Abstract
An aquatic training aid includes a paddle member for wearing by a swimmer, a variable diaphragm disposed within the paddle member, the variable diaphragm including a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades. The variable diaphragm is adjustable to change the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture. Controlling the aperture enables the swimmer to adjust the resistance provided by the aquatic training aid when it is moved through water.
Claims12
An aquatic training aid comprising:
- a paddle member for wearing by a swimmer;
- a variable diaphragm disposed within the paddle member, the variable diaphragm comprising a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades;
- and
- wherein the variable diaphragm is adjustable to change the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture.
An aquatic training aid comprising:
- a paddle member for wearing by a swimmer;
- at least one strap comprising a tubular string for securing a hand of the swimmer to the paddle member wherein the paddle member further comprises a plurality of recesses that allow at least one end of the at least one strap to be stringed through some of the plurality of recesses;
- a variable diaphragm disposed within the paddle member, the variable diaphragm comprising a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades wherein the plurality of fitted blades are maintained in a friction fit within the housing keeping the aperture substantially fixed in shape and size when the paddle member is moved through water;
- and
- wherein rotation of the housing changes the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture.
