B~CKGROUND OF_T~;~ INVENTtON
It i5 generally recognized that in many instances it is desirable to provide a means Eor storing a hose, such llas a garden hose. It may not be necessary to use a hose at ja considerable distance from a water source. In many , application, it is only necessary to use a hose a short distance from the water source and then in another instance, use the hose a difEerent c1istance from the water source.
ccordingly, it is desirable to provide a means for storinq l¦the hose with a free end wllich may have a nozzle attached thereto or may be adapted to be connected to another piece !l of equipment, such as a lawn sprinkler. The inlet to the ~hose should be connected to a source of fluid, such as, !¦water, so that a selected length of hose may be removed ¦,from the storage device and the hose may be utilized.
¦¦device which i8 well-known for providing a means for storing ~a hose and being capable of connectin~ the hose to a source jof water is a garden hose reel shown in U.S. I,etters Patent I,No. 2,6~2,312, issued June 16, 1953, to Thomas Shine. The !Shine Patent teaches a hose reel wherein the inlet end of the hose may be secured to a source of water on the reel and the hose then may be wound onto the reel. This arranqement i8 perfectly advantageous for those arrangements wherein the hose may remain at a fixed location. However, when it is Idesirable to move the llose from one location to another, the ¦Shine device does not lencl itself to easy movement.

Furthermore, it is to be noted that in tho Shine device the weight of the hose and water is supported by the pipe which delivers the water.
1 An apparatus which provides a means for not only storing the hose, but also provides a means for transport-ing the hose is disclosed in U.i7. Letters Patent No. 3,587,625 to ~7illiam E. Cowley, which patent issued on June 2B, 1971, and i3 entitled "Transportable Hose Reel." The Cowley patent Idisclo8e~ a reel for storing hose which reel also provides la support for the entire device. The reel is mounted in a handle whlch may be positioned on a supporting surface in a manner which allows the reel to rotate on the handle.
The reel is connected to a water supply through a hose section jwhich delivers water to the reel and then to the hose mounted on the reel.
U.S. Letters Patent No. ~,137,939 to Ho Chow, issued February 6, 1979, entitled "Hose Reel Cart", teaches a construction for a hose reel cart wherein a handle also ~provides a frame for supporting a hose reel. The hose ~reel receives a hose, and the frame has a pair of wheels for movably supporting the cart durinq transfer from one location to another. Hoth the Chow and Cowley devices have their supports provide a double function in that the support Eor ,the reel also provides a conduit Eor the water. It has been Z5 found in practice that when a reel is supported by a conduit, ¦Igasket material in the reel tends to wear quickly and thereby li j!

, ;
jallow leaks to develop. It has also been found that the heretofore known reels are made of metal which has a tendency to rust when a protective surface becomes damaged or is w~rn ~away through usage. The reel tends to become rusty and ¦Inot rotate freely. Also, other parts tend to become inoperative due to rusting.
It is also to be noted that in many instance, it is desirable to store the entire apparatus with the hose on lt in a minlmum of space. The Shine device is adapted 0 llto be mounted on a pipe. Thuse, the Shine device must be removed for r;torage. As to the Cowley and Chow devices, the devices may be conveniently moved to a storage location.
j,llowever, the upwardly extending handles tend to take up space ¦,needlessly .

Crank 30, which is molded polyethylene, may be best jl seen in Figure 11. Crank 30 includes a mounting plate 204 which has a crank stud 206 formed therein which stud 206 fits into the journal~ The mourtinq plate has a crank arm !1 210 fcrmed integral therewith, and a crank handle 212 is formed integral with the arm 210.
The instant device may be economically manufactured in I view of the fact that the reel is made of two identical molded polyethylene reel halves which are held together hy screws. Since the reel is made of polyethylene, it does not ,I corrode when exposed to water and air. The construction is such that the reel includes journals wllich eit into the Il Erame. It i5 important to note that the weiclht o'c the hcse, water and reel rests on che journals. The source o~ water i; to a hose which is mounted on the reel is through a conventional ¦ connoator, or inlet hose 214 which is connected to the inlet tube. The water flows through the inlet tube throuah the j hub and into outlet tube 162. lt is to he noted that there l is no load on the inlet tube. Thus, there is no undue wear of 0-rings 176 and 178 which Eorm the seals between the inlet tube and the journal.
¦ It is also to be noted that handle 24 may be conveniently Il lowcred to ~rovide a low storaqe pro~ile for the apparatus i! aftcr a hose has heen placed on the reel. The end of the stored hose is connected to the outlet tube. Cran~ 30 is used to wlnd the hose onto the reel. During tile windincJ
operation, tlle operator may place his foot on step 68 in Il order to steady the apparatus. ~fter the hose has been 1l wound onto the reel, the hose may be transportcd simply by I!
Il -12-~-~z~
pulling down on the handle to Lilt the frame, and ~heeling the apparatus on wheels 72.
! In order to store the apoaratus in a limited space, the ;handle may be folded down. The handle is released from the frame simply by pressing on the press pl~tes lO~ to release ! the hooks from the rods. The handle then may be fold~d down i to the attitude shown in dotted farm in Figure 2, wherein lateral bars 82 and 84 rest on the respective upner beams and uprights 88 and 90 lie along respective slopinq upriqht of the frame. Thus, tho apparatus provides a low profile ,f~ 1l for storage in a limited space. ~1hen it is necessary to llutilize the ~andle again, it is a gimple matter to pivot the ¦.handle about the ears until the rodg engage the res~ective jjhandle locka thereby sccur-ny Lhe handle in its upriqht ¦1 attitude with the lower side of each of the lateral ~ars in engagement with the respective upper beams.
From the foregoing, it may be seen that substantlally all o the parts are of a durabla piastic material which does not rust when exposed to water and air. Therefore, the 1idevice has a long life and also is lightweight so that it , may be handled easily and conveniently.
¦l Although a specific embodiment of the herein disclosure ¦¦ invention has been shown and described in detail, it is to ¦¦be expressly understood that the instant invention is limited ¦¦ only by the appended claims.
