   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to utility access structures positioned within asphalt or concrete roads and more specifically it relates to a utility cover system for preventing water leakage into a utility access structure within a road surface and for eliminating the need for expensive adjustment structures. 
   2. Description of the Related Art 
   Utility access structures have been in use for years for various utilizes such as utility valves (e.g. valve covers), sewers (e.g. manholes) and catch basins. The utility access structures typically have a housing structure positioned within the road surface with a cover removably attached thereto. The housing structure and the cover are typically comprised of a hard material such as metal. 
   One of the problems with conventional utility access structures is that they allow surface water to flow into the access structures thereby damaging the components within the access structure. Another problem is that when an asphalt road is resurfaced, an upper portion of the asphalt may be ground off which can cause damage to the access structure. In addition, it is often times required that workers manually remove the asphalt surrounding the access structure which is labor intensive and time consuming. To solve the resurfacing problem, adjustable structures (e.g. adjustment rings, etc.) have been created but they are extremely expensive and noisy for surrounding residents. 
   Examples of patented devices which may be related to the present invention include U.S. Pat. No. 5,536,110 to Tompkins et al.; U.S. Pat. No. 6,196,760 to Sinclair; U.S. Pat. No. 5,723,192 to Jonasz; U.S. Pat. No. 4,368,893 to Gagas; U.S. Pat. No. 5,564,855 to Anderson; U.S. Pat. No. 5,876,533 to House et al.; U.S. Pat. No. 6,179,518 to Suatac; U.S. Pat. No. 4,469,467 to Odill et al.; U.S. Pat. No. 5,299,884 to Westhoff et al.; U.S. Pat. No. 3,858,998 to Larsson et al.; U.S. Pat. No. 4,145,151 to Helms; U.S. Pat. No. 4,540,310 to Ditcher et al.; and U.S. Pat. No. 387,181 to Sinclair. 
   While these devices may be suitable for the particular purpose to which they address, they are not as suitable for preventing water leakage into a utility entrance within a road surface and for eliminating the need for expensive adjustment structures. Conventional utility access structures are prone to water leakage and interfere with road resurfacing. 
   In these respects, the utility cover system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of preventing water leakage into a utility entrance within a road surface and for eliminating the need for expensive adjustment structures. 
   BRIEF SUMMARY OF THE INVENTION

The outer frame  30  may have various shapes such as but not limited to rectangular, circular and the like. The outer frame  30  preferably has an inner segment  34  and an outer segment  36  as shown in  FIGS. 1 and 3  of the drawings. 
   The outer frame  30  is preferably comprised of a resilient and flexible material such as rubber and the like. However, the outer frame  30  may be comprised of a rigid structure. 
   The outer segment  36  preferably is thinner than the inner segment  34  forming a stepped structure as best illustrated in  FIG. 2  of the drawings. The inner segment  34  and the outer segment  36  preferably have a common lower portion as further shown in  FIG. 2  of the drawings. The lower portion of the outer segment  36  is preferably positioned upon the old road surface  14 , wherein the old road surface  14  may have been ground to a lowered level through resurfacing procedures. The lower portion of the outer frame  30  is preferably attached and sealed utilizing an adhesive or other bonding agent. The outer segment  36  of the outer frame  30  is utilized for receiving the new road surface  16  applied over the old road surface  14  as shown in  FIGS. 6 and 7  of the drawings. 
   As shown in  FIG. 2  of the drawings, the inner tapered edge  32  tapers inwardly and upwardly. The inner tapered edge  32  may have an angled structure, curved structure or other shaped structure. The wedge cover  20  is formed to preferably snugly fit within the opening within the outer frame  30 . 
   C. Wedge Cover 
   The wedge cover  20  has an outer tapered edge  24  that corresponds to the inner tapered edge  32  of the outer frame  30  as shown in  FIGS. 1 through 3  of the drawings. The wedge cover  20  may have various shapes such as but not limited to rectangular, circular and the like. However, the wedge cover  20  is preferably formed to a shape and size similar to the opening within the outer frame  30 . 
   The wedge cover  20  is preferably comprised of a resilient and flexible material such as rubber and the like. The flexibility of the wedge cover  20  allows it to be removed from the outer frame  30  by prying with a tool  15  or other device. 
   As shown in  FIG. 2  of the drawings, the outer tapered edge  24  preferably tapers inwardly and upwardly corresponding to the inner tapered edge  32 . The wedge cover  20  is removably positionable within the opening of the outer frame  30  as best shown in  FIGS. 6 and 7  of the drawings. 
   As shown in  FIGS. 1 and 3  of the drawings, the wedge cover  20  has a bottom surface  26  that is positionable over a utility cover  12 . The wedge cover  20  further has an upper surface  22  that is substantially parallel to an upper portion of the outer frame  30  when positioned within the outer frame  30  as shown in  FIGS. 4 through 6  of the drawings. 
   As shown in  FIGS. 1 and 2  of the drawings, the opening and the wedge cover  20  preferably have a similar shape. The wedge cover  20  is preferably positionable in a sealable manner within the opening of the outer frame  30  to prevent water and other debris from entering the utility housing  13  thereby protecting the utility such as a valve  18 . 
   D. Operation 
   In use, the user first positions the outer frame  30  about a utility cover  12  of the utility access structure. The user preferably secures and seals the outer frame  30  to the old road surface  14  surrounding the utility housing  13  of the utility access structure. After the outer frame  30  is fully secured, the user then positions the wedge cover  20  within the opening of the outer frame  30  defined by the inner tapered edge  32  as shown in  FIG. 4  of the drawings. It can be appreciated that the wedge cover  20  may be first positioned adjacent to the utility cover  12  prior to or simultaneously with the application of the outer frame  30 . A layer of new road surface  16  is positioned upon the outer segment  36  and substantially flush with the inner segment  34  as shown in  FIG. 5  of the drawings. If required, the present invention may be stacked to achieve various heights. If an individual desires to access the utility access structure, they simply insert a tool  15  between the wedge cover  20  and the outer frame  30  thereafter prying the wedge cover  20  from the outer frame  30  as shown in  FIG. 7  of the drawings. The individual may then access the utility by removing the utility cover  12  and perform the desired procedures. When finished, the utility cover  12  is returned to the utility housing  13  and the wedge cover  20  is repositioned in a sealed manner within the opening of the outer frame  30 . If the road is to resurfaced in the future, the outer frame  30  and the wedge cover  20  may remain during the grinding of the road surface and may be ground along with the asphalt.
