YARDAGE INDICATOR FOR HANDCART |
摘要 |
A yardage indicator to be mounted on a manually driven handcart, such as a golf cart, having a friction wheel adapted to ride on either wheel of the cart to drive a reduction gear mechanism as the cart wheel rotates, the output of which is connected to a pointer which rotates around a dial to accurately and visually indicate the yardage traveled by the cart. The pointer is frictionally connected to the gear mechanism output shaft to permit a manual resetting of the pointer to any mark on the dial without affecting the gear mechanism. The indicator is provided with adjustable mounting means to compensate for different cart designs and different diameters and tracks of cart wheels.
