【考案の詳細な説明】
この考案は遊泳者が遊泳に際し、足を水中において上下
動する場合、特に上方への移動のときに推進効果をより
増大させるようにした遊泳用足ひれに係るものである。[Detailed description of the invention] This invention relates to swimming flippers that increase the propulsion effect when a swimmer moves his or her feet up and down in the water, especially when moving upwards. be.
従来多用されている遊泳用足ひれば、水中での下降時に
おいてだけ推進力の増大を図っており、上昇時での推進
力についての考慮が余り払らはれていなかったので、水
中での遊泳速度にもある程度の限界を余儀なくされてい
る一方、近年益々海洋開発についての関心が高まってい
る状態に鑑み、水中でのより迅速な活動が要望されてい
る。Conventionally, the commonly used swimming soles were designed to increase the propulsive force only when descending underwater, and little consideration was given to the propulsive force when ascending. While they are forced to limit their swimming speed to some extent, in view of the growing interest in ocean development in recent years, there is a demand for faster underwater activities.
そこでこの考案は前述のような遊泳速度のより増大を所
期し得る一方、構造簡単な遊泳用足ひれを提供しようと
するもので、足嵌め部前方の空所に連通ずる通水孔を、
足裏踏部を境にして前後に夫々穿設してなるものである
。Therefore, this invention is intended to provide a swimming flipper with a simple structure while still being able to increase the swimming speed as described above.
It is made by drilling holes in the front and back of the sole of the foot.
以上図面についてこの考案の一実施例を述べるに、ゴム
製の本体Ｂにおける足嵌め部１の前方中央に、長手方向

嵌め部１直前において空所ａｔ ａを設け、これら空所
ａ、ａと連通ずる通水孔３，４を、足裏踏部５を境にし
て前方と後方とに夫々設け、遊泳者が水中を上昇すると
き、特に後方の通水孔４からも水が矢印Ｚ方向から流入
して推進力を従来における夫れよりもさらに増大させる
ようにしである。To describe one embodiment of this invention with reference to the above drawings, a partition piece 2 is formed along the longitudinal direction at the front center of the foot fitting part 1 of the rubber body B, and the foot fitting part 1 is formed on both sides of the partition piece 2. A space at a is provided just before the part 1, and water holes 3 and 4 communicating with the spaces a and a are provided at the front and rear sides of the sole tread part 5, respectively, so that the swimmer can swim underwater. When rising, water also flows in from the rear water hole 4 in the direction of arrow Z, thereby increasing the propulsive force even more than in the conventional case.
図中６は遊泳者の足である。6 in the figure is the swimmer's foot.
この考案は前述のような構成であるから、遊泳者が足嵌

て簡単にして、安価に製作可能である。Since this device has the above-mentioned configuration, when a swimmer puts his or her feet 6 into the foot fittings 1 and swims underwater, the water moves in the direction of the arrow as seen in the left half of Figure 4 when descending underwater. It flows in the g direction, generates a propulsive force, and can gradually descend.However, when rising underwater, as shown in the right half of Figure 4, the water flows in the arrow y direction. , the water flows in the direction of the arrow 2 through the water passage hole 4, which generates a propulsive force that is significantly greater than the conventional propulsive force when ascending underwater. In addition to being able to levitate more quickly and easily, the overall structure is extremely simple and can be manufactured at low cost.
