EASILY REMOVABLE ORTHOPEDIC SI IOE PLATFORM BACKGROUND OF THE INVENTION Patients suffering various degrees of paralysis in their lower limbs exhibit various foot troubles such as ankle weakness, drop foot, fallen arches and the like which result in inward or outward rolling of the foot or inability to raise the foot to horizontal level when walking. Various means have been provided in the past for corthe sole of a foot is formed of heavy leather, sheet plasrecting this problem generally involving the incorporation of a rigid supporting member within a shoe or similar device into which the foot of the patient is placed and which incorporates a rigid member positioned to support the ankle, or a lifting means designed to exert pull on the front of the foot to keep it in elevated position when walking. Such devices are shown in U.S. Pat. Nos. 1,350,944, 3,308,829, 3,527,209 and the like. Such devices have certain disadvantages in addition to the expense of designing special shoes for the purpose, such disadvantages being discomfort during use, difficulty in putting on and off by a partially paralyzed person, excessive weight and similar factors.
SUMMARY OF THE INVENTION It is the purpose of the present invention to provide a platform into which can be positioned an ordinary shoe worn by a patient, which is relatively light, flexible and can easily be put on and removed with one hand by a patient or by anyone else. This platform incorporates rigid ankle supports to prevent rolling either inward or outward or both and can at the same time prevent foot drop by restricting downward movement of the foot or by providing an upward pull on the front portion of the foot. Easy positioning and removal is provided by means of flexible heel supports and cooperating fasteners such as the hook and loop fabric type positioned both on the inner portion of the heel support and the shoe. Adjustable bracing means are provided so that the support may be used with various sized shoes.

Referring now to the drawings, as shown in FIGS. 1, 2 and 3 a platform 10 shaped generally to conform to tic or similar sheet material, preferably flexible but with sufficient rigidity to be shape retaining and self supporting. A toe enclosing member 11 is attached to the front edge of 10 and so shaped and dimensioned as to enclose the toe of a shoe to be positioned on the platform. A vertical ankle supporting member 12 is attached to the platform by means of plate 13 affixed by rivets or bolts as shown. Members 12 and 13 may be formed of a single piece of metal or rigid plastic and formed at right angles to provide the base portion 13 and vertical member 12. Base member 13 may be laterally adjustable by using bolts to fasten it to the platform through slots to permit a certain degree of adjustment to permit close engagement of 12 with the ankle of a user.
As shown in FIG. 4, member 12 may be padded by applying a cushioning layer 15 of sponge rubber or plastic, or other padding material covered with a layer of flexible vinyl plastic or cloth 16.
As shown in FIGS. 1 and 2, heel supporting member 14 formed of flexible and resilient sheet material such as leather, plastic or cloth is attached to the rear portion of the platform and shaped to engage the heel portion of a shoe. Interiorly of member 14 is mounted one component of a two part hook and loop fabric fastening unit known as Velcro and on the shoe which is positioned on the platform a corresponding layer of the other component of this fastening means is provided. This is illustrated on the folded over portion 14a of FIG. 2 which shows the Velcro areas 17 on 14 and 17a on the heel area of the shoe 18, a similar area is provided on the opposite interior portion of 14 and the opposite heel portion of the shoe. By this means one using the platform need only fold back heel portion 14, insert the foot with shoe on the platform with the toe of the shoe inserted into toe member 11 and then press heel member 14 with its fastening members against corresponding areas on the heel of the shoe. This can be easily done with one hand. Member 19 is provided to facilitate pulling the platform in position or for detaching member 14 before removing the shoe.
Velcro is the registered trademark of the Velcro corporation, T.M. 661700, for goods described as A synthetic material sold in ribbon, sheet or piece goods form, said material having complemental parts which adhere to each other when pressed together and adapted for use as a closure fastener or button for closing garments, curtains or the like. It is formed of Nylon or other plastic elements in the shape of hooks on one component and loops on the other as shown in U.S. Pat. Nos. 2,717,437, 3,147,528, and others. The segments of this material may be attached by sewing or adhesives. The degree of attachment will depend on the area of Velcro provided. In general a contact area of one or two square inches is adequate. Other types of fasteners may also be used such as snap fasteners, clips,
or the like.
sponding fastening areas on the shoe, as shown at 26 and 27. If desired, the platform member may be preformed with a slight upward curvature at the toe to ensure engagement with the ground while walking to counteract any tendency for foot drop.
A further modification of the invention is shown in FIGS. 7 and 8 in which elongated ankle supports are provided to extend beyond the ankle in a manner to provide support above the ankle. A disassembled view is shown in FIG. 7 with platform having toe engaging portion 31 and flexible heel portion 32 attached thereto. A rigid U-shaped ankle supporting member 33 is affixed to the platform at the area corresponding to the arch of the foot with'its vertical arms 34 and 35 extending upwardly at right angles to the base 36 and being long enough to extend above the ankles of a wearer as shown in FIG. 8. These arms are covered with leather or other suitable padding material. The shoe 37 worn by the patient is provided with Velcro" or the like fastening areas 38,380, 39, and 39a positioned adapted to engage corresponding areas on the heel and ankle support means respectively as shown at 40 and 40a, and 41 and 41a. In order to give additional support for the elongated ankle braces, fastening means to be applied above the ankles is provided. This is in the form of a strap member 42 provided with a pair of side loops 43 and 44, and having Velcro fastening members 45, 45a attached at the ends thereof, one component at the inside surface and the other at the outside surface. Heel member 32 is provided with a loop member 46 and ankle brace members are provided with Velcro fastening areas 47 and 47a at the outside surface thereof above the ankle area, as shown. Members 34 and 35 are provided with flaps. 48 and 49 on the outer surface of which near the end, are provided Velcro areas 50 and 50a complementary to areas 47 and 47 1, respectively.
When the patient wearing the shoe wishes to attach the platform device he inserts the toe of the shoe into member 31, affixes heel member 32, attaching areas 40 and 40a to areas 38 and 38a and areas 41 and 41a to areas 39 and 39a. Strap member 42 is then positioned through loop 46 and around the ankle and ankle supports 34 and 35 passing through loops 43 and 44. Flaps 48 and 49 with the Velcro areas 50 and 50a engaging complimentary areas 47 and 47a are then positioned over loops 43 and 44. The ends of the strap are then firmly fastened at the front of the ankle by engaging Velcro areas 45 and 45a.
The finally assembled unit is shown in F IG. 8. On disassembly, the shoe is easily removed by detaching the ends of the straps and flaps 48 and 49-. Heel member 32 is then pulled from the shoe and the user can easily remove the shoe while on his foot from the device.
