Abstract:
A system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position (fig. 7) and a locking position (fig. 8) with the motor assembly blocking movement of the barrier. A bias assembly (170) biases the motor assembly in the operating position (fig. 7) and allows the motor assembly to move toward the locking position (fig.8) when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts (190) on the motor assembly that are engaged by the bias assembly (170). A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.
Abstract:
An operating system which utilizes a multi-functional wall station for a motorized barrier includes an operator for controlling movement of a barrier between various positions. The operator may receive signals from a wireless or wired wall station transmitter, a wireless keyless entry device and/or a portable remote transmitter device. The multi-function wall station provides for selective concealment of certain switches or buttons which are not commonly used in the day-to-day operation of a wall station. For example, the up/down switch may be actuated by a hinged cover which conceals other selected operational buttons and wherein those operational buttons are only accessed upon opening of the hinged cover. The wall station also provides a periodic lighting element so as to easily direct the user to push the hinge cover to initiate up/down movement of the barrier. The multi-function wall station also provides for an operational selection wherein the door may be closed in a normal manner; by an auto-close feature, wherein the door closes after a predetermined period of time; or a RF block mode, wherein the station prevents transmission of any remote radio frequency signals to the operating system. The auto-close feature may only be enabled upon actuation of a keyless entry device so as to allow the user to re-enter the garage in the unfortunate circumstance of being locked out of the garage.
