Description

  The present invention relates generally to non-igniting neutralized grenades, and more particularly to a self-standing grenade that can be controlled by a program and is reusable.

  A typical "flash van" grenade is a ignitable device that has a neutralizing element that is thrown near an adversary and emits a flashing bright flash or a loud popping sound. Use it to temporarily disable an adversary. In general, “flash van” grenades are used in high-risk situations, such as having to approach an armed adversary to take law enforcement action in a hostage situation.

  The danger of igniting grenades is that explosions can cause unintended damage to people and property, cause death, and can ignite and cause a fire. Firing grenades can cause serious injury or even kill a person. If the explosion is too early, it can hurt the user. Because of such dangers, the use of ignitable grenades is usually limited to the handling of full-time personnel in very high risk situations. Persons handling pyrotechnic grenades are often liable for damage or injury caused by the use of grenades.

  Several non-ignitable devices have been proposed so far. These non-ignitable devices have one or more drawbacks. Some are clunky and difficult to throw into where you want. Some are not designed to punch glass. Some cannot be reused. Some are easily damaged to prevent reuse. Some only emit light, others only emit sound. The effective light intensity and volume greatly vary depending on the rest position of the grenade. There are other non-ignitable devices that are not waterproof.

  Therefore, the risk of injury to the user and others and the chances of ignition and a fire are greatly reduced, and as a result, the need for neutralized grenades is eliminated so that the user is not liable for damage. Absent.

  A grenade designed to be thrown like a ball is desirable to reduce training time and increase throwing accuracy.

  A grenade that remains stable during throwing and easily punches glass is desirable.

  A grenade that can be programmatically controlled by the user to change the timing or output of the neutralization action of the grenade for different situations is desirable.

  A reusable grenade is desirable.

  It is more desirable to have a grenade that adjusts itself once it has landed so that the neutralization element can be used effectively and stably, and so that the emission of light and sound is maximized.

It is a bottom view, a front view, and a right side perspective view of a grenade. It is a bottom view of a grenade. It is a top view of a grenade. It is a front perspective view of the grenade held by the user's hand throwing armed. FIG. 8 is a longitudinal sectional view taken along line 8-8 in FIG. 2.

  Referring now to the drawings, FIG. 1 is a top, front, right side perspective view of an exemplary embodiment of a self-upstanding neutralizing grenade 10 of the present invention. FIG. 2 is a front view of the grenade 10. FIG. 3 is a rear view of the grenade 10. FIG. 4 is a bottom, front, right side perspective view of the grenade 10. FIG. 5 is a bottom view of the grenade 10. FIG. 6 is a top view of the grenade 10.

  The grenade 10 generally includes a top portion 22, a bottom portion 32, and a peripheral wall 12 therebetween. The upper portion, generally designated 20, includes a top portion 22. The lower portion generally indicated by reference numeral 30 includes a bottom portion 32. The peripheral wall 12 is curved upward and outward from the bottom portion 32, and the lower portion 30 is weighted so as to stand upright after the grenade 10 is thrown. The peripheral wall 12 may be convex between the bottom portion 32 and the top portion 22 so that the grenade 10 is more securely stopped in an upright posture. The peripheral wall 12 of the lower part 30 may be substantially hemispherical. When the grenade 10 lands after being thrown, it is preferable that the bottom portion 32 forms, for example, a flat horizontal surface 33 so that the vertical posture can be quickly taken without prolonged shaking. The weighted bottom portion 32 stabilizes the flying grenade 10 so that the grenade 10 can be thrown more accurately far away, and the bottom portion 32 takes the front position and punches out the window.

  The position of the sound hole 24 is preferably in the top portion 22 itself, but may be any other position on the peripheral wall 12, for example, any position on the upper portion 20. The sound hole 24 is an exit of the neutralizing sound generated in the grenade 10.

  In the illustrated embodiment, the control electronics 50 includes switch means 71, which includes a start switch such as a start button 72 and a programming switch such as a programming button 74. The buttons 72 and 74 are arranged in the back, so that the buttons 72 and 74 are not damaged, the grenade 10 rolls smoothly, and does not operate unexpectedly. With particular reference to FIGS. 4 and 5, the charging port 78 is disposed near the bottom 32 and accepts an external connection, such as a charger, to charge the battery for the control electronics 50. In the illustrated embodiment, the charging port 78 is a receiving port into which a male plug is inserted, and is covered with a divided cover 79 so that dust such as dust and dirt is not collected.

  Returning to another figure, the grenade 10 includes one or more neutralizing elements such as a sound source and a light source. A plurality of light sources, for example, LEDs 80 mounted on the drive circuit board 81 are disposed in the recess 86 of the peripheral wall 12 and covered with a transparent window 88 so as not to be damaged. As best seen in FIG. 6, in the exemplary embodiment, the three LEDs 80 have a number of irradiation fields from the grenade 10 to radiate the light collectively 360 degrees laterally about the vertical axis of the grenade 10. Positioned around grenade 10 at 120 degree intervals so that they overlap within inches. The longitudinal angle of the emitted light is preferably 100 degrees or more. Effective light output has been found to be in the range of 3000 lumens. Since the grenade 10 is urged toward the upright posture, all the light from the LED 80 shines outward, which is effective for neutralization.

  FIG. 7 is a front perspective view of the grenade 10 held by the user's hand 95 to be armed and thrown. The grenade 10 fits comfortably and securely in the user's hand 95 so that it can be thrown. The buttons 72 and 74 are arranged so that they can be operated with the thumb 96 of the user, and can be operated with the other hand (not shown).

  8 is a longitudinal sectional view taken along line 8-8 in FIG. The control electronic circuit 50 is housed in a casing (outer frame) generally indicated by reference numeral 40, and the casing 40 has a plurality of compartments including a bottom compartment 41, an intermediate compartment 42, an upper compartment 43, and a top compartment 44. Various seals such as an O-ring seal 46 and a cover seal 47 are sealed between the casing sections 41, 42, 43, and 44 to protect the control electronic circuit 50 from various liquids.

  When the grenade 10 is thrown, the bottom section 41 is formed so that the bottom section 41 becomes a leading element for punching a strong window, and when the grenade 10 is landed, the grenade bottom section 41 rolls downward and the grenade 10 stands upright. It is preferably made of a material such as thick, heavy steel with high strength. The other casing parts 42, 43, 44 may be made of a lightweight material such as plastic, for example high temperature polycarbonate. A plurality of powerful bolts 48 join the casing sections 41, 42, 43, 44 from top to bottom to complete the casing 40 and prevent damage to the casing 40.

  Another neutralization element is a destructive sound source such as a loudspeaker. For example, a piezoelectric speaker, a buzzer 65, and the like are arranged on the upper portion 20. The destructive sound generated by the buzzer 65 is, for example, a sound pressure of 110 dB and a frequency of 4 kHz. Sound exits the buzzer 65 through a hole 24 in the top 22. The grenade 10 may be urged to an upright posture, and the radiated sound is freely emitted from the top portion 22 and the maximum neutralizing sound is distributed throughout the room.

  A storage battery such as a rechargeable battery 60 is stored in the casing 40. Until now, rechargeable lithium ion batteries have been used. As shown in FIG. 4, the charging port 78 is electrically connected to the battery 60 and receives a power source to charge the battery 60.

  The control electronic circuit 50 is connected to the battery 60, the LED 80, and the buzzer 65 and controls their functions, and includes a main circuit board 51, an LED circuit board 81 for each LED 80, and a switching circuit board 76. The control electronics 50 preferably includes a microprocessor, as is well known in the art for controlling the mode of operation of the grenade 10. There may be a plurality of output modes of the LED 80 such as variable frequency and blinking in a fixed period.

  In one method of use, the output mode is set by pressing the programming button 74 in a certain sequence, the output mode being the first duration that the LED 80 blinks and the buzzer 65 rings intermittently, and the LED 80 and buzzer 65. And a second duration during which is turned off. This pattern is repeated until the grenade 10 is released from activation. When the user activates the control electronic circuit 50 by pressing the activation switch 72, a lamp behind the activation switch 72, for example, an activation switch lamp 73 such as an LED, is lit in green, for example. This lighting indicates that the grenade 10 is functioning. When the start switch 72 is pressed again in this state, the grenade 10 enters a neutralization mode in which the switch lamp 73 blinks. In the neutralization mode, after a predetermined or programmed short delay time giving the grace to throw the grenade 10, the pre-set first period LED 80 blinks intermittently and the buzzer 65 sounds intermittently and The set second period LED 80 and buzzer 65 are turned off. To cancel the neutralization mode of the grenade 10, the start switch 72 is pressed. If these steps are repeated, the grenade 10 can be used any number of times. The timing means is preferably used to allow the user to determine which outputs are turned on or off during all periods, for example by inputting with a programming button 74. Thus, the grenade 10 may be programmed to be optimal for various situations.

  It can be seen that the present invention effectively overcomes many of the disadvantages of the prior art. The grenade 10 is unlikely to harm the user or others. There is no possibility of ignition. As a result, the grenade 10 greatly reduces the situation attributed to the user.

  The grenade 10 is designed to be thrown like a ball with a user's hand 95. Therefore, the training time is minimal and the throwing position accuracy is improved. A powerful and weight-added lower part 30 stabilizes the grenade in the fly so that the grenade can be thrown more accurately and farther, and so that the bottom 32 faces forward and punches through the window. The grenade 10 can be programmed directly by the user so that the timing and output of the neutralization action of the grenade 10 can be changed to suit various situations. The grenade 10 can be reused.

  The grenade 10 adjusts its position by itself when landing so that the neutralizing action is effective and can be used stably.

  Although particular embodiments of the present invention have been described by way of example, the form, configuration, structure, and arrangement of parts described herein may be modified in various ways without sacrificing its advantages. Accordingly, all matters described herein are to be regarded as illustrative rather than restrictive, and all modifications within the spirit and scope of the invention are intended to be included within the scope of the appended claims. It is.
