Abstract
An elevator installation with hoistway doors has door panels that can be laterally displaced beyond the width of the hoistway, and/or they can be at least partially displaced into the hoistway wall resulting in an elevator installation with improved utilization of building space, which also requires less effort to install. The door frame of the hoistway door assembly is transformed into a flat, wide hoistway wall module with integral hoistway doors such that building space hitherto required in the hoistway by the hoistway wall is reduced. The hoistway wall module is either inserted between the landing floors, or else several such hoistway wall modules are fitted together vertically and form a largely freestanding modular hoistway wall which forms between the elevator installation and the building an interface which is either self-supporting or supported individually on each floor.
