US12698950 - Laser cartridge for dryfire training

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.

dryfiretraininglasercartridge

The patent describes a laser cartridge designed for dry fire training that fits into a firearm’s chamber and simulates shot placement by emitting a laser beam when the trigger is pulled. This device includes a housing that mimics an ammunition cartridge, a power supply, a PC board, and a laser, all working together to enhance training sessions.

Claim 1

1 . 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 ( 12 A) 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 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 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 ( 12 A) 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 ).
