Description

[Technical field]

[0001] The present invention relates to a passive exercise device capable of performing inclined circular motion, eccentric circular motion, or both motions simultaneously. [Background technology]

[0002] A conventional passive exercise device is known from Patent Document 1 below.

[0003] The passive exercise device of Patent Document 1 below is capable of passively exercising the part of the user to be treated placed on the treatment table by inclining and eccentrically rotating the treatment table. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 09-149951 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the passive exercise device of Patent Document 1, the center of rotation of the treatment table cannot be changed, and the treatment table can only move with a constant eccentricity. Therefore, only a constant passive motion can be provided to the part of the user to be treated.

[0006] Furthermore, the inclination of the treatment table cannot be changed, and from this point of view, only a constant passive movement can be provided. [Means for solving the problem]

[0007] The passive exercise device according to the present invention fundamentally solves the problems of the conventional passive exercise devices described above. In brief, the passive exercise device according to the present invention comprises a turntable (7) which rotates on a base (8) by motor drive or manually, a turntable (4) which rotates on the turntable (7), and a treatment table (3) which rotates on the turntable (4), the treatment table (3) is arranged concentrically with the turntable (4) and has a turntable mechanism which rotates freely without being influenced by the rotation of the turntable (4), the turntable (4) rotates together with the turntable (7) and has a configuration in which the center of rotation can slide on a slide rail (6) while the device is stopped, and the treatment table (3) is caused to make an eccentric circular movement in the horizontal direction on the turntable (7), and causes a variety of large and small eccentric circular movements of the target part of the user.

[0008] Preferably, an angle adjuster (5) is provided for the turntable (4) relative to the turntable (7) so that the angle can be arbitrarily set and tilted while the device is stopped, thereby enabling the turntable (4) to perform inclined circular motion at various angles.

[0009] More preferably, a treatment table (1) that operates together with the treatment table (3) is provided on the turntable (4), and an angle adjuster (2) is provided between the treatment table (1) and the treatment table (3) to enable tilting by setting an arbitrary angle while the device is stopped. As a result, when the treatment table (1) makes an eccentric or tilted circular movement together with the treatment table (3), the tilt angle of the treatment table (1) can be made to be a safe tilt angle with respect to the part to be treated.

[0010] More preferably, a support mechanism is provided for maintaining the orientation of the treatment table (1) and the treatment table (3) constant while absorbing the up-down, left-right, front-back, or twisting movements of the treatment table (1) and the treatment table (3) when the device is operated by the functions of each of the parts (9) to (16) in Fig. 1. As a result, the treatment table (1) and the treatment table (3) always support a constant direction during operation. In addition, when the treatment table (3) is used as a treatment table, the mounting bracket (9) in Fig. 1 is turned upside down and installed on the front part of the upper surface of the treatment table (3), so that the treatment table (3) always supports a constant direction. These support mechanisms allow the treatment area to be passively moved safely while maintaining its orientation in one direction. Effect of the Invention

[0011] The present invention, which is configured as described above, has the following effects. According to the passive exercise device of the present invention, the treatment table (3) and the treatment table (1) that is optionally installed can be adjusted to any desired width of the rotation center shift and inclination angle relative to the turntable (7), thereby enabling passive exercise combining eccentric circular motions of various widths and inclination circular motions of various angles, and can perform passive exercises of appropriate inclination circular motions or eccentric circular motions, or both inclination eccentric circular motions simultaneously, in accordance with the part to be treated, such as the foot, buttocks, shoulder blade, wrist, or cervical vertebrae. This is expected to prevent contracture, chronic pain, spasticity, poor circulation, disuse atrophy, etc., caused by general paralysis.

[0012] The inclined circular motion refers to the manner in which the angle of the turntable (4) is adjusted with respect to the turntable (7) by the angle adjuster (5), and the turntable (4) rotates while maintaining the inclined angle, such as the movement of a coin about to fall after being spun. The eccentric circular motion refers to the manner in which the turntable (4) rotates horizontally around the outside of the center of the turntable (7) when the central axis of the turntable (4) is shifted with respect to the turntable (7) by the slide rail (6).

[0013] For example, when the passive exercise device of the present invention is simultaneously operated in an eccentric circular motion in which the central axis of the turntable (4) is shifted relative to the turntable (7) by the slide rail (6) and inclined circular motion in which the angle of the turntable (4) is set relative to the turntable (7) by the angle adjuster (5), and further the angle of the treatment table (1) is set relative to the treatment table (3) by the angle adjuster (2), and when the foot is treated, when the treatment table (1) rotates relative to the turntable (7) to 6 o'clock, 9 o'clock, 12 o'clock, and 3 o'clock, which correspond to the positions of the hour hand of a clock, as shown in each of Figures 2, 3, 4, and 5 (A), the angles of the knee and ankle are stretched as shown in Θ1, Θ2, Θ3, Θ4, Θ5, Θ6, Θ7, and Θ8, as shown in each of Figures 2, 3, 4, and 5 (B).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] BEST MODE FOR CARRYING OUT THE DISCLOSURE A passive exercise device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0016] As shown in Fig. 1, a slide rail 6 is fixedly installed at the center of the upper part of a turntable 7 which is mounted on a base 8 and rotated by a motor or manually. When the device is stopped, the position of the turntable 4 is adjusted by shifting it outward from the concentric center with respect to the turntable 7 using the slide rail 6, thereby enabling eccentric circular motion.

[0017] An angle adjuster 5 is fixedly installed on the sliding portion of the slide rail 6. By arbitrarily setting the angle adjuster 5 while the device is stopped, the rotating plate 4 can perform an inclined circular motion.

[0018] An end portion of the rotating disk 4 is fixed to the upper portion of the angle adjuster 5 .

[0019] The treatment table 3 is installed concentrically above the turntable 4 so that it can rotate freely without being affected by the rotation of the turntable 4. The turntable mechanism allows the treatment table 3 to rotate freely relative to the turntable 4, so that the treatment area can be circularly moved while keeping the direction of the treatment area constant. In addition to passively moving the treatment area with the treatment table 3, the present invention also provides a treatment table 1 that rotates together with the treatment table 3 on the treatment table 3, as described later, and the treatment table 1 can be tilted relative to the treatment table 3, so that the treatment table 1 can be used as the treatment table to perform tilted circular movement of the treatment area while maintaining a safe tilt angle.

[0020] An angle adjuster 2 is fixed to an end portion of the treatment table 3. Furthermore, the treatment table 1 is fixed to the top of the angle adjuster 2 at the end portion of the treatment table 1. By arbitrarily setting the angle adjuster 2 while the device is stopped, the treatment table 1 can perform passive movement while maintaining the angle set by the angle adjuster 2.

[0021] The mounting bracket 9 is fixed at the center of the opposite end of the lower surface of the treatment table 1 to the end where the angle adjuster 2 is fixed, and the upper end of the slide pipe 12 is axially fixed to the mounting bracket 9 with a screw 10 and a nut 11. Alternatively, when the treatment table 3 is used as the treatment table, the mounting bracket 9 is turned upside down and fixed to the front part of the upper surface of the treatment table 3, and the slide pipe 12 is axially fixed in the same manner. Furthermore, the mounting bracket 16 is fixed to the front part of the upper surface of the main body base 8, and the lower end of the slide pipe 13 is axially fixed with a screw 14 and a nut 15. Furthermore, the slide pipe 13 is inserted into the slide pipe 12 to form a cylinder structure. The mounting bracket 9 is, for example, U-shaped as used for the rear wheel part of a dolly, and the slide pipe 12 fixed to the mounting bracket 9 can move freely in the vertical direction but not in the horizontal direction. Furthermore, the mounting bracket 16 is U-shaped as used for the front wheel part of a dolly, but can rotate freely, so it can rotate freely left and right in addition to up and down.

[0022] The mounting brackets 9 and 16, and the slide pipes 12 and 13 ensure that the direction of the treatment tables 1 and 3 is always maintained constant toward the mounting bracket 16, even when the positions of the treatment tables 1 and 3 change forward, backward, left or right due to eccentric circular motion, and even when twisting and up and down movement occurs due to inclined circular motion.

[0023] In the present invention, the support mechanism for always maintaining the treatment tables 1 and 3 in a constant direction can be configured so that the treatment tables 1 and 3 always maintain a constant direction by rotating the treatment tables 3 in the opposite direction to the turntable 4 at the same speed using a gear or motor, etc., depending on the implementation.

[0024] The treatment tables 1, 3 and the turntable 4 can perform concentric circular motion and eccentric circular motion of various widths relative to the turntable 7 by the slide rails 6, and tilted circular motion of various angles by the angle adjuster 5. Therefore, by adjusting the angle adjuster 5 and the slide rails 6, either the tilted circular motion or the eccentric circular motion, or both can be passively moved at the same time.

[0025] As shown in FIG. 6, when the treatment table 1 is used as a treatment table, when tilted circular motion or eccentric circular motion is performed relative to the turntable 7, the angle adjuster 2 cooperates with the angle adjuster 5 to provide, for example, an appropriate dorsiflexion angle of the ankle when the treatment table 1 is positioned at 6 o'clock relative to the turntable 7, and when the treatment table 1 is positioned at 12 o'clock relative to the turntable 7, for example, excessive plantar flexion of the ankle is prevented, allowing safe tilted circular motion and eccentric circular motion.

[0026] That is, when the treatment table 1 is positioned at the 6 o'clock position relative to the turntable 7 as shown in Figure 6(A) and when the treatment table 1 is positioned at the 12 o'clock position relative to the turntable 7 as shown in Figure 6(B), the inclination direction of the treatment table 3 relative to the turntable 7 is exactly opposite. Therefore, if the angle of the treatment table 1 is adjusted to Θ9 relative to the treatment table 3 using the angle adjuster 2 and the angle of the turntable 4 is adjusted to Θ10 relative to the turntable 7 using the angle adjuster 5, as shown in Figure 6(A), the treatment table 1 acts on the treatment area at an inclination angle relative to the turntable 7 which is the sum of Θ9 and Θ10, whereas as shown in Figure 6(B), the treatment table 1 is inclined at an angle relative to the turntable 7 which is Θ9 minus Θ10.

[0027] Therefore, for example, when treating the foot, when the foot is at the 6 o'clock position, the foot will be at a moderate dorsiflexion angle, while when the foot is at the 12 o'clock position, the ankle will be at a moderate plantar flexion angle, allowing safe passive movement.
