    Abstract: A garage door operator is disclosed which has a motor-driven screw nearly enclosed within a guide, and a partial nut is guided by this guide means and moved longitudinally therealong by engagement with the rotating screw. The partial nut is adapted to be connected to a garage door to open and close the same. In order to shorten the package in which the garage door opener is shipped, the screw and guide means are in two or more parts and adapted to be coupled together to make an operative long screw and an operative long guide means. The screw parts, instead of being connected together at the factory by a double pivot connection, are shipped to the customer in a disconnected condition but one in which the coupling readily may be connected in a proper phase to avoid mismatch of the threads. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

    Abstract: The invention relates to a power door opener, such as the type of opener used for opening overhead garage doors includes a worm gear rod having a major thread and a carrier member coupled to the door and releasably engageable with the major thread for moving the door between open and closed positions as the rod rotates. A second thread whose pitch is smaller than the major thread is formed on the rod and on a portion thereof located between a pair of spaced apart limit switches. A control member threadably engages the second thread for movement between the limit switches as the rod rotates for terminating motor operation as the door moves into its open and closed positions. The carrier member is mounted for radial movement into and out of engagement with the major thread to permit manual operation of the door.

    Abstract: An automatic door operator includes a lead screw having a first end connected to an output end of an actuating unit and a second end extending away from the output end. A lead screw nut is attached to the lead screw. A slider is attached to the lead screw nut. The slider is provided with a rack portion extending in a direction parallel to an axial direction of the lead screw, and during a movement of the lead screw nut, a length of an overlap of the rack portion and the lead screw in the axial direction varies. The operator includes a housing having a guide hole configured to be slidably engaged with the slider and an output shaft is mounted in a mounting hole disposed on the housing. The output shaft has a gear portion positioned in the guide hole and engaged with the rack portion.
