Abstract
Abstract A novel apparatus for establishing a reference plane or a line comprising a laser beam with means for rotating the beam to establish a plane and including a bracket mechanism which can be attached to the ceiling or a wall so as to support the laser mechanism so that it can be adjusted in a number of directions to allow its height, and its angular relationship to be set to any desired values.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
176 words
A laser holding and adjusting bracket for supporting a laser on a wall moulding at a desired orientation and height comprising, an angle member with one extension of the angle resting on and mating with a horizontal extension of the wall moulding, a pair of clamps releasably clamping said one extension to said horizontal extension, said angle member having its other extension thus held in a vertical orientation. a main frame member attachable to said other extension, a C-shaped member pivotally attached to said main frame member and pivotal about a first horizontal axis, a generally vertical laser supporting frame member pivotally attached to said C-shaped member on a second horizontal axis which is at right angles to said first horizontal axis, a means for adjusting said supporting frame about said first and second axis, a laser housing, an attachment member connected to said laser housing and adjustable attachment means connecting said attachment member to said generally vertical laser supporting frame member for vertical adjustment of said attachment member with respect to said supporting frame member.
Claim 2
Dependent Claim
176 words
A laser holding and adjusting bracket for supporting a laser on a wall moulding at a desired orientation and height comprising, an angle member with one extension of the angle resting on and mating with a horizontal extension of the wall moulding, a pair of clamps releasably clamping said one extension to said horizontal extension, said angle member having its other extension thus held in a vertical orientation. a main frame member attachable to said other extension, a C-shaped member pivotally attached to said main frame member and pivotal about a first horizontal axis, a generally vertical laser supporting frame member pivotally attached to said C-shaped member on a second horizontal axis which is at right angles to said first horizontal axis, a means for adjusting said supporting frame about said first and second axis, a laser housing, an attachment member connected to said laser housing and adjustable attachment means connecting said attachment member to said generally vertical laser supporting frame member for vertical adjustment of said attachment member with respect to said supporting frame member.
Claim 3
Dependent Claim
60 words
A laser holding and adjusting bracket according to claim 1 including first means for locking said vertical laser supporting frame member relative to said C-shaped member, and a first indicating level vial mounted on said laser housing to indicate when said housing and said vertical laser supporting frame members are in a vertical position relative to said second horizontal axis.
Claim 4
Dependent Claim
60 words
A laser holding and adjusting bracket according to claim 2 including second means for locking said vertical laser supporting frame member relative to said main frame member and a second indicating level vial mounted on said laser housing to indicate when said housing and said vertical laser supporting frame member are in vertical position relative to said first horizontal axis.
Claim 5
Dependent Claim
27 words
A laser holding and adjusting bracket according to claim 3 wherein said attachment member is linearly adjustable relative to said attachment means by rack and pinion means.
Claim 6
Dependent Claim
57 words
A laser holding and adjusting bracket according to claim 4 wherein said first means for adjusting comprises a first threaded shaft extending parallel to said first horizontal axis with one end threadedly connected to said main frame and the other end connected to said vertical laser supporting frame member at a point away from its pivot point.
Claim 7
Dependent Claim
28 words
A laser holding and adjusting bracket according to claim 5 including means for rotating said first threaded shaft and first locking means for locking said first threaded shaft.
Claim 8
Dependent Claim
49 words
A laser holding and adjusting bracket according to claim 4 wherein said second means for adjusting comprises a second threaded shaft extending parallel to said second horizontal axis with one end threadedly connected to said main frame and the other end connected to said vertical laser supporting frame member.
Claim 9
Dependent Claim
28 words
A laser holding and adjusting bracket according to claim 7 including means for rotating said second threaded shaft and second locking means for locking said second threaded shaft.
