Concrete pole base cover
A cover for a concrete pole base of a pole assembly includes a cylinder-shaped wall and an upper wall at least partially closing the open upper end of the cylinder-shaped wall. The upper wall has an opening for receiving the post of the pole assembly, which is anchored to the ground by the concrete base. The cylinder-shaped wall has an inner diameter and a height sized to cover and enclose the concrete base. The upper wall has a plurality of nested regions of reduced wall thickness to form score lines to facilitate cutting the cover to increase adjust the height or the diameter of the opening to accommodate different pole assemblies.
The present invention generally relates to a cover for a concrete base, for example, a concrete pole base, and, more particularly, to a cover for a concrete lamp pole base.
It is common practice to mount a pole, such as a lamp pole, on a concrete base, which is embedded or otherwise mounted to the ground. However, over time the appearance of these concrete bases tends to degrade from stains from either rust that accumulates at the pole mounting plate and/or the concrete anchor bolts that mount the pole to the concrete base or from iron deposits from sprinkler water distributed by sprinkler systems. In an effort to hide these unsightly stains, some concrete bases are painted. However, once painted, the bases have to be maintained and repainted periodically to maintain their aesthetic appearance.
Consequently, there is a need for a method or device that can conceal concrete bases to hide these stains or other markings which may appear on the bases, such as graffiti, but without requiring any significant maintenance.
SUMMARY OF THE INVENTIONAccordingly, the present invention provides a cover for a concrete pole base that may be mounted on the base after the base is installed in the ground. The cover is made from a material that is not subject to rusting and, preferably, also not subject to staining or that can at least be washed to remove any dirt or debris that may adhere to the outer surface of the cover to maintain the overall aesthetic appearance of the pole and base.
In one form of the invention, a cover for a concrete pole base includes a cylinder-shaped wall, with an open upper end and an open lower end, and an upper wall that at least partially closes the open upper end of the cylinder-shaped wall. The upper wall includes an opening for receiving the post. The cylinder-shaped wall has an inner diameter and a height sized to cover and enclose the concrete base. The upper wall also includes a plurality of concentric regions of reduced wall thickness to form score lines to facilitate cutting the cover to increase the diameter of the opening to accommodate different pole sizes.
In one aspect, the opening in the upper wall is a round or a square opening. In another aspect, the regions of reduced wall thickness are formed by grooves or recesses. In yet another aspect, the upper wall is flat.
According to other aspects, the cylinder-shaped wall comprises a round cylinder-shaped wall or a multi-sided cylinder-shaped wall. Further, the cylinder-shaped wall may have a plurality of vertically spaced regions of reduced wall thickness to form score lines to facilitate cutting the cover to decrease the height of the cylinder-shaped wall to accommodate different base heights.
In a further aspect, the cylinder-shaped wall and the upper wall comprise plastic wall.
An additional feature that may be provided includes an outwardly extending flange, which is provided at the open lower end of the cylinder-shaped wall. The flange projects outwardly from said cylinder-shaped wall to form a perimeter flange or skirt around the cylinder-shaped wall. For example, the skirt may discourage the growth of grass around the outer perimeter of the cylinder-shaped wall. The flange may include an upwardly extending lip, which extends into the open lower end of the cylinder-shaped wall between the concrete base and the cylinder-shaped wall to thereby anchor the flange about the concrete base with the cylinder-shaped wall.
In yet a further aspect, the cylinder-shaped wall may be formed from two half-cylinder-shaped walls, which interlock together to form the cylinder-shaped wall. For example, each of the half-cylinder-shaped walls includes a vertical edge, with each of the vertical edges including at least one connector for interlocking the half-cylinder-shaped walls together. In addition, each of said vertical edges may include a lip that overlaps with a corresponding lip on the vertical edge of the other half-cylinder-shaped wall.
In another form of the invention, a pole assembly and concrete pole base cover includes a post and a concrete base, with the post being anchored to the concrete base by a plurality of concrete anchors bolts. The concrete base has a cylinder-shaped concrete body with a top surface spaced above the ground when installed, a lower end for anchoring in the ground, and an intermediate portion extending above the ground from the lower end. The concrete anchor bolts anchor the post to the base at the top surface of the base. The cover includes a cylinder-shaped wall with an open lower end and an open upper end, which is sized to fit over the anchors bolts and the concrete base and to extend over the top surface and cover the intermediate portion of the cylinder-shaped concrete body wherein the cylinder-shaped wall extends to the ground. The cover also includes an upper wall at least partially closing the open upper end of the cylinder-shaped wall. The upper wall includes an opening for receiving the post. The cylinder-shaped wall has an inner diameter and a height sized to cover and enclose the anchor bolts and the intermediate portion of cylinder-shaped concrete body.
In one aspect, either the upper wall or the cylinder-shaped wall has a plurality of regions of reduced wall thickness to form score lines to facilitate cutting the cover. For example, the upper wall may have score lines to facilitate cutting the cover to increase the size of the opening to accommodate different post sizes.
In another aspect, the pole and pole cover may also include an outwardly extending flange similar to the flange described above.
According to another aspect, the cylinder-shaped wall is formed from two half-cylinder-shaped walls that interlock together to form said cylinder-shaped wall.
In yet another form of the invention, a concrete pole base cover includes a cylinder-shaped wall, with an open upper end and an open lower end, and an upper wall that at least partially closes the open upper end of the cylinder-shaped wall. The upper wall includes an opening for receiving the post of a pole assembly. The cylinder-shaped wall has an inner diameter and a height sized to cover and enclose the concrete base that anchors the post to the ground. In addition, a skirt is provided that extends around the cylinder-shaped wall. For example, the skirt may discourage the growth of grass around the outer perimeter of the cylinder-shaped wall.
In one aspect, the skirt includes an outwardly extending flange with an upwardly extending lip, which extends into the open lower end of the cylinder-shaped wall between the concrete base and the cylinder-shaped wall to thereby anchor the skirt about the concrete base with the cylinder-shaped wall.
In yet a further aspect, the cylinder-shaped wall may be formed from two half-cylinder-shaped walls, which interlock together to form the cylinder-shaped wall. Similarly, the skirt may be formed from two skirt halves.
Accordingly, the present invention provides a cover for a concrete pole base, such as a concrete light pole base, that will protect the base from damage or corrosion due to sprinkler water, flying debris from lawn mowers, and will also cover defects or stains in the base.
These and other objects, advantages, purposes, and features of the invention will become more apparent from the study of the following description taken in conjunction with the drawings.
Referring to
In the illustrated embodiment, cover 10 includes a split housing construction with first and second cover halves 12 and 14, each having a substantially identical construction so that they may be molded or formed from the same mold. When mounted about pole assembly P and base B, cover 10 preferably covers the full length of the exposed portion of base B, which is typically cast in place and partially embedded in the ground G, so that cover 10 extends to or just above or just below the surface of the ground G. The post of the pole assembly P is typically welded to base plate M, which in turn is anchored to base B by concrete anchor bolts A. However, it should be understood that the post may be mounted to base B using other mounting devices.
The cover halves 12 and 14 are interconnected together by a plurality of connectors that are either formed or provided on or about the cover halves. In the illustrated embodiment, cover halves 12, 14 include projecting structures, such as tabs 24, and receiving structures, such as receptacles 26, that are formed at the edges 16, 18, 20, 22 of their respective cover halves. For example, edges 16 and 20 may be molded with projecting tabs 24, while edges 18 and 22 may be molded with receptacles 26. Alternately, as shown, each edge may be molded with tabs and receptacles in an alternating pattern so that when oriented about the base the tabs on one of the cover halves will extend into and engage the receptacles on the other cover half.

It should be understood that the configuration and arrangement of the various connectors that may be used to join the cover halves vary considerably. For example, the cover halves may have pin/socket connectors that provide, for example, a snap fit connector. In addition, the cover halves may be hinged at one set of edges, for example by a living hinge, with their other edges provided with connectors, such as described above. Alternately, the cover halves may be secured together by one or more straps that extend around the cover halves. It should be understood that the connectors provided and described herein are not exhaustive and are exemplary only.
As best seen in
Referring to
In the illustrated embodiment, cover 10 includes a cylinder-shaped wall 44, which is formed from the semi or half-cylinder-shaped walls 44a and 44b of cover halves 12 and 14. The lower open end 46 of cylinder-shaped wall 44 is sized to extend around the full circumference of the concrete base B and, further, may be optionally sized to provide a close fit with concrete base B or to provide a gap, for example, to facilitate the installation of a skirt described more fully below. Upper open end of cylinder-shaped wall 44 is closed by upper wall 40, which includes opening 42 to receive post P. In the illustrated embodiment, upper wall 40 includes a central wall portion 48, which is generally horizontal or orthogonal to cylinder-shaped wall 44, and an annular or perimeter wall portion 50 that extends around central wall portion 48 and which connects cylinder-shaped wall 44 to central wall portion 48. Annular wall portion 50 is optionally inclined, for example, at an angle to discourage items, such as customer's cans or bottles, from being deposited on the top of the cover. For example, a suitable inclination may be in a range of 10° to 30°, optionally in a range of 15° to 20° and, more preferably, about 17°. Further, as noted above, upper wall 40 may include a plurality of regions of reduced wall thickness to form score lines, which may be formed in the inner surface of wall 40 or may be formed on the upper surface of wall 40. Further, these score lines are preferably located in central wall portion 48, though they may extend into the angled annular wall portion 50. Although illustrated in reference to a round or circular cover, it should be understood that the shape of the wall may assume other cylinder shapes including multi-sided cylinder shapes, such as a square, hexagon, octagon-shaped, or the like. Further, although described in reference to identical cover halves, it should be appreciated that the cover may be formed from non-identical or non-symmetrical or non-mirror image cover halves, though it would be understood that with such a modification, the cost to form the respective cover would increase.

Covers 10, 110 may be formed from a moldable material, such as a polymer, including polyurethane, plastic, fiberglass, or a wood composite material, or may be formed from wood or a composite material. Alternately, covers 10, 110 may be formed from a non-rusting metal, such as aluminum or stainless steel. In preferred form, covers 10 and 110 are formed from a moldable material, such as a polymer, so that various designs, wording, trademarks, or textures or colors the like may be incorporated into the cover. For example, referring to
While described as having a split construction, the covers of the present invention may be formed from a single member. For example, the cover may form the mold or form for the concrete base. In this application, the cover would more closely resemble cover 110 with the upper wall having a plurality of anchor bolt holes or openings, but with each opening optionally having associate therewith a collar that is threaded or otherwise configured to hold the anchor bolts while concrete is being poured into the cover, for example through the post opening in the upper wall.
As would be understood, the covers of the present invention protect the concrete base B from the elements and, further, cover any stains or any imperfections in the concrete base itself. The covers can also hide surface imperfections in the concrete base, such as the honeycomb effect that is created during the concrete molding process due to impressions left from the forms or holes caused by air bubbles in the concrete, both of which produce unsightly surface defects. These defects are typically removed or reduced by sanding or otherwise finishing the outer surface of the concrete base. Therefore, the covers of the present invention can eliminate the need for the finishing step when forming the base, which can save significant installation costs.
Referring again to
Additionally, when formed from a polymer or wood, covers 10 and 110 may incorporate a protective ring, such as a metal ring, including an aluminum or stainless steel ring, that protects the lower portion, such as the lower 3″ of the cover, from damage. For example, damage can occur from a weed-whacker where the skirt is not utilized or from rocks or debris that may be kicked up from a lawn mower. The ring may have a channel-shaped lower portion that receives the lower open end of the cover to thereby secure the ring in place.
Accordingly, the present invention provides a cover that protects a concrete base of a pole assembly from degradation due to impingement from water spray or salt that may be dispersed by sprinkler systems or a salt truck. Further, the cover may provide an aesthetic appearance to base B while covering the base's imperfections due to stains that often occur with concrete bases or due to the base forming process. In addition, the cover eliminates the need for the final finishing step of the base after the base has been poured and the form of the base has been removed. Further, the cover is adapted to be sized on site to accommodate different pole shapes and sizes and also may be adapted on site to suit different base heights.
While several forms of the invention have been shown and described, other forms will now be apparent to those skilled in the art. Therefore, it will be understood that the embodiments shown in the drawings and described above are merely for illustrative purposes, and are not intended to limit the scope of the invention which is defined by the claims which follow as interpreted under the principles of patent law including the doctrine of equivalents.
