Definitions

  • the present invention relates to an electric knife intended in particular for the opening of oysters and more particularly such a knife of the type comprising a housing, a blade capable of sliding in its longitudinal direction between an extended position relative to the housing and a retracted position relative to the housing, and an electromagnet mounted in the housing and arranged to vibrate the blade between its two positions.
  • the present invention aims to overcome this drawback.
  • the invention relates to an electric knife intended in particular for opening oysters, of the type comprising a housing, a blade capable of sliding in its longitudinal direction between an extended position relative to the housing and a retracted position by relative to the housing, and an electromagnet mounted in the housing and arranged to vibrate the blade between its two positions, characterized in that it comprises a cam mounted to rotate on the housing, said cam being capable of vibrating in rotation under the action of the electromagnet between a first position where it requires the blade to be in the extended position, and a second position where it allows the blade to return to its retracted position.
  • the cam when the cam vibrates under the action of the electromagnet, it drives the blade towards its extended position when it takes its first position, then allows the blade to return to its retracted position under the effect of the pressure exerted by the user when it returns to its second position.
  • the knife according to the invention comprises first elastic means keeping the cam close to its second position in the absence of magnetic forces.
  • the cam remains in this second position as long as the electromagnet is not energized. As soon as the latter is excited, the electromagnetic forces attract the cam towards its first position, which has the effect of initiating the vibration movement which can be transmitted to the blade.
  • Second elastic means can also be provided to return said blade to its extended position.
  • the ratio of the distance between the axis of rotation of the cam and the air gap of the electromagnet on the one hand, to the distance between the axis of rotation of the cam and its part acting on the blade on the other hand, is between two and three to optimize the operation of the knife according to the invention.
  • the figure shows the housing 1 of the device inside which is mounted an electromagnet 2 supplied by a power cord 3 in known manner.
  • the electromagnet 2 comprises two pole pieces 4 having cylindrical surfaces 5 centered on an axis 6.
  • a cam 7 is rotatably mounted in the housing 1 around a shaft 8 also centered on the axis 6.
  • a permanent magnet 9 is fixed to the cam 7 with its two poles facing the pole pieces 4 of the electromagnet 2 when the cam is in a first position shown in the drawings in solid lines.
  • Two compression springs 10 tend to separate the cam 7 from this first position to keep it in balance, in the absence of magnetic forces, in a second position shown in the drawing in phantom.
  • the cam 7 has a cam surface 11 capable of cooperating with the heel 12 of a blade 13 slidably mounted in the housing 1 between a crimped position shown in solid lines and a retracted position shown in broken lines.
  • Compression springs 15 acting between the shoulders 16 of the bootmaker and the heel 12 of the blade 13 tend to keep this blade in its extended position.
  • the knife 13 Due to the shape of the cam surface II which has a projection 17, the knife 13 is also held in its extended position by the cam 7 when the latter is in its first position.
  • the blade 13 remains in its extended position under the action of the springs 15 and does not receive the vibrations of the cam.
  • the springs 10 could be replaced by a spiral spring or even possibly eliminated.
  • the cam 7 has been shown acting directly on the heel of the knife 13, but an intermediate piece could obviously be added.
