Cross Reference to Related Applications

This application claims priority from korean patent application No. 10-2020 and 0133367, which was filed from korean intellectual property office at 10/15/2020, the disclosure of which is incorporated herein by reference in its entirety.

Technical Field

The invention relates to a hip-raising exercise device.

Background

Generally, the buttocks are portions that make clothes look stylish when trousers or skirts are worn, among body parts. In order to raise the buttocks, buttocks raising exercise is performed.

In other words, hip-up exercise is an exercise program for strengthening the tension of the hip muscles. When the buttocks become more curved by hip-up exercise, even the legs will appear relatively longer.

Representative hip-up exercises include squat, leg-up (meaning that both legs are spread and raised upward, knees and palms are placed on the floor), knees and palms are placed on the floor, locust-type postures, and the like.

Most hip-lifting exercises are free-handed and can be completed without special equipment. Although such bare-handed exercise can exercise the gluteus muscles, i.e., the gluteus muscles, to achieve the effect of lifting the gluteus, there is a problem in that the exercise becomes very difficult because the exercise is performed with the body of the user. Therefore, even a small amount of exercise can easily be exhausted.

To solve this problem, various exercise devices for hip-up exercise have been developed. However, these devices are bulky and expensive, and are not convenient for home use after purchase.

Further, the lever may have a third locking protrusion formed at a middle portion thereof and protruding toward the third rail. A fourth locking protrusion protruding toward the second rail so as to be caught by the third locking protrusion may be formed at one side of the third rail, and a support protrusion protruding toward the second rail may be formed at the other side of the third rail. The third locking protrusion may be caught by one end of the fourth locking protrusion when the second rail is slid into the third rail and one side of the first rail is slid to one side of the third rail, and the third locking protrusion may be rotated to pass through the fourth locking protrusion when the lever is rotated. When the third locking protrusion passes through the fourth locking protrusion, the other side of the first rail may slide toward and thereby be supported by the support protrusion of the third rail; when the rotating lever returns to its original position, the third locking protrusion may be caught by the other end of the fourth locking protrusion, and thus, the first rail, the second rail, and the third rail may be fixed in an overlapped state.

Further, the locking part may have a locking groove into which the first locking protrusion is inserted. When the first rail is unfolded from the second rail, the first rail and the second rail may be fixed in an unfolded state when the first locking protrusion is inserted into the locking groove. When the lever is rotated, the first locking protrusion may be separated from the locking groove and the first and second rails may be slidable as the link member moves in one direction of the first rail while the locking part rotates about the second hinge.

Further, when the first rail is unfolded from one side of the second rail, the locking groove may be inserted into the first locking protrusion and thus fixed to the locking portion, and when the rotating member is simultaneously rotated while being separated from the first rail, the insertion protrusion may be caught by the second locking protrusion and thus fixed, and accordingly, the first rail, the second rail, and the third rail may be fixed in the unfolded state.

Further, the third rail has fifth locking protrusions formed in upper and lower surfaces of one side thereof. The second rail may have sixth locking protrusions protruding from upper and lower sides thereof and protruding between the second locking protrusion and the fifth locking protrusion. When the second rail is slid in one direction, the sixth locking protrusion may be caught by the fifth locking protrusion such that the second rail is not separated from the third rail.

The present invention as described above has the following effects: it is possible to provide a hip-up exercise device which is minimized in size and convenient to store, etc., so that the hip-up exercise device can be conveniently used at home.

Detailed Description

Advantages and features of the present invention and methods of accomplishing the same may be understood more readily by reference to the following detailed description of preferred embodiments and the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the accompanying drawings for illustrating a hip-up exercise device according to an embodiment of the present invention.

Referring to fig. 1 to 6, the hip-up exercise device according to the present invention includes a frame 10, a footboard member 20, a pillar member 30, and a back support member 40.

First, one side of the frame 10 is opened to form the opening 11, and the fixing holes 12 are formed at both sides of the upper surface of the frame 10.

In addition, when the opening 11 is formed, the frame 10 is formed in a "U" shape. In addition, the inward-facing surface of the frame 10 is received to form a receiving groove 13.

The footrest part 20 is disposed in the opening 11 of the frame 10. Such a footboard member 20 includes a footboard 21 supporting a user's foot, and bases 22 provided at both sides of a lower surface of the footboard 21.

The base 22 is arranged to be inserted into the frame 10 through the opening 11 and fixed to the footboard 21. Further, the footboard 21 is formed to be inserted through the opening 11 such that an upper surface of the footboard is parallel to an upper surface of the frame 10.

The column members 30 are provided as a pair of column members, and each column member is inserted and fixed in the fixing hole 12 of the frame 10. In addition, the column member 30 has a rear surface recessed inward, thereby forming a protrusion 31 protruding from a lower portion of the rear surface.

The back support member 40 connects upper portions of the pair of column members 30 and supports the back of the user. That is, the user can move the buttocks up and down while performing the hip-up exercise while the user's feet are supported by the footrest part 20 and the user's back is supported by the back support part 40.

Here, the hip-up exercise device of the present invention can be stored in its minimum volume when not in use.

First, the column member 30 is turned over after being separated from the fixing hole 12, and the protrusion 31 is coupled with the fixing hole 12, so that the rear surface of the column member 30 is coupled and fixed to be connected to the upper surface of the frame 10. Accordingly, the column part 30 and the back support part 40 are folded on the upper surface of the frame 10.

In addition, when the rear surface of the pillar member 30 is coupled to be connected to the upper surface of the frame 10, it is preferable that the lower portion of the pillar member 30 corresponding to the fixing hole 12 is formed such that the protrusion 31 is inserted into the fixing hole 12 and thus fixed in the fixing hole 12, but the present invention is not limited thereto.

The hip-up exercise device according to the present invention further includes a rail member 50.

The rail member 50 is disposed between the receiving groove 13 and the base 22 so that the base can move forward and backward. The structure and operation state of the rail member will be described in detail with reference to fig. 7 to 10.

Meanwhile, a first through hole 32 is formed in the lower portion of the pillar member 30 and the protrusion 31. The first through-hole 32 formed in the pillar member 30 is eccentric toward the front side based on the front and rear sides of the pillar member 30, and the first through-hole 32 formed in the protrusion member 31 is eccentric toward the upper side based on the upper and lower sides of the protrusion 31.

The frame 10 is formed with a second through hole 14, and the second through hole 14 communicates with the first through hole 32 when the lower portion of the pillar member 30 and the protrusion 31 are inserted.

In this case, the hip-up exercise device of the present invention further includes a fixing pin 60.

The fixing pin 60 passes through the first through hole 32 and the second through hole 14 to fix the frame 10 and the column member 30 or the frame 10 and the protrusion 31. In addition, the first through hole 32 and the second through hole 14 are eccentric in the longitudinal direction from the center to one side. Therefore, when the lower portion of the column member 30 is inserted into the fixing hole 12 and erected, the erected state can be fixed by the fixing pin 60.

In the case where the first through hole 32 and the second through hole 14 are each eccentric toward the front, the column member 30 can be stably maintained in a fixed state when the user moves.

For example, when the first through hole 32 and the second through hole 14 are formed at the center, the column member 30 may be rotated about the center. Therefore, in the hip-up exercise, the pillar member 30 can be moved, and the exercise can be performed in an unstable state, thereby causing stretching. Therefore, it is preferable that the first and second through

holes

32 and 14 are eccentric to the front of the frame 10 so that the column member 30 does not rotate.

On the other hand, the hip-up exercise device according to the present invention further includes a connecting member 70 and a ring member 80.

The connecting member 70 connects a pair of the column members 30 and is disposed below the back support member 40. In addition, a lower surface of the connection member 70 is provided so as to be in contact with an upper surface of the frame 10 in a state where the lower portion of the pillar member 30 is inserted into the fixing hole 12. Further, a rear surface of the connection member 70 is provided so as to contact an upper surface of the frame 10 in a state where the protrusion member 31 is inserted into the fixing hole 12.

That is, when the column members 30 are coupled with the fixing holes 12 in an erected or folded state, the lower and rear surfaces of the connection members 70 may be supported by the upper surface of the frame 10, thereby preventing shaking of the pair of column members 30 and increasing the coupling force with respect to the frame 10.

The ring member 80 is provided at the middle of the upper surface of the frame 10, and when the protrusion 31 is inserted into the fixing hole 12 of the frame 10, the ring member 80 is provided at a position contacting the upper surface of the column member 30 so that the band can be fixed.

At this time, when the rear surface of each of the pair of pillar members 30 is coupled to the upper surface of the frame 10, the upper end of each of the pair of pillar members 30 is in contact with the ring member 80 and is inserted and fixed between the ring member 80 and the fixing hole 12. That is, as in the state where the pillar member 30 is folded on the frame 10, when the protrusion member 31 is inserted into the fixing hole 12 such that the rear surface of the pillar member 30 is in contact with the upper surface of the frame 10, the upper end of the pillar member 30 is in contact with the ring member 80, so that the pillar member 30 is fitted between the ring member 80 and the fixing hole 12. In other words, since the upper end of the column member 30 is supported by the ring member 80, the column member 30 can be held in a state of preventing the shake in the front-rear direction.

The above-described rail member 50 will be described in detail below.

Referring to fig. 7 to 10, the rail member 50 includes a first rail 510, a lever 520, a locking member 530, a link member 540, a second rail 550, a rotation member 560, and a third rail 580.

In describing the rail member 50, one side refers to a direction in which the later-described lever 520 is disposed, and the other side refers to a direction in which the later-described support protrusion 583 of the third rail 580 is disposed.

First, the first rail 510 is disposed in the receiving groove. In this case, the first rail 510 may be disposed at a position of a third rail 580 described later.

One end of the lever 520 may rotate together with the first hinge 521 at one side of the first rail 510, and the other end protrudes in one direction of the first rail 510.

That is, the user may hold the lever 520 and rotate it. Here, a spring is also provided, and when the user releases the rotated lever 520, the lever 520 may be returned to its original position by the spring.

The locking member 530 is provided at a middle portion of the first track 510 so as to be rotatable with respect to the second hinge 531.

At this time, the lever 520 and the locking member 530 are disposed at one side of the first rail 510.

The link member 540 connects the lever 520 and the locking part 530 and moves in a rotational direction of the lever 520 when the lever 520 rotates about the first hinge 521.

That is, when the lever 520 rotates, the lever 520 pulls the link member 540 in one direction of the first rail 510. At this time, the connecting member 540 pulls the locking part 530 while moving along the longitudinal direction of the first rail 510.

Further, the pull locking member 530 rotates about the second hinge 531 and is accordingly separated from the first locking protrusion 551 inserted into the locking groove 532, which will be described later. That is, when the locking groove 532 and the first locking protrusion 551 are separated, the first rail 510 may be separated from the second rail 550 and may slide in the other direction of the second rail 550.

The second rail 550 faces the link member 540, and is provided to be slidable in a longitudinal direction of the first rail 510.

In addition, the second rail 550 has a first locking protrusion 551 formed at one side of the second rail 550 to prevent separation from the first rail 510 by being caught by the locking member 530.

In addition, the second rail 550 has a third through hole 552 formed at the other side of the second rail 550 and penetrated by the front and rear sides.

In addition, the second track 550 is shorter than the first track 510. In addition, a third rail 580, which will be described later, is longer than the first rail 510.

Here, one side of the locking groove 532 is formed in a circular shape and the other side thereof is formed in a right angle. That is, when the locking member 530 pulls the first rail 510 in one direction, one side of the locking groove 532 formed in a circular shape is rotated by the first locking protrusion 551 and is coupled and fixed to the first locking protrusion 551, respectively.

At this time, the locking member 530 may further have a spring allowing the first locking protrusion 551 to return to its original position after the first locking protrusion 551 rotates so as to be coupled with the locking groove 532.

The rotating member 560 is disposed at the other side of the second rail 550 so as to be rotatable with respect to the third hinge 561.

In addition, the rotation member 560 is provided with an insertion protrusion 562 which is inserted into the third through hole 552 and protrudes upward and downward, so that the rotation member 560 can rotate by the vertical width of the third through hole 552.

In addition, the middle of the rotation member 560 is formed to have a wider vertical width in a direction from the third hinge 561 toward the end of the other side of the second rail 550, and thus, when the first rail 510 is slid into the second rail 550, the rotation member 560 rotates together with the middle thereof and contacts the other side of the rail 510. At this time, the rotation member 560 is positioned between the upper and lower sides of the first rail 510.

The third rail 580 faces the insertion protrusion 562 of the rotation member 560 and can slide along the longitudinal direction of the second rail 550, and a second locking protrusion 581 is formed at the middle of the third rail 580.

At this time, when the rotation member 560 is separated from the first track 510, the second locking protrusion 581 is caught by the insertion protrusion 562 when the rotation member 560 is rotated. In addition, when the rotation member 560 is positioned between the upper and lower portions of the first rail 510, the second locking protrusion 581 is formed to pass through the insertion protrusion 562.

Accordingly, when the first locking protrusion 551 is fixed to the locking part 530, the rotation member 560 is separated from the first track 510 and rotates. At this time, the insertion protrusion 562 of the rotation member 560 is caught by the second locking protrusion 581.

In addition, when the first locking protrusion 551 and the locking part 530 are separated and the first rail 510 slides in the other direction of the second rail 550, the middle portion of the rotation member 560 is pushed to the other side of the 510, thereby rotating the rotation member 560. When the rotating member 560 is inserted into the first track 510, the insertion protrusions 562 are not caught by the first locking protrusions 551. In addition, the first rail 510 may slide into the second rail 550 when the first locking protrusion 551 passes through the insertion protrusion 562.

The lever 520 has a third locking protrusion 522 formed at the middle portion and protruding toward the third rail 580.

The third rail 580 has a fourth locking protrusion 582 and a support protrusion 583, the fourth locking protrusion 582 being formed at one side and protruding toward the second rail 550 so as to be caught by the third locking protrusion 522; a support protrusion 583 is formed at the other side and protrudes toward the second rail 550.

When the second rail 550 is slid into the third rail 580 and one side of the first rail 510 is slid into one side of the third rail 580, the third locking protrusion 522 is caught by one end of the fourth locking protrusion 582, and when the lever 520 is rotated, the third locking protrusion 522 is rotated to pass through the fourth locking protrusion 582.

At this time, when the third locking protrusion 522 passes through the fourth locking protrusion 582, the other side of the first rail 510 is slid toward the support protrusion 583 of the third rail, thereby being supported by the support protrusion 583.

In addition, when the rotating lever 520 is placed at its original position, the third locking protrusion 522 is caught by the other end of the fourth locking protrusion 582, and thus, the first rail 510, the second rail 550, and the third rail 580 are fixed in an overlapped state.

The locking part 530 has a locking groove 532 into which the first locking protrusion 551 is inserted.

At this time, when the first locking protrusion 551 is inserted into the locking groove 532, the first rail 510 is unfolded from the second rail 550, and the first rail 510 and the second rail 550 are fixed in the unfolded state.

In addition, when the lever 520 is rotated, since the link member 540 is moved in one direction of the first rail 510 and simultaneously the locking part 530 is rotated about the second hinge 531, the first locking protrusion 551 is separated from the locking groove 532. At this time, the first rail 510 and the second rail 550 may slide.

Accordingly, when the first rail 510 is unfolded from one side of the second rail 550, the locking groove 532 is inserted into the first locking protrusion 551 and thus fixed to the locking part 530, and when the rotation member 560 is rotated while being separated from the first rail 510, the insertion protrusion 562 is inserted by the second locking protrusion 581 and thus fixed. Accordingly, the first rail 510, the second rail 550, and the third rail 580 are fixed in the unfolded state.

As described above, when the lever 520 is rotated, the locking groove 532 and the first locking protrusion 551 are separated, and the first rail 510 slides in the other direction of the second rail 550 and overlaps the second rail 550. In addition, the rotating member 560 is separated from the second locking protrusion when rotated by the other side of the first rail, and one side of the second rail 550 is caught by the first hinge 521 and slides in the other direction of the third rail 580 together with the first rail 510 to overlap therewith.

In addition, when the third locking protrusion 522 is caught by one end of the fourth locking protrusion 582, the lever 520 rotates to further slide the first rail 510 in the other direction of the third rail 580. When the lever 520 returns to its original position, the third locking protrusion 522 is caught by the other end of the fourth locking protrusion 582, and thus, the first rail 510, the second rail 550, and the third rail 580 are fixed in an overlapping manner.
