ABSTRACT:
A swimming aid is worn on the hand and secured to and between the forefinger and the thumb of a swimmer. The swimming aid includes a fan-shaped body portion having a relatively wide frontal edge and two lateral edges tapering rearwardly toward an apex adjacent a webbed crotch portion of the hand formed between the forefinger and the thumb. The swimming aid has a crotch receiving portion formed towards the apex of the body portion for receiving and sealingly communicating with the webbed crotch portion of the hand. Also included is a thumb receiving portion and a forefinger receiving portion, both extending laterally from the lateral edges of the body portion respectively, intermediate the wide frontal edge and the apex. The thumb and forefinger receiving portions are integrally formed with the body portion and encircle and retain the thumb and the forefinger. The body portion is formed from material sufficiently rigid to resist displacement of the thumb towards the forefinger along a plane defined by the body portion when the thumb and forefinger are retained by the thumb and forefinger receiving portions, respectively. However, the body portion is sufficiently flexible to allow retention of the opposable nature of the thumb causing the body portion to bend away from a plane defined by the thumb and the forefinger such that the thumb and forefinger can grasp objects therebetween when the thumb and forefinger are retained by the thumb and forefinger receiving portions.
