Abstract
A gate is provided for use as a closure device within a doorway and includes an L-shaped frame member which may be positioned in stationary relationship to the doorway and a panel member which is pivotally mounted to the frame member. The panel member carries a latching mechanism including a latch for engaging a lower horizontal extension of the frame member to prevent pivotal movement of the panel portion. In addition, a contact member is provided for contacting a surface of the doorway when the latch member is engaged with the frame. A release lever is provided for moving the contact member out of engagement to allow pivotal movement of the panel relative to the frame. A locking member is provided for preventing operation of the lever such that the locking member must be operated simultaneously with the lever in order to release the contact member.
