Description

  For example, when the elementary school student holds the iron bar with both hands and hooks the back of the knee of one leg on the iron bar to perform forward or backward rotation, the skin on the back of the knee may be damaged. The present invention relates to a horizontal bar practice tool that reliably prevents occurrence.

  For example, when an elementary school student rotates forward or backward with a horizontal bar, it is common to hold the horizontal bar with both hands and keep the back of one leg's knees hooked on the horizontal bar.

None

  However, as before, when the forward and backward rotations were performed while maintaining the state where the back side of the knee of one leg was hooked on the iron bar, the skin on the back side of the knee hit the surface of the iron bar and the skin was pulled. When it was terrible, there was a situation where the skin on the back side of the knee peeled off.

  Therefore, the present invention was devised in view of the existing circumstances as described above. For example, an elementary school student holds a horizontal bar with both hands and hooks the back of one leg's knee to the horizontal bar to perform forward rotation and backward rotation. An object of the present invention is to provide a training tool for a horizontal bar that reliably prevents the occurrence of damage to the skin on the back side of the knee.

  In the present invention, a spiral cut is provided in a cylindrical elastic member having a predetermined length, and the elastic member is rotatably attached to the iron bar through the cut, and a wide adhesive tape is attached to the peripheral surface of the elastic member. By winding, the above-mentioned problems were solved.

  In the present invention, a spiral elastic cut is provided in a cylindrical elastic member having a predetermined length, and the elastic member is rotatably attached to the iron bar through the cut, and the elastic member is single or plural in the longitudinal direction of the elastic member. The above-mentioned problem was solved by pasting the adhesive tape and winding a wide adhesive tape around the peripheral surface of the elastic member.

  Furthermore, the elastic member solved the above-mentioned problem because the central portion bulges out.

  In the present invention, since a spiral cut is provided in a cylindrical elastic member having a predetermined length, anyone can easily attach the elastic member to the iron bar through this cut.

  Further, since the elastic member is cylindrical, the elastic member can be rotatably mounted on the iron bar.

  Further, since the wide adhesive tape is wound around the peripheral surface of the elastic member, the elastic member attached to the iron bar is sufficiently protected from the outside.

  Therefore, even when the training tool for the iron bar is exposed to the wind and rain, the state in which the elastic member attached to the iron bar can be smoothly rotated can be maintained for a long period of time.

  And, for example, when an elementary school student holds the iron bar with both hands and hooks the back side of the knee of one leg to the iron bar to rotate forward or backward, place the back side of the knee on the elastic member wrapped with adhesive tape Accordingly, the elastic member also rotates together with the forward rotation and the backward rotation.

  As a result, the skin on the back side of the knee of the person performing forward rotation or backward rotation does not contact the surface of the iron bar, and friction does not occur between the surface of the iron bar and the skin surface.

  Therefore, even when forward rotation and backward rotation are performed continuously or when rotational motion is performed at high speed, the skin on the back side of the knee is not pulled strongly, and the skin may be peeled off. Generation is surely prevented.

  Moreover, since the practice for a long time is possible by using the training tool for the iron bar, the technique of the iron bar can be dramatically improved.

  In addition, in the present invention, a spiral cut is provided in a cylindrical elastic member having a predetermined length, and the elastic member is rotatably attached to the iron bar through the cut, and the elastic member is singly or Since a plurality of adhesive tapes are pasted, the elastic member attached to the iron bar is prevented from unexpectedly falling off the iron bar and falling.

  In addition, since the wide adhesive tape is wrapped around the circumference of the elastic member including this adhesive tape, even when a heavy load is applied to the iron rod practice tool, the practice tool must maintain smooth rotation. Can do.

  Furthermore, even when a large load is applied to the training tool for the horizontal bar, the training tool is not damaged.

  Further, since the central portion of the elastic member is bulged, when the adhesive tape is wound around the peripheral surface of the elastic member, the central portion of the practice tool itself also bulges and the cushioning property is improved.

  Therefore, for example, when an elementary school student holds a horizontal bar with both hands and puts it on a training tool with a bulge on the back of one leg's knee, the feeling of pressure felt on the back of the knee can be felt. Can be reduced.

  Furthermore, even if a part of the inner peripheral surface of the elastic member rotates while contacting the surface of the iron rod and a part of the inner peripheral surface of the elastic member is scraped off, the central portion of the elastic member Since the bulge expands and has a predetermined thickness, it is still possible to maintain smooth rotation of the practice tool.

FIG.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated with reference to drawings.

  The present invention is a practice tool 1 for a steel bar P that is used by being mounted on the steel bar P.

  As shown in FIGS. 1A and 1B, the practice tool 1 for the iron bar P is composed of a cylindrical elastic member 2 having a predetermined length.

  The elastic member 2 is formed using, for example, urethane foam having a cushioning property of about 1 cm in thickness.

  Further, the elastic member 2 is provided with a spiral cut 3 along its own longitudinal direction. As shown in FIGS. 1A and 1B, the spiral cut 3 is provided so as to divide the elastic member 2 into about six sections in the elastic member 2 of about 30 centimeters.

  Then, the elastic member 2 is attached to the iron bar P as shown in FIGS.

  Specifically, at the one end portion of the elastic member 2, the notch 3 is widened with fingers to generate a slight gap.

  Next, as shown in FIG. 3, the gap at the extreme end along the notch 3 is directed to the iron bar P, the notch 3 is pushed forward while rotating the elastic member 2, and the elastic member 2 is covered on the iron bar P. The elastic member 2 is attached to the iron bar P (as if the iron bar P is introduced into the hole of the elastic member 2).

  When the entire elastic member 2 is attached to the iron bar P, the hand is released from the elastic member 2. Then, as shown in FIGS. 2A and 2B, the cut 3 is naturally closed by the return elastic force of the elastic member 2 itself.

  The inner diameter of the hole existing inside the elastic member 2 is substantially the same as the outer diameter of the iron bar P or slightly larger than the outer diameter of the iron bar P. Therefore, the elastic member 2 is attached to the iron bar P, and the entire elastic member 2 is maintained in a rotatable state with the cut portion 3 closed.

  Then, by winding the wide adhesive tape 4 around the peripheral surface of the elastic member 2 rotatably attached to the iron bar P, the practice tool 1 for the iron bar P according to the present invention is completed. FIG. As shown in FIG. 5B, a plurality of adhesive tapes 5 are pasted in the longitudinal direction of the elastic member 2, and as shown in FIGS. 5A and 5B, the entire peripheral surface of the elastic member 1 including the adhesive tape 5 is attached. When the wide adhesive tape 4 is wound, it becomes more preferable.

  As shown in FIGS. 4A and 4B, the adhesive tape 5 is attached in the longitudinal direction of the elastic member 2 so that the two adhesive tapes 5 face each other, and the cut 3 of the elastic member 2 is closed. Is maintained.

  This adhesive tape 5 is attached so as to straddle the thick surface, the peripheral surface, and other thick surfaces of the elastic member 2.

  Note that only one adhesive tape 5 may be attached in the longitudinal direction of the elastic member 2, or three or more adhesive tapes 5 may be attached.

  As shown in FIGS. 5 (a) and 5 (b), the wide adhesive tape 4 is wound around the entire peripheral surface of the elastic member 2 so that a part of the adhesive tape 4 overlaps. It becomes the durable thing as the practice tool 1 of the horizontal bar P.

  Further, when the wide adhesive tape 4 is wound several times from one end to the other end on the peripheral surface of the elastic member 2 and the adhesive tape 4 is laminated, the practice tool 1 of the iron bar P becomes more durable. Become.

  In addition, as shown in FIG. 6, in the elastic member 1 of about 30 centimeters, a spiral cut 3 may be provided so as to divide the elastic member 2 into about four sections.

  Moreover, as shown to Fig.7 (a), about the elastic member 2, it forms so that a center part may swell and you may provide this elastic member 2 with the helical cut | notch 3. FIG.

  Then, as shown in FIG. 7B, the bulging elastic member 2 is attached to the iron bar P, and two adhesive tapes 5 are arranged in the longitudinal direction of the elastic member 2 as shown in FIG. 7C. Then, the wide adhesive tape 4 is wound around the entire peripheral surface of the elastic member 2 including the adhesive tape 5 to complete the practice tool 1 for the iron bar P.

  In addition, various colors may be applied to the wide adhesive tape 4 or a pattern such as a character may be drawn so that children who practice the iron bar P can enjoy it.

  When using the training tool 1 of the iron bar P according to the present invention, as shown in FIG. 8, for example, an elementary school student holds the iron bar P with both hands and hooks the back side of the knee of one leg to the iron bar P to rotate forward or backward. When performing, the back side of the knee is placed on the elastic member 2 around which the wide adhesive tape 4 is wound.

  When the elementary school student rotates forward or backward in this state, the elastic member 2 attached to the iron bar P also rotates together.

  As a result, even if the elementary school student continuously performs forward rotation and backward rotation on the horizontal bar P, or when the rotary motion is performed at high speed, the back side of the knee does not hurt, and the horizontal bar P can be practiced happily. It can be done.

  The iron bar practice tool according to the present invention can be used, for example, when the back side of the knee of one leg is hooked on the iron bar to perform forward rotation or backward rotation. It can be widely used to practice various iron bars, such as putting a stomach on a practice tool when performing a forward run.
