Definitions

  • the object of the present invention is, as the title of the invention states, a monolithic expanding projectile, or one could also speak of a bullet used in hunting which has the particularity that it opens or expands during impact with a very high efficiency due to the aid offered by the material with which the projectile is crowned.
  • the present invention is characterised by the special design, configuration and materials used in each part of the project, which has the particularity of being a monolithic expanding projectile that is free of lead and plastic polymers, which facilitates aerodynamics in flight and subsequent expansion once it hits the target.
  • the present invention falls within the scope of the elements used in hunting as bullets or projectiles.
  • the object of the present invention is to develop a projectile which does not degrade the environment, i.e.. which is free of plastics and lead, which ensures the expansion of the projectile when it hits the target, by developing a projectile as described below and set out in its essentiality in the first claim.
  • the object of the present invention is a monolithic expanding projectile comprising a cylindrical body which at one end thereof continues with a decreasing diameter forming a conical area which is finished at its tip with a spherical element, where the conical body has a perforation, preferably cylindrical, which runs approximately from the base of the conical area to the free end of the conical area and where the spherical element of higher toughness and hardness than the copper material from which the projectile is made is attached.
  • Both the cylindrical body and the conical area, except for the perforation made in the conical area, are solid, preferably made of copper, while the spherical element at the end of the conical area is made of a harder and tougher material than the material of manufacture of the cylindrical body and the conical area, preferably, but not limited to, steel of lower hardness than that used in the manufacture of the barrel of the weapon.
  • the cylindrical body has a series of annular grooves on its outer surface, separated from each other, followed by ridges.
  • friction relievers or grease nipples as they are elements that reduce friction in the barrel tube, preventing it from overheating in hunting use.
  • a projectile is obtained that expands when it hits the target, as it has a spherical element placed at the end of the conical area of greater hardness and toughness than the rest of the projectile and has a perforation that goes from the tip of the conical area to the base of the conical area.
  • the projectile also benefits from increased aerodynamics, due to the material used in the manufacture of the spherical element, as its melting temperature is much higher than that of the plastic polymers currently used, ensuring that it arrives at the impact of the target in one piece, and finally a projectile that avoids degrading the environment as it is free of plastics and lead is achieved.
  • Figure 1 shows that the monolithic expanding projectile object of the invention comprises a cylindrical body (1) which at one end thereof continues with a continuously decreasing diameter, configuring a conical area (2), which has a perforation (4) that goes from the tip of the conical area (2) to the end of the conical body (1) with which it connects, joining a spherical element (3) at the end of the conical area (2) and at the mouth of access to the interior of the opening (4).
  • the cylindrical body (1) and the conical area (2) are solid, except for the perforation (4) of the conical area (2), using material preferably but not limited to copper, while the spherical element (3) is made of a material of a higher hardness than the material used in the manufacture of the cylindrical body (1) and the conical area (2).
  • the spherical element which is always of lower hardness and toughness than the barrel of the gun, may be made of, for example, steel.
  • annular grooves (6) On the cylindrical body, as can be seen in Figure 1 , there is a series of annular grooves (6) separated from each other, defining annular protrusions (6), also separated from each other.
  • This alternating arrangement of protrusions (5) and grooves (6) has a lubricating function by reducing friction between the projectile and the barrel tube and consequently reducing overheating and overpressure in the barrel.
  • the number of protrusions (5) is four.
