Abstract

PURPOSE:To prevent an outboard motor from penetrating into a hull and thereby enlarging an effective space, by making a slide member movable along upper and lower guide channels formed in left and right arm members upon kick-up of the outboard motor. CONSTITUTION:When an obstacle collides with a front lower portion of an outboard motor 2, a second reverse lock 18 is unlocked to disengage a bracket 5 from a hull 3 and thereby move the bracket 5 together with the outboard motor 2 through upper and lower rollers 11, 12 and 13, 14 along upper and lower guide channels 6, 7 and 8, 9. The upper and lower guide channels 6, 7 and 8, 9 are formed along loci of movement of the upper and lower rollers 11, 12 and 13, 14 about a center area A formed at the upper end portion of the outboard motor 2 on the hull side, that is, a front upper portion of an engine 2a. Accordingly, the outboard motor 2 is rearwardly rotated about the center area A, and is kicked up.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application in the Acid Industry The present invention relates to a support device K for vertically movably attaching an outboard motor, which is attached to a boat and generates propulsive force, to the hull of the boat.

BACKGROUND TECHNOLOGY AND PROBLEMS Generally, an outboard motor has an engine installed at its upper end, and the engine power is transmitted to the lower end to rotate a grubber installed at its lower end. The outboard motor has a downwardly slanting forward part of the engine section mounted at the stern, and the thrust of the outboard motor is transmitted to the hull through this mounting. .

By the way, as shown in Japanese Utility Model Application Publication No. 53-153696, the outboard motor can be moved up and down from the mounting part of the outboard motor. The lower blade part is tilted up to the upper position and stored.

By the way, when the above-mentioned ship is sailing, driftwood or the like may hit the lower blade of the outboard motor, and in this case, the lower blade of the outboard motor rotates to the upper blade, causing a so-called kick-up effect. It is necessary to soften the impact of the iW driftwood attack. The center of rotation of the outboard motor during this kick-up action coincides with the center of rotation during lift-up, and the outboard motor rotates around a rotation shaft provided below the engine and in the front force section. It's designed to make you feel like you're walking.

However, with such a mounting position of the rotation shaft, the upper end of the outboard motor and the upper front force of the engine portion largely enter into the interior of the hull during kick-up. Therefore, the engine entry space and the space within the hull become narrower.

Therefore, we installed an arm protruding from the stern toward the rear of the hull.
It has been proposed that an outboard motor is attached to the protruding end of this arm so that the center of rotation during kick-up is located at the rear of the boat.

However, although this support structure for an outboard motor can prevent the engine part from entering the hull during kick-up, the center of gravity of the entire boat is significantly moved to the rear of the hull. As a result, water builds up at the rear of the hull, creating a large amount of resistance and making it difficult to reach high speeds.There was also the problem that if the speed suddenly decreased, the outboard motor would get buried in the undertow. .

Therefore, the present invention prevents the upper end of the outboard motor from moving too far into the hull during kick-up, without moving the mounting position of the outboard motor to the rear of the stern, thereby freeing up the effective space inside the hull. It is an object of the present invention to provide a support device for an outboard motor which can be expanded and expanded. A pair of left and right arm members are provided to protrude toward the rear of the hull, and a pair of upper and lower guide grooves extending in the longitudinal direction of the hull are formed in the upper and lower portions of these left and right arm members, respectively. On the other hand, the outboard motor mounting bracket is connected between the left and right arm members through the upper and lower finger movers, which are slidably fitted into the upper and lower guide grooves of the left and right arm members, respectively. and the upper and lower guide grooves are arranged so that when the lower end of the outboard motor is rotated toward the rear of the hull, the upper end of the outboard motor that is attached to the bracket is the center region. Above,
In the outboard motor support device of the present invention, which is formed along the lower slider movement locus and has a more functional structure, a When the outboard motor is kicked up by a load acting on it, the outboard motor is moved by being guided by the upper and lower indexers sliding from the front of the hull toward the rear through the upper and lower guide grooves. (9 brackets) Rotate with K.

At this time, since the shapes of the upper and lower guide grooves are set in advance so that the outboard motor rotates around the upper end portion of the outboard motor on the hull side, the upper end of the outboard motor In the natural state, the outboard motor is one core of the outboard motor itself;
the lower finger mover in the opposite direction to the direction of movement during kick-up,
In other words, it will be pressed against the front of the hull in the upper and lower guide grooves. Therefore, during normal sailing, the outboard motor is positioned in front of the hull in the upper and lower guide grooves, near the stern, and the center of gravity of the entire boat is prevented from moving rearward.

example of real power Hereinafter, actual woven examples of the present invention will be explained in detail based on the drawings.

1 and 2 show an outboard motor support device 1 according to an embodiment of the present invention, through which an outboard motor 2 is attached to a hull 3.

That is, the support device 1 is arranged between left and right arm members 4 and 4 protruding from the stern 3a toward the rear of the hull, and a bracket 5 disposed between the left and right arm members 4 and 4 of the crL.
It is equipped with The left and right arm members 4, 4a are formed of rigid plates and are opposed to each other in the left and right direction of the hull n1. At the upper and lower ends of the left and right arms 111sIit4, 4a, there is a pair of arms extending in the longitudinal direction of the hull from the base end (right end in the figure) to the tip of the left and right arm members 4.4a. Upper and lower guide grooves 6, 7 and 8, 9 are formed. -Power, said book tsu) 5t! Formed into a thick plate 1
Upper and lower rollers 11.12 and 13.14 as upper and lower fingerers are mounted on both the left and right sides of the rollers in the longitudinal direction of the ship through mounting plates 10.10a. The upper, lower rollers 11, 12 and 13°'4 are provided with circumferential grooves in the shape of pulleys.
The lower rollers 11.12 and 13, 14 are rotatably fitted inside the upper and lower guide grooves 6.7 and 8, 9 of the arm member 4.4a, so that the bracket 5 It is attached to the left and right arm members 4, 4a. The outboard motor 2 is mounted on the bracket 5 via a mounting device 15. By the way, the outboard motor 2, as mentioned in the recent technical explanation,
The two engines that serve as the power source are housed in the cover A at the top end.
The power of this engine 21 is lower than f! aFI
The propeller 2b1 provided on the ship 8 is different in shape so that the propeller 2b portion is submerged underwater when it is attached to the hull 3. The mounting device 15 is arranged at the lower end portion of the engine 2&.

The mounting device 15 is, of course, provided with a steering mechanism (not shown) that rotates the outboard motor 2 along a horizontal plane when the rudder is turned. In order to prevent the outboard motor 2 from separating from the bracket 5 when going backwards, a first reverse lock 17, etc. are provided between the tilt shaft 16, which becomes a rotation axis when raising the boat, and the outboard motor 2 when going backwards. ing. Furthermore, the mounting device 15 is provided with a tilt device (not shown) for tilting up the outboard motor 2.
When tilting up, the first reverse lock 17 is automatically released by the driving force of the tilt device, and the outboard motor 2 is separated from the bracket 5 and rotates upward around the tilt shaft 16. ing.

By the way, the upper and lower guide grooves 6, 7 and 8, 9 formed in the left and right arm members 4.4a are located at the upper end of the outboard motor 2 on the hull side when the first reverse lock 17 is locked. The center area A is the top jl1 minute in front of Maji Engine 2&.
The upper and lower rollers 11.12 and 13.14 are formed along a trajectory that moves when the lower end of the outboard motor 2 is rotated toward the rear of the hull. Therefore, in this example, the guide grooves 6 and 8 of the upper blade are formed in the shape of 1Ils that slopes slightly downward from the front of the hull toward the rear, and the guide grooves 7 and 9 of the lower blade are formed at the front of the hull. The top of the buttocks towards the rear is formed into a curve. However, as the lower end of the outboard motor 2 rises during kick-up and the outboard motor 2 becomes horizontal, the bracket 5 also becomes horizontal. (
(left side in the figure) extends long toward the rear of the hull from the terminal ends of the guide grooves 6 and 8 of the upper blade. 9. At the beginning of the guide grooves 7 and 9 of the lower blade (shown on the right in the figure), a curve s'ya 9m that smoothly bends upward is formed, and at the same time, the guide groove 6 of the upper blade At the starting end portion of 8 and 8, hook-shaped bends m6m and 8a are formed.

Furthermore, between the lower end of the bracket 5 and the hull 3, there is a
The second reverse lock 18 includes a locking piece 18a, a claw #18b, a spring 18e that urges the locking piece isb to the locking piece 18m, a stopper 18d of the claw member 18b, etc. It is provided. Note that the lock between the locking piece tSa and the claw member 18b is such that when a load from the rear of the hull acts on the bracket 5, the lock will be released when the load exceeds a certain set value. The load set when the lock is released by the second reverse lock 18 is smaller than the release load of the 11th J-bar lock 17, and is set to be larger than the thrust force of the gobbler 2b when moving backward.

With the above configuration, the outboard motor of this example is supported 1! The action of I will be described below.

(I) When attaching the outboard motor 2 When the outboard motor 2 is attached to the bracket 5 of the support R1 via the attachment device 15, the first reverse lock 17 is locked to the bracket 5 and the upper part is rotated.

The shapes of the lower guide grooves 6, 7 and 8, 9 are formed so that the rollers 11, 12, 13, 14 are moved around the upper end of the front force of the engine 21 of the outboard motor 2. , the outboard motor 2 tends to have its own center of gravity, and the gIA section 2b section below it. Grass, upper and lower ends of bracket 5 - 211, 12 and 13.14
are pressed against the starting ends of the upper and lower guides @6.7 and 8.9.

At this time, the outboard motor 2 moves to the vicinity of the hull 3 together with the bracket 5, the bracket 5 comes into contact with a stopper 19 provided on the hull 3, and is stopped, and the second reverse lock 18 is locked. Furthermore, when the outboard motor 2 is in a stationary state, as the rollers 12 and 14 of the lower blades ride on the bent portions 7m and 9m formed at the beginning gs portions of the guide grooves 7 and 9 of the lower blades, The upper blade rollers 11 and 13 are connected to the hook-shaped bent portion 6a at the starting end of the upper guide grooves 6 and 8.
, it was inserted within 8 breaths. Therefore, in such a stationary state, the second reverse lock 18 is locked and the upper blade engine 2a portion of the outboard motor 2 is prevented from moving toward the rear of the boat.

(H) When the outboard motor 2 operates to rotate the propeller 2b when moving forward or backward, thrust is generated by the propeller 2b, and this thrust is transmitted from the mounting device 15 of the outboard motor 2 to the bracket 5. And from this bracket 5 above, the lower opening -211, 12 and 13.14, and the left.

The ship moves forward by transmitting the signal to the hull 3 via the right arm member 4*4at. -! Furthermore, when moving backward, thrust in the opposite direction is obtained by reversing the propeller 2b, and this thrust in the opposite direction is applied to the first reverse locks 17. The second reverse lock 18 is depressed and the hull 3 is pulled, and the vessel moves backward. Q. During this backward movement, the thrust in the opposite direction by the puller propeller 2b is used instead of the first thrust. By increasing the locking force of the second reverse locks 17 and 18, it is possible to prevent the outboard motor 2 from being unlocked and only the outboard motor 2 being rotated during reverse movement.

(To) Tilt up Next, when the ship is moored or landed, it is necessary to lift the 2t outboard motor out of the water. Tilt-up is performed. That is, when the tilt device is activated, the outboard motor 2 moves the tilt shaft 7) 16' of the mounting device 15! ! - The lower end rotates to the upper blade as the center fL
At this time, since the movement locus of the outboard motor 2 and the movement locus of the bracket 5 are different, the driving force of the tilt device unlocks the first reverse lock 17 - five-line rope n1
Only the outboard motor 2 rotates. Then, as shown by the broken line in FIG. 1, the outboard motor 2 is tilted up and the n1 propeller 2b is lifted above the water surface.

■ If an obstacle such as driftwood collides with the lower front side of the outboard motor 2 during kick-up sailing, the second reverse lock 1 will be activated due to the load caused by this collision.
When the lock 8 is released, the lock between the bracket 5 and the hull 3 is the outer shell, and the bracket 5 is connected to the outboard motor 2 as well as the upper and lower rollers 1.
1, 12 and 13. Upper and lower kite grooves 6 through 14,
7 and 8 degrees 9. At this time, above,
The lower guide grooves 6.7 and 8.9 are arranged in the upper, lower a-la II, 12, and 13.
14, the outboard motor 2 is rotated rearward around the central region M and is kicked up, mitigating the impact caused by collision with the obstacle. This allows the obstacle to escape. In FIG. 1, the movement state of the outboard motor 2 at the time of kick-up is shown step by step by two-dot chain lines, and the upper and lower rollers 11, 12, and 13 corresponding to the movement state of the outboard motor 2 at that time are shown in stages. .1
The movement position of 4 is designated by the same symbol 't' as the movement position of outboard motor 2.
It is shown by the plots marked b*c, d, .

There is no rattling in G5. Furthermore, αb>αa, βb>βa
This is the setting.

Therefore, in this actual winding example, when kicking up, the outboard motor 2 rotates around the central area A and the engine 2a (D@force upper part m). It is possible to prevent air from entering the hull 3 or to significantly reduce the amount of air entering the hull 3. Therefore, the rear part of the hull 3 can be used as an effective space during navigation, expanding the space inside the hull 3. The claws can be expanded.

In addition, in this embodiment, the tilt shirt 16 of the mounting kfii 15 is installed at the hull 3 port, so even when tilting up, the engine 2 & part of the outboard motor 2 will not enter into the hull 3. The amount of waste can be reduced as much as possible.

Figure 3 shows another example of a bracket 5, in which upper and lower shafts 20.21 are provided as sliders, and the upper and lower shafts 20 and 21 are attached to a mounting plate 10.1.
The recessed portions protruding from 0 m are slidably fitted into the upper and lower guide grooves 6, 7 and 8.9, and the upper and lower shirts) 20 and 21 are both 1) 1 [handled as a stopper. The stoppers zz, zas 22b, and 22e are fixedly installed. Even if the five brackets are configured in this way, the same function as in the actual winding example described above can be achieved.In addition, in this actual example, The bent portions 7m and 9m formed at the starting ends of the lower guide grooves 7 and 9 are bent toward the upper blade, but depending on the inclination of the bracket, the slider of the upper blade can be bent into the upper guide groove. If the lower blade can be guided into the bent portions 6m and 8a of the lower blades 6 and 8, the bent portions 7m and 9m of the lower blade may be bent horizontally or downward.

DETAILED DESCRIPTION OF THE INVENTION As described in detail below, in the outboard motor support device of the present invention, when the outboard motor is kicked up, the outboard motor slides along the upper and lower guide grooves formed in the left and right arm members. As the slider moves around, the outboard motor, which is attached to the bracket integrated with the slider, rotates around the upper end of the outboard motor on the hull side, which causes the boat to move. It is possible to prevent the external engine from entering the inside of the hull, or to greatly reduce the number of mermaids entering the hull. Definitely,
The dead space inside the hull caused by the outboard motor entering is significantly reduced, and the effective space can be expanded. In addition, during normal use, the outboard motor is placed near the stern due to its own weight and the strength of the hull of the left and right arm members, so the center of gravity of the entire boat is moved to the rear of the hull. It has various excellent effects such as being able to prevent this.
