Abstract

The swimmer''s training device includes an elongated pocket assembly having sidewalls hingedly connected together in a sideby-side relation and foldable end walls extended between and interconnected with the sidewalls. The end walls are of a size to permit movement of the sidewalls to a spread apart position to form an angle of substantially 90*. With the pocket extended transversely of the longitudinal axis of the body of the swimmer, one of the sidewalls is secured flat against the forward side of the swimmer''s torso so that the pocket will open in the direction of swimming movement. Thus, during swimming the pocket is opened by the action of the water against the second sidewall which functions as a resistance member to impede the passage of the swimmer through the water. The resistance member is of a hinged construction to provide an outer foldable section that is foldable against the inner section of the resistance member to vary the resistance offered by the resistance member against the swimmer''s movement through the water.

6% AQ4OM Arm/mew RESISTANCE MEMBER ATTACHED TO A SWIMMER SUMMARY OF THE INVENTION The swimmer training device is of a unit construction formed of materials that are waterproof and relatively yieldable so as not to injure the swimmer should he accidentally strike the device. It is compact, efficient in operation to strengthen a swimmer and is readily secured to the swimmers torso for use in either swimming on the stomach or on the back without interfering with a free normal movement of the swimmer. By virtue of the foldable construction of the resistance member the device is quickly adjustable to provide a variable resistance for use by swimmers of different aptitudes or at different stages in their training.

DETAIL DESCRIPTION OF THE INVENTION Further objects, features and advantages .of the invention will become apparent from the following description when taken in connection with the accompanying drawings in which:

FIG. I shows the device in assembled position on the body of a swimmer;

FIG. 2 is a perspective view of the device showing a resistance member that forms a part thereof illustrated in a folded position;

FIG. 3 is a perspective view illustrated similar to FIG. 2 showing the resistance member in an unfolded position;

FIG. 4 is an enlarged sectional detail view as seen along the line 4-4 in FIG. 3;

FIG. 5 is a developed plan view of the device with some parts broken away and other parts shown in section to more clearly show its construction; and

FIG. 6 is a sectional view taken along the line 6-6 in FIG. 5.

With reference to the drawings the swimmer'training device of this invention, indicated generally as 10, is shown in FIG. 1 as applied to the body ofa swimmer l1 and projected from the front side of the torso 13 when the device is used for stomach swimming. For back swimming the device would be reversed so as to project from the back side of the torso.

The device 10 (FIGS. 2 and 3) is ofa unit construction and includes an elongated pocket or scoop assembly 14 that has sidewalls l6 and 17 hingedly connected together at 18 in a side-by-side relation. For the purpose of convenience of description the sidewalls I6 and I7 will hereinafter be referred to as a fixed wall and movable wall, respectively. Foldable end walls 19 are interconnected to the fixed wall 16 and movable wall 17 for movement to unfolded positions, shown in FIGS. 3 and 4, to provide for the movement of the movable wall or resistance member 17 to a position in a plane substantially normal to the plane of the fixed wall 16.

End extensions

21 and 22 on the fixed wall 16 are secured to a strap section 23 and cooperating buckle section 24, respectively, which are connectable together in a well-known manner. The fixed wall 16,

extensions

21 and 22, and

strap sections

23 and 24 thus form an adjustable strap unit for encircling the swimmers torso 13 with the movable wall or resistance member 17 projected outwardly from the torso.

The pocket assembly 14 (FIG. 5) includes a pair of identical body members 26 and 27 of an irregular shape arranged in a back-to-back relation and formed of a flexible sheet material such as a vinyl plastic. Only the body member 26, therefore, will be described in detail and like parts of body member 27 will be designated by like numbers having the suffix A.

The body member 26 is integrally formed with a movable wall section 28 of a generally semicircular shape and a fixed wall section 29 ofa generally rectangular shape. Cutaway portions 31 in the wall section 29 form generally triangular shaped end portions 32 on the movable wall section 28, and connecting portions 33 on the side of the wall section 29 remote from the movable wall section 28.

With the body members 26 and 27 superposed a pair ofpliable backing members 34 and 36'formed of a stainless steel sheet material are inserted between the members 26 and 27'at the movable wall sections 28 so as to extend longitudinally of such sections between the triangular end portions 32 in a transversely spaced relation (FIGS. 4, 5 and 6). As clearly shown in FIG. 5 the adjacent innersides 37 and 38 of the

backing members

34 and 36, respectively, are of a straight form. The outer side of the backing member 34 is of a curvature corresponding to the curvature of the movable wall sections 26 on the outer side of the backing member 36 is curved concavely inwardly.

The body members 26 and 27 are sewed together along the marginal edges thereof by stitching, indicated at 39, and the

backing members

34 and 36 are maintained in fixed positions by

stitchings

41 and 42, respectively. The strap section 23 and buckle section 24 are inserted between the connecting portions 33 at the time the body members 26 and 27 are sewed together along their marginal edges, with additional reinforcing stitches 43 being provided.

As thus far described it is seen that the movable wall I7 is hingedly connected to the fixed wall 16, by virtue of the flexibility of the body members 26 and 27, along the junction line therebetween indicated at 18. Likewise, it will be noted that the portions of the movable wall 17 corresponding to the

backing members

34 and 36 are hingedly connected between their adjacent innersides, as indicated at 44, to provide for the front section of the wall or resistance member 17 being foldable toward the fixed wall 16 as shown in FIG. 2. This folded position of the front section of the movable wall 17, as defined by the backing member, 34, is retained by a usual fastening means that includes a button member 46 secured to the backing member 36 and a coacting socket member 47 secured to the backing member 34.

To complete the assembly of the pocket 14 the end triangular portions 32 (FIGS. 4 and 5) of the movable wall 17 have their free ends sewed to the end portions of the fixed wall 16 along the stitch lines shown at 48, whereby those parts of the end portions 32 located between the

stitch lines

42 and 48 on the movable wall 17 form the foldable end walls 19 of the pocket assembly 14.

In the use of the device 10 for stomach swimming, and as shown in FIG. 1, the device 10 is strapped about the body of the swimmer 11 with the fixed wall 16 flatagainst the forward side of the torso 13 so that the pocket assembly 14 faces or opens in the direction of forward movement of the swimmer. The pocket assembly 14 is thus free of any interference with a side arm movement of the swimmer along with leaving the swimmers legs completely unobstructed. On a forward movement of the swimmer the water acting against the movable wall or resistance member 17 moves such wall away from the fixed wall 16 until the end wall members 19 are extended to their unfolded positions shown in FIGS. 3 and 4. The movable wall 17 thus functions to resist the forward movement of the swimmer through the water by its scooping action in directing water into the pocket assembly 14.

To reduce the resistance effect of the wall 17 to the forward progress of the swimmer it is only necessary to fold the from section thereof along the hinge line 44 to a folded position within the pocket assembly 14, which folded position is maintained by the snap fastening members 46 and 47. The resistance member 17 is thus readily adjustable to vary the water impedance effect of the device 10 to accommodate varying swimming aptitudes and strengths of swimmers being trained.

For back swimming the pocket assembly 14 is arranged to project outwardly from the back side of the swimmers torso 13 so that it opens in the direction of forward movement of the swimmer.

By virtue of the vinyl plastic construction of the pocket assembly 14, along with the flexibility of the

backing members

34 and 36 the device 10 is readily carried by the swimmer so as to conform to the configuration of the torso 13 and to eliminate any injury to the swimmer should he accidentally strike the device with his arms during swimming, or hit the device against an obstruction such as a chair or the like while waiting his turn for training instruction.
