DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator device which can be shared by ordinary customers and wheelchair users, and more particularly to an escalator device having a step suitable for mounting a wheelchair.

[0002]

2. Description of the Related Art Conventional escalator devices that can be mounted on a wheelchair are disclosed in, for example, Japanese Patent Application Laid-Open No. 4-209194.
A wheelchair in which the movable step of the step adjacent to the lower side of the specific step is raised to the same height as the step of the specific step, and the step of the step adjacent to the upper step of the specific step is inclined to the level of the step of the specific step. The mounting surface is secured.

[0003]

In the above prior art, the riser attached to the specific step is moved downward by one step because the step of the step adjacent to the upper step of the specific step is inclined by one step. I have to do it. Therefore, the riser is configured to be bent from the middle so that the lower end of the riser does not interfere with the steps on the return side.
However, the structure in which half of the height of the riser is bent complicates the bending structure and must be moved downward while bending, which complicates the operation. However, there is a problem that the height of the main frame must be larger than the height of the main frame of a general escalator device so that the steps on the return side do not interfere.

An object of the present invention is to provide an escalator device capable of securing a wheelchair mounting surface without changing the height of the main frame.

It is another object of the present invention to provide an escalator device which can simplify the structure and operation of an inclined tread.

It is still another object of the present invention to provide an escalator device capable of securing a mounting surface for a wheelchair by reducing the inclination angle of an inclined tread.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a stepping plate which normally rises to form a wheelchair mounting surface during a wheelchair transport operation by driving a plurality of adjacent specific steps connected between the steps. A second step provided with a first step provided and an inclined step board which is adjacent to the upper side of the first step and whose inclined lower end is inclined so as to approach the upper end of the wheelchair mounting surface.
The inclination with, the wheelchair transfer operation configured in the footstep of
A mechanism is provided for engaging the swash plate with the first step and maintaining the lower end of the slope at the height of the wheelchair mounting surface.

[0008]

According to the above construction, since the stepboard of the upper step is inclined with respect to the stepboard which has been raised to secure the wheelchair mounting surface, the inclination angle of the stepboard is small, and as a result, the lower part of the riser The main frame does not protrude below the step running guide rail, and the height of the main frame can be the same as that of a general escalator device. Further, since the inclined step board has a small inclination angle, the lower end of the riser does not protrude toward the return side of the step even if the riser is not bent, so that the configuration and operation of the inclined step board can be simplified.

During normal operation, as shown in FIG. 4, the movable treads 10A and 10C are placed on the movable tread 10B. Are folded so as to overlap. In the folded state, the surface 1 of the movable treads 10A, 10C
0S is configured to be flush with the narrow tread plate 11.

The movable step board 10B includes a base 4B.
(Shown in FIGS. 1 and 6) is supported so as to be able to ascend and descend by an elevating mechanism 12 such as a cross-link mechanism, and the movable tread 10A is
With the rise of B, the state is folded from the state of being folded by the deploying mechanism including the deploying arm 13, the connecting link 14, and the connecting pin 15 to 1
It is configured so that the wheelchair mounting surface is formed with the movable tread plate 10B after being deployed by 80 degrees.

The lifting mechanism 12 is driven by a driving device 16 supported on a base 4B of the step 4. The driving device 16 faces the stop position of the step 4 at the upper and lower entry / exit portions, and the main driving device 16 is driven by the main device. Power supply (not shown) provided in frame 2
Powered by and driven.

On the other hand, as shown in FIGS. 1, 4 and 5 to 10, the configuration of the specific step 5 includes an inclined step board 17. The inclined tread 17 is configured to be able to incline while leaving a narrow tread 18 and a riser 18R connected thereto on both sides of the specific step 5 in the width direction. The inclined tread 17 is provided integrally with a riser 17R having the same width, and the anti-riser 17R side of the inclined tread 17 is inclined via a support shaft 19 to an inner wall body 18W connecting the narrow tread 18 and the riser 18R. Supported as possible.

The inclined tread 17 is provided with tread support rods 20 protruding toward the inner wall body 18W on both sides in the tread width direction on the back side thereof. This tread support rod 2
0 supports the inclined tread 17 so as to be flush with the narrow tread 18 during normal operation, as shown in FIG. 7. Are engaged with engagement holes 18H provided in the inner wall body 18W. Further, the tread plate support rod 20 is, for example, a driving machine 21 having a function of an electromagnetic plunger and a function of an electric motor.

As shown in FIGS. 4 and 5, the tilt maintaining arm 24 closes the surface of the riser 17R with its tip 24E during normal operation and immediately before the wheelchair is transported. As shown in FIG.
The specific step 4 which penetrates the riser 17R and is adjacent to the lower step with the guide 17G provided on the riser 17R side of
4B after the tread surface expansion tread 10 (10B) of the tread has risen
Has a length in contact with Although the inclination angle of the inclined step board 17 is regulated by the projection of the step board support rod 20, if the step board support rod 20 does not project for any reason, the regulation of the inclination of the inclined step 17 is restricted. Without this, the lower end of the riser 17R moves further downward beyond the guide rail 9B. In order to eliminate such inconvenience, a stopper 26 is provided on the inner wall body 18W so that the slope of the inclined tread 17 stops at a position where the lower end of the riser 17R of the inclined tread 17 does not project below the guide rail 9B. Are engaged with each other.

When normal operation is performed with the escalator device configured as described above, the movable step board 10 of the specific step 4 is used.
The tread-enlarged treads 10 are folded so that the surfaces 10S of A and 10C are at the same height as the narrow treads 11, and the inclined treads 17 of the specific steps 5 are also horizontally so as to have the same height as the narrow treads 18. Is held. By moving the steps including the normal steps 3 in such a state, ordinary customers can use the same as ordinary escalator devices.

Next, when performing a wheelchair transfer operation from the lower floor 1D to the upper floor 1U, if a wheelchair transfer operation command is issued by a button operation of a staff member or a wheelchair user, as shown in FIG. Steps 4 and 5 are the floor 1P of the lower floor 1D
Stop at a position close to. The stop position is the horizontal section a of the guide rails 9A and 9B in the specific step 4, and there is no step between the specific step 4 and the subsequent normal step 3. However, the specific step 5 has already entered the concave curved section b of the guide rails 9A and 9B, and has stopped at a position higher than the specific step 4 following the step H.
₁ is in a state where it occurs. At that time, usually the step 3 Yuku previous special step 5 has entered the inclined section c, predetermined step H ₂ is generated which occur during normal operation between the special step 5. In this case, step plate usually the step 3 following the special step 4 are L ₁ size exposed from the distal end of the landing floor 1P. The L ₁ dimension, the movable step plate 10C of the tread extension step board 10 to be described later
When the vehicle is deployed, it is overlapped on the floor 1P, so that there is no large gap between the floor 1P and the floor 1P. The specific step 4 and the subsequent normal step 3 are the same as those of a general escalator device. This is the same as a state in which approximately one and a half treads are connected horizontally from the landing floor 1P.

When the stop of the specific steps 4 and 5 is confirmed at the above-mentioned position, a power supply unit (for example, a power supply plug) connected to a power supply provided on the main frame 2 facing the drive unit 16 of the specific steps 4 (Not shown) automatically moves toward the terminal of the driving machine 16 and connects. By connecting this power supply, the drive 1
6 is driven to operate the lifting mechanism 12 to expand the tread surface
Increase 0. Due to this rise, as shown in FIG.
The movable step board 10A is turned 180 degrees by the deployment mechanism including the deploying arm 13, the connecting link 14, and the connecting pin 15 to form a horizontal wheelchair mounting surface with the movable step board 10B. At this time, the movable tread 10C is inclined so as to be in contact with the floor 1P, as shown in FIG. 3, to facilitate the loading of the wheelchair 27. Incidentally, if the front wheel 27F of the wheelchair can easily get over the movable tread 10C when the wheelchair is carried in, the movable tread 1 is not necessarily required.
There is no need to contact 0C with the floor 1P. Also, increased dimensions H ₃ tread extension step board 10 is reversed deployed movable tread plate 10A
There boarding floor 1P to a dimension of the height H ₄ can be secured without contact, special step 4 in this dimension the stop position,
It is substantially equal size as the step H ₁ between 5.

Simultaneously with the formation of the wheelchair mounting surface by the specific step 4, the driving device 21 of the specific step 5 is supplied with electric power through the lead wire 23 connected to the power supply section of the specific step 4, and rotates the step board support rod 20. While pulling it toward the center of the step. The operation of the tread plate support rod 20 causes the small gear 2
The tilt maintaining arm 24 is moved via the rack 2 and the rack 25, and its tip 24E is projected from the surface of the riser 17R, so that the base 4B after the tread-extended tread 10 of the specific step 4 located on the lower side is raised. On the upper surface 4P. On the other hand, the leading end 20E is pulled out from the engaging hole 18H provided in the inner wall body 18W of the narrow tread plate 18 by the pulling of the tread plate support rod 20, so that the inclined tread plate 17 loses the horizontal support force and the support shaft 19 is moved. It becomes possible to rotate (tilt) as a center. However, the inclination maintaining arm 24 is mounted on the base 4 of the specific step 4.
Since it is engaged with the upper surface 4P of B, the inclined tread 17 is not inclined and is maintained horizontal.

In such a state, the wheelchair 27 is put on. That is, as shown by the two-dot chain line in FIG. 3, the wheelchair 27 is pushed onto the developed movable treads 10A to 10C from the floor 1P. Next, as shown in FIG.

It will be R-car stop.

Next, by operating a start button (not shown) for the wheelchair transfer operation and giving a restart instruction, the wheelchair transfer operation is started and the guide rails 9A and 9A are operated.
The vehicle enters the inclined section c shown in FIG.
At this time, the predetermined step H ₂ is produced in normal operation between the step board of each footstep 3,4,5, between the said special step 4, 5 of the wheelchair transfer operation, the movable tread plate 10A, 10B
Since There has been an increased H ₃ dimensions, the movable tread plate 10A, 1
Step between the narrow step plate 18 of the special step 5 and 0B becomes H ₅ dimensions. The H ₅ dimension, [H ₂ - (H ₃ + movable tread plate 10A
Thickness)]]. Then, the slope maintaining arm 24 at the tip of the inclined step board 17 follows the upper surface 4P of the base 4B of the specific step 4 with respect to the spread of the step between the specific steps 4 and 5 from the concave curved section b to the inclined section c. Descend. Inclined step board 17 by the lowering of the inclination maintaining arm 24 is tilted about the support shaft 19, the step of H ₅ dimensions between the riser end of narrow step plate 18 of the special step 5 and the riser end of the inclined tread plate 17 make. Incidentally, the inclination of the inclined tread plate 17, but the lower end of the riser 17R continuing to move downward by H ₅ dimensions, since the reduced H ₅ dimensions by raising the movable tread plate 10A, the 10B, descent amount It can be made smaller and does not descend beyond the guide rail 9B. by this,
Riser side end (inclined lower end) of the inclined tread 17 and the movable tread 1
OB is held at substantially the same position. Therefore, a large gap does not occur between the inclined tread 17 and the movable tread 10B, so that clothes and the like can be prevented from being caught and the wheelchair 27 on which the movable treads 10A and 10B are ridden.
Even if the front wheel 27F is on a business trip to the specific step 5 side (FIG. 11),
There is no interference, and the wheelchair 27 can be stably transported. Further, even when the height of the footrest 28 of the wheelchair 27 is as low as the height of the footrest 28 'shown by the two-dot chain line in FIG. 11, interference can be avoided.

The specific steps 4, 5 are guide rails 9A, 9B.
When entering through the inclined section c of the convex piece sections d and horizontal section e upstairs floor side, as shown in FIG. 12, the movable tread plate 10B there H ₅ dimensions inclined section c step of special step 5 But,
Since almost no longer exists, the inclination maintaining arm 24 rises following the upper surface 4P of the base 4B of the specific step 4, and holds the inclined step board 17 horizontally. At this point, there is no step between the specific step 5 and the normal step 3 preceding it, and the step between the narrow step 11 of the specific step 4 and the narrow step of the specific step 5 is at the lower entrance. at a position almost the same as the H ₁ dimension at the stop position, the step sequence is stopped.

A power supply unit (not shown) such as a power supply plug connected to a power source is also located on the main frame 2 facing the drive unit 16 of the specific step 4 that has stopped. At this time, specific steps 4
The movable treads 10A and 10B are kept raised, and in this state, the wheelchair is pushed and carried out to the floor 1P on the upper floor.

When the removal of the wheelchair is completed, a staff member or a user of the wheelchair gives a command to end the wheelchair transfer operation or a command to return to the normal operation by operating a button. When this command is issued, the power supply unit automatically moves toward the terminal of the driving device 16 and connects. By this connection of the power source, the driving device 21 of the specific step 5 shown in FIG.
Is engaged with an engagement hole 18H provided in the inner wall 18W of the narrow tread plate 18 to maintain the inclined tread plate 17 horizontal. At the same time, the inclination maintaining arm 24 is retracted to release the engagement with the specific step 4.
After the inclination maintaining arm 24 is retracted from the base 4B of the specific step 4 or during the retraction, the driving device 16 of the specific step 4
Are driven in the opposite direction, the movable treads 10A and 10C are rotated by 180 degrees on the movable tread 10B and folded, and then the ascending mechanism 12 is driven in the descending direction so that the folded tread-extended tread 10 is fixed to the base 4B. Store in the position.

When it is confirmed by the detection mechanism such as a detection switch that the specific steps 4, 5 have returned to the original state, the steps are driven to return to the normal operation.

The above operation is performed from the lower floor 1D to the upper floor 1U.
In a wheelchair transfer operation toward the upper floor 1
When a wheelchair transfer operation is performed from U to the lower floor 1D, the operation is performed in a reverse manner to the above.

That is, when there is a wheelchair transfer operation command, the specific steps 4, 5 are moved to the positions shown in FIG.
0C is stopped in a state of being folded on the movable tread 10B, and when the stop is confirmed, the tread expanding tread 10 is lifted from the base 4B, and the movable treads 10A and 10C are moved to the movable tread 1.
The wheelchair mounting surface is formed by rotating by 180 degrees with respect to 0B. Then, get in the wheelchair and restart.

When the specific steps 4, 5 reach a predetermined position on the lower floor 1D side, they stop in the state shown in FIG. 4, and when the wheelchair 27 is lowered and a return command is given, the movable steps 10A, 10
B and 10C are folded from the state shown by the dashed line in FIG. 3, and after detecting that, the step train is driven to return to the normal operation.

As described above, according to this embodiment,
