Description

Fin structure

This creation is about a fin board structure, especially one with sufficient strength, which can reduce the overall weight and produce good propulsion effect.

Whether it is carrying an oxygen cylinder for deep diving or snorkeling leisurely on the sea surface, wearing fins can effectively increase the thrust in the water or on the water surface. Regardless of whether it is the "feet-style fins" that are to be worn directly on the feet or the "adjustable fins" that must be worn overshoes and then the fins, frogs made of rubber, PU, or other composite plastics Shoes, the impact on kicking efficiency is not too big, as long as the material is strong enough and not too soft, they still have good propulsion.

Therefore, the multi-layer fiber layer structure commonly used at present can indeed make the fin board have sufficient material strength, and will not affect the propulsion due to being too soft when swinging. However, the above-mentioned fin board structure is mainly formed by stacking a plurality of fiber layers of the same size and shape, then bonding them with resin, and then hardening through heating and pressurization procedures. After forming, the entire fin board surface has the same Strength and Flexibility. In actual use, if this structure increases the number of stacked fiber layers, it will be able to generate greater propulsion under the condition that the bending softness is allowed, but the overall weight will increase, and more kicking is required On the contrary, it cannot achieve the effect of saving effort and generating greater propulsion.
