Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2024-0038618, filed on March 20, 2024, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present invention relates to a device for assisting muscle strength. Background Art

[0004] Devices for assisting muscle strength, which generate auxiliary power to assist muscle strength (such as those in the human waist muscles), can be broadly divided into two types: so-called rigid devices, which are configured to actively generate force through a power source to generate auxiliary power for assisting muscle strength; and so-called soft devices, which are configured to passively generate auxiliary power in response to changes in the wearer's posture. In these devices, soft devices for assisting muscle strength immediately generate auxiliary power when the wearer's posture changes. Therefore, the advantages of soft devices for assisting muscle strength are that they do not require a separate power source for generating auxiliary power, generate auxiliary power with consistent magnitude and direction in response to changes in the wearer's posture, and have relatively low unevenness caused by the auxiliary power. In contrast, a problem with soft devices for assisting muscle strength is that the magnitude of the auxiliary power is substantially lower than that of rigid devices for assisting muscle strength. Furthermore, a problem with soft devices for assisting muscle strength in related prior art is that the directions in which the auxiliary power is applied are limited, and they are unable to fully generate auxiliary power in all directions in response to various changes in the wearer's posture. For example, conventional waist devices for assisting muscle strength assist the wearer's waist muscles and generate auxiliary power in the direction of waist extension when the wearer bends. However, when the wearer twists the waist, these waist devices for assisting muscle strength cannot generate auxiliary power in the direction opposite to the twisting direction of the waist.

[0005] Therefore, there is a need to develop a device for assisting muscle strength, which can have the advantages of the soft devices for assisting muscle strength in the relevant prior art in a complete manner, generate higher auxiliary power, and generate auxiliary power in various directions in response to various changes in the wearer's posture.

[0051] Hereinafter, an apparatus for assisting muscle strength according to exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0052] Devices for assisting muscle strength

[0053] Figure 1 is a perspective view of the overall structure of a device for assisting muscle strength according to an exemplary embodiment of the present invention; Figure 2 is an enlarged view showing the shapes of two adjacent link components of the apparatus for assisting muscle strength according to an exemplary embodiment of the present invention when viewed from a first side; Figure 3 is an enlarged view showing the shapes of two adjacent link components of the apparatus for assisting muscle strength according to an exemplary embodiment of the present invention when viewed from a second side; Figure 4 is a cross-sectional view illustrating a vertical cross-sectional shape of a link component of an apparatus for assisting muscle strength according to an exemplary embodiment of the present invention.

[0054] The device for assisting muscle strength according to one embodiment of the present invention may be a device for assisting the strength of the wearer's muscles. The device for assisting muscle strength according to an exemplary embodiment of the present invention may be a device for assisting the strength of the wearer's waist muscles. In this case, the device for assisting muscle strength according to one embodiment of the present invention may be a device having the following structure, which is capable of reducing the load applied to the wearer's waist by providing auxiliary power in the direction of waist stretching when the wearer bends forward. In addition, as described below, in a posture in which the wearer is standing while stretching the waist, the device for assisting muscle strength according to one embodiment of the present invention may additionally provide auxiliary power to assist the load applied to the waist, so that the device for assisting muscle strength can provide auxiliary power to the waist even in a posture in which the wearer is moving or standing while holding a heavy object.

[0055] refer to Figures 1 to 4According to one embodiment of the present invention, a device 10 for assisting muscle strength may include a support member 100 including a section extending along a straight line or a curve. If the device 10 for assisting muscle strength according to the present invention is a device for assisting the wearer's waist muscles as described above, the support member 100 may be configured to closely attach to or contact the wearer's waist. Therefore, the support member 100 may have a shape corresponding to the wearer's waist.

[0056] The support member 100 can be configured to deform in accordance with the shape of the wearer's waist. That is, the support member 100 can be made of a material that can be deformed to correspond to the waist condition of the wearer (the person wearing the device 10 for assisting muscle strength). Alternatively, the support member 100 can have a structure that can be deformed to correspond to the waist condition of the wearer. For example, the support member 100 can be made of a material that can be elastically deformed when the support member 100 is bent and twisted by an external force. Alternatively, the support member 100 can be made of a textile fabric material, such as a fabric that can be tightly attached to the wearer's waist and freely deformed in shape according to the waist condition. In this specification, when the wearer wears the device 10 for assisting muscle strength, the front side, back side, side side, upper side and lower side of the wearer are respectively defined as the front side, back side, side side, upper side and lower side of the device 10 for assisting muscle strength.

[0057] The device 10 for assisting muscle strength according to one embodiment of the present invention may include a plurality of link members 200, one side of each link member being fixed to the support member 100. For example, Figure 1 The device 10 for assisting muscle strength is shown in a state where it includes seven link components 200. More specifically, the front area of ​​each of the multiple link components 200 can be fixedly connected to the support component 100, and the multiple link components 200 can be configured to be spaced apart from each other in the vertical direction. Hereinafter, in this specification, the description of the link components 200 of the device 10 for assisting muscle strength according to one embodiment of the present invention will focus on the first link component 200a and the second link component 200b, wherein the first link component is one of the multiple link components 200 and one side of which is fixed to the support component 10, and the second link component is arranged to be closest to the first link component 200a among the multiple link components arranged below the first link component 200a. However, the following description of the first link component 200a, the second link component 200b, and the relationship between the first link component 200a and the second link component 200b also applies to two link components adjacent to each other in the vertical direction and included in the device 10 for assisting muscle strength according to the present invention.

[0058] The plurality of link components 200 provided in the device for assisting muscle strength 10 may each include multiple regions. More specifically, the plurality of link components 200, including the first link component 200a and the second link component 200b, may each include a base region 210 and a protruding region 220 protruding downward from the base region 210. The base region 210 may have a plate shape with a substantially constant thickness in the vertical direction. However, the shape of the base region 210 is not limited to a plate shape. Exemplary detailed shapes of the base region 210 and the protruding region 220 will be described below.

[0059] Continue to refer Figures 1 to 3 , the device 10 for assisting muscle strength according to one embodiment of the present invention may further include a cable component 300 configured to connect the first link component 200a and the second link component 200b. The cable component 300 may be configured to generate auxiliary power for assisting the strength of the wearer's waist muscles by using the tension of the cable. More specifically, the cable component 300 may include a plurality of cables. The length of the cable may vary according to the change in the relative position between two adjacent link components 200. Therefore, the auxiliary power for assisting the strength of the wearer's waist muscles can be generated by the tension of the cable generated by the change in the relative position between the two adjacent link components 200. The plurality of cables included in the cable component 300 may include or be made of a material that can be elastically deformed by an external force.

[0060] The cables of the cable assembly 300 can be distinguished based on the area where two adjacent link members 200 are connected to each other. More specifically, the cable assembly 300 may include a first cable assembly 310, one side of which is connected to the base area 210 of the first link member 200a and the other side of which is connected to the base area 210 of the second link member 200b; and a second cable assembly 320, one side of which is connected to the base area 210 of the second link member 200b and the other side of which is connected to the protruding area 220 of the first link member 200a. The first cable assembly 310 and the second cable assembly 320 may be arranged separately from each other.

[0061] According to one embodiment of the present invention, the first cable member 310 and the second cable member 320 may each include a plurality of cables. More specifically, assuming that the direction in which the first link member 200a and the second link member 200b face the support member 100 is the forward direction, the first cable member 310 may include: a first-first cable 311 configured to connect the front area of ​​the base area 210 of the first link member 200a and the front area of ​​the base area 210 of the second link member 200b; and a first-second cable 312 disposed so as to face the first-first cable 311 with the protruding area 220 of the first link member 200a interposed therebetween.

[0062] The first-first cable 311 and the first-second cable 312 may each be configured to generate tension when the wearer of the device 10 for assisting muscle strength bends forward to generate auxiliary power for assisting the wearer's waist muscles. Figures 1 to 3 When the wearer of the device 10 for assisting muscle strength bends forward, two link members 200 (e.g., the first link member 200a and the second link member 200b) spaced apart from each other and adjacent to each other in the vertical direction move away from each other. Consequently, the first-first cable 311 and the first-second cable 312 connecting the base region 210 of the first link member 200a and the base region 210 of the second link member 200b are stretched. Consequently, tension is applied to the first-first cable 311 and the first-second cable 312, generating assistive force in the direction opposite to the direction in which the two adjacent link members 200 (e.g., the first link member 200a and the second link member 200b) move away from each other (i.e., the direction in which the wearer's waist is stretched). In this specification, the front area of ​​the base area 210 of the link component 200 may be understood as the area located in front of the protruding area of ​​another link component adjacent to the link component 200, and the rear area of ​​the base area 210 of the link component 200 may be understood as the area located behind the protruding area of ​​another link component adjacent to the link component 200.

[0063] like Figures 1 to 3 As shown, in a state where the wearer is standing while wearing the device 10 for assisting muscle strength, the angle of each of the first-first cable 311 and the first-second cable 312 with respect to the up-down direction may be smaller than the angle of each of the first-first cable 311 and the first-second cable 312 with respect to the horizontal direction, and the angle of each of the second-first cable 321 and the second-second cable 322 with respect to the up-down direction may be larger than the angle of each of the second-first cable 321 and the second-second cable 322 with respect to the horizontal direction. This configuration can be understood as a configuration in which the first-first cable 311 and the first-second cable 312 are substantially parallel to the up-down direction or extend close to the up-down direction, while the second-first cable 321 and the second-second cable 322 are substantially parallel to the horizontal direction or extend close to the horizontal direction. Therefore, according to one embodiment of the present invention, the first cable component 310 including the first-first cable 311 and the first-second cable 312 can generate tension in a direction parallel to or close to the up-down direction, while the second cable component 320 including the second-first cable 321 and the second-second cable 322 can generate tension in a direction parallel to or close to the horizontal direction.

[0064] The second cable member 320 may include a second-first cable 321 configured to connect the protruding region 220 of the first link member 200a and the portion of the base region 210 of the second link member 200b located forward of the protruding region 220 of the first link member 200a, and a second-second cable 322 configured to connect the protruding region 220 of the first link member 200a and the portion of the base region 210 of the second link member 200b located rearward of the protruding region 220 of the first link member 200a. More specifically, the second cable member 320 may be provided on the left and right regions of the first cable member 310, respectively.

[0065] Similar to the first-first cable 311 and the first-second cable 312, the second-first cable 321 can be configured to generate tension when the wearer of the device 10 for assisting muscle strength bends forward. Figures 1 to 3 When the wearer of the device 10 for assisting muscle strength bends forward, the distance between the front area of ​​the base area 210 of the second link member 200b and the protruding area 220 of the first link member 200a in the front-to-back direction increases, causing the second-first cable 321 to be stretched. As a result, tension is applied to the second-first cable 321, and assistive power is generated in a direction opposite to the direction in which two adjacent link members 200 (for example, the first link member 200a and the second link member 200b) move away from each other.

[0066] The second-second cable 322 can be configured to generate tension when the wearer of the device 10 for assisting muscle strength bends backward. Figures 1 to 3 When the wearer of the device for assisting muscle strength 10 performs a stretching exercise while bending backward, the distance between the rear area of ​​the base area 210 of the second link component 200b and the protruding area of ​​the first link component 200a in the front-to-back direction increases, causing the second-second cable 322 to stretch. Consequently, tension is applied to the second-second cable 322, generating an assistive force in a direction opposite to the direction in which the two adjacent link components 200 (e.g., the first link component 200a and the second link component 200b) move away from each other. Furthermore, even when the aforementioned assistive force is not required, the second-second cable 322 can be used to stabilize the relative position of the two adjacent link components 200 of the device for assisting muscle strength 10.

[0067] According to the above structure of the present invention, when the wearer wears the device 10 for assisting muscle strength according to one embodiment of the present invention on the waist, auxiliary power will be generated in the direction opposite to the twisting direction of the waist not only when the wearer bends the waist, but also when the wearer twists the waist.

[0068] According to one embodiment of the present invention, when a wearer wears the device 10 for assisting muscle strength and twists their waist, the support member 100 tightly attached to the wearer's waist also twists, causing relative rotational motion between the multiple link members 200 arranged adjacent to each other and located near the twisted waist region. In this situation, relative rotational motion occurs between the link member located above two adjacent link members 200 (e.g., the protruding region 220 of the first link member 200a) and the link member located below two adjacent link members 200 (e.g., the base region 210 of the second link member 200b). Consequently, the length of either the second-first cable 321 or the second-second cable 322 connecting the two adjacent link members 200 increases, generating tension. Since the tension is applied in the opposite direction to the twisting direction of the wearer's waist, it acts as the auxiliary force needed to restore the wearer's twisted waist to its original state.

[0069] Therefore, the device 10 for assisting muscle strength according to one embodiment of the present invention can generate auxiliary power in various directions in response to various changes in the wearer's posture. In particular, when the wearer wears the device 10 for assisting muscle strength and twists the waist while bending over, the device 10 for assisting muscle strength can generate auxiliary power for stretching the waist and simultaneously generate the auxiliary power required to restore the twisted waist to its original state.

[0070] As described above, the second cable member 320 may be provided on the left and right regions of the first cable member 310, respectively. In this case, the second cable member 320 provided on the right region of the first cable member 310 and the second cable member 320 provided on the left region of the first cable member 310 may be configured symmetrically with respect to the first cable member 310. More specifically, the second-first cable 321 of the second cable member 320 provided on the right region of the first cable member 310 and the second-first cable 321 of the second cable member 320 provided on the left region of the first cable member 310 may be arranged symmetrically with respect to the first cable member 310. The second-second cable 322 of the second cable member 320 provided on the right region of the first cable member 310 and the second-second cable 322 of the second cable member 320 provided on the left region of the first cable member 310 may be arranged symmetrically with respect to the first cable member 310.

[0071] Continue to refer Figures 1 to 3 , among the plurality of link members 200 provided in the apparatus for assisting muscle strength 10 according to one embodiment of the present invention, the protruding areas 220 of two adjacent link members 200 may be provided to directly face each other.

[0072] To achieve the above structure, according to one embodiment of the present invention, a through hole 210-1 may be formed in the base region 210 of the link member 200. Specifically, according to one embodiment of the present invention, the through hole 210-1 may be formed extending in the vertical direction in the base region 210 of the first link member 200a and the base region 210 of the second link member 200b, respectively. The protruding region 220 of the first link member 200a and the protruding region 220 of the second link member 200b may pass through the through hole 210-1 of the second link member 200b and directly face each other.

[0073] More specifically, the lower end of the protruding region 220 of the first link member 200a and the upper end of the protruding region 220 of the second link member 200b may contact each other or be spaced apart from each other depending on the degree of bending of the support member 100. More specifically, when the support member 100 is bent forward to a predetermined or set degree or higher, the lower end of the protruding region 220 of the first link member 200a and the upper end of the protruding region 220 of the second link member 200b may be spaced apart from each other. When the support member 100 is bent forward to a degree lower than the predetermined or set degree, the lower end of the protruding region 220 of the first link member 200a and the upper end of the protruding region 220 of the second link member 200b may contact each other.

[0074] When the lower end of the protruding area 220 of the first link member 200a and the upper end of the protruding area 220 of the second link member 200b contact each other, the first link member 200a can be supported by the second link member 200b, and the wearer of the device for assisting muscle strength 10 can be in a state where the waist is stretched. Therefore, the device for assisting muscle strength 10 according to one embodiment of the present invention can not only provide auxiliary power to assist the strength of the waist muscles when the wearer's waist is bent, but also provide support force to support the wearer's waist when the waist is stretched. Therefore, the wearer's waist can be effectively supported when the wearer is standing while holding an object or when the wearer is moving while holding an object.

[0075] To provide the aforementioned support force, according to one embodiment of the present invention, either the lower end of the protruding region 220 of the first link member 200a or the upper end of the protruding region 220 of the second link member 200b may include a curved protrusion 220a that protrudes while having a curved shape, and the other of the lower end of the protruding region 220 of the first link member 200a and the upper end of the protruding region 220 of the second link member 200b may include a curved recessed portion 220b having a shape corresponding to the curved protrusion 220a. For example, the curved protrusion 220a may be a spherical joint member. When the lower end of the protruding region 220 of the first link member 200a and the upper end of the protruding region 220 of the second link member 200b contact each other, the curved protrusion 220a is accommodated in the curved recessed portion 220b and presses against it, thereby generating the aforementioned support force.

[0076] For example, Figures 1 to 3 As shown, the bent protrusion 220a may be provided at a lower end of the protruding region 220 of the first link member 200a, and the bent recess 220b may be provided at an upper end (eg, upper surface) of the protruding region 220 of the second link member 200b.

[0077] Hereinafter, the detailed shape of the protruding area 220 of the link member 200 will be described. However, in the apparatus for assisting muscle strength according to one embodiment of the present invention, the detailed shape of the protruding area 220 is not necessarily limited to the shape to be described below.

[0078] refer to Figures 1 to 4 The protruding region 220 may include a first extending section 222 extending in a direction intersecting the up-down direction. In this example, a curved recessed portion 220b may be provided on an upper surface of the first extending section 222 of the protruding region 220 of the second link member 200b.

[0079] The protruding region 220 may include a connecting section 224 extending downward from one side of the first extending section 222, and a second extending section 226 connected to the lower end of the connecting section 224 and extending in a direction intersecting the up-down direction. In this example, a curved protrusion 220a may be provided on the lower surface of the second extending section 226 of the protruding region 220 of the first link member 200a.

[0080] For example, Figures 1 to 4 As shown, the first extension section 222 and the second extension section 226 may each have a shape extending in a substantially left-right direction, and the longitudinal direction of the first extension section 222 and the longitudinal direction of the second extension section 226 may be parallel to each other.

[0081] According to an example embodiment of the present invention, the connecting section 224 may include a section extending downwardly at an angle. More specifically, the connecting section 224 may include a first connecting section 224a extending downwardly at an angle from one longitudinal end of the first extending section 222, and a second connecting section 224b extending downwardly at an angle from the other longitudinal end of the first extending section 222. The lower end of the first connecting section 224a and the lower end of the second connecting section 224b may converge. For example, the combination of the first extending section 222, the first connecting section 224a, and the second connecting section 224b may have a substantially triangular shape that is symmetrical in the left-right direction. In this example, the second extending section 226 may connect to the lower ends of the first connecting section 224a and the second connecting section 224b.

[0082] Continue to refer Figures 1 to 4 , the protruding connection portion 226a may be provided on one longitudinal side of the second extension section 226 and have a shape protruding in the up-down direction, and the second cable members 320 may be connected to the protruding connection portions 226a, respectively. In this exemplary case, according to one embodiment of the present invention, one side of the second-first cable 321 and one side of the second-second cable 322 may be connected to the protruding connection portions 226a, respectively. According to one embodiment of the present invention, in addition to the protruding connection portion 226a, the device 10 for assisting muscle strength may further include portions connected to one side of the first cable member 310 or one side of the second cable member 320, which are formed on the base region 210 of the first link member 200a or the second link member 200b and protrude in the up-down direction (see Figures 1 to 4 ). However, for the convenience of description, in this specification, the above-mentioned portion will be considered as a part of the base area 210 and described.

[0083] As described above, the second cable member 320 can be disposed on the left and right sides of the first cable member 310. Therefore, the protruding connection portions 226a connected to one side of the second cable member 320 can also be disposed on the left and right sides of the first cable member 310. For example, the protruding connection portions 226a can be disposed on two opposing longitudinal sides of the second extension section 226. The lower end of the connection section 224 (i.e., the portion where the first and second connection sections meet) can be disposed between the two protruding connection portions 226a disposed on the opposing longitudinal sides of the second extension section 226.

[0084] The plurality of first-first cables 311 provided in the apparatus 10 for assisting muscle strength according to one embodiment of the present invention may be provided as separate components without being connected to each other. The plurality of first-second cables 312 may also be provided as separate components without being connected to each other. That is, according to the present invention, one first-first cable 311 may be configured to connect only two adjacent link components 200 among the plurality of link components 200 provided in the apparatus 10 for assisting muscle strength, and one first-second cable 312 may be configured to connect only two adjacent link components 200 among the plurality of link components 200 provided in the apparatus 10 for assisting muscle strength. These features can be seen from Figures 1 to 3 , in which the plurality of first-first cables 311 are spaced apart from each other in the up-down direction based on the base region 210 , and the plurality of first-second cables 312 are spaced apart from each other in the up-down direction based on the base region 210 .

[0085] It should be noted that the structure of the device for assisting muscle strength 10 described in this specification has been described with reference to an example case in which a wearer wears the device for assisting muscle strength 10 and can stand without bending forward or backward, unless otherwise explicitly stated. It is obvious to a person skilled in the relevant art that Figures 1 to 4 The example embodiments described and illustrated in the accompanying drawings may be flipped upside down to provide equivalent embodiments with equivalent capabilities.
