Abstract
Various laser level designs are shown. In one example, a laser level includes a rotating laser projection assembly to allow users to adjust the placement of the discontinuity in the projected laser plane. In another example, the laser level includes a lanyard attachment robust enough to support the weight of the laser level. The lanyard attachment includes a plurality of prongs that enhance the coupling to the housing of the device.
Claims20
A laser level comprising:
- a housing;
- a laser generator positioned within the housing and emitting a laser projection;
- and
- a rotating laser projection assembly coupled to the housing, the rotating laser projection assembly comprising:
- a base;
- and
- a cage rigidly coupled to the base, wherein the base is rotatably coupled to the housing such that the cage is rotatable about a first axis, the cage comprising:
- a plurality of legs;
- and
- a plurality of windows at least partially defined by the plurality of legs;
- wherein the laser projection is projected through at least one of the plurality of windows;
- and
- wherein the cage is rotatable about the first axis between a first position in which one of the plurality of legs creates a first discontinuity in the laser projection and a second position in which the one of the plurality of legs creates a second discontinuity in the laser projection such that a location of the first discontinuity is different than a location of the second discontinuity.
