The present invention relates to a metal or plastic device that goes beyond prior art and products currently available in the marketplace with a novel design that provides enhanced protection from moisture induced damage such as tot in wood posts, deformation in plastic and wood posts, and oxidation in metallic and plastic posts. This Invention also goes far beyond the prior art and currently available products in the marketplace by greatly enhancing the ease, efficiency, and outcome of post Installation and replacement. The prior art mentioned below is related to post fixtures and sleeves above and below ground. This Invention was originally derived absent knowledge of the prior art listed below and is unique and novel as compared with it. The only commonality with the prior art listed below is that the inventions deal with posts and/or the device attaches in some manner to the post.
The use of support devices and protective sleeves for ground anchors is known in the prior art. By way of example, U.S. Pat. No. 5,203,317 to Klumpjan discloses a fence post bracket capable of holding the post above ground level to provide drainage and reduces deterioration. U.S. Pat. No. 5,720,134 to Kurtz discloses a support post utilizing a plastic base to prevent wood rot from moisture, U.S. Pat. No. 5,733,613 to Baecker discloses an invention utilizing a plastic sleeve to cover a wood pole to prevent deterioration. U.S. Pat. No. 6,386,296 to John and John discloses an invention that provides a plastic collar dimensioned for receiving this lower end of the wooden post that makes the claims of aiding in the protection of the lower end of a wooden post from rotting within a hole in the ground while making insertion and removal from the hole easier.
While these inventions fulfill their respective intentions and general objectives, the majority of the aforementioned patents do not describe an in-ground device that protects the post in the same technical manner as presented in this invention. U.S. Pat. No. 6,886,296 does make the claim of protecting the post with a plastic sleeve. Moisture damages posts of most materials placed in the ground. Moisture will cause some damage to posts to occur below ground level in dirt, rock, or cement. The greatest damage to posts from moisture is usually right at the interface of the post to ground or the in-ground fixture. U.S. Pat. No. 6,886,296 utilizes a plastic device that is according to the invention dimensioned for receiving the lower end of a wooden post or similar in dimension to the post. The snug fit, as opposed to an open fit, of the sleeve in U.S. Pat. No. 6,886,296 described, can result in moisture being held at the interface of the post and the ground and/or the post and the sleeve. Also, it can result in moisture escaping more slowly from the pert of the post below the ground. The invention described in the matter of this current application enables air flow around the entire post inside the device including in the ground and at the ground and device level. This greatly enhances the protection of the post helping the whole post perform similarly from a damage point of view to the part of the post that sticks out of the ground (e.g. the post performs similarly to a post that is completely above ground).
U.S. Pat. No. 6,886,296 to John and John also claims improved the insertion and removal. However, it does not address the challenges of post placement relative to the structures (for example: fences, decks, light posts and other) the posts are integral with for new and replacement applications as this invention does. This invention, the subject of this application, allows for the placement and preparation (digging, device ready, and cement, dirt, rock, etc., backfill) of all of the holes absent the post and the structure. The advantage is similar to a custom Job shop factory (prior art) versus an assembly line (new invention), as the holes can be fully prepared absent the posts and any other part of the structure. Also, this invention allows for very easy replacement due to the margins discussed as part of the device design. Structures settle, shift, warp, and otherwise change over time preventing a perfect fit to original layout and specifications. This invention, via the margin in the device, allows a post to be replaced without significant difficulty or changes/modifications (for example: jacking up as structure, trimming or otherwise modifying it, etc.) and to result in a replaced post with the strength and rigidity of a brand new installation. The prior art, again, is similar to custom work with it costs, time, effort, and variation of result vs. an efficient and predictable assembly line like setup. Furthermore, the new invention, as opposed to the prior art, always produces a superior, sturdy, repeatable fixation of the post to the ground.
