Description

Exercise equipment to train the lower body}

The present invention relates to a lower body training device, and more particularly, to perform a squat operation while lying down obliquely, by installing a movable seat equipped with a seat plate and a backrest in which the buttocks and back of a user who steps on an inclined footrest installed on a support frame are closely fixed to an inclined rail installed obliquely on a support frame so as to be movable, thereby enabling lower body exercise while stably fixing the upper body to the movable seat, so that the lower body can be exercised when the lower body is stably fixed in the movable seat, so that the user has a bad back or is not familiar with bare body squats. Of course, it relates to a lower body training device capable of training the lower body by safely increasing the weight during squats.

In general, lower body exercise is a squat that repeats the motion of sitting down and standing up. During squats, a barbell is placed on the shoulders to increase the intensity of the exercise. In the squat movement performed with a barbell placed on the shoulders, the hips fall backward as the upper body naturally leans forward while resistance is applied to the shoulders. As a result, significant resistance is applied to the hips and thighs as well as the waist, and the squat action is possible only when the user can control this resistance by himself.

If the waist is not good due to the resistance during the squat operation as described above, or if the squat operation is not familiar, it is common to get injured because you cannot control the resistance yourself. In order to solve this problem, Utility Model Publication No. 20-2019-0001647 (published on July 1, 2019; squat exercise device) has been proposed.

As shown in FIG. 4, in the prior art, a footrest 400 is installed at the lower end of the support 300 obliquely installed on the bottom surface of the frames 100 and 200, and by sliding along the support 300, a sliding module 500 equipped with a backrest cushion 510 on which the user leans his back is installed, and a shoulder rest 530 is provided at the upper end of the sliding module 500. Through this configuration, the user presses his back against the shoulder rest 530 and the back cushion 510 while lying down, and pushes the sliding module 500 with his legs using the footrest 400 as the support 300. The squat action proceeds. Such an exercise device is commonly referred to as a hack squat device. Non-explanatory numeral 600 is a barbell rod capable of adding weight, and a balancing rod 800 capable of setting a minus weight to facilitate the ascent of the sliding module 500, a balancing wire 900 connecting the balancing rod 800 to the sliding module 500, a reinforcing column 700 for supporting the balancing rod 800, and a fixed pulley 1000 are installed.

Domestic Utility Model Publication No. 20-2019-0001647 (published on July 1, 2019) Japanese Registered Utility Model No. 7017326 (Announced on April 26, 1995) US Patent Application Publication No. US2004/0023760 (published on February 5, 2004) US Patent Publication US5827154 (published on October 27, 1998)

In the prior art, it is a nuclear squat exercise device capable of training the lower body through a squat motion in which the user lies obliquely forward, that is, in a standing posture, closes his back to the back cushion, fixes his shoulders to the shoulder rest, and then pushes the sliding module up and down with his legs.

An object of the present invention is to provide a lower body training device for hack squats that allows a user to squat in a sitting position rather than a standing position even though the user assumes an oblique posture, as in the foregoing, as in the prior art, so that the waist resistance is reduced compared to the squat operation in a standing position, and the exercise effect during the squat operation can be concentrated only on the legs.

In addition, an object of the present invention is to provide a lower body training mechanism for hack squat in which the user can select and perform the body shape or exercise intensity by himself by allowing the user to adjust the angle of the backrest of the movable seat on which the user sits.

In order to achieve the above object, the present invention is based on a lower body training mechanism that enables lower body movement while stably fixing the upper body to the movable seat by installing a movable seat equipped with a seat plate and a backrest in which the buttocks and back of a user who has stepped on an inclined footrest installed on a support frame are closely fixed to perform a squat operation while lying down obliquely to an inclined rail installed obliquely on the support frame so as to be movable.

Preferably, one end of the backrest fixing rod on which the backrest is fixedly installed is rotatably coupled to a fixed swiveling bracket installed on the sliding member, and the other end is rotatably coupled to an end of a movable rod that is spaced apart from the fixed rod and rotatably coupled to the sliding member as a swiveling bracket through a connecting bracket through a connecting bracket so that the length of the backrest is rotatably coupled to the sliding member. This inclination adjusting member is further included.

Preferably, the fixed length band is in the shape of a tubular body, one end of which is rotatably coupled to the movable bracket, the other end of the free end is formed through a fixing hole connected to the inner space of the tubular body, and length adjustment holes are formed at predetermined intervals along the longitudinal direction of the movable length rod, one end of which is rotatably coupled to the connecting bracket installed at the other end of the backrest fixing bracket, and the other end is accommodated into the inner space through an opening at the other end of the fixed length rod through the fixing hole. A length between the fixed length band and the moving length band may be adjusted through a fixing means coupled to one length adjusting ball.

Preferably, on the upper surface of the inclined connection frame installed on the support frame so as to be spaced apart from the bottom surface of the sliding member, a fixing hook formed by protruding and bending is provided at a predetermined interval between the guide space so that a fixing groove is provided to the lower side of the hooking wing facing the rear, and the hook formed at one end of the rod shape and the operating handle bent at the other end are integrally rotated by their own weight to move the hook upward. The locking member moved downward to the one guide space by upward rotation is accommodated in the fixing groove of the one fixing hanger and engaged with the locking wing at the same time, so that the movable seat is fixed in position on the inclined rail, and as the user sitting on the seat member pushes the mobile seat up, the locking member moves from the one fixing groove to the one guide space, and at the same time, through the downward rotation of the operating handle operating under its own weight, the locking member and the locking wing are released. A seat position adjusting member enabling a squat operation may be further included.

In the present invention having the above configuration, a movable seat equipped with a seat plate and a backrest, in which the buttocks and back of a user who has stepped on an inclined footrest installed on a support frame to perform a squat operation while lying down is movably coupled to an inclined rail installed obliquely on the support frame, thereby stably fixing the upper body to the movable seat, thereby enabling lower body movement, safely increasing weight during squatting as well as when the back is not good or the body squat is not familiar It has the advantage of being able to train the lower body.

In addition, the backrest of the movable seat is configured to adjust the angle of the backrest using the backrest inclination adjusting member, so that the user can select and apply the backrest angle to adjust the user's body shape or exercise intensity of the legs and hips.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, since the accompanying drawings show preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. In addition, even if the configuration is essential for carrying out the present invention, a detailed description of the configuration that belongs to the known technology or can be easily implemented by a person skilled in the art from the known technology will be omitted.

As shown in FIGS. 1 to 3, the lower body training device of the present invention is an exercise device capable of performing a hack squat exercise in an oblique sitting position, and includes a support frame 10, an inclined rail 20 inclined to the support frame 10, a seat plate 311, and a backrest 312 to slide the inclined rail 20, and a movable seat 30 provided with a seated on the movable seat 30. It includes an inclined footrest 40 installed on the support frame 10 so that the user can squat with his feet.

The support frame 10 includes a configuration in which a vertical frame 11 on one side and a scaffolding frame on the other side are connected by a connecting frame 13. As shown in FIGS. 1 and 2, the support frame 10 arranges a pair of vertical frames 11 and scaffolding frames 12 connected by one-way connection frames 13a, and a pair of vertical frames 11 and one-way. It can be configured by connecting the frame 13a and / or the scaffolding frame 12 to the other connection frame 13b. Alternatively, the support frame 10 may be configured by connecting the vertical frame 11 having the other connection frame 13b and the scaffolding frame 12 with an inclined connection frame 341a to be described later.

Here, the footrest frame 12 is formed at an upward inclination angle corresponding to the inclination angle of the inclination rail 20 because the user seated in the mobile seat 30 sliding along the incline rail 20 must step while supporting the load during the squat operation. The inclined footrest 40 is fixedly coupled to the footrest frame 12 installed in this way toward the movable seat 30.

The inclined rail 20 is installed on the support frame 10 so as to descend from the top of the vertical frame 11 toward the scaffolding frame 12 . 1 and 2, the inclined rail 20 connects the pair of vertical frames 11 to the other connecting frame 13b and the pair of one-way connecting frames 13a. It can be installed on the other connecting frame 13b. Preferably, the support frame 10 has the other connecting frame 13b connecting the pair of vertical frames 11 to facilitate installation of the inclined rail 20, and the pair of one-way connecting frames 13a. A mounting plate 13c is provided on the connecting frame 13b, and the inclined rail 20 is installed on the mounting plate 13c. Although one inclined rail 20 installed in this way may be installed, it is preferably installed in a pair in parallel.

The movable seat 30 includes a sliding member 32 having a seat member 31 provided with a seat plate 311 and a backrest 312 on the upper surface so that the user can sit obliquely toward the front. It includes a configuration in which it is movably installed along the inclined rail 20.

The sliding member 32 allows the movable seat 30 to move along the inclined rail 20, and may include a connecting plate 322 on which the seat member 31 is installed on an upper surface, and a slide 321 allowing the connecting plate 322 to slide on the inclined rail 20.

The connection plate 322 is a plate body and is disposed in front of the pair of inclined rails 20 . Connection sidewalls 323 may be bent or protruded on both sides of the bottom surface of the connection plate 322, and the slides 321 are coupled to the connection sidewalls 323.

Known techniques for sliding the connecting plate 322 on the inclined rail 20 may be used as the slide 321 . Preferably, the slide 321 has a tubular shape surrounding the circumference of the rod of the inclined rail 20, and is coupled to both connecting side walls 323 of the connecting plate 322 to move the connecting plate 322 along the inclined rail 20.

The seat member 31 is composed of a seat plate 311 fixedly installed on the upper surface of the connection plate 322 and a backrest 312 installed to the rear of the seat plate 311 so that the inclination angle of the backrest 312 can be adjusted.

Adjustment of the inclination angle of the backrest 312 is achieved through the backrest inclination adjusting member 33 .

The backrest inclination adjusting member 33 includes a backrest fixing bar 331 to which the backrest 312 is fixedly coupled, a fixed length bar 332 and a moving length bar 333 installed at the rear of the backrest fixing bar 331 to adjust the inclination angle of the backrest fixing bar 331 by selectively adjusting the insertion length, and the backrest fixing bar 331 and the fixed length bar 332 and the moving length bar ( 333) includes a bracket that rotatably fixes.

The backrest fixing table 331 has a bar shape, and the backrest 312 is fixedly coupled to the front of the bar shape. In addition, one end of both ends in the longitudinal direction is rotatably coupled to a fixed pivoting bracket 334a fixedly installed on the upper surface of the connecting plate 322. A connection bracket 334b is fixedly installed at the other end of the back support 331. Through this configuration, the backrest 312 can rotate in the front and rear directions of the connecting plate 322 around the fixed rotating bracket 334a fixed to the connecting plate 322.

The fixed length bar 332 is formed as a tubular body, and one end in the longitudinal direction of the tubular body is rotatably coupled to a longitudinal rotation bracket 334c fixed to the connecting plate 322 . The other end of the fixed length bar 332 is formed as a free end, and an opening 332b is formed at the end surface of the free end to be connected to the inner space of the tubular body. In addition, a fixing hole 332a connected to the inner space of the tubular body is formed through one side of the free end. Here, the length pivoting bracket 334c is spaced apart from the fixed pivoting bracket 334a and fixedly installed on the upper surface of the connecting plate 322, and accordingly, preferably, the backrest fixing bar 331 and the fixed length bar 332 are also spaced apart from each other in a line on the upper surface of the connecting plate 322.

The moving length band 333 has a rod shape or a tubular shape, and length adjusting holes 333a are formed at predetermined intervals along the longitudinal direction. One end in the longitudinal direction of the moving length bar 333 is rotatably coupled to a connecting bracket 334b coupled to the other end of the backrest fixing bar 331. In addition, the other end of the moving length bar 333 in the longitudinal direction is formed as a free end, and the moving length bar 333 can be inserted into the inner space of the fixed length bar 332 via the opening 332b of the fixed length bar 332 using this free end.

Here, the angle of inclination of the backrest 312 is adjusted according to the degree of insertion of the moving length strip 333 inserted into the fixed length strip 332, and the angle of inclination of the backrest 312 can be fixed through a fixing means 335 that passes through the fixing hole 332a and is coupled to the one length adjusting hole 333a. The fixing means 335 includes a fixing insertion rod 335b inserted into the fixing hole 332a and the length adjusting hole 333a, and a fixing handle 335a coupled to the end of the fixing insert rod 335b and exposed to the outside of the fixing hole 332a.

The backrest inclination adjusting member 33 having the above structure can adjust both lengths to the degree of insertion of the moving length bar 333 inserted into the inner space of the fixed length bar 332, and through this, the inclination angle of the backrest 312 is adjusted. In other words, the user separates the fixing means 335 from the fixed length bar 332 to adjust the angle of the backrest 312, and then pushes or pulls the other end of the moving length bar 333 into the inner space of the fixed length bar 332 and pushes the fixing means 335 into the fixing hole 332a again at a desired position. ) is inserted, and accordingly, the lengths of the fixed length band 332 and the moving length band 333 are fixed. The length adjustment of the fixed length strip 332 and the movable length strip 333 is because one end of the fixed length strip 332 is rotatably coupled to the length movable bracket 334c, and one end of the movable length strip 333 is rotatably coupled to the connection bracket 334b, and one end rotates according to the coupling between the other ends of each length strip, which is a free end. As the lengths of the fixed length bar 332 and the moving length bar 333 are adjusted in this way, the backrest fixing bar 331 to which the backrest 312 is fixed is dependent on the operation of the moving length bar 333 via the connection bracket 334b installed at the other end. For example, as the length of the moving length bar 333 inserted into the fixed length bar 332 increases, one end of the backrest fixing bar 331 rotates backward to the fixed rotating bracket 334a, so that the tilt angle of the backrest 312 increases. Conversely, as the length of the moving length bar 333 inserted into the fixed length bar 332 is shortened, one end of the backrest fixing bar 331 rotates forward on the fixed rotating bracket 334a, so that the tilt angle of the backrest 312 becomes smaller.

Referring to FIG. 3 , the support frame 10 may include a seat fixing adjusting member 34 for fixing the movable seat 30 or sliding it along the inclined rail 20 .

The seat fixing adjustment member 34 includes a fixed hook 341 installed on the support frame 10 and a fixed support 342 installed on the movable seat 30 and selectively engaged or uncoupled with the fixed hook 341.

The fixed hanger 341 is spaced apart from the bottom surface of the sliding member 32 along the inclined rail 20, and an inclined connecting frame 341a is installed on the support frame 10, and a plurality of structures including a hanging wing 341b, a fixing groove 341c and an induction space 341d as one set are installed on the upper surface of the inclined connecting frame 341a at predetermined intervals.

In other words, preferably, the inclined connecting frame 341a is installed between the pair of inclined rails 20, and is spaced apart from the lower surface of the sliding member 32 at the same inclined angle as that of the inclined rails 20. It is fixed to the mounting plate 13c. On the upper surface of the inclined connecting frame 341a installed in this way, the locking wing 341b is protruded from the upper surface of the inclined frame so that the fixing groove 341c is provided to the lower side of the locking wing 341b, and then bent from the top to the rear. In addition, a plurality of hanging wings 341b having such fixing grooves 341c are continuously provided at predetermined intervals on the upper surface of the inclined connection frame 341a with the induction space 341d in between.

The fixing support part 342 is in the form of a rod rotatably installed on the sliding member 32 and operated integrally, and the locking member 342a at one end of the locking wing 341b, which was engaged in the locking operation, escapes the locking wing 341b and at the same time, the locking member 342a and the locking wing 341b are released through the downward rotation of the operating handle 342b at the other end, Squat action is possible.

That is, preferably, the fixing support part 342 has a bar shape bent once as a whole. One end is rotatably installed on the connection sidewall 323 of the connection plate 322 based on the bent portion of the bent bar, and one end of the fixed support portion 342 corresponding to the locking wing 341b is provided with a locking member 342a. In addition, the bent portion of the fixed support portion 342 is configured to be located outside the connection sidewall 323, and is extended so that the user seated on the seat member 31 can stretch out and manipulate it, so that the operating handle 342b is provided. Here, the center of gravity of the fixed support 342 is configured to be biased toward the manipulation handle 342b. This is to maintain the upwardly rotated state of the locking member 342a, which rotates integrally with the operating handle 342b, by rotating the handle 342b having the center of gravity of the fixing support 342 downward when the locking operation of the locking member 342a is released. Through this, while the movable seat 30 slides on the inclined rail 20, the hook 342a does not interfere with the hook 341b, so the user can squat while sitting on the movable seat 30.

Release of the locking operation of the locking member 342a starts when the foot of the user seated on the movable seat 30 pushes the inclined footrest 40 . When the inclined footrest 40 is pushed with the foot, the movable seat 30 starts to move upward. Accordingly, the locking hole 342a of the fixing support part 342, which was accommodated in the fixing groove 341c due to the blocking of the locking wing 341b of the fixing hook 341, escapes the fixing groove 341c and enters the induction space 341d. When the hook 342a enters the induction space 341d, the handle 342b of the fixed support 342 whose center of gravity is biased toward the handle 342b rotates downward, and the hook 342a, which operates integrally with the handle 342b, rotates upward to completely escape the hook 341b. Since the center of gravity of the fixed support 342 is biased toward the manipulation handle 342b, the locking member 342a maintains a state where the locking wing 341b is separated unless an external force operates, and accordingly, the user can perform a squat operation in that state without needing to fix the fixed support 342 separately. At this time, a seat 324 having a cushion so that the locking member 342a is seated on the bottom surface of the connecting plate 322 may be provided on the bottom surface of the sliding member 32 in response to the locking member 342a rotating upward.

Meanwhile, the user who has finished the squat motion extends his hand and rotates the manipulation handle 342b upward. Then, the locking member 342a rotates downward to enter the guide space 341d and is naturally accommodated in the fixing groove 341c as the movable seat 30 moves downward. The locking member 342a accommodated in the fixing groove 341c cannot leave the fixing hook 341 due to the locking wing 341b blocking the upper end of the fixing groove 341c, and thus the movable seat 30 remains fixed on the inclined rail 20.

In the present invention having the above configuration, a weight support member 50 may be further provided to adjust the weight during squat operation. As shown in FIGS. 1 and 2 , the weight holding member 50 is preferably fixed to the upper end of the connection plate 322, and is provided so that a weight disk can be inserted at both ends of the rod shape. In addition, the length rotation bracket 334c of the backrest inclination adjusting member 33 described above may be fixedly installed on the weight supporting member 50, but this is limited to an example, and the length rotation bracket 334c may be directly installed on the connection plate 322.

In addition, as shown in FIGS. 1 and 2, the connection plate 322 may be provided with a support handle 60 for inducing the user seated on the seat member 31 to support the upper body by bringing the hips and back in close contact with the seat plate 311 and the backrest 312 during a squat operation.
