Description

Walking track variable walking exercise equipment {AN APPARATUS FOR WALKING EXERCISE WITH VARIABLE WALKING TRACE}

The present invention relates to a walking gait variable walking exercise device, and more specifically, to adjust the exercise trajectory of the legs and feet according to the user's physical conditions or required exercise conditions, to increase the exercise and treatment effect, and to gain interest and immersion in the exercise. The present invention relates to a walking gait variable walking exercise device that can be promoted.

Exercises are carried out for a variety of purposes, including fitness, health promotion, and rehabilitation. Among them, the walking exercise is an aerobic exercise that does not cause a great burden on the body, and is being spotlighted as a suitable exercise for young and healthy people, as well as for the physically ill patients and the elderly.

Walking exercise can be done by walking on roads or sports grounds, but due to the limitations of time and place according to the living environment and physical constraints of the person who wants to exercise, the exercise is mainly performed using walking exercise equipment installed indoors. It is often done.

There are many kinds of such walking exercise mechanisms, and in general, there is a flat moving type walking device called a treadmill. This is to obtain a predetermined movement effect by the user stepping on the belt conveyor that is moved at a constant speed, there is an advantage in that the walking movement is performed in the same position as the actual walking. However, there is a disadvantage that the belt conveyor and the motor and the controller for driving and controlling the same are expensive, and cannot be used in a place where power is not supplied. In addition, simply walking on the usual walking habits on the belt conveyor, it is easy to feel bored during exercise, it was difficult to expect the therapeutic effect, such as improving the walking habits of the elderly and patients.

Some walking mechanisms allow the user to pedal and apply walking force without using power. As an example of such a mechanical walking exercise mechanism, there is a lifting type exercise mechanism provided with a pair of pedals that can be lifted up and down, and having a spring or a pneumatic cylinder that elastically supports each pedal. This has the advantages of simple structure, low cost, and walking movement in a relatively narrow place, but it is easy to get up and down by simply raising and lowering both feet, and it is far from actual walking. There is a problem that the exercise is also falling through the treatment and health promotion through walking exercise.

Another example of the mechanical walking exercise mechanism is that the front and rear of the pedal is connected in a link structure so that when the user takes a walking motion, the pedal moves and rotates along a predetermined trajectory so that the movement is performed. This walking type walking exercise mechanism has the advantage of performing a similar exercise to the actual walking, compared to the lifting type exercise equipment, but because the pedal is configured to move only along a predetermined angle and trajectory, the exercise method is simple, causing interest There is still a problem that the effect is weak, and the exercise and the health promoting effect are inferior because various exercise cannot be performed according to the individual physical condition, condition, and demand of the exerciser.

Referring to the operation of the walking exercise device of the present invention configured as described above are as follows.

First, the user raises both feet on the left and right pedals 114, respectively, to take the ready position. At this time, by holding the handles 132 on both the left and right sides with both hands to stabilize the posture. In this state, one leg is extended forward, the opposite leg is pulled backward, and the arms are extended and pulled so that the left and right sides face in opposite directions, respectively, similar to the actual walking. Accordingly, one side of the two stepper 110 is advanced and the other side is reversed, the handle portion 130 connected in accordance with the movement of each stepper 110 is rotated to the front and rear, respectively. In addition, the driving pulley 151 rotates as the handle 130 rotates, and the driving pulley 151 is provided with a resistive force by the rotating load body 154 to provide an exercise load of appropriate strength.

When the one side stepper 110 is moved forward, the load is concentrated to the stepper 110 by the natural center of gravity movement and the user's artificial weight movement, the load applied to the stepper 110 is increased Accordingly, the pedal support arm 113 is rotated downward while the pedal 114 is moved downward. At this time, the opposite stepper 110 is retracted and the pedal 114 is rotated upward. After being advanced and retracted to a certain limit, each stepper 110 is retracted and advanced again in the opposite direction, and each pedal 114 is raised and lowered. In addition, the pedal 114 is rotated so that the angle of the foot naturally rises or falls as the stepper 110 and the pedal 114 move.

Through the repetition of this operation, each pedal 114 forms an elliptical walking trajectory while inducing physical motion similar to the actual walking. Further, the walking movement is performed along various trajectories according to the load movement of the user. It is possible to exercise in a natural posture without harming the body, and to walk movements having various trajectories according to the user's physical condition and needs. In addition, in order to perform a smooth continuous operation, the user must artificially move the weight by paying attention, so that the interest and concentration of the exercise can be improved, thereby enabling a more effective walking exercise.

During the operation as described above, the left and right of each stepper 110 and the handle portion 130 is interlocked with each other by the left and right interlocking device 150, the operating range is the control link 133 Is adjusted according to the position of engagement. That is, as the coupling position of the control link 133 is closer to the center of rotation of the rotation arm 131, the rotation range of the rotation arm 131 increases, so that the operation range of the stepper 110 and the handle part 130 is increased. On the contrary, as the coupling position of the control link 133 moves away from the rotation center of the pivoting arm 131, the operating range of the stepper 110 and the handle part 130 is reduced. Accordingly, the operating range of the stepper 110 and the handle unit 130 can be easily adjusted by changing the coupling position of the control link 133 according to the physical condition of the user or the desired exercise intensity and the part, and thus, the user can be further adjusted. It is possible to provide an optimized gait effect.

On the other hand, in the above-described embodiment illustrates a structure in which the rotating load body 154 is connected to the drive pulley 151 by the belt 153 in order to apply the exercise load to the left and right interlocking device 150, but is not limited thereto. The movement load is applied through the self-weight of the constituent member or the rotational resistance of the coupling part, etc., so that a separate rotation load body 154 is not required. In this case, the driving pulley 151 may be replaced by a simple rotating body, and the rotating body may be formed in various forms such as a disk or a shaft.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
