(Cl. 9-330) This invention relates to the general field of aquatics, and is more particularly directed to a plurality of swimming aids and to a unique method of using these devices, the total result being to introduce and teach an entirely new procedure for propelling the human body through the water.

Prior art swimming devices such as fins for the feet, fins for the hands and boards of varying designs are all well-known and in popular use throughout this and other countries. The swimming aids as herein presently contemplated, all are directed to increasing the surface of contact between the swimmer and the water, and thus increase the rate of propulsion therethrough. Novel arm and hand swimming accessories in various configurations and sizes, all as hereinafter more fully set forth, furnish a greatly increased area of contact to be controlled by the arms of the swimmer than has ever before been considered possible. Further, the arms of the swimmer work together in unison to guide the novel swimming planes set forth in the drawings rather than independently and alternately as is now required with the presently known devices.

Similarly, swim flippers or fins have been designed to provide a large water contact area to be controlled by the feet of the swimmer. The fins are generally rectangular and flat in configuration, and the linear peripheral contours may be varied in accordance with the skill, strength and desires of the swimmer. Novel interlocking features have been incorporated to permit the fins to be used either singly as in present practice, or preferably as a unit with both feet working in unison to propel the swimmer through the water.

It is contemplated that by using the novel swimming planes aflixed to the arms and the flipper attached to the feet and interlocked, the swimmer will be able to operate his arms in unison and his legs in unison in a new swimming motion and method. By grasping the blade of the swimming plane and flexing it upwardly and downwardly with the hands and simultaneously coordinating the actions of the hands with upward and downward movements of the arms, a rhythmic, paddle-like motion can be set up. Upon proper manipulation of the swimming planes by the hands and the arms, a hydrodynamic current action of the water may be established that is quite similar to the action of the flippers on a fish. The leg and foot operated fins can be utilized to amplify and augment the currents and movements of the arms by coordinating the leg strokes in a manner to give the optimum propulsion through the water. It is contemplated that the leg strokes and coordination presently used by expert swimmers when swimming the butterfly type of breast-stroke will be satisfactory for the present swimming method.

It is thus seen that an apparatus and method has been devised to enable a swimmer to guide his body upwardly and downwardly through the water by utilizing extended surfaced swimming planes and fins. By alternating upward and downward movements of the arms and coordinating the directing movements of the hands and the power strokes of the legs, the swimmer may guide his progress and propel himself through the water near the surface thereof in much the same manner as a porpoise.

It is therefore an object of this invention to provide improved swimming planes and fins of the type set forth.

It is another object of this invention to provide novel swimming planes and fins of configuration permitting large surface to water contact areas.

It is another object of this invention to provide novel swimming planes and fins designed to permit porpoiselike propulsion through the water.

It is another object of this invention to provide novel arm operated planes and leg operated fins to provide uniform simultaneous movements of the arms and of the legs.

It is another object of this invention to provide novel swimming planes and fins incorporating readily disengageable sections to facilitate alternating movements of the arms and of the legs.

It is another object of this invention to provide novel swimming planes and fins including body member engaging facilities adapted for easy grasping and ready disengagement in case of emergency.

It is another object of this invention to provide novel swimming planes and fins that are rugged in construction, inexpensive in manufacture and trouble-free when in use.

Other objects and a fuller understanding of the invention will be had by referring to the following description and claims of a preferred embodiment thereof, taken in conjunction with the accompanying drawing wherein like reference characters refer to similar parts throughout the several views and in which:

Although specific terms are used in the following description for the sake of clarity these terms are intended to refer only to the particular structure of my invention selected for illustration in the drawings and are not intended to define or limit the scope of the invention.

Referring now to the drawings, I show in FIG. 1 a swimming plane or flipper 19 adapted for use with the arms of the swimmer. The flipper may be constructed of a stiff material covered with a heat sealing vinyl plastic to render it waterproof or the entire board can be constructed of a flexible material such as rubber or suitable plastic. In the embodiment illustrated, the flipper includes a front guide 12 which is pivotally connected to the arm guide 14 by the transverse hinge 16. Similarly, the arm guide 14 pivotally connects to the trailing guide 18 by the transverse hinge 20. Right and left arm sleeves 22, 23 and 24, secure the arms to the arm guide 14 and the trailing guide 13 and are arranged to permit quick and safe arm removal to prevent entrapment of the swimmer in case of emergency.

As best seen in FIGS. 9 and 10, the arm sleeves 22, 23, 24 and 25 are secured to the guides and are constructed of strong, flexible material to allow arm insertion without shearing. When desired, the free edge of the sleeve may be formed into a longitudinally rolled extension 26. This construction allows arm insertion into the sleeve by a sideways action and permits quick disengagement upon reversing the sideways movements. A medially positioned hand opening 28 is provided along the transverse hinge 16, to permit manual positioning of the front guide 12 as hereinafter more fully set forth.

FIGS. 3, 4, S, 6, 7, and 8 all illustrate various configurations of two part swimming planes, each comprising a front guide 31? and an arm guide 32 pivotally joined by the transverse hinge 34- to permit hand operation of the front guide by the swimmer arm sleeves. As shown in FIGS. 30, 31, 32 the hands of the swimmer are inserted through the hand opening 36 and grasp the front guide 30 for swimming control purposes. Right and left sleeves 38, 40 extend from the arm guide 32 to secure the arms of the wearer in operating positions.

In FIGS. 11, 12 and 13, I show swimming fins 42 comprising right and left flippers 44, 46 pivotally and separably joined by the longitudinal hinge 52. The flippers may be used singly, but display superior performance characteristics when interlocked and operated in unison. Flippers 44, 4e are each provided with an integrally molded foot pocket 48, S0 and are fabricated to be relatively stiff near the foot pockets and relatively flexible near the trailing edge 54. Rubber or molded plastic may be utilized for this purpose. The distance between the leading edge 56 and the trailing edge may be varied to expose more or less flipper surface to contact the water. As swimmers become stronger and more proficient in the use of the novel flippers, the front to rear distance can be correspondingly increased.

A modified type of arm operated swimming plane is set forth in FIGS. 14, 15, 16, 16A, 17 and 18 wherein adjacent right and left planes 58, 60 are pivotally joined along the longitudinal connecting hinge 62. I prefer to fabricate the planes as vinyl extrusions both from a standpoint of economy in manufacture and function with the arm engaging sleeves 64, 66 integrally formed therewith. When in use, the plane will tend to move backwards due to the resistance of the water. In order to keep the planes from slipping past the elbows of the wearer and thus restricting his activity, wrist securing straps 68 adjustably secured to the planes have been found useful.

A one piece flexible swimming plane 70 is set forth and illustrated in FIGS. 19, 20, 21, 22, and 23 wherein the flexible planes may be fabricated of rubber or vinyl plastic suitably reinforced for the service. In the embodiment illustrated in FIG. 19, a plurality of longitudinally disposed, spaced ribs 72 strengthen the plane 70 and carry the flexible webbing 74 therebetween to provide a unitary construction. A pair of front hand openings 76, 78 are forwardly closed by the reinforced leading edge 80 which must be thin and strong, and preferably constructed of a transverse length of tempered wire 82 completely enclosed in the rubber or vinyl webbing material 84. A securing strap 86 is secured above the trailing edge 88 of the plane 70 and is sized to accommodate both arms of the swimmer to permit maximum flexure and control during the swimming movements. The ribs 72 are fabricated of wire or molded plastic for stiffness in one direction and are preferably covered with the webbing material of rubber or vinyl which may be heat sealed, cemented or molded thereto in any well known manner.

In FIG. 21, I show an alternate method of constructing a one piece swimming plane utilizing a body 91) of flexible plastic sheet or core sheet 92 sealed completely in an enclosing envelope of vinyl plastic 94. The leading edge 96 and trailing edge 98 are sandwiched between metal stiffeners 100, 102 to provide the required rigidity. The one piece swimming planes may be constructed approximately twenty-eight inches wide by eighteen inches deep for swimmers of average ability. However, the dimensions may be increased for stronger swimmers or decreased for novices in accordance with the individual skills of the swimmer.

Referring now to FIGS. 26 and 27, I show a complete swimming suit 104 incorporating in a unitary structure arm guided swimming planes 1%, 108 and leg guided fins 110, 112. Lateral right and left body extensions 114, 116 join the respective planes and fins and aid in guiding the swimmer through the water. The suit 104 may be constructed of vinyl plastic or rubber and is suitably reinforced by a plurality of longitudinal, spaced stiffening ribs 118. It should be noted that both the hands and the feet of the swimmer remain clear of the suit to permit complete hand freedom for grasping during the swimming operations and complete foot freedom for walking or standing when not in the water.

An interlocking seam 120 or zipper permits the arms to be independently moved when dressing or swimming and a similar interlocking seam 122 or zipper facilitates individual leg movements when desired. A hinged joint 126 transversely crosses the suit at shoulder height to permit the swimmer to lower his arms when the arm interlocking seam 12%} is opened. In order to allow a swimmer to readily wear the suit, a body cavity 128 of configuration to roughly conform to the body of the swimmer is integrally molded into the suit 164. A longitudinal zipper 130 or zippers can be provided as required to facilitate easy donning and shedding of the suit. The longitudinal seams 120, 122 and the transverse hinge 126 all cooperate to give the swimmer mobility when on land.

In order to use the swimming plane of FIGS. 1, 2 the arms 132, 134 of the swimmer 136 are inserted through the sleeves 22, 23 24, 25 until the front edge of the opening 28 can be grasped with the thumbs below the front guide 12 and the other fingers above the guide. In this manner, the front guide 12 may be pivoted upwardly and downwardly about the hinge 16 by wrist action on the part of the swimmer and the arm guide 14 may be downwardly pivoted about the hinge 20 by the swimmer bending his elbows.

As best seen in FIGS. 31, 32, the swimming planes of FIGS. 3, 4, 5, 6, 7, 8 and 30 may be used by inserting the wrists of the swimmer through the sleeves 38, 4!} until the front guide 30 is grasped between the fingers and thumb of each hand as best seen in FIG. 32. In this manner, the front guide 30 can readily be flexed upwardly and downwardly as indicated in FIG. 31.

The swimming planes are used to propel the swimmer through the water by grasping the front guide with the hands as above described and swinging it in a rhythmic, paddle-like motion, leading the up-swing and down-swing motion of the arms to cause a hydro-dynamic current action of the water similar to the rolling movements of a porpoise. This action is illustrated in FIG. 28 wherein the front guide 30 and the arm guide 32 are schematically illustrated in sequential positions forming the undulating path 138. When on the upward slope of the path, the front guide 30 is flexed upwardly to lead the swing of the arms in the upward direction. The front guide 30 is then downwardly directed to lead the downward swing of the arms and the attached arm guide 32. In this manner, the swimmer can guide his movements through the water along a course similar to the path 138.

The swimming fins 44, 46 of FIGS. 11, 12 may be utilized in conjunction with the swimming planes by inserting the feet 140, 142 of the swimmer into the pockets 48, 50 in well known manner and connecting the fins along the hinge 52. The fins can then be operated in unison to help propel the body of the swimmer along the path 138 by stroking and coordinating in a manner similar to that presently employed by racing swimmers using the butterfly stroke.

The swimming planes illustrated in FIGS. 19, 21 may be employed by a swimmer 136 in the manner illustrated in FIGS. '24, 25. The leading edge 80 is first grasped by the hands of the swimmer through the openings 76, 78 and the arms 132, 134 are secured to the trailing edge 88 by means of the strap 86. The swimmer may then propel himself forwardly through the water by taking a series of rhythmic strokes. By alternately bending his arms upwardly and downwardly, the swimmer can cause water deflecting forces along the surfaces of the plane 70. The arm curvature of the plane allows for a natural, rhythmic, waving motion.

The swimming suit of FIGS. 26, 27 enables the swimmer 136 to readily propel himself through the water along an undulating path 138 by operating his arms and legs in unison in alternating sequential upward and downward strokes as illustrated in FIG. 29. The eel-like or rhythmic action as shown will cause forward motion.

Although I have described my invention with a certain degree of particularity, disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
