Waterproof digital lap counter
First Claim
1. A waterproof lap counter comprising:
- a waterproof counter case of sufficiently small size to be contained within the palm of a hand of a swimmer or within the underside of a foot of a swimmer, said counter case housing all components necessary to count laps and including(i) an outer housing having an opening;
(ii) an inner housing slidably and nonrotatably mounted within the opening of said outer housing;
(iii) means for biasing said inner housing outwardly from said outer housing;
(iv) a numeric display;
(v) pressure actuated means for providing an input signal indicative of a lap count including a count switch having a plurality of spaced contacts attached to said inner housing and a contact member attached to said outer housing, said plurality of spaced contacts being spaced apart from said contact member by said biasing means to define an open position of said count switch, said inner housing being operable to move inwardly relative to said outer housing to define a closed position of said count switch in which said spaced contacts abut said contact member to produce said input signal upon abutment of said inner housing against a wall of a swimming pool during the normal stroke of a swimmer having the waterproof lap counter attached to an extremity;
(vi) means for incrementally counting receiving said input signal and providing an output signal operable to increment said number display; and
(vii) a power source providing power to said numeric display and said incrementally counting means; and
means for attaching said waterproof counter case to an extremity of a swimmer whereby operation of said pressure actuated means automatically increments said numeric display thereby indicating the total number of laps traversed.

Abstract
A waterproof digital lap counter automatically counting and indicating the number of laps traversed by a swimmer having the lap counter attached to a hand or foot comprises a LCD array including a digital counter, driver and LCD embedded within a sealed inner housing which is slidably and nonrotatably supported in an outer housing. Counting and indication of laps traversed occurs automatically and is triggered by abutment of the lap counter against the side of the swimming pool during the swimming stroke or flip turn of the swimmer. Abutment of the lap counter against the side of the pool momentarily closes a switch which sends an input signal to the LCD array representative of a lap traversed. The LCD array counts and provides a visible indication of the number of input signals received which corresponds to the total number of laps traversed.
