Abstract
A laser aiming device having a plasma tube encased by a cylindrical member upon which windage and elevation adjustments act. Resilient ring members separate the cylindrical member from the plasma tube. Another resilient member located between the cylindrical member and an outer housing member cavity wall provides counterforces against which the windage and elevation adjustments act.
Claims13
A laser aiming device for firearms comprising:
- a housing member having a cavity adapted to receive a laser plasma tube;
- a laser plasma tube positioned within said cavity;
- a cylindrical member positioned within said cavity so as to surround said plasma tube about a longitudinal axis;
- and
- resilient means separating said cylindrical member and said plasma tube to cushion the plasma tube from shock forces generated by the firearm with which it is utilized;
- wherein said cylindrical member includes interconnecting cylindrical sleeve portions, one of which can be partially inserted into one end of the other.

A laser aiming device for firearms comprising:
- a housing member having a cavity adapted to receive a laser plasma tube;
- a laser plasma tube positioned within said cavity;
- a cylindrical member positioned within said cavity so as to surround said plasma tube about a longitudinal axis;
- and
- resilient means separating said cylindrical member and said plasma tube to cushion the plasma tube from shock forces generated by the firearm with which it is utilized;
- further including resilient plasma tube support means positioned at opposite ends of said plasma tube and in contact therewith to support said plasma tube and separate said plasma tube from walls of said cavity;
- further including means for adjusting the axis of the plasma tube relative to the housing member, said means operatively engaging said housing member and one end of said cylindrical member, said cylindrical member pivoting about its other end.

A laser aiming device, comprising:
- a housing member having a cavity adapted to receive a laser plasma tube;
- a laser plasma tube positioned within said cavity;
- a cylindrical member positioned within said cavity so as to surround said plasma tube about a longitudinal axis thereof;
- a number of resilient rings positioned about a central portion of said plasma tube and separating said cylindrical member and said plasma tube with a cushioned support;
- a pair of resilient ring members positioned at opposite ends of said plasma tube supporting said plasma tube within said cavity;
- a number of adjusting screws operatively engaged with said housing member and one end of said cylindrical member, rotation of said screws causing said cylindrical member to pivot about its other end and, consequently, causing said longitudinal axis of said plasma tube to be realigned;
- and
- a resilient member positioned between said cylindrical member and a wall of said cavity, said resilient member providing counterforces against which said adjusting screws act.

A laser aiming device, comprising:
- a housing member having a cavity adapted to receive a laser plasma tube;
- a laser plasma tube positioned within said cavity;
- a cylindrical member positioned within said cavity so as to surround said plasma tube about a longitudinal axis thereof, said cylindrical member comprising two sections operatively engaged to each other, one of said sections of said cylindrical member including a tubular tapered portion and said other of said sections including a non-tapered tubular portion adapted to receive said tubular tapered portion;
- a number of resilient rings positioned about a central portion of said plasma tube and separating aid cylindrical member and said plasma tube with a cushion support;
- a pair of resilient ring members positioned at opposite ends of said plasma tube supporting said plasma tube within said cavity;
- a number of adjusting screws operatively engaged with said housing and one end of said cylindrical member, rotation of said screws causing said cylindrical member to pivot about its other end, and consequently, causing said longitudinal axis of said plasma tube to be realigned, and
- a resilient member positioned between said cylindrical member and a wall of said cavity, said resilient member providing counter forces against which said adjusting screws act.
