Abstract
A plate conveyor or moving walk, especially for transporting individuals, comprising plates or pallets arranged in succession in the direction of travel of the moving walk. These plates are connected with two essentially mutually parallely extending, endless drive chains. Traveling rolls enable the plate conveyor to revolve upon guide rails in one or a number of horizontal and/or inclined planes or portions. The drive chains are arranged along sides of the plates extending parallel to the direction of travel of the plate conveyor. Each chain link is connected by at least one attachment element with one of the plates.

A plate conveyor belt, especially for transporting individuals, comprising:
- a plurality of plates arranged in succession in a predetermined direction of travel of the plate conveyor belt;
- a pair of endless, substantially mutually parallel drive chains for driving said plates;
- said plates being arranged between said drive chains;
- each of said drive chains having chain links;
- guide means for guiding said plates;
- travelling rolls for revolvingly guiding said plates at said guide means in at least one or a number of predetermined planes;
- each of said plates having opposed sides extending substantially parallel to the direction of travel of the plate conveyor belt;
- each drive chain being arranged laterally of and along one of the parallel sides of the respective plates;
- at least one attachment element for connecting each chain link with an associated one of the plates;
- each plate having a prolongation at each said side extending essentially parallel to the direction of travel of the plate conveyor belt;
- each said prolongation extending over its related chain link;
- each said prolongation providing a support portion by means of which the related plate bears at said chain link;
- each support portion having a side confronting the related chain link;
- at least one projection provided at an end of said side of each support portion confronting said related chain link;
- said at least one projection together with the side of the plate forming a guide;
- the chain links of each drive chain comprising wider chain links and narrower chain links, each having pairs of brackets;
- said wider chain links being received in said guide;
- each support portion being further provided with at least one further projection approximately at the central region of a further side thereof confronting the chain link and which further projection extends transversely with respect to the direction of travel of the plate conveyor belt;
- and
- said further projection constituting a guide for an inner surface of the brackets of a narrow chain link.
