Description

shoulder training device

[0001] The present invention relates to a shoulder training device, and more particularly, to a shoulder training device that enables a trainee to train the movement of the shoulder joint in a sitting position.

[0002] The shoulder joint has movement in all three planes. Anatomically, it is a ball-and-socket joint. However, it is less anchored by bones and more stabilized by muscles and ligaments, making it the most mobile joint in the human body. Movements of the shoulder joint include flexion, extension, abduction, adduction, external rotation, and internal rotation of the upper arm.

[0003] Typically, shoulder training devices are designed to aid in the rehabilitation of individuals with shoulder paralysis or those with problems with shoulder joint strength or endurance. Because individuals with shoulder immobility often have difficulty moving their arms independently, they perform shoulder training by wearing a shoulder training device and moving their arms according to the device's induced movement patterns. These shoulder training devices have a unique movement trajectory based on their structure.

[0004] However, conventional shoulder training devices were separate for left and right shoulders. To provide both left and right shoulder training, separate shoulder training devices were required. Furthermore, if the shoulder training device did not correspond to the shoulder requiring training, shoulder training could not be performed. Furthermore, if one were to switch from training one shoulder to training the other, the shoulder training device would also need to be changed.

[0005] To solve these problems, there have been various attempts, such as adding additional joints to the shoulder training device and allowing each joint to move each shoulder joint. However, the addition of joints may cause new problems, such as making the structure of the shoulder training device more complex or making it difficult to wear.

[0006] (Patent Document 1) Korean Patent No. 10-1331071

[0007] The present invention provides a shoulder training device that allows a trainer to selectively train the left shoulder and the right shoulder.

[0008] A shoulder training device according to one embodiment of the present invention includes a seat on which a trainee can sit; a support member for supporting the seat member; a backrest provided on one side or the other of the seat member in a first direction; and a shoulder movement guide member provided on one side of the seat member in a second direction intersecting the first direction to guide movement of a shoulder of one side selected from the left and right sides of the trainee; wherein the backrest can be positionally changed with respect to the shoulder movement guide member to one side or the other of the first direction.

[0009] The seat part further includes a plurality of backrest fixing parts provided on one side and the other side of the first direction, respectively, and the backrest is selectively coupled to and separated from the plurality of backrest fixing parts so that the relative position with respect to the shoulder movement guide part can be changed to one side or the other side of the first direction of the seat part.

[0010] It may further include a guide moving part that moves the shoulder movement guide part in the first direction.

[0011] The above backrest changes its relative position with respect to the shoulder movement guide part depending on the selection of either the left or right side, and the guide moving part can move the shoulder movement guide part in a direction closer to the backrest.

[0012] The above guide moving part may include a plurality of rail parts that extend in the first direction and are provided in parallel with each other; and a moving body that is connected to the shoulder movement guide part and can move along the plurality of rail parts.

[0013] It may further include a guide height adjustment unit for adjusting the vertical position of the shoulder movement guide unit.

[0014] The above guide height adjustment unit may include a weight compensation unit that compensates for the weight of the shoulder movement guide unit.

[0015] The shoulder movement guide unit may include an arm fixing unit that at least partially fixes one arm of the trainer; an up-and-down movement guide unit that is connected to the arm fixing unit and rotates the arm fixing unit in an up-and-down direction for up-and-down rotational movement of the one shoulder; and a left-and-right movement guide unit that is connected to the up-and-down movement guide unit and rotates the arm fixing unit in a left-and-right direction together with the up-and-down movement guide unit for left-and-right rotational movement of the one shoulder.

[0016] The above-mentioned up-and-down movement guide part may include an up-and-down rotation stopper that limits the up-and-down rotation angle of the arm fixing part, and the above-mentioned left-and-right movement guide part may include an up-and-down rotation stopper that limits the up-and-down rotation angle of the arm fixing part.

[0017] The above-mentioned vertical rotation stopper and the left-right rotation stopper can change the rotation limit angle depending on the selection of either the left or right side.

[0018] The method may further include a control unit that controls the rotation limit angles of the upper and lower rotation stoppers and the left and right rotation stoppers according to the selection of one of the above sides, thereby providing a movement pattern corresponding to the shoulder of each side.

[0019] The above arm fixing member may include a fixing member that is attachable to and detachable from one of the arms; a first rotating member that is connected to the fixing member and rotates the fixing member left and right; and a second rotating member that is connected to the first rotating member and rotates the fixing member up and down together with the first rotating member.

[0020] The above-mentioned arm fixing member may further include a moving member that is connected to the fixing member and moves the fixing member in a direction intersecting the left-right direction.

[0021] It may further include a rotating part that rotates the backrest around the central axis of the support part.

[0022] A shoulder training device according to an embodiment of the present invention can change the position of the backrest relative to the shoulder exercise guide part to one side or the other in the first direction, thereby selecting the left shoulder and the right shoulder to perform shoulder training according to the selection, and switching (or changing) the shoulder to be trained between the left shoulder and the right shoulder.

[0023] At this time, by moving the shoulder exercise guide part in the first direction so as to get closer to the backrest through the guide moving part, training can be selectively provided without covering the left shoulder and the right shoulder (or without distinguishing between the left shoulder and the right shoulder) with one shoulder exercise guide part.

[0024] In addition, by precisely adjusting the position of the shoulder exercise guide part through the guide height adjustment part and the guide movement part in response to the body structure (e.g., body size, etc.) and posture of the trainee to a position where no burden (or discomfort) is transmitted to the trainee's shoulder (e.g., a position where the trainee's shoulder rotation center and the rotational center of the shoulder exercise guide part are the same), it is possible to provide a natural exercise pattern (or movement) suitable for the trainee without burdening the trainee's shoulder, and to enable optimal shoulder training suitable for the trainee.

[0025] In addition to the first and second rotation members that rotate the fixed member left-right and up-down, the arm fixing unit further includes a moving member that can move the fixed member in a direction crossing the left-right direction (for example, forward-backward direction), thereby making it possible to align the trainer's shoulder rotation center (or shoulder joint) with the rotation center point (or rotation reference point) of the shoulder movement guide unit as much as possible. In addition, even if the trainer's shoulder rotation center and the rotation center point of the shoulder movement guide unit do not align, it is possible to minimize the burden on the trainer's shoulder and / or other parts (or portions) of the body.

[0026] Accordingly, it is possible to prevent the occurrence of unexpected injuries during (rehabilitation) training (or rehabilitation treatment) of the trainer's shoulder joint and / or arm (or upper limb) muscles, and at the same time, significantly improve the training (or rehabilitation) effect of the trainer through shoulder training.

[0027] Furthermore, a single shoulder exercise guide unit can provide training to both left and right shoulders, regardless of preference. Furthermore, the arm fixation structure, which includes multiple joints, can be eliminated, thereby reducing the structural complexity of the shoulder training device. Furthermore, this improved structural complexity can improve manufacturing productivity and reduce manufacturing costs.

These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. In the description, identical reference numerals are assigned to identical components, and the drawings may be partially exaggerated in size to accurately describe the embodiments of the present invention, and identical numerals in the drawings indicate identical elements.

[0035]

[0036] FIG. 1 is a drawing showing a shoulder training device according to one embodiment of the present invention.

[0037] Referring to FIG. 1, a shoulder training device (100) according to an embodiment of the present invention may include a seat (110) on which a trainee (10) can sit; a support (120) that supports the seat (110); a backrest (130) provided on one side or the other of the seat (110) in a first direction; and a shoulder movement guide (140) provided on one side of the seat (110) in a second direction intersecting the first direction to guide movement of a shoulder of one side selected from the left and right sides of the trainee (10).

[0038] The seat (110) can be used to allow the trainee (10) to sit and perform shoulder joint training in a seated position. For example, the seat (110) can include a seat that the buttocks of the trainee (10) touch when seated.

[0039] The support member (120) can be fixed (or supported) on a floor surface (e.g., the ground) to support the seat member (110). For example, the support member (120) can be installed vertically on the floor surface, and the seat member (110) can be coupled (or mounted) to the upper portion. Through this, the buttocks of the trainee (10) can be supported to maintain a certain height, thereby enabling the trainee (10) to sit. Meanwhile, the support member (120) can also be configured to be movable by caster wheels, etc.

[0040] A backrest (130) can be provided on one side or the other side of the first direction of the seat portion (110), and a trainee (10) seated on the seat portion (110) can lean his / her back against it, and can be selectively provided on one side or the other side of the first direction.

[0041] The shoulder movement guide unit (140) may be provided on one side of the second direction intersecting the first direction of the seat unit (110), and may guide the movement of either the left or right shoulder of the trainee (10). For example, if the second direction side of the seat unit (110) on which the shoulder movement guide unit (140) is provided is the left side of the trainee (10) leaning back against the backrest (130), the left arm of the trainee (10) may be fixed to guide the movement of the left shoulder. Conversely, if the second direction side of the seat unit (110) is the right side of the trainee (10) leaning back against the backrest (130), the right arm of the trainee (10) may be fixed to guide the movement of the right shoulder.

[0042] Here, the backrest (130) can be positioned relative to the shoulder exercise guide (140) to one or the other side of the first direction, thereby switching (or changing) the shoulder to be trained between the left shoulder and the right shoulder, and selecting one shoulder between the left shoulder and the right shoulder to train the shoulder according to the selection. For example, the backrest (130) can be provided on one side of the seat (110) in the first direction to train the left shoulder, and the backrest (130) can be positioned on the other side of the seat (110) in the first direction to train the right shoulder. Subsequently, the backrest (130) can be positioned (again) on one side of the seat (110) in the first direction to train the left shoulder.

[0043] FIG. 2 is a conceptual diagram for explaining a change in the position of a backrest according to one embodiment of the present invention. FIG. 2 (a) shows a right shoulder training mode, and FIG. 2 (b) shows a left shoulder training mode.

[0044] Referring to FIG. 2, the shoulder training device (100) according to the present invention may further include a plurality of backrest fixing parts (150) provided on one side and the other side of the first direction of the seat part (110).

[0045] A plurality of backrest fixing parts (150) may be provided on one side and the other side of the seat part (110) in the first direction, respectively, and the backrest (130) may be coupled and separated. For example, a plurality of backrest fixing parts (150) may be installed (or attached) to the seat part (110) and / or the support part (120). Accordingly, the backrest (130) may be coupled to the backrest fixing part (150) provided on one side of the seat part (110) in the first direction to train one shoulder of either the left or right side, and the backrest (130) may be coupled to the backrest fixing part (150) provided on the other side of the seat part (110) in the first direction to train the other (or remaining) shoulder of either the left or right side.

[0046] At this time, the backrest (130) can be selectively coupled to and separated from a plurality of backrest fixing parts (150) so that the relative position with respect to the shoulder movement guide part (140) toward one side or the other side of the seat part (110) in the first direction can be changed. That is, the backrest (130) can be selectively coupled to and separated from the backrest fixing part (150) on one side of the first direction and the backrest fixing part (150) on the other side of the first direction. Accordingly, the backrest (130) can be moved toward one side and the other side of the seat part (110) in the first direction, and the relative position of the backrest (130) with respect to the shoulder movement guide part (140) toward one side or the other side of the seat part (110) in the first direction can be changed.

[0047] Here, the plurality of backrest fixing parts (150) may include a backrest connecting part (151) into which at least a portion of the backrest (130) is fitted, and a fixing knob (152) that fixes the backrest (130) fitted to the backrest connecting part (151). The backrest connecting part (151) may be fitted with at least a portion of the backrest (130), and the fixing knob (152) may fix the backrest (130) fitted to the backrest connecting part (151), thereby allowing the backrest (130) to be coupled (or fixed) to the backrest fixing part (150). In addition, by loosening the fixing knob (152) and removing the backrest (130) from the backrest connecting part (151), the backrest (130) may be separated from the backrest fixing part (150). Through this, the backrest (130) can be easily repositioned relative to the shoulder exercise guide part (140) to one or the other side of the first direction, and shoulder training can be provided for both the left shoulder and the right shoulder with just one shoulder exercise guide part (140).

[0048] FIG. 3 is a conceptual diagram for explaining a guide moving part according to one embodiment of the present invention. FIG. 3 (a) is a drawing in which the shoulder movement guide part is located far from the backrest, and FIG. 3 (b) is a drawing in which the shoulder movement guide part is located close to the backrest.

[0049] Referring to FIG. 3, the shoulder training device (100) according to the present invention may further include a guide moving part (160) that moves the shoulder exercise guide part (140) in the first direction.

[0050] The guide moving unit (160) can move the shoulder movement guide unit (140) in the first direction, and can move the shoulder movement guide unit (140) along one side (surface) of the seat unit (110) in the second direction. Through this, the shoulder movement guide unit (140) can be brought closer to the shoulder joint (or shoulder rotation center) of the trainee (10).

[0051] Here, the guide moving part (160) may include a plurality of rail parts (161) that extend in the first direction and are provided parallel to each other; and a moving body (162) that is connected to the shoulder movement guide part (140) and can move along the plurality of rail parts (161). The plurality of rail parts (161) may extend in the first direction and be provided parallel to each other (or in parallel), and may provide a path along which the moving body (162) can move in the first direction. Since the rail parts (161) are configured in plurality, the moving body (162) that pulls the shoulder movement guide part (140) (or is connected to the shoulder movement guide part) can be prevented from being tilted (or twisted) by the load (or weight) of the shoulder movement guide part (140) while moving. For example, the plurality of rail parts (161) may be arranged vertically and provided parallel to each other in the first direction. Meanwhile, a plurality of rail parts (161) can be attached (or installed) to the seat part (110) and / or the support part (120) and supported (or fixed).

[0052] The moving body (162) can move in the extension direction of the rail portion (161) along the plurality of rail portions (161) (i.e., the first direction) and can move the shoulder movement guide portion (140) in the first direction by being connected to the shoulder movement guide portion (140) and pulling the shoulder movement guide portion (140).

[0053] The shoulder movement guide part (140) can be well supported (or pulled) by the plurality of rail parts (161) without the moving body (162) tilting, and accordingly, the shoulder movement guide part (140) can be moved in the first direction more precisely so that the shoulder joint of the trainee (10) and the rotational center point (or rotation reference point) of the shoulder movement guide part (140) are as close as possible to each other.

[0054] At this time, the backrest (130) can change its relative position with respect to the shoulder movement guide part (140) depending on which side is selected between the left and right, and can be provided on one side or the other side in the first direction depending on whether the selected shoulder is the left shoulder or the right shoulder, so that its relative position with respect to the shoulder movement guide part (140) can be changed. In addition, the guide moving part (160) can move the shoulder movement guide part (140) in a direction closer to the backrest (130) depending on whether the backrest (130) is provided on one side in the first direction (or) on the other side in the first direction. That is, the shoulder movement guide part (140) can be moved in a direction closer to the backrest (130) through the guide moving part (160) depending on the relative position of the backrest (130) with respect to the shoulder movement guide part (140). Accordingly, the shoulder exercise guide part (140) can be brought closer to the shoulder joint of the trainee (10), and while performing shoulder training, no burden (or discomfort) can be transmitted to the shoulder of the trainee (10) (as much as possible).

[0055] For example, when the backrest (130) is provided on one side of the seat (110) in the first direction to train the left shoulder (or right shoulder) of the trainee (10), the shoulder movement guide part (140) can be moved to one side of the first direction closer to the backrest (130) to become closer to the left (or right) shoulder joint of the trainee (10). Conversely, when the backrest (130) is provided on the other side of the seat (110) in the first direction to train the right shoulder (or left shoulder) of the trainee (10), the shoulder movement guide part (140) can be moved to the other side of the first direction closer to the backrest (130) to become closer to the right (or left) shoulder joint of the trainee (10).

[0056] Accordingly, the shoulder training device (100) according to the present invention can selectively provide training without covering the left shoulder and the right shoulder (or without distinguishing between the left shoulder and the right shoulder) with one shoulder exercise guide unit (140) by moving the shoulder exercise guide unit (140) to one side or the other in the first direction so as to come closer to the backrest (130) through the guide movement unit (160).

[0057] FIG. 4 is a drawing showing a guide height adjustment unit according to one embodiment of the present invention.

[0058] Referring to FIG. 4, the shoulder training device (100) according to the present invention may further include a guide height adjustment unit (170) that adjusts the vertical position of the shoulder exercise guide unit (140).

[0059] The guide height adjustment unit (170) can adjust the vertical position (or height) of the shoulder exercise guide unit (140), and can match the vertical position of the shoulder exercise guide unit (140) with the height (or vertical position) of the shoulder joint of the trainee (10). The height of the shoulder joint may be different depending on the body structure (e.g., body size, etc.) and / or posture of the trainee (10), and the vertical position of the shoulder exercise guide unit (140) can be adjusted accordingly, and through this, the vertical position of the shoulder exercise guide unit (140) can be matched (as much as possible) with the height of the shoulder joint of the trainee (10).

[0060] For example, it is necessary to change the position of the shoulder movement guide unit (140) corresponding to the shoulder joint (part) depending on the position and direction of the shoulder and / or arm (or upper limb) of the trainer (10), and for this purpose, the upper and lower position of the shoulder movement guide unit (140) can be adjusted through the guide height adjustment unit (170). At this time, the guide moving unit (160) can also move the shoulder movement guide unit (140) in the first direction to adjust the position of the shoulder movement guide unit (140) in the first direction. Here, the guide height adjustment unit (170) can be connected (or coupled) to the moving body (162) of the guide moving unit (160) and can move together with the moving body (162), and the shoulder movement guide unit (140) can be supported (or coupled). Through this, the shoulder movement guide part (140) can be moved in the first direction by the guide moving part (160), and the upper and lower positions of the shoulder movement guide part (140) can be adjusted by the guide height adjusting part (170).

[0061] And the guide height adjustment unit (170) may include a weight compensation unit (175) that compensates for the weight of the shoulder movement guide unit (140). The weight compensation unit (175) may compensate for the weight of the shoulder movement guide unit (140) and may be provided at the lower end of the guide height adjustment unit (170). By compensating for the weight of the shoulder movement guide unit (140) through the weight compensation unit (175), the upper and lower positions of the shoulder movement guide unit (140) may be adjusted without applying force when adjusting the upper and lower positions of the shoulder movement guide unit (140).

[0062] For example, the weight compensation unit (175) may include a spring having elasticity to provide a repulsive force (or compensating force) against the weight (or load) of the shoulder movement guide unit (140); and a spring fixing member that fixes the spring. The spring may have elasticity, provide elasticity in the up-and-down direction (or in the direction of gravity), and support the weight of the shoulder movement guide unit (140) by the elasticity. The spring may provide elasticity (or compensating force) as a repulsive force against the pressure (or gravity) applied by the load of the shoulder movement guide unit (140), thereby compensating for the weight of the shoulder movement guide unit (140).

[0063] The spring fixing member can fix the spring, and can provide the spring's elastic force only in a direction opposite to gravity (i.e., the up-and-down direction) by preventing the spring from being tilted or bent, and can effectively compensate for the weight of the shoulder movement guide part (140). Here, the spring fixing member can include a fixing portion on which one end (or the lower end) of the spring is supported (or settled); and an extension portion that extends vertically (or in the up-and-down direction) from the fixing portion. The fixing portion can provide a bottom surface (or a fixing surface) on which the spring is settled (or supported), and the extension portion can be configured as a protruding column that extends from the center of the fixing portion and is inserted into the center of the spring, or can be configured as a (receiving) wall that extends (or protrudes) from the edge of the fixing portion and surrounds the periphery of the spring.

[0064] At this time, the spring can reduce overshoot of shoulder movement or suppress vibration generated by the shoulder movement guide unit (140).

[0065] The weight compensation unit (175) can compensate for the gravity of the weight of the shoulder movement guide unit (140) in the above-mentioned up-and-down direction while allowing free movement (position) of the shoulder movement guide unit (140) in the above-mentioned up-and-down direction.

[0066] Meanwhile, the spring constant (k) of the weight compensation unit (175) can be determined by the following equation depending on the vertical movement range (stroke) of the shoulder joint and the load to be compensated.

[0067] k = E / s (where k is the total spring constant and E is the gravity compensation tolerance (W max -W min ) and W max is the total compensation load (the weight of the trainee's arm + the weight of the shoulder exercise guide part above), and W min is the minimum compensation load, and s is the vertical range of movement of the shoulder joint.)

[0068] The above gravity compensation tolerance (E) is the allowable difference between the maximum and minimum compensation force within the vertical movement range of the shoulder joint. Due to the characteristics of the weight compensation unit (175) using the spring, it is impossible to compensate for a constant force throughout the entire range of motion. However, by adjusting the spring constant (k), the tolerance can be determined by taking into account the severity (or symptom level) of the trainee (10) and the environment in which the shoulder movement guide unit (140) is installed.

[0069] FIG. 5 is a conceptual diagram for explaining the vertical position adjustment of a shoulder movement guide part according to one embodiment of the present invention. FIG. 5 (a) shows the minimum height, FIG. 5 (b) shows the middle height, and FIG. 5 (c) shows the maximum height.

[0070] Referring to FIG. 5, the vertical position of the shoulder exercise guide part (140) can be adjusted from minimum height ↔ middle height ↔ maximum height, and the vertical position of the shoulder exercise guide part (140) can be adjusted according to the shoulder position of the trainee (10) and / or various body types of the trainee (10).

[0071] Accordingly, the shoulder training device (100) according to the present invention precisely adjusts the position of the shoulder movement guide unit (140) to a position where no burden is transmitted to the shoulder of the trainee (10) (for example, a position where the rotation center of the shoulder of the trainee and the rotation center (point) of the shoulder movement guide unit coincide) through the guide height adjustment unit (170) and the guide movement unit (160) in response to the body structure and posture of the trainee (10), thereby providing a natural movement pattern (or movement) suitable for the trainee (10) without placing a burden on the shoulder of the trainee (10), and enabling optimal shoulder training suitable for the trainee (10).

[0072] Meanwhile, even for the same trainee (10), depending on the body structure and / or posture of the trainee (10), the upper and lower positions and / or the first direction positions of the left shoulder and the right shoulder may be different, and the position of the shoulder movement guide unit (140) may be adjusted (or controlled) to suit the joint position of each shoulder.

[0073] Fig. 6 is a drawing showing a shoulder movement guide part according to one embodiment of the present invention.

[0074] Referring to FIG. 6, the shoulder movement guide unit (140) may include an arm fixing unit (141) that fixes at least a portion of one arm of the trainee (10); an up-and-down movement guide unit (142) that is connected to the arm fixing unit (141) and rotates the arm fixing unit (141) up and down for up-and-down rotational movement of the one shoulder; and a left-and-right movement guide unit (143) that is connected to the up-and-down movement guide unit (142) and rotates the arm fixing unit (141) left-and-right together with the up-and-down movement guide unit (142) for left-and-right rotational movement of the one shoulder. The arm fixing unit (141) may fix at least a portion of the one arm of the trainee (10) and may be worn on the arm of the trainee (10) that is to be trained. For example, the arm fixing unit (141) may be configured to support or be fitted onto a portion of the arm of the trainee (10).

[0075] The up-and-down movement guide unit (142) can be connected to the arm fixing unit (141), and can rotate the arm fixing unit (141) up and down for the up-and-down rotational movement of the shoulder on either side. By rotating the arm fixing unit (141) in the up-and-down direction through the up-and-down movement guide unit (142), the arm (on the side) wearing the arm fixing unit (141) can be rotated (moved) in the up-and-down direction, and accordingly, the shoulder on the side wearing the arm fixing unit (141) can perform the up-and-down rotational movement.

[0076] For example, the up-and-down movement guide unit (142) may include a first guide member (142a) that is connected to the arm fixing unit (141) and can rotate in the up-and-down direction so that the arm of the trainee (10) fixed to the arm fixing unit (141) can perform a circular movement in the up-and-down direction. The first guide member (142a) may be formed in an arc shape, and may be connected to the arm fixing unit (141) and rotatably coupled to the left-right movement guide unit (143). Here, the first guide member (142a) may have an arc shape and may be provided as a C-shaped frame. At this time, the first guide member (142a) may be formed in an arc shape of a circle having a first radius, and may be formed as a frame in an arc shape with a center angle of about 80° to 110° or 85° to 105°. For example, the first guide member (142a) may be formed as a frame having an arc shape (i.e., an arc shape of 1 / 4 of a circle) with a center angle of 90° from the first point where the arm fixing member (141) is coupled to the second point where the left-right movement guide member (143) is connected (or coupled). Meanwhile, the center angle from the first point to the second point of the first guide member (142a) may be varied within a range of 80° to 110°.

[0077] The left-right movement guide unit (143) can be connected to the up-down movement guide unit (142), and can rotate the arm fixing unit (141) in the left-right direction together with the up-down movement guide unit (142) for the left-right rotational movement of one shoulder. Through the left-right movement guide unit (143), the arm fixing unit (141) can be rotated in the left-right direction, thereby rotating (moving) the arm (on the side) wearing the arm fixing unit (141) in the left-right direction, and accordingly, the shoulder on the side wearing the arm fixing unit (141) can perform the left-right rotational movement.

[0078] For example, the left-right movement guide unit (143) may be connected to the up-and-down movement guide unit (142) and may include a second guide member (143a) that can rotate left-and-right so that the arm of the trainee (10) fixed to the arm fixing unit (141) can perform circular movement in the left-and-right direction. The second guide member (143a) may be formed in an arc shape, and may be connected to the up-and-down movement guide unit (142) so as to be rotatably coupled to the support member (120), and may be coupled to the support member (120) via the guide moving member (160) and / or the guide height adjusting member (170). Here, the second guide member (143a) may have an arc shape and may be provided as a C-shaped frame. At this time, the second guide member (143a) may be formed in the shape of an arc of a circle having a second radius greater than the first radius, and may be formed as a frame having an arc shape with a center angle of about 80° to 110° or 85° to 105°. For example, the second guide member (143a) may be formed as a frame having an arc shape with a center angle of 90° from the second point where the up-and-down movement guide member (142) is coupled to the third point where it is connected (or coupled) to the support member (120). Meanwhile, the center angle of the second guide member (143a) from the second point to the third point may be variously changed within a range of 80° to 110°.

[0079] And the up-and-down movement guide part (142) may further include a first guide rotation part (142b) that allows the first guide member (142a) to rotate in the up-and-down direction, and the left-right movement guide part (143) may further include a second guide rotation part (143b) that allows the second guide member (143a) to rotate in the left-and-right direction. The first guide rotation part (142b) may allow the first guide member (142a) to rotate in the up-and-down direction, and may be connected to one end of the first guide member (142a) (i.e., the second point) to rotate (the other end of) the first guide member (142a) in the up-and-down direction around the one end of the first guide member (142a). Here, the first guide rotation part (142b) may cause the first guide member (142a) to rotate in the up-and-down direction by the magnetic force of the trainer (10), or may cause the arm and / or shoulder of the trainer (10) to rotate in the up-and-down direction by using a separate driving force such as a (first) driving part to rotate the first guide member (142a) in the up-and-down direction. At this time, the first guide member (142a) may rotate in the up-and-down direction within a predetermined angle range (for example, 180° to 270° or 180° to 360°).

[0080] The second guide rotation part (143b) can rotate the second guide member (143a) in the left-right direction, and is connected to one end of the second guide member (143a) (i.e., the third point) to rotate the second guide member (143a) (the other end) in the left-right direction with the one end of the second guide member (143a) as an axis. Here, the second guide rotation part (143b) can rotate the second guide member (143a) in the left-right direction by the magnetic force of the trainee (10), or can rotate the second guide member (143a) in the left-right direction by using a separate driving force such as a (second) driving part, thereby rotating the arm and / or shoulder of the trainee (10) in the left-right direction. At this time, the second guide member (143a) can rotate in the left and right directions within a predetermined angle range (e.g., 180° to 270° or 180° to 360°).

[0081] In this case, one end of the first guide member (142a) is rotatably coupled to the other end (i.e., the second point) of the second guide member (143a) through the first guide rotation part (142b) so as to be rotatably in the vertical direction, and the other end (i.e., the first point) of the first guide member (142a) is connected (or coupled) to the arm fixing part (141) so as to rotate in the vertical direction, thereby rotating the arm fixing part (141) in the vertical direction. In addition, one end of the second guide member (143a) is rotatably coupled to the support part (120) through the second guide rotation part (143b) so as to be rotatably in the left-right direction, and the other end of the second guide member (143a) is connected to one end of the first guide member (142a) so as to rotate in the left-right direction, thereby rotating the first guide member (142a) in the left-right direction. Here, as the first guide member (142a) rotates in the left-right direction, the arm fixing member (141) can also rotate in the left-right direction.

[0082] At this time, the first guide member (142a) may be arranged on the inside of the second guide member (143a) so as to overlap with the second guide member (143a) and not collide with each other, and the first guide member (142a) and the second guide member (143a) may be combined to form a concentric spherical motion trajectory and may be combined to have the same center of rotation. To this end, the first guide member (142a) is formed in an arc shape of a circle having a first radius smaller than that of the second guide member (143a), and is arranged on the inside of the second guide member (143a), so that the first guide member (142a) can rotate (or circularly move) independently from the second guide member (143a) without contacting or colliding with the second guide member (143a) while being combined with the second guide member (143a).

[0083] Meanwhile, in cases where it is difficult for the trainee (10) to move by magnetic force, the first guide member (142a) and the second guide member (143a) can be rotated at a predetermined angle and speed to enable shoulder movement of the trainee (10). By independently rotating the first guide member (142a) and the second guide member (143a) through the first driving unit and the second driving unit, shoulder training can be performed that follows the shoulder movement of the trainee (10) along any path on a three-dimensional spherical surface. At this time, by independently rotating the first guide member (142a) and the second guide member (143a) through the first driving unit and the second driving unit, the range of shoulder movement of the trainee (10) can also be limited. However, in such cases, a problem may occur in which the first guide member (142a) and the second guide member (143a) rotate beyond the range in which the trainer's (10) shoulder can move due to malfunction of the first driving unit and the second driving unit.

[0084] Accordingly, in order to limit the rotation range of the first guide member (142a) and the second guide member (143a), the up-and-down movement guide member (142) may further include an up-and-down rotation stopper (142c) that limits the up-and-down rotation angle of the arm fixing member (141), and the left-and-right movement guide member (143) may further include a left-and-right rotation stopper (143c) that limits the left-and-right rotation angle of the up-and-down movement guide member (142). The up-and-down rotation stopper (142c) may limit the up-and-down rotation angle of the arm fixing member (141) and may limit the rotation range of the first guide member (142a) (the other end). Here, the up-and-down rotation stopper (142c) may be provided in an arc shape and may be installed on the other end of the first guide rotation part (142b) and / or the second guide member (143a) so as to be in contact with one end of the first guide member (142a). For example, the up-and-down rotation stopper (142c) may be provided in a semicircular arc shape, and in this case, the first guide member (142a) may have a rotation range of about 180°.

[0085] The left-right rotation stopper (143c) can limit the left-right rotation angle of the up-and-down movement guide part (142) and thus limit the left-right rotation angle of the arm fixing part (141), and can limit the rotation range of the second guide member (143a) (the other end). Here, the left-right rotation stopper (143c) can be provided in an arc shape and can be installed on the second guide rotation part (143b) and / or the support part (120) so as to be in contact with one end of the second guide member (143a). For example, the left-right rotation stopper (143c) can be provided in a semicircular arc shape, and in this case, the second guide member (143a) can have a rotation range of about 180°.

[0086] When the rotation range of the first guide member (142a) and the second guide member (143a) is limited by the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c), the ends of the first guide member (142a) and the second guide member (143a) that come into contact with the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) may be provided to have a curved surface.

[0087] Here, the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can change the rotation limit angle depending on the selection of either the left or the right side. The shoulder training device (100) of the present invention can train both shoulders (i.e., the left shoulder and the right shoulder) of the trainee (10) depending on the position where the backrest (130) is provided, and the rotation directions of the first guide member (142a) and the second guide member (143a) can be reversed depending on the position where the backrest (130) is provided. Accordingly, the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can be provided so as to be able to change the rotation limit angle, and the rotation limit angle can be changed depending on the selection of either the left or the right side.

[0088] For example, depending on the direction of the shoulder to be trained (or whether it is the left shoulder or the right shoulder), the installation positions of the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can be changed to allow training of both shoulders with one shoulder exercise guide unit (140). At this time, the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can be provided to be detachable from the first guide rotation unit (142b) and the second guide rotation unit (143b) (or the second guide member and the support unit), and the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can be provided to allow movement (or change) of the (installation) positions in the first guide rotation unit (142b) and the second guide rotation unit (143b). When attaching and detaching the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c), a plurality of installation grooves for installing the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) are provided in the first guide rotation part (142b) and the second guide rotation part (143b) (or the second guide member and the support part), so that the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) can be installed according to the shoulder direction to be trained.

[0089] The shoulder training device (100) according to the present invention may further include a control unit (not shown) that controls the rotation limit angles of the up-down rotation stopper (142c) and the left-right rotation stopper (143c) according to the selection of one of the sides, thereby providing a movement pattern corresponding to the shoulder of each side.

[0090] The control unit (not shown) can control the rotation limit angles of the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) respectively according to the selection of one of the above sides, thereby providing a movement pattern corresponding to the shoulder of each side. At this time, the control unit (not shown) can control (or adjust) the rotation limit angles of the up-and-down rotation stopper (142c) and the left-and-right rotation stopper (143c) respectively according to whether the left shoulder is selected (or) the right shoulder is selected, thereby providing a movement pattern suitable for the shoulder of each side.

[0091] For example, the control unit (not shown) can limit the rotation ranges of the first guide member (142a) and the second guide member (143a) through the up-and-down rotation stopper (142c) and the left-right rotation stopper (143c) depending on the direction of the shoulder to be trained. Here, the rotation ranges of the first guide member (142a) between the left shoulder and the right shoulder can be symmetrical (or inverted) with respect to the up-and-down direction, and the rotation ranges of the second guide member (143a) can be symmetrical (or inverted) with respect to the left-and-right direction. For example, when the rotation range (in the up-and-down direction) of the first guide member (142a) during training of the left shoulder is about 0° to 180° (based on the upward direction), the rotation range (in the up-and-down direction) of the first guide member (142a) during training of the right shoulder can be about 0° to -180° (based on the upward direction). And when the rotation range (in the left-right direction) of the second guide member (143a) during training of the left shoulder is about -80° to 100° (based on the front), the rotation range (in the left-right direction) of the second guide member (143a) during training of the right shoulder may be about -100° to 80° (based on the front). Here, the rotation angle (in the up-down direction) of the first guide member (142a) is 0° at the top and the angle increases toward the bottom, and depending on the direction, one side (for example, the front) may be represented as + and the opposite side (for example, the rear) as -. In addition, the rotation angle (in the left-right direction) of the second guide member (143a) is 0° at the front and the angle increases toward the rear, and depending on the direction, the left side may be represented as + and the right side as -. Through this, the first guide member (142a) and the second guide member (143a) can be prevented from rotating beyond the range of movement of each shoulder, thereby providing effective shoulder training without placing a burden on the shoulders of the trainee (10).

[0092] Meanwhile, the control unit (not shown) may control at least one of the rotation speed, rotation acceleration, rotation position, rotation direction, rotation range, or rotation angle of the first guide member (142a) and the second guide member (143a) and the training pattern (e.g., the exercise pattern) of the trainee (10). In addition, the control unit (not shown) may detect the direction of the shoulder to be trained through a detection unit such as a sensor, and limit the rotation range of the first guide member (142a) and the second guide member (143a) through the up-and-down rotation stopper (142c) and the left-right rotation stopper (143c) according to the detected shoulder direction.

[0093] The arm fixing member (141) may include a fixing member (141a) that is attachable and detachable to one arm; a first rotating member (141b) that is connected to the fixing member (141a) and rotates the fixing member (141a) left and right; and a second rotating member (141c) that is connected to the first rotating member (141b) and rotates the fixing member (141a) up and down together with the first rotating member (141b). The fixing member (141a) may be attachable and detachable to one arm and may wrap around a portion of the one arm. For example, the fixing member (141a) may include a band that is formed so that the arm of the trainee (10) can be put on. The band may be provided so that the arm of the trainee (10) can be put on, may be made of fabric, etc., and may be formed to form a hollow cylinder (or closed loop). In this case, the trainee (10) can perform shoulder training by putting his / her arm on the band. Meanwhile, the band may be formed in a belt shape so as to be able to tie the arm of the trainee (10), and in this case, the band (520) may include a belt member and a fastening member installed on the belt member so as to be able to tie the arm of the trainee (10), and the belt member can be tied to the arm of the trainee (10) according to the arm thickness using the fastening member.

[0094] The first rotating member (141b) is connected to the fixed member (141a) and can rotate the fixed member (141a) left and right, and can fix the arm of the trainee (10) wearing (or mounting) the fixed member (141a) to the arm fixing member (141) without causing any discomfort (or burden) to the arm of the trainee (10).

[0095] The second rotating member (141c) is connected to the first rotating member (141b) and can rotate the fixed member (141a) in the up-and-down direction (and / or the front-back direction) together with the first rotating member (141b), and, like the first rotating member (141b), can allow the arm of the trainee (10) wearing the fixed member (141a) to be fixed to the arm fixing member (141) without causing discomfort to the arm of the trainee (10).

[0096] The arm of the trainee (10) may not only have different thicknesses depending on the location, but also the line connecting the center of the arm from the part (or location) of the arm where the fixed member (141a) is mounted (or attached) to the shoulder may not be a straight line. Therefore, if the fixed member (141a) is mounted on the arm of the trainee (10) without the first rotating member (141b) and / or the second rotating member (141c), the extension direction of the arm (or the direction of the line connecting the center of the arm) and the extension direction of the fixed member (141a) (or the direction of the line connecting the center of the fixed member) do not match, and thus the trainee (10) may feel discomfort in the arm.

[0097] Accordingly, the fixed member (141a) can be selectively rotated in the up-and-down direction and the left-and-right direction through the first rotating member (141b) and the second rotating member (141c) so that the extension direction of the fixed member (141a) can be made to match the extension direction of the arm of the trainee (10) as much as possible, and thus the arm of the trainee (10) can be fixed to the arm fixing member (141) so that there is no discomfort in the arm of the trainee (10). Meanwhile, the fixed member (141a) may include a support plate that supports the arm of the trainee (10), and the first rotating member (141b) may rotate the fixed member (141a) in the up-and-down direction so that the support surface of the support plate faces upward so that the support plate can support the arm from under the arm, whether it is the left or right arm of the trainee (10). Accordingly, the support plate can support the arm from under the arm.

[0098] In addition, the arm fixing member (141) may further include a moving member (141d) that is connected to the fixing member (141a) and moves the fixing member (141a) in a direction intersecting the left-right direction. The moving member (141d) is connected to the fixing member (141a) and can move the fixing member (141a) in a direction intersecting the left-right direction (for example, forward-backward direction), and the direction of movement of the fixing member (141a) by the moving member (141d) may also intersect the up-down direction and may be the same as (or parallel to) the arm extension direction of the trainee (10).

[0099] In a case where the arm of the trainee (10) is significantly bent or is lumpy due to muscles, even if the fixed member (141a) is selectively rotated in the up-and-down direction and the left-right direction through the first rotating member (141b) and the second rotating member (141c), it is difficult to match the extension direction of the fixed member (141a) with the extension direction of the arm of the trainee (10). Therefore, the fixed member (141a) can be moved in the extension direction of the arm of the trainee (10) through the moving member (141d) so that the line connecting the centers of the arms can be as straight as possible. In addition, the attachment (or attachment) portion (or part) of the fixed member (141a) on the arm of the trainee (10) can be changed through the moving member (141d). Through this, the arm of the trainee (10) can be fixed to the arm fixing member (141) so that the arm of the trainee (10) is as comfortable as possible.

[0100] Meanwhile, even if the shoulder rotation center of the trainer (10) and the rotation center (point) of the shoulder movement guide (140) do not coincide, the fixed member (141a) may be moved in the direction of arm extension of the trainer (10) through the transfer member (141d) so as not to put a burden on the trainer's shoulder and / or other body parts (or portions).

[0101] Accordingly, the shoulder training device (100) according to the present invention further includes a moving member (141d) that can move the fixed member (141) in a direction intersecting the left and right directions, in addition to the first rotating member (141b) and the second rotating member (141c) that rotate the fixed member (141a) in the left-right and up-down directions, thereby finely adjusting the position of the arm and / or shoulder of the trainee (10) to align the shoulder rotation center (or shoulder joint) of the trainee (10) and the rotational center (point) of the shoulder movement guide unit (140) as much as possible. In addition, even if the shoulder rotation center of the trainee (10) and the rotational center (point) of the shoulder movement guide unit (140) do not align, the shoulder and / or other body parts (or portions) of the trainee (10) can be minimized from being burdened.

[0102] Accordingly, it is possible to prevent the occurrence of unexpected injuries during (rehabilitation) training (or rehabilitation treatment) of the shoulder joint and / or arm muscles of the trainee (10), and at the same time, significantly improve the training (or rehabilitation) effect of the trainee through shoulder training.

[0103] In addition, since a single shoulder exercise guide unit (140) can provide training to each shoulder without distinction between the left and right shoulders, and the structure of the arm fixing unit (141) including multiple joints can be omitted, the structural complexity of the shoulder training device (100) can be reduced. In addition, as the structural complexity is improved, the manufacturing productivity of the shoulder training device (100) can be improved, and the manufacturing cost can also be reduced. In addition, a shoulder training device (100) having a compact and lightweight structure that can efficiently utilize the installation space can be provided.

[0104] Meanwhile, the shoulder training device (100) according to the present invention may further include a rotating part (not shown) that rotates the backrest (130) around the central axis of the support part (120).

[0105] The rotating part (not shown) can rotate the backrest (130) around the central axis of the support part (120), and only the backrest (130) can rotate around the seat part (110), or the backrest (130) can also rotate together with the seat part (110) as it rotates around the central axis of the support part (120). Through this, the position of the backrest (130) can be changed with respect to the shoulder movement guide part (140) to one side or the other in the first direction.

[0106] And the shoulder training device (100) of the present invention may further include an operating unit (not shown) for manipulating and displaying training conditions such as exercise patterns. The operating unit (not shown) may display a control situation and manipulate at least one of rotational speed, rotational acceleration, rotational direction, rotational angle, and training pattern of the trainee (10).

[0107]

[0108] In this way, in the present invention, the position of the shoulder exercise guide part can be changed to one side or the other of the first direction of the backrest, and accordingly, the left shoulder or the right shoulder can be selected and shoulder training can be performed according to the selection, and the shoulder to be trained can be switched between the left shoulder and the right shoulder. At this time, by moving the shoulder exercise guide part in the first direction so as to come closer to the backrest through the guide moving part, training can be selectively provided for the left shoulder and the right shoulder without being blocked with a single shoulder exercise guide part. In addition, by precisely adjusting the position of the shoulder exercise guide part to a position that does not put a strain on the trainee's shoulder through the guide height adjustment part and the guide moving part in response to the trainee's body structure and posture, it is possible to provide a natural exercise pattern suitable for the trainee without putting a strain on the trainee's shoulder, and to enable optimal shoulder training suitable for the trainee. In addition to the first and second rotation members that rotate the fixed member left-right and up-down, the arm fixing member further includes a moving member that can move the fixed member in a direction crossing the left-right and up-down directions, thereby maximizing the alignment of the trainee's shoulder rotation center with the rotational center of the shoulder movement guide member. Furthermore, even if the trainee's shoulder rotation center and the rotational center of the shoulder movement guide member do not align, the least amount of strain can be placed on the trainee's shoulder and / or other body parts. Accordingly, unexpected injuries to the trainee's shoulder joint and / or arm muscles during training can be prevented, and at the same time, the training effect of the trainee through shoulder training can be significantly improved. In addition, since a single shoulder movement guide member can provide training to each shoulder selectively without distinction between the left and right shoulders, and since the structure of the arm fixing member including multiple joints can be eliminated, the structural complexity of the shoulder training device can be reduced. In addition, as the structural complexity is improved, the manufacturing productivity of the shoulder training device can be improved, and the manufacturing cost can also be reduced.
