Fire fighting monitor
View Patent ↗A fire-fighting monitor includes a body that has a fluid passageway and an inlet and an outlet. The inlet is adapted to mount to a base on a fire truck, and the body is configured so that the outlet is rotatable about a vertical axis over a 360 degree range of motion. In addition, the body is configured such that the outlet is rotatable about a horizontal axis over one range of motion of about 195 degrees in one form and about 270 degrees in another form.
1. A fire-fighting monitor comprising:
a body having a fluid passageway and forming an inlet and an outlet;
said inlet being adapted to mount to a base on a fire truck;
said body being configured so that said outlet is rotatable about a vertical axis over a 360 degree range of motion, and said body being configured so that in a first mounted orientation, said outlet is rotatable about a horizontal axis over one range of motion from about 180 degrees above horizontal to about 15 degrees below horizontal, and said body being configured so that, in a second mounted orientation, said outlet is rotatable about the horizontal axis over another range of motion from about 180 degrees below horizontal to about 90 degrees above horizontal, wherein:
said inlet comprising an inlet pipe section and being adapted to mount to the base on the fire truck, said body further comprising a first 180 degree elbow intermediate pipe section rotatably mounted to an outlet end of the inlet pipe section about the vertical axis, and a second 180 degree elbow outlet pipe section rotatably mounted to an outlet end of the intermediate pipe section about the horizontal axis, said second 180 degree elbow forming said outlet, and
said outlet pipe section having a larger radius of curvature than said intermediate pipe section wherein said outlet pipe section may rotate relative to said intermediate pipe section about the horizontal axis without interference from said intermediate pipe section.
2. The monitor according to claim 1 , further comprising a first driver for rotating said outlet about the vertical axis.
3. The monitor according to claim 2 , further comprising a second driver for rotating said outlet about the horizontal axis.
4. The monitor according to claim 1 , further comprising a driver for rotating said outlet pipe section about the horizontal axis.
5. The monitor according to claim 4 , wherein said outlet pipe section is sized to clear said driver when rotated about the horizontal axis.
6. The monitor according to claim 1 , wherein said monitor comprises a boom monitor.
7. The monitor according to claim 1 , wherein said monitor comprises a bumper monitor.
