  • Patent number: 5505454
    Abstract: Disclosed herein is a golf swing practice device or training aid which aids a golfer in developing and/or maintaining the rhythm and dynamics of a proper swing based principally on the smooth application of an accelerating centrifugal force to the clubhead. The device includes a shaft having a lower portion and a grip disposed over its upper portion. An elongate tubular elastomeric member, whose bottom end may be weighted, is coaxially affixed to the lower portion of the shaft. At least a portion of the length of the tubular elastomeric member extends below the tip of the shaft, thereby being unsupported, and is stretchable in response to the centrifugal force imposed on the member during practice swinging of the device.

  • Patent number: 5405139
    Abstract: A golf swing training device comprised of a shaft with a grip over which a tubular elastomeric member is fitted. The tubular elastomeric member has one end affixed adjacent to the grip and the other end may be weighted. A portion of the tubular elastomeric member is unsupported by the shaft so that it is free to flex in all planes. The tubular elastomeric member is entirely unrestrained along its longitudinal axis, so that it is free to extend in response to centrifugal forces. The shaft which extends centrally through part of the tubular elastomeric member offers sufficient support to allow the device to be swung rhythmically back and forth without collapsing, while the flexibility and elasticity of the tubular elastomeric member provide a unique feel of swinging the clubhead.
