Gravity-based locking hinge

Abstract:

A hinge includes a fixed component defining a vertical axis. The fixed component includes a first support surface with a circular lug path and a first recess formed in the first support surface at an end of the circular lug path. The hinge also includes a pivotable component pivotable about the vertical axis and translationally movable along the vertical axis. The pivotable component includes a first lug extending from the pivotable component in a first direction. The first recess receives and constrains movement of the first lug. The first support surface supports the first lug along the circular lug path and constrains translational movement of the pivotable component in the first direction as the pivotable component pivots about the vertical axis. In the open position, the pivotable component is translationally movable in the first direction and the first lug is receivable into the first recess.
