Abstract

Abstract An apparatus for molding the soles and uppers of various types of footgear to the contours of individual feet, said apparatus comprising multiple, individual, complete elements, each of said elements comprising impervious structure for receiving, maintaining, retaining and withdrawal of molding material; said structure defining an end port piece with valve-like action to maintain closure while permitting selective insertion and withdrawal of molding material; a flexible bag to receive and contain said molding material; a connecting part between said end port piece and said flexible bag, where said connecting part is a flat tube-like structure of unique construction, said unique construction permitting passage and retention of molding material without any readily apparant increase in cross section; where the number of said elements employed varies with the type of footgear; and where the shape and size of each element varies with its location in said footgear, and where said shape and size of each of said connecting parts varies to permit the location of end port pieces in any desirable part of the footgear; and where said molding material is of a non-setting matter such as water or air.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 112 words
Apparatus for providing footgear with comfortable individualized molded support, said apparatus comprising a plurality of independent flexible impervious liquid proof bag structures for retaining a non-setting free flowing fluid; each bag structure having a conduit extending therefrom terminating in a port constructed to maintain closure of said element while permitting selective insertion or withdrawal of said non-setting fluids said bag structure being located in the footgear with respect to the foot of the wearer to provide individual areas of the foot with external pressure and support said bags and connecting parts being secured to an overriding innersole, said overriding innersole having means for adherence to the sole and upper of said footgear.
Claim 2
Dependent Claim 112 words
Apparatus for providing footgear with comfortable individualized molded support, said apparatus comprising a plurality of independent flexible impervious liquid proof bag structures for retaining a non-setting free flowing fluid; each bag structure having a conduit extending therefrom terminating in a port constructed to maintain closure of said element while permitting selective insertion or withdrawal of said non-setting fluids said bag structure being located in the footgear with respect to the foot of the wearer to provide individual areas of the foot with external pressure and support said bags and connecting parts being secured to an overriding innersole, said overriding innersole having means for adherence to the sole and upper of said footgear.
Claim 3
Dependent Claim 15 words
Apparatus as defined in claim 1, where said ports are securely embodied in said footgear.
Claim 4
Dependent Claim 21 words
Apparatus as defined in claims 1 and 2, where said ports are set flush with the outer surfaces of said footgear.
Claim 5
Dependent Claim 24 words
Apparatus as defined in claim 1, where said ports are of such configuration as to permit use in conjunction with hypodermic syringes and needles.
Claim 6
Dependent Claim 82 words
Apparatus as defined in claim 1, where said bag structures are selectively shaped to give individually supportive pressure, at least to such areas generally under the proximal to the second, third, fourth and fifth Metatarsel-Phalangeal joints, the area immediately distal and medial to the Clacaneal bone, the area distal and lateral to the Calcaneal bone, the posterior medio-lateral periphery of the heel, the tongue of the footgear, the medial and lateral sides of the footgear, the area under the First Metatarsal-Phalangeal joint.
Claim 7
Dependent Claim 41 words
Apparatus as defined in claim 1, where the connecting conduits comprise flexible tubes that folding a said conduit upon itself and adhering same to inner aspects of footgear will achieve closure of said conduits with retention of fluids within said elements.
Claim 8
Dependent Claim 33 words
Apparatus as defined in claim 1 wherein said free flowing non-setting fluid is selected from the group of liquids consisting of water, water solutions, oils, anti-freeze mixtures, fluids containing finely divided solid material.
