Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a counterbalancing rudder used in a small boat.

Conventionally, when attaching this type of rudder to a ship, due to the presence of a hole for side insertion formed in the rudder mounting seat plate and the presence of a ridged part at the front of the rudder plate, It was not possible to insert it into the hole, and the only way to attach it was to insert the gunwale from the bottom of the ship into the hole.

In order to overcome this drawback, it is necessary to form a notch of a size corresponding to the front protrusion 17 of the small steering plate of the steering f.1 seat plate, but this alone is not enough. When the rudder is attached to the seat plate and the vehicle is operated, the rudder shakes and the vehicle cannot be operated satisfactorily.

The present invention attaches an outer cylinder to the seat plate and uses an inner cylinder to allow the rudder to be mounted from either above or below the ship, and to prevent the rudder from shaking during operation. This is what I did.

Next, embodiments of a conventionally known rudder mounting device and a rudder mounting device according to the present invention will be described with reference to all the accompanying drawings.

FIG. 1 shows a conventionally known rudder mounting device, in which 1 is a rudder mounting seat plate fixed to the hull, 2 is a side plate, 3 is a rudder plate,
4 is a front overhanging portion, and 5 is a cylinder fixed to the seat plate, into which the gunwale 2 is inserted.

Regarding this device, as mentioned earlier, even if you try to insert the rudder into the seat plate 1 from above the ship, it will not be possible due to the front overhang of the rudder plate, and it can only be attached from below the ship. .

Therefore, there is a drawback that the rudder cannot be installed or removed at sea unless the water is quite deep.

In addition, the distance between the tube 5 and the side 2 is normally configured so that there is only a distance of about 0.3 to 1 + + + yn to prevent looseness while operating the ship, During long-term use of the rudder, for some reason the gunwale and the barrel interfered and the gunwale could not be removed from the barrel, in which case the seat plate had to be removed from the hull and repaired.

Next, the device according to the present invention is the second one. Illustrated third.

In the figure, 6 is the rudder mounting seat plate fixed to the hull, γ
is an outer cylinder fixed to this seat plate, with a flange 8 formed at its upper end, and a vertical notch 29 wide enough to allow the rudder plate to pass freely through one side of the cylinder. There is.

Reference numeral 9 denotes an inner cylinder, and a flange 10 is also formed at the upper end of the inner cylinder.

There is a rudder plate 12 at the lower end of the side 11, and an overhang part 13 is formed in the front part of the rudder plate 12.

Holes 14 and 15 are formed in the seat plate 6 and the flange 8 of the outer cylinder, and holes 14 and 15 are formed to allow the inner cylinder 9 to be inserted therethrough. The depth of cut is 16.1γ, which is enough to pass through with force.

18 and 19 are formed respectively.

The inner diameter of the interior 9 is such that the side 11 is inserted through the rudder so that the rudder does not rattle when the rudder is in use.

Bolt holes 20 to 2γ are respectively formed in the flanges 8 and 10 so as to match when the two flanges are superimposed, and 28 is a stopper that is detachably attached to the ship's side.

Since the structure is similar to that on the ground, if the steering seat plate 6 with the outer cylinder γ fixed is fixed to the hull and the inner cylinder 9 is removed and peeled off, the rudder can be accessed from either above or below the ship. It can pass through the hole provided in the flange of the outer cylinder.

Therefore, if the rudder is inserted through the seat plate and the outer cylinder from either the upper or lower direction of the ship, the gunwale 11 and the inner cylinder 9 will be in a fitted state, and the inner cylinder 9 will be inserted into the outer cylinder. 20 and 24, 21 and 25 of each company.
．． 22, 26, 23, and 2T respectively, insert the bolts into each company, and use nuts to removably fix the inner cylinder to the outer cylinder.

A stopper 28 is attached to the side near the top of the flange 10 to prevent the rudder from falling downward.

When attaching a button or rudder from below the ship, the inner cylinder may be attached to the outer cylinder in a single position.

Next, when removing the rudder, first remove it below the ship.
It is sufficient to remove the stopper 28 and the inner cylinder 9, so it is sufficient to simply pull the rudder downward.

To remove the rudder upwards, the stopper 28 needs to be the one 11, so first loosen the nuts and remove each bolt to release the fixation between the inner cylinder 9 and the outer cylinder γ, and then move the inner cylinder 9 together with the gunwale 11 upwards. When pulled up, the holes are 14° and 15° and the notches are 16 and 1.
The rudder 9 and 29 are each large enough to allow each part of the rudder, namely the side, the rudder plate button and the front overhang, to pass freely through each other, so that the rudder can be easily pulled upwards.

As described above, by using the device according to the present invention, the rudder can be easily attached and removed from either the top or bottom of the ship. The holes and notches are large enough for the rudder to pass through easily, making it very easy to install and remove the rudder.

Furthermore, while the rudder is in use, the side of the rudder is inserted into the inner cylinder to the extent that it does not rattle, so the rudder can be used safely and reliably.

Furthermore, even if the inner cylinder and the gunwale come into close contact for some reason, the rudder and inner cylinder can be removed without regard to the outer cylinder or seat plate, making maintenance and repair easy. .
