Abstract
Abstract A digital indicating instrument for a physical training device, in particular a rowing device, includes a sensor fixed rigidly to a basic frame of the training device and sensor trip element fixed to an operating part, in particular to a sliding seat of the rowing device. An evaluation circuit responds to control pulses generated by the sensor during the passing movement of the trip element and determines together with the training time output-related data, which are displayed on a display screen. A training time measuring device is started by control pulses of the sensor for an automatic determination of the training time. A stop device stops the training time measuring device if within a preset time interval no control pulse is generated by the sensor. A suppressor suppresses at the start of training at least the first control pulse, in order to prevent unintentional starting of the training time measuring device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
202 words
A digital indicating instrument for a physical training device having a basic frame on which an operating part to be moved for training purposes is movably guided, comprising: sensor trip element fixed to the operating part; sensor means mounted rigidly relative to the basic frame for responding to a passing movement of the sensor trip element and generating control pulses; evaluation means for responding to the control pulses and producing signals; and display means displaying the signals of the evaluation means, said evaluation means including control means responsive to the control pulses of said sensor means and training time measuring means controllable in a start-stop manner and generating time signals representing training real time, the time signals being displayed by the display means, said training time measuring means being responsive to the control pulses indicating a start of training, said control means stopping said training time measuring means if within a time interval of a preset length an initial control pulse is not succeeded by a further control pulse, said control means suppressing a predetermined number of control pulses in order to delay said training time measuring means for indicating a start of training when said training time measuring means is stopped.
Claim 2
Dependent Claim
202 words
A digital indicating instrument for a physical training device having a basic frame on which an operating part to be moved for training purposes is movably guided, comprising: sensor trip element fixed to the operating part; sensor means mounted rigidly relative to the basic frame for responding to a passing movement of the sensor trip element and generating control pulses; evaluation means for responding to the control pulses and producing signals; and display means displaying the signals of the evaluation means, said evaluation means including control means responsive to the control pulses of said sensor means and training time measuring means controllable in a start-stop manner and generating time signals representing training real time, the time signals being displayed by the display means, said training time measuring means being responsive to the control pulses indicating a start of training, said control means stopping said training time measuring means if within a time interval of a preset length an initial control pulse is not succeeded by a further control pulse, said control means suppressing a predetermined number of control pulses in order to delay said training time measuring means for indicating a start of training when said training time measuring means is stopped.
Claim 3
Dependent Claim
70 words
A digital indicating instrument according to claim 1, wherein said evaluation means further comprises pulse rate measuring means for generating a signal which is displayed by said display means so as to represent a repetition rate of the control pulses, said control means suppressing a preset number of control pulses generated by the sensor in order to delay the pulse rate measurement when said training time measuring means is stopped.
Claim 4
Dependent Claim
35 words
A digital indicating instrument according to claim 2, wherein said control means suppresses each initial control pulse generated by said sensor means for both said training time measuring means and said pulse rate measuring means.
Claim 5
Dependent Claim
36 words
A digital indicating instrument according to claim 3, wherein the control means suppresses a second control pulse generated by said sensor means for said training time measuring means, but not for said pulse rate measuring means.
Claim 6
Dependent Claim
33 words
A digital indicating instrument according to claim 1, wherein the physical training device is designed as a rowing device having a movably connected seat, said sensor trip element being attached to said seat.
Claim 7
Dependent Claim
52 words
A digital indicating instrument according to claim 5, wherein said evaluation means further includes a pulse counter for generating a signal which is displayed by the display means so as to represent a number of control pulse pairs succeeding the present number of control pulse which is suppressed by said control means.
Claim 8
Dependent Claim
31 words
A digital indicating instrument according to claim 1, wherein the physical training device is a stationary bicycle having a pedal crank, said sensor trip element being attached to said pedal crank.
Claim 9
Dependent Claim
47 words
A digital indicating instrument according to claim 1, wherein the evaluation means further includes reset means for responding to an operation of a reset button in a time interval of a predetermined length to reset said evaluation means for supplying signals to said display means to display.
