[0004] Such fitness equipment can be classified according to the purpose of exercise, such as upper body muscle training, lower body muscle training, and abdominal muscle training. Representative fitness equipment for upper body muscle training includes T-bar row machines, shoulder press machines, and long pull machines.

[0005] Korean Patent No. 10-2154302 (granted on Sep. 3, 2020) discloses a back muscle strengthening exercise apparatus. According to the disclosed technology, the back muscle strengthening exercise apparatus includes: a base frame including a horizontal frame that supports a floor surface and a vertical frame vertically provided at the front of the horizontal frame; a seat portion vertically provided at the rear of the horizontal frame; and a movable member rotatably provided at an upper end of the vertical frame. The movable member is integrally formed such that a support member and a load member intersect in an L-shape, and a hinge coupling means is provided at the intersection of the support member and the load member to be hinge-coupled to the upper end of the vertical frame. An external force applying means is coupled to an end of the support member, and a load adjusting means is provided at an end of the load member. The external force applying means includes: a hollow rod orthogonally provided to the end of the support member; a solid rod inserted into the hollow rod and protruding from both ends thereof; and an intermediate shaft member, one end of which is rotatably coupled to the solid rod about the solid rod. A bushing and a hollow member are sequentially provided along a longitudinal direction at the other end of the intermediate shaft member, and an extension shaft member penetrates through the centers of the bushing and the hollow member and is coupled to the other end of the intermediate shaft member, so that the bushing and the hollow member are rotatably coupled to the extension shaft member. A U-shaped handle is integrally coupled to the outer circumferential surface of the hollow member, and the hollow member rotates on a two-dimensional plane about the extension shaft member depending on the direction of the force applied to the handle.

[0006] Korean Patent Publication No. 10-2024-0108976 (published on Jul. 10, 2024) discloses a multifunctional exercise handle. According to the disclosed technology, the multifunctional exercise handle includes: a grip body made of medical silicone material and grasped by a user's hand; a hand cover provided at a lower portion of the grip body to be attachable / detachable from the grip body, made of medical silicone material, and either grasped together with the grip body by the user or spaced apart from the grip body when the grip body is grasped by the user's hand; a nylon strap formed in a closed loop shape that vertically passes through one end of the grip body, extends horizontally through the interior of the hand cover, and vertically passes through the other end of the grip body; and a coupling member fixed to an upper portion of the strap and coupled to the exercise equipment.

[0056] The fixing part 300 fixes the rotatable handle part 200 after rotation to prevent further rotation.

[0057] In one embodiment, the fixing part 300 may include a fixing frame 310, a rotating frame 320, and a fixing pin 330.

[0058] The fixing frame 310 includes a plurality of angle adjustment holes 311 radially arranged around the circumference thereof, and the coupling part 100 is inserted and fixed at the center thereof.

[0059] In one embodiment, the fixing frame 310 may include an insertion hole formed at the center for inserting the coupling part 100, and the coupling part 100 may be inserted and fixed into the insertion hole.

[0060] The rotating frame 320 has one side coupled to the other side of the outer ring of the bearing 220 to rotate together with the outer ring of the bearing 220, and includes a through-hole 321 formed on the other side thereof.

[0061] In one embodiment, the left side of the rotating frame 320 may be coupled to the lower side of the outer ring of the bearing 220, and the through-hole 321 is formed on the right side thereof.

[0062] In one embodiment, the rotating frame 320 may include an insertion hole formed on one side thereof, so the other side of the outer ring of the bearing 220 may be inserted and coupled into the insertion hole and may be integrally coupled by welding.

[0063] The fixing pin 330 is inserted into the through-hole 321 of the rotating frame 320 and the angle adjustment hole 311 of the fixing frame 310 to prevent the outer ring of the bearing 220 from rotating.

[0064] Accordingly, when adjusting the rotation angle of the rotatable handle part 200, the user may grip the handle 240 and rotate it to a desired angle, and then insert the fixing pin 330 into the through-hole 321 and the angle adjustment hole 311 to fix the handle 240 at the adjusted angle.

[0065] In one embodiment, the fixing pin 330 may include a plunger body 331, body grooves 332, a plunger pin 333, a spring 334, a plunger cap 335, and locking protrusions 336.

[0066] The plunger body 331 includes a central hole 331a formed vertically at the center, and the outer surface of the plunger body is coupled to the through-hole 321 of the rotating frame 320.

[0067] In one embodiment, a lower portion of the plunger body 331 is inserted into the through-hole 321 and an upper portion thereof is seated on an upper portion of the through-hole 321.

[0068] In one embodiment, a lower outer surface of the plunger body 331 may be threaded to be screw-coupled to the through-hole 321.

[0069] Two body grooves 332 are formed respectively on both sides of the upper portion of the plunger body 331 to receive the locking protrusions 336.

[0070] In one embodiment, the body grooves 332 may be formed in a rectangular shape and may be respectively formed on both sides of the upper portion of the plunger body 331.

[0071] The plunger pin 333 is slidably installed in the central hole 331a of the plunger body 331 in a vertical direction, and a lower end thereof is selectively inserted into the angle adjustment hole 311 of the fixing frame 310.

[0072] The spring 334 is installed between the plunger body 331 and the plunger pin 333 to provide an elastic force to the plunger pin 333.

[0073] In one embodiment, one end of the spring 334 is coupled to an upper portion of the central hole 331a of the plunger body 331, and the other end thereof is coupled to the central portion of the plunger pin 333.

[0074] The plunger cap 335 is coupled to an upper portion of the plunger pin 333 and allows the user to grip and pull the plunger cap to adjust the position of the plunger pin 333.

[0075] In one embodiment, the plunger cap 335 may include a fixing groove at a lower central portion to insert and fix the upper portion of the plunger pin 333.

[0076] Two locking protrusions 336 are formed to protrude respectively from the both lower sides of the plunger cap 335, and are inserted into the body grooves 332 or caught on the upper portion of the plunger body 331.

[0077] In one embodiment, the locking protrusions 336 may be formed as rectangular protrusions on the left and right lower sides of the plunger cap 335.

[0078] As described above, the handle for fitness equipment allows the rotatable handle part 200 to be rotated according to user's needs and fixes the rotatable handle part 200 using the fixing part 300 after rotation to ensure safety, thereby ensuring safety and facilitate exercise, reducing the risk of injury, and enabling safe use even for patients requiring rehabilitation.

[0079] Furthermore, the handle for fitness equipment having the above configuration can be used in various ways depending on the purpose of exercise. For example, one handle may be installed on one side of fitness equipment so that the user can grip it with one hand, two handles are installed on both sides of the fitness equipment for two-handed use. Accordingly, the handle for fitness equipment having the above configuration according to the present invention is applicable to various types of fitness equipment.

[0080] FIG. 4 is a diagram illustrating the operation of the fixing pin in FIG. 1.

[0081] Referring to FIG. 4, when the user pulls the plunger cap 335 upward, the spring 334 is compressed, and the lower end of the plunger pin 333 is released from the angle adjustment hole 311. When the user releases the pulling force on the plunger cap 335, the lower end of the plunger pin 333 is reinserted into the angle adjustment hole 311 by the restoring force of the compressed spring 334.

[0082] That is, as illustrated in FIG. 4(b), when the user rotates the plunger cap 335 at a predetermined angle in the upwardly pulling state, the locking protrusions 336 are caught on the upper portion of the plunger body 331 to maintain the upward-pulled state of the plunger cap 335. At this time, the plunger pin 333 slides upward together with the plunger cap 335, so that the lower end of the plunger pin 333 is separated from the angle adjustment hole 311, thereby allowing rotation of the rotatable handle part 200.

[0083] As illustrated in FIG. 4(a), when the user releases the pulling force while rotating the plunger cap at the predetermined angle after pulling the plunger cap 335 upward, the plunger pin 333 returns to its original position by the restoring force of the spring 334, and the locking protrusions 336 are inserted into the body grooves 332. At this time, the plunger pin 333 slides downward together with the plunger cap 335, and the lower end of the plunger pin 333 is inserted into the angle adjustment hole 311, thereby fixing the rotatable handle part 200 from further rotation.

[0084] FIG. 5 is a perspective view illustrating a handle for fitness equipment according to a second embodiment of the present invention.

[0085] Referring to FIG. 5, the handle for fitness equipment includes a coupling part 100, a rotatable handle part 200, a fixing part 300, and a connection part 400. Since the coupling part 100, the rotatable handle part 200, and the fixing part 300 are similar to the components in FIG. 1, their description is omitted, and only the different parts will be described below.

[0086] The connection part 400 protrudes from the coupling part 100 and is connected to a cable C of the fitness equipment.

[0087] In one embodiment, the connection part 400 may protrude from a central portion on the other side of the coupling part 100 and may include a through-hole. That is, a hook installed at the end of the cable C, which transfers the load of a weight of the fitness equipment, can be hooked and connected to the through-hole.

[0088] In one embodiment, the connection part 400 may protrude from a lower portion of the coupling part 100.

[0089] In the case of a single-function machine such as a chest press machine, in which a user grips the handle and pushes forward, or a shoulder press machine, in which a user grips the handle with both hands and lifts upward while seated, the handle for fitness equipment may be formed as an integrated type in which the coupling part 100 is integrally welded to the fitness equipment. Alternatively, in the case of a cable machine which adjusts the height and direction of pulleys that guide the cable according to the desired muscle group to perform exercises for various muscles in the body, the handle may be formed as a detachable type in which the cable is connected to the connection part 400.

[0090] FIG. 6 is a block diagram illustrating a handle for fitness equipment according to a third embodiment of the present invention, and FIG. 7 is a cross-sectional view illustrating the handle for fitness equipment according to the third embodiment of the present invention.

[0091] Referring to FIGS. 6 and 7, the handle for fitness equipment further includes a plurality of button switch units 500, a memory unit 600, a control unit 700, a notification unit 800, and a display unit 900.

[0092] The plurality of button switch units 500 are respectively installed on a plurality of angle adjustment holes 311 provided in the fixing frame 310. When button switch unit 500 is pressed by the fixing pin 330 inserted into the angle adjustment hole 311, the button switch unit 500 is turned on, and when the fixing pin 330 is separated from the angle adjustment hole 311 and the pressing is released, the button switch unit 500 is turned off.

[0093] In one embodiment, each button switch unit 500 may include a button formed to be slanted downward so that the fixing pin 330 can easily press the button and be inserted into the angle adjustment hole 311.

[0094] The memory unit 600 sets and stores in advance the rotation angles of the handle 240 corresponding to the respective positions of the plurality of button switch units 500.

[0095] The control unit 700 generates a notification signal when all of the plurality of button switch units 500 are turned off, or, when any one of the button switch units 500 is turned on, reads the rotation angle of the handle 240 corresponding to the position of the button switch unit 500 that is turned on from the memory unit 600.

[0096] The notification unit 800 receives the notification signal from the control unit 700 and informs the user.

[0097] In one embodiment, the notification unit 800 may be installed on the rotatable handle part 200 or the fixing part 300, and may be installed at various positions as needed.

[0098] In one embodiment, the notification unit 800 may include a speaker for outputting a warning sound in response to the notification signal generated by the control unit 700.

[0099] In one embodiment, the notification unit 800 may include a light-emitting lamp that emits light to visually notify the user in response to the notification signal generated by the control unit 700.

[0100] In one embodiment, the notification unit 800 may include a vibrator for generating vibration in response to the notification signal generated by the control unit 700.

[0101] The display unit 900 displays the rotation angle of the handle 240 read by the control unit 700 on a screen.

[0102] In one embodiment, the display unit 900 may be installed on the rotatable handle part 200 or the fixing part 300, and may be installed together with the notification unit 800.

[0103] In one embodiment, the display unit 900 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED).

[0104] The handle for fitness equipment having the above configuration can notify the user via the notification unit 800 when all the button switch units 500 are turned off, thereby preventing the user from exercising while the fixing pin 330 is not inserted into the angle adjustment hole 311. The handle for fitness equipment also encourages the user to always insert the fixing pin 330 into the angle adjustment hole 311 to firmly fix the outer ring of the bearing 220 from rotation, thereby significantly improving safety.

[0105] In addition, since the display unit 900 displays the rotation angle of the handle 240 corresponding to the position of the button switch unit 500 that is turned on, the user can easily and accurately check the rotation angle of the handle 240.

[0106] For example, the rotation angle of the handle 240 corresponding to the button switch unit 500 at position 1 may be preset and stored as 0°, that of position 2 as 30°, that of position 3 as 60°, and that of position 4 as 90°. When the button switch unit 500 at position 4 is turned on, the display unit 900 displays the preset rotation angle of the handle 240, which is 90°.

[0107] FIG. 8 is a block diagram illustrating a handle for fitness equipment according to a fourth embodiment of the present invention.

[0108] Referring to FIG. 8, the handle for fitness equipment further includes a pressure sensing unit 1000, a pressure memory unit 1100, a pressure control unit 1200, and a pressure notification unit 1300.

[0109] The pressure sensing unit 1000 is formed on the inner side of the coupling part 100 to sense pressure applied by the shaft 210.

[0110] In one embodiment, the pressure sensing unit 1000 may be composed of a piezoelectric sensor or the like, and may be installed in a circular hole formed at the center of the coupling part 100 to sense the pressure applied by the shaft 210 inserted into the circular hole, and transmit the sensed pressure to the pressure control unit 1200.

[0111] The pressure memory unit 1100 sets and stores a reference pressure.

[0112] The pressure control unit 1200 generates a warning signal when the pressure sensed by the pressure sensing unit 1000 is lower than the reference pressure stored in the pressure memory unit 1100 and transmits the generated warning signal to the pressure notification unit 1300.

[0113] The pressure notification unit 1300 receives the warning signal from the pressure control unit 1200 and notifies the user.

[0114] In one embodiment, the pressure notification unit 1300 may be installed on the rotatable handle part 200 or the fixing part 300 and may be installed at various locations as necessary.

[0115] In one embodiment, the pressure notification unit 1300 may include a speaker for outputting an alarm sound in response to the warning signal generated by the pressure control unit 1200.

[0116] In one embodiment, the pressure notification unit 1300 may include a light-emitting lamp that emits light to visually notify the user in response to the warning signal generated by the pressure control unit 1200.

[0117] In one embodiment, the pressure notification unit 1300 may include a vibrator for generating vibration in response to the warning signal generated by the pressure control unit 1200.

[0118] The handle for fitness equipment having the above configuration determines that the coupling between the coupling part 100 and the shaft 210 is loosened when the pressure sensed by the pressure sensing unit 1000 is lower than the reference pressure stored in the pressure memory unit 1100, and notifies the user so that the user can securely tighten the coupling between the coupling part 100 and the shaft 210. Accordingly, potential risks which may occur during exercise, for example, separation of the shaft210 from the coupling part 100, can be eliminated, ensuring safe use at all times.

[0119] The embodiments of the present invention described above are not limited to the described apparatuses and / or operation methods.
