This invention is directed towards an equipment support device which may be in the form of a conical foot that is designed to support and elevate equipment above a floor or work surface. The foot support is particularly useful for ferrous objects that might rust when in contact with a damp floor or could be exposed to liquids during floor maintenance and cleaning operations.
It is known in the art to elevate equipment, materials, and product inventory above a floors surface, Various types of permanent or temporary shelving, racks, and the use of wooden blacks or plastic foots are frequently used to elevate large or heavy items when stored on the floor. In some instances, the support feet are permanently attached to the supported item. In other instances, the foots or support items are not secured to either the equipment or the floor and may be inadvertently moved or in an improper location when an item is being positioned or repositioned. In many instances, wood blocks and pallets that might be used to elevate an item tend to generate wood scraps which negatively affect the cleanliness and safety of the work environment. Additionally, wood surfaces will often chemically react with the surface of a supported metal component. For metals that may be subjected to a subsequent and anoclization process, painting or powder coating, the chemical reaction may render the metal surface unsuitable for such coatings and processes.
Additionally, wooden supports are typically not secured to the supported metal objects so movement of the objects from one position to another requires removing the wooden blocks from one location and requiring a separate step of placing new blocks at a new, repositioned location. Accordingly, there is room for variation and improvement in the art.

The support foot 10, as seen in reference to
As seen in reference to
Around the perimeter of each foot 10 there are a plurality of circumferential cavities 40 defined within the foot 10. Along the top surface 10, each cavity 40 has a substantial semi-circular shape. As the foot tapers downwardly, the cross section of the cavity 40 increases and as the cavity 40 approaches the bottom surface 16, cavity 40 becomes nearly circular in shape.
A wall 50 connects an exterior wall of each cavity 40 to the central cavity 20 and extends along substantially the entire height of the respective walls of cavity 20 and a corresponding wall of cavity 40. As best seen in reference to
As seen in reference to
The arrangement of the corresponding parts described above describe a load bearing structure the strength of which is derived, in part, from the combination of multiple load bearing shapes and structures in a single combined foot structure.
The overall shape of the conical foot provides load bearing properties. Additionally, the center cylinder which defines the central cavity 20 provides a cylindrical loading bearing support. The outer perimeter cavities 40 each define a curved, open wall structure which is close to cylindrical shape along a bottom of foot 10 and tapers to a semi-circular hollow shape along a top 14 of the foot 10. The curved outer wall of each cavity 40 is contiguous with a portion of the cylinder wall 12, which also strengths the load bearing properties of the foot 10. The multiple walls 50 provide both compressive strength along a vertical direction of the foot and also help redistribute laterally to help distribute forces evenly along a width of the foot 10. The multiple collar regions 70 also provides for a large surface area to the top 14 to help in the distribution of forces to the wall 12 in the walls of the adjacent cavities 40.
The foot 10 uses an effective arrangement of physical structures, is lightweight, and offers excellent strength and compression characteristics. One suitable polymer that can be used is a co-polymer of polypropylene with about 10% to about 15% by weight of randomly oriented chopped glass fibers. The combination of the co-polymer of polypropylene and the glass fibers provides an end product that is not subject to cracking and sudden failure. Rather, if safety rating values or environmental conditions are exceeded, the polymer foot tends to bend and deform rather than undergo a catastrophic failure. This provides a margin of safety with respect to the support foot when used to support heavy items.
By way of a non-limiting example, the support foot can come in a variety of heights such as a 2 inch, 3 inch and 4 inch versions. For certain embodiments, a steel ring and male locator can be provided on the base of the units along with female locators on the top of the foot. This allows the user to stack a support foot on top of a larger foot that is designed to matingly engage. This allows the user to provide different support heights relative to the metal object and the support floor.
As seen in reference to the figures, a washer shaped magnet may fit within a diameter counter bore on the top of each foot allowing the foot to magnetically attach to the surface of any ferrous material. Located on the bottom of each foot may be another counter bore that contains a ferrous ring or magnet and thereby allows the foots to be stacked, one on top of the other, magnetically held together, or stored on a ferrous containing structure.
As further seen in reference to the figures, the foot forms an overall conical body that is supported by seven towers or cavities, six of the cavities being partially contiguous with an interior of the conical wall and a central cavity which, may in turn, be interconnected by a support arm to each of the six surrounding cavities. The upper surface of each of the support foots, including the cavities, may be open on the top and allow for a balanced and level support structure even when attached to a dirty or unclean surface.
When properly used, the support apparatus can keep ferrous materials and objects elevated off of a shop or tool house floor. This can assist in allowing a fork lift to have easy access to the underside of the supported object and at the same time keeps the object off the damp floors where corrosion or other damage could occur.
An alternative embodiment of the support foot can be seen in reference to
The cylindrical side wall 12′ tapers outwardly as the wall extends from the upper surface 14′ to the bottom surface 16′ of foot 10′. A plurality of circumferential edge walls 40′ are provided that have slit like openings along an upper edge as seen in
Ledge 22′, when threaded, will allow the use of a correspondingly mated insert to be secured thereto. The insert can support a smaller support foot or have a free end of the insert adapted for insertion and/or retention within an object to be supported.

The words used are words of description rather than of limitation. It is to be understood that changes and variations may be made by those of ordinary skill in the art without departing from the spirit or the scope of the present invention. In addition, it should be understood that aspects of the various embodiments may be interchanged, both in whole, or in part. Therefore, the spirit and scope of the invention should not be limited to the description of the preferred versions contained therein.
