Abstract
An orthopedic insole consists of a hollow foothold having flexible walls and containing granular filling. The upper surface of the orthopedic insole is typically molded to conform the anatomical features of a regular human foot. The granular filling contained in the lumen of the foothold and a rigid segment of its bottom wall provide for adapting the curvature angles of the top surface of the foothold to a specific pattern of the foot of a user. A user can typically make a selection from a variety of ready-made insoles having standard sizes which suit his needs. The adaptable orthopedic insoles of the invention are accommodated to common shoes and sandals, boots that are suitable for heavy work, walking, running, and or fashionable or mode shoes.
Description
- The present invention relates in general to orthopedic and in particular to orthopedic insoles accommodated to a variety of footwear and adaptable to the foot of a user.
- A significant portion of the population suffers from irregular or abnormal foot pattern, which are typically associated with physical discomfort induced by prolonged standing, walking and or running. Orthopedic shoes may in such cases be offered as a relief from the physical discomfort. Orthopedic insoles tailored to a user foot and specific footwear normally provide for converting common footwear into orthopedic. However an expert is typically involved with the manufacturing of orthopedic insoles. Furthermore the adaptation of orthopedic insoles to the user's feet is often associated with revisiting the expert for the accommodation and fine-tuning.
- The characteristics of healthy and normal feet are prone to change by aging, which in turn might cause such physical discomfort as well. Therefore ready made orthopedic insoles, which are adaptable to the user's feet and are conformal with a variety of footwear are called for.
-
FIG. 1 is an isometric view of an orthopedic insole according to a preferred embodiment of the present invention; -
FIG. 2 is an isometric view of the orthopedic insole shown inFIG. 1 in which its bottom face is shown; -
FIG. 3 is transverse sectional view of a foothold of the orthopedic insole shown inFIG. 1 ; -
FIG. 4 is an isometric view of an orthopedic insole according to another embodiment of the present invention; -
FIG. 5 is a flow chart describing a method for manufacturing an orthopedic insole in accordance with a preferred embodiment of the present invention; - In accordance with the present invention an adaptable orthopedic insole is provided. The orthopedic insole of the invention consists of a hollow foothold having flexible walls and containing granular filling. The upper surface of an orthopedic insole of the invention is typically molded to conform the anatomical features of a regular human foot. The granular filling contained in the lumen of the foothold and a rigid segment of its bottom wall provide for adapting the curvature angles of the top surface of the foothold to a specific pattern of the foot of a user. A user can typically make a selection from a variety of ready-made insoles having standard sizes which suit his needs. The adaptable orthopedic insoles of the invention are accommodated to common shoes and sandals, boots that are suitable for heavy work, walking, running, and or fashionable or mode shoes.
- Reference is now made to
FIGS. 1-3 in which two isometric views of an adaptable orthopedic insole and a sectional view of its foothold according to a preferred embodiment of the present invention are respectively shown. Adaptableorthopedic insole 10 hasinner face 12 andouter end 14,tarsal support 16, an optionalmetatarsal support 18 sloping upwards andmedial arc support 20. Medial arc support 20 slopes longitudinally towardsouter end 14. Elongatedrigid plate 40 is embedded inbottom face 42 of adaptableorthopedic insole 44. The frontal and rear segments ofbottom face 42 are uncovered byrigid plate 40 permitting the deformation of the corresponding portions ofadaptable insole 44 concomitantly with respective rotational movements of the tarsal and metatarsal portions of a user. - In
FIG. 3 a sectional view along line AA of a foothold of the adaptable orthopedic insole shown inFIG. 2 is shown. Upper face 60 of the foothold 62 of the orthopedic insole downwardly slopes frominner wall 64 towardsouter wall 66. Rigid plate 68 is embedded in the outside face of bottom wall 70 of foothold 62. The foothold of adaptable orthopedic insoles of the invention is made of flexible materials. Footholds are manufactured in standard sizes and shapes such as by blow molding utilizing PVC, polyethylene, or other plastic resins. Rigid plates are manufactured also in standard sizes and are typically made of metal such as aluminum. The rigid plates are typically attached into conformal recesses located at the external surface of the bottom face of the foothold. The footholds are typically further covered such as by fabric, leather, neoprene, and nylon or similar plastic resins. The lumen of a foothold of adaptable orthopedic insole of the invention is filled with granular material such as polyethylene through a dedicated filling aperture that is typically located at a sidewall. The volume of the filling is typically lower by a few percents from the capacity of the hollow foothold. Attaching such as by gluing conformal cover to the filling aperture then closes the filling within the lumen of an insole. Air vents whose sizes are smaller than the sizes of the grains of the filling, located across sidewalls such asinner wall 64 andouter end 66 permit slow equalizing of internal air pressure with the atmosphere when the insoles are pressed by the weight of a user, thereby providing a cushioning effect. - The adaptable orthopedic insoles of the invention are accommodated to any shoe or sandal that surrounds a significant portion of the foot of a user. However in cases in which footwear that are open near the fingers and or the ankle, a substantially shallow recess located at the inner sole of the footwear and conformal with the bottom surface of the insole has to be first provided. Such a recess provides for keeping the adaptable orthopedic insole in place while being in use.
- In another embodiment of the invention the insole is short, covering only a part of the footwear as shown in
FIG. 4 to which reference is now made. Elongatedrigid plate 74 is embedded in the bottom face of the adaptable orthopedic insole. With respect to orthopedic insole shown inFIG. 2 the front segment of the orthopedic insole has been removed, in this case bytransverse cut 80.Rear segment 82 of the bottom face of the adaptable orthopedic insole is not covered byrigid plate 74, as in the other embodiments, permitting a deformation of the corresponding portions of adaptable insole concomitantly with the respective rotational movement of the tarsal and metatarsal portion of a wearer. - A flow chart describing a method for manufacturing an orthopedic insole in accordance with a preferred embodiment of the present invention is described in
FIG. 5 to which reference is now made. At step 90 a mold in standard shape for an orthopedic insole is provided. At step 92 a moldable material such as PVC, polyethylene, or any other suitable plastic resin is injected to the mold. At step 94 a process of blow molding (BM) is provided, in which the injected plastic resin is blown. Atstep 96 the hollow insole that is formed in the molding process is released from the mold. Then, atstep 98 the hollow insole is filled with granular material and instep 99 the area of the injection is sealed. Atstep 100 the foothold is covered such as by fabric, leather, neoprene, nylon or similar plastic resins. At step 102 a rigid plate is attached in bottom face of orthopedic insole. - It should be noted that some steps of the above described process can be combined, executed repeatedly, omitted and/or rearranged.
