Description

This device is a comprehensive trunk strength training machine developed for the purpose of rehabilitation, improvement of physical fitness of elderly people, and improvement of basic physical fitness of people in low physical fitness.

The demand for training machines aimed at improving physical fitness is increasing in recent years. In addition, various devices have come to be used according to the demands of machines specializing in training sites. As an example, gripping the arm lever in a standing position and tilting the footboard with power in the forward or backward direction creates a forward leaning posture or a sliding posture, thereby increasing resistance to motion sickness etc. There is an “equilibrium sense training device” (see Patent Document 1). In this device, the arm lever and the riding board are integrated, and the inclination of the riding board is the same as the inclination of the arm lever. Arm levers are used to maintain posture and are not designed for muscle strength.
The “function training device for rehabilitation” (see Patent Document 2) has a rotating shaft and a motor for transmitting a rotational force to a clutch case with a built-in clutch mechanism attached to a base, and a movement or automatic movement of an arm or a leg. It is structured to be connected to various attachments used in the above. In this device, a movement form is adopted in which one leg or one hand is involved in movement around the rotation axis via an attachment. However, whole body exercise is not considered.

The “martial arts training device” (see Patent Document 3) is a martial arts training machine that uses an electromagnetic load device to rotate or shake a sandbag-like rod-shaped human body dummy via a shaft and a joint. In this apparatus, a movement of rotating the handle is also considered. Although it is a training machine using an electromagnetic load device, it has been developed as a training device for enhancing the basic physical strength for twisting or throwing away a human body.
The “electromagnetic resistance load type trunk muscle training machine” (see Patent Document 4) is a training machine using an electromagnetic load device and using various attachments for muscular strength training that can be attached and detached. In the operation mode of this device, “Japanese boat rowing training” is handled. This is an exercise mode in which a trainee is in a standing posture and moves the lever arm forward and forward. However, this device is not equipped with a power assist device and is intended for training healthy people and athletes, so it is a step-by-step process for people who are in functional recovery (rehabilitation) or who are in low physical fitness. There is no consideration for the use of special training (exercise seats, etc.).

The following step-by-step procedure is effective for achieving motor function recovery (rehabilitation) and motor function improvement using a training machine.
First stage: “A stage where the body is moved depending on the force of another person or device, and the involvement of spontaneous muscle strength is less (power-assisted exercise)”.
Second stage: “A stage in which a person works with the help of another person or device while exerting spontaneous muscle strength (half-assist exercise)”.
Third stage: “A stage in which the person does not have the help of another person or device and works independently by spontaneously exerting muscular strength (completely independent movement)”.
No training device has been developed so far that aims to gradually recover and improve motor function based on this concept.
The “trunk strength training machine with power assist” of the present invention is based on the long-standing empirical fact that the “Japanese boat rowing exercise” is effective for the exercise form of health promotion. It is a training machine that was developed from the beginning.

The present invention is a training machine in which a Japanese boat rowing exercise is possible from the stage using power assist, and includes a lever arm and a power assist device, and the basic operation of pushing and pulling the lever arm is a power assist device. It is a power assist integrated trunk muscle strength training machine that can be performed automatically or semi-automatically using the, and can also be implemented as a self-sustaining exercise according to the physical strength and physical condition of the user. The power assist device preferably has both a resistance load device for self-sustained exercise, and selects and uses the exercise load mode in any of the sitting posture, the middle waist posture, and the standing posture.

According to the present invention, since the power assist device is used, motor function recovery (rehabilitation) and motor function improvement by a stepwise procedure can be achieved.

The basic motion form of this device is to hold the handle lever with both hands (or one hand) and select either “posture sitting on chair”, “mid-back posture supported by waist”, or “standing posture”. The operation is to “push” the arm in the distal direction (forward) of the body and “pull” from the distal direction to the proximal direction (front side). You can “push” the lever arm only by extending the arm, but if the arm strength is weak or the force is not strong, hold the arm lever and bend the elbow to the lever arm. If the entire trunk is tilted forward so as to lose weight, the lever arm can be "pushed" forward. On the other hand, “pulling back” the lever arm toward you is a “rebounding action from a leaning posture”, and it is possible to “pull” the lever arm by raising the trunk to move the weight backward. It is.
This kind of operation of “pushing” and “pulling” the lever arm is an operation that uses not only the muscles of the arms and shoulders but also the muscles of the back, chest, abdomen, and hips. Highly effective in training leg and buttocks muscle groups.
Pushing and pulling the lever arm in a standing position is equivalent to the “Watashi rowing exercise”. “Watune rowing exercise” has traditionally been used as a basic exercise to improve physical fitness and martial arts training. It has been incorporated in. The “push” and “pull” movements of the lever arm are accompanied by the muscle strength of the trunk, so that the posture maintenance ability of the trunk is enhanced and the “trunk deep muscle” that connects the arm and leg muscles to the trunk It is effective. Moreover, since the trunk is shaken back and forth to exert its power, an improvement in standing posture balance and an improvement in walking ability are expected.
In order to realize such a training effect, this device is devised so that the above-described three steps (power assist type exercise, half-assist type exercise, and fully independent type exercise) can be executed step by step. .

FIG. 1 shows an embodiment of the “trunk strength training machine with power assist” of the present invention.
This training machine includes a lever arm (1), a lever arm control unit (2), a posture control sheet (3), an operation / display panel (4), and a base (5).
FIG. 2 is a structural diagram of the lever arm control unit.
The lever arm control unit includes a power motor (6), a resistance load device (7), a pulley a (8), a belt (9), a pulley b (10), an angle detection switch (11), and a lever arm (1).
At the time of “power assist type exercise”, the power motor (6) is driven, and the rotational force is applied to the lever arm (1) via the resistance load device (7), the pulley a (8), the belt (9) and the pulley b (10). ) At this time, the resistance load device (7) is set to transmit the rotational force of the power motor (6) to the pulley a (8) without slipping. In addition, the angle detection switch (11) can arbitrarily set the operating range of the lever arm (1).
During this operation, when the force of “pushing” or “pulling” the lever arm (1) of the user exceeds the rotational force of the power motor (6), the resistance load device (7) slips, "Half assist type exercise" is possible.
At the time of “completely self-supporting motion”, the rotation of the power motor (6) is locked, and the slip of the resistance load device (7) can be set arbitrarily. At this time, the rotational force of the lever arm (1) due to the “push” and “pull” motion is transmitted to the resistance load device (7) via the pulley b (10), the belt (9) and the pulley a (8).

FIG. 3 is a diagram illustrating a configuration of the “posture control sheet” and a sheet setting example.
A seat cushion (12), a seat back (13), a seat lifting and lowering device (14), and a seat front and rear device (15) are shown.
During the “sitting posture” movement, the seat cushion (12) and the seat back (13) can be adjusted to appropriate positions by the seat lifting device (14) and the seat front-rear device (15).
At the time of the “middle waist posture” exercise, the seat back (13) can be placed in a posture in which the waist is left behind by storing the seat cushion (12) that can be lifted backward.
During the “standing posture” exercise, the seat cushion (12) and the seat back (13) which are not required in the standing posture can be moved rearward to ensure a sufficient space necessary for the exercise.
FIG. 4 is a structural diagram of the “operation / display panel”.
This panel displays “resistive load of lever arm”, “operating speed of lever arm”, “operating range of lever arm”, “sheet position” and “number of times the lever arm is pushed and pulled” data With functions, etc., it is possible to operate the machine intensively at one place.

The power assist device of this machine is not only for training of healthy people and athletes but also for functional recovery (rehabilitation) exercise and consideration of the use of step-by-step training for people with low physical fitness (exercise seats) Etc.) has been made.
In addition, training in various exercise postures is possible by using the posture control sheet as an accessory device depending on the shape of the lever arm and creating a posture in which the user can exercise.
In addition, the operating range of the lever arm can be set in advance using the operation / display panel, and if the lever arm is subjected to a force that exceeds the speed of the lever arm and the load applied to the lever arm, the resistance load Sliding friction occurs and the user can control the movement of the lever arm.
