MUSCULAR STRENGTHENING APPARATUS FOR THERAPEUTIC ORTHOPAEDICS
The invention concerns a muscular strengthening apparatus for therapeutic orthopaedics in aid of persons having deflective foot construction such as flat feet, claw feet and similar malformed fee .
The purpose of the muscular strengthening apparatus for therapeutic orthopaedics is to enable persons with deflective foot construction to train their toe, foot, calf and lower leg muscles relating to the deflections of the foot, in a simple way and when necessary in order to support the separate bones in their feet and lower leg, to correct the posture of and the leaning on their feet and to improve their way of motion. By doing so, their foot construction will be corrected without using exterior and permanent devices like prostheses and/or supporting soles.
Today's state of the art provides almost exclusively exterior support and/or correction of the form of feet and/or sole by using supporting soles or specialized shoes which remove the effects of the main problem but don't solve its cause in an adequate way. Besides that, existing training devices for feet are often complex in their design and/or production procedure, as shown in PN: US4186920 A 19800205; US3612519 A
19711012; EP0155415 A 19850925 and US3702188 A 19751107.
Others are insufficient, as shown in PN: DE19856995 A
19990602; US5980433 A 19991109 and EP0453095 A 19911023.
Still others are difficult to use and/or awkward, as shown in' PN: US2760774 A 19560828; US4483532 A 19841120.
The muscular strengthening apparatus for therapeutic orthopaedics shown in figure 1 consists of a base plate with concave friction surface (1), a bearing (2), a friction disk with flat friction surface (3) and a heel support (4) . The user, sitting on a chair or standing up straight, places the apparatus on the floor in front of him, with or without a
carpet underneath and places the heel of his bare foot (5) upon the heel support (4) . After stretching his foot (5) outward (abduction) the user bends his sole and toes in a way that his toe tips press on top of the friction disk with flat friction surface (3) . Thus gripping the friction disk with flat friction surface (3) , the user turns it inward (adduction) with his foot (5) . The user repeats this process a several times. The resistance experienced by the user defines the level of difficulty and the effectiveness of the practice and can be easily adjusted by turning the base plate with concave friction surface (1) in relation to the heel support (4) which is kept in position by clenching on the edge of the base plate with concave friction surface (1) . The heel support (4) screws into the base plate with concave friction surface (1) so that it can be adjusted deeper or higher in the base plate with concave friction surface (1). By screwing the heel support (4) deeper into the base plate with concave friction surface (1) the heel support (4) presses harder onto the bearing(2), consequently the bearing(2) presses harder onto the friction disk with flat friction surface (3) which in its turn presses harder onto the base plate with concave friction surface (1). By doing this the friction surface of the base plate with concave friction surface (1) deforms and the contact area and pressure between the base plate with concave friction surface (1) and the friction disk with flat friction surface (3) increases. This results in a greater friction between the base plate with concave friction surface (1) and the friction disk with flat friction surface (3).
Today's devices meant to improve the strength of the foot and ankle muscles don't succeed in correcting malformed feet. This is mainly due to the complex design, the set-up of the apparatus as well as the complexity of its application. Also because of incorrect exercising or concentrating the training on one specific or a wrong muscle, the efficiency of these devices often leaves much to be desired. On the other hand

the use of prostheses, supporting soles or other adapted shoes rather slackens than reinforces the muscles related to the deflection of the feet.
With the muscular strengthening apparatus for therapeutic orthopaedics the solution to all these problems lies in the combination of the following features: simplicity of use, simplicity of construction, simplicity of production process and its ambulant applicability.
The simplicity of use, construction and production procedure is obtained by building up the muscular strengthening apparatus for therapeutic orthopaedics in only four components and in such a way that it still remains efficient.
Figure 1 and 2 shows the construction of the muscular strengthening apparatus for therapeutic orthopaedics. The muscular strengthening apparatus for therapeutic orthopaedy shown in figures 1 and 2 consists of a base plate with concave friction surface (1), a bearing(2), a friction disk with flat friction surface (3) and a heel support (4). The heel support (4) screws into the base plate with concave friction surface (1) so that it can be adjusted deeper or higher in the base plate with concave friction surface (1). By screwing the heel support (4) deeper into the base plate with concave friction surface (1) the heel support (4) presses harder on the bearing(2) , consequently the bearing(2) presses harder on the friction disk with flat friction surface (3) which in its turn presses harder on the base plate with concave friction surface (1). By doing this the friction surface of the base plate with concave friction surface (1) deforms and the contact area and pressure between the base plate with concave friction surface (1) and the friction disk with flat friction surface (3) increases. This results in a greater friction between the base plate with concave friction surface (1) and the friction disk with flat friction surface (3) .
In this described but not limiting application of the muscular strengthening apparatus for therapeutic orthopaedics for flat feet, shown in figures 3,4,5 and 6, the user places the apparatus in front of him with the base plate with concave friction surface (1) on the floor, and then places the heel of his bare foot (5) upon the heel support (4), which is turned in his direction as displayed in figure 3. After turning his stretched foot (5) outward as shown in figure 4, the user bends his sole and toes in such a way that his toe tips press on top of the friction disk with flat friction surface (3) as shown in figure 5.
Thus gripping the friction disk with flat friction surface (3) with the foot, he turns the friction disk with flat friction surface (3) inward as illustrated in figure 6. The user repeats this procedure several times. The resistance experienced by the user defines the level of difficulty and the effectivity of the practice. This resistance can be easily adjusted by turning the base plate with concave friction surface (1) in relation to the heel support (4) which is kept in position by clenching on the edge of the base plate with concave friction surfaced).
The muscular strengthening apparatus for therapeutic orthopaedics can be used both on the left foot and the right foot as well as for both feet in a left hand or in a right hand load, whether or not alternating, depending on which muscles they want to have the desired effect. (abduction and adduction)
The muscular strengthening apparatus for therapeutic orthopaedics is applicable for flat feet, for claw feet as well as for otherwise malformed feet, both ambulant and on a permanent location, for correction, rehabilitation, for muscular reinforcement as part of a private initiative, for medical purposes as well as for sport and fitness training. No domain of application of the muscular strengthening

- 5 - apparatus for therapeutic orthopaedics causes any configuration related preference.
The muscular strengthening apparatus for therapeutic orthopaedy in the described configuration consists of only four components which, contrary to existing devices, increases ease and simplicity of use, construction and production process in a significant way.
The construction is so compact that transport of the muscular strengthening apparatus for therapeutic orthopaedy is very easy, enabling the user or the therapist to take it with him on his home visit.
