Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to the field of orthopedic devices for insertion into one&#39;s shoes and more particularly to a platform for accurately placing and holding orthopedic aids. 
       BACKGROUND OF THE INVENTION 
       [0002]    Many traumatic conditions of the foot are caused by the misalignment of the joints in the foot. Such conditions can be hereditary or can be caused by an accident or repetitive stress. No matter the cause, people who suffer from such ailments are often in pain during normal activities such as walking and exercising. In some cases, the condition is so bad; it causes excruciating pain to the extent a person cannot walk without an orthopedic aid. 
         [0003]    Often, the solution to the problem is to provide a contoured surface under the patient&#39;s foot, thereby redistributing the force of the wearer&#39;s weight over different areas of the foot or raising a toe to its normal posture, etc. Prior solutions to this problem included providing a shoe with an integrated, prescription form, compensation for the malformed foot. Unfortunately, such a solution is not cost-effective because the prescribed form must be present in all shoes used by the patient. Furthermore, it is often difficult to form the precise lifts in the precise location as needed. Once the shoe is made, if it doesn&#39;t fix the problem, there is no way to adjust lifts within the shoe. 
         [0004]    A solution to this problem is proposed in U.S. Pat. No. 6,205,685 to Kellerman and is hereby incorporated by reference. This patent has a shoe insert that has an adhesive on its surface where it contacts the shoe&#39;s inner sole. The opposite side is covered with loop material (e.g., Velcro®). Once installed on the inner sole, one or more pads having hook material on their bottom surface are positioned on the loop material. The solution presented in this patent has several problems. First, it is extremely difficult to accurately position the pads using the hook and loop material. Second, the described device is permanently installed into the user&#39;s shoe, requiring a device for each shoe the user owns. Third, hook and loop material and the adhesive bottom surface are generally thick, causing crowding of the foot in many shoes. Finally, for those with severe problems where they cannot walk without the prescribed device, it is extremely difficult to try on new shoes that are absent the prescribed platform. 
         [0005]    Another solution to this problem is proposed in U.S. Pat. No. 4,316,333 to Rothschild. This too has a pressure-sensitive element with hook or loop material and engaging elements with hook or loop materials that are positioned on the pressure-sensitive element within the shoe. This solution has several problems similar to the prior patent. First, it is extremely difficult to accurately position the pads using the hook and loop material. Second, the described device is permanently installed into the user&#39;s shoe, requiring a device for each shoe the user owns. Third, hook and loop material and the adhesive bottom surface are generally thick, causing crowding of the foot in many shoes. Finally, for those with severe problems where they cannot walk without the prescribed device, it is extremely difficult to try on new shoes that are absent the prescribed platform. 
         [0006]    Another solution is proposed in U.S. Pat. No. 2,573,363 to Ruddick. This patent proposes a band that wraps around the user&#39;s foot and has toe straps that go between the user&#39;s toes, thereby holding the band in place within the user&#39;s shoe. The engaging elements are directly attached to the band. This solution addresses several of the problems such as being worn on the foot instead of installed in the shoe, therefore, one device can be used with multiple shoes. Still, this patent is not a complete solution. Unfortunately, this device is made with pads in specific locations, making adjustment impossible. 
         [0007]    What is needed is an adjustable orthopedic solution that provides a platform for securely and accurately affixing one or more orthopedic elements in position beneath the effected bone. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION 
       [0028]    Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures. 
         [0029]    Referring to  FIG. 1A , a side schematic view of a system of a first embodiment of the present invention will be described. Often, to combat orthopedic problems, a doctor recommends or prescribes a remedy that includes placing pads or raised areas beneath affected areas of the foot. Past solutions included prescription shoes with such raised areas integrated into the curvature of the inner sole of the shoe. Unfortunately, such a solution requires the prescription to be replicated across all shoes the wearer owns. Furthermore, once manufactured, it is difficult to make any fine adjustments. 
         [0030]    The solution of the present invention includes a platform  10  and one or more raised pads  30  that stick to the platform  10  and are easily adjusted by swapping with other raised pads  30  or by manually repositioning the raised pads along the X and Y axis upon the platform  10 . In the preferred embodiment, the raised pads  30  are held to the platform  10  by magnetic force, either having a magnet integrated into the bottom of the raised pads  30  and using a ferromagnetic material such as iron or steel for the platform  10 ; having a magnetic material integrated into the bottom of the raised pads  30  and using a ferromagnetic material for the platform  10 ; or using a magnetic material for both the bottom of the raised pads  30  and the platform  10 . In some embodiments, the magnet is a solid magnet. In other embodiments, the magnet is flexible, made from powdered iron as known in the industry. In some embodiments, the platform  10  is covered on the bottom by a plastic coating or plastic sheet to prevent tearing and wear on the shoe. In some embodiments, the platform  10  is coated with a sticky or tacky surface to reduce movement within the wearer&#39;s shoe. 
         [0031]    In the preferred embodiment, the platform  10  is held within an anchor strap  16  of a holder that is worn like a sock around the wearer&#39;s foot  22 . The holder includes a stretch strap or cloth elastic band  12  that is worn around the wearer&#39;s foot between the toes and the ankle. In the preferred embodiment, one or more toe straps  14  connect between top forward edges of the strap  12 , pass between the wearer&#39;s toes and connect to the bottom forward edges of the strap  12 . The toe straps  14  keep the holder from rotating around the wearer&#39;s foot  22  and keep it from sliding back within the wearer&#39;s shoe  20  while walking. The platform  10  slides into the holding strap  16  and is kept from moving forward by making notches  11  as shown in  FIGS. 1B and 2 . The platform  10  is sandwiched between the bottom of the wearer&#39;s foot  22  and the sole  21  of the shoe  20 . Being that the holding strap  12  secures the holder to the wearer&#39;s foot  22 , the wearer can change between shoes, try on new shoes, etc. without needing additional devices. 
         [0032]    Referring to  FIG. 1B , a top schematic view of a system of the first embodiment of the present invention will be described. The platform  10  is held within an anchor strap  16  of a holder that is worn like a sock around the wearer&#39;s foot. The holder includes a stretch strap  12  that is worn around the wearer&#39;s foot at a location between the toes and the ankle. In the preferred embodiment, one or more toe straps  14  connect between top forward edges of the strap  12 , pass between the wearer&#39;s toes and connect to the bottom forward edges of the strap  12 . The toe straps  14  keep the holder from rotating around the wearer&#39;s foot  22  and keep it from sliding back within the wearer&#39;s shoe  20  while walking. The platform  10  slides into the holding strap  16  and is kept from moving forward by making the holding strap  16  smaller than the larger width of the platform  10  at a notch or inflection point  11 . Being that the holding strap  12  secures the holder to the wearer&#39;s foot  22 , the wearer can change between shoes, try on new shoes, etc. without needing additional devices. One or more raised pads  30  are held to the platform  10  and are easily adjusted by swapping with other raised pads  30  or by manually repositioning the raised pads along the X and Y axis upon the platform  10 . In the preferred embodiment, the raised pads  30  are held to the platform  10  by magnetic force, either having a magnet integrated into the bottom of the raised pads  30  and using a ferromagnetic material for the platform  10 ; having a magnetic material integrated into the bottom of the raised pads  30  and using a ferromagnetic material for the platform  10 ; or using a magnetic material for both the bottom of the raised pads  30  and the platform  10 . 
         [0033]    Referring to  FIG. 2 , a plan view of the magnetic platform  10   a  of the first embodiment of the present invention will be described. In this embodiment, the magnetic platform  10   a  is sized to accommodate both metatarsal pads and toe crest (or buttress) pads. The magnetic platform  10   a  has a narrow area (the area forward of the notch  11 ) that fits within the holding strap  16  (see  FIG. 1 ) while the wider area (the area rear of the notch  11 ) keeps the magnetic platform  10   a  from pushing forward as the wearer walks. In some embodiments, a cut line  31  is provided to guide the user in cutting unneeded sections of the magnetic platform  10   a . If the user needs only a toe crest pad, the back area of the magnetic platform  10   a  is cut along the cut line  31  and removed. 
         [0034]    Referring to  FIG. 2A , a plan view of the magnetic platform  100  of an alternate design of the first embodiment of the present invention will be described. In this embodiment, the magnetic platform  100  is sized to accommodate both metatarsal pads and toe crest (or buttress) pads. The magnetic platform  100  has a narrow area (the area between the notches  11 ) that fits within the holding strap  16  which keeps the magnetic platform  100  from pushing forward, pushing rearward or twisting as the wearer walks. In some embodiments, a cut line  31  is provided to guide the user in cutting unneeded sections of the magnetic platform  100 . If the user needs only a toe crest pad, the back area of the magnetic platform  100  is cut along the cut line  31  and removed. 
         [0035]    Referring to  FIG. 3 , a plan view of a magnetic platform  10   b  of the second embodiment of the present invention will be described. In this embodiment, the magnetic platform  10   b  is sized to accommodate only toe crest (or buttress) pads. The magnetic platform  10   b  has a narrow area (the area forward of the notch  11 ) that fits within the holding strap  16  (see  FIG. 1 ) while the wider area (the area rear of the notch  11 ) keeps the magnetic platform  10   b  from pushing forward as the wearer walks. 
         [0036]    Referring to  FIG. 4 , a plan view of the magnetic platform  10   c  of the third embodiment of the present invention will be described. In this embodiment, the magnetic platform  10   c  is sized to fit snuggly within a predetermined shoe such as a insole would fit. It is anticipated that several different sizes of the magnetic platform  10   c  will be provided for different shoe sizes or a larger magnetic platform  10   c  will be provided with cut lines provided to guide the user or doctor in trimming the magnetic platform  10   c  to the desired shoe size. The magnetic platform  10   c  is designed to accommodate any combination of metatarsal pads, toe crest (or buttress) pads and/or arch support pads. 
         [0037]      FIGS. 5-10  show different combinations of metatarsal pads  30 / 32 / 34  and toe crest (or buttress) pads  40 / 42 / 44 , each pad sized and shaped to remedy a particular bone problem of the user&#39;s foot. It is anticipated that many different metatarsal pads and toe crest (or buttress) pads will be provided with varying degrees of height and contour and the orthopedic doctor will determine the right pad for the particular ailment. The magnetic platform  10  provides for the ability to uniquely and adjustably position the selected pad(s) at any location to remedy the unique ailment of the individual patients. For reference, the metatarsal bones and phalanges are numbered, the bones of the big toe  80  being numbered  1  and the bones of the little toe  82  being numbered  5 . 
         [0038]    Referring to  FIGS. 5 and 6 , a top and side plan view of the first and second embodiments of the present invention will be described. The magnetic platform  10  is installed in the holding strap  16  and held to the wearer&#39;s foot  22  by the elastic cloth band  12  (shown in  FIG. 6 ). The toe straps  14  limit the amount of rotation and front/back movement of the elastic cloth band, thereby holding the magnetic platform  10  in a relatively stable position with respect to the wearer&#39;s foot  22 . In the example shown in  FIG. 5 , a metatarsal pad  40  is in place on the magnetic platform  10  to compensate for a problem with the fourth metatarsal bone and a toe crest pad  30  is in place on the magnetic platform  10  to compensate for a problem with the second phalange bone. 
         [0039]    Referring to  FIGS. 7 and 8 , another top and side plan view of the first and second embodiments of the present invention will be described. As previously described, the magnetic platform  10  is installed in the holding strap  16  and held to the wearer&#39;s foot  22  by the elastic cloth band  12  (shown in  FIG. 8 ). The toe straps  14  limit the amount of rotation and front/back movement of the elastic cloth band, thereby holding the magnetic platform  10  in a relatively stable position with respect to the wearer&#39;s foot  22 . In the example shown in  FIGS. 7 and 8 , a metatarsal pad  42  is in place on the magnetic platform  10  to compensate for a problem with the third metatarsal bone and a toe crest pad  32  is in place on the magnetic platform  10  to compensate for a problem with the third phalange bone. 
         [0040]    Referring to  FIGS. 9 and 10 , another top and side plan view of the first and second embodiments of the present invention will be described. As previously described, the magnetic platform  10  is installed in the holding strap  16  and held to the wearer&#39;s foot  22  by the elastic cloth band  12  (shown in  FIG. 10 ). The toe straps  14  limit the amount of rotation and front/back movement of the elastic cloth band, thereby holding the magnetic platform  10  in a relatively stable position with respect to the wearer&#39;s foot  22 . In the example shown in  FIGS. 9 and 10 , a metatarsal pad  44  is in place on the magnetic platform  10  to compensate for a problem with the second metatarsal bone and a toe crest pad  34  is in place on the magnetic platform  10  to compensate for a problem with the fourth phalange bone. 
         [0041]    Referring to  FIG. 11 , a side plan view of the second embodiment of the present invention will be described. In this example, the magnetic platform  10  is installed in the holding strap  16  and held to the wearer&#39;s foot  22  by the elastic cloth band  12  and extends at least partially beneath the arch of the wearer&#39;s foot  22 . The toe straps  14  limit the amount of rotation and front/back movement of the elastic cloth band, thereby holding the magnetic platform  10  in a relatively stable position with respect to the wearer&#39;s foot  22 . In the example shown, an arch support pad  50  is in place on the magnetic platform  10  to compensate for a problem with the wearer&#39;s arches. 
         [0042]    Referring to  FIGS. 12 and 13 , a side and top plan view of the third embodiment of the present invention will be described. In this embodiment, the magnetic platform  10  covers a substantial area of the inner sole of the user&#39;s shoe and is thereby held steady in relation to the shoe. Since the wearer&#39;s foot  22  is normally held steady within their shoe, this platform also holds the pads  30 / 40 / 50  in position with respect to the wearer&#39;s foot  22 . In this example, a toe crest pad  30  is in place on the magnetic platform  10  for compensating for an abnormality of the second phalange bone; a metatarsal pad  40  is in place on the magnetic platform  10  to compensate for a problem with the fourth metatarsal bone; and an arch support pad  50  is in place on the magnetic platform  10  to compensate for a problem with the user&#39;s arch. 
         [0043]    Referring to  FIG. 14 , an isometric view of the first and second embodiments of the present invention will be described. The magnetic platform  10  is attached to the elastic cloth band  12  by means known in the industry including, but not limited to sewing and gluing welding. In some embodiments, the elastic cloth band  12  completely encircles the wearer&#39;s foot while in other embodiments, the elastic cloth band  12  ends where it is affixed to the edges of the magnetic platform  10 . The toe straps  14  are affixed to the upper front edge of the elastic cloth band  12  by means known in the industry including, but not limited to sewing, gluing and welding. In embodiments where the elastic cloth band  12  completely encircles the wearer&#39;s foot, the toe straps  14  are affixed to the lower front edge of the elastic cloth band  12  by means known in the industry including, but not limited to, sewing, gluing and welding. In embodiments where the elastic cloth band  12  the elastic cloth band  12  ends where it is affixed to the edges of the magnetic platform  10 , the toe straps  14  are affixed to the upper surface of the magnetic platform  10  by means known in the industry including, but not limited to sewing, gluing and welding. In this example, a toe crest pad  30  and a metatarsal pad  40  are shown installed upon the magnetic platform  10 . 
         [0044]    Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result. 
         [0045]    It is believed that the system and method of the present invention and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
