Abstract: The handrail drive has opposed rollers which are movable toward and away from each other due to their eccentric mountings. Two sets of such opposed rollers are used to drive the handrail. Each set of rollers is equipped with its own drive chain to increase the efficiency of each set of drive rollers with ultra high loads. The drive is particularly suited for moving high load escalator and moving walkway handrails.

Abstract: The handrail drive utilizes one or more pairs of drive rollers which form a nip through which the handrail moves. The drive rollers are mounted on rotating drive shafts which in turn are eccentrically mounted in rotatable bearings. 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 bearings are connected together to ensure that each roller tightens equally on each side of the handrail so that the handrail is not bent through an S curve as it passes through the drive roller nip.

Abstract: Movable vanes mounted on the exterior of an elevator car door engage rollers on the interior of the hallway door as the car door commences to open. Subsequent opening and closing movement of the car and the hallway doors occurs simultaneously and at the same speed so that there is no mismatched motion between the doors.

Abstract: 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.

Abstract: A pitless elevator system removes a car buffer and machine, and other components where so equipped from under the elevator car such that the elevator car can be operated to a clearance between it and a floor of a hoistway of about three inches. The machine may be mounted on board the car or may be located elsewhere and the car buffer located in normal side clearance space. The system further provides a retractable toe guard to allow the car to bottom at the indicated distance from the floor. The system facilitates retrofit applications of elevators without the prior art drawback of digging a pit.

Abstract: 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.

Abstract translation: 用于电梯轿厢（11）的两门组件（10）包括在打开和关闭位置之间移动以关闭电梯轿厢的入口（16）的高速门（12）和低速门（14）。 门（12,14）可滑动地保持在沿着轿厢入口的顶部设置的集管（18）和沿着轿厢入口（16）的底部设置的门导向件（20）之间。 驱动机构（22）在打开位置和关闭位置之间移动高速和低速门（12,14）。 驱动臂（24）将门相互连接，以使驱动机构（22）驱动的高速门（12）的大约一半的速度移动低速门（14）。 驱动臂（24）的一端（38）枢转地连接到电梯轿厢（11）的门导向件（20）。 每个门（12,14）具有从连接到每个相应门的支架（26,28）延伸的销（32,34），用于与沿驱动臂纵向延伸的一对槽（42,44）滑动接合 24）。 槽（42,44）的长度足以允许门（12,14）在打开位置和关闭位置之间移动。 驱动臂（24）在预定重心（50）处的重量在关闭位置向高速门（12）提供预定的关闭力（FHC），并且将关闭力（FHO）降低到高速 门处于敞开的位置。

Abstract: A simplified elevator car door lock assembly locks an elevator car door if the car is outside a landing zone and there is an attempt to open those doors. The car doors are connected to the hoistway doors by a pair of vanes mounted on the car door and a pair of rollers mounted on the hoistway door. A third vane is attached to the car door and follows a cam path on the car door to lock the car doors if the car is not in a landing zone. Conversely, the third vane senses if the car is in a landing zone and does not lock the car door if it is moved.

Abstract: 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.

Abstract: 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.

Abstract: 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.
