BACKGROUND
A hose is a flexible tube used for conveying liquids or gases under pressure. The shape of a hose is typically cylindrical. Hoses are made of different materials, for example, nylon, polyurethane, polyethylene, neoprene, canvas, or rubber based on the environment and pressure rating. Hoses are used in gardening, firefighting, underwater diving, agriculture, industries, hydraulics, chemical engineering, and construction. High pressure hoses, made of tight- woven canvas either with rubber lining inside or without lining, are typically used in firefighting where water is discharged through the hose at high pressures using high pressure pumps which, in turn, creates a back pressure on the hose at or near the discharge or outlet section of the hose.
High pressure hoses are often required to be manually held, lifted, or grasped for long periods of time while fighting and extinguishing fires in oil refineries, petrochemical plants, and building structures, for example, apartment buildings, warehouses, etc. Handling these high pressure hoses with a user's hand is difficult. Furthermore, a high pressure hose is difficult to grasp or maneuver when the outside surface of the hose is wet, for example, when the hose is exposed to water from rain, or water discharged from the hose. Firefighters also find it difficult to hold on to, or position the hose due to the back pressure exerted on the hose as the high pressure water is discharged from the hose. Furthermore, maneuvering the high pressure hose to different positions and moving the hose is difficult.
Hence, there is a need for an apparatus that enables a user to handle a hose that is discharging water at a high pressure with an improved grip. There is also a need for an apparatus that enables the user to advance and maneuver the hose without difficulty.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 exemplarily illustrates a perspective view of a hose handling apparatus 100 comprising a support member 101, a generally cylindrical handle 102, a first generally cylindrical curvilinear gripping element 103, and a second generally cylindrical curvilinear gripping element 104. Herein, the generally cylindrical handle 102 is referred to as a "handle", the first generally cylindrical curvilinear gripping element 103 is referred to as a "first gripping element", and the second generally cylindrical curvilinear gripping element 104 is referred to as a "second gripping element". The hose 601 referred to herein is, for example, a high pressure hose as exemplarily illustrated in FIG. 6.
The support member 101 comprises a first end 101a, a second end 101c, and a middle section 101b defined by the section between the first end 101a and the second end 101c. The support member 101 is angled at its middle section 101b. The handle 102 is detachably connected to and substantially perpendicular to the support member 101 at the first end 101a of the support member 101 and is rigidly connected to the support member 101. The first gripping element 103 is detachably connected to and substantially perpendicular to the support member 101 at the middle section 101b of the support member 101 and is rigidly connected to the support member 101. The second gripping element 104 is detachably connected to and substantially perpendicular to the support member 101 at the second end 101c of the support member 101 and is rigidly connected to the support member 101. The handle 102, the first gripping element 103, and the second gripping element 104 form a parallel configuration which is perpendicular to a planar surface 101d of the support member 101. The first gripping element 103 and the second gripping element 104 are positioned on the support member 101 to accommodate, secure and hold a hose 601 positioned between the first gripping element 103 and the
second gripping element 104 as exemplarily illustrated in FIG. 6. The handle 102 provides grip to the user's hand and enables the user to maneuver the hose 601.
Due to the configuration of the handle 102, the first gripping element 103, and the second gripping element 104 that are generally parallel to one another, the handle 102 allows the user to securely grip the hose handling apparatus 100 for maneuvering and advancing the hose 601 gripped between the first gripping element 103 and the second gripping element 104. Furthermore, the mid-sections 103b and 104b of the first gripping element 103 and the second gripping element 104 respectively are concaved with respect to their longitudinal axes 108 and 109, as exemplarily illustrated in FIGS. 1-3, for firmly positioning and securing the hose 601. The first gripping element 103, the second gripping element 104, and the support member 101 are made of a non-corrosive material, for example, aluminum casting, polycarbonate, nylon, etc. The handle 102 is made of a polymer material, for example, plastic, synthetic rubber, etc.
The hose handling apparatus 100 further comprises multiple fasteners 105 that rigidly connect the handle 102, the first gripping element 103, and the second gripping element 104 to the support member 101. The fasteners 105 are, for example, screws, bolts, threaded studs, etc. A pair of generally circular washers 106, made of a flexible material, is provided around the first gripping element 103 and the second gripping element 104, to provide a firm grip to the hose 601 and prevent abrasion of the hose 601. The washers 106 are made of a non-slip, flexible material, for example, neoprene rubber.
FIGS. 2-3 exemplarily illustrate side orthogonal views of the hose handling apparatus 100, showing the fasteners 105 for fastening the handle 102, the first gripping element 103, and the second gripping element 104 to the support member 101. The fasteners 105 rigidly and perpendicularly connect the handle 102, the first gripping element 103, and the second gripping element 104 to the support member 101. As exemplarily illustrated in FIGS. 2-3, the longitudinal axes 107, 108, and 109 of the handle 102, the first gripping element 103, and the second gripping element 104
respectively, form a parallel configuration which is perpendicular to a planar surface 101d of the support member 101.
FIG. 4 exemplarily illustrates a rear orthogonal view of the hose handling apparatus 100. The fasteners 105 are disposed on the support member 101 in a generally angular configuration as exemplarily illustrated in FIG. 4.
FIG. 5 exemplarily illustrates a front orthogonal view of the hose handling apparatus 100, showing the end views of the handle 102, the first gripping element 103, and the second gripping element 104, angularly disposed on the support member 101.
FIG. 6 exemplarily illustrates a user maneuvering a hose 601 using the hose handling apparatus 100. The term "user" as used herein refers to a person using the hose handling apparatus 100, for example, a firefighter. The user positions a high pressure hose 601 in between the first gripping element 103 and the second gripping element 104 to grip the hose 601. The user then grips the handle 102 of the hose handling apparatus 100 and maneuvers and advances the high pressure hose 601 to extinguish a fire.
FIG. 7 exemplarily illustrates a user storing the hose handling apparatus 100 in a turnout coat pocket 701. When the hose handling apparatus 100 is not in use, the user, for example, stores the hose handling apparatus 100 conveniently in the user's turnout coat pocket 701. The hose handling apparatus 100 can be conveniently placed in the user's turncoat pocket 701 for storage.
FIG. 8 exemplarily illustrates a user retrieving the hose handling apparatus 100 from the turnout coat pocket 701. When the hose handling apparatus 100 is required for handling a hose 601 to fight a fire, the user can retrieve the hose handling apparatus 100 easily from the user's turnout coat pocket 701 as exemplarily illustrated in FIG. 8.
FIG. 9 exemplarily illustrates a hose 601 gripped between the first gripping element 103 and the second gripping element 104 and locked using a locking assembly
900. The locking assembly 900 of the hose handling apparatus 100 comprises an elongated member 901 with opposing ends 901a and 901f. One of the opposing ends 90 If of the elongated member 901 is rotatably connected to a free end 104a of the second gripping element 104 using a screw 90 Ie rigidly attached to the free end 104a of the second gripping element 104. Another one of the opposing ends 901a of the elongated member 901 carries a notch 90 Id with a spring-loaded cover 901c provided adjacent to the notch 901d. The spring-loaded cover 901c is rotatably attached at the other one of the opposing ends 901a of the elongated member 901. The spring-loaded cover 901c locks on to a pin 901b protruding from a free end 103a of the first gripping element 103 to secure the hose 601 between the first gripping element 103 and the second gripping element 104. The locking assembly 900 thus prevents the hose 601 from slipping off the hose handling apparatus 100 while the hose handling apparatus 100 is used to grip, maneuver, and advance the hose 601. The hose handling apparatus 100 thereby facilitates easier handling of the hose 601 by the user and also helps the user to withstand back pressures caused by the hose 601.
FIG. 10 exemplarily illustrates an embodiment of the hose handling apparatus 100 showing an elongated slot 1001 provided on the middle section 101b of the support member 101. The elongated slot 1001 is provided on the middle section 101b of the support member 101 along a generally longitudinal axis 110 of the support member 101 to facilitate slidable movement, positioning and attachment of the first gripping element 103 with respect to the second gripping element 104 along the elongated slot 1001 for accommodating hoses of different sizes and diameters between the first gripping element 103 and the second gripping element 104, as exemplarily illustrated in FIG. 10.
To grip a hose 601 of a larger size using the hose handling apparatus 100, a user, loosens the fastener 105 attaching the first gripping element 103 to the support member 101 and slides the first gripping element 103 along the elongated slot 1001 away from the second gripping element 104 to increase the gap between the first gripping element 103 and the second gripping element 104. The user then positions the high pressure hose 601 between the first gripping element 103 and the second gripping element 104. The user
then slides the first gripping element 103 along the elongated slot 1001 towards the second gripping element 104 till the concaved mid-section 103b of the first gripping element 103 firmly accommodates the high pressure hose 601. The user then tightens the fastener 105 to rigidly attach the first gripping element 103 to the support member 101, thereby securing the high pressure hose 601 firmly between the first gripping element 103 and the second gripping element 104. The hose handling apparatus 100 therefore accommodates and grips hoses of different sizes.
FIG. 11 exemplarily illustrates another embodiment of the hose handling apparatus 100 showing finger slots 1101 on the handle 102 for accommodating fingers of the user while the user grips the handle 102 for maneuvering the hose 601. The finger slots 1101 improve the grip of the user on the handle 102, facilitating a firmer and more stable grip when the user needs to hold a high pressure hose 601 to douse a fire with a hydrant.
FIG. 12 exemplarily illustrates another embodiment of the hose handling apparatus 100 showing a hose 601 gripped between a fixed first gripping element 103 and a rollably connected second gripping element 104. In this embodiment, the hose handling apparatus 100 comprises a spindle 111 detachably connected to and substantially perpendicular to the support member 101 at the second end 101c of the support member 101 to form a rigid connection with the support member 101. The second gripping element 104 of the hose handling apparatus 100 is rollably connected and coaxial to the spindle 111. The second gripping element 104 rotates about a longitudinal axis 109 common to both the second gripping element 104 and the spindle 111 for enabling the hose 601 positioned between the first gripping element 103 and the rollably connected second gripping element 104 to roll smoothly on the rollably connected second gripping element 104. The second gripping element 104 freely rotates around the spindle 111. The fixed first gripping element 103 supports the top portion 601a of the hose 601 and the rollably connected second gripping element 104 supports the bottom portion 601b of the hose 601, thereby facilitating the hose 601 to roll smoothly on the rollably connected second gripping element 104 without dragging on the rollably connected second gripping
element 104. The smooth rolling of the hose 601 on the rollably connected second gripping element 104 avoids damage to the hose 601.
FIG. 13 exemplarily illustrates a method of gripping and advancing a hose 601 using the hose handling apparatus 100. A hose handling apparatus 100 as illustrated and disclosed in the detailed description of FIGS. 1-12 is provided 1301. The user positions 1302 the first gripping element 103 and the second gripping element 104 over the hose 601 to securely grip the hose 601. The user then grips 1303 the hose handling apparatus 100 by the handle 102 to maneuver and advance the hose 601 to extinguish a fire. The handle 102 provides a stable grip to the user on the hose handling apparatus 100 for maneuvering and advancing the hose 601 gripped between the first gripping element 103 and the second gripping element 104.
Consider an example where a firefighting unit responds to a call of a fire at a warehouse. The firefighting unit arrives at the scene of a fire and attaches the high pressure hose 601 to a fire hydrant. A firefighter procures the hose handling apparatus 100 from his turnout coat pocket 701 as illustrated in FIGS. 7-8, and positions the high pressure hose 601 on the hose handling apparatus 100. The firefighter then grips the handle 102 of the hose handling apparatus 100 in a firm grip as exemplarily illustrated in FIG. 6. The firefighter then maneuvers and advances the high pressure hose 601 gripped in the hose handling apparatus 100 to spray water at the scene of fire. The hose handling apparatus 100 may be used for handling a hose 601 in applications, for example, firefighting, gardening, transporting oil, hydraulic machinery, etc.
