Abstract
A display case includes a housing partially surrounding a display space, a door pivotably coupled to the housing and cooperating with the housing to further enclose the display space, and a hinge assembly for pivotably coupling the door to the housing. The hinge assembly includes a biasing member applying a biasing force on the door and a gear drive for adjusting a pre-tension force on the biasing member.
Claims13
A display case comprising:
- a main housing partially enclosing a display space and defining an opening;
- a support member fixedly coupled to the main housing;
- a second housing including a first gear, the second housing coupled to the support member;
- a second gear supported for rotation by the support member and in meshing relationship with the first gear, rotation of the second gear producing a corresponding rotation of the first gear and the second housing;
- a door pin defining a door axis, the door pin supported for rotation about the door axis by the second housing;
- a biasing member connected to the door pin and the second housing and operable to provide a biasing force to the door pin, the biasing force being adjusted in response to the rotation of the second housing;
- and
- a door coupled to the door pin for co-rotation therewith, wherein the biasing force biases the door toward a closed position, and wherein the second housing, the biasing member, the first gear, and the second gear are disposed completely outside of the door and supported by a flange, and a portion of the door pin is received by the door to facilitate movement of the door with respect to the shell.
