Firearm laser sight alignment assembly
View Patent ↗A firearm laser sight alignment assembly includes a laser module for emitting a beam along an optical axis, the laser module having an outer seat. The alignment assembly encompasses a resilient grommet mechanically engaging the outer seat in a first adhesive free interference fit. The grommet includes an external seat sized to form adhesive free interferences fits with a laser cover and the housing, as the laser cover engages the housing to retain the grommet with respect to the housing and the laser cover. Upon operable assembly, the interference fits substantially preclude axial and longitudinal movement between the grommet and the laser module as well as the grommet and the laser cover and housing, while allowing angular movement of the laser module to a desired alignment position.
1. A laser sight for use with a firearm comprising:
a housing engageable to the firearm;
a resilient coupling joined to a laser, and;
a laser cover engaging the housing to retrain the resilient coupling with respect to the housing and the laser cover and forming an axial interference fit between the resilient coupling and at least one of the laser cover and the housing wherein the resilient coupling is positioned in a longitudinal interference fit between a first surface of a socket formed by the housing and the laser cover and a second surface of the socket that is longitudinally separated from the first surface of the socket.
2. The laser sight of claim 1 , wherein the resilient coupling has an uncompressed longitudinal length and the first surface and the second surface are separated at least in part by a longitudinal length that is less than the uncompressed longitudinal length of the resilient coupling.
3. The laser sight of claim 1 , wherein the socket has an axial dimension that is smaller than an axial dimension of an uncompressed resilient coupling mounted to the laser.
4. The laser sight of claim 1 , wherein the housing and laser cover are assembled using a stop indicating assembly of the housing and the laser cover such that any deviation from nominal sizes of the laser and resilient coupling does not vary the engagement of the laser cover and the housing.
5. A method for forming a laser sight for a firearm, the method comprising:
fitting a resilient coupling about a laser module;
engaging a laser cover with a housing to locate a portion of the laser module and the resilient coupling intermediate the laser cover and the housing; and
forming an axial interference fit between the resilient coupling and at least one of the laser cover and the housing wherein the resilient coupling is positioned in a longitudinal interference fit between a first surface of a socket formed by the housing and the laser cover and a second surface of the socket that is longitudinally separated from the first surface of the socket.
6. The method of claim 5 , wherein the resilient coupling has an uncompressed longitudinal length and the first surface and the second surface are separated at least in part by a longitudinal length that is less than the uncompressed longitudinal length of the resilient coupling and wherein the step of engaging a laser cover with a housing to locate a portion of the laser module and the resilient coupling intermediate the laser cover and the housing and forming an interference fit between the resilient coupling and at least one of the laser cover in the housing comprises compressing the resilient coupling along the longitudinal length thereof.
7. The method of claim 5 , wherein the socket is sized to form a portion of the axial interference fit with the coupling and a longitudinal interference fit with the coupling.
8. The method of claim 5 , wherein the socket has an axial dimension that is smaller than an axial dimension of an uncompressed resilient coupling mounted to the laser.
9. The method of claim 5 , wherein the housing and laser cover are assembled using a stop indicating assembly of the housing and the laser cover such that any deviation from nominal sizes of the laser and resilient coupling does not vary the engagement of the laser cover and the housing.
