Abstract: A passenger conveyor system (20) includes a handrail assembly (30) having a guidance (40) for guiding a moving handrail (32). The example guidance includes an extrusion and presents a continuous, uninterrupted guiding surface (44) along which the handrail (32) travels. In a disclosed example, a single-piece extrusion (50) extends along an entire length of a balustrade (34). A disclosed example includes a first material forming a body of the guidance (40) and a second material (70) establishing the guiding surface (44).

Abstract: An elevator sheave (20) includes a belt guiding surface (26) having a surface profile along at least a portion of the belt guiding surface. The surface profile preferably is defined by an nth order polynomial equation where n is a number greater than 2. In one example, the reference point (40) is a central point along the width of the belt guiding surface (26). In one example, a central portion (42) of the surface profile preferably is aligned to be generally parallel with the central axis (34) of the sheave body. Some examples have curvilinear side portions (44, 46) between the central portion (42) and the edges (28, 30) of the sheave. Other examples also include second side portions (48, 50) that have linear profiles.

Abstract: An example drive train assembly for a power conversion system includes a first sprocket which defines an axis of rotation, at least two secondary sprockets adjacent to the first sprocket and at least one belt. The axis of rotation lies outside of an area defined by the belt. The belt is operable to transfer mechanical power between the first sprocket and the two secondary sprockets in response to a rotation of the first sprocket about the axis of rotation. The belt defines a first side having one of a first plurality of notches and a first plurality of teeth and an opposing second side having one of a second plurality of notches and a second plurality of teeth. The first sprocket defines the other of the first plurality of notches and the first plurality of teeth and the secondary sprockets define the other of the second plurality of notches and the second plurality of teeth.

Abstract: A passenger conveyor system (20) includes a drive module (40) that engages a step chain (30) to move steps (22) as desired. A non-metallic drive belt (50) includes a unique configuration of teeth (60) that engage teeth (70, 80) of the step chain (30). In one example, the drive belt teeth (60) include a projection (64) that provides the initial engagement point with the step chain teeth (70, 80). In another example, the teeth (60) include a generally concave step chain link teeth engaging surface (62). The inventive arrangement provides smoother, quieter system operation and minimizes the separating forces that otherwise tend to occur between the belt and the step chain links.

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.
