Abstract
An emergency exit sign includes a support assembly which permits rotation of lighting heads, about an upright axis, through an angle greater than 180°. 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.
Claims14
An exit sign comprising:
- a housing having a front face and a rear face with a peripheral edge therebetween, said housing being adapted to receive a lighting system including an illumination source and a power source;
- symbols located on said front face adapted to be illuminated by the lighting system;
- a support assembly mounted to said peripheral edge, said support assembly including a support arm defining a first axis;
- a freely rotatable lighting head supported by said support arm for movement to any one of a plurality of selectable, discreet positions through an angle greater than 180° about the first axis;
- and
- means for enabling sliding adjustment of said lighting head relative to said support arm.

- symbols located on said front face adapted to be illuminated by the lighting system;
- a support assembly mounted to said peripheral edge, said support assembly including a support arm defining a first axis;
- a lighting head;
- and
- means for attaching the lighting head to the support assembly for rotation about first, second and third distinct axes, while permitting adjustment of said lighting head about the first axis through an angle greater than 180°, wherein said attaching means comprises a joint element attached to the support assembly for rotation about the first axis and a connector attached to the joint element for rotation about the second axis, said lighting head being directly attached to the connector for movement about the third axis, wherein said lighting head is provided with an elongated recess into which the connector projects such that the lighting head is slidable relative to the connector.
