Description
- 1. Field of the Invention
- The present invention is relates to an improved buoyancy aid for floating legs and lower torso of a swimmer as during the development of arm stroking techniques, strength and endurance, especially to a buoyancy aid which has adjustable buoyancy and an improved contacting surface for reliable and convenient use.
- 2. Description of Related Art
- Swimming is a popular exercise and excellent method for body figuration and health maintenance. However, to get the most effective result or body benefit after swimming, especially for a competitive swimmer, efficient swimming posture should be learned by swimmers first. Except for the help of a good trainer, various different forms of swimming practice aides and other devices are usually useful to assist swimmers with swimming learning. In particular, these aids or devices are also beneficial to swimmers practicing different ways of swimming, including the butterfly, backstroke, breaststroke and freestyle swimming stroke. One kind of the aids or devices is in regard to flotation devices which are employed to effect or supplement flotation and provide total or partial immobilization of a portion or portions of a swimmer's body in order to concentrate on the development of techniques involving other body portions involved in a total stroke makeup. Examples of devices of this nature are buoyancy aids for legs and kickboards which have been developed in a variety of forms. In regard particularly to leg buoyancy aids, such devices are employed to provide flotation for the legs of a swimmer and to substantially immobilize the legs of a swimmer against movement relative to each other, while permitting the development of improved techniques or strength and endurance with respect to arm motions and/or breathing techniques.
- Leg buoyancy aids of various types have been developed primarily from inflated or foam materials which within limited size constraints produce significant buoyant assist to the legs of a swimmer. “Kick Board”, for instance, is usually formed with a rectangular shape by using foam material. U.S. Pat. Nos. 4,406,628, 4,781,638 and 5,518,429 all disclose a specialized kind of kick boards. As how a kick board is named, kick boards are usually hand-held to train the legs of swimmers. In a circumstance without enough professional equipment, kick boards can be used as a leg buoyancy aid by holding one of the kick boards between legs of a swimmer. It is understood that the rectangular shape of a kick board is hard to hold by legs. Therefore, a buoyancy aid having two enlarged portions joined by a thinner connecting portion to position the enlarged portion above and below the legs of a swimmer is helpful to be conveniently held. In some instances, composite flotation elements have been provided which effect some extent of conformance with body contours to assist in the selective retention of the leg buoyancy aid with minimal leg effort on the part of the swimmer. Rademacher U.S. Pat. No. 4,379,704 shows a similar device following the same design idea. However, while the flotation objective has been generally achieved by most of these devices, the adaptability of these devices to swimmers of different sizes and weights has been inadequate in many instances. In addition, some of these devices have not been constructed in such a fashion and surface as to be easily or steadily held by a swimmer which inevitably results in the need of struggling from the swimmer to hold these buoyancy aids.
- Accordingly, an object of the present invention is to provide a buoyancy aid which is effective in supplementing the buoyancy of legs of a swimmer for exercise or drills directed to improving breathing techniques or arm stroking techniques, strength and endurance.
- Another object of the present invention is to provide a buoyancy aid which has a universal configuration for easy retention by the legs of a swimmer irrespective of the particular size and shape of the legs of the swimmer.
- A further object of the invention is to provide a buoyancy aid which can be successfully employed by swimmers of substantially different sizes and weights, i.e., from children to adults with the least needed effort.
- A further object of the present invention is to provide a buoyancy aid having varied buoyancy in order to help swimmers of substantially different sizes and weights according to the actually need of the swimmers, and the desired buoyancy of the buoyancy aid is almost fixed or unchanged in water after the buoyancy of the buoyancy aid is decided because the content of the buoyancy aid is flowable or movable inside the buoyancy aid to slightly adjust buoyancy of the buoyancy aid.
- In order to achieve the objects set forth, a buoyancy aid includes an integrally formed a body having an inner space formed therein. The body has a spherical portion and a stopper portion, and a connection portion formed therebetween to join them together and being shaped according to a prolate having a outer surface being continue and smooth. The inner space is formed inside of the body and a hole is formed at one end of the spherical portion to communicate the inner space with the outer circumstance.
- Especially, a plug installed on the hole is selectively pulled out to allow water or air from the outer circumstance to enter the inner space so as to adjust buoyancy of the buoyancy aid. And the poured water in the buoyancy aid is able to move toward the buoyancy aid under water to stabilize or balance buoyancy of the buoyancy aid in water and a swimmer can easily control or use it. Besides, two layers of specially treated material is mounted respectively on two opposing lateral faces of the connection portion to provide a soft and easily holding surface thereon for legs of a swimmer so as to facilitate the use of the buoyancy aid during swimming.
- Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

- FIG,7 is a schematic side view in accordance with the present invention showing the use of the buoyancy aid when a swimmer is swimming.
- Reference will now be made to the drawing figure to describe the present invention in detail.
- Referring to FIGS. 1, 2 and3, the present invention is relates to a
buoyancy aid 1 for floating legs and lower torso of a swimmer as during the development of arm stroking techniques, strength and endurance. Thebuoyancy aid 1 comprises an integrally formed,unitary body 10. Thebody 10 is shaped according to a prolate having a outer surface being continue and smooth. And thebody 10 has aspherical portion 11 and astopper portion 12 thespherical portion 11 is a substantially spherical hollow body and thestopper portion 12 is a substantially prolate hollow body, formed respectively at two opposing sides of thebody 10 to be spaced from each other and aconnection portion 13 formed therebetween to join thespherical portions 11 and thestopper portion 12 together and formed the continuously smooth outer surface of thebody 10 that is holding area. Aninner space 14 is located inside thebody 10 and extends from thespherical portion 11 to thestopper portion 12 by continuously extending in theconnection portion 13. Also, theconnection portion 13 is recessed toward center and the whole periphery of thebody 10 for providing comfortable holding thebuoyancy aid 1 between legs of a swimmer. Referring further to FIG. 5, twolayers 15 of specially treated material, which can generate considerable friction between one of thelayers 15 and any object abutting against the whole surface of thelayer 15, are respectively paved on two opposing lateral faces of theconnection portion 13. Ahole 16 is formed at one end of thespherical portion 11 and aplug 2 is used to fill thehole 16 tightly. Theplug 2 has acover portion 20 and a tube-like portion 21 integrally formed with thecover portion 20 and having awater passageway 210 formed therein.Several openings 211 are formed on the surface of the tube-like portion 21 to communicate the outside of the tube-like portion 21 with thepassageway 210. And at least twoprotrusions 22 are formed at the distal end of the tube-like portion 21 away from thecover portion 20 of theplug 2. - Therefore, as referring to FIGS. 2, 3 and4, the
plug 2 is installed and inserted into thehole 16 of thebody 10 and fill thehole 16 tightly by itscover portion 20. The outer radius of the tube-like portion 21 is almost same as the inner one of thehole 16 so thatprotrusions 22 formed on the outer surface of the tube-like portion 21 is not able to pass through thehole 16 after they are inserted into thebody 10 and located in theinner space 14. Accordingly, when theplug 2 is inserted into thebody 10, thehole 16 is tightly sealed by thecover portion 20 of theplug 2 so as to stop the communication of theinner space 14 with the outer circumstance. And when theplug 2 is pulled out by hand, most of the tube-like portion 21, including theopenings 211, is going to expose to the outer circumstance except the distal end of the tube-like portion 21 becauseprotrusions 22 of the tube-like portion 21 will abut against the inner face of thebody 10 surrounding thehole 16 to stop the movement of theplug 2. In this instance, water or air from the outer circumstance can easily enter theinner space 14 of thebody 10 by means of theopenings 211 andpassageway 210. It is understandable that the amount of water and air filled in theinner space 14 will affect buoyancy of thebuoyancy aid 1 when thebuoyancy aid 1 is placed in a swimming pool. Therefore, buoyancy of thebuoyancy aid 1 is obviously adjustable by pouring water into or out of theinner space 14 of thebody 10. And the buoyancy-adjustable function of thebuoyancy aid 1 apparently benefits swimmers of substantially different sizes and weights according to the actually need of the swimmers. Besides, due to the unitary formedbody 10 and itsinner space 14, the filled water inside thebody 10 is flowable and moveable to always stay inside any water-sunk portion of thebody 10. Therefore, buoyancy of thebuoyancy aid 1 is almost fixed or unchanged in water so as to ease the use of thebuoyancy aid 1 by a swimmer. - Referring to FIGS. 5, 6 and7, because the special material of the
layers 15 formed on sides of theconnection portion 13 is usually soft and easily generates friction thereon when something is abutting against thelayers 15, aswimmer 3 can conveniently holds the buoyancy aids betweenlegs 31 of theswimmer 3 in a labor-saving way due to considerable friction generated between skin oflegs 31 of theswimmer 3 and thelayers 15 of thebuoyancy aid 1 attached thereon. Therefore, it is no need to worry about escape of thebuoyancy aid 1 for theswimmer 3 during swimming due to the tight and steady contacting of thelayer 15 and skin of theswimmer 3. And the soft surface of thelayers 15 and the tight contacting between thelayer 15 and skin of theswimmer 3 will successfully prevent skin of theswimmer 3 from being hurt. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the method and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of ingredient, material, and arrangement of steps within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
