Definitions

  • the present invention relates to a rotating apparatus using a magnet, and more particularly to a rotating apparatus using a magnet, which allows several passive magnets to be independently rotated using a single movable magnet, and a rotating decoration using the same.
  • a conventional rotating apparatus using a magnet has a structure in which a passive magnet, coupled with a movable magnet by magnetic force, is rotated by the rotation of the movable magnet using a driving motor.
  • the above rotating apparatus is mainly used in case that an output shaft of the driving motor cannot be directly connected to an object to be desired to rotate.
  • the output shaft of the motor cannot be directly connected to the rotary shaft of the rotating object using a power transmission device, such as a gear or a pulley.
  • the rotary force of the driving motor is transmitted to the passive magnet coupled with the movable magnet by the magnetic force by employing a rotating apparatus using a magnet, even though a nonmagnetic intermediate member, which does not affect the magnetic force, is interposed between the movable magnet and passive magnet.
  • a rotating apparatus using the magnet is widely employed by a stirring machine used in a chemical laboratory and a toy as well as a power transmission device of machinery.
  • the above-described rotating apparatus using the magnet is constructed such that one movable magnet connected to an output shaft of a driving motor is rotated and one passive magnet coupled with the movable magnet by magnetic force is rotated by the rotation of the movable magnet. That is, in order to rotate the passive magnet, the movable magnet should be connected to the motor and rotated thereby. Accordingly, in case that objects desired to rotate are prepared in a plural number, plural movable magnets respectively corresponding to the rotating objects are required, and the plural movable magnets are connected to the driving motor by gears or pulleys.
  • the number of components, such as shafts, belts, gears or chains, for rotating the plural movable magnets increases in proportion to the number of the rotating objects.
  • the increase of the number of the above components complicates the structure of the rotating apparatus, deteriorates assembling efficiency of the rotating apparatus, increases noise, and causes frequent defects of the rotating apparatus due to mechanical abrasion of the components. Further, the increase of the number of the above components increases loss of power due to rolling friction of the components, thereby lowering energy efficiency.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a rotating apparatus using a magnet, in which one movable magnet and a plurality of passive magnets coupled with the movable magnet by magnetic force are independently rotated so that a plurality of rotation bodies are rotated by the movable magnet, thereby reducing the number of components required by machinery.
  • the movable magnets are not directly rotated, but the movable magnets and a separating member interposed between the passive magnets and the movable magnets are shifted relatively to each other. Further, the passive magnets are shifted on the separating member along the movable magnets and simultaneously rotated.
  • the rotating apparatus of the present invention is used in a toy, an interior decoration, an advertising sign, etc., it is possible to have various visual effects such as a cubic effect and the feeling of movement.

  • a rotating apparatus using a magnet comprising: a nonmagnetic separating member; at least one movable magnet relatively shifted from the separating member along one surface of the separating member, any one of N-pole and S-pole of the movable magnet being arranged along the one surface of the separating member; a nonmagnetic isolating member placed on the other surface of the separating member at a position opposite to the movable magnet along the route formed by relative shift of the movable magnet and the separating member; and at least one passive magnet placed beside the isolating member on the other surface of the separating member, the passive magnet being coupled with the movable magnet by magnetic force, and rotating on the other surface of the separating member while moving along the movable magnet when the movable magnet and the separating member are shifted relatively to each other.
  • the movable magnets and the passive magnets used in the rotating apparatus of the present invention may be preferably permanent magnets, and more preferably neodymium magnets consisting of neodymium, iron dioxide, and boron.
  • the movable magnets and the passive magnets may have various shapes such as a circle, a square, a ring, etc.
  • the separating member may be interposed between the movable magnets and the passive magnets to prevent the direct absorption of the movable magnets and the passive magnets.
  • the separating member may be made of a material not to be affected by magnetic force of the movable magnets and the passive magnets.
  • the separating member may be made of a nonmagnetic material such as aluminum stain, synthetic resin, and glass.
  • the rotation of the passive magnets of the rotating apparatus of the present invention is divided into two types, i.e., one type, in which shifting surfaces of the passive magnets on the separating member are parallel with rotating surfaces of the passive magnets (hereinafter, referred to as “horizontal rotation"), and the other type, in which the shifting surfaces of the passive magnets on the separating member are perpendicular to the rotating surfaces of the passive magnets (hereinafter, referred to as "rolling rotation").

  • the passive magnets are rollingly rotated, it is preferable that the passive magnets have cylindrical or disk shapes to have the circular cross-section thereof. In case that the passive magnets are installed in a separate rotation body, which can be rolling rotated, the passive magnets may have other shapes.
  • the movable magnets and separating member of the rotating apparatus of the present invention are shifted relatively to each other, thus being displaced against each other. That is, the movable magnets are fixed and the separating member is shifted, or the separating member is fixed and the movable magnets are shifted.
  • the rotating apparatus of the present invention may further comprise driving means for shifting the movable magnets relatively to the separating member.
  • the driving means is one selected from the group consisting of a conveyor device, a crank mechanism and a cam mechanism.

Abstract

La présente invention concerne un appareil rotatif à aimant. L'appareil rotatif de l'invention comprend un organe de séparation, au moins un aimant mobile, et au moins un aimant passif. L'organe de séparation, réalisé dans un matériau non magnétique, est intercalé entre l'aimant mobile et l'aimant passif. L'aimant mobile est relativement décalé par rapport à l'organe de séparation le long d'une surface de l'organe de séparation, et le pôle N et le pôle S de l'aimant mobile sont agencés le long de ladite surface de l'organe de séparation. L'aimant passif est placé sur l'autre surface de l'organe de séparation, et couplé à l'aimant mobile par une force magnétique. Lorsque l'aimant mobile et l'organe de séparation sont décalés l'un par rapport à l'autre, l'aimant passif glisse le long de l'aimant mobile et tourne sur l'autre surface de l'organe de séparation. L'appareil rotatif de l'invention peut être appliqué à un jouet, à une décoration vestimentaire, à une décoration d'intérieur, et à un panneau publicitaire, de même qu'à un dispositif de transmission d'énergie dans une machine nécessitant une pluralité d'arbres rotatifs.
