Abstract
A handle support mechanism is designed for attachment to a door lock, preferably the exterior of a mortise lock, that has two handles driven back to an initial position with a common return spring after either handle is used. The support mechanism prevents the unused handle from drooping or rotating when the common return spring is compressed as the opposite handle is turned. The support mechanism includes first and second friction discs trapped between the exterior of the mortise lock and the legs of a U-shaped spring bracket. The spring bracket applies an inward spring pressure to prevent a friction disc and its corresponding handle from turning when the other handle is in use. The handle support mechanism improves visual appearance and is particularly suitable for retrofit installations, lever handle designs and mortise locks with independent switch sensors on the two handles that notify a monitoring system as to which handle was turned to open a monitored door.
