[Prior art]

Conventionally, most of the main rowing machines on the market use hydraulic pressure or pneumatic pressure as a load device, and therefore the load control of the load device in these types of rowing machines is performed using a hydraulic cylinder or a hydraulic cylinder. The load value is controlled to the desired value by adjusting knobs etc. attached to the pneumatic cylinder. For this reason, it is extremely difficult to control the load value, and moreover, it is impossible to make highly accurate adjustments, making it difficult to perform an efficient rowing exercise. In addition, various quantitative data extracted from the loading device etc. during rowing are not sufficiently displayed.
Therefore, there have been various problems such as it is very difficult to accurately grasp the increase in physical strength including one's own exercise amount.

[Means and effects for solving the problems] The present invention has been made in view of the above circumstances, and includes a drive system unit at the front, a slide rail extending from the drive system unit at the rear, and a slide rail that extends from the drive system unit at the rear. A footrest is attached to the front of the rail, and a sliding seat for the operator to sit is attached to the upper part, and a drum is provided in the drive system unit on which the operator sits on the seat and winds a rope of a predetermined length to be pulled by a rowing motion. , - A return spring is housed on the side of the drum for rewinding the rope pulled out by the operator to the state before it was pulled, and a predetermined transmission means for transmitting the rotation of the drum to the load side of the drum. In addition to being equipped with an eddy current load device, a rotation speed detection sensor of the drum and a rotation speed detection sensor of the eddy current load device are installed at predetermined positions within the drive system unit, and a predetermined detection signal is detected from the detection signals detected by these rain detection sensors. Equipped with an arithmetic processing device that calculates the power mode of the computer and a display means that visually or audibly recognizes the arithmetic processing data extracted by the arithmetic processing device, by pulling a rope wound around a drum. , you can experience the feeling of rowing as if you were rowing with oars equipped on a certain actual boat, and when pulling the rope, the control conditions of the eddy current load device, such as the age of the operator, Conditions such as gender, physical strength, beginners, and experts can be set to ensure thorough self-control of the rowing exercise.Structurally, the drive system unit is placed at the front of the machine, and the drive system unit is located at the rear of the drive system unit. Equipped with a sliding seat, the rowing position of the operator who pulls the rope from the drum is designed to approximate the rowing position of the operator in an actual boat, so the rowing movement is extremely comfortable and does not require any strain on the body position. You can enjoy it. Furthermore, regarding the rope return mechanism after towing, a return spring is installed coaxially with the axis of the drum around which the rope is wound, so there is no slack in the return rope and no unnecessary torque is applied to the drum or eddy current load device. Since there is no work involved, simulations can be performed very smoothly and it is possible to obtain highly accurate display data.

Further, calculation processing for calculating, for example, the stroke length of the rope, the rope pulling pitch, the distance, the peak wattage, the set wattage, the average wattage, the calorie consumption, etc. from the rotational data of the drum or the load value data of the eddy current load device. In addition to adopting a microcomputer as the device,
Since visual display means and audible display means are used as means for displaying the arithmetic processing data of the arithmetic processing unit, such as rope stroke length, distance, peak wattage, and set wattage, the configuration is very compact. The aim is to provide a rowing machine equipped with various excellent functions.

Hereinafter, the usage and operation of the rowing machine according to the present invention will be explained in detail based on the above-mentioned embodiments.

``Usage Requirements wIj (11) First, before starting the rowing exercise and before sitting on the row seat 5, the operator M should press the predetermined selection button on the operation panel mentioned above, taking into consideration his own physical strength, exercise experience, etc. Select and set.

(2) After sitting down, as shown in Figures 1 and 2, sit on the seat 5, put both feet on the footrest 4 in front, bend your body forward (slouching position Bi), and use both hands. Stretch it forward in a substantially horizontal direction, firmly grasp the grip 7a located at the approximate center of the front operation panel as if pulling an oar, and pull with all your might by bending your arms and simultaneously stretching your body backwards. , the row 17 connected to the grip 7a is pulled out from the drum 6 by a predetermined length.

(3) The drum 6 around which the row 17 is wound rotates in a predetermined manner by the pulling of the row 17, and the rotational movement of the drum 6 is transmitted by a transmission means,
That is, the drive sprocket 9, the first chain 10, the rotating shaft 1
1, the final stage eddy current load device 1 via the small sprocket 12, second chain 13, small sprocket 14, rotating shaft 15, timing pulley 16, and timing belt 17
8.

(4) With the above steps, the first rowing exercise is completed.

(5) After the grip 7a is returned to the front, the rope 7 in this state is rewound by a predetermined rotation by the return spring 8 attached to the drum 6. It smoothly rolls back into its original state without loosening.

(6) Then, in this embodiment, the rowing exercise described above is repeated for about 6 minutes to perform a thorough rowing exercise.

Incidentally, the movements of the rope 7, drum 6, and eddy current load device 18 during the rowing movement are accurately detected by the rotation speed detection sensor 19 and the rotation speed detection sensor 20, and these rain detection sensors 19 and 20 The detected predetermined detection signal is inputted to the arithmetic processing unit 22 at the subsequent stage and is displayed on a predetermined display means 23 arranged on the operation panel 21.
・In addition, the various exercise condition settings before rowing exercise explained in (11) above are based on your body position, age,
Although settings are made based on various data regarding gender, it is usually desirable to simulate the load during exercise to match the actual rowing exercise.

That is, for example, the force curve during actual rowing shown in FIG. 6 is manually input into a microcomputer in advance, and the magnitude of the load on the eddy current load bag 218 is changed while detecting the displacement of the seat during exercise. If the processing is done as much as possible, it will be possible to enjoy the feeling of rowing while actually rowing.

In particular, in the above case, as shown in the figure, if the power of the rowing machine can be set in several ways, from high to low, depending on the physical strength of the person using the rowing machine, the range of rowing motion can be greatly expanded. It is also extremely easy to set up.

Furthermore, the calculation processing unit 18 calculates the amount of work by calculating the relationship between displacement and force, and the amount of work is displayed on the display means 23, so it is possible to accurately grasp how much exercise has been performed. It is.

r Exercise form (overview) A゛ (isopower mode) <11 Set an exercise load that suits your physical ability and start exercising.

(2) During exercise, control the load so that it does not exceed the set load.

In other words, when the set load is, for example, 100 watts, the stronger you pull during rowing, the faster the speed will increase.
At that time, the load increases, but if it exceeds 100 watts, the torque on the load side is reduced and controlled so that 100 watts is the maximum. By controlling in this way, it becomes possible for even the average person to accomplish the rowing exercise in a planned manner.

B (Rowing Power Mode) When a person starts rowing at a given stroke pitch, the load is set and controlled so that the person can always row with maximum power. Rowing is performed for a predetermined period of time (for example, 6 minutes) under such control.

(2) Load setting conditions The load conditions in the rowing power mode are generated in a form that accurately simulates the resistance particularly when the rowing plate moves through water.

That is, if the force that the blade receives from the water is F, and the speed at which the blade moves in the water is V, then F=C-A-3.- If C-A-3 is k, then F=kv''.

C: Coefficient of resistance between water and blade A Area of blade S: Density of water In the rowing machine of the present invention, V is detected by the rotation speed detection sensor 20, and the load (torque) F corresponding to that V is detected.
control. If k is set to a value close to the resistance of water, a highly accurate rowing simulation can be achieved. On the other hand, in actual rowing, the shape of the oar, the viscous resistance of the water, etc. are fixed, so whether you are physically fit or not, the same resistance occurs when rowing the oars, so the resistance may be too heavy or However, as mentioned above, with the rowing machine of the present invention, the degree of load strength, that is, k, can be automatically set automatically. You can enjoy rowing exercise comfortably.

A return spring for rewinding the drum to the state before towing is installed, a predetermined transmission means for transmitting the rotation of the drum to the load side of the drum and an eddy current load device are installed, and a predetermined position in the drive system unit is installed. A rotation speed detection sensor of the drum and a rotation speed detection sensor of the eddy current load device are attached to the drum, and an arithmetic processing device calculates a predetermined power mode from the detection signals detected by these rain detection sensors, and the arithmetic processing device Equipped with a display means to visually and audibly recognize the extracted computational data, by towing the rope wound around the drum, you can row a boat just as if you were rowing an oar equipped on an actual boat. You can experience the sensation, and when pulling the rope, the control conditions of the eddy current load device,
For example, various conditions such as the operator's age, gender, physical strength, beginner, expert, etc. can be set, and the drive system unit is structurally located at the front of the machine to ensure thorough self-control of the rowing exercise. However, we installed a sliding seat behind the drive system unit to allow the operator to pull the rope from the drum in a rowing position that is close to the all-rowing position in an actual boat. You can enjoy the rowing exercise in an extremely comfortable manner without straining yourself at all. Furthermore, regarding the rope return mechanism after towing, a return spring is installed coaxially with the axis of the drum around which the rope is wound, so there is no slack in the return rope and no unnecessary torque is applied to the drum or eddy current load device. Simulations can be performed very smoothly without any work, and it is possible to obtain highly accurate display data. Furthermore, from the rotation data of the drum or the load value data of the eddy current load device, for example, the stroke length of the rope, the rope pulling pitch, the distance, the peak wattage,
A microcomputer is adopted as a processing device that calculates set wattage, average wattage, calorie consumption, etc., and the processing data of the processing device, such as rope stroke length, distance (peak wattage, set wattage, etc.) is displayed. Since the visual display means and the audible display means are adopted as the means, it is possible to provide a rowing machine equipped with various excellent functions such as a very compact structure.
