Definitions

  • the invention relates to a contact shoe with a sole made of electrically conductive material, which is provided with a flexible body contact strip made of electrically conductive material, which is at least electrically connected to the sole.
  • Contact shoes of the type described above are used by people who handle and assemble sensitive electrical components in order to ensure that they have the same electrical potential or the same electrical charge state as their surroundings. Sensitive ICs are easily destroyed when touched by hand if the persons mentioned have a different electrical potential than the ICs.
  • the potential of the IC's is usually that of the environment, that is, that of the soil or the earth.
  • a contact shoe made from flat belt parts; however, these must be connected to each other at the crossing points by seams or by welding.
  • US Pat. No. 3,359,456 to slip a strap of electrically conductive material sewn together into a ring over the front part of a shoe.
  • the ring-shaped straps that span the shoe are sewn to the underside of the shoe with a body contact band, which is also made of electrically conductive material.
  • the body contact band is either inserted into the shoe via the heel or connected to the ankle of the foot via a further strap shaped into a ring.
  • the same applies to a strap shaped into a ring (FR-A-2 082 773 Fig. 2), although it can be seen that the ring-shaped strap spanning the front part of the shoe on the one hand and the body contact band on the other hand are two different parts, that have to be connected in some way, but the type of connection is unknown.
  • the invention has for its object to provide a contact shoe of the type described above, which is particularly simple and inexpensive to manufacture.
  • the contact shoe is designed in the manner of a sandal and consists of a base plate with straps emanating from the top, and that the base plate and the straps consist of a single continuous piece of flat material.
  • the contact shoe is particularly advantageous to design the contact shoe as an overshoe to be pulled over a normal shoe.
  • a sensitive component handling or assembling person does not even have to take off their normal shoes, but can pull the overshoes over one or both normal shoes.
  • the contact shoe is made of electrically conductive material.
  • This can be, for example, leather, rubber, polyethylene or another flexible material that is enriched or impregnated with carbon or another conductive substance.
  • a rear strap and a lateral strap emanate from the heel part of the footplate, that a front strap and two lateral straps extend from the forefoot part of the footplate, that the four side straps, which extend from the forefoot part, are fastened to the front straps, and that the straps extending from the heel part and the front straps have slots through which the body contact strip is passed.
  • the side straps extending from the forefoot part should be provided with several adjustment holes in order to adapt the contact shoe or contact shoe cover to the person's foot or normal shoe.
  • the body contact band should also be provided with a plurality of adjustment holes in order to be able to adapt it closely to the body part in question, without causing a constriction.
  • a suitable part of the body is, for example, the narrowing of the legs between the knee and calf muscle.
  • the body contact band should be long enough to reach the belly area of the person wearing the contact shoe. This is useful, for example, for women who wear tights.
  • the body contact tape can then be placed around the waist.
  • the contact overshoe shown in FIG. 1 is designed in the manner of a sandal which the person concerned wears over a normal shoe.
  • the shoe cover consists of a footplate 1.
  • Two side straps 9, 11 and a rear strap 10 extend from the heel part 3 of the footplate 1.
  • From the forefoot part 2 of the Base plate 1 go out of a front strap 6 and four side straps 4,5,7,8.
  • the two side straps 4 and 8 on the one hand and the two side straps 5 and 7 on the other hand are brought together over the base plate and fastened to the front strap 6 by means of button-like fastening elements 13, 14.
  • the straps 4,5,7,8 have, as can be seen in FIG. 2, push-through holes for the button-like fastening elements 13, 14.
  • the four rear straps 9, 10, 11 and the front strap 6 are also provided with push-through slots 16 for a body contact band 12.
  • the body contact band 12 has at one end adjustment holes 17 through which a button-like fastening element 18 can be passed, so that the body contact band 12 with its area passed through the slots 11 forms a fastening loop which binds the feet of those wearing the shoe cover Person spanned.
  • the body contact strip 20 has adjustment holes 20 at its end, through which a button-like fastening element 19 is inserted.
  • the basic section of the sandal-shaped shoe cover shown in FIG. 2 consists of one piece and is cut out of flat material.
  • the flat material is elastic and electrically conductive. It consists for example of leather, rubber, polyethylene or another flexible material which is enriched or impregnated with carbon or another conductive substance.
