ABSTRACT:

FIELD OF THE INVENTION
The present inventive subject matter relates to equipment for handling fire hose or the like and more particularly to a new and improved variable size hose winding apparatus especially adapted to coil fire hose and to facilitate removal by a single operator.
DESCRIPTION OF THE PRIOR ART
Many hose roller designs exist. Existing designs can be divided between those that roll the hose up and intend in-place storage of rolled hose, and those that intend for the removal and storage of the rolled hose separate from the hose roller.
Of the prior art hose rollers intending the removal and storage of the wound hose, there are none that satisfy the combined criteria of easy removal, ability to roll various sizes and styles of hose, one-person efficient operation, minimized risk of uncoiling, and easily-stored, round formation of the wound, coiled fire hose.
In general, a problem with these prior art hose winders is that they are not suitable for winding large diameter or relatively heavy, double jacket hoses. In addition, the prior art winders may be difficult for one man to operate and generally lack the portability to be utilized in field operations.
U.S. Pat. No. 5,556,901 discloses a hose winding method and device for use in connection with collapsible hose, such as fire hose. A self-supporting, stand-alone support structure is provided with an elongated crankshaft extending the width thereof. One end of the crankshaft includes a yoke for receipt of a hose couple, and the other end of the crankshaft includes a handle for turning the yoke such that the hose is wound about the yoke. A hose guide is provided upstream of the yoke and includes a stationary hose engagement portion which frictionally engages the hose to force water out of the hose and also to flatten the hose. The hose winder configuration allows for hoses to be wound at a variety of locations and on a variety of terrains. U.S. Pat. No. 5,556,901 is operable by a single person; however, without a guide or back plate for the hose to wind against, it fails to prevent uncoiling.
U.S. Pat. No. 5,205,509 describes an apparatus arranged for selective securement to a receiver socket, wherein the apparatus includes a generally “S” shaped support beam mounting a crank handle at a forward end thereof to rotatably secure a fire hose thereabout. The crank handle includes an extension leg member secured to the crank handle, including an “L” shaped lock leg mounted to the extension leg to secure the hose thereto in a winding operation. The invention further includes a hose mounting bracket, wherein the extension leg is removable relative to the crank arm and securable to the mounting bracket to permit securing and storage of the hose for ease of transport thereof. U.S. Pat. No. 5,205,509 addresses the uncoiling issue; however, it does this through cumbersome spring-loaded arms that must stay with the coiled hose or be removed, in an additional operation requiring additional labor resources.
U.S. Pat. No. 3,946,964 describes an apparatus for rolling a collapsed hose into a roll which includes a frame having a pair of spaced-apart side rails and a crank for rolling the hose between the side rails. One side rail includes a keyed opening which receives the shaft of the crank and an axially extending spaced-apart pin on the shaft when the shaft is in a keyed orientation relative to the opening. The shaft of the crank is borne by both side rails and the axially extending pin cooperates with the shaft to engage a collapsed hose, which is wound about the shaft and pin by cranking a handle portion on the shaft outside the side rails. When the hose is rolled, the shaft and pin are brought into keyed alignment with the opening in one of the side walls and the crank is removed, permitting the rolled hose to be lifted from the frame. U.S. Pat. No. 3,946,964 addresses the uncoiling issue with the use of a side bar on either side of the hose coil being wound. However, this method limits its usefulness to one particular hose size and requires someone to physically pull the coiled hose from between the two side rails.
U.S. Pat. No. 2,960,279 describes a hose roller comprising a frame, including a plate with a planar surface and a wheel rotatably mounted on the frame. The wheel includes a circular disk disposed in a circular opening in the plate with the disk having a face which is co-planar with the planar surface. A stud is mounted on the face of the disk adjacent to the periphery of the disk and a hub is retractably mounted on the axis of rotation of the wheel. The hub is movable between a first projected position and a second retracted position by means of a crank arm. U.S. Pat. No. 2,960,279 while providing a back plate upon which to wind the hose and keep it from uncoiling, ultimately fails to prevent uncoiling because its hub can only be removed, via lever, operated from the opposite side of the apparatus as the winding occurs. This requires an additional person to perform hub removal; otherwise the coiled hose will tend to fall and unwind. Additionally, the pressure from winding makes manual removal of the hub difficult. Finally, the single tine design will often produce egg-shaped coils, rather than the desired and easier to store round-shaped coils.
U.S. Pat. No. 2,396,451 describes a hose reel which has a rectangular frame upon which is mounted a shaft which is rotated by a handle on one end of the shaft. A first disc is attached to the shaft on the end opposite the handle. A plate and a pin are mounted on the face of the first disc. Pivoted brackets secure a retainer disc to the first disc. The shaft is secured to the frame by bearings. The hose is fastened around the pin and then wrapped over the plate. As the shaft is rotated, the hose is reeled between the first disc and the retainer disc into a flat, doughnut-like roll.
U.S. Pat. No. 1,089,285 describes a hose reel comprising a frame having a guide wall and a winding shaft arranged with one end extending through the wall and provided with an attaching device for engaging one end of a hose. The device also comprises means to turn the winding shaft with its attaching device and a forming element mounted for movement to a position parallel with and spaced from the guiding wall and also adapted to be opened outwardly from the wall to permit the removal of a coiled hose from the attaching device.
U.S. Pat. Nos. 1,089,265 and 2,396,451 provide for the positive guiding of the hose while being wound with a hinged door that covers the exposed side of the hose during winding. However, this process requires an additional step both before and after winding and must be separately adjusted for each size of hose being wound.
U.S. Pat. No. 4,198,010 describes an apparatus for winding canvas fire hose into a compact coil comprising a rotatably mounted winding disc for coiling the hose, an electric drive assembly for rotating the winding disc, and a mobile base with an offset leg arrangement for supporting the winding disc and drive assembly. The winding disc is mounted for rotation about a generally horizontal rotational axis and is provided with two support members in the form of a flat support plate and an offset guide pin for supporting a coupling end of the hose while the hose is coiled around the coupling by rotation of the disc.
U.S. Pat. No. 3,124,321 describes an apparatus for winding a fire hose having interlocking coupling members at opposite ends comprising a pair of spaced tines radially spaced for rotating one of the coupling members about an axis extending laterally through substantially its center of gravity and being arranged to align the center of gravity of the coupling member with the axis thereby being dynamically balanced upon rotation thereof. The apparatus further comprises a means for aligning the first edge of the hose radially from the axis as the hose is being wound to facilitate the winding of the hose upon itself.
U.S. Pat. Nos. 4,198,010 and 3,124,321 each provide a back plate for guiding the wound hose as well as motorized operation, but do not provid
