This invention pertains to devices for use in the storage of flexible hoses, and more particularly, to a hose reel having a crank handle that can be used to manually wind a hose onto a reel from two different positions.
Hose reel carts for handling and storage of flexible water hoses, such as garden and air hoses, have gained wide public acceptance. While the construction of hose reels is quite varied, such devices are primarily constructed of molded plastic components having a centrally disposed rotatable spool for reeling of the flexible hose, and a frame for supporting of the spool. Portable hose reel carts include wheels at one end of the base of the frame, and a frame handle for tilting the frame onto the wheels to facilitate moving the hose reel. The frame handle may, or may not, be foldable for purposes of shipping and/or storage. For more information concerning the structure and operation of hose reel carts, reference may be made to U.S. Pat. No. 32,510 and U.S. Pat. No. 5,998,552 the teachings of which are hereby incorporated by reference.
Common to hose reel carts is the use of a crank handle secured to a hub for use in rotation of a spool. The spools are typically arranged with the crank handle located at the center of the hub to wind the flexible hose. Attempts have been made to move the location of the crank handle; however, such attempts typically employ the use of a sprocket and chain assembly leaving little in the way of efficiency, ratio gearing, or the ability to compactly store such a device. The advantage of an elevated crank handle is to allow rotation of the spool by an operator who need not bend over to perform the operation. Standing upright lessens the strain on an individual's back, but typically crank movement does not address the change in location for gearing leverage, or address storage of such a device.
For instance, U.S. Pat. No. 1,115,325 discloses a garden hose reel storage device wherein the spool is rotated from a crank mounted a distance above the spool. The remotely mounted crank is coupled to the reel by a chain and sprocket arrangement. A smaller sprocket secured to the hand crank provides a gear reduction to the larger sprocket adjacent to the spool. The direct coupling requires a large diameter spool sprocket that is difficult to shield and prohibits folding of the hand crank support arm.
U.S. Pat. No. 5,388,609 discloses a hose reel cart having a remotely mounted crank handle coupled to a spool by a chain and sprocket assembly. This disclosure utilizes an oversize crank handle thereby reducing the size of sprockets needed to transfer rotation from the hand crank to the hose reel spool.
U.S. Pat. No. 4,974,627 discloses a hose reel cart employing yet another sprocket and chain drive assembly. In this disclosure a crank sprocket is mounted along a side wall of the cart, at a slightly elevated position. The hand crank remains well below the cart handle. Thus, the device fails to take advantage of the highest point on the cart and continues to force the operator to crank the spool from a lower position. Further, the chain assembly must be mounted in the side wall as there is no teaching to place the chain assembly into a foldable cart handle.
U.S. Pat. No. 6,908,058 discloses a hose reel cart having an elevated crank wherein the crank is integrated into an arm of the hose reel handle, the contents of which is incorporated herein by reference.
Thus, what is lacking in the art is a hose reel cart having a hand crank formed into a foldable arm member wherein operation of the hand crank allows manual rotation of a hose reel from two different positions with the hand crank remaining in rotatable contact with the hose reel spool at all times.
Among the several aspects and features of the present invention may be noted the provision of an improved hose reel cart having a hand crank for use in rotation of the reel spool wherein the hand crank is positioned within a foldable arm member. In an additional embodiment, the hand crank is also used for movement of a hose guide for positioning of the flexible hose around the hose reel spool.
The hose reel cart of the present invention is of a shape and design so that the hose reel cart may be preassembled at the factory, thereby eliminating the need for assembly and associated product packaging. Preassembly of the hose reel cart permits the use of a modular frame construction for support of a hose to be wound into a coil of multiple layers with adjacent turns of each layer touching each other by use of a directional spool rotatably coupled to a frame. The hose is wound around the spool by use of a movable hand crank providing, an indirect rotational link between the crank and the winding of the spool. In the preferred embodiment, the crank is positioned in a foldable crank arm assembly that allows for ease of transporting fully assembled hose reel carts and subsequent storage. The crank arm can then be used in at least two positions; a stored position providing the consumer with a hand crank position that approximates the top of the hose reel cart housing; and a raised position wherein the hand crank position is above the top of the hose reel cart housing, providing the consumer with a hose reel that reduces the amount of bending required to reel in a hose. The cover is hinged, providing access to the hose reel and provides a stabilizing platform for the crank arm. A hand-grip on the hand crank can also be placed in a storage position by pivoting the hand-grip about one end of the crank arm. The hand-grip includes a releasable lock for securing the hand-grip in a parallel position with the crank arm for storage, and securing the hand-grip in a perpendicular position to the crank arm for ease of gripping.
Thus, an objective of the instant invention is to provide a hose reel cart having a multiple position crank arm allowing the consumer to re-wind the hose from a typical as well as an elevated position, wherein all components are preassembled so as to eliminate the need for assembly by the consumer.
Another objective of the instant invention is to disclose the use of a cart cover that allows the crank handle to be locked in either a storage position or a raised position.
A further objective of the invention is to provide a hose reel cart having an elevated crank handle that can position a hose guide in addition to providing rotation to the hose reel hub.
Yet another objective of the invention is to provide a hose reel cart having a raised hand crank that may be folded into the cart housing for ease of shipping and storage.
Still another objective of the invention is to provide a hose reel cart that allows a crank arm assembly be raised to a height of about 31.5 inches from the bottom surface to the centerline of the crank handle.
Still yet another objective of the invention is to provide a fixed tray within a hose reel enclosure that provides structural support to the hose reel housing and further supports the raised crank arm assembly in its raised position.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of the specification and include exemplary embodiments of the present invention and illustrate various objectives and features thereof.
