Emergency exit sign

An emergency exit sign is incorporated directly into the floor adjacent an emergency exit door. The emergency exit sign includes visual and tactile properties that allow the sign to be read on a day to day basis by those walking through the doorway. The tactile properties of the sign also allow the sign to be read by those on the floor in an emergency situation such as when the room or hallway is filled with smoke. The tactile properties of the sign may also be used by those trying to find the doorway in a dark room. Further, the tactile properties of the sign are used on a day to day basis as people walk over the sign to reinforce the person's memory of the location of the emergency exit door.

Exit sign with rotatable lighting heads

An emergency exit sign includes a support assembly which permits rotation of lighting heads, about an upright axis, through an angle greater than 180.degree.. A freely rotatable joint element is used to maintain the lighting heads, in cooperation with mating facets, in various positions without the need for mechanical fasteners. The lighting heads are also attached to a snap connector which, enables the lighting head to be shifted about an arcuate axis, as well as rotated about a still further axis which is substantially perpendicular to the upright axis.

Exit sign and emergency light testing-clamp

A clamping device is used to push a test button on an exit sign or emergency light. The clamp can be attached without damaging various signs and lights. The clamp includes a channel (40), which guides an adjustable protruding object to push a test button located on the bottom of the exit sign or emergency light. The clamp can test exit signs and emergency lights that are wall mounted by modifying the base (10) with a flat back (130). The clamp can also be used in conjunction with an extension arm (90) to reach test buttons located at a distance from the bottom.

Pivotable overhead lighted exit sign

An overhead lighted exit sign and mounting includes a substantially rectangular box shaped sign housing with an electric light therein. A substantially cylindrically shaped two part hollow hinge is mounted on the top wall of the housing with one part fixed to the housing. The second part of the hinge is secured to a plate adapted to be secured to an overhead electrical box. Apertures are formed in the top wall of the housing, the two parts of the hinge and the plate to allow electrical wires to pass from the electrical box to the electric light within the sign without being exposed. The hinge allows the sign to pivot out of the way in the event that it is struck by an object being carried therebelow without the sign being broken from its support or otherwise being damaged.
