Adaptable water connection for fire fighting equipment and connection device
View Patent ↗Improvements in present day fire hydrants are presented. The improvement relates to a fire hydrant where the above ground structure is essentially removed and is replaced with an adaptable connection. The connection uses the same mounting hole pattern as used in the above ground hydrant. In operation, the adaptable connection is protected by a hinged cover that is opened to provide access to the adaptable connection. The adaptable connection includes a bayonet type connection where a portable fire hydrant is secured and rotated to start the flow of water. The adaptable fire connection eliminates the appearance of the fire hydrant, the potential of a vehicle hitting a fire hydrant and the material cost associated with above ground fire hydrants.
1. A cover and portable fire hydrant comprising:
a flanged base configured for mounting on an existing fire hydrant flange;
the flanged base further having an inner ring wherein
the inner ring has a plurality of engagable slots for engagement with a removable fire hydrant and a valve closure on one side of the inner ring;
the removable fire hydrant has a plurality of mating flanges for engagement into the engagable slots whereby insertion of the mating flanges in combination with rotation of the removable fire hydrant in the inner ring secures the removable fire hydrant onto the inner ring, and
further rotation of the removable fire hydrant in the inner ring opens the valve closure with a first worm pinion gear that turns a second worm gear located at the end of the valve closure with a rack that engages with a pinion configured on one end of the first worm pinion gear.
2. The cover and portable fire hydrant according to claim 1 that further includes a cover that is configured for hinged engagement with the flanged base.
3. The cover and portable fire hydrant according to claim 2 wherein the cover further includes a securing means to retain the cover in a closed and secured condition.
4. The cover and portable fire hydrant according to claim 3 wherein the securing means is with a threaded fastener.
5. The cover and portable fire hydrant according to claim 3 wherein the securing means locks the cover and further requires a key to unlock the cover.
6. The cover and portable fire hydrant according to claim 1 wherein the flanged base or the inner ring has indicia to indicate the rotational direction for opening or closing the portable fire hydrant.
7. The cover and portable fire hydrant according to claim 1 wherein the removable fire hydrant has at least one port for the flow of water through the removable fire hydrant.
8. The cover and portable fire hydrant according to claim 1 wherein the removable fire hydrant further has at least one extension arm for rotating the removable fire hydrant and the inner ring.
9. The cover and portable fire hydrant according to claim 1 wherein the removable fire hydrant has an elastomeric sealing gasket.
10. The cover and portable fire hydrant according to claim 1 wherein the inner ring has a raised annular lip to guide placement of the removable fire hydrant.
11. The cover and portable fire hydrant according to claim 1 wherein the valve closure further includes a sealing surface that mates with the inner ring.
12. The cover and portable fire hydrant according to claim 1 that further includes a sealing gasket between the flanged base and the inner ring.
13. The cover and portable fire hydrant according to claim 7 wherein the at least one port is for at least one of a 2.5″, 3.5″ or 4″ hose.
14. The cover and portable fire hydrant according to claim 7 wherein the plurality of engagable slots allows the placement of the removable fire hydrant to be placed such that the at least one port for the flow of water is orientable in at least two directions.
15. The cover and portable fire hydrant according to claim 1 wherein the removable fire hydrant has at least four mating flanges.
16. The cover and portable fire hydrant according to claim 1 wherein the removable fire hydrant is removable from the inner ring by rotation of the removable fire hydrant in the opposite direction of engagement.
17. The cover and portable fire hydrant according to claim 1 wherein the valve closure is a butterfly valve.
