Abstract:
Pivoting arrangement (J) of an emergency exit hatch (2) of an elevator, said arrangement being for a surrounding frame structure (1), a roof element (E) of an elevator, and an elevator, in which arrangement the emergency exit hatch (2) of the elevator is a planar element, and comprises pivot brackets (3.1, 3.1') on its opposite sides, and the frame structure (1) comprises an aperture, which the aforementioned hatch is arranged to cover, and which aperture comprises pivot apertures (7.2, 7.2') in its opposite sides, for receiving the aforementioned pivot brackets (3.1, 3.1'), and the aforementioned planar hatch element (2) and/or the aforementioned frame structure (1) is/are fabricated from plate material, and the part (7, 7' ) of the frame structure comprising a pivot aperture (7.2, 7.2') and/or the part of the hatch (2) comprising a pivot bracket (3.1, 3.1') is/are of the aforementioned plate material.
Abstract:
Diverting pulley arrangement, more particularly a diverting pulley arrangement of an elevator, which arrangement includes an axle, at least one diverting pulley that rotates while supported on the axle, a faceplate structure, in relation to which and supported by which the diverting pulley is arranged to rotate on the first side of the faceplate structure, which axle is locked so that it does not rotate by the aid of a locking element that moves in relation to the faceplate structure, which locking element is on the second side of the faceplate structure. When it starts to rotate, the end of the axle forces the locking element to displace out of its position and to trip a safety switch.
