Abstract
A light box display configured for frontal access to change out graphics and to perform maintenance tasks. This is accomplished in the present invention while assuring that the graphics is held in a state of moderate tension to retain the graphics in a flat and properly oriented configuration. In the preferred embodiment, the light box comprises a moveable interior frame to which the graphics sheet and diffuser are both secured. The moveable interior frame rests on a plurality of upper and lower slides which facilitate movement of the inner frame. Such movement is controlled, in part, by at least one pneumatic piston which biases the frame toward the front of the light box and provides a mechanical lock that holds the frame in its rearward position to facilitate frontal access. The graphics sheet is held in place along the top and bottom front peripheral edges of the moveable frame by a plurality of spring-biased wire connection members within roller guides. One end of each wire member is attached to the rear peripheral surface of the moveable inner frame and the other end is threaded through a grommeted hole along the outer edge of the graphics sheet. Side spring-biased wire connection members are also provided.
