1. Field of the Invention
This invention relates to hose reels and, more specifically, to a hose reel structured for ease of use and maintenance.
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 base or housing assembly structured to rotatably support a reel, 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 housing assembly, and guide plates which define the usable area of the barrel. The basket assembly also includes a crank, 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 away from the reel 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 reel. 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 reel in a controlled manner. In this configuration, an outlet hose may be coupled to the movable end of the conduit and, when the reel is rotated, the hose is wrapped, or unwrapped, about the reel. Thus, a hose may be transported and/or stored on the hose reel assembly.
The hose reel assembly typically is made of plastic and sold in a disassembled state. While manufactures try to make the assembly of a typical hose reel relatively simple, there are many components of a hose reel assembly that are difficult for some users to install or assemble. As such, manufactures try to include as many preinstalled components as possible. The disadvantage to having preinstalled components, however, is that some components, especially those like the crank handle that extend away from the body of the hose reel, require additional room in the shipping container and/or storage box. Accordingly, some manufactures have devised structures that are partially collapsible, such as a folding crank handle, that reduce the volume/size of the hose reel during shipping. Unfortunately, these structures are also designed to snap into an extended position and not be collapsed again, or, if structured to be collapsible, the crank handles did not provide easy to access to, or identify, release buttons. This situation created other disadvantages, namely users causing wear and tear to the plastic components by forcing the components into the desired configuration.
Another component that has been traditionally subject to wear and tear is the autotrack device. The autotrack device is used to guide the hose as the hose is being wound about the basket. The autotrack device includes two spaced, parallel rods, wherein one rod includes a bi-directional track, and a follower assembly. The follower assembly engages the track and, as the user rotates the basket using the crank, the follower assembly moves back and forth on the two rods. The hose passes through the follower assembly and, as such, the hose is wrapped around the basket in a controlled manner. As the autotrack device is only required during winding of the hose, manufacturers typically structured the autotrack device to be engaged only during the winding of the hose and disengaged during unwinding. This procedure reduces wear and tear on the autotrack device as the autotrack device is only in limited use. Many users, however, have found the present design of the autotrack device release to be difficult to operate. As such, the users will simply leave the autotrack device engaged at all times, thereby increasing the wear and tear.
Additionally, users are also known to have difficulty in disassembling, or at least partially disassembling, the hose reel assembly as is required for certain maintenance operations, such as accessing the water system for lubrication. That is, in the prior art, the water system included a conduit having a generally stationary inlet and a movable outlet. The generally stationary inlet is coupled to the hose reel assembly housing assembly, and has a generally circular pipe extending into the reel. The water system also included a rotating outlet, coupled to the reel, and having a wide diameter pipe extending into the reel. The inlet pipe extended into the outlet pipe. The inlet pipe disposed in the outlet pipe creates the water system conduit. An O-ring, or other sealing device, is disposed at the interface between the inlet and the outlet pipes to resist water leaking therefrom. A user typically needed to substantially disassemble the water system, using tools, for such simple maintenance operations as lubricating the water system O-rings. As such, the maintenance procedures are time consuming and difficult and users simply failed to perform the required maintenance, furthering degradation due to wear and tear.
As such, there is a need for a hose reel that is structured for easy assembly and maintenance.
There is a further need for a hose reel assembly having an easily collapsible crank handle.
There is further need for a hose reel assembly having an easily accessible water system.
There is a further need for a hose reel assembly having an easily engaged/disengaged autotrack device.
These needs, and others, are met by the present invention which provides for a hose reel assembly structured for ease of use and maintenance. The hose reel assembly includes a folding crank handle, having an easily accessible and identifiable release, an easily released water system, and an autotrack device that is easily engaged/disengaged. By improving the ease of use of such components, the amount of wear and tear on the hose reel is reduced and the life of the hose reel is extended. The crank includes a crank arm and a pivotable handle assembly. The handle assembly includes at least one, and preferably two, locking tabs disposed adjacent to the pivot point. The crank includes at least one, and preferably two, finger notches adjacent to the locking tabs. The finger notches provide easy access to the locking tabs when the handle is in the extended position. The locking tabs are flexible tabs that engage the crank arm when the handle is in the extended position. The locking tabs may be released by biasing the tabs away from the crank ann. Moreover, as users are familiar with the shape of the finger notches, users will quickly learn to use the release feature of the locking tabs thereby allowing the handle to pivot freely.
The autotrack device is improved with an easily operable release lever assembly on the follower. The release lever assembly is coupled to the follower housing and includes a lever member, a track engaging member, and a spring. As is known, the autotrack device also includes a rod, or guide bar, having a bi-directional track The track engaging member is an elongated member having one end coupled to the housing, via the lever, and the other end having a tooth structured to selectively engage the guide bar. The spring extends between the housing and the track engaging member and is structured to bias the track engaging member toward the guide bar. The lever member has a grip portion and a cam portion. The grip portion is a generally flat, substantially solid element. The cam portion is a bifurcated yoke wherein the tines have lateral edges which extend outwardly, in both directions, from the plane of the grip portion. The yoke supports an offset support rod. The track engaging member is coupled to the support rod. The lever member is pivotally coupled to the housing. In this configuration, the lever member may be placed in a first or second position. In a first position, the offset rod is located closer to the housing, in the second position wherein the lever member is pivoted about 180 degrees on the housing, the offset rod is spaced from the housing. As the track engaging member is coupled to the offset rod, when the lever member is in the first position, the spring biases the track engaging member into engagement with the guide bar. In the second position, the track engaging member is spaced from the guide bar and the tooth does not engage the track.
The water system includes a stationary inlet member and a rotating outlet member, as is known in the art. The present invention, however, provides an easy release interlock structured to couple the inlet and outlet members. The interlock includes one or more grooves in the outer surface of the inlet pipe, at least one, and preferably two, openings in the outlet pipe, and a locking member having an elongated handle with a yoke. When assembled, the inlet pipe is disposed partially within the outlet pipe with the grove aligned with the openings. The locking member yoke is disposed through the outlet pipe openings and into the inlet pipe groove. In this configuration, the inlet pipe may not move axially relative to the outlet pipe while the outlet pipe may rotate about the inlet pipe. The locking member handle extends to the edge of the basket assembly where it may be easily grasped. To remove the inlet pipe, a user merely pulls the locking member handle radially away from the pipes, thereby disengaging the yoke. Once the yoke no longer engages the inlet pipe groove, the inlet pipe may be moved axially relative to the outlet pipe. That is, a user may pull the inlet pipe out of the basket assembly and housing assembly. The O-rings are, preferably, disposed on the inlet pipe. Thus, the user may apply lubricant to, or replace, the O-rings without having to access the interior of the housing assembly or basket.
A full understanding of the invention can be gained from the following description of the preferred embodiments when read in conjunction with the accompanying drawings in which:

When the crank assembly 50 is assembled, the handle assembly 70 is pivotally coupled to the crank arm 52 with the handle assembly pivot pins 78A, 78B disposed in the handle receptacle pivot openings 64A, 64B. In this configuration, the handle assembly 70 is structured to move between a first, folded position, wherein the handle assembly 70 is disposed partially within the handle pocket 60, and a second, extended position wherein the handle assembly 70 extends about ninety degrees to the crank arm 52. Additionally, when the handle assembly 70 is in the second position, each locking tab 80A, 80B engages a locking edge 66A, 66B. That is, as the handle assembly 70 is moved into the second position, the angled finger pad 86 engages the associated locking edge 66A, 66B causing the locking tab 80A, 80B to flex. Once the finger pad 86 moves past the locking edge 66A, 66B, the locking tab 80A, 80B returns to an unflexed position wherein the locking surface 84 engages the associated locking edge 66A, 66B. With the locking surface 84 engaging an associated locking edge 66A, 66B, the handle assembly 70 may not be pivoted. To release the handle assembly 70, a user must apply pressure to the finger pads 86 thereby causing the locking tabs 80A, 80B to flex. Once the locking tabs 80A, 80B are flexed a sufficient amount, the used may again pivot the handle assembly 70 to the first position. The finger notches 68A, 68B are conveniently disposed adjacent to the finger pads 86 when the handle assembly 70 is in the second position. Additionally, the stop tab 94 is structured to engage the crank arm 52 when the handle assembly 70 is in the second position. Thus, the range of motion for the handle assembly 70 is limited.
The autotrack device 100, shown in
The follower assembly 106 is structured to translate, that is, slide back and forth, between two positions on the guide bar 102 and the retaining bar 104, as described below. As shown in
As shown in
When assembled, the autotrack device 100 is structured as follows. The follower assembly housing 110 is coupled to the guide bar 102 and the retaining bar 104 with the follower assembly housing first side 111 facing outwardly, that is, away from the guide bar 102 and the retaining bar 104. The track engaging member 124 is disposed between the follower assembly housing 110 and the guide bar 102 with the track engaging member first end 162 extending through the track engaging member passage 114 and extending to the follower assembly housing first side 111. That is, in the preferred embodiment, the hook 168 extends through the track engaging member passage 114. The spring 172 is disposed between the track engaging member 124 and the follower assembly housing 110 and biases the track engaging member 124 toward the guide bar 102. The lever member 122 is disposed on the follower assembly housing first side 111 with the hook 168 engaging the offset support rod 130. In this configuration, the spring 172 biases the track engaging member 124, and therefore the hook 168, away from the follower assembly housing first side 111. Thus, the hook 168 draws the offset support rod 130, and therefore the lever member 122 toward the follower assembly housing first side 111 and causes the cam surface 152 to engage the follower assembly housing first side 111. Additionally, the track engaging member tooth 170 is disposed adjacent to the track groove 108 and is structured to engage the track groove 108 as described below.
In this configuration, the lever member 122 and track engaging member 124 are movable between corresponding first positions, wherein the offset support rod 130 is disposed adjacent to the follower housing first side 111 and the track engaging member 124 engages said track groove 108, and second positions, wherein the offset support rod 130 is spaced from the follower housing first side 111 and the track engaging member 124 does not engage said track groove 108. That is, as shown in
In operation, when the track engaging member tooth 170 is disposed in the track groove 108 and the barrel 42 is rotated, the track engaging member tooth 170, and therefore the track engaging member 124, travels axially along the guide bar 102. The motion of the track engaging member 124 is transferred to the follower assembly 106 which also travels axially along the guide bar 102. Thus, as a hose is being wound upon the barrel 42 and passing through the follower assembly 106, the hose is drawn back and forth thereby winding the hose on the barrel 42 in a controlled manner. A controlled manner of directing the hose is not required while drawing the hose outwardly. Accordingly, a user may simply flip the lever member 122 to the second position thereby separating the track engaging member tooth 170 from the track groove 108. In this position, the release lever assembly 120 is not engaged and the autotrack device is subject to a reduced amount of wear and tear.
As shown in
The outlet member 204 has a body 220 that is, preferably, an elongated circular body 220 defining an outlet member passage 222. The outlet member body 220 has a first, upstream end 224 and a second, downstream end 226 (
As shown in
The interlock assembly 206 includes at least one opening 230 on the outlet member body 220, an interlock groove 232 on the inlet member body 210, and a removable, elongated locking member 234 having a handle portion 236 and at least one key member 238. The locking member 234 is structured to be coupled to the outlet member 204. When the inlet member 202 is disposed partially within the outlet member 204, the inlet member interlock groove 232 and the outlet member opening 230 are aligned. In this configuration, the locking member at least one key member 238 is structured to extend through the outlet member opening 230 into the inlet member interlock groove 232, thereby preventing said inlet member 202 moving a substantial distance axially relative to said outlet member 204. Further, the handle portion 236 is disposed on the outer surface of the basket assembly 40. In a preferred embodiment shown in
In this configuration, a user may easily separate the inlet member 202 and the outlet member 204 by removing the locking member 234 and separating the inlet member 202 and the outlet member 204 axially. That is, once the locking member 234 has been removed, the user simply pulls the inlet member 202 out of the outlet member 204. The user may further recouple the inlet member 202 and the outlet member 204 by inserting the inlet member body downstream end 216 partially within the outlet member body upstream end 224 until the outlet member opening 230 is aligned with the inlet member interlock groove 232. When the outlet member opening 230 is aligned with the inlet member interlock groove 232, the locking member 234 may be reinstalled by moving the at least one key member 238 through the outlet member opening 230 into the inlet member interlock groove 232.
