Patent ID: 7048468

Claim:
Cover arrangement for a channel arrangement that can be installed in the ground and opened, comprising a cover, and a frame defining a bearing surface, wherein the cover can be set on the bearing surface and coupled to the frame so as to be pivotable about an axis of rotation, the cover being tiltable toward two sides without the use of tools, by two oppositely disposed hinges each comprising a rotation and fixation device, wherein the hinges are configured so that the cover is liftable vertically upward, thus disengaging the rotation and fixation devices without tilting movement of the cover with respect to the frame, wherein each rotation and fixation device comprises: a downwardly bent, hook-shaped pivot element connected to the cover, a pivot peg connected to the frame and shaped to correspond with the pivot element, about which the pivot element can be rotated, and which is disposed with respect to the axis of rotation in such a way that when the cover is in a completely closed position, the pivot element can be lifted away from the pivot peg; a guide bar disposed below the pivot peg such that during the tilting movement of the cover, the hook-shaped pivot element is guided between the pivot peg and the guide bar in a form-fitting manner, wherein the guide bar and the pivot peg are constructed and disposed such that during the rotational movement made by the cover due to lifting of the opposite side of the cover, a downwardly bent end of the pivot element comes into contact with the upper surface of the guide bar when a first tilt angle between 10° to 20° is reached, and simultaneously a bearing surface of a cover foot is raised away from the bearing surface of the frame.
