Abstract: An escalator step includes a tread having a body section on which a plurality of convex sections are arranged in parallel, a riser connected to a rear end portion of the tread and having thereon a plurality of convex sections and a plurality of concave sections formed between the adjacent convex sections, and a shock absorbing cleat provided on a corner at which the riser and tread are connected to each other. The shock absorbing cleat includes a plurality of long convex sections which are arranged in parallel and a plurality of short convex sections which are arranged in parallel between the adjacent long convex sections. The shock absorbing cleat is formed of a polymeric material having a Young's modulus of 1000 MPa or less.

Abstract: An escalator step includes: a tread that includes a body section wherein a plurality of convex sections, which are parallel in a travelling direction, are arranged in a width direction; a riser that is coupled at a rear end portion of the body section of the tread and on which a plurality of convex sections are arranged in a width direction, with troughs being formed between adjacent convex sections; and a shock absorbing cleat located in a notch formed in a corner portion where the riser and the tread are coupled together. On the shock absorbing cleat, a plurality of convex sections, arranged in a width direction and parallel to the travelling direction, rear end surfaces are flush with troughs of the riser, each of the convex sections of the shock absorbing cleat is shifted a half pitch from each of the convex sections of the riser.

Abstract: A double-decker elevator includes a winch, an upper car, a lower car, a car support frame supporting the upper and lower car, a car space adjusting device capable of adjusting the space between the upper and lower car, and an emergency operation controller. When the car space adjusting device is unable to operate normally, the emergency operation controller operates the winch to move the car support frame such that the upper and lower car are located sequentially at positions corresponding to adjacent floors, respectively.

Abstract: An elevator including a cage configured to ascend and descend in an elevator shaft, and at least one railing member disposed along at top edge of the cage and configured to be adjustable in height so that during performance of maintenance by a maintenance person, the railing is adjusted to be in an upright position, and is otherwise maintained in a position lower than a highest protruding object existing on the top of the cage.

Abstract: An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave 1 and a driving mechanism 2 is positioned between an inner wall 3a of the elevator path 3 and a space occupied by an elevator car 4 rising and falling in the elevator path 3. One end of a suspension rope 7 is fixed to the elevator car 4 in a position below a ceiling 4c of the elevator car 4. With the arrangement, the car 4 can move close to the ceiling 4c of the elevator car 4 effectively. Further, it is possible to reduce respective heights of the elevator path 3 and a building equipped with the elevator apparatus.

Abstract: In an elevator, a driving unit is installed at the top of an elevator shaft above a counterweight. Traction sheaves engage with ropes and are rotated by the driving device. These traction sheaves are positioned close to wall surfaces of the elevator shaft, that are adjacent to its wall surface facing the counterweight. The traction sheaves are also positioned outside the horizontally projected plane of a car.

Abstract: A double-deck elevator includes a winch (6), an upper car (2), a lower car (3), a car support frame 1 supporting the upper and the lower car (2, 3), a car space adjusting device (4) capable of adjusting the space between the upper and the lower car (2, 3), and an emergency operation controller (12). When the car space adjusting device (4) is unable to operate normally, the emergency operation controller (12) operates the winch (6) to move the car support frame (1) such that the upper and the lower car (2, 3) are located sequentially at positions corresponding to adjacent floors, respectively.
