Abstract:
Electrically operated folding operable walls controlled by an electrical operation circuit of the type having a key switch, a control panel, an extend limit switch, a stack limit switch, control relays and a motor, in which the invention being a safety system comprises:a) Means for providing a lead end sensing edge mounted on the leading edge of the lead (first) panel using an aluminum or PVC mounting channel, mounted in a vertical configuration from the bottom of the panel to six feet in height placing the sensor in the best possible location to allow it to strike an object or person while the motorized operable wall is in a forward motion thereby applying pressure to the lead edge sensor; b) Means for providing one or two floor mats, placed under the partition, in the stack area to allow an object placed on or a person stepping on said mats thereby applying pressure, to activate the internal strip switch while the motorized operable wall is in a reverse motion; c) Means for transmitting a radio frequency (RF) signal from either the lead end sensing edge or the floor mats to a remote receiver, when either the lead sensing edge has made contact with a person or object or a person has stepped on, or an object has been placed on the floor mats; d) Means for shutting down the electrical operation circuit of said folding operable walls when a person or object comes in contact with the lead sensing edge, or a person steps on, or an object is placed on the floor mats, said shutting down means includes a control unit electrically connected between the control panel of the electrical operation circuit and the RF receiver, which will turn off the electrical operation-circuit upon receiving an RF signal from either RF transmitter located at the aforementioned lead sensing edge or floor mats; e) Means for restarting the electrical operation circuit of said folding operable walls after the person or object has been removed from the path of the folding operable wall; said restarting means includes a reset control switch, either button or key operated, mounted on the wall in proximity to the operable folding wall's original operating switch which, when activated, will reactivate the electrical operation circuit allowing the folding operable wall to be operated again.
