Description of the Related Art As shown in FIGS. 4 to 5, a conventional vessel rudder has an inner surface of one rudder plate 21 which is half-cut from the central portion of the rudder in the plane of the traveling direction of the vessel and molded in a predetermined shape in advance. At a predetermined position, the vertical rudder 23 and the other side of the horizontal rudder 24 having the attachment piece 22 welded to one side in a T shape over the entire length are welded to form the skeleton of the rudder main body 25 in a lattice shape. After that, it is formed in a predetermined shape so as to cover the skeleton in advance, and slot holes 26 are vertically and horizontally formed at predetermined intervals at positions corresponding to the vertical rudder bone 23 and the horizontal rudder bone 24, and the inside of the slot hole 26 is formed. The remaining rudder blade 27 is fixed to the vertical rudder 23 and the horizontal rudder 24 by welding the peripheral end portion and the outer surface of the attachment piece 22, and the rudder front end portions of both rudder blades 21 and 27 are fixed.
The rudder main body 25 was configured by welding 28 and the rudder rear end portion 29, respectively, and covering the upper and lower surfaces with the top plate 30 and the bottom plate 31.

要するばかりでなく舵本体25の重量が大きいなどの問題
点があった。Problems to be Solved by the Invention As described above, the rudder main body 25 has the preformed rudder plate 21.
The vertical rudder 23 and one side of the horizontal rudder 24 are welded and fixed to the inner surface of the vertical rudder 23 and the horizontal rudder 24 on the other side, and the mounting piece 22 attached to the other side and the remaining rudder plate 27 are provided with slot holes. Since the inner peripheral end of 26 is constructed by welding, a large number of slot holes 26 must be formed in the remaining rudder blade 27, which requires a lot of working time and the weight of the rudder body 25 is large. There were problems such as.
そこで本発明は多数の垂直舵骨23を廃して複数本の円筒
体を立設して用いることにより、これらの課題を解決す
ることを目的とするものである。Therefore, an object of the present invention is to solve these problems by eliminating a large number of vertical rudder bones 23 and standingly using a plurality of cylindrical bodies.
課題を解決するための手段 上記課題を解決するために、本発明は、少なくとも舵の
前部位とその後方部位に円筒体を立設し、この少数の円
筒体を頂板と底板で挟着し、各円筒体間及び円筒体と後
縁部との両側面を全周にわたって舵板で被覆した構成で
あり、船舶用舵の大型化にともない舵板に強度を必要と
するときは頂板と平行な位置に水平舵骨を設けるように
したものである。Means for Solving the Problems In order to solve the above problems, the present invention, at least a front portion of the rudder and a rear portion thereof are provided with a cylindrical body, and a small number of the cylindrical bodies are sandwiched between a top plate and a bottom plate, Both sides of each cylinder and both sides of the cylinder and the trailing edge are covered with rudder plates over the entire circumference, and when the rudder plate needs strength due to the increase in size of the ship rudder, it is parallel to the top plate. The horizontal rudder bone is provided at the position.
作用 従って舵本体の骨格となる垂直舵骨を廃して円筒体を用
いたこと、水平舵骨を不要、もしくは最少限にするので
構造は簡単となり、重量は軽減し、残りの舵板に対する
スロット穴の穿設が不要となるので作業時間を短くする
ことができる。Therefore, the vertical rudder bone that serves as the skeleton of the rudder body is eliminated and a cylindrical body is used, and the horizontal rudder bone is unnecessary or minimized, so the structure is simple, the weight is reduced, and the slot hole for the remaining rudder plate is used. Since it is not necessary to pierce, the working time can be shortened.
実施例 以下に本発明の実施例を第１図乃至第３図にもとづいて
説明する。１は舵本体で、２，３は垂直舵骨に代る立設
した円筒体（中空，中実の選択は自由である）で、頂板
４と底板５で挟着されている。６は前部円筒体２と後部
円筒体３の両側面を結ぶ前部舵板であり、７は後部円筒
体３と後縁部８の両側面を結ぶ後部舵板にして９は水平
舵骨であり、10は舵頭材、11は底部ピントルである。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 is a rudder main body, and 2 and 3 are standing cylindrical bodies (hollow or solid can be freely selected) instead of a vertical rudder bone, which are sandwiched between a top plate 4 and a bottom plate 5. 6 is a front rudder plate that connects both side surfaces of the front cylinder body 2 and the rear cylinder body 3, 7 is a rear rudder plate that connects both side surfaces of the rear cylinder body 3 and the rear edge portion 9, and 9 is a horizontal rudder bone. Where 10 is the rudder stock and 11 is the bottom pintle.
なお、必要に応じて第３図に示すように全周１枚または
両側２枚の舵板12で前部円筒体２および後部円筒体３を
被覆するか、または前部円筒体２の１部を残して後部円
筒体３を被覆状に後縁部８までを１枚の舵板12で被覆す
ることにより舵本体１を構成することも可能である。If necessary, as shown in FIG. 3, the front cylinder 2 and the rear cylinder 3 may be covered with one or two rudder blades 12 on the entire circumference, or one part of the front cylinder 2 may be covered. It is also possible to configure the rudder main body 1 by covering the rear cylindrical body 3 to cover the rear edge portion 8 with one rudder blade 12 while leaving the above.
発明の効果 本発明は以上のような構造であるから多数の垂直舵骨に
要した材料と水平舵骨に要した材料が不要となり、溶接
作業が直線部のみで容易となるうえに、一方の舵板に穿
設したスロット穴の加工が不要となるために作業時間が
大巾に節減されるなど卓越した効果を奏するものであ
る。EFFECTS OF THE INVENTION Since the present invention has the above-described structure, the materials required for a large number of vertical rudder bones and the materials required for horizontal rudder bones are not required, and the welding work is facilitated only by the straight portion, and Since it is not necessary to process the slot holes formed in the rudder blade, the working time is greatly reduced, which is an excellent effect.
