used for example for a bowden pull obviously pull rods with articulated connecting points or also a pull chain could be used instead of pull cables however the connecting means is merely to be designed in order to transmit a pulling force to the brake unit 9 it is a pull means fig3 shows a possible construction of the brake unit 9 in the example there is shown an unactuated brake which is connected in known mode and manner by way of a floating mounting with an abutment at one side relative to the elevator car 3 the connecting means 11 or the pull cable 12 in the case of actuation adjusts a movable brake lining by way of a force translation lever 14 and thus firmly clamps the guide rail 7 a braking force by means of which the elevator car 3 is braked or held arises through this clamping force or pressing force f n the brake unit is actuated by the connecting means 11 in force active manner i e the brake unit is in opened or non braking position in the absence of an actuator force f a transmitted by the connecting means 11 fig5 shows another embodiment of the brake unit 9 in this.
