BACKGROUND
The beverage industry often utilizes reusable and refillable cylindrical containers to hold, and oftentimes dispense, its contents. One example of such a containers is the beer keg, which is often filled with new contents at the site of the bottling or brewing company, loaded onto trucks, and taken to their retail destination. Empty and returned kegs are also retrieved and returned to the beverage company for cleaning and refilling.
Kegs, regardless of the material from which they are made, are often heavy, especially when filled. As such, it is convenient, if not necessary, that the containers be stacked on top of one another to allow the greatest number of containers to be safely stored in the smallest amount of space, whether in transporting the containers, storing the containers at the generation point, or holding the containers at the retail destination. To that end, the keg stacking device allows for the safe stacking of keg containers and the like without having to modify the kegs.
As used herein, “keg” refers to any generally cylindrically-shaped container or vessel for storing and/or shipping water and other liquids, including beer as well as other assorted beverages and fluids such as chemicals, paints, and the like, including combinations thereof. Such kegs can be made of any material commonly used in the art, including metal, resin, carbon fiber and plastic.

Referring now to the drawings, FIG. 1 shows a top perspective view of one embodiment of keg stacking device 100. In the embodiment shown, keg stacking device 100 is comprised of horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128, vertical bars 131, 132, 133, and 134, and locking members 140. Horizontal bars 121, 122, 123, and 124 are each parallel to one another. Horizontal bars 125, 126, 127, and 128 are also each parallel to one another. And vertical bars are all positioned 131, 132, 133, and 134. Horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128 and vertical bars 131, 132, 133, and 134 meet at locking members 140 (described in detailed infra) at right angle, forming a substantially cubic structure. Horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128, vertical bars 131, 132, 133, and 134, and locking members 140 are joined using MIG welding. However, it should be understood that any other means can be employed, including but not limited to TIG welding, arc welding, interlocking members, adhesives, and constructing keg stacking device 100 as a single integrated unit.
In the embodiment shown in FIG. 1, horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128, vertical bars 131, 132, 133, and 134, and locking members 140 are all made of mid steel. However, it should be understood that any alternate material having sufficient strength and durability to support a keg (not shown) can be used, including by not limited to aluminum, high density plastic, resin, carbon fiber, and composites or combinations thereof.
FIG. 2 shows a top perspective view of one embodiment of locking member 140 used in the embodiment of keg stacking device 100 shown in FIG. 1. The particular locking member 140 shown in FIG. 2 is at the meeting point of horizontal bars 121, 126 and vertical bar 134. Locking member 140 is comprised of vertical portion 141, horizontal portion 142 (collectively making up a locking member base), aperture 143, and adjustable keg engaging member 144. Horizontal bars 121, 126 are welded (as provided supra) to vertical portion 141, and vertical bar 134 is welded to the underside of horizontal portion 142. Horizontal portion 141 and vertical portion 142 are made of one (1) component and bent at 145, but could alternatively be made of two (2) separate pieces welded or otherwise connected. Vertical portion 141 is further comprised of aperture 143 through which adjustable keg engaging member 144 is positioned. Adjustable keg engaging member 144 has threads disposed thereon, allowing the lateral position of adjustable keg engaging member 144 to be changed, thus allowing each adjustable keg engaging member 144 to be secured to the keg (shown and described infra with respect to FIG. 3). In the embodiment shown, adjustable keg engaging member 144 is a thumb screw, but alternate embodiments of adjustable keg engaging member 144 can be any type of screw that allows its position to be laterally altered, including but not limited to license plate bolts and a threaded eye bolt. In addition, one of ordinary skill in the art will recognize that another type of locking member 140 can be employed with keg stacking device 100 as long as it is sufficiently strong, compatible with the materials of the other components, and temporarily locks the keg in position.
FIG. 3 shows a cross-sectional side view of the embodiment of keg stacking device 100 shown in FIG. 1 in use with two (2) kegs 50, 52, both shown in broken lines. Keg 50 includes neck 51, and keg 52 includes neck 53. As can be appreciated keg stacking device 100 engaging neck 51 on one (1) end and neck 53 on a second end. Each thumb screw 144 is tightened until its forward end extends laterally a sufficient length to engage neck 51, 53. Keg stacking device 100 thus allows keg 52 to be safely and stably placed on top of keg 50. It should be understood that the embodiment of locking members 140 shown in FIG. 3 are only one (1) embodiment. Alternate types of locking members that temporarily lock kegs 50, 52 in place relative to keg stacking device 100 and one another can also be used.
FIG. 4 shows a top perspective view of an alternate embodiment of keg stacking device 100, further including adjusting members 150. In the embodiment shown, adjustment members 150 are positioned on horizontal bars 125, 126, 127, and 128 and allow keg stacking device 100 to be sized to work with different sized kegs (not shown). In the embodiment shown, adjustment members are turnbuckles and made of aluminum. Horizontal bars 125, 126, 127, and 128 threadedly engage adjustment members 150 with reverse threading such that as each adjustment member 150 is rotated (as designated by arrows 151), the total length of each horizontal bar 125, 126, 127, and 128 can be changed. It should be understood, however, that alternate adjustment members 150 could be used or could be made of alternate materials. In addition, adjustment members 150 could also be positioned on horizontal bars 121, 122, 123, and 124 and/or on vertical bars 131, 132, 133, and 134, either instead of or in addition to adjustment members 150 shown on horizontal bars 125, 126, 127, and 128, which would allow keg stacking device 100 to be adjustable in an X, Y, and/or Z direction.
In an alternate embodiment of keg stacking device 100, adjustment members 150 are instead comprised of one (1) portion of horizontal bars 121, 122, 123, 124, 125, 126, 127, 128 and/or vertical bars 131, 132, 133, and 134 are instead formed of two (2) members, a male portion and a female portion, both of which include a series of equally spaced apertures. In such an embodiment, the length of each horizontal bar 121, 122, 123, 124, 125, 126, 127, 128 and/or vertical bars 131, 132, 133, and 134 can be adjusted. The holes allow a pin to be put through both the male and female end to lock horizontal bars 121, 122, 123, 124, 125, 126, 127, 128 and/or vertical bars 131, 132, 133, and 134 at a fixed and adjustable length.
In addition, each embodiment shown in the Figures and described herein is made only of metal. It should be understood that alternate embodiments of keg stacking device 100 can alternatively be coated with rubber (or similar material) or can include pads positioned on some or all of horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128. Such protective members prevent metal-to-metal contact between keg stacking device 100 and the kegs (not shown) which can damage either. In addition, the embodiment of keg stacking device 100 is shown as having a total of twelve (12) bars. It should be understood that additional bars, vertical or horizontal could be included, creating a stronger keg stacking device 100 and/or allowing less robust horizontal bars 121, 122, 123, 124, 125, 126, 127, and 128 and/or vertical bars 131, 132, 133, and 134, herein referred to as additional support members. Other embodiments may contain more, fewer, or differently shaped or configured support members.
While keg stacking device 100 has been shown and described with respect to several embodiments and used in accordance with the present invention, it is to be understood that the same is not limited thereto, but is susceptible to numerous changes and modifications as known to a person of ordinary skill in the art, and it is intended that the present invention not be limited to the details shown and described herein, but rather cover all such changes and modifications obvious to one of ordinary skill in the art.
