1. A laser level, comprising:
- a housing;
a laser generator assembly housed in the housing and generating a laser beam,a projector configured to project the beam from the laser generator outside of the housing onto a target surface;
wherein the laser is a rotary laser and the projector rotates to rotate projection of the beam;
the laser level further comprising at least one protective leg extending from the housing, the protective leg blocking projection of the beam along part of its path as the projector rotates;
wherein a width of the beam is at least 20% greater than a width of the at least one protective leg where the beam contacts the at least one protective leg.

Abstract
A laser level including a housing. A laser generator assembly is housed in the housing and generates a laser beam. A projector projects the beam from the laser generator outside of the housing onto a target surface. The laser is a rotary laser and the projector rotates to rotate projection of the beam. The laser level also includes protective arms extending from the housing, the protective arms blocking projection of the beam along part of its path as the projector rotates. A width of the beam is at least twenty percent greater than a width of the leg where the beam contacts the leg.

11. A laser level, comprising:
-
a housing; a laser generator assembly housed in the housing and generating a laser beam; a projector configured to project the beam from the laser generator outside of the housing; a motor, the motor connected to the projector and selectively driving the projector in a rotary motion whereby the beam is rotated; protective legs which protect the projector and are situated between the projector and a target surface along part of a path of the beam as the projector is rotated; wherein a width of the beam is at least 25% greater than a width of the leg where the beam contacts the leg; and wherein the width of the leg where the beam contacts the leg is at least 3 mm. - View Dependent Claims (12, 13, 14, 15)

16. A laser level, comprising:
-
a housing; a laser generator assembly housed in the housing and generating a laser beam; a projector configured to project the beam from the laser generator outside of the housing; a motor, the motor connected to the projector and selectively driving the projector in a rotary motion whereby the beam is rotated; protective legs which protect the projector and are situated between the projector and a target surface along part of a path of the beam as the projector is rotated; wherein the laser beam has a perpendicular cross section which is a cross section taken perpendicular to an axis of the laser beam, the perpendicular cross section having a first dimension and a second dimension perpendicular to the first dimension, the first dimension of the cross section being at least 20% larger than the second dimension. - View Dependent Claims (17, 18, 19, 20)
