Abstract

A time measuring device for determining and evaluating the running times of a plurality of runners in a running track, which includes a way and a return path includes two timers (1, 2), which are actuated by a signal pulse as a start signal or stop signal, and two pulse in the start / target point and at the turning point. By a changeover circuits (5), the connection of the start / finish pulser (3) and the reversing pulser (4) with alternately one of the timers (1 or 2) for generating the start or stop signal is established during the connection of each other timepiece (1 or 2) is blocked. A comparison device (8) with output device (9) serve to output the difference as a competition result.

Description

The invention relates to a time measuring device for determining and evaluating the running times of several runners in a running track according to the preamble of claim 1. This time measuring device is known by the DE10331447A1 ,

This time measuring device is used for a competition to determine the fastest runner.

The object of the invention is to provide a time measuring device for a running game in which everyone and even the slowest can have a sense of achievement.

The solution results from claim 1 or claim 2.

Common to these solutions is the advantage that for each runner two signals are determined separately for the trace and for the return and these signals are compared and output. This is done according to claim 1 by two timers each for the trace and the return and a comparison device which compares the speeds with each other and outputs the difference as the competition value. According to claim 2, only one timer is needed, which measures the time for the trace and runs backwards in reverse of the runner, so that the difference between the times for trace and return as a competition value is output directly.

In the following embodiments of the invention will be described with reference to the drawing.

Show it:

1 and 2 schematically the circuits for the time measuring device for executing the two solutions according to claim 1 or 2. It will be used for functionally identical elements like reference numerals. The description for 1 applies to 2 unless the specifics are highlighted.

The run takes place between the start / finish point 6 to the turning point 7 (Way 20 ) and from the reversal point 7 back to the start / finish point 6 (Way back 21 ,

In the start / finish point 6 is the pulse generator 3 , z. As a light barrier, here executed as a button that the runner presses at startup. This will be a pulse 10 generated as a start signal for the way. The start signal is via the bistable switch 14 forwarded to the pulse switch 16 through which the timer 1 is set in motion. The start signal 10 is also called a switching pulse 18 the bistable switch 14 abandoned and causes the switching of the bistable switch with a set delay 14 from its rest position to the position shown here as open. This will establish the connection between the start / finish pulser 3 and the timer 1 interrupted and the connection between the reverse pulser 4 and the timer 1 produced.

The runner now reaches the reversal point 7 and activates here the pulse generator reverse pulse generator 4 , again a light barrier, here executed as a button.

As a result, a pulse is generated, which as a stop signal 11 for the way and as a start signal 12 for the way back.

The stop signal 11 for the way over is the bistable switch 14 in the previous by switching pulse 18 set switching position forwarded to the pulse switch 16 through which the timer 1 is stopped. The measured time is stored and the comparator 8th signaled.

The start signal 12 for the way back is over the bistable switch 15 forwarded to the pulse switch 17 through which the timer 2 is set in motion. The start signal 12 is also called a switching pulse 19 the bistable switch 15 abandoned and causes the switching of the bistable switch with a set delay 15 from its rest position to the position shown here as open. This will make the connection between the reverse pulser 4 and the timer 1 interrupted and the connection between the start / finish pulser 3 and the timer 2 produced.

The runner now reaches the start / finish point 6 and activates the pulse generator start / target pulse generator 3 , As a result, a pulse is generated, which as a stop signal 13 for the way back.

The stop signal 13 for the way back is over the bistable switch 15 in the previous by switching pulse 19 set switching position forwarded to the pulse switch 17 through which the timer 2 is stopped. The measured time of the return path is stored and the comparator 8th signaled.

The comparator outputs the measured time values as a difference to the output device 9 , z. B. a printer.

In the execution after 2 or claim 2 is only a timer 1 related. This has the property that he can record the time forward and then -. B. by reversing - can count backwards again. This will make the timer appear possibly an output device, z. As a printer, directly the time difference between the zeitejn for outward and return.

The polarity reversal of the timer happens because the output signals of the pulse switch 16 . 17 have an opposite polarity. Otherwise, the control of the pulse switch takes place 16 . 17 in the manner described above.
