Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a balustrade device for a passenger conveyor, a balustrade installation jig, and a balustrade installation method. [Background technology]
[0002] In conventional passenger conveyors, a moving handrail guide that guides a moving handrail is attached to the upper end of a balustrade panel. The moving handrail guide is attached over the entire length of the passenger conveyor and is divided into multiple guardrails (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-158386 Summary of the Invention [Problem to be solved by the invention]
[0004] In conventional passenger conveyors such as those described above, each guardrail is typically attached to a balustrade panel at the installation site. During this process, manufacturing errors in the guardrail itself, manufacturing errors in peripheral equipment, and installation errors in peripheral equipment can accumulate, resulting in gaps between adjacent guardrails or in the guardrails not fitting perfectly. For this reason, conventionally, one or more guardrails are manufactured longer than necessary and then cut to the final length at the installation site for installation.
[0005] However, because guardrails are made of metal and have complex cross-sectional shapes, cutting them requires special skills and is time-consuming.In addition, because guardrails are decorative parts that are exposed to the outside, thorough deburring and chamfering are required.
[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a passenger conveyor balustrade device, balustrade installation jig, and balustrade installation method that allow for easy installation of guardrails. [Means for solving the problem]
[0007] The railing device of a passenger conveyor according to the present disclosure comprises a first guardrail that guides a moving handrail, a second guardrail that is spaced apart from the first guardrail in the longitudinal direction of the first guardrail and also guides the moving handrail, and a sealant that is provided between the first and second guardrails and fills the gap between the first and second guardrails. In addition, the balustrade installation jig for a passenger conveyor according to the present disclosure is a balustrade installation jig for filling the gap between a first guardrail attached to the upper end of a balustrade panel and a second guardrail attached to the upper end of the balustrade panel at a distance from the first guardrail in the longitudinal direction of the first guardrail with a sealant, and is equipped with a first outer form on one side of the balustrade panel, spanning between the first and second guardrails and being applied to the outer surfaces of the first and second guardrails, and a second outer form on the other side of the balustrade panel, spanning between the first and second guardrails and being applied to the outer surfaces of the first and second guardrails. Furthermore, the railing installation method for a passenger conveyor according to the present disclosure includes the steps of: installing a first guardrail on the upper end of the railing panel; installing a second guardrail on the upper end of the railing panel at a distance from the first guardrail in the longitudinal direction of the first guardrail; fitting a first outer mold to the outer surfaces of the first and second guardrails on one side of the railing panel, straddling the first and second guardrails; fitting a second outer mold to the outer surfaces of the first and second guardrails on the other side of the railing panel, straddling the first and second guardrails; injecting a sealant into the inside of the first and second guardrails, straddling the first and second guardrails; inserting an inner mold into the inside of the first and second guardrails, straddling the first and second guardrails, and spreading the sealant in the gap between the first and second guardrails; and removing the first outer mold and the second outer mold. [Effects of the Invention]
[0008] According to the present disclosure, guardrails can be easily installed. [Brief explanation of the drawings]
[0009] [Figure 1] 1 is a schematic configuration diagram showing an escalator according to a first embodiment. [Figure 2] FIG. 2 is a cross-sectional view taken along line II-II in FIG. [Figure 3] FIG. 3 is a side view showing the main part of the balustrade device of FIG. 2. [Figure 4] FIG. 4 is a side view showing the balustrade device of FIG. 3 in the middle of being installed. [Figure 5] FIG. 5 is a cross-sectional view taken along line VV in FIG. DETAILED DESCRIPTION OF THE INVENTION
[0010] 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. The passenger conveyor in embodiment 1 is an escalator. In the figure, a truss 11 is installed between the upper and lower floors of a building.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 2 is a cross-sectional view taken along line II-II in FIG. 1, showing a cross section perpendicular to the direction of movement of the moving handrail 14. The handrail device 13 has a handrail panel 15, a buffer material 16, and a moving handrail guide 17.
[0015] The balustrade panel 15 is made of, for example, transparent glass. The balustrade panel 15 is erected on the truss 11. A buffer material 16 is attached to the upper end of the balustrade panel 15. The cross section of the buffer material 16 is U-shaped.
[0016] The moving handrail guide 17 is fixed to the upper end of the balustrade panel 15 via a buffer material 16. The moving handrail guide 17 also guides the moving handrail 14.
[0017] The moving handrail guide 17 has a fixed portion 17a and a pair of guide portions 17b. The fixed portion 17a is a portion that is fixed to the upper end of the balustrade panel 15. The pair of guide portions 17b are portions that are covered by the moving handrail 14. The pair of guide portions 17b are located above the fixed portion 17a.
[0018] When the escalator is in operation, the fixed portion 17a is exposed to the outside, but the pair of guide portions 17b is not exposed to the outside.
[0019] A panel insertion groove 17c is provided at the bottom of the fixed portion 17a by protruding the bottom surface upward. This forms a pair of recesses 17d within the fixed portion 17a. The panel insertion groove 17c is located between the pair of recesses 17d. The upper end of the balustrade panel 15 is inserted into the panel insertion groove 17c via the buffer material 16.
[0020] Fig. 3 is a side view showing the main part of the balustrade device 13 of Fig. 2. Fig. 3 shows a state in which the moving handrail 14 has been removed from the balustrade device 13.
[0021] The moving handrail guide 17 is made up of a plurality of guardrails. The plurality of guardrails are arranged in a line along the moving direction of the moving handrail 14, i.e., along the longitudinal direction of the moving handrail guide 17.
[0022] The multiple guardrails include a first guardrail 21 and a second guardrail 22. The first guardrail 21 and the second guardrail 22 are disposed adjacent to each other in the longitudinal direction of the moving handrail guide 17.
[0023] The second guardrail 22 is disposed with a gap between it and the first guardrail 21 in the longitudinal direction of the first guardrail 21. That is, a gap 23 is provided between the first guardrail 21 and the second guardrail 22.
[0024] At least one of the first guardrail 21 and the second guardrail 22 is manufactured to be short in advance so that a gap 23 is provided between the first guardrail 21 and the second guardrail 22.
[0025] A sealant 24 is provided between the first guard rail 21 and the second guard rail 22. The sealant 24 fills the gap 23. For example, a silicone-based sealant is used as the sealant 24.
[0026] The sealant 24 does not protrude from or retract into the gap 23 from the outer surfaces of the first guardrail 21 and the second guardrail 22. In other words, the outer surfaces of the sealant 24 are flush with the outer surfaces of the first guardrail 21 and the second guardrail 22. Therefore, no step is created between the sealant 24 and the first guardrail 21 or second guardrail 22.
[0027] When the moving handrail 14 is placed over the moving handrail guide 17, the upper end of the sealing material 24 is hidden inside the moving handrail 14 and is not exposed to the outside through the gap 23.
[0028] Fig. 4 is a side view showing a state in the middle of installation of the balustrade device 13 of Fig. 3. Fig. 5 is a cross-sectional view taken along line VV of Fig. 4.
[0029] A balustrade installation jig 30 is used when applying the sealant 24 between the first guardrail 21 and the second guardrail 22. The balustrade installation jig 30 is a jig for filling the gap 23 with the sealant 24. After the balustrade device 13 is installed, the balustrade installation jig 30 is removed from the balustrade device 13.
[0030] The balustrade installation jig 30 has a first outer mold 31, a second outer mold 32, and an inner mold 33. The cross-sectional shape of the first outer mold 31 and the cross-sectional shape of the second outer mold 32 are both L-shaped. The second outer mold 32 is the same member as the first outer mold 31 and is arranged symmetrically with respect to the first outer mold 31.
[0031] The first outer mold 31 is placed on one side of the balustrade panel 15, straddling the first guardrail 21 and the second guardrail 22, and is placed against the outer surfaces of the first guardrail 21 and the second guardrail 22.
[0032] The second outer mold 32 is placed on the other side of the balustrade panel 15, straddling between the first guardrail 21 and the second guardrail 22, and is placed against the outer surfaces of the first guardrail 21 and the second guardrail 22.
[0033] The first guardrail 21 has a first side surface 21a, a second side surface 21b, a first lower surface 21c, and a second lower surface 21d.
[0034] The first side surface 21a is the side surface of the first guardrail 21 on one side of the balustrade panel 15. The second side surface 21b is the side surface of the first guardrail 21 on the other side of the balustrade panel 15. The first lower surface 21c is the lower surface of the first guardrail 21 on one side of the balustrade panel 15. The second lower surface 21d is the lower surface of the first guardrail 21 on the other side of the balustrade panel 15.
[0035] The second guard rail 22 has a third side surface, a fourth side surface, a third lower surface, and a fourth lower surface.
[0036] The third side surface is the side surface of the second guardrail 22 on one side of the balustrade panel 15. The fourth side surface is the side surface of the second guardrail 22 on the other side of the balustrade panel 15. The third underside surface is the underside surface of the second guardrail 22 on one side of the balustrade panel 15. The fourth underside surface is the underside surface of the second guardrail 22 on the other side of the balustrade panel 15.
[0037] The first outer mold 31 is applied to the first side surface 21a, the first lower surface 21c, the third side surface, the third lower surface, and the balustrade panel 15. The second outer mold 32 is applied to the second side surface 21b, the second lower surface 21d, the fourth side surface, the fourth lower surface, and the balustrade panel 15.
[0038] The inner mold 33 is inserted between the first guardrail 21 and the second guardrail 22 and inside the first guardrail 21 and the second guardrail 22. In this way, the inner mold 33 spreads the sealant 24 throughout the gap 23.
[0039] Next, we will explain the balustrade installation method of Embodiment 1. The balustrade installation method of Embodiment 1 includes a first guardrail installation step, a second guardrail installation step, a first outer mold installation step, a second outer mold installation step, a pouring step, an inner mold insertion step, and a removal step.
[0040] The first guardrail installation process is a process of installing a first guardrail 21 on the upper end of the parapet panel 15. The second guardrail installation process is a process of installing a second guardrail 22 on the upper end of the parapet panel 15 at a distance from the first guardrail 21 in the longitudinal direction of the first guardrail 21.
[0041] The first outer form installation process is a process of placing the first outer form 31 on one side of the parapet panel 15, spanning between the first guardrail 21 and the second guardrail 22, and attaching it to the outer surfaces of the first guardrail 21 and the second guardrail 22.
[0042] The second outer form installation process is a process of placing the second outer form 32 on the other side of the parapet panel 15, spanning between the first guardrail 21 and the second guardrail 22, and attaching it to the outer surfaces of the first guardrail 21 and the second guardrail 22.
[0043] The injection step is a step of injecting uncured sealant 24 between the first guardrail 21 and the second guardrail 22 and inside the first guardrail 21 and the second guardrail 22.
[0044] The inner mold inserting step is a step of inserting the inner mold 33 between the first guardrail 21 and the second guardrail 22, inside the first guardrail 21 and the second guardrail 22, and spreading the sealant 24 into the gap 23. After the inner mold inserting step, the sealant 24 is hardened.
[0045] The removal process is a process of removing the first outer mold 31 and the second outer mold 32 from the balustrade device 13. In the removal process, the inner mold 33 is also removed from the balustrade device 13.
[0046] In such a balustrade device 13, balustrade installation jig 30, and balustrade installation method, the gap 23 is filled with the sealing material 24. Therefore, even if at least one of the first guardrail 21 and the second guardrail 22 is manufactured to be shorter in advance, no step is created in the gap 23.
[0047] Therefore, there is no need to cut the first guardrail 21 or the second guardrail 22 at the installation site, and the guardrail including the first guardrail 21 and the second guardrail 22 can be easily installed. In other words, the installation work can be simplified because the sealant 24 absorbs manufacturing errors and installation errors in the guardrails and peripheral equipment.
[0048] Furthermore, the outer surface of the sealing material 24 is flush with the outer surface of the first guard rail 21 and the outer surface of the second guard rail 22. Therefore, degradation of the design due to the gap 23 can be suppressed.
[0049] Furthermore, since the inner mold 33 is inserted inside the first guardrail 21 and the second guardrail 22, the sealant 24 can be sufficiently spread throughout the gap 23. Furthermore, the amount of sealant 24 required can be reduced.
[0050] The inner mold 33 has a cross-sectional shape as shown in Fig. 5. That is, the inner mold 33 has a block-shaped inner mold body and a pair of protrusions protruding downward from the inner mold body. The pair of protrusions are inserted into portions corresponding to the pair of recesses 17d in the first guard rail 21 and the second guard rail 22. This allows the sealant 24 to more reliably spread throughout the gap 23.
[0051] The sealant 24 may be provided at two or more guardrail joints.
[0052] Furthermore, if the sealant 24 can be sufficiently spread throughout the gap 23, the inner mold 33 and the inner mold inserting step may be omitted.
[0053] Furthermore, in the first embodiment, an escalator is shown as the passenger conveyor, but the passenger conveyor may be a moving walkway. [Explanation of symbols]
