Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise load device which is an exercise machine for improving physical strength.

[0002]

2. Description of the Related Art Treadmills and bicycle ergometers have been conventionally provided as exercise load devices for improving physical strength and measuring physical strength. The former is designed to allow walking or running motion on a belt-shaped floor surface, and the amount of exercise load is made variable by adjusting the speed and inclination angle at which the belt-shaped floor surface is moved. The latter has a bicycle shape including a handle, a saddle, and a pedal, and has a variable load for a pedaling operation.

In recent years, such an exercise load device is equipped with a controller using a computer, and if the above load control is performed by inputting sex, age, set pulse load, etc., the load value corresponding to these settings can be obtained. It is used in the set exercise mode by controlling so that it becomes a light exercise mode, a heavy exercise mode, an interval mode in which light exercise and heavy exercise are repeated, and various exercise modes such as physical fitness measurement mode. There is provided an exercise load that can be applied according to the physical strength of the person.

Here, it is troublesome for the user to input unique data such as his / her sex, age, or physical strength each time he / she uses the exercise load device. To avoid this, these unique data are stored and called at any time. It is desirable to be able to do so. Furthermore, when it is used by an unspecified number of people, as storage means,
A memory card that can be attached and detached is preferable in terms of usability.

In order to satisfy these conditions, there is provided a device in which peculiar data is conventionally stored in a memory card having a backup battery and a cmosRAM, and the peculiar data can be read out by inserting the memory card. There is.

However, since the memory card is expensive, it is actually provided only for business use. On the other hand, if an attempt is made to add the above-mentioned function to a home exercise load device without increasing the cost, first, the RA incorporated in the one-chip microcomputer will be described.
It is conceivable to use M or other RAM, but in this case, not only the system reset at the time of abnormality, but also the data is lost when the power supply is disconnected. Although a magnetic card is relatively inexpensive, it cannot write sufficient information because of its limited storage capacity.

The present invention has been made in view of the above points, and an object of the present invention is to store user's unique data, which is convenient, and to provide at low cost. It is to provide an exercise load device capable of

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments, but any form of exercise load device may be used, but here, as shown in FIGS. The case is shown. In this exercise load device, a pair of stanchions 2 and 3 are erected from a leg frame 1 formed in an X shape, and the stanchion 2 of both stanchions 2 and 3 whose lengths are variable by expansion and contraction. A handle 20 and a controller 8 are provided at the upper end of the column 3, and a saddle 30 is provided at the upper end of the column 3. And both columns 2,
In the part covered by the cover 9 on the leg frame 1 side between the three,
A gear box 4 fixed to a plate 90 spanned between the columns 2 and 3 is arranged.

The gearbox 4 here has a worm wheel 40 and a worm shaft 41 meshing with the worm wheel 40, and the worm wheel 40 is provided with a pedal 50 via a free wheel (not shown). It is connected to the crankshaft 5. A load shaft 44 is connected to the lower end of the worm shaft 41 extending below the gear box 4, and a brake plate 60 is attached to the load shaft 44. The brake plate 60 is formed of an electric conductor such as copper, and the braking device 6 is configured with the electromagnet 61 that positions the brake plate 60 in the gap. 17 in the figure is X
Rollers provided on two of the four grounding portions of the character-shaped leg frame 1, and 19 are roller-like legs provided on height adjusting shafts provided on the other two.

However, if the pedal 50 is operated while sitting on the saddle 30, only the unidirectional rotation is transmitted from the crankshaft 5 via the freewheel to the worm wheel 40.
The load shaft 44 and the brake plate 60 rotate together with the worm shaft 41.
Since the brake plate 60 is placed in the magnetic field of the electromagnet 61, it produces an eddy current and is electromagnetically braked by the eddy current and the magnetic field. This braking force is
It becomes a load for the operation of stepping on and changes depending on the current flowing through the electromagnet 61 and the rotation speed of the brake plate 60. It goes without saying that mechanical braking may be applied to the brake plate 60 by the electromagnet 61.

The braking force of the braking device 6 is controlled by the controller 8. A block circuit diagram of an example of the controller 8 is shown in FIG. 1 and an external view thereof is shown in FIG. The control circuit 80 including a microcomputer as a main component is mounted on the key switch 81, the operation display light emitting display element 82, the buzzer 83, and the user's ear to measure the user's pulse and control the measured value. In addition to a pulse sensor 84 sent to the circuit 80, a sensor 85 for measuring the rotation speed of the brake plate 60, a display unit 87 made of liquid crystal connected via a driver 86, a printer 89, etc., a nonvolatile memory made of an EEPROM. The storage element 88 is connected. As the key switch 81, as shown in FIG. 4, a user selection switch 81a, an exercise mode selection switch 81b, a set value increasing / decreasing switch 81c, a start switch 81d, a setting item changing switch 81e and the like are provided. .

Then, in the storage element 88, in addition to data of items such as personal ID, sex, age, and exercise mode,
Data such as set load, set time, and set pitch are stored for each exercise mode. In this case, the storage element 88 has a small capacity E of about 1 Kbit (128 bytes).
Even with the EPROM, it is possible to sufficiently store the unique data for about four persons. Of course, 1 for each person
Different exercise modes for individuals may be set and used as a menu. Storage element 88 which is an EEPROM
Although it is rewritable, it is non-volatile, so data will not be lost even when the system is reset or the power is turned off.

However, in this exercise load device,
When the user trains for the first time, an average value is input as the initial value, and by increasing or decreasing the set value of each mode while looking at the liquid crystal display, it is possible to set the desired setting. . Then, when the setting is completed and the start switch is pressed, the set value is written in the memory element 88, and the user can perform the exercise in the exercise mode of the load based on the set value.

In the next training, since the data of the user ID selected by the user selection switch 81a is read from the storage element 88, it is not necessary to change the setting, and if the setting value is changed again at this point. After that, when the start switch 81d is turned on and the exercise is started, the changed data is written back to the storage element 88. Writing to the storage element 88 in this case may be performed only when the user gives an instruction for writing.

By the way, in manufacturing, since all bytes of the EEPROM are usually FFh or 00h, if the data is read as it is at the first use after being incorporated in the controller 8, it does not operate normally. Therefore, here, the controller 8 writes the initial value to the storage element 88 when the read data is not normal. Even if the read data is normal, if the value is outside the normal range (for example, when the load value is extremely large), it is desirable to regard it as abnormal and write the initial value.

The memory element 88 may be directly mounted on the substrate in the controller 8. However, if it is detachable from the controller 8 as a card type, the memory element 88 has only one user. In addition to being able to deal with the number of people that can be managed by 88 or more, it is easy to call the specific personal data when the number of users is large. Both the memory element 88 directly mounted on the substrate and the card-type removable memory element 88 may be used. In this case, when the card-type storage element 88 is connected, the card-type storage element 88
It is preferable to prioritize the data written to.

Further, when the card type storage element 88 is used, software for giving a predetermined instruction or action (event) when a distance or time according to training is reached, for example, a place name for each distance according to exercise or the like. By displaying, it is possible to provide software that motivates the user to achieve the goal and encourages the user to continue the exercise. This is a card-type storage element 8
This can be realized by storing the integrated value of the amount of exercise (integrated exercise distance or integrated exercise time), the value to be compared with this integrated value, and the message output when both match in 8 it can. The message data may be provided on the control circuit 80 side.

[0020]

As described above, according to the present invention, the rewritable small-scale non-volatile storage means is provided as the storage means for storing the data necessary for the control by the load control controller. Of course, the unique data can be stored, and since it is non-volatile, this data will not disappear, and since it is small, the cost can be suppressed.

In this case, the storage means is an EEPROM.
Is particularly advantageous in terms of cost, and if it is detachable, it is easy to use.
