Description

  The present invention relates to a passenger conveyor, and more particularly to a balustrade panel mounting structure.

  In passenger conveyors, for example, escalators, balustrades having a plurality of balustrade panels arranged in line along the running direction of the steps are installed on both sides of the steps that are connected in a circular manner and circulate. As the balustrade panel, a glass-made panel is 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.

  The balustrade panel is installed with its lower end fixed to a truss as described in, for example, Patent Document 1 and Patent Document 2. 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, the lower end is clamped by the second side wall and the clamping piece by tightening the bolt, and the balustrade panel is attached to the truss in an upright posture.

  As described in, for example, Patent Document 3 and Patent Document 4, a plurality of guide rails for guiding the moving handrail are fixed to the upper end portions of the plurality of balustrade panels attached in this way. . It should be noted that the number of balustrade panels and the number of guide rails existing thereon are not necessarily the same, and therefore the balustrade panels and the guide rails do not necessarily have a one-to-one correspondence.

  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 end portion of the balustrade 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 end portion of the balustrade panel is firmly held by the wedge member and the vertical surface, and the guide rail is fixed to the balustrade panel. On the guide rail fixed to the balustrade panel, a moving handrail is attached to the flange portions so as to close the upper groove between the flange portions.

Moreover, when accessories, such as a lighting fixture, are attached to a balustrade panel, the attachment member to which the said accessories were attached is being fixed to the upper end part of the balustrade panel (for example, FIG. 6 of patent document 2). See).
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. That is, the mounting member has a “U” shape in cross section, and the upper end 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. Then, by tightening the bolt, the upper end portion of the balustrade panel is firmly held between the holding piece and the other side wall, and the attachment member is fixed to the balustrade panel.

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 balustrade panel at the time of the replacement, first, it is necessary to release the fixing of the guide rail and the attachment member fixed to the upper end portion of the balustrade 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. In a state where the fixing is released, the guide rail and the mounting member are fitted to the upper end portion of the balustrade panel with play in the thickness direction of the balustrade panel.

However, in the mounting structure of the balustrade panel lower end portion in the conventional escalator described in Patent Documents 1 and 2, the balustrade 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 fitted to the upper end part of the target balustrade panel upwards from the said balustrade panel is needed.
For this reason, it takes a considerable amount of time to replace the balustrade panel.

In addition, the above-mentioned subject is common not only to the escalator which has a balustrade panel made of glass, but also to the escalator which has the balustrade panel comprised with materials other than glass.

Hereinafter, an embodiment of a passenger conveyor according to the present invention will be described by taking an escalator as an example with reference to the drawings. In FIGS. 2, 4 to 10, and 17, hatching indicating a cross section is omitted to avoid complexity.
<Embodiment 1>
As shown in FIG. 1, the escalator 10 according to the first embodiment includes a plurality of steps 12 that are endless transport bodies that are connected in a circular manner and circulate and transport passengers. The balustrades 14 and 16 are installed on both sides of the travel path RW of the step 12. Each of the balustrades 14 and 16 has a plurality of balustrade panels 18 erected along the travel path RW (in FIG. 1, the balustrade panel attaches a sign only to the balustrade panel 18 constituting the balustrade 14 on one side. ing.). The balustrade panel 18 is made of glass, for example, and is formed by sticking a scattering prevention film to one side of a tempered plate glass.

On the outer periphery of the balustrade panel 18 are provided handrails 20 and 22 each having an endless belt shape that is guided by a guide rail (not shown in FIG. 1) and circulates in the same direction as the step 12 at the same speed.
The escalator 10 is installed, for example, between a floor DS below the floor and a floor US above the floor in the building. The escalator 10 is used for ascending or descending when the direction of travel of the step 12 is switched, and a passenger on the step 12 moves from the floor US upstairs to the floor US upstairs or the floor US upstairs. It is transported to the lower floor DS.
When the escalator 10 is used for ascending, there is a moving handrail 22 on the right side in the traveling direction of the passenger conveyed by the step 12 and a ceiling DC portion (intersection) on the lower floor that is three-dimensionally adjacent to the moving handrail 22. A protective plate (fixed protective plate) 24 stipulated by laws is installed. The protection plate 24 is installed for the purpose of preventing an accident in which a part of the passenger's body is caught between the moving handrail 22 and the ceiling DC.

Next, the balustrades 14 and 16 will be described. The balustrade 14 and the balustrade 16 are symmetrically installed across the travel path RW, and basically have the same configuration. Therefore, the balustrade 14 will be described as a representative, and the description of the balustrade 16 will be omitted.
As shown in FIG. 2, each of the balustrade panels 18 constituting the balustrade 14 is attached to the truss 28 by a plurality of (for example, two) fixing devices 26 each having a lower end portion installed along the traveling path RW. It is fixed. Since the fixing device 26 has the same configuration, only one fixing device 26 will be described.

The fixing device 26 includes 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 as fastening members, and the fixing device 26 is attached to the truss 28. The fixing bracket 30 is fixed to the truss 28 with two sets of bolts 34B and nuts 34N, but only one bolt 34B and nut 34N appears in FIG.
An outer deck 40 is attached to the fixed bracket 30 by bolts and nuts 36. Further, a skirt guard 42 is erected with a slight gap from the step 12, and an inner deck that covers the lower part and the fixing device 26 is provided between the upper end part of the skirt guard 42 and the lower part of the balustrade panel 18. Although it is provided, the illustration of the inner deck is omitted. The inner deck (not shown) is made of, for example, a stainless steel plate, and a plurality of inner decks are continuously provided along the travel path RW.

Next, details of the fixing device 26 will be described with reference to FIG. As described above, the fixing device 26 includes the fixed bracket 30 and the movable bracket 32.
The fixing bracket 30 has a bolt insertion hole 44 through which the bolt 34B (FIG. 2) is inserted when fixing 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 a main surface portion opposite to the traveling path RW at the lower end portion of the balustrade panel 18 in a state where the balustrade panel 18 is fixedly held by the fixing device 26 as will be described later (FIG. 2). .

  The movable bracket 32 is pivotally supported with respect to the fixed bracket 30 by a shaft 48 so as to be swingable as will be described later. The shaft 48 is obtained by subjecting both ends of a cylindrical round bar to a so-called chamfering process. By this two-chamfering process, plate-like portions 48A having two parallel surfaces are formed at both ends of the shaft 48 (only one end is shown in FIG. 3 (d)). In the shaft 48, a cylindrical portion 48B other than the plate-like 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-like portion 48A is fixed. Projecting from both side surfaces 30 </ b> A of the bracket 30. Each of the holes (not shown) formed in the cylindrical portion 48B of the shaft 48 and the fixed bracket 30 is formed with a corresponding key groove (not shown), and the shaft 48 has the hole (not shown). On the other hand, the cylindrical portion 48B is attached to be non-rotatable by a parallel key (not shown).

The movable bracket 32 has a pair of arm portions 50 extending in the left direction at both ends in the vertical direction in FIG. At the tip of each of the arm portions 50, a saddle hole 52 (only one of them is shown in FIG. 3B) penetrating in the vertical direction is provided. The daruma hole 52 includes a circular portion 52A and a long hole portion 52B communicating with the circular portion 52A. The width of the long hole portion 52B is such that the plate-like portion 48A of the shaft 48 engages without rattling. The diameter of the circular portion 52 </ b> A is slightly larger than the cylindrical portion 48 </ b> B of the shaft 48.
Then, the plate-like portion 48 </ b> A of the shaft 48 is inserted into both the dart 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-like portion 48 </ b> A is engaged with the elongated hole portion 52 </ b> B of the barrel hole 52, the movable bracket 32 cannot swing around the axis of the shaft 48 with respect to the fixed bracket 30. It becomes. On the other hand, when the movable bracket 32 is pushed in the direction of the arrow A and the plate-like portion 48A enters the circular portion 52A of the dart hole 52, the movable bracket 32 can swing around the axis of the shaft 48.

Here, the state in which the plate-like portion 48A is engaged with the elongated hole portion 52B (enters the deep hole portion 52B) is said to be that the movable bracket 32 is in a “fixed state” with respect to the fixed bracket 30 and is plate-like. The state in which the portion 48A is removed from the elongated hole portion 52B and exists in the circular portion 52A is referred to as the movable bracket 32 being “movable” with respect to the fixed bracket 30.
The movable bracket 32 has 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 in a fixed state. The support portion 54 has a substantially rectangular plate shape. Both arm portions 50 described above are extended leftward from both ends in the vertical direction of the support portion 54 in FIG.

The movable bracket 32 rises vertically from the end of the support portion 54 opposite to the both arm portions 50 and has opposed portions 56 and 58 that face the receiving surface 46 of the fixed bracket 30 in a fixed state. In each of the opposing portions 56 and 58, the movable bracket 32 is fixed to the fixed bracket 30, and two female screws (four in total, both not shown) formed in a direction perpendicular to the receiving surface 46 of the fixed bracket. ) Are formed, and press-fitting bolts 60, 62, 64, 66 which are press-contact members are screwed into the respective female screws. Further, loosening prevention nuts 68, 70, 72, and 74 are screwed into the pressure contact bolts 60, 62, 64, and 66, respectively.
Cushion pads 76 and 78, which are cushion members made of an elastic member such as a flat rubber, are attached to the upper surface of the support portion 54 of the movable bracket 32.

Returning to FIG. 2, a cushion sheet 80 that is an elastic member made of rubber or the like having a rectangular shape is sandwiched between the lower end portion of the balustrade panel 18 and the receiving surface 46 of the fixed bracket 30. The cushion sheet 80 has the same main surface as the receiving surface 46, and is attached to the receiving surface 46 in a state of being superimposed on the receiving surface 46.
A pressure contact plate 82 is sandwiched between the lower end of the balustrade panel 18 and the tips of the pressure contact bolts 60, 62, 64, 66 (only two are shown in FIG. 2). The pressure contact plate 82 is a plate body having a two-layer structure in which a rectangular steel sheet and a rubber sheet having the same rectangle are bonded together (the two-layer structure is not shown in the figure), and the balustrade panel 18 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 18 is in contact with an upper surface of the cushion pads 76 and 78 (only the cushion pad 76 appears 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. The cushion pads 76 and 78 are not essential components and may be omitted. In that case, the balustrade panel 18 is supported by the support portion 54 with its lower end surface abutting on the support portion 54. Alternatively, instead of the cushion pads 76 and 78, as a constituent member of the balustrade panel 18, a cushion tape (not shown) having a width comparable to the thickness of the tempered plate glass may be attached to the lower end surface of the tempered plate glass. I do not care.
In the state shown in FIG. 2, the pressure contact bolts 60, 62, 64, 66 that are screwed into (attached to) the internal threads (not shown) of the facing portions 56, 58 facing the receiving surface 46 are tightened strongly. The balustrade panel 18 is fixedly held to the truss 28 at the lower end portion by pressing the lower end portion of the balustrade panel 18 toward the receiving surface 46 through the press contact plate 82. And in order to prevent the press-contact bolts 60, 62, 64, 66 from loosening, the loosening prevention nuts 68, 70, 72, 74 are tightened.

  A guide rail 86 is fitted and attached to the upper end of the balustrade panel 18 that is fixed and held from above through a rubber grip member 84. The guide rail 86 is produced, for example, by subjecting a stainless steel plate to sheet metal processing. The moving handrail 20 is wound around the guide rail 86, and the moving handrail 20 is guided by the guide rail 86 and circulates. A plurality of guide rails 86 are continuously provided along the upper end portions of the plurality of balustrade panels 18 erected along the traveling path RW, and the ends of the adjacent guide rails 86 are bolts, nuts, and the like. Are connected by a connecting member (not shown). It should be noted that the number of balustrade panels 18 and the number of guide rails 86 existing thereon are not necessarily the same, and therefore the balustrade panels 18 and the guide rails 86 have a one-to-one correspondence. Not exclusively.

The replacement procedure when the balustrade panel 18 is damaged in the balustrade 14 having the above configuration will be described below.
(I) First, one or a plurality of inner decks (not shown) corresponding to (being opposed to) the lower part of the damaged balustrade panel 18 are removed.
(Ii) Next, after loosening the locking nuts 68, 70, 72 and 74 (FIGS. 2 and 3), the pressure contact bolts 60, 62, 64 and 66 (FIGS. 2 and 3) are loosened, and The pressure contact bolts 60,..., 66 are screwed back to the traveling path RW side until their respective tips are immersed in the facing portions 56, 58 (FIGS. 2 and 3).

(Iii) Then, the pressure contact plate 82 is removed, the movable bracket 32 is pushed in the direction of arrow A in FIG. 2, and the plate-like portion 48A (FIG. 3 (d)) of the shaft 48 is circular in the round hole 52 (FIG. 3). It is located at the part 52A. That is, the movable bracket 32 is changed from the “fixed state” to the “movable state” with respect to the fixed bracket 30.
FIG. 4 shows a state where the operations (i) to (iii) have been completed.
(Iv) The movable bracket 32 in the movable state is swung around the shaft 48 in the direction of the arrow C (clockwise). That is, the movable bracket 32 is swung below the balustrade panel 18 around the shaft 48.
FIG. 5 shows a state of the fixing device 26 after the movable bracket 32 is swung.
(V) By swinging the movable bracket 32 as described above, the movable bracket 32 is moved from the posture (FIGS. 2 and 4) in which the facing portions 56 and 58 (FIG. 3) face the receiving surface 46. 56, 58 swing together with the pressure contact bolts 60,..., 66 below the balustrade panel 18 to open the lower end of the balustrade panel 18 in front of the traveling path RW (in the direction indicated by the arrow F) and to support it. The portion 54 is spaced downward from the lower end surface of the balustrade panel 18 so that the balustrade panel 18 is unlocked (FIG. 5).

(Vi) From the state shown in FIG. 5, the balustrade panel 18 is lowered in the direction of arrow D, that is, the upper end portion is pulled out from the guide rail 86 into which the upper end portion is fitted, and the lower portion is directed in the direction of arrow S. The balustrade panel 18 can be removed to the traveling road RW side.
As described above, the guide rail 86 from which the upper end portion of the balustrade panel 18 is pulled out is connected to the guide rail adjacent thereto by the connecting member (not shown) (it is still connected). Adjacent guide rails are supported by corresponding balustrade panels. Therefore, the guide rail 86 from which the upper end portion of the balustrade panel 18 is pulled out does not fall off.

A new balustrade panel 18 to replace the damaged balustrade panel 18 is attached by a procedure reverse to the above procedure.
That is, the lower part of the balustrade panel 18 is shaken in the direction opposite to the arrow S shown in FIG. 5, the balustrade panel 18 is brought directly under the guide rail 86, lifted up as it is, and the upper end portion is fitted into the guide rail 86.

In the guide rail 212, the moving handrail 20 is attached to both flange portions 212D and 212E.

A structure for fixing the attachment member 208 provided with the lighting fixture 104 and the guide rail 212 to the upper end portion of the balustrade panel 18 as described above will be described with reference to FIG. 11A is a view cut along a plane including an axis of a tightening screw 228 described later, and FIG. 11B is cut along a plane including an axis of a hexagon socket head bolt 230 described later. FIG.
As shown in FIG. 11, the attachment member 208 has a groove portion 214 opened downward, and the groove portion 214 is fitted into the upper end portion of the balustrade panel 18 from above.

  The first wall surface 214A of the groove 214 is formed in parallel to the first main surface 18A of the balustrade panel 18, and the second wall surface 214B facing the first wall surface 214A is connected to the second main surface 18B of the balustrade panel 18. Is formed on a surface that is inclined with respect to the second main surface 18B so that the distance therebetween becomes wider toward the lower side. Here, the second main surface 18B is the main surface on the side facing the travel path RW (FIG. 10).

A protective member 216 that protects the balustrade panel 18 is placed on the upper end of the balustrade panel 18. The protective member 216 includes a cushion rubber 218 made of a rubber extruded material having a substantially “U” -shaped cross section, and a thin plate-like metal having a substantially “U” -shaped cross section that is slightly larger than the cushion rubber 218. And a cover 220. For the metal cover 220, for example, stainless steel is used.
A wedge member 222 is provided between the second main surface 18B of the balustrade panel 18 and the second wall surface 214B of the groove portion 214. The wedge member 222 is made of a metal material (for example, stainless steel) or a hard synthetic resin.

As shown in FIG. 12, the wedge member 222 has a rod shape having a cross section that is generally a right triangle. A plurality of wedge members 222 are used with a distance from one mounting member 208.
In the state shown in FIG. 11, the wedge member 222 includes a pressing surface 222 </ b> A that faces the second main surface 18 </ b> B of the balustrade panel 18, and a slope 222 </ b> B along the second wall surface 214 </ b> B of the groove 214. The remaining surfaces other than the both side surfaces having a substantially right triangle shape will be referred to as a lower surface 222C.

As shown in FIG. 12, a screw insertion hole 222 </ b> D penetrating in the vertical direction is formed at the center in the length direction of the wedge member 222. In the state shown in FIG. 11, the screw insertion hole 222 </ b> D is a long hole that is long in the thickness direction of the balustrade panel 18 in a plan view.
In the longitudinal direction of the wedge member 222, female screws 222E and 222F penetrating in the vertical direction are formed on both sides of the screw insertion hole 222D.
Insertion holes 222G and 222H into which hexagon socket head bolts 230 to be described later are inserted are opened on both sides of both female screws 222E and 222F. Both insertion holes 222G and 222H are elongated holes similar to the screw insertion holes 222D.

The attachment member 208 portion provided with the wedge member 222 having the above-described configuration will be described with reference to FIG.
A female screw 208 </ b> A is formed in the mounting member 208 in the vertical direction corresponding to the screw insertion hole 222 </ b> D (FIGS. 11A and 12) of the wedge member 222.
In the length direction of the mounting member 208, on both sides of the female screw 208A, female screws 208B and 208C are formed in the vertical direction so as to correspond to the insertion holes 222G and 222H (FIGS. 11B and 12) of the wedge member 222. ing. As shown in FIGS. 13 (a) and 13 (c), a counterbore is made on the opening side above the female screws 208B and 208C.

  In the portion of the mounting member 208 where the wedge member 222 is provided, the second wall surface 214B is a flat surface, as represented by the cross-sectional view taken along the line VV, except where the internal threads 208A, 208B, 208C are formed. ing. The cross-sectional view taken along the line V-V is a cross-sectional view cut at a position corresponding to the female threads 222E and 222F (FIG. 12A) of the wedge member 222.

  Returning to FIG. 11, a manner of fixing the attachment member 208 to the upper end portion of the balustrade panel 18 will be described. As shown in FIG. 11A, a fastening screw 228 fitted with a flat washer 224 and a spring washer 226 is inserted into the screw insertion hole 222D of the wedge member 222 from below, and is screwed into the female screw 208A of the mounting member 208. Match. For the fastening screw 228, for example, a low-head hexagon socket head cap screw is used.

  FIGS. 11A and 11B show a state in which the attachment member 208 is fixed to the balustrade panel 18 by tightening the tightening screw 228. When the tightening screw 228 is tightened, the slope 222B of the wedge member 222 is skewed while being guided by the second wall surface 214B of the mounting member 208, and is pressed toward the second main surface 18B of the balustrade panel 18. As a result, the upper end portion of the balustrade panel 18 is clamped by the pressing surface 222A of the wedge member 222 and the first wall surface 214A of the attachment member 208, and the attachment member 208 is fixed to the balustrade panel 18. Become.

Each of the female threads 208B and 208C (FIGS. 13A, 13B, and 13C) of the mounting member 208 is screwed with a hexagon socket head bolt 230 (hereinafter simply referred to as “bolt 230”) as a bar member. The screw portion opposite to the head portion is inserted into the insertion holes 222G and 222H of the wedge member 222.
The bolts 230 provided in the mounting member 208 and the insertion holes 222G and 222H provided in the wedge member 222 are used when the wedge member 222 is tightened when the fastening screw 228 is tightened and when it is loosened as described later. It functions as a restricting means that restricts rotation around the heart.

When the tightening screw 228 is turned, the wedge member 222 into which the tightening screw 228 is screwed tries to rotate around the axis of the tightening screw 228 by the frictional force generated between the tightening screw 228 and the wedge member 222. In this case, if no care is taken, both ends of the wedge member 222 may collide with surrounding members, possibly damaging the member.
Therefore, the bolt 230 is brought into contact with the inner walls of the insertion holes 222G and 222H before rotating until it hits a surrounding member, and further rotation is restricted.
Note that the bar member used as the regulating means is not limited to the bolt 230, and for example, a pin may be used.

The fixing of the mounting member 208 to the balustrade panel 18 is released by loosening the fastening screw 228. When the tightening screw 228 is loosened, the tightening screw 228 is screwed downward. As a result, the pressing force with which the tightening screw 228 (the head thereof) presses the wedge member 222 against the second wall surface 214B is eliminated, and the wedge member 222 is pressed toward the second main surface 18B of the balustrade panel 18 as a result. The pressing force is canceled. Thereby, the wedge member 222 can be pulled down by hand.
When pulled down, as shown in FIG. 14A, the wedge member 222 falls until the lower surface 222 </ b> C contacts the flat washer 224. However, if the fastening screw 228 is removed from the female screw 208 </ b> A, the wedge member 222 is also removed from the mounting member 208.

By the way, depending on the manner in which the wedge member 222 bites into the protective member 216, even if the fastening screw 228 is loosened, the wedge member 222 may not be pulled down by hand alone. In this case, if the left and right side surfaces (both end surfaces in the direction perpendicular to the paper surface) of the wedge member 222 are struck with a metal rod or the like, the wedge member 222 is loosened by the impact, and the wedge member 222 cannot be dropped. However, it is not a reliable method.
In such a case, the loosening screw 232 is used in this embodiment. A method using the loosening screw 232 will be described with reference to FIG. FIG. 15 is a cross-sectional view including a transverse section of the wedge member 222 cut along a plane including the axis of the female thread 222E (FIG. 12) of the wedge member 222.

In the state where the tightening screw 228 (FIG. 11A) is loosened, the loosening screw 232 is screwed into the lower opening of the female screw 222E. For the loosening screw 232, for example, a relatively long hexagon socket head bolt as shown in the figure is used.
When the loosening screw 232 is screwed in, the loosening screw 232 is screwed upward, and its tip abuts against the second wall surface 214B of the mounting member 208. When the loosening screw 232 is screwed in even after the contact, the loosening screw 232 cannot be screwed any further, so that a force to make the wedge member 222 be screwed relatively downward acts. As a result, the wedge member 222 moves downward. When the wedge member 222 is loosened by this, when the tightening screw 228 is detached from the female screw 208A, the wedge member 222 is removed from the attachment member 208 in a state where the loosening screw 232 is screwed.
The loosening screw 232 is not always screwed to the wedge member 222 and is used only when removing the balustrade panel 18.

As described above, when the fixing of the attachment member 208 is released, the attachment member 208 is fitted to the upper end portion of the balustrade panel 18 with play in the thickness direction of the balustrade panel 18. In this case, as described above, if the lower end of the balustrade panel 18 is released and the front of the step 12 on the road RW side of the step 12 is opened, the balustrade panel 18 is removed. Can be removed.
The fixing device 204 having such a fixing structure will be described. As shown in FIG. 16, the fixing device 204 includes a fixed bracket 233 and a movable bracket 235.

The fixing bracket 233 includes a receiving member 234 and a plurality of (four in this example) restricting members 256, 258, 260, and 262, which will be described later. In this example, Z-shaped steel is used for the receiving member 234. A support plate 238 is joined to the receiving member 234 by welding (for example, fillet welding) (the weld bead is not shown).

  As shown in FIG. 10, an L-shaped angle member 240 is fixed to the truss 206 with bolts 242 and nuts 244. As shown in FIG. 16, the L-shaped angle member 240 is provided with a long hole 240 </ b> A, and the bolt 242 is inserted into the long hole 240 </ b> A and a through hole (not shown) formed in the truss 206, and the nut 244 is inserted. The L-shaped angle member 240 is fixed to the truss 206. In FIG. 16, the truss 206, bolt 242 and nut 244 are not shown.

Thus, the receiving member 234 (fixed bracket 233) is attached (fixed) to the truss 206 via the support plate 238 and the L-shaped angle member 240.

Returning to FIG. 16, a plurality (four in this example) of shaft support members 248, 250, 252, and 254 are joined to the receiving member 234 by welding (for example, fillet welding) (about the weld bead). Is not shown). As shown in FIG. 10, the shaft support member 248 is made of an L-shaped plate, and is joined to the receiving member 234 at the vertical plate portion 248 </ b> A. Further, as shown in FIG. 16, a shaft hole 248C is formed in the thickness direction at the tip of the horizontal plate portion 248B of the shaft support member 248.
The other three shaft support members 250, 252 and 254 are arranged at intervals in the longitudinal direction of the receiving member 234. Each of the shaft support members 250, 252, and 254 has substantially the same shape as the shaft support member 248, and is joined to the receiving member 234 in the same manner as the shaft support member 248. That is, the shaft support members 250, 252, and 254 are joined to the receiving member 234 at their vertical plate portions (the vertical plate portions of the shaft support members 250, 252, and 254 are not shown in the drawing), and the horizontal plate portion 250B. , 252B, 254B are provided with shaft holes 250C, 252C, 254C in the thickness direction. The four shaft holes 248C, 250C, 252C, and 254C are formed on the same axis.

Restricting members 256, 258, 260, and 262 are provided adjacent to the shaft supporting members 248, 250, 252, and 254, respectively. As shown in FIG. 17, the restricting member 256 has a shape in which the horizontal plate portion 248B (FIG. 10) is shortened in the shaft support member 248 (FIG. 10). Returning to FIG. 16, each of the restricting members 256, 258, 260, and 262 has its longitudinal plate portions 256 </ b> A, 258 </ b> A, 260 </ b> A, 262 </ b> A joined to the receiving member 234 in the same manner as the shaft support member 248.
Each of the front end surfaces of the horizontal plate portions 256B, 258B, 260B, and 262B of the restricting members 256, 258, 260, and 262 is a restricting surface 256C that restricts the rotation of each of the rotating arms 300, 302, 304, and 306 described later. , 258C, 260C, and 262C (FIG. 16B).

As shown in FIG. 18, block members 268 and 270 formed with female screws (not shown) are joined to both end portions in the length direction of the lower surface of the lower end portion 234 </ b> A of the receiving member 234. In the lower end 234A, through holes 234B and 234C corresponding to the female screw are formed. Height adjustment bolts 272 and 274 are screwed into the female screw from below, and their tips slightly protrude from the through holes 234B and 234C.
