  The frame 4 is installed across the lower floor 100A and the upper floor 100B. The frame 4 is constituted by a truss structure having a lower frame, an upper frame facing the lower frame, and a vertical frame connecting the lower frame and the upper frame.

  The frame 4 has a lower floor horizontal portion 4a, an upper floor horizontal portion 4b, and an intermediate inclined portion 4c. The lower floor horizontal portion 4a and the upper floor horizontal portion 4b are formed in parallel to each other. The lower floor horizontal portion 4a and the upper floor horizontal portion 4b are portions that are kept parallel to the upper floor 100B and the lower floor 100A in a state where the frame 4 is installed in the building structure 100. .

  The intermediate inclined portion 4c is provided between the lower floor horizontal portion 4a and the upper floor horizontal portion 4b. The middle inclined portion 4c is inclined with respect to the lower floor horizontal portion 4a and the upper floor horizontal portion 4b. Hereinafter, the direction in which the frame 4 extends from the lower floor 100 </ b> A toward the upper floor 100 </ b> B is the longitudinal direction of the frame 4. In addition, the direction perpendicular to the longitudinal direction and the vertical direction of the frame 4, that is, the horizontal direction when the frame 4 is viewed from the lower floor 100 </ b> A is defined as the width direction of the frame 4.

  Both ends in the longitudinal direction of the frame 4 are a lower floor horizontal section 4a and an upper floor horizontal section 4b, and the lower floor horizontal section 4a and the upper floor horizontal section 4b are formed using a support angle 6 and extended support members 21A and 21B. It is fixed to the lower floor 100A and the upper floor 100B.

  Further, a lower machine room 11 is provided in the lower floor horizontal part 4a of the frame 4, and an upper machine room 12 is provided in the upper floor horizontal part 4b. A lower sprocket 7 is disposed in the lower machine chamber 11, and an upper sprocket 8 and a step drive unit 9 are disposed in the upper machine chamber 12.

  A transmission chain 13 is wound around the upper sprocket 8 and the step drive unit 9. The upper sprocket 8 rotates when the step drive unit 9 is driven. An endless step chain 14 is wound around the lower sprocket 7 and the upper sprocket 8. When the step drive unit 9 is driven and the upper sprocket 8 rotates, the lower sprocket 7 and the step chain 14 rotate.

  The plurality of steps 5 are connected endlessly via a step chain 14 to form a series of conveyors. The plurality of steps 5 are guided by guide rails (not shown) attached to the frame 4 and circulate on the forward path side and the return path side. Passengers are transported on the steps 5 moving on the outward path side.

  A control panel 20 is disposed in each of the lower machine room 11 and the upper machine room 12. The control panel 20 is fixed to the frame 4 forming the lower machine room 11 or the upper machine room 12 using fixing bolts (not shown). The mounting position of the control panel 20 can be appropriately set as long as it does not interfere with the sprockets 7 and 8 and the step drive unit 9 in the machine room. Since the control panel 20 is electrically connected to a display 27 and a sensor 28 described later, a position close to the display 27 and the sensor 28 is preferable in consideration of wiring and the like.

Next, the balustrade member 15 will be described.

FIG. 2 is a cross-sectional view showing the machine room and the cover of the passenger conveyor, and FIG. 3 is a perspective view showing the machine room and the cover of the passenger conveyor.
As shown in FIGS. 2 and 3, the lower floor horizontal portion 4 a and the upper floor horizontal portion 4 b of the frame 4 are provided with a passenger conveyor floor 23 and a passenger conveyor floor frame 24 that supports the passenger conveyor floor 23. Yes. The passenger conveyor floor 23 extends from between the balustrade members 15 to the lower floor 100A or the upper floor 100B of the building structure 100.

[Support angle]
As shown in FIG. 2, the support angle 6 is formed in a substantially L shape when viewed from the extending direction. The support angle 6 is fixed to the upper end in the vertical direction at both ends in the longitudinal direction of the frame 4 (passenger conveyor floor frame 24). The support angle 6 includes a fixed piece 31 and a support piece 32. The support piece 32 is bent substantially continuously from one end of the fixed piece 31 and is continuous.

  The fixed piece 31 is fixed to the end of the frame 4 in the longitudinal direction by welding. Thereby, the fixed piece 31 becomes substantially parallel to the vertical direction, and the support piece 32 becomes substantially parallel to the horizontal direction. And the support piece 32 of the support angle 6 fixed to the lower floor 100A side protrudes toward the lower floor 100A of the building structure 100 from the frame 4. Further, the support piece 32 of the support angle 6 fixed to the upper floor 100B side protrudes from the frame 4 toward the upper floor 100B of the building structure 100.

  The support piece 32 is placed on the building cradle 101 </ b> B via the adjustment plate 34. The support piece 32 and the building cradle 101B may be fixed, and the support angle 6 may be the fixed end of the passenger conveyor 1, or the support angle 6 may be fixed to the passenger conveyor 1 without fixing the support piece 32 and the building cradle 101B. It is good also as a free end.

  As shown in FIG. 2, the hanging margin L <b> 1 of the support angle 6 on the building structure 100 is the end of the support piece 32 opposite to the fixed piece 31 from the wall surface 104 of the lower floor 100 </ b> A or the upper floor 100 </ b> B, that is, The length is up to the tip.

[Extension support member]
Next, the extension support members 21A and 21B will be described.
The extension support members 21 </ b> A and 21 </ b> B are fixed to both ends in the longitudinal direction of the frame 4. The extension support members 21 </ b> A and 21 </ b> B are disposed on the upper end of the frame 4 in the vertical direction, that is, on the upper surface of the upper frame constituting the frame 4. Furthermore, the extension support members 21A and 21B are arranged at both ends in the width direction of the frame 4 so as to sandwich the passenger conveyor floor 23 from both sides in the width direction. The extension support members 21A and 21B are fixed to the frame 4 by fixing bolts (not shown), for example.

  The extension support members 21A and 21B are formed in, for example, a substantially rectangular parallelepiped shape. One end in the longitudinal direction of the extension support members 21 </ b> A and 21 </ b> B is placed on the upper surface of the frame 4. The length of the passenger conveyor floor 23 parallel to the width direction of the frame 4 is smaller than the length of the frame 4 in the width direction. The distance between the extension support members 21A and 21B is substantially equal to the length of the passenger conveyor floor 23 parallel to the width direction of the frame 4, and the extension support members 21A and 21B protrude outside the width direction of the frame 4. There is no such thing.

  The other ends in the longitudinal direction of the extension support members 21A and 21B, that is, the distal ends of the extension support members 21A and 21B protrude from the ends in the longitudinal direction of the frame 4. And the protrusion length from the flame | frame 4 in extension support member 21A, 21B is set longer than the length from the fixed piece 31 in the support piece 32 of the support angle 6 to the front-end | tip part.

  Further, intermediate portions of the extension support members 21 </ b> A and 21 </ b> B protrude from the frame 4 and are placed on the upper surface in the vertical direction of the support piece 32 of the support angle 6. Furthermore, the front ends of the extension support members 21A and 21B are slidably mounted on the lower floor 100A or the upper floor 100B.

  As shown in FIG. 2, the hanging allowance L2 of the extension support members 21A and 21B to the building structure 100 is the length from the wall surface 104 of the lower floor 100A or the upper floor 100B to the tip of the extension support members 21A and 21B. It will be.

  As described above, the protruding length of the extended support members 21 </ b> A and 21 </ b> B from the frame 4 is set to be longer than the length of the support piece 32 of the support angle 6. Therefore, the length L2 of the extended support members 21A, 21B can be made longer than the length L1 of the extended angle of the support angle 6, and the length of the extended margin with the building structure 100 in the passenger conveyor 1 Can be extended as compared with the case where only the support angle 6 is provided.

  As a result, a large inter-layer displacement angle is generated by earthquake motion or the like, and the extension support members 21A and 21B are detached from the building structure 100 even when the dimension between the lower floor 100A and the upper floor 100B is relatively large. Can not be. As a result, the installation state of the frame 4 with respect to the building structure 100 can be easily maintained, and the earthquake resistance of the passenger conveyor 1 can be further improved with a simple configuration.

[cover]
However, since the extension support members 21A and 21B that protrude from the floor surface exist in the vicinity of the passenger conveyor floor 23 of the passenger conveyor 1, the safety of the passenger's feet is not taken into consideration as it is. Therefore, in the present embodiment, covers 22A and 22B that cover the extension support members 21A and 21B are arranged so that the extension support members 21A and 21B are not exposed under the feet of the passengers.

  As shown in FIG. 3, the covers 22 </ b> A and 22 </ b> B are formed in a hollow rectangular parallelepiped shape and face each other with a predetermined distance in the width direction of the frame 4. Since the configurations of the covers 22A and 22B are substantially the same, the configuration of the cover will be described here by taking the cover 22B as an example. The cover 22B has an upper surface 22a, a rear surface facing the balustrade member 15, a front surface 22b opposite to the rear surface, an inner side surface 22c facing the cover 22A, and an outer surface opposite to the inner side surface 22c. Yes.

  A handrail 26 is attached to the upper surface 22a of the cover 22B. The height of the handrail 26 can be determined as appropriate according to the height of the cover 22B. For example, the handrail 26 is set to a height that is easy for a passenger to grasp. Moreover, the indicator 27 which shows the driving | running direction of the passenger conveyor 1 is attached to the front surface 22b of the cover 22B, and the some sensor 28 is attached to the inner surface 22c.

  The plurality of sensors 28 are arranged on the front surface 22b side of the inner side surface 22c of the cover 22B, and are arranged at appropriate intervals in the vertical direction. The sensor 28 detects a passenger who has entered between the covers 22A and 22B. As the sensor 28, for example, a human sensor using infrared rays, ultrasonic waves, visible light, a camera, or the like can be applied.

  The display 27 and the plurality of sensors 28 are electrically connected to the control panel 20 disposed in the machine rooms 11 and 12 by wiring 30. The wiring 30 is accommodated in the cover 22B through a through hole (not shown) provided in the lower floor 100A or the upper floor 100B so as not to obstruct passengers. In addition, although the through-hole which lets the wiring 30 pass may be provided in the passenger conveyor floor 23, the wiring 30 is accommodated in the cover 22B also in that case.

  The control panel 20 controls the display of the display device 27 and takes in signals from the plurality of sensors 28 to control the driving of the step driving unit 9. For example, when the driving direction of the passenger conveyor 1 is switched, a signal is transmitted from the control panel 20 to the display device 27, and the direction of an arrow or the like displayed on the display device 27 is switched.

  Further, as a result of taking in the signals from the plurality of sensors 28, when the time when there is no passenger reaches a predetermined time, transmission of the drive signal from the control panel 20 to the step drive unit 9 is stopped, and the step 5 Stop circular movement. On the other hand, when the time when there is no passenger has not reached the predetermined time, a drive signal is transmitted from the control panel 20 to the step drive unit 9 to circulate the step 5.

  Thus, since cover 22A, 22B which covers extension support member 21A, 21B, respectively is provided, the safety | security of a passenger's leg | foot can be improved. Moreover, since these covers 22A and 22B are opposed to each other with a predetermined distance therebetween, it is possible to provide a guiding function for guiding passengers to the passenger conveyor 1 side.

  The covers 22A and 22B are opposed to the balustrade members 15 and 15 with a distance that does not allow passengers to pass therethrough, and have continuity for guiding the passengers to the balustrade members 15 and 15 and the covers 22A and 22B. It is As a result, the passenger enters the passenger conveyor 1 from the front surface 22b side of the covers 22A and 22B, and the passenger conveyor floor is used from the lower floor 100A or the upper floor 100B of the building structure 100 while using the handrail 26. 23. This guidance function is enhanced by configuring the indicator 27 on the passenger entrance side, which is the front side of the covers 22A and 22B. That is, the passenger can confirm the driving direction of the passenger conveyor 1 by the display 27 and can smoothly move to the passenger conveyor 1 on the boarding side.

  The control panel 20 for controlling the display device 27 attached to the covers 22A and 22B is disposed in the machine rooms 11 and 12. For this reason, although the indicator 27 and the control panel 20 are connected by the wiring 30, since the wiring 30 is accommodated in the covers 22 </ b> A and 22 </ b> B, the wiring 30 does not become an obstacle when passengers get on and off, and the safety of the feet. Can be increased.

  The covers 22A and 22B are provided on the lower floor 100A and the upper floor 100B, respectively. However, when the usage of the display is the display of the driving direction, the covers 22A and 22B are provided on the floor on the passenger conveyor on the passenger boarding side. You may attach an indicator only to the arranged cover. Further, the sensor 28 may determine the side to be attached according to the intended use.

  The passenger conveyor 1 according to the present embodiment is assembled as a new passenger conveyor using the existing frame 4 at the time of renewal. And the earthquake-proof strength with respect to the building structure 100 is improved with a simple structure by providing the extension support members 21A and 21B. Furthermore, the passenger conveyor 1 excellent in safety and functionality can be provided by providing the covers 22A and 22B.

1-2. Next, a method for renewing a passenger conveyor having the above-described configuration will be briefly described.
As shown in FIGS. 1 and 2, a support angle 6 is fixed to the frame 4 of the passenger conveyor 1 in advance. First, the extension support members 21A and 21B are fixed to the upper surface of the frame 4 using, for example, fixing bolts. Therefore, the extension support members 21A and 21B can be easily attached to the existing frame 4 where it is difficult to perform the welding operation.

  Next, covers 22A and 22B in which one end of the wiring 30 is connected to the display 27 and the sensor 28 are prepared. Then, the other end of the wiring 30 is connected to the control panel 20, and the extension support members 21A and 21B are covered by the covers 22A and 22B. Next, the covers 22A and 22B are fixed to the extension support members 21A and 21B using, for example, fixing bolts.

  The above-described operations are performed on the lower floor horizontal portion 4a and the upper floor horizontal portion 4b of the frame 4, respectively. Thereby, the renewal work of the passenger conveyor 1 is completed. In addition, the process concerning renewal of the passenger conveyor 1 is not limited to the order mentioned above. For example, the other end of the wiring 30 may be connected to the control panel 20 after the covers 22A and 22B are installed.

  Further, the cover 22A, 22B may be fixed as long as it is a component of the passenger conveyor 1, and may be fixed to the passenger conveyor floor 23, for example. Thereby, even if a large-scale interlayer displacement angle occurs due to seismic motion or the like, the covers 22A and 22B move together with the frame 4, and the distance between the control panel 20 and the covers 22A and 22B does not change. As a result, it is possible to prevent a large tension from being applied to the wiring 30, and disconnection of the wiring 30, connection between the wiring 30 and the control panel 20, or disconnection of the wiring 30 from the display unit 27 and the sensor 28. Can be prevented.

  By the renewal method of the passenger conveyor 1 described above, the allowance between the passenger conveyor 1 and the building structure 100 can be extended with a simple structure. As a result, it is possible to provide a passenger conveyor that is improved in earthquake resistance in a short time and at a low cost. In particular, it is possible to prevent the frame 4 from being detached from the building structure 100 even when a large interlayer displacement angle is generated by the earthquake motion and the dimension between the lower floor 100A and the upper floor 100B extends relatively large.

  In addition, although embodiment mentioned above demonstrated the example which attached extension support member 21A, 21B to the flame | frame 4 at the time of renewal of a passenger conveyor, it is not limited to this. That is, when newly manufacturing a passenger conveyor, the extension support members 21A and 21B may be attached to the frame 4 in advance.

2. Second Embodiment Next, a passenger conveyor according to a second embodiment will be described with reference to FIGS. 4 and 5.
FIG. 4 is a perspective view showing a state where the passenger conveyor cover according to the second embodiment permits entry, and FIG. 5 shows the passenger conveyor cover according to the second embodiment. It is a perspective view which shows the state which has made entry prohibition.

[cover]
The differences between the passenger conveyor and the building structure according to the second embodiment and the passenger conveyor and the building structure according to the first embodiment are covers 42A and 42B. Therefore, here, the covers 42 </ b> A and 42 </ b> B will be mainly described, and the same reference numerals are given to the portions common to the first embodiment, and the duplicate description will be omitted.

  As shown in FIGS. 4 and 5, the passenger conveyor 41 according to the second embodiment includes covers 42 </ b> A and 42 </ b> B that cover the extension support members 21 </ b> A and 21 </ b> B (see FIGS. 2 and 3). The covers 42A and 42B are formed in a hollow, substantially rectangular parallelepiped shape lower than the covers 22A and 22B according to the first embodiment, and face each other with a predetermined distance in the width direction of the frame 4.

  Since the configurations of the covers 42A and 42B are substantially the same, the main configuration of the cover will be described here by taking the cover 42B as an example. The cover 42B has an upper surface 42a, a rear surface facing the balustrade member 15, a front surface 42b opposite to the rear surface, an inner side surface 42c facing the cover 42A, and an outer surface opposite to the inner side surface 42c. Yes.

  On the upper surface 42a of the cover 42B, a pole 45 and a handrail 46 that can be moved while a passenger is grasping are attached. The height of the handrail 46 can be determined as appropriate according to the height of the cover 42B. A transparent or translucent protective plate is provided in a portion surrounded by the handrail 46 and the upper surface 42a of the cover 42B.

  The pole 45 is disposed on the front surface 22b side of the upper surface 42a, and a handrail 46 is disposed behind the pole 45. The pole 45 is formed in a columnar shape extending in the vertical direction. An end surface of the pole 45 opposite to the cover 42B is an inclined surface inclined so as to face the front. And the 1st indicator 47 which shows the driving direction of a passenger conveyor is attached to the inclined surface of the pole 45. As shown in FIG.

  A sensor 49 and a belt locking portion 50 are attached to the side of the peripheral surface of the pole 45 facing the cover 42A. The sensor 49 is the same as the sensor 28 attached to the covers 22A and 22B of the first embodiment, and detects a passenger who has entered between the covers 42A and 42B.

  An end portion of the entry prohibiting belt 51 attached to the cover 42a is detachably locked to the belt locking portion 50 (see FIG. 5). The entry prohibition belt 51 faces the belt locking portion 50 and is stored in the belt storage portion 52 when the passenger is permitted to enter (see FIG. 4).

  A second indicator 48 indicating the driving direction of the passenger conveyor 41 is attached to the front surface 42b of the cover 42B. A sensor 49 is attached to the inner side surface 42c. That is, a plurality of sensors 49 are provided, and are arranged at an appropriate distance in the vertical direction.

  The displays 47 and 48 and the plurality of sensors 49 are electrically connected to the control panel 20 disposed in the machine rooms 11 and 12 by wiring 30. The wiring 30 is accommodated in the cover 42B through a through hole (not shown) provided in the lower floor 100A or the upper floor 100B so as not to obstruct passengers. In addition, although the through-hole which lets the wiring 30 pass may be provided in the passenger conveyor floor 23, the wiring 30 is accommodated in the cover 42B also in that case.

  The control panel 20 controls the display of the indicators 47 and 48 and takes in signals from the plurality of sensors 49 to control the driving of the step driving unit 9. For example, when driving the passenger conveyor 41, a signal is transmitted from the control panel 20 to the display device 27, and an arrow indicating the operation direction is displayed on the display device 27 (see FIG. 4). In this case, the entry prohibition belt 51 is stored in the belt storage unit 52.

  In addition, when prohibiting passengers from entering the vehicle, a signal is transmitted from the control panel 20 to the display device 27, and the display device 27 is displayed with a "X" (X) or "minus (-)" to notify entry prohibition ( (See FIG. 5). Then, the entry prohibition belt 51 is pulled out from the belt storage portion 52, and the end portion of the entry prohibition belt 51 is engaged with the belt engagement portion 50. Thereby, it can be made to recognize a passenger visually and physically that boarding of a passenger is prohibited.

  Further, as a result of taking in the signals from the plurality of sensors 49, when the time when there is no passenger has reached a predetermined time, transmission of the drive signal from the control panel 20 to the step drive unit 9 is stopped, and the step 5 Stop circular movement. On the other hand, when the time when there is no passenger has not reached the predetermined time, a drive signal is transmitted from the control panel 20 to the step drive unit 9 to circulate the step 5.

  Thus, since the covers 42A and 42B that cover the extended support members 21A and 21B are provided, the safety of passengers' feet can be improved. Moreover, since these covers 42A and 42B are opposed to each other with a predetermined distance therebetween, it is possible to provide a guiding function for guiding passengers to the passenger conveyor 41 side.

  Further, the covers 42A and 42B are opposed to each of the balustrade members 15 and 15 with a distance so that the passenger cannot pass therethrough, and have continuity for guiding the passengers to the balustrade members 15 and 15 and the covers 42A and 42B. It is As a result, the passenger gets into the passenger conveyor 41 from the front surface 42b side of the covers 42A and 42B, and the passenger conveyor floor is used from the lower floor 100A or the upper floor 100B of the building structure 100 while using the handrail 46. 23. This guidance function is enhanced by configuring the indicators 47 and 48 on the passenger entrance side, which is the front side of the covers 42A and 42B. That is, the passenger can check the driving direction of the passenger conveyor 41 with the indicators 47 and 48, and can smoothly move to the passenger conveyor 41 on the boarding side. Moreover, since the wiring 30 is accommodated in the covers 42A and 42B, the wiring 30 does not become an obstacle when passengers get on and off, and the safety of the feet can be improved.

  The passenger conveyor 41 according to the present embodiment is assembled as a new passenger conveyor using the existing frame 4 at the time of renewal. And the earthquake-proof strength with respect to the building structure 100 is improved with a simple structure by providing the extension support members 21A and 21B. Furthermore, by providing the covers 42A and 42B, the passenger conveyor 41 excellent in safety and functionality can be provided.

  Moreover, the renewal method of the passenger conveyor 41 is the same as the renewal method of the passenger conveyor 1 concerning 1st Embodiment. That is, the extension support members 21A and 21B are fixed to the upper surface of the frame 4 using, for example, fixing bolts, and the extension support members 21A and 21B are covered with the covers 42A and 42B. Then, the covers 42A and 42B are fixed to the extension support members 21A and 21B using, for example, fixing bolts. The cover 42A, 42B may be fixed as long as it is a component of the passenger conveyor 41, and may be fixed to the passenger conveyor floor 23, for example.

  Also in the renewal method of the passenger conveyor 41, the effect similar to the renewal method of the passenger conveyor 1 can be acquired. That is, the allowance between the passenger conveyor 41 and the building structure 100 can be extended with a simple structure. As a result, it is possible to provide a passenger conveyor that is improved in earthquake resistance in a short time and at a low cost. In particular, it is possible to prevent the frame 4 from being detached from the building structure 100 even when a large interlayer displacement angle is generated by the earthquake motion and the dimension between the lower floor 100A and the upper floor 100B extends relatively large.

  In addition, 2nd Embodiment mentioned above is not limited to attaching extension support member 21A, 21B to the flame | frame 4 at the time of renewal of a passenger conveyor. That is, when newly manufacturing a passenger conveyor, the extension support members 21A and 21B may be attached to the frame 4 in advance.

  Further, in the above-described second embodiment, the belt storage portion 52 that protrudes from the peripheral surface of the pole 45 is provided. However, the passenger conveyor according to the present invention may be configured such that the entry prohibition belt is accommodated in the pole 45.

  As mentioned above, embodiment of the passenger conveyor of this invention was described including the effect. However, the passenger conveyor of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention described in the claims.

  For example, in the above-described first embodiment, the covers 22A and 22B are not provided with the entry prohibition belt and the belt locking portion. However, also in the first embodiment, the cover 22A, 22B may be provided with an entry prohibition belt and a belt locking portion. In that case, a belt storage portion may be provided separately, or a configuration of storing in the cover 22A or the cover 22B may be employed.

  Moreover, although embodiment mentioned above demonstrated the example which fixes extension support member 21A, 21B to the upper surface part of the upper frame in the flame | frame 4, it is not limited to this. For example, the extended support member may be formed of an L-shaped member bent substantially vertically and fixed to a vertical frame connecting the upper frame and the lower frame in the frame 4.

  In the above-described embodiment, an escalator in which a step is generated between steps is described as an example of an inclined passenger conveyor. However, as a passenger conveyor of the present invention, a plurality of steps in which no step is generated between steps is described. The present invention can also be applied to a motorized road having a so-called moving sidewalk.

  In this specification, words such as “parallel” and “orthogonal” are used, but these do not mean only strict “parallel” and “orthogonal”, but include “parallel” and “orthogonal”. Further, it may be in a state of “substantially parallel” or “substantially orthogonal” within a range where the function can be exhibited.
