Problems solved by technology

While the manhole and its opening are initially almost unnoticeable, the changing surfaces and environment usually reveal the manholes and other gratings after some time.
When this occurs, traveling over the manhole cover can become very uncomfortable and potentially unsafe because it can damage vehicles or cause drivers to try to avoid them.
There have been attempts in the past to address this issue but they have proven time consuming and expensive.
For example, one solution is to extend the collars 104 in some manner such as with supplementary collars or extension rings to raise the height of the manhole cover; but this is labor and time intensive as well as expensive.

Embodiment Construction

[0022]The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the invention.

[0023]As used herein, the phrase manhole cover is meant to encompass a wide variety of covers that are used to cover subterranean openings. These include manholes to access sewers or other utilities occurring in any location. Such openings can particularly occur on a sidewalk or on a roadway where there is vehicle or pedestrian traffic. Additionally...

Abstract

Embodiments of the present invention relate to a cover for a manhole or similar structure that encapsulates a traditional cover so as to extend the height of the cover. Generally, a conventional manhole cover is partially or entirely encapsulated in polyurethane to change its outside dimensions to match the environment of an intended location.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a manhole cover and, more particularly to an encapsulated manhole cover.[0003]2. Description of Related Art[0004]In many urban areas the benefits of underground utilities require numerous manholes and other openings to be provided on the streets and sidewalks. While the manhole and its opening are initially almost unnoticeable, the changing surfaces and environment usually reveal the manholes and other gratings after some time.[0005]For example, FIG. 1 illustrates a conventional manhole cover arrangement. An opening 100 is protected by a manhole cover 102 that sits on a circular collar 104 that is generally the same height as a road 106 or other above-ground surface. The design of the collar 104 and cover 102 ensures that the entire arrangement is generally smooth. For example, in the roadway environment, the intention is for a vehicle to be able to pass over the cover 102 with...
