Abstract
A safety gate system having an electronic display for seamless integration into a barrier with electronic display capabilities. The safety gate system includes a post and a gate hinged to the post. The gate face and post carry electronic display modules which appear when the gate is closed, as continuous with and seamlessly integrated into the display of the barrier. Preferably, the hinges are four-bar hinges, most preferably two sets of paired four-bar hinges. The safety gate also includes a lower chase or sill which allows both signal wiring and power to pass under the gate. Braced rear legs compensate for the cantilever forces of the gates when open. A latch, preferably an electromagnetic latch, auto-releases in response to a pre-set sufficient force level, such as arising crowd surge forces, being applied to the gate, as well as being remotely releasable.
