Shoe 13 is preferably used in conjunction with an orthopedic foot splint, such as that described below. 6th
Figure 9A shows the leg splint. Briefly, the operating part of the foot splint comprises a heel plate rotation operation 10, a linkage device 11 and a central rotation device 12. A patient using a foot splint wears a particular pair of well-fitting shoes 13 as described above, which shoes 13 are provided with a heel plate 14. In order to attach the rotating device 10, the shoe 13 includes:
An upright plate 15 is provided extending upward from the inner edge of the heel plate 14. A rotating arm 16 is attached to each upright plate 15 by a rivet 18.
is installed. Each rivet 18 allows the pivot arm 16 to be pivoted about the rivet 18 as an axis. Each pivot arm 16 is provided with an elongated hole 20 extending vertically. Each pivot arm 16 can therefore slide perpendicularly along the surface of the upright plate 15 with respect to the pivot axis. In this embodiment, the distal end of each pivot arm 16 forms one wing of a hinge element 22 .
Each hinge element 22 has a horizontally extending pivot axis. The other wing of the hinge element 22 is bent at right angles and has an inwardly extending curved surface 24.

The link device 11 includes two pairs of links 28, each of which is a parallelogram component. Each pair of parallelogram links 28 is connected to each right angle curved surface 24 by a rivet 26. The central pivot device 12 has a central hinge element 30 .
The central hinge element 30 joins each pair of parallelogram links 28 to form a foot splint. Central hinge element 30 has a horizontally extending axis parallel to the axis of hinge element 22 . Each pair of parallelogram configuration links 2
8 is pivotally connected to each wing of the central hinge element 30 by a rivet 32.
Therefore, each pair of parallelogram-forming links 28
remain parallel during rotation.

FIG. 7 shows a device for adjusting the heel portion of the heel plate 14 at various angles. The device comprises a mounting plate 40 which is rigidly connected to the sole of the heel 110 of the shoe 13. Mounting plate 4
0 is adapted to slide over the angle adjustment plate 42 by means of an inwardly bent edge 44 that engages a notched edge 46 of the angle adjustment plate 42. Meanwhile, the angle adjustment plate 42 is coupled to the heel plate 14 by bolts 48. The bolt 48 passes through the heel plate 14 and reaches a screw hole 50 in the angle adjustment plate 42. A pin 52 hangs down from the angle adjustment plate 42, and a plurality of receiving holes 54 are provided in the heel plate 14 at approximately equal intervals.

The pin 52 has an angle adjustment plate 42 that is connected to the heel plate 1.
4 to prevent it from rotating around the bolt 48. The thickness of the angle adjustment plate 42 must be less than the depth from the bottom of the mounting plate 40 to the bottom of the inwardly bent edges 44. By doing this, when the angle adjustment plate 42 is pulled toward the heel plate 14 by the bolt 48, the angle adjustment plate 42 moves the mounting plate 40 toward the heel plate 1.
4 by frictional force. Therefore, when the bolt 48 is tightened, the heel portion of the mounting plate 40, the angle adjustment plate 42 and the heel plate 14
are tightly coupled into a set.

In use, the foot splint is treated as follows.
After establishing the patient's foot fixation angle, bolt 48 is loosened so that angle adjustment plate 42 can rotate around bolt 48. The pin 52 is then moved so that it is received in the hole 54 corresponding to the foot fixation angle. Next, the bolt 48 is tightened and the patient then puts on the shoe 13. The foot splint always holds the shoe 13 tilted at the selected angle. but,
The shoe 13 can be moved freely in other directions almost normally. As shown, the parallelogram link 28 can pivot about the rivets 26 and 32, allowing the patient to move the foot back and forth. Hinge element 22 and central hinge element 30 also allow the patient to move the foot up and down. Hinge element 22 and central hinge element 30 also allow the patient to move both legs simultaneously or separately. Furthermore,
The plate rotation device 10 also allows the patient to tilt his or her legs back and forth. The patient can therefore walk or climb almost normally. When the foot splint is used on an infant, it not only allows the infant to crawl almost normally, but also does not unduly impede the infant's efforts to learn to walk. The only thing that is hindered is the movement of the toes in and out.

FIG. 8 and FIG. 8A show the heel plate rotation device 10.
Here are some other examples. In this example, a device for raising and lowering the rotation axis of the rotation arm 82 is provided. Further, in this example, the rotation angle of the rotation arm 82 is limited, and the rotation arm 82 is connected to the heel plate 14.
A device is also provided for holding it in a perpendicular position. Only a portion of the heel plate 14 is shown in the figure. An upright plate 60 is coupled to the inner edge of the heel plate 14. Further opposing plate 6
6, and a pivot arm 82 with hinge element 22. The upright plate 60 has vertical slots 62 along it, and the inner surface of the upright plate 60 is provided with a number of horizontal grooves to create a serrated surface 64 in cross section. Facing the serrated surface 64 is disposed a serrated surface 68 of the opposing plate 66 which engages the surface 64. Opposite plate 66 is coupled to upright plate 60 by bolts 70. Bolt 70 passes through vertical slot 62 and locks into a threaded hole 72 in opposing plate 66. The opposing plate 66 further includes an arched guide groove 74 . A pivot post 78 having a wedge 76 and a threaded hole 80 is provided in the serrated surface 68 of the positioning plate 66 and the recess 75 on the opposite surface. Pivot post 78 extends beyond the outer circumferential surface of opposing plate 66 and projects therefrom a distance slightly greater than the thickness of pivot arm 82 . The pivot arm 82 has a hole 84 from which the pivot post 78 projects slightly. A rotating sleeve 86 extends from the outer surface of the rotating arm 82 so as to surround the rotating post 78. Also extending from the outer surface of pivot arm 82 is a projecting key 88 . A coil spring 90 is disposed around the rotation sleeve 86, and both ends of the coil spring 90 intersect and are locked to both ends of the protruding key 88. The threaded hole 80 passes through the hole 84.
The pivot arm 82 is coupled to the opposing plate 66 by a bolt 91 that is threaded into the pivot arm 82 .

In use, the plate rotation device 1 of the second example
0 operates as described below. The position of the right angle curved surface 24, i.e., the linkage device 11 relative to the heel plate 14, as is most comfortable or desirable for the patient.
The height is adjustable. This adjustment is accomplished by varying the height at which the opposing plate 66 is coupled to the upright plate 60. Thereby, the rotating arm 82 and the right-angled bending surface 24 can also be moved at the same time. To adjust the height of opposing plate 66, sufficient clearance is provided between cross-sectional serrated surfaces 64 and 68 so that opposing plate 66 is
Loosen bolt 70 until it can be slid along 0. Place the opposing plate 66 at the height desired by the patient and tighten the bolts 70. The height can be determined easily. By tightening bolt 70 , serrated surfaces 64 and 68 engage to secure opposing plate 66 to upright plate 60 . The link device 11 whose height is determined by the opposing plate 66 is also positioned at a constant height thereby.

The device for limiting the angle of rotation of the pivot arm 82 and for positioning the pivot arm 82 perpendicular to the heel plate 14 operates as follows. Pivoting arm 82 is coupled to opposing plate 66 by bolts 91 . After the key 88 enters the arched guide groove 74 and the wedge 76 is placed between the two crossed ends of the coil spring 90, the bolt 91 is tightened. Bolt 91 is tightened and engages the end of pivot post 78 . In this state, the rotating arm 82 is rotatable around the rotating column 78. However, since the key 88 is fitted into the arched guide groove 74, the rotation of the pivot arm is limited to the range in which the key 88 moves from one end of the arched guide groove 74 to the other end. Rotating arm 8
2 is moved away from the vertical position, the wedge 76 engages one end of the coil spring 90. At this time, the other end of the coil spring 90 is engaged with the key 88. This causes coil spring 90 to exert a force on pivot arm 82, pushing pivot arm 82 back to a vertical position where the ends of coil spring 90 no longer engage wedge 76.

An example of a heel plate rotation device 10 further comprising a device that allows the hinge element 22 to slide vertically relative to the upright plate 60 is shown in FIGS. 9 and 9A. Similar to the above-described example of the plate rotation device 10, this example also includes an upright plate 60 and an opposite plate 66 whose relative positions are adjustable in the same manner as described above. A coil spring 90 is attached to the rotation pillar 78 of the opposing plate 66, and the crossed ends of the coil spring 90 are locked to both ends of the wedge 76. Also,
A rotation arm 9 is provided on the rotation pillar 78 by a hole 94.
2 is rotatably mounted. Rotating arm 92
is provided with a projecting key 96 on one side, which key 96 extends into the arcuate guide groove 74 of the opposing plate 66. Two vertical grooves 98 are formed on the other side of the rotating arm 92 on both sides of the hole 94. A raised portion 100 provided on the sliding plate 102 so as to correspond to the vertical groove 98 fits into the vertical groove 98 . The sliding plate 102 has a vertical slot 104 from which a pivot post 78 projects slightly. Hinge element 22 is coupled to the lower end of sliding plate 102. bolt 9
1 passes through the hole 94 and the vertical slot 104 and is screwed into the screw hole 80 of the rotation post 78, and the rotation arm 9
2 and the sliding plate 102 are held on the opposing plate 66.

In use, this example operates similarly to the previous example. The opposing plate 66 is the upright plate 60
The rotation angle of the pivot arm 92 is limited and is biased to a vertical position. However, unlike the previous example,
The hinge element 22 is vertically slidable relative to the pivot arm 92 and thus relative to the upright plate 60. When a vertical force is applied to the hinge element 22, the sliding plate 102 moves into the vertical groove 9.
It moves freely along the pivot arm 92 guided by a raised portion 100 that slides within the pivot arm 92 . Vertical movement of sliding plate 102 is restricted at each end of vertical slot 104 which receives pivot post 78.

Effects of the Invention As described above, according to the present invention, regarding the correction of inversion of the forefoot, inversion of the foot, equinus, etc., the amount of correction can be achieved by simply adjusting the position of the toe plate relative to the heel plate. An orthopedic shoe device can be provided that is capable of holding a foot in a corrected position.
In particular, the shoe device has an inclined portion in which surfaces of the heel plate and the toe plate that face each other are inclined around a vertical axis with respect to an axis in the shoe width direction perpendicular to the longitudinal direction of the shoe. Therefore, by appropriately selecting the inclination angle of the inclined portion, it is possible to take a corrective posture suitable for the natural direction of joint flexion of the foot, and to perform correction effectively.

When the adjustment device is configured to enable the position adjustment by coupling the toe plate to the heel plate so as to be rotatable about an axis substantially perpendicular to the slope, the front part of the foot is It is particularly advantageous for correcting a patient's foot in adduction and abduction about the longitudinal axis.

In addition, when the adjustment device is configured to enable position adjustment by coupling the toe plate to the heel plate so as to be rotatable around an axis along the inclined portion, It is particularly advantageous for correcting feet with ivy forefoot.

Furthermore, when the adjustment device is provided with a universal joint, and the toe plate is coupled to the heel plate so as to be rotatable in any direction so that the position can be adjusted, the front part of the patient's foot can be adjusted. It has the advantage that it can be widely applied to the correction of various symptoms such as adduction, abduction, inversion, eversion, and equinus of the foot.
