Abstract
Abstract The invention is directed to a hinge assembly for pivotably interconnecting a frame and a glass door of a refrigerated display case. The hinge assembly is pivotable about a horizontal axis and includes a hinge movable between a first position and a second position. The hinge includes a spring biasing device for biasing the hinge to the first position or second position. A clamp is connected to the hinge and holds the glass door using only frictional force.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
184 words
A refrigerated display case, comprising: a frame; a glass door; and a hinge assembly interconnecting said frame and said glass door, said hinge assembly pivoting about a horizontal axis and including: a hinge movable between a first position and a second position, said hinge including a spring biasing means for biasing said hinge to one of said first position and said second position; and a clamp including a first part connected to said hinge and a second part adjustably connected to said first part, said first part and said second part frictionally engaging said glass door therebetween, said hinge including a mounting bracket, a pivot plate mounted on said clamp, a first pivot means pivotally connecting the pivot plate to the mounting bracket, a pressure plate, second pivot means pivotally connecting the pressure plate to the pivot plate, said pressure plate carrying an elongated planar face offset from said second pivot means, said spring bias means including a coil spring mounted on said mounting bracket, and means for transferring the force of said coil spring to the elongated planar face of said pressure plate.
Claim 2
Dependent Claim
184 words
A refrigerated display case, comprising: a frame; a glass door; and a hinge assembly interconnecting said frame and said glass door, said hinge assembly pivoting about a horizontal axis and including: a hinge movable between a first position and a second position, said hinge including a spring biasing means for biasing said hinge to one of said first position and said second position; and a clamp including a first part connected to said hinge and a second part adjustably connected to said first part, said first part and said second part frictionally engaging said glass door therebetween, said hinge including a mounting bracket, a pivot plate mounted on said clamp, a first pivot means pivotally connecting the pivot plate to the mounting bracket, a pressure plate, second pivot means pivotally connecting the pressure plate to the pivot plate, said pressure plate carrying an elongated planar face offset from said second pivot means, said spring bias means including a coil spring mounted on said mounting bracket, and means for transferring the force of said coil spring to the elongated planar face of said pressure plate.
