US12339079 - Firearm

The patent describes a firearm featuring a safety mechanism that utilizes a radioluminescent marking to indicate its safety state through visible light emission. This marking, which is activated or concealed by a movable part of the firearm, enhances safety by providing a clear visual cue of whether the firearm is in a safe or ready-to-fire condition.

Claim 1

1. A firearm comprising: a firearm safety for clearly indicating a safety state of the firearm by a perceptibility and a non-perceptibility of a light transmission of the firearm safety, the firearm safety having: a movable part attached to the firearm; and an optically perceptible safety marking provided in a recess on a housing, on a housing system, or on a bolt of the firearm for clearly indicating a safe state of the safety state of the firearm; wherein the safety marking is radioluminescent and has a tritium gas light source provided in a binding agent, and is fastened to the firearm in the recess by an adhesive; and wherein, depending on a position of the movable part, the safety marking is optically uncovered or covered, such that when the firearm is in the safe state the safety marking is optically uncovered and the light emission of the firearm safety is optically perceptible, and when the firearm is in a ready-to-fire state the safety marking is optically covered and the light emission of the firearm safety is not optically perceptible, such that the safe state of the firearm is unmistakably indicated by the optically perceptible light output of the tritium gas light source. a firearm safety for clearly indicating a safety state of the firearm by a perceptibility and a non-perceptibility of a light transmission of the firearm safety, the firearm safety having: a movable part attached to the firearm; and an optically perceptible safety marking provided in a recess on a housing, on a housing system, or on a bolt of the firearm for clearly indicating a safe state of the safety state of the firearm; wherein the safety marking is radioluminescent and has a tritium gas light source provided in a binding agent, and is fastened to the firearm in the recess by an adhesive; and wherein, depending on a position of the movable part, the safety marking is optically uncovered or covered, such that when the firearm is in the safe state the safety marking is optically uncovered and the light emission of the firearm safety is optically perceptible, and when the firearm is in a ready-to-fire state the safety marking is optically covered and the light emission of the firearm safety is not optically perceptible, such that the safe state of the firearm is unmistakably indicated by the optically perceptible light output of the tritium gas light source.
