Abstract
A locking device for pivotally interconnecting a closure to a support and locking the closure in an open position relative to the support. The interlocking device interconnects the closure and support about a vertical axis, so that the closure can pivot about this axis and open and close relative to the support. The interlocking mechanism includes a locking mechanism having two engageable locking ratchet members. One ratchet member is fixedly coupled to the closure, and the second ratchet member is coupled to the support for movement along the vertical axis. The locking mechanism also has a spring which biases the ratchet members together into engagement with each other. Both ratchet members have compatible teeth with a ramping surface and a stopping surface for limiting the pivotal movement of the closure to a first direction and locking the closure in an open position. The releasing mechanism disengages the ratchet members, which allows the closure to be closed. The releasing mechanism may be manually operated or electrically operated through the use of a solenoid. The engaging mechanism causes the ratchet members to reengage when the closure is closed.
