Abstract: An emergency unlocking device for locking and unlocking systems for swinging sliding doors, in particular of rail vehicles. The emergency unlocking device has a traction device that engages on a first spring-loaded pivoted lever that is connected via a second lever to a third lever. The third lever is attached to the axial shaft of a spring-loaded rotary magnet and has elongate holes in which a bolt is displaceably mounted. When the traction device is subjected to tensile stress, the bolt engages with a fourth lever that is pivotably mounted on a shaft, and moves the fourth lever. The fourth lever is operatively connected via a coupling rod and deflection unit to a locking rod that moves the vertical direction. A rod, via which a force component that brings about the locking and unlocking of the door leaves can be applied, engages on the fourth lever.

Abstract: A relay rack includes a base including first and second base brackets. Each base bracket has a vertical base flange attached integrally to a horizontal base flange. First and second support brackets are connected to each base bracket. Each support bracket has a single vertical support and a single horizontal support connected to the vertical support. The support brackets may also include a single vertical end support adapted to be connected to the vertical flange of the base bracket. The vertical support extends along a substantially vertical plane that forms a dihedral angle of less than 90 degrees with the plane of the vertical base flange. In a direction in which the horizontal base flange extends from the vertical base flange, the vertical supports on each base bracket extend convergently toward one another.

Abstract: A portable pet portal insert for a sliding patio door includes separate top, center, and bottom modules that can be assembled together through use of tongue and groove fittings therebetween, with the bottom module having a cutout portion adapted for receiving a pet portal, the pet portal including a pivotal flap, a cam operated lock for preventing movement of the flap away from an associated frame, and a weather seal mechanism.
