The present invention relates to take-up reels of the type used for winding up and paying out various types of elongated flexible hoses and which automatically rewind the flexible hoses for storage.
Hose reels provide a spool onto which a length of hose may be wound and stored for the convenience of a user. In some instances, the reel is replaced by a partial spool or partial hub which may be fixed to the side of a structure, such as a house, or to a post. In these configurations, whether a reel or a partial spool or hub is used, the purpose is to provide a support for the coiled hose.
Manual hose reels require that once an activity such as watering, washing, fluid dispensing, etc. has been completed, the length of hose that was extended and unwound from the reel is then wound up back onto the reel by hand. This can be achieved by rotating the reel in the proper direction as the extended length of hose wraps itself on the hub of the reel, layer after layer. The rotation of the reel may be performed by directly moving the outer plate end of the spool or may be accomplished by the use of a hand crank that is connected to and rotates the hub of the spool.
In addition to manual reels there are kinetic take-up reels (or simply “take-up” reels) and motor driven reels. Kinetic take-up reels are typically provided with a spring mechanism that stores kinetic energy as the flexible member, e.g. hose is paid out and unwound. When the free end of the flexible member is released, the kinetic energy that is stored in the spring mechanism is used to rotate the reel in a direction that causes the flexible member to be wound back onto the reel. Kinetic take-up reels are typically provided with some type of latch mechanism that will prevent the reel from rotating and rewinding the flexible member until the latch mechanism is released.
There are numerous applications in which a flexible member such as a cable, rope, hose, electrical cord or the like is wound for storage about a take-up reel when not in use. When use of the flexible member is required, an appropriate length of the flexible member it is paid out by unwinding it from the take-up reel. A popular application for this type of mechanism is exemplified by the use of flexible hoses for conducting air, water, oil, grease, antifreeze and the like from a reservoir to a dispensing nozzle. For example, in the typical automobile service station, air is delivered from a compressor tank through a pipe to a spring-loaded take-up reel about which is stored a length of tubular air hose. When air is needed, the air hose is pulled from the reel until the desired length is paid out. When the air hose is no longer in use, the free end is released and a torsional spring acting on the hose reel rewinds the hose back onto the reel.
Portable hose reels are very popular with home owners and particularly gardeners. In portable hose reels the reel is carried by a hand cart or wheeled frame, which can be constructed of a tubular metal or take the form of a molded plastic frame. The purpose of the hand cart, which is normally provided with a pair of wheels, is to enable the length of hose that is disposed on the reel to be moved about the yard or garden area more conveniently. In these arrangements, one end of the hose is connected to a faucet and the other end of the hose remains free while the length of hose in between the two ends is wound onto the reel.
Commercial reels require a number of intricate parts including elements of the basic reel and support structures, the fluid plumbing elements, and rewinding mechanisms. The combination of these various elements and their assembly adds to the overall costs of manufacturing hole reels and increases the possibility of mechanical failure and fluid leakage.
The present invention provides a hose reel that has significantly fewer parts and which can be more easily assembled that present hose reels.
According to various features, characteristics and embodiments of the present invention which will become apparent as the description thereof proceeds, the present invention provides a hose reel which comprises:
a spool for receiving a length of hose thereon;
a mounting bracket;
a fluid inlet tube having a central axis and coupling the spool to the mounting bracket so that the spool can rotate about the central axis of the fluid inlet tube with respect to the mounting bracket; and
a mechanical rewinding mechanism coupled to the spool,
the spool including a hub assembly and a pair of spool flange plates attached to opposite sides of the hub assembly,
the hub assembly comprising, as an integral element thereof, a latch gear having a plurality of teeth that cooperate with a rewinding latch mechanism.
The present invention further provides a hub assembly for a hose reel which comprises, as an integral unit:
a central hub;
a plurality of spokes extending radially from the central hub;
a plurality of hub sections provided at the radial ends of the plurality of spokes which define a cylindrical surface upon which a hose can be wound;
an annular bracing element connected between the plurality of spokes; and
a latch gear provided on the annular bracing element.
The present invention further provides a method of forming a spool for a hose reel which comprises:
a) providing a hub assembly that comprises an integral unitary structure that includes:

The present invention is directed to hose reels of the type used for winding up and paying out various types of elongated flexible hoses. The hose reels of the present invention include mechanical rewinding mechanisms that cause a length of flexible hose unwound from the hose reels to rewind back onto the hose reels when actuated.
The hose reels of the present invention include a hub assembly that comprises, as an integral unit, a central hub, a plurality of spokes extending radially from the central hub, reel hub sections supported by the plurality of spokes, a latch gear and a spring catch. The hub assembly is designed and configured to be molded or cast as an integral unit so as to reduce the number of individual elements of the hose reel and to reduce assembly cost. Moreover, the spool flange plates which are discussed in more detail below can be economically fabricated for use in conjunction with the hub assembly design. The spool of the hose reel comprises the hub assembly and opposed spool flange plates which are fastened together on opposite sides of the hub assembly.
The mechanical rewinding mechanism used in conjunction with the hose reels of the present invention includes a spring housing containing a spiral spring. An outer end of the spiral spring is held in a fixed position with respect to the spring housing and an inner end of the spiral spring is configured to engage the spring catch on the hub assembly when the hub assembly is rotated in a direction to unwind a length of hose on the hose reel.
The spring housing is held in a fixed position when the hose reel is mounted to a support. The spool, i.e. the hub assembly and spool flange plates, rotate with respect to the spring housing. The support for the hose reel can include a mounting bracket that is configured to clear the spool so as not to interfere with the rotation of the spool or a hose being unwound or wound thereon. The mounting bracket can otherwise have any desired configuration required to mount the hose reel on a post, wall, beam, or any other support structure. The hose reels of the present invention include a fluid inlet tube that serves an axis of rotation for the spool, i.e. the hub assembly and spool flange plates. An end of the fluid inlet tube that extends though the hub assembly is connected to a swivel hose fitting that allows a hose to be coupled thereto and extend radially from the end of the fluid inlet tube so that the hose can be wound around the hub reel sections of the hose reel. The hose reels of the present invention can also be provided with hose guides that ensure that a length of hose that is unwound or wound on the reels is guided off and on in such a manner that the hose does not become tangled on the reel. The hose guides can include through-openings which are framed by rollers which reduce friction when a hose is passed though the hose guides. The hose guides are configured so that the through-openings thereof are positioned over a central portion of the hose reel spools.
