The present invention relates generally to post covers, bollards, and the like, and more particularly, to a protective cover for a stanchion or post that includes an upper vessel for a plant or other application.
Stanchions or posts are commonly found in industrial and commercial settings to protect a building structure or fixed equipment from vehicular traffic. Guard posts or protective stanchions are commonly found in public parking lots and the like to protect drive-up windows and equipment, telephone booths, store entrances, and so forth.
Existing guard posts and protective stanchions often comprise a steel post set in the ground or pavement with a portion of the post projecting a desired amount above the pavement surface, commonly on the order of about four feet or so. To enhance the durability of such a steel pipe stanchion, one may fill the steel pipe with concrete. This both closes the interior of the pipe to environmental deterioration and enhances the structural integrity and impact absorbing qualities of the stanchion.
Further, existing stanchions are typically painted to preserve the exterior of the stanchion and resist deterioration by rusting or the like. Protective stanchions are also painted to provide a high visibility color.
However, steps to enhance the durability of a protective stanchion such as painting are typically labor-intensive and require repetitive maintenance to repair chipped paint, worn surfaces, or discoloration over time.
To address this maintenance problem, U.S. Pat. No. 5,323,583 provides a protective sleeve for upright posts and stanchions. The sleeve comprises an elongated body extending between two opposing ends and an interior cavity extending along the sleeve and through at least one of the two opposing ends. Further, the interior cavity has a cross-sectional shape adapted for slip fit engagement with the post. The post is inserted into the interior cavity and the sleeve force fit over the post. According to a preferred embodiment, the sleeve includes a decorative feature in the form of a smooth hemispherical top on the closed opposing end, as shown and claimed in U.S. Pat. No. D464,585. A textured version is shown and claimed in U.S. Pat. No. 426,898.
Post sleeves have also been combined with other features. For example, U.S. Pat. No. D374,941 is directed to an ornamental design for a combined stanchion with sleeve and signage. In terms of installation, U.S. Pat. No. 6,209,276 describes the way in which trapped air is used to hold a sleeve onto an elongated member such as a vertical post or pillar. At least one spacer is provided circumferentially around the member, which is positioned proximate to the end over which the open end of the sleeve is placed for installation purposes. As the sleeve is subsequently urged over the member, air trapped between the end of the member including the spacer and the closed end of the sleeve is expelled past the spacer and out the open end of the sleeve between the outside wall of the member. With such a configuration, if one then attempts to pull the sleeve off the member, air movement past the spacer in the opposite direction is again very slow, preventing the sleeve from being pulled off the member without a substantial effort.
This invention resides in post covers, bollards, and the like, and in particular, provides a protective cover for a stanchion or post that includes an upper vessel for a plant or other application. For example, sleeves according to this invention include upper vessels that may be used as planters, ashtray, or other purposes, thereby enhancing their utility and/or decorative affect.
This invention relates to sleeves used to cover posts, stanchions, and the like. These are often found out-of-doors, to protect vehicles, and to provide other applications, features of this type often being referred to as “bollards.” In distinction with previous designs, the sleeves according to this invention include upper vessels that may be used as planters, ashtray, or other purposes, thereby enhancing their utility and/or decorative affect.
The diameter D may any appropriate size, such as from the range of 3 inches to 10 inches, or greater, depending upon the application and the type of post being covered. Height is also flexible, and may range from 3 feet or less for an ashtray or low-to-the-ground planter purposes, to 6 feet or more. Although the sleeve portion shown below the upper vessel is cylindrical in the preferred embodiments, this is not necessary to the invention, as square, polygonal (3-, 5-, 6- 7-, 8-sided, and so forth), oval and other cross-sectional shapes may be used.
In terms of materials, the sleeves according to this invention may be made of any plastic or polymeric material, and may be molded in any way, such as rotational molding, blow molding, and so forth. The devices may be colored in any fashion, as appropriate, including multicolors from the same mold. In-mold decals and other features may also be incorporated into the design.
This application claims priority from U.S. Provisional Patent Application Ser. No. 60/495,933, filed Aug. 18, 2003, the entire content of which is incorporated herein by reference.
