Definitions

  • the present invention relates to improvements in tridentate guard batons having a three-pronged tip piece fixedly attached to the tip of a guard stick, and involves a tridentate guard baton in which the three poles of the trident are rendered detachable/reaftachable.
  • Billy clubs well-known to date include not only rodlike nightsticks, but also compressible/extensible nightsticks made compressible/extensible by telescopically assembling a plurality of tubular pieces whose diameters differ. Since the telescopic components can be pushed into each other to shrink the overall length, the portability of telescopic nightsticks, which can be hung at the waist without getting in the way, is excellent.
  • the seizing fork is that, because it is employed by pressing it against the trunk of the human body, the fork is ineffectual against either hand of a criminal wielding a lethal weapon-in the case of an elongate lethal weapon in particular, there is instead a risk of being attacked.
  • This conventional example is a device in which a nightstick is accommodated within a tubular shank that is the shortened hilt of a seizing fork. During use, the nightstick is drawn out of the tubular shank of the seizing fork, and the device is employed with the seizing fork being gripped in one and the nightstick being gripped in the other, which would be not be convenient to manage.
  • the present inventors filed a patent application ( JP App. No. 2005-306858 ) for a three-pronged guard baton, as an improvement over the above-described conventional examples, featuring a three-pronged iron tip section formed by welding three iron pipes, spaced apart 120° viewed head-on and extending at approximately 45° viewed laterally, into position on the tip of an iron rod, and tip-protecting caps covering the tips of the three iron pipes, with the three-pronged tip being fixed to the tip of the guard baton.
  • the guard baton has a length of over 100 cm even when telescoped down, such that it is inconvenient to carry owing to its rather large size.
  • a guard baton with three detachable prongs comprises a guard stick and a three-pronged tip fixed to a tip of the guard stick.
  • the three-pronged tip includes three aluminum poles having rear ends to which stainless-steel screws are fixed, and a stainless-steel pole attachment member having a front surface on which three screw holes are formed. The stainless-steel screws fixed to the three aluminum poles are detachably screwed into the three screw holes.
  • the guard stick may be made of wood or metal, and it is preferable that it be a metallic telescopic guard stick.
  • the guard baton with three detachable prongs according to the present invention has a light three-pronged tip because of aluminum and a strong connection portion because of stainless steel, the baton is highly rust-resistant and is useful for dealing with crimes using a knife because of both features. As a result, with the guard baton according to the present invention, it is possible to realize both effects of protecting a user and taking control of the criminals simultaneously.
  • Fig. 1 includes an external side view A of a three-pronged guard stick in an extended state according to the present invention and an external side view B of the three-pronged guard stick in a contracted state;

  • Fig. 7 is a sectional view of the detachable three-pronged tip 1 and the intermediate pole 11 fixed to each other;
  • Fig. 8 is a sectional view of the main pole 16 which is covered with the rear end protection cap 19.
  • a three-pronged tip includes three aluminum poles having rear ends to which stainless-steel screws are fixed, and a stainless-steel pole attachment member having a front surface on which three screw holes are formed at 120° intervals seen from the front and extend forward at about 45° seen from the side.
  • the stainless-steel screws fixed to the three aluminum poles are detachably screwed into the three screw holes.
  • the three-pronged tip is fixed to a tip of a guard stick, thereby realizing a guard baton with three detachable prongs.
  • This embodiment is an example in which a metallic two-stage telescopic guard stick is used as a guard stick and a three-pronged tip is detachably fixed to a tip of the stick.
  • a guard baton with three detachable prongs is made up of a three-pronged tip 1, an intermediate pole portion 2, and a main pole portion 3.
