Power bus and structure for a barrier movement operator
A barrier movement operator with improved mounting and power distribution capabilities is disclosed. The disclosed system includes an elongate member mounted from an overhead structure in a substantially horizontal manner. A head end of a barrier movement operator may be supported by the elongate member and the elongate member may be used to mount accessory devices such as lights and extension cords, and to provide mains voltage to the mounted accessories.
1. A support apparatus for overhead mounting of a barrier movement operator having a width, the barrier movement operator including a controller, the support apparatus comprising:
a semi rigid elongate member having a length greater than the width of the barrier movement operator;
a plurality of upper supports connected to the elongate member for attaching the elongate member to an overhead structure and suspending the elongate member from the overhead structure so as to be separate from the overhead structure, the elongate member being substantially rigidly connected to the overhead structure in a substantially horizontal plane;
connection apparatus for connecting the elongate member to the barrier movement operator;
a plurality of electrically powered accessories supported by the elongate member;
a power distribution system responsive to the controller for distributing electrical power to the electrically powered accessories; and
an apparatus for removably connecting the power distribution system to a mains voltage source;
wherein the barrier movement operator provides electrical power to the power distribution system.
2. A support apparatus according to claim 1 wherein the barrier movement operator selectively connects electrical power to the power distribution system.
