Grenade Patents (Class 102/482)
  • Patent number: 10066915
    Abstract: A multi-purpose munition operates in either a blast mode or a fragmentation mode according to a user input. When operating in the fragmentation mode, a fuze initiates a main explosive fill of the munition which in turn disperses fragments formed from a fragmentation layer of the munition. When operating in a blast mode, prior to initiating the main explosive fill, the fuze initiates a secondary energetic layer which discards the fragmentation layer. The fuze then initiates the main explosive fill thereby producing a blast effect.

  • Patent number: 7040236
    Abstract: Disclosed is an environmentally-friendly training hand grenade and a method of manufacturing the same. The training hand grenade is advantageous in that it is not necessary to recover fragments, generated by the explosion of the training hand grenade after use, because a bomb body of the training hand grenade is made of naturally degradable mineral matters, such as barite, tungsten, silica, and yellow earth, thereby many soldiers may be trained for a relatively short time using the training hand grenade. Furthermore, the training hand grenade is made of environmentally-friendly materials, and thus, its use is conducted without causing pollution. In addition, the training hand grenade is made of the mineral matters, thereby ensuring high explosiveness and explosive sound effect when the training hand grenade is exploded, and preventing soldiers from being injured by the fragments in use.

  • Patent number: 6968785
    Abstract: The locking and stabilizing device for grenades utilizes a solid nylon ring and multiple nylon ribbons that are attached to the ring at regular intervals around its circumference. During storage, the ring surrounds and locks the slider of the grenade in its storage position. But upon deployment, under aerodynamic forces the ring moves away from the slider, releasing the slider. When the slider is thusly released, it slides out and brings the detonator in place to be impacted upon by the pin when the grenade hits the target, thus detonating the grenade. The multiple ribbons extending from the ring unfurl due to the aerodynamic forces and provide stability to the grenade flight.

  • Patent number: 6761117
    Abstract: With typical ordnance systems, for example, grenades, a user must decide to explode the ordnance before the actual device is thrown. However, in many situations, it can be useful to be able to throw an ordnance system and make a decision to explode the device after it has landed. The present invention comprises a combined reconnaissance and ordnance device. The present invention is capable of real time acquisition of data, for example, digital still images, or video and audio data. The present invention also comprises a two way communications ability. By acquiring and then transmitting data to a remote console, the present invention allows a user to observe a given situation. After observing the environment surrounding the ordnance system, a user can determine whether or not to explode the ordnance system.
