Description

Technical Field

[0001] The present invention relates to a variable grip handle for fitness equipment, and more specifically, to a variable grip handle for fitness equipment, which not only allows a user to freely adjust the grip of a handle connected to the end of a rope for transmitting the load of a counterweight of the fitness equipment at a desired angle, but also allows the grip to freely rotate during exercise to expand the range of activity and contraction of the exercise part, thereby maximizing the exercise effect. Background Art

[0002] Weight training, commonly referred to as "fitness", is a type of exercise that promotes muscle development by repeatedly applying weight to the body's muscles. It increases the size of muscle fibers and improves muscle strength by stimulating the body's muscles to swell, and increases blood flow to ensure smooth blood supply to various parts of the body, thereby increasing vitality. It also effectively improves other body functions through the expansion of new cells and muscle tissue and improved endocrine circulation, thereby enhancing resistance to disease and delaying aging. In addition, it not only makes the appearance healthy, but also improves the efficiency of the nervous, respiratory, circulatory, reproductive, digestive and excretory functions by strengthening the body's metabolism.

[0003] In the past, weight training was mainly performed using simple weight equipment such as dumbbells and barbells (weight trainers), but weight training using these dumbbells or barbells may result in a high risk of injury due to maintaining an incorrect posture during exercise. Therefore, in recent years, various types of weight training equipment (hereinafter referred to as "fitness equipment") have become widely popular. These equipment can lift a weight connected to a rope in a specified direction while maintaining a constant and stable posture, thereby reducing the risk of injury by maintaining a correct posture while being able to more effectively exercise various muscle parts of the body.

[0004] In addition, among various fitness equipment, there are both single-type equipment for exercising specific muscles of the body and compound equipment that can exercise multiple muscles of the body.

[0005] Taking single-type equipment as an example, there are seated chest press trainers, in which the user sits on a seat, holds the handles with both hands, and pushes forward to exercise the chest and shoulders; or seated shoulder press trainers, in which the user sits on a seat, holds the handles with both hands, and pushes upward to exercise the shoulders. These single-type equipment usually have a single direction of movement to exercise specific muscles of the body, so the handles are fixed to the frame in a specified direction and angle.

[0006] A typical example of a composite machine is a cable machine, which can exercise various muscles of the body by adjusting the height and direction of the pulley for guiding the cable according to the desired exercise part, and when using these cable machines for exercise, various types of handles can be selectively attached to or detached from the ends of the cable to maintain an optimal grip according to the desired muscle part or exercise type.

[0007] That is, the rope machine can selectively use various straight handles according to the exercise part or exercise direction, for example, a straight handle in the shape of a straight rod of a predetermined length, a flexible rope handle of a predetermined length, a push-down handle formed in a V-shape separated by a predetermined angle and used for vertical movement, a chinning handle formed in a V-shape separated by a predetermined angle and with both hands gripping along the vertical direction and used for horizontal movement, etc.

[0008] In addition, there is an exercise called Cable Seated Low in the exercise that uses cable equipment, which is used to strengthen the latissimus dorsi, trapezius and rhomboid muscles located in the lower part of the back muscles of the body.

[0009] Seated cable rowing is an exercise in which you sit on a prepared seat in front of a cable machine, keep your body upright, hold the handles connected to the cable with both hands, and use your arms to pull the handles toward your body to stimulate the latissimus dorsi.

[0010] However, when using a seated cable rowing machine, a straight handle in the shape of a straight rod of a predetermined length or a pull-up handle formed in a vertical direction with a two-hand grip is mainly used. When using such a traditional handle, since the forearm and wrist below the elbow are fixed, there is a disadvantage that the muscle area stimulated during the pulling of the rope is limited.

[0011] Therefore, in order to compensate for these shortcomings, when using the handle to pull the rope, the lower part of the forearm is rotated inward to maintain the internal rotation state, or the forearm is rotated outward to maintain the external rotation state, so that the grip handle can be pulled, which can involve more muscle parts to be stimulated. However, since the traditional handle is difficult to rotate or adjust the angle, it is difficult to stably maintain the internal rotation or external rotation state.

[0062] Will refer to Figures 1 to 8 Provide explanation.

[0063] The variable grip handle of the fitness equipment of the present invention according to the preferred embodiment includes a handle frame 10 , a grip portion 20 and a plunger portion 30 .

[0064] The handle frame 10 is connected to the end of a rope for receiving the load transmitted by the weight block of the fitness equipment, and includes a main board 101 , a first combining hole 102 , a second combining hole 103 and a connecting portion 104 .

[0065] The main board 101 is made of a metal plate of a specified thickness and has no limitation on length. However, considering its use as a fitness machine, it is preferably constructed with a length of 30 to 100 cm.

[0066] The first coupling holes 102 are formed on both sides of the main board 101 and are coupled to the gripping portion 20 .

[0067] It should be noted that although the first coupling hole 102 is preferably formed by an internal thread, it is not limited thereto.

[0068] The second coupling hole 103 is formed at one side of the first coupling hole 102 and coupled with the plunger part 30 .

[0069] It should be noted that, although the second coupling hole 103 is also preferably formed by an internal thread, it is not limited thereto.

[0070] The connection part 104 is formed to protrude at the center of one side of the main board 101, and by providing a through hole 104a in the connection part 104, a hook provided at the end of a rope for receiving a load transmitted by a weight block of the fitness equipment can be hung on the through hole 104a for connection.

[0071] The gripping portion 20 is rotatably symmetrically coupled to one side of both ends of the handle frame 10 , and includes a gripping frame 201 , a bearing 202 and an angle adjustment hole 203 .

[0072] The holding frame 201 is made of a metal plate of a specified thickness and is bent so that both ends are at right angles, a setting hole 201a is formed at one end of the holding frame 201, and the holding frame 201 is rotatably connected to the handle frame 10 by a connecting unit 201b that passes through a first connecting hole 102 formed on a main board 101 of the handle frame 10 and the setting hole 201a, and a grip rod 201c is rotatably provided at the other end of the holding frame 201.

[0073] It should be noted in advance that the coupling unit 201 b is preferably composed of a bolt that passes through the coupling hole and the setting hole 201 a and a nut that is threadedly coupled to the bolt, but is not limited thereto.

[0074] The gripping rod 201c is preferably formed of a rod body of a predetermined size, and is preferably surface-processed, such as grooves or knurling, to avoid slipping when gripping.

[0075] The bearing 202 is disposed in the setting hole 201 a of the gripping frame 201 in an interference fit manner, and supports the gripping frame 201 coupled to the handle frame 10 in a rotatable manner.

[0076] The angle adjustment holes 203 are formed in a plurality of radial shapes around the setting hole 201 a of the grip frame 201 .

[0077] Therefore, when adjusting the angle of the gripping portion 20 rotatably set on the handle frame 10, the gripping frame 201 is set to a desired angle, and the gripping portion 20 whose angle adjustment has been completed is fixed by inserting the plunger pin 302 of the plunger portion 30 into the angle adjustment hole 203 radially formed around the setting hole 201a of the gripping frame 201.

[0078] The plunger portion 30 is disposed at the other side of both ends of the handle frame 10 and provides a selective fixing force to the grip portion 20 , and includes a plunger body 301 , a plunger pin 302 , an elastic member 303 and a plunger cap 304 .

[0079] The plunger body 301 is coupled to the second coupling hole 103 of the handle frame 10 .

[0080] When the first coupling hole 102 is formed by an internal thread, an external thread portion is preferably provided at one end of the plunger body 301 .

[0081] A center hole 301a is formed at the center of the plunger body 301, and the plunger pin 302 is slidably arranged in the center hole 301a. A clamping portion 301c for keeping the plunger pin 302 pushed out of the angle adjustment hole 203 of the holding frame 201 and a placing portion 301d for keeping the plunger pin 302 inserted into the angle adjustment hole 203 of the holding frame 201 are formed at the other end of the plunger body 301.

[0082] The plunger pin 302 slidably penetrates the central hole 301a of the plunger body 301, and its two end portions are formed with different diameters. A step portion 302a is formed at the midpoint so that one end of the plunger pin 302 can be selectively inserted into the angle adjustment hole 203 of the grip 20.

[0083] The elastic member 303 is disposed between a snap-fitting flange 301 b formed inside the central hole 301 a of the plunger body 301 and a step portion 302 a of the plunger pin 302 to provide elastic force to the plunger pin 302 , thereby allowing the elastic force to act on the plunger pin 302 .

[0084] The plunger cap 304 is coupled to the other end of the plunger pin 302 to adjust the position of the plunger pin 302 sliding in the plunger body 301 .

[0085] That is, if the plunger pin 302 is pulled outward by the plunger cap 304, the elastic member 303 is compressed and one end of the plunger pin 302 is pushed out from the angle adjustment hole 203 of the holding portion 20. If the force pulling the plunger cap 304 outward is released, one end of the plunger pin 302 will be reinserted into the angle adjustment hole 203 of the holding portion 20 due to the restoring force of the elastic member 303.

[0086] In addition, an insertion groove into which the engaging portion 301 c of the plunger body 301 is inserted is formed on the inner side surface of the plunger cap 304 .

[0087] Therefore, if the plunger cap 304 is pulled outward and rotated at a predetermined angle, the inner end of the plunger cap 304 is stuck in the clamping portion 301c of the plunger body 301, and the plunger cap 304 remains in the pulled state. If the plunger cap 304 stuck in the clamping portion 301c of the plunger body 301 is pulled outward and then rotated at a specified angle while the force pulling the plunger cap 304 is released, the plunger pin 302 returns to its original position due to the restoring force of the elastic member 303, and the clamping portion 301c of the plunger body 301 is inserted into the insertion groove of the plunger cap 304, and the inner end of the plunger cap 304 is fixedly placed on the placement portion 301d of the plunger body 301.

[0088] The variable grip handle of the fitness equipment of the present invention constructed as described above is used by being connected to the rope of a fitness equipment such as a rope machine, and when the forearm is in an internal rotation state for movement, the grip part 20 can be horizontally rotated and fixed, and the grip bar 201c can be gripped in the horizontal direction for movement, and when the forearm is in an external rotation state for movement, the grip part 20 can be vertically rotated and fixed, and the grip bar 201c can be gripped in the vertical direction for movement.

[0089] In addition, the grip portion 20 can be set not only horizontally or vertically, but also at various angles, so that when using the fitness equipment for exercise, various parts including the forearm, upper arm, latissimus dorsi, trapezius and rhomboid muscles can be effectively stimulated, thereby maximizing the exercise effect.

[0090] In particular, by fixing the plunger pin 302 of the plunger portion 30 in a state where it is pushed out from the angle adjustment hole 203 of the grip portion 20, the grip portion 20 can be freely rotated. In this way, when exercising by holding the grip rod 201c of the grip portion 20, the grip portion 20 can be freely rotated, and the forearm and upper arm can be internally and externally rotated at the same time during the exercise, thereby expanding the range of movement and contraction of various parts such as the forearm, upper arm, latissimus dorsi, trapezius, rhomboids, etc., and the exercise effect can be maximized by maximizing stimulation.

[0091] In addition, the present invention can be used not only as a fitness device for weight training, but also as a fitness device for physical therapy or rehabilitation exercises, and thus has the advantage of improving the effect of physical therapy or rehabilitation exercises by relaxing muscles or expanding the contraction range.

[0092] The present invention has been described above with respect to limited embodiments, but the scope of the present invention is not limited thereto, and various modifications and improvements implemented by those skilled in the art within the technical concept of the present invention and the equivalent scope of the following claims also fall within the scope of the present invention.
