ルを装着する方法が採用されている。A. Problems to be Solved by Conventional Techniques and Inventions Conventionally, in a cruiser-class or dinghy-class yacht, a keel (aggregate) is assembled and glass wool is piled up on the outside thereof, or a plywood is bent and mounted. In this method, a hull is first prepared by pouring a resin liquid containing glass wool into a mold, and then a keel is mounted inside the hull.

ことがあった。However, in the hull structure of a yacht made by the conventional method, since the hull is composed of a curved surface plate, if the hull is made thin to reduce its weight, for example, in the case of stormy weather, strong impact force with the sea surface is repeated There was a problem that the bow part was twisted and deformed by receiving. For hulls made of plywood etc., the hull's restoring force is suppressed by water pressure in the water, but if it is left on land for a long time, the hull deforms due to its own restoring force and returns to its original shape. It was sometimes gone. When placed on land, the hull sometimes deformed due to the weight of the hull and could not return to its original shape.

Means for Solving the Problem The present invention relates to a hull, and an arc-shaped first line segment element whose apex M corresponds to the bottom of the hull, and the apex M of the first line segment element to the first line segment element. Second segment corresponding to a bow arranged on a plane S ′ passing through a perpendicular line m drawn to a straight line connecting both ends of the segment element and being orthogonal to the plane including the first segment element. At least a bow portion is constituted by a structure composed of an element and a large number of linear element groups extending in a straight line from the first line segment element toward the second line segment element, The portions at both ends of the apex M and the second line segment element are subdivided into a large number until the surface formed by the linear element group becomes a curved surface or almost a curved surface. It is characterized by being connected by an element group.

造体Bを構成し、この構造体Bにより少なくとも船首部
分を構成している。FIG. 1 is a diagram schematically showing a structure B used in the present invention, and the present invention will be described with reference to FIG. In the drawings, the thickness of each member is omitted for convenience of explanation.
In the present invention, the frame member 4 which is the arc-shaped first line segment element,
From the apex (middle point) M of the first frame member 4 to both ends 4a, 4b
A frame material corresponding to, for example, a bow which is a second linear segment element disposed on a plane S ′ passing through a perpendicular m drawn down to a straight line connecting the two and orthogonal to a plane including the first frame material 4 5
And a linear base material 6 which is a large number of linear elements linearly extending from the first frame member 4 to the second frame member 5, and constitutes a structure B, and at least the bow portion is formed by the structure B. Is composed.
ここで第1の枠材4の右半分について(第1図におい
てMから上半分について)n等分し、第1図中上からの
等分点(円弧の端部からの等分点)を順番にP1、P2…Pn
とする。また第2の枠材5についてもn等分し、その等
分点をQ1、Q2、…Qnとし、P1とQ1同士、P2とQ2同士…Pn
とQn同士を各々基材6で結合する。Here, the right half of the first frame member 4 (from M to the upper half in FIG. 1) is divided into n equal parts, and an equidistant point from above (an equidistant point from the end of the arc) in FIG. In order P1, P2 ... Pn
And In addition, the second frame member 5 is also divided into n equal parts, and the equally divided points are set to Q1, Q2, ... Qn, P1 and Q1 between P2 and Q2 between Pn.
And Qn are bonded to each other by the base material 6.
さらに第1の枠材4の左半分について(第1図におい
てMから下半分について)もn等分し、同様にそれら等
分点と前記Q1、Q2…Qnとをそれぞれ基材6で結合する。
この場合nの数が大きければ双曲放物面と呼ばれる曲面
が形成される。ただし実際には、基材6としては丸棒材
料等横幅のある材料が用いられるので完全な双曲放物面

1、第2の枠材を細分化し、その細分化された領域を直
線要素で結ぶことが必要である。Further, the left half of the first frame member 4 (from M to the lower half in FIG. 1) is equally divided into n, and the equally divided points and the Q1, Q2, ... .
In this case, if the number n is large, a curved surface called a hyperbolic paraboloid is formed. However, in reality, since a material having a horizontal width such as a round bar material is used as the base material 6, a perfect hyperbolic parabolic surface is not obtained, but if a base material 6 having a small horizontal width is used and the number thereof is increased, it is possible to obtain a double shape. A curved surface similar to a paraboloid is formed.
Conversely, in the present invention, it is necessary to subdivide the first and second frame members to the extent that a hyperbolic paraboloid is formed and to connect the subdivided regions with linear elements.

In this embodiment, two hulls B shown in FIG. 1 are used, and they are joined in the longitudinal direction, that is, the first frame members 4, 4 are joined to form a hull. In the figure 40
Is a first frame member, which also serves as the frame members 4 and 4 in FIG. The first frame member 40 is formed by bending a band-shaped plate member into an arc shape. In addition, the second frame members 50, 50 located respectively in front of and behind the first frame member 40 are made of linear prismatic members, and between the first frame member 40 and the second frame members 50, 50. A large number of round rod-shaped base materials 60 are arranged in parallel with each other. As a material of the frame members 40 and 50 and the base material 60, for example, glass fiber is used. Regarding the coupling structure of the frame members 40, 50, 50 and the base material 60, for example, a large number of grooves are formed in the frame members 40, 50, 50, and each end of the base material 60 is fitted into these grooves. Adhesive hardening is adopted.

It is desirable to equally divide the second material 50 into n parts in the length direction, and to connect the corresponding equal points to each other by the base material 60, so that a large strength can be obtained. In addition, standardization of each material can be facilitated. When the structure is manufactured in this manner, glass wool impregnated with an adhesive is applied to the outer surface side of the structure, and thus, for example, a hull of a yacht is formed.

Strength can be obtained. Therefore, the bow portion does not deform even when repeatedly subjected to a large impact force from the sea surface, and does not deform due to its own weight even when placed on land. Further, in the past, since the curved surface material was used as described above, when the material was placed on land, the material sometimes deformed due to the restoring force of the material itself due to the loss of water pressure.
In the present invention, such a thing is also solved, and the deformation of the bow portion is fatal to the hull, so the practical effect of the present invention is very large. Moreover, since the thickness of the material can be small, the weight and cost can be reduced. Further, since water flows along the straight line of the bow portion, the resistance of water is small, and in addition to being lightweight, a large boat speed can be obtained.
