Abstract
Abstract A laser beam generating module is disposed at or near the butt end of a handgun in substantial alignment with the gun barrel. The module may optionally include means for activating the laser which are responsive to the horizontal or vertical attitude of the handgun, means for adjusting the aiming module for accuracy at various ranges, and means for suppressing the laser beam until the user of the handgun is ready to use it. A version of the invention places the laser module at the end of a magazine insertable into the handgrip of an automatic handgun so that the laser module is carried just adjacent the butt end of the handgun. Placement of the laser module at the butt end of the weapon yields accuracy adequate for routine police work, does not upset the balance and feel of the weapon, and it enables the weapon to be carried by its user in its conventional holster. Variations of the invention are described such that the laser module is built into the handgrip of the weapon, inserted when attached to a conventional ammunition clip, and attached to the butt end of the weapon by means of a mounting bracket.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A laser-aimed weapons system, comprising a handgun having a barrel aligned along a longitudinal axis, a handgrip connected to said barrel and including a proximal portion of said handgrip adjacent said barrel, and a distal portion of said handgrip, and a small, lightweight, diode-type laser transmitter disposed within said distal portion of said handgrip, said small, lightweight, diode-type laser transmitter aligned for projecting a laser beam at an angle to said axis of said barrel, said angle being chosen to cause a beam from said laser to intersect said longitudinal axis of said barrel at a distance in the front of said handgun in the range of ten feet to infinity.
Claim 2
Dependent Claim
111 words
A laser-aimed weapons system, comprising a handgun having a barrel aligned along a longitudinal axis, a handgrip connected to said barrel and including a proximal portion of said handgrip adjacent said barrel, and a distal portion of said handgrip, and a small, lightweight, diode-type laser transmitter disposed within said distal portion of said handgrip, said small, lightweight, diode-type laser transmitter aligned for projecting a laser beam at an angle to said axis of said barrel, said angle being chosen to cause a beam from said laser to intersect said longitudinal axis of said barrel at a distance in the front of said handgun in the range of ten feet to infinity.
Claim 3
Dependent Claim
62 words
A laser sighting attachment for a handgun having a barrel and a handgrip including a butt end, comprising housing means, including means for disposing said attachment adjacent said butt end of said handgrip, and laser diode means within said housing means for generating a laser beam oriented to a course substantially parallel with a longitudinal axis of said barrel of said handgun.
Claim 4
Dependent Claim
62 words
A laser sighting attachment for a handgun having a barrel and a handgrip including a butt end, comprising housing means, including means for disposing said attachment adjacent said butt end of said handgrip, and laser diode means within said housing means for generating a laser beam oriented to a course substantially parallel with a longitudinal axis of said barrel of said handgun.
Claim 5
Dependent Claim
35 words
The laser sighting attachment of claim 2 wherein said means for disposing said attachment adjacent said butt end of said handgrip includes means for affixing said housing directly to said butt end of said handgrip.
Claim 6
Dependent Claim
28 words
The laser sighting attachment of claim 2 wherein said means for disposing said attachment adjacent said butt end of said handgrip includes means mountably insertable within said handgrip.
Claim 7
Dependent Claim
111 words
A small, lightweight, diode-type laser sighting device for a handgun having a handgrip having a butt end, comprising: means for attaching said laser sighting device at said butt end of said handgun in alignment with a longitudinal axis of a barrel of said handgun, and circuit means comprising: a power source, diode-type laser generating means including beam directing means for aligning a beam from said diode-type laser generating means in the direction of said longitudinal axis of said barrel of said handgun, and switch means responsive to verticality of said longitudinal axis of said barrel of said handgun for activating said laser generating means to generate a beam from said laser.
Claim 8
Dependent Claim
111 words
A small, lightweight, diode-type laser sighting device for a handgun having a handgrip having a butt end, comprising: means for attaching said laser sighting device at said butt end of said handgun in alignment with a longitudinal axis of a barrel of said handgun, and circuit means comprising: a power source, diode-type laser generating means including beam directing means for aligning a beam from said diode-type laser generating means in the direction of said longitudinal axis of said barrel of said handgun, and switch means responsive to verticality of said longitudinal axis of said barrel of said handgun for activating said laser generating means to generate a beam from said laser.
Claim 9
Dependent Claim
122 words
A laser-aimed weapons system comprising: A handgun having a barrel and a handgrip, each of said barrel and said handgrip having a longitudinal axis and said axes intersecting to define a plane of said handgun, said handgun being configured to propel a bullet when said handgun is discharged in a substantially vertical plane of said handgun, with said barrel of said handgun substantially level, along a predetermined trajectory through said plane of said handgun, said handgrip including a butt end positioned distant from said barrel and having small, lightweight, diode-type laser generating means disposed at said butt end, said small, lightweight, diode-type laser generating means aligned relative to said predetermined bullet trajectory to project a laser beam to intersect said bullet trajectory.
Claim 10
Dependent Claim
