Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator device, and more particularly to an escalator device capable of raising and lowering a person in a wheelchair other than a pedestrian together with the wheelchair.

[0002]

2. Description of the Related Art An example of a conventional wheelchair-compatible escalator device is disclosed in Japanese Patent Laid-Open No. 7-2480. In the escalator device described in this publication, even a large-sized wheelchair user can use the escalator in three steps to form a vehicle step so that the escalator can be used without anxiety. Then, the lower step is raised to have the same height as the middle step, and the upper step is lowered to have the same height as the middle step to create a space in which the wheelchair can ride in a horizontal state.

Another example of a conventional wheelchair-compatible escalator device is disclosed in Japanese Patent Laid-Open No. 6-9188. In the escalator described in this publication, in order to improve operating efficiency, at least one of the steps that are connected endlessly and circulates is a special step for wheelchair mounting. After switching to wheelchair driving, the operating speed of the escalator is increased until the special step reaches the vicinity of the entrance / exit, and the escalator is made to travel at a very low speed at the entrance / exit when driving the wheelchair.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The one disclosed in Japanese Patent Publication No. 0 has a structure in which three steps are integrated so that the area of the steps can be widened and a wheelchair can be mounted. Therefore, it is necessary to incorporate a complicated mechanism for integration, ascent and descent in the steps. Three steps are set as a set, and the upper step and the lower step have different mechanisms. As a result, the cost and weight increase, and in practice, the mechanism can be installed only in a specific step of the series of steps, and the wheelchair can be mounted only in the place where the specific step is installed.

Therefore, when actually operating the escalator, when a person in a wheelchair arrives, a staff member is called at the boarding gate. Staff will block the escalator entrance to prevent pedestrians from boarding the escalator. After all the pedestrians have left the step, run dry until the step incorporating the coupling device is located at the boarding gate of the escalator.
When there is a wheelchair step at the boarding gate, stop the operation of the escalator and activate the step coupling mechanism. After that, the wheelchair is put on the board, and after confirming that the wheelchair is braked and the preparation is completed, the staff member operates the switch. When the escalator restarts and the wheelchair reaches the folding mouth, the staff member stops the escalator. When the wheelchair dismounts from the escalator, the steps are disengaged and normal driving is resumed.

The complicated procedure as described above is required, and it takes a long time from the arrival of the wheelchair to the escalator to the completion of the movement on the escalator. In addition, people in wheelchairs cannot board without the help of staff. Therefore, the mental burden on the passenger is large, and it is very difficult for a user in a wheelchair to use it.

In order to solve such a problem, in Japanese Unexamined Patent Publication No. 6-9188, when a user of an escalator of a wheelchair appears, the driving speed of the escalator is increased to shorten the time required for the pedestrian's escalator, and The speed of the escalator, which moves the steps at a slow speed, is adjusted to make it easier for people to get on. However, in this method, the operating speed of the escalator changes, which may cause anxiety to passengers. In addition, an attendant must check that a wheelchair passenger has arrived, which again imposes a heavy mental burden on the wheelchair passenger.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to enable a person in a wheelchair to board without waiting while trying to get on the escalator device.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram of an escalator device according to the present invention. If the moving direction of the escalator device 1 is up, the lower floor 2 side is the entrance and the upper floor 3 side is the exit, and if the moving direction is down, the upper floor 3 side is the entrance and the lower floor 2 side is the exit. Become. The landing plate has a double structure. As before, the first landing plate or fixed landing plate 4 is fixed to the floor. Below the first landing plate 4, a movable second landing plate or moving landing plate 5 is provided.

The position of the moving landing plate 5 on the entrance side does not move in normal operation. When the wheelchair 6 rides on the moving landing plate 5 and the passenger 7 operates the switch 8, a start signal is sent to the escalator control device 9. When any of the steps 10 reaches the predetermined synchronization position after the start signal is output, the moving landing plate 5 also starts moving at the same speed as the step 10. During the movement of the moving landing plate 5, the guide rails 11 keep the moving landing plate 5 horizontal.

When the moving landing plate 5 reaches the exit, the moving landing plate detecting means 12 provided near the exit detects the moving landing plate 5. The detected signal is sent to the escalator control device 9. The escalator control device 9 releases the synchronization between the moving landing plate 5 and the steps 10 and stops the moving landing plate 5. When the moving landing plate 5 is stopped, the passenger of the wheelchair 6 moves the wheelchair from the moving landing plate 5 to the floor surface via the fixed landing plate 4 by himself. A plurality of moving landing plates 5 are prepared as needed, and are sequentially replaced.

The wheelchair 6 must be stopped and braked before boarding the escalator to confirm safety. Therefore, conventionally, the step 10 has been stopped. According to the present embodiment, since the moving step 10 and the stationary landing plate 5 are separated, the wheelchair 6 may be prepared not on the step 10 but on the moving landing plate 5. It is not necessary to stop the steps 10 during preparation. Therefore, a pedestrian who rides in front of the wheelchair can move to the exit as it is. Further, since it moves in synchronization with any step 10, there is no need for idle operation. Further, conventionally, it was necessary to wait for a maximum of one round until the synchronization position came, but this is not necessary in this embodiment. As a result, if the switch 8 is operated, the movement can be started immediately.

According to this embodiment, the person behind the wheelchair is not kept waiting for a long time. Further, since it is not necessary to block the entrance of the escalator to exclude the pedestrian from the escalator, it is not necessary to have an attendant perform the operation of blocking the entrance or the idling operation. Wheelchair passengers can use the escalator device by themselves and do not have to wait until an attendant arrives. In addition, the moving landing plate 5 at the exit
Is automatically stopped so that the wheelchair can safely exit the escalator. That is, according to this embodiment, the escalator can be smoothly used in the wheelchair. Further, since the use of the escalator by other pedestrians is not hindered, the psychological burden on the user can be reduced.

FIG. 2 shows the moving landing plate 5 used in the escalator device shown in FIG. Wheels 13 are attached to both side surfaces of the moving landing plate 5 on one end side in the longitudinal direction. A coupling pin 14 is attached to the other end of the movable landing plate 5 in the longitudinal direction. The moving landing plate 5 is coupled to the step 10 and moves.

3 and 4 show the details of the connecting portion of the step 10. A main wheel 16 driven by a chain 15 is provided on the upper part of the step 10, and an auxiliary wheel 17 for keeping the step 10 horizontal is provided on the lower part. Movement paths of the main wheels 16 and the sub wheels 17 are determined by dedicated S-shaped guide rails 18 and 19. The shaft 20 of the main wheel 16 has a hook 21 for coupling with the moving landing plate 5.
Are rotatably mounted within a limited angle.
The hook 21 is L-shaped, and a notch that connects the hook 21 to the pin 14 of the moving landing plate 5 is formed on one arm. A pin 22 that drives the hook 21 is attached to the other arm of the hook 21.

A push spring device 24 is attached between the hook 21 and the frame 23 extending below the step 10 to form a toggle link mechanism. That is,
The hook 21 is arranged so that the hook 21 is in the leftmost state in FIG. 4, or in the middle or rightward state.
Pressed at 4. When the cam 25 pushes the pin 22 upward, the state shown in the step 10a on the left side of FIG. 4 is established, and the step 10a and the moving landing plate 5 are connected. When the cam 25 pushes down the pin 22, the middle step 10b or the right step 10c is established, and the connection between the step 10b or step 10c and the moving landing plate 5 is released. The cams 25 are located at the upper end portion and the lower end portion of the escalator device 1, and are arranged at positions suitable for coupling or releasing. Then, it moves up and down as needed.

FIG. 5 shows a state in which the step 10a and the moving landing plate 5 move while being connected to each other. Step 10
a moves by the guide rails 18 and 19 while maintaining the horizontal state. Wheels 13 of moving landing plate 5
Has a substantially same shape as the guide rails 18 and 19, and a movement path is defined by a guide rail 26 provided parallel to the guide rails 18 and 19.

FIG. 6 shows the lower end portion of the escalator device of this embodiment. The moving landing plate 5 circulates around the escalator device 1. It is assumed that one moving landing plate 5a is coupled to the step 10a by the cam 25 at the first stop position (not shown). The landing plate 5 is pulled by the step 10a so that the step 10a
Rises with. Other moving landing plate 5b
Is pushed to the stop position by the moving landing plate 5c behind it. The movable landing plate 5c is positioned by the drive mechanism of the rocking device 27, the details of which will be described later.

FIG. 7 shows details of the rocking device 27 provided at the most distal end of the elevator device. The swing device 27 is a position drive control device 28 that drives the moving landing plate 5.
And a gripping device 29 for gripping the movable landing plate 5

In FIG. 6, the moving landing plate 5c is shown.
The movements of are displayed in an overlapping manner. The movable landing plate 5c is held by the tray 30 and is transported from the upper portion of the escalator device 1 through the lower side of the escalator device 1. The moving landing plate 5c, which has moved to the terminal end, reaches the rocking device 27, which is arranged downward in advance, because the wheels 13 are scooped up by the guide rails 31. The rocking device 27 uses the gripping device 29 to grip and pull up the moving landing plate 5c. Swing device 27
When is raised to the horizontal position, the rocking device waits until the timing of pushing out the movable landing plate 5c. The tray 30 is driven by the wire 32. Tray 30
Is pulled rightward by the wire winding device 33 with an appropriate force.

FIG. 8 shows the upper end portion of the escalator device. The moving state of the moving landing plate 5a is displayed in an overlapping manner. The moving landing plate 5a is
Move to horizontal movement at the upper end. Then, the other moving landing plate 5d placed on the upper end is pushed out. When reaching the predetermined stop position, the cam 25 releases the connection between the step 10a and the moving landing plate 5a. When the connection is released, the moving landing plate 5a remains in the released position.

The other movable landing plate 5d pushed out is drawn into the circulation path of the escalator device 1 by the rocking device 27 provided at the left end of the escalator device 1. At this time, the rocking device 27 tilts and pushes the movable landing plate 5d obliquely downward. The movable landing plate 5d pushed out is mounted on the tray 30. A wire driving device 34 drives the tray 30.
The tray 30 moves along a guide rail 35 that constitutes a lower portion of the escalator device 1 and is carried to the lower end portion of the escalator device 1. In this way, since the moving landing plate 5 circulates around the escalator device 1,
The wheelchair 6 and its passenger 7 can be carried.

Although the above description is for the upward escalator device, in the case of the downward escalator device, the procedure reverse to the above procedure may be performed. That is, if the downward escalator is shown in FIG. 6, the moving landing plate 5a
Descends to the lower right in the figure. At this time, the lowered landing plate 5a may be overlaid on the existing moving landing plate 5b. Therefore, the cam 25 is used to connect the step 10b and the movable landing plate 5b. As a result, the moving landing plate 5b is pulled below the fixed landing plate 4. And
When the movable landing plate 5b reaches a predetermined position, the cam 36 provided separately releases the coupling.

When the wheelchair 6 is mounted on the movable landing plate 5, the wheelchair 6 is moved by the movable landing plate 5.
Operate the bollard to prevent it from falling off. FIG. 9 shows details of the car stop. A hinge joint is provided at the right end of the movable landing plate 5, and the car stop 37 is rotatably attached to the landing plate 5 at the hinge joint.
The car stop 37 is formed in a concave shape, and the projections 3 at both ends are formed.
8 forms an arm. A guide wheel 39 is attached to the side of the protrusion opposite to the hinge.

FIG. 10 shows a moving state of the guide wheel 39. The guide wheel 39 moves on the S-shaped guide rail 26 on which the wheel 13 supporting the moving landing plate 5 moves. When the S-shaped guide rail 26 is horizontal, the car stop 37 is in a substantially horizontal storage position. On the other hand, when the movable landing plate 5 reaches the diagonal portion of the S-shaped guide rail 26, the car stop 37 is tilted upward to the operating position. When the movable landing plate 5 moves, the car stop 37 automatically operates, so that no special drive means for operating the car stop 30 is required.

Another embodiment of the escalator device according to the present invention is shown in FIG. This embodiment is different from the above embodiment in that the movable landing plate 5 is vertically divided into two parts, a movable landing plate 5A and a movable landing plate 5B. That is, the movable landing plate 5A and the movable landing plate 5B can be folded by hinge coupling.

An example of operating the foldable movable landing plates 5A and 5B is shown in FIG. The moving landing plate 5 is not under the fixed landing plate 4 but at the same height, unlike that shown in FIG. Then, it reciprocates back and forth between the upper and lower fixed landing plates 4, 4. When returning the movable landing plate 5, the movable landing plate 5 is folded and stored along the side surface of the escalator device 1 and moved in the direction opposite to the step 10.

In order to reverse the moving direction of the step 10 and the moving direction of the moving landing plate 5, the wheel 40 is attached to the side surface of the moving landing plate 5 on the back side. The wheels 13 attached to the front side of the moving landing plate 5 are guided by the S-shaped guide rails 26 to move.
On the other hand, the wheel 40 attached to the back side of the movable landing plate 5 moves while being guided by another S-shaped guide rail 41 arranged in parallel with the S-shaped guide rail 26. The movable landing plate 5 is kept horizontal by the two S-shaped guide rails 26 and 41. The moving landing plate 5 is driven by the chain 42 mounted on the shaft of the wheel 13 as in the step 10.

Details of the chain portion for driving the movable landing plate 5 are shown in FIG. The chain 42 includes an inner link plate 43, an outer link plate 44, and a roller 45. Each of these members 43 to 45 is connected by a pin. A shaft 46 passing through the moving landing plate 5 passes through the outer link plate 44 and supports the wheel 13. The wheels 13 move while being guided by the S-shaped guide rails 26, but the chains 42 do not follow the route because they are straight even in curved portions. Therefore, a chain guide 47 is provided above and below the chain 42 to define the chain path.

FIG. 14 shows details of the path of the chain 42. A chain guide 47 is provided on either or both of the upper side and the lower side of the chain 42. The chain 42 goes around the escalator device 1 along the chain guide 47. Drive sprocket 4 provided at the corner of the movement path of the chain 42
8 drives the chain 42. Since the moving landing plate 5 only reciprocates between the upper landing (landing) and the lower landing (landing), the chain 42
Will also reciprocate. Therefore, the chain 42 does not necessarily have to go around the escalator device 1 once, and may be wound by both ends. According to the present embodiment, the escalator device that is not wheelchair compatible can be easily modified to be wheelchair compatible without modification.

Still another embodiment of the present invention is shown in FIG. The present embodiment is different from the above embodiments in that the movable landing plate 5 is laterally folded in three, and the bent portion is a hinged joint structure. Of the two hinge structures, the one on the tip side may be the same as the car stop 37 shown in FIG. The movable landing plate 49 of the three-piece structure bends only inward, and does not warp outward from a straight state. When one moving landing plate 49a approaches, the tip of the other moving landing plate 49b is connected to the step 10d by the cam 25. And
Go under the escalator device 1. At this time, the wheels 13 and 39 are guided by the guide rail 50 so as to rotate around the outside of the step 10d of the escalator. The moving landing plate 49b is pulled by the step 10d and arrives at the lower end portion of the escalator device 1. When the moving landing plate 49b reaches the standby position at the lower end,
To cancel the bond. According to this embodiment, it is not necessary to separately prepare a drive system for the movable landing plate 5, and a compact structure can be achieved.

FIG. 16 shows still another embodiment of the present invention. The present embodiment is different from the above embodiments in that the moving landing plate 51 is shortened and connected to the rear end of the step 10. Since the moving landing plate 51 has been shortened, it is convenient for patrol.

By the way, in order to automatically move the escalator device 1, it is necessary to provide various protective safety equipment. FIG. 17 shows an example of protection and safety equipment. When the moving landing plate 5c approaches the upper end portion, the moving direction of the moving landing plate 5c changes from the diagonal direction to the horizontal direction. At this time, the gap between the moving landing plate 5a and the steps 10b and 10c becomes narrow. If a pedestrian's foot or luggage enters this gap, it may be caught. Therefore, a large number of non-contact obstacle detecting means 52, 52, ... Are arranged on the inner surface of the escalator device 1. Each detecting means 52 has a movable landing plate 5a.
Detects whether there is an obstacle in the narrowed gap due to movement. Information on this obstacle is sent to the escalator control device 9.

When the obstacle is on the steps 10b, 10c, a warning is issued by using a voice guide or a buzzer. Or slow down the escalator or stop the escalator to ensure safety. The obstacle detection means 52 is, for example, an optical sensor, and detects an obstacle by blocking the beam of light or capturing reflected light to detect the presence or absence of an object.

In order to synchronize the moving landing plate 5c with the obstacle detecting means 52, for example, a proximity sensor capable of detecting metal may be used. A plurality of moving landing plate detection means 53 are provided on the inner wall of the escalator device 1. Then, the moving landing plate detection means 53
Determines whether or not there is an obstacle by selecting only the signal from the obstacle detecting means 52 capable of detecting an obstacle above the steps 10b and 10c.

18 and 19 show specific examples of measures against foreign matter intrusion. FIG. 18 is a perspective view showing the vicinity of the boarding port of the escalator device 1. FIG. 18 shows a state where the moving landing plate 5 is moving. As shown in detail in FIG. 19, the skirt guides 56 provided on both sides of the step 10 have an opening groove 55 through which a shaft 68 connecting the movable landing plate 5 and the guide roller 13 passes.
Is provided. The groove 55 is formed in a shape that allows the shaft 68 to pass according to the movement trajectory of the moving landing plate 5.

If the opening groove 55 is left in the open state, there is a risk that a pedestrian may pinch an object or a foreign object may enter and cause a failure. Therefore, when the moving landing plate 5 is stopped at the entrance / exit and a pedestrian uses a step, the opening groove 55 is closed using the shutter plate 60 provided inside the balustrade 57 of the skirt guard 56.

When the moving landing plate 5 starts moving, a plurality of moving landing plate detecting means 53 arranged on the skirt guard 56 sense the approach of the moving landing plate 5. Then, a control device (not shown) excites the electromagnet 63 provided inside the balustrade 57 and attracts the armature 66 fixed to the upper portion of the shutter plate 60. When the armature 66 is attracted, the shutter plate 60 moves upward by using the guide pin 64 as a guide and against the spring force of the return spring 62.

After the moving landing plate 5 has passed through the moving landing plate detecting means 53, when another moving landing plate detecting means senses the approach of the moving landing plate 5, the excitation of the electromagnet 63 which has been excited until then is stopped. . When the excitation of the electromagnet 63 is stopped, the return spring 62 lowers the shutter plate 60 so as to close the opening groove 55. Then, when it reaches the upper surface of the holding plate 61 provided inside the balustrade 57, it stops. Thus, the opening / closing mechanism 58 for opening / closing the opening groove 55 in the balustrade interior 57.
Since it is provided, the opening groove 55 can be closed in a place other than the position of the moving landing plate 5.
As a result, foreign matter can be prevented from entering the opening groove 55.

Another method of closing the opening groove 55 is shown in FIGS. Specifically, the rubber plates 69a, 6
9b is provided in the opening groove 55 portion formed by the skirt guard 56. In FIG. 20, the opening groove 55 is provided with rubber plates 69a, 6a.
9b shows a closed state. Moving landing plate 5
This is applicable when the pedestrian uses the escalator when the car is stopped. FIG. 21 shows a state in which the moving landing plate 5 is moving. Moving landing plate 5
The shaft 68 connected to the movable landing plate 5 passes while spreading the rubber plates 69a and 69b. As a result, the opening groove 55 is formed between the rubber plates 69a and 69b only in the portion where the shaft 68 is passing, and the opening groove 55 is closed where there is no moving landing plate 5. According to the present embodiment, it is possible to avoid the entry of foreign matter with a simple structure.

It should be noted that each of the above-mentioned embodiments is illustrative and not restrictive. The scope of the invention is set forth in the claims, and all variations that come within the meaning of the claims are included in the invention.
