An elevator roller guide assembly that provides enhanced ride comfort. The assembly includes a chassis, a stop plate mounted to the chassis, a face wheel enclosure that at least partially encloses the face wheel and is connected to a plurality of leaf springs, and a pair of side wheel enclosures connected to the face wheel enclosure by the plurality of leaf springs. The side wheel enclosures each support a side wheel in a fixed relation to the other side wheel. The side wheel enclosures are operably connected to the stop plate by a pair of vertical plates. A multi-axis damper extends from the stop plate to engage the face wheel enclosure and dampen oscillation of the wheel enclosures during operation. A set of delta diameter wheels across all four guides reduces coincident flat spots to improve ride quality. Also, a wheel force gauge is integrated with the face wheel enclosure.

An apparatus for displacing an elevator car from its pathway includes a rotational vehicle configured to rotate around an axis of rotation and at least one guide rail section mounted with the rotational vehicle along, which at least one guide rail section the at least one elevator car is arranged to travel. The at least one guide rail section is mounted substantially parallel to the axis of rotation of the rotational vehicle. The rotational vehicle is configured to rotate 90 degrees. An elevator system is also disclosed.

A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft. The elastomer body is configured to form an elastically spring-loaded universal joint for the attachment of the shaft to provide a universal degree of freedom of an angular movement of the shaft and the roller wheel in relation to the base member.

A roller guide for guiding a car of an elevator system along a guide rail may include a roller carrier that can be attached to the car and several rollers disposed on the roller carrier. The roller may be configured to roll by their respective running surface on a rolling surface of the guide rail. The rollers may each be mounted movably in the roller carrier with a direction component perpendicular to the rolling surface of the guide rail. The rollers may be mounted in operative connection with one another at least in part by way of hydraulic fluid such that a movement of one of the rollers perpendicular to the rolling surface of the guide rail causes a directionally-opposite movement of at least a second of the rollers. The present disclosure also concerns a car and an elevator system that employ such roller guides.

A guide assembly (60) for guiding movement of an elevator car (30) is provided including a first (66) and second (68) guide support coupled to the elevator car (30). The first guide support (66) and the second guide support (68) are separated from one another by a gap (G) wider than an adjacent primary portion (42) of a propulsion system (40) of the elevator car (30). A pair of first guides (70) is mounted to the first (66) and second (68) guide support, respectively. The first guides (70) are substantially parallel and are configured to guide movement of the elevator car (30) in a first direction to maintain a clearance between the primary (42) and secondary (44) portions of the propulsion system (40) of the elevator car (30). A second guide (72) is mounted to one of the first (66) and second (68) guide support. The second guide (72) is oriented substantially perpendicular to the first guides (70). The second guide (72) is configured to guide movement of the elevator car (30) in a second direction.

A universal adapter assembly for connecting a roller guide to a frame of an elevator car where an existing hole pattern in the frame of the elevator car is different from an existing hole pattern of the roller guide. The assembly includes an upper member having a hole pattern complementary to the hole pattern of the roller guide permitting the roller guide to be readily connected to the upper member. The assembly includes at least one low member connected to and disposed below the upper member. The upper and lower members each include at least one enlarged opening to permit relative adjustment of the members to compensate for the differing hole patterns of the roller guide and the frame of the elevator car. Preferably, the assembly is configured to be light weight, easy to install and capable of providing additional vibration damping.

An elevator guide having a base attached to an elevator component, a guide riding along a portion of a rail and a spring biasing the guide in contact with the rail. The guide includes one or more of the following: (i) a guide support member operably associated with the guide for movably supporting the guide so that the guide can move toward and away from a corresponding surface of the rail member wherein the guide support member has a plurality of spring engagement sections configured to vary a system effective spring rate; (ii) a roller including a non-metallic rim molded about a bearing; (iii) two independently adjustable stops and, (iv) an opening adjustment member mounted about a notch in the base to vary the distance between the base and the rail. The opening adjustment member has a width and/or depth greater than a width and/or depth of the notch.

A roller guide according to the present invention includes a frame mount surface portion and a roller mount surface portion to be mounted to a car, which are formed by plastically deforming a single steel plate. Thus, the number of components is reduced to significantly shorten assembly time. In addition, processing costs are also significantly lowered.

A roller apparatus is provided. The roller apparatus may include a bearing wheel configured to rotatably couple the roller apparatus to a roller shaft, and a resilient member radially disposed about the bearing wheel and configured to contact a guiderail at different magnitudes of loads. The resilient member may include a first section of a first diameter and a second section of a second diameter. The first section may be caused to deflect in response to loads within a first load range, while the second section may be caused to deflect in response to loads within a second load range. The resilient member may exhibit a stepwise increase in stiffness with a gradual increase in load.
