Description

[Detailed description of the invention] [Technical field] The present invention relates to an outboard motor mounting device.

[Background Art] A mounting device that can support an outboard motor while being fixed to the ship is sometimes used on a ship. This mounting device makes it possible to securely mount an outboard motor on a boat that does not have an outboard motor mounting section, and also allows the propulsion unit to be easily mounted during tilt-up by mounting the outboard motor away from the main body of the boat. This makes it possible to prevent intrusion into the ship and make effective use of the space inside the ship.

On the other hand, it is desired that an outboard motor be able to provide a variety of cruising postures to a vessel and improve its cruising performance by adjusting the attitude in which it is attached to the vessel.

However, Japanese Unexamined Patent Publication No. 16291/1983 discloses a fixing member that can be fixed to a ship, a support member that can support an outboard motor, and one end of each of a first link and a second link on the fixing member. By connecting the other ends of the first link and the second link to the support member with pins, a quadrilateral link mechanism is formed by the four members: the fixed member, the support member, the first link, and the second link. An outboard motor mounting device that is capable of supporting an outboard motor while being fixed to a boat, one end of which is pin-coupled to a fixing member, and the other end of which is pin-coupled to a second link. It has been proposed to include a lift cylinder device that is extendable and retractable. According to this, the outboard motor can be moved up and down by the expansion and contraction operation of the lift cylinder device.

[Problems to be Solved by the Invention] However, in the prior art, the lengths of the four members, the fixing member, the supporting member, the first link, and the second link, are unchanged, and the length of the quadrilateral link mechanism formed by these four members is The length of each side does not change even when the lift cylinder device expands and contracts. Therefore, there is a limit to how far the outboard motor can be tilted relative to the boat, and there is a limit to how many different sailing postures the boat can take.

SUMMARY OF THE INVENTION An object of the present invention is to provide a boat with various sailing postures with an outboard motor attached to the boat.

[Means for Solving the Problems] The present invention provides a fixing member that can be fixed to a ship, a support member that can support an outboard motor, and one end of each of a first link and a second link on the fixing member. By connecting the other ends of the first link and the second link to the support member with pins, a quadrilateral link mechanism is formed by the four members: the fixed member, the support member, the first link, and the second link. In the outboard motor mounting device, the first link or the second link is formed by an extendable and retractable tilt cylinder device, and the outboard motor can be supported while being fixed to a vessel. , one end is pin-coupled to the fixed member, and
The other end is pin-coupled to either the first link, the second link, the support member, the pin joint part between the first link and the support member, or the pin joint part between the second link and the support member, and the quadrilateral link The mechanism is equipped with an extendable lift cylinder device arranged so as not to coincide with each other on the sides constituting the mechanism, so that hydraulic oil can be supplied to each of the tilt cylinder device and the lift cylinder device by a hydraulic pump. This is what I did.

[Action] According to the present invention, there are the following effects.

The lift cylinder device has one end pin-coupled to the fixed member, and includes a first link, a second link, a support member, a pin-coupled portion between the first link and the support member, or a pin-coupled portion between the second link and the support member. The other end was connected to either end with a pin. Therefore, when the lift cylinder device is stationary, the fixing member, the supporting member, the first link, and the second link are separated.
The shape of the quadrilateral link mechanism formed by a person can be fixed, and the outboard motor can be moved up and down by changing the shape of the quadrilateral link mechanism by operating the lift cylinder device. Here, when the above-mentioned quadrilateral link mechanism forms a parallelogram link mechanism, the outboard motor moves up and down only in the vertical direction, and when it forms a non-parallelogram link mechanism, the outboard motor tilts. Move up and down while doing so.

Therefore, for example, by adjusting the setting position of the outboard motor relative to the boat, a part of the propeller can be positioned above the water surface, reducing the propulsion resistance of the outboard motor itself, and achieving high-speed cruising suitable for the boat. It is possible to obtain the state. Furthermore, it is possible to raise the set position of the outboard motor body relative to the vessel without changing the tilted attitude of the outboard motor body, thereby allowing the vessel to operate in shallow water.

The first link or the second link is configured by a tilt cylinder device. Therefore,
By operating the tilt cylinder device, the length of the first link or the second link of the quadrilateral link mechanism formed by the fixing member, the supporting member, the first link, and the second link is changed to operate the outboard motor. Can be tilted widely.

Therefore, for example, during accelerated sailing before the ship enters a planing state, the propeller shaft of the outboard motor body can be raised forward (trim-in), making it possible to obtain an appropriate accelerated sailing state for the ship. .
Furthermore, when the boat is running planing, the propeller shaft of the outboard motor main body can be brought forward (trimmed out), thereby making it possible to obtain an appropriate planing running state for the boat.

Further, by forming the first link or the second link with a tilt cylinder device, the link length of the quadrilateral link mechanism changes. This results in
By expanding or contracting the lift cylinder device, the tilt angle can be changed at the same time, and the manner in which the tilt angle changes can be varied and adjusted in accordance with the length of the link formed by the tilt cylinder device. Therefore, even if only the lift cylinder device is operated, by changing the length of the link formed by the tilt cylinder device in advance using the tilt cylinder device, it is possible to greatly lift up the propulsion unit and at the same time change the tilt angle. It is also possible to change and adjust the way the tilt angle changes in a variety of ways. Therefore, appropriate acceleration characteristics can be obtained as required.

To make it possible to effectively utilize the space inside a ship by preventing the entry of passengers into the ship.

The mounting device 10 is attached to the ship 1 by the expansion and contraction movement of the lift cylinder device 17 driven by the pump 35A.

5A and the tilt cylinder device 16 form a parallelogram link, the outboard motor 12 moves up and down only in the vertical direction; , the outboard motor 12 moves up and down while tilting.
