Patent number: 8123002Abstract: A system and method for minimizing compensation rope sway by altering the natural frequency of compensation ropes using servo actuators. The rope sway may be minimized by moving the compensation sheave to adjust the tension of the compensation rope or adjusting the position of the termination of a compensation rope to account for changes in the position of a structure. Servo actuators may also be used to re-level the elevator car to account for rope stretch.Type: GrantFiled: September 15, 2008Date of Patent: February 28, 2012Assignee: Thyssenkrupp Elevator Capital CorporationInventors: Rory S. Smith, Stefan Kaczmarczyk, Jim Nickerson, Patrick M. Bass

Patent number: 7261184Abstract: The invention comprises a support structure for an elevator system comprising a pit channel module having a first leg and a second leg connected at a corner, a header module having three sides forming a triangle which is disposed in a horizontal plane above the pit channel module, and pairs of car guide rails and counterweight guide rails extending vertically from the pit channel module to the header module. Vertical forces generated within the system are transferred from the rails through the pit channel module and into a foundation so that at least substantially no vertical load forces are imparted on the building structure which the system serves.Type: GrantFiled: January 28, 2003Date of Patent: August 28, 2007Assignee: Thyssen Elevator Capital Corp.Inventors: Patrick M. Bass, John W. Koshak

Patent number: 6854164Abstract: A termination device for an aramid-based elevator rope comprises a socket having a tapered internal passageway adapted to receive a wedge and a rope. The passageway has first and second semi-cylindrical rope engaging surfaces. The wedge has a peripheral groove having a variable radius of curvature. The device clamps the length of rope between linear portions of the wedge and the rope engaging surfaces of the socket with a substantially uniform application of force on the cross-section of the rope.Type: GrantFiled: January 28, 2003Date of Patent: February 15, 2005Assignee: Thyssen Elevator Capital CorpInventors: Patrick M. Bass, Robert Sweet

Patent number: 6845849Abstract: A height adjustment assembly connecting an elevator door to an elevator door hanger comprises a door bracket, a plurality of door clip receiving sections and corresponding number of door clips. Each door clip comprises upper and lower fins, side fins, and an oblique slot disposed centrally between the fins. Each oblique slot is aligned with an aperture in the receiving sections, and the upper and lower fins slidably engage corresponding slots in the receiving sections. A fastener inserted into the oblique slot in the door clip and the aperture in the door bracket holds the clip and the bracket onto the door hanger in a friction hold mode. The height of the door may be adjusted by moving the door clips laterally in the slots.Type: GrantFiled: January 21, 2003Date of Patent: January 25, 2005Assignee: Thyssen Elevator Capital CorpInventor: Patrick M. Bass

Patent number: 6830355Abstract: An elevator cab lighting assembly comprising a refractive sheet mounted on the interior of the elevator cab. A light source is mounted at and conducts light into an outer edge of the refractive sheet. The light received at the outer edge of the travels along the refractive sheet and passes out of the planar surface and inner edge of the sheet exposed within the interior of the cab. The refractive sheet may be randomly sanded or sandblasted to provide diffuse light. The sheet may be etched or routed in standard or custom designs to provide accent highlighting. The lighting assembly is housed within a transom assembly that may be accessed from the exterior of the cab.Type: GrantFiled: January 9, 2003Date of Patent: December 14, 2004Assignee: Thyssen Elevator Capital Corp.Inventors: Patrick M. Bass, John W. Koshak, Aranggi Soemardjan

Publication number: 20040093828Abstract: An elevator cab door having a honeycomb core comprises an elevator door frame adapted for attachment to the entryway of an elevator cab. The door frame has a front skin panel and a rear skin, and a core comprising a plurality of honeycomb cells sandwiched between the front and rear skins. The door assembly components, including the frame, core and the skins are formed from a light, strong material such as aluminum. The structure is lightweight, easily adaptable to varying opening and closing velocities, and less prone to imparting dangerous impact loads on passengers in case of hazardous situations.Type: ApplicationFiled: November 20, 2002Publication date: May 20, 2004Inventors: Rory Stephen Smith, Patrick M. Bass

Publication number: 20040026676Abstract: The invention provides modular drive and deflector sheave assemblies for raising and lowering elevator cars and for deflecting a support rope or cable in different directions with minimal wear. The drive sheave assemblies of the invention provide sufficient traction between a support rope, e.g., nylon-jacketed Kevlar suspension rope, and sheave to raise and lower elevator cars without requiring more than 180° of contact between the rope and drive sheave. Such a drive sheave assembly can advantageously have a non-rope-pinching groove, thereby minimizing wear on the rope and vibration during operation.Type: ApplicationFiled: March 19, 2003Publication date: February 12, 2004Inventors: Rory Stephen Smith, Patrick M. Bass, Craig Bull, San Aranggi Soemardjan

Patent number: 6659514Abstract: An electromechanical interlock for a swinging elevator door is disclosed. The interlock comprises a pivotal hook member that may be attached to a swinging elevator door. The hook has a beak end and may pivot between a locked and an unlocked position. Disposed on the beak end is an electrical conductor. When the interlock is in the locked position, the beak end engages a lug and the conductor contacts electrical contacts to complete an electrical circuit. A solenoid pivots the hook from a locked position to an unlocked position. The electromechanical interlock may be adapted for use with sliding elevator doors as well as swinging doors.Type: GrantFiled: May 4, 2001Date of Patent: December 9, 2003Assignee: Thyssen Elevator Capital Corp.Inventor: Patrick M.
