Rubber Overshoe Patents (Class 12/142EV)
  • Patent number: 6067731
    Abstract: A novel shoe cover for medical uses comprises a one piece unit of thin elastomeric material having a pair of side panels in substantially parallel relation to each other. Each of the side panels has a foot shaped portion, an ankle shaped portion and an outer perimetric edge. A bead shaped perimetric section joins the two side panels at their respective perimetric edges, except at an upper edge of the ankle portions. A traction enhancing embossed pattern is formed on a lower portion of the foot shaped portion of the side panels. A novel method for forming the shoe cover comprises providing a shoe cover form which has substantially parallel lateral sides and a peripheral edge thereabout, which comprises a foot forming portion and an ankle forming portion, which has recesses covering substantially all of the foot forming portion of the first and second sides, and which has a textured surface on a lower portion of the foot forming portion.

  • Patent number: 5329701
    Abstract: A tool is used to custom fit rubber slip-ons onto golf shoes for use in wet conditions to keep the feet of the golfer dry. The tool can be manually manipulated to cut openings into the sole of a slip-on of an appropriate size so that the openings are aligned with the spikes of the golf shoe. When openings have been cut for all of the spikes, the sole of the slip-on rests against a base of the spikes and the sole of the golf shoe. The tool has an elongated hollow body with two ends. One end has a circular cutting edge thereon and the other end has a handle thereon. After the slip-on is placed onto the golf shoe with the spikes separating the sole of the slip-on from the sole of the golf shoe, the tool is aligned with each spike in turn to cut an appropriate opening for that spike. Previously, slip-ons have been designed with pre-cut openings but these slip-ons can only be used with a specific model of golf shoe of a specific manufacturer having a specific size.

  • Patent number: 4703533
    Abstract: The present invention provides a rubber footwear vulcanizate to which there may be separately affixed an outsole. The vulcanizate may be suitably manufactured from an assembly of an uncured rubber upper, insole, welt and a vulcanized midsole base article. The inner and outer surfaces of the midsole base article may be suitably roughened and the surface interfacing the uncured assemblage precoated with an uncured rubber. The assembled uncured rubber footwear components may be vulcanized into a vulcanizate footwear product of a unitary construction. The outer surface midsole surface permits a wide variety of compositionally differing outer soles to be separately secured thereto.

  • Patent number: 4218797
    Abstract: A method of making footwear having an upper the lower edge of which is embedded in a sole of elastomeric composition compounded to set in a mold cavity at room temperature and pressure. The upper comprises a loop of elastic fabric stretched to embrace the perimeter of a male mold with one edge curled inwardly and impaled over pointed pins supported on a male mold and some of which pins act to hold the two mold members properly spaced apart while the elastomer cures.

  • Patent number: 4180872
    Abstract: An improvement for waterproofing a prosthetic foot of the type having a foot body surrounding a keel includes a layer of water repellent resilient material cemented to a bottom surface and front, rear and side edges of a lower portion of the foot body extending from the toe to the heel and a coating of water repellent material covering the top portion of the foot body and the interface of the edges of the layer of water repellent resilient material with the lower portion of the foot body such that the prosthetic foot can be immersed in water while the water is prevented from reaching the keel.

  • Patent number: 3987510
    Abstract: An article of footwear and a method of making the same which comprises forming a length of elastic webbing into a ringlet and embedding the lower longer edge of the "upper" so formed in elastomeric composition which takes a set at low temperature to form a unitary sole and heel inseparably bonded to the elastic upper. If the sole is made to be worn over athletic shoes of the type equipped with spikes or cleats, the interior of the sole is molded to provide cavities accommodating such spikes or cleats. The rims of these cavities bear against and support the rim areas of the sole and heel of an athletic shoe thereby preventing the spikes from penetrating the sole of the footwear. The elastic webbing is tailored to shape merely by forming a dart crosswise of the midportion of the toe end thereof.
