Description

[Detailed description of the invention] This invention is a marine outdrive unit in which a release lever is attached to the end of a fixed shaft that fixes a tilt handle that tilts the outdrive unit up and down with respect to the hull of the ship. This invention relates to a tilt handle device.

Conventionally, outdrive units installed on the outboard stern of small ships transmit the output of the internal combustion engine mounted inside the ship to the propeller via a universal joint or the like from the power shaft. The rudder is integrally formed at the bottom, and when steering the hull, a tubular steering lever is rotatably attached via a spherical member to the transom plate, which is fixed to the rear of the hull with mounting bolts. The outdrive unit is connected to the hull through a steering rod whose one end is slidably fitted into the tube of the steering lever so that it can be expanded and contracted, and whose other end is rotatably connected to a member of the outdrive unit by a spherical member. On the other hand, steering is performed by tilting left and right.

In addition, when the vessel is stopped or stopped in shallow water, the release lever attached near the U-shaped tilt handle fixed to the upper rear end of the outdrive unit
After operating in the release direction, pull up the tilt handle to tilt up the outdrive unit.

Thereafter, when starting the boat, the outdrive unit is tilted down again, the tilt lock device is locked at a predetermined position, and the boat is started.

In addition, the U-shaped tilt handle can be used by inserting the end of the fixed part into the hole drilled in the lid member or case member of the outdrive unit, and then connecting the fixed end of the tilt handle with the lid member or the case member. The fixing shaft is attached to the hole that passes through the member, while the member that pivotally supports the release lever with respect to the outdrive unit is provided separately from the tilt handle and its fixing shaft. There is.

Here, since the outdrive unit is installed on the outside of a small boat, the structure should be as simple as possible, and
There is a demand for a compact and lightweight structure.
As mentioned above, the tilt handle and release lever that are used together when tilting up and down the outdrive unit are installed close to each other.
If the parts related to the tilt handle and release lever are made common, the number of parts will be reduced accordingly, and the outdrive unit will be made more compact and lightweight, thereby reducing manufacturing costs.

Therefore, the present invention was devised in response to the above-mentioned conventional demands, and aims to simplify the structure and reduce manufacturing costs by standardizing the related parts of the outdrive unit's tilt handle and release lever. The purpose is to

That is, in the present invention, the fixing portion of the tilt handle is inserted into a hole drilled in a member of the outdrive unit, and the hole passing through the member of the outdrive unit and the fixing portion of the tilt handle is inserted into the member of the outdrive unit. In an outdrive unit, a fixed shaft is provided so as to intersect with a hole drilled in the hole, and a fixed shaft is inserted through the intersecting hole, and a release lever is attached to one end of the fixed shaft.

Embodiments of the present invention will be described below with reference to the drawings.

First, in the embodiment of the present invention shown in FIG.
On the other hand, the swivel forks 4 are each pivotally supported with a pin 5 as a fulcrum, and the outdrive units 1 to 6, which are held so as to be tiltable vertically and horizontally via their shafts, are mounted within the hull transom 1. The output of the internal combustion engine (not shown) is transmitted from the power shaft 7 to a universal joint (not shown) built in the bellows-like tube 8 and a forward/reverse gear (not shown) built in the upper gear case 9.
Via the clutch shaft, drive shaft, etc.
The signal is transmitted to the propeller 10.

Further, a rudder 11 for steering is integrally formed with the outdrive unit 6, and a steering rod that slides in the tube of the steering lever 12 by operating a grip 13 of a steering lever 12 provided on the ship from side to side. Through the movement of 14, the steering operation is performed by tilting the ARA I drive unit 6 to the left and right with respect to the hull transom 1.

Furthermore, when the outdrive unit 6 is tilted up when the ship is stopped, etc., the outdrive unit 6 can be tilted up to the swivel fork 4 using the tilt handle 16 provided at the upper rear end of the rear I drive unit 6.
The outdrive unit 6 is tilted up in the direction of the arrow U using the pin 5 as a fulcrum, and when the ship is to be driven again, the outdrive unit 6 is tilted down to a predetermined position in the direction of the arrow.

Therefore, in the embodiment of the present invention, as shown in the enlarged views of FIGS. 2 and 3, both ends of the U-shaped tilt handle 16 are bored into the upper lid member 9a of the upper gear case 9 of the outdrive unit 6. The fixing shaft 18 is inserted into the hole 17, passes through the hole that passes through the upper lid member 9a and the fixing portion of the tilt handle 16, and then the one end 18a of the fixing shaft 18 is inserted through the upper lid member 9a. A release lever 20 is rotatably supported on one end 18a of the protruding member through a sleeve 19.

Here, a coil spring 21 is stretched from the transom plate 2 side to one end of the release lever 20.

The release lever 20 shown in FIG. 3 tilts down the outdrive unit 6 in the direction of the arrow, which is its normal position, and in this state locks the outdrive unit 1-6 by a conventionally known locking means.

Next, when tilting up the outdrive unit 6 in the direction of arrow U, the tilt lock device 22 provided at the bottom of the swivel fork 4 is released by operating the release lever 20 in the direction of arrow R. Therefore, tilting up is possible.

Therefore, in the tilt handle device for a marine outdrive unit of the present invention, one end of the fixed shaft of the tilt handle used during tilt-up and tilt-down operations is used as the shaft support member of the release lever. This has the effect of simplifying the structure of the outdrive unit, and also making the outdrive unit more compact and lightweight.

Furthermore, since the number of parts can be reduced, it is also effective in reducing manufacturing costs.
