Title: Surfing and windsurfing board

Description

Surfing and windsurfing board

The invention relates to surfing and windsurfing boards with a particularly pronounced flexible zone which runs from the ^central bar stabilizing the longitudinal line on both sides to the outer edges.

Ever since surfing and windsurfing boards were built, attempts have been made to achieve a more perfect adaptation to a wide range of requirements through individual design. The length, width, shape of the outer line, thickness (volume) distribution, the course of the underwater hull's lines in the longitudinal direction and the underwater hull's lines in the transverse direction have proven to be particularly important variables. These variables can be combined in any way and influence the board's handling characteristics accordingly. A flexible design of the underwater hull's lines in the longitudinal direction was also considered (see: "Surf" magazine, issue 8/1985, pages 30 and 31; publisher: Delius Klasing + Co, Siekerwall 21, 4800 Bielefeld), but this has not yet been adopted.

By using the known variables, surfing and windsurfing boards could be adapted quite well to specific requirements (speed, maneuverability, all-round properties, tipping stability, etc.), but only at the expense of other properties. The more specifically a surfing or windsurfing board was designed for a task, the more other aspects had to be neglected.

Title: Surfing and windsurfing board

The invention is based on the task described above
to significantly reduce the disadvantages mentioned above. It is intended to
to make better use of the variables known so far and to construct surfing and windsurfing boards that
despite being geared to specific requirements, have improved overall properties,

This goal is achieved by the fact that, seen in the longitudinal direction,

at least in the front area of the board a central bar ( 2 ) I

of at least 3cm width in conventional 8' thickness ■, I

while the remaining width of the board to the edge of the board

is so flexible ( 3 ) that it bends under pressure |

and then reforms when the pressure is released. Through the |

!&bull;j permanent central web ( 2 ), from which the formation on both sides |

to the outer edges of the board, the line I remains

of the underwater hull in longitudinal direction essentially stable, ⁵ J

while the lines of the underwater ship are in transverse f

direction deforms when pressure is applied and when pressure is released |

A preferred embodiment is shown in the an-?

Proverbs 2 to 4. I

In the drawing, the subject matter of the invention is shown in a

example shown. I

The surfing or windsurfing board is moved from the middle to the f

Outer edges are so flexible that the underside J

water vessel deforms in the transverse direction when pressure is applied and ^then deforms again when the pressure is released. The flexible zone ( 3 )

is produced by rejuvenating the material, whereby \

the flexible zone ( 3 J at least 20cm from the stern j-

in the longitudinal direction, but viewed from the rear not more than |

up to the height of the mast base { 1 ). If necessary, f

the resulting cavity is filled with flexible material, f

preferably filled with an elastic plastic (4) in order to regain the original shape. The shape shown and described is only an example of how the invention can be implemented.

A board construction according to the invention for surfing and windsurfing boards gives the product significantly better maneuverability and all-round properties due to the flexibility achieved in the line of the underwater hull in the transverse direction, without negatively affecting the line of the underwater hull in the longitudinal direction, which is essentially responsible for the speed.

A board construction according to the invention does not cause any

Difficulties in serial production or individual production. |

Surfing and windsurfing board characterized in that, viewed in the longitudinal direction, at least in the front area of the board, a central bar (2) of at least 3 cm width in conventional thickness remains, while the remaining width of the board up to the edge of the board is shaped so flexibly (3) that it deforms when pressure is applied and returns to its original shape when the pressure is released. 2.)
