Description

Technology Field

[0001] The present invention relates to a combined hip adduction and abduction exercise machine, and more specifically, to a combined hip adduction and abduction exercise machine that allows both hip adduction exercises to strengthen the inner thigh muscles and hip abduction exercises to strengthen the outer buttocks and outer thigh muscles to be performed using a single exercise machine, while maintaining a uniform resistance load delivered to the user regardless of the direction of exercise and maximizing the convenience of switching exercise modes through the optimization of the load connection method and cam structure. Background Technology

[0002] With increasing interest in health management and body shape correction in modern society, the weight training equipment market is growing exponentially. In particular, lower body exercises are essential for boosting overall metabolism and building basic physical strength; among these, strengthening the adductor and abductor muscles around the hip joint is considered crucial not only for athletes but also for fall prevention and rehabilitation for the general public and the elderly.

[0003] The hip adductor muscles are located on the inner thigh and serve to bring the legs together along the body's midline, while the hip abductor muscles, centered around the gluteus medius and gluteus minimus on the sides of the hips, perform the function of spreading the legs outward.

[0004] In conventional technology, to perform these two exercises, it was typically necessary to provide separate machines dedicated to hip adduction and hip abduction. However, this not only increased the space occupied by the exercise facility but also caused the inconvenience of users having to move to a different machine whenever they changed the exercise area. To solve this, dual-purpose machines capable of performing both adduction and abduction on a single machine were proposed, but conventional dual-purpose machines had several structural limitations.

[0005] In other words, conventional dual-purpose machines generally rely on cable and pulley systems to transmit loads. This method had the inconvenience of requiring the user to get off the machine to manipulate complex pins or manually rotate the direction of the knee pads when switching exercise modes. Additionally, conventional machines use cables in the load section, but there was a chronic problem where the resistance transmitted to the user was not smooth due to irregular changes in tension at the start and end of the exercise or slight slack in the cables.

[0006] In particular, since the muscle contractions of adduction and abduction movements are opposite, mechanical play is prone to occur during the process of switching load transfer pathways, which can lead to the so-called "dead spot" phenomenon where resistance is lost in specific sections.

[0007] Furthermore, from an ergonomic perspective, the points of maximum force exerted by the adductor and abductor muscles are different. However, conventional devices have shown inefficiency by using only fixed-radius pulleys or simple links to provide uniform resistance throughout the entire range of motion, resulting in a mismatch between the muscle force output curve and the machine's resistance curve. This not only reduces the effectiveness of the exercise but also causes excessive stress on the joints, which can lead to injury.

[0008] Therefore, there is an urgent need to develop an intuitive and robust exercise machine that solves these problems through mechanical link structures and cam geometry, while allowing the user to conveniently switch modes from their seated position. Prior art literature

[0010] The present invention was devised to solve the problems of the prior art, and the objective of the present invention is to provide a combined hip adduction and abduction exercise machine that can perform both hip adduction and hip abduction exercises within a single frame structure, thereby minimizing the space occupied while achieving optimal biomechanical resistance in each exercise mode.

[0011] Another objective of the present invention is to provide a hip adduction and abduction combined exercise machine that maximizes user convenience by providing an exercise selection unit that allows the user to immediately select the type of exercise and finely adjust the starting angle of the exercise according to their flexibility simply by operating a plunger while seated on a seat.

[0012] Another objective of the present invention is to provide a hip adduction and abduction combined exercise machine having a load transmission mechanism that can deliver a uniform and smooth resistance to the user by introducing a load connection method composed of first, second, and third link arms and an upper cam and lower cam structure, so that even if the rotation direction of the rotating arm varies inward or outward, the load transmitted from the load part converges into a single rotating body.

[0013] Another objective of the present invention is to provide a hip adduction and abduction combined exercise machine having a highly durable link and cam coupling structure that minimizes noise and vibration generated during exercise and prevents load deviations due to mechanical wear or play even during long-term repeated use. means of solving the problem

Specific details for implementing the invention

[0046] In describing the specific details for implementing the present invention, the description will be based on preferred embodiments.

[0047] However, this does not mean that the present invention is limited to specific embodiments, and should be understood to include all modifications, equivalents, or substitutions that fall within the spirit and scope of the present invention.

[0048] Furthermore, the objectives and effects presented in this invention do not imply that specific embodiments must include all of them or only such effects, and the scope of the invention should not be understood as being limited by them.

[0049] Unless otherwise defined, all terms used in describing the present invention are preferably interpreted as being consistent with their dictionary meanings and the meanings universally understood in the context of the relevant technology by those skilled in the art to which the present invention pertains.

[0050] Hereinafter, an embodiment of a hip adduction and abduction combined exercise machine according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

[0051] A hip adduction and abduction combined exercise machine of the present invention according to one embodiment comprises: a frame part (10) equipped with a seat (101), a backrest (102), and a handle (103) so that a user can sit on it; a rotational exercise part (20) equipped with a pair of rotational arms (201) installed on the frame part (10) by a pair of rotational axes (202) to perform exercise by rotating the rotational arms (201) with the user's lower body movement; an exercise selection part (30) installed on one rotational axis (202) of the rotational exercise part (20) to select either a hip adduction or hip abduction exercise mode and set an exercise start range; a load transmission part (40) that converts the rotational force transmitted from the rotational exercise part (20) into a load and generates uniform resistance regardless of the direction of exercise; and a load part (50) connected to the load transmission part (40) by a wire (502) to provide weight resistance to the user.

[0052] The above frame part (10) includes a base frame that contacts the ground below, a main post that is vertically erected, and a rear frame that supports the load.

[0053] Each frame is constructed by welding or bolting high-strength square or round steel pipes, and the exterior surface is treated with electrostatic powder coating to ensure corrosion resistance and aesthetics.

[0054] In addition, a floor protector made of rubber or urethane material is installed on the lower corner of the frame part (10) to absorb minute vibrations that occur during exercise and prevent damage to the floor surface.

[0055] The seat (101) is formed at the rear center of the frame portion (10) so that a user can sit on it. The seat (101) is positioned so that the rear side is lower than the front side at an angle of 15 degrees to prevent the user from slipping and to firmly fix the pelvis. This incline allows the axis of rotation (202) of the femur to be stably positioned within the hip joint socket, thereby dispersing the compressive force applied to the joint during heavy weight exercises.

[0056] The above backrest (102) is installed on the rear side of the seat (101) and is equipped with an angle adjustment means to enable angle adjustment according to the user's body type.

[0057] The handle (103) is formed on both sides of the seat (101) at the same height and angle as the seat (101), so as to help the user firmly support the upper body by holding the handle (103) with both hands during exercise.

[0058] The above-mentioned rotational movement unit (20) is rotatably installed on the frame unit (10) and is configured to include a rotation axis (202), a rotation arm (201), a first link arm (203), and a knee pad (204) to perform rotational movement according to the user's lower body movement.

[0059] The above rotation shafts (202) are installed in a vertical direction on the frame part (10) in a spaced-apart pair.

[0060] The above-mentioned rotating arms (201) are configured as a pair, with each rotating arm (201) symmetrically installed so as to be rotatable on each of the pair of rotation axes (202). That is, the front end of each rotating arm (201) is rotatably coupled to each rotation axis (202), and the other end of each rotating arm (201) is provided with a footrest (201a) so as to allow both feet to be placed on it.

[0061] The first link arm (203) is preferably connected to the tip portions of the pair of rotation arms (201) such that when one rotation arm (201) rotates, the other rotation arm (201) rotates inwardly or outwardly in synchronization with the same angle, and is connected in an alternating manner with respect to the pair of rotation axes (202) on a plane.

[0062] Accordingly, when one rotating arm (201) rotates at a certain angle, the other rotating arm (201) is immediately rotated in the opposite direction by the same angle through the tension or compression force of the first link arm (203), thereby preventing the user's posture from becoming distorted due to muscle imbalance.

[0063] The knee pad (204) is rotatably installed in the middle of each rotating arm (201).

[0064] Accordingly, the user can rotate the position of the knee pad (204) according to the type of exercise. When performing hip adduction exercises where the legs are spread apart and brought together in a straight line, the knee pad (204) is rotated to be in close contact with the inner knee, and when performing hip abduction exercises where the legs are spread apart and brought together in a straight line, the knee pad (204) is rotated to be in close contact with the inner and outer knees.

[0065] Therefore, since the knee pad (204) is a part that directly transmits force by coming into direct contact with the area around the knee, it is desirable to fill the inside with high-elasticity sponge and wrap the outside with antibacterial treated synthetic leather.

[0066] The above-mentioned exercise selection unit (30) is installed on one side rotation axis (202) of the rotational exercise unit (20) and is configured to include a rotating plate (301), a plunger means (302), and a protruding rod (303) so as to select either a hip adduction or hip abduction exercise mode and set an exercise start range.

[0067] The above-mentioned rotating plate (301) is rotatably installed on one side rotation axis (202) of the rotating motion unit (20), and is preferably positioned below the front end of one side rotation arm (201) of the rotating motion unit (20), and a plurality of input holes (301a) are formed around the rotating plate (301).

[0068] That is, the input holes (301a) are arranged in a fan shape around the perimeter of the rotating plate (301), and the hip adduction zone and hip abduction zone are separated based on the input hole (301a) located in the center among the multiple input holes (301a), thereby allowing the user to immediately switch the type of exercise while sitting on the equipment.

[0069] The plunger means (302) is formed at the tip of one side rotating arm (201) of the rotating motion part (20) and is selectively coupled to one of a plurality of input holes (301a) formed along the circumference of the rotating plate (301).

[0070] Accordingly, the user pulls the lever of the plunger means (302) to release the pin, then spreads or gathers a pair of rotating arms (201) of the rotating movement unit (20) to a desired position, and then releases the lever. As a result, the pin is inserted into a specific insertion hole (301a) of the rotating plate (301), and the rotating arm (201) and the rotating plate (301) are connected as one by the plunger means (302) and move together, thereby allowing the user to select hip adduction and hip abduction exercises while sitting on the device.

[0071] The protruding rod (303) is formed to extend vertically downward from one end of the rotating plate (301), and it is preferable that it be formed as a rod body having a circular cross-section.

[0072] Accordingly, the protruding rod (303) acts as a trigger that moves according to the rotation radius of the rotating plate (301) and generates a load when the rotating plate (301), which rotates together with the rotating arm (201), rotates.

[0073] The load transmission unit (40) is configured to include an upper cam (401), a lower cam (402), a rotating body (405), a second link arm (403), and a third link arm (404) to convert the rotational force transmitted from the rotational motion unit (20) into a load and to generate uniform resistance regardless of the direction of motion.

[0074] The upper cam (401) is installed on one side of the rotation axis (202) of the rotational movement unit (20) and is positioned below the rotation plate (301) of the movement selection unit (30), and an upper catch groove (401a) is formed on one side into which a protruding rod (303) formed on the rotation plate (301) is inserted. It is preferable that the upper catch groove (401a) be formed in a semicircular shape corresponding to the cross-sectional shape of the protruding rod (303).

[0075] The lower cam (402) is installed on one side of the rotation axis (202) of the rotational movement unit (20) and is positioned below the upper cam (401). An upper catch groove (401a) is formed on one side into which a protruding rod (303) formed on the rotation plate (301) of the movement selection unit (30) is inserted, and is formed in the opposite direction to the upper catch groove (401a). It is preferable that the lower catch groove (402a) be formed in a semicircular shape corresponding to the cross-sectional shape of the protruding rod (303).

[0076] Accordingly, when the rotating plate (301) rotates counterclockwise, the protruding rod (303) is inserted into the upper catch groove (401a) of the upper cam (401), causing the upper cam (401) to rotate counterclockwise together with the rotating plate (301), and when the rotating plate (301) rotates clockwise, the protruding rod (303) is inserted into the lower catch groove (402a) of the lower cam (402), causing the lower cam (402) to rotate clockwise together with the rotating plate (301).

[0077] That is, during hip adduction, only the upper cam (401) rotates, and during hip abduction, only the lower cam (402) rotates, so that other cams that are not used remain stationary in a standby position, thereby preventing unnecessary inertia or friction.

[0078] The above-mentioned rotating body (405) is rotatably installed at one end of the frame part (10), and at the other end, a guide roller (405a) is formed to transmit torque to the wire (502) of the load part (50).

[0079] Accordingly, the rotating body (405) converts the linear tensile force transmitted from the upper cam (401) or lower cam (402) into rotational torque and transmits it to the wire (502) through the guide roller (405a).

[0080] The second link arm (403) has a front end connected to the upper cam (401) and a rear end connected to the rotating body (405), thereby transmitting the rotational force of the upper cam (401) to the rotating body (405) in a straight line. The second link arm (403) is connected in a rod end manner with ball joints applied to both ends, thereby absorbing minute angular errors during rotational movement and ensuring smooth movement.

[0081] The third link arm (404) has a front end connected to the lower cam (402) and a rear end connected to the rotating body (405), thereby transmitting the rotational force of the lower cam (402) to the rotating body (405) in a straight line. The third link arm (404) is connected in a rod end manner with ball joints applied to both ends, which absorbs minute angular errors during rotational movement and ensures smooth movement.

[0082] Meanwhile, it is preferable that the end portion of the second link arm (403) and the end portion of the third link arm (404) be connected so as to be positioned vertically at the same location in the plane on the rotating body (405).

[0083] Meanwhile, it is desirable to design the rotation radius and rotation curvature of the upper and lower cams (402) and the rotating body (405) so that the resistance felt by the user throughout the entire range of motion corresponds to the muscle's force output characteristics. That is, by designing the rotation radius and rotation curvature so that the resistance naturally increases at the end of the range of motion where the muscle reaches maximum contraction, the stimulation of the neuromuscular system can be maximized.

[0084] The load member (50) is configured to include a weight (501) and a wire (502) so as to provide an exercise load to the rotational movement member (20) during exercise.

[0085] The above weight (501) is formed in a multi-layered stacked structure in the vertical direction. Each weight (501) is formed in a plate-like or block shape having a unit weight of 5 to 10 kg and is arranged to be able to move up and down along a guide rod.

[0086] A selector rod, to which one end of a wire (502) for transmitting tensile force is connected, passes through the center of the weights (501), and the weights (501) are selectively connected to the selector rod by a selection pin inserted into a connection hole formed on the side of the weight (501), thereby allowing the load of the weights (501) applied to the wire (502) to be adjusted by controlling the connection position of the selection pin.

[0087] One end of the wire (502) is connected to a selector rod, and the other end passes through a guide roller (405a) formed on the rotating body (405) of the load transmission unit (40) and is fixed to one side of the frame unit (10).

[0088] Accordingly, when a user performs a hip adduction or hip abduction exercise by rotating the rotating arm (201) of the rotating motion unit (20), as the rotating body (405) of the load transmission unit (40) rotates due to the rotational force of the rotating motion unit (20), the guide roller (405a) formed at one end of the rotating body (405) pulls the wire (502) to generate tension, thereby causing the selected weight (501) to rise and act as an exercise load for the user.

[0089] Accordingly, users can accurately and stably set the desired weight load with simple operations.

[0090] Although the present invention has been described above with respect to limited embodiments, the scope of the present invention is not limited thereto, and changes and modifications to the present invention are possible by those skilled in the art without departing from the technical spirit and scope of the claims of the present invention, and such changes and modifications should be deemed to fall within the scope of the present invention as equivalents.
