1. Field of the Invention
This invention relates to hose reels and, more specifically, to an inlet assembly that may be easily accessed.
2. Background Information
A hose reel typically includes a portable frame assembly that supports a basket assembly. The basket assembly has a central barrel and two end hubs. The basket assembly is structured to have a hose wound thereabout and is rotatably coupled to the frame assembly. The basket assembly also includes one or more conduits structured to couple an external hose to the basket assembly hose. One conduit, the basket assembly conduit, has an inlet end disposed along the axis of rotation of the basket assembly and includes a distal end that extends through the barrel body so that the basket hose may be coupled thereto. The basket assembly conduit rotates with the basket. A second conduit, the inlet conduit, provides the connection with the external supply hose. The inlet conduit has a first end and a second end. The second end is structured to be disposed within the basket assembly conduit inlet end and is disposed along the axis of rotation of the basket assembly. The inlet conduit first end extends from the basket assembly, and may extend from the frame assembly, and is structured to be coupled to the external hose. Typically, the inlet conduit first end extends at generally a right angle to the inlet conduit second end. The inlet conduit second end is disposed within the basket conduit thereby creating a passage for water extending from the external hose, through the inlet conduit, through the basket assembly conduit and into the basket assembly hose. To resist water leakage, the inlet conduit second end typically includes one or more resilient O-rings structured to engage the inner surface of the basket assembly conduit.
When the basket assembly hose is being wound about the barrel, the basket assembly conduit rotates with the basket about the axis of rotation and the inlet conduit remains substantially stationary. In this configuration, the O-rings are subject to wear and tear as the O-rings are the elements at the interface between the inlet conduit and the basket assembly conduit. As such, a hose reel is typically structured to allow a user to separate the inlet conduit and the basket assembly conduit by allowing the inlet conduit to be removed. Once removed, the user can access the inlet conduit O-rings for replacement. The hose reel, however, must also include a device for maintaining the inlet conduit and the basket assembly conduit in place during normal usage.
Various coupling devices are known in the prior art. Initially, the coupling devices were not structured to allow the user to separate the inlet conduit from the basket assembly conduit. Such coupling devices were typically snap clips structured to couple the inlet conduit to the hose reel frame assembly and substantially restrict the motion of the inlet conduit. As manufacturers learned that users desired to replace damaged O-rings, removable clips came into use. These clips, however, have been disposed in difficult to access locations, e.g., between a basket assembly hub and the frame assembly. Such coupling devices typically required the use of two hands and/or the use of tools to disengage.
An inlet conduit assembly for a hose reel assembly as recited in the claims below includes a clip assembly that is structured to be accessible from the outer side of the frame assembly. Further, the clip assembly is structured to be operated without the use of tools. In this configuration, a user may quickly and easily actuate the clip assembly to release or engage the inlet conduit. Thus, a user may quickly and easily remove the inlet conduit so that the O-rings may be replaced or for other reasons. Further, when the user wished to install the inlet conduit, the installation is also easily accomplished.
In one embodiment, the clip assembly includes a pivoting clip body having a clip structure that is, preferably, two pincer-like fingers. The body is coupled to the hose reel frame assembly and structured to pivot. The clip structure fingers extend in the same general plane that the clip body pivots in. The inlet conduit, which is preferably a circular tube, includes a retaining clip groove extending at least partially circumferentially thereabout. When the inlet conduit is fully inserted into the basket assembly conduit, the retaining clip groove is disposed in the plane of the clip body rotation. Thus, the clip body may be pivoted between a first position, wherein the clip structure does not engage the inlet conduit body retaining clip groove, and a second position, wherein the clip structure engages the inlet conduit body retaining clip groove. When the clip structure engages the inlet conduit body retaining clip groove, the inlet conduit is, essentially, prevented from being moved axially. That is, when the clip structure engages the inlet conduit body retaining clip groove the inlet conduit and the basket assembly conduit form a passage from the lateral side of the hose reel to a basket surface outlet.
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:
As shown in
The basket assembly 14 includes a barrel 30, two hubs 32, 34, and a basket assembly conduit 36. The basket assembly 14 is structured to support a basket assembly hose 38. The barrel 30 is, preferably, a cylindrical body 40 having an outer surface 42. The barrel 30, preferably, has a diameter several times larger than the diameter of the basket assembly hose 38. The basket assembly hubs 32, 34 are each disposed on, and are coupled to, a lateral side of the barrel 30. The basket assembly hubs 32, 34 are further rotatably coupled to the frame assembly 12. The hubs 32, 34 define the usable storage space for the basket assembly hose 38 about the barrel 30. The basket assembly 14 is rotatably coupled to the frame assembly 12 and has an axis of rotation extending generally along the longitudinal axis of the barrel body 40. The axis of rotation of the basket assembly 14 is typically horizontal and typically extends laterally relative to the frame assembly 12.
As shown in
The basket assembly 14 further includes an inlet conduit assembly 50 that includes a generally cylindrical, elongated body 52 and a clip assembly 54. The inlet conduit assembly body 52 has a first end 56, a second end 58, and a retaining clip groove 60. The retaining clip groove 60 extends at least partially circumferentially about the inlet conduit body 52. The inlet conduit body first end 56 preferably includes about a ninety degree bend. The inlet conduit body first end 56 is structured to be coupled to an external hose (not shown). That is, the inlet conduit body first end 56 preferably includes threads or another such hose coupling device. The inlet conduit body second end 58 is sized to fit within the basket assembly conduit inlet end 46. The inlet conduit body second end 58 further includes at least one, and preferably two, O-ring grooves 62, 64. An O-ring 66, 68 is disposed in each O-ring groove 62, 64.
As shown in
The shroud assembly 80 may be formed integrally with, that is, molded as part of, the frame assembly 12 or as a separate assembly as shown. Regardless of whether the shroud assembly 80 is integral or separate, the shroud assembly 80 includes a generally planar body 82 with a front side 84, a back side 86, an opening 88 and a generally tubular extension 90. The shroud assembly body 82 is structured to be coupled to the frame assembly 12 adjacent to the basket assembly conduit inlet end 46 and, more preferably, with the axis of the tubular extension 90 aligned with the basket assembly body 40 axis of rotation. The tubular extension 90 extends from the shroud body back side 86 and aligned and in fluid communication with the shroud body opening 88. The tubular extension 90 includes at least one, and in the disclosed embodiment, two clip structure passages 92. The tubular extension clip structure passages 92 are structured to allow the clip structure 76, that is the fingers 77A, 77B, to pass through the tubular extension 90. The shroud assembly body 82 also includes a stop member 94 which is disposed generally opposite the location where the clip assembly body 70 is pivotally coupled to the shroud assembly body 82, as described below. The shroud assembly body 82 may include a notch 96, or similar opening, structured to allow the thumb tab 79 to extend outwardly therefrom as described below.
The inlet conduit assembly 50 is assembled as follows. The clip assembly body 70 is pivotally coupled to the shroud assembly body 82. Preferably, the clip assembly body first end 72 is pivotally coupled to the shroud assembly body back side 86. The clip assembly body 70 travels in a plane aligned with the tubular extension clip structure passages 92. In this configuration, the clip assembly body 70 may pivot relative to the shroud assembly body 82 and move the fingers 77A, 77B through the tubular extension clip structure passages 92. When the fingers 77A, 77B are disposed through the tubular extension clip structure passages 92, the clip assembly body second end 78 contacts the shroud assembly body stop member 94. Further, the thumb tab 79 extends, typically through the shroud assembly body notch 96, outwardly beyond the shroud assembly body front side 84.
The shroud assembly 80 is then coupled to the frame assembly 12. Preferably, the shroud assembly 80 is adjacent to the basket assembly conduit inlet end 46 and, more preferably, with the axis of the tubular extension 90 aligned with the basket assembly body 40 axis of rotation. The tubular extension 90 may be sized to fit about the basket assembly conduit body axially extending portion 49 and may be disposed about the basket assembly conduit inlet end 46. The shroud assembly 80 may be coupled to the frame assembly by fasteners 100, a clip structure (not shown), or any other common means.
In this configuration, the inlet conduit body 52 may be removably installed as follows. The clip assembly body 70 is pivoted to a first position, wherein the clip structure 76 does not engage the inlet conduit body retaining clip groove 60 and does not extend through the tubular extension clip structure passages 92. The inlet conduit body second end 58 is passed through the shroud assembly body opening 88 and the tubular extension 90. The inlet conduit second end 58 then engages, that is, moves into the basket assembly conduit inlet end 46 and is pivotally coupled thereto. At this point, the inlet conduit second end 58 is partially disposed in the basket assembly conduit body axially extending portion 49 and the O-rings 66, 68 sealingly engage the inlet conduit second end 58. Thus, a fluid passage exists from outside the frame assembly 12, through the inlet conduit body 52, through the basket assembly conduit 36, to the outer side of the barrel 30.
However, to maintain the inlet conduit body 52 in this position, the inlet conduit body 52 must be prevented from moving axially. The inlet conduit body 52 is prevented from moving axially by the clip assembly 54. That is, when the inlet conduit body 52 is fully installed, the inlet conduit body retaining clip groove 60 is disposed, generally, within the clip assembly body 70 plane of motion. Thus, the clip assembly body 70 may be moved to a second position wherein the clip structure 76 engages the inlet conduit body retaining clip groove 60. That is, the clip assembly body 70 is pivoted about the pivot point 74 until the fingers 77A, 77B pass through the tubular extension clip structure passages 92 and engage the inlet conduit body retaining clip groove 60. It is noted that the stop member 94 contacts the clip assembly body second end 78 when the clip assembly body 70 is in the second position. In this configuration, the inlet conduit body 52 is, essentially, prevented from moving axially.
Removal of the inlet conduit body 52 is accomplished by returning the clip assembly body 70 to the first position and pulling the inlet conduit body 52 axially until the inlet conduit body 52 has moved out of the shroud assembly 80. It is noted that the movement of the clip assembly body 70 is accomplished easily by a user who engages the thumb tab 79 by hand. That is, there are no tools required to install or remove the inlet conduit body 52 and to move the clip structure 76 into, or from, engagement with the inlet conduit body 52. It is further noted that because the shroud assembly 80 is coupled to the outer side of the frame assembly 12, the thumb tab 79 is easily accessed. That is, a user does not have to remove components of the frame assembly 12 or the basket assembly 14 in order to access the clip structure 76.
While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. For example, as set forth above, the inlet conduit second end 58 is disposed within the basket assembly conduit inlet end 46 and the O-rings 66, 68 are disposed on the outer side of the inlet conduit second end 58. It is understood that such an arrangement could be configured with the O-rings 66, 68 disposed about the basket assembly conduit inlet end 46 and the basket assembly conduit inlet end 46 could be structured to fit inside the inlet conduit second end 58. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
