Embodiment Construction

[0056]An unintentional motion regulator 10 for limiting the motion of a moving object according to the invention comprises a pulley 1 and a part 2 connected to the pulley 1 by a coupling device 5 for connecting the part 2 to the pulley 1 via the coupling device 5 Spin together. The unintentional motion regulator also comprises means 3 which can be temporarily switched into a state of limiting the movement of the part 2 for limiting the rotation of the pulley 1 via the part 2 . In this way, the co-rotation of the part 2 with the pulley 1 can be weakened, preferably completely prevented. From restricting the rotation of the part 2 it follows that if the pulley 1 rotates when the movement of the part 2 is restricted then a relative motion is created between the part 2 and the pulley 1 . The part 2 is arranged to stop the rotation of the pulley 1 only after the part 2 and the pulley 1 have moved relative to each other by a certain predetermined amount (A, B). In this way, a stru...

Abstract

Unintended movement governor for limiting the movement of a moving object, which unintended movement governor comprises a pulley (1), a part (2), coupling means (5), with which the part (2) is connected to the pulley (1), for rotating the part (2) via the coupling means along with the pulley (1), and means (3) that can be switched into a state limiting the movement of the part (2). When the means (3) are in the state limiting the movement of the part (2) they are arranged to impair the rotation of the part (2) along with the pulley (1) such that relative movement is caused between the part (2) and the pulley (1) if the pulley (1) rotates, and that when the part (2) is in the limited state in terms of its movement it is arranged to stop the rotation of the pulley (1) or at least essentially decelerate the rotation after the part (2) and the pulley (1) have moved a predetermined amount (A, B) with respect to each other. The elevator according to the invention comprises an unintended movement governor as defined in the preceding.

Description

technical field [0001] The object of the invention is a motion regulator, more particularly a motion regulator for a passenger transport such as an elevator, and an elevator. Background technique [0002] Usually, elevators are provided with a safety device, which can be triggered by activation of an overspeed governor. The traditional solution is that when the speed of the elevator increases to a limit value pre-set for the overspeed governor, the overspeed governor activates the safety device via the same rope through which the overspeed governor monitors the speed of the elevator. In addition to the clamping of the elevator to the guide rails in an overspeed situation, there are also situations in which the safety device should be arranged to work even if the speed of the elevator does not exceed the permitted speed. These cases are, inter alia, the testing of safety devices related to the inspection of the elevator, or if the elevator moves uncontrolled (unintentional m...
