A parapet is erected on the frame 1, 5 is a floor plate fixed to the upper and lower floor entrances, and 6 is a user in a wheelchair 61. In addition, the special step 31 includes an elevating step board 32.
A movable part 34 is provided which has a movable step plate 33 pivotally connected to the lower end of the movable part 34, and although not shown, the elevating step plate 32 is moved via a cross link or the like by forward and reverse rotation of a drive source such as an electric motor. As it is raised and lowered, the movable tread 33 rotates to the lower floor and upper floor via the link, and when the tread 32 is raised, the movable tread 33 extends to the lower floor, and when the tread 32 is lowered, it extends onto the movable tread 33. They are arranged so that they overlap closely. The following steps are taken to transport the wheelchair user 6 using the conventional escalator configured as described above. In the case of upward operation of the escalator, when the wheelchair user 6 comes to the floor plate 5 of the entrance/exit on the lower floor, the special step 31 moves the normal continuous escalator to the horizontal part A of the lower floor immediately before the floor plate 5. Stop in position. Next, the m drive source of the special step 31 is rotated in the forward direction, the elevating step board 32 is raised, the movable step board 33 is extended toward the lower floor, and the drive source is stopped. In this state, the wheelchair user 6 and the wheelchair 61
The user gets on the elevating footboard 32 and the movable footboard 33 from above the floorboard 5. At this time, after the wheelchair 61 gets in, the wheelchair 61
In order to prevent it from falling to the lower floor side,
A car stop 39 as described in the 8281 publication can be pivoted to the movable footboard 35, and the car stop 39 can be raised above the free end of the movable footboard 33 located on the lower floor side on the tip side of the floorboard 5. Conceivable. After the wheelchair user 6 gets on the special steps 31 as described above, the escalator is operated upward and the special steps 31 are reached through the constant slope section BJe.
The escalator is stopped when the normal steps 3 adjacent above reach the horizontal part C of the upper floor. Next, the wheelchair user 6 and the wheelchair 61 descend from the special steps 31 to the horizontal normal steps 3 and onto the passenger entrance floorboard 5 on the upper floor. After the wheelchair 61 gets off the special step 31, the drive source is reversed, and the movable step board 33 is moved to the elevating step board 32.
The elevating step board 32 is lowered and returned to its original position while being stacked on top, and the special step 31 can be used in the same way as the normal step 3. In addition, when the car stopper 39 is used, it is returned to the movable step plate 33 and horizontally in a timely manner. after that,
Let the escalator operate normally. In addition, in the case of descending operation of the escalator, the wheelchair user 6 gets on the special stairs 31 from the entrance floor plate 5 on the upper floor via the horizontal regular steps 3, gets off at the lower floor, and the boarding and alighting position is changed to the ascending operation. The operation is almost the opposite of that during upward operation, such as in the opposite direction. However, when the wheel stopper 39 is used, it is necessary to raise the wheel stopper 39 before the wheelchair user 6 gets on the vehicle, and return it before the wheelchair user 6 gets off. Become.

輸送能力を向上させることを目的としている。In conventional escalators, such as the special steps configured as described above, a bollard that can be raised and folded is pivotally attached to the movable part, and this bollard is raised from the lower end of the movable part during wheelchair operation. It is necessary to change the timing of raising and lowering the bollard, that is, raising and returning the wheel stopper, depending on whether the wheelchair is being driven up or down and when the wheelchair is in use. In other words, if the bollard is connected to the movable part by a link and these are configured to work together, the timing of the bollard's operation cannot be automatically controlled, and when the user of the wheelchair gets on or off the special steps. , it is necessary to climb over raised bollards, making smooth and safe operation impossible, requiring manual operation by an attendant, prolonging the preparation time for wheelchair operation, and reducing the transportation capacity of the escalator during normal operation. There was a problem in that it lowered the This invention was made to solve the above-mentioned problems. It has a simple structure, is highly reliable, and can automatically control the timing of raising and lowering the bollard, making it easier for wheelchair users to drive. The aim is to shorten preparation time and improve transportation capacity during normal operation.

By supplying power to the vehicle and driving them in reverse, the elevating footboard 32, the movable footboard 33, and the wheel stopper 39 are moved from the wheelchair transporting state to the third stage (not shown in FIG. 1).
Return to the normal operating state shown in the figure and operate the escalator normally. When transporting from the lower floor to the upper floor, the escalator is stopped by placing the holding step 31 at a predetermined position close to the horizontal part of the upper floor, and the escalator is rotated forward by the normal rotation of the electric motors 321, 331 and 391. Rise, movable tread 3
3 is reversed and the wheelchair is conveyed in a state where the wheel stopper 39 is upright. 1: The wheelchair is put on the special steps 31 in this state, and at this time, the wheel chair is prevented from falling due to overrun by the wheel stopper 39. Next, the escalator is operated downward, and the special step 31 is placed in a predetermined position on the horizontal part of the lower floor near the lower floor entrance and exit, and the escalator is stopped. Then, only the electric rJjJ machine 391 for standing up is driven in reverse, and the car stopper 39 is moved. The wheelchair is returned to a horizontal position with the movable tread 33, and in this state, the wheelchair is lowered from the special step 31 to the entrance on the lower floor. After that, the elevating/lowering electric motor 321 and the reversing electric motor 391 are reversely driven to return the elevating/lowering step board 32 and the movable step board 33 to the normal operating state. The operations of this embodiment other than those described above are the same as those shown in FIG. As described above, in this embodiment, the elevating step board 32, the movable step board 33, and the car stop 39 can be operated independently by the elevating motor 321, the reversing motor 331, and the elevating motor 44391, which are provided separately. It has a simpler structure compared to those that link elevating and movable treads with various links such as dog and small irregularly shaped links.
Ensure reliability. In addition, each of the above Ti motives 321, 3
The control of 31°391 can be easily automated using a control panel, and the raising and returning of IjL stop 39 (even if the 5th ring is different for ascending and descending escalator operation, this can be controlled electrically with a single button operation). This problem can be solved, and the operation of the bollard 39 that is farthest from the step body 311 can be easily controlled when necessary, thereby shortening the preparation period for wheelchair operation and improving the transportation capacity of the escalator during normal operation. Furthermore, in this embodiment, since the reversing electric motor 331 and the standing electric motor 391 are provided on the same side edge of the movable footboard 33, it is possible to reduce the space in which the wheelchair is placed. As shown in FIG.
By inverting only the movable step board 33 with the reversing electric motor 81331 and the standing electric motor 391 stored in the space 319 between the step body 311 and the elevating step board 32, you can insert your hand from the space 319 and remove the step body. 311, and the equipment located on the top surface of the movable tread 33 when it is inverted. Therefore, the structure in which the elevating tread and the movable tread are linked. Unlike conventional products, which require disassembling and reassembling component parts, repair and inspection work in the event of a breakdown can be done quickly and easily. Note that this embodiment can be used in combination with a floor plate that also serves as a wheelchair boarding platform that can be raised and lowered, which is provided at the lower floor entrance and exit, which the inventor has proposed at the same time. Until the wheelchair gets on the special steps 31 on the floor side, the elevator tread 32 and the movable tread 33 should be raised low and the movable tread should be kept in an inverted state to make it easier for the wheelchair to get on. The footboard 33 can be raised to a required height and the escalator can be controlled for wheelchair operation. In this case, the lower floor entrance floor plate may be of a fixed type. Furthermore, in this embodiment, one of the left and right electric motors 321 for lifting and lowering may be omitted, and one screw shaft 322 may be interlocked with the other using a gear or the like, and each electric motor 3
