Description

Technical Field

[0001] The present invention relates to a hanging wrist roller, in which a grip rod is rotated by a user while being suspended in the air to perform a wrist-rolling motion. Background Art

[0002] The hanging wrist roller is known as one of the exercise apparatuses for exercising forearm muscles.

[0003] Figure 1 Shown is a hanging wrist roller of Korean Patent Publication No. 10-2018-0010415, which was invented and applied for publication by the inventor of the present invention.

[0004] Refer to Figure 1 , a conventional hanging wrist roller includes: a grip rod 1, with a weight 3 suspended by a rope; and a hanging member 5, which suspends the grip rod 1 on an upper support frame (not shown) using a strip 8a or a rope 8b. The hanging member 5 includes: an upper member 5a, made of metal, for fixing the strip 8a or the rope 8b; and both lower side members 5b, having hooks 6 for hooking the grip rod 1. The hook 6 of the lower member 5b is hooked on the hook groove 2 of the grip rod 1.

[0005] The strip 8a can be directly fixed to the hanging member 5, and the rope 8b can be coupled to the hanging member 5 through a hook 9.

[0006] The hanging wrist roller refers to an apparatus that, while the grip rod is suspended in the air, holds the grip rod from both sides in a posture of stretching both arms forward, and rotates the grip rod alternately with one hand to perform a wrist-rolling motion. The hanging wrist roller is beneficial for balancing the exercise of the forearm muscles of both arms.

[0007] However, the conventional hanging wrist roller has the following problems.

[0008] First, it has the disadvantage of being difficult to adjust the height of the grip rod. Generally, the hanging wrist roller is effective when exercising in a posture of stretching both arms side by side. However, the conventional hanging wrist roller is fixed at the initially set height, so there is a disadvantage that the exerciser cannot adjust the height of the grip rod according to his / her own body. Second, in order to facilitate the insertion of the grip rod, the hook of the hanging member is in a partially open form, so attention needs to be paid to the detachment of the grip rod during exercise. Third, as the grip rod rotates, friction is generated between the hook of the metal hanging member and the grip rod, resulting in hindering the balance of the motion, and generating noise and wear. Summary of the Invention

[0009] Problems to be Solved by the Invention

[0010] An object of the present invention is to provide a hanging wrist roller in which the height of a grip rod can be easily adjusted, and the grip rod is suspended in the air using a rope.

[0026] Hereinafter, with reference to the accompanying drawings, the specific content for implementing the present invention will be described. And, in the description of the present invention, if the relevant well-known functions are obvious to those skilled in the art and it is judged that they may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

[0027] Figure 2 It is the front view of the hanging wrist exerciser of the embodiment of the present invention, Figure 3 It is the partial enlarged perspective view of the hanging wrist exerciser of the present invention, Figure 3 a and b of which show opposite directions.

[0028] Refer to Figure 2 and Figure 3 , the hanging wrist exerciser of the embodiment of the present invention includes: a grip 100; a height adjustment plate 200; an upper rope 300 for hanging the grip 100 on a support frame 10 arranged on the upper side; and a lower rope 400 for hanging a weight 500 on the grip 100.

[0029] The grip 100 includes: a central portion 110; left and right handles 120 respectively arranged on both sides of the central portion 110; and a sheave 150 located between the central portion 110 and the left and right handles 120.

[0030] The central portion 110 is a part located in the middle of the grip 100 and for the lower rope 400 to wind around, and can be formed in a cylindrical shape.

[0031] On both sides of the central portion 110, lower rope fixing portions 112 are formed for respectively fixing both end portions of the lower rope 400.

[0032] The handle 120 is the part where the user holds the grip 100, and is arranged on both sides of the central portion 110. The handle 120 is formed to rotate together with the central portion 110. The left and right handles 120 can be integrally formed with or combined with the central portion 110.

[0033] On both sides of the central part 110 and between the left and right side handles 120, there is a sheave 150. The sheave 150 includes a groove 152 formed along the circumferential direction of the grip rod 100. The sheave 150 is a part for supporting a loop 350 formed at the lower part of the upper rope 300, and the loop part 350 bypasses the groove 152 of the sheave 150.

[0034] The upper rope 300 connects the upper support frame 10 and the grip rod 100, and functions to suspend the grip rod 100 in the air. The support frame 10 is shown as a rod shape in Figure 2 but is not limited thereto and can have various shapes. For example, it can be a hook suspended on a structure capable of fixing a rope. When the support frame 10 is in a rod shape, it can be combined by forming a knot.

[0035] The upper rope 300 includes a first upper rope part 310 and a second upper rope part 320 that branch from the support frame 10 and extend downward. The upper rope 300 can be formed as a single rope. A knot 302 is formed in the central part of the upper rope 300 and connected to the support frame 10, and both side parts form the first upper rope part 310 and the second upper rope part 320 and extend downward.

[0036] The loop part 350 is formed at the lower parts on both sides of the upper rope 300. The two side parts of the upper rope 300, namely the first upper rope part 310 and the second upper rope part 320, extend downward through the height adjustment plate 200, pass through the groove 152 of the sheave 150 and then turn, extend upward and are fixed on the height adjustment plate 200. In this way, the loop part 350 is formed.

[0037] The lower rope 400 functions to suspend the weight 500 on the grip rod 100. At the lower end of the lower rope 400, there are included a first lower rope part 410 and a second lower rope part 420 that are connected to the weight 500 and branch and extend upward.

[0038] The lower rope 400 can be formed as a single rope. The lower rope 400 passes through a hook formed at the upper end of the weight 500 and extends upward, and the branched and extended one side and the other side parts become the first lower rope part 410 and the second lower rope part 420.

[0039] The upper ends on both sides of the lower rope 400 are fixed on the rope fixing parts 112 formed on both sides of the central part 110 of the grip rod 100. The rope fixing parts 112 can be formed as holes located on both sides of the central part 110. The rope fixing parts will be described below.

[0040] When the upper ends of the first lower rope part 410 and the second lower rope part 420 are fixed on the central part 110 of the grip rod 100, the weight 500 is easily arranged on the center line of the lower rope 400 due to gravity.

[0041] The lower ropes 400 form an inverted triangular shape between the weight 500 and the grip rod 100. Therefore, when the handle 120 is held and the grip rod 100 is rotated in one direction, the first lower rope portion 410 and the second lower rope portion 420 are spirally wound around the central portion 110 toward the center and lift the weight 500. When the handle 120 is rotated in the reverse direction to rotate the grip rod 100 in the other direction, the weight 500 descends. By repeatedly performing such actions, the forearm muscles are exercised.

[0042] The height adjustment plate 200 is located above the grip rod 100. The upper ropes 300 are connected to the grip rod 100 through the height adjustment plate 200. The first upper rope portion 310 and the second upper rope portion 320 pass through the height adjustment plate 200 and extend downward, turn around the pulley 150 to form a loop portion 350, and then are fixed to the height adjustment plate 200.

[0043] Both end portions of the upper ropes 300, namely the end portions of the first upper rope portion 310 and the second upper rope portion 320, are fixed to the height adjustment plate 200. Therefore, when the position of the height adjustment plate 200 is adjusted up and down, the size of the loop portion 350 is adjusted. The loop portion 350 is the portion where the upper ropes 300 extend and overlap. Therefore, for example, when the size of the loop portion 350 becomes larger, the height direction length of the upper ropes 300 becomes shorter. The loop portions 350 on both sides of the upper ropes 300 go around the pulley 150 of the grip rod 100. Therefore, the height of the grip rod 100 is adjusted by adjusting the height of the height adjustment plate 200. Therefore, the height of the grip rod 100 can be adjusted to a height suitable for the hanging wrist rotation exercise by moving the height adjustment plate 200 upward or downward.

[0044] Rope connection portions 250 are formed on both sides of the height adjustment plate 200 for passing through and fixing the end portions of the first upper rope portion 310 and the second upper rope portion 320.

[0045] The rope connection portions 250 include at least two through holes 252, 254 through which the first upper rope portion 310 and the second upper rope portion 320 pass and extend downward; and fixing holes 256 for fixing the first upper rope portion 310 and the second upper rope portion 320. The through holes 252, 254 and the fixing holes 256 are holes differentiated by function and may have the same shape.

[0046] According to an embodiment of the present invention, the distance between the rope connection portions 250 formed on both sides of the height adjustment plate 200 corresponds to the distance between the pulleys 150 on both sides of the grip rod 100.

[0047] The height adjustment plate 200 spaces apart the formation positions of the left and right ring portions 350 by an amount corresponding to the distance between the pulley 150. The first upper rope portion 310 and the second upper rope portion 320 passing through the height adjustment plate 200 extend almost vertically downward, bypass the pulley 150, and then extend almost vertically upward to form the ring portions 350. The left and right ring portions 350 extend almost parallel to the pulley groove 152. Therefore, when the user rotates the grip 100 by wrist rotation, even if the grip 100 swings, the ring portions 350 will not fall off from the pulley groove 152 and are stably supported.

[0048] The rope connection portion 250 includes at least two through holes 252, 254. The two through holes 252, 254 are arranged vertically. The fixing hole 256 is arranged adjacent to the through holes 252, 254.

[0049] The first upper rope portion 310 and the second upper rope portion 320 pass through the two vertically arranged through holes 252, 254 in a zigzag shape and extend downward, bypass the groove 152 of the pulley 150, and then extend upward through the fixing hole 256.

[0050] The first upper rope portion 310 and the second upper rope portion 320 passing through the fixing hole 256 are fixed by tying knots or the like. A fixing tool can be used instead of tying knots.

[0051] Figure 4 It is a partial exploded perspective view of the grip of the hanging wrist rotator according to the present invention. Figure 5 is Figure 4 The combined sectional view of the grip shown.

[0052] According to an embodiment of the present invention, the grip 100 is formed by assembling the grip body 140 and the pulley 150. The grip body 140 includes a central portion 110 and two side handles 120.

[0053] The grip body 140 includes a central portion 110 and two side handles 120. The central portion 110 is integrally formed with the two side handles 120 so as to rotate together.

[0054] The central portion 110 includes a rod-shaped central main body 114 and first engaging portions 115 formed on both sides of the central main body 114.

[0055] The central body 114 is the portion of the grip rod 100 that is wound by the lower rope 400. Lower rope fixing portions 112 in the shape of holes are formed on both sides of the central body 114 in a direction crossing the central axis in the longitudinal direction. The lower rope fixing portions 112 are symmetrically arranged at the central portion 110. The holes forming the lower rope fixing portions 112 penetrate the central body 114 in the diameter direction and have stepped surfaces inside. Therefore, after the end of the lower rope 400 is inserted through one opening of the lower rope fixing portion 112 and a knot is formed, when pulled, the end of the lower rope 400 is fixed to the lower rope engaging portion 112.

[0056] The first engaging portion 115 can be formed as a protrusion extending in the longitudinal direction. A first engaging hole 116 for the fastening member 130 is formed on the first engaging portion 115. The first engaging portion 115 is engaged with the handle 120.

[0057] The handle 120 is formed in a rod shape, and a grip groove that is easy to hold by hand can be formed on the outer peripheral surface. The handle 120 can be formed hollow. Covers 129 for blocking the hollow of the handle 120 can be engaged at both ends in the longitudinal direction.

[0058] A second engaging portion 125 that engages with the first engaging portion 115 is formed at the end facing the central portion 110 of the handle 120. The second engaging portion 125 is formed in the form of an insertion hole for inserting the first engaging portion 115. The first engaging portion 115 and the second engaging portion 125 have complementary shapes to each other.

[0059] A second engaging hole 126 that aligns with the first engaging hole 116 of the first engaging portion 115 is formed in the second engaging portion 125.

[0060] By inserting and assembling the first engaging portion 115 and the second engaging portion 125, the fastening member 130 is engaged with the aligned first engaging hole 116 and second engaging hole 126 to fix the central portion 110 and the handle 120. The fastening member can be a pin, a bolt, etc.

[0061] According to an embodiment of the present invention, the fastening member 130 is formed as a bolt having a thread formed on its outer circumferential surface and can be formed to be threadedly engaged only with the first coupling hole 116. That is, the second coupling hole 126 of the second coupling portion 125 located on the outer side of the first coupling portion 115 and the second coupling portion 125 is formed as a non-threaded insertion hole, and the first coupling hole 116 of the first coupling portion 115 located on the inner side is formed as a nut hole having a thread formed on its inner circumferential surface. When the fastening member 130 formed as a bolt is inserted through the second coupling hole 126 and threadedly fastened to the first coupling hole 116, the first coupling portion 115 is pulled toward the inner circumferential surface of the second coupling portion 125 and the bolt is tightened. As a result, while a slight compressive deformation is formed on the second coupling portion 125, the first coupling portion 115 and the second coupling portion 125 are fixed. The central portion 110 and the handle 120 are firmly fixed, so that no play occurs, and the loosening of the bolt is suppressed by the slight compressive deformation of the second coupling portion 125. This principle is similar to the fixing principle that occurs when a washer is sandwiched and a screw is assembled.

[0062] Pulleys 150 are coupled to both sides of the central portion 110 of the grip body 140. According to an embodiment of the present invention, the pulley 150 is formed as a bearing-type pulley, that is, a bearing pulley. The bearing pulley 150 is inserted into the first coupling portion 115 through the mounting hole 151, and a groove 152 is formed along the circumferential direction on the outer circumferential surface of the bearing pulley 150.

[0063] The bearing pulley 150 can be in various forms. For example, it can be a separated form in which the outer wheel and the inner wheel rotate independently, and the groove 152 is formed on the outer wheel side. Or it can be a form in which a bearing is installed on the inner surface of the bearing pulley mounted on the first coupling portion 115, or a bearing surface is formed. A bearing is a component that enables relative rotation between the shaft to be installed and the portion supported by the bearing. In the present specification, the bearing pulley 150 rotates relative to the grip body 140.

[0064] Due to the bearing pulley 150, the rotation of the grip body 140 is not transmitted to the loop portion 350 of the upper rope 300, so that the exerciser can more stably perform the action of rotating the grip 100 while holding the handle 120.

[0065] Figure 6 It is a cross-sectional view showing another embodiment of the grip of the suspension type wrist rotator of the present invention. Refer to Figure 6 , the central portion 110, the both side handles 120, and the pulleys 150 of the grip 100 can be integrally formed.

[0066] The grip body 140 is formed in a rod shape, and the handle 120 extends on both sides of the central portion 110 located in the middle. The grip body 140 can be formed to be hollow, and caps 129 for blocking the hollow of the handle 120 can be coupled to the openings at both ends in the length direction.

[0067] A pulley 150 is formed between the central part 110 and the two side handles 120. The pulley 150 is integrally formed with the grip rod body 140.

[0068] The pulley 150 protrudes radially along the grip rod body 140, and the central part is recessed circumferentially to form a groove 152.

[0069] Since the pulley 150 is integrally formed with the grip rod body 140, it rotates together with the grip rod body 140, and the pulley 150 rotates with the loop part 350 of the upper rope 300 wound around it.

[0070] On both sides of the central part 110, there are formed lower rope fixing parts 112 in the form of through holes for fixing the two side ends 415 of the lower rope 400. In an embodiment where the grip rod body 140 is formed to be hollow, the lower rope fixing parts 112 penetrate from the outer peripheral surface of the central part 110 toward the hollow interior.

[0071] The first lower rope part 410 and the second lower rope part 420 are introduced into the hollow interior of the grip 100 through the lower rope fixing parts 112 in the form of through holes and then pulled outward through the two side end openings. After that, the ends of the first lower rope part 410 and the second lower rope part 420 are knotted or fastened with fixing tools and then pulled, thereby completing the connection of the lower rope 400.

[0072] The protection scope of the present invention is not limited to the descriptions and expressions of the embodiments clearly shown and described above. Additionally, it is again pointed out that the protection scope of the present invention cannot be limited by obvious changes or substitutions in the technical field to which the present invention pertains.
