Description

Technical Field

[0001] This invention relates to a method and apparatus for performing exercises suitable for thigh and gluteal muscles, such as those performed on fitness equipment or exercise bikes, by having the user place their arms on their legs in a sitting or lying position and, while pulling their legs toward their chest, perform activities such as lowering or pushing their legs back or pulling or extending their lower limbs, thereby strengthening the thigh and gluteal muscles. Background Technology

[0002] Generally speaking, exercises that strengthen the thigh and gluteal muscles include... Figure 1 As shown, the exercise is performed with the pelvis as the axis, pulling the chest in and then extending the legs outwards. However, the original exercise method and equipment directly transmit the load to the ankles or knees, which can cause damage to the knee and ankle joints. This exercise is not suitable for users with fragile joints.

[0003] Furthermore, the bicycle, a common mode of transportation for knee patients, has evolved into a means of mobility, allowing for rapid riding over long distances with relatively little effort. Therefore, the bicycle's range of motion is as follows: Figure 2 As shown, the rotation axis is near the ankle, and the movement is concentrated in the lower part of the lower limb, with limited movement in the upper part of the lower limb and the hip joint. Therefore, the inventor's existing bicycle has been modified to extend the range of motion to accommodate the range of motion of the hip and knee joints, thereby improving the effectiveness of exercise.

[0004] Specifically, in order to use a bicycle for sports purposes, the inventor's prior art has aligned the arm rotation axis of the original sports device with the hip joint of the body, and arranged it parallel to the hip joint, thereby expanding the range of motion of the hip joint and knee.

[0005] Additionally, by placing the foot pedals or footrests of the fitness equipment connected to the weights on the thigh of the leg being exercised, the user can perform a backward rotation motion of the leg being exercised while sitting, lying down, or standing, thereby reducing the force transmitted to the knee and ankle. Summary of the Invention

[0006] Users with weak knees primarily use their original stationary bikes, such as... Figure 2 As shown, the hip joint has a limited range of motion and its axis of motion is fixed, thus it does not have the effect of exercising the hip joint (range of motion of about 10 to 20 degrees).

[0007] The normal range of motion of the hip joint is as follows: Figure 1 As shown, the range of motion is approximately 120 degrees. Therefore, the inventor's prior art, in order to extend the range of motion, aligns the rotation axis of the motion device parallel to the user's hip joint, allowing the user to perform a downward and backward movement from a starting position with the thighs drawn to the chest. However, the motion device of the invention has several problems. These technical problems are listed below.

[0008] First, in order to align the rotation axis of the arm with the hip joint so that the seat does not obstruct the rotation of the arm, when the number of arm rotation parts is odd, there is a problem that the user needs to change their sitting position before moving (first problem).

[0009] Secondly, for rehabilitation treatment, different ranges of motion for the knee and hip joints are required depending on the location of the injury. For example, for a torn cruciate ligament, the range of motion of the knee is reversed depending on whether the tear is anterior or posterior. Similarly, patients with herniated discs require different ranges of motion for the hip joint depending on its location. However, existing inventions provide a hip joint range of motion of over 120 degrees for normal individuals, which is not suitable for patients with herniated discs, anterior cruciate ligament tears, posterior cruciate ligament tears, etc. (Second problem). Therefore, there is a need for an effective rehabilitation exercise device that can select the range of motion according to the patient's physical condition.

[0010] Third, existing exercise devices have their rotation axis parallel to the hip joint and are equipped with a chair. The user sits on the chair, places their lower limbs on one end of the arm, and performs downward or backward rotation movements while in a chest-tucked position. The length of the arm that allows the body to contact the exercise device varies depending on the rotation angle of the knee or hip joint, causing inconvenience. For example, when raising the leg, the distance from the rotation axis to the pedal shortens; when extending the leg, the distance increases, while the arm length remains fixed, leading to inconvenience and side effects due to excessive knee flexion or extension (the third problem). Therefore, the arm length needs to vary according to the leg length relative to the rotation axis.

[0011] Fourth, in the existing invention, when the foot is placed on the pedal and extended in a straight line, the pedal rotates around the rod as an axis, which causes inconvenience (fourth problem).

[0012] Fifth, the arm of the original bicycle rotates 360 degrees and automatically moves from the end point of the movement to the starting range. However, the arm movement range of the existing invention's motion device is within 180 degrees, thus having the limitation that the arm cannot return from the end point of the movement to the starting range.

[0013] Sixth, in the existing invention's motion device axis changing device, when the roller connected to the resistance body moves from the x-axis parallel to the ground to the y-axis perpendicular to the ground in a hinge manner, the steel cable connected to the roller is not fixed, causing the steel cable to collide with the roller and easily wear out.

[0014] Seventh, the existing motion device is equipped with multiple y-axis rotation devices and bevel gear sets connected to the arm, which have disadvantages such as high manufacturing cost, increased size of gear devices, and susceptibility to failure.

[0015] Eighth, existing exercise devices have the drawback of not being able to perform basic lower limb muscle resistance exercises such as squats, lunges, and deadlifts. Like exercise devices such as total hip exercises designed for thigh and gluteal muscle exercises, existing exercise devices cause the handles to collide with the user's body when performing squats or lunges.

[0016] Ninth, while existing motion devices can perform lower limb movements, they have the drawback of being unable to perform upper body movements.

[0017] Tenth, the existing motion devices have the disadvantage of taking up a lot of space when stored indoors.

[0018] To solve the first problem, the motion device according to the invention is configured such that the arm can slide within the guide range of the guide rail 2, which is positioned between the user's legs when viewed from a top view, so that the seat 4 and the arm do not overlap even if the user does not change the position of the seat 4 or is not provided with two arm rotating parts on each side (KR20-2020-0001877).

[0019] Furthermore, to address the third problem, the motion device according to the present invention is equipped with a shock absorber on an arm connected at one end to a rotating shaft, so that a part of the body connected to the arm extends while rotating. When the leg length changes according to the rotation angle, the shock absorber lengthens the arm and then returns it to its original state. The shock absorber can be in the form of a cylinder, or, in addition to gas, a spring or the like can provide resistance (KR 10-2021-0040066).

[0020] Furthermore, to address the fourth problem, the motion device according to the present invention is equipped with a pipe on the arm and a bar that moves linearly within the pipe, replacing the buffer. This allows a part of the body connected to the arm to extend while rotating. When the leg length changes according to the rotation angle, the arm length is extended by the pipe and the bar that moves linearly within the pipe, and then returns to its original position. Furthermore, a second pipe 22 is provided parallel to the first pipe, and a second bar 21 is provided inside the second pipe. A second bar fixing body 20 is provided on the bar. When the bar moves linearly from inside the pipe to the outside, the second bar also moves linearly from inside the second pipe to the outside, preventing the pedal from rotating about the bar as an axis (KR 10-2021-0046163, 10-2021-0046813). With the above invention, the effect is that not only can rotational force of the lower limbs be performed, but compressional force can also be performed simultaneously.

[0021] Furthermore, in order to solve the fifth problem, the motion device according to the present invention separates the left and right sides of the shaft and uses gears, rollers, etc. to connect the left and right sides motorically so as to automatically return from the end point of the motion to the starting range of the motion (KR 20-2020-0152414).

[0022] Furthermore, to solve the sixth problem, the motion device according to the present invention utilizes a helical gear or a bevel gear to achieve movement along the Z-axis parallel to the ground and rotation along the y-axis perpendicular to the ground. Moreover, the gear device is manufactured in the form of a gearbox so that the user can attach it to an existing motion device, thus reusing the existing device. Furthermore, the timing belt, belt, sprocket, etc., of the original bicycle are inserted into a square or round tube provided under the seat and connected to the gear device according to the present invention. In this way, a belt shaft or sprocket is provided, along with a pulley, for connecting to the resistance body of the original bicycle (KR 10-2020-0152414, KR 10-2020-0153238, KR 10-2020-0170941, 10-2020-0179121, 10-2021-0002955, KR 10-2020-0179121).

[0023] Furthermore, in order to solve the eighth technical problem, the exercise device according to the present invention is equipped with a handle angle adjustment device for adjusting the handle angle of the exercise device, so as to adjust the handle position so that the handle does not touch the user's body during lunges, squats, deadlifts, etc. (KR 10-2021-0058860).

[0024] Furthermore, in order to solve the ninth problem, the motion device according to the invention is equipped in the form of a table and a chair so that it can be used as furniture when not in motion (KR 10-2021-0035113).

[0025] The effects of this invention are listed below.

[0026] First, the exercise device according to the present invention is configured such that even if the user does not change the position of the seat or does not have two arm rotating parts on each side, the user can easily exercise the lower limbs and arm muscles (KR20-2020-0001877).

[0027] Second, the motion device of the present invention combines rotational force and extension force to improve the motion effect and perform movements similar to natural body movements. The rod moves linearly within the tube. When the user sits on a chair and performs the movement of bringing the lower limbs to the chest and then lowering them and rotating them backward, the length of the lower limb body in contact with the arm changes as the hip joint rotates. As a result, the length of the arm increases dynamically and then automatically returns to its original state (KR 10-2021-0040066).

[0028] Third, using rollers, the left and right arms of the motion device rotate motorically, automatically returning from the end of the motion to the starting zone (KR 20-2020-0152414).

[0029] Fourth, by using bevel gears or helical gears, a gear device is provided that allows movement on the Z-axis parallel to the ground or rotation on the y-axis perpendicular to the ground. This solves the problem of wear on the steel cable connected to the roller. By attaching the gear device to an existing bicycle, the resistance of the existing bicycle is utilized, thereby implementing the technology of the existing invention's motion device and allowing the existing bicycle to be reused (KR 10-2020-0152414, KR 10-2020-0153238, KR 10-2020-0163490).

[0030] Fifth, it is equipped with a handle angle adjustment device to adjust the handle position so that the handle does not touch the user's body during lunges, squats, deadlifts, etc. (KR 10-2021-0058860).

[0031] Sixth, the motion device is made in the form of a table and chair so that it can be used as furniture when not in motion (KR 10-2021-0035113).

[0032] As a result, users with weak knees or ankles, or athletes who want to strengthen their thigh and gluteal muscles without adversely affecting their joints, can use this exercise method and device to perform thigh and gluteal muscle strengthening exercises. Strengthening these muscles can, in the long term, help reduce the risk of diabetes, prevent obesity, and improve health in middle age. Additionally, it can help sculpt a more aesthetically pleasing body, improve athletic performance, and avoid negatively impacting the knees and ankles.

[0033] Best practice A sports device, which is a bicycle, an indoor bicycle, or a fitness machine, is characterized by providing a frame 1, a handle 7 connected to the frame, a seat 4 connected to the frame, a rotating shaft 11 connected to the frame 1, an arm 10 connected to the rotating shaft, a tube 12a connected to the arm, and a rod 12b provided for linear movement inside the tube. The user sits or lies on the seat 4, places both legs on the leg supports, alternately raises them towards the chest, rotates and retracts them around the hip joint, and can perform a lowering and backward pushing action from this starting position. Detailed Implementation

[0034] Detailed descriptions of well-known constituent elements that are deemed potentially unnecessarily obscuring the essence of the invention are omitted. The invention can be modified in various ways and can have multiple forms, with embodiments described in detail in the text. However, this is not intended to limit the invention to a specific disclosed form, but rather to include all modifications, equivalents, and substitutions within the scope of the invention's concept and technology. The terminology used in this specification is only for illustrating specific embodiments and is not intended to limit the invention. In this invention, terms such as "comprising" or "having" should be understood to specify the presence of features, numbers, constituent elements, components, or combinations thereof described in the specification, without pre-excluding the presence or additional possibilities of one or more other features or numbers, actions, constituent elements, components, or combinations thereof.

[0035] The following detailed description, with reference to the accompanying drawings, illustrates embodiments of the thigh and gluteal muscle exercises of the present invention for achieving the aforementioned objectives.

[0036] This invention is used to perform exercises suitable for the thigh and gluteal muscles, in order to solve the first problem of the technical subject, such as Figures 3-8As shown (KR 20-2020-0001877), it includes: a frame 1; a seat 4 connected to the frame 1, providing a user with a sitting or lying posture; a guide rail 2 connected to the frame 1; a sliding arm 3 configured to slide within the guide range of the guide rail 2; and a leg support rotatably connected to one end of the sliding arm 3 and positioned across the back or under the user's lower limbs.

[0037] Furthermore, the sliding arm 3 and the guide rail 2 are configured such that the sliding arm 3 moves along the guide rail 2, causing the sliding arm 3 to rotate with its rotation axis positioned at the user's hip joint. The rotation axis of the sliding arm 3, rotating along the guide rail 2, is located at a position corresponding to the user's hip joint. The guide rail 2 is as follows... Figure 5 As shown, when viewed from above, the seat is positioned between the user's legs so that the user can sit or lie on the seat 4, with the user's legs on the leg support, and in a starting position of alternately pulling towards the chest, perform a lowering and pushing-back motion.

[0038] Preferably, to protect the user's knees or ankles, the leg support is positioned behind the user's thighs. Additionally, as... Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, a foot plate or a foot pedal can be connected to one end of the leg support.

[0039] Furthermore, preferential treatment, such as Figure 8 As shown, the guide rail 2 connected to the frame 1 may include an axis transformation section, which transforms the axis into an X-axis rotation direction parallel to the ground. Figure 3 , 4 5) The direction of the y-axis of rotation perpendicular to the ground ( Figure 6 , 7 8) The diagonal direction when the angle with the ground is 45° allows the user to adjust it according to the body part to be moved.

[0040] On the other hand, the guide track 2, as Figure 3 , Figure 4 , Figure 5 As shown, it can be mounted on the frame 1 in a manner that allows for vertical rotation, or as... Figure 6 , Figure 7 , Figure 8 As shown, the axis conversion unit is configured to rotate horizontally and may include a fixing device 6 for fixing the guide rail 2 to the frame 1. Therefore, the user can selectively perform a downward and backward rotational movement from a starting position where the leg is raised towards the chest, or as... Figure 6 As shown, perform the action of opening and then bringing your legs together, or as... Figure 7 As shown, the opening motion is performed from the starting position with the legs together.

[0041] Preferably, the present invention can be connected to a resistance generating body that generates resistance as the sliding arm 3 rotates. The resistance generating body can be constructed using physical friction methods such as magnetic drums or belt tension, fluid resistance devices, or air pressure, circular plates, or counterweight boxes connected to steel cables.

[0042] Furthermore, the motion device according to the present invention addresses a third problem of the aforementioned technical issue, such as... Figures 9 to 12 As shown (KR10-2021-0040066), it is equipped with a frame 1, a handle 7 connected to the frame, a seat 4 connected to the frame, a rotation shaft 11 connected to the frame 1 and positioned parallel to the user's hip joint, an arm 10 connected to the rotation shaft, and a buffer 12 connected to the arm, so that a part of the body connected to the arm can perform a rotational and extending motion, similar to the body's natural movement. The buffer is provided so that its length can be dynamically increased or automatically returned to its original state according to the difference in body length caused by the flexion and extension of the user's knee and hip joints.

[0043] According to conventional techniques, the buffer can internally provide resistance through pneumatic, hydraulic, or spring-like elasticity, shortening and then lengthening, or vice versa. The buffer is preferably integrated with the arm, or, when viewed in the sagittal plane, can be aligned along the same straight line as the arm.

[0044] Furthermore, a resistance body is connected to the rotating shaft to increase the basic resistance to rotational motion. As an embodiment of the present invention, when used in an indoor bicycle, it can expand the bicycle's range of motion and improve the exercise effect.

[0045] Furthermore, in existing motion devices where the arm's rotation axis is parallel to the hip joint or knee, the arm's length remains constant regardless of the angle of rotation of the knee or hip joint, leading to inconvenience. For example, when lifting the leg, the distance from the rotation axis to the pedal shortens, and when lowering the leg, the distance lengthens, but the arm length remains fixed, causing inconvenience and side effects such as excessive bending or extension of the knee. A buffer, on the other hand, allows the arm's length to dynamically lengthen according to differences in body length during bending and extension, and then automatically return to its original position.

[0046] Furthermore, the motion device according to the present invention, such as Figures 9 to 12As shown in (KR 10-2021-0046163), to solve the third problem of the aforementioned technical issue, a frame 1 is provided, a handle 7 connected to the frame, a seat 4 connected to the frame, a rotating shaft 11 connected to the frame 1, an arm 10 rotatably connected to the rotating shaft, a tube 12a arranged in a straight line along the same line as the arm, and a bar arranged in a straight line inside the tube for vertical movement. A pedal is connected to the bar 12a. When the user places their foot on the pedal, raises their leg towards their chest, rotates around the hip joint, and simultaneously retracts and extends their leg. This allows for simultaneous rotational and extension movements, resembling natural body movements. Furthermore, by using the bar to move linearly within the tube, when the user sits in the chair and raises their lower limb to their chest, lowers it, and rotates backward, the arm length can dynamically increase according to the change in the length of the lower limb contacting the arm due to the hip joint rotation, and then automatically return to its original position.

[0047] Through the tube 12a and the rod 12b fitted inside the tube, resistance can be provided internally by means of air pressure, hydraulic pressure, or spring elasticity, according to conventional techniques, allowing the tube to lengthen after shortening, or vice versa. Alternatively, a resistance body can be connected to the rotating shaft to increase the muscle resistance to the rotational movement.

[0048] As one embodiment of the present invention, when used in an indoor bicycle, it can expand the range of motion of the bicycle and improve the exercise effect.

[0049] Furthermore, the motion device according to the present invention addresses the fourth problem of the aforementioned technical issue, such as... Figure 12 As shown in (KR10-2021-0046163), the device comprises: a second tube 22 connected parallel to the tube; a second rod 21 disposed inside the second tube 22; and a second rod fixing body 20 disposed on the rod. When the rod moves linearly from the inside of the tube to the outside, the second rod also moves linearly from the inside of the second tube to the outside, preventing the pedal from rotating about the rod as an axis. Therefore, when the user performs an extension movement from a starting position with their foot on the pedal and closed up, the pedal does not rotate but can move linearly. Furthermore, as... Figure 26 As shown in (KR 10-2021-0046813), optionally, a guide rail 32a may be provided on the tube, and a roller 31a may be provided on the rod, so that the pedal does not rotate about the tube as an axis. Alternatively, a groove may be formed on the rod, or one side of the rod may be cut, and a protrusion may be provided on the tube, so that the pedal does not rotate about the tube as an axis.

[0050] Furthermore, in order to solve the fifth problem of the aforementioned technical issue, the sports device according to the present invention provides a gear device that uses gears and rollers to enable the left and right arms of the sports device to rotate motorically, automatically return from the end of the movement to the starting point, move on an axis parallel to the ground or rotate on an axis perpendicular to the ground; by attaching the gear device to an existing bicycle, the resistance of the existing bicycle can be utilized, thereby enabling the implementation of the sports device technology of the prior art and the reuse of the existing bicycle. Figure 20 , Figure 21 , 25 This is a diagram of a shaft-changing gearbox according to an embodiment of the present invention. Figure 22 , Figure 23 This is a diagram showing how a shaft-changing gearbox according to an embodiment of the present invention is attached to an indoor bicycle.

[0051] Figure 15 , Figure 16 This is a diagram showing a gearbox equipped with gears but without a shaft changing device, as described in another embodiment of the present invention. Figure 10 This is a front view showing how a gearbox is attached to an indoor bicycle according to another embodiment of the present invention.

[0052] Figure 17 , Figure 18 This diagram illustrates a gearbox utilizing steel cables and rollers as a gearbox according to another embodiment of the present invention. Figure 13 , Figure 14 As shown, the gear device is characterized by comprising: a rotating shaft, a horizontal helical gear or bevel gear, a vertical gear or bevel gear 33, a second helical gear or bevel gear 34, an arm 35 connected to 32 and 33, a roller, an elastic belt roller 37, a spur gear or helical gear, a bearing, a y-axis rotation fixing device 30 perpendicular to the ground, and a device 31 fixed to a vertical frame of other moving devices. The description of known technologies is omitted below.

[0053] like Figures 13-14 As shown in (KR 10-2020-0163490), in the shaft changing gear device according to the present invention, the arm can be attached to both the Z-axis parallel to the ground and the y-axis perpendicular to the ground. Figure 25 As shown, in the shaft conversion gear device of the present invention, the y-axis perpendicular to the ground can be configured individually. Figure 13 As shown in 14, it may also include a right through portion that passes through the right x-axis rotation axis, and the upper and lower ends include right arms 32 that pass through the y-axis rotation axis respectively, and a left through portion that passes through the left x-axis rotation axis, and the upper and lower ends include left arms 35 that pass through the y-axis rotation axis respectively. The right x-axis rotation shaft penetrates the right penetration portion and is rotatable, and the left x-axis rotation portion penetrates the left penetration portion and is rotatable.

[0054] The feature is that when the gear device is connected to the lower body exercise device, if the user fixes the rocker arm at a position parallel to the ground, in the starting posture of drawing toward the chest, the user can perform the action of lowering and pushing backward around the hip joint as the axis; if the user fixes the rocker arm at a position perpendicular to the ground, the user's body is in contact with one end of the arm to draw the body in and spread it out.

[0055] As Figure 20 shown, in the axis conversion gear device according to the present invention, the arm can be attached to the x-axis horizontal to the ground, and as Figure 21 , the arm is attached to the y-axis perpendicular to the ground, so that the user can selectively perform the movement of lowering the leg and pushing backward, or the action of drawing toward the middle or spreading out. As Figure 23 shown, the lower limb bracket can be located at 15a below the user's thigh, and as Figure 24 shown, it is located at 15b below the user's lower limb. The lower limb bracket can be as Figure 23 shown, in a "U" shape or in a "L" shape.

[0056] The axis conversion gear device according to the present invention can be attached to a bicycle, and the y-axis perpendicular to the ground can also be configured as a single unit.

[0057] Moreover, (KR 10-2020-0170941) is characterized in that the y-axis rotation device connected to the arm is provided with a planetary gear, so that when the one side arm connected to the y-axis rotation device rotates clockwise, the other side arm rotates counterclockwise.

[0058] Specifically, it is equipped with a sun gear, a planetary gear, and a ring gear. The one side arm connected to the y-axis rotation device and the shaft rod connected to the one side arm are connected to the planetary gear or the ring gear, and the other side arm and the shaft rod connected to the arm are connected to the sun gear, so that the two different arms can rotate in opposite directions.

[0059] Moreover, as Figure 25 shown, in the gear device, a one way bearing 150 or a flywheel or the like may be provided on the y-axis rotation device or the arm, so that when the y-axis rotates in one direction, the arm idles, and when the y-axis rotates in the opposite direction, the arm is fixed to the y-axis and rotates together with the y-axis. Therefore, the two arms are fixed to the y-axis, and will not conflict even if they rotate in opposite directions to each other during rotation. As Figures 19-21As shown, in one embodiment of the present invention, it is characterized by including an x-axis rotation axis, which is aligned in the coaxial direction and spaced apart from each other to form a right side and a left side; a right vertical bevel gear connected to the left side of the right x-axis rotation axis; a left vertical bevel gear connected to the right side of the left x-axis rotation axis; a right horizontal bevel gear connected to the left vertical bevel gear and the right vertical bevel gear; a right y-axis rotation axis configured to be connected to the upper end of the right horizontal bevel gear and perpendicular to the x-axis; a left second vertical bevel gear connected to the left x-axis rotation axis; a left horizontal bevel gear connected to the left second vertical bevel gear; and a left y-axis rotation axis configured to be connected to the upper end of the left horizontal bevel gear and perpendicular to the x-axis. When the right x-axis rotates clockwise, the left x-axis rotates counterclockwise; when the right y-axis rotates clockwise, the left y-axis rotates counterclockwise. Preferably, the system may include a left x-axis arm, one end of which is connected to the left x-axis rotation axis; and a right x-axis arm, one end of which is connected to the right x-axis rotation axis. Additionally, the system may also include a left y-axis arm, one end of which is connected to the left y-axis rotation axis; and a right y-axis arm, one end of which is connected to the right y-axis rotation axis.

[0060] In addition, such as Figures 9 to 12 As shown, the lower limb movement device is characterized by including a seat connected to the frame; a rotation axis positioned corresponding to the seat, allowing the user to sit on the seat and perform vertical rotation of the lower limbs around the hip joint; the rotation axis is coaxially aligned and spaced apart, divided into right and left rotation axes; it also includes a first resistance generator connected to the rotation axis; an arm, one end of which is connected to one end of the rotation axis; and an arm extension section, one end of which is connected to the other end of the arm, the arm extension section being adjustable in length contraction and extension. The arm has a long, extended length; a foot pedal connected to the other end of the extended length; a second resistance generator connected to the extended length; the distance between the foot pedal and the arm is adjusted by adjusting the length of the extended length, the extended length being configured to adjust its strength during extension and retraction; when the user pushes the foot pedal, the arm extends at the instant of pushing the foot pedal, providing resistance to the user's lower limbs; when the user sits on the seat and places their lower limbs on the foot pedal, the user's lower limbs rotate up and down around the hip joint while simultaneously performing the pushing action.

[0061] As another example of the gear device, (KR 10-2021-0002955), the y-axis rotating device is equipped with multiple shafts and arms, and the y-axis rotating device or the spur gear meshes with each other so that when one arm connected to the y-axis rotating device rotates clockwise, the other arm can rotate counterclockwise.

[0062] Furthermore, in order to solve the eighth problem of the aforementioned technical issue, specifically, in order to enable compound lower limb and hip exercises using a single exercise device (KR 10-2021-0058860), a handle angle adjustment device is provided in an exercise device similar to a full hip machine. To this end, the exercise device according to the present invention is configured with an arm, a bar 10a, a handle 7, and a handle angle adjustment device. The arm is configured such that its rotation axis can rotate at a position parallel to the user's hip joint. The bar 10a is connected to the arm 10 and is configured to rotatably cross the user's leg. The handle 7 is arranged parallel to the user's right and left sides. It is also equipped with a weight adjustment device and an arm starting range adjustment device. The handle angle adjustment device adjusts the handle to the same position as a conventional full hip machine when the user performs leg extension and leg retraction / extension movements using the exercise device. When performing squats or lunges, the handle position is adjusted so that the handle does not collide with the user's body.

[0063] Furthermore, the motion device according to the present invention addresses the tenth problem of the aforementioned technical issue, such as... Figures 27-36As shown in (KR 10-2021-0035113), a frame 1 (61) is provided, which consists of a ground support frame 1 (62) arranged parallel to the ground, a horizontal body 1 (63) arranged parallel to the ground support frame 1, and a vertical support frame 1 (64) connecting the ground support frame 1 and the horizontal body 1. Furthermore, a frame 2 (65) connected to the frame 1 is provided.
