US 8,006,435 B2 · Safety gate system having an electronic display

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.

Dependent claims

A safety gate system for integration into a barrier system with electronic display capabilities so as to allow controlled passage through the barrier system, the system comprising:

a post including a post hinge extension;
a gate having a first end rotatably connected to the post hinge extension with a hinge, and movable between a closed position disallowing passage through the barrier system and an open position allowing passage through the barrier system, wherein the hinge is configured such that a back surface of the gate covers the post hinge extension when the gate is in the closed position with a front surface of the gate flush with an exposed front surface of the post, and the first end of the gate faces the post hinge extension when the gate is in an open state;
and
a latch system, the latch system holding the gate in the closed position, wherein the gate has a face providing an electronic display, which electronic display appears substantially seamlessly integrated into the electronic display capabilities of the barrier system.

1 more element

A safety gate system having an electronic display comprising:

a first post, the first post including a hinge extension;
a second post spaced apart from the first post, the second post having a hinge extension;
a first gate, the first gate pivotally/hingedly carried by at least one four-bar hinge between the first gate and the hinge extension of the first post, wherein the at least one four-bar hinge is configured such that a back surface of the first gate covers the hinge extension when the first gate is in a closed position with a front surface of the first gate flush with an exposed front surface of the first post, and a hinged end surface of the first gate faces the hinge extension when the first gate is in an open state;
a second gate, the second gate pivotally/hingedly carried by at least one four-bar hinge between the second gate and the hinge extension of the second post, wherein the at least one four-bar hinge is configured such that a back surface of the second gate covers the hinge extension when the second gate is in a closed position with a front surface of the second gate flush with an exposed front surface of the second post, and a hinged end surface of the second gate faces the hinge extension when the second gate is in an open state;
a magnetic latch between the first gate and the second gate, the magnetic latch holding the first and second gates in a mutually closed condition/position and yielding to a sufficient force to release the gates to an open condition, wherein the first post, the second post, and the first gate and the second gate, when in mutually closed condition between the first and second posts, together present a front face having a grid of rows and columns for accepting electronic display modules;
and
a plurality of electronic display modules populating the grid and connected to a power and signaling source, such that an electronic display may be presented on the front face.
