Abstract

A laser positioning device is provided in which a level is associated with a demountable mounting set-up and a plate member. The plate member projects laterally from the level and is scribed with a protractor. A pointer is pivotally associated with the apex of the protractor. A laser beam generator is associated with the pointer. Thus, a laser beam from this generator can be impinged against a remote target location that is in a predetermined orientation relative to the generator when the device is mounted by the mounting set-up.

Dependent claims

A laser positioning device comprising:

(a) a level means comprising an elongated, rigid, body means that is cross-sectionally generally rectangular in profile, and that has a pair of opposed side faces and a pair of opposed edge faces, said body means holding at successive respective longitudinal locations along said body means individual members of a plurality of bubble-type position identification means which are each viewable from a least one of said side faces for positioning said level means in a predetermined orientation;
(b) non-destructive, demountable mounting means connected to said level means for mounting said device upon a surface, said mounting means including a pair of mounting members which are positioned on the other one of said side faces in longitudinally spaced relationship to one another relative to said level means, and said mounting means including first association means for so connecting said mounting means with said level means;
(c) a plate member that has an edge portion which is connected to one of said edge faces, and a generally opposed edge portion that projects laterally outwardly and perpendicularly from said one edge face beyond said one side face, and that has scribed on the outside face thereof a protractor whose apex is generally in perpendicular, laterally outwardly spaced relationship relative to said one side face, and said plate member including second association means for so connecting said plate member with said one edge face;
(d) an elongated, rigid pointer means with pivot means pivotally mounting and adjustable clamping said pointer means on said outside face at a pivot axis for arcuate movements, said pivot axis being centered at said apex, said pointer means having locating means for positioning said pointer means relative to said protractor at a selectable angle and said pointer means having an outwardly extending terminal end portion located opposite said locating means;
and
(e) laser beam generating means connected with said terminal end portion, said beam generating means including on/off switch means for actuating said beam generating means, so that, when so actuated, a laser beam can be projected outwardly from said beam generating means perpendicular to said pivot axis, and said beam generating means including third association means for so connecting said beam generating means with said terminal end portion;
whereby a laser beam from said beam generating means can be impinged against a remote target that is in a predetermined angular orientation relative to said level means when said device is so mounted.
