A glass cover for an enclosure is mounted over an opening in the enclosure by a pair of recessed hinges, each of which includes a hinged body. There are two slots in each hinged body. Each hinged body is positioned within a recess in the enclosure wall. The hinge also includes a frictional member positioned in one of the slots in the hinged body, and a cover holder. Two pins couple the cover holder to the hinge body. One of the pins is coupled to the friction member; this pin passes through one of the slots into a socket in the friction member. The other pin is positioned within the other slot. The frictional member engages a portion of the hinged body defining the perimeter of the slot in which it is disposed. As the cover is raised and lowered, the frictional member rides along this slot. The frictional forces between the side walls of the slot and the friction member are such that the cover remains stationary when the person lifting the cover releases his or her grip. A cover-leveling system is also provided, and the shape of the hinge body is designed for easy installation.

DETAILED DESCRIPTION Briefly, the hinge of this invention is adapted to be mounted within a recess in an enclosure wall and it comprises (a) a hinge body having first and second slots therein, (b) a friction member disposed within the first slot and in frictional engagement with a portion of the hinged body defining the perimeter of the first slot, (c) means for holding the cover, and (d) a pair of pin means coupling the cover holding means to the hinged body, one of the pin means being coupled to the frictional member and the other being disposed within the second slot.
The hinge body has three edges, one of the edges being arcuately shaped and the other two being generally straight.
The edges abut each other at their ends such that one of the straight edges abuts one of the ends of the arcuately shaped edge and the other of said straight edges abuts the opposite end of the arcuately shaped edge.
The two straight edges abut each other at their ends remote from the arcuately shaped edge to form an angle therebetween of approximately 90.
degree.
.
Preferably, the arcuately shaped edge encompases approximately a semi-circle.
This shaped hinge body is designed to fit easily into the corner of the enclosure where two of the enclosure walls meet.
The recess in one of the walls will have a depth about equal to the thickness of the hinge body and have two open sides of a length approximately equal to the straight edges of the hinge body and an arcuately shaped rim at opposed ends of the opened sides.
One of the open sides will be in an exposed edge surface of the wall carrying the recess and the other open side is in the concealed edge surface of the wall carrying the recess and will be disposed along the corner.
The hinge body is seated in the recess with one straight edge adjacent the open side of the recess which lies along the corner, and the other straight edge is adjacent the open side in the exposed edge surface and is approximately flush with said exposed edge surface.
The arcuately shaped edge of the hinge body is adjacent the arcuate rim of the recess
