[0002]
[Prior art]
Conventionally, lower limb orthoses worn on the legs have been used to assist the walking function or to promote functional recovery for patients who have difficulty walking due to leg paralysis or dysfunction of the hip joint. ing. As such a lower limb orthosis, a sole plate material 1 as shown in FIG. 5 with side plate portions 1a projecting left and right is press-molded to form a sole plate 2 in which a supporting side plate 2a is formed in a hook shape as shown in FIG. In some cases, a shoe body 3 for covering the foot is attached on the upper side, and a shoe sole body 4 is provided on the lower side of the sole plate 2. As shown in FIG. 7, such a conventional lower limb orthosis is such that the support side plate 2 a is raised upward at the position directly below the left and right hip joints of the shoe body 3, and the upper end of the support side plate 2 a is raised. After the formed joint plate portion 2b is formed so as to coincide with the rotational axis position of the joint, a coupling member 5b fixed to the lower ends of a pair of support columns 5 provided at the upper portion with a lower limb cuff 5a coupled to the lower limb; The joint plate portion 2b is coupled by a connecting pin 6 so as to be swingable in the front-rear direction.
[0003]
Such a lower limb orthosis is manufactured according to the size of the wearer's foot, and the sole plate used for this is necessary to support the weight and to withstand the impact during walking. Therefore, a variety of standard materials with various dimensions including the position of the joint plate and the overall dimensions are formed in advance using a tough material. It was manufactured by selecting a suitable size and pressing it according to the wearer.
[0004]
However, in order to bend the left and right side plates to suit the wearer by selecting the appropriate size from a large number of materials prepared according to the standard, various materials are available in stock. There are uneconomicalities that must be overcome. In addition, if there is a deviation in the axial position of the left and right joint plate parts, there is a risk that the device will be subjected to abnormal stress and impair durability, so it is necessary to increase the accuracy of bending with a press. There is a disadvantage that is required. And, if processing with an emphasis on durability, the gap between the shoe body and the support side plate is large and it tends to become a rugged form, and the left and right support side plates do not have the same way of bending, so it is possible to create an unsightly appliance. There was also a problem of end up.

An object of the present invention is to provide a lower limb provided with a shoe body on the upper side of a sole plate in which a pair of supporting side plates provided with a joint plate portion supporting a lower limb support so as to be swingable at the tip position are provided upward on the left and right. In the brace, the support plate portion from the lower end of the pair of support side plates to the lower end of the joint plate portion has a front side edge interval larger than a rear side edge interval, and on the left and right side surfaces of the shoe body. The joint plate portion can be achieved by a walking lower limb orthosis that is formed so as to coincide with a plane perpendicular to the rotation axis of the hip joint.
[0007]
And as a sole plate used in such a lower limb orthosis for walking, a pair of side plate portions extending in a diagonally backward direction from the left and right end positions of the site directly below the hip joint in the sole plate material are bent upward to support side plates. Those formed by forming are particularly preferably used.
[0008]
Furthermore, the lower limb orthosis for walking according to the present invention described above includes a pair of side plate portions for forming a support side plate in which a joint plate portion supporting the lower limb struts is extended at the tip of the support plate portion. Using the sole plate material that extends diagonally backward from the left and right end positions , the side plate portion is bent upward at the front spreading line position along the left and right outside of the position directly below the ankle joint of the shoe fixed to the upper side of the sole plate material. And forming the sole plate including the support side plate shaped in parallel so that a pair of the joint plate portions coincides with a plane perpendicular to the rotation axis of the heel joint. A pair of plate portions is provided with a pin hole coaxial with the pivot shaft of the heel joint, and then the support column is swingably coupled to the joint plate portion by a coupling pin fitted into the pin hole. It can be manufactured by providing the shoe body on the upper side of the sole plate. That.
