic resin.
