Description

Technical Field

[0001] The present invention relates to a suspended wrist roller device in which a user can rotate a grip bar to perform a wrist roller exercise while being suspended in the air.

Background Art

[0002] Among the exercises for exercising the forearm muscles, a suspended wrist roller device is known. FIG. 1 shows a suspended wrist roller device of Korean Patent Publication No. 10-2018-0010415 invented and published by the present inventor.

[0003] Referring to FIG. 1, a known suspended wrist roller device includes a grip bar 1 suspended by a string with a weight 3, and a hanger piece 5 that suspends the grip bar 1 to an upper support base (not shown) using a band-type strap 8a or a rope 8b. The hanger piece 5 is made of metal and includes an upper part 5a to which the band-type strap 8a or the rope 8b is fixed, and lower parts 5b on both sides having a loop 6 to which the grip bar 1 is hooked. The loop 6 of the lower part 5b is hooked to the loop groove 2 of the grip bar 1. The band-type strap 8a can be directly fixed to the hanger piece 5, and the rope 8b can be coupled to the hanger piece 5 via a hook 9. The suspended wrist roller device is a device that performs a wrist roller exercise by holding the grip bar with both hands in a posture with both arms extended forward while the grip bar is suspended in the air, and rotating the grip bar alternately with one hand at a time. The suspended wrist roller device is advantageous for evenly exercising the forearm muscles of both arms.

[0004] By the way, known hanging list roller devices have the following problems. First, there is a disadvantage that it is difficult to adjust the height of the grip bar. Generally, it is known that a hanging list roller device is effective in performing movements with both arms extended parallel. By the way, since a known hanging list roller device is fixed at the height at which it is installed for the first time, there is a disadvantage that it is difficult for the exerciser to adjust the height of the grip bar according to his or her body. Second, since the ring of the hanger piece is in a form where a part is opened for inserting the grip bar, care is required so that the grip bar does not come off during exercise. Third, friction occurs between the ring of the hanger piece made of metal and the grip bar according to the rotation of the grip bar, which hinders the balance of the movement and causes noise and wear.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, specific contents for carrying out the present invention will be described with reference to the accompanying drawings. And when explaining the present invention, for known functions, if it is determined that it is obvious to those skilled in the art and can unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

[0016] FIG. 2 is a front view of a suspension list roller device according to an embodiment of the present invention, and FIG. 3 is a partially enlarged perspective view of the suspension list roller device according to the present invention, where FIGS. 3(a) and 3(b) show opposite directions.

[0017] Referring to FIGS. 2 and 3, the suspension list roller device according to an embodiment of the present invention includes a grip bar 100 and a height adjustment plate 200, and includes an upper rope 300 for hanging the grip bar 100 on a support base 10 disposed on the upper side, and a lower rope 400 for hanging a weight 500 on the grip bar 100.

[0018] The grip bar 100 includes a center portion 110, left and right handles 120 respectively provided on both sides of the center portion 110, and a sheave 150 located between the center portion 110 and the left and right handles 120.

[0019] The center portion 110 is located in the middle of the grip bar 100 and is a portion around which the lower rope 400 is wound, and may be formed in a cylindrical shape.

[0020] On both sides of the center part 110, lower rope fixing parts 112 to which both end parts of the lower rope 400 are respectively fixed are formed.

[0021] The handle 120 is a part where a user holds the grip bar 100 by hand and is arranged on both sides of the center part 110. The handle 120 is formed to rotate together with the center part 110. The left and right handles 120 may be integrally formed with the center part 110 or integrally coupled.

[0022] On both sides of the center part 110, sheaves 150 are provided between the left and right handles 120. The sheave 150 includes a groove 152 formed in the circumferential direction of the grip bar 100. The sheave 150 is a part where a loop part 350 formed at the lower part of the upper rope 300 is supported, and the loop part 350 is hung on the groove 152 of the sheave 150.

[0023] The upper rope 300 connects the support base 10 located on the upper side and the grip bar 100 and functions to suspend the grip bar 100 in the air. The support base 10 is presented in a rod form in FIG. 2, but is not limited thereto and may have various forms. For example, it may be a ring suspended from a structure to which a string can be fixed. When the support base 10 is in a rod shape, it may be connected by forming a knot.

[0024] The upper rope 300 includes first and second upper rope parts 310 and 320 that branch off from the support base 10 and extend downward. The upper rope 300 may be formed of a single rope. The central part of the upper rope 300 is connected to the support base 10 while forming a knot 302, and both side parts extend downward while forming the first and second upper rope parts 310 and 320.

[0025] The loop part 350 is formed at the lower parts on both sides of the upper rope 300. Both side parts of the upper rope 300, that is, the first and second upper rope parts 310, 320 are extended downward via the height adjustment plate 200, the direction is changed through the groove 152 of the sheave 150, and after being extended upward, the loop part 350 is formed in a manner of being fixed to the height adjustment plate 200.

[0026] The lower rope 400 has a function of hanging the weight 500 on the grip bar 100. It includes the first and second lower rope parts 410, 420 which are connected to the weight 500 at the lower end of the lower rope 400 and branched and extended upward.

[0027] The lower rope 400 may be formed of a single rope. The lower rope 400 is extended upward while passing through the loop formed at the upper end of the weight 500, and one side and the other side parts which are branched and extended become the first and second lower rope parts 410, 420.

[0028] Both upper ends of the lower rope 400 are fixed to the lower rope fixing parts 112 formed on both sides at the center part 110 of the grip bar 100. The lower rope fixing parts 112 may be formed of holes located on both sides of the center part 110. The rope fixing parts will be described later.

[0029] If the upper ends of the first and second lower rope parts 410, 420 are fixed to the center part 110 of the grip bar 100, the weight 500 is easily arranged on the center line of the lower rope 400 by the weight.

[0030] The lower rope 400 forms an inverted triangle shape between the weight 500 and the grip bar 100. Therefore, while holding the handle 120 and rotating the grip bar 100 in one side direction, the first and second lower rope parts 410, 420 are spirally wound toward the center on the center part 110, and the weight 500 is lifted. When the handle 120 is rotated in the opposite direction and the grip bar 100 is rotated in the other side direction, the weight 500 is lowered. The forearm muscles are exercised while repeating such an operation.

[0031] The height adjustment plate 200 is positioned above the grip bar 100. The upper rope 300 passes through the height adjustment plate 200 and is connected to the grip bar 100. The first and second upper rope portions 310, 320 pass through the height adjustment plate 200 and extend downward. After being hung on the sheave 150, the direction is changed to form the loop portion 350, and then it is fixed to the height adjustment plate 200.

[0032] Since both side ends of the upper rope 300, that is, the ends of the first and second upper rope portions 310, 320, are fixed to the height adjustment plate 200, when adjusting the position of the height adjustment plate 200 up and down, the size of the loop portion 350 is adjusted. Since the loop portion 350 is a portion where the upper rope 300 extends so as to overlap, for example, if the size of the loop portion 350 increases, the length of the upper rope 300 in the height direction becomes shorter. Since the sheaves 150 of the grip bar 100 are hung on the loop portions 350 on both sides of the upper rope 300, the height adjustment of the height adjustment plate 200 leads to the height adjustment of the grip bar 100. Therefore, the height of the grip bar 100 can be adjusted to a suitable height for the hanging list roller movement by moving the height adjustment plate 200 upward or downward.

[0033] On both sides of the height adjustment plate 200, rope connection portions 250 are formed through which the first and second upper rope portions 310, 320 pass and whose ends are fixed.

[0034] The rope connection portion 250 includes at least two through holes 252, 254 that extend downward through the first and second upper rope portions 310, 320, and fixing holes 256 for fixing the first and second upper rope portions. The through holes 252, 254 and the fixing holes 256 are functionally divided and may have the same form.

[0035] 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 sheaves 150 on both sides of the grip bar 100.

[0036] The formation positions of the loop portions 350 on both sides can be separated by the height adjustment plate 200 only corresponding to the distance from the sheave 150. The first and second upper rope portions 310 and 320 passing through the height adjustment plate 200 are extended downward substantially vertically and hung on the sheave 150, and extended upward substantially vertically to form the loop portions 350. Since the left and right loop portions 350 are extended substantially parallel to the sheave groove 152, even if a swing occurs in the grip bar 100 while the user turns the grip bar 100 for the wrist roller, the grip bar 100 loop portion 350 is stably supported without being detached from the sheave groove 152.

[0037] The rope connection portion 250 includes at least two through holes 252 and 254. The two through holes 252 and 254 are arranged vertically. The fixing hole 256 is arranged adjacent to the through holes 252 and 254.

[0038] The first and second upper rope portions 310 and 320 pass through the two vertically arranged through holes 252 and 254 in a zigzag manner and extend downward, are hung on the groove 152 of the sheave 150 and then extended upward, and then pass through the fixing hole 256.

[0039] The first and second upper rope portions 310 and 320 passing through the fixing hole 256 are fixed by means such as knots. A fixture may be used instead of the knot.

[0040] FIG. 4 is a partially exploded perspective view of the grip bar of the suspension wrist roller device according to the present invention, and FIG. 5 is a combined cross-sectional view of the grip bar shown in FIG. 4.

[0041] According to an embodiment of the present invention, the grip bar 100 includes a grip bar body 140 including a center portion 110 and both side handles 120 and a sheave 150, and is assembled with each other.

[0042] The grip bar body 140 includes a center portion 110 and both side handles 120. The center portion 110 and both side handles 120 are coupled and integrated to rotate together.

[0043] The center portion 110 includes a rod-shaped center body 114 and first coupling portions 115 formed on both sides of the center body 114.

[0044] The center body 114 is a portion where the lower rope 400 is wound around the grip rod 100. On both sides of the center body 114, lower rope fixing portions 112 in the form of holes are formed in a direction intersecting the central axis in the longitudinal direction. The lower rope fixing portions 112 are symmetrically arranged with respect to the center portion 110. The holes forming the lower rope fixing portions 112 are formed to penetrate the center body 114 in the diameter direction and have a stepped surface inside. Therefore, when the end of the lower rope 400 is inserted through one side opening of the lower rope fixing portion 112, a knot is formed at the end and then pulled, the end of the lower rope 400 is fixed to the lower rope fixing portion 112.

[0045] The first coupling portion 115 may be formed of a protruding portion extending in the longitudinal direction. A first coupling hole 116 for the fastening member 130 is formed in the first coupling portion 115. A handle 120 is coupled to the first coupling portion 115.

[0046] The handle 120 is formed in a rod shape, and grip grooves may be formed on the outer peripheral surface so that it is easy to hold by hand. The handle 120 may be formed hollow. Caps 129 for preventing the hollow of the handle 120 may be coupled to both ends of the handle 120 that are open in the longitudinal direction.

[0047] A second coupling portion 125 for coupling to the first coupling portion 115 is formed at the end of the handle 120 facing the center portion 110. The second coupling portion 125 is formed in the form of an insertion hole into which the first coupling portion 115 is inserted. The first coupling portion 115 and the second coupling portion 125 have complementary shapes to each other.

[0048] A second coupling hole 126 that is aligned with the first coupling hole 116 of the first coupling portion 115 is formed in the second coupling portion 125.

[0049] The center part 110 and the handle 120 are fixed by inserting and assembling a first coupling part 115 and a second coupling part 125 and coupling a fastening member 130 through the first coupling holes 116 that match via the second coupling holes 126. As the fastening member, a pin, a bolt, or the like may be used. When a bolt is used as the fastening member, the second coupling hole 126 can be formed in a form that does not completely penetrate the second coupling part 125. Therefore, the lower part 126a of the second coupling hole 126 can be formed inside the second coupling part 125.

[0050] According to an embodiment of the present invention, the fastening member 130 may be formed of a bolt having a thread formed on its outer peripheral surface and may be formed to be threadedly coupled only to the first coupling hole 116. That is, the second coupling hole 126 of the second coupling part 125 located outside of the first coupling part 115 and the second coupling part 125 is formed as an insertion hole without a thread, and the first coupling hole 116 of the first coupling part 115 located inside is formed as a nut hole having a thread formed on its inner peripheral surface. When the fastening member 130 formed of a bolt is inserted through the second coupling hole 126 and threadedly fastened to the first coupling hole 116, the first coupling part 115 is pulled by the inner peripheral surface of the second coupling part 125 and the bolt is tightened. As a result, while the second coupling part 125 is slightly compressed and deformed, the first coupling part 115 and the second coupling part 125 are fixed. Since the center part 110 and the handle 120 are firmly fixed, play does not occur, and loosening of the bolt is suppressed by the slight compression deformation of the second coupling part 125. Such a principle is similar to the fixing principle that occurs when assembling a screw via a washer.

[0051] Sheaves 150 are coupled to both sides of the center part 110 to the grip bar body 140. According to an embodiment of the present invention, the sheaves 150 are formed of a bearing type sheave, that is, a bearing sheave. The bearing sheave 150 is inserted into the first coupling part 115 through the mounting hole 151, and a groove 152 is formed in the circumferential direction on the outer peripheral surface of the bearing sheave 150.

[0052] The bearing sheave 150 may be in various forms. For example, it may be in a form where the outer ring and the inner ring are separated so as to rotate individually and a groove 152 is formed on the outer ring side. Or, a bearing may be mounted on the inner surface of the bearing sheave mounted on the first coupling portion 115, or a bearing surface may be formed. A bearing is a component that allows relative rotation between the shaft on which it is mounted and the portion supported by the bearing. In this specification, the bearing sheave 150 rotates relative to the grip bar body 140.

[0053] Since the rotation of the grip bar body 140 is not transmitted to the loop portion 350 of the upper rope 300 by the bearing sheave 150, the operation of the athlete turning the grip bar body 140 while holding the handle 120 may be performed more stably.

[0054] FIG. 6 is a cross-sectional view showing another embodiment of the grip bar of the suspension roller device according to the present invention. Referring to FIG. 6, the grip bar 100, the center portion 110, the handles 120 on both sides, and the sheave 150 may be integrally formed.

[0055] The grip bar body 140 is formed in a bar shape, and the handles 120 extend on both sides of the center portion 110 located in the middle. The grip bar body 140 may be formed hollow, and caps 129 for preventing the hollow of the handle 120 may be coupled to the openings at both longitudinal ends.

[0056] A sheave 150 is formed between the center portion 110 and the handles 120 on both sides. The sheave 150 is integrally formed with the grip bar body 140.

[0057] The sheave 150 protrudes in the radial direction of the grip bar body 140, and the center portion is recessed in the circumferential direction to form a groove 152.

[0058] Since the sheave 150 is integrally formed with the grip bar body 140, it rotates together with the grip bar body 140, and the sheave 150 rotates in a state of being hung on the loop portion 350 of the upper rope 300.

[0059] On both sides of the center portion 110, lower rope fixing portions 112 in the form of through holes are formed to which both end portions 415 of the lower rope 400 are fixed. In an embodiment in which the grip bar body 140 is formed hollow, the lower rope fixing portions 112 penetrate from the outer peripheral surface of the center portion 110 toward the hollow interior.

[0060] After the first and second lower rope portions 410, 420 are introduced into the hollow interior of the grip bar 100 through the lower rope fixing portions 112 in the form of through holes, they are pulled outward through the openings at both ends. Then, after the ends of the first and second lower rope portions 410, 420 are tied together or pulled after being bound with a fixture, the connection of the lower rope 400 is completed.

[0061] The protection scope of the present invention is not limited by the description and expression of the embodiments explicitly described above. Additionally, it is reiterated that the protection scope of the present invention is not limited by obvious changes and substitutions in the technical field to which the present invention pertains.
