Embodiment Construction

[0012] FIG. 1 shows an elevator car 1 running in an elevator shaft 1.1, said elevator car 1 being connected to a counterweight by means of a load-bearing cable running around a drive pulley. The drive wheels, carrying cables and counterweights are not shown in the figure. The elevator car 1 is closed by the car door 1.2. The guide rails 1.3 guide the elevator car 1 on its path. To monitor the elevator car 1 or the counterweight, for example, an overspeed governor 5 operating according to the pendulum principle is provided, wherein the movement of the elevator car 1 or the counterweight is transmitted to the overspeed governor by means of a governor cable 6 5. For example, speed governors operating according to the principle of centrifugal force or inertial force can also be used for monitoring the speed. The overspeed governor cable extends over the entire shaft height and is diverted at the lower end of the shaft with a reversing pulley 7, tensioned with a weight 7.1 and p...

Abstract

A mechanism for engaging a safety gear for an elevator car or counterweight of an elevator in which the elevator includes an overspeed governor provided supervising the speed of the elevator car based on the swing lever principle, whereby the movement of the elevator car will be transferred by means of a governor rope to the overspeed governor. The governor rope extends itself over the entire shaft height and will be returned at the lower shaft end by means of a deflection sheave and stretched by means of counterweight as well as guided at the upper shaft end over a pulley of the overspeed governor. The ends of the governor rope are fastened on a release mechanics arranged on the elevator car and such release mechanics operates in an emergency a safety gear arranged on the elevator car. With the overspeed of the elevator car a rope brake is released upwards.

Description

technical field [0001] The invention relates to a device for actuating a safety brake of an elevator car or a counterweight, consisting of a speed governor monitoring the speed of the elevator car connected to the counterweight by a load-bearing cable, wherein the speed governor cable The movement of the elevator car or the counterweight is transmitted to the overspeed governor, which initiates the braking of the elevator installation in the event of an overspeed. Background technique [0002] A speed governor is known from DE 36 15 270 C2, which monitors the running speed of the elevator car. The elevator car drives a cable pulley with an integral locking ring gear via a wire cable. A cam causes a swing lever having a swing lever boss to swing. A control rod is pivotally arranged on the swing rod, and a coercive device is used to keep the control rod and the swing rod in a relatively static state. The upper end of the control rod is a control bow, and the lower end is fi...
