1. Field of the Invention
This invention relates generally to stowage racks, and more particularly to stackable stowage racks that may be used for wheeled utility carts.
2. Related Art
Non-motorized wheeled utility carts are commonly used for transporting product from one place to another. A need to move large quantities of product on a regular basis typically requires a relatively large stock of utility carts. Unfortunately, having a large stock of utility carts requires a relatively large amount of space to stow the carts. Typically, the carts are stowed side-by-side at ground level, thereby occupying a maximum amount of valuable floor space, which can be costly and inefficient.
A stackable rack for stowing utility carts having a plurality of wheels may include a deck surface on which a plurality of utility carts may be at least partially received and a wheel stop surface adapted to engage a wheel on the utility carts to inhibit rolling movement of the utility carts. The rack may also include a plurality of support rails extending above the deck surface, a first locator carried by at least one of the support rails and adapted to facilitate positioning a separate stowage rack on top of said stowage rack, and a second locator adapted to communicate with a first locator of another stowage rack to facilitate positioning said stowage rack above another stowage rack. Accordingly, several wheeled carts can be releasably retained on the rack, and several racks can be stacked one on top of another to permit stowing a plurality of carts in a relatively small floor space or area.
According to a method of stowing wheeled utility carts, a plurality of stackable racks are provided with each having a deck surface and a plurality of support rails extending from said deck surface wherein the deck surface has a wheel stop surface adapted to engage a wheel on the utility carts to inhibit the utility carts from rolling movement along the deck surface. A predetermined number of utility carts are loaded onto the deck surface to bring the wheel on each of the carts into engagement with the wheel stop surface, and a fully loaded one of the racks is stacked on top of another rack.
Some of the objects, features, and advantages of the invention will become readily apparent in view of the following detailed description of presently preferred embodiments and the best mode, appended claims and accompanying drawings, in which:
Referring in more detail to the drawings,
As shown in
The stowage rack 10 has a generally flat deck or deck surface 24 for supporting the carts 12 thereon. The deck surface 24 is represented as being generally rectangular, for example, though it could take on other shapes, with a width extending between opposite sides 26, such as to accommodate five carts arranged in side-by-side relation, for example, and having a length extending between front and rear ends 27, 28 sufficient to accommodate the length of the carts 12. The deck surface 24 is represented here, for example, as being supported on a horizontal peripheral frame. The frame has horizontally extending front and rear supports 29, 30, defining in part the front and rear ends 27, 28 of the rack 12, with horizontally extending side supports 32 extending between the front and rear supports 29, 30. As shown in
By way of examples, the deck surface 24 can be formed from individual strips of material laid side-by-side and resting in between or on the side supports 32 and cross supports 34, or the deck surface could be formed from wider planks or sheets of material that cover all or any portion of the total deck surface with a slot, recess or the like defining the gap 36. The deck surface material may be retained on the supports 32, 34 or otherwise carried by the frame in any suitable way, including, by way of examples without limitation, fasteners, welding, interlocking or overlapped members and adhesion.
As best shown in
The rack 10 has a plurality of support rails 40 extending upwardly from the deck surface 24, represented here, by way of example and without limitations, as defining a pair of front and rear comers of the rack 10. The support rails 40 may extend a predetermined distance upwardly to support an overlying rack 10 at a sufficient height to allow the upstanding handles 18 of the stowed carts 12 resting on the underlying rack 10 to be freely received beneath the deck surface 24 of the overlying rack 10. The support rails 40 are preferably braced to one another via a cross brace to add strength and rigidity to the rack 10. For example, the rear support rails 40 are braced to one another by a horizontally extending upper support or cross brace 42 and a pair of crisscrossed supports or braces 43 extending between the upper cross brace 42 and the deck surface 24; and the rear support rails 40 and a corresponding one of the front support rails 40 on the same side 26 of the deck surface 24 are braced to one another by a horizontally extending upper support or cross brace 44 and a pair of crisscrossed supports or braces 45 extending between the upper cross brace 44 and the deck surface 24.
As such, three sides (the sides 26 of the rack 10 and the rear end 28 of the rack 10) are at least partially closed-off by the corresponding crisscrossed braces 45, 43, and thus, in addition to providing added support to the support rails 40, the braces 43, 45 can act to retain the carts 12 on the rack 10 by preventing movement of the carts through these three sides. The front upright support rails 40 are preferably braced to one another by a horizontally extending upper support or cross brace 46 that is spaced a sufficient distance from the deck surface 24 to allow the upright handles 18 to pass freely there under when the carts 12 are being loaded on the rack 10 such that the front side of the rack is open to permit the carts to be loaded into and unloaded from the rack through the front side. In the implementation shown, the upper cross brace 46 is spaced further from the deck surface 24 than the other upper braces 42, 44 which may be located to engage the cart handles 18. Other retainers or support members may be provided to engage and retain a desired portion of a cart if, for example, upstanding handles like those shown at 18 are not provided at each end of the cart. For example, a cart may have a handle at only one end, and it may be desirable to provide a retainer to engage the end of the cart without a handle to more reliably retain the carts and to permit the carts to be loaded on the racks 10 with either end leading.
The upright support rails 40 are preferably equal in height to facilitate supporting an overlying rack 10 in a level orientation. Each of the support rails 40 may have a first locator and a second locator at opposite ends of the rails. One of the locators, represented here as a first or upper locator 48, is generally funnel shaped and may include an opening, while the other locator, represented here as a second or lower locator 50, is generally cylindrically shaped and adapted to be received in the opening of a first locator. The funnel shaped upper locators 48 extend upwardly from one end of the support rails 40, while the lower locators 50 extend downwardly from the other end of the support rails 40 below the deck surface 24. Each upper locator 48 of an underlying rack 10 is adapted to receive a corresponding lower locator 50 of an overlying rack 10 to facilitate stacking and maintaining the racks 10 in a secure and stationary position relative to one another. The funnel shape of the upper locators 48 facilitates guiding the lower locators 50 for receipt therein. The respective locators 48, 50 can be formed as one piece with the support rails 40, or they can be attached thereto, such as by fasteners or a weld joint, for example. It should be recognized that the locators 48, 50 could extend from a location on the racks other than the support rails 40, and that their shapes could be altered or swapped, if desired.
To facilitate moving or stacking the racks 10, a pair of fork guide members 52 can be provided. As shown in

In use, the carts 12 are simply wheeled onto the deck surface 24, 62 of the respective rack 10, 60 until the associated wheels 20, 22 are received in the respective gaps 36, 64, 66 in the deck surface 24, 62, whether center wheels 22 on the six-wheeled cart 12 or at least one pair of the front or rear wheels on the four wheeled cart, as discussed above. If only four-wheeled carts are being stowed, then the rack 60 as discussed in association with
It should be recognized that upon reading the disclosure herein, that one ordinarily skilled in the art of would readily recognize other embodiments than those disclosed herein, with those embodiments being within the spirit and scope of the invention. For example, rather than the wheel stop surface being formed via the gap, it could be formed via one or more protrusions that may be integral with or carried by or on the deck surface, a recess or concavity, or other suitable arrangement to releasably retain or restrain the carts to at least inhibit, and preferably prohibit, the carts from unintentionally or accidentally rolling or moving out of a rack. Further, while the gaps 36, 64, 66 shown in the drawings are elongated and continuous, a plurality of discrete gaps, openings, protrusions, or other wheel stop surfaces may be provided along the deck surface or frame of the rack. Accordingly, the disclosure herein is intended to be exemplary, and not limiting. The scope of the invention is defined by the following claims.
This application claims the priority of U.S. Application No. 60/713,580, filed Sep. 1, 2005, the complete disclosure of which is hereby incorporated by reference.
