Description
- The present invention relates to a passenger conveyor such as an escalator, an electrically operated road and the like, and more particularly to a passenger conveyor which is preferably placed in a narrow place.
- In conventional, in order to make a width of a passenger conveyor narrow, there have been already proposed a structure in which an electric motor is placed around a drive shaft for driving stairs and the drive shaft is directly driven (for example,
JP-A-56-108683 JP-A-55-40185 - On the other hand, in order to prevent a baggage of the passenger from hitting a balustrade panel, there has been proposed a technique in which a width of a passenger conveyor is enlarged by appearance by making an interval between right and left balustrade panels wider than an interval between right and left moving handrails, for example, in
JP-A-2001-139273 - The former of the prior arts mentioned above has an advantage that the width can be made narrower at a degree by which extra drive chain and drive sprocket for power transmission can be omitted by directly driving the stairs and the stairs chain by the electric motor.
- Further, the latter of the prior arts can make the passenger to get on the passenger conveyor on the safe side in a point that it is possible to reduce a change that the baggage of the passenger hits the balustrade panel.
- However, since the former of the prior arts mentioned above does not take into consideration a structure achieving a requirement of further width reduction, it is actually impossible to reduce the width more.
- Further, in the latter of the prior arts, since a sharp step is formed at a degree of difference between the balustrade panel interval and the moving handrail interval which becomes narrower than the balustrade panel interval which is expanded in an entrance portion of the passenger conveyor, the baggage hits the step portion such as a back side of a member guiding the moving handrail or the like, and there is a problem that an overturning trouble of the passenger is brought about.
-
JP-A-2001 139 273 Claim 1. Another related passenger conveyor is disclosed inUS-A-5 135 097 . - An object of the present invention is to provide a passenger conveyor which can sufficiently reduce a width.
- Another object of the present invention is to provide a passenger conveyor on which a passenger can get with slowing down even in the case that a width is reduced, and a baggage or the like can be prevented from hitting a back side of a member for guiding a moving handrail at a time of getting off.
- The present invention is defined in
Claim 1. Further advantageous features are set out in the dependent claims. - In order to achieve the objects mentioned above, in accordance with the present invention, a teeth portion of a drive sprocket which is coaxially provided in a main sprocket winding a stairs chain for connecting a plurality of step boards, and right and left side frames constituting a main frame are overlapped in a vertical projection.
- Further, an interval between opposing inner surfaces of balustrades provided in a rising manner in both sides of the stairs in a moving direction is formed wider than an interval between the moving handrails, and the expanded inner surface interval is formed so as to get close to the moving handrail interval step by step in a terminal end portion of the balustrade in a longitudinal direction.
- In other words, since the teeth portion of the drive sprocket and the side frames of the main frame are arranged so as to be overlapped in the vertical projection, it is possible to do away with a gap existing between the teeth portion of the drive sprocket and the side frames, and it is possible to get the side frames close to the drive sprocket at that degree, so that it is possible to reduce a width of the main frame.
- Further, since the baggage or the like of the passenger is not in contact with the balustrade by making the interval between the right and left balustrade inner surfaces wider than the interval between the moving handrails, the passenger can get on the conveyor with slowing down. Further, since the expanded inner surface interval is formed so as to get close to the moving handrail interval step by step in the terminal end portion of the balustrade in the longitudinal direction, the baggage or the like does not hit the back side or the like of the member guiding the moving handrail at a time when the passenger get off.

Further, the recess portion provided in the balustrade in the portion surrounded by the moving handrail described inclaim 2 is a recess portion formed by theinner surface portion 31, theperipheral edge portion 29 and thebase portion 30. Further, the interval of the balustrade panel described inclaim 3 is an interval between the right andleft balustrade panels 24, the expanded balustrade panel interval is an interval W1 between the right and leftinner surface portions 31, and the interval of the moving handrail is an interval W2 between the right and left movinghandrails 21. - On the other hand, in the
drive shaft 15 fixing a pair ofmain sprockets 13, adrive sprocket 33 is fixed to an opposite stair side of onemain sprocket 13. Thedrive sprocket 33 is formed in a dish shape expanding toward thebearing 16, and a teeth portion formed in an outer periphery is formed such that the teeth portion of the drive sprocket 33 and theside frame 5A overlap seen from a flat face while facing into the width h of theside frame 5A in themain frame 4, in other words, the teeth portion of thedrive sprocket 33 and theside frame 5A are arranged such that vertical projections thereof lap over each other. Accordingly, three elements comprising the teeth portion of thedrive sprocket 33, thebearing 16 and theside frame 5A of themain frame 4 are positioned within the width h of theside frame 5A such that the vertical projections thereof overlap each other. - A
power transmission chain 34 is wound around the teeth portion of thedrive sprocket 33, and thepower transmission chain 34 is wound around asprocket 36 of adriving machine apparatus 35 placed within the upperhorizontal portion 10 of themain frame 4 corresponding to an outer side of a reciprocating passage of thestairs 18. Thedriving machine apparatus 35 is constituted by anelectric motor 37, areduction gear 38, abrake 39 and the like, however, thereduction gear 39 is not necessarily required. - A
handrail drive sprocket 40 is fixed to an opposite side to the stair in each of a pair ofmain sprockets 13, and ahandrail drive chain 41 is wound around thehandrail drive sprocket 40 as shown inFig. 4 . Thehandrail drive chain 41 is structured such as to drive a handrail drive apparatus 43 (Fig. 2 ) via a turningroller 42. Thehandrail drive apparatus 43 is structured such as to drive a return side of the movinghandrail 21 in an inner side of thebalustrade 20 by a well-known means. - Since the structure is made such as mentioned above, it is possible to omit the space which is required because the teeth portion of the
drive sprocket 33 has been actually positioned between the bearing 16 and thehandrail drive sprocket 40, and the similar space which is required between themain sprocket 13 in the side having nodrive sprocket 33 and thebearing 16 taking into consideration the installation balance of themain frame 4 and thebalustrade 20, so that it is possible to reduce the total width of themain frame 4, and it is possible to make an installation width Wo of theescalator 1 narrow. - Further, since the
drive mechanism apparatus 35 is placed in an outer side in the longitudinal direction from a moving locus in a turning portion of thestairs 18, a maintenance and inspection space is not blocked by the stairs in comparison with the structure in which the driving machine apparatus is attached to a periphery of thedrive shaft 15, and it is possible to easily maintain and inspect the drivingmachine apparatus 35. - In the case of placing the
narrow escalator 1 having the structure mentioned above in a narrow place of an architectural structure, for example, the existing stairs of a station house or the like, theescalator 1 is normally placed close to one wall W in a width direction of the stairs S, as shown inFig. 1 , and thebalustrade 20 in an opposite side of theescalator 1 to the wall W is formed as a partition wall between the stairs S and theescalator 1. In the case of placing theescalator 1 having the installation width Wo in the stairs S as mentioned above, the width of the stairs S utilized by the passenger becomes narrow, however, since the installation width Wo of theescalator 1 is narrow as mentioned above, it is possible to reduce the used width of the stairs S to the minimum. - Further, since the recess portion is actually formed by denting the
balustrade panel 24 arranged vertically at the positions of theperipheral edge portion 29 and thebase portion 30 to the outer direction of theescalator 1, an occasion that the baggage is in contact with thebalustrade panel 24 is reduced even if the passenger gets on the escalator while directing the baggage to thebalustrade panel 24, so that the passenger can gets on the escalator with slowing down. - In addition, in the terminal end portion in the longitudinal direction of the
balustrade panel 24, since theslope portion 32A is formed in thebalustrade panel 24 formed in the recess portion, and is inclined at the slope angle by which the slope extension of theslope portion 32A does not cross thehandrail frame 23, the passenger reaches the getting-off port in a state in which the passenger makes the baggage to face to the recess portion of thebalustrade panel 24. Accordingly, even if the passenger is going to get off the escalator in this state, the baggage is guided to the stairs side along theslope portion 32A, so that the baggage does not come into collision with the back side of thehandrail 23 corresponding to the member for guiding the movinghandrail 21, and it is possible to prevent the overturning trouble due to the baggage collision. -
Fig. 7 shows the other embodiment which is an example useful to understand the present invention and which is largely different from the embodiment mentioned above in the structure of the balustrade, and has the same structures as those of the embodiment mentioned above in the structure of the main frame, the stairs and the drive mechanism of the moving handrail. - In this case, a
balustrade 60 in this embodiment is constituted by abalustrade panel 61 which is vertically fixed to theside frame 5A via a fixingdevice 62, ahandrail frame 23 which is fixed to a peripheral edge of thebalustrade panel 61 via a fixingdevice 63 and guides the movinghandrail 21, a coveringbody 64 which is fixed to the fixingdevice 63 in the peripheral edge of thebalustrade panel 61 and covers a lower portion of the fixingdevice 63, aninner deck cover 65 which covers a base portion of thebalustrade panel 61 and an upper portion in a side of the fixingdevice 62, theskirt guard 27 which sections between theinner deck cover 65 and thestairs 18, and theouter deck cover 25 which is placed between thehandrail frame 23 and the peripheral edge of thebalustrade panel 61. - The
balustrade panel 61 is formed, for example, by a reinforced glass plate, a reinforced synthetic resin plate or the like, and has the same function serving as a design product as that of the outward packing product in the embodiment mentioned above. Further, the coveringbody 64 is placed at a slant with respect to thebalustrade panel 61, and the slope is set more gentle that the slope of the coveringbody 64 placed so as to oppose to the stairs moving section, such that a direction of the baggage of the passenger is not rapidly changed in the terminal end portion in the longitudinal direction of the balustrade. - In accordance with the
balustrade 60 having the structure mentioned above, since thesupport column 22, thebalustrade panel 24 and theoutward packing plate 28 in the embodiment mentioned above are structured by onebalustrade panel 61, it is possible to further expand an interval W3 between a pair of opposingbalustrade panels 61 in comparison with the interval W1 between thebalustrade panels 24 in accordance with the embodiment mentioned above. - In addition, it is possible to have a balustrade lighting equipment built-in by utilizing a
space 66 which is formed between an upper end (a peripheral edge) of thebalustrade panel 61 and thehandrail 23 by the coveringbody 64, whereby it is possible to provide thebalustrade 60 with light. Further, an operation switch may be provided in a terminal end portion in a balustrade longitudinal direction of the coveringbody 64, in the same manner as that of the embodiment. - In accordance with the embodiment having the structure mentioned above, it is possible to further expand the
balustrade panel 61, and it is possible to achieve the same operations and effects as those of the embodiment mentioned above. - In this case, the embodiment mentioned above is described on the basis of the escalator which is exemplified as the passenger conveyor. However, it goes without saying that the present invention can be applied to an electrically operated road in which no step is generated between the step plates. In this case, the structure of the embodiments mentioned above and claims can be applied by replacing the stairs described in the embodiments mentioned above and claims by the step plate.
- As mentioned above, in accordance with the present invention, it is possible to obtain the passenger conveyor which can sufficiently reduce the width, and it is possible to obtain the passenger conveyor which the passenger can get on even in the case that the width is reduced, and the baggage does not come into collision with the member for guiding the moving handrail at a time when the passenger gets off.
