Abstract:
The present invention relates to a door frame assembly (22) for an elevator assembly which comprises a head jamb member (24), a sill member (26), a plurality of side members (28) which extend between the head jamb member (24) and the sill member (26), and at least one adjuster (30) which is operative to selectively adjust a position of the sill member (26) relative to a landing surface (18). A method of mounting a door frame assembly (22) that includes securing a portion of the door frame assembly (22) to a landing surface (18) and subsequently adjusting a position of the sill member (26) relative to the landing surface (18) all from the landing surface side of an opening to a hoistway is disclosed.
Abstract:
An elevator door moving arrangement includes a door mover (40) and an interlock device (42) supported near a lower edge (44) of cabin doors (26). The strategic position of the door mover (40) and the interlock device (42) minimizes the distance between the sill member (34, 78) and the operative components for moving the doors. In one example, the entire door mover assembly and the interlock are located beneath a sill member (34), which is beneath the bottom edge of the doors (26).
Abstract:
The present invention relates to a pulse free escalator system having two spaced apart pulse free turnaround sections and at least one pulse-free transition zone and to a method of designing the turnaround sections and the at least one transition zone. The escalator system has a pair of guide tracks and a pair of linkage assemblies, each comprising a plurality of links joined together. Each linkage assembly has a plurality of rollers for supporting the linkage assembly which travel in a respective one of the guide tracks. Each guide track has two spaced apart turnaround portions with each turnaround portion defining a travel path for each roller having a linear entry section, a linear exit section, and a pulse-free section intermediate said two sections.
