Elevators and equipment used to create safe spaces

Abstract

An elevator includes at least an elevator car arranged to move reciprocally in an elevator hoistway and fitted on guide rails, a plurality of landing doors having landing door locks openable e.g. with a service key, and a safety arrangement arranged to form a safe space, preferably a working space, in the elevator hoistway below the elevator car, access to which safe space is enabled via at least one landing door in the proximity of the base of the elevator hoistway, and / or a safe space, preferably a working space, above the elevator car, to which access is enabled via at least one landing door leading to the roof of the elevator car, and in which elevator the aforementioned safe space has a minimum height. The formation of each safe space is arranged to be implemented as a consequence of the opening occurring, e.g. with a service key, from a floor level of a landing door enabling access into the elevator hoistway.

Description

technical field [0001] The object of the invention is an elevator comprising a plurality of landing doors. The invention also relates to the formation of one or more safe spaces. Background technique [0002] Usually, in an elevator, the elevator car is arranged to run up and down an elevator shaft, which is usually a closed space into which persons other than maintenance employees cannot enter. In a maintenance situation, it must be possible for a maintenance employee to enter the part of the elevator which is located in the elevator shaft, which part may be located at the base of the elevator shaft, at the top part of the elevator shaft or somewhere in between. In the case of maintenance, the elevator car has to be driven into a suitable position, depending on where in the elevator shaft the maintenance process has to be carried out. For example, if the maintenance process must be in the base of the elevator shaft, the car must be driven upwards sufficiently so that ther...

Problems solved by technology

[0006] Another problem is that the monitoring solutions used today for the bottom safe space and the top safe space cannot detect which floor level doors have been opened for maintenance services

In this case, it is not clear whether the maintenance worker doing the work is about to get on the base of the elevator shaft or on the roof of the elevator car

Thus, current monitoring solutions according to prior art are complex and unreliable
