Definitions

  • the present invention relates in a first aspect to a cord cover for concealing excess cord of an electric male plug.
  • the present invention relates to an electric male plug comprising a cord cover according to the first aspect of the invention.
  • the present invention relates to an electric apparatus comprising an electric male plug according to the first aspect of the invention.
  • the present invention relates to a use of the cord cover according to the first aspect of the invention or of a electric male plug according to the second aspect of the invention for an electric apparatus.
  • sockets for supplying electric voltage to which various electric apparatuses may be connected.
  • Such sockets are usually arranged in the walls of the building.
  • Sockets usually comprises two or three holes within which metal bushing are accommodated, which are connected to the grid.
  • an electric apparatus comprises a connecting cord, one end of which comprises an isolated housing and two or more electrically conducting pins having dimensions that are adapted to the holes in the socket.
  • a connecting cord one end of which comprises an isolated housing and two or more electrically conducting pins having dimensions that are adapted to the holes in the socket.
  • Excess cord will thereby be aesthetically undesirably and will also be able to represent a safety hazard in that one's movements unintentionally could grab the excess cord whereby one may fall or whereby the electric apparatus may tip over.
  • loose excess cord may pose to be a hygienic problem in that such a cord is an element that has a tendency to attract dust and grease.
  • FR 2 711 017 discloses a wire storage box.
  • This wire storage box comprises a box having a lid to be mounted on the box.
  • the box furthermore comprises a cut-out into which a cord may be arranged.
  • the box on one of its surfaces comprises one or more holes, into which a bushing may be arranged.
  • This bushing extends from that surface and comprises holes which are adapted to an electric male plug in a way that when the bushing is arranged in the associated hole in the box, a plug can be led into the box and further into the interior of the bushing and the pin of the male plug may subsequently be led through the holes in the bushing itself and hereafter the electric plug with the associated wire storage box can be arranged into a socket.
  • the cord is arranged in the cut-out of the box.
  • the interior of the box is large enough for winding up a certain length of cord and thereby the cord of an electric apparatus may be adapted to the desired length, when the male plug of the apparatus is arranged into the box and the bushing as described above.
  • the wire storage box disclosed in FR 2 711 017 has the disadvantage that it is rather large and clumsy and not suitable for the type of sockets which comprise a depression into which an electric plug may be arranged and which thereby will surround the housing of the plug.
  • the cut-out through which the wire is being led, implies inflexibility limitations as to in which orientation the cord is entered into the box, because the wire storage box in FR 2 711 017 only allows one orientation due to the fixed cut-out.
  • This objective is achieved according to the present invention in its first, second, third and fourth aspect, respectively.
