Definitions

  • the invention relates to a defense device with the features of the preamble of patent claim 1.
  • the arrangement of the mechanical and electrical means used to trigger effective energy surges is tailored to the gun mode.
  • a piezo crystal unit was combined with storage elements (capacitors) for electrical charges.
  • the partial electrical charges generated by moving the pistol grip designed as a massive lever arm against the piezo element are added up in the capacitors to form an "effective charge". In the event of a defense, the total charge is triggered separately.
  • GB-A-21 70 056 an electrical treatment device is presented which has a pistol-like shape and a rod shape.
  • the piezo element used here is located in an independent tubular housing.
  • the generation of an electrical charge takes place in that a pressure part exerts a directed force on a shock transmitter, which in turn is moved towards the piezo unit.
  • the charge energy generated is introduced or passed through a cap that is axially movable by means of a retaining ring.
  • the pulse strength is regulated via the axial mobility of the cap.
  • the defense device should be able to be used effectively by both physically inferior and physically superior people.
  • At least one compressible piezoelectric element is arranged on the opposite end of the body with respect to the handle and which emits high-voltage and low-power electrical current when compressed, makes it possible for an attacker to give an electric shock if 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 or attackers without further preparations, and on the other hand creates 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 for 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 different 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 so 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 attachment of the cap ( 6) is covered by this.
  • the cap (6) encompasses 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 travel 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 together thus 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 to be axially movable on the first cap (13), whereas the cap (13) is to be placed over the dome-shaped part (7) of the tip (2) of the pocket umbrella (1).
  • 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).
  • FIG. 3 shows the tip (24) of a knife sheath (18) 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 the force (8) causing the compression of the piezoelectric element (21) is canceled, 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 the electrical discharge is thus 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 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 persons fended off or touched with it.
