Abstract
Abstract The present invention provides a combination door and panic handle for use on the interior side of entrance doors. In one mode of operation the panic handle may be moved inwards towards the door face to unlatch the door. In this mode of operation the door may be opened on the exterior side by use of a key. In an alternative mode of operation, the panic handle is "locked-out" and prevented from moving. In this mode of operation the door is unlatched and the panic handle may be used as a fixed door handle. In the movable mode of operation, pressure may be applied along any portion of the panic handle to facilitate unlatching the door. The operating mechanism of the panic handle is concealed presenting a smooth uncluttered appearance.
