It is about a rowing machine that is designed to be enjoyed.

[Prior art]

Conventionally, most of the main rowing machines commercially available conventionally use hydraulic pressure or air pressure as a load device. Therefore, the load control of the load device in such a type of rowing machine is a hydraulic cylinder or The load value is controlled to the target value by turning (adjusting) the knob attached to the pneumatic cylinder. Therefore, it is very difficult to control the load value, and it is impossible to adjust with high precision, so it is difficult to perform an efficient rowing motion. In addition, various quantitative data during the rowing extracted from the load device and the like are not sufficiently displayed, so it is very difficult to accurately grasp the amount of exercise and physical strength of the person. There were various problems such as certain problems.

The present invention has been made in view of the above circumstances, and is provided with a drive system unit in the front, a slide rail extending from the drive system unit in the rear, a footrest part in front of the slide rail, and an operator on the upper part. A slide type seat for seating is attached to each of the drums, and a drum around which the operator sits on the seat in the drive system unit and winds a rope of a predetermined length that is towed by a rowing operation, and an operator pulls it to the side of the drum. A return spring for rewinding the unwound rope to the state before towing is housed together, and a predetermined transmission means for transmitting the rotation of the drum to the load side of the drum, and an eddy current load device rotated by the transmission means. With wearing

Display means for visually recognizing the stroke length of the rope extracted from the drum extracted by the device, the rope traction pitch, the distance, the traction peak watt, the traction set watt, the traction average watt, the traction consumed calories, etc. By pulling the rope wound around the drum, it is as if rowing an oar equipped on an actual boat. It is possible to experience the boat feeling,
In addition, when pulling the rope, it is possible to set various conditions such as age, sex, physical strength, beginner, expert, etc. of the operator in the control conditions of the eddy current load device, and thoroughly manage the rowing movement.

Hereinafter, the usage procedure and operation of the rowing machine according to the present invention will be described in detail based on the above embodiment.

"Usage Guidelines" (1) First, before starting the rowing exercise, that is, seat 5
Before sitting on, the operator M selects and sets a predetermined selection button on the operation panel described above in consideration of his physical strength, exercise experience, and the like.

(2) Then, as shown in FIG. 1 and FIG. 2, sit down on the seat 5, put both feet on the foot rest 4 in front, and bend the body forward (in a state of leaning forward) to move both hands forward. Stretching substantially horizontally toward the front, grasping the grip 7a at the center of the front operation panel firmly by pulling the oar, pulling as much as possible by bending the arm and extending the body backward at the same time, The rope 7 connected to the grip 7a is pulled out from the drum 6 for a predetermined length.

(3) The drum 6 in which the rope 7 is wound by pulling the rope 7
Makes a predetermined rotation, and the rotational movement of the drum 6 is transmitted by means of a transmission sprocket 9, a first chain 10, a rotary shaft 11, a small sprocket 12, a second chain 13, a small sprocket 14,
Rotating shaft 15, timing pulley 16 and timing belt 17
Is transmitted to the eddy current load device 18 at the final stage via.

(4) The first rowing exercise is completed by the above.

(5) After that, the grip 7a is returned to the front. The rope 7 in this state is the drum 6
Since it is unwound by a predetermined rotation by the return spring 8 provided side by side, it can be smoothly wound in the original state without slack.

(6) Then, in the present embodiment, the above rowing exercise is repeated for about 6 minutes to carry out a full rowing exercise.

By the way, the movements of the rope 7, the drum 6 and the eddy current load device 18 during the rowing motion are accurately detected by the rotation speed detection sensor 19 and the rotation speed detection sensor 20, respectively. The detected predetermined detection signal is input to the arithmetic processing unit 22 in the subsequent stage and to the predetermined display means 23 arranged on the operation panel 21.

The various exercise conditions set before the rowing exercise described in (1) above are set based on various data such as one's body position, age, sex, etc. Normally, the load during exercise is the actual rowing exercise. It is desirable to simulate to match

That is, for example, the force curve at the time of actual rowing shown in FIG. 6 is input to the microcomputer in advance, and the magnitude of the load of the eddy current load device 18 is changed while detecting the displacement of the seat during movement. It is possible to experience the feeling of rowing at the time of actual rowing if processing is performed as much as possible.

In particular, in the above case, as shown in the same figure, if the power can be set to various types from large to small in accordance with the physical strength of the person using the rowing machine, the width of the rowing motion is extremely wide. It is also extremely easy to set.

Further, since the calculation processing device 22 calculates the relationship between the displacement and the force to calculate the work amount and the work amount is displayed on the display means 23, it is possible to accurately grasp how much exercise has been performed. is there.

"Exercise mode (outline)" A (isopower mode) (1) Set an exercise load that suits your physical ability and start exercise.

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

In other words, when the set load is 100 watts, for example, the more you pull in the rowing operation, the faster the speed increases, and the load at that time increases, but when it exceeds 100 watts,
Reduce the torque on the load side so that 100 watts is maximized. By performing such control, it becomes possible for a general person to achieve the rowing exercise in a planned manner without difficulty.

B (rowing power mode) (1) When rowing starts at an arbitrary stroke pitch,
The load is set and controlled so that the person can always row at maximum power. Rowing is performed for a predetermined time (for example, 6 minutes) under such control.

(2) Conditions for setting the load The setting of the load condition in the rowing power mode is carried out in a form accurately simulating the resistance when the rowing blade moves underwater.

That is, if the force that the blade receives from water is F, and the speed of movement in water is v, If C · A · S · is k, then F = kv ² .

C: Resistance coefficient 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 the v is controlled. . Here, if k is set to a value close to the resistance of water, a simulation with high rowing accuracy will be performed. On the other hand, in the actual rowing, the shape of the oar, the viscous resistance of the water, etc. are determined, so the same resistance will occur when rowing the oar even for people with physical strength and those without physical strength, so the resistance is too heavy or light. Although there is a case where the user feels too much or too much, the rowing machine of the present invention, as described above, is configured so that the strength of the load, that is, k, is automatically set. You can enjoy the rowing exercise comfortably.

It is possible to set various conditions for each person, etc., to thoroughly manage the rowing movement, and structurally in front of the machine. Is arranged, and a slide type seat is provided behind the drive system unit so that the rowing position of the operator who pulls the rope from the drum is approximated to the all-rowing position in the actual boat.
