There was one in which wheelchair steps placed in the main frame were connected in an endless manner and circulated through a circulation path provided in the main frame. The above-mentioned escalator with steps for wheelchair passengers carries general passengers in the same manner as normal steps during normal operation, and when operating in a wheelchair, the movable treads, wheel stops, and inclined treads provided on the steps for wheelchair passengers are used. A movable body such as a person with a physical disability is raised and lowered to transport the wheelchair with a physically disabled person on it using wheelchair steps, and even when driving the wheelchair, general passengers other than the wheelchair user are often transported using normal steps. In addition, when driving in a wheelchair, in order to operate movable objects such as treads, car stops, and inclined treads, it is necessary to temporarily stop the escalator at the entrance and exit area, and then manually operate the drive source such as the electric motor. As a result, the movable body is operated at the entrance and returned to its original position at the exit.

When a physically disabled person in a wheelchair or his or her caregiver operates the wheelchair operation selector switch to switch from normal operation to wheelchair operation, the normal steps and the wheelchair passenger step group travel, and the actuator operates the entrance switch. When activated, the wheelchair passenger step group stops at the appropriate position at the entrance, and the movable body automatically moves to raise the platform rack and place the wheelchair passenger step group at the desired position on the rack. When one of the two reversing pinions engages or becomes engageable, the wheelchair rides on the wheelchair step group, and the wheelchair operation start switch is operated, the movable body operates and the wheelchair moves in a stable state together with the physically disabled person. transport. Also, when the actuator operates the exit switch, the exit rack automatically rises at the exit, and the other of the forward and reverse pinions engages with this rack, and the movable body returns to its original position, allowing the wheelchair to step away from the wheelchair step group. The wheelchair can be dismounted. In this case, the wheelchair descends from the wheelchair passenger step group to the entrance floor. Even if you fail, the treads of the following steps remain horizontal, so there is no problem getting down. Therefore, although the escalator is stopped at the entrance to maintain safety, there is no need to stop the escalator at the exit, and the wheelchair can get off the escalator while it is still running.Furthermore, with the actuator and switch,
The movable body can be operated and returned by automatically raising the boarding and dismounting racks.

Further, the step 6 is provided with a driving force transmission mechanism including a forward rotation pinion 15 and a reverse rotation pinion 16 for raising and lowering a wheel stop 32 protruding onto the movable step plate 28a, and the step 4 is provided with an inclined step plate which is a movable body. A driving force transmission mechanism including a forward rotation pinion 15 and a reverse rotation pinion 16 is provided in order to incline the gear so that the rear part thereof is located downward, and these driving force transmission mechanisms are connected to the step 5
This is almost the same as the driving force transmission mechanism 19 provided in . Furthermore, a wheelchair operation changeover switch 40 and a wheelchair operation start switch 41 are provided at the upper and lower end portions of the parapets 34 erected on both sides of the circulation path 2 of the main frame 1. An entrance switch 42 for ascending operation is arranged at the lower end of the return route 2C of the circulation path 2, an exit switch 43 is arranged at the upper end of the outward route 2a, and an exit switch 43 for the exit during descending operation is arranged at the upper end of the return route 2C. A switch 44 is disposed, and an exit switch 45 is disposed at the lower end of the outgoing path 2a, and the switches 42, 43, 44° 45 are position detection IJEs that are operated by contact with the actuator 51 provided on the step 7. These are switches, and each is fixed to the main frame 1 side. In addition, in the figure, 46 and 47 are entrance floors, 48 is a wheelchair, and 4
9 and 50 are comb-shaped. Also, of the configuration of this embodiment, the configuration other than the lifting mechanism 12, racks 13, 14, pinions 15, 16, and driving force transmission mechanism 19 is disclosed in Japanese Patent Laid-Open No. 60-23283 and Japanese Patent Laid-Open No. 60-23285. It is almost the same as the conventional one shown in et al. Next, the operation of this embodiment configured as above will be explained. During the ascending operation, the operations shown in FIGS. 10 and 11 are performed. That is, the physically handicapped person or caregiver riding on the wheelchair 48 presses the wheelchair operation changeover switch 40 to switch the escalator from normal operation to wheelchair operation, and at the same time, the wheelchair 48 is made to wait on the boarding/exiting floor 46 at the lower end. When the wheelchair passenger steps 4° 5, 6, 7 travel and approach the entrance, the actuator 51 provided on the wheelchair passenger step 7 for position detection comes into contact with the entrance switch 42 and operates the switch 42. , the escalator is decelerated at a specific position, and the electric motor 35 of the elevating mechanism 12 disposed at the lower end 1b of the main frame 1 is driven to rotate in the normal direction, and the driving pinion 36
By rotating in the normal direction, the rack 13, which serves as a riding rack, rises to a predetermined position via the rack shaft 37. The forward rotation pinions 15 of the wheelchair steps 4 and 5 that are running at a reduced speed mesh with the ascending rack 13, inclining the inclined tread 33, and pushing out the fork 25, forming a part of the wheelchair step. . In other words, the normal rotation pinion 15 of the step 5
meshes with the rack 13, and the rack 13 is fixed, but the normal rotation pinion 15 along with the step 5 is rotated by the arrow A in FIG.
direction, the pinion 15 rotates in the clockwise direction shown by arrow B, and the fork 25 rotates through the intermediate gear 21.
is pushed backwards as shown by the arrow, and the step 6 with a movable body is pushed out.
The movable body 28 is inserted into the holes 29a and 30a of the fork receivers 29 and 30 in the lowered state. In addition, forward rotation pinion 1
5 causes the reversing pinion 16 to rotate counterclockwise, but the reversing pinion 16 does no work. Further, the above-mentioned operation is performed at the lower end of the outgoing path 2a of the circulation path 2 where the tread 5a of the step 5 with an operating mechanism and the movable tread 28a of the step 6 with a movable body are located on the same horizontal plane, and the fork 25 is engaged with the fork receivers 29 and 30,
In this state, the escalator stops at the entrance. At this stop position, the inclined tread 33 of the step 4 is inclined but does not protrude above the movable tread 28a of the step 6. In this state, when the wheelchair 48 is placed on the tread 5a of the step 5 and the movable tread 28a of the step 6 from the entrance floor 47 and the wheelchair operation start switch 41 is turned on, the escalator is slowly started. As a result, the normal rotation pinion 15 of the step 6 traveling at low speed
is engaged with the rack 13, and the wheel stopper 32 protrudes above the movable tread 28a. When the rear step 5 reaches the inclined part of the outward path 2a, the movable body 28 rises with respect to the step body 31 of the step 6 with a movable body as the tread 5a rises. However, the escalator increases its speed and ascends while the tread plate 5a and the movable tread plate 28a remain on the same horizontal plane, and the remaining steps for wheelchair passengers are formed. At a proper time after the bollard 32 has been raised, the electric motor 35 of the elevating mechanism 12 provided at the lower end of the main frame 1 is driven in reverse to return the rack 13 downward, and the escalator speeds up and travels upward. When the wheelchair steps 4, 5, 6, and 7 approach the exit,
The actuator 51 of the step 7 contacts the exit switch 43 and operates the switch 43, decelerating the escalator at a specific position, and the electric motor 35 of the lifting mechanism 12 disposed at the upper end of the main frame 1 is activated. The rack 14, which turns into a lower rack, rises to a predetermined position. The reversing pinion 16 of the wheelchair step 4° 5.6 which is running at a decelerating speed sequentially meshes with this rack 14, thereby returning the inclined step board 28a, fork 25 and wheel stop 32 to the state before operation. That is, the reversing pinion 16 of the step 5 is connected to the rack 14.
The forward rotation pinion 15 rotates counterclockwise as shown by arrow C as shown by arrow E in FIG.
The fork 25 is pulled forward as shown by arrow F via the intermediate gear 20, extracted from the fork receiver 19.30, and stored below the footboard 5a. Therefore, the movable body 28 of the step 6 with a movable body descends relative to the main body 31 of the step, and the movable tread 28a is located on the same horizontal plane as the tread 5a, and the upper horizontal part of the outgoing path 2a is aligned with the arrow in FIG. Move in the direction shown in A. Then, the wheelchair 48 is lowered onto the entrance/exit floor 47 from above the step board 5a and the movable step board 28a. The movable tread 28a passes through the comb-shaped body 50 at the upper end while keeping the downward descending state, and the rack 14 is lowered by the operation of the elevating mechanism 12 at the upper end of the main frame 1, the escalator accelerates, and moves to the reversing section 2b and returning. *2c
It returns to the lower end of the outward path 2a via the p-inversion section 2b, and repeats the above-described operation. During descending operation, the actuator 5 of the wheelchair passenger step 7
1 is the switch for riding 44. The exit angle switch 45 is sequentially contacted, and the operation of these switches 44 and 45 is almost the same as that during the above-mentioned operation, but when the step 3
, 4, 5, 6, and 7 are reversed from those during upward operation, the reversing pinion 16 meshes with the rack 14 that is rising at the upper end of the main frame 1, and the fork 25 moves into the fork receiver 29.30. When the normal rotation pinion 15 engages with the rack 13 raised at the lower end of the main frame 1, the fork 25 is disengaged from the fork receivers 29 and 30 and stored. In addition, during normal operation, the movable footboard 28a maintains a downwardly descending state because the lifting mechanisms 12, 1.2 do not operate, and the step 4
, 5, and 6 can also carry general passengers in the same way as step 3. In the embodiment described above, the escalator is temporarily stopped when the user gets on the vehicle, but is not stopped when the user exits the vehicle. Since the escalator is decelerated when boarding and disembarking, the rack being raised by the elevating mechanism and the forward and reverse pinions provided on the steps are surely engaged with each other.In this invention, the deceleration of the escalator is , it is not necessary to do so. The reason why the wheelchair is stopped once when getting on the wheelchair is to prevent the wheelchair from stepping on the wrong step if the next step is a normal step and the wheelchair cannot get on, which could be dangerous. Even if you fail to get off to the entrance floor, there is no safety problem because the treads of the following normal steps will also remain level. In the present invention, the steps with movable bodies may be omitted from those with inclined treads, and the operating mechanism can be changed as appropriate. Further, in the present invention, the elevating mechanism 12.12 of the racks 13, 14 can be an electromagnetic plunger or a hydraulic cylinder mechanism, and a normal step is provided between the step provided with the actuator and the step having a forward rotation pinion and a reverse rotation pinion. may be interposed. -16=

The entry and exit racks are raised, and the forward rotation pinion and reverse rotation pinion provided on the steps of the wheelchair passenger step group are engaged with these racks to operate and return the movable body of the wheelchair passenger step. The escalator is stopped only when the escalator is stopped, the wheelchair is placed on the wheelchair step when the escalator is stopped, and the escalator is started.At the exit, the wheelchair descends while the escalator remains in operation.This improves the driving ability of the wheelchair user. Also, the raising of the rack and the movement of the movable body due to this. Since the return can be automated, an escalator with steps for wheelchair passengers that can be easily operated can be obtained.
