Definitions

  • the present invention relates to a system for projection into the air of light elements, in particular paper or plastic, for example confetti or coils, during festive events.
  • a projection system corresponds to the product marketed by the company Brezac Artifices under the brand Kabuki.
  • a projection system consists of a base on which is fixed a compressed gas cartridge.
  • a tube containing the light elements to be projected in the air is mounted on the base so as to receive the gases supplied by the cartridge.
  • a striker that can be operated manually or automatically is adapted to pierce the cartridge. The released gases then spread in the tube and throw the light elements into the air.
  • a disadvantage of such a projection system is that it is difficult to ensure, at each use, optimal drilling of the cartridge. Indeed, the amplitude of the kinetic energy that can be transmitted to the firing pin to ensure the opening of the cartridge is generally limited. Indeed, when the projection system is manually operated, the firing pin is set in motion directly by a user, for example by pulling a string. The amplitude of the energy transmitted to the striker is then limited by the energy that can develop the user. When the projection system is actuated automatically, the striker is generally connected to a spring, maintained in the compressed state by a locking means actuated by an electromagnet. The spring is released when the electromagnet receives a control signal. However, the low mass of the firing pin and the space constraints limit the amplitude of the kinetic energy that can be transmitted to the firing pin.
  • the present invention aims to obtain a light element projection system, using a compressed gas cartridge, improving the opening of the cartridge by the striker.
  • the present invention also aims to obtain a light element projection system in which the replacement of the compressed gas cartridge is simple and fast.
  • the present invention provides a system for projecting light elements in the air according to claim 1.

  • the opening comprises a shoulder for locking the slide in the stop position.
  • the slide comprises a body and at least one reinforcement connected to the body by a tab extending in a determined direction, the opening comprising a shoulder adapted to receive the reinforcement to block the slide to the cocking position, the tab being deformable to release the reinforcement of the shoulder.
  • the system comprises a base disposed at one end of the opening, the striker being fixed to the base, the base comprising at least one protrusion adapted to cooperate with the slide to place the slide in the arming position.
  • the opening is cylindrical, the base being adapted to be pivoted relative to the housing from a first position in which the base prevents sliding of the slide to a second position in which the slide is free to slide.
  • the reservoir is fixed to the base, said base comprising openings for the passage of the gases released during the opening of the cartridge.
  • the housing comprises at least one manually operable flexible blade adapted to deform the tab to release the reinforcement of the shoulder.
