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.
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.
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.
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.
