A chute apparatus for conveying objects by gravity from at least one higher floor to at least one lower floor of internally a building includes one or more sets of discrete sections having passages which form an elongated conduit which may pass through one or more floors inside the building. The passage of one section of each set section decreases in transverse cross section in a given longitudinal direction and a passage of one of the other sections increases in transverse cross-section by a substantially corresponding amount. Two sections of each set couple telescopingly to permit their longitudinal span to be selected and/or adjusted in the field.
