JP5723217B2 - Passenger conveyor - Google Patents

Description

  The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a passenger conveyor in which a scattering prevention film is attached to a glass panel arranged along both sides of a step in the traveling direction.

  Passenger conveyors often use glass panels for the balustrade, and therefore the glass panels may be destroyed by impact or the like. It is also conceivable to use tempered glass with a mesh wire embedded as a balustrade glass panel, but such tempered glass may be naturally destroyed. When a glass panel breaks, glass pieces are scattered around and it is dangerous. Conventionally, as a measure for preventing the glass pieces from scattering, a method of attaching a scattering prevention film to the glass panel is known (for example, see Patent Document 1). . In addition, in the passenger conveyor described in patent document 1, the glass which adjoins mutually so that a scattering prevention film may be wound up to the end surface of the step movement direction of a glass panel, or the edge part of a scattering prevention film may be covered. By filling the gap between the panels with a caulking material, peeling of the anti-scattering film is prevented, and safety and appearance are maintained over a long period of time.

  In addition, in the existing passenger conveyor, it is difficult to apply the structure described in Patent Document 1 described above to the glass panel that constitutes the balustrade. There has been proposed a sheet of anti-scattering film adhered to an existing passenger conveyor that reliably prevents the broken glass panel from falling off (see, for example, Patent Document 2).

  Furthermore, conventionally, it has been proposed to fill a gap between adjacent glass panels with a caulking material (see, for example, Patent Document 3).

JP-A-5-319759 (paragraph numbers 0012 to 0015, FIGS. 1 and 2) JP 2010-215393 A (paragraph numbers 0017 to 0025, FIG. 3) Japanese Utility Model Publication No. 64-12074 (first page, FIG. 3)

  However, in the above-described Patent Document 1, since the caulking material is filled in the gap between the adjacent glass panels so as to cover the end portion of the anti-scattering film, the anti-scattering film is replaced. The caulking material also needs to be reworked, which causes a problem of increasing costs. Further, since the caulking material and the anti-scattering film are in contact with each other, the caulking material may promote deterioration of the anti-scattering film, and the anti-scattering film may be peeled off. In addition, there is a possibility that the caulking material filled in the gap between the glass panels may protrude from the surface of the glass panel. There is a concern to do.

  Moreover, in what is shown to patent document 2, when a glass panel is destroyed for some reason and it replaces | exchanges, since the anti-scattering film is pasted across two or more adjacent glass panels, it adjoins. It is also necessary to replace the shatterproof film of the glass panel that has not been destroyed. Since the application of the anti-scattering film must be performed locally, it was difficult to shorten the stoppage period of the passenger conveyor.

  In Patent Document 3, no consideration has been given to the anti-scattering film.

  The present invention is made from the actual state in the above-described prior art, and the purpose thereof is an existing one, which prevents the broken glass panel from falling off, and replaces the broken glass panel, and An object of the present invention is to provide a passenger conveyor capable of easily exchanging only the anti-scattering film.

  In order to achieve the above-mentioned object, the present invention comprises a glass panel that is connected endlessly and arranged in a plurality of rows through a predetermined gap along both sides in the traveling direction of steps that circulate between the entrances and exits. In passenger conveyors equipped with anti-scattering films attached to glass panels, the anti-scattering films are attached to the glass panels, and the gaps between adjacent glass panels protrude from the surfaces of these glass panels. In addition, an adhesive or a caulking material is filled so as not to come into contact with the anti-scattering film, and ends of adjacent glass panels are connected by the adhesive or the caulking material.

  In the present invention configured as described above, when one of the plurality of glass panels is broken for some reason, a glass piece is stuck to the anti-scattering film stuck to the broken glass panel. . At this time, since the broken glass panel is connected to the adjacent non-destructed glass panel via an adhesive or a caulking material, the broken glass panel does not fall off. In addition, the broken glass panel is removed together with the adhesive or caulking material filled in the gap between the adjacent glass panels and replaced with a new glass panel on which the anti-scattering film is pasted. The gap is filled with adhesive or caulking material, and the replacement operation is completed. Further, the replacement work of only the anti-scattering film is to peel off the existing one from each glass panel and attach a new one, and the adhesive or caulking material is used continuously.

  According to the present invention, in the existing passenger conveyor, when the glass panel is broken, the glass panel is prevented from dropping off integrally with the glass piece stuck to the anti-scattering film, and the safety is improved. Can be achieved. In addition, the replacement work of the broken glass panel can replace the broken glass panel alone without affecting the adjacent glass panel by preparing a new glass panel with an anti-scattering film attached. This makes it possible to work in a short time. Furthermore, the replacement work of only the anti-scattering film is to remove the existing one from each glass panel and attach a new one, and the adhesive or caulking material can be used as it is. Accordingly, the replacement work can be easily performed.

It is a schematic side view showing the whole passenger conveyor. It is a schematic sectional drawing which shows the Example of this invention. It is the partial schematic side view seen from A in FIG. It is arrow sectional drawing which follows the BB line of FIG.

  Embodiments of a passenger conveyor according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a passenger conveyor, for example, an escalator, is provided in the truss 1 in an endlessly connected state with the truss 1 installed between the two floors, and circulates between the entrances 2 and 3. A moving step 4, a plurality of sheets arranged side by side with a predetermined gap along both sides of the moving direction of the step 4, and a glass panel 5 constituting a balustrade and supported on the upper surface of the glass panel 5 as shown in FIG. Handrail deck 6, a handrail 7 that is mounted on the handrail deck 5 and circulates in synchronization with the step 4, a panel receiver 8 that supports the lower portion of the glass panel 5, and a step below the glass panel 5 An inner deck 9 disposed on the side and an outer deck 10 disposed on the opposite side of the lower side of the glass panel 5 are provided.

  In this embodiment, as shown in FIGS. 3 and 4, the anti-scattering film 11 is attached to each glass panel 5, 5 a, 5 b, and these glass panels are placed in the gap h between adjacent glass panels. For example, an adhesive 12 is filled so as not to protrude from the surface and to come into contact with the scattering prevention film 11, and the ends of adjacent glass panels are connected by the adhesive 12.

  In this embodiment, when one of the plurality of glass panels 5, 5 a, 5 b is broken for some reason, the scattering prevention film 11 stuck on the broken glass panel, for example, the glass panel 5. It will be in the state where the glass piece stuck to. At this time, since the broken glass panel 5 is connected to the adjacent non-broken glass panels 5a and 5b via the adhesive 12, the broken glass panel 5 does not fall off.

  The replacement work of the broken glass panel 5 is performed by removing the broken glass panel 5 together with the adhesive 12 filled in the gap between the adjacent glass panels 5a and 5b, and a new glass on which the scattering prevention film 11 is stuck. Then, the adhesive 12 is filled in the gap h between the adjacent glass panels 5a and 5b, and the operation is completed.

  When only the anti-scattering film 11 is exchanged, the existing anti-scattering film 11 is simply peeled off from each glass panel 5, 5a, 5b, and a new one is simply attached. At this time, the adhesive 12 is continuously used as it is.

  According to the present embodiment, in the existing passenger conveyor, when the glass panel 5 is broken, the glass panel 5 is prevented from dropping off integrally with the glass piece stuck to the anti-scattering film 11, Safety can be improved. Moreover, the replacement | exchange operation | work of the broken glass panel 5 replaces | disassembles the broken glass panel independently, without affecting an adjacent glass panel by preparing the new glass panel which affixed the scattering prevention film 11. FIG. Can be performed in a short time. Furthermore, the replacement work of only the anti-scattering film 11 is simply to peel off the existing one from each glass panel 5, 5a, 5b and attach a new one, and the adhesive 12 can be used as it is. Accordingly, the replacement work can be easily performed.

  In the above-described embodiment, the adhesive 12 is filled in the gap between the adjacent glass panels. However, the same effect can be obtained by filling the caulking material.
