摘要： A two door assembly (10) for an elevator car (11) includes a high speed door (12) and a low speed door (14) that move between an open and closed position to close the entrance (16) of the elevator car. The doors (12, 14) are retained slidably between a header (18) disposed along the top of the car entrance and a door guide (20) disposed along the bottom of the car entrance (16). A drive mechanism (22) moves the high speed and low speed doors (12, 14) between the open and closed positions. A drive arm (24) interconnects the doors to move the low speed door (14) at approximately one-half the speed of the high speed door (12) driven by the drive mechanism (22). One end (38) of the drive arm (24) is connected pivotally to the door guide (20) of the elevator car (11). Each door (12, 14) has a pin (32, 34) extending from a bracket (26, 28) connected to each respective door for sliding engagement with a pair of slots (42, 44) that extend longitudinally along the drive arm (24). The length of the slots (42,44) are sufficient to permit movement of the doors (12, 14) between the open and closed positions. The weight of the drive arm (24) at a predetermined center of gravity (50) provides a predetermined closing force (F.sub.HC) to the high speed door (12) in the closed position and a reduced closing force (F.sub.HO) to the high speed door in the open position.

摘要： An overlay for a elevator guide rail extends over the joints between segments to provide a seamless engagement surface for the guide rail. The overlay separates the engagement surface from the joints between adjacent segments to minimize vibration and improve the comfort of the ride. In one embodiment, an elevator includes a guide rail having a support formed from multiple segments joined end to end and an overlay encompassing a portion of the support. The overlay defines the engagement surface for the guide shoes of the elevator.

摘要： The handrail drive utilizes one or more pairs of drive chain sprockets and idler sprockets which form a nip over which the drive chain moves. The drive chain and idler sprockets are mounted on rotating drive shafts which in turn are eccentrically mounted in rotatable bushings. The drive rollers will automatically tighten on the handrail as friction increases between the rollers and handrail due to increased resistance to movement of the handrail. The rotatable bushings on each drive sprocket and its associated idler sprocket are connected together to ensure that chain tension equalizes between each drive and idler sprocket so that no drive chain slack will occur.

摘要： The escalator handrail guide rail assembly includes a metal base which can be snap fitted onto a glass escalator or walkway balustrade. A low friction plastic strip is fitted onto the top of the base for contact with the handrail, and a metal reinforcing piece is snap fitted onto the base over the plastic strip to hold the latter in place, and to reinforce the plastic strip. The reinforcing piece is formed from two identical interleaved strips which can be attached to and detached from the base without the use of any tools more specialized than a rubber mallet and without the use of separate fasteners such as screws, bolts, or the like.

摘要： The handrail guide is suitable for use on very thin escalator balustrades, such as are typically made of glass or the like. The handrail-contacting-track surface is formed from a low friction plastic material. The plastic track member is affixed to a mount base which clips onto the balustrade, and the track is reinforced by a recessed steel strip plate fastened directly to the base through the track.

摘要： The handrail guide rail has a base part which is preferably extruded metal, and can be rectilinear or curvilinear. The base telescopes over the top of the escalator balustrade which is a relatively thin glass or metal component of the escalator. Spring clamps are trapped between the balustrade and the guide rail base to clamp the base onto the balustrade.

摘要： An escalator is provided with a curved path of travel from its entry to its exit landings. The path of travel of the escalator steps as seen in plan is a curve having a fixed center and a constant radius from landing to landing. In elevation, each landing portion will be disposed in vertically spaced horizontal planes, and there will be a medial constant slope ascending or descending portion. Interconnecting each landing portion with the constant slope portion will be entry and exit transitional curved portions of varying slope as seen in the elevational view. To enable the steps to traverse the curved path successfully, the effective length of at least one of the step chains is varied at different points along the path of travel of the escalator.

摘要： A termination device for terminating a flexible flat tension member includes a socket and two opposing wedges mounted therein. One of the wedges is preferably pinned within the socket while the other wedge is removable. The invention provides a reliable termination with a safety back-up to retain the tension member even if friction in the device is reduced due to soiling with a friction reducing material.
