Includes Piston And Cylinder Attached To Support By Cable Patents (Class 187/347)
  • Patent number: 10351388
    Abstract: A first adjustable cabin rail guide is moveably attached to a structural member of an elevator cabin. A second adjustable cabin rail guide is similarly moveably attached to a structural member of an elevator cabin. The first and second adjustable cabin rail guides cooperate together to reduce sound and increase operational efficiency. A piece of textile or similar material is attached to a tube forming the friction portion of the guide. The use of textile thereby reduces the sound of the travel upon the rail associated with the inner portion of the elevator cylinder as the cabin transits therein.

  • Patent number: 8519263
    Abstract: A below ground component management system includes a base plate disposed below a ground surface, a sleeve connected to the base plate and extending substantially perpendicular thereto toward the ground surface, and a cover sealably connected to an upper opening of the sleeve to form a substantially fluid-tight compartment with the base plate and the sleeve. The system also includes a component rack disposed within the compartment, and an actuator assembly configured to pass at least a portion of the rack through the opening. The actuator assembly includes a bracket, and first and second cylinders connected to the bracket. The first cylinder has a piston extending toward the base plate and the second cylinder has a piston extending toward the opening.

  • Patent number: 6662905
    Abstract: An elevator includes a special propelling fluid dynamic device which uses as a plunger the duly balanced car counterweight. The car conveys people and things upwards and downwards within a vertical conduit or hoistway supported by a cable extending to an upper pulley. When changing the direction, a counterweight is extended to balance the car. The pulley is supported from the hoistway walls and is kept in a freely-rotating condition while the balanced counterweight is a hollow piston-counterweight, accommodated in the cylinder vertically disposed in the hoistway itself and adjacent to the car. Both are integral with the propelling fluid dynamic device that produces the upward and downward movements of the car, which is completed with a circuit having a fluid flow conduit and a driving pump coupled to the valve mechanism.

  • Publication number: 20030217895
    Abstract: In the buffer device for an elevator of the present invention, a hydraulic buffer that alleviates shock generated when a traveling body impacts a bottom of a hoistway is arranged at the bottom of the hoistway. Provided between the traveling body and the bottom of the hoistway is an elastic member that is elastically deformed and that alleviates the shock generated by the impact of the traveling body with the hydraulic buffer. The elastic member is arranged so that when elastically deformed, almost the whole thereof is positioned within a range of a vertical dimension of the hydraulic buffer.

  • Patent number: 5641041
    Abstract: A vibration-damping device is interposed between a carriage and a lifting rope. The vibration-damping device comprises a spring extended in a compressed state between a spring shoe on the lifting rope side and a spring shoe on the carriage side located above the first-mentioned spring shoe, and a damper extended between the spring shoe on the lifting rope side and the spring shoe on the carriage side, and upper and lower ends of the damper are pivotally mounted on the spring shoe on the lifting rope side and the spring shoe on the carriage side.

  • Patent number: 5549180
    Abstract: An escape apparatus is designed for placement adjacent to an exterior entrance of a multi-story residence or other building. The escape apparatus includes an escape platform and cage which is attached to and supported by a sleeve which extends around the periphery of a vertically oriented stationary hollow column. The sleeve is movable upward and downward along the column exterior. A pair of cables are connected to the sleeve and extend from the sleeve upward and over a respective pair of sheaves positioned atop the vertical column and then into the column interior where they are connected to a speed control piston-counterweight. The column is preferably filled with liquid, such as a water and anti-freeze mixture, and the piston-counterweight has an aperture extending therethrough from top to bottom to allow liquid to flow from one side of the piston-counterweight to the other and a valve operating within the aperture to further regulate the rate of ascent of the piston-counterweight.
