2. Description of the Related Art In recent years, many escalators with a high head have been installed in subway stations and the like. In this type of escalator, many passengers feel uncomfortable because they have to stand on the steps for a long time. For this reason, an escalator that operates at a high speed has been developed, but the operating speed has an upper limit value for passengers to get on and off safely.

On the other hand, with respect to the moving speeds of the steps at the upper and lower entrance portions where passengers get on and off,
There has been proposed a high-speed inclined escalator capable of shortening the time spent on an escalator by operating a relatively high step moving speed at an intermediate inclined portion. Such a high-speed inclined portion escalator is disclosed in, for example, Japanese Patent Laid-Open No. 51-116586.

FIG. 5 is a schematic side view showing an example of a conventional inclined portion high speed escalator. In the figure, a main frame 1 is provided with a plurality of steps 2 connected endlessly. The steps 2 are driven by the drive unit 3 and are circulated. In the main frame 1, a pair of drive roller rails 4 forming a circulation path of the steps 2, a pair of follower roller rails 5 for controlling the posture of the steps 2, and a space between the adjacent steps 2 are changed. A pair of auxiliary roller rails 6 are provided.

The circulation path of the step 2 formed by the drive roller rail 4 has a forward path section, a return path section, an upper reversal section F and a lower reversal section I. Further, in the outward path section of the circulation path, a horizontal upper entrance / exit portion (upper horizontal portion) A, an upper curved portion B, an intermediate inclined portion (constant inclined portion) C having a constant inclination angle,
It includes a lower curved portion D, a horizontal lower entrance / exit portion (lower horizontal portion) E, an upper transition portion G, and a lower transition portion H.

The intermediate inclined portion C is located between the upper side entrance / exit section A and the lower side entrance / exit section E. The upper curved portion B is located between the upper entrance / exit portion A and the intermediate inclined portion C. Lower bend D
Is located between the lower entrance / exit portion E and the intermediate inclined portion C. The upper transition portion G is located between the upper entrance / exit portion A and the upper reversal portion F. The lower transition section H is the lower entrance / exit section E.
And the lower reversal portion I.

A pair of boarding plates 22a and 22b are arranged above the steps 2 of the upper entrance A and the lower entrance E. The boarding boards 22a, 22b are arranged on the floors of the upper boarding section A and the lower boarding section E so as to cover the steps 2. On the upper part of the main frame 1, a pair of moving handrail devices 23 are provided upright. The moving handrail devices 23 are arranged on both sides of the step 2 in the width direction.

FIG. 6 is a side view showing the vicinity of the upper entrance / exit portion A of FIG. Each step 2 has a tread 7, a tread 7 on which passengers can be placed.
A riser bent at the lower end of the drive roller, a drive roller shaft 9, a pair of drive rollers rotatable about the drive roller shaft 9, a follower roller shaft 11, and a follower roller shaft 11
It has a pair of follow-up rollers 12 which are rotatable around. The drive roller 10 rolls along the drive roller rail 4. The follower roller 12 is the follower roller rail 5
Roll along.

Drive roller shafts 9 of steps 2 adjacent to each other
Are connected to each other by a pair of link mechanisms (refractive links) 13. Each link mechanism 13 includes the first to fifth
Links 14 to 18 are included.

One end of the first link 14 is rotatably connected to the drive roller shaft 9. The other end of the first link 14 is rotatably connected to an intermediate portion of the third link 16 via a shaft 19. One end of the second link 15 is rotatably connected to the drive roller shaft 9 of the adjacent step 2. The other end of the second link 15 is rotatably connected to an intermediate portion of the third link 16 via a shaft 19.

One end of the fourth link 17 is rotatably connected to the intermediate portion of the first link 14. One end of the fifth link 18 is rotatably connected to the intermediate portion of the second link 15. 4th and 5th link 1
The other ends of the 7, 18 are connected to one end of the third link 16 via the sliding shaft 20.

A guide groove 16a for guiding sliding of the sliding shaft 20 in the longitudinal direction of the third link 16 is provided at one end of the third link 16. A rotatable auxiliary roller 21 is provided at the other end of the third link 16.
The auxiliary roller 21 is guided by the auxiliary roller rail 6.

When the auxiliary roller 21 is guided by the auxiliary roller rail 6, the link mechanism 13 is transformed so as to bend and expand, and the space between the drive roller shafts 9, that is, the adjacent steps 2
The mutual spacing is changed. Conversely speaking, the adjacent steps 2
The track of the auxiliary roller rail 7 is designed so that the mutual distance changes.

Next, the operation will be described. The speed of the steps 2 is changed by changing the distance between the drive roller shafts 9 of the adjacent steps 2. That is, the interval between the drive roller shafts 9 is larger in the intermediate inclined portion C than in the upper entrance / exit section A and the lower entrance / exit section E where passengers get on and off. As a result, the step 2 is moved at a higher speed at the intermediate inclined portion C than at the upper side entrance / exit section A and the lower side entrance / exit section E.

First, second, fourth and fifth links 14,
Reference numerals 15, 17, and 18 constitute a so-called pantograph-type four-link mechanism, and increase or decrease the angle formed by the first and second links 14 and 15 with the third link 16 as the axis of symmetry. be able to. As a result, the distance between the drive roller shafts 9 connected to the first and second links 14 and 15 can be changed.

That is, when the distance between the drive roller rail 4 and the auxiliary roller rail 6 is made small, the link mechanism 13 operates in the same manner as the operation of the frame of the umbrella when the rain umbrella is spread, and the adjacent steps 2 of the step 2 are operated. The distance between the drive roller shafts 9 becomes large.

In the intermediate inclined portion C of FIG. 5, the distance between the drive roller rail 4 and the auxiliary roller rail 6 is minimized, and the distance between the drive roller shafts 9 of the adjacent steps 2 is maximized. Therefore, the speed of the step 2 becomes maximum. In this state, the first and second links 14 and 15 are arranged on a substantially straight line.

Further, in the inclined portion high speed escalator in which the gap between the steps 2 is widened at the intermediate inclined portion C, the riser 8 has a shape protruding toward the lower step side in order to fill the opening between the adjacent step plates 7. Step 2 having riser 8 having such a shape
If the steps 2 are inverted by the inversion parts F and I, the steps 2 interfere with each other unless the interval between the steps 2 is widened. Therefore, in the reversing portions F and I, the interval between the steps 2 is widened. Therefore, in the transition parts G and H, the operation of extending the link mechanism 13 is performed.

[0019]

However, in the conventional high-speed inclined portion escalator constructed as described above, a large number of bearing portions must be provided in the link mechanism 13, and due to manufacturing errors and wear of the bearing portions. The influence of backlash generated becomes large, the interval between the drive roller shafts 9 becomes too large,
On the contrary, the adjacent steps 2 may interfere with each other.

Further, in the conventional high-speed inclined portion escalator, the third link 16 projects above the height of the boarding / alighting plates 22a and 22b when the link mechanism 13 is extended at the transitional sections G and H. Therefore, in an area where the moving handrail device 23 is located directly above the link mechanism 13, the link mechanism 13 is
Can not perform the action of extending. Therefore, for example, as shown in FIG. 7, the gap between the steps 2 starts to be opened from a position where the steps 2 are considerably inside the end portions 22c of the boarding / alighting plates 22a and 22b. As a result, the lengths of the upper side entrance / exit section A and the lower side entrance / exit section E become long, and the escalator becomes large.

Further, in the conventional high-speed inclined portion escalator, the auxiliary roller rail 6 in the upper curved portion B and the lower curved portion D has a smooth arc shape. Therefore, the change in step between the steps 2 adjacent to each other is not completed in the upper curved portion B and the lower curved portion D, and the change in step continues in the upper side entrance / exit section A, the lower side entrance / exit section E, or the intermediate slope C. ing. Therefore, the cross-sectional shape of the riser 8 becomes a discontinuous shape bent in the inclination direction of the intermediate inclined portion C as shown in FIG.
It cannot be made into a continuous flat surface or curved surface, resulting in high manufacturing cost.

The present invention has been made to solve the above problems, and it is possible to reduce the number of bearing portions in a link mechanism and to simplify the structure of the link mechanism. An object of the present invention is to obtain a high-speed inclined portion escalator capable of reducing the error in the distance between the drive roller shafts due to error or wear.

Drive roller shaft 3 of steps 34 adjacent to each other
7 are connected to each other by a pair of link mechanisms (refractive links) 41. Each link mechanism 41 has a first and second link mechanism.
It has links 42 and 43.

One end of the first link 42 is rotatably connected to the drive roller shaft 37. First link 42
A rotatable auxiliary roller 44 is provided at the other end of the. The auxiliary roller 44 rolls along the auxiliary roller rail 33. One end of the second link 43 is rotatably connected to an intermediate portion of the first link 42 via a shaft 45. The other end of the second link 43 is rotatably connected to the drive roller shaft 37 of the step 34 adjacent to the lower step side.

The first link 42 includes a linear first portion 42a connected to the drive roller shaft 37 and the auxiliary roller 4.
4 is attached to the linear second portion 42b. In the middle of the first link 42, the second portion 42
b is fixed to the first portion 42a at a predetermined angle.
Therefore, the first link 42 is bent at the intermediate portion in the direction away from the second link 43 and has a dogleg shape. The first and second portions 42a and 42b may be integrated.

The auxiliary roller 44 is the auxiliary roller rail 33.
By being guided by, the link mechanism 41 is transformed so as to bend and stretch, and the distance between the drive roller shafts 37, that is, the distance between the adjacent steps 34 is changed. Conversely speaking, the track of the auxiliary roller rail 33 is designed so that the interval between the adjacent steps 34 changes.

FIG. 4 is an explanatory view showing the positional relationship between the boarding / alighting plates 22a, 22b and the steps 34 of the inclined portion high-speed escalator of FIG. Upper entrance / exit section A and lower entrance / exit section E
Then, immediately after the steps 34 are placed under the boarding plates 22a and 22b, the interval between the steps 34 adjacent to each other starts to widen, and immediately before the steps 34 come out from under the boarding plates 22a and 22b, the steps 34 adjacent to each other. Is configured to complete the reduction of the interval. That is, even in the section where the boarding / alighting plates 22a and 22b are located above the step 2 and the moving handrail device 23 is arranged, the interval between the steps 34 adjacent to each other is opened.

Next, the operation will be described. The adjacent steps 34 are connected to each other by a link mechanism 41, and the distance between the drive roller shafts 37 of the adjacent steps 34 is
It changes depending on the angle formed by the first and second links 42, 43. The angle formed by the first and second links 42 and 43 is determined by the drive roller rail 31 and the auxiliary roller rail 3
3 depending on the distance between them. At this time, the tread 3
The posture of No. 4 is appropriately maintained by the follower roller 39 being guided by the follower roller rail 52.

As shown in FIG. 1 and FIG. 2, at the upper entrance / exit A and the lower entrance E of the forward side section of the circulation path of the step 34, as shown in FIGS. Has been minimized. From this state, when the distance between the drive roller rail 31 and the auxiliary roller rail 33 becomes smaller, the angle formed by the first and second links 42 and 43 becomes larger, and the drive roller shaft 37 of the adjacent step 34 is formed. The intervals between will become larger.

At the intermediate inclined portion C, the drive roller rail 3 is provided.
The distance between 1 and the auxiliary roller rail 33 is minimum, and the distance between the drive roller shafts 37 of the adjacent steps 34 is maximum.

The speed of the steps 34 is changed by changing the distance between the drive roller shafts 37 of the adjacent steps 34. That is, in the upper and lower entrance / exit sections A and E where passengers get in and out, the above interval is minimized and the step 34 is moved at a low speed. Further, in the intermediate inclined portion C, the above interval becomes maximum, and the steps 34 are moved at high speed. In addition, in the first link 42 in this state, the first portion 42a and the second portion 42a
The links 43 and are arranged on a substantially straight line. Further, in the upper curved portion B and the lower curved portion D, the interval between the adjacent steps 34 is changed, and the steps 34 are accelerated / decelerated.

In such an inclined portion high speed escalator, two links, that is, the first and second links 42 and 4 are used.
Since the distance between the drive roller shafts 37 is changed by the link mechanism 41 having the number 3, the bearing portion in the link mechanism 41 is only required to be provided at one place of the connecting portion between the first link 42 and the second link 43. Therefore, the structure of the link mechanism 41 can be simplified, the influence of backlash caused by the error and wear of the bearing portion can be suppressed, and the error of the interval between the drive roller shafts 37 can be reduced. In addition, the link mechanism 41
By simplifying, the manufacturing cost is also reduced.

When a tensile force or a compressive force acts between the steps 34, the load is received by the auxiliary roller 44. The force supported by the auxiliary roller 44 is the first and the second.
In relation to the angle formed by the links 42 and 43, the auxiliary roller 44 has the first and second links 4 at the intermediate inclined portion where the first portion 42a and the second link 43 are aligned.
Only the weight of 2,43 is applied.

However, as the distance between the drive roller shafts 37 becomes smaller and the opening angle between the first and second links 42, 43 becomes smaller, the auxiliary roller 44 when the tension / compression force acts between the steps 34 becomes smaller. This force becomes large. When the tension / compression force acts between the steps 1 at the upper and lower entrance portions where the distance between the drive roller shafts 37 is minimum, the auxiliary roller 44 receives the largest force.

On the other hand, in this embodiment, at the upper and lower entrances and exits, the second portion 42b to which the auxiliary roller 44 is attached extends at a right angle to the auxiliary roller rail 33. Has been done. Therefore, the bending stress is not generated in the second portion 42b, and only the tensile / compressive stress is generated, and the mechanical load is significantly reduced. This ensures sufficient reliability.

Further, the bending stress generated in the second portion 42b is reduced by bending the second portion 42b with respect to the first portion 42a, and the second portion 42b with respect to the auxiliary roller rail 33. It becomes the minimum by making it a right angle.

Further, when the link mechanism 41 is used, the boarding boards 22a, 22a, 22a, 22a, 22a, 22a, 22a, 22a and 22b are widened even if the distance between the steps 34 is increased in the horizontal portion.
Since it does not project above b, the boarding boards 22a, 22b
Immediately after the step 34 is inserted under the
As the interval of 4 starts to spread, the boarding boards 22a, 22a
Immediately before the step 34 comes out from under the b, the interval between the steps 34 adjacent to each other can be reduced. That is, even in the region where the moving handrail device 23 is arranged above, the gap between the steps 34 adjacent to each other can be opened. Therefore, the length of the upper and lower entrance portions A and E can be suppressed to be small, and the escalator as a whole can be downsized.

Here, when the moving speed of the step 34 changes, the relative position of the step 34 adjacent to the lower step with respect to the step 34 changes. At this time, the end portion of the tread plate 35 of the step 34 adjacent to the lower step has the riser 3 of the step 34 on the upper step side.
6 along the surface. In the outward path section of this embodiment, the moving speed of the step 34 is changed only by the upper curved portion B and the lower curved portion D. Therefore, the relative positional change of the lower step plate 35 with respect to the upper riser 36 is also completed only in the section of the upper curved portion B and the lower curved portion D in the outward path section. Therefore, the shape of the riser 36 can be a continuous flat surface or a curved surface, and the manufacturing cost can be reduced.

A second link in which one end is rotatably connected to the intermediate part of the link and the other end is connected to the adjacent step in a state of being rotatable around the drive roller shaft of the adjacent step. Using a plurality of link mechanisms each of which has a rotatable auxiliary roller at the other end of the first link, by changing the distance between the drive roller guide rail and the auxiliary roller guide rail, Since the angle of the second link with respect to the first link is changed to change the distance between the drive roller shafts of the drive rollers of the steps adjacent to each other, the bearing portion in the link mechanism is reduced and the structure of the link mechanism is reduced. Simplify It is possible, it is possible to reduce the error in the distance between the drive roller shaft caused by errors or wear of the bearing unit.

The first part having a bent shape
Since this link is used, it is possible to reduce the bending stress generated in the first link when a load is applied to the auxiliary roller, and it is possible to improve the reliability. Further, the inclined portion high-speed escalator of the present invention is configured such that, when the distance between the drive roller shafts is the smallest, the portion from the bent portion of the first link to the other end extends at right angles to the auxiliary roller rail. Therefore, when a load is applied to the auxiliary roller,
The bending stress generated in the first link can be reduced more reliably, and the reliability can be further improved.

Furthermore, in the high-speed inclined escalator of the present invention, the space between the steps adjacent to each other begins to widen immediately after the steps are put under the boarding board at the upper entrance and the lower entrance. Since it is configured, it is possible to reduce the lengths of the upper and lower entrances and exits and to downsize the entire escalator. Further, the inclined portion high-speed escalator according to the present invention is configured such that, in the upper side entrance / exit section and the lower side entrance / exit section, the interval between the steps adjacent to each other is completed immediately before the steps exit from the bottom of the boarding / alighting board. Therefore, the lengths of the upper and lower entrances and exits can be suppressed to be small, and the entire escalator can be downsized.

Furthermore, in the high-speed inclined escalator according to the present invention, the moving speed of the steps is changed only by the upper and lower curved portions in the outward path section, so that the shape of the riser is a continuous plane or curved surface. Therefore, the manufacturing cost can be reduced.
