Method and apparatus for making corrected custom foot molds

Claim 2

In apparatus for producing a corrected mold for a foot having a rear portion and a forefoot portion with a ball portion, said apparatus comprising: resilient cushion means for substantially immobilizing the ball portion and providing a floating action for the rear portion thereof when said foot is supporting its respective portion of full body weight, said resilient cushion means having a rear section with a first thickness for supporting said rear portion and a front section with a second, smaller thickness for supporting said forefoot portion, said rear section being deformable throughout the entire first thickness thereof to provide the floating action, the second thickness being sufficiently small such that said ball portion completely compresses said front section at the respective position of the ball portion to provide said substantial immobilization, wherein the position of the rear portion of the foot on the resilient cushion means is adjusted so that said resilient cushion means adopts a corrected contour of the foot; and molding means positioned between said foot and said resilient cushion means for producing said corrected mold once said foot has been so adjusted.

Claim 3

Apparatus according to claim 1, in which said molding means is comprised of a sheet of plastic which softens on heating and hardens on cooling.

Claim 4

Apparatus according to claim 1, in which said resilient cushion means includes an inner portion and at least one outer portion, said inner portion being at a higher level then said at least one outer portion.

Claim 5

Apparatus according to claim 1, in which said resilient cushion means includes an inner portion and includes an upper support surface which is inclined downwardly from said inner portion.

Claim 6

Apparatus according to claim 4, in which said upper support surface of said resilient cushion means is inclined downwardly from said inner portion with an angle which is not greater than 20°.

Claim 7

Apparatus according to claim 1, in which said resilient cushion means includes first and second sections, each section having a raised end portion, said raised end portions of said first and second sections being adjacent to each other, and each of said first and second sections being adapted to support a foot.

Claim 8

Apparatus according to claim 1, in which said resilient cushion means includes a front edge, and said front section of said resilient cushion means includes an upper surface which is inclined upwardly towards said front edge when said cushion means is not depressed.

Claim 9

Apparatus according to claim 1, in which said resilient cushion means includes an upper surface which is inclined upwardly from said front section to said rear section.

Claim 12

The method according to claim 9, in which said molding means is comprised of a sheet of plastic which softens on heating and hardens on cooling.

Claim 13

The method according to claim 9, in which said resilient cushion means includes an inner portion and an upper support surface which is inclined downwardly from said inner portion with an angle which is not greater than 20°.

Claim 14

In apparatus for producing a corrected mold for a foot having a rear portion and a forefoot portion, said apparatus comprising: resilient cushion means for relatively immobilizing the forefoot portion with respect to the rear portion thereof when said foot is supporting its respective portion of full body weight, said resilient cushion means having a rear section wth a first thickness for supporting said rear portion and a front section with a second, smaller thickness for supporting said forefoot portion, said rear section being deformable throughout the entire first thickness thereof, and said resilient cushion means including a front edge, and said front section, in order to stretch out the toes and to tighten the muscles of the foot to the extent that it makes the foot more stable, includes an upper surface which is inclined upwardly towards said front edge when said cushion means is in an undepressed state, wherein the position of the rear portion of the foot on the resilient cushion means is adjusted so that said resilient cushion means adopts a corrected contour of the foot; and molding means positioned between said foot and said resilient cushion means for producing said corrected mold once said foot has been so adjusted.

Claim 15

In apparatus for producing a corrected mold for a foot having a rear portion and a forefoot portion, said apparatus comprising: resilient cushion means for relatively immobilizing the forefoot portion with respect to the rear portion thereof when said foot is supporting its respective portion of full body weight, said resilient cushion means having a rear section wth a first thickness for supporting said rear portion and a front section with a second, smaller thickness for supporting said forefoot portion, said rear section being deformable throughout the entire first thickness thereof, and said resilient cushion means including a front edge, and said front section, in order to stretch out the toes and to tighten the muscles of the foot to the extent that it makes the foot more stable, includes an upper surface which is inclined upwardly towards said front edge when said cushion means is in an undepressed state, wherein the position of the rear portion of the foot on the resilient cushion means is adjusted so that said resilient cushion means adopts a corrected contour of the foot; and molding means positioned between said foot and said resilient cushion means for producing said corrected mold once said foot has been so adjusted.
