Description

Technical Field

[0001] This invention relates to sports equipment, and more specifically, to sports equipment in which the weight of a counterweight can be adjusted by adjusting the elasticity applied to a metal wire. Background Technology

[0002] Generally speaking, sports equipment refers to equipment used to promote health and train physical fitness. Various forms of sports equipment are used depending on the type of exercise and the body parts that need to be trained.

[0003] The aforementioned exercise equipment can be categorized into aerobic exercises such as treadmills or bicycles, which are used to improve endurance but do not strengthen muscles, and muscle-building exercises, which are used to strengthen muscles.

[0004] Among them, muscle-building exercises train muscles by using specific parts of the body to lift weight blocks of a specified weight.

[0005] In this case, lifting the counterweight does not mean lifting the counterweight directly, but rather lifting the counterweight indirectly by pulling the metal wire connected to the counterweight or by connecting the counterweight to the holding frame and lifting the holding frame.

[0006] However, as mentioned above, muscle-building exercise equipment has the inconvenience of needing to replace or add weights in order to adjust the weight to a suitable weight for the user, and there is a risk of falling accidents when replacing or adding such weights.

[0007] At the same time, with the need for multiple counterweights, it is necessary to ensure adequate space for setting, and it is difficult to easily change the setting position as needed.

[0058] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments described below are merely intended to illustrate the present invention in a manner that enables those skilled in the art to easily implement it, and the scope of protection of the present invention is not limited thereto. Furthermore, in the description of various embodiments of the present invention, structural elements having the same technical features are given the same reference numerals.

[0059] Example

[0060] Figure 1 and Figure 2 This is a perspective view of a sports device according to an embodiment of the present invention. Figure 3 and Figure 4 for Figure 1 and Figure 2 The exploded 3D view of each exercise device is shown.

[0061] In one embodiment of the present invention, the exercise device 100 is used as a device for training muscles. The metal wire 200 extends to both sides of the upper side of the housing 300. Inside the housing 300, there is an elastic module 600 for providing elastic force to the metal wire 200 and an adjustment module 700 for adjusting the elastic force.

[0062] The end of the metal wire 200 extending to the outside of the housing 300 is provided with a handle or other gripping part (not shown), which allows the user to hold or hang a part of the body such as an arm or leg and pull it. When the force is removed after pulling the metal wire 200, the metal wire 200 is reintroduced into the housing 300 by the elastic force provided by the elastic module 600.

[0063] Therefore, users can repeatedly grip the handle and pull the metal wire 200 forcefully, then release it, and repeat the pulling motion to train their muscles. For example, the user stands on the upper side of the housing 300 and pulls the metal wire 200 vertically with both hands. Another example is that the housing 300 is fixed to a wall or vertical support 10 (see reference). Figure 18 After that, pull the metal wire 200 in the front and back direction of your body and move around.

[0064] An embodiment of the exercise device 100 of the present invention includes: a housing 300; a metal wire 200 extending from the inside of the housing 300 to the outside; an elastic module 600 disposed inside the housing 300 for providing elastic force to the metal wire 200; and an adjustment module 700 disposed on one side of the elastic module 600 for adjusting the elastic force applied to the metal wire 200.

[0065] The housing 300 includes a lower housing 400 and an upper housing 500 that can be joined together in an upward and downward direction. As shown in the figure, the housing 300 is generally rectangular elliptical and has a slightly outward protrusion in the middle of one long side. However, this is only one embodiment of the present invention, and the overall appearance of the housing 300 can be appropriately selected as needed.

[0066] The lower housing 400 is a box shape with an open upper part, and a space is formed inside by means of a flexible module 600 and an adjustment module 700. The upper housing 500 is detachably attached to the upper end of the lower housing 400.

[0067] Figure 3 and Figure 4 This is an exploded perspective view of the upper shell.

[0068] like Figure 3 and Figure 4 As shown, the upper housing 500 includes: an upper frame 510, which is attached to the upper end of the lower housing 400; and an upper plate 520, which is attached to the upper side of the upper frame 510. The upper side of the upper frame 510 forms a lower height difference along its perimeter, and the upper plate 520 is inserted into and attached to the upper side of the upper frame 510.

[0069] A first through hole 511 is formed on one side of the center portion of the upper frame 510. Through this first through hole 511 and the second through hole 521 of the upper plate 520 (described later), the module cover 410 (see later) is connected. Figure 5 The upper end of the upper part protrudes towards the upper part of the housing 300. Multiple circular reinforcing ribs 519 are formed on both sides of the first through hole 511 to support the load when a user stands on the upper housing 500. The reinforcing ribs 519 can be combined with the reinforcing ribs 403 of the lower housing to fix the housing position.

[0070] Furthermore, a pair of lead-out portions 513 protrude from both sides of the upper frame 510 along its length. In this case, the upper surface of the lead-out portion 513 can be formed by a curved surface with a central recess, and a lead-out hole 514 for leading out the metal wire 200 is formed through one side of the upper surface of the lead-out portion 513. On the bottom surface of the upper frame 510, a guide roller 515 for guiding the lead-out direction of the metal wire 200 is rotatably provided at the lower part of the lead-out portion 513, so that the metal wire 200 is led out to the outside of the housing 300 through the lead-out hole 514. Furthermore, a mounting hole 512 is formed in the upper frame 510 to fix the position of the base cover 517 of the base portion 516.

[0071] Meanwhile, on the bottom surface of the upper frame 510, a pair of base portions 516 are formed on both sides of the first through hole 511. When a separate bracket is installed on the exercise equipment 100, the base portion 516 is used to connect the bracket and the housing 300. The base portion 516 includes: a base cover 517, which is attached to the bottom surface of the upper frame 510; a connecting rod portion 518, which protrudes to the lower part of the base cover 517 and is attached to the bracket; and an elastic member (not shown), which is disposed inside the base cover 517 for elastically supporting the connecting rod portion 518.

[0072] The connecting rod 518 can be housed inside the housing 300. If the connecting rod 518 is rotated when needed, it can pass through the sixth through hole 450 of the lower housing 400 (see reference) with the aid of the elastic member. Figure 7 It protrudes outward and is integrated into the support.

[0073] The upper plate 520 is attached to the upper side of the upper frame 510. A second through hole 521 is formed on one side of the center portion, communicating with the first through hole 511 of the upper frame 510. Third through holes 522, corresponding to the lead-out portions 513 of the upper frame 510, are formed on both sides in the length direction. When the upper frame 510 is attached to the upper plate 520, the lead-out hole 514 is exposed through the third through hole 522, and the metal wire 200 is led outward through the lead-out hole 514.

[0074] Figure 5 To show from Figure 1 A 3D view of the state after removing the upper shell. Figure 6 for Figure 5 An exploded 3D diagram.

[0075] like Figure 5 and Figure 6 As shown, an elastic module 600 and an adjustment module 700 are provided inside the module cover 410. When the upper shell 500 is combined with the lower shell 400, the upper end of the module cover 410 protrudes to the upper part of the upper shell 500 through the first through hole 511 and the second through hole 521.

[0076] The module housing 410 includes: a lower inner housing 420, which is attached to one side of the bottom surface of the lower housing 400; an upper inner housing 440, which covers the upper part of the lower inner housing 420; and an outer housing 430, the lower end of which is attached around the first through hole 511 of the upper frame 510, and the upper end of which protrudes to the upper part of the upper frame 510 through the first through hole 511. When the upper housing 500 is attached to the lower housing 400, the outer housing 430 surrounds and protects the upper inner housing 440 and the lower inner housing 420. A fifth through hole 433 is also formed in the outer housing 430 to accommodate a cover 432, an adjustment knob 840, and a shaft 810. Furthermore, a fourth through hole 431 is formed on the upper side of the outer cover 430 so that the shaft portion 810 of the rotating component 800 described later can be vertically arranged, and the fourth through hole 431 is connected to the fifth through hole 432.

[0077] Figure 7 This is a side view of the exercise equipment 100. As shown, the lower housing 400 includes: a bottom surface 401, which is in contact with the ground; and an inclined surface 402, which forms a predetermined angle (Θ) with the bottom surface 401. During exercise, the inclined surface 402 helps the user maintain balance and perform correct movements, thereby helping the user learn correct posture. The angle (Θ) formed between the inclined surface 402 and the ground is 10° to 20°. Preferably, it can be about 16°.

[0078] Figure 8 This is a perspective view of the elastic module and the adjustment module. For ease of explanation, the elastic module 600 stored in the side receiving section 421 will be shown without the elastic module 600.

[0079] like Figure 8 As shown, an elastic module 600 and an adjustment module 700 are provided on the lower inner outer cover 420. More specifically, a pair of receiving portions 421 spaced apart from each other are formed inside the lower inner outer cover 420, and each receiving portion 421 houses the elastic module 600. That is, a pair of elastic modules 600 are disposed inside the lower inner outer cover 420 spaced apart from each other, and the adjustment module 700 is disposed between the pair of elastic modules 600.

[0080] On the other hand, guide holes 422 for leading out the metal wire 200 are formed on both sides of the lower end of the lower inner outer cover 420 in a manner that communicates with the receiving portion 421. The other end of the metal wire 200, which is wound around the elastic module 600 at one end, is led out to the outside of the inner outer cover 420 through the guide holes 422, passes through the aforementioned guide roller 515, and extends to the outside of the housing 300 through the lead-out holes 514.

[0081] Figure 9 and Figure 10This is an exploded 3D view of the elastic module.

[0082] The elastic module 600 is used to provide elastic force to the metal wire 200, and includes: a metal wire roller 610 for winding the metal wire 200; a rotating shaft 620 that rotates integrally with the metal wire roller 610; a spring gear 630 that is rotatably disposed on the rotating shaft 620; and a helical spring 660 for providing elastic force to the metal wire 200.

[0083] Reference Figure 9 and Figure 10 The metal wire roller 610 and multiple spring gears 630 are housed in the receiving portion 421 of the lower inner outer cover 420 in a stacked configuration. In this case, the rotating shaft 620 is vertically positioned through the center of the metal wire roller 610 and the multiple spring gears 630, the metal wire roller 610 is coupled in a manner that allows it to rotate integrally with the rotating shaft 620, and the spring gears 630 are coupled in a manner that allows them to rotate freely relative to the rotating shaft 620.

[0084] The spring gear 630 includes: a body 640, which has a housing 641 formed inside and a plurality of gear teeth 642 protruding along the outer peripheral surface; and a cover 650, which is attached to the upper side of the body 640 to cover the housing 641, and a coil spring 660 (also called a "spring spring") is provided in the housing 641 inside the body 640.

[0085] One end of the helical spring 660 is attached to the spring fixing member 670, one end of which is fixedly attached to the rotating shaft 620, and the other end is attached to the inner side of the body 640 of the spring gear 630. Therefore, when the metal wire roller 610 rotates as the metal wire 200 is led out, the rotating shaft 620, which is integrally attached to the metal wire roller 610, will rotate together. When the rotating shaft 620 rotates, the helical spring 660, with one end attached to the rotating shaft 620, undergoes elastic deformation and transmits rotational force to the spring gear 630.

[0086] In this situation, when the rotation of the spring gear 630 is forcibly suppressed, the rotational force of the rotating shaft 620 accumulates in the helical spring 660 and gradually increases the elastic force of the helical spring 660, and the elastic force applied to the metal wire 200 also increases. Therefore, when the force pulling the metal wire 200 is removed, through the elastic force of the helical spring 660, the metal wire roller 610 will rotate in the opposite direction with the rotating shaft 620 and cause the metal wire 200 to be wound around the metal wire roller 610.

[0087] For this purpose, at least one locking protrusion 423 (see reference) is provided along the inner circumferential surface of the receiving part 421. Figure 8 It meshes with at least one of a plurality of spring gears 630 and restricts the rotation of the spring gear 630. For example, as Figure 8As shown, a plurality of locking protrusions 423 can be formed along the inner circumferential surface of the lower end of the receiving portion 421 so as to restrict the rotation of the lowermost spring gear 630 among the plurality of spring gears 630.

[0088] As described above, the spring gear 630, whose rotation is restricted by the locking protrusion 423, provides a basic rotational force that can wind the metal wire 200 around the metal wire roller 610 through the elastic deformation of the helical spring 660. Thus, when the user pulls the metal wire 200, the elastic force will be applied to the metal wire 200.

[0089] like Figure 11 As shown, the upper-side spring gears 631, 632, 633, and 634 include: a gear body 641, one side of which is open to allow the helical spring 660 to be inserted; a cover 650a connected to the gear body in the open-side state, with a radial protrusion 651a formed on the inner surface that contacts the helical spring 660; and a spring retainer 670 fixed to the rotating shaft 620 and fixing the inner end of the helical spring 660. The helical spring 660 is inserted into the spring gear 630, and therefore will contact the upper or lower part of the spring gear 630, thus generating friction. To minimize this friction, a radial protrusion 651a is formed on the bottom surface of the cover 650a. Furthermore, a mating hole 652a for engaging with the gear body 641 is also formed in the cover 650a. A curved groove 671 is formed in the spring retainer 670 to engage with the inner end of the coil spring 660. For ease of use, a pair of curved grooves 671 can be formed on both sides. Spring gears 630, located on the rotating shafts 620 on both sides, are arranged opposite to each other. That is, on one side, the cover 650 is located on the upper side, and on the other side, the cover 650 is located on the lower side. Therefore, for ease of installation of the coil spring 670, a pair of curved grooves 671 can be formed on both sides.

[0090] Figure 12The lower side of the spring gear 635 is shown. As shown, the spring gear 635 includes: a gear body 641, one side of which is open to allow the helical spring 660 to be inserted; a cover 650b connected to the gear body in the open position, with a radial protrusion 651b formed on the inner surface that engages with the helical spring 660; and a spring retainer 670 fixed to the rotating shaft 620 and fixing the inner end of the helical spring 660. Similar to the upper side of the spring gear, a radial protrusion 651b is formed on the bottom surface of the cover 650b to minimize friction with the helical spring 660. A mating hole 652b for engaging with the gear body 641 is also formed on the lower side of the cover 650b. A curved groove 671 is formed on the spring retainer 670 to engage with the inner end of the helical spring 660. For ease of use, a pair of curved grooves 671 can be formed on both sides. The spring gears 630 provided on both sides of the rotating shaft 620 are arranged opposite to each other. That is, on one side, the cover 650 is located on the upper side, and on the other side, the cover 650 is located on the lower side. Therefore, for the convenience of setting the helical spring 670, the bending groove 671 can be formed in pairs on both sides.

[0091] Figure 13 and Figure 14 A metal wire roller 610 is shown. The metal wire roller 610 includes: a shaft hole 613 for fixing the position of a rotating shaft 620 so that the rotating shaft 620 can be inserted and rotated; a connecting rod 612 extending radially from the shaft hole 613; and a winding groove 611 formed annularly on the outer end of the connecting rod 612 for winding the metal wire 200. Figure 14 As shown, the shaft hole portion 613 of the metal wire roller 610 protrudes slightly from the surface of the winding groove portion 611. This is to prevent the metal wire roller 610 from rubbing against the spring gear 630 during use, thus ensuring smooth rotation of the metal wire roller 610.

[0092] In this invention, the adjustment module 700 adjusts the rotational force applied to the rotating shaft 620 and thus the elastic force applied to the metal wire 200 by means of the elastic force of the helical spring 660.

[0093] In existing muscle-building exercise equipment, weights can be added or removed as needed, thereby adjusting the weight for use. However, in the exercise equipment 100 of this invention, the coil springs 660 act as weights. That is, the weight required for muscle-building exercises can be adjusted by increasing or decreasing the number of coil springs 660 that provide elasticity to the metal wire 200 (or the number of spring gears 630 with restricted rotation).

[0094] Reference Figure 2The adjustment module 700 includes a rotating component 800 disposed on one side of the elastic module 600 and a hook component 900 elastically supported toward the rotating component 800. The rotation of the rotating component 800 causes the hook component 900 to move in the back-and-forth direction, thereby locking / unlocking the spring gear 630, thereby adjusting the elastic force applied to the metal wire 200.

[0095] As shown in the figure, the rotating component 800 can be vertically positioned between a pair of elastic modules 600. (Refer to...) Figure 8 The rotating component 800 includes: a shaft portion 810 capable of shaft rotation; a plurality of locking portions 820 whose width extends at predetermined intervals along the height direction of the shaft portion 810; and an adjustment knob 840 formed at the upper end of the shaft portion 810, protruding towards the upper part of the module cover 410. In this case, the plurality of locking portions 820 face the plurality of spring gears 630 and the plurality of hook components 900 described later, respectively, and locking grooves 830 are formed on the outer periphery of the locking portions 820 so that the insertion portions 920 of the hook components 900 described later can be inserted.

[0096] The hook component 900 is provided on one side of the inner outer cover 420. In this case, multiple hook components 900 can be provided facing multiple spring gears 630 and multiple locking parts 820.

[0097] As an example, a mounting portion 424 for mounting the hook component 900 can be formed on one side of the inner outer cover 420, and a plurality of sliding space portions 425 are formed in the upward and downward directions of the mounting portion 424 (see reference). Figure 2 The hook component 900 is slidably inserted into each sliding space portion 425 and is elastically supported in the direction of the rotating component 800 and the spring gear 630 by an elastic body 940 such as a disc spring. Furthermore, to prevent the hook component 900 from detaching, a back plate 426 is attached to the rear surface of the mounting portion 424, and multiple guide grooves 427 are formed through the center and both sides of the front surface of the mounting portion 424 (see reference). Figure 8 This causes the insertion portion 920 and the locking protrusion 930 of the hook component 900 (described later) to protrude into the receiving portion 421.

[0098] Hook component 900 includes: sliding body 910 (see reference) Figure 15 The sliding body 910 is plate-shaped; the insertion part 920 protrudes from the front end of the sliding body 910; the locking protrusion 930 protrudes from both front ends of the sliding body 910 toward the spring gear 630; and the spring and other elastic body (not shown) are used to elastically support the sliding body 910.

[0099] In the hook member 900 installed in the sliding space 425, the insertion part 920 faces the locking part 820 of the rotating member 800, and the locking protrusion 930 faces the spring gear 630. When the locking protrusion 930 engages with the gear teeth 642 of the spring gear 630 by means of the sliding of the hook member 900, the rotation of the spring gear 630 is restricted. When the rotating shaft 620 is rotated due to the lead-out metal wire 200, the helical spring 660 inside the spring gear 630 will accumulate elastic force.

[0100] Therefore, the user can adjust the elastic force applied to the metal wire 200 by increasing or decreasing the number of spring gears 630 that restrict rotation via the hook component 900. That is, as the number of spring gears 630 that restrict rotation via the hook component 900 increases, the number of helical springs 660 that elastically deform due to the rotation of the metal wire roller 610 and the rotating shaft 620 will increase, and the elastic force applied to the metal wire 200 from the helical springs 660 via the rotating shaft 620 will also increase, thus exhibiting the same effect as increasing the counterweight by adding counterweights in the conventional way.

[0101] Figure 15 and Figure 16 This is a diagram showing the working status of the adjustment module.

[0102] The user can adjust the elastic force applied to the metal wire 200 by rotating the rotating component 800. For example, Figure 15 As shown, when multiple hook components 900 are separated from the spring gear 630, only the coil spring 660 of the spring gear 630 (e.g., the lowermost spring gear 630), whose rotation is restricted by the locking protrusion 423, provides elastic force to the metal wire 200.

[0103] Among them, such as Figure 16 As shown, when the rotating component 800 is rotated in one direction, the hook component 900 moves forward toward the rotating component 800 due to the elastic force of the elastic body 940, thereby inserting the insertion part 920 of the hook component 900 into the locking groove 830 of the locking part 820.

[0104] In this case, the locking protrusion 930 of the hook member 900 engages with the gear teeth 642 of the spring gear 630, thereby restricting the rotation of the spring gear 630 and increasing the number of coil springs 660 that provide elastic force to the metal wire 200. That is, in addition to the coil springs 660 of the spring gear 630 (e.g., the lowermost spring gear 630) whose rotation is restricted by the existing locking protrusion 423, the coil springs 660 of the spring gear 630 (e.g., the uppermost spring gear 630) whose rotation is restricted by the hook member 900 also apply elastic force to the metal wire 200.

[0105] Multiple spring gears 630 are stacked along the rotation axis 620 in the receiving portion 421 of the lower inner outer cover 420. Hereinafter, the spring gears 630 from the uppermost layer are referred to as the first spring gear 631 (see reference). Figure 9 The system includes a second spring gear 632, a third spring gear 633, a fourth spring gear 634, and a fifth spring gear 635. The lowest spring gear 630, which is locked in place by the locking protrusion 423 and restricts rotation, may correspond to the fifth spring gear 635. A metal wire roller 610 may be formed between the fourth spring gear 634 and the fifth spring gear 635.

[0106] Furthermore, the multiple hook components 900 are sequentially divided into the first hook component 901 from the uppermost hook component 900 (see reference). Figure 2 The first hook component 901, the second hook component 902, the third hook component 903, and the fourth hook component 904 are respectively positioned opposite the first spring gear 631 to the fourth spring gear 634. The rotation of the rotating component 800 sequentially restricts the rotation of the first spring gear 631 to the fourth spring gear 634 and increases the elastic force applied to the metal wire 200. (Refer to the following...) Figure 13 , and will be explained in detail.

[0107] Figure 17 This is a top view of the rotating components of the adjustment module.

[0108] like Figure 17 As shown, locking grooves 830 are formed in multiple locking portions 820 respectively. Hereinafter, the uppermost locking portion 820 formed on the rotating member 800 will be referred to as the first locking portion 821, and the multiple locking portions below it will be referred to as the second locking portion 822, the third locking portion 823, and the fourth locking portion 824 respectively.

[0109] A total of four locking slots 830 are formed at 45° intervals in the first locking section 821, and a total of three locking slots 830 are formed at 45° intervals in the second locking section 822. The angular interval between adjacent pairs of locking slots 830 can be selected as needed. Furthermore, a total of two locking slots 830 are formed at 45° intervals in the third locking section 823, and a total of one locking slot 830 is formed in the fourth locking section 824.

[0110] In this case, the second locking groove 830 of the first locking part 821 is formed on the same vertical line as the first locking groove 830, and the third locking groove 830 of the first locking part 821 is formed on the same vertical line as the second locking groove 830 of the second locking part 822 and the first locking groove 830 of the third locking part 823. Furthermore, the fourth locking groove 830 of the first locking part 821 is formed on the same vertical line as the third locking groove 830 of the second locking part 822, the second locking groove 830 of the third locking part 823, and the locking groove 830 of the fourth locking part 824.

[0111] That is, with Figure 17 Based on the top view shown, a locking groove 830 for the first locking part 821 is formed at position A, approximately 45° counterclockwise from the contact position O of the insertion part 920 of the hook member 900. At position B, approximately 90° counterclockwise from the contact position O of the insertion part 920 of the hook member 900, locking grooves 830 for the first locking part 821 and the second locking part 822 are overlapped. Furthermore, locking grooves 830 for the first locking part 821, the second locking part 822, and the third locking part 823 are overlapped at position C, approximately 135° counterclockwise from the contact position O of the insertion part 920 of the hook member 900. Finally, locking grooves 830 for the first locking part 821, the second locking part 822, the third locking part 823, and the fourth locking part 824 are overlapped at position D, approximately 180° counterclockwise from the contact position O of the insertion part 920 of the hook member 900.

[0112] The user can operate the adjustment knob 840 and rotate the rotating part 800 as needed. Figure 13 When the rotating component 800 is rotated clockwise by approximately 45°, the first hook component 901 moves towards the rotating component 800 due to the elastic force of the elastic body 940, thereby causing the insertion part 920 to be inserted into the locking groove 830 (position A) of the first locking part 821. In this case, the second hook components 902 to the fourth hook components 904 do not move but maintain their own positions, and the locking protrusion 930 of the first hook component 901 engages with the first spring gear 631 to restrict the rotation of the first spring gear 631.

[0113] Specifically, when the rotating component 800 is rotated approximately 45° clockwise, the insertion portions 920 of the first hook component 901 and the second hook component 902 are inserted into the locking grooves 830 (position B) of the first locking portion 821 and the second locking portion 822. In this case, the third hook component 903 to the fourth hook component 904 will not move but will maintain their positions. The locking protrusions 930 of the first hook component 901 and the second hook component 902 engage with the first spring gear 631 and the second spring gear 632 to restrict the rotation of the first spring gear 631 and the second spring gear 632.

[0114] Subsequently, when the rotating component 800 is rotated further clockwise by approximately 45°, the insertion portions 920 of the first hook components 901 to the third hook components 903 are inserted into the locking slots 830 (position C) of the first locking portions 821 to the third locking portions 823. In this case, the fourth hook component 904 does not move but maintains its own position, and the locking protrusions 930 of the first hook components 901 to the third hook components 903 mesh with the first spring gears 631 to the third spring gears 633 to restrict the rotation of the first spring gears 631 to the third spring gears 633.

[0115] Subsequently, when the rotating component 800 is rotated further clockwise by approximately 45°, the insertion portions 920 of the first hook components 901 to the fourth hook components 904 are inserted into the locking slots 830 (position D) of the first locking portions 821 to the fourth locking portions 824. In this case, the first hook components 901 to the fourth hook components 904 mesh with the first spring gears 631 to the fourth spring gears 634 to restrict the rotation of the first spring gears 631 to the fourth spring gears 634.

[0116] That is, when the rotating component 800 is rotated clockwise in the figure at intervals of approximately 45° each time, the number of spring gears 630 that restrict the rotation by the hook component 900 will increase, thereby increasing the number of helical springs 660 that provide elastic force to the metal wire 200 through the rotating shaft 620, and the elastic force applied to the metal wire 200, i.e., the counterweight weight, will increase.

[0117] On the other hand, after placing the housing 300 of the exercise equipment 100 of an embodiment of the present invention at the bottom, the user can train muscles by pulling the metal wires 200 on both sides while standing on the housing 300.

[0118] Furthermore, as another embodiment, the exercise equipment 100 can also be used by vertically mounting it on a wall or by using a separate vertical support 10. Figure 18 This illustrates the state of the exercise equipment set up on a separate vertical support as described above.

[0119] Figure 19This is a perspective view of the rear side of the exercise equipment 100 mounted on the vertical support 10. As shown, the exercise equipment 100 can be connected to the vertical support 10 via the mounting part 20. The mounting part 20 includes: a front surface connector 27 suspended from a connecting rod portion 518 protruding from the bottom surface of the lower housing 400; a hook connector 26 mounted on the back of the front surface connector 27, suspended from the connecting rod portion 518 and fixed thereon; an intermediate connector 24 connected to the back of the front surface connector 27; a locking connector 23 connected to the lower part of the intermediate connector 24; a back connector 22 connected to the back of the locking connector 23; and a support guide fixing member 21 disposed on the back of the back connector 22 for guiding the vertical support 10 and fixing its position. The locking connector 23 also includes a rod portion 25 for inserting a locking rod 251 into a hole 11 formed in the vertical support 10. Furthermore, the locking rod 251 can be elastically locked and unlocked by a spring 252.

[0120] The embodiments of the present invention have been described above. However, those skilled in the art will understand that various modifications can be made to the present invention without departing from the scope of protection claimed by the present invention.
