ABSTRACT:
A shield lock assembly for shielding securing members engaging a rigid frame. The lock assembly includes a shield member which is secured to a rigid frame through a fastener. The shield member further passes over and covers at least one of the securing members. A lock housing is movably mounted to the shield member and is displaceable to a first locking position which covers the fastener to prevent disengagement of the fastener from the rigid frame. The lock housing is movable to a second unlocking position which exposes the fastener and allows disengagement of the fastener from the rigid frame to permit removal of the shield member thus exposing the covered securing members.
