The invention relates to a method for guiding a drive chain containing links, guide rolls and connecting elements in the area of a reversing device, which is formed by a chain wheel, of a pedestrian conveyor system, particularly of an escalator or a moving sidewalk, whereby the guide rolls are supported, at least on the chain wheel side, on a guide profile. In drive chains of this type, which have connecting elements in the coupling areas of the links and in which a guide roll mounted between the links is provided in the remaining free space, the drive chain is led into the chain wheel such that when viewed in a moving direction the front connecting element of each link element is firstly placed in an associated accommodating area and the guide roll is subsequently placed in a corresponding calotte, and the rear connecting element is firstly led into the associated accommodating area when the guide roll is supported in the calotte in an elastically damped manner.

The invention relates to a device for connecting at least one drive belt or the sections thereof to a moving sidewalk pallet. Said invention is characterised in that the drive belt is provided with an element protruding towards the pallet which comprises a receiving area at determined intervals and for each pallet. Said receiving area and protruding element can be connected by form-fitting connection. In order to embody the form-fitting connection between terminal areas of a segmented drive belt or between the terminal areas of sections thereof, said areas are provided with guiding areas.

The invention relates to a method for regulating the brake(s) of an escalator or moving walkway, independently of the load. According to the invention, actual values (I) are supplied to at least one regulator which contains at least one theoretical value (S), the regulator intermittently performs a comparison between the theoretical and actual values and controls at least one brake magnet using these values. The brake magnet or magnets in turn regulate(s) the brake(s) in such a way, that a predeterminable linear braking deceleration can be achieved, whereby theoretical values (S), in particular, in the form of several temporary deceleration values are stored in the regulator in theoretical value fields or theoretical value zones.

The invention relates to a method for disconnecting passenger transport systems, especially escalators and moving walkways. To this end, functional units monitor for malfunctions by using switching elements and are combined to form a security chain using signals. The signals of the functional unit are fed with those from the drive monitoring system to at least one pilot unit before the disconnecting signal is fed to the respective disconnecting contact according to the malfunction of the respective functional unit and/or of the drive monitoring system.

The invention relates to a method for load-independently braking the step or pallet belt of an escalator or a moving walkway. According to said method, the activation of at least one safety element triggers at least one frequency converter in such a way as to activate a time-dependent braking ramp, said frequency converter interacting with the drive motor. The braking ramp then slows down the step or pallet belt to 0 m/s with essentially constant deceleration.

The invention relates to a comb profile for comb supports of escalators and moving walks which consists of a plurality of segments that can be linked with the comb support. Individual or several segments can be releasably interlinked outside the comb support. Segments that are juxtaposed with their front faces are functionally joined by tongue and groove joints.
