Abstract

Acoustic signal apparatus, especially used as time tapper for sportive interval trainings, having a signal giving device (3) producing acoustic signals, said signal giving device (3) being controlled by a master clock device (1) to produce a plurality of acoustic pulses mutually shifted by predetermined clock intervals. Mutually different acoustic pulses are produceable by the signal giving device (3), and the signal giving device (3) is controlled by the master clock device (1) in such a way that the mutually different acoustic pulses are mutually time shifted alternatingly in cyclical repetitions for predetermined clock intervals, said clock intervals being adjustable independently of each other by the adjusting device (13, 14) of the master clock device (1).

Claims

1. An athletic timer device comprising:

first, second and third sound generation means, each for generating a respective acoustic signal in response to first, second and third respective control signals;

a first counter means for counting a first interval, for manually selecting the duration of said first interval, and for outputting said first control signal to said first sound generation means when said first interval has been counted;

a second counter means connected to receive said first control signal for counting a second interval upon occurrence of said first control signal, for manually selecting the duration of said second interval, and ford outputting said second control signal to said second sound generation means when said first interval has been counted; and

a third counter means responsive to occurrence of said second control signal for counting a third interval, for manually selecting the duration of said third interval, and for supplying said third control signal to said third sound generation means when said third interval has been counted.

2. The athletic timer device of claim 1 wherein said first, second and third sound generation means and said first, second and third counter means are contained in a first housing, and further including a second housing having a display means for visually displaying the counting of said first, second and third time intervals, and wherein said first housing detachably fits together with said second housing to form a timer unit, said first housing further including power source means for energizing said first, second and third sound generation means and said first, second and third counter means, such that said first housing is operational when detached.

3. The timer device of claim 2 wherein said second housing includes means for operating said display as a stop watch when said first housing is detached therefrom.
