A curb box cover assembly includes a covering member having a plurality of first openings for the passage of street water. Also, second opening(s) are provided on the covering member which cooperate with a clamping device to secure the covering member to the catch basin. The clamping device includes one clamp member which includes a first and second contact member connected by a transition member of prescribed thickness. The clamp member rotationally mounts on a pivot member. The pivot member includes a threaded opening to receive a bolt member which is advanced into the threaded opening by an operator's action. The pivot member rotates in response to the operator's action so that the clamp member rotates from a first position to a second position at which the clamp member secures the covering member to the catch basin opening. The contact members can rotate independently of each other to accommodate irregularities in the interior surface of the catch basin.

What is claimed is: 1. A cover assembly for a catch basin opening comprising: (a) a covering member including at least one first opening for the passage of water therethrough, and at least one second opening said at least one second opening positioned on said covering member at a predetermined location; the catch basin opening having a prescribed contour, said predetermined location in close proximity to the contour when said covering member is positioned in its intended place in front of the catch basin opening; and (b) means for clamping the covering member to a portion of the catch basin, said means for clamping cooperatively engaging a respective one of said at least one second opening whereby the covering member covers the catch basin opening, said means for clamping including; (i) at least one clamp member, said at least one clamp member characterized as including at least a first contact member, said at least said first contact member having a respective catch basin contact surface for contacting a respective portion of an interior surface of the catch basin, said at least said first contact member further characterized as including at least a first covering member contact surface position and a second covering member contact surface position; (ii) a rotating member, said at least one clamp member cooperatively engaging said rotating member; and, (iii) means for rotating said rotating member engaged by said clamp member, said rotating member adapted to rotate in response to an operator's action in a manner whereby said at least said first contact member proceeds from said first covering member contact surface position to said second covering member contact surface position; where, at said second covering member contact surface position, said at least said first catch basin contact surface contacts said respective portion of the interior surface of the catch basin, such that said covering member is secured in place over the catch basin opening. 2. The cover assembly claimed in claim 1 wherein said at least one clamp member includes at least a second contact member, said at least said second contact member having a respective catch basin contact surface for contacting a respective portion of the interior of the catch basin, said at least said second contact member further characterized as including a respective first covering member contact surface position and a respective second covering member contact position; where, at its said respective second covering member contact surface position, said at least said second catch basin contact surface of said second contact member contacts its said respective portion of the interior surface of the catch basin. 3. The cover assembly claimed in claim 2 wherein said cover assembly is further adapted so that said at least said first and second contact members can rotate independently of each other such that when the first of said at least said first and second contact members contacts its respective portion of the interior surface of the catch basin, the second of said at least said first and second contact members continues to rotate in response to the operator's action until said second contact member contacts its respective portion of the interior surface of the catch basin. 4. The cover assembly claimed in claim 2 wherein the clamp member includes a transition member, said transition member connected between said at least said first and second contact members. 5. The cover assembly claimed in claim 4, wherein said at least said first and second contact members can rotate independently of each other after the first of said at least said first and second contact members contacts its respective portion of the interior surface of the catch basin, due, at least in part, to the thickness of said transition member. 6. A cover assembly for a catch basin opening comprising: (a) a covering member including at least one first opening for the passage of water therethrough and at least one second opening, said at least one second opening positioned on said covering member at a predetermined location, the catch basin opening having a prescribed contour, said predetermined location in close proximity to the contour when said covering member is positioned in its intended place in front of the catch basin opening; and (b) means for clamping the covering member to a portion of the catch basin whereby the covering member covers the catch basin opening, said means for clamping including; (i) at least one clamp member, said at least one clamp member characterized as including at least a first and second contact member, each said contact member having a respective contact surface for contacting a respective portion of an interior surface of the catch basin, each said contact member further characterized as including at least a first covering member contact surface portion and a second covering member contact surface portion; (ii) a pivot member; and, (iii) a bolt member; said clamp member rotationally mounted on said pivot member about a first axis, said pivot member including a threaded opening having a second axis perpendicular to the first axis, said bolt member positioned through said at least one second opening and advancing along said second axis when threaded into said threaded opening by an operator's action, said pivot member adapted to rotate in response to the operator's action; such that said clamp member is adapted to rotate about said pivot member from a first position to a second position as said bolt member is advanced along said second axis, such that at said second position, said at least one of the contact member's respective contact surfaces contacts its respective portion of the interior surface of the catch basin. 7. The cover claimed in claim 6 wherein said clamp member is adapted such that said at least said first and second contact members can rotate independently of each other such that when the first of said at least said first and second contact members contacts its respective portion of the interior surface of the catch basin, the second of said at least said first and second contact members may continue to rotate in response to the operator's action until said second contact member contacts its respective portion of the interior surface of the catch basin. 8. The cover assembly claimed in claim 7 wherein the clamp member includes a transition member, said transition member connected between said at least said first and second contact members. 9. The cover claimed in claim 8 wherein the ability of said at least said first and second contact members to rotate independently of each other after the first contact member contacts its respective portion of the interior surface of the catch basin is due, at least in part, to the fact that the transition member connected between each said contact member is of a predetermined thickness.
