Abstract
An angle measurement and distance demarcation device has a body having a first surface, an axis which extends from the first surface, and a containing room. The device also has a rotating unit coupled for rotation about the axis, and a laser emitter. The device further includes a coupling mechanism provided around the axis and coupling the rotating unit to the body, and a power supply unit provided inside the containing room and coupled to the laser emitter for supplying power to laser emitter. The device can be used together with either a triangular angle gauge or a disk angle gauge.
Claims21
An angle measurement and distance demarcation device, comprising:
- a body having a first surface, an axis which extends from the first surface, and a containing room;
- a rotating unit coupled for rotation about the axis, the rotating unit having a laser emitter;
- a magnet positioned on the first surface for attracting the rotating unit to the body;
- and
- a power supply unit provided inside the containing room and coupled to the laser emitter for supplying power to the laser emitter.
An angle measurement and distance demarcation device, comprising:
- a body having a first surface, an axis which extends from the first surface, and a containing room;
- a rotating unit coupled for rotation about the axis, the rotating unit having a laser emitter;
- means provided around the Axis for 1 the rotating unit to the body;
- and
- a power supply unit provided inside the containing room and coupled to the laser emitter for supplying power to the laser emitter;
- wherein the means includes a shaft extending from the first surface of the body along the axis, a magnet that attracts the rotating unit to the body, and a C-shaped ring that secures the shaft to the rotating unit.
An angle measurement and distance demarcation system, comprising:
- (a) a first gauge, comprising:
- a body having a first surface, and an axis which extends from the first surface;
- a rotating unit coupled for rotation about the axis, the rotating unit having a laser emitter;
- means provided around the axis for coupling the rotating unit to the body;
- and
- a fillister having a longitudinal groove and a first side surface that is 1 the axis;
- and
- (b) a second gauge having a triangular configuration, a planar surface and a side rim that extends perpendicular to the planar surface, wherein only the side rim of the second gauge is removably retained inside the longitudinal groove of the fillister.
An angle measurement and distance demarcation system, comprising:
- (a) a first gauge, comprising:
- a body having a top surface, a bottom surface, and an axis which extends from the top surface;
- a rotating unit coupled for rotation about the axis, the rotating unit having a laser emitter;
- means provided around the axis for coupling the rotating unit to the body;
- and
- a fillister having a side wall surface that is parallel to the axis;
- (b) a second gauge having a top surface, and a side edge that is positioned against the side wall surface of the fillister;
- and
- means for removably coupling the bottom surface of the body to the top surface of the second gauge.
