Abstract
An adjustable platform in two orthogonal directions for the angular alignment of the axis of a solid state laser diode. The platform carries the laser diode at its center and is attached to a base plate at three points. Two attachment points are adjustable and provide for fine angular adjustments by changing the separation of the base plate and platform. The third attachment point provides for a fixed separation between base plate and platform and also preloads the tension on the adjustable attachments. The geometric relationship of the attachment points provides for the orthogonality and independence of the angular adjustments.
Claims51
A laser alignment apparatus for aligning an angle of a laser relative to a laser mount which attaches to a firearm, said laser alignment apparatus comprising:
- a laser element;
- a housing for the alignment apparatus;
- a base plate, coupled to said housing, having an inner opening with an annular configuration for allowing movement of said laser element within said base plate;
- a platform having an inner opening with an annular configuration substantially coextensive with the inner opening of said base plate and means for attaching said laser element to said platform;
- a spacer attachment means for holding said base plate and platform together and for facilitating relative spacing therebetween;
- and
- a first adjustment means and a second adjustment for adjusting said platform relative to said base plate, said spacer means is located in said base plate such that an angel between a line between said spacer means and said first adjustment means and a line between said spacer means and said second adjustment means is a right angle.
A laser alignment apparatus for aligning an angle of a laser relative to a laser mount which attaches the laser to a firearm, said laser alignment apparatus comprising:
- a laser element;
- a base plate coupled to the laser mount;
- a platform having said laser element attached;
- first adjustment means and second adjustment means for adjusting said platform relative to said base plate;
- said first adjustment means including a first threaded adjustment opening through said base plate, a first threaded adjustment opening through said platform, both of said first adjustment openings being aligned, and a first threaded adjustment screw;
- said second adjustment means includes a second threaded adjustment opening through said base plate, a second threaded adjustment opening through said platform, both of said second adjustment openings being aligned and a second threaded adjustment screw;
- and
- said first and second threaded adjustment openings through said base plate have a first thread pitch and said first and second threaded adjustment openings through said platform have a second thread pitch, said first and second thread pitches being different.
A laser aiming apparatus for a firearm, comprising:
- a laser housing;
- a base plate disposed within and attached to the housing;
- a platform disposed within the housing adjacent the base plate;
- a lasing element attached to the platform;
- spacer means for retaining the platform adjacent the base plate;
- a first and second adjustment screw threadingly engaging the platform with first thread pitches and engaging the base plate with second thread pitches differing from said first pitches, wherein rotation of the first or second screw reorients the platform and lasing element with respect to the laser housing.
A laser aiming apparatus for a firearm, comprising:
- a base plate attached to an apparatus housing;
- a platform disposed adjacent the base plate;
- a lasing element coupled to the platform;
- pivoting means for facilitating relative pivoting between the platform and the base plate;
- first adjustment means for adjusting the orientation of the platform with respect to the base late along a first pivot axis;
- and
- second adjustment means for adjusting the orientation of the platform with respect to the base plate along a second pivot axis, said first and second adjustment means being located so that a line from said first adjustment means to said pivoting means is approximately perpendicular to a line from said second adjustment means to said pivoting means.
A laser aiming device for a firearm comprising:
- a device housing;
- a base plate coupled to the housing;
- a platform disposed adjacent the base plate;
- a lasing element coupled to the platform and
- first and second adjustment screws respectively threadingly engaging the base plate with a first thread pitch and the platform with a second thread pitch, wherein rotation of either the first or second adjustment screw alters an orientation of the platform with respect to the base plate.
A laser alignment apparatus for aligning a laser mounted to a fire arm comprising:
- an apparatus housing;
- a base plate coupled to the housing;
- a platform disposed adjacent the base plate;
- a lasing element coupled to the platform;
- spacer means for maintaining a relative spacing between the base plate and the platform;
- and
- first and second adjustment screws respectively engaging the platform with a first thread pitch and the base plate with a differing second thread pitch, said first and second adjustment screws being positioned so that a line from said first adjustment screw to said spacer means is at approximately right angle to a line from said second adjustment screw to said spacer means, wherein rotation of the first adjustment screw pivots the platform with respect to the base plate about a first axis and rotation of the second adjustment screw pivots the platform with respect to the base plate about a second axis.
A laser alignment apparatus for aligning an angle of a laser relative to a laser mount which attaches the laser to a reference, said laser alignment apparatus comprising:
- a lasing element;
- a housing for the laser element;
- a base plate, coupled to the housing, having an inner opening with an annular configuration for allowing movement of said laser element within said base plate;
- a platform having an inner opening with an annular configuration substantially coextensive with the inner opening of said base plate and means for attaching said laser element to said platform;
- a spacer means for facilitating relative pivoting between said base plate and platform, including a threaded screw and relative spacer openings through said base plate and said platform, both said spacer openings being aligned and threaded to accommodate said threaded screw;
- a first adjustment means and a second adjustment means for adjusting said platform relative to said base plate.
A laser alignment apparatus for aligning an angle of a laser relative to a laser mount which attaches a laser to a firearm, said laser alignment apparatus comprising:
