Embodiment 1.
FIG. 1 is a perspective view of a passenger conveyor to which the entrance / exit safety device of the passenger conveyor according to the first embodiment is applied.

The passenger conveyor in FIG. 1 is an escalator. The main frame 1 is erected between the building beams on the upper floor and the building beams on the lower floor. The main frame 1 supports the weight of the passenger conveyor and the weight of the user.

The plurality of steps 2 are connected in an endless manner. Each of the plurality of steps 2 is provided so that the user can ride on it. The plurality of steps 2 are provided so as to be able to move in a circular manner.

The pair of balustrades 3 are arranged on both sides of the plurality of steps 2. The pair of balustrades 3 are formed of a glass panel or the like.

The pair of moving handrails 4 are arranged on both sides of the plurality of steps 2. The pair of moving handrails 4 are provided so as to be able to circulate in synchronization with the plurality of steps 2.

The pair of guide rails 5 are provided on the tops of the pair of balustrades 3, respectively. The pair of guide rails 5 guide the pair of moving handrails 4, respectively.

The pair of skirt guards 6 are arranged on both sides of the plurality of steps 2. The pair of skirt guards 6 are continuously arranged along the moving direction of the plurality of steps 2 with a slight gap between the plurality of steps 2 and the plurality of steps 2.

The floor plate 7 forms a boarding / alighting port of a passenger conveyor by a plurality of covers. The upper surface of the floor plate 7 is arranged on the same surface as the upper surface of the surrounding building floor surface 8.

The comb plate 9 is made of a thick steel plate or the like. The comb plate 9 is connected to the floor plate 7 at the support portion on the rear end side. The comb plate 9 meshes with the cleat of the step 2 at the comb 10 on the front end side. The upper surface of the comb plate 9 is slightly inclined toward the front end side to form a part of the entrance / exit.

Next, the comb plate 9 will be described with reference to FIGS. 2 and 3.
FIG. 2 is a cross-sectional view taken along the line AA of FIG. FIG. 3 is a cross-sectional view taken along the line BB of FIG.

The comb plate 9 includes a stepped portion 9a, a stepped portion 9b, and a decorative plate 9c.

The stepped portion 9a is provided on the rear end side of the comb plate 9. The stepped portion 9a supports the landing plate 7a, which is a part of the adjacent floor plate 7, from below. The stepped portion 9b is provided on the front end side of the comb plate 9. A comb 10 is attached to the stepped portion 9b. The decorative plate 9c is attached to the upper surface of the comb plate 9.

The left and right ends of the comb plate 9 are attached to a pair of existing angle-shaped receivers 1a that are welded to the main frame 1 and form a part of the main frame 1 so that the front end side can be displaced upward.

Specifically, the shaft mounting plate 17 is fixed to the existing receiver 1a. The shaft mounting plate 17 includes a short shaft 17a. The minor axis 17a projects toward the comb plate 9.

The comb plate 9 includes a block 18. The block 18 is fixed to the upper surface on the rear end side of the comb plate 9 at a position facing the minor axis 17a. The block 18 includes a through hole 18a. The through hole 18a rotatably accepts the minor axis 17a. As a result, the rear end side of the comb plate 9 is rotatably supported with the short axis 17a as the center of rotation.

The block 18 is fixed by screwing the bolt 26 into the screw hole 9e of the comb plate 9 with the scissors 25 inserted so that the height of the rear end side of the comb plate 9 is aligned with the building floor surface 8.

The height of the front end side of the left and right ends of the comb plate 9 is the same as when the entrance / exit safety device is not equipped, so that the engagement allowance 13 between the comb 10 and the cleat of the step 2 becomes the specified value. It is finely adjusted by the contact bolt 14 screwed into.

The bolt 27 is screwed into the screw hole 1d of the existing receiver 1a via the cap 29 that covers the coil spring 28 with a predetermined gap 30 open. The coil spring 28 urges the comb plate 9 downward with a predetermined pressing force.

In the unlikely event that a foreign substance is caught in the gap 31 between the cleat groove on the tread surface of the comb 10 and the tread 2, the front end side of the comb plate 9 may be pushed upward with the short shaft 17a of the shaft mounting plate 17 as the center of rotation. And. When the pushing force at this time becomes larger than the pushing force by the coil spring 28, the front end side of the comb plate 9 is pushed up to a position where the gap 30 disappears. At this time, the gap 30 is set so as not to be pushed up more than necessary until the meshing allowance 13 is exhausted.

The bolt 16 has a very small gap 32 with the side surface of the comb plate 9 so as not to interfere with the engagement between the comb 10 and the cleat of the step 2 and the upward pushing up of the front end side of the comb plate 9. It is screwed in the state.

The expansion lever 33 is fastened together with the contact bolt 14. The expansion lever 33 expands the amount of push-up on the front end side of the comb plate 9. The expansion lever 33 operates the limit switch 34 fixed to the main frame 1 when the front end side of the comb plate 9 is pushed up by a predetermined amount when a foreign object is caught between the comb 10 and the step 2. As a result, the passenger conveyor stops.

Next, a method of fixing the shaft mounting plate 17 will be described with reference to FIGS. 4 to 6.
FIG. 4 is an exploded perspective view of a main part of the entrance / exit safety device of the passenger conveyor according to the first embodiment. FIG. 5 is a side view of a main part of the entrance / exit safety device of the passenger conveyor according to the first embodiment. FIG. 6 is a cross-sectional view taken along the line CC of FIG.

In the shaft mounting plate 17, the mounting plate portion 17b is formed integrally with the shaft at the shaft end of the short shaft 17a. The lower side 17c of the shaft mounting plate 17 is fixed to the elevation surface 1b of the receiver with bolts 19 while being mounted on the existing receiver 1a. At this time, the distance 24 from the end surface 7b of the landing plate 7a to the short shaft 17a is aligned on the left and right shaft mounting plates 17. Further, the short shaft 17a is arranged very close to the joint portion between the comb plate 9 and the existing landing plate 7a.

The existing receiver 1a does not have a screw hole for screwing the bolt 19. Therefore, in the passenger conveyor, a screw hole is made in the existing receiver 1a.

FIG. 7 is a side view of a main part showing a method of drilling a screw hole in the existing receiver 1a of the passenger conveyor according to the first embodiment. FIG. 8 is a cross-sectional view taken along the line DD of FIG.

The drill guide 20 is a jig for drilling a screw hole for screwing a bolt 19 into an existing receiver 1a, and a temporary fixing bolt 21 is already installed in a state where it is applied to an end surface 7b of an existing landing plate 7a adjacent to a comb plate 9. It is temporarily fixed by being screwed into the screw hole 1c.

In this state, the undercut hole of the bolt 19 is machined by inserting a drill (not shown) into the guide hole 20a of the drill guide 20. Therefore, the height 22 from the upper surface of the existing receiver 1a to the screw hole 1e constructed and the distance 23 from the end surface 7b of the existing landing plate to the screw hole 1e constructed are aligned on the left and right.

According to the first embodiment described above, the shaft mounting plate 17 can be easily fixed to the existing receiver 1a in a state where the comb plate 9 is removed. Therefore, since fire such as welding is not used, there is no need to worry about ignition of the chain refueling or the like in the passenger conveyor or operation of the sprinkler in the store, and the entrance / exit safety device can be retrofitted in a short time.

Further, the lower side 17c of the shaft mounting plate 17 is placed on the upper surface of the existing receiver 1a. Therefore, an excessive shearing force does not act on the bolt 19 that fixes the shaft mounting plate 17 in the normal use state of the passenger conveyor.

The minor shaft 17a of the shaft mounting plate 17 is arranged very close to the joint between the comb plate 9 and the landing plate 7a. Therefore, even if the user makes an abnormal ride such as jumping on the landing plate 7a, the moment for lifting the front end side of the comb plate 9 acts very little around the short axis 17a. In particular, even if the user jumps very close to the joint between the comb plate 9 and the landing plate 7a, the moment for lifting the front end side of the comb plate 9 acts very little.

For example, as shown in FIG. 3, when the load due to the user's jump is F and the distance from the rear end to the shaft end of the comb plate 9 is L, the moment is F × L. At this time, since the distance L is short, a large moment that lifts the front end side of the comb plate 9 does not occur, and it is possible to prevent the retrofitted entrance / exit safety device from malfunctioning.

Further, the axes of the left and right short shafts 17a are aligned, and the left and right short shafts 17a do not have a crank shape. As a result, when a foreign substance is sandwiched between the comb 10 and the step 2, the front end side of the comb plate 9 can be smoothly lifted.

A similar entrance / exit safety device may be applied to the entrance / exit on the upper floor side. In this case as well, the entrance / exit safety device can be easily retrofitted.

Further, the entrance / exit safety device of the first embodiment may be applied to a newly installed passenger conveyor. Further, the passenger conveyor of the first embodiment may be applied to a moving walkway. In these cases as well, the entrance / exit safety device can be easily attached.

As described above, the passenger conveyor entrance / exit safety device according to the present invention can be used for the passenger conveyor system.
