An elevator system includes a car which can move in an elevator shaft and has a car roof which has a walkable region. A safety element is arranged in the region of a roof edge of the car roof for reducing the gap between the elevator shaft wall and the car in order to protect people from falling into the elevator shaft. The safety element has a toe board section for creating a toe protection and for laterally bordering the walkable region, wherein the toe board section is arranged such that it is inwardly offset in relation to an outer edge of the safety element and in relation to the roof edge by a safety distance.

A shaft access enabling device of an elevator system has a shaft access control unit and at least one access monitoring unit, wherein the shaft access control unit controls an operating state of the at least one access monitoring unit and the access monitoring unit monitors at least one shaft access. The shaft access control unit has at least two different operating modes for controlling the operating state of the at least one access monitoring unit and inspects access authorization before changing between the at least two operating modes thereof.

In order to achieve simple maintenance and/or installation of an elevator system, a marking device has at least one light emitting unit for generating at least one mark on a component of the system.

Marking device in elevator system

A circuit () for resetting a component () within an elevator safety chain (). The reset circuit () comprises a first reset switch (), a second reset switch () and a door contact (). This first reset switch is mountable within an elevator shaft () and the second reset switch () is mountable outside the elevator. Preferably, the second reset switch () is hidden from members of the general public but is accessible to an elevator technician. The door contact () is mountable alongside the landing door (). The first reset switch (), the second reset switch () and the door contact () are arranged in series so that all must be closed to reset the component () whereby, upon activation, the first reset switch () remains closed for a first predetermined time period (&#x394;t) after which it returns to its open state.

A guide device for an elevator car has a guide shoe that is displaceable by a linear guide that is arranged on the elevator car. Should the elevator car in an extreme situation travel beyond the uppermost floor, the guide shoe is arrested by a projecting console, and the elevator car travels past the console. The linear guide permits the guide shoe to execute a movement relative to the elevator car. Thus, the elevator car, or parts thereof, utilizes the hoistway headroom that is provided for the drive unit or other hoistway equipment. The counterweight can be provided with the displaceable guide shoe for utilizing the hoistway pit in a similar manner.
