Abstract

PROBLEM TO BE SOLVED: To enable a person to be measured to do treading action at predetermined constant interval regardless of the magnitude of his treading force. SOLUTION: A treading instruction interval Tc is sequentially to make the actual treading interval Tb close to a preset target treading interval Ta by designated ratios by a treading instruction interval calculating means 42, and a speaker 28 is driven at the calculated treading instruction interval by a treading instructing device driving means 44 to output a sound signal for instructing a person to be measured to do treading action. So if the person to be measured simply performs the treading action according to the treading instruction, the treading interval Tb is gradually made closer to the target treating interval Ta by designated ratios, and finally the treading action can be taken at the treading interval Tb substantially equal to the target treading interval Ta. Thus, if the first treading instruction interval Tc is set comparatively long, a person to be measured with small treading force can also easily perform the treading action at a predetermined constant interval.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stepping-in device for stepping-type exercise equipment that allows an exerciser to perform stepping operations at predetermined intervals.

[0002]

2. Description of the Related Art For example, an ergometer or the like is known as a stepping-type exercise device that allows a person to perform a stepping operation at predetermined intervals. By the way, when exercising using an ergometer, the power L (the amount of work per unit time) near the point where the aerobic exercise switches to the anaerobic exercise, that is, the so-called AT point (anaerobic work threshold) ), It is known that the exercise efficiency of the exerciser increases, and the power L near the AT point shows a different value for each exerciser according to the cardiopulmonary function of the exerciser. Therefore, such a power L near the AT point is obtained as a target value for each exerciser, and the load (rotational resistance) of the ergometer is adjusted so that the actual power L matches the target value. ing.

Since the power L during exercise is proportional to the number of revolutions N of the pedal and the load T of the pedal, respectively,
If the rotational speed N of the pedal is too low, the actual power L cannot be matched with the target value unless the load T of the pedal is made very large, so that the pedal can be depressed within the optimum rotational speed range. , A sound or visual display is output at predetermined intervals, and a stepping-instruction device that allows the athlete to perform a stepping-in operation in accordance therewith has been considered.

[0004]

However, even when a sound or visual display is output at a predetermined interval, an exerciser such as a child or an elderly person, who has a weak stepping force, steps on the rhythm from the beginning. It is difficult to perform the operation, the stepping operation is delayed with respect to the stepping instruction, it is difficult to synchronize with the instruction, and there are cases where the exercise according to the exercise prescription cannot be performed accurately.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to perform a stepping operation at a predetermined interval easily regardless of the magnitude of the stepping force of an exerciser. An object of the present invention is to provide a stepping-in instruction device for a stepping-type exercise apparatus that can be performed.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a stepping-in device for stepping-type exercise equipment for causing a person to perform stepping operations at predetermined intervals. (B) a step sensor for detecting that the user has stepped on and that the other foot has been stepped on;
Stepping interval calculating means for sequentially calculating a stepping interval representing a time interval from the time when one foot of the exerciser is depressed to the time when the other foot is depressed, based on a signal from the stepping sensor; ) Based on the relationship set in advance so that the actual stepping interval approaches the preset target stepping interval by a predetermined ratio, a stepping instruction is output to the exerciser based on the stepping interval sequentially calculated by the stepping interval calculating means. A step-instruction interval calculating means for sequentially calculating a step-instruction interval representing a time interval to perform, and (d) a step-in instruction for instructing an exerciser to perform a stepping action based on the step-instruction interval sequentially calculated by the step-instruction interval calculating means. And a step-in indicator driving means for driving the box.

[0007]

According to the present invention, the stepping-instruction interval calculating means sequentially calculates the stepping-instruction intervals such that the actual stepping-in distance approaches a preset target stepping-in interval by a predetermined ratio. Accordingly, the stepping indicator for instructing the exerciser to perform the stepping operation at the stepping instruction interval is driven, so that the exerciser merely performs the stepping operation according to the instruction from the stepping indicator, and the actual stepping interval is set to the predetermined target. It gradually approaches the stepping interval by a predetermined ratio, and finally the stepping action is performed at a stepping interval substantially equal to the target stepping interval.Therefore, by taking a relatively long initial stepping instruction interval, even an exerciser with a weak stepping force can be used. It is possible to easily perform the stepping operation at a predetermined constant interval.

In FIG. 3, in step SA1, it is determined whether or not an ON signal has been input from a depression sensor 18 provided on the left foot pedal 12. If this determination is affirmative, the measurement of the step interval Tb _n-1 is terminated in step SA2 corresponding to the step interval calculating means 40, and the step interval Tb _n-1 is detected.

[0016] Then in step SA3, the measurement of the depression instruction interval Tc _n is allowed to start. Subsequently, in step SA4 corresponding to the stepping-instruction interval calculating means 42, an expression

As described above, according to the present embodiment, the actual stepping interval Tb is set to the predetermined target stepping interval Ta by the stepping instruction interval calculating means 42 (SA4, SA10).
Is sequentially calculated by a predetermined ratio determined based on the coefficient K, and the speaker 28 or the display lamp 30 is driven by the stepping indicator drive means 44 (SA6, SA12) at the stepping instruction interval Tc. Since the sound or light signal for instructing the stepping operation to the exerciser is output, the exerciser simply performs the stepping operation in accordance with the instruction, and the actual stepping interval Tb is set to the predetermined target stepping interval Ta. Since the stepping action is gradually approached at a rate, and finally the stepping action is performed at the stepping interval Tb substantially equal to the target stepping interval Ta, the first stepping instruction interval Tc is relatively long, so that even the exerciser with a weak stepping force can easily perform. Can perform the stepping operation at a predetermined constant interval.
