BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to hose reels and, more specifically, to a hose reel structured to swivel so that the hose reel is less likely to topple when a user moves the extended hose.
2. Background Information
Hose reel assemblies are devices structured to assist in transporting and using hoses, typically garden hoses for dispensing water. Generally, the hose reel assembly includes a hose support assembly structured to rotatably support a reel assembly, or “basket assembly.” The basket assembly's primary components are a barrel, around which an outlet hose is wrapped, two hubs which are coupled to the hose support assembly side members, and guide plates which define the usable area of the barrel. The basket assembly also includes a crank assembly, used to turn the basket primary components, and a water conduit having a movable outlet and a generally stationary inlet. The stationary inlet of the conduit extends along the axis of the barrel and is structured to be coupled to a supply hose which is further coupled to a water supply. The movable outlet of the conduit is disposed on the circumference of the barrel. The outlet hose is coupled to the movable outlet and is used to deliver water to the end use. Hose reel assemblies also may include an autotrack device structured to wind the outlet hose on the barrel in a controlled manner. The autotrack device is, typically, located on one side of the hose support assembly. In this configuration, an outlet hose may be coupled to the movable end of the conduit and, when the barrel is rotated, the hose is coiled, or uncoiled, about the barrel. The hose support assembly also may include a wheel assembly that allows a user to move the hose reel assembly from one location to another. The wheel assembly, typically, does not support the hose reel assembly when the hose reel assembly is stationary. In selected embodiments, the hose support assembly may have a vertical height of about three feet with a handle located near the upper end, the basket assembly disposed at a medial height, and the wheel assembly disposed at the bottom. This configuration allows the user to tilt the hose reel assembly onto the wheel assembly when the hose reel assembly must be moved. With the handle located near the top of the hose reel assembly, the user is not required to bend over in order to move the hose reel assembly. Thus, a hose may be transported and/or stored on the hose reel assembly. In other embodiments, the hose reel assembly does not include an elongated handle and is generally box-like.
One disadvantage of any hose reel assembly is that the hose support assembly may be unstable. That is, when a user moves an extended outlet hose a force is applied to the hose support assembly. This force is typically applied to the hose support assembly at the autotrack device. That is, as the hose extends from the autotrack device, the force created by a movement of the hose is transferred to the autotrack device which is coupled to the hose support assembly. When this force is applied in a direction that does not pass through, or generally near, the center of gravity of the hose support assembly, the moment arm on the hose support assembly may cause the hose support assembly to topple. Such a force is often created when a user moves the outlet hose laterally relative to the hose support assembly. That is, the center of gravity of the hose support assembly is typically located near the physical center of the hose support assembly, whereas the autotrack device is spaced from the center of gravity of the hose support assembly; accordingly, when a force created by moving the outlet hose is applied to the autotrack device, a moment arm is created that may cause the hose support assembly to topple. The force of the moment arm is greater when the outlet hose is moved laterally relative to the autotrack device.
Accordingly, there is a need for a hose reel assembly structured to minimize the force of the moment arm applied to a hose support assembly when the outlet hose is moved laterally.
There is a further need for a hose reel assembly structured to resist being toppled by a lateral movement of the outlet hose.
There is a further need for a pivot assembly that may be coupled to a hose reel support assembly.
SUMMARY OF THE INVENTIONThese needs, and others, are met by the present invention which provides a hose reel assembly having a hose support assembly rotatably coupled to a base assembly. The hose support assembly of the present invention is similar to the hose reel described in U.S. patent application Ser. No. 11/385,206, which is assigned to the assignee of the present application and is incorporated herein by reference. The hose support assembly is coupled to the base assembly by a pivot assembly having a first component disposed on a bottom plate that is coupled to the hose support assembly and a second component disposed on the base assembly. The vertical axis of the pivot assembly extends through, or near, the center of gravity of the hose support assembly. In this configuration, when a user applies a lateral force to the outlet hose, the hose support assembly will rotate on the base assembly so that the line of action of the force passes through, or near, the center of gravity of the hose support assembly. In this manner the moment arm created by the force is reduced and the likelihood of the hose support assembly toppling is also reduced. Additionally, the base assembly may be weighted which also reduces the chance of the hose support assembly toppling.
The pivot assembly includes a torus-shaped race and a corresponding torus-shaped track. The bottom plate of the pivot assembly includes a large medial opening which the race extends about. This configuration is desirable compared to a pivot assembly having a circular bearing as the friction between the pivoting components is reduced and this configuration reduces costs. That is, unlike a circular bearing wherein the entire surface area of the bearing creates friction, a torus-shaped assembly has a limited bearing surface. Further the track preferably includes a plurality of protruding ribs that reduces the total contact area between the pivoting components. Also, a torus-shaped assembly includes a large opening thereby reducing the amount of material required to manufacture the components. As such components are typically made from a plastic and typically made in large numbers, the reduction in the amount of materials required results in a significant cost savings.

The bottom plate planar member 150 also includes a coupling device 160 structured to removably fixedly couple the bottom plate 13 to the hose support assembly 12. Preferably, the bottom plate coupling device 160 includes at least one horizontal tab 162 extending from one side of the planar member 150 in a plane generally parallel to the upper side 152. The bottom plate horizontal tab 162 is structured to be disposed over a first horizontal surface 164 (
In this configuration, the bottom plate planar member 150, and therefore the pivot assembly 16, may be removably fixedly couple to the hose support assembly 12. That is, the bottom plate horizontal tab 162 is moved generally horizontally, but also at a slightly upwards angle, over the hose support assembly first horizontal surface 164. Once the bottom plate horizontal tab 162 is disposed over the hose support assembly first horizontal surface 164, the bottom plate locking tabs 166, 168 are moved upwardly to engage the hose support assembly second horizontal surface 178. As each bottom plate locking tab latch angled upper surface 177 engages the hose support assembly second horizontal surface 178, the bottom plate locking tab flexible body 170, 172 moves inwardly thereby allowing the bottom plate locking tab latches 174, 176 to move over the hose support assembly second horizontal surface 178. Once the bottom plate locking tab latches 174, 176 are over the hose support assembly second horizontal surface 178, each bottom plate locking tab flexible body 170, 172 returns to the generally perpendicular configuration and the bottom plate locking tab latches 174, 176 engage the hose support assembly second horizontal surface 178.
As shown in FIGS. 8 And 9, the base assembly 14 includes a generally planar base plate 190 having an upper surface 192. The base plate 190, preferably, has a weight that is heavy relative the hose support assembly 12. That is, the base plate 190 is preferably made from metal, or a plastic shell filled with a granular material, such as, but not limited to, sand.
As shown in
The race 200 is disposed on the bottom plate planar member lower side 154. The race 200 is, preferably, a channel having two generally parallel sides 214, 216 and an inner surface 218. The race inner surface 218 extends between, and is generally perpendicular to, the race sides 214, 216. The race 200 width is defined by the radial distance between the race sides 214, 216. The race 200 width is slightly wider than the track outer surface 210 and, as such, there are gaps (not shown) between the race sides 214, 216 and the track sides 206, 208. Preferably, the combined width of the gaps is about 0.025 to 0.1 inch, and more preferably about 0.05 inch. However, due to manufacturing tolerances and the hose support assembly 12 shifting on the base assembly 14, the race sides 214, 216 and the track sides 206, 208 may contact each other at times. Further, as set forth below, the track outer surface 210 and the race inner surface 218 are not in contact over their entire surfaces.
The pivot assembly 16, preferably, includes a linking device 230 structured to maintain the pivot assembly first component 18 and second component 19 in a rotational relationship. The linking device 230 also includes a first component 232 disposed on the hose support assembly 12 and a second component 234 disposed on the base assembly 14. As shown, the linking device first component 232 is a plurality of flexible tabs 238 each having a generally perpendicular latch 240. Each latch 240 has an angled distal surface 241. The tabs 238 extend generally parallel to the axis of rotation of the pivot assembly 16. The linking device second component 234 is a torus-shaped latch surface 242 that extends generally perpendicular to the axis of rotation of the pivot assembly 16 and adjacent to the track 202. As shown, the latch surface 242 extends generally inwardly from the track 202 and tabs 238 are disposed within the perimeter of the latch surface 242 with the latches 240 extending generally outwardly from the tabs 238, however, these elements may be configured in other orientations. For example, the latch surface 242 could extend radially outwardly from the track 202 and tabs 238 could be disposed in a wider radius than the latch surface 242 with the latches 240 extending generally inwardly from the tabs 238 (not shown).
The pivot assembly 16 also includes a friction reduction device 250 structured to reduce the friction between the track outer surface 210 and the race inner surface 218. The friction reduction device 250 includes either, and preferably both, a plurality of fixed bearings 252 and/or “grease” 254 as defined above. The fixed bearings 252 are raised portions on the track outer surface 210, or the race inner surface 218, having an outer contact surface 256. By having the fixed bearings 252 extend above the generally flat portion of the track outer surface 210, the total area of contact between the track 202 and the race 200, that is, the sum of all fixed bearing contact surfaces 256, is reduced thereby reducing the amount of friction therebetween.
If the friction reduction device 250 does not include grease 252, the sum of the fixed bearing contact surfaces 256 is preferably 3% to 15%, and more preferably 6% of the total race inner surface 218 area. The fixed bearings 252 are preferably raised hemispheres or, as shown, elongated radial ribs 260.
In the preferred embodiment, the friction reduction device 250 includes both fixed bearings 252 and a grease 254. In this embodiment, the fixed bearings 252 are preferably raised elongated radial ribs 260 having a length that is less than the width of the track outer surface 210. In this configuration, the fixed bearings 252 act as grease traps 270. A grease trap 270 is structured to resist, but does not prevent, the rotational movement of the grease 254 around the track 202. That is, the grease 254 may still flow around the rib 260 as the rib 260 does not extend completely across the track 202. In operation, as described below, the grease 254 tends to be moved against a rib 260 and, as the grease 254 accumulates, small quantities of grease 254 will flow over the rib 260 and onto the contact surface 256. In this manner, the grease trap 270 maintains a quantity of grease 254 adjacent to each rib 260 and provides lubrication for each rib 260. Thus, the chance of the contact surfaces 256 being non-lubricated is reduced.
The ribs 260, preferably, extend alternately from opposing track sidewalls 206, 208 toward the center of the track 202. In this configuration, and in view of the closeness of the race 200, the grease 254 is typically moved toward the center of the track 202 as the hose support assembly 12 rotates on the base assembly 14, as described below. By directing the grease 254 towards the center of the track 202, the grease 254 is less likely to migrate away from the contact surfaces 256. However, it is acceptable, and even preferred, for a limited quantity of grease 254 to migrate into the gaps 220, 222 to reduce the friction between the race sides 214, 216 and the track sides 206, 208. Migration of the grease 254 may further be limited by ridges 272, 274, extending outwardly from the track sides 206, 208. The ridges 272, 274 have a height that is less than the ribs 260 and, as such, are not contact surfaces 256. Further, because the ridges 272, 274 are shorter than the ribs 260, small amounts of grease 254 may still pass into the gaps 220, 222 and reduce friction on the lateral surfaces of the track 202 and race 200.
The friction reduction device 250 may also include at least one closable grease port 290 structured to allow grease 254 to be added to the track 202. The grease port 290 is a passage 292 through the track outer surface 210, or alternately the race inner surface 218, having a removable cap 294 or similar device. Preferably the passage 292 is disposed generally at the center of the track outer surface 210, that is, about an equal distance from each track side 206, 208.
The pivot assembly 16 is assembled by placing the race 200 over the track 202 so that the race inner surface 218 engages the contact surfaces 256. As the hose support assembly 12 moves into position, the latch distal surface 241 engages the latch surface 242 and causes the flexible tabs 238 to move inwardly thereby allowing the latches 240 to move below the latch surface 242. Once the latches 240 move below the latch surface 242, the tabs 238 return to the original position and the latches 240 engage the latch surface 242. Thus, when the hose support assembly 12 is lifted, the latches 240 engage the latch surface 242 and prevent the separation of the hose support assembly 12 from the base assembly 14. In this configuration, the hose support assembly 12 will rotate relative to the base assembly 14 about a vertical axis extending, generally, through the center of the pivot assembly 16.
The hose support assembly 12 has a horizontal centerline extending from the front side, where the autotrack device 100 is located, to the back side. The base assembly 14 also has a horizontal centerline extending from a front side to a back side. When said hose support assembly 12 centerline is aligned with said base assembly 14 centerline, the hose support assembly 12 is in a first, neutral position, and the hose support assembly 12 is structured to rotate about ninety degrees clockwise and ninety degrees counter-clockwise from the neutral position. As such, when a lateral force is applied to the hose support assembly 12, the hose support assembly 12 will rotate relative to the base assembly 14 thereby reducing the angle at which the lateral force effects the hose support assembly 12. Because the angle at which the lateral force effects the hose support assembly 12 is reduced, that is, because the force is applied through, or close to, the center of gravity of the hose support assembly 12, the chance of the hose support assembly 12 toppling is reduced.
