  In this specification, the term “step” includes not only a plurality of steps of an escalator, but also a plurality of steps of a pallet-type moving sidewalk that leveles the escalator and a rubber belt-type moving sidewalk of a belt conveyor. Is also included.

(1) Embodiment (1-1) Configuration of Passenger Conveyor According to this Embodiment A configuration of a passenger conveyor according to this embodiment will be described with reference to FIGS. 1 and 4. The passenger conveyor 1 according to the present embodiment is an escalator having an earthquake-resistant structure that is installed so as to straddle a building upper floor 10 and a building lower floor 11 that are building structures. The step 3 connected endlessly in the main body frame 2 having a cross-sectional concave shape straddling the lower floor 11 of the building is configured to circulate and move between the upper floor and the lower floor diagonally upward or diagonally downward. The balustrades 4 are erected on both sides of the step 3 connected endlessly, and moving handrails 5 that run in synchronization with the step 3 are disposed on the balustrades 4 respectively.

  The main body frame 2 is fitted in a recess 25 formed in the building lower floor 11 at one end side (lower floor side) in the longitudinal direction, and is depressed by a building lower floor support angle 19a fixed to the front end portion thereof. The building upper floor side support angle 18a fixed to the other end side (upper floor side) in the longitudinal direction is supported by the building lower floor side angle cradle 19b formed in the building 25. It is installed so as to be supported by the building upper floor angle receiving base 18b.

  In this case, a building lower floor side clearance 14 having a predetermined width is provided between the building lower floor support angle 19a and the building lower floor angle cradle 19b, and the building upper floor support angle 18a and the building upper Even when the main body frame 2 moves in the longitudinal direction due to the occurrence of an interlayer displacement due to an earthquake or the like, a gap 13 is provided between the floor side angle cradle 18b with a predetermined width. When the movement is slight, it is effective that the main body frame 2 collides with the building upper floor 10 and the lower building floor 11 and the main body frame 2, the upper building floor 10 and the lower building floor 11 are damaged. It has been made to be able to prevent.

  The space between the building lower floor angle receiving base 19b and the building upper floor receiving angle 18b is the length of the main body frame 2 plus the building lower floor supporting angle 19a or the main body frame 2 and the upper floor floor. The length of the main body frame 2 is selected until the building lower floor support angle 19a abuts against the side surface of the building lower floor angle receiving base 19b as shown in FIG. 3 or when the main body frame 2 is moved until the building upper floor side support angle 18a contacts the side surface of the building upper floor side angle cradle 18b as shown in FIG. The support angle 19a can be prevented from coming off the building lower floor side angle cradle 19b, or the building upper floor side support angle 18a can be prevented from coming off from the building upper floor side angle cradle 18b. Uninasa are.

  Further, the passenger conveyor 1 is provided with an intermediate support 20 that supports the main body frame 2. The intermediate support 20 is provided with a slide member 21 that slides in the longitudinal direction when an interlayer displacement occurs, and a main body frame side support 22 is provided above the slide member 21, and a lower part of the slide member 21. Is provided with a building lower floor support 23. Thereby, even when the main body frame 2 moves in the longitudinal direction, the passenger conveyor 1 can be prevented from falling on the lower floor 11 of the building because it is supported by the slide member 21. The main body frame side support 22 is fixed to the main body frame 2, the building lower floor support 23 is fixed to the building lower floor 11, and the intermediate support 20 supports the middle in the longitudinal direction of the main body frame 2. To do. 1 to 3, the slide member 21 is fixed to the main body frame side support body 22, but the slide member 21 may be fixed to the building lower floor side support body 23.

  Further, the length in the longitudinal direction of the slide member 21 is selected to be longer than the building lower floor side gap 14 and the building upper floor side gap 13, and thereby the building lower floor side support angle 19 a as shown in FIG. 2. When the main body frame 2 moves until it touches the side surface of the building lower floor side angle cradle 19b, or the building upper floor side support angle 18a becomes the side surface of the building upper floor side angle cradle 18b as shown in FIG. Even when the main body frame 2 moves until it comes into contact with the sliding member 21, the sliding member 21 can be prevented from being detached from the building lower floor support 23.

  On the other hand, exterior side plates 6 that cover the side portions of the main body frame 2 are attached to both side portions of the passenger conveyor 1. The exterior side plate 6 has the other end side (upper floor side) in the longitudinal direction that covers the other end side (upper floor side) of the main body frame 2, the building upper floor side support angle 18 a and the building upper floor 10. It is formed longer than the main body frame 2 so as to cover the base portion of the building upper floor angle receiving base 18b from the side surface side.

  And the front-end | tip part of the other end side (upper floor side) of the exterior side board 6 is cut off from the other site | parts of the exterior side board 6, and the exterior side board clearance gap 27 of predetermined width is provided between these front-end | tip parts and other site | parts. ing. As a result, when the main body frame 2 moves in the longitudinal direction due to an earthquake or the like, the outer side plate 6 moving integrally with the main body frame 2 absorbs the displacement by the outer side plate gap 27 and the outer frame accompanying the movement of the main body frame 2. The side plate 6 can be prevented from being deformed or damaged.

  Further, on the one end side (lower floor side) in the longitudinal direction of the exterior side plate 6 that covers one end side (lower floor side) of the main body frame 2, a triangular triangular cover portion 6 a that covers the intermediate support 20 from the side surface side. Is formed. As shown in FIG. 5, the exterior side plate 6 is attached to the main body frame 2 so that the lower end surface of the triangular cover portion 6 a is slightly lifted from the building lower floor 11 and faces the building lower floor 11. Accordingly, a suppression guard gap 17 having a predetermined height is provided between the lower end surface of the exterior side plate 6 and the lower floor 11 of the building. Thus, even when a large interlayer displacement occurs due to an earthquake or the like and the main body frame 2 moves in the longitudinal direction, the triangular cover portion 6a of the exterior side plate 6 does not receive any resistance from the lower floor 11 of the building. The frame 2 can move freely in the longitudinal direction of the main body frame 2, thus preventing the exterior side plate 6 from being damaged due to the main body frame 2 moving in the longitudinal direction.

  In addition, on the lower end side of the triangular cover portion 6a of the exterior side plate 6, a shake suppression guard mechanism 15 having substantially the same length as the lower end portion of the triangular cover portion 6a is disposed. The shake suppression guard mechanism 15 includes an inner L-shaped guard 15a having an L-shaped cross section disposed inside the triangular cover portion 6a of the exterior side plate 6, and a cross-section L disposed outside the triangular cover portion 6a. The outer L-shaped guard 15b has a letter shape, and the lower ends of the triangular cover 6a of the exterior side plate 6 are sandwiched between the vertical portions 16a and 16b of the inner L-shaped guard 15a and the outer L-shaped guard 15b. It is arranged along the longitudinal direction of the main body frame 2. Further, the horizontal portions 16c and 16d of the inner L-shaped guard 15a and the outer L-shaped guard 15b are fixed to the building lower floor 11 with bolts 24 and the like, respectively, whereby the width of the triangular cover portion 6a of the exterior side plate 6 is increased. The deflection of the direction (the direction perpendicular to the longitudinal direction of the main body frame 2, hereinafter referred to as the width direction of the main body frame 2) can be suppressed.

(1-2) Effects of the present embodiment In the passenger conveyor 1 according to the present embodiment having the above-described configuration, when a large interlayer displacement occurs due to an earthquake or the like, the main body frame 2 is a building lower floor side angle cradle. It moves in the longitudinal direction between 19b and the building upper floor side angle cradle 18b. At this time, since the exterior side plate 6 is not fixed to the building lower floor 11, it can move in the longitudinal direction of the main body frame 2 together with the main body frame 2. Therefore, according to the passenger conveyor 1, damage to the exterior side plate 6 can be prevented even when an interlayer displacement occurs due to an earthquake or the like.

  Moreover, in this passenger conveyor 1, since the lower end part of the triangular-shaped cover part 6a of the exterior side plate 6 is hold | maintained so that it may be pinched | interposed by the inner side L-shaped guard 15a and the outer side L-shaped guard 15b which comprise the shake suppression guard mechanism 15. The outer side plate 6 can be prevented from moving in the width direction of the main body frame 2 of the outer side plate 6 without obstructing the movement of the outer side plate 6 in the longitudinal direction of the main body frame 6 integrally with the main body frame 6.

  Furthermore, in this passenger conveyor, even if there is a suppression guard gap 17 between the building lower floor 11 and the exterior side plate 6, it can be covered by the shake suppression guard 15. Thus, the dimensional tolerance at the time of production and assembly of the exterior side plate 6 can be relaxed without deteriorating the appearance, and the production time and assembly time of the passenger conveyor 1 can be shortened and the cost can be reduced.
