Abstract
A tubular golf club shaft is formed with an area made of fiberglass through which you can see. A swing speed indicating device is fastened inside the shaft and visible through a fiberglass area so that you can read the speed indicated on the device. When the shaft is swung, an indicator moves inside the shaft to position an indicator along a scale on the shaft or the device so you can read various parameters derived from the velocity with which the club is swung. The shaft is formed by inserting a strip of translucent material such as fiberglass to overlap with adjacent strips of graphite material that form the shaft.
Claims18
A golf club shaft having a longitudinal axis, comprising a continuous wall encircling the longitudinal axis and forming a tubular shaft having a swing point located a predetermined distance from a grip end of the shaft, the wall having a segment of translucent material that is sufficiently translucent to see through located along a length of the longitudinal axis;
- further comprising a swing velocity indicator located within at least a portion of the translucent material and viewable through that translucent material;
- wherein the velocity indicator is calibrated to indicate at least one of the velocity of a golf club head on the end of the shaft, the velocity of a ball struck by a golf club head on the end of the shaft, or the distance of projected travel of a ball struck by a golf club head on the end of the shaft.
A golf club shaft having a longitudinal axis, comprising a continuous wall encircling the longitudinal axis and forming a tubular shaft having a swing point located a predetermined distance from a grip end of the shaft, the wall having a segment of translucent material that is sufficiently translucent to see through located along a length of the longitudinal axis;
- further comprising a swing velocity indicator located within at least a portion of the translucent material and viewable through that translucent material;
- wherein the velocity indicator comprises a tube enclosing a seismic mass slidably disposed in the tube and connected to a spring resiliently urging the mass toward a first end of the tube and a velocity indicator positionable by the seismic mass.
A golf club shaft having a longitudinal axis, comprising a tubular shaft having a wall encircling the longitudinal axis and forming a tapered shaft having a swing point located about 14 inches from a grip end of the shaft, the wall having a segment of translucent material that is sufficiently translucent to see through with a portion of the translucent section located at the swing point;
- and a measurement device located inside the shaft and having an indicator the position of which changes depending on the velocity with which the shaft is swung, with at least a portion of the indicator being viewable through the translucent section.
