FIGS. 1 to 3 are perspective views illustrating various operating states of a variable exercise apparatus 100 according to the example embodiments, and FIGS. 4 to 6 are plan views illustrating various operating states of the variable exercise apparatus 100 according to the example embodiments.

More specifically, FIG. 1 is a perspective view illustrating the first state of the variable exercise apparatus 100 according to the example embodiment, FIG. 2 is a perspective view illustrating the second state, and FIG. 3 is a perspective view illustrating the third state.

FIG. 4 is a plan view illustrating the first state of the variable exercise apparatus 100 according to the example embodiment of the present disclosure, FIG. 5 is a plan view illustrating the second state, and FIG. 6 is a plan view illustrating the third state.

In explaining the variable exercise apparatus 100 according to the example embodiments, directions may be defined and used to help understanding. For example, the front is a direction facing a user and may indicate a direction toward the lower left side based on the illustrated state of FIG. 1. The rear may indicate a direction opposite to the front. The left direction is a direction parallel to the ground and perpendicular to the front, and may indicate the upper left with respect to the illustrated state of FIG. 1. The right direction may indicate a direction opposite to the left direction. An upward direction is a direction perpendicular to the ground, and may indicate upward based on the illustrated state of FIG. 1. A downward direction may indicate a direction opposite to the upward direction.

The above direction definitions are intended to help the understanding of the present disclosure, and are not absolute. When any one-direction reference is changed, the other direction references may also be changed in response thereto.

Referring to FIGS. 1 to 6, the variable exercise apparatus 100 according to an example embodiment of the present disclosure may include a main body part 110, a first side frame 120 and a second side frame 130.

The main body part 110 according to the example embodiment of the present disclosure may be polygonal prismatic having an internal space. For example, as illustrated in FIGS. 1 to 3 or in FIGS. 4 to 6, the main body part 110 may have a triangular prism shape having a cross section in the form of a right isosceles triangle. The main body part 110 may be arranged such that a portion forming a right angle of the right isosceles triangle is located at the rear. When arranging the variable exercise apparatus 100 in an indoor space, when the rear surface of the main body part 110 is positioned at the edge of the space, the utilization of the space may be maximized.

The main body part 110 according to an example embodiment may have an internal space, so that various parts may be embedded therein, and the main body part 110 may serve as a center of gravity for supporting the variable exercise apparatus 100 by embedding particularly heavy components. For example, inside the main body part 110, a driving part (not illustrated) that generates exercise load may be included. The driving part may include such as a motor, a speed reducer and a pulley for transmitting an exercise load of the driving part, for example. Since the motor, the speed reducer and the pulley are mainly made of metal and have a relatively heavy weight, they may be arranged inside the main body part 110 to serve as a center of gravity.

A camera 170, a mirror 180 and a display 190 may be arranged on the main body part 110 according to an example embodiment. More specifically, the mirror 180 may be arranged on the front side of the main body part 110. A user may recognize his/her movement while looking at the mirror 180 during the exercise process. The mirror 180 according to an example embodiment may be a one-way transparent mirror 180, and the display 190 may be arranged on the rear surface of the mirror. The one-way transparent mirror 180 may indicate a mirror that acts like a transparent glass in one direction, but acts like a mirror in the other direction. Further, the one-way transparent mirror 180 may indicate a mirror formed so that, when a light source is present in one direction, the light source may be recognized even when viewed from the other direction.

For example, the one-way transparent mirror 180 may be installed on the main body part 110 so that a user may see it from the other direction, and the display 190 may be arranged in one direction of the one-way transparent mirror 180. When the display 190 is not in user, the one-way transparent mirror 180 acts the same as a general mirror and thus, it may be utilized as a general mirror. In the case of using the display 190, since there is a light source generated from the display 190, the user may recognize the display 190 beyond the one-way transparent mirror 180. The camera 170 may be arranged on the front surface of the main body part 110 according to the example embodiment, toward the user. The user's exercise situation may be recognized through the camera 170, and feedback on an exercise movement may be provided through the display 190. Alternatively, after storing an image of the user's exercise, the image may be used in various ways, such as displaying the image on the display 190.

The mirror 181 may be arranged on the first side frame 120 and the second side frame 130 according to an example embodiment. For example, in the state illustrated in FIG. 2, a mirror may be arranged on a surface facing the front so that the user's appearance may be viewed from various angles. Further, the mirror 181 installed on the first side frame 120 and the second side frame 130 may be formed in a shape that is narrower at the bottom than at the top so that the shape of the mirror viewed from the front becomes an inverted trapezoid. Through this, by seeing the upper body with a wide range of exercise through a mirror with a large area, the user may easily grasp the state of his or her exercise.

The first side frame 120 and the second side frame 130 according to the example embodiment may be arranged to be accommodated in or drawn from the main body part 110. Referring to FIGS. 4 to 6, the first side frame 120 and the second side frame 130 may be arranged to be symmetrical on both sides with respect to the main body part 110. For example, if the first side frame 120 is arranged on the left side of the main body part 110, the second side frame 130 may be arranged on the right side of the main body part 110. As described above, since the first side frame 120 and the second side frame 130 are substantially the identical component, the description may be focused on the first side frame 120.

The first side frame 120 according to the example embodiment may be accommodated or projected while sliding along the left side of the main body part 110. For example, as illustrated in FIG. 4, the first side frame 120 may be accommodated in the internal space of the main body part 110. This state may be referred to as a first state. From the first state, as illustrated in FIG. 5, the frames may project by sliding along sides forming a right angle to each other in a portion forming an acute angle of an isosceles right triangle. In other words, as illustrated in FIG. 5, the first side frame 120 may project in a diagonal direction from the left side of the front of the main body part 110. This state may be referred to as a second state. Rails may be installed on the main body part 110 and the first side frame 120 to be slidably movable. Alternatively, the movement of the first side frame 120 may be guided according to the shapes of the protrusion and the groove. As described above, a constitution in which the main body part 110 and the first side frame 120 may slide with each other may be applied in various ways.

The first side frame 120 and the second side frame 130 according to another example embodiment may project from the main body part 110 and rotate vertically with respect to the main body part 110. For example, as illustrated in FIG. 6, the first side frame 120 and the second side frame 130 projected from the main body part 110 may rotate to be closer to each other. This state may be referred to as a third state. By rotating the first side frame 120 to be close to the second side frame 130, according to the user's body structure, a first handle 122 of the first side frame 120 and a second handle 132 of the second side frame 130 may be brought closer to each other.

The first side frame 120 according to an example embodiment may include a first handle adjustment pillar 121 and the first handle 122. Similarly, the second side frame 130 may include a second handle adjustment pillar 131 and the second handle 132. However, as described above, components of the first side frame 120 may be mainly described to help the understanding of the present disclosure.

The first handle adjustment pillar 121 according to the example embodiment may include joining holes 127 aligned in a straight line forming equal intervals in the longitudinal direction on the outer peripheral surface. For example, such a joining hole 127 may be referred to as a first row joining hole 127a. Further, the plurality of joining holes 127 aligned in a straight line may be formed on the peripheral surface of the first handle adjustment pillar 121 in the circumferential direction. For example, the first row joining hole 127a to a fourth row joining hole 127d may be arranged at intervals of 90° in the circumferential direction. The first row joining hole 127a and an adjacent second row joining hole 127b or a third row joining hole 127c may be formed to cross each other so as not to be formed at the same height.

FIG. 7 is a view illustrating a state in which the handle of the variable exercise apparatus 100 is fixed according to an example embodiment of the present disclosure. FIG. 8 is a view illustrating the inside of the variable exercise apparatus 100 in a fixed state by cutting the handle according to an example embodiment of the present disclosure.

The first handle 122 according to the example embodiment may include a handle body 123, a handle adjusting part 124, a pulley part 125 and a first gripping part 126. Likewise, the second handle 132 may include a handle body 133, a handle adjusting part 134, a pulley part 135 and a second gripping part 136.

The handle body 123 according to the example embodiment may be inserted into the first handle adjustment pillar 121 in a pipe shape to move vertically along the first handle adjustment pillar 121. The handle adjusting part 124 according to the example embodiment may fix the handle body 123 to the first handle adjustment pillar 121. Specifically, the handle adjusting part 124 may be installed on the handle body 123 to allow a joining protrusion 128 to project toward the first handle adjustment pillar 121 or to be withdrawn. As the joining protrusion 128 projects and is inserted into the joining hole 127 of the first handle adjustment pillar 121, the handle body 123 may be fixed to the first handle adjustment pillar 121. Again, when the joining protrusion 128 is withdrawn by the handle adjusting part 124 and drawn out from the joining hole 127, the handle body 123 may move vertically along the first handle adjustment pillar 121 again. In this way, by adjusting the height of the first handle 122, the user's exercise part may be changed. The pulley part 125 may be arranged on the opposite side of the handle adjusting part 124 with respect to the handle body 123. The first handle 122 may correspond to a portion directly gripped by the user to perform the exercise. The first handle 122 may be connected to a driving part of the main body part 110 through a cable to receive an exercise load. The cable connected to the first handle 122 may be connected to the driving part through the pulley part 125, and the pulley part 125 may continuously and smoothly convert the transmission direction of the exercise load, so that the user may perform various exercise movements.

FIG. 9 is a view illustrating a first fixing part 140 of the variable exercise apparatus 100 according to an example embodiment of the present disclosure, and FIG. 10 is a cross-sectional view taken along A-A.

Regarding the variable exercise apparatus 100 according to the example embodiment, the first side frame 120 projects from the main body part 110, and a user may exercise by manipulating the first handle 122 arranged on the first side frame 120. In this case, the first side frame 120 may be fixed so that the user may stably exercise.

Therefore, in an example embodiment of the present disclosure, arranging the first fixing part 140 may prevent the first side frame 120 from sliding back to the main body part 110. For example, as illustrated in FIGS. 9 and 10, the sliding movement of the first side frame 120 may be prevented by forming a fixing groove 141 on the bottom of the main body part 110, and arranging a latch 143 that slides vertically on the first side frame 120. More specifically, as the latch 143 is inserted into the fixing groove 141, the sliding movement of the first side frame 120 may be prevented. The fixing groove 141 may be formed in the form of an inverted cone, and this shape may facilitate insertion of the latch 143. A plurality of fixing grooves 141 may be formed, and slide movement may be prevented even when the first side frame 120 is rotated.

FIG. 11 is a view illustrating a second fixing part 150 of the variable exercise apparatus 100 according to an example embodiment of the present disclosure.

As described above, after the first side frame 120 according to another example embodiment projects from the main body part 110, the first side frame 120 may rotate about the main body part 110 as an axis in the vertical direction. For example, as illustrated in FIG. 6, the first side frame 120 and the second side frame 130 projecting from the main body part 110 may rotate to approach each other. However, when the first side frame 120 is fixed, the user may stably perform the exercise.

Therefore, in an example of the present disclosure, arranging the second fixing part 150 may prevent the first side frame 120 from rotating. For example, as illustrated in FIG. 11, a material having a high frictional force, such as a rubber material, may be arranged to move up and down by a lever 153. The second fixing part 150 may prevent the rotation of the first side frame 120 through frictional force by pressing a rubber fixing foot 151 toward the floor through the lever 153.

FIG. 12 is a view illustrating a state in which a pull up handle 160 of the variable exercise apparatus 100 is accommodated according to an example embodiment of the present disclosure, and FIG. 13 is a view illustrating a state in which the pull up handle 160 of the variable exercise apparatus 100 is extended according to an example embodiment of the present disclosure.

The pull up handle 160 may be installed on the first side frame 120 and the second side frame 130, respectively, and the pull up handles 160 may be installed at the front ends of the first side frame 120 and the second side frame 130 to rotate in the vertical direction of the main body part 110 as an axis. When the pull up handles 160 are accommodated and the first side frame 120 and the second side frame 130 are accommodated inside the main body part 110 (for example, the first state), the first side frame 120 and the second side frame 130 may not be exposed externally. When the pull up handles 160 are extended and projected, the user may perform an exercise such as a pull-up. Specifically, since the first side frame 120 and the second side frame 130 may rotate to approach or move away from each other, the distance between the pull up handles 160 may also be adjusted.

FIG. 14 is a view illustrating a lower end of the variable exercise apparatus 100 according to an example embodiment of the present disclosure, and illustrating a state in which the first handle 122 is accommodated.

Since the first side frame 120 according to the example embodiment is accommodated by sliding into the main body part 110, it needs to be arranged so as not to interfere with surrounding structures during the slide movement process. Therefore, the first side frame 120 has a seating part on which the first gripping part 126 may be fixedly arranged to prevent interference with surrounding structures when the first side frame 120 is accommodated.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the spirit or scope of the disclosure.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present disclosure should be determined by reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present disclosure are included in the scope of the present disclosure.
