Fire hose couplings and adapters
View Patent ↗Fire hose couplings and adapters are configured to receive, by any of various types of interconnections, a wide range of attachments enhancing the utility of the associated fire hose. The attachments are secured to the coupler or adapter by way of an appropriate locking engagement, such as by a dovetail connector, setscrews, chemical attachment, adhesives and the like. The attachments cover a broad range of handles, reflective and directional devices, analog and digital sensors/monitors/indicators, and carabiners, and both threaded and unthreaded studs adapted for appropriate receipt of any of a broad range of attachments or uses.
1. A fire hose coupler, comprising:
an annular ring having an outer circumferential surface characterized by circumferentially uniformly spaced dovetail-shaped lugs thereabout configured to accommodate mating connection with devices complementing the utility of the fire hose coupler beyond simply coupling fire hose sections;
said devices being in mating connection with at least certain of said dovetail-shaped lugs; and
wherein said devices comprise rocker lug attachments,
wherein each rocker lug attachment comprises a first side and a second side opposite the first side, wherein said first side comprises a shape complimentary to said outer circumferential surface and is configured to form a dovetail mating interconnection with at least one of said dovetail-shaped lugs, and wherein said second side comprises a rocker lug extending therefrom.
2. The fire hose coupler according to claim 1 , wherein said mating connection is releasable.
3. The fire hose coupler according to claim 2 , wherein a Higbee indicator is interposed between a pair of dovetail-shaped lugs.
4. The fire hose coupler according to claim 2 , wherein said mating connection is effected by a setscrew interengaging said devices and said outer circumference.
5. The fire hose coupler according to claim 2 , wherein said mating connection is effected by an axial taper on at least certain of said dovetail-shaped lugs, achieving a wedged mating engagement.
6. Afire hose coupler, comprising:
an annular ring having an outer circumferential surface of uniformly spaced dovetail-shaped lugs thereabout configured to effect mating key and keyway sliding engagements; and
a plurality of devices taken from a group of operational and safety devices for fire hoses configured to be received by said annular ring through said mating key and keyway sliding engagements and wherein said mating key and keyway sliding engagements are releasable, and further wherein said devices comprise rocker lug attachments,
wherein each rocker lug attachment comprises a first side and a second side opposite the first side, wherein said first side comprises a shape complimentary to said outer circumferential surface and is configured to form a dovetail mating interconnection with at least one of said dovetail-shaped lugs, and wherein said second side comprises a rocker lug extending therefrom.
