Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improved safety structure for motors, boats, and bows. More specifically, in the racetrack of Japanese Patent Application No. 131806 (Japanese Patent Application Publication No. 278180) previously proposed by the applicant. It relates to the improvement of the safety structure of motors, boats and bows.
[0002]
[Prior art]
At the racetrack, six race boats sail on the race water surface as many times as necessary while drawing an ellipse, and race at a maximum speed of about 80 to 83 km / h in a straight section. .
[0003]
Therefore, in addition to the pulling waves that these race boats sail and make waves, the waves generated by natural conditions such as winds collide with the quay and other equipment in the racetrack, and return waves that bounce off each other. This may hinder race boats from running and may cause each race boat to capsize.
[0004]
And when a race boat turns a corner, it tries to take the inner course as much as possible while competing with other boats, so contact between the race boats is unavoidable, and the tip of the bow collides with the other race boat players. In some cases, the race boat is killed or injured, or the race boat that is off the course collides with equipment on the racetrack and the player himself is injured.
[0005]
Therefore, the applicant provided a soft bow attachment at the tip of the motor / boat deck, and integrated a soft bow of approximately an isosceles triangle with a bow block and a soft bow inner. Provided the safety structure of the motor, boat and bow provided.
[0006]
[Problems to be solved by the invention]
However, the safety structure of the motor / boat / bow is such that the soft bow / inner, top fender and bottom fender have right-angled tips. There is sex.
[0007]
Also, since there is a step at the end of the bow block that is covered and fitted to the soft bow, it may cause injury if it contacts a player.
[0008]
And since the soft bow has a sealed structure, the water accumulated in the soft bow will cause the soft bow to corrode, so the boat will be lifted upside down and drained upside down after the day's race. There is a need.
[0009]
Further, as shown in FIGS. 17 to 19, in the safety structure of the motor / boat / bow, the inner chain ic, keel k, center liner are attached to the bow block before the bottom plate middle plate is attached to the bottom of the ship. The through grooves 14b ₄ , 14b ₃ , and 14c ₃ for attaching cl are formed, and the bow block may absorb water and expand and crack.
[0010]
In addition, since the tip of the soft bow block inner was not extended to the gunnel, the adhesion between the bow block and the gunnel was insufficient, and when the race boat collided with another boat, an impact was applied. It will cause damage.
[0011]
Further, since the adhesion between the middle of the bottom plate and the front of the left and right plates is only a small gap, the adhesion is insufficient and, as described above, causes damage.
[0012]
