Patent number: 5540591Abstract: An exercising, e.g., waterless swim training apparatus is disclosed having a frame and a support for the trainee's torso where the torso support is movable along a curve that is convex to the ground below, thus simulating the rocking, or rolling motion experienced in swimming. The frame and body support provide an obstruction free region so that the user can practice breast stroke, butterfly, back stroke and free style strokes without touching any part of the frame, ground, etc. with his/her fingers. The obstruction free zone is roughly a circular hemi-cylinder, extending below the trainee's body. A resistance mechanism is provided to resist motion of the user's hands. The resistance mechanism presents a force versus velocity relationship that simulates the force versus velocity relationship experienced during swimming. One embodiment uses a hydraulic pump in connection with variable valves and a fluid reservoir.Type: GrantFiled: October 21, 1994Date of Patent: July 30, 1996Inventor: Michael P. Doane

Patent number: 5472391Abstract: An aquatic exercise device which has a dual configuration of (1) a hand-held buoyancy swimming kickboard; and (2) a buoyancy device worn around the human's midsection. The device is a buoyant board element which is substantially elongated, of greater length than width, and having large surface areas at opposite sides thereof. Affixed to and/or projecting from the buoyant board element are opposing limbs of band elements. When secured around the human midsection, the device is used in deep water to support the human in a relatively or substantially vertical position. This allows upright exercise while the human is freely suspended with the head and most or all of the neck above water, and the lower extremities bearing no weight, feet not touching bottom. When the band is folded and/or wrapped and fastened around the board or removed, the board can be used as a kickboard. An auxilliary buoyant element is provided for location in different selective positions relative to the band and/or board.Type: GrantFiled: December 29, 1993Date of Patent: December 5, 1995Inventor: Sanford S.

Patent number: 5429564Abstract: An exercising, e.g., waterless swim training apparatus having a frame and a support for the trainee's torso. The torso support is movable along a curve that is convex to the ground below, thus simulating the rocking, or rolling motion experienced in swimming. The frame and body support may be arranged to provide an obstruction free region so that the user can practice breast stroke, butterfly, back stroke and free style strokes without touching any part of the frame, ground, etc. with his/her fingers. The obstruction free zone is roughly a circular hemi-cylinder, extending below the trainee's body. A resistance mechanism is provided to resist motion of the user's hands.

Patent number: 5136621Abstract: Swim/sporting event timer/counter. A waterproof housing has upwardly projecting digital displays and two spaced ultrasonic receivers. A swimmer wears an ultrasonic transmitter tuned to ultrasonic receivers. by measuring the time differential for the ultrasonic signals from the transmitter to reach the receivers in the housing, the position of the swimmer (i.e., in front of, directly over, or behind the housing), is determined. Laps are identified by determining when the transmitted signal changes from being received by the two receivers by an increasing time differential to being received by a decreasing time differential. Each time the swimmer passes over the housing, the numbers on the display are inverted so that the swimmer may look down into the water and see the time regardless of which direction the swimmer is traveling in the lane or other predetermined course.Type: GrantFiled: December 11, 1990Date of Patent: August 4, 1992Inventors: Mitchell, David E., Dean Lurker

Patent number: 4258914Abstract: A training device for competitive swimmers which can be adjustably mounted on a swimmer's body part and, in operational use, provides predetermined resistances of varying degrees to the swimmer's normal movements, causing him to exert greater effort, the resistances being generated by weights selectively and removably mounted within the device. Exploitation is made of the muscle as a sensory organ in generating a heightened awareness of muscle or tendon or joint movement.Type: GrantFiled: December 26, 1979Date of Patent: March 31, 1981Inventor: Ronald P.
