[0015]
Furthermore, the thigh groin area 1a and the crus area 2a are belt-like ones extending in the horizontal direction between the walking assist device main body 1 and the assist device main body lower portion 2, respectively. To the hook-and-loop fastener 1aa. In the embodiment shown in FIG. 1, two sets are each extended, and further extended on both sides, but may be on one side. In addition, the thigh groin portion 1a is attached to the thigh A, and the crus portion 2a is attached to the crus B.
[0016]
The thigh outer abutment plate 6 is the same as the thigh inner abutment plate 3 and is an elongated, substantially plate-like one that abuts the outer side of the thigh A. The thigh A of the human body. A slightly curved shape along the outer shape of the body is desirable, and is formed of a synthetic resin such as polyethylene having high durability and elastic restoring force, and the thigh extended from the walking aid main body 1 The attachment portion 1a is attached by attachment means 9 described later.
[0017]
Next, the crus outer abutment plate 7 is the same as the thigh outer abutment plate 6 and is an elongated, substantially plate-like one that abuts the outer side of the crus B. A shape along the outer shape of B is desirable, and is formed of a synthetic resin such as polyethylene having a strong durability and elastic restoring force. The part 2a is attached by attachment means 9 described later.
[0018]
Next, the knee joint outer rotating portion 8 is positioned outside the knee joint C, and rotates the lower end side of the thigh outer contact plate 6 and the upper end side of the crus outer contact plate 7. It is pivotally attached to the shaft so as to be rotatable.
[0019]
Then, the attachment means 9 places the thigh outer abutment plate 6 on the thigh groining portion 1a and the crus outer abutment plate 7 on the crus groining portion 2a at a predetermined attachment position. It is attached to be movable.
[0020]
That is, in the embodiment shown in FIG. 3, the attachment means 9 for movably attaching the attachment position is the vertical direction between the thigh outer abutment plate 6 and the crus outer abutment plate 7. A long hole 6a. With a width through which the thigh groin area 1a and the crus area 2a are inserted on both sides. 7a respectively, and the long holes 6a. 7a, the thigh groin area 1a and the crus groin area 2a are inserted from the back surface to the front surface, respectively, and the other long holes 6a. One that has a thigh Mekuchaku portion 1a and the lower thigh Mekuchaku portion 2a is respectively inserted from the front surface to the back surface to 7a, the left and right thigh outer abutment plate 6 or lower leg outer abutment plate 7 It is possible to move the mounting position by sliding it.
[0021]
The position fixing tool 9a is a planar member provided with hook-and-loop fasteners (not shown) on both sides, and is formed on both sides of the thigh outer abutment plate 6 and the crus outer abutment plate 7. Slot 6a. At the same time, the inner surface fastener of the folded back is inserted and fastened together, and a surface fastener is provided on the outer side of the position fixing tool 9a, and the outer surface fastener thigh garment portion 1a and the lower leg portion are provided. a predetermined position of Mekuchaku portion 2a in which are respectively fixed.
[0022]
The knee joint walking aid of the present invention is attached to the human knee first by contacting the thigh inner abutment plate 3 with the thigh A inside the foot and bending the knee joint C. The knee joint inner turning portion 5 is positioned so as to be aligned with the center position of the crus, and the crus inner contact plate 4 is brought into contact with the inner side of the crus B.
[0023]
Next, the thigh A is attached by the thigh attaching part 1a extended from the walking aid main body 1, and the thigh outer contact plate 6 is attached to the thigh A outside the knee. The knee joint outer rotating portion 8 is brought into contact with the center position of bending of the knee joint C, and the crus outer contact plate 7 is brought into contact with the crus B, respectively. A can be attached with a single touch with a hook-and-loop fastener 1aa provided at the tip.
[0024]
At this time, if the knee joint outer rotating portion 8 does not contact the center of bending of the knee joint C of the human body, the surface fastener of the position fixing tool 9a of the attachment means 9 is removed, and the thigh outer contact is made. The board 6 and the thigh heel part 1a, and the crus outer contact plate 7 and the crus part 2a are slid left and right. Even a thin person can move to a position that fits perfectly.
[0025]
Then, when the position is determined, the respective thigh groin area 1a and crus area 2a are adhered, and the walking aid main body is formed of a flexible material having a slight elasticity. 1. The assisting device main body lower part 2, the thigh groining part 1a, and the crus groining part 2a are securely attached to the knee joint C, the thigh A, and the crus B of the human body.
[0026]
The knee joint walking aid of the present invention includes a thigh inner abutment plate 3 and a knee joint inner abutment plate 4 via a knee joint inner rotation plate 5 on the inner and outer sides of the knee of the foot, and the thigh. The crus outer contact plate 7 is attached via the outer contact plate 6 and the knee joint outer rotation unit 8, and the knee joint C does not bend left and right, and walks straight in the forward direction. In particular, it can relieve pain in patients with a disease in the knee and ease walking.
[0027]
【The invention's effect】
The knee joint walking aid of the present invention has the above-described configuration, and the inner side of the thigh that abuts the inner side of the knee joint of the human body on the walking aid body having a slight elasticity and the lower part of the assisting tool body, respectively.
