Abstract
A level apparatus is disclosed that includes a body mounted on an elongate member. The body typically includes a laser that is capable of rotation about horizontal and/or vertical axes. The elongate member can be braced between, for example, a floor and a ceiling and the body is typically capable of longitudinal movement along an axis that is substantially parallel to a longitudinal axis of the elongate member. Movement of the body and other functions of the apparatus can be remote controlled.
Claims36
Apparatus for providing a reference point or line, the apparatus comprising a body connected to an elongate member having a longitudinal axis, the body having a laser and being capable of movement substantially parallel to the longitudinal axis of the elongate member, wherein the apparatus has a counterweight suspended from a plumb line, wherein the plumb line is attached at a first end thereof to the body, and at a second end thereof to the counterweight, the counterweight being used to adjust the orientation of the elongate member so that it is substantially vertical.
A method of providing a reference point or line for use in the construction industry, the method comprising the steps of:
- providing a body connected to an elongate member having a longitudinal axis, the body having a laser and being capable of movement substantially parallel to the longitudinal axis of the elongate member, wherein the body has a counterweight suspended therefrom by a plumb line;
- securing the elongate member in a substantially vertical orientation;
- adjusting the orientation of the elongate member so that it is plumb using the counterweight as a reference;
- positioning the laser at a pre-selected position on the elongated member;
- and actuating the laser.
