Abstract

PURPOSE:To prevent the pintle of a flap from wearing at an earlier time, by automatically operating the flap in association with a main rudder without specifically providing a drive source for the flap. CONSTITUTION:A pressure receiving fixture 7 extending upward from the top end of a flap 2, is provided with a horizontally overhaging section 7A which extends exceeding the center axis XX of a pintle 9A toward a position below a solid pin 4. The upper half section of the overhanging section 7A is clamped between a pair of links 5a', 5b' constituting a flap drive mechanism. The length lof the overhanging section 7A is made twice times as large as the distance (a) between the front edge 7F of the pressure receiving fixture 7 and the center axis XX of the pintle 9A. The pair of links 5a', 5b' is formed in an L-like shape, and the solid pin 4 and a rotary block 6 are positioned at a lever higher than that of the overhanging section 7A of the pressure receiving fixture 7. Since the flap 2 are driven through the links 5a', 5b', the pressure exerted to the pintle may be made equal to the pressure of the sea water, thereby the pintle may be prevented from wearing.

Description

[Detailed description of the invention]

The present invention relates to a rudder, and more particularly to a rudder having a flap rotatably mounted on the tail end. θkui
We developed a rudder with flaps equipped with a small movement mechanism that automatically operates the flaps in conjunction with the main rudder IC without having to install a rudder. , jσ) The invention relates to an improvement of the above-mentioned 1911 IJ head. The deer described in 191 above is extremely effective in that it reduces the number of safety components to a minimum and greatly reduces manufacturing costs by simplifying the structure of each safety component.117

[By the way, I looked at the history of the VCi, and found that the bolts that connect the flaps to the main rudder were surprisingly worn out.The flap bolts were 7 [2] One of the reasons why it wears out during the season is that it wears out during the 11th season.

(The present invention C) aims to fix the flaps to the main rudder Vc without causing any wear and tear on the flaps. ((Special ICffi <iJI source without installing one flap that automatically operates IC in conjunction with the upper rudder)
The goal is to obtain the best possible rudder. According to the present invention, the main rudder is rotatably attached to the hull via the rudder shaft, the main rudder is rotatably attached to the main rudder 1+li'-α, the tail end 1 is attached to the hull, and the flap is attached to the ship's stern direction. ] / The device is slidably engaged with a passive metal fitting that protrudes from the - end of the flap toward -. 11F1

The rudder is characterized by having an overhang extending approximately equidistantly from 111 to f.

The flange 21b of the vertical pin 4 is bolted. As shown in Figures 1 and 2a, the vertical pin 4 is provided with a flange 22 at a predetermined distance from the upper end, and a lower part 11 of the flange 22 is provided.
It is equipped with a finishing surface of a predetermined height. As shown in Figure 2b, the rotating block 6 is made of a rectangular hexahedron with a rectangular or square horizontal cross section, and has two cylindrical cavities along the vertical center line, with a bush 23 on the inner surface of the hollow tij+.
