It has the function of operating A).

(23) is a switch disposed at the upper and lower ends of the inside of the handrail (2).As shown in Figure 6, this switch (23) switches the escalator from normal operation to wheelchair operation. It consists of a changeover switch (23a) and a wheelchair operation start switch (23b) that restarts the wheelchair steps (11) temporarily stopped at the entrance.

Next, the operation will be explained, and for convenience of explanation, the case of upward operation will be explained.

First, when the wheelchair user (15) who has come to the entrance floor (1e), which is the boarding entrance, operates the wheelchair operation selector switch (23a) of the switch (23), the actuator ( 22) comes into contact with the boarding day switch (18) to operate it, the escalator decelerates at a specific position, and the motor (174) of the loading device (17) is driven. When this motor (174) is driven, the binion (175) rotates and the rack shaft (171)
) is raised, and the rack (173) is raised to a predetermined position.

Next, the wheelchair step group (11) moves horizontally onto the entrance/exit floor (le), and when the forward rotation pinion (162) of the drive force transmission mechanism (16) sequentially meshes with the rack (173), the drive force is transmitted. The transmission mechanism (16) operates to transform the first and second wheelchair steps (12) and (13) from the normal configuration to the wheelchair configuration, forming part of the wheelchair configuration. To explain this transformation operation in detail using the second wheelchair step (13) as an example, the normal rotation pinion (162) that moves horizontally in the direction A shown in Figure 10 meshes with the rack (173) and moves in the direction B shown in the figure. The reverse rotation pinion (165) rotates and meshes with the forward rotation pinion (162), and the intermediate gear (165) rotates counterclockwise, and the intermediate gear (165) meshes with the rack (133).
168) - (168A) rotates counterclockwise, and the pair of forks (132) protrude and move in the direction of the arrow shown in the figure. Then, the pair of forks (132) pass through the through hole of the cleat riser (131) and through the hole (143) of the movable tread (141), thereby connecting the second wheelchair step (13) and the movable tread (141). The wheelchair step group (11) then stops at the entrance/exit floor (1e). still,
The reversing pinion (165) rotates as described above, but does no work. In addition, in the state of the - time stop, the first

) is located inside.

Next, two wheelchair users (15) moved their wheelchairs onto the entrance floor (1).
e) to the treads of the movable treads (141) of the second wheelchair step (13) and the third wheelchair step (14), and turn the switch (23) on the wheelchair operation activation switch (23).
When b) is operated, the escalator is slowly started to horizontally move the wheelchair step group (11) in the transport direction, and the normal rotation pinion (I[i2) of the third wheelchair step (14) is moved to the rack (173). The wheel stopper (144) passes through both rear sides of the road surface of the movable footboard (141) and restricts the movement of the wheels of the wheelchair. Then, when the wheelchair step group (11) starts moving upward from horizontal movement, the movable step board (141) moves upward from the main body (140) as the second wheelchair step (13) rises. It is located on the same horizontal plane as the road surface of the wheelchair steps (13), and the remainder of the wheelchair form is formed (see FIG. 8).

However, after that, the escalator speeds up and
The motor (174) of the loading device (17) is driven in reverse to return the loading device (17) to its normal state.

Next, when the wheelchair step group (11) approaches the entrance floor (1d), which is the exit gate, the actuator (22) of the normal step (6A) contacts the exit day switch (19) and operates it, causing the escalator to is decelerated at a specific position, and the motor (174) of the loading device (17A) is driven in the same manner as described above to raise the rack (173) to a predetermined position. Then, when the wheelchair step group (11) starts moving horizontally from upward movement, the third wheelchair step group (14)
The movable footboard (141) of the main body (+
It is located on the same horizontal plane as the top surface of 401, and a part of the wheelchair form is released.

Next, the wheelchair step group (1 piece) moves horizontally to the entrance/exit floor (ldl), and when the reversing pinion (11i5) of the drive force transmission mechanism (16) successively engages with the rack (173), the drive force is transmitted. The mechanism (16) operates and the first, second,
The third wheelchair steps (12), (13), and (14) are each transformed from the wheelchair configuration to the normal configuration. This transformation operation will be explained in detail using the second wheelchair step (13) as an example.
The intermediate gear (65) meshes with the rack (173) and rotates in the E direction in the figure, and the forward rotation binion (162) meshes with the reverse rotation binion (lε5) rotates in the C direction and meshes with the rack (133). 168) - (168A) is rotated clockwise, and the pair of forks (132) retract and move in the direction of the arrow shown in the figure to release the engagement with the movable treadle (141).

The wheelchair user (15) then moves the wheelchair from the second and third wheelchair steps (13) and (14) to the entrance/exit floor (Itl). After that, the escalator speeds up and the motor (174) of the loading device (17A) is driven in reverse to return the loading device (17^) to its normal state, and the wheelchair step group (11) changes from normal to normal. The robot moves cyclically in the same normal manner as in (6) and (68), and repeats the above operations during wheelchair operation.

Next, FIGS. 15 to 18 show other examples of the conventional second and third wheelchair steps (13) and (14), in which (13) is the second wheelchair step (13) and (14).

The present invention has been made in view of the above, and an object of the present invention is to provide an escalator device that can improve passenger safety.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a fork that is arranged between a plurality of regular steps of an escalator and that can be retracted when operating a wheelchair is installed from the inside through a through hole of a cleat riser. a wheelchair step with a fork that protrudes rearward from the outside; a lid body equipped with a plurality of cleats that are attached to the tip of the fork and that close the through hole during normal operation and form part of a cleat riser; A wheelchair step with a movable tread that has a movable tread and is arranged adjacent to the rear of a wheelchair step with a fork, and a side part of a fork that is disposed in front of the lower surface of the movable tread and that protrudes when the wheelchair is operated. The device is characterized in that notches provided in the lid body to avoid collision with the connecting mechanism during operation of the wheelchair are cut out in the concave surfaces on both sides of the lid body.

[Effect]

According to the present invention, the notch provided in the lid body to avoid collision with the connecting mechanism when operating the wheelchair is made small on the concave surface on both sides of the lid body to prevent erosion of the convex surface of the lid body. This prevents the feet and shoes of ordinary passengers from getting caught in the notch.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in FIGS. 1 to 5. In the figure, (13) is a second wheelchair step,

I can do it. Further, since the continuity of the convex surface of the lid (134) can be ensured, the notch (135A) is not noticeable during normal operation, and the design can be significantly improved.

(Effects of the Invention) As described above, according to the present invention, the notch provided in the lid body to avoid collision with the connection mechanism during operation of the wheelchair is formed by small notches on the concave surfaces on both sides of the lid body. Since erosion of the convex surface is prevented, it is possible to provide an escalator device that can prevent the feet and shoes of general passengers from being caught in the notches.
