[0066] (Example 3-4) The present invention relates to a chair for body shape correction, and in any one selected from Examples 1-4 and 3-2, the rotary power motor and the reducer are formed at the lower part of the chair body (20).

[0067] The rotary motion power unit (110) of the present invention includes a rotary motion power motor unit (111) that generates rotary force, and a rotary motion power shaft (112) that transmits rotary force from the rotary motion power motor unit (111) to the angle motion control unit (120), thereby enabling the angle motion control unit (120) to perform a horizontal rotational motion.

[0068] The rotary motion power motor unit (111) may be composed of a rotary motion power motor that generates rotary force and a reducer that controls the rotational speed of the rotary motion power motor. The reducer can not only increase the torque of the rotary force supplied to the angular motion control unit (120) by controlling the rotational speed of the rotary motion power motor, but can also control the rotational speed of the circular rotation of the seating unit (10).

[0069] At this time, it is preferable that the rotary motion power motor part (111) be formed at the bottom of the chair body (20) to prevent user discomfort and safety accidents due to contact with the user, and it is preferable that the rotary motion power shaft (112) be formed to penetrate the chair body (20) upward from the rotary motion power motor part (111).

[0070] The rotary motion power shaft (112) is formed to protrude upward from the rotary motion power motor unit (111) and be coupled with the angle motion control unit (120), and is formed to be capable of axial rotation in the horizontal direction. In this way, the rotary motion power shaft (112) transmits the rotational force of the rotary motion power motor unit (111) as a horizontal rotational force, thereby causing the angle motion control unit (120) to rotate in the horizontal direction.

[0075] (Example 4-4) The present invention relates to a chair for body shape correction, and in Example 4-3, the moving path is formed diagonally in the longitudinal direction of the angle motion control unit body (121).

[0076] (Example 4-5) The present invention relates to a chair for body shape correction, and in Example 4-3, the angle motion movement projection (122) and the angle motion movement forming part (123) in which the angle motion movement projection (122) moves while being engaged with each other are formed on both sides in the width direction of the angle motion control part body (121).

[0077] (Example 4-6) The present invention relates to a chair for body shape correction, and in Example 4-1, the rotational motion power shaft (112) is formed so that the cross-section that comes into contact with the angle motion control body (121) forms a straight line.

[0078] The angle motion control unit (120) of the present invention includes an angle motion control unit body (121), an angle motion movement protrusion (122), and an angle motion movement forming unit (123).

[0079] The angle motion control body (121) is coupled to the upper portion of the rotation motion power shaft (112) and rotates together with the axial rotation of the rotation motion power shaft (112), but is coupled so as to be rotatable in one direction. Through this, the angle motion control body (121) can rotate to control the inclination of the seating portion (10).

[0080] The angular motion movement protrusion (122) is formed by protruding in the width direction from one longitudinal side of the angular motion control body (121).

[0081] The angle motion movement forming part (123) is formed to control the angle of the angle motion control part body (121) by moving the angle motion movement protrusion (122) by lifting in the up and down direction by the angle motion power part (130). That is, the angle motion movement forming part (123) forms a movement path in which the angle motion movement protrusion (122) is engaged and moves, and by lifting the angle motion movement forming part (123) in the up and down direction, the angle motion movement protrusion (122) engaged therewith is moved, and by controlling the inclination angle of the angle motion control part body (121) accordingly, the inclination of the seating part (10) can be controlled.

[0083] As described above, the angle motion control unit (120) transmits rotational force to enable circular rotation of the seating unit (10), and can control the inclination of the seating unit (10), thereby enabling circular rotation while the seating unit (10) is tilted at a selected angle.

[0084] At this time, it is preferable that the angle motion movement projection (122) and the angle motion movement forming part (123) in which the angle motion movement projection (122) moves while being engaged are formed as a pair on both sides of the width direction of the angle motion control body (121), and it is preferable that the angle control is easily controlled as the angle motion control body (121) rotates accordingly.

[0085] In addition, the rotary motion power shaft (112) is preferably formed so that the lower part has a circular cross-section and rotates around the axis, and the upper part has a straight cross-section that contacts the angle motion control body (121) in the direction in which it is tilted, thereby accurately transmitting the rotational force and performing a supporting and guiding role when the angle motion control body (121) is tilted.

[0088] (Example 5-2) The present invention relates to a chair for body shape correction, and in Example 5-1, the angle motion power motor unit (131) includes an angle motion power motor that generates rotational force.

[0089] (Example 5-3) The present invention relates to a chair for body shape correction, and in Example 5-1, the second angle operation power gear (133) is positioned horizontally with the first angle operation power gear (132), and the rotation operation power shaft (112) is formed so that it is positioned inside.

[0090] (Example 5-4) The present invention relates to a chair for body shape correction, and in Example 5-3, screw threads are formed on the outer surface of the angle motion lifting part (134) and the inner surface of the second angle motion power gear (133) to interlock with each other and move the angle motion lifting part (134) in the up and down direction.

[0091] (Example 5-5) The present invention relates to a chair for body shape correction, and in Example 5-1, the angle motion power unit (130) includes a power transmission plate (135) to which the angle motion lifting unit (134) is coupled at the bottom and the angle motion moving forming unit (123) is coupled at the top.

[0092] (Example 5-6) The present invention relates to a chair for body shape correction. In Example 5-5, the power transmission plate (135) is formed in a plate shape having a certain area in the horizontal direction.

[0093] (Example 5-7) The present invention relates to a chair for body shape correction, and in Example 5-6, the power transmission plate (135) is formed in a vertical direction and includes a power transmission plate guide part (135-1) that guides the movement of the power transmission plate (135).

[0094] (Example 5-8) The present invention relates to a chair for body shape correction, and in any one selected from Examples 1-4 and 5-1, the angle motion power motor is formed at the lower part of the chair body (20).

[0095] The angle operation power unit (130) of the present invention includes an angle operation power motor unit (131), a first angle operation power gear (132), a second angle operation power gear (133), and an angle operation lifting unit (134).

[0096] The angle operation power motor unit (131) generates rotational force for the operation of the angle operation control unit (120) described above. The angle operation power motor unit (131) includes an angle operation power motor formed as a motor that generates rotational force. At this time, the angle operation power motor is preferably formed at the lower part of the chair body (20) to prevent interference with the user and safety accidents, and is preferably formed to transmit rotational force to the first angle operation power gear (132) by a shaft protruding from the upper part of the chair body (20).

[0097] The first angle operating power gear (132) is formed as a gear that is combined with the angle operating power motor unit (131) and is formed to enable horizontal axis rotation.

[0098] The second angle operation power gear (133) is positioned horizontally with respect to the first angle operation power gear (132), and is formed so that the rotational operation power shaft (112) is positioned inside, and is formed so as to mesh with the first angle operation power gear (132), so that it receives the rotational force of the first angle operation power gear (132) and rotates the axis in the horizontal direction.

[0099] The angle motion lifting part (134) is formed to move up and down according to the rotation of the second angle motion power gear (133) and to move the angle motion movement forming part (123) up and down. At this time, screw threads are formed on the outer surface of the angle motion lifting part (134) and the inner surface of the second angle motion power gear (133) to mesh with each other and move the angle motion lifting part (134) up and down. Through this, as the second angle motion power gear (133) rotates, the angle motion lifting part (134) meshed with it moves up and down through the screw threads, thereby allowing the angle motion control part (120) to control the angle of the seating part (10).

[0100] At this time, the angle motion power unit (130) includes a power transmission plate (135) to which an angle motion lifting unit (134) is coupled at the bottom and an angle motion movement forming unit (123) is coupled at the top. The power transmission plate (135) is formed to have a certain area in the horizontal direction, thereby enabling the angle motion lifting unit (134) to move uniformly up and down, thereby enabling precise angle control.

[0101] In addition, the power transmission plate (135) includes a power transmission plate guide portion (135-1) formed vertically to guide the movement of the power transmission plate (135) for uniform vertical movement. At least one power transmission plate guide portion (135-1) is formed, and more preferably, four power transmission plate guide portions are formed to enable uniform movement of the power transmission plate (135) having a constant area in the horizontal direction.

[0102] As described above, the power transmission plate (135) moves up and down, and accordingly, the angular motion movement forming part (123) tilts, and accordingly, the angular motion movement protrusion (122) moves diagonally, causing the angular motion control part body (121) to tilt. Through this, the angular motion control part body (121) tilts, causing the axis of the circular rotation part (140), particularly the axis of the circular rotation axis (141) described later, to tilt, and the rotational motion power shaft (112) rotates to perform circular rotation (spherical rotation).

[0103] At this time, the up-and-down movement of the power transmission plate (135) can be formed not only by the gear method of the angle-actuating power unit (130), but also by two or more motors being installed to enable movement in the up-and-down direction.

[0105] (Example 6-1) The present invention relates to a chair for body shape correction, and in Example 5-1, the circular rotation part (140) includes a circular rotation shaft (141) which is connected on one side to the upper inner side of the angle motion control part body (121) by a bearing and on the other side is connected to the seating part (10).

[0106] (Example 6-2) The present invention relates to a chair for body shape correction, and in Example 6-1, the circular rotation part (140) includes a circular rotation horizontal axis (142) formed by horizontally penetrating the circular rotation axis (141), a unit bearing (143) formed at both ends of the circular rotation horizontal axis (142), and a bearing fixing plate (145) connected through the unit bearing (143) to support the circular rotation horizontal axis (142).

[0107] (Example 6-3) The present invention relates to a chair for body shape correction, and in Example 6-2, the above-mentioned circular rotation part (140) includes a support shaft (144) connected to the bearing fixing plate (145) through the above-mentioned unit bearing (143) formed by intersecting the above-mentioned circular rotation horizontal axis (142) at a right angle in the horizontal direction.

[0108] (Example 6-4) The present invention relates to a chair for body shape correction, and in any one of Examples 1-2 and 6-3, the body shape correction operation part (100) further includes a load support part (150) that is coupled to the chair body (20) and the support shaft (144) to support a load.

[0109] (Example 6-5) The present invention relates to a chair for body shape correction, and in Example 6-3, the bearing fixing plate (145) is formed in a ring shape selected from among a circle and a square shape, which is connected to the unit bearing (143) on the outside of the circular rotation shaft (141).

[0110] The circular rotation part (140) of the present invention is formed to rotate the seating part (10) in a tilted state by the angle motion control part body (121), and includes a circular rotation axis (141).

[0111] The circular rotation shaft (141) is formed by connecting one side to the upper inner side of the angular motion control body (121) by a bearing, and connecting the other side to the seating part (10).

[0112] At this time, the circular rotation part (140) includes a circular rotation horizontal axis (142) formed by horizontally penetrating the circular rotation axis (141), unit bearings (143) formed at both ends of the circular rotation horizontal axis (142), and a bearing fixing plate (145) that supports the circular rotation horizontal axis (142) through the unit bearings (143).

[0113] This prevents the circular rotation axis (141) from rotating horizontally, while allowing it to rotate using the bearing fixing plate (145).

[0114] In addition, the circular rotation part (140) includes a support shaft (144) connected to a bearing fixing plate (145) through a unit bearing (143) formed by intersecting the circular rotation horizontal axis (142) at a right angle to the horizontal direction.

[0115] At this time, the support shaft (144) can support the load transmitted through the seating part (10) by the load support member (150) that is combined with the support shaft (144) and supports the load.

[0116] That is, the bearing fixing plate (145) is formed in a ring shape such as a square or circle on the outside with the circular rotation axis (141) as the center, and four unit bearings (143) are vertically crossed and fixedly installed on the upper or lower side of the bearing fixing plate (145), and two of the unit bearings (143) are connected to a support shaft (144) and connected to the chair body (20), thereby supporting the bearing fixing plate (145).

[0117] Through this, the circular rotation shaft (141) is driven like a seesaw in the up-and-down direction at both ends, while the bearing fixing plate (145) is driven like a seesaw on all four sides sequentially to rotate the seating part (10).

[0118] As described above, when a user sits on the seat (10) and operates, the circular rotation part (140) supports the load through the unit bearing (143) formed on the support shaft (144) coupled with the load support part (150), thereby minimizing the transfer of the load to the angle motion control part (120) coupled with the circular rotation part (140), thereby preventing damage and breakage.

[0119]

[0120] (Example 7-1) The present invention relates to a chair for body shape correction, and in Example 6-1, the body shape correction operation part (100) includes a limit sensor part (160) including limit sensors formed to be spaced apart in the vertical direction to control the vertical movement of the angle operation lifting part (134).

[0121] (Example 7-2) The present invention relates to a chair for body shape correction, and in Example 7-1, the limit sensor includes an upper limit sensor (161) located at the top, and a lower limit sensor (162) located at the bottom and moving up and down.

[0122] (Example 7-3) The present invention relates to a chair for body shape correction, and in any one of Examples 5-5 and 7-2, the upper limit sensor (161) and the lower limit sensor (162) are formed at the end of the vertical movement length of the power transmission plate (135) so as to be in contact with each other according to the movement of the power transmission plate (135).

[0123] (Example 7-4) The present invention relates to a chair for body shape correction, and in Example 7-3, the limit sensor part (160) includes a limit sensor fixing part (163) that fixes an upper limit sensor (161) and a lower limit sensor (162).

[0124] The body shape correction operation unit (100) of the present invention includes a limit sensor unit (160) formed to control the up and down movement of the angle operation lifting unit (134). The limit sensor unit (160) is formed to control the inclination by controlling the up and down movement of the angle operation lifting unit (134). The limit sensor unit (160) includes limit sensors formed to be spaced apart from each other in the up and down direction, and the limit sensors include an upper limit sensor (161) located at the upper portion and a lower limit sensor (162) located at the lower portion.

[0125] At this time, the upper limit sensor (161) and the lower limit sensor (162) are formed at the end of the vertical movement length of the power transmission plate (135), and are formed so as to be in contact with the movement of the power transmission plate (135).

[0126] That is, the power transmission plate (135) moves together with the up-and-down movement of the angular motion lifting unit (134), and when it moves upward, it comes into contact with the upper limit sensor (161), and when it moves downward, it comes into contact with the lower limit sensor (162), thereby allowing the limit sensor unit (160) to control the movement of the angular motion lifting unit (134). In other words, the upper and lower limits of the up-and-down movement of the angular motion lifting unit (134) can be controlled.

[0127] In addition, the limit sensor unit (160) may include a limit sensor fixing unit (163) that fixes the upper limit sensor (161) and the lower limit sensor (162).

[0128] Of course, the configuration of the limit sensor unit (160) described above is a preferred embodiment, and it is not limited to the configuration described above, and various shapes and position embodiments are possible as long as the control of the up-down movement of the angular motion lifting unit (134) is easy.

[0129]

[0130] (Example 8-1) The present invention relates to a chair for body shape correction, and in Example 6-1, the body shape correction operation unit (100) includes a rotation speed measuring sensor unit (170) formed as an optical sensor that measures the rotation speed.

[0131] (Example 8-2) The present invention relates to a chair for body shape correction, and in Example 8-1, the rotation speed measuring sensor unit (170) includes a direction change sensor unit (171) that measures the rotation speed in one direction and controls rotation in the other direction in response thereto.

[0132] (Example 8-3) The present invention relates to a chair for body shape correction, and in Example 8-1, the rotation speed measuring sensor unit (170) includes a tilt control sensor unit (172) formed to control the movement of the angle motion lifting unit (134) in the up-and-down direction according to the measurement of the rotation speed.

[0133] The body shape correction operation unit (100) of the present invention includes a rotation speed measuring sensor unit (170) formed by an optical sensor that measures the rotation speed.

[0134] The rotation speed measuring sensor unit (170) includes a direction change sensor unit (171) formed to measure the rotation speed in one direction and control the rotation in the other direction in response thereto.

[0135] That is, if it is rotated in one direction, there is a concern that the therapeutic effect may be reduced, and the direction change sensor unit (171) is formed to measure the number of rotations in one direction and controllably operate at the same number of rotations in the corresponding other direction, thereby allowing the user to obtain an equal corrective effect on the left and right sides of the body.

[0136] For example, when rotating 10 times in one direction, the rotation is made 10 times in the other direction according to the measurement, thereby ensuring equal rotation in one direction and the other direction.

[0137] In addition, the rotation speed measurement sensor unit (170) includes a tilt control sensor unit (172) formed to control the movement of the angle operation lifting unit (134) in the up and down direction according to the rotation speed measurement. The tilt control sensor unit (172) measures the rotation speed in one direction or the other from the origin, and can thereby measure the tilt of the angle operation control unit body (121).

[0138] The tilt control sensor unit (172) measures the number of rotations in one direction or the other, and calculates the tilt of the angle motion control unit body (121) accordingly, thereby controlling the movement of the angle motion lifting unit (134) in the up and down direction accordingly.

[0139] That is, the tilt control sensor unit (172) can control the upper and lower limits of movement in the up and down direction of the angle operation lifting unit (134) in the same manner as the limit sensor unit (160) described above. Accordingly, when the control operation is added due to damage or malfunction of the limit sensor unit (160) described above, the tilt sensor unit (172) can control the movement in the up and down direction of the angle operation lifting unit (172) by replacing it.

[0140]

[0141] (Example 9-1) The present invention relates to a chair for body shape correction, and in Example 6-1, the body shape correction operation unit (100) includes an ultrasonic sensor unit (180) including ultrasonic sensors formed to be spaced apart in the vertical direction to control the vertical movement of the angle operation lifting unit (134).

[0142] (Example 9-2) The present invention relates to a chair for body shape correction, and in Example 9-1, the ultrasonic sensor unit (180) includes an upper ultrasonic sensor (181) located above the power transmission plate (135) in the vertical direction and a lower ultrasonic sensor (182) located below, and measures the power transmission plate (135) that is close to it.

[0143] In addition, the body shape correction operation unit (100) includes an ultrasonic sensor unit (180) including ultrasonic sensors formed spaced apart in the vertical direction to control the vertical movement of the angle operation lifting unit (134).

[0144] The ultrasonic sensor unit (180) includes an upper ultrasonic sensor (181) located at the upper side and a lower ultrasonic sensor (182) located at the lower side based on the vertical direction of the power transmission plate (135), and when they come close to each other as the power transmission plate (135) moves vertically, the position of the power transmission plate (135) is measured, thereby controlling the movement of the angular motion lifting unit (134).

[0145] The ultrasonic sensor unit (180) performs the same operation as the limit sensor unit (160), and measures the position of the power transmission plate (135) using an ultrasonic measurement method rather than a contact method, thereby reducing the risk of damage and breakage and increasing the lifespan.

[0146]

[0147] In addition, the present invention may include a motor resistance sensor that measures the resistance of the rotary motion power motor unit (111). By measuring the motor resistance of the rotary motion power motor unit (111) using the motor resistance sensor, the operation can be controlled to stop in case of overload, thereby preventing the occurrence of safety accidents and increasing the lifespan for use.
