FIELD OF THE INVENTION

The present invention relates to protective covers for bases of utility poles such as street light poles, in particular covers for raised concrete bases for light poles.

BACKGROUND INFORMATION

Utility poles such as light poles located in parking lots and along roadways are often mounted on concrete bases. These bases typically extend well above grade level to protect the pole from damage by vehicles. This is an effective design for securely holding the pole and also protecting it from damage. However, the concrete base itself often becomes worn or damaged due to weathering and vehicle impacts and may need replaced or repaired. The poles are usually bolted onto anchors extending from the pole base. Such bolts and anchors tend to rust and deteriorate due to exposure to the elements. Aside from being unsightly, the rusted hardware and weathered or damaged pole bases may become structurally unsound.

The present invention has been developed in light of the foregoing.

DETAILED DESCRIPTION

As shown in FIGS. 1 and 2, a protective utility pole base cover 1 surrounds a pole base 2. The protective utility pole base cover 1 includes a cover wall 4 surrounding the pole base 2, a cover top 5 on top of the cover wall and a cover boot 6 on top of the cover top 5 and surrounding a utility pole 3. The utility pole 3 may be a light pole, or any other structure mounted on top of a pole base. The pole base 2 may be a concrete structure embedded in the ground for supporting the utility pole. The protective utility pole base cover 1 has an outer diameter, shown as D in FIG. 1. The outer diameter D is for example, between 1 and 3 feet. The protective utility pole base cover 1 also has an overall height, shown as H_T in FIG. 1. The height H_T is for example, between 1 and 4 feet. The cover wall 4 has a wall height, shown as H_w in FIG. 1. The height H_w is for example, between 1 foot and 3 feet. The cover top 5 and the cover boot 6 have a combined height, shown as H_c in FIG. 1. The height H_c is for example, between 3 and 24 inches.

In the embodiment shown in FIG. 2, the cover wall 4 is made up of slats 8. The individual slats 8 may have a raised reinforcement portion 12 to provide rigidity for the slat 8 and provide protection for the pole base 2. Reinforcement portions 10 may be vertical or of other orientation. The slats 8 connect together by way of interlocking portions 10. The interlocking portions 10 may have a slide or slip lock with interlocking shapes that hold the sections together.

Different embodiments of the present invention may have varying numbers of wall sections, for example, one embodiment may have two interlocking or otherwise fastened semi-circular sections. Another embodiment may have a one-piece cover wall 4. The cover wall may have one or more cover wall sections which are secured with mechanical fasteners or adhesive. The one or more cover wall sections may also have reinforcement portions 10.

FIG. 3 shows an example of a slip lock joint according to one embodiment of the present invention. Each slat 8 may have a reinforcement portion 12 and two interlocking portions 10. The interlocking portions 10 of each slat 8 are congruently shaped to fit the reinforcement portions 10 of other slats 8. Slats 8 may be substantially flat so that each interlocking portion rotates to conform to the pole base 2, or the slats 8 may be formed to have a radius matched to the radius of the pole base 2. The slats may also be flexible enough to conform to the pole base 2 without pre-formed bends.

In one embodiment, the height of the protective utility pole base cover 1 is adjustable by cutting the cover wall to conform with the height of the pole base 2 and/or to conform to the terrain surrounding the pole base 2. The top and bottom of the cover wall 4 may be trimmed to conform to the top of the pole base 2 or bottom where the sections touch the ground.

The cover top 5 is mounted on the cover wall 4 and covers the utility pole base 2, with an opening that surrounds the utility pole 3. The cover top 5 may optionally be mechanically secured or friction fit to the cover wall 4, however this is not required. The cover top 5 may be made up of two semi-circular sections joined together to make one cover top 5 that encircles the pole 3. Each cover top section 7 has a sidewall 14 and a top surface 15. The cover top sections 7 may be held together by cover top locking tabs 22. Each of the cover top locking tabs 22 is overlapped by the opposite cover top section 7. Overlapping the cover top locking tabs 22 with the opposite cover top section enable the sections to be fastened together. In one embodiment, mechanical fasteners running through the cover top locking holes 24 and into the cover top locking tab 22 of the opposite cover top section 7 hold the cover top sections 7 together. The mechanical fasteners may be, for example, plastic or metal pins or plastic or metal screws. Each cover top section 7 may also have a sidewall 14 protruding axially along the pole base 2. The sidewall 14 assists in securing the slats 8 to the pole base 2 and fills any gaps between the slats 8 and cover top 5. Other embodiments of the present invention may include a one-piece cover top 5 or a plurality of cover top sections 7.

The cover boot 6 sits on top of the cover top 5. The cover boot 6 is also made of two cover boot sections 9 which are shown in greater detail in FIG. 4. The cover boot sections 9 shown in the embodiment depicted in FIGS. 2 and 4 are each equal halves of a hemisphere. Each cover boot section 9 has a pole opening 16 which substantially conforms to a cross-section of the pole 3. This cross-section may be for example, rectangular, square or circular. The pole opening 9 may be equipped with a gasket to seal tightly to the pole 3 to keep water from entering the protective utility pole base cover 1. The gasket may be a rubber portion fitted between the cover boot 6 and the pole 3 or may be caulking, for example silicon, between the cover boot 6 and the pole 3. The gasket prevents water from getting inside protective utility pole base cover 1. Each cover boot section 6 also has a boot locking tab 18 that is overlapped by the opposite cover boot section 9. In one embodiment, the bolt locking tab 18 interlocks with the opposite cover boot section 9 through the use of mechanical fasteners, such as plastic pins through bolt locking holes 20. Other embodiments of the present invention may include a one-piece cover boot 6 or a plurality of cover boot sections 9.

A beneficial feature of the cover boot 6 that it is not attached to the cover top 5. This allows the cover boot to float or have radial flexibility in relation to a central longitudinal axis of the pole base 2. The flexibility allows the cover boot 6 to fit tightly against the pole and still cover the pole base 2 while resting on an appropriately sized cover wall 4. Radial flexibility is beneficial because the poles 3 are often not concentric with or center on the pole bases 2. This could require that an oversized cover wall 4 be used or that a custom made cover be made if the cover boot 6 where radially fixed. The radial movement of the cover boot 6 in relation to the cover top 5 and cover wall 4 remedies this problem as it relates to providing a cover for the pole.

In another embodiment of the present invention shown in FIG. 5, a one-piece cover wall 34 surrounds a pole base 32. The one-piece cover wall 34 is either hinged or flexible enough to be installed around pole base 32. A cover top 35 is mounted on and secured to the one-piece cover wall 34 as described above. The cover top is a two piece design having a sidewall protruding axially along the pole base as described above. The cover top 35 may have an upwardly and inwardly projecting top surface which provides a transition from the one-piece cover wall 34 to a cover boot 36 which sits atop the cover top 55. The cover boot 35 wraps around the pole 33 a seals against water. A skirt 37 may be placed around the bottom of the protective utility pole base cover 1. The skirt 37 may be a one or two-piece ring that fits over the one-piece cover wall 34 and covers any gap between the cover wall 4 and the ground. The skirt and sidewall of the top cover may provide the means for holding the one-piece cover wall 34 in place around the periphery of the pole base 32. Alternatively, mechanical fasteners or adhesive may also be used to hold opposite circumferential ends of the one-piece cover wall 34 together.

The protective utility pole base cover 1 may be constructed of a material suitable for exposure to an outside environment. Non-metallic materials, such as plastics may be used for this application due to their resistance to deterioration. Many plastics, such as polyethylene, also demonstrate excellent strength and resiliency, which make them suitable for protecting a pole base 2. Other materials, including metallic materials, may be used in fabrication of all or part of the pole base cover without departing form the invention. However, plastics are often the preferred material for this application.

The pole base cover may include additional aesthetic features dependent on the setting to provide a more appealing appearance. Aesthetic features may include additional molding incorporated in as separate elements of the pole base cover. Color selection may also be varied according to the setting.

Whereas particular embodiments of this invention have been described above for purposes of illustration, it will be evident to those skilled in the art that numerous variations of the details of the present invention may be made without departing from the invention as defined in the appended claims.
