This improves response of the vibration inducing equipment.Type: GrantFiled: December 21, 2004Date of Patent: January 1, 2008Assignee: Inventio AGInventors: Josef Husmann, Elena Cortona

Patent number: 7258204Abstract: A guide device guides a load carrier of an elevator installation along a guide surface and comprises a guide element contacting the guide surface and connected by a connecting element with the load carrier such that the guide element is movable relative to the load carrier in a first and/or a second positional range. The connecting element comprises first and second resilient elements in a serial arrangement, wherein movement of the guide element in the first range deforms both resilient elements and movement of the guide element in the second range exclusively deforms the second resilient element. The overall stiffness of the connecting element is a function of the respective position of the guide element. Stiffness of the second resilient element increases during compression in the second range, wherein the overall stiffness is substantially constant at a transition between the first and the second ranges.Type: GrantFiled: April 29, 2004Date of Patent: August 21, 2007Assignee: Inventio AGInventor: Yvan Kurzo

Patent number: 7168526Abstract: This patent relates to a machine for transporting people and cargo with three-dimensional and infinite movement along properly positioned rails. The main application is for transporting people between two points with different coordinates, for example between one floor of one building and another floor of another building, kilometres away. It is composed essentially of: a set of wheels (1 and 2) that roll on the rails (8 and 9); a cabinet (7) where the people and cargo are transported; a chassis that connects the wheels to a “T” beam (10); this “T” beam (10) connects the chassis to the cabinet (7); electrical engines that move the wheels. The set of parts allows the cabinet to have a non-straight, three-dimensional and infinite movement, the cabinet always being in the vertical position.Type: GrantFiled: November 17, 2004Date of Patent: January 30, 2007Inventor: Vasco Alexandre De Sousa Marreiros Alves

Patent number: 6991069Abstract: A cable elevator includes a car which travels on first parallel guides and a counterweight which travels on second parallel guides, the guides being located in a respective first and second parallel planes. Drive machinery is arranged on an engine mount between the guides, the first guides extending upward past the mount, the second guides ending at the mount. Laterally spaced lower guide elements and laterally spaced upper guide elements are fixed to the car and engage the first guides. A support cable is fixed to the underside of the car so that the car can pass the drive machinery vertically.Type: GrantFiled: December 11, 1998Date of Patent: January 31, 2006Assignee: Inventio AGInventor: Ernst Ach

Patent number: 6786304Abstract: A guide device for an elevator in which a pair of corresponding actuators are controlled by controllers in accordance with information from acceleration sensors, and the force with which guide members are pressed against guide rails is adjusted. Each controller includes a current amplification device and diodes. The diodes selectively output signals from the current amplification device to the pair of actuators.Type: GrantFiled: November 6, 2002Date of Patent: September 7, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenji Utsunomiya, Kenichi Okamoto, Takashi Yumura

Patent number: 6676233Abstract: A storage lift includes two vertically extending tracks mounted to a wall surface such as a garage wall. The tracks guide associated sliding members through vertical motion up and down adjacent the wall. The sliding members are in turn hinged to a platform that serves in alternative embodiments as a storage platform base or a variable-height work surface, and which may also be folded compactly when not in use or during shipping. A full box framework is provided for most applications, and panels are slidable within framework grooves or brackets to fully enclose the platform. A cover may optionally be provided as required. In the preferred embodiment, an electric motor is provided within the storage platform base for motive power, and a key switch control is provided to safely actuate the motor. The electric motor in the preferred embodiment is attached to the tracks through a combination of cables and pulleys, though other techniques are contemplated.Type: GrantFiled: August 29, 2001Date of Patent: January 13, 2004Inventors: Paul E. Evans, John S. Titus

Patent number: 6510925Abstract: Elevator guide shoe for guiding an elevator car along guide rails in an elevator shaft, said guide shoe comprising a supporting frame (2) attached to the elevator car (1) and guides (4) resting against a guide rail (3). According to the invention, the guide shoe comprises an intermediate frame (5), to which the guides (4) are attached. In addition, the supporting frame (2) and the intermediate frame (5) are provided with permanent magnet bars (6a, 6b, 7a, 7b, 8a, 8b) arranged to maintain a horizontal distance between the supporting frame and the intermediate frame. Moreover, the guide shoe comprises vertical suspension (9) between the supporting frame and the intermediate frame to damp the propagation of sound in the structures.Type: GrantFiled: May 5, 2000Date of Patent: January 28, 2003Assignee: Kone CorporationInventor: Johannes De Jong
