  • Patent number: 6488125
    Abstract: An elevator has a rope connected at a first end thereof to a top of a car and at a second end thereof to a top of a counterweight and guided and driven by a sheave that is rotated by a motor. A compensating rope suspends between the car and the counterweight. The compensating rope has a curving portion, a first linear portion on the car side of the curving portion, and a second linear portion on the counterweight side of the curving portion for compensating an imbalance of weight between a portion of the rope on the car side of the sheave and a portion of the rope on the counterweight side of the sheave. A first guide is arranged to guide the first linear portion and the second linear portion, and a second guide is arranged below the first guide and positioned between lines extending from the first linear portion and the second linear portion for guiding the curving portion of the compensating rope. A frame is arranged in a pit of an elevator shaft for supporting the first guide and the second guide.

  • Patent number: 6435316
    Abstract: In a rope supporting apparatus for an elevator, a column-like body along a guide rail provided within a hoist way is mounted on the guide rail through support bodies located at upper and lower ends of the guide rail. A rope end fixing member to which an end of a rope is fixed is fastened to the column-like body. The column-like body has a higher bending strength than the guide rail. Since the support bodies at both upper and lower ends of the column-like body are disposed with a sufficient distance between them, a pivoting reactive force, which is a load generated in the support bodies in a direction perpendicular to a center axis of the rail, becomes small, and any bending moment applied to the guide rail by the pivoting reactive force is smaller than the bending moment applied to the column-like body.

  • Patent number: 6267205
    Abstract: An elevator system includes a magnetic guide that dampens vibration of a flat rope that move the car and counterweight up and down in the hoistway. The flat rope is guided through an opening in the magnetic guide between a pair of ferromagnetic flux concentrators having a set of teeth. The flux concentrators concentrate a centralizing magnetic flux that centers the ferromagnetic wires of the rope between each tooth. As the centralizing force acts on each ferromagnetic wire, the flat rope will be magnetically laterally centered within the opening of the magnetic guide and vibration of the flat rope is accordingly dampened. In one example implementation of this invention, the magnetic guide is slideably mounted on a slide assembly in response to rope migration.

  • Patent number: 6076638
    Abstract: An elevator for moving passengers from a first, outside level to a second, inside level at a theme park, and for providing themed special effects during the journey is provided. The elevator includes an elevator car divided into a passenger compartment and a special effects equipment compartment. The passenger compartment appears to the unsuspecting passenger to be a conventional elevator. However, at least one partition in the passenger compartment is opaque when the passenger compartment is illuminated and becomes transparent to reveal illuminated special effects when the lighting in the passenger compartment is extinguished. Special effects equipment can include a pair of video projectors for creating a virtual image which appears to be located outside of the elevator car, along with audio speakers for generating appropriate sound to accompany a video sequence for creating an active visual and audio presentation which can be appropriately themed.

  • Patent number: 6073728
    Abstract: A hoisting rope for an elevator includes a plurality of longitudinally spaced, discrete targets retained within the rope. The targets have a characteristic that may be monitored by a device that is responsive to that characteristic. In a particular embodiment, the targets are formed from a magnetically permeable material and the monitoring device responds to changes in the magnetic field as the target passes the monitoring device. In another embodiment, the targets are formed from material that reflects electromagnetic energy. In this embodiment, the monitoring device emits electromagnetic energy and is sensitive to the energy that is reflected back from the target. A method to inspect the hoisting ropes includes the steps of positioning the monitoring device proximate to the hoisting rope, moving the hoisting rope relative to the device, and monitoring the targets to determine the spacing between targets. Changes in spacing are indicative of stretching of the rope, and thereby degradation of the rope.

  • Patent number: 6047792
    Abstract: Disclosed is an elevator having covers capable of minimizing a generation of turbulent flows at upper and lower portions of the elevator cabin so as to reduce noise and vibration during the operation of the elevator. The elevator according to the present invention comprises upper and lower horizontal supporting members made of shaped steels having a L shape in cross section and plate strips, and covers having a dome and a truncated pyramid shape. In the elevator according to the present invention, the covers can temper impacts, due to air flows in a hoistway, against the elevator cabin during the operation of the elevator. As a result, noise and vibration due to the impacts can be reduced.

  • Patent number: 6044933
    Abstract: A drive system for a hydraulic elevator installation (1) without a machine room including an electric motor (15), a hydraulic pump (16), an oil tank (17), valves (18) and a control apparatus (19) mounted in a cabinet (10). The cabinet (10) can be mounted in direct connection with an elevator shaft (2), for example near a shaft door (6), or at any desired location, preferably in the proximity of traffic routes, in work areas or even in passageways, where good accessibility is guaranteed. A double sound insulation of the cabinet (10) and of the oil tank (17) containing the electric motor (15) and the hydraulic pump (16) damps the noise level of the drive system to the extent that the cabinet (10) can be placed at virtually any desired location without the noise developed by the drive system being disturbing in surrounding spaces.

  • Patent number: 5881845
    Abstract: A protective device for an elevator system extends about a rope and extends upward from an elevator car. The protective device blocks contact with the portion of the rope enclosed by the device. As a result, the risk of damage to the ropes caused by a person, such as a mechanic, who is present on the top of the car, is minimized. The invention is particularly advantageous for synthetic ropes that are subject to damage due to contact with abrasive objects or solvents. In one embodiment, the protective device is a tubular structure formed from a rigid, abrasion resistant material. In other embodiments, the protective device is a sheath formed from an abrasion resistant, woven fiber material that extends about the rope.
