The technology described and claimed herein relates to the general field of portable support apparatus, and has certain specific application to portable support apparatus for use where a penetrable ground surface exists, such as where dirt, turf, or mud exists, whether outdoors or indoors.
Known portable support apparatus include the tables described in U.S. Pat. Nos. 6,705,240 and 8,573,138. A common feature among such tables is the use of just one or two connected ground-penetrating spikes that are simply an extension of a vertical table leg. Similarly, known temporary portable apparatus include real estate yard signs that are simple rectangular frames having opposed parallel top and bottom horizontal members that are connected by two opposed vertical side members, with the two side members each including a pointed leg portion that extends below the bottom horizontal frame member to provide for penetrating ground contact. When the pointed leg portions are each pressed into a ground surface, the legs support the sign in a vertical position. However, in each of these prior art examples, due to the minimal penetrating ground contact points provided, such signs and tables are easily toppled or leaned by wind, impacts, softening of ground by rain, and other forces. Such tables and signs are also unsuitable for installing on sloped ground surfaces.
For all these reasons, there remains an unmet need for a support apparatus that can be easily installed and removed in a wide variety of sloped ground surfaces, and that remains in stable contact with a flat or sloped ground surface and in a desired substantially vertical position despite the application of external forces such as wind, gravity, contact with moving items, and by the weight of umbrellas, signage, or other items supported by the portable support structure.
The instant inventions relate to the general field of portable structures, and have certain specific application to portable supportive stands that can be repeatedly and removably engaged by a user into a land surface such as turf, topsoil, or other similar surfaces.
In an embodiment, a support apparatus comprises a base portion configured and disposed for securely and removably engaging a ground surface, and a support portion comprising a first end adjacently connected to the base portion and an opposite second end adjacently connected to a top portion, the top portion comprising handle means. Preferably, the base portion comprises a bridge and at least two anchors, the anchors projecting downward away from the bridge, and the bridge is configured and disposed to receive and transmit a user force to the anchors sufficient to drive the anchors into a ground surface. Most preferably, the base portion further comprises at least one blade, the blade disposed below the bridge and configured for penetrating and engaging a ground surface to add stability to the apparatus when installed on the ground surface.
In another embodiment, a support apparatus comprises a base portion configured and disposed for securely and removably engaging a ground surface, a support portion comprising a first end adjacently connected to the base portion and an opposite second end adjacently connected to a top portion, the top portion comprising handle means, wherein the base portion comprises at least two anchors, and a bridge, the bridge configured and disposed to receive and transmit a user force to the anchors sufficient to drive the anchors into a ground surface, and wherein the handle means and the blade are configured and disposed in a coplanar orientation. Optionally, the base portion further comprises a blade portion, the blade portion disposed below the bridge and configured for engaging and penetrating a ground surface.
Further provided are methods of installing the support apparatus, comprising the steps of contacting the anchors to a ground surface, followed by application of downward force onto a handle and a onto a bridge of the apparatus, such force applied simultaneously with a rocking of the apparatus within the plane of the handles and bridge so as to cause the anchors and a blade of the apparatus to penetrate the ground surface to a desired depth.
Accordingly, an object of this invention is to provide for a novel multi-purpose support apparatus for use on any penetrable ground surface. Another object is to provide a multi-purpose support apparatus suitable for anchoring attachments such as tables, umbrellas, pets, and other accessories regardless of the slope of the ground surface.
Other objects will become apparent upon a reading of the following description.
The following is a detailed description of exemplary embodiments to illustrate the principles of the invention. The embodiments are provided to illustrate aspects of the invention, but the invention is not limited to any embodiment. The scope of the invention encompasses numerous alternatives, modifications and equivalent; it is limited only by the claims. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. However, the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.
The apparatus of the present invention is comprised of a supporting framework that can be easily and removably mounted into a variety of penetrable ground surfaces. Installation is made simpler than any prior art device by the inclusion of a handle portion and a force-receiving bridge portion, as further described and shown herein.
Referring now to the drawings,
As shown, the base portion 30 comprises at least two anchors 32 that are configured and disposed for penetrating the ground surface 200. As shown in
In each embodiment, a ground contact blade 50 is provided. The function of the blade 50 is to penetrate the ground surface 200 and thereby provide stabilizing support to the support apparatus 100. The blade 50 provides additional contact area between the base portion 30 and the ground surface 200. For example, upon insertion of the anchors 32 into a ground surface 200, the blade 50 also penetrates and contacts the ground surface 200. In this manner, the blade 50 provides stability against leaning, tipping, and also against rotation of the apparatus 200 around a center vertical axis A-A of the apparatus 100. As further shown in
Returning to the figures, as shown in the embodiment of
In experiments, the inventor has found that the height of the blade 50 extending from its bottom edge 52 upward towards the middle portion 20, and the depth to which the bottom edge 52 is plunged into a ground surface 200, significantly affect the stability of the apparatus 100 when placed in sloped ground surfaces 200, and also when subjected to external forces after installation into a ground surface 200. Moreover, the blade 50 provides a unique advantage in installing the apparatus 100 into a ground surface 200, and it surprisingly pushes rocks and other obstacles beneath the ground surface 200 aside easily, especially when using the installation methods herein.
For example, as shown in
Removal of the apparatus 100 from the ground surface 200 is surprisingly simple and easy due to the handles 12. Preferred removal methods utilize the coplanar rocking motion previously described and shown in
As shown in
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made, and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
