A stepped or tapered axle is axially received by the hub from only one direction to promote ease of assembly. A mounting plate secures to one end of the axle for mounting the reel assembly to any generally planar surface. A braking system is provided that simply permits free rotational movement of the reel one direction and a drag brake in the opposite direction. A swivel cap of unitized design incorporates retention in the axial and linear directions simultaneously.

Description

BACKGROUND

Reel assemblies are commonly used for storing and using many types of hoses. The common reel assembly design is comprised of a hub, a pair of opposing flanges disposed at the opposite ends of the hub, and an axle upon which the hub may turn. Most reel assemblies leave a manufacturer's location, mostly, if not fully, assembled. This can create a bulky shipment that consumes valued shipping resources. Prior art designs have failed to produce a reel assembly that may be shipped in a compact, disassembled form. Any attempts at such a design have merely created an assembly nightmare for the end consumer. Accordingly, a reel assembly design is needed that permits shipment, storage and sale of the reel assembly in a partially disassembled form. However, such a design should be relatively simple for assembly by end users.

Another common problem found in typical reel assemblies is the fact that the reel assemblies will freely rotate in either direction. Accordingly, when a user pulls hose from the reel assemblies and then stops, the forward momentum of the rotating reel assembly will continue to unreel hose. This can lead to tangling of the hose and simply creates additional reeling for the end user once they are finished using the hose. Braking systems have been previously utilized in various reel assemblies but are either complex in design, which tends to create higher manufacturing costs and propensity for breakdowns, or the braking systems simply provide too little or too much resistance to the unreeling of hose. Furthermore, most prior art braking systems are engaged at all times. Operators must manually disengage such braking systems or reel the hose with the brake engaged. Accordingly, a novel braking system is needed that is simple in design but provides an adjustable measure of braking to the reel assembly, according to a user's needs. Such a braking system should also function so that it is only engaged while the reel is being unreeled.

SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.

A preferred reel assembly of the present invention is provided with a hub, having opposite end portions and an exterior surface that is adapted for supporting a length of hose. In one preferred embodiment, the hub is selectively divisible into at least first and second hub members that are each provided with mating surfaces, which engage one another when the hub is disposed in an assembled position. A pair of opposing flanges project radially outwardly from the opposite end portions of the hub to form an annular channel for receiving the hose. An axle is provided, having first and second end portions, coaxial with the hub, and coupled with the hub in a manner which permits selective rotation of the hub about the axle. In one preferred embodiment, the opposing flanges and the first and second end portions are shaped and sized to permit nesting of the structures into a compact form when the reel assembly is at least partially disassembled. In another preferred embodiment, the axle may be provided in a tapered or stepped form that may only be received by the hub in one direction, thus promoting simplicity of assembly.

DETAILED DESCRIPTION

Embodiments are described more fully below with reference to the accompanying drawings, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

The reel assembly 10 of the present invention is provided for use with a hose 12. The reel assembly 10 is generally comprised of a hub 14, having opposite end portions 16 and 18 and an exterior surface 20, which is adapted for supporting a length of the hose 12. In a preferred embodiment, the hub 14 is selectively divisible into at least a first hub member 22 and a second hub member 24. The first hub member 22 and second hub member 24 are each provided with mating surfaces 26 and 28, respectively, which engage one another when the hub 14 is disposed in an assembled position. While the hub 14 depicted in the Figures is shown to be divided along a plane normal to the long axis of the hub 14, it is contemplated that the hub 14 could be separable along a plane that is co-planar with the long axis of the hub 14. A pair of opposing flanges 30 and 32 project radially, outwardly from the opposing end portions 16 and 18 of the hub 14, to form an annular channel for receiving a length of the hose 12. While not depicted, it is contemplated that, in the event that the hub 14 is divided along a plane that is co-planar to the long axis of the hub, the opposing flanges 30 and 32 could similarly be divided at their midpoints.

An axle 34, having a first end portion 36 and a second end portion 38, is provided to extend co-axially with the hub 14 and be operatively coupled with the hub 14 in a manner that permits selective rotation of the hub 14 about the axle 34. In one preferred embodiment a first bushing 40 and second bushing 42 may be provided to be received adjacent the opposite end portions 16 and 18 of the hub 14 to assist in the rotational movement between the hub 14 and the axle 34. In one embodiment, locking fingers 44 may be positioned adjacent end portions of the first and second bushings 40 and 42, as depicted in FIGS. 5 and 11. The locking fingers 44 may be provided with engagement tabs 46, which are shaped and positioned with respect to the bushings to engage an inner lip 48 of either end portion of the hub 14, as depicted in FIG. 11. In this manner, undesired travel of the first and second bushings along the axle 34 or with respect to the hub 14 is substantially prevented.

To assist in the relative ease with which the reel assembly 10 may be assembled, the axle 34 may be provided to have a shape that is stepped or tapered along its length, leaving the first end portion 36 and second end portion 38 with diameters that are different from one another. In a preferred embodiment, the openings formed through the first bushing 40 and second bushing 42 will be shaped and sized to only properly receive one of the first end portion 36 or second end portion 38 of the axle 34. Likewise, it is contemplated that a preferred embodiment will shape and size the first bushing 40 and second bushing 42 so that they have different outer diameters from one another, so that they may each be properly received by one of the opposite end portions of the hub 14. Accordingly, in this manner, the hub 14, axle 34, first bushing 40 and second bushing 42 may only be properly coupled with one another in one manner. Keys 50 may also be provided along the exterior surface of either bushings that are positioned to mate with keyways 52, formed in one end portion of the hub 14, to ensure that the bushings may only be coupled with their intended end portion of the hub 14. Key 50 further prevents bushing 42 from spinning with respect to the hub 14. By limiting the number of component parts and creating a single manner in which they may properly receive one another, relative ease of assembly is increased greatly. Moreover, assembly is made virtually mistake proof.

In one embodiment, the reel assembly 10 may be mounted to any generally planar surface, using a mounting plate 54, such as that depicted in FIG. 2. Mounting tabs 56 and other such commonly known structures may be provided along the mounting plate 54 to secure the mounting plate 54 to the generally planar operating surface, such as a wall or a frame assembly to any portable or stationary device. An opening 58 should be formed through the mounting plate 54 and sized to accommodate the first end portion 36 of the axle 34. A key 60 and keyway 62 may also be provided on the axle 34, adjacent the first end portion 36, and the mounting plate 54, adjacent the opening 58, to ensure one way alignment for ease of assembly and to substantially limit undesirable rotation of the axle 34 with respect to the mounting plate 54. A lock nut 64 may be axially received along the axle 34 to secure the mounting plate 54 adjacent the first end portion 36 of the axle 34. In this manner, the mounting plate 54 is secured between the lock nut 64 and the first end portion 36 of the axle 34. Mating threads 66 may be provided along the axle 34 to receive the lock nut 64 in a secure fashion. Providing the first end portion 36 of the axle 34 with a diameter greater than the diameter of the opening 58 in the mounting plate 54 will ensure that the axle 34 may not be passed completely through the opening 58 as the lock nut 64 is secured.

In one preferred embodiment, the mounting plate 54 is shaped to have a generally concave rearward surface 68 sufficient to provide a passageway for a length of the hose 12 to extend adjacent the generally planar mounting surface and under the mounting plate 54. In this manner, a feed hose (not depicted) may be passed under the mounting plate 54, through its opening 58, and through an open interior portion of the axle 34. An end portion of the hose 12 may then be joined with a swivel fitting 70, such as that depicted in FIGS. 6 and 7. In one preferred embodiment, a swivel cap 72 is disposed around one end portion of the swivel fitting 70. The swivel cap 72 is provided with a pair of locking tabs 74 that are shaped and sized to be releasably received within recesses or openings 76 formed in the second end portion 38 of the axle 34. Accordingly, as depicted FIG. 7, the swivel cap 72 is dimensioned to be received by the second end portion 38 of the axle 34 in manner that aligns the locking tab 74 with the opening 76. In a preferred embodiment, the locking tabs 34 are provided to be generally resiliently deformable, so that they may be selectively removed from the openings 76. Arms 78 may be provided to extend outwardly from the locking tab 74 in a manner that permits manual engagement of the arms 78 to bias the locking tabs 74 outwardly, thus permitting easy removal of the swivel cap 72 from the second end portion 38 of the axle 34. In its assembled position, the swivel cap 72 prevents the hub 14 from being unintentionally removed from the second end portion 38 of the axle 34. The swivel cap 72 further prevents the torque of the distal end of the swivel fitting 70 from twisting the hose 12, which is attached to the opposite end of the swivel fitting 70.

An elongated hose 12 may be provided to extend from the distal end portion of the swivel fitting 70, through an opening 80 formed through the flange 32. Once the hose 12 is passed through the opening 80 it may be preferable to secure the hose 12 closely adjacent the flange 32, adjacent the hub 14 to provide an orderly and secure position of the hose 12 adjacent the exterior surface 20 of the hub 14. As depicted in FIGS. 10 and 11, a releasable hose clamp 82 may be passed through a pair of openings 84 and 86 formed through the flange 32 and hub 14, and looped around the hose 12. The free end of the hose clamp may be passed through the hose clamp buckle and tightened accordingly. The flexible and releasable nature of the hose clamp 82 will provide it with a long usable life that permit the removal and replacement of the hose 12 with ease.

In one embodiment a braking means is operatively coupled with the hub 14 for resisting rotation of the hub 14 with respect to the axle 34 in at least one direction. One contemplated embodiment of the braking means is depicted in FIGS. 5, 8 and 9. Specifically, a braking ring 88 is shaped and sized to be at least partially received by one end portion of the second bushing 42. At least one finger 90 may be provided to extend outwardly from an exterior surface of the braking ring 88. The finger 90 is preferably shaped and positioned to engage at least one tooth 92 formed in an inner surface of the second bushing 42. While variations on the specific design depicted are contemplated, the stepped and tapered design of the fingers 90 engage the teeth 92 when the braking ring 88 and the second bushing 42 are rotated in one direction, as depicted in FIG. 9. In this manner, the braking ring 88 is frictionally drug by the second bushing 42 across the surface of the axle 34, retarding free advancement of the reel assembly 10. However, rotation of the reel assembly in the opposite direction, typically in the reeling direction, the braking ring 88 remains in a fixed position with respect to the axle 34 and the teeth 92 briefly engage the opposite, tapered surfaces of the fingers 90. In one preferred embodiment, the teeth 92 are disposed at the distal ends of resiliently deformable arms 94. Accordingly, as the fingers 90 and the teeth 92 come into contact with one another the arms 94 and teeth 92 are biased outwardly to permit the fingers 90 and teeth 92 to pass one another. This permits the reel assembly to be reeled with minimal resistance. It is contemplated that the braking ring 88 may be split along at least one portion of its circumference, as depicted in FIG. 5. An adjustment screw 96 may be secured to the braking ring 88 across the split in order to permit selective widening and narrowing of the split. In this manner, the inner diameter of the braking ring 88 may be increased or decreased selectively to adjust the level of frictional engagement between the braking ring 88 and the axle 34 as the braking ring 88 is rotated.

It will be desirable to provide the reel assembly 10 in a form that permits a compact, disassembled structure for shipping and storage. Accordingly, in one preferred embodiment, the first hub member 22 and second hub member 24 should be shaped and sized to permit the two components to be nested closely adjacent one another. More specifically, the end portion 16 of the hub 14 may be provided with an open cavity 98 that is shaped and sized to at least partially nest with the mating surface 28 and exterior surface 20 of the second hub member 24 when the hub 14 is disposed in disassembled position. The generally concave outer surface of the flanges 30 and 32, while promoting the nesting function of the reel assembly 10, further provide a cavity beneath the second hub member 24 that may receive some or all of the remaining component parts to the reel assembly 10 when the reel assembly 10 is packaged for shipment or storage.
