Description

Exercise equipment for improving hamstring flexibility

The present invention relates to an exercise device, and more particularly, to an exercise device for improving hamstring flexibility to stimulate the hamstring to improve flexibility.

Hamstrings are the muscles that make up the thigh, including the semiimbrasus, semitendinosus, and biceps femoris. They are moved by two joints of the hip and knee that exist between these muscles, which are characterized by easy tension and build-up. The flexibility of the hamstring is used for the diagnosis of cerebral palsy, and is very important in terms of rehabilitation and sports medicine for the elderly, the disabled, and athletes.

On the other hand, the hamstring as described above should be sufficiently stretched when a person squat or bends his back. Otherwise, in the process of performing the above operation, the spine cannot be straightened, and convexly curved toward the back, causing back pain as pressure is applied to the intervertebral disc, and in severe cases, may cause or deepen the disc.

Accordingly, it is necessary to increase the length of the hamstring and make it flexible. This is usually done through stretching, which is an exercise method, such as repeating the action of lying on one side with legs crossed and lifting up toward the upper body. This is an exercise to stretch the hamstring while hanging the rubber band on the sole and pulling the leg with your hand to pull the leg toward the upper body. A similar exercise is to stretch one hamstring with one leg on a support at a constant height, while bending the waist.

Figure 6 is an exemplary view of the user's upper body in the exercise device according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings FIGS. 1 to 6.

Figure 1 is an exemplary view showing the overall configuration of the exercise device according to the present invention, Figure 2 is an exemplary view showing an exploded main configuration of the exercise device according to the present invention.

As shown, the exercise equipment for improving hamstring flexibility according to the present invention includes a femoral stimulation pole 200. The femoral stimulation pole 200 is formed as an area supporting the user's buttocks and thighs, and is formed in a plate shape having a constant thickness so that the upper surface of the thigh stimulation 200 may be generally flat. A stimulation device is formed on the upper surface so that the user can stimulate the femoral hamstring while sitting on the femoral stimulator 200.

The femoral stimulation pole 200 is formed to form a constant height on the floor, so that the user can stimulate the hamstring by sitting on the femoral stimulation pole 200 as if sitting on a chair. This can be achieved by the support leg 120, the support leg 120 is formed on the body frame 100 is formed in a chair shape. The body frame 100 may be formed by being woven into a chair shape using a metal rod, and the femoral stimulation pole 200 is formed in a portion corresponding to the seat plate in the chair.

The femoral stimulation pole 200 may be provided separately and prefabricatedly installed in a portion corresponding to the seat plate in the body frame 100. For example, a space is formed in a portion corresponding to the seat plate, and rails are formed to the left and right of the space, so that the femoral stimulation pole 200 is assembled to be drawer-type along the rail. Thus, when the femoral stimulation pole 200 is installed in a prefabricated manner, the femoral stimulation pole 200 is separated and placed on the floor to be used for stimulating the hamstring.

The support leg 120 is preferably formed to be adjustable in height. The two legs are connected to form a support leg 120, but one of the tubes is fitted into the other tube, and a plurality of pin holes are formed in the longitudinal direction to match the positions of the pin holes formed in the two tubes to form pins. You can adjust the length by inserting. Of course, it is also possible to automatically adjust the height with an electric cylinder. Through this, it is possible to use while adjusting the height of the femoral stimulator 200 according to the user's physical condition.

The femoral stimulation pole 200 may be formed to be inclined downward from the front side (the user's knee side, hereinafter the same) to the rear side (the user's hip side, the same hereinafter). As a result, when the user sits on the femoral stimulator 200, the knee is higher than the hips and the femoral part is pulled toward the upper body, and force is applied in a direction to naturally increase the hamstring even if the upper body is erected.

Here, the inclination angle of the femoral stimulation pole 200 can also be formed to be adjustable to a required degree, so that the position of the femoral stimulation pole 200 can be fixed with a pin or a bolt while lifting or lowering the front side, or The electric cylinder may be installed to be configured to adjust the front height of the femoral stimulation pole 200. By adopting various known height adjustment configurations, the height can be adjusted.

On the other hand, the separately provided femoral stimulation pole 200 may be formed with a protrusion 204 on the front bottom surface. When the protruding portion 204 protrudes at a constant height, and the femoral stimulation pole 200 is separated from the body frame 100 and used on the floor, the femoral stimulation pole 200 is the same as when it was previously installed on the body frame 100. ) Is inclined downward from front to back.

The stimulation device may be a stimulation roller (220). Of course, the configuration is not limited to the stimulation roller 220, and the structure that stimulates the hamstring as it appears, or a device that exerts electrical stimulation or vibration, can be replaced with any other configuration that can stimulate the hamstring as desired. In the present invention, it is assumed that the stimulation device is a stimulation roller 220 as shown.

The stimulation roller 220 is formed to reciprocate back and forth to stimulate the user's hamstring while reciprocating back and forth according to an external signal. The femoral stimulation pole 200 forms an empty interior, and a roller guide path 202 is formed on the upper plate in the front-rear direction so that the pole roller 220 can reciprocate along the roller guide path 202. At this time, only a portion of the magnetic pole roller 220 is installed in a state protruding out of the roller guide path 202, thereby protruding the protruding portion to the upper surface of the femoral stimulation pole 200 to stimulate the hamstring.

The height at which the pole roller 220 protrudes may be formed to be adjustable as necessary. Through this, the user can control the degree of stimulation of the hamstring while adjusting the height at which the stimulation roller 220 protrudes. In addition, the magnetic pole roller 220 may be formed to be supported by a spring to move up and down elastically in a certain range. This is a configuration that can be adopted to compress the hamstring elastically according to the user's body condition while absorbing shock.

Exercise equipment for improving the flexibility of the hamstring according to the present invention includes a calf support (300). It is formed in front of the femoral stimulation pole 200, the calf support 300 forms a shape to support the calf. It is formed to form a certain length and width to support the calf. If the shape can support the calf, it is free to select and form the shape.

The calf support zone 300 may be formed on the body frame 100 or may be formed by being directly coupled to the femoral stimulation zone 200. The calf support 300 is coupled to the body frame 100 or the femoral stimulation band 200 as an axis, and is formed to be separated as necessary. As it is coupled to the axis, it is formed to be able to rotate like a watch pendulum and adjust the angle. It becomes possible. And the position is fixed to the angle is adjusted.

The calf support zone 300 supports under the knee at the leg of the user sitting in the femoral stimulation zone 200. Therefore, when the calf support 300 is rotated and lifted upward, the user's knees are lifted upwards and the legs are stretched, resulting in an increase in the hamstring.

The calf support 300 may be formed to be adjustable in length. For example, a structure in which two rods of different diameters are connected to each other, and a corresponding hole is formed in the two rods to adjust the length by fixing and inserting a pin into the hole while adjusting the length. Alternatively, a structure in which the length is adjusted by power may be adopted by forming the rod including an electric cylinder in which it is driven.

The exercise device for improving hamstring flexibility according to the present invention includes a belt 150. The belt 150 may be formed on the femoral stimulation pole 200, or may be formed on the body frame 100, and when the user sits on the femoral stimulation pole 200, the femoral stimulation pole 200 is positioned at the point where the femur is located. It is formed transversely.

With the belt 150 formed as described above, it is possible to restrain the user's thigh sitting on the thigh stimulation zone 200. When the user's thigh is constrained by the belt 150, the thigh is prevented from being lifted in the process of the user's exercise, thereby helping to exercise stably.

The exercise device for improving the flexibility of the hamstring according to the present invention may be provided with a backrest 140. The backrest 140 is formed at the back of the femoral stimulation pole 200, or may be formed at the rear end of the femoral stimulation pole 200 or may be formed in the body frame 100. It is installed between a pair of backrest rods 142 and the backrest rods 142 having a lower end coupled to the femoral stimulation pole 200 or the body frame 100, and is formed of a sponge roll 144 in which sponges are accumulated on the shaft rods. It can be, the shaft rod is preferably coupled to be rotated on the backrest rod 142, the sponge roll 144 is preferably installed to be rotated.

The backrest 140 may be fixed or formed to adjust an angle. The user adjusts the angle of the backrest 140 in the process of exercising, thereby allowing the upper body to exercise while not falling over a certain angle.

Here, only the sponge roll 144 formed on the top of the sponge rolls 144 formed on the backrest 140 is installed on the backrest rod 142, and the remaining sponge rolls 144 are provided on the backrest 140 in the body frame 100. ) It can be installed on the backrest support 160 formed by standing on the back. Therefore, in the process of adjusting the angle of the backrest 140, only the sponge roll 144 formed on the top end rotates like the backrest rod 142. This is a configuration for the user to adjust the angle of the backrest 140 in a state where the waist is bent so that the sponge roll 144 formed at the top end supports only the upper portion of the pelvis.

The sponge roll 144 formed on the uppermost end may be formed to adjust the height. Accordingly, it is possible to use the backrest 140 while adjusting the height of the sponge roll 144 formed at the top according to the user's physical condition or the degree of bowing the upper body. The configuration for adjusting the height is formed by forming a plurality of coupling holes in the longitudinal direction between the backrest rods 142, such that the shaft rod of the sponge roll 144 is coupled to any one of the coupling holes, or the longitudinal direction of the backrest rods 142 A long hole is formed and a shaft rod of the sponge roll 144 is moved to move along the long hole, and a method in which a bolt is fastened to the shaft rod at a point to fix the position may be adopted.

The exercise device for improving hamstring flexibility according to the present invention includes a handle 130. The handle 130 helps the user to maintain the posture by holding the hand when the user is standing or leaning forward. Therefore, it is preferable to be formed in a position that can be held by the hand when the upper body is erected and a position that can be held by the hand when it is bent. For example, it is formed on the body frame 100 on both sides of the femoral stimulation pole 200 or both sides of the femoral stimulation pole 200 so that the user can grasp the upper body and the front or thigh portion of the femoral stimulation pole 200 There may be a configuration that is formed on the body frame 100 at the front of the stimulation table 200 so that the user can grasp when the upper body is bowed. The handle 130 may be formed to be adjusted in length to adjust the length according to the user's physical condition.

3 is an exemplary view showing the internal configuration of the femoral stimulation band according to the present invention.

The forward and backward reciprocation of the pole roller 220 may be achieved by the actuator 240. A rail 242 is formed in the front-rear direction along the inner center of the femoral stimulation pole 200, an actuator 240 is moved along the rail 242, and magnetic pole rollers 220 are coupled to both sides of the actuator 240. do. The axis of the magnetic pole roller 220 can be fixed to the actuator 240 on both sides with separate brackets or the like. The actuator 240 receives an external signal and reciprocates along the rail 242, and as a result, the magnetic pole roller 220 reciprocates.

Here, the movement distance of the actuator 240 may be formed to be adjustable in stages. That is, it is possible to stimulate the hamstring while setting the moving distance of the stimulation roller 220 when the user is exercising by setting the moving distance in steps such as short distance, middle distance, and long distance using the remote controller.

Figure 4 is an exemplary view showing a state of adjusting the angle of the backrest and the calf support of the exercise device according to the present invention.

An angle adjusting device may be formed to adjust the angle of the calf support 300. The angle adjusting device may be an electric cylinder 400 in which a rod is driven or a device having the same function. The electric cylinder 400 is coupled to the calf support 300 at the front end of the rod under the femoral stimulation pole 200 and the rear end of the body of the electric cylinder 400 is rotatable axially to the body frame 100. Will be combined. The reason that the shaft is rotatably coupled is that, when the angle of the calf support 300 is adjusted to the rod that appears at the electric cylinder 400, the electric cylinder 400 must naturally rotate up and down. The electric cylinder 400 can be configured to be operated by an external remote control, so the user operates the remote control to adjust the angle of the calf support 300 to a desired angle.

Adjusting the angle of the backrest 140 can be achieved by adjusting the angle of the backrest rod 142. Adjust the angle by installing a ratchet gear on the part where the backrest rod 142 is connected to the femoral stimulation pole 200 or the body frame 100 or follow the arc line to the femoral stimulation pole 200 or the body frame 100 It is to form a pinhole and to adjust the angle by pinning the pinhole through the backrest rod (142). Of course, it can be formed so that the angle can be adjusted automatically. When the angle is adjusted automatically, a motor or gear is installed so that the angle can be adjusted automatically while the gear rotates according to the operation of the motor. It may be configured to be rotated by power to adjust the angle. This configuration allows the angle adjustment of the backrest 140 by the remote control.

Hereinafter, a process of exercising using the exercise device for improving hamstring flexibility according to the present invention described above will be described.

5 is an exemplary view of a user sitting on an upper body in an exercise device according to the present invention.

The user who wants to exercise sits on the femoral stimulation pole 200 like sitting on a chair in the body frame 100. In this state, the calf support 300 supports the calf, and the upper body is supported by the backrest 140.

After that, tighten the belt 150 to restrain the thigh. And as necessary, the angle of the calf support 300 and the backrest 140 is adjusted. In particular, when the calf support 300 and the backrest 140 are formed to be operated by a remote controller, the remote controller is operated to adjust the angle to a desired level. . This angle of the calf support 300 and the backrest 140 may be pre-adjusted before the user sits in the femoral stimulation 200.

In this state, the magnetic pole roller 220 is operated. In this process, the reciprocating distance of the magnetic pole roller 220 is set by a remote control to a required degree to operate. As a result, the stimulation roller 220 is stimulating the hamstring while reciprocating. When the front of the femoral stimulation pole 200 is formed higher than the back, the knee is positioned higher than the hip, and when the upper body is erected in this state, a certain force is applied in a direction to increase the hamstring, and it is in a tense state. When the 220 is reciprocated, the stimulation roller 220 stimulates the hamstring and releases tension.

6 is an exemplary view of a state in which the user tilts the upper body in the exercise device according to the present invention.

When the hamstring is relieved to some extent through the previous process, the upper body is bent. At this time, the spine is bent to an appropriate degree while applying strength to the waist so that the spine is not convex outward. Accordingly, the hamstring is increased, and in this state, the magnetic pole roller 220 continues to reciprocate and stimulate the hamstring. In this process, the hand 130 is grasped by the hand to keep the posture stable. In addition, by adjusting the angle of the calf support 300 with the electric cylinder 400, the degree of stretching the leg is adjusted. The user stretches the leg as much as he can withstand at his own discretion. While repeating the exercise, he or she freely adjusts the degree of bowing and the degree of stretching the leg according to the skill and flexibility of the user. In addition, by adjusting the angle of the backrest 140 to support the user's back portion to exercise.

In the above process, the calf zone 300 can be operated by using the remote controller, and the movement can be performed by adjusting the angle of the calf zone 300 step by step, and the user can check the current stage in the display window. You can exercise while checking the number of steps while operating the remote control directly.

According to the exercise process above, the user can exercise while freely setting the posture according to his or her athletic ability, and if the process is repeated, the hamstring is increased and the flexibility can be improved.
