Description

Technical Field

[0001] The present invention relates to a loop rope fixing mechanism, and more particularly, to a loop rope fixing mechanism including a stopper and a method for forming the loop rope fixing mechanism, wherein the stopper fixes the loop rope in a length-adjustable manner when the loop rope is wound around a support body, and the loop rope is formed by bending and arranging ropes and forming a loop at one end. Background Art

[0002] Figure 1 The figure is a diagram showing a known pull-up handle using a loop rope. The pull-up handle is an auxiliary mechanism used when performing exercises such as pull-ups. Figure 2 The figure shows a configuration in which the pull-up handle is fixed to the straight bar.

[0003] The pull-up exercise is a sport for improving the upper limb muscle strength of the user. Usually, the pull-up exercise is performed by holding a straight bar fixed at a given height and pulling the body upward.

[0004] When using a straight bar, you can use an overhand grip or an underhand grip. An overhand grip is when the back of the user's hand faces the user, and an underhand grip is when the user's palm faces the user. When doing pull-ups, if you change the grip angle, the type and position of the muscles stimulated will change accordingly. Although this can improve the exercise effect, there are also limitations to using a straight bar. The pull-up handle helps you do pull-ups in a variety of grip positions.

[0005] In addition, the straight bar is generally provided in a fixed form at a predetermined height so as to support the body weight. Therefore, when the position of the straight bar does not match the height of the user, it is difficult to perform pull-ups.

[0006] As described above, in order to help perform exercises that match the user's height and muscle strength status and to help perform various exercises that can strengthen muscle strength, the following are used: Figure 1 Pull-up handle shown.

[0007] Reference Figure 1 The pull-up handle 2 includes: a loop rope 3, which is formed by arranging ropes S at the ends to form loops; and a handle 8, which fixes the two ends of the loop rope 3 for grasping.

[0008] The loop rope 3 means a rope (cord, rope, string, etc.) extending in the length direction, with the middle portion bent and arranged to form a loop in the middle portion. In this specification, the rope forming the loop is referred to as the loop rope 3, the portion located at one end of the loop rope 3 and forming the loop is referred to as the loop portion 4, and the ends of the two branches of the loop rope located on the opposite side of the loop portion 4 are referred to as rope ends 5, 6.

[0009] Reference Figure 2 , the sequence of fixing the pull-up handle 2 to the straight bar 1 is as follows.

[0010] First, the loop portion 4 of the loop rope 3 is passed over the straight pole 1 , so that the loop rope 3 is wound around the straight pole 1 .

[0011] Then, the handle 8 is passed through the rings 4 from below the straight rod 1 and moved to the opposite side, and then the handle 8 is pulled to be tightened, so that the pull-up handle 2 is fixed to the straight rod 1 .

[0012] The form in which the loop rope 3 is wound around the straight rod 1 and fixed is called a Lark's Head KNOT or a Tag KNOT.

[0013] The name of the tag knot comes from the fact that item tags are mainly fixed in a knotted shape as shown above.

[0014] In order to perform pull-up exercises, two pull-up handles 2 are fixed to the straight bar 1. The user holds the handles 8 of the pull-up handles 2 by hand to perform exercises such as pull-ups.

[0015] The pull-up handle is not only used for pull-ups, but also for various exercises. For example, the pull-up handle can be fixed to the ring of the counterweight to perform the exercise of lifting the counterweight. In addition, the upper body can be lifted by holding the pull-up handle with both hands while the body is tilted and supported with both feet on the ground.

[0016] As described above, the pull-up handle is not limited to the pull-up exercise, and the ring rope can also be fixed to an object such as a straight bar or a counterweight to perform various exercises, thereby exerting the function of bearing body weight.

[0017] This known method of utilizing a tag knot is to hang a pull-up handle having a known loop rope on a support body for fixing. Although this is the most common method, the loop rope length cannot be adjusted, and thus the handle height cannot be adjusted.

[0018] Therefore, when the pull-up handle is mounted on a support body such as a straight bar or a ring at a fixed height for exercise, the loop rope needs to be replaced according to the height of the user. In addition, if the pull-up handle is to be removed from the support body, the knotted and fastened loop needs to be untied and the handle needs to be removed, which is very inconvenient. Summary of the invention

[0037] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0038] The present invention can be subjected to various changes and can have various forms, and the embodiments will be described in detail in the text. However, this is not to limit the present invention to a specific disclosed form, and it should be understood that it includes all changes, equivalents and substitutes included in the thought and technical scope of the present invention. When describing each figure, similar reference numerals are used for similar constituent elements.

[0039] The terms are used only to distinguish one component from another component. The terms used in this application are used only to illustrate specific embodiments and are not intended to limit the present invention. Unless the context clearly indicates otherwise, a singular expression includes a plural expression.

[0040] Figure 3 and Figure 4 The following are three-dimensional views of the stopper of the loop rope fixing mechanism according to the embodiment of the present invention as viewed from the front and back directions. Figure 5 This is a diagram showing a state in which the first rope extension part and the second rope extension part in the loop rope fixing mechanism of the embodiment of the present invention are assembled to the stopper. Figure 6 and Figure 7 The figure is used to explain the state in which the loop portion of the loop rope fixing mechanism according to the embodiment of the present invention is knotted and fixed with the first rope extension portion and the second rope extension portion through the stopper in a state in which the loop rope is wound around the straight rod.

[0041] The loop rope fixing mechanism 10 of the present invention comprises a stopper 20 for fixing the loop rope, and the stopper 20 fixes the loop rope 11 in a manner in which the length thereof can be adjusted.

[0042] The loop rope 11 bends and arranges the middle portion of the rope S extending along the length direction to form a loop portion 12. The rope S extending as two branches of the loop portion 12 is called the first rope extension portion 15 and the second rope extension portion 17. The ends of the first rope extension portion 15 and the second rope extension portion 17 opposite to the loop portion 12 are called the first rope end portion 14 and the second rope end portion 16.

[0043] Reference Figure 3 and Figure 4 The stopper 20 for fixing the loop rope of the embodiment of the present invention includes a front plate 21 having a through hole formed therein. In addition, it also includes two side plates 32 and 34 extending to the back side of the front plate 21 and intersecting the front plate 21.

[0044] The front plate 21 includes two through-hole rows 22 and 26, and each through-hole row 22 and 26 includes two through-holes 23, 24, 27, and 28. The through-holes 23, 24, 27, and 28 may be formed as circular holes.

[0045] The through-hole rows 22 and 26 of the front plate 21 form passages through which the first and second rope extending portions 15 and 17 pass.

[0046] The side walls 32 and 34 extend crosswise relative to the front panel 21 toward the back side of the front panel 21. The side walls 32 and 34 are used to maintain the ring portion 12 that forms a knot with the first rope extension portion 15 and the second rope extension portion 17 on the back side of the front panel 21. As a result, the ring portion 12 is kept in contact with the first rope extension portion 15 and the second rope extension portion 17 without being unfolded. When tension is applied in this contact state, the rope extension portion and the ring portion are fastened to each other by friction. This fastening causes a state such as jamming, and a knot that resists the pulling force on the rope end side is formed by the connection between the ring portion and each rope extension portion.

[0047] Reference Figure 5 , explaining the assembly relationship between the ring rope and the limiter in the ring rope fixing mechanism.

[0048] The first rope extension portion 15 and the second rope extension portion 17 are branched from both sides of the ring portion 12 and extend toward the first rope end portion 14 and the second rope end portion 16 , respectively.

[0049] The first rope extension portion 15 extends through the first through-hole row 22 of the stopper 20. The first rope extension portion 15 extending toward the first rope end portion 14 extends to the back surface B of the front panel 21, is inserted into the upper through-hole 23 in the first through-hole row 22, and is led out to the front surface F of the front panel 21. Furthermore, the first rope extension portion 15 is inserted into the lower through-hole 24 at the front surface F, and is led out to the back surface B of the front panel 21 and extends.

[0050] The second rope extension portion 17 extends through the second through-hole row 26. The second rope extension portion 17 extending toward the second rope end portion 16 extends to the back surface B of the front panel 21, is inserted into the upper through-hole 27 in the second through-hole row 26, is led out to the front surface F of the front panel 21, and is then inserted into the lower through-hole 28, thereby extending downward toward the back surface B of the front panel 21.

[0051] The position of the stopper 20 can be adjusted by moving the stopper 20 along the loop rope 11. In the loop rope fixing mechanism 10, the loop portion 12 of the loop rope 11 is fixed to the stopper 20, so adjusting the position of the stopper 20 relative to the loop rope 11 is equivalent to adjusting the length of the loop rope 11 wound on the support body.

[0052] Reference Figure 6 and Figure 7 , explaining the form of forming a knot and fixing the position of the loop rope by using the limiter in the loop rope fixing mechanism as a medium.

[0053] Reference Figure 6After the ring rope 11 is passed over a support body 100 such as a straight pole and changed in direction in a suspended state, the ring portion 12 is pulled to the position of the limiter 20, and then the ring portion 12 is passed over the back side B of the limiter 20 and the ring rope 11 is pulled.

[0054] Reference Figure 7 As shown in the enlarged portion A, the ring portion 12 is located between the back surface B of the stopper 20 and the first rope extension portion 15 and the second rope extension portion 17 that are drawn out through the lower through holes 24 and 28 and extend downward. At this time, the downward tension acting on the first rope extension portion 15 and the second rope extension portion 17 and the upward tension acting on the ring portion 12 act together, and the ring portion 12 is tightened to fix it. In this specification, as described above, fixing the rope through the stopper 20 is called forming a knot. Figure 7 The knot shown is formed similarly to the tag knot.

[0055] The two side walls 32 and 34 are arranged in such a manner that when tension acts on the loop rope 11, the first rope extension part 15 and the second rope extension part 17 are in a tightened state with the loop part 12. Thus, the loop part 12 is not spread out due to the two side walls 32 and 34, and extends upward along the back surface B of the stopper 20 while pressing the first rope extension part 15 and the second rope extension part 17.

[0056] Reference Figure 7 It can be seen that the ropes on both sides of the ring 12 are pressed toward the side walls 32 and 34 by the ropes passing through the through holes 23, 24, 27, and 28. If there were no side walls 32 and 34, the ring 12 would be unfolded after contacting the first rope extension part 15 and the second rope extension part 17 passing through the lower through holes 24 and 28 at the lower side of the lower through holes 24 and 28. At this time, the fixing force of the knot would be weakened. However, with the help of the side walls 32 and 34, when the ring 12 contacts the first rope extension part 15 and the second rope extension part 17 and extends from the back side B of the stopper 20, the knot is strongly fixed while jamming between the ropes.

[0057] Figure 8 It is used to explain the adjustment of the length of the loop rope in the loop rope fixing mechanism of the present invention. In the loop rope fixing mechanism, as the position of the stopper 20 is adjusted, the length of the loop rope 11 between the support body 100 and the stopper 20 changes. The loop rope 11 overlaps between the support body 100 and the stopper 20, so if the position of the stopper is changed, the position of the rope end relative to the support body 100 is adjusted. The position of the rope end relative to the support body 100 corresponds to the length of the loop rope fixed to the support body, so the length of the loop rope can be adjusted.

[0058] Refer again Figure 6 and Figure 7 , Figure 6 and Figure 7 The embodiment of the loop rope fixing mechanism according to the embodiment of the present invention is shown as an embodiment in which the loop rope fixing mechanism is implemented by a pull-up handle.

[0059] like Figure 6 and Figure 7 As shown, the first rope end 14 and the second rope end 16 are fixed to the rod 30. As the position of the limiter 20 changes, the fixing position of the ring 12 changes, thereby changing the position of the rod 30 relative to the support body 100, that is, changing the height relative to the ground.

[0060] Fig. 9 The embodiment of the loop rope fixing mechanism according to the embodiment of the present invention is shown as an embodiment implemented in the form of a swing.

[0061] Reference Fig. 9 , two loop rope fixing mechanisms 10a and 10b are provided, and the loop rope fixing mechanisms 10a and 10b are respectively combined on the side of the seat plate 40. The rope ends on both sides of one loop rope fixing mechanism 10a are combined on one side of the seat plate 40, and the rope ends on both sides of the other loop rope fixing mechanism 10b are combined on the other side of the seat plate 40.

[0062] The height of the seat plate 40 relative to the support body 100 is adjusted in such a manner that the overlapping length of the loop rope 11 is adjusted in each of the loop rope fixing mechanisms 10 a and 10 b. Fig. 9 As shown in the figure, two swings are arranged at different heights. As described above, if a loop rope fixing mechanism is used, the object supported by the loop rope fixing mechanism can be adjusted relative to the support body. Fig. 9 The height of the seat plate can be adjusted.

[0063] As another embodiment of the present invention, in the loop rope fixing mechanism, the ends of the ropes on both sides can be connected to each other. This embodiment is another example of using the loop rope fixing mechanism to implement the pull-up auxiliary mechanism. The rope has sufficient elasticity. The user steps on the loop rope at the lower part and can perform pull-ups with the help of the elastic rope. The user can adjust the length of the loop rope according to the straight bar and height.

[0064] The present invention is described in detail above through representative embodiments, but the scope of the present invention is not limited to the description and description of the embodiments described above. The scope of the present invention will not be limited by obvious changes or substitutions in the technical field to which the present invention belongs. The scope of the present invention is determined by the claims described below and the equivalents of the claims.
