Abstract
This is a cartridge shaped laser dry fire training device that can be inserted into the chamber of a firearm and used for demonstrating where the simulated shots strike during each trigger press of a dry fire practice session when coupled with the DryFireMag training device as disclosed in U.S. Pat. No. 9,182,189 B2. The laser dry fire training device preferably is composed of a red diode laser, a set of batteries, and electronic PC board, a lens to allow the infrared light emitted by the diode mounted on a specially designed dry fire training magazine to excite the electronics of the electronic PC board, and two threaded cylinders to house said components.
Claims18
A laser cartridge (10) for dryfire training with a firearm (11) that has an EMR source (66) that is actuated responsive to a trigger of the firearm (11) being pulled by a user/shooter, and wherein actuation of the EMOR source (66) passes EMR into a chamber (13) defined in the firearm (11), the laser cartridge (10) comprising:
- a housing (16) that is configured as an ammunition cartridge and that is removably carried within the chamber (13) of the firearm (11), the housing (16) comprising:
- a first member (25) defining a medial channel (30);
- and
- a second member (40) that is releasably axially received in the medial channel (30) defined by the first member (25);
- and
- a PC board (39) carried within an electronics chamber (47) defined in the second member (40), the PC board (39) operatively communicating with a power supply (60) and with a laser (54);
- and
- the power supply (60) is releasably carried within a battery chamber (45) defined in the second member (40) and the power supply (60) supplies power to both the PC board (39) and to the laser (54);
- and
- the laser (54) is carried within a laser chamber (46) defined in the second member (40) and when the laser 54 is actuated responsive to receipt of a signal from the PC board (39), the laser (54) emits a laser beam/pulse (58) that is projected along a longitudinal axis (19) of the housing (16) and along a bore (12A) of a barrel (12) of the firearm (11);
- and
- an optical lens (65) carried at a first end portion (41) of the second member (40) of the housing (16) and operatively communicating with the PC board (39) to collect and focus EMR (59) emitted by the EMR source (66) onto the PC board (39) to cause the PC board (39) to generate the signal that is communicated to the laser (54) to actuate the laser (54) to emit the laser beam/pulse (58).
A laser cartridge (10) for dryfire training with a firearm (11) that has an EMR source (66) that is actuated responsive to a trigger of the firearm (11) being pulled by a user/shooter, and wherein actuation of the EMR source (66) passes EMR into a chamber (13) defined in the firearm (11), the laser cartridge (10) comprising:
- a housing (16) that is configured in the shape of an ammunition cartridge, and that is releasably carried within the chamber (13) defined in the firearm (11), the housing (16) comprising;
- a first cylindrical member (25) that has a first end portion (26), a second end portion (27), a longitudinal axis (28), an exterior surface (29), an O-ring groove (34) defined in the exterior surface (29) proximate the second end portion (27), a medial channel (30), an exterior diameter (33), an interior diameter (35), and threads (32) defined in an interior surface (31) of the medial channel (30);
- a second member (40) that is releasably axially received in the medial channel (30) defined by the first cylindrical member (25), the second member (40) having, a first end portion (41), a second end portion (42), a longitudinal axis (43), an exterior surface (44), a battery chamber (45), a laser chamber (46), an electronics chamber (47), threads (48) defined in the exterior surface (44) proximate the second end portion (42), and an extraction ring (49) proximate the first end portion (41);
- and
- a power supply (60) releasably carried within the battery chamber (45) defined in the second member (401, the power supply (60) having a circumferentially extending protective sheath (62) extending thereabout to insulate the power supply (60) from the housing (16) and wherein the power supply (60) operative communicates with a PC board (39) and with a diode laser (54) with circuitry (57);
- the diode laser (54) is carried within the laser chamber (46) defined in the second member (40), the diode laser (54) having a laser emitting end portion (55) and an electronics end portion (56), and the diode laser (54) when actuated, emits a laser beam/pulse (58) that is projected along a longitudinal axis (19) of the housing (16) and along a bore (12A) of the firearm (11) and outwardly from a muzzle (12B) of the firearm (11);
- and
- the PC board (39) is carried within the electronics chamber (47) defined in the second member (40), the PC board (39) operatively communicating with the diode laser (54) and with the power supply (60) generate, when actuated, a signal that is communicated to the diode laser (54) and which responsively causes the diode laser (54) to emit a laser beam/pulse that is projected along the longitudinal axis (19) of the housing (16) and along the bore (12A) of the firearm (11) and outwardly from the firearm muzzle (12B);
- and
- an optical lens (65) carried at the first end portion (41) of the second member (40) of the housing (16), the optical lens (65) operatively communicating with the electronic PC board (39) to collect and focus EMR (59) emitted from the EMR source (66) onto the PC board (39) to cause the PC board (39) to generate the signal that is communicated to the diode laser (54) to actuate the diode laser (54).
