Title:
LASER HEAD WITH AXIAL CRASH PROTECTION
Document Type and Number:
WIPO Patent Application WO/2011/038254
Kind Code:
A3
Abstract:
An upper housing assembly includes a pivot arm having an upper cam surface adjacent a distal end. A cam follower is coupled to a laser head to move up and down with a laser head. The cam follower exerts a downward force on the upper cam surface during normal operation. Thus, as the pivot arm rotates back and forth, the laser head moves up and down. A assist gas hose can be coupled between the upper housing and the laser head which has a spiral configuration permitting relative axial movement between the upper housing and the laser head. Upon an upward axial force being exerted on the laser head, the cam follower moves upwardly away from the upper cam surface.
