Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reverse lock mechanism that is interlocked with a switchable automatic tilt mechanism of an outboard motor.

Generally, outboard motors are equipped with a norihaas lock mechanism to prevent the outboard motor from tilting up due to the reverse propulsion force when going in reverse.When tilting up, the reverse lock mechanism must be released before the outboard The outboard motor is tilt-locked by manual operation while tilting up the outboard motor, or by constantly operating a spring in the tilt-lock direction so that the outboard motor is automatically tilt-locked when the outboard motor is tilted up.

The outboard motor's reverse lock mechanism was operated separately from the tilt mechanism.

The present invention enables switching between automatic tilt and automatic tilt release by operating a tilt stopper, and in conjunction with this switching between automatic tilt and automatic tilt release, reverse lock is released when switching to automatic tilt. The feature is that the tilt-up operation can be performed only by operating the tilt stopper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description will be given below according to embodiments illustrated in the accompanying drawings.

In Fig. 1, 1 is a bracket supported by the hull 2,
A bracket stand 4 is supported between two brackets via a bracket bolt 3 so as to be vertically rotatable.

A tilt stopper 6 having a fulcrum 5 and rotatably supported on the bracket base 4 is a tilt stopper 6, and an operation lever 7 is fixed to the tilt stopper 6 and rotates integrally therewith.

Also, the bracket stand 4 is tilted down (Fig. 1)
Then, any position between the angle θ at which the tilt stopper 6 can rotate between the bracket 1 and the bracket base 4, and the fulcrum 5 on the line (x-x) passing through the fulcrum 5 of the tilt stopper 6.
A spring 9 is installed between two points, a position 8 set on the opposite side of the tilt stopper 6, and an arbitrary position 6a in the middle of the tilt stopper 6, and when the tilt stopper is on the line xx, the spring 9 The relationship is such that the maximum load is applied to

The bracket 1 has grooves 1a, 1 for receiving the tilt stopper.
b, . . . are provided so that when the tilt stopper 6 is engaged, the outboard motor is held tilted (tilt stock).

Further, a thrust rod 10 is attached to penetrate through the bracket 1, so that the thrust receiving portion 4a of the bracket base comes into contact with the thrust rod 10 when tilted down.

The structure described above is a switchable automatic tilt mechanism for an outboard motor.

That is, the tilt stopper 6 is switched by the switching operation of the operating lever 7, and if the tilt stopper 6 is on the bracket 1 side, it automatically becomes tilt-lockable by engaging with the receiving grooves 1a+1b...

If the tilt stopper 6 is on the bracket base 4 side, the tilt will not be locked.

In the present invention, by operating the operating lever 7, the reverse lock can be automatically set and released at the same time.

11 is a reverse lock lever, 1 for bracket stand 4
2 as a fulcrum, and its tip forms a pawl 11a that functions to reverse lock when engaged with the thrust rod 10.

The spring 13 is installed so that the reverse lock lever 11 is always engaged with the thrust strand 10.

Numeral 14 is a lock lever stopper which prevents the reverse lock lever 11 from being rotated too much by the spring 13 in the tilted up state.

Further, the tilt stopper 6 has a radius R centered on the fulcrum 5.
When the cam 6b having the shape of is fixed or integrated, and the tilt stopper 6 is moved toward the bracket 1 side, the cam 6b
b, the reverse lock lever 11 is rotated about the fulcrum 12, and the claw portion 11a of the reverse lock lever 11 is detached from the thrust strand 10, and the convex portion 11b formed on the reverse lock lever 11 is moved as shown in FIG. Make money and compose.

With this structure, when the tilt stopper 6 is moved to the bracket 1 side and switched to automatic tilt, the reverse lock is released by the interlocking of the cam 6b of the tilt stopper 6 and the protrusion 11b of the reverse lock lever 11 (Fig. 2). The up operation is possible with only one operation of the operating lever 7.

When the tilt stopper 6 is moved to the bracket base 4 side to release the automatic tilt, the reverse lock lever 11 is separated from the cam 6b as shown in FIG.

FIG. 3 shows the tilted up state.

The tilt stopper 6 engages with the groove 1a or 1b to lock the tilt.

Reverse lock lever 11 is lock lever stopper 1
4, the lock lever upper surface convex portion 1lb can be pushed down by the cam 6b without excessive rotation.

As mentioned above, the reverse lock can be released by switching the operating lever 7 only when the reverse lock lever 11 is to be automatically tilted, and an operating mechanism for releasing the reverse lock mechanism is not required. A simple feature can be added to the features of the switchable automatic tilt mechanism.

Claims (1)

[Scope of Claims] 1. A bracket base supporting the outboard main body is supported by a bracket supported on the hull so as to be vertically movable, and a tilt stopper rotatably supported by the bracket base is engaged with the tilt stopper. It has a mechanism that maintains the tilt of the outboard motor by having a groove in the bra to stop the outboard motor from tilting, and an operation lever to change the position of the tilt stopper, and a bracket to adjust the tilt stopper depending on the position of the tilt stopper. A reverse lock lever rotatably attached to the bracket base in an outboard motor having a spring attached to selectively bias either the side or the opposite bracket base side, and the reverse lock lever. It has a claw provided at the tip for engaging the thrust strand and reverse locking it, a spring biasing the reverse lock lever in the direction of engaging the thrust strand, and a cam provided on the tilt stopper. and is characterized in that, when the tilt stopper is on the bracket side, the cam comes into contact with the reverse lock lever and pushes down the reverse lock lever so that the claw of the reverse lock lever and the thrust rod are disengaged. Outboard motor reverse lock mechanism.
