Description

This disclosure relates to an exercise assistance device. Patent Document 1 discloses a device for training joint flexion and extension movements in patients (joint flexion and extension exercise device). The joint flexion and extension exercise device described in Patent Document 1 involves attaching an arm, designed to bend along an axis, to the patient's knee joint. By moving the arm using a motor and ball screw, flexion and extension movements can be performed passively. Patent Document 2 discloses a hip joint stretching device that assists in the opening and closing movement of both legs. The hip joint stretching device described in Patent Document 2 uses a leg-opening lever and a leg-pressing plate to bias the user's legs in the opening direction, allowing for hip joint stretching with minimal load. Furthermore, jiggling exercises are known to be a method for improving pain associated with osteoarthritis of the hip. Japanese Patent Publication No. 2002-315793Japanese Patent Publication No. 2005-211327 This figure shows the overall configuration of the exercise assistance device of the present invention.This is the first figure showing an example of the shape of the seat surface of the present invention.This is a second figure showing an example of the shape of the seat surface of the present invention.This is the first diagram to explain the movement of the hip joint.This is the second diagram to explain the movement of the hip joint.This figure illustrates the movement of the hip joint when using the exercise assistance device of the present invention. The following describes an exercise assistance device according to one embodiment of this disclosure, with reference to the figures. (Overall configuration of the exercise assistance device) Figure 1 shows the overall configuration of the exercise assistance device of the present invention. As shown in Figure 1, the exercise assistance device 1 comprises a base 2 placed on the floor, a seat 3 on which the user sits, a backrest 4 that supports the user's back, and legs 5 that connect the base 2 and the seat 3. The leg portion 5 has a first connecting portion 51 that rotatably connects its lower end 5A to the base portion 2, and a second connecting portion 52 that rotatably connects its upper end 5B to the seat surface 3. In this embodiment, the first connecting portion 51 and the second connecting portion 52 are, for example, ball joints and are rotatable in any direction of 360 degrees. In other embodiments, the first connecting portion 51 and the second connecting portion 52 may be configured to rotate in only one direction. The leg portion 5 can move 360 degrees in all directions around the first connecting portion 51. Similarly, the seat surface 3 can move 360 degrees in all directions around the second connecting portion 52. Furthermore, the leg portion 5 has an extendable portion 53 that expands and contracts in the extension direction (±Z direction in Figure 1). The extendable portion 53 is, for example, a spring. This allows the seat surface 3 to move vertically (in the extension direction of the leg portion 5) in accordance with the user's movements. The backrest 4 is provided with a first fixing part 41 for securing the user's hip joints to the backrest 4 when the user is seated. For example, the first fixing part 41 is a belt-shaped fastener that wraps around the user's hip joints. This allows the seat 3 and backrest 4 to move in accordance with the user's movements, preventing the user's hip joints from lifting away from the seat 3 and backrest 4. As a result, the seat 3 and backrest 4 can stabilize the user's pelvic tilt and hip joint position. Furthermore, the seat surface 3 may be provided with a second fixing part 31 for securing the user's hip joints to the seat surface 3 when the user is seated. For example, the second fixing part 31 is a belt-shaped fastener that wraps around the user's thighs. This more reliably prevents the user's hip joints from lifting away from the seat surface 3 and backrest 4. (Shape of the seat) Figure 2 is a first diagram showing an example of the shape of the seat surface of the present invention. Figure 3 is a second diagram showing an example of the shape of the seat surface according to the present invention. The seat surface 3 may be formed such that the width on the front side (+Y side) is smaller than the width on the rear side (-Y side), as shown in Figure 2 or Figure 3. For example, as shown in Figure 2, the front side (+Y side) of the seat surface 3 may have a rectangular cutout 32A at one end (-X side) and a rectangular cutout 32B at the other end (+X side). In other words, the seat surface 3 is formed in a T-shape when viewed from above (+Z side). Furthermore, as shown in Figure 3, the front side (+Y side) of the seat surface 3 may have a notch 33A formed by cutting out one end (-X side) corner and another notch 33A formed by cutting out the other end (+X side) corner. In other words, the seat sur
