A laser unit for providing at least one of a laser level line and a laser plumb line, where the unit includes both a locked mode and an unlocked (or auto-leveling) mode. In the unlocked mode, the laser unit is configured to provide at least one of a level line or a plumb line when the pendulum assembly is free to settle to a point of equilibrium. In the locked mode, a pendulum locking mechanism locks the laser assembly into a fixed position regardless of the orientation of the laser unit. Optionally, an attachment accessory may also be provided. The attachment accessory preferably includes a ball and socket joint attachment assembly that is configured for attaching the laser unit to the attachment accessory such that the laser unit can be rotated or tilted with respect to the attachment accessory.

What is claimed is: 1. A laser unit for providing at least one of a laser level line and a laser plumb line, the laser unit comprising: a housing; a pendulum assembly located within said housing; a laser assembly for providing either a level line or a plumb line, said laser assembly being mounted upon said pendulum assembly such that said laser unit is configured to provide at least one of a level line or a plumb line when said pendulum assembly is in a unlocked mode; and a pendulum locking mechanism for locking said laser assembly into a locked mode in which said laser assembly is locked into a fixed position regardless of the orientation of said laser unit; wherein said pendulum assembly includes: a pendulum bearing that is pivotably attached to a pendulum bearing support assembly; and a pendulum bob mounted below said pendulum bearing; wherein said pendulum locking mechanism includes: a pendulum lock drive arm that includes a pair of L-shaped slots; and a pair of pivotable pendulum locks that each include a pin configured to mate with one of said L-shaped slots. 2. The laser unit as defined in claim 1, further comprising a second laser assembly, wherein one of said laser assemblies provides a level line and the other of said laser assemblies provided a plumb line, and further wherein said pendulum locking mechanism locks both of said laser assemblies in a fixed position. 3. The laser unit as defined in claim 2, wherein said level line laser assembly provides a laser line with a fan angle of approximately 120��; and said plumb line laser assembly provided a laser line with a fan angle of approximately 140��. 4. An attachment accessory for a laser unit, the attachment accessory comprising: a main body; and a ball and socket joint attachment assembly attached to said main body, said ball and socket joint attachment assembly configured for attaching a laser unit to said attachment accessory such that the laser unit can be rotated or tilted with respect to said attachment accessory; a pair of stabilizing legs configured and arranged to swing out from said main body; and wherein each of said stabilizing legs is pivotably attached to said main body, and further wherein when said stabilizing legs are pivoted outwards from said main body from a closed position, in which a bottom end surface of each of said stabilizing legs is approximately flush with a bottom surface of said main body, into an open position, said stabilizing legs each swivel slightly downwards such that the bottom end surface of each of said stabilizing legs is slightly separated from a plane coincident with the bottom surface of said main body. 5. The attachment accessory according to claim 4, wherein said ball and socket joint attachment assembly includes: a shaft that includes a threaded portion on a first end and a ball portion on a second end; and a socket for receiving said ball portion, wherein said ball portion and said socket are configured and arranged to permit both 360�� rotation of said ball portion within said socket and tilting of said shaft with respect to said main body of up to approximately 45��. 6. The attachment accessory as defined in claim 4, wherein said ball and socket joint attachment assembly includes: a shaft that includes a threaded portion on a first end and a ball portion on a second end; and a socket for receiving said ball portion, wherein said socket includes a collar that permits said shaft to be tilted to a first angle and further wherein said collar includes a slotted portion that permits said shaft to be tilted to a second angle, where said second angle is greater than said first angle. 7. The attachment accessory as defined in claim 4, wherein said ball and socket joint attachment assembly includes: a shaft that includes a threaded portion on a first end and a ball portion on a second end; and a socket for receiving said ball portion, wherein said socket includes a locking ring for locking said ball and socket joint attachment assembly into a fixed position with respect to said main body. 8. The attachment accessory as defined in claim 7, wherein: said locking ring includes an internally threaded portion; and said main body includes an externally threaded portion configured and arranged to mate with said internally threaded portion of said locking ring. 9. The attachment accessory as defined in claim 4, wherein said main body includes at least one internally threaded tripod mounting aperture for receiving an externally threaded tripod shaft. 10. The attachment accessory as defined in claim 4, wherein said main body further comprises: at least one strap raceway that extends completely through said main body; and at least one channel that extends along an outer surface of said main body for facilitating alignment of said attachment accessory with respect to a cylindrical object. 11. The attachment accessory as defined in claim 4, further comprising at least one magnet that creates a magnetic field near at least one outer surface of said main body, wherein said at least one magnetic is configured and arranged for affixing the attachment accessory to an object containing a magnetic material. 12. The attachment accessory as defined in claim 4, further comprising a reference plate pivotably attached to said main body, wherein said reference plate is configured and arranged to be pivoted between a rest position in which said reference plate extends generally horizontally and a supporting position in which said reference plate extends generally vertically. 13. The attachment accessory as defined in claim 4, wherein said stabilizing legs are each pivotably attached to said main body via a pivot axis that is inclined slightly outwardly, with respect to a vertical line, and further wherein the bottom surface of the main body extends horizontally. 14. A system for providing a laser line on a surface, the system comprising: a laser unit for providing at least one of a laser level line and a laser plumb line; and an attachment accessory for said laser unit, wherein said attachment accessory includes: a main body; and a ball and socket joint attachment assembly attached to said main body, said ball and socket joint attachment assembly configured for attaching said laser unit to said attachment accessory such that said laser unit can be rotated or tilted with respect to said attachment accessory, wherein a socket of said ball and socket joint attachment assembly includes an upper flange portion and a lower flange portion, and further wherein said main body includes an annular shoulder which acts upwardly against said upper flange portion, and an upper inner surface, which acts downwardly against said lower flange, such that said socket is maintained in association with said main body. 15. The system as defined in claim 14, wherein said laser unit includes: a housing; a pendulum assembly located within said housing; a laser assembly for providing either a level line or a plumb line, said laser assembly being mounted upon said pendulum assembly such that said laser unit is configured to provide at least one of a level line or a plumb line when said pendulum assembly is in a unlocked mode; and a pendulum locking mechanism for locking said laser assembly into a locked mode in which said laser assembly is locked into a fixed position regardless of the orientation of said laser unit. 16. The system as defined in claim 14, wherein said attachment accessory further includes: a pair of stabilizing legs configured and arranged to swing out from said main body, wherein each of said stabilizing legs is pivotably attached to said main body via a pivot axis that is inclined slightly outwardly, with respect to a vertical line, whereby a bottom end surface of each of said stabilizing legs each moves slightly downwardly when said stabilizing legs are pivoted outwards from said main body into an open position.
