Lap timing device
First Claim
1. A lap timing device for swimmers for use during a training session, said device comprising:
- a non-depressible means for detecting a beginning of a training session, said training session having a number of laps;
proximity sensing means for detecting an end of each lap of the training session;
means for measuring a time duration of the training session;
means for detecting an end of the training session; and
means for indicating an average time duration per lap.

Abstract
A lap timing device for swimmers utilizes a proximity sensor to detect the completion of each lap a swimmer swims during a training session. The device, which is preferably portable and in the form of a starting block of standard AAU dimensions, is placed adjacent an edge of a swimming pool. The number of laps of the training session are input and the swimmer stands on the diving platform of the device. When the swimmer dives off of the platform, a switch starts a clock/counter in the device. The proximity sensor, preferably an ultrasonic transducer, detects the completion of each lap. When the predetermined number of laps is counted by the device, an alarm sounds, indicating to the swimmer the end of the training session, and the total swim time, average time per lap, fastest lap time and slowest lap time are displayed. The device automatically provides the pertinent information about a training session to the swimmer, allowing the swimmer to concentrate on his swimming without worrying about losing track of which lap he is on.
