Abstract

A passenger conveyor that can be sufficiently reduced in the width dimension of a main frame, of course, and allows passengers to ride on with sufficient room despite the reduction in the width dimension of the main frame, eliminating the possibility of the baggage or the like hitting the railings when passengers get off. To this end, the passenger conveyor is so constructed that the teeth of main sprocket and a drive sprocket coaxial therewith having a treadboard chain entrained therearound overlaps a side frame, as seen in their vertical projective figures, the side frame constituting the main frame, and that the inner surface spacing between the right and left railings is greater than that of the moving handrails and in the longitudinal terminal ends of the railings the inner surface spacing made greater gradually approaches the spacing of the moving handrails.

Description

Specification

Passenger conveyor technology

TECHNICAL FIELD The present invention relates to a passenger conveyor such as an S-power train or an electric road, and more particularly to a passenger conveyor suitable for being installed in a narrow area. Background art

Conventionally, in order to reduce the width of the passenger conveyor, a configuration in which an electric motor is installed around the drive shaft for driving the steps and the drive shaft is directly driven (for example, JP-A-56-108683), In the meantime, a configuration for directly driving a step drive chain (for example, Japanese Patent Application Laid-Open No. 55-40185) has been proposed.

On the other hand, in order to avoid the passenger's baggage from hitting the balustrade panel, a technique of increasing the space between the left and right balustrade panels than the space between the left and right handrails and apparently widening the passenger contest, for example, is disclosed in 2001- 1 in 39,273 No. Publication been proposed of ^1.

The former of the above prior art has the advantage of being able to reduce the width dimension by directly driving a step or a step chain with an electric motor, so that an extra drive chain and a drive sprocket for power transmission can be omitted.

In addition, the latter of the prior art is able to get on the passenger conveyor with plenty of margin in that it reduces the chance of the passenger's baggage hitting the balustrade panel.

However, in the former of the above-mentioned conventional techniques, no consideration is given to the case where further reduction in the width dimension is required, and further reduction in the width direction has been practically difficult. Furthermore, in the latter case of the prior art, a steep step is formed at the getting-on / off portion of the passenger conveyor, which is equal to the moving handrail interval narrower than the widened balustrade panel interval. There is a problem that a collision occurs at a stepped part such as the back side of a member that guides passengers, causing passengers to fall. Disclosure of the invention

An object of the present invention is to provide a passenger contest capable of sufficiently reducing the width dimension.

Another object of the present invention is to provide a passenger who can comfortably ride even if the width dimension is reduced and that the baggage or the like does not collide with the back side of the member guiding the moving hand when getting off. To provide a conveyor.

In order to achieve the above object, the present invention provides a main sprocket for winding a step chain connecting a plurality of treads and a tooth portion of a drive sprocket coaxial with a main sprocket and left and right side frames constituting a main frame. They were arranged so that the vertical projections overlap.

Further, the interval between the facing inner surfaces of the balustrades erected on both sides in the moving direction of the steps is formed wider than the interval between the moving handrails, and at the longitudinal end portion of the balustrade, the widened inner surface interval is gradually decreased. It was formed so as to approach the distance between the moving handrails.

In other words, by disposing the teeth of the drive sprocket and the side frames of the main frame so that their vertical projections overlap each other, the gap existing between the teeth of the drive sprocket and the side frames is reduced. Therefore, the side frame can be moved closer to the drive sprocket side, and as a result, the width of the main frame can be reduced.

In addition, the distance between the inner surfaces of the left and right balustrades was made wider than the distance between the moving handrails. Therefore, since the baggage of the passenger does not come into contact with the balustrade, the passenger can ride with ease, and at the longitudinal end portion of the balustrade, the width of the widened inner surface is gradually reduced. By forming the moving handrail close to the space, the baggage and the like do not collide with the back side of the member including the moving handrail when the passenger gets off.

Hereinafter, a passenger conveyor according to an embodiment of the present invention will be described with reference to an escalator shown in FIGS. 1 to 6. Generally, the escalator 1 is constructed based on the main frame 4 installed on the upper floor 2 and lower floor 3 of the building. As shown in FIG. 3, the main frame 4 is composed of a pair of left and right side frames 5A and 5B, a bottom plate 6 and a horizontal girder 7 connecting the left and right side frames 5A and 5B. The side frames 5A and 5B connect the upper chord 8A, the lower chord 8B, and the upper chord 8A and the lower chord 8B extending in the longitudinal direction of the escalator. And a vertical member 9.

An upper horizontal section 10 serving as an upper machine room is formed on the upper floor 2 side of the main frame 4 having the above configuration, and a lower horizontal section 11 serving as a lower machine room is formed on the lower floor 3 side. An inclined portion 12 is connected between 10 and the lower horizontal portion 11. In general, the upper part of the upper horizontal part 10 and the upper part of the lower horizontal part 11 are closed by the floors 1 OF and 11F, respectively, for passengers to get on and off.

Below the upper and lower floors 10F and 1IF of the upper horizontal section 10 and lower horizontal section 11 of the main frame 4 constructed in this way, a pair of main sprockets 13 and sub-sprockets 1 are respectively provided. 4 and are pivoted. A pair of main sprockets 13 are fixed to a drive shaft 15, and both ends of the drive shaft 15 are rotatably held by bearings 16. The bearing 16 is fixed to the vertical member 9 of the side frames 5A, 5B, and its vertical projection is within the width h of the side frames 5A, 5B.

An endless step chain 17 is wound around the main sprocket 13 and the slave sprocket 14, and a step 18 is connected to the step chain 17. The step 18 has a front wheel 19A and a rear wheel 19B running on guide rails laid in the main frame 4. The front wheel 19A is rotatably supported by a front wheel axle projecting in the width direction of the step 17. By connecting the front wheel axle to the step chain 17, a large number of steps 18 are formed. It is connected to the step chain 17.

A balustrade 20 is erected on each of the side frames 5A and 5B, and a moving handrail 21 is guided on the periphery of the balustrade 20. The balustrade 20 is composed of a support 22 standing upright on the upper chord 8A of the side frames 5A and 5B, a handrail frame 23 supported on the upper end of the support 22, and a handrail frame 2 3 The upper end of the support 22 is supported by the upper end of the support 22, and the lower end is supported by the lower end of the support 22. Cover a lower portion of the inner deck cover 26, a skirt guard 27 partitioning between the inner deck cover 26 and the steps 18 and an outer cover provided outside the handrail frame 23. The deck cover 25 is provided.

As shown in Fig. 1 and Fig. 3, if Escalée 1 is located close to the wall W of the building and the stairs S are installed on the opposite side of the wall W, Outside the balustrade 20 on the side of the stairs S, an exterior panel 28 for makeup is provided vertically from the outer deck cover 25, and the balustrade 20 on the wall W side brings the handrail frame 23 closer to the wall W, By closing the gap with the outer deck cover 25, the construction of the outer panel 28 is omitted.

The balustrade panel 24 of the balustrade 20 configured in this way has a peripheral edge 29 facing the end inside the handrail frame 23 and an edge facing the inside deck cover 26. Base portion 30, an inner surface portion 31 having a height H which is located on a side opposite to the step and is occupying most of the vertical height with respect to the peripheral portion 29 and the base portion 30, an inner surface portion 31 and the peripheral portion 29 and between the base 30 and the inclined portions 32 A and 32 B formed at an angle 01 of 90 degrees or more with respect to the inner surface 31, and the inner surface 31 1 as a whole. , A peripheral portion 29 and a base portion 30 form a concave portion that opens to the step 18 side. The recess having the inner surface 31 with a height H is formed over substantially the entire length of the balustrade 20, and guides the passenger's baggage to the step side as shown by arrows B and C in FIG. It is formed so as to continue to the peripheral portion 29 via the inclined portion 32A at the end portion in the longitudinal direction of 12,000. Further, the recess is widened by a width Wa on one side of the center A of the moving handrail 21, and the width Wa is configured to contribute to the widening above the feet of the passenger. The concave portion is a linear concave portion formed by the peripheral portion 2.9, the base portion 30 and the inner surface portion 31. As shown by a two-dot chain line D in FIG. It may be formed to have a curved surface. It is desirable that the inclined portion 32A between the peripheral edge portion 29 and the inner surface portion 31 of the drying panel 24 has an inclined angle such that the extension of the inclined line does not intersect the handrail frame 23. In addition, the inclined portion 32B between the base portion 30 and the inner surface portion 31 has an inclined angle such that the extension of the inclined line does not intersect the inner deck cover 26. The inclination angle Θ 2 (FIG. 6) of the inclined portion 32 A at the longitudinal end of the balustrade 20 is formed in the recess of the panel 24 by forming the inclination angle Θ 2 (FIG. 6) larger than the angle. As shown by arrow E, the passenger's baggage can be guided smoothly. 'In this case, it is not essential that the extension line of the inclined section 32A does not intersect with the handrail frame 23.If there is no large step with the handrail frame 23, the inclined extension of the inclined section 32A is extended. There is no problem if the line intersects with step frame 23.

In addition, an operation switch 50 such as a start switch and a stop switch of the escalator 1 is provided on an inclined portion 32A in FIG. 6 which is a terminal inclined surface of a longitudinal end portion of the balustrade panel 24. On the back side, a switch box 51 is attached. Thus, by providing the operation switch 50 on the end inclined surface of the longitudinal end portion of the balustrade panel 24, the operation position becomes higher than before, so that the operability is conspicuous and easy to operate. Has the effect of improving the function.

Here, the inner surface portion 31 is a surface separated from the moving handrail of the balustrade according to claim 1, and the inclined portion 32A is a surface approaching the moving handrail. Further, the concave portion provided on the balustrade at a portion surrounded by the moving handrail according to claim 2 is a concave portion formed by the inner surface portion 31, the peripheral edge portion 29, and the base portion 30. In addition, the spacing between the balustrade panels described in claim 3 is the spacing between the left and right balustrade panels 24 and the widened balustrade panel spacing is the spacing W i between the left and right inner surface parts 31, The distance between the moving handrails is the distance W2 between the left and right moving handrails 2 1 is there.

On the other hand, the drive shaft 15 for fixing the pair of main sprockets 13 has the drive sprocket 33 fixed to the other step side of the one main sprocket 13. The drive sprocket 33 is formed in a dish shape spreading toward the bearing 16, and the teeth formed on the outer periphery are viewed from a flat surface facing the width h of the side frame 5 A of the main frame 4. In this case, the teeth of the drive sprocket 33 and the side frame 5A are overlapped, in other words, the teeth of the drive sprocket 33 and the side frame 5A are arranged so as to overlap each other vertically. Have been. Therefore, the tooth projections of the drive sprocket 33, the bearing 16 and the side frame 5A of the main frame 4 also overlap each other in the vertical projection, and are within the width h of the side frame 5A. Will be located. A power transmission chain 34 is wound around the teeth of the drive sprocket 33, and the power transmission chain 34 is attached to the upper horizontal portion 1 of the main frame 4 outside the reciprocating passage of the step 18. It is wound around the bracket 36 of the drive mechanical device 35 installed in 0. The drive mechanical device 35 includes an electric motor 37, a speed reducer 38, a brake 39, and the like, but the speed reducer 39 is not always required.

Further, a handrail drive sprocket 40 is fixed to the counter step side of the pair of main sprockets 13, respectively, and the handrail drive sprocket 40 has a handrail drive chain 4 as shown in FIG. One is wound. The handrail drive chain 41 drives a handrail drive device 43 (FIG. 2) via a turning roller 42. This handrail drive device 43 drives the return side of the moving handrail 21 inside the balustrade 20 by a known means. Since the above configuration is adopted, the drive sprocket 33 Considering the space required due to the teeth being located between the bearing 16 and the handrail drive sprocket 40, and the installation balance of the main frame 4 and balustrade 20 As a result, the same space that was required between the main sprocket 13 and the bearing 16 on the side where the drive sprocket 33 is not provided can be eliminated, and as a result, the entire width of the main frame 4 can be reduced. It is possible to reduce the installation width dimension Wo of Escalée 1.

In addition, since the driving mechanical device 35 is installed in the longitudinal direction outside the movement locus of the step 18 in the direction changing portion, the driving mechanical device 35 is compared with a configuration in which the driving mechanical device is mounted around the driving shaft 15. The maintenance step is not obstructed by the steps, and the maintenance of the drive mechanical device 35 can be easily performed.

When the narrow escalator 1 having the above configuration is installed in a narrow area of a building, for example, on an existing staircase of a station building, as shown in Fig. 1, the wall W on one side in the width direction of the staircase S is usually used. A railroad railing 20 on the opposite side of W from the side of Escalée 1 has been set up as a partition wall between stairs S and escalator 1. In this way, when the installation width dimension W o is installed on the stairs S, the width used for pedestrians on the stairs S is reduced. Since “0” is narrow as described above, it is possible to minimize the required width of the stairs S to a minimum.

Furthermore, since the balustrade panel 24, which is normally arranged at the position of the peripheral part 29 and the base part 30, is depressed outwardly of the Escalée 1 to form a recess, passengers can carry luggage. Even if the passenger is riding toward the balustrade panel 24, the chance of baggage contacting the balustrade panel 24 is reduced, and passengers can ride comfortably.

In addition, an inclined portion 32A is formed in the balustrade panel 24 formed in the recess at the longitudinal end of the drying panel 24, and the handrail frame 23 is formed on the inclined extension line of the inclined portion 32A. Because it is inclined at an inclination angle that does not intersect with the passenger Arrives at the exit with the baggage facing the recess of the balustrade panel 24, and even if the user tries to get down in that state, the baggage is guided to the step side along the inclined portion 32A. Therefore, the baggage does not collide with the back side of the handrail frame 23, which is a member for guiding the moving handrail 21, and it is possible to eliminate a fall accident due to the baggage collision.

FIG. 7 shows another embodiment according to the present invention. What is greatly different from the above embodiment is the balustrade structure, and the main frame structure, the steps and the drive mechanism of the moving handrail are the same as those in the above embodiment. Is the same as

That is, the balustrade 60 according to this embodiment includes a balustrade panel 61 fixed vertically to the side frame 5A via the fixing tool 62, and a balustrade panel 63 at the periphery of the balustrade panel 61 via the fixing tool 63. A handrail frame 2 3 that is fixed and guides the moving handrail 2 1, a cover 6 4 that is fixed to the fixing tool 6 3 around the balustrade panel 6 1 and covers the lower part of the fixing tool 6 3, 6 An inner deck cover 65 covering the base of 1 and the upper part of the fixture 6 2 side, a force guard 27 separating the inner deck cover 65 and the steps 18 and the handrail frame 23 An outer deck cover 25 is installed between the peripheries of the drying panels 61.

The balustrade panel 61 is formed of, for example, a reinforced glass plate, a reinforced synthetic resin plate, or the like, and has a function as a design product similar to the exterior plate 28 of the embodiment. In addition, the covering 64 is installed at an angle to the balustrade panel 61, and the inclination is opposed to the step moving section so that the passenger's baggage is not suddenly changed in the longitudinal end of the balustrade. The slope is gentler than the slope of the covering 64 that is installed.

According to the balustrade 60 having the above-described configuration, since the columns 22, the balustrade panels 24, and the exterior panel 28 as in the above-described embodiment are constituted by one balustrade panel 61, a pair of facing balustrades is provided. The interval W3 of the panel 61 is set to the balustrade The width can be wider than the interval W i of the flannel 24.

In addition, a balustrade lighting device can be built in by using a space 66 formed between the upper end (peripheral edge) of the balustrade panel 61 and the hand frame 23 by the covering body 64. Then we can provide 60 illuminated balustrades. Further, an operation switch may be provided at the end of the balustrade in the longitudinal direction of the balustrade, similarly to the above embodiment.

According to the embodiment having the above-described configuration, the width of the balustrade panel 61 can be further increased, and the same operation and effect as in the above-described embodiment can be obtained. By the way, the above-described embodiment has been described by way of example of Escalei Yuichi as a passenger conveyor. However, it is needless to say that the present invention can also be applied to an electric road that does not generate a step between treads. This can be dealt with by reading the steps described in the description and claims as footboards.

As described above, according to the present invention, it is possible not only to obtain a passenger conveyor capable of sufficiently reducing the width dimension, but also to allow the passenger to get on with ease even if the width dimension is reduced, and to get off. It is possible to obtain a passenger conveyor in which baggage or the like does not sometimes collide with a member for guiding the moving handrail.
