Abstract
A foot for use on soft surfaces has a concave cavity facing downwardly from a mounting bracket. The foot may be used in combination with a cart, dolly, trailer, chair, table, stool, platform or the like.
Description
- The present invention relates to a foot for use to support an object on a soft granular surface such as sand. The foot is particularly well adapted to enable a chair, table, stool, platform, cart, dolly, trailer, or the like to sit on dry, fine, loose sand.
- Soft, granular surfaces, such as loose sand, pose problems to objects such as chairs, tables, stools, or anything with legs or leg-like supports. Conventional legs or leg-like supports tend to sink into these surfaces displacing sand outwardly causing a “boring,” “drilling” or “sinking in” effect in loose sand. This results in the object sinking into the sand creating the risk of it turning over and/or becoming contorted causing damage to the object.
- The present invention is directed to the problem posed to objects used on loose sand. The objects are not limited to but include outdoor furniture such as chairs, tables, stools, platforms, etc. or other objects such as carts, dollies, trailers utilizing trailer-jack type stands or the like. Legs on furniture items or support stands tend to sink down into the sand, especially if the associated furniture, structure, cart or dolly is supporting significant weight. Conventional attempts to overcome this problem generally involve the use of oversized flat plates to provide large surface areas contacting the sand in an attempt to preclude their sinking into the soft surface. While such large plates enjoy some success in supporting objects on loose materials, there is a cost or tradeoff associated with their increased size and in many cases the objects they are supporting must be modified to accommodate their large size and inhibit ease of portability and storage of the objects. Thus, there remains a need for an improved support/foot for use on loose sand.
- There is a need for an improved support for an object on soft, granular surfaces. In particular, there is a need for design that reduces the tendency of a the leg to “bore into”, “drill into” or “sink into” the surface and which facilitates supporting the object on top of the soft, granular surface. In some cases the object may be a cart, dolly, trailer, or the like that requires support in addition to its wheels. In other cases the object may be a chair, table, stool, or the like on soft surfaces such as loose sand.
- In accordance with the present invention, a foot is provided which displaces sand radially inwardly and upwardly into a concave cavity, in effect, compressing the sand into the cavity. The concavity of the foot is able to collect sand over which it is placed and compress it under the foot rather than displace it outwardly away from the foot or leg. When the foot is removed from the surface, the sand remains in place as part of the surface, or by the force of gravity falls from the concave cavity back to the surface. The foot or feet of the present invention can be attached to support legs of an object or can be attached to the body of an object to support the object on soft granular surfaces.
- Further understanding of the present invention will be had from the following description and claims taken in conjunction with the accompanying drawings.
-

Domes sand foot 10,sand foot 100,sand foot 200 andsand foot 300 operate in soft sand as follows. Thus, when initially contacting loose sand granules, the concave interior of the dome is empty of sand granules and the sand foot is supported on the sand granules by outwardly facingedge 32. Then, as the sand foot sinks somewhat down into the sand surface, the concavity begins to fill up with sand granules, compressing sand into and against the inner/upper interior surface of the concavity and thereby supporting the sand foot on the sandy surface. A sufficient quantity of sand granules becomes compressed into the concave interior of the dome so that the downward force exerted by dome against the associated sand surface is equally opposed by the sand granules against the dome and its edge. - It will be appreciated by those skilled in the art that the present invention is subject to modification and variation and it is intended that such modifications and variations are considered to be within the broad scope of the invention which is intended to be limited only by the following claims. Such modifications are intended to be included herein so long as they operate in accordance with the principles of this invention.
