Definitions

  • the invention relates to a defense device with the features of the preamble of patent claim 1.
  • the invention is therefore based on the object of providing a defense device with which physically inferior persons can effectively defend themselves against any attack as well as physically inferior persons without seriously injuring the opponent.
  • At least one compressible piezoelectric element is arranged at the opposite end of the body with respect to the handle and emits high-voltage and low-power electrical current when compressed, it is possible to give an attacker an electric shock when a minimum distance is exceeded , so that the attack can be warded off effectively.
  • the piezoelectric elements are arranged on the body in a compressible manner in the longitudinal direction, this ensures that the body is not initially prepared accordingly for the purpose of self-defense, but is always ready for use.
  • the piezoelectric elements are arranged inside or behind a tip which can be displaced relative to them, this ensures that the piezoelectric elements or the mechanism used for self-defense is adequately protected against external influences and that the piezoelectric element is compressed only in one case appropriately directed force is caused.
  • the movable tip is a cap covering the piezoelectric elements and containing at least one opening at the outer end, this ensures on the one hand that the corresponding electrical charge can be given to the attacker (s) without further preparations, and on the other hand protection against damage which is characterized by high efficiency and high efficiency and can be produced in a simple and inexpensive manner.
  • the piezoelectric elements are arranged between two telescopically movable, matching caps, of which the inner one can be detachably plugged onto the outer end of the rod-shaped or stick-shaped device, this creates the possibility of the corresponding assembly also being used with different rod-shaped or stick-shaped devices
  • the assembly can e.g. B. come in different pocket umbrellas without it being necessary to provide new assemblies for any existing pocket umbrellas.
  • the pocket umbrella (1) has a tip (2), in the interior of which a piezoelectric element (3) protruding from the tip (2) is arranged.
  • the piezoelectric element (3) is cylindrical and has a contact (5) at its end (4) facing away from the pocket umbrella tip (2).
  • a cap (6) is designed such that it can be placed over the tip (2) of the pocket umbrella (1) containing the piezoelectric element (3), so that the dome-shaped part (7) of the tip (2) of the pocket umbrella (1) after the cap () 6) is covered by this.
  • the cap (6) engages around the dome-shaped part (7) of the tip (2) in such a way that it acts under pressure, represented by the arrow (8), on the tip of the cap (6) to axially displace the cap (6). from a first position in the direction of the end of the screen (1) opposite the tip (2), ie in a second position.
  • the axial movability in the direction of the end of the pocket umbrella (1) opposite the tip is limited by the ring (9) which is formed in one piece with the dome-shaped part (7) and thus together forms the tip (2) of the pocket umbrella (1).
  • the contact (5) engages with a hole (12) in the cap (6), so that the electrical charge of approximately 20,000 to 30,000 volts with a low amperage at the same time via the contact (5) and that in the cap (6 ) located hole (12) to the object in contact with the cap (6) or the hole (12) or the person in contact with it.
  • the piezoelectric element (3) is not inserted into the tip (2) of the pocket umbrella (1), but is arranged on a cap (13) such that the bottom (14) of the piezoelectric element (3 ) is also secured against axial displacement in the direction of the folding umbrella handle.
  • the cap (13) is enclosed by a second cap (15) so that the piezoelectric element (3) is arranged between the first cap (13) and the second cap (15) and the contact (16) of the piezoelectric element with a hole (17) in the second cap (15) is in contact.
  • the second cap (15) is arranged on the first cap (17) so as to be axially movable, whereas the cap (13) is to be placed over the dome-shaped part (7) of the tip (2) of the pocket umbrella (1).
  • the two caps (13, 15) are attached to the dome-shaped part (7) of the tip (2) by applying the first (13) of the two caps (13, 15) an axial force (8) in the direction of the umbrella tip (2) exerted on the cap (15), there is an axial displacement of the cap (15) in relation to the cap (13) and thus to a compression of the piezoelectric element (3), so that the contact (16) and in the hole (17) located in the cap (15) is given an electrical charge to the object causing the force, the electrical charge being a charge with a high volt and low amperage.
  • the displacement of the cap (15) in relation to the first cap (13) is limited by stops (not shown here) arranged inside the cap (15).
  • the second cap (15) is returned to its starting position by means of spring mechanisms, also not shown here, so that the compression of the piezoelectric element (3) is removed and there is no further electrical discharge.
  • the first and second cap (13, 15) form a structural unit which is to be removed together from the tip of the pocket umbrella (2).
  • the tip (24) of a knife sheath (18) is shown, which is also to be provided with a structural unit consisting of a first cap (19) and a second cap (20).
  • the first cap (19) has a piezoelectric element (21) that also prevents axial displacement is secured and has a contact (23) which is in contact with a hole (23) in the second cap (20).
  • the structural unit consisting of the essentially first and second cap (19, 20) is to be applied to the tip of the knife sheath (18).
  • the cap (20) After removal of the compression (8) causing the compression of the piezoelectric element (21), the cap (20) is caused to return to its starting position by a spring mechanism, not shown here and located in the cap (20), so that it the compression of the piezoelectric element (21) is canceled and thus the electrical discharge is canceled. The device is thus again ready to be able to emit an electric shock when pressure is exerted.
  • the outer cap (15 or 20) is in each case provided with a shape (24 or 25) which extends over the piezoelectric element (3) arranged on the inner cap (13 or 19) or 21) fits.
  • the piezoelectric elements can be commercially available piezo high-voltage igniters, for example piezo elements supplied by the Robert Bosch GmbH, Junkers division.
  • the defense device has been described above in connection with a pocket umbrella and an adventure knife, it can also be designed as a separate device which is to be attached to existing rod-shaped objects such as sticks, umbrellas, adventure knives and batons.
  • the device according to the invention is also well suited for police purposes, because its use causes practically no injuries to people fended off or touched with it.
