The display case of claim 1, wherein the second housing includes a bore receiving at least a portion of the door pin, wherein the biasing member is a torsional coil spring positioned within the bore between the second housing and the door pin. 5. The display case of claim 1, wherein the support member includes an elongated sleeve having a bore, wherein the second housing is positioned within the bore of the sleeve. 6. The display case of claim 1, wherein the second gear is a worm gear mounted on a gear shaft, rotation of the gear shaft driving the first gear to rotate. 7. The display case of claim 1, wherein the second gear is rotatable about an axis that is offset from and perpendicular to the door axis. 8. 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; anda door coupled to the door pin for co-rotation therewith, wherein the biasing force biases the door toward a closed position,wherein the second housing, the biasing member, the first gear, and the second gear are disposed completely outside of the door and a portion of the pin is received by the door to facilitate movement of the door with respect to the shell. 9. The display case of claim 8, wherein the second housing and the first gear are rotatable about the door axis, and the biasing member exerts a biasing force about the door axis, wherein the second gear is rotatable about an axis that is perpendicular to the door axis. 10. The display case of claim 8, wherein the second housing includes a bore receiving at least a portion of the door pin, wherein the biasing member is a torsional coil spring positioned within the bore between the second housing and the door pin. 11. The display case of claim 8, wherein the support member includes an elongated sleeve having a bore, wherein the second housing is positioned within the bore of the sleeve. 12. The display case of claim 8, wherein the second gear is a worm gear mounted on a gear shaft, rotation of the gear shaft driving the first gear to rotate. 13.
