Patent ID: 7069661

Claim:
A laser leveling device comprising: a housing, a laser instrument disposed in said housing for generating light, a switch disposed in said housing, a plate slidably received in said housing and movable relative to said housing including an aperture formed therein and movable to be selectively aligned with said laser instrument when said plate is moved relative to said housing to allow the light generated by said laser instrument to selectively emit through said aperture of said plate, and a lens attached to said plate, said lens including a first portion having a first pattern provided therein, said first pattern including at least one vertical line formed in said first portion of said lens to generate a first light beam when said laser instrument generates the light through said first portion of said lens, and including a second portion having a second pattern provided therein, said second pattern including at least one horizontal line formed in said second portion of said lens to generate a second light beam when said laser instrument generates the light through said second portion of said lens, said lens including an intermediate portion located between said first portion and said second portion of said lens, said plate being movable relative to said housing to selectively align either of said first portion or said second portion of said lens with said laser instrument, to allow the light beam generated by said laser instrument to selectively emit through either of said first portion or said second portion of said lens, said plate including a first actuator extended therefrom to selectively engage with said switch and to selectively actuate said laser instrument when said lens of said plate is aligned with said laser instrument, and including a second actuator extended therefrom to selectively engage with said switch and to selectively actuate said laser instrument when said aperture of said plate is aligned with said laser instrument.
