Definitions

  • the yieldingly extensible string passes through the strip at regularly spaced points of its length considered in its non-extended state, whereby the non-extensible strip is adapted to be folded after the manner of an accordion or of a concertina over the string and is thus permanently connected with the latter at the passages provided therefor through it, which allows these mutual displacements and an easy separation between them.
  • Fig. 1 shows one end of the extensible electric conductor.
  • Fig. 2 is a cross-section through line 2-2 of Fig. 1.
  • Fig. 3 is a plan view of the inextensible strip carrying the electric leads.
  • the strip or ribbon 2 serves as a non-extensible support for the electric leads which p ass out of said strip as shown, three in number, at II, I2, and I3, said leads being distributed throughout the breadth of the strip while suitable care is exercised for obtaining isolation as required by the conditions of use.
  • the ribbon or strip 2 whether plaited, woven or knitted is carefully folded, the number of folds being equal to half the number of buttonholes 3, which latter are distributed after folding along two lines A and B.
  • an extensible electric conductor comprising a folded supporting strip of non-extensible material and provided with a series of openings located at the folds and distributed throughout its length, electric wires carried by said strip and adapted to follow the deformations thereof and two elastic strings passing respectively through the two buttonholes of all the even and of all the odd pairs of successive buttonholes at the folds to either side of the folded strip, said strings 3 lying in parallel relationship in their unextended inoperative state and bearing against the outer surface of the extreme folds of the strip through their corresponding ends for allowing the simultaneous longitudinal deformations of the strings and of the strip arrangement.
  • An extensible electric conductor comprising a folded supporting strip of non-extensible material and provided with a series of openings located at the folds and distributed throughout its length, electric wires carried by said strip and adapted to follow the deformations thereof and a looped string the two strands of which pass respectively through the two buttonholes of all the even Aand of all the odd pairs of successive buttonholes at the folds to either side of the folded strip, said strands lying in parallel relay tionship in their unextended inoperative state and the looped end of the string bearing against the outer surface of the extreme fold at one end of the strip and means for causing the free ends of the strands to bear against the outer surface of the other extreme fold.
