Problems solved by technology

Especially when retrofitting modern elevator installations for buildings, such a magnetic strip is also impractical due to the additional installation costs
If redundancy is to be created and thus two separate magnetic strips are required to be installed along the shaft, the cost will increase further

Embodiment Construction

[0041] Basic structure of the system

[0042] Figure 1 first shows the basic structure of the system. At least one unit, collectively referred to here as a speedometer, consisting of two wheels 9 and a detector 11 here in the form of an encoder, as well as the associated frame, is mounted on the car (that is to say moved). An emergency braking electronic device 13, referred to here as a signal processor, is also installed on the car, and it sends out an emergency braking signal in the case of overspeed or unacceptable acceleration or uncontrolled elevator operation, and is also equipped with a The triggering unit, which generates the force required to activate the braking device or safety gear, and which is also collectively referred to as the braking device or the safety gear itself is also mounted on the car. The conventional elevator control, referred to as electronic control in FIG. 1, is installed in the hoistway (that is to say in the hoistway or in the associated drive...

Abstract

The invention relates to an apparatus for application of a magnetic field to a sample, in particular an elongated sample. At least in places, the apparatus has magnetic bodies which are arranged such that they can rotate with respect to one another and have, and leave open, a common access opening for the sample. In particular, this allows the apparatus to be applied to an elongated sample whose ends are not accessible. As a result of the bodies being arranged such that they can rotate with respect to one another, the magnetic fields of the bodies can be adjusted with respect to one another before the apparatus is opened and closed, so as to minimize the magnetic field in the common access opening. In consequence, only small magnetic interaction forces need be overcome during opening and closing.

Description

technical field [0001] The invention relates to a detector according to the preamble of claim 1 for travel values, speed values ​​and / or acceleration values ​​for an elevator cage or elevator car (hereinafter referred to collectively as elevator car). Background technique [0002] Elevators equipped with brakes or safety gear or combined safety gear brakes, which occur at excessively high speeds (so-called overspeed), for example in the event of a malfunction of the controller, failure of the drive or brake, or breakage of the traction rope At high speeds, it is used to stop or brake the elevator car within the allowable limit value by means of the friction body acting on the guide rail. In this context, a braking device is generally understood to be a device which prevents the elevator car from overspeeding in the upward direction by stopping the elevator car or by stopping the counterweight at the end of the run as required by a buffer, This ends the unscheduled operation...
