Appliance specific laser aiming device

摘要

An appliance specific laser aiming device for visual spray pattern testing of fire suppression spray nozzles has a hollow cylindrical body with a first end threadably fitted to an adapter that is fitted to the existing spray nozzle. A laser module within the cylindrical body projects a light beam through the interior and out of the lens on the second end. The second end has dial adjustment. A hollow housing with grip removably and rotatably fits to proximal the first end. Rotating the hollow housing positions a chosen nozzle depiction for setting to match specific spray nozzle characteristics wherein one device tests a plurality of nozzles, including those of various manufacturers.

主权项

1. An appliance specific laser aiming device comprising:
a cylindrical member having a first end and a second end spaced apart from the first end; a threaded section disposed at the first end; a shoulder attached to the threaded section distal the first end; a bevel disposed atop the shoulder; a hollow sleeve disposed atop the bevel; an energy compartment disposed within the sleeve; an energy source removably disposed within the energy compartment; an exteriorly accessible on/off button disposed within the sleeve, the on/off button in operational communication with the energy compartment; a laser module in operational communication with the on/off button and the energy compartment; wherein a laser light is configured to issue centrally upward from the sleeve with an on position of the on/off switch; a reference indicator disposed on an exterior of the sleeve; a grip ring removably and rotatably disposed at least partially atop the sleeve; a dial housing affixed to the grip ring and extended to the second end; a plurality of nozzle depictions disposed within a perimeter of the second end; a plurality of dial notches, one dial notch of the plurality of dial notches disposed below each nozzle depiction of the plurality of nozzle depictions; a disc disposed within the plurality of nozzle depictions; a lens disposed within the disc; a gear drive system disposed within the dial housing, the gear drive system comprising:
a drive gear disposed within an inner perimeter of the dial housing;a vertically disposed axle affixed to the sleeve, the axle offset from a centerline of the cylindrical member;a slave gear disposed horizontally and rotatably on the axle, the slave gear in operational communication with the drive gear; anda filter wheel disposed on the slave gear, the filter wheel having a plurality of sequentially disposed light filters, one light filter of the plurality of light filters matching one nozzle depiction of the plurality of nozzle depictions; wherein a rotation of the dial housing is configured to align one dial notch of the plurality of dial notches with the reference indicator; wherein one dial notch of the plurality of dial notches is configured to position one light filter of the plurality of light filters centrally within the dial housing; and wherein the laser light is configured to pass through one light filter of the plurality of light filters and issue through the lens.
