JP5881126B2 - Horizontal bar exercise tool - Google Patents

Description

  The present invention relates to a horizontal bar exerciser for practicing “reverse climbing”, which is a technique of a horizontal bar in instrument movement.

  The reverse rise with a low iron bar is an exercise that almost everyone experiences in compulsory education in Japan. However, because it is possible or not, it is clearly visible, and for those who cannot, there are cases where people are not good at planting a horizontal bar, and eventually exercise.

As shown in FIGS. 4A to 4H, this reverse rise is referred to as “upper movement movement of the lower body” (A ₁ → A ₂ ) and “backward rotation movement of the upper body” (B ₁ → B ₂ ). It consists of two movement components. The lower body's upward movement motion is a motion of kicking the ground with a foot and swinging the foot upward. In addition, the upper body's backward rotation movement is an exercise that rotates the upper body backward while bringing the waist close to the horizontal bar. In the process, the shoulder angle (the arm is lowered and the state along the trunk is 0 degrees). The state is 180 degrees). These two elements work closely with each other, and if you do not move the lower and upper body at the same time, you cannot succeed in going up. Typical examples of failing to move up are when the legs are raised, the shoulders open and the torso moves away from the iron bar, or the upper body cannot be rotated backward from fear.

  Conventionally, there are those shown in Patent Document 1 and Patent Document 2 as reverse-up practice tools. The practice tool of Patent Document 1 is to install a curved legrest in front of the iron bar, and is used so that the practitioner runs up with his / her foot while holding the iron bar. The practice with this exercise tool is to improve the swing of the foot and take off the foot, and to make the waist closer to the horizontal bar, to reduce the shoulder angle, to compensate for the kick of the foot, muscle effort of the upper body Can be reduced. Moreover, the training tool of patent document 2 supports a practitioner's waist | hip | lumbar and back with a belt, and an assistant pulls the string connected with the belt, and rotates a practitioner's trunk | drum back. . Practice using this exercise tool is to forcibly rotate the body and automatically reduce the shoulder angle.

  However, the practice using the invention of Patent Document 1 focuses on the upper body's upward movement movement, and there are not many elements of the upper body's backward rotation movement. In many cases, it was not possible. In addition, the practice using the invention of Patent Document 2 forces an extraordinary posture change in which the head is dropped backward while being suspended, so the person who feels fear and hesitates to fall back There are also many. The focus is on the rotational movement of the upper body, and there are not many elements of the lower body's upward movement. For practitioners with weak foot swings, the legs do not rise upward and the lower body falls. It is sometimes seen that the posture is warped. Furthermore, since an assistant is required, there are problems in that it depends on the skill of the assistant and that one assistant must be attached to one implementer.

  The present invention has been made in view of the above circumstances, and provides a horizontal bar exerciser that can simultaneously learn the upward movement of the lower body and the backward rotation of the upper body, which are necessary for reverse climbing, and does not require an assistant. The purpose is to do.

  The present invention includes a first arm part, a second arm part, a body support part, and a foot support part, both of the first arm part and the second arm part being orthogonal to the iron rod, Are connected at an angle of 90 degrees or more and 180 degrees or less around the longitudinal axis of the iron bar, and the coupling part is attached to the iron bar so as to be rotatable around the longitudinal axis of the iron bar. It is provided at the tip of one arm and extends in parallel with the iron rod, and the foot support is provided at the tip of the second arm and extends in parallel with the iron rod. It is characterized by having a space as a body insertion portion and a space between the iron bar and the foot support portion as a foot insertion portion.

  According to the present invention, the torso is inserted into the body insertion portion, one foot is hung on the foot support portion, the back is placed on the body support portion, the ground is kicked with the other foot, or the foot support portion is placed on one foot. The whole of the horizontal bar exercise tool rotates around the longitudinal axis of the horizontal bar, either by stepping on and swinging up the other leg or both, and accordingly, the foot hung on the foot support is raised upward. The torso that moves and hits the body support part rotates backward. Accordingly, the upward movement movement of the lower body and the backward rotation movement of the upper body are simultaneously induced, and a correct sensation of reverse rise can be learned. And no assistant is needed at that time.

It is a perspective view of the horizontal bar practice tool of the present invention. It is a perspective view which shows the use condition of a horizontal bar training tool. (A)-(h) is a continuous photograph which shows the Example of the practice of going up using the horizontal bar practice tool. (A)-(h) is a continuous photograph which shows the example of a reverse rise.

  The specific structure of the horizontal bar practice tool of the present invention will be described with reference to the drawings. In the following, front and rear and left and right indicate front and rear and right and left directions as viewed from the practitioner (the left and right direction is the longitudinal direction of the iron bar B). This iron bar training tool is used by attaching to a low iron bar about the height of the chest of the practitioner. As shown in FIG. 1, the first arm is formed by integrally bending an iron round pipe. A part 1, a second arm part 2, a body support part 3, a foot support part 4, a first auxiliary arm part 7 and a second auxiliary arm part 8 are provided. More specifically, the first arm portion 1 and the second arm portion 2 are orthogonal to the iron bar B, and the base ends are at a predetermined angle θ (135 degrees in this embodiment) around the longitudinal axis of the iron bar B. They are connected (that is, one round pipe is bent so that one side is a first arm portion 1 and the other side is a second arm portion 2). Then, the inferior angle (smaller corner) side of the connecting portion C (bending portion) of the first arm portion 1 and the second arm portion 2 is brought into contact with the iron bar B, taping T is applied, and the length of the iron bar B It is attached so as to be rotatable around a direction axis. The body support portion 3 is formed by bending the tip of the first arm portion 1 at a right angle and extends in the right direction (direction parallel to the iron bar B). Further, the first auxiliary arm portion 7 is formed by bending the tip of the body support portion 3 at a right angle, extends perpendicularly to the iron rod B and toward the iron rod B, and has a first mounting portion 71 at the tip. It is provided. The first mounting portion 71 is a resin-made round pipe provided with a cutout portion 72 along the central axis direction so as to have a substantially C-shaped cross section, and the inner diameter is substantially equal to the outer diameter of the iron bar B. Although the width of the notch 72 is narrower than the diameter of the iron bar B, it can be fitted into the iron bar B by elastic deformation, so that the tip of the first auxiliary arm part 7 is in the longitudinal direction of the iron bar B with respect to the iron bar B. Attached so as to be rotatable around an axis. On the other hand, the foot support portion 4 is formed by bending the tip of the second arm portion 2 at a right angle, and extends in the right direction (direction parallel to the iron bar B). However, the foot support part 4 is shorter than the body support part 3. Further, the second auxiliary arm portion 8 is formed by bending the tip of the foot support portion 4 at a right angle, extends perpendicularly to the iron bar B and toward the iron rod B, and has a second mounting portion 81 at the tip. It is provided. The second mounting portion 81 is provided with a notch portion 82 similar to that provided in the first mounting portion 71, whereby the tip of the second auxiliary arm portion 8 is longer than the length of the iron bar B with respect to the iron bar B. Attached so as to be rotatable around a direction axis. The attachment position of the second auxiliary arm portion 8 with respect to the iron bar B is an intermediate position between the attachment position of the connecting portion C and the attachment position of the first auxiliary arm portion 7 (just the middle position between both). And the inside of the substantially rectangular frame formed by the iron bar B, the body support part 3, the first arm part 1, and the first auxiliary arm part 7 is the body insertion part 5, An inner side of a substantially rectangular frame formed by the foot support portion 4, the second arm portion 2, and the second auxiliary arm portion 8 is a foot insertion portion 6. Further, a cylindrical roll body 9 is provided at a position between the body support portion 3 and the connecting portion C of the iron bar B and the first auxiliary arm portion 7. However, the roll body 9 of the iron bar B is provided so as to cover the second mounting portion 81. The roll body 9 is rotatable with respect to the body support portion 3 or the iron bar B (the roll body 9 of the iron bar B rotates together with the iron bar training tool), and the surface is formed of a soft material such as sponge or cloth. It is desirable.

  As shown in FIG. 2, the practitioner P inserts the torso into the body insertion part 5 and the left foot into the foot insertion part 6 to use the horizontal bar training tool configured as described above. Is hung on the foot support 4. The left hand grasps a portion between the connecting portion C of the iron bar B and the roll body 9, and the right hand grasps a portion between the first auxiliary arm portion 7 of the iron bar B and the roll body 9. Here, the length of the body support portion 3 is long enough to accommodate the body of the practitioner P in the body insertion portion 5, and the lengths of the first arm portion 1 and the first auxiliary arm portion 7 are When the person P bends the elbow 90 degrees and grips the iron bar B, the length of the back (between the scapula and the buttocks) is in contact with the body support part 3, that is, approximately the same as the forearm of the person P It is length. Moreover, since the foot support part 4 is located on the left side of the body support part 3, it is easy for the practitioner P to put on the left foot, and the length is long enough to fit one foot in the foot insertion part 6. The lengths of the second arm portion 2 and the second auxiliary arm portion 8 are such that the knee of the left foot of the practitioner P bends lightly, that is, slightly shorter than the paw of the practitioner. Here, it is assumed that the person P's dominant leg is the right leg, and when the dominant leg is the left leg, the right leg is used by using a horizontal bar training tool having a shape reversed to that of the present embodiment. It is desirable to insert into the foot insertion part 6.

  Next, reverse climbing exercises performed using this horizontal bar training tool will be described. First, as shown in FIG. 1 and FIG. 1, the iron rod training tool is attached to the iron bar B, and the practitioner P inserts the torso into the body insertion portion 5 and the foot support portion 4 into the left foot as shown in FIG. Multiply. From this state (Fig. 3 (a)), when the practitioner P kicks the ground with his right foot (dominant foot) and raises both feet, the left foot is hung on the foot support part 4, so the horizontal bar exerciser is also together While starting to rotate, since the back is applied to the body support portion 3, the upper body rotates backward (FIGS. 3B and 3C). At this time, since the upper body is always supported by the body support portion 3, there is no fear of fear. The body of the practitioner P and the horizontal bar training tool continue to rotate together (Figs. 3 (d) to (g)), and by one rotation (Fig. 3 (h)), a series of reverse movements. Can be experienced. In addition, in the process of rotation, the front and back surfaces of the upper body come into contact with the roll body 9 that is pivotally attached to the iron bar B and the body support portion 3, so that smooth rotation is possible and the impact of the contact is absorbed. Is done. In this practice, the foot is supported by the foot support part 4 and the torso is supported by the body support part 3, so that the lower body moves upward and the upper body rotates backward by the momentum of kicking the ground and raising the foot. Is done. And since it rotates with the posture of the body with respect to the iron bar B maintained, the shoulder angle is not opened and the body does not leave the iron bar B. Therefore, it is possible to easily experience and learn the kinesthetic sensation necessary for going up. In addition, there is no need for an assistant, and one person can practice effectively.

  Next, the result of the experiment for confirming the effect of the horizontal bar training tool will be described. Here, a guidance experiment was conducted for five female college students who could not go upside down for about 20 minutes once and once a week for 4 weeks. As a result, 4 out of 5 people were able to succeed in going up.

  Three of the five subjects did not rotate their upper body well, but by experiencing the backward rotation while raising their legs with this exercise tool, they can develop the kinesthetic sense of backward rotation without fear. I was able to. In addition, by performing backward rotation in a reverse climbing movement, you can feel the cooperative action unique to reverse climbing, such as easy to rotate backward by raising your legs, and easy to raise your legs by defeating the upper body. It was thought that this led to a smoother acquisition of backward rotation. One of them did not succeed within the period, but a movement change approaching success was seen.

  In the other, the upper half of the upper body was rotated excessively, and the lower half was not rotating. However, with the practice tool, the swinging of the foot and the backward rotation were finally performed in conjunction with each other. This exercise tool automatically raises the lower body when the upper body is knocked down, so practicing many times is thought to have led to the establishment of the correct form of reverse rise.

  The last person was good at linking the two movements of the lower and upper body, but did not know the sense of pulling the arm while rotating and going up to the horizontal bar. However, just by practicing several times with the practice tool, I was able to grasp the tips that rotate and succeed. Since this exercise tool can confirm the place where force is applied while rotating, it is considered that this exercise tool was very effective for this subject.

  Based on the above results, this exercise tool “can't rotate the upper body backwards well”, “can't swing the legs well”, “cannot do the cooperative action of the upper and lower body specific to reverse climbing” "I don't know how to pull the arm up and get up to the horizontal bar." By practicing with this practice tool, we were able to grasp the overall structure of the kinematics of upside-down movements and grasped the knack of exercise. As a general tendency, the ability to achieve reverse climbing is strongly defined by the ability of the sensory system more than that of the muscular strength system, so this exercise tool that can grasp the sense of the entire reverse climbing movement is very effective. In addition, this exercise tool is very effective in that subjects with different exercise tasks can solve the problem with one exercise tool without changing the practice place and practice method.

  In addition, this iron bar training tool should be of a size that matches the physique of the practitioner, and as described above, the first arm and the first auxiliary arm are approximately the same length as the practitioner's forearm. The second arm part and the second auxiliary arm part preferably have a length slightly shorter than the practitioner's foot. Therefore, a plurality of sizes may be prepared in advance, but the first arm portion, the first auxiliary arm portion, the second arm portion, and the second auxiliary arm portion may have a double tube structure. And may be telescopic. Further, the first arm portion and the second arm portion may be connected to each other so that the angle is variable in a range of 90 degrees to 180 degrees, and the first arm section and the second arm section may be fixed at an angle that is easy for the practitioner to use. Furthermore, if the first arm part and the second arm part are connected in an angle variable range from 90 degrees to 270 degrees, when the angle is 180 degrees to 270 degrees, the body support part The left and right positions of the foot support part with respect to the reverse will be reversed, and the first arm part and the second arm part can be freely set in the range of 90 to 180 degrees, so practice regardless of the practitioner's dominant foot Can do.

  In addition to the method of kicking up the ground as described above, there is a method of lifting the lower body without kicking the ground from a state where the foot is on the ground or a state where it is hung on a horizontal bar, in addition to the method of kicking the ground and swinging up the foot as described above. When practicing this method, it is only necessary to step on the foot support portion with one foot and then swing up the other foot, and this method may be combined with a method of kicking the ground.

  In addition to the above-described reverse climbing exercise, the horizontal bar exerciser can also be used for rear support rotation (so-called “rearward rotation”). The rear support rotation is a state in which the body is inserted into the body insertion portion from the beginning, and one foot is inserted into the foot support portion from the beginning. If the other leg is swung up and rotated while the hang-up is applied, the horizontal bar training tool will also rotate once, and the hip will always be assisted to keep it away from the horizontal bar.

  Furthermore, according to this iron bar practice tool, the body can be rotated backward by simply tilting the upper body backward and placing the weight on the body support portion without kicking the ground or raising the foot. This is because the first arm portion and the second arm portion are connected at a predetermined angle (90 degrees or more and 180 degrees or less) around the longitudinal axis of the iron bar.

  The present invention is not limited to the above embodiment. The shape of each part can be changed as appropriate within the range of requirements. For example, it does not have the first auxiliary arm part or the second auxiliary arm part, but is cantilevered only by the first arm part or the second arm part. It may be a thing. Moreover, the attachment part and the attachment method with respect to the iron rod of a 1st attachment part and a 2nd attachment part may be what as long as it is rotatable. The material may be any material as long as it can withstand the load and impact during use, and other metals such as aluminum, and resins such as vinyl chloride and acrylic may be used.
