FIELD OF THE INVENTION

This invention relates to protective storage devices for flexible hoses particularly of the lawn and garden watering type. In addition, the device of the present invention will greatly facilitate wrapping the hose on the reel and will allow connection to a source of water under pressure without requiring disconnection of the inlet end of the hose wrapped on the reel in the housing.

BACKGROUND OF THE INVENTION

The prior art has proposed a number of different structures for storing a garden hose when not in use. The structures have generally included a reel about which the hose is wrapped for storage. In some of these devices, the hose reel has been rotatable about its axis to facilitate the wrapping and unwrapping of the hose for use. In general, the hose must be completely removed from the reel to enable connection to a source of water. While for relatively short lines of hose, these devices have been useful, for any significant increase in the hose length, these devices have not been satisfactory in view of the difficulty of manipulating the hose relative to the reel when moving between the stored and extended positions of the hose. Generally, manufacturers have avoided the use of complicated gear systems and drive mechanisms for the reel in view of the expense involved. Also, since these types of carrier structures have tended to be exposed to the weather or at least placed in storage conditions for a long period of time, the useful life of such drive mechanisms tends to be unacceptably short. In addition, manufacturers have avoided complications in manufacturing in order to keep the cost of these devices as low as possible.

In many communities, outside storage of a hose is not permitted for a number of reasons including aesthetic considerations, safety and the likelihood of theft. Even where a residential occupant utilizes a reel for storage, moving the wrapped reel out of sight tends to be infrequent where the hose is connected to the water supply. Also, presently available reels generally lack any facility for supporting gardening tools for ease-of-use. With many types of different hose materials, it is important to protect the hose during storage from exposure to direct sunlight to prevent deterioration of the material of the hose where the hose is manufactured with certain inexpensive plastics such as vinyl or woven nylon yet many reel type devices have no shielding for the hose.

SUMMARY OF THE INVENTION

The present invention provides a hose reel carrier assembly which can be easily moved over the ground for use and operated to wrap the hose easily and which will allow easy extension of a length of hose relative to the reel without requiring connection of the length of hose directly to a water source. Instead, the carrier assembly itself is provided with an auxiliary hose length and a conduit system for connection to a water source while the end of the hose length carried on the reel has one end connected to an outlet carried by the reel. When it is desired to store the carrier assembly with the hose wrapped on the reel, the carrier assembly which is provided with wheels can be easily moved back to a storage position such as in a garage or shed. A number of compartments can be provided on the carrier assembly which also serve to shield the hose when wrapped on the reel from exposure to the elements and sunlight and provide storage of garden tools and the like.

In one embodiment, a reciprocating guide is provided that is linked to a manual drive for the reel so that when the reel is rotated by a user, the reciprocating guide will move back and forth across the reel to uniformly and smoothly wrap the hose on the reel to provide a compact storage configuration. Additionally, the carrier assembly includes a fluid joint that allows rotation of the outlet end of the joint with rotation of the reel thus greatly simplifying handling of the hose length. Operation of the reel is also greatly facilitated by an externally accessible handle, the rotary motion of which is linked to the hose guide for synchronous operation.

The foregoing as well as other advantages will become apparent as consideration is given to the following description and accompanying drawings, in which: [0007]

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings, wherein like numerals designate corresponding parts throughout the several views, there is shown in FIG. 1 the carriage assembly [0016] 10 of the present invention. In this embodiment, the carrier assembly 10 includes a front wall 12, two side walls one which is shown at 14, a rear wall 16 and the top wall or lid 18 which may be removable to gain access to a storage area underlying the lid 18.
To facilitate use and movement of the assembly [0017] 10, the rear wall 16 may be formed with depending feet or legs 20 while, adjacent the front wall 12, wheels 22 are rotatably mounted on either a common or separate axles, not shown. The front wall 12 is preferably provided with a storage recess 24 which is provided with a projecting post 26 having an extended width and wings 27 to support and retain a length of auxiliary hose 29 wrapped about the post 26. The auxiliary hose 29 has an end 30 for attachment to a water spigot while the other end is connected to a conduit 30 which, as explained in detail below, is connected to a conduit system connected to the main hose which will be wrapped on an interiorly located reel 42.
The [0018] reel 42 is connected to larger diameter wheels 44 and 50 at each end. The connection may be accomplished in a number of ways such as by epoxy adhesive, interlocking fingers or screws. The wheels 44 and 50 have hubs 45 and 53, respectively, each of which is mounted on an axle, 46 and 48, respectively. The axles 46 and 48 extend concentrically relative to the axis of rotation of the reel 42 which is preferably hollow.
[0019] Support rods 36 and 38 are mounted one above the other and spaced slightly inwardly of the outer edges of front and rear walls 12 and 16 as shown more clearly in FIG. 1. Mounted astride the rods 36 and 38 is a hose guide member 40 which includes a large central opening 54 through which a hose will be positioned in use. As shown more clearly in FIG. 5, the lower opening of the hose guide 40 is provided with a recess 56 on which is mounted a reversing lug 58 which projects outwardly from the inner wall 59 as shown more clearly in FIG. 6. The lug 58 has a shaft 60 positioned in a bore formed through the base of the recess 56 and through an extension 61 and which is surrounded by a spring 62 to resiliently hold the lug 58 in the position shown. With this arrangement, rotation of the lug 58 and shaft 60 will easily be effected when the hose guide 40 reaches one end of its travel on the guide rods 36 and 38. The ends of the lug 58 will ride slidingly in spiral grooves two sets of which are formed in the lower rod 36. The lower rod is rotated by a chain driven by the crank 64 in a selected direction. One set of grooves will effect translation of the guide 40 in one direction while the other set of grooves will effect translation in the opposite direction on the guide rods. When the guide 40 reaches one end of the rods, further rotation of the rod 36 will force the lug 58 to rotate about shaft 60 to engage the other set of grooves and commence movement of the guide 40 in the opposite direction while the crank's rotation can be continued in the same direction.
With reference to FIG. 3, [0020] wall 16 is shown with the spaced apart feet 20 and the hand crank 64 which will be operated by a user to rotate the reel 42 when it is desired to reel in a hose which is connected to the water outlet pipe extending through the surface of the reel 42 as shown at 66 in FIG. 4. Also, as apparent from FIG. 4 and 7, the pipe 66 extends within axle 48 which is hollow and makes sealing contact with a stationary connector tube 49 located within axle 48 by means of one or more than O-rings carried about the exterior of the tube 49 preferably in grooves 51 formed about the circumference thereof adjacent the end thereof that is inserted into the end 69 of pipe 66. As shown in FIG. 7, the reel 42 and wheel 50 are radially spaced from the pipe 66 and tube 49. With the connection end 69 of the pipe 66 disposed about the tube 49, a secure sealing will be effected that allows unhindered rotation of the reel and pipe 66 carried by a slot 67 provided in the inner edge of hub 53. Retaining plates 71 are secured about end 69 and are, in turn, secured as by screws to the axle 48.
In operation, a user will first connect the [0021] auxiliary hose 29 to a spigot at the end 31. The other end 30 of the auxiliary hose 29 is connected to the connecting tube 49 which extends within the axle 48 where the interfitting with the connection end of the pipe 66 takes place. Since the axle 48 as shown in FIG. 7 has a larger diameter than that of tube 49 and the end of pipe 66, no stresses will be transmitted to the seal between these elements. A user will then connect one end of a hose to the opposite end of the pipe 66 that projects through the reel 42 as shown in FIGS. 4 and 7. The opening 54 in the hose guide 40 should be of a size to allow the connecting end of a hose to be inserted therethrough to facilitate this connection. When desired, the hand crank 64 will be rotated to rotate the reel 42 as well as simultaneously reciprocate the hose guide 40 along the guide rods 36 and 38 until the desired length of hose is wound on the reel 42. As shown in schematic form in FIG. 8, the hand crank 64 will have its inner end mounted on a hub 74 to which is connected a sprocket gear or wheel 76. The reel 42 will be connected to freely rotatable pinion 78 which is connected to another sprocket gear 80. Rod 36 is directly connected to a sprocket gear 82 and may be rotatably mounted the wall 16 of the carrier 10. About each of these sprocket gears or wheels 76, 80 and 82 is a sprocket chain 84. With this arrangement, rotation of the sprocket gear 76 by the hand crank 64 will directly effect rotation of the reel 42 connected to the shaft 78 with translation being transmitted through the rod 36 to the hose guide 40. It will be understood that a flexible belt may be substituted for the sprocket chain 84 although a sprocket chain tends to be more durable.
In the carrier assembly [0022] 10, above the reel 42 is a compartment for storage of gardening tools or other artifacts such as alternate nozzles of the hose. The lid 18 may be hinged along one edge. An open basket 34 may be removably suspended by hooks (not shown) from the front wall 12 adjacent the lid 18 in a manner shown in FIGS. 1 - 4.
To facilitate assembly as well resistance to weather conditions, the carrier [0023] 10 should be made substantially of a plastic of the type that is suitable for injection molding such as a polyvinyl carbonate, polyvinyl chloride of relatively high molecular weight.
Having described the invention, it will be apparent to those skilled in this art that various modifications may be made thereto without departing from the spirit of the invention. [0024]
