Abstract:
A tubular, barrel-shaped laser pointer for generating varied optical effects comprising:a first metal barrel having first and second open end portions, said first open end portion having threads formed therein;a metal screw cap in threaded engagement with said first open end portion;a battery set mounted within said first metal barrel;a control circuit board mounted within said first metal barrel;a first spring member positioned within said first metal barrel, said first spring member elastically and electrically coupling said battery set to said control circuit board;a laser diode located within a second metal barrel;a second spring member elastically and electrically coupling said laser diode to said control circuit board;said second metal barrel having a first end portion wherein said first end portion threadedly engages said second open end portion of said first metal barrel and said second metal barrel displaces axially with respect to said first metal barrel upon rotation of said second metal barrel about said first metal barrel;a socket fixedly mounted within said first end portion of said second metal barrel, said socket in contact with said laser diode when said second metal barrel is in a first axial position, said second metal spring maintaining said contact between said socket and said laser diode, said laser diode being held in a substantially stable position with respect to said socket, said second metal barrel having a second axial position wherein said laser diode is displaced from said socket, said second metal spring for permitting displaceable and oscillatory motion of said laser diode within said second metal barrel when said laser pointer is displaced to create optical effects.
