SWING FORCE INDICATOR FOR A PLAYING PIECE OF SPORTS EQUIPMENT A swing-force indicator for a playing piece of sports equipment intended to be swung in the playing of a game, including an elongate housing, an elongate shaft, and bearings disposed adjacent opposite ends of the housing for mounting the shaft for lengthwise turning movement therein. A manually engageable finger piece is rigid on one end of the shaft, and a weight member having an indicator is slidable along the shaft. A compression spring on the shaft engages the weight member to bias it toward one end of the shaft, to a starting position. The weight member has a pawl and the shaft has teeth cooperable with the pawl to hold the weight member in various adjusted positions remote from the starting position against the action of the compression spring. The shaft has a smooth track on which the pawl can alternately ride when the shaft is turned by the finger piece, thereby to enable return of the weight member to a starting position under the action of the compression spring. There is provided a resilient detent finger in the housing for yieldably holding the shaft in position for engagement of the teeth thereof by the pawl. The advantage of the present construction over the devices of the prior art is that reduced cost is realized, due to a simplification in the assembly of the individual components. |
