Patent Images
1. A line generating device, comprising:
- a housing having a base;
a light generator mounted within the housing;
a first lens element mounted within the housing to receive light from the light generator and adapted to project at least a first fan-shaped beam of light outside the housing substantially within a first plane; and
a second lens element mounted within the housing to receive light from the-light generator and adapted to project a second fan-shaped beam of light outside the housing substantially within a second plane,wherein the first and second fan-shaped beams intersect outside of the housing and wherein the first and second planes are perpendicular to the base.

Abstract
A line generating device generates two fan-shaped beams of light at an angle to each other, and projects the beams onto an adjacent surface, where the beams are visible as lines on the surface. A user has access to the intersection of the lines, so that the intersection can be marked or otherwise used in combination with the lines, such as in aligning objects.

34. A line generating device, comprising:
-
a housing having a cutout portion and a base; at least one light generator; a first lens element mounted within the housing to receive light from the at least one light generator and adapted to project a first fan-shaped beam of light outside the housing substantially within a first plane; and a second lens element mounted within the housing to receive light from the at least one light generator and adapted to project a second fan-shaped beam of light outside the housing substantially within a second plane, wherein the first and second fan-shaped beams intersect outside of the housing at a line that is at least partially contained within a volume of space defined by the cutout portion of the housing. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 46, 47, 48)

49. A line generating device disposable on a surface, the line generating device comprising:
-
a housing; a light generator mounted within the housing; a first lens that receives light from the light generator and projects the light in a first fan-shaped beam substantially within a first plane; and a second lens that receives light from the light generator and projects the light in a second fan-shaped beam substantially within a second plane that intersects the first plane at an angle, wherein the first and second fan-shaped beams are projected outside the housing and intersect at an angle on the surface such that a user has access to an intersection point of the fan-shaped beams on the surface. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A line generating device comprising:
-
a housing; a light generator and a mirror mounted within the housing; a first lens that receives light from the light generator and projects the light in a fan-shaped beam substantially within a first plane; and a second lens that receives light from the mirror and the light generator and projects the light in a fan-shaped beam substantially within a second plane, wherein the fan-shaped beams are projected outside the housing and intersect at an angle on a surface, such that a user has access to an intersection point of the fan-shaped beams on the surface. - View Dependent Claims (60, 61, 62, 63)
