In an escalator having a plurality of steps connected to an endless chain and moved along an endless path, a rotation locus of step forward wheels at both end portions is shifted toward end portions of the escalator relative to a rotation locus of the chain. A forward wheel guide track for guiding forward wheels of the steps is arranged, at both end portions of the escalator, so that a straight distance between forward wheels of two adjacent steps, which distance tends to be shortened by the chain following an arc at both end portions, is extended. By such constructions, interference between adjacent steps hardly occurs even if the rotation diameter of the steps at each end portion of the escalator is made small. Therefore, the rotation diameter of the steps can be made smaller than a conventional one and the escalator thickness (depth) can be made small.

Escalator

An object of the present invention is to provide an escalator installation method by which the installation operation can be conducted with the high operation efficiency and an escalator can be stably installed. In an architectural structure having a stairway, the present invention comprises: a first process for forming a lower pit in a lower floor positioned on the lower side of the stairway; a second process for forming an upper pit in an upper floor positioned on the upper side of the stairway; and a third process for accommodating a lower flat portion of an escalator constituted by an integral structure in the lower pit with the part of the stairway positioned between the upper pit and the lower pit being maintained so as not to be drilled, accommodating an upper flat portion in the upper pit, and setting an inclined portion of the escalator above the part of the stairs positioned between the upper pit and the lower pit.

Escalator installation method

Escalator apparatus of the invention is of the type that has a step whose step board can be raised to provide a surface for carrying a wheelchair. In order to realize conveyance of a large size wheelchair or handcart without changing the installation space for the escalator, the escalator apparatus of the invention is structured such that the step boards of a plurality of adjacent steps are movable upwardly and downwardly.

Escalator apparatus and method of operation

A drive unit of a conveyer having a frame structure extending from one place to another place, a step chain mounting thereon a plurality of step treads and arranged inside the frame structure and a step chain sprocket for driving the step chain, which drive unit comprises a reduction gear and a motor for driving and controlling the step chain sprocket through the reduction gear, and is characterized in that the whole upper side of the reduction gear is of an opening covered with a base plate, and that the base plate is formed by unifying a top cover for the opening of the reduction gear and a motor base through reinforcing ribs disposed therebetween so as to be parallel to each other, the motor being mounted on the base plate so as to be horizontally movable in a direction perpendicular to an output shaft of the motor.

Drive unit of conveyor

In a passenger conveyor, in order to reduce installation dimensions and, more particularly, a height of the passenger conveyor, the passenger conveyor is constructed to be driven by a linear motor, with stators and moving members of the linear motor being formed such that surfaces thereof facing each other are located in horizontal planes and generated magnetic flux of the stators is perpendicular to the facing surfaces. The moving members are mounted on the respective treadboards.

Passenger conveyor and treadboard construction for passenger conveyor

A passenger conveyor includes a platform floor having a slanting portion. A length of the slanting portion is not less than a length of each of treadboards of the passenger conveyor, and at least one of the treadboards of an advance side, when passing under the platform floor, is disposed horizontally beneath the slanting portion. With this arrangement, a push cart or the like can be smoothly moved from the treadboard to the platform floor.

Escalator control box

A passenger conveyor, such as an escalator or a moving walkway, in which a device for transmitting a change of direction of the movement of treadboards to a passenger by changing the passenger's sense of touch is provided in the vicinity of a boundary between a horizontal path and an inclined path. With this construction, a level difference between the adjacent treadboards is produced when the treadboard moves into the inclined path, thereby preventing the passenger from accidentally falling down.

Passenger conveyor

A passenger conveyor comprises a moving handrail mounted on a guide rail provided around a balustrade and a handrail driving device for driving the moving handrail to move circulatively. The moving handrail is constituted by a core member and a surface decorative member which is removably attached, i.e. removably engaged, to the core member, and the core member is driven by the handrail driving device. The moving handrail may be constituted by a core member and a surface decorative member which are formed separately and joined together.

An escalator comprises a plurality of treadboards, coupled with each other in the endless form, for conveying people thereon, a driving device for driving the treadboards, which has a driving mechanism, including an electric motor, for transmitting a driving force from the motor to the treadboards and a power converting unit for supplying electric power to the motor. Component devices of the driving device are categorized into two groups in consideration of heat generated in the respective component devices. Component devices, which are categorized into a group of heat generating devices, are installed in a machine room, and component devices, which are categorized into a group of heat sensitive devices, are installed in another machine room. The two machine rooms are arranged in different locations within an escalator frame, which are remote from each other in the direction of the length of the frame.

People mover apparatus

Indicating apparatus for passenger conveyor includes an indicating body arranged near a platform of the conveyor and outside a balustrade panel. The indicating body is located and secured at a position where the upper edge thereof is downwardly apart from a frame which is mounted on the upper edge of the balustrade panel for supporting a moving handrail.

In a balustrade for a passenger conveyor, a main deck is fixedly mounted to an upper end of a vertically upright balustrade panel, and a guide frame is arranged on the main deck for slidingly guiding a handrail. In order to easily carry out an operation of fixedly mounting the main deck to the upper end of the balustrade panel, at least one fixing instrument is provided which has an inverted U-shaped fitting groove on one side and a fixing section on the other side, and the main deck is fixedly mounted to the upper end of the balustrade panel through the fixing instrument.

Balustrade for passenger conveyer

A passenger conveyor has a pair of balustrades on opposite sides of a plurality of steps connected together to circulate endlessly. Each of the balustrades comprises a structural support member mounted on a main body frame in spaced relation in the length direction of the main body frame. The structural support members each are made of a casing of one piece and have a U-shaped support portion supporting a lower end portion of the balustrade, a mounting flange portion projecting horizontally from one side of the U-shaped support portion, being mounted by the main body frame and mounting thereon an outer deck cover, a mounting projection horizontally projecting from the opposite side of the U-shaped support portion and mounting thereon an inner deck cover and skirt guard, and a pair of downward projections which serve to reinforce the U-shaped support portion as well as connection of a handrail guide for holding a handrail.
