E05F 15/02
US Classification:

49340, 49141, 49341, 49344
Abstract:

A locking mechanism () for use with a pneumatic cylinder/differential engine for a power-operated door including a locking rod (), a plunger () associated with the locking rod () to cause extension and retraction of the locking rod () with respect to a door opening/closing gear (), and a spring member () associated with the plunger () for maintaining the plunger () and the locking rod () in an extended position during a door closed position. An aperture () is located through a sidewall portion of the gear hub () which is capable of receiving an end () of the locking rod () when the locking rod is in an extended position to lock the door in a door closed position. The invention also includes an emergency door opening mechanism enabling manual opening of the doors in case of an emergency.

US Patent:

20020092236, Jul 18, 2002
Filed:

Sep 12, 2001
Appl. No.:

09/951492
Inventors:

Steven Heffner - La Grange IL, US
Peter Heidrich - Niles IL, US
Robert Oakley - Chicago IL, US
International Classification:

E05F011/00
US Classification:

049/324000, 049/362000
Abstract:

A mechanical power conversion device for receiving rotary power from a rotary power supply and delivering two independent power outputs, the conversion device having: a drive screw connectable to the rotary power supply, a drive nut engaging the drive screw to receive a drive nut axial force and drive nut torsion therefrom, the drive nut axial force being parallel to the drive screw and the drive nut torsion being about an axis of the drive screw. One of the two independent power outputs is connected to the drive nut to receive the drive nut axial force and the second is connected to the drive nut to receive the drive nut torsion so that power from the rotary power supply flows to either or both of the first independent power output and the second independent power output.

Appl. No.:

17/610650
Inventors:

- Pittsburgh PA, US
Peter Heidrich - Des Plaines IL, US
International Classification:

E05D 15/10
E05F 15/646
Abstract:

A system with a base may be mounted on a vehicle, and a carriage assembly that may be movably connected to the base and may move with respect to the base. The carriage assembly may include a motor including a motor output shaft and motor housing, and a driving mechanism may couple to a door and to the motor output shaft or the motor housing. The carriage assembly may also include a coordination bar may be coupled to the motor output shaft or the motor housing, the motor output shaft or the motor housing may rotate the coordination bar responsive to operation of the motor. At least one linkage assembly may extend or retract to move the carriage assembly to move the door between an open position and a closed position based on rotation of the coordination bar.
