Description

Technical Field

[0001] The present invention relates to a squat machine. Background Art

[0002] Generally, with the improvement of living standards, people pay more attention to health, and many people are using various forms of weight exercise equipment to enhance their physical strength.

[0003] The weight exercise equipment is provided in various forms according to body parts or use purposes, to increase muscle strength. For example, there is a squat machine that can perform squat exercises in order to increase the muscle strength of the user's lower limbs.

[0004] A typical squat exercise strengthens the lower limbs by repeatedly sitting down and standing up while holding a barbell or dumbbell. However, squats using a barbell or dumbbell can cause injuries when the user loses their center of gravity.

[0005] In view of this, a squat machine has recently been developed that can prevent the user from being injured while having the actual squat exercise effect.

[0006] The squat machine may include a basic frame, a moving part that is rotatable relative to the basic frame and that supports a weight part, and a supporting part that is movable and that supports the moving part. Summary of the Invention

[0007] Technical issues

[0008] The present invention provides a squat machine and a method of using the same that can easily operate a support member and minimize movement of the support member during exercise.

[0009] Technical Solution

[0010] According to one embodiment, a squat machine may include:

[0011] Basic framework;

[0012] a moving component, which is rotatable about a first axis relative to the basic frame and can support at least one counterweight component;

[0013] a supporting member rotatable relative to the base frame about a second axis different from the first axis and rotatable between a first position and a second position, wherein the first position is located on a rotation path of the moving member and the moving member can be supported on the rotation path, and the second position is located outside the rotation path of the moving member;

[0014] a handle member configured to be mounted on the moving member and to rotate about a third axis different from the first axis and the second axis, thereby rotating the supporting member to the first position;

[0015] a connecting line connecting the support member and the handle member; and

[0016] A pulley guides the movement of the connecting line.

[0017] The pulley may be provided on the basic frame so that the supporting member is maintained in the second position when the moving member rotates relative to the basic frame.

[0018] When the moving member rotates relative to the base frame in a state where the supporting member is located at the second position, the rotation of the handle member may be limited to 20% or less of a rotatable range.

[0019] The pulley may include a contact portion that contacts the connecting line, and wing portions that are arranged on both sides of the contact portion and prevent the connecting line from shaking, and the distance between the rotation center of the pulley and the center of the first axis may be greater than 1 times and less than 1.5 times the sum of the radius of the wing portion and the radius of the first axis.

[0020] When the moving part rotates relative to the basic frame, the length of the connecting line wound on the pulley may change, and the position of the pulley relative to the basic frame may be determined by considering the change in the length of the connecting line wound on the pulley.

[0021] When the moving part rotates relative to the basic frame, the third axis of the handle part can move relative to the first axis, and during the movement of the third axis, the distance from the pulley to the handle part can change.

[0022] The moving member may include a shoulder support portion configured to contact a user's shoulder, and the handle member may be disposed adjacent to the shoulder support portion.

[0023] The shortest distance between the handle component and the shoulder support portion may be less than or equal to 20 cm.

[0024] When the supporting member is located at the first position, the supporting member may be disposed lower than the moving member.

[0025] The supporting member may include a first supporting portion supporting the moving member at a first height; and a second supporting portion supporting the moving member at a second height lower than the first height.

[0026] The supporting member may include a safety stopper supporting the moving member to prevent the moving member from directly contacting a floor at the second position.

[0027] The support member may be configured to move from the first position to the second position by gravity.

[0028] The supporting member may further include a weight portion providing a load to move from the first position to the second position.

[0029] The squat machine may further include a biasing member provided at at least one end portion of the connecting wire and providing a bias for pulling the connecting wire in one direction.

[0030] The biasing component may include: a fixing portion fixed to one end of the connecting line; a connecting shell for connecting the connecting line to the supporting component or the handle component; and an elastic component providing an elastic force to move the fixing portion away from the connecting shell.

[0031] Other aspects, features, and advantages than those described above will become apparent from the following drawings, claims, and detailed description of the invention.

[0032] These general and specific aspects may be implemented using a system, a method, a computer program, or any combination of the systems, methods, or computer programs.

[0044] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals denote the same components, and the size or thickness of each component may be exaggerated for clarity of explanation.

[0045] Figure 1a and Figure 1b 2 is a perspective view for explaining a squat machine 1 according to an embodiment. Figure 2 is a cross-sectional view of the squat machine 1 of FIG1 , Figures 3 to 6 2 is a cross-sectional view of the squat machine 1 according to the embodiment, and is a diagram for explaining a usage state of the squat machine 1 .

[0046] Reference Figure 1a 、 Figure 1b ,and Figure 2 The squat machine 1 according to the embodiment includes a basic frame 10 , a moving part 20 , a supporting part 30 , and a handle part 40 .

[0047] The base frame 10 is provided on the bottom surface and rotatably supports the moving part 20. The base frame 10 may include a first frame 11 provided on the bottom surface and a second frame 12 provided at a predetermined angle to the first frame 11. The moving part 20 may be mounted on the second frame 12. The angle between the second frame 12 and the first frame 11 may be 45°. to 135 or 90 to 135 .

[0048] The first frame 11 may include a plate 13 that supports the feet of a user performing exercise. The plate 13 may be connected to an adjustment portion 14 that can adjust at least one of height and inclination. However, since the plate 13 and the adjustment portion 14 are optional, they may be omitted as desired.

[0049] The moving member 20 is rotatable relative to the base frame 10 about a first axis 21. The first axis 21 may be located at a predetermined height from the bottom surface. For example, the first axis 21 may be located at a height of 30 cm to 100 cm from the bottom surface. The first axis 21 may be mounted on the second frame 12.

[0050] The moving part 20 includes a pair of support bars 221 capable of supporting at least one weight member 222. A user can set the moving part 20 to a desired weight by inserting a desired number of weight members 222 into the support bars 221.

[0051] The moving member 20 includes a pair of shoulder support portions 23 configured to contact the user's shoulders and a back support portion 24 configured to support the user's back. The shoulder support portions 23 include a first support portion 231 that supports the user's shoulders when the user moves in a first position facing the moving member 20, and a second support portion 232 that supports the user's shoulders when the user moves in a second position facing a direction opposite to the first position.

[0052] The shoulder supporting portion 23 and the back supporting portion 24 may be disposed at a predetermined angle, for example, 60° to 120° or 80° to 100°.

[0053] The user can perform squatting exercises while standing on the board 13 and supporting the shoulders on the shoulder supports 23 .

[0054] The support member 30 can rotate relative to the base frame 10 about a second axis 31. The second axis 31 can be mounted on the first frame 11. The second axis 31 is a different axis from the first axis 21. The rotation center A2 of the second axis 31 can be parallel to the rotation center A1 of the first axis 21, but can also be set at a position lower than the rotation center A1 of the first axis 21.

[0055] The support member 30 can optionally support the moving member 20. For example, the support member 30 can support the moving member 20 to limit the descent of the moving member 20 when the user finishes or stops exercising, or can be separated from the rotation path of the moving member 20 to not limit the rotation of the moving member 20 when the user performs exercise.

[0056] The supporting component 30 can rotate between a first position 301 and a second position 302 , wherein the first position 301 is located on the rotation path of the moving component 20 and can support the moving component 20 , and the second position 302 is located outside the rotation path of the moving component 20 .

[0057] Therefore, when the support member 30 is in the first position 301, the moving member 20 is supported on the support member 30 so that the moving member 20 does not drop to a predetermined height or lower. Therefore, the user can rest or finish the exercise and leave the squat machine 1 while the moving member 20 is supported on the support member 30.

[0058] Reference Figure 3 and Figure 4 When the support member 30 is located at the second position 302, since the support member 30 is outside the rotation path of the moving member 20, the rotation of the moving member 20 is not restricted by the support member 30. Therefore, the user can raise or lower the moving member 20 without interference from the support member 30.

[0059] Reference Figures 2 to 6 The support member 30 may include a plurality of support portions 320 that support the moving member 20 at a first position 301. For example, the support member 30 may include a first support portion 321 that supports the moving member 20 at a first height and a second support portion 322 that supports the moving member 20 at a second height lower than the first height. The first position 301 may be a plurality of positions. For example, the first position 301 may include a 1-1 position 301 in which the moving member 20 contacts and is supported by the first support portion 321, and a 1-2 position 301-2 in which the moving member 20 contacts and is supported by the second support portion 322.

[0060] The support member 30 can be configured to move from a first position 301 to a second position 302 by gravity. The support member 30 includes a first portion 32 having a support portion 320, and a second portion 33 that provides a rotational force in a specified direction when no external force acts on the first portion 32. The second portion 33 of the support member 30 may further include a weight portion 331 that provides a load to enable the support member 30 to move from the first position 301 to the second position 302.

[0061] Refer again Figure 3 When the user lifts the moving part 20, the contact between the moving part 20 and the support part 30 is released, and the support part 30 rotates clockwise around the second axis 31 due to the weight of the second part 33. As a result, the support portion 320 provided on the first part 32 moves to a position that does not interfere with the rotation of the moving part 20.

[0062] Reference Figure 6, the support member 30 may further include a safety stopper 323, which is provided at a position lower than the second support portion 322. When the support member 30 is located at the second position 302, the first support portion 321 and the second support portion 322 of the support member 30 are located outside the rotation path of the moving member 20, whereas the safety stopper 323 is located in the rotation path of the moving member 20. Therefore, even when the support member 30 is located at the second position 302, the safety stopper 323 can support the moving member 20 to prevent the moving member 20 from directly contacting the floor.

[0063] Figure 7 FIG. 1 is a side view of the squat machine 1 according to the embodiment. Figure 8a and Figure 8b 1 is a diagram for explaining the rotation of the support member 30 as the handle member 40 of the squat machine 1 according to the embodiment rotates.

[0064] Reference Figure 1a 、 Figure 1b ,and Figure 7 The handle member 40 is used to operate the support member 30. The handle member 40 is configured to rotate relative to the moving member 20 about a third axis 41 to rotate the support member 30 to the first position 301. The third axis 41 is provided on the moving member 20. By attaching the handle member 40 to the moving member 20, the handle member 40 can be positioned adjacent to the user's shoulder. The shortest distance between the handle member 40 and the shoulder support portion 23 can be less than or equal to 20 cm.

[0065] The handle member 40 is provided at a position adjacent to the user's shoulders, so that the user can operate the handle member 40 while performing a squatting exercise without shaking the center of gravity of the lower limbs.

[0066] Reference Figure 7 、 Figure 8a ,and Figure 8b The handle member 40 can rotate between a third position 401 where the support member 30 is located at the first position 301 and a fourth position 402 where the support member 30 is located at the second position 302 .

[0067] When the user wants to end or temporarily stop exercising, the user can pull the handle component 40 and rotate it to the third position 401 , so that the support component 30 is located at the first position 301 .

[0068] The user can easily visually confirm the positional movement of the support member 30 provided below the moving member 20 while operating the handle member 40 by hand, and thus the moving member 20 can be easily supported on the support member 30 .

[0069] The connection line 50 is provided between the support member 30 and the handle member 40, and transmits a force applied by a user to the handle member 40 to the support member 30. The connection line 50 has a predetermined length.

[0070] The pulley 60 guides the movement of the connection line 50. The direction of the connection line 50 can be converted by the pulley 60. The direction of the connection line 50 connected to the handle part 40 and the direction of the connection line 50 connected to the support part 30 can be changed by the pulley 60.

[0071] When the user moves the handle member 40 from the fourth position 402 to the third position 401 , the force applied by the user is transmitted to the support member 30 through the connection line 50 , and the support member 30 moves from the second position 302 to the first position 301 .

[0072] When the user lifts the moving part 20 without operating the handle part 40, the support part 30 rotates from the first position 301 to the second position 302 due to gravity, and the handle part 40 connected to the support part 30 by the connecting line 50 moves from the third position 401 to the fourth position 402.

[0073] The user performs exercise by repeating the lifting and lowering motions of the moving part 20 while the support part 30 is in the second position 302 .

[0074] Refer again Figure 3 and Figure 4 The moving component 20 can rotate around the first axis 21 between a first moving position 201 and a second moving position 202. The first moving position 201 can be a position where the moving component 20 is at a maximum height, and the second moving position 202 can be a position where the moving component 20 is at a minimum height supported on the safety stop 323.

[0075] Figure 9a and Figure 9b 1 is a diagram for explaining the movement of the handle member 40 caused by the rotation of the moving member 20 of the squat machine 1 according to the embodiment.

[0076] Reference Figure 9a and Figure 9b When the support part 30 is in the second position 302, the moving part 20 repeats the lifting and lowering action within the range between the first moving position 201 and the second moving position 202, the handle part 40 provided on the moving part 20 is lifted and lowered together with the moving part 20.

[0077] When the support member 30 connected to the handle member 40 rotates due to the lifting and lowering of the handle member 40, the movement of the moving member 20 may be inadvertently restricted by the support member 30 or this may cause the user to feel uneasy. When the handle member 40 is inadvertently rotated about the third axis 41 during the process of lifting or lowering the handle member 40, this may also cause the user to feel uneasy.

[0078] In consideration of this, the squat machine 1 according to the embodiment may be configured to prevent or minimize unintended rotation of the support member 30 when the user does not operate the handle member 40 .

[0079] For example, the pulley 60 may be disposed on the base frame 10 such that the support member 30 is maintained in the second position 302 when the moving member 20 rotates relative to the base frame 10 .

[0080] Since the moving part 20 has a structure that rotates around the first axis 21, when the moving part 20 rotates, the third axis 41 of the handle part 40 installed on the moving part 20 also rotates around the first axis 21. When the user exercises, the handle part 40 moves while maintaining a certain distance from the first axis 21.

[0081] The pulley 60 may be provided in the base frame 10 at a position spaced apart from the first shaft 21. When the handle member 40 moves while maintaining a certain distance from the first shaft 21, the distance from the pulley 60 to the handle member 40 changes.

[0082] In the case of a structure in which the support member 30 does not move while the moving member 20 rotates and is located in the second position 302, the length of the connecting wire 50 from the support member 30 to the pulley 60 is constant. On the other hand, the lengths L31 and L32 of the connecting wire 50 wound around the pulley 60 change according to the rotation angle of the moving member 20, and the distances L21 and L22 from the pulley 60 to the handle member 40 also change.

[0083] As described above, when the moving part 20 rotates relative to the base frame 10 , the position of the pulley 60 may be determined in consideration of a change in the length of the connection wire 50 wound around the pulley 60 .

[0084] Figure 10 and Figure 11 2 is a diagram for explaining the arrangement of the pulley 60 according to the embodiment.

[0085] Reference Figure 10 and Figure 11First, in order to reduce the lengths L31 and L32 of the connecting wire 50 wound around the pulley 60, it is possible to consider positioning the pulley 60 closer to the first shaft 21. For example, the center A4 of the pulley 60 may be positioned on the circumference C of an imaginary circle at a certain distance from the rotation center A1 of the first shaft 21.

[0086] In order to minimize the lengths L31 and L32 of the connecting line 50 wrapped around the pulley 60 and make the pulley 60 rotate smoothly, the distance between the rotation center A1 of the first shaft 21 and the center A4 of the pulley 60 can be greater than 1 times the sum of the radius R2 of the pulley 60 and the radius R1 of the first shaft 21 and less than 1.5 times the sum.

[0087] Figure 12 This is a diagram illustrating a pulley 60 according to an embodiment. Figure 12 The pulley 60 includes a contact portion 610 that contacts the connection line 50 and wing portions 620 that are provided on both sides of the contact portion 610 and prevent the connection line 50 from shaking. The radius R2 of the pulley 60 may be the radius of the wing portion 620 of the pulley 60.

[0088] Refer again Figure 9a 、 Figure 9b 、 Figure 10 ,and Figure 11 , the length L1 of the connecting wire 50 from the pulley 60 to the support part 30 is preset, and the lengths L21+L31 and L22+L32 of the connecting wire 50 from the pulley 60 to the support part 30, including the length wound on the pulley 60, are also preset. On the other hand, as the position of the handle part 40 moves as the moving part 20 rotates, the lengths L31 and L32 of the connecting wire 50 wound on the pulley 60 change. For example, the length L31 of the connecting wire 50 wound on the pulley 60 when the moving part 20 reaches the first moving position 201 is less than the length L32 of the connecting wire 50 wound on the pulley 60 when the moving part 20 reaches the second moving position 202. The first moving position 201 may be the position when the moving part 20 is at its highest position, and the second moving position 202 may be the position when the moving part 20 is at its lowest position.

[0089] With this in mind, the pulley 60 can be set at a position where the length L21 of the connecting line 50 from the pulley 60 to the handle part 40 when the moving part 20 reaches the first moving position 201 is greater than the length L22 of the connecting line 50 from the pulley 60 to the handle part 40 when the moving part 20 reaches the second moving position 202.

[0090] For example, the pulley 60 can be set at a position, wherein the difference (= L32 - L31) between the length L31 of the connecting line 50 wrapped around the pulley 60 when the moving part 20 reaches the first moving position 201 and the length L32 of the connecting line 50 wrapped around the pulley 60 when the moving part 20 reaches the second moving position 202 is equal to the difference (= L21 - L22) between the length L21 of the connecting line 50 from the pulley 60 to the handle part 40 when the moving part 20 reaches the first moving position 201 and the length L22 of the connecting line 50 from the pulley 60 to the handle part 40 when the moving part 20 reaches the second moving position 202.

[0091] When the moving member 20 rotates relative to the base frame 10 by setting the position of the pulley 60 as described above, it is possible to reduce the shaking of the handle member 40 and the support member 30. For example, when the moving member 20 rotates relative to the base frame 10, the rotation of the handle member 40 can be limited to 20% or less of the rotatable range.

[0092] On the other hand, even if the position of the pulley 60 is adjusted, the length of the connecting wire 50 from the pulley 60 to the handle member 40 changes as the moving member 20 is raised or lowered due to the difference in distance between the position where the connecting wire 50 is wound around the pulley 60 and the first shaft 21. Accordingly, in the moving member 20 that rotates about the first shaft 21, there is a longest position where the length of the connecting wire 50 from the pulley 60 to the handle member 40 is the longest, and a shortest position where the length of the connecting wire 50 from the pulley 60 to the handle member 40 is the shortest.

[0093] When the squat machine 1 is configured, the connecting wire 50 can be configured to accommodate the movement member 20 in its longest position. However, in the squat machine 1 configured as described above, when the movement member 20 moves to its shortest position, the connecting wire 50 from the pulley 60 to the handle member 40 becomes longer and looser. This can cause the handle member 40 to move, and in severe cases, the connecting wire 50 may become detached from the pulley 60.

[0094] In view of this, the squat machine 1 according to the embodiment may further include a biasing member 70, which is provided at at least one end portion of the connecting wire 50 and provides a bias (or force) for pulling the connecting wire 50 in a direction A to maintain a predetermined tension even if the length of the connecting wire 50 from the pulley 60 to the handle member 40 changes.

[0095] Figure 13 and Figure 14 1 is a diagram for explaining the biasing member 70 of the squat machine 1 according to the embodiment. Figure 13 and Figure 14 An example is shown in which the biasing member 70 is provided on the support member 30 , but the present invention is not limited thereto and the biasing member 70 may also be provided on the handle member 40 .

[0096] Reference Figure 13 and Figure 14 One end of the connection line 50 may be connected to the support member 30 through the biasing member 70 . One end of the connection line 50 may be connected to the second portion 33 of the support member 30 through the biasing member 70 .

[0097] In an embodiment, the biasing member 70 may include a fixing portion 71 fixed to one end of the connecting wire 50 , a connecting housing 72 for connecting the connecting wire 50 to the supporting member 30 , and an elastic member 73 providing elastic force to move the fixing portion 71 away from the connecting housing 72 .

[0098] The connecting housing 72 has an opening 721 through which the connecting wire 50 passes, and is rotatable relative to the second portion 33 of the support member 30. The fixing portion 71 is fixed to the end of the connecting wire 50 and is separated from the opening 721 of the connecting housing 72 by the elastic member 73. The fixing portion 71 can move in the direction A until it contacts the connecting housing 72.

[0099] The connecting wire 50 is pulled by the biasing member 70 in a direction closer to the support member 30. The connecting wire 50 is subjected to tension by the biasing member 70 in a direction closer to the support member 30. Therefore, even when the moving member 200 is in the shortest position, the connecting wire 50 does not become loose but maintains tension. In the above embodiment, an example has been described in which the biasing member 70 is provided at the connection portion between the support member 30 and the connecting wire 50, but the present invention is not limited thereto. The biasing member 70 may be provided at the connection portion between the handle member 40 and the connecting wire 50. In this case, the connecting housing 72 may be used as a component connected to the handle member 40.

[0100] The method of using the squat machine 1 according to the above embodiment will be described.

[0101] 1 , the squat machine 1 according to the embodiment may be in a state where the moving member 20 is supported on the support member 30 in the first position 301. When a user performs a standing motion while supporting their shoulders on the shoulder support portion 23 of the moving member 20, the moving member 20 rises and the contact between the moving member 20 and the support member 30 is released. The support member 30 rotates clockwise to move from the first position 301 to the second position 302.

[0102] When the user repeats the squatting action while supporting the moving part 20, Figure 3 and Figure 4 As shown, the moving part 20 rotates around the first axis 21 and repeats rising and falling. During the rotation of the moving part 20 around the first axis 21, the handle part 40 installed on the moving part 20 rotates while maintaining a certain distance from the first axis 21.

[0103] Even when the handle member 40 is rotated by the pulley 60 spaced apart from the first shaft 21, the support member 30 can be maintained in the second position 302. In other words, when the user exercises, the support member 30 can be maintained in the second position 302 while the moving member 20 rotates relative to the base frame 10.

[0104] When the movable member 20 rotates relative to the base frame 10 while the support member 30 is maintained in the second position 302, the rotation of the handle member 40 is restricted. For example, when the movable member 20 rotates relative to the base frame 10 while the support member 30 is maintained in the second position 302, the rotation of the handle member 40 is restricted to 20% or less of the rotatable range. Here, the rotatable range may be the range in which the handle member 40 rotates from the third position 401 to the fourth position 402.

[0105] When the user finishes the exercise, the user operates the handle 40 to rotate it from the fourth position 402 to the third position 401 around the third axis 41. Since the user operates the handle 40 near the shoulder by hand, the user can rotate the handle 40 while maintaining the balance of the lower limbs.

[0106] By operating the handle member 40, the support member 30, connected via the connection line 50, rotates about the second axis 31 from the second position 302 to the first position 301. To support the moving component 20 on the support member 30, the user can rotate the handle member 40 while confirming the rotation of the support member 30 from the second position 302 to the first position 301. In other words, the user can operate the handle member 40 while visually confirming the rotation of the support member 30 located below the moving component 20. Therefore, the user can easily support the moving component 20 at the desired portion of the first support portion 321 and the second support portion 322 of the support member 30.

[0107] The description thus far has focused on preferred embodiments. Those skilled in the art will appreciate that the invention may be implemented in modified forms without departing from its essential characteristics. Therefore, the disclosed embodiments should be considered illustrative rather than restrictive. The scope of the invention is indicated by the claims, not the foregoing description, and all differences within the scope of equivalents are to be understood as encompassed by the present invention.
