In an embodiment, the proximal wearing member 91 may be worn on a proximal part of the user H. It should be noted that a position at which the proximal wearing member 91 is worn is not limited thereto. For example, the proximal wearing member 91 may be disposed on the lower body of the user H, the upper arm of the user H, the lower arm of the user H, or the foot of the user H. The proximal wearing member 91 may be produced to have a shape suitable for the body part on which the proximal wearing member 91 is worn.
In an embodiment, the proximal wearing member 91 may include a support for supporting a plurality of wearing stations 94. The wearing stations 94 refers to regions where the actuator 11 is mounted. For example, the wearing stations 94 may be recessed inside the proximal wearing member 91. In this case, the inside of the proximal wearing member 91 is a surface facing the user H's body. The wearing stations 94 may be provided with a fixing member (not shown) for fixing the actuator 11. For example, the actuator 11 may be screwed to the wearing stations 94. For another example, the actuator 11 may be attached to the wearing stations 94. The wearing stations 94 may be provided with a Velcro structure. In an embodiment, the actuator 11 may be a modular actuator 11 attachably or detachably connected, directly or indirectly, to the wearing stations 94. The plurality of wearing stations 94 is illustrated as four on the back, but their number and their position are not limited thereto.
In an embodiment, a first part and a second part to which the distal wearing member 92 is attached may be different from parts to which the proximal wearing member 91 is attached. The first part and the second part may be distal parts. For example, the first part of the user H may be a wrist of the user H. For example, the second part of the user H may be a thigh of the user H. It should be noted that the positions of the first part and the second part are not limited thereto.
In an embodiment, the wearable exercise device 1 may include any one of the first distal wearing member 92 and the second distal wearing member 93. For example, the wearable exercise device 1 may include only the first distal wearing member 92 that is worn on the wrist to assist the upper body exercise of the user H. In this case, the proximal wearing member 91 may have a vest-like shape that is worn on the upper body of the user H and surrounds the chest. For another example, the wearable exercise device 1 may include only the second distal wearing member 93 that is worn on the thigh to assist the lower body exercise of the user H. In this case, the proximal wearing member 91 may have a belt-like shape that is worn on the waist of the user H. Hereinafter, for ease of description, the wearable exercise device 1 including the distal wearing member 93 that is worn on the thigh of the user H and the cable 12 connected, directly or indirectly, to the distal wearing member 93 is mainly described.
In an embodiment, the cable 12 may transmit power generated by the actuator 11 to the distal wearing member 93. For example, the cable 12 may not be elastic. In this case, the cable 12 may transmit most of power output from the actuator 11 to the body of the user H. For another example, the cable 12 may be elastic. In this case, the cable 12 may absorb some of the power output from the actuator 11.
In an embodiment, a plurality of cables 12 may receive power from one actuator 11 and may transmit the received power to one distal wearing member 93. One actuator 11 may control the tension of the plurality of cables 12. For example, when two cables 12 are provided, one may be referred to as a front cable 12a and the other may be referred to as a rear cable 12b. The front cable 12a may extend from the actuator 11, may pass through a cable guide 13a, and then, may be connected, directly or indirectly, to the front of the distal wearing member 93. The rear cable 12b may extend from the actuator 11, may pass through a cable guide 13b, and then, may be connected, directly or indirectly, to the rear of the distal wearing member 93.
In an embodiment, a travel path of the cable 12 may be guided by the cable guide 13. One cable 12 may pass through one cable guide 13. The cable 12 extending from the actuator 11 may enter inside the cable guide 13, and then may pass through the cable guide 13 to be connected, directly or indirectly, to the distal wearing member 93. The cable guide 13 may protect the cable 12 from external shock. In an embodiment, considering appearance, the cable guide 13 may be at least partially covered by the proximal wearing member 91.

In an embodiment, the cable tube 131 may cover the cable 12. The cable 12 may move relative to the cable tube 131 inside the cable tube 131. To reduce the friction between the cable 12 and the cable tube 131, the cable tube 131 may be formed of a material having a relatively flexible and smooth surface. For example, the cable tube 131 may be formed of a thermoplastic polyurethanes (TPU) material. The damage and wear of the cable 12 due to the friction between the cable 12 and the cable tube 131 may be reduced.
In an embodiment, the cable tube 131 may be connected, directly or indirectly, to an actuator (e.g., the actuator 11 of
In an embodiment, the fixed part 1321 may be connected, directly or indirectly, to the actuator. For example, the fixed part 1321 may be directly connected to the actuator through a fixed body 1321a where threads are formed. However, it should be noted that a means of connection between the fixed part 1321 and the actuator is not limited thereto. The fixed part 1321 may include the fixed body 1321a that is connected to the actuator, a base plate 1321b of which the center is penetrated and has a circular shape, and an inner wall 1321c and an outer wall 1321d that extend from the base plate 1321b. The inner wall 1321c may extend in a vertical direction from an inner edge of the base plate 1321b. The outer wall 1321d may extend in a vertical direction from an outer edge of the base plate 1321b. The cable 12 may pass through the penetrated center of the base plate 1321b, and then may reach the rotating part 1322.
In an embodiment, the rotating part 1322 may connect one end of the cable tube 131 to the fixed part 1321. The rotating part 1322 may include a rotating body 1322a that is rotatably connected, directly or indirectly, to the fixed part 1321 and a rotating head 1322b that is connected, directly or indirectly, to the rotating body 1322a. After inserting one end of the rotating body 1322a into the inside of one end of the cable tube 131 and disposing a packing 1325 on the outside of the end of the cable tube 131, the rotating body 1322a and the rotating head 1322b may be connected, directly or indirectly, to fix the cable tube 131 to the rotating part 1322. For example, the rotating head 1322b may be screwed to threads formed on the surface of the rotating body 1322a. In this case, the packing 1325 may be formed of an elastic material, like rubber.
In an embodiment, the rotating part 1322 may be rotatably connected, directly or indirectly, to the fixed part 1321. The other end of the rotating body 1322a may be connected, directly or indirectly, to the fixed part 1321 through the inner bearing 1323 and the outer bearing 1324. The inner bearing 1323 may be supported by the inner wall 1321c, and the outer bearing 1324 may be supported by the outer wall 1321d. The diameter of the outer bearing 1324 may be greater than the diameter of the inner bearing 1323. The rotating part 1322 may be supported by the inner bearing 1323 and the outer bearing 1324 and may rotate relative to the fixed part 1321. The rotation axis of the rotating part 1322 may be parallel to a longitudinal direction of the rotating part 1322. In this structure, the degree of freedom of the cable tube 131 with respect to a proximal wearing member may increase.
In an embodiment, to reduce the friction between the cable 12 and the connector 132, a TPU coating layer C may be disposed on the surface of the rotating body 1322a, the inner wall 1321c, and the fixed body 1321a exposed to a path through which the cable 12 travels.
The cable chain 133, according to an embodiment, may include a plurality of chain links 1331a and 1331b connected to each other. The cable tube 131 may extend inside the chain links 1331a and 1331b. Either one of the chain links 1331a and 1331b may be rotatably connected to the adjacent chain link 1331b or 1331a. In this structure, the cable chain 133 may form the path of the cable tube 131. The chain links 1331a and 1331b may be provided in a plurality of types having different structures to guide a traveling direction of the cable tube 131. In this case, the traveling direction of the cable 12 refers to the traveling direction of the cable 12 toward a distal wearing member inside the cable tube 131.
In an embodiment, the chain link 1331a may guide the path of the cable tube 131 to travel only on the same plane. In this case, the chain link 1331a may also be referred to as an extension link. Based on
In an embodiment, a pair of rollers 1332 may be disposed inside the extension link 1331a. For example, the pair of rollers 1332 may be disposed at a point where two adjacent extension links 1331a are connected. A rotation axis of the pair of rollers 1332 may be parallel to the rotation axis of the extension link 1331a. The cable tube 131 may pass through between the pair of rollers 1332 and may be supported by each of the rollers 1332. In this structure, the friction between the cable tube 131 and the cable chain 133 may be reduced. Meanwhile, it should be noted that a position where the pair of rollers 1332 is disposed within the extension link 1331a is not necessarily limited thereto.
In an embodiment, the chain link 1331b may change a travel path of the cable tube 131, which may extend only on the same plane, to another plane. In this case, the chain link 1331b may also be referred to as the rotation link 1331b. As illustrated in
In an embodiment, one end of the rotation link 1331b has the same structure as that of one end of the extension link 1331a and may be connected to the extension link 1331a. The surfaces of the rotation links 1331b facing each other may be connected to each other through a link bearing 1333. The diameter of the link bearing 1333 may be greater than the diameter of the cable tube 131 such that the cable tube 131 may pass through the link bearing 1333. Based on

In an embodiment, the cover body 1341 may be connected to an end of the cable tube. The cover body 1341 may be formed of, for example, a polyoxymethylene (POM) material. The cover body 1341 may have a tapered structure whose cross-sectional area increases as away from the cable tube along the traveling direction of the cable 12. In this structure, a sufficient range within which the cable 12 getting out of the cable tube may move in a direction intersecting the traveling direction may be secured.
In an embodiment, the ring part 1343 is disposed in the inner side of the cover body 1341 and may reduce the friction between the cable 12 and the cover body 1341. In an embodiment, there may be a plurality of ring parts 1343 arranged side by side. The ring part 1343 may include a ring base 1343a, a ring protrusion 1343b, and a plurality of friction reduction members 1343c.
In an embodiment, the ring base 1343a may have a ring shape. The ring protrusion 1343b may extend in a radial direction from the ring base 1343a. The ring protrusion 1343b may be accommodated by a cover groove 1342 formed in the inner side of the cover body 1341. For example, there may be a plurality of ring protrusions 1343b spaced apart from one another along the circumference of the ring base 1343a. With the ring protrusion 1343b of the ring part 1343 accommodated by the cover groove 1342, the ring part 1343 may be fixed to the cover body 1341.
In an embodiment, the plurality of friction reduction members 1343c may be penetrated by the ring base 1343a and may be connected, directly or indirectly, to the ring base 1343a. The friction reduction member 1343c may be spaced apart from the cover body 1341. The ring base 1343a may penetrate the friction reduction member 1343c in a curved line rather than a straight line. Based on the cross-section, a diameter d1 of a hole of the friction reduction member 1343c penetrated by the ring base 1343a may be greater than a thickness d2 of the ring base 1343a such that the friction reduction member 1343c may rotate with respect to the ring base 1343a. When the cable 12 contacts the friction reduction member 1343c, the friction reduction member 1343c rotates with respect to the ring base 1343a while being swept by the cable 12, and the friction between the cover body 1341 and the cable 12 may be reduced.
In an embodiment, based on the cross-section viewed from the traveling direction of the cable 12, the size of the friction reduction member 1343c may be less than the diameter of the cable 12. In this structure, the cable 12 may pass through the ring part 1343 without being caught between two adjacent friction reduction members 1343c. Meanwhile, it should be noted that the shape of the friction reduction member 1343c may vary. For example, the friction reduction member 1343c may have a roller shape rather than a ball shape.

In an embodiment, the housing 111 may surround a motor (not shown), a reducer (not shown), the level guide shaft 112, the level guide body 114, the spool 116, and the screw 118. One end of the cable 12 may be fixed to the spool 116. The spool 116 rotates in one direction or the other direction opposite to the direction such that at least a portion of the cable 12 may be wound around or unwound from the spool 116. The position of the cable 12 wound around the spool 116 may be changed to a direction parallel to a rotation axis direction of the spool 116 by the level guide shaft 112 and the level guide body 114.
In an embodiment, the level guide shaft 112 may be provided in parallel to the spool 116. The level guide shaft 112 is connected to the spool 116 through a first pulley belt 117 and may rotate with the spool 116 by receiving power from the motor. The rotation axis of the level guide shaft 112 may be parallel to a longitudinal direction of the level guide shaft 112 and may be parallel to a rotation axis of the spool 116.
In an embodiment, the level guide body 114 may be connected, directly or indirectly, to the level guide shaft 112. The center of the level guide body 114 may be penetrated by the level guide shaft 112. The level guide body 114 may support each of the upper and lower sides of the cable 12. In this structure, when the level guide body 114 moves upward and downward on the level guide shaft 112, the portion of the cable 12 supported by the level guide body 114 may move upward and downward. In this case, the upward and downward directions are parallel to the longitudinal direction of the level guide shaft 112.
In an embodiment, a portion of the level guide body 114 may be movably connected, directly or indirectly, to a support bar 115 fixed inside the housing 111. For example, the support bar 115 may penetrate the level guide body 114. The level guide body 114 is tied to the support bar 115 such that the level guide shaft 112 may rotate relative to the level guide body 114. When the level guide shaft 112 rotates, the level guide body 114 may move upward and downward along the level guide groove 113 recessed from a surface of the level guide shaft 112.
In an embodiment, the level guide body 114 may be connected to the level guide shaft 112 through at least a guide protrusion (not shown). The guide protrusion may be provided inside the level guide body 114 facing the level guide shaft 112. The guide protrusion may be accommodated by the level guide groove 113 formed on the surface of the level guide shaft 112. The guide protrusion may rotate in a direction protruding from the level guide body 114 as a rotation axis.
In an embodiment, the level guide groove 113 may have a diamond pattern shape. When the level guide shaft 112 rotates, a diagonal direction (e.g., upward to the right) of the level guide groove 113 that guides the level guide body 114 to the upper side may be different from a diagonal direction (e.g., downward to the right) of the level guide groove 113 that guides the level guide body 114 to the lower side. For example, the guide protrusion is accommodated by the level guide groove 113 formed upwardly to the right and the level guide shaft 112 rotates in one direction such that the level guide body 114 may reach an upper end of the level guide shaft 112. Then, the guide protrusion may rotate with respect to the level guide body 114 such that the guide protrusion may be accommodated by the level guide groove 113 formed downward to the right along an upper boundary of the level guide groove 113 leading from upward to the right to downward to the right. The guide protrusion is accommodated by the level guide groove 113 formed downward to the right and the level guide shaft 112 rotates in one direction such that the level guide body 114 may reach a lower end of the level guide shaft 112. Then, the guide protrusion may be accommodated by the level guide groove 113 formed upwardly to the right along a lower boundary of the level guide groove 113 leading from downward to the right to upward to the right.
In this mechanism, when the level guide shaft 112 continuously rotates in one direction or its opposite direction, the level guide body 114 may reciprocate in a direction parallel to a rotation axis direction of the level guide shaft 112. The level guide body 114 moves along the level guide groove 113 such that the height of the cable 12 wound around the spool 116 may be changed, and the cable 12 may be uniformly wound around the spool 116. The tangle and wear of the cable 12 may be reduced.
In an embodiment, at least a portion of the cable 12 extending from the level guide body 114 to the outside of the housing 111 may contact the screw 118. The screw 118 may maintain the cable 12 getting out of the housing 111 at a uniform height. The screw 118 may include a screw shaft 1181, a clutch 1182, a screw body 1183, an upper thread 1184, a lower thread 1185, and a core groove 1186.
In an embodiment, the screw shaft 1181 may be parallel to the level guide shaft 112. The screw shaft 1181 may rotate by receiving power from the level guide shaft 112. For example, the screw shaft 1181 and the level guide shaft 112 may be connected to each other through a second pulley belt 119. A rotation axis of the screw axis/shaft 1181 may be parallel to the rotation axis of the level guide axis/shaft 112.
In an embodiment, the clutch 1182 surrounds the screw shaft 1181 and may transmit power in only one direction around the screw shaft 1181. The clutch 1182 may be a one-way clutch. In an embodiment, the clutch 1182 may include an inner race 1182a, an outer race 1182b, and a rolling element 1182c. The inner race 1182a may have a structure having a plurality of protrusions along a circumference around a rotation axis whose protruding height increases as it gets further away from the rotation axis. When the inner race 1182a rotates in any one direction (e.g., a clockwise direction of
In an embodiment, the screw body 1183 may surround the clutch 1182. The screw body 1183 may rotate by receiving power in only one direction from the outer race 1182b of the clutch 1182.
In an embodiment, the upper thread 1184, the lower thread 1185, and the core groove 1186 may be formed on a surface of the screw body 1183. The core groove 1186 is recessed from the surface of the screw body 1183 and may be formed between the upper thread 1184 and the lower thread 1185. For example, based on a longitudinal direction of the screw body 1183, a height at which the lower thread 1185 is formed may be the same as a height at which the upper thread 1184 is formed. The cable 12 seated in the core groove 1186 may move in a direction intersecting a rotation axis of the screw body 1183. For example, the cable 12 seated in the core groove 1186 moves in a direction perpendicular to the rotation axis of the screw body 1183, and the whole cable 12 may travel in a direction parallel to the bottom surface of the housing 111.
In an embodiment, the upper thread 1184 and the lower thread 1185 may guide the cable 12 to be seated in the core groove 1186. The directions in which the upper thread 1184 and the lower thread 1185 are formed may be opposite to each other. For example, as illustrated in

In an embodiment, the plurality of tube magnets 135a, 135b, 135c, 135d, and 135e may be provided. In the cable tube 131, a gap between adjacent tube magnets among the plurality of tube magnets 135a, 135b, 135c, 135d, and 135e may decrease as it gets closer to the distal wearing member based on a traveling direction of the cable 12. For example,
In an embodiment, when the cable 12 gets closer to the cable tube 131, the first tube magnet 135a applies magnetic force to the cable magnet 14, and the cable magnet 14 and the cable 12 may move in the traveling direction inside the cable tube 131. The cable 12 moves in the traveling direction, and the cable magnet 14 may reach between the first tube magnet 135a and the second tube magnet 135b. In this case, the magnetic force applied to the cable magnet 14 by the second tube magnet 135b to the fifth tube magnet 135e may be greater than the magnetic force applied to the cable magnet 14 by the first tube magnet 135a. The cable magnet 14 moves toward the second tube magnet 135b by magnetic force, and the cable 12 may move in the traveling direction. The cable 12 moves in the traveling direction, and the cable magnet 14 may reach between the second tube magnet 135b and the third tube magnet 135c. In this case, the magnetic force applied to the cable magnet 14 by the third tube magnet 135c to the fifth tube magnet 135e may be greater than the magnetic force applied to the cable magnet 14 by the first tube magnet 135a and the second tube magnet 135b. The cable magnet 14 moves toward the third tube magnet 135c by magnetic force, and the cable 12 may move in the traveling direction. Through this process, the cable magnet 14 that has passed through the first tube magnet 135a may pass through the fifth tube magnet 135e only by magnetic force and may get out of the cable tube 131. The process of the cable 12 passing through the cable tube 131 may be simplified.
It has been described that the number of tube magnets 135a, 135b, 135c, 135d, and 135e are five, but it should be noted that the number of tube magnets disposed in the cable tube 131 may be less than or greater than five.
Referring to
In an embodiment, the holder body 151 may be connected to the distal wearing member. For example, a lower part of the holder body 151 may extend further downward to form a ring (not shown), and the distal wearing member may be connected to the ring of the holder body 151. Based on
In an embodiment, the holder head 152 extends from the holder body 151 and may cover at least a portion of the cable magnet 14. The holder head 152 may have a cup shape with seating space therein.
In an embodiment, the holder groove 153 may be recessed from the holder head 152. The holder groove 153 is recessed from the outside toward the center of the holder head 152 and may communicate with the seating space of the holder head 152. After the cable 12 passes through the holder groove 153 and is aligned with the center of the holder head 152, when the cable 12 is pulled in a direction away from the distal wearing member, the cable magnet 14 may get closer to the holder head 152. When the cable magnet 14 reaches a specific position, the magnetic force of the holder magnet 154 disposed inside the holder head 152 may act on the cable magnet 14. The cable magnet 14 is seated in the seating space by magnetic force and may remain supported by the holder head 152. Meanwhile, it should be noted that the holder magnet 154 may be disposed on a side of the holder head 152 facing the cable magnet 14.
In an embodiment, a cap 16 may be additionally connected to the cable 12. The cap 16 may be formed of, for example, an elastic material, like rubber. The cap 16 may be positioned between the holder head 152 and the cable magnet 14. The cap 16 may directly contact the holder head 152 instead of the cable magnet 14. When great force is applied to the cable 12 due to a sudden motion of a user, the degree to which the cable magnet 14 is pressed by the holder head 152 decreases, and the damage or breakage of the cable magnet 14 may decrease.
