Abstract
People movers, such as escalators and moving walkways, for instance, may comprise a support member belt comprised of a plurality of support members guided on rails. The support members may be, for example, steps of an escalator or pallets of a moving walkway. Each support member may be secured to a pair of drag rollers that runs on the rails, and each support member may include a roller spindle that is held rotationally conjointly in or on a body of the support member. Between the roller spindle and the body of the support member, there may be a plug-in connection by way of which the roller spindle is maintained against an undercut under bias of a latching device.
Claims14
A people mover comprising:
- a support member belt comprising a plurality of support members guided on rails;
- and
- at least two drag rollers mounted to at least one of the plurality of support members, wherein the at least two drag rollers travel along the rails,
- wherein each of the at least two drag rollers comprises:
- a roller spindle that is inserted into and coupled rotationally conjointly with a recess of a body of the at least one of the plurality of support members, the roller spindle comprising a ledge having a surface that faces the body of the at least one of the plurality of support members;
- and
- a latching device disposed at an undercut and configured to couple the roller spindle to the body of the at least one of the plurality of support members, the latching device being biased to both retain the roller spindle at the undercut in a resilient latching connection and force the ledge of roller spindle to bear against the body of the at least one of the plurality of support members.
A people mover comprising:
- a support member belt comprising a plurality of support members guided on rails;
- and
- at least two drag rollers mounted to at least one of the plurality of support members, wherein the at least two drag rollers travel along the rails,
- wherein each of the at least two drag rollers comprises:
- a roller spindle that is held rotationally conjointly in or on a body of the at least one of the plurality of support members, wherein a plug-in connection is used to secure the roller spindle to the body of the at least one of the plurality of support members, wherein the plug-in connection comprises a clamping connection, wherein bias from the clamping connection is used to maintain the roller spindle against an undercut.
