Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a balustrade device for a passenger conveyor. [Background technology]
[0002] In a conventional passenger conveyor safety device, the gap around the moving handrail at the opening of the moving handrail storage compartment is covered with a protective plate. The protective plate is attached to the moving handrail storage compartment so that it can be opened and closed freely. When a foreign object enters the moving handrail storage compartment through the gap around the moving handrail, the protective plate opens toward the inside of the moving handrail storage compartment and a switch is operated, which stops the operation of the passenger conveyor (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-12784 Summary of the Invention [Problem to be solved by the invention]
[0004] In recent passenger conveyors, resin end caps are often attached to the inlet. The end caps have a strong structure to withstand collisions with luggage such as carry-on bags. In contrast, with the safety devices for conventional passenger conveyors such as those described above, if a relatively large foreign object is caught between the end cap and the moving handrail, it takes a great deal of effort to remove the object.
[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a passenger conveyor handrail device that can easily remove foreign objects that have been drawn into the inlet portion. [Means for solving the problem]
[0006] The railing device for a passenger conveyor according to the present disclosure comprises: a stop switch provided inside the inlet portion that stops operation of the passenger conveyor when operated; a handguard boot provided in the inlet portion that is displaceable between a normal position and an operating position where the stop switch stops operation of the passenger conveyor and that is displaced from the normal position to the operating position when a foreign object drawn into the inlet portion hits it; and an end cap body provided outside the handguard boot in the inlet portion that seals the gap between the moving handrail and the inner and outer deck boards; the handguard boot is fitted into the end cap body when in the normal position and is separated from the end cap body when displaced to the operating position. [Effects of the Invention]
[0007] According to the passenger conveyor handrail device of the present disclosure, foreign objects drawn into the inlet portion can be easily pulled out. [Brief explanation of the drawings]

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing the configuration of an escalator according to embodiment 1. In the figure, a truss 11 is installed between an upper floor and a lower floor of a building.
[0010] A plurality of steps 12 are supported on the truss 11. The plurality of steps 12 are connected together in an endless manner. In FIG. 1, only four of the plurality of steps 12 are shown.
[0011] The multiple steps 12 circulate along a travel route. The travel route includes an outbound route and a return route. The outbound route is a section where each step 12 picks up and transports passengers. The return route is a section where each step 12 returns from the end point of the outbound route to the start point of the outbound route.
[0012] A pair of parapet devices 13 are erected on the truss 11. An endless moving handrail 14 is provided on each parapet device 13. Each moving handrail 14 circulates in synchronization with the movement of the multiple steps 12.
[0013] Fig. 2 is a perspective view showing the main part of the balustrade device 13 of Fig. 1. An inlet portion 13a is provided at the end of the balustrade device 13 in the movement direction of each step 12. The inlet portion 13a is the portion where the moving handrail 14 enters the balustrade device 13.
[0014] The balustrade device 13 includes a balustrade glass 15, an inner deck board 16, an outer deck board 17, a skirt guard 18, a plurality of balustrade posts (not shown), a handrail guide rail (not shown), a handguard boot 19, and an end cap body 20.
[0015] The balustrade glass 15 is supported by a plurality of balustrade posts. The plurality of balustrade posts are erected on the truss 11 at intervals in the direction of movement of the step 12. The handrail guide rail is fixed to the balustrade glass 15 and guides the movement of the moving handrail 14.
[0016] The inner deck board 16 and the outer deck board 17 are arranged continuously at the lower end of the balustrade glass 15, spanning from the upper boarding / alighting entrance to the lower boarding / alighting entrance. The inner deck board 16 is provided on the step 12 side of the balustrade glass 15. The outer deck board 17 is provided on the opposite side of the balustrade glass 15 from the step 12.
[0017] The skirt guard 18 is disposed continuously from the upper entrance to the lower entrance on the step 12 side of the inner deck board 16. The skirt guard 18 also faces the side of each step 12 on the outward path.
[0018] The hand guard boot 19 is provided in the inlet portion 13a. The hand guard boot 19 is made of a stretchable material, such as rubber or soft resin. The hand guard boot 19 is provided with a boot opening 19a.
[0019] The end cap body 20 is provided on the outside of the handguard boot 19 in the inlet portion 13a. The end cap body 20 is made of a hard resin, such as polypropylene. The end cap body 20 closes the gap between the moving handrail 14 and the inner deck board 16 and the outer deck board 17 in the inlet portion 13a.
[0020] A cap opening 20a is provided in the end cap body 20. The moving handrail 14 enters the balustrade device 13 through the cap opening 20a and the boot opening 19a at the inlet portion 13a.
[0021] The opening area of the cap opening 20a is larger than the opening area of the boot opening 19a, so that a portion of the hand guard boot 19 is exposed within the cap opening 20a.
[0022] The end cap body 20 has an inner end cap 21 and an outer end cap 22. The inner end cap 21 closes the gap between the moving handrail 14 and the inner deck board 16 at the inlet portion 13a.
[0023] The outer end cap 22 is combined with the inner end cap 21. The outer end cap 22 also closes the gap between the moving handrail 14 and the outer deck board 17 at the inlet portion 13a.
[0024] Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Although not shown in Fig. 2, the balustrade device 13 further includes a stop switch 23, an operating piece 24, and a return spring 25.
[0025] Stop switch 23 is provided inside inlet portion 13a. Stop switch 23 stops the operation of the escalator when operated. Actuating piece 24 is provided between hand guard boot 19 and stop switch 23.
[0026] Hand guard boot 19 is displaceable between a normal position shown in Figures 2 and 3 and an actuated position shown in Figure 9. When hand guard boot 19 is displaced to the actuated position, stop switch 23 is operated via actuating piece 24, and operation of the escalator is stopped. In other words, the actuated position is a position where stop switch 23 stops operation of the escalator.
[0027] When the hand guard boot 19 is in the normal position, the operating piece 24 contacts the stop switch 23, but the stop switch 23 is not operated, and operation of the escalator is permitted. In other words, the normal position is a position where the stop switch 23 is not operated and operation of the escalator is permitted.
[0028] The return spring 25 applies a force to the hand guard boot 19 via the operating piece 24 in a direction returning the hand guard boot 19 from the operating position to the normal position.
[0029] Figure 4 is a perspective view of the inner end cap 21 of Figure 3. Figure 5 is a perspective view of the inner end cap 21 of Figure 4 as seen from the inside of the balustrade device 13. Figure 6 is a perspective view of the outer end cap 22 of Figure 3.
[0030] A plurality of recesses 21a are provided in one of the inner end cap 21 and the outer end cap 22, that is, in this example, the inner end cap 21. The plurality of recesses 21a are provided in a portion of the inner end cap 21 that overlaps with the outer end cap 22.
[0031] The other of the inner end cap 21 and the outer end cap 22, in this example the outer end cap 22, is provided with a plurality of through holes 22a. The plurality of through holes 22a are provided in a portion of the outer end cap 22 that overlaps with the inner end cap 21. Each through hole 22a is aligned with a corresponding recess 21a.
[0032] Fig. 7 is a perspective view showing the hand guard boot 19 of Fig. 3. The hand guard boot 19 is provided with a plurality of protrusions 19b.
[0033] When the hand guard boot 19 is in the normal position, each protrusion 19b is passed through a corresponding through-hole 22a and fitted into a corresponding recess 21a. That is, when the hand guard boot 19 is in the normal position, the protrusion 19b is fitted into the corresponding recess 21a.
[0034] The size of each protrusion 19b is slightly larger than the size of each recess 21a. Each protrusion 19b is press-fit into the corresponding recess 21a, which prevents the hand guard boot 19 from falling off the end cap body 20 during normal driving.
[0035] Each protrusion 19b is pulled out of the corresponding recess 21a and through-hole 22a when the hand guard boot 19 is displaced to the operative position. That is, the hand guard boot 19 is separated from the end cap body 20 when displaced to the operative position.
[0036] Furthermore, by displacing the hand guard boot 19 to the operating position, the inner end cap 21 and the outer end cap 22 can be separated.
[0037] Figure 8 is an explanatory diagram that shows a schematic diagram of a foreign object 30 being drawn into the inlet portion 13a of Figure 3. When the foreign object 30 drawn into the inlet portion 13a hits the hand guard boot 19, the hand guard boot 19 is displaced from the normal position to the actuated position against the return spring 25, as shown in Figure 9.
[0038] This causes the stop switch 23 to be operated via the operating piece 24, and the operation of the escalator is stopped.
[0039] Furthermore, each protrusion 19b is pulled out of the corresponding recess 21a and through-hole 22a, and the hand guard boot 19 is separated from the end cap body 20 and is no longer constrained by the end cap body 20. This relieves the pinched state of the foreign object 30, making it possible to pull out the foreign object 30, as shown in FIG.
[0040] When an attempt is made to remove the foreign object 30 from this state, the restoring force of the return spring 25 pushes the operating piece 24, displacing the hand guard boot 19 toward the normal position, as shown in Figure 11. At this time, the end cap body 20 is pushed by the multiple protrusions 19b, making it easier for the inner end cap 21 and the outer end cap 22 to separate, making it even easier to remove the foreign object 30.
[0041] In this type of balustrade device 13, the handguard boot 19 is fitted to the end cap body 20 and is separated from the end cap body 20 when displaced to the operating position. This ensures sufficient strength under normal circumstances, while allowing foreign objects 30 drawn into the inlet portion 13a to be easily removed.
[0042] This prevents damage to the balustrade device 13 caused by forcibly pulling out the foreign object 30, and prevents the escalator from being stopped for a long period of time due to damage to the balustrade device 13.
[0043] Furthermore, by displacing the hand guard boot 19 to the operating position, the inner end cap 21 and the outer end cap 22 can be separated, making it easier to pull out the foreign object 30 drawn into the inlet portion 13a.
[0044] When the hand guard boot 19 is in the normal position, each of the protrusions 19b is inserted into the corresponding through-hole 22a and fitted into the corresponding recess 21a. When the hand guard boot 19 is displaced to the operating position, each of the protrusions 19b is pulled out of the corresponding recess 21a and through-hole 22a.
[0045] Therefore, with a simple configuration, it is possible to separate the inner end cap 21 and the outer end cap 22. Furthermore, when removing the foreign object 30, the inner end cap 21 and the outer end cap 22 can be easily separated without using tools or the like.
[0046] Embodiment 2 Next, Figure 12 is a perspective view of the inner end cap 21 according to the second embodiment as seen from inside the balustrade device 13. Figure 13 is a perspective view of the main part of the end cap body 20 according to the second embodiment as seen from inside the balustrade device 13.
[0047] A spring support portion 21b is provided on the inner end cap 21. A plurality of compression springs 26 are attached to the spring support portion 21b.
[0048] The outer end cap 22 is provided with a spring receiving portion 22b. The spring receiving portion 22b faces the spring support portion 21b. When the outer end cap 22 is combined with the inner end cap 21, each compression spring 26 is compressed between the spring support portion 21b and the spring receiving portion 22b.
[0049] That is, each compression spring 26 is provided between the inner end cap 21 and the outer end cap 22. Each compression spring 26 applies a force to the inner end cap 21 and the outer end cap 22 in a direction that moves the inner end cap 21 and the outer end cap 22 away from each other.
[0050] Other configurations in the second embodiment are the same as those in the first embodiment.
[0051] In this type of balustrade device 13, multiple compression springs 26 are provided between the inner end cap 21 and the outer end cap 22. This allows the inner end cap 21 and the outer end cap 22 to be actively separated when the hand guard boot 19 separates from the end cap body 20. This makes it easier to pull out the foreign object 30 drawn into the inlet portion 13a.
[0052] In the second embodiment, the number of compression springs 26 is not particularly limited, and may be one or three or more.
[0053] In the second embodiment, the compression spring 26 may be supported on the outer end cap 22 side.
[0054] In the first and second embodiments, the number of recesses 21a, through holes 22a, and protrusions 19b is not particularly limited, and may be one or three or more.
[0055] In addition, in the first and second embodiments, an additional recess may be provided in the end cap body 20 at a location other than the overlapping portion between the inner end cap 21 and the outer end cap 22, and an additional protrusion corresponding to the additional recess may be provided on the hand guard boot 19. This makes it possible to more reliably prevent the hand guard boot 19 from falling off the end cap body 20 during normal driving.
[0056] Embodiment 3 14 is a perspective view showing a main part of a balustrade device 13 according to embodiment 3. In embodiment 3, the end cap body 20 is not divided into an inner end cap 21 and an outer end cap 22.
[0057] Other configurations in the third embodiment are the same as those in the first embodiment.
[0058] In such a balustrade device 13, the number of parts can be reduced and the configuration can be simplified compared to the first embodiment. Also, the balustrade device 13 can be easily assembled.
[0059] In the first to third embodiments, the operating piece 24 may be omitted, and the stop switch 23 may be operated directly by the handguard boot 19.
[0060] Furthermore, in the first to third embodiments, an escalator is shown as the passenger conveyor, but the passenger conveyor may be a moving walkway. [Explanation of symbols]
