Description

  The present invention relates to a balustrade panel removal tool, and more particularly to a tool used for removing a balustrade panel which is a constituent member of an escalator and other passenger conveyors.

  In a passenger conveyor, for example, in an escalator, a balustrade having a plurality of balustrade panels arranged along the passage on both sides of a passage of a passenger including a traveling path of a step that is circularly connected and circulates, is a constituent member. is set up. As the balustrade panels, in recent years, while the emphasis is placed on designability, glass bales are often used (Patent Literature 1, Patent Literature 2, Patent Literature 3, Patent Literature 4). The balustrade panel made of glass has a shatterproof film adhered to one surface of a reinforced plate glass.

  The shatterproof film is generally adhered to the entire surface of the main surface of the strengthened glazing opposite to the passage (hereinafter referred to as “outside”). This is because if the film is adhered to the side of the aisle (hereinafter referred to as “inside”), the anti-scattering film is rubbed by the shoes, baggage, etc. of the passengers, and becomes dirty, thereby impairing the design.

  Each of the balustrade panels has its lower edge supported by a plurality of fixtures spaced along the lower edge. Guide rails for guiding the moving handrail are provided at the upper edge of the balustrade panel installed on both sides of the traveling path, and at the upper edge and the arc-shaped edge of the balustrade panel installed at the elevator (entrance). It is mounted directly or via a mounting member.

  The balustrade panels are replaced with new ones when the shatterproof film deteriorates over time. In this case, first, the balustrade panel to be replaced is removed. Specifically, conventionally, a suction cup for glass with a handle is adsorbed to the inner surface of the tempered glass sheet, and the suction cup for glass is fixed to a balustrade panel. Next, the guide rail is removed from the upper edge or the arc-shaped edge, and the lower edge is released from being fixed by the fixing device. Then, the balustrade panel is lifted by grasping the handle and removed from the fixing device.

  Further, the tempered glazing is also replaced when the tempered glazing is so-called spontaneously damaged such that the reinforced glass is cracked into grains.

  In this case, the suction cup cannot be adsorbed to the cracked surface (the inner surface) of the tempered glass sheet, so that the glass suction cup cannot be used as a removal tool.

  For this reason, conventionally, the balustrade panel is directly supported by a hand wearing gloves or the like and removed from the fixing device. That is, the user stands on the step next to the damaged balustrade panel, reaches for the lower end edge between the fixing devices, supports the balustrade panel, and removes the balustrade panel from the fixing device.

  However, as a scaffold, the work of bending down on an unstable step, reaching the lower edge of the balustrade panel, and supporting the balustrade panel becomes inefficient.

  In addition, the above-mentioned subject is common to not only the escalator but also the removal of other passenger conveyors, for example, the balustrade panel which comprises a moving sidewalk.

  In view of the above-mentioned problems, an object of the present invention is to provide a balustrade panel removal tool that can be used for removing even a balustrade panel whose tempered glass sheet is naturally damaged.

  In order to achieve the above object, the balustrade panel removal tool according to the present invention has a plurality of glass balustrade panels erected along a passage of a passenger including a traveling path of an endless transporter that carries a passenger by circulating and traveling. A balustrade panel removal tool used for removing the balustrade panel of a passenger conveyor, comprising: a plate member; an adhesive layer formed on a first main surface of the plate member; and a second main member of the plate member. And a handle provided on the surface side.

  Further, the first main surface includes an adhesive surface corresponding to a main surface portion exposed on the passage side of the balustrade panel installed on the passenger conveyor, and the adhesive layer is provided on the adhesive surface. Is formed.

  Further, in a state where the adhesive surface is adhered to the main surface portion of the target balustrade panel to be removed, the stopper part overlaps with an adjacent balustrade panel adjacent to the target balustrade panel in a front view, and the stopper includes the adjacent balustrade. It is characterized in that it has a stopper portion that abuts against the main surface of the panel on the passage side to prevent the target balustrade panel from dropping to the side opposite to the passage while removing the target balustrade panel. .

  In this case, the stopper portion is a plate member portion of the plate member extending from the portion including the bonding surface to the adjacent panel side.

  Alternatively, the entirety of the first main surface is the bonding surface, and the stopper is attached to the second main surface.

  Further, the plate member is made of plastic corrugated cardboard whose streaks are parallel to the upper edge of the target balustrade panel, and the handle is fixed to a long substrate adhered to the second main surface, and The substrate is provided on the second main surface side, and the substrate is bonded to the second main surface with its length direction intersecting the streak.

  According to the balustrade panel removing tool having the above configuration, by pressing the first main surface toward the balustrade panel main surface, the balustrade panel removing tool can be adhered and fixed by the adhesive layer. The balustrade panel can be removed with the handle provided on the main surface side. As described above, since the bonding is performed by the pressure-sensitive adhesive layer formed on the main surface (first main surface) of the plate member, the balustrade panel removal tool is fixed even if the reinforced glass plate is a naturally damaged balustrade panel. Can be provided for removal of the balustrade panel.

  Hereinafter, an embodiment of a balustrade panel removal tool according to the present invention will be described by taking a balustrade panel removal tool for an escalator as an example.

<Overall configuration of escalator>
First, the escalator 10 from which the balustrade panel is to be removed will be described. As shown in FIG. 1, the escalator 10 has a plurality of steps 12 that are endlessly conveyed in a circular manner and circulate and convey passengers. Balustrades 14 and 16 are installed on both sides of a passenger path PW including a traveling path of the steps 12 and upper and lower elevators (entrances and exits).

  Each of the balustrades 14, 16 has a plurality of balustrade panels 17, 18,..., 18, 19 erected along the passage PW (in FIG. 1, the balustrade panel is a balustrade panel constituting one of the balustrades 14). Only the symbols are given.). Each of the balustrade panels 17, 18, and 19 is made of glass, and includes a tempered glass sheet and a shatterproof film attached to a predetermined area of the tempered glass sheet, as described later.

  Here, when it is necessary to particularly distinguish end balustrade panels provided at both ends in the row arrangement direction among the plurality of balustrade panels 17, 18, 19, the end balustrade panels are referred to as "Newell panels 17, 19". ". In other words, the Newell panels 17 and 19 are balustrade panels provided at the entrance (exit or entrance) of the passage PW. A balustrade panel other than the Newell panels 17 and 19 is referred to as an "intermediate panel 18".

  On the outer periphery of the plurality of balustrade panels 17, 18, and 19, an endless belt shape guided by guide rails (not shown in FIG. 1) and circulating and running in synchronization with the step 12 (ie, in the same direction and at the same speed) is provided. Moving handrails 20, 22 are provided, respectively. The moving handrails 20 and 22 guided by the guide rails travel in the horizontal direction in a section (section where passengers grab) along the upper ends of the plurality of balustrade panels 17, 18, and 19, and then curve and straighten. It leans obliquely, curves again, and runs again in the horizontal direction.

  The escalator 10 is installed, for example, between a lower floor DS and an upper floor US in a building. The escalator 10 switches the direction of travel of the steps 12 and is used for ascending or descending, and the passengers riding on the steps 12 move from the lower floor DS to the upper floor US or from the upper floor US to the lower floor DS. It is transported to the lower floor DS.

  In the escalator, if the balustrade panels constituting each of the balustrades 14 and 16 are formed as a single body (one piece), the balustrade panel becomes very long. Therefore, for the reasons of manufacturing and the like, the plurality of balustrades are divided as described above. As a mode of this division, as shown in FIG. 1, a so-called “vertical split”, which is vertically divided with respect to the inclination angle of the escalator (the angle of the skew of the moving handrails 20 and 22), and the inclination angle Regardless, there is a so-called "vertical split" (not shown) divided in the vertical direction.

  The escalator includes a type in which the number of steps (steps) that are horizontal at the entrance and the exit (hereinafter, referred to as “the number of horizontal steps”) is 1.5 and a type in which the number is three. is there. The number of horizontal steps of the escalator 10 is 1.5.

  The shape of the balustrade panel differs depending on whether it is vertical or vertical, and whether the number of horizontal steps is 1.5 or 3.

<Balustrade>
Next, the balustrades 14 and 16 will be described. The balustrade 14 and the balustrade 16 are installed symmetrically with the passage PW interposed therebetween, and have basically the same configuration. Therefore, the balustrade 14 will be described with reference to FIG. 2, and the description of the balustrade 16 will be omitted. FIG. 2 is a diagram cut along a plane orthogonal to the traveling direction of the moving handrail 20 in a section where the moving handrail 20 is skewed. In FIG. 2, a fixing device 26 described later is shown without being cut, and hatching of cut surfaces of other members is omitted for convenience.

  The balustrade panel 18 constituting the balustrade 14 includes a square tempered glass sheet 182 and a shatterproof film 184 attached to a part of the surface of the tempered glass sheet 182 by an adhesive (not shown). The tempered glass sheet 182 is, for example, a transparent glass, and the shatterproof film 184 is, for example, a transparent film. In the drawing, the thickness of the shatterproof film 184 is exaggerated compared to the thickness of the tempered glass sheet 182.

  The scattering prevention film 184 is for literally preventing the shards from scattering when the strengthened plate glass 182 is broken, and is made of, for example, polyester. The area where the shatterproof film 184 is adhered to the tempered glass sheet 182 will be described later.

<Fixing devices, etc.>
As shown in FIG. 2, each of the balustrade panels 18 constituting the balustrade 14 is fixed to the truss 28 by a plurality (for example, two) of fixing devices 26 each having a lower end portion installed along the passage PW. Have been. Since the fixing devices 26 have the same configuration, only one fixing device 26 will be described.

  The fixing device 26 has a fixing bracket 30 and a movable bracket 32. The fixing bracket 30 is fixed to the truss 28 by bolts 34B and nuts 34N, which are fastening members, and the fixing device 26 is attached to the truss 28. The fixing bracket 30 is fixed to the truss 28 by two sets of bolts 34B and nuts 34N, but only one of the bolts 34B and nut 34N appears in FIG.

  The outer deck 40 is attached to the fixed bracket 30 by bolts and nuts 36.

  Next, details of the fixing device 26 will be described with reference to FIG. The fixing device 26 has the fixed bracket 30 and the movable bracket 32 as described above.

  The fixing bracket 30 has a bolt insertion hole 44 through which the bolt 34B (FIG. 2) is inserted when the fixing bracket 30 is fixed to the truss 28 (FIG. 2). The fixed bracket 30 is formed with a receiving surface 46 that forms a vertical surface while being fixed to the truss 28. The receiving surface 46 is a surface facing the main surface portion of the lower end of the balustrade panel 18 opposite to the passage PW in a state where the balustrade panel 18 is fixed and supported by the fixing device 26 as described later (FIG. 2).

  The movable bracket 32 is pivotally supported by the fixed bracket 30 by a shaft 48 so as to be swingable as described later. The shaft 48 is obtained by subjecting both ends of a cylindrical round bar to so-called double chamfering. By this double chamfering, plate-like portions 48A having two parallel surfaces are formed at both ends of the shaft 48 (only one end is shown in FIG. 3D). In the shaft 48, a cylindrical portion 48B other than the plate portion 48A is inserted into a hole (not shown) penetrating the fixing bracket 30 in the vertical direction in FIG. 3A, and only the plate portion 48A is fixed. It protrudes from both side surfaces 30A of the bracket 30. A corresponding key groove (not shown) is formed in each of the holes (not shown) formed in the cylindrical portion 48B of the shaft 48 and the fixed bracket 30, and the shaft 48 is provided with the corresponding holes (not shown). ), The cylindrical portion 48B is non-rotatably attached by a parallel key (not shown).

  The movable bracket 32 has a pair of arm portions 50 extending leftward at both ends in the vertical direction in FIG. At the tip of each of the arm portions 50, a darling hole 52 (only one is shown in FIG. 3B) penetrating in the vertical direction is formed. The darling hole 52 includes a circular portion 52A and an elongated hole portion 52B communicating therewith. The width of the long hole portion 52B is large enough to allow the plate-like portion 48A of the shaft 48 to engage without rattling. The diameter of the circular portion 52A is slightly larger than the diameter of the cylindrical portion 48B of the shaft 48.

  Then, the plate-like portion 48 </ b> A of the shaft 48 is inserted into both the ball holes 52, and the movable bracket 32 is attached to the fixed bracket 30. In the state shown in FIG. 3B in which the plate-shaped portion 48A is engaged with the elongated hole 52B of the darnal hole 52, the movable bracket 32 cannot swing with respect to the fixed bracket 30 around the axis of the shaft 48. It becomes. On the other hand, when the movable bracket 32 is pushed in the direction of the arrow A and the plate portion 48A enters the circular portion 52A of the darling hole 52, the movable bracket 32 can swing around the axis of the shaft 48.

  Here, the state in which the plate-shaped portion 48A is engaged with the elongated hole portion 52B (enters to the back) and is engaged is referred to as the "fixed state" of the movable bracket 32 with respect to the fixed bracket 30. The state in which the portion 48A is disengaged from the elongated hole portion 52B and remains in the circular portion 52A is referred to as the "movable state" of the movable bracket 32 with respect to the fixed bracket 30.

  The movable bracket 32 has, in a fixed state, a support portion 54 that supports the lower end surface of the balustrade panel 18 (FIG. 2) via cushion pads 76 and 78 described later. The support portion 54 has a substantially rectangular plate shape. In FIG. 3A, the two arm portions 50 extend to the left from both ends in the vertical direction of the support portion 54.

  The movable bracket 32 rises vertically from the end opposite to the two arm portions 50 in the support portion 54, and has opposed portions 56 and 58 facing the receiving surface 46 of the fixed bracket 30 in a fixed state. Each of the facing portions 56 and 58 has two female screws (four in total, not shown) formed in a direction perpendicular to the receiving surface 46 of the fixed bracket with the movable bracket 32 fixed to the fixed bracket 30. ) Are formed, and press-contact bolts 60, 62, 64, 66, which are press-contact members, are screwed into the respective female screws. Lock nuts 68, 70, 72, 74 are screwed into the press contact bolts 60, 62, 64, 66, respectively.

  Cushion pads 76 and 78, which are cushion members made of a flat elastic member such as rubber, are adhered to the upper surface of the support portion 54 of the movable bracket 32.

  Returning to FIG. 2, between the lower end of the balustrade panel 18 and the receiving surface 46 of the fixing bracket 30, a cushion sheet 80, which is an elastic member made of rubber or the like, is sandwiched. The main surface of the cushion sheet 80 has the same shape as the receiving surface 46, and the cushion sheet 80 is adhered to the receiving surface 46 in a state where the cushion sheet 80 overlaps the receiving surface 46.

  Between the lower end of the balustrade panel 18 and the tips of the pressure contact bolts 60, 62, 64, 66 (only two of them are shown in FIG. 2), a part of a cantilevered support 84 and a pressure contact plate are provided. 82 is sandwiched. The press-contact plate 82 is a plate body having a two-layer structure (a double-layer structure is not shown in the figure) formed by laminating a rectangular steel plate and a rubber sheet having the same rectangular shape. It is sandwiched between the rubber sheets. The support 84 is made of a metal plate bent in an inverted “L” shape. An inner deck 86 described below is attached to the support 84.

  A part of the lower end surface of the balustrade panel 18 is in contact with the upper surfaces of the cushion pads 76 and 78 (only the cushion pad 76 is shown in FIG. 2), and the lower end surface is movable via the cushion pads 76 and 78. It is supported by the support portion 54 of the bracket 32. Note that the cushion pads 76 and 78 are not indispensable constituent members and may be omitted. In that case, the balustrade panel 18 is supported by the support portion 54 with its lower end surface in contact with the support portion 54.

  In the state shown in FIG. 2, the press-contact bolts 60, 62, 64, 66 screwed (attached) to the female screws (not shown) of the facing portions 56, 58 facing the receiving surface 46 are strongly tightened. The lower end of the balustrade panel 18 is pressed against the receiving surface 46 via the press-contact plate 82 and the support 84 so that the balustrade panel 18 is fixedly supported by the truss 28 at the lower end. In order to prevent the press contact bolts 60, 62, 64, 66 from loosening, the locking nuts 68, 70, 72, 74 are tightened.

  The upper end of the support member 84 fixed as described above to the fixing device 26 that supports the balustrade panel 18 on the truss (not shown) at the lower end edge thereof has an eave portion 84A projecting from the balustrade panel 18 side to the passage PW side. Is formed.

  In order to release the fixing of the attachment member 106 to the balustrade panel 18, as shown in FIG. 6, a pull-up bolt 130 into which a nut 128 is screwed is used. A female screw (not shown) is formed on the upper surface of the wedge member 124 at a position different from the position pressed by the holding bolt 126 (FIG. 5). Corresponding to the female screw, a long hole 118G, a long hole 114B, and a long hole 106B communicating with each other are formed in the bottom plate portion 118A, the handrail deck 114, and the mounting member 106, respectively. The slot 118G, the slot 114B, and the slot 106B are opened such that the direction perpendicular to the paper surface is the width direction, and the width is larger than the nominal diameter of the pull-up bolt 130, and the width of the nut 128 It is set to a smaller length.

  In the above configuration, when the wedge member 124 is loosened, first, the holding bolt 126 (FIG. 5A) is loosened, and further the screw is screwed upward until the tip (lower end) enters the female screw 106A. .

  Next, as shown in FIG. 6A, the pull-up bolt 130 is screwed into a female screw (not shown) formed on the wedge member 124. Then, the nut 128 is turned in the direction of the arrow, and the nut 128 is screwed downward. When the nut 128 is turned even after the nut 128 is in contact with the upper surface of the bottom plate portion 118A, the pull-up bolt 130 is screwed upward relative to the nut 128, and the pull-up bolt 130 is screwed together. The wedge member 124 is pulled upward. In this manner, the wedge member 124 is loosened, and the fixing of the mounting member 106 to the balustrade panel 18 is released.

  When the wedge member 124 is pulled up to the maximum as shown in FIG. 6B, the mounting member 106 is fitted to the upper end of the balustrade panel 18 with play in the thickness direction of the balustrade panel 18 (FIG. 6B). 5 (b), FIG. 6 (b)).

<Balustrade panel>
In the balustrade panel 18 in this example, for example, when the tempered glass sheet 182 is replaced due to natural damage, when detached from the unlocked fixing device 26 and the mounting member 106, fragments at the upper edge and the lower edge are possible. The following ingenuity has been made so as not to fall off as much as possible.

  FIG. 7 is a diagram illustrating the balustrade panel 18 alone. FIG. 7A is a front view showing the passage PW side in the installed state, FIG. 7B is a rear view showing the side opposite to the passage PW, and FIG. FIG. In all the drawings including this drawing, the scale between the members is not unified. In particular, in the figure showing the balustrade panel, the thickness of the shatterproof film with respect to the thickness of the tempered glass sheet is exaggerated. In FIG. 7, FIG. 14 (a), and FIG. 15 (a), the scattering prevention film is hatched.

  Here, in the strengthened glazing constituting the balustrade panel, in a state where the balustrade panel is installed, the main surface opposite to the passage PW is referred to as “first main surface”, and the main surface serving as the passage PW side is referred to as “first main surface”. 2 main surfaces ".

  Conventionally, the shatterproof film is stuck only on the first main surface of the tempered glass sheet. On the balustrade panel 18, as shown in FIG. 7, in addition to the first main surface 182A of the tempered glass sheet 182, the second main surface An anti-scattering film 184 was adhered to a region (FIG. 7C) including the upper edge 182U and the lower edge 182L of 182B.

  Here, the upper edge (182U) of the tempered glass sheet (182) is an area having a constant width from the upper end surface (182Ue), and is a member mounting member (106) for mounting the guide rail (118) to the tempered glass sheet. Is an area to which is attached. The lower edge (182L) of the tempered glass sheet (182) is an area having a fixed width from the lower end surface (182Le) and is an area fixed by the fixing device (24). Specifically, in the present example, the upper edge 182U is a region including a portion sandwiched between the first side wall 120A of the attachment member 106 and the wedge member 124, as shown in FIG. The lower edge 182L is an area including a portion of the fixing device 26 that is sandwiched between the press-contact plate 82 and the receiving surface 46. In an escalator having no lighting fixture or the like, the upper edge of the tempered glass when the guide rail is directly attached to the tempered glass sheet is an area where the guide rail is fitted.

  As shown in FIG. 7B and FIG. 7C, the balustrade panel 18 has an anti-scattering film 184 attached to the entire first surface 182A of the tempered glass sheet 182.

  On the other hand, as shown in FIG. 2 and FIG. 7C, the second main surface 182B of the tempered glass sheet 182 is attached to the upper edge 182U and the lower edge 182L. The anti-scattering film 184 attached to the upper edge 182U is further extended downward and attached, and the anti-scattering film 184 attached to the lower edge 182L is further extended upward and attached. Have been.

  From the viewpoint of preventing the pieces from falling off from the upper and lower ends of the naturally damaged tempered glass sheet 182, it is preferable to attach the scattering prevention film 184 with a width as large as possible at the upper and lower ends of the second main surface 182B. . However, if the width is increased too much, a part that is visually recognized by passengers appears. If the scattering prevention film portion that is visually recognized by passengers becomes dirty, the design property is impaired.

  Therefore, on the second main surface 182B, at least the upper edge 182U and the lower edge 182L are included, and the shatterproof film 184 is attached to a region that is not visible to the passenger.

  In this example, as shown in FIG. 5A, on the second main surface 182 </ b> B of the reinforced sheet glass 182, the shatterproof film 184 attached to the region sandwiched by the wedge members 124 (that is, the upper edge 182 </ b> U). Is further extended downward and attached.

  In this example, even if the scattering prevention film 184 slightly protrudes downward from the upper edge 182U, the protruding portion is hidden by the handrail deck 114 or the like and is not visually recognized by passengers. Therefore, at the upper end of the second main surface 182B, the area where the anti-scattering film 184 is adhered is not only limited to the upper edge 182U but also to the area up to the maximum range that is hidden by the handrail deck 114 and is not visible to passengers. The film 184 is stuck.

  Further, at the lower end of the second main surface 182B, even if it protrudes slightly upward from the lower edge 182L, the protruding portion is hidden by the inner deck 86 or the like and is not visually recognized by passengers. Therefore, at the lower end of the second main surface 182B, the area where the anti-scattering film 184 is attached is not limited to the lower edge 182L, but also to the area up to the maximum range hidden by the inner deck 86 or the like and not visible to passengers. The film 184 is stuck.

  In FIG. 7A, a main surface exposed on the side of the passage PW in a front view in a state where the balustrade panel 18 is installed on the escalator 10 is an inner area defined by two dashed lines. In this example, it is the second main surface 182B) of the strengthened glass sheet 182 (hereinafter, referred to as "exposed surface 18E").

  The anti-scattering film 184 attached to the second main surface 182B is folded back to the second main surface 182B from the portion of the anti-scattering film 184 attached to the first main surface 182A that protrudes from the first main surface 182A. It is the part that was stuck. It is not always necessary to attach to the upper end surface 182Ue and the lower end surface 182Le of the tempered glass sheet 182 (the adhesive does not need to be interposed between the shatterproof film 184 and the upper end surface 182Ue and the lower end surface 182Le). ).

  As described above, in the balustrade panel 18, in addition to the entire first main surface 182A of the tempered glass sheet 182, the lower end edge portion 182L and the mounting member 106 supported by the fixing device 26 are mounted on the second main surface 182B. A scattering prevention film 184 is stuck on a region including the upper edge 182U. For this reason, for example, when the strengthened glass plate 182 is naturally damaged and the balustrade panel 18 is replaced, even if the upper edge 182U is caught on the handrail deck 114 or the lower edge 182L is caught on the fixing device 26, the debris is broken. Can be prevented from falling off as much as possible. Further, the area where the anti-scattering film 184 is adhered on the second main surface 182B is limited to an area that is not visually recognized by the passenger, and thus does not impair the design.

<Balustrade panel removal tool>
The balustrade panel removal tool (hereinafter simply referred to as “removal tool”) 132 used when the tempered glass sheet 182 is spontaneously damaged and cracked into particles, and the glass suction cup cannot be used as the removal tool, is shown in FIGS. This will be described with reference to FIG.

  As shown in FIG. 8, the removal tool 132 includes a plastic cardboard (hereinafter, referred to as “pladan”) 134 as a plate member and one or a plurality of (four in this example) handle units attached to the platen 134. 136. The plastic cardboard is a known plate material.

  As shown in FIG. 9, the pradan 134 has a structure in which a plurality of parallel ribs (streaks) 1346 are sandwiched between two liner plates 1342, 1344. The pradan 134 is made of, for example, polypropylene. Here, the length direction of the rib 1346 is called a so-called “streak”. The pladan 134 has a property that it is relatively easy to bend in a direction intersecting the streaks (particularly, a direction orthogonal to the streaks) and hard to bend in the direction of the streaks.

  Returning to FIG. 8, the (principal surface) of the prada 134 has a shape that matches the exposed surface 18 </ b> E of the balustrade panel 18. That is, the lateral dimension L1 of the pladan 134 is substantially the same as the lateral dimension G1 of the balustrade panel 18 (FIG. 7A). The vertical dimension L2 of the prada 134 is almost the same as the distance G2 between the two dashed lines in FIG.

  As shown in FIG. 9, an adhesive layer 138 is formed on the first main surface 134A of the Pradan 134. A release paper 140 is laminated on the side of the adhesive layer 138 opposite to the first main surface 134A. The pressure-sensitive adhesive layer 138 is formed by peeling off one release paper (not shown) of a double-sided tape (the whole is not shown) and bonding it to the first main surface 134A. The release paper 140 is the other release paper in the double-sided tape. As the double-sided tape, for example, a strong adhesive double-sided tape corresponding to one of JISZ 1541 (ultra-strong double-sided adhesive tape) No. 1 can be used. As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 138, for example, an acrylic foam pressure-sensitive adhesive can be used.

  Returning to FIG. 8, each of the handle units 136 is provided on the second main surface 134B side of the prada 134. As shown in FIG. 10, the handle unit 136 includes a long substrate 142 and one or more (three in this example) handles 146 fixed to the substrate 142.

  The substrate 142 is made of, for example, an L-shaped aluminum angle material, and has an elongated rectangular flat plate portion 1422 and a rising portion 1424 rising vertically from a long side of the flat plate portion 1422. Since the substrate 142 has the rising portions 1424, the rigidity against bending in the length direction of the rising portions 1424 is high.

  The handle 146 is made of, for example, a molded product made of aluminum or hard plastic, and is fixed to the flat plate portion 1422 of the substrate 142 by a screw or an adhesive (not shown).

  An adhesive layer 148 is formed on a main surface (hereinafter, referred to as “back surface”) on the back side of the flat plate portion 1422 opposite to the handle 146. A release paper 150 is laminated on the side of the pressure-sensitive adhesive layer 148 opposite to the back surface. The pressure-sensitive adhesive layer 148 is formed by peeling off one release paper (not shown) of a double-sided tape (the whole is not shown) and bonding it to the back surface. The release paper 150 is the other release paper in the double-sided tape.

  The handle unit 136 is fixed to the pladan 134 by peeling off the release paper 150 and pressing the exposed pressure-sensitive adhesive layer 148 against the second main surface 134B of the pladan 134.

  In this case, as shown in FIG. 8A, the length direction of the substrate 142 is made to intersect (in this example, orthogonally) the direction of the streaks indicated by the arrow B in the prada 134, and the handle unit 136 is moved. By fixing to the platen 134, reinforcement of the platen 134 against bending in a direction orthogonal to the streaks can be achieved.

<Removal procedure of balustrade panel>
Next, a procedure for removing the balustrade panel 18 using the removal tool 132 having the above configuration will be described.

  (i) Remove the inner deck 86 and the skirt guard 90 (FIG. 2) corresponding to the balustrade panel 18 to be removed.

  (ii) The release paper 140 (FIG. 9) is peeled from the prada 134 of the removal tool 132.

  (iii) The pressure-sensitive adhesive layer 138 thus exposed is pressed against the exposed surface 18 </ b> E of the balustrade panel 18 in the direction of arrow H shown in FIG. 2, and the removal tool 132 is attached to the balustrade panel 18 by the adhesive force of the pressure-sensitive adhesive layer 138. Fix it.

  In this case, even if the reinforced plate glass 182 of the balustrade panel 18 is naturally damaged, the flatness is maintained when the upper and lower edges are fixed to the mounting member 106 and the fixing device 26, so that the passage PW By simply pressing from the side, the removal tool 132 can be fixed to the balustrade panel 18 by bonding.

  (iv) Next, the fixing between the mounting member 106 and the fixing device 26 is released. If the fixing between the attachment member 106 and the fixing device 26 is released without fixing the removal tool 132, the naturally damaged balustrade panel 18 loses planarity and flexes irregularly, making it difficult to handle. Become. Further, by bending, fragments in the non-sticking region of the scattering prevention film 184 with respect to the second main surface 182B of the strengthened glass sheet 182 easily fall off from the scattering prevention film 184 bonded to the first main surface 182A.

  In this regard, by attaching the removal tool 132 to the balustrade panel 18, even after the fixing of the attachment member 106 and the fixing device 26 is released, the balustrade panel 18 is kept flat, so that the handling becomes easy. . Further, the same effect as when the shatterproof film is adhered to most of the non-sticking area of the shatterproof film 184 on the second main surface 182B, that is, the exposed surface 18E of the balustrade panel 18, that is, it is literally spontaneously damaged. The effect of preventing the granular fragments of the reinforced sheet glass 182 from falling off and scattering can be obtained.

  (v) While holding the handle 146, as shown in FIG. 11, the balustrade panel 18 is lowered in the direction of the arrow D, that is, downward, from the state shown by the dashed line, and the upper end edge is attached to the mounting member 106. The balustrade panel 18 can be removed to the side of the passage PW by swinging the lower part in the direction of the arrow S.

<Modification of balustrade panel removal tool>
(Modification 1)
In the removal tool 132, the prada 134 was shaped to match the exposed surface 18E of the balustrade panel 18, and was adhered to the balustrade panel 18 by the adhesive layer 138 formed on the first main surface 134A. That is, all of the first main surface 134A is an adhesive surface to the balustrade panel 18, and the adhesive surface has a shape conforming to the exposed surface 18E as a matter of course.

  On the other hand, in the removal tool 152 according to Modification Example 1, as shown in FIG. 12A, the pradadan 154, which is a component, is a balustrade panel 18 to be removed (hereinafter referred to as a "balustrade panel 18r"). ) To the side of the balustrade panel 18 (hereinafter, referred to as a “pan balustrade panel 18n1” or “balustrade panel 18n2”) adjacent to both sides of the balustrade panel 18r from an adhesive portion 154AD including a bonding surface for the balustrade panel 18r. Each has a Pradan 154 portion SP (a range portion indicated by an arrow sp) that extends and overlaps each of the balustrade panel 18n1 and the balustrade panel 18n2 in a front view. Hereinafter, in Pradan, a portion including an adhesive surface to a balustrade panel to be removed is referred to as an “adhesive portion”, and a portion extending from the adhesive portion to a balustrade panel side adjacent to both sides of the balustrade panel to be removed. Is referred to as a “stopper portion”.

  The reason why the stopper 154SP is provided so as to extend from the bonding portion 154AD in the prada 154 of the removal tool 152 is as follows. In the case of the removal tool 132 (FIG. 8) of the above embodiment, since the entirety of the prada 134 overlaps the balustrade panel 18 r, when removing the balustrade panel 18 r using the removal tool 132, the balustrade panel 18 r is mistakenly removed (the removal tool 132). Together with the passage PW). Therefore, by providing the stopper portion 154SP as described above, when the balustrade panel 18r is about to fall to the side opposite to the passage PW, the stopper portion 154SP contacts the main surface of the balustrade panel 18n1 and the balustrade panel 18n2 on the passage PW side. The contact prevents the fall.

(Modification 2)
The removal tool 152 according to the first modification has a configuration in which the stopper portion 154SP extends from the bonding portion 154AD of the prdan 154 over the entire length of the width. However, in the removal tool 156 according to the second modification, FIG. As shown in (b), a configuration in which a part in the width direction is extended as a stopper 158SP (a range indicated by an arrow sp) from the bonding portion 158AD (a range indicated by an arrow ad) of the prdan 158 is adopted.

(Modification 3)
In the removal tools 152 and 156 according to the first and second modifications, the stoppers 154SP and 158SP are configured by a part of the prdan 154 and 158. However, the removal tool 160 according to the third modification is separate from the pradadan. Is provided with a stopper portion.

  As shown in FIG. 13, the removal tool 160 has a configuration in which stoppers 162 and 164 are added to the removal tool 132 of the above embodiment. In the removal tool 160, the same components as those of the removal tool 132 are denoted by the same reference numerals, and description thereof will be omitted.

  Each of the stopper portions 162, 164 is made of, for example, an aluminum plate. Each of the stopper portions 162, 164 is attached to the second main surface 134B of the prada 134 by bonding or the like. In a state where the removal tool 160 (the first main surface 134A) is adhered to the balustrade panel 18r as shown in the drawing, the stopper portion 162 is arranged such that a part thereof overlaps the balustrade panel 18n1 and the balustrade panel 18n2 in a front view. , 164 are attached to the second main surface 134B of the prada 134.

  Also in the removal tool 160, a part of the stopper portions 162, 164 abuts the main surface of the balustrade panel 18n1 and the balustrade panel 18n2 on the passage PW side, so that the balustrade panel 18r being removed falls to the side opposite to the passage PW. Is prevented.

<Tools for removing balustrade panels used for balustrade panels other than intermediate panels>
The removal tools 132, 152, 156, and 160 for the intermediate panel 18 have been described above. Next, the removal tools for removing the Newell panels 17 and 19 will be described.

  First, the configuration of the Newell panels 17 and 19 will be described with reference to FIGS. 14 (a) and 15 (a). Note that all the balustrade panels exemplified in FIGS. 14A and 15A are similar to the balustrade panels 18 (FIG. 7), and are made of a shatterproof film adhered to the entire first main surface of the reinforced sheet glass. The part protruding from the first main surface is folded back to the second main surface side and adhered to the second main surface. 14 (a) and 15 (a), the range of the lower edge supported by the fixing device (26) and the edge to which the mounting member (106) is mounted in the reinforced glass panel of the balustrade panel exemplified in FIGS. The range is described by specifying only the range along the outer periphery of the tempered glass sheet.

  As shown in FIG. 14 (a), the tempered glass sheet 172 constituting the Newell panel 17 includes an arc-shaped edge projecting in the horizontal direction, and the moving handrail 20 (FIG. 1) reverses the running direction. 20 (hereinafter, a guide rail for guiding the moving handrail so that the traveling direction of the moving handrail is reversed in the strengthened sheet glass). Is referred to as an “inverted edge”.) 172R. Therefore, a scattering prevention film 174 having a width substantially equal to that of the upper edge 172U is also attached to the reversing edge 172R of the second main surface 172B. Also, a scattering prevention film 174 is attached to the lower edge 172L of the second main surface 172B.

  The edge indicated by reference numeral 172N, that is, the edge between the inverted edge 172R and the lower edge 172L (hereinafter, the edge between the inverted edge and the lower edge of the strengthened glass sheet is referred to as an “intermediate edge”. It is not always necessary to attach the scattering prevention film 174 as shown in the figure. This is because the intermediate edge portion 172N is not supported by the fixing device 26 or the attachment member 106 is not attached.

  In FIG. 14A, an inner area defined by a dashed line is a second main surface 172B portion (hereinafter, referred to as an “exposed surface 17E”) that is exposed to the passage PW when the Newell panel 17 is installed. .)

  As shown in FIG. 15A, also on the Newell panel 19, on the second main surface 192B of the tempered glass sheet 192, the shatterproof film 194 having substantially the same width is formed over the upper edge 192U and the inverted edge 192R. It is stuck. Also, a scattering prevention film 194 is attached to the lower edge 192L. The shatterproof film 194 is not attached to the intermediate edge 192N.

  In FIG. 15A, an inner region defined by a dashed line is a second main surface 192B portion (hereinafter, referred to as an “exposed surface 19E”) that is exposed to the passage PW when the Newell panel 19 is installed. .)

  A detaching tool for the above-configured Newell panels 17 and 19 (having the above-described shape) will be described.

  First, as shown in FIG. 14B, the removal tool 200 for the Newell panel 17 has a Pradan 202 having a shape matching the exposed surface 17E of the Newell panel 17 (FIG. 14A).

  A double-sided tape (not shown) is adhered to the back surface (first main surface) of the Pradan 202 in FIG. 14B to form an adhesive layer and a release paper laminated on the adhesive layer (both not shown). ) Is formed. A plurality (five in this example) of handle units 136 (FIG. 10) are provided on the second main surface 202B of the Pradan 202. The manner in which the handle unit 136 is fixed to the second main surface 202B is the same as that of the removal tool 132, and a description thereof will be omitted.

  Next, the removal tool 204 for the Newell panel 19 will be described. As shown in FIG. 15B, the removal tool 204 has a Pradan 206 having a shape matching the exposed surface 19E of the Newell panel 19 (FIG. 15A).

  By bonding a double-sided tape (not shown) to the back surface (first main surface) of the Pradan 206 in FIG. 15B, a pressure-sensitive adhesive layer and a release paper laminated on the pressure-sensitive adhesive layer (both not shown) ) Is formed. A plurality (four in this example) of handle units 136 (FIG. 10) are provided on the second main surface 206 </ b> B of the Pradan 206. The manner in which the handle unit 136 is fixed to the second main surface 206B is the same as that of the removal tool 132, and a description thereof will be omitted.

  Also, the procedure for removing the Newell panels 17 and 19 using the removal tools 200 and 204 is the same as that of the removal tool 132, and a description thereof will be omitted.

  The removal tool is completed (assembled) on site. In other words, in a storage where maintenance tools and the like near the site where the escalator 10 is installed are stored, a prdan (a state in which an adhesive layer is formed and release paper is laminated) and a handle unit are separately stored. . Then, when it becomes necessary to replace the balustrade panel, a paldan for the balustrade panel is selected, and a handle unit (one or a plurality) is adhered and fixed to this, thereby completing the balustrade panel removal tool. To use. In a state where the handle unit is fixed, that is, in a state in which the Pradan (in which the adhesive layer is formed and the release paper is laminated) and the handle unit are separately stored, rather than storing in a state of a balustrade panel removal tool, This is because the storage space can be reduced.

  As described above, the shape of the platen, which is a plate member constituting the removal tool, differs depending on the shape of the balustrade panel to be removed. The balustrade panel has various shapes other than those described above. The shape of each balustrade panel forming the escalator is mainly determined by whether the above-mentioned divided construction of the balustrade panel in the escalator is the vertical split or the vertical split, and whether the horizontal step is 1.5 or 3 sheets, or the like. Although illustrations of balustrade panel removal tools other than the balustrade panel described above are omitted, in any case, the removal tool 132 (FIG. 8), the removal tool 200 (FIG. 14B), and the removal tool 204 ( It can be configured under the same idea as in FIG.

  If there is a balustrade panel adjacent to one or both sides of the balustrade panel to be removed, the balustrade panel is made to correspond to the adjacent balustrade panel, and a stopper portion 154SP and a stopper portion as shown in FIGS. 158SP or stopper portions 162 and 164 may be provided.

  As mentioned above, although the balustrade panel removal tool which concerns on this invention was demonstrated based on embodiment, it is needless to say that this invention is not limited to the said form, For example, it can also take the following forms.

  (1) In the above-described embodiment, the shape of the pladan constituting the removal tool is adapted to (the exposed surfaces 17E, 18E, and 19E of) the balustrade panel. However, the shape of the pradadan is not necessarily limited to this shape.

  Not limited to the shape of the balustrade panel, for example, a disc shape, an elliptical plate shape, or a polygonal plate shape having an area smaller than the exposed surfaces 17E, 18E, and 19E of the balustrade panel but having a considerably large area. I do not care.

  That is, the removal tool has an arbitrary shape, but an adhesive layer is formed on one surface (first main surface) of the prada having a considerably large area, and a handle is provided on the other one surface (second main surface) side. It may be configured.

  Here, the considerably large area means that the first main surface is adhered to the tempered glass sheet constituting the balustrade panel, and the handle provided on the second main surface side (holding the handle). This is the area where the adhesive strength sufficient to suspend the balustrade panel is obtained. In this case, when a plurality of removal tools are used (when a plurality of removal tools are used for one balustrade panel), the sum of the adhesive strengths of the plurality of removal tools is sufficient to suspend the balustrade panel. Just do it.

  (2) The plate member constituting the removal tool is not limited to Pradan, and may be, for example, a wooden veneer plate or a reinforced cardboard made of paper.

  (3) In the above embodiment, the handle unit 136 is constituted by the plurality of handles 146, but the number of handles constituting the handle unit may be one.
