Abstract
An instrument for indicating proper racquet-handle grip circumference for a given human-hand-characteristic size comprises a plate having a plate-longitudinal-alignment pointer and a scale spaced from the pointer for indicating characteristic length, and between the pointer and scale a plate orienting and laterally aligning fin for insertion between third and fourth human digits; transparent-scale and offset-scale embodiments are described and method is disclosed.
Claims8
A hand-measuring system for determining appropriate racquet handle circumference to fit particular human hands, comprising:
- means for aligning with the palm and fingers of a hand including a plate, a fixed fin as said plate at an intermediate location and projecting perpendicularly from one side thereof said fixed fin proportioned for longitudinally aligning with and extending between second and third fingers of a hand and maintaining longitudinal orientation of the plate;
- a fixed pointer on the plate in longitudinal alignment with said fin and proportioned for positioning by longitudinal sliding of the plate to point at the center of a palm of a hand, and fixed scale means on the plate for indicating distance along said alignment from the pointer, when the pointer is pointing at the center of a palm of a hand, to the end of the third finger of the hand.
