Description

  The present invention relates to an escalator, and more particularly, to a balustrade structure and the like.

  In the escalator, balustrades having a plurality of balustrade panels arranged along the running path of the steps are installed on both sides of the steps that are connected in a circular manner and circulate.

  Of the plurality of balustrade panels, the balustrade panels positioned at both ends in the line-up direction have arc-shaped portions that match the trajectory of the moving handrail that travels in an inverted manner while drawing an arc. Hereinafter, in a plurality of balustrade panels, when the balustrade panel located at both ends and the balustrade panel located between the two are distinguished from each other, the balustrade panels located at both ends will be referred to as “new el panels” and the balustrade panels other than the new el panel The panel will be referred to as an “intermediate panel”.

  As these balustrade panels, those made of glass are often used in recent years, with an emphasis on design. A balustrade panel made of glass has a scattering prevention film attached to one side of a reinforced plate glass.

  As for each balustrade panel, the lower end part is being fixed and installed in the truss as described in patent document 1 or patent document 2, for example. The escalator described in Patent Documents 1 and 2 has a groove having a U-shaped cross section, and has a panel holding member fixed to the truss. The panel holding member is fixed to the truss so that the longitudinal direction of the groove is parallel to the traveling direction of the steps.

  A female screw is formed in the thickness direction on the side wall (hereinafter referred to as “first side wall”) on the side close to the step among the both side walls of the groove. A bolt is screwed into the female screw from the outside of the groove, and a clamping piece is applied to the tip of the bolt.

  The lower end portion of the balustrade panel is inserted from above the groove between the side wall (hereinafter referred to as “second side wall”) of the both side walls of the groove and far from the step and the sandwiching piece. In this state, by tightening the bolt, the lower end portion is sandwiched between the second side wall and the sandwiching piece, and the balustrade panel is fixed to the truss in an upright posture.

  As described in Patent Document 3 and Patent Document 4, for example, a plurality of guide rails that guide the moving handrail are fixed to the upper edge of the plurality of intermediate panels fixed in this manner. Yes.

  For the guide rails described in Patent Documents 3 and 4, an extruded aluminum material is used. A pair of flange portions projecting on both sides in the width direction are formed at the upper end portion of the guide rail. Between the two flange portions, an upper groove is formed that opens upward and extends along the length direction. Below the upper groove, a lower groove is formed that opens downward and extends along the length direction. Further, a screw insertion hole penetrating between the bottom surface of the upper groove and the ceiling surface of the lower groove is formed.

  One side surface of the lower groove is formed as a vertical surface, and the other side surface is formed as a slope that is further away from the vertical surface as it goes downward. A wedge member having a trapezoidal cross section is provided in the lower groove. In the wedge member, the side surface facing the inclined surface is formed in a plane parallel to the inclined surface, and the side surface opposite to the inclined surface is formed in a surface parallel to the vertical surface. The wedge member is formed with a female screw penetrating vertically. The female screw is screwed into the screw insertion hole from the upper groove side.

  The upper edge portion of the intermediate panel is fitted between the wedge member and the vertical surface, and the wedge member is pulled up by tightening the screw. As a result, due to the wedge effect, the side surface of the upper edge portion of the intermediate panel is firmly held by the wedge member and the vertical surface, and the guide rail is fixed to the intermediate panel. On the guide rail fixed to the intermediate panel, a moving handrail is attached to both flange portions so as to close the upper groove between the both flange portions.

  In addition, when an accessory such as a lighting fixture is attached to the intermediate panel, an attachment member to which the accessory is attached is fixed to an upper end edge of the intermediate panel (for example, FIG. 6).

  For example, an aluminum extruded shape is also used for the attachment member. The fixing structure of the mounting member is similar to the fixing structure of the panel holding member. In other words, the mounting member has a U-shaped cross section, and the upper edge of the balustrade panel is fitted in a groove opened downward. A female thread that penetrates in the thickness direction is formed on one side wall of the groove, and a bolt is screwed into the female thread from the outside of the groove. A clamping piece is applied to the tip of the bolt. By tightening the bolt, the upper edge of the intermediate panel is firmly held between the holding piece and the other side wall, and the mounting member is fixed to the intermediate panel.

  Although not explicitly described in Patent Documents 2, 3, and 4, the arcuate edge of the Newell panel has an attachment member or guide rail that is curved into a shape that matches the arc shape. It is thought that it is fixed in the same way as.

  By the way, the balustrade panel described above is replaced with a new one when the tempered plate glass is broken or the scattering prevention film is deteriorated over time. This replacement work is performed by stopping the escalator operation. For example, in the case of an escalator installed in a commercial facility, particularly when a tempered plate glass is damaged during operation, a particularly prompt replacement is required. .

  When removing the intermediate panel at the time of the replacement, first, it is necessary to release the fixing of the guide rail and the mounting member fixed to the upper edge of the intermediate panel. The guide rail is unlocked by loosening the screw screwed to the wedge member, and the mounting member is fixed by loosening the bolt screwed to the female screw formed on one side wall of the groove. Canceled. When the fixing is released, the upper edge of the intermediate panel is fitted in the lower groove of the guide rail or the groove of the mounting member with play in the thickness direction of the intermediate panel.

  However, in the attachment structure of the lower end portion of the intermediate panel in the conventional escalator described in Patent Documents 1 and 2, the intermediate panel needs to be finally removed by removing the lower end portion above the holding member. The operation | work which extracts the said guide rail or the said attachment member in which the upper end edge part of the object intermediate panel is fitted upwards from the said intermediate panel is needed.

  For this reason, considerable time is required for the replacement work of the balustrade panel (intermediate panel).

  Therefore, the inventor of the present application, as a fixing device for fixing the balustrade panel to the truss at its lower end, in a state where the fixing of the balustrade panel is released, the front of the traveling road side of the lower end is opened. An escalator with a fixed fixture was created and filed earlier.

  According to this, the fixing of the guide rail or mounting member, which is a fixed member provided at the upper end portion of the intermediate panel, to the intermediate panel is released, and the upper end edge of the intermediate panel is attached to the fixed member. If it is in a state where it is fitted with play in the thickness direction, the intermediate panel is moved from the object to be fixed and the fixture by moving the lower end portion of the intermediate panel downward and then moving it downward. Can be removed.

  Therefore, in order to replace the intermediate panel, a fixing device that is forced to extract the guide rail or the mounting member, which is a fixed member fitted to the upper edge of the intermediate panel to be replaced, from the intermediate panel upward. Compared with the above-described conventional escalator, the time required for replacing the intermediate panel can be shortened as much as possible.

  The bolt 62 provided in the mounting member 30 and the insertion holes 54G and 54H provided in the wedge member 54 are used when the fastening member 60 is loosened when the fastening screw 60 is tightened and as will be described later. It functions as a restricting means that restricts rotation around the heart.

  When the tightening screw 60 is turned, the wedge member 54 into which the tightening screw 60 is screwed tries to rotate around the axis of the tightening screw 60 due to the frictional force generated between the tightening screw 60 and the wedge member 54. In this case, if no care is taken, both ends of the wedge member 54 may collide with surrounding members, possibly damaging the member.

  Therefore, the bolt 62 is brought into contact with the inner walls of the insertion holes 54G and 54H just before rotating until it hits a surrounding member, thereby restricting further rotation.

  The bar member used as the regulating means is not limited to the bolt 62, and for example, a pin may be used.

  The fixing of the attachment member 30 to the balustrade panel 13 is released by loosening the fastening screw 60. When the tightening screw 60 is loosened, the tightening screw 60 is screwed downward. As a result, the pressing force with which the fastening screw 60 (the head thereof) presses the wedge member 54 against the second wall surface 46B is eliminated, and consequently the wedge member 54 presses toward the second main surface 13B of the balustrade panel 13. The pressing force is canceled. As a result, the wedge member 54 can be pulled down by hand.

  When pulled down, as shown in FIG. 6A, the wedge member 54 falls until its lower surface 54 </ b> C comes into contact with the flat washer 56. However, if the tightening screw 60 is removed from the female screw 30 </ b> A, the wedge member 54 is also removed from the mounting member 30.

  By the way, depending on the manner in which the wedge member 54 bites into the protective member 48, even if the fastening screw 60 is loosened, the wedge member 54 may not be pulled down by hand alone. In this case, if the left and right side surfaces (both end surfaces in a direction perpendicular to the paper surface) of the wedge member 54 are hit with a metal rod or the like, the wedge member 54 is loosened by the impact, and the wedge member 54 cannot be dropped. However, it is not a reliable method.

  Therefore, in this case, the loosening screw 64 is used in the present embodiment. A method using the loosening screw 64 will be described with reference to FIG. 7 is a cross-sectional view including a transverse section of the wedge member 54 cut along a plane including the axis of the female screw 54E (FIG. 4) of the wedge member 54. As shown in FIG.

  In the state where the tightening screw 60 (FIG. 3A) is loosened, the loosening screw 64 is screwed into the lower opening of the female screw 54E. As the loosening screw 64, for example, a relatively long hexagon socket head bolt as shown in the figure is used.

  When the loosening screw 64 is screwed in, the loosening screw 64 is screwed upward, and its tip abuts against the second wall surface 46B of the mounting member 30. If the loosening screw 64 is screwed in even after the contact, the loosening screw 64 cannot be screwed any further, so that a force is exerted to make the wedge member 54 screw relatively downward. As a result, the wedge member 54 moves downward. Thus, when the wedge member 54 is loosened, the wedge member 54 is removed from the mounting member 30 with the loosening screw 64 screwed in when the tightening screw 60 is detached from the female screw 30A.

  The loosening screw 64 is not always screwed to the wedge member 54 and is used only when removing the balustrade panel 13.

  Moreover, in the said embodiment, although the hexagon socket head cap screw was used as the fastening screw 60 and the loosening screw 64, not only this but a hexagon head bolt may be used. Alternatively, a cross-recessed screw may be used.

  As described above, in the wedge member 54 provided between the second wall surface 46B of the groove 46 fitted in the upper edge of the balustrade panel 13 and the second main surface 13B of the balustrade panel 13, the depth of the groove 46 is increased. Inserted into the screw insertion hole 54D penetrating in the vertical direction (the vertical direction in this example) from the opening side (the lower side in this example) of the groove portion 46 and screwed into the female screw 30A formed on the mounting member 30. When the tightening screw 60 is loosened, the fixing of the attachment member 30 to the upper edge of the balustrade panel 13 is released. That is, since the fixing of the mounting member 30 can be released from the lower side with respect to the mounting member 30, it is not necessary to remove the member (the guide rail 44 in this example) mounted on the upper side of the mounting member 30. .

  When the fixing of the attachment member 30 is released, the upper edge of the balustrade panel 13 is fitted in the groove 46 of the attachment member 30 with play in the thickness direction of the balustrade panel 13. In this case, as will be described later, if the lower end of the balustrade panel 13 is released and the front of the step 12 on the road RW side of the step 12 is opened, the balustrade panel 13 is Can be removed.

  The fixing device 26 having such a fixing structure will be described. As shown in FIG. 8, the fixing device 26 includes a fixed bracket 66 and a movable bracket 68.

Locking nuts 108 and 110 are screwed onto the height adjusting bolts 104 and 106.

  Cushion pads 112 and 114, which are cushion members made of an elastic member such as a flat rubber, are attached to both ends of the upper surface of the lower end portion 70A of the receiving member 70.

  Returning to FIG. 8, the movable bracket 68 includes a facing member 72 and a plurality of (four in this example) rotating arms 132, 134, 136, and 138 described later.

  In this example, an L-shaped steel (unequal angle mountain shaped steel) is used for the facing member 72.

  A plurality of female screws (not shown) penetrating in the thickness direction are formed in the long side portion 72A of the facing member 72. Each of the female screws has a pressure contact bolt 116, 118, 120, which is a pressure contact member. 122 is screwed. Further, loosening nuts 124, 126, 128, and 130 are screwed into the pressure contact bolts 116, 118, 120, and 122, respectively.

  In addition, rotating arms 132, 134, 136, and 138 are joined to the facing member 72 so as to correspond to the restricting members 92, 94, 96, and 98, respectively. Each of the rotating arms 132, 134, 136, and 138 has a substantially square bar shape, and is welded to the facing member 72 (for example, fillet) with the half of the entire length superimposed on the long side portion 72A of the facing member 72. (Welding bead is not shown).

  Shaft holes 132A, 134A, 136A, and 138A are formed in the end portions of the rotating arms 132, 134, 136, and 138 on the side opposite to the joint portion with the facing member 72. The four shaft holes 132A, 134A, 136A, 138A are formed on the same axis. The shaft holes 132A, 134A, 136A, 138A have the same diameter as the shaft holes 84C, 86C, 88C, 90C of the shaft support members 84, 86, 88, 90.

  In each of the rotating arms 132, 134, 136, and 138, in the vicinity of the shaft holes 132A, 134A, 136A, and 138A, as will be described later, a contact surface 132B that contacts the restriction surfaces 92C, 94C, 96C, and 98C. 134B, 136B, and 138B are formed.

  The first shaft 140 is loosely inserted into the shaft holes 84C and 86C of the shaft support members 84 and 86 and the shaft holes 132A and 134A of the rotating arms 132 and 134, and the shaft holes 88C and 88C of the shaft support members 88 and 90 are inserted. The second shaft 142 is loosely inserted into the shaft holes 136A and 138A of the 90C and the rotating arms 136 and 138. E-type retaining rings 144 and 146 are provided at both ends of the first shaft 140 and the second shaft 142 (both E-type retaining rings on one end side appear in the figure). Not.) As shown in FIG. 9, the first shaft 140 and the second shaft 142 are provided below the lower edge of the balustrade panel 13 and in parallel with the lower edge as shown in FIG. 8A. .

  With the above-described configuration, the movable bracket 68 is connected to the fixed bracket 66 by the first and second shafts 140 and 142 so that the movable bracket 68 can rotate around its axis and slide in the direction of the axis. Has been. In this example, the movable bracket 68 and the fixed bracket 66 are connected by two shafts (first and second shafts 140 and 142). However, the present invention is not limited to this and may be connected by one shaft. Absent. That is, the shaft holes 84C, 86C, 88C, 90C provided in the shaft support members 84, 86, 88, 90 and the shaft holes 132A, 134A, 136A, 138A provided in the rotating arms 132, 134, 136, 138 are provided. The movable bracket 68 and the fixed bracket 66 may be connected by loosely inserting one shaft in all.

  The movable bracket 68 is slidable with respect to the fixed bracket 66 at least between a first position shown in FIG. 8A and a second position shown in FIG.

  The first positions are the rotating arms 132, 134, and 136 joined to the opposing member 72 on the regulating surfaces 92C, 94C, 96C, and 98C of the regulating members 92, 94, 96, and 98 joined to the receiving member 70, respectively. , 138 of the contact surfaces 132B, 134B, 136B, 138B (FIG. 10) are opposed to each other.

  In the second position, the movable bracket 68 slides in the axial direction of the first and second shafts 140 and 142 and in the direction of arrow C from the first position (FIG. 8A) with respect to the fixed bracket 66. As shown in FIG. 8B, the contact surfaces 132B, 134B, 136B, and 138B are positions that do not face the restricting surfaces 92C, 94C, 96C, and 98C, respectively.

  In the first position, as shown in FIG. 9, the contact surface 132 </ b> B, which is a part of the movable bracket 68, is part of the fixed bracket 66 within a virtual plane (not shown) orthogonal to the axis of the first shaft 140. It is in contact with the restriction surface 92C, which is a part, and the clockwise rotation around the first shaft 140 of the movable bracket 68 is restricted. The remaining contact surfaces 134B, 136B, and 138B are also in contact with the corresponding restricting surfaces 134B, 136B, and 138B, and this also restricts the rotation of the movable bracket 68.

  The fixing device 26 fixes the balustrade panel 13 to the truss 28 with the movable bracket 68 in the first position.

  As shown in FIGS. 2 and 9, a cushion sheet 148, which is an elastic member made of rubber or the like, is formed between the lower end of the balustrade panel 13 and the receiving surface 70 </ b> D of the receiving member 70 of the fixing bracket 66. It is sandwiched. The main surface of the cushion sheet 148 has the same shape as the receiving surface 70D, and is attached to the receiving surface 70D in a state of being superimposed on the receiving surface 70D.

  A pressure contact plate 150 is sandwiched between the lower end of the balustrade panel 13 and the tip of the pressure contact bolts 116, 118, 120, 122 (only two are shown in FIGS. 2 and 9). The pressure contact plate 150 is a plate body having a two-layer structure in which a rectangular steel sheet and a rubber sheet having the same rectangular shape are bonded together (the two-layer structure is not shown in the figure), and the balustrade panel 13 side. It is sandwiched in a form to which a rubber sheet is applied.

  A part of the lower end surface of the balustrade panel 13 is in contact with the upper surface of the cushion pads 112 and 114 (only the cushion pad 112 appears in FIGS. 2 and 9) or the tips of the height adjusting bolts 104 and 106 ( In this example, the lower end surface is in contact with the tips of the height adjustment bolts 104 and 106.) The lower end surface is supported by the receiving member 70 of the movable bracket 68 via the cushion pads 112 and 114 or the height adjustment bolts 104 and 106. It is supported by the lower end portion 70A which is a portion.

  The height adjusting bolts 104 and 106 are used in the following cases. When the balustrade panel 13 is placed on the cushion pads 112 and 114 and the height of the balustrade panel 13 is insufficient, the height adjustment bolts 104 and 106 are screwed upward, and the leading ends thereof are below the balustrade panel 13. The height of the balustrade panel 13 is adjusted by lifting it against the end face.

  In the state shown in FIG. 2 and FIG. 9, the pressure contact bolts 116, 118, 120, and 122 screwed (attached) into the female screw (not shown) of the facing member 72 facing the receiving surface 70D (FIG. 8A). ) Is strongly tightened and the balustrade panel 13 is fixedly held to the truss 28 at the lower end by pressing the lower end of the balustrade panel 13 toward the receiving surface 70D via the pressure plate 150. Has been. The movable bracket 68 is not slidable with respect to the fixed bracket 66 by tightening the pressure contact bolts 116, 118, 120, and 122. In order to prevent the press-contact bolts 116, 118, 120, 122 from loosening, the loosening nuts 124, 126, 128, 130 (FIG. 8A) are tightened.

  As described above, the skirt guard 152 is erected between the fixing device 26 that supports the balustrade panel 13 and the step 12, with a slight gap from the step 12, and the upper end of the skirt guard 152 and the balustrade panel 13 is provided with an inner deck (not shown) that covers the lower part and the fixing device 26. Further, although an outer deck is provided on the opposite side of the traveling road RW across the balustrade panel 13, the illustration of the outer deck is also omitted. The inner deck and the outer deck (both not shown) are made of, for example, a stainless steel plate, and a plurality of sheets are continuously provided along the traveling path RW.

  The balustrade panel 13 is fixed by the fixing device 26 as follows.

  First, after loosening the locking nuts 124, 126, 128, 130 (FIG. 8A), the press contact bolts 116, 118, 120, 122 (FIG. 8A) are loosened. As a result, the movable bracket 68 can slide in the axial direction of the first and second shafts 140 and 142.

  The movable bracket 68 is slid in the direction of arrow C to the second position shown in FIG. Next, the opposing member 72 is rotated in a direction away from the receiving surface 70D to obtain the state shown in FIGS. That is, the traveling road RW side front (direction shown by the arrow F in FIG. 11) of the lower end part of the balustrade panel 13 is opened.

  The fixing of the attachment member 30 at the upper edge of the balustrade panel 13 is released, and the upper edge of the balustrade panel 13 is fitted in the groove 46 of the attachment member 30 with play in the thickness direction of the balustrade panel 13. Then, as shown above, as shown by the alternate long and short dash line in FIG. 11, the balustrade panel 13 can swing the lower part thereof toward the road RW (the whole is inclined in the direction of the arrow S to have an oblique posture. Can do.) By moving the balustrade panel 13 downward in parallel with the main surface in a state where the lower part is swung to the traveling path RW side, the upper edge of the balustrade panel 13 is completely removed from the mounting member 30, and the balustrade panel 13 is fixed. 26 and the attachment member 30 will be removed. When the balustrade panel 13 is attached and removed, the inner deck (not shown) and the skirt guard 152 (FIGS. 2 and 9) corresponding to the balustrade panel 13 to be attached / removed are removed in advance.

  As is clear from the above description, according to the escalator 10 according to the first embodiment, the balustrade panel 13 can be removed without removing the mounting member 30 that is a fixed member at the upper edge of the balustrade panel 13 above the balustrade panel 13. It can be removed from the attachment member 30 and the fixture 26.

  As described above, the attachment member 30 from which the balustrade panel 13 is removed is connected to the attachment member adjacent thereto by the frame 40, and the adjacent attachment member is supported by the corresponding balustrade panel. Therefore, the attachment member 30 from which the balustrade panel 13 is removed does not fall off.

  According to the above-described fixing structure of the attachment member 30 to the upper edge of the balustrade panel and the above-described configuration of the fixing device 26, when any one of the intermediate panels 13, ..., 29 needs to be replaced The intermediate panel to be replaced can be removed independently.

  However, each of the Newell panels 11 and 31 cannot be removed independently. The reason will be described again with reference to FIG. FIG. 12C shows a state seen from the travel path RW side (FIGS. 1 and 2) of the step 12 with the inner deck and the skirt guard 152 (FIG. 2) removed. In FIG. 12C, the fixing device 26 is simplified and the frame 40 (FIG. 2) is omitted (the same applies to FIGS. 13, 14, and 15A). The fixing devices 26 are distinguished from each other by adding an alphabet.

  As shown in FIG. 12A, the Newell panel 11 has a rectangular portion 11C and a semicircular portion 11D. The arcuate edge portion 11E in the semicircular portion 11D projects in the horizontal direction in the state where the Newell panel 11 is installed (FIG. 12 (c)).

  As shown in FIG. 12C, the Newell panel 11 is fixed to a truss (not shown) by a fixing tool 26A at the lower end of the rectangular portion 11C.

  The attachment member 30 is fixed to a part of the upper edge of the rectangular portion 11C, and the attachment member 154 is fixed to the remaining portion of the upper edge and the arcuate edge 11E. The mounting member 154 is obtained by bending an extruded profile having the same cross section as the mounting member 30 in accordance with the outer peripheral shape of the Newell panel 11. Since the mounting member 154 has the same cross-sectional shape as the mounting member 30, hereinafter, in the description of the mounting member 154, the drawings used for the description of the mounting member 30 will be referred to.

  In the arcuate edge 11E, the attachment member 154 is fixed by a wedge member 54 (FIG. 4) at the positions indicated by arrows B1 to B8. The mounting member 154 portion corresponding to the arcuate edge 11E is similarly curved in an arc shape, while the wedge member 54 is in a straight bar shape, but the curvature radius of the curved portion is large, so this The attachment member 154 can be fixed without any problem using the wedge member 54.

  Note that the lighting fixture 32 is not attached to the section of the attachment member 154 that is curved in an arc shape. In this section, a cover (not shown) for closing the opening is provided in the opening portion of the frame 40 where the lighting fixture 32 is to be provided. A part of the lower end of the mounting member 154 is supported by a substrate (not shown) fixed to a truss (not shown).

  In order to remove the Newell panel 11 supported by the fixing device 26A and to which the mounting member 154 is fixed, the fixation by the fixing device 26A is released, and the wedge member 54 at a position indicated by arrows B1 to B8 (not shown in the drawing). ) Including all the wedge members 54 are removed.

  As a result, in the Newell panel 11, the front end of the Newell panel 11 is opened while the front of the traveling path RW side (the front side in FIG. 12C) of the lower end portion provided with the fixing device 26 </ b> A is opened. The edge portion and the arcuate edge portion 11E are fitted in the groove portions 46 of the attachment member 30 and the attachment member 154 with play in the thickness direction of the Newell panel 11.

  However, in this state, even if the lower part of the Newell panel 11 is swung to the traveling path RW side (the front side in the drawing), the mounting member in which the arcuate edge 11E (particularly, the lower half of the arcuate edge 11E) is fitted. Since the second wall surface 46B (FIG. 6) of the groove portion 154 becomes an obstacle and cannot be shaken, the Newell panel 11 cannot be removed.

  Therefore, in the present embodiment, the configuration (shape) of the balustrade panel is devised, and the removal of the New L panel is facilitated by the removal method described below.

  A balustrade panel 13 adjacent to the Newell panel 11 (hereinafter, referred to as “adjacent balustrade panel 13” when distinguished from other balustrade panels) runs horizontally with a curved portion 13C corresponding to a section where the moving handrail 20 curves. It comprised with the straight part 13D corresponding to the area to do. The length D1 in the horizontal direction of the straight portion 13D will be described later.

  The adjacent balustrade panel 13 is supported at its lower end by fixing devices 26B and 26C. An attachment member 30 is fixed to the upper edge of the adjacent balustrade panel 13. The adjacent balustrade panel 13 is installed with a gap of a distance D2 from the New L panel 11.

  The removal / attachment method (exchange method) of the New L panel 11 in the above configuration will be described.

(I) Adjacent balustrade panel fixing release step Release the fixation of the adjacent balustrade panel 13 by the fixtures 26B and 26C (FIG. 13 (a)), and the attachment member 30 fixed to the upper edge of the adjacent balustrade panel 13 Unpin.

(Ii) Adjacent railing panel removal step The adjacent balustrade panel 13 is removed (FIGS. 10 and 11). FIG. 13B shows a state where the adjacent balustrade panel 13 is removed.

(Iii) Newel panel fixation release step Releases the fixation of the Newell panel 11 by the fixing device 26A (FIG. 13B) and releases the fixation of the attachment member 30 and the attachment member 154 fixed to the Newell panel 11.

(Iv) New L panel slide step The New L panel 11 is slid in the direction of the arrow HL shown in FIG. That is, it is slid in the horizontal direction to the area where the removed balustrade panel 13 has been removed. The state after the slide is completed is shown in FIG.

  The Newell panel 11 is in a state of being placed on the lower end portions 70A (FIG. 10) of both the fixture 26A and the fixture 26B. Further, the arc-shaped edge portion 11E of the Newell panel 11 protrudes from the groove portion 46 (FIG. 6 and the like) of the arc-shaped portion of the mounting member 154. Therefore, in this state, the lower portion of the Newell panel 11 can be swung to the traveling path RW side (the front side in the drawing) without obstructing the second wall surface 46B (FIG. 6) portion of the groove 46.

  Conventionally, in general, the end balustrade panel is configured by a single panel over a curved area in which a moving handrail moves in a horizontal direction from an area in which the traveling direction changes in an arcuate path and changes its traveling direction. . If a conventional general edge balustrade panel having such a shape is adopted, even if the fixing by the fixing device 26 is released and the fixing of the attachment members 30 and 154 is released, the end balustrade panel has room for sliding. Absent. Therefore, in the end, in order to remove the end balustrade panel, it is necessary to remove the attachment members 30 and 154 from the end balustrade panel.

  Therefore, in the present embodiment, the conventional ordinary edge balustrade panel is divided into the New El panel 11 and the adjacent balustrade panel 13 in the region where the moving handrail 20 runs horizontally. 12 (c) has a length D [= (D1 + D2)], after removing the adjacent balustrade panel 13, at least the arc-shaped edge portion 11E of the Newell panel 11 can come out of the groove portion 46 of the mounting member 154. D1 and D2 are set so as to have a length that allows horizontal sliding for a distance.

(V) New-el panel removal step The new-el panel 11 in the state shown in FIG. 14A (slid state) is removed in the same manner as the adjacent balustrade panel 13. This completes the removal of the New L panel 11 (FIG. 14B).

  As described above, after the adjacent balustrade panel 13 is removed and the Newell panel 11 is slid as described above, the Newell panel 11 can be removed in the same manner as the adjacent balustrade panel 13. Thereby, since the operation | work which removes the attachment member 154 from the Newell panel 11 for the removal of the Newell panel 11 becomes unnecessary, a Newel panel can be removed efficiently compared with the past.

  Note that the execution order of the plurality of steps may be changed as appropriate. For example, after executing step (i) and step (iii), step (ii) may be executed.

  As will be described below, the new Newell panel 11 is attached in the reverse order of the above-described removal.

(Vi) New El panel mounting step The New El panel 11 is tilted to the opposite side of the travel path RW, and the upper edge thereof is inserted into the groove 46 (FIG. 6) of the mounting members 30, 154, and the lower end is fixed to the fixing device 26A. It shakes toward 26B and it mounts on the lower end part 70A (FIG. 10) of fixing tool 26A, 26B (FIG. 14 (a)).

(Vii) New L Panel Slide Step The New L panel 11 is slid in the direction of the arrow HR shown in FIG. 14A, and the arcuate edge 11E is fitted into the groove 46 (FIG. 6) of the mounting member 154.

(Viii) New el panel fixing step The lower end of the new el panel 11 is fixed by the fixing device 26A (FIG. 13 (a)). Further, the mounting members 30 and 154 are fixed to the Newell panel 11 by a plurality of wedge members 54 (not shown).

(Ix) Adjacent balustrade panel placement step After the upper edge of the adjacent balustrade panel 13 is inserted into the groove 46 (FIG. 6) of the mounting member 30, it is placed on the lower end 70A (FIG. 10) of the fixtures 26B and 26C. (FIG. 13A).

(X) Adjacent balustrade panel fixing step The lower end portion of the adjacent balustrade panel 13 is fixed by the fixtures 26B and 26C (FIG. 12B). Further, the attachment member 30 is fixed to the adjacent balustrade panel 13 by a plurality of wedge members 54.
The New L panel is replaced by the above procedure.

  In addition, you may change suitably the execution order of said several step at the time of attaching the new New L panel 11. FIG. For example, the (viii) step and the (x) step may be executed after executing the (vi) step, the (vii) step, and the (ix) step.

(Modification)
In the said embodiment, although the adjacent balustrade panel 13 adjacent to the New El panel 11 was made into the panel shape which has the curved part 13C and the straight part 13D, the shape of the balustrade panel adjacent to the New El panel 11 is not restricted to this.

  For example, as shown in FIG. 15B, a rectangular balustrade panel 33 (hereinafter also referred to as “adjacent balustrade panel 33”) may be used. As shown in FIG. 15A, the adjacent balustrade panel 33 has a rectangular shape that is long in the vertical direction and has a width L1.

  The adjacent balustrade panel 33 is supported at the lower end by a fixture 26B. A mounting member 30 is fixed to the upper edge of the adjacent balustrade panel 33. The adjacent balustrade panel 33 is installed with a gap of a distance L2 from the New L panel 11.

  The balustrade panel 35 adjacent to the adjacent balustrade panel 33 on the side opposite to the Newell panel 11 side is supported at the lower end by fixing devices 26B and 26C. The balustrade panel 35 is installed with a gap of a distance L3 from the adjacent balustrade panel 33.

  The adjacent balustrade panel 33 can be removed in the same manner as the adjacent balustrade panel 13 of the above embodiment by releasing the fixing by the fixing device 26B and releasing the fixing of the attachment member 30 fixed to the adjacent balustrade panel 33. it can.

  Then, the length L shown in FIG. 15A [= (L1 + L2 + L3)] is such that at least the arc-shaped edge 11E of the Newell panel 11 can come out of the groove 46 of the mounting member 154 after the adjacent balustrade panel 33 is removed. The lengths of L1, L2, and L3 are set so as to allow a length to slide in the horizontal direction corresponding to the distance.

  In addition, when the attachment member 30 part corresponding to the gap | interval of length L3 between the adjacent balustrade panel 33 and the balustrade panel 35 is curving, even if the adjacent balustrade panel 33 is removed, the New L panel 11 May not be able to enter the area. In this case, each of L1 and L2 is set so that (L1 + L2) is at least as long as the distance.

  Here, since the structure which makes the balustrade panel adjacent to the New L panel 11 a rectangle like the adjacent balustrade panel 33 is not seen conventionally, there exists a possibility that a passenger may lean an unnatural feeling. Therefore, by making the adjacent balustrade panel 33 different in color from other balustrade panels, it may be possible to give the passenger a sense that the design process is being actively performed. For this reason, it can be considered that the adjacent balustrade panel 33 is made of glass having a color or texture different from that of other balustrade panels. For example, while the balustrade panels other than the adjacent balustrade panel 33 are transparent, it is conceivable that the adjacent balustrade panel 33 is colored or ground glass. Alternatively, it is conceivable that the balustrade panel other than the adjacent balustrade panel 33 is made of glass, whereas the adjacent balustrade panel 33 is made of metal (for example, made of stainless steel).

  Furthermore, the adjacent balustrade panel adjacent to the Newell panel 11 is not limited to a rectangle, and may be formed in a trapezoidal shape. In this case, of the upper and lower sides (upper and lower bases) of the trapezoid, the length of the shorter side is in the horizontal direction as long as the arc-shaped edge of the Newell panel can escape from the groove 46 of the mounting member 154. It becomes the object when considering the length that allows the slide.

  In short, when the adjacent balustrade panel is removed from the fixtures 26B, 26C and the attachment member 30, the Newell panel is moved to the region where the removed adjacent balustrade panel exists, and at least its arc-shaped edge portion is the groove 46 of the attachment member 154. It suffices if the adjacent balustrade panel is formed in such a shape that it can be slid by the distance that can be removed.

  In the above embodiment, the configuration of the Newell panel 11 on the upper floor US side and the adjacent balustrade panel 13 has been described, but the Newell panel 31 on the lower floor DS side and the adjacent balustrade panel 29 (FIG. 1) adjacent thereto are also included. Since it can be configured based on the same idea as the Newell panel 11 and the adjacent balustrade panel 13, the description thereof will be omitted. Also, the balustrade panel adjacent to the Newell panel 31 may be a rectangle that is long in the vertical direction, as in the case of the above-described modification.

<Embodiment 2>
