Firehose handle system

Abstract

A firehose handle device that secures to a firehose and nozzle interface. The firehose handle device has two spaced apart handles oriented transverse to the firehose/nozzle coupling when secured thereto. In certain embodiments, the handles may be selectively adjustable relative to each other.

Claims

1. A handle device for a firehose and a nozzle operatively associated thereto, comprising: a front ring dimensioned to both receive a coupling portion of a firehose coupling portion yet not receive a nozzle coupling portion a such a way that, when coupled, said coupling portions sandwich the front ring; a front framing element extending away from the front ring; a front handle extending transversely from the front framing element; a rear ring; a rear framing element extending away from the rear ring; a rear handle extending transversely from the rear framing element; the rear framing element having four or more frame connections holes linearly spaced apart; two front side bracing elements extending from the front ring; two rear side bracing elements extending from the rear ring; the rear side bracing element having four or more side connections holes; and a center support interconnects the front framing element and the two side bracing elements, wherein the center support has two opposing center side connection hole and one center frame connection hole, wherein the holes of the center support are dimensioned and spaced apart to simultaneously engage one of the four or more frame connection holes and one of the four or more side connections holes for each side bracing element so that the rear framing element is selectively adjustable relative to the front framing element.

DETAILED DESCRIPTION OF THE INVENTION

(12) The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

(13) Broadly, an embodiment of the present invention provides a firehose handle device that secures to a firehose and nozzle interface. The firehose handle device has two spaced apart handles oriented perpendicular to the firehose/nozzle coupling when secured thereto. In certain embodiments, the handles may be selectively adjustable relative to each other.

(14) Referring now to FIGS. 1 through 11, the present invention may include a firehose handle device 10 having two selectively spaced apart handles 24/68/90/116 and 28/50/94/118 in a perpendicular orientation relative to a longitudinal axis 200 of a firehose 32 and operatively associated nozzle 36. The rear handle 24/68/90/116 and the front handle 28/50/94/118 are coupled to a front ring 16/42/82/108 by a frame assembly 300. The frame assembly 300 may include a framing element 22/48/88/114 extending from the front ring 16/42/82/108 to a rear ring 12/56/78/104. Side bracing 20/86/112 may also extend between said front and rear rings 16/42/82/108 and 12/56/78/104. Furthermore, a center support 18/45/84/110 may join the framing element 22/48/88/114 and the side bracing 20/86/112. The rear handle 24/68/90/116 and the front handle 28/50/94/118 connect to the framing element 22/48/88/114. The rear handle 24/68/90/116 and the front handle 28/50/94/118 may provide feet 26/70/92 and 30/52/96, respectively.

(15) The frame assembly 300, may as a function of the framing element 22/48/88/114 and side bracing 20/86/112 connected along a periphery of said front and rear rings 16/42/82/108 and 12/56/78/104, define a cylindrical space or possibly a cone space (if one of the rings has a greater outer diameter than the other ring). The side bracing 20/86/112 and framing element 22/48/88/114 give the frame assembly 300 a skeletal configuration. The skeletal configuration and the cylindrical space enable the firehose 32 and its nozzle coupling 34 to slide from and through the rear ring 12/56/78/104 to the front ring 16/42/82/108. Furthermore, the rear ring 12/56/78/104 may provide lug slots 14/58/80/106 dimensioned to accommodate nozzle coupling lugs 35 during this engagement process.

(16) The engagement process further includes a distal face of the nozzle coupling 34 sandwiching the front ring 16/42/82/108 against a proximal face 37 of the nozzle 36 when the nozzle coupling 34 operatively associates with the nozzle 36. This mechanically sandwich of the front ring and passage through the rear ring, makes slipping of the handle position nearly impossible. In certain embodiments, the front ring 16/42/82/108 may be dimensioned and adapted to be sandwiched by the distal face of the nozzle coupling 34 and/or lugs 35, as illustrated in FIG. 4. In certain embodiment, the front ring 16/42/82/108 provides sandwiching structure where the lug slots 14/58/80/106 of the rear ring 12/56/78/104 do not. In some embodiments, an inner radius of the front ring 16/42/82/108 is less than the outer radius of the lug slots 14/58/80/106 the coaxial rear ring 12/56/78/104 so that the distal face of the nozzle coupling lugs 35 pass through the rear ring 12/56/78/104 but not the front ring 16/42/82/108, and thus the “sandwiching structure”. It should be understood that the radius is measured from the longitudinal axis 300, and that the inner radius define voids that which the nozzle coupling 34 and/or lugs 35 can slide through.

(17) Referring to FIGS. 5-7, another embodiment of the present invention may be embodied in an adjustable firehose handle device having a front section 40 movable relative to a rear section 54. As a result, there is a front and rear side bracing 44 and 62 and a front and rear framing element 48 and 64, respectively.

(18) A plurality of spaced apart connection holes 66 may be provided in both the framing element 64 or 48 and in the side bracing 62 or 44 and, complementarily, one or more connection hole 46 in the other sections 40 or 54 framing element and side bracing. Typically, the one or more complementary connection hole 46 will be disposed in the center support 45 for additional shear resistance and other reinforcement when fasteners 72, 74 and 75 engage the connection holes 66 and complementary connection holes 46.

(19) Referring to FIGS. 8-10, another embodiment of the present invention may be embodied in an adjustable firehose handle device 76 having one or more movable handles 90 and or 94, where each movable handle has a handle connector 98 (such as a threaded post) to engage one of a plurality of spaced apart attachment holes 100 and be secured thereto by way of fasteners 97 and 99.

(20) A method of using the present invention may include the following. The frame assembly 300 may be provided. A user 38 may load/thread the firehose 32 through the rear ring until the nozzle coupling 34 sandwiches the front ring to the nozzle 36, removably securing the frame assembly to the firehose 32 and nozzle 36.

(21) Moreover, the present invention does not change the way a firefighter sets up to fight a fire. The device can be attached to the firehose in the fire engine's hose bed. The firefighter would pull the hose into the affected area of the fire and fight in a position conducive to putting out the fire whether that be low on one knee or standing. The firefighter would grab the handles release one hand to open the nozzle and flow water, then take the grip again and start maneuvering the nozzle to put out the flames. These are the same steps used without the bracket; however, the bracket offers much more control and less fatigue as stated above. In short, there is little to no retraining to use the present invention, which can be very important as its use is almost always during a potentially fatal emergency.

(22) Additionally, any industry/field that uses a hose to apply liquid/powder that has to be controlled be a human (i.e. industrial spraying of insecticide, high volume seeding, etc.) would benefit from this same type bracket/handle.

(23) It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
