The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
a and 1b are perspective views of a reel 1 according to one embodiment of the present invention, comprising a support assembly 110 and a spool assembly 10. The support assembly 110 is configured to support the spool assembly 10 so that the spool assembly 10 may rotate relative to the support assembly 110. Such a configuration allows the spool assembly 10 to wind or dispense a hose, cord, or cable (not shown). One skilled in the art will appreciate that the terms “hose,” “cords,” or “cable,” as used herein refer to any flexible elongate item suited to be wound or stored on a reel. Such a flexible elongate item may be, for example, a tubular hose, such as a round or flat hose for transporting a gas or liquid; electrical cable; rope; yarn; string; continuous sheet-like material; steel cable; chain; or the like. Similarly, references herein to a “reel” or a “hose reel” refer to a reel apparatus for winding, dispensing, transporting, and/or storing any such flexible elongate member as disclosed herein.
The support assembly 110 comprises two opposing support endplates 120 connected by elongate support endplate connecting members 130. In one exemplary embodiment, the two opposing support endplates 120 are generally planar, and are substantially similar. That is, in some instances, a single support endplate configuration is capable of being used as either or both of the two opposing support endplates 120 of the support assembly 110. According to one advantageous aspect, the single support endplate configuration is used as both of the two opposing support endplates 120. The elongate support endplate connecting members 130 may be, for example, generally cylindrical and are attached at each opposing end thereof to one of the two opposing support endplates 120. In one embodiment, the support endplates 120 each define apertures 122 configured to receive the ends of the support endplate connecting members 130 for connecting the support endplate connecting members 130 to the support endplates 120. The support endplate connecting members 130 cooperate with the support endplates 120 to define a predetermined support assembly width W1, which is defined herein as the distance between the support endplates 120. The support endplates 120, the support endplate connecting members 130, and the manner in which the support endplate connecting members 130 are connected to the support endplates 120, are discussed in greater detail herein, for example, with reference to
The spool assembly 10 is similarly comprised of two opposing spool endplates 20 connected by elongate spool endplate connecting members 30. In one exemplary embodiment, the two opposing spool endplates are generally planar, and are substantially similar. That is, in some instances, a single spool endplate configuration is capable of being used as either or both of the two opposing spool endplates 20 of the spool assembly 10. According to one advantageous aspect, the single spool endplate configuration is used as both of the two opposing spool endplates 20. The elongate spool endplate connecting members 30 may be, for example, generally cylindrical and are attached at each opposing end thereof to one of the two opposing spool endplates 20. In one embodiment, the spool endplates 20 each define apertures 22 configured to receive the ends of the spool endplate connecting members 30 for connecting the spool endplate connecting members 30 to the spool endplates 20. The spool endplate connecting members 30 cooperate with the spool endplates 20 to define a support surface between the two spool endplates 20 for supporting the hose, cord, or cable, and further determine the spool assembly width W2, which is defined herein as the distance between the spool endplates 20. The spool endplates 20, the spool endplate connecting members 30, and the manner in which the spool endplate connecting members 30 are connected to the spool endplates 20, are discussed in greater detail herein, for example, with reference to
As shown in
The spool assembly 10 is assembled with the support assembly 110 to form the reel 1, wherein the reel 1 may further include a mechanism for driving the rotation of the spool assembly 10 relative to the support assembly 110. In some instances, the drive mechanism for the reel 1 may be actuated to rotate the spool assembly 10 in a first direction in order to wind the hose, cord, or cable onto the spool assembly 10. The drive mechanism may also be actuated to rotate the spool assembly 10 in a second direction, opposite to the first direction, in order to dispense the hose, cord, or cable that is already wound onto the spool assembly 10.
The motor driven system of
b illustrates one embodiment of a hand crank system that may be implemented in conjunction with the reel 1 in order to drive the rotation of the spool assembly 10. A hand crank support assembly 165 is coupled to a support endplate 120 and attached thereto with appropriate fasteners via apertures 129. In some instances, such as that shown, four substantially identical sets of apertures 129 may be provided, two sets being defined by each support endplate 120. Such provisions may provide the flexibility as to where the hand crank support assembly 165 is located and may provide easier assembly of the reel 1 regardless of which respective endplate is used on either side of the reel 1. The hand crank support assembly 165 rotatably supports a hand crank driveshaft 167 (e.g., via a bearing component of the hand crank support assembly 165). A hand crank sprocket 166 is coupled to one end of the hand crank driveshaft 167, and engages a second spool sprocket 62 coupled to one of the spool endplates 20. A lever (not shown) may be removably coupled to the other end of the hand crank driveshaft 167 to allow a user to rotate the driveshaft 167 and, thereby, cause the spool assembly 10 to rotate relative to the support assembly 110.
a is a perspective view of one embodiment of the support assembly 110, comprising two substantially similar opposing support endplates 120.
In the embodiment illustrated by
Although not shown in the figures, the support assembly 110 may comprise various other apertures or structures such as structures for mounting the support assembly to a vehicle, a floor, the ground, a wall, a ceiling, a set of wheels, etc. Such structures may be molded into the support assembly 110 or may be separate structures that can be attached to the support endplates 120 or support endplate connecting members 130.
a is a perspective view of one embodiment of the spool assembly 10, comprising two substantially similar opposing spool endplates 20, coupled together by at least one, or a plurality, of elongate spool endplate connecting members 30.
The spool endplates 20 may also define apertures 23 for fastening the axles 40 and 41 to the spool endplates 20. In addition, the spool endplates 20 may further define a circular aperture 42 disposed about the center of the endplates 20 so that the axles 40 and 41 may pass therethrough. The apertures 42 may also be used to pass a pipe, hose, or cable therethrough as an extension or connection from one end of the hose, cord, or cable wound on the spool assembly 10, to one end of an external hose, cord, or cable. In instances where the reel 1 is configured for storing a hose, one of the axles 41 may comprise a pipe 50 used to connect one end of the hose wound on the reel 1 to one end of an external hose or pipe. In one embodiment, the end of the pipe 52 that extends out from the support assembly 110 may comprises a rotatable coupling for removably attaching an external hose or pipe to the end of the pipe 52 so that, when the axle 41 rotates with the spool assembly 10, the external hose or pipe connected to the end 52 of the pipe is not also required to rotate. If the reel 1 is configured for storing electrical or other cable, the reel 1 may comprise a cable extension having the appropriate connectors. In some embodiments, however, no such extension or connector is implemented, and the cord or cable is simply wound about the spool assembly 10.
The spool endplates 20 further define apertures 22 for connecting the spool endplate connecting members 30 to the spool endplates 20. The apertures 22 are spaced about the spool endplate 20, in some instances at equal distances from the center of the spool endplate 20, so that when the spool endplate connecting members 30 are engaged with the apertures 22, the spool endplate connecting members 30 cooperate to define a support structure for supporting the hose, cord, or cable. Although not shown in the figures, the spool endplates 20 may further define other apertures that cooperate to define generally concentric perimeters with respect to the perimeter defined by the illustrated apertures 22. These additional apertures could also be used for connecting the spool endplate connecting members 30 to the spool endplates 20. Such a configuration may allow the dimensions of the support surface to be appropriately varied by moving the spool endplate connecting members 30 from one set of the apertures 22 to another set of concentric apertures defined by the spool endplates 20. In one embodiment, the apertures 22 are used both to connect the spool endplate connecting members 30 and the sprockets 60 and 62 of the drive mechanism to the spool endplates 20. The details of such a connection are described in greater detail below in accordance with one embodiment of the invention. In another embodiment (not shown), other apertures or structures are defined by the spool endplates 20 for attaching the sprockets 60 and 62 or other items to the spool endplates 20.
In some instances, the spool endplates 20 may further comprise at least one circular step portion 21 that extends inwardly toward the center of the spool assembly 10. These step portions 21 may function, for example, to partially support at least a portion of the wound hose, cord, or cable. In addition, the outward face of the spool endplate 20 may define at least one recess 24. This recess 24 may provide, for instance, a space for receiving the sprocket 62 used in the hand crank drive system. If a motor-driven drive system is used in the reel 1, spacers 25 may be used for separating the sprocket 61 from the side of the spool endplate 20 to allow sufficient room for the chain 65 to pass over the sprocket 60 and around the motor sprocket 161. Such steps and recesses may further add structural integrity to the spool endplates 20. In other embodiments, however, the spool endplates 20 do not have any step or recess.
a is an illustration of an exemplary embodiment of an endplate connecting member 230, such as that which can be used as a spool endplate connecting members 30 and/or a support endplate connecting members 130. The connecting member 230 is elongate with opposed ends. In some instances, the connecting member 230 may be cylindrical. The connecting member 230 may be, for example, a solid member or a hollow tube, and made of any material suitable for application to the support and/or spool assemblies 110, 10. In one embodiment, the connecting members 230 may be comprised of hollow metal tubing or pipe such as steel tubing, and may be plated, painted, or otherwise coated or treated to improve the corrosion resistance thereof. Such connecting members 230 are configured to extend between the support or spool endplates 120, 20, as appropriate, so as to couple the respective endplates together. In some instances, each connecting member 230 comprises two defined connecting elements disposed about the ends thereof, with the connecting elements being separated by an elongate medial portion 232. The separation distance W between the defined connecting elements determines the width W1 of the support assembly or the width W2 of the spool assembly.
The connecting elements may comprise, for example, threaded end portions 231 of the connecting member 230, wherein the threaded end portions 231 may be configured to operably engage a complementary threaded securing member 240.
d illustrates a cross-sectional view of two endplate connecting members 230 coupled to a support endplate 120 using securing members 240, according to one embodiment of the present invention. The apertures 122 defined by the support endplate 120 are configured to receive the tubular portion 242 of the securing member 240 such that the head portion 241 of the securing member 240 abuts the support endplate 120 when securing member 240 is screwed onto the threaded end 231 of the connecting member 230. The diameter of the threaded end 231 of the connecting member 230 is less than the diameter of the medial portion 232 so that a washer 250 may be disposed about the threaded end 231, without being movable over the medial portion 232 of the connecting member 230. In this manner, when the securing member 240 is screwed onto the end 231 of the endplate connecting member 230, the support endplate 120 is secured between the washer 250 and the head portion 241 of the securing member 240. In other embodiments, the diameter of the threaded portion 231 of connecting member 230 may be sufficiently less than the diameter of the medial portion 232 such that a washer 250 may not be necessary. The spool endplate connecting members 30 may be coupled to the spool endplates 20 in a similar manner to that disclosed herein with reference to the support assembly 110.
e is a perspective view of a support assembly 110 utilizing the endplate connecting members 230, securing members 240, and washers 250 to connect the two support endplates 120, according to one embodiment of the present invention. The spool assembly 10 can be formed in a similar manner using endplate connecting members 230, securing members 240, and washers 250. As can be seen in the figures, the length W of the medial portion 232 of the connecting members 230 generally determines the distance W1 or W2 between the support endplates 120 or spool endplates 20, respectively.
One skilled in the art will thus appreciate that embodiments of the present invention facilitates adjustability of the width of the support assembly 110 and/or the spool assembly 10, by changing the connecting members 230, as appropriate. That is, various sets of connecting members 230 may be formed, with each set having a different length W of the medial portion 232 between the threaded end portions 231 of the connecting member 230, whereby the width of the support and/or spool assemblies 110, 10 can be readily varied to meet the requirements of a particular application. This adjustability may be advantageous since the support assembly 110 can be readily adjusted to suit mounting constraints and support needs, while the spool assembly 10 can be readily adjusted to suit size constraints and spool capacity needs. Similarly, for instance, the material used for the connecting members 230 or the gauge of the connecting members 230 may be varied depending upon the strength requirements or weight constraints for the reel 1. Thus, the reel 1 can be readily customized by changing the connecting members 230.
a and 5b illustrate another exemplary embodiment of an endplate, where one or more tubular inserts 246 are associated with one or more of the apertures 122 to provide, for example, greater strength and rigidity of the reel assembly 1 by reinforcing the endplate 120 about the apertures 122. The tubular inserts 246 may be made from a metallic material, such as aluminum. For instance, the tubular inserts 246 may be cut from hollow metal tubing or pipe, such as aluminum tubing. The tubular inserts 246 comprise an outside diameter and an inside diameter. Preferably, the outside diameter is such that the insert 246 fits snugly within the aperture 122 defined by the endplate 120, and the inside diameter is such that the connecting member 230 fits snugly within the tubular insert 246.
For example,
In one embodiment, the tubular inserts 246 are molded into the polymeric endplates 120 at the time the endplates 120 are molded. In such an embodiment, the molded-in inserts 246 define the endplate apertures 122 configured to receive the ends of the support endplate connecting members 130 for connecting the support endplate connecting members 130 to the support endplates 120. Although
One skilled in the art will thus appreciate that embodiments of the present invention provide an improved reel that may provide a strong, durable, corrosion resistant, lightweight, modular and customizable reel that is relatively easy to manufacture and assemble. For example, according to one embodiment of the present invention, a supply of substantially similar polymeric spool endplates can be made from a first mold and a supply of substantially similar polymeric support endplates can be made from a second mold, with both supplies of endplates being manufactured with a single rotomolding machine. A supply of substantially similar endplate connecting members, varying in length (and/or width), can also be manufactured for use as spool endplate connecting members 30 and/or support endplate connecting members 130.
