The invention relates most generally to barrel racks, and more particularly to wine barrel racks, and still more particularly to a compact, nestable, and economically transportable wine barrel rack system having discrete barrel cradle assemblies for stacking either identically or differentially sized barrels in a staggered stacking configuration, while providing access to barrel bungs at all levels. In some stacking configurations, seismic stability can be enhanced with seismic straps.
In wine production, when fermentation has been completed and after large solids have been removed by racking, the young wine usually needs time for the acids, alcohol, tannins, and glycerin to knit together, to harmonize. Accordingly, it is a traditional practice to barrel age and store the wine for a period of time. This can be accomplished using a number of different kinds of vessels or containers, such as stainless steel tanks, cement vats, glass carboys, or, in most instances, wood barrels. The traditional wood barrel material is oak (indeed, nearly all fine wines, almost without exception, are aged in oak) because it adds depth and complexity by adding phenols and oak tannins to the wine, and thereby adds new bouquet and flavor dimensions. Aging in oak also softens grape tannins, increases volatile acidity and total acidity, and lowers pH. Stored the right amount of time, wine aged in oak barrels is generally considered to be improved.
In consequence, large scale producers often keep hundreds to many tens of thousands of barrels in storage in production and storage facilities, generally either in barrel rooms or wine caves. The racks, however, cover a considerable amount of floor space. Furthermore, they are generally assembled by welding square steel tubing with steel bars to make unitary, assembled, rigid and fixed racks of the kind taught by Ray, U.S. Pat. No. 3,476,260, which shows a wine rack design that dominates the industry at present. See, for instance, the various models offered at the website links by the following major current-day manufacturers:

From these, it will be seen that the rack dominant in the industry is a rigid square steel tube welded structure based on structural chocks welded onto square tube steel frame structure. The tube members are all welded together, and the bent steel bars forming wedges that act as chock are welded onto the tubes. The smallest units for stacking systems generally hold two barrels and stack atop two barrels. Bottom units simply cradle two barrels on top. Even this smallest structure consumes considerable space when assembled and welded, and thus when shipped. And stacking for shipment simply means that a substantial portion of the shipping volume is occupied by empty space.
As the South Napa Earthquake of Aug. 24, 2014 revealed, when racks are severely damaged in earthquakes, they are not amenable to repair and generally must be replaced. Fabrication of the conventional and traditional racks is time consuming and shipments are expensive. High demand taxes the ability of manufacturers to meet winery schedules for the needed stackable, palletized and forklift compatible barrel racks. In the years immediately following the South Napa Earthquake, there were many shipments of replacement racks required to address the losses. Among other things, that earthquake highlighted the need for a more compact rack, easily manufactured, easily and economically transported, and also easily dismantled for removal and relocation.
The present invention solves several subsisting problems, including the foregoing problems, by providing a low cost, easily manufactured, easily transported, and easily on-site assembled barrel rack that includes nesting component parts that ship in compact packages.
The wine barrel rack of the present invention advantageously exploits known principles of strengthening thin sheet metal panels by introducing bends and cutouts in the panels. Thus, the barrel support function of what was previously provided by a very heavy and clumsy structure—rigid, unitary, preassembled square tubular steel wine barrel racks—can now be provided by extremely lightweight structural members that can be shipped as modular packages, easily handled, carried, and moved by individuals having unexceptional (entirely ordinary) strength.
In an embodiment, the disclosed wine barrel rack system includes first and second ground level side rails oriented generally parallel to one another. The side rails are joined to one another with either sheet metal panel connecting members or tubular metal connecting members, the latter having bolting plates or flanges disposed on their ends. The rack is assembled with nuts and bolts. Each of the side rails include an upper bend forming a flange and a lower bend forming a flange so as to enhance the strength of the panels. In an embodiment, barrel shaped cutouts are disposed on the upper edge of the side rails in a ground configuration of the rack, and on both upper and lower edges in an upper rack configuration. The cutouts may provide for barrel stacking in a generally stacked pattern, in which case upper cutouts in rails at upper levels are positioned generally directly above cutouts in the ground level rails and/or any other lower level of stacked barrels. They may also be configured for stacking in a staggered pattern.
In another embodiment, elongate tubular steel members span laterally between side rails and include bolting plates or flanges on each of their ends. The bolting plates are coupled to the side rails in an angled orientation to form a cradle. Rubber support pads are slotted to fit over the bolting plate edges to cushion the cradle and distribute the barrel load. In this embodiment, barrels in upper rows may be supported by barrel-specific (discrete) arcuate cradles that may be coupled or linked with chain or cable. Seismic tie downs may be employed to connect to a frame disposed over barrel bung holes so as to keep wine stored in the barrels entirely accessible even in the seismically secure, stacked storage configurations.
The invention will be better understood and objects and advantages other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings, wherein:
Referring first to
Looking now at
Thus, it is seen that each ground level side rail 12/14 includes a plurality of upper arcuate cut outs 22, each suitable for supporting or cradling a wine barrel when paired with a cutout on the opposing side rail, as shown in
Each side rail further includes an outwardly directed lower bend or flange 24, and an outwardly directed upper bend or flange 26, continuous but for interruptions at the upper arcuate cutouts, and thereby comprising a formed sheet.
The connecting panels 16/18/20 are each U-shaped with end legs 28 and through holes 30 that align with through holes 32 in the side rails for connection with nuts and bolts 34, 36, respectively. Washers 38 are preferably employed, for all the well-known reasons.
It will be noted, by reference to each of
The barrel rack system has distinct manufacturing advantages over the known art. This derives from the simplicity, rapidity, and economically advantageous method of manufacture. Because they are formed of sheet metal, and because the manufacturing process includes only a few quick fabrication steps, the barrel racks can be rapidly manufactured on demand, and therefore no appreciable inventory need be stored anywhere.
Connecting panels 16, 18, 20 are formed from a separate raw sheet of sheet metal, and then drilled and bent similarly.
The stackable rack 60 includes first and second side rails 62, 62 joined at their ends 62a/62b and 64a/64b, respectively, by first and second connecting end panels 66, 68, and a medial connecting panel 70. The side rails are identical to one another, as are the connecting panels.
Each stackable side rail 62/64 includes a plurality of arcuate cut outs 72, each suitable for supporting or cradling a wine barrel when paired with a cutout on the opposing side rail, as shown in
As with the first embodiment, U-shaped connecting panels 66/68/70 again include legs 78 and through holes 80 that align with through holes 82 in the side rails for connection with nuts 84, bolts 86, and washers 88.
Forklift holes 90 may be provided in the side rails.
The rack elements are each preferably formed from stainless steel, and more preferably with 300 series austenitic stainless steel, though any of a number of kinds of stainless steel and aluminum panel kinds may be employed to provide a rack with sufficient structural integrity and corrosion resistance to handle the heavy loads borne by racks in which barrels are stacked 4 or more levels high in slightly acid and humid cellar environments.
The stackable rack is also capable of compact storage in nestable packs 100, thus making it fit for large shipping unassembled in large numbers so as to be able to meet the needs of an end user at low cost and in quick order.
In another embodiment of the present invention, shown in
Thus, it is seen that each ground level side rail 202/204 includes a plurality of arcuate cut outs 216, each suitable for supporting or cradling a wine barrel when paired with a cutout on the opposing side rail, as shown in
Each side rail further includes an outwardly directed lower bend or flange 218, and an outwardly directed upper bend or flange 220, continuous but for interruptions at the arcuate cutouts, and thereby comprising a formed sheet.
The end cross members 210/212 and medial cross members 214 are each fabricated from square or rectangular tube (steel, aluminum, alloys, etc.) with an integral and/or welded flange 222 and through holes that align with through holes in the side rails for connection with nuts and bolts 224, respectively, the holes concealed by the nut/bolts assemblies, but evident in the views. The cross members for the ground level configuration further include legs 226 to elevate the entire rack off the ground and provide clearance for water and wine to run freely out from under the assembly and for the forks of a forklift to fit under easily for easy and rapid movement of entire racks within a production facility.
This embodiment of the wine barrel rack of the present invention includes an enhanced cutout having notches 228 onto which chocks 230 with slots are disposed so as to provide support and cushioning in the arcuate cradle formed by the cutouts 216. The chocks are fabricated from a food grade resilient material, such as silicone or other suitable synthetic rubber product, so as to minimize any chance that the assembly will harbor microorganisms that might infect and destroy the beverage contained in the barrels.
Cross members 210, 212, 214 are formed from separate metal tubes and then drilled and provided with flanges.
The upper (stackable) rack 250 is configured substantially identically to the ground level configuration with a few notable exceptions, clearly seen in
Thus, it is seen that in this embodiment each upper rack side rail 252/254 includes a plurality of upper and lower arcuate cut outs 266a and 266b, respectively, the upper arcuate cut outs adapted for supporting or cradling a wine barrel and bearing its weight, and the lower cut outs 266b adapted for placement over a wine barrel. The upper and lower cutouts are arranged in a staggered pattern, such that the lower cutouts re disposed under and generally centered between two adjoining upper cutouts.
Each side rail further includes an outwardly directed lower bend or flange 268, and an outwardly directed upper bend or flange 270, continuous but for interruptions at the arcuate cutouts, and thereby comprising a formed sheet.
The end cross members 260/262 and medial cross members 264 may be fabricated from square or rectangular tube (steel, aluminum, alloys, etc.) with an integral and/or welded flange 272 and through holes that align with through holes in the side rails for connection with nuts and bolts 274, respectively, the holes concealed by the nut/bolts assemblies, but evident in the views. The cross members for the upper rack configuration do not include legs to elevate the rack off the ground, as clearance for water and wine, for the forks of a forklift, and the like, is inherent in the elevated disposition of the rack when placed atop a wine barrel.
This embodiment of the wine barrel rack of the present invention also includes the enhanced cutout having notches 278 onto which upper chocks 280a and lower chocks 280b, each with slots, are disposed. Again, these provide support and cushioning in the arcuate cradle formed by the cutouts 266a/266b.
Cross members 260, 262, and 264 are formed from separate metal tubes and then drilled and provided with flanges.
In further embodiments of the present invention, shown in
Each side rail also further includes an outwardly directed lower bend or flange 410, and an outwardly directed upper bend or flange 412, continuous but for interruptions at the cutouts, and thereby comprising a formed sheet.
The cross members 406 for use in this embodiment are each fabricated from square or rectangular tube 414 with an integral and/or welded bolting plate or flange 416 and through holes 418 that align with through holes in the side rails 420 for connection with nuts and bolts 422. Solid steel or aluminum blocks are cut to accommodate the flange and panel of the side rail and to bolt onto the side rails and thereby to act as legs 424 that elevate the side rail slightly above ground level, again, providing clearance for water and wine to run freely out from under the assembly and for the forks of a forklift to fit under for easy and rapid movement of loaded racks.
As indicated above, the side rail cutouts may be any of a number of shapes, including arcuate (as in an earlier embodiment) or more polygonal in side view. In a preferred embodiment, the region of the side rail cutout may include inwardly angled mounting tongues 426 having an upper edge 427 and proximate an outer edge 428. A slotted food grade resilient mounting pad or chock 430 is placed on the tongue. Moreover, the tongue is spaced apart slightly from the cutout outer edge so as to allow some compression of the chock when under load from a barrel. From the views it will be seen that in an embodiment, the edge of the bolting plate 416 may be oriented and generally aligned with the tongue when the cross member bolt holes 418 are brought into alignment with the side rail bolt holes 420. The chocks comprise a food grade rubber, synthetic rubber, or polymeric block 432 with a slot 434 for placement over the tongue upper edge 427 or the bolting plate or a combination of the tongue and bolting plate (see further at
As can be seen by reference to
Thus, and still referring to
While many, if not most, wine producers may use barrels of identical size and construction for wine storage, barrels are handmade and inherently imperfectly sized. Further, some winemakers may wish to experiment with different barrels from different coopers. The rigid rails systems of the above-described embodiments are not perfectly adapted for use on rows of barrels that include any barrel departing from the size of adjoining barrels. Thus, and referring now to
Each cradle 500 includes identical opposing substantially planar metal wedge plates 502 joined by cross members 406 identical to those employed in the ground rail assembly. In an embodiment the wedge plates comprise an elongate shape having mirror image first and second ends 504, 506 configured with upper and lower angled mounting tongues 508, 510, and 512, 514, respectively, at their ends, and each having an edge 508a, 510a, 512a, 514a generally in line with the respective upper edge 516 and lower edge 518 of the wedge plate. The mounting tongues may be defined by slots cut into the upper and lower edges of the wedge plate. The arcuate shape includes an upper edge radius slightly larger than the radius of a standard 60-gallon wine barrel or a 53-gallon whiskey barrel between the quarter hoop and head hoop circumferences. A resilient mounting chock 430 may be disposed on the edges of each tongue so as to cushion barrels above and below (see
In an alternative embodiment of the cross member 440, an upper side 442 of the bolting plate 444 may be elongated so as to obviate the need for a tongue in either the ground level side rails or the wedge plates, such that the elongated upper side 442 functions as the barrel support structure (see
In still another embodiment, cross member 440 may include a bolting plate or flange having both an elongated upper side 442 and an elongated lower side 446, thereby obviating the need for a tongue on either the upper side or the lower side of the wedge plate.
Those with skill will appreciate that after transport in a nested configuration, the barrel rack of the present invention may be assembled using welds rather than using a nut-and-bolt assembly. The advantage of a potential rapid disassembly or reconfiguration is lost in such a case, but there is the concomitant advantage gained through the elimination of self-loosening nuts and bolt connections.
As will be appreciated from reference again to
Thus, it is seen that in embodiments, each upper cradle is adapted for resting on barrels in a lower course (whether ground level or above) and for supporting or cradling a wine barrel and bearing its weight. As with the embodiment using an upper rail configuration, the ground level rail and discrete cradle arrangement provides a staggered stacking pattern.
