Description

  The present invention relates to escalators and other passenger conveyors, and more particularly, to end covers for inner decks.

  On the escalator, on both sides of the traveling path of the steps for transporting passengers, balustrade panels are arranged along the traveling path, and an inner deck is provided between the lower part of the balustrade panel and the steps. I have.

  The step side end of the inner deck is connected to a skirt guard that stands upright with a slight gap from the step. On the other hand, the balustrade panel side end of the inner deck is fastened to a bracket fixed to the truss. Generally, a screw is used for the fastening member, and the screw is tightened from above in the state where the end of the inner deck is overlaid on the upper surface of the bracket end.

  If the head of the screw is visually recognized, it is not preferable in terms of design, so that the head of the screw and its vicinity are covered with a seal. Further, in order to improve the design, in Patent Literature 1, an elongated end cover made of a synthetic resin is provided to cover the side edge of the balustrade panel of the inner deck over its entire length.

  The end cover has a base portion having a laterally long U-shaped cross section, and a balustrade panel side edge of the inner deck is inserted into a groove of the base portion. In other words, the balustrade panel side edge is sandwiched between two band-like portions of the base portion. The base portion (the two band-shaped portions) has a through-hole that penetrates in the thickness direction of the inner deck, and the inner deck has a cutout corresponding to the through-hole.

  The inner deck in which the balustrade panel side edge is inserted into the base portion has the edge overlapped with the bracket in which the screw hole (female screw) is formed, and is inserted into the through hole and the notch. The set screw is screwed to the female screw. Thereby, the inner deck is fastened to the bracket by the screw.

  A flexible band-shaped cover portion extends from one end in the width direction of the base portion so as to cover the base portion. The screw head is hidden by the cover. From the passenger, only the band-shaped cover portion is visually recognized, and the screw head is hidden thereunder, so that the design is improved.

  By the way, the end cover provided on the balustrade panel side edge of the inner deck needs to be replaced due to aging deterioration or damage. In this case, in Patent Literature 1, in order to remove the end cover from the inner deck, first, the cover portion is turned to expose the screw head. Next, the screw is loosened using a screwdriver, and is pulled out from the notch and the through hole. That is, the fastening between the inner deck and the bracket is released. Then, by removing the base portion from the inner deck, the end cover is removed from the inner deck.

  However, it is necessary to release even the fastening of the inner deck and the bracket just to remove the end cover, which is very troublesome.

  The above-mentioned problem is not limited to the escalator, but is common to other passenger conveyors, for example, a moving sidewalk.

  The present invention has been made in view of the above problems, and has as its object to provide a passenger conveyor that can replace an end cover without necessarily releasing the fastening between a bracket and an inner deck.

  In order to achieve the above object, a passenger conveyor according to the present invention includes an endless transport body that circulates and transports passengers, and a balustrade panel that is erected along a passenger passage including a travel path of the endless transport body. A fixing device for fixing the balustrade panel to the truss at a lower end edge thereof, a bracket fixed to the fixing device and having an eave portion projecting in a direction intersecting with a main surface of the balustrade panel, and along the passage. An inner deck having an overlapped portion partially overlapped above the eaves portion in a plan view, and passing the overlapped portion and the eaves portion in the thickness direction thereof. A fastening member having been fastened, and an end cover attached to the inner deck, wherein the end cover is opposed to the first band-shaped portion and the first band-shaped portion, and is higher than the first band-shaped portion. A second band-shaped portion having a small width, the first band-shaped portion, A connecting portion for connecting the two band-shaped portions at one end side in the width direction, wherein the end cover is attached to an edge of the inner deck closer to the balustrade panel than the fastening member in the inner deck, and the first band-shaped The upper and lower portions of the second band-shaped portion are positioned downward, and the opposing regions of the two band-shaped portions are inserted and attached from one end in the longitudinal direction of the edge portion, and the two band-shaped portions in the opposing region are mounted. The distance between the facing portions is larger than the thickness of the edge portion, and the upper end portion of the fastening member is covered by a portion of the first belt portion that does not face the second belt portion.

  A gap is formed between the edge portion and the eave portion, and the end cover is mounted with the second band-shaped portion loosely inserted into the gap. And

  Further, when an external force is applied to the end cover and the end cover is slid toward the balustrade panel in the width direction of the first and second belt-shaped portions, the connecting portion contacts the passage-side main surface of the balustrade panel. Further, by restricting further sliding, the end cover is prevented from coming off from the inner deck in the width direction.

  Further, the end cover is formed of a synthetic resin to which a lubricant is added.

  In the passenger conveyor according to the present invention having the above configuration, the upper end portion of the fastening member that fastens the overlapping portion of the inner deck and the eaves portion of the bracket by penetrating them in the thickness direction is the end portion. The end cover is covered with a portion of the first band-shaped portion that is not opposed to the second band-shaped portion. It is inserted into and attached to the panel-side edge from one end in the longitudinal direction of the edge.

  In other words, the first band-shaped portion only covers the upper end portion of the fastening member, and the second band-shaped portion is closer to the balustrade panel side than the fastening member in the inner deck. Exist. In addition, the interval between the two band-shaped portions in the opposed region is larger than the thickness of the edge portion.

  Thus, the end cover can be removed (removed) from the one end of the edge by pulling out the lengthwise direction of the first and second strips. Further, the end cover can be attached by inserting a facing region of the first and second belt-shaped portions into the end portion from one end in a longitudinal direction of the end portion. That is, the end cover can be replaced without releasing the fastening of the fastening member for fastening the bracket (the eaves portion) and the inner deck (the overlapping portion).

Balustrades 14 and 16 are installed on both sides of a traveling path of the step 12 and a passenger passage PW including upper and lower elevators.

  Each of the balustrades 14 and 16 has a plurality of balustrade panels 18 erected along the passageway PW (in FIG. 1, the balustrade panels are denoted only by the balustrade panels constituting the balustrade 14 on one side). .). Each of the balustrade panels 18 is made of, for example, glass, and has a shatterproof film attached to one surface of a reinforced plate glass.

  On the outer periphery of the plurality of balustrade panels 18, there are provided endless belt-shaped moving handrails 20, 22 which are guided by guide rails (not shown in FIG. 1) and circulate at the same speed in the same direction as the steps 12. I have. The moving handrails 20 and 22 guided by the guide rails travel in the horizontal direction in a section (section where passengers grip) along the upper edge of the plurality of balustrade panels 18 and then curve and straightly incline. Go and curve again and run again in the horizontal direction.

  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 traveling direction of the steps 12 is switched, and the passenger riding on the steps 12 is moved 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.

  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 as a representative 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. Further, in FIG. 2, a fixing device 24 described later is shown without being cut, and hatching is omitted on a cut surface of other members for convenience.

  As shown in FIG. 2, the balustrade panel 18 has a lower end edge fixed to a truss (not shown) via a fixing device 24, and a guide rail 26 for guiding the moving handrail 20 is provided at the upper end edge. Fixed. The fixing device 24 includes an L-shaped angle member 28 attached to a truss (not shown) and a pressing plate 30 provided to face one surface of the L-shaped angle member 28. The L-shaped angle member 28 and the pressing plate 30 are made of a steel material. The number of the fixing devices 24 (two to four) according to the panel size is used per balustrade panel 18.

  At the lower end of the balustrade panel 18, a bracket 32 having a cross-sectional shape bent as shown in FIG. 2 is sandwiched via cushion sheets 34 and 36. The bracket 32 is, for example, a sheet metal processed material of a steel plate (for example, a stainless steel plate), and the cushion sheets 34 and 36 are formed of rubber or soft synthetic resin. In addition, a spacer 38 is provided between the bracket 32 and the pressing plate 30, as shown in FIG. The spacer 38 is formed of a steel material. The bracket 32 is provided for each fixing device 24.

  Through holes (not shown) are respectively formed at positions corresponding to the L-shaped angle member 28 and the pressing plate 30, and bolts 40 are inserted into both the through holes. A nut 42 is screwed into the bolt 40, the bolt 40 and the nut 42 are tightened, and the lower end edge of the balustrade panel 18 is formed by the L-shaped angle member 28 and the pressing plate 30, the bracket 32, and the cushion sheet. 34, 36 and a spacer 38, and are fixed to a truss (not shown).

  The upper end of the bracket 32 fixed as described above to the fixing device 24 for fixing the balustrade panel 18 to a truss (not shown) at its lower end edge protrudes in a direction intersecting with the main surface 18A of the balustrade panel 18. In this example, it is formed on the eave portion 32A (extending from the balustrade panel 18 side to the passage PW side).

  A part of the inner deck 44 is overlaid on the eave portion 32A of the bracket 32 in plan view. The inner deck 44 is basically formed by bending (sheet metal processing) a long stainless steel plate so that its cross section becomes an "H" shape as shown in FIG. Here, in the inner deck 44, a portion inclined with respect to the horizontal direction is referred to as an inclined portion 44A, and a portion parallel to the vertical direction is referred to as a side plate portion 44B. The total length of the inner deck 44 is, for example, 3600 mm. The overlapping portion 44C (FIG. 2) that overlaps the eaves portion 32A in the inclined portion 44A of the inner deck 44 is subjected to burring at a predetermined interval (for example, 600 mm) in the longitudinal direction, whereby the burring process is performed downward. A plurality of protruding cylindrical portions 44D are formed at the predetermined intervals.

  As shown in FIG. 4, a female screw 32B is formed in the eaves portion 32A of the bracket 32 in the thickness direction corresponding to the cylindrical portion 44D of the inner deck 44.

  A countersunk screw 46, which is a fastening member inserted into the cylindrical portion 44D from above, is screwed into the female screw 32B, and the overlapping portion 44C and the eaves portion 32A are fastened by the countersunk screw 46.

  A gap CL is formed between the overlapping portion 44C and the eaves portion 32A with the cylindrical portion 44D interposed therebetween in a state where the screw is fastened by the flathead screw 46.

  An end cover 48 is attached to the inner deck 44. The details of the end cover 48 will be described later.

  A plurality of inner decks 44 fastened to the bracket 32 as described above are arranged side by side with their end faces in the longitudinal direction facing each other in the section where the moving handrail 20 is skewed.

  In the section where the moving handrail 20 is curved, a section in which the middle portion of the inner deck 44 in the longitudinal direction is curved in accordance with the curve (hereinafter, referred to as “curved inner deck”) is used. The curved inner deck is installed (arranged) with one end face abutting on the end face of the inner deck 44 installed at one end of the skewed section. Here, of the plurality of inner decks 44 arranged in a row, the curved inner deck adjacent to the lower inner deck 44 is referred to as a “lower curved inner deck”, and the curved inner deck adjacent to the upper inner deck 44 is referred to as “upper inner deck”. It will be referred to as "curved inner deck".

  Also, of all the inner decks arranged in a row, the inner decks installed at both ends (the inner decks adjacent to the lower curved inner deck or the upper curved inner deck) are referred to as “end inner decks”, and , The one provided at the elevator at the lower floor DS side is referred to as a "lower deck inside", and the one provided at the elevator US at the floor US upper floor is referred to as "upper deck". .

  As shown in FIG. 5, the end of the lower end inner deck 50 opposite to the lower curved inner deck is subjected to sheet metal processing.

  The lower end inner deck 50 has basically the same shape as the inner deck 44 except that the shape of one end portion in the longitudinal direction is different. Therefore, in the lower end inner deck 50, the same name as the inner deck 44 is used for the substantially same portion as the inner deck 44.

  The one end portion of the lower end inner deck 50 is formed by punching a one end portion of a long stainless steel plate into a predetermined shape and then bending it as shown in FIG. Note that the upper end inner deck (not shown) has basically the same configuration as the lower end inner deck 50, and a description thereof will be omitted.

  One end portion of the lower end inner deck 50 in the longitudinal direction is bent downward except for the edge portion 50E. A U-shaped notch 50G is formed in the bent portion 50F that is bent downward at one end in the longitudinal direction. A bent portion 50H is formed between the bent portion 50F and the side plate portion 50B, and is bent downward with a fold that is inclined with respect to the edge portion 50E.

  A block member 52 having a female screw 52A formed so as to be seen through the notch 50G is joined to the inside of the bent portion 50F of the lower end inner deck 50 by fillet welding or the like.

  The lower end inner deck 50, the lower curved inner deck, the plurality of inner decks 44, the upper curved inner deck, and the upper end inner deck configured as described above are arranged in this order along the passage PW. ing. In the arranged state, the inclined portions including the edge portions of the adjacent inner decks and the side plate portions are flush with each other at least at the abutting portions.

  Returning to FIG. 2, a skirt guard 54 is erected on the inner side of the side plate portion 44 </ b> B of the inner deck 44 so as to overlap the upper edge. In the skirt guard 54, a reinforcing plate 56 is joined to the upper end of the main surface opposite to the passage PW. An upper clip 58 is joined to the reinforcing plate 56. A lower clip 60 is joined to a lower end of the main surface of the skirt guard 54.

  Inside the skirt guard 54 (the side not facing the passage PW), an upper support portion 62 made of an L-shaped angle material and a lower support portion 64 made of an equilateral angle steel are provided vertically. The upper support 62 and the lower support 64 are fixed to a truss (not shown).

  As shown in FIG. 2, a part of the upper support part 62 is sandwiched between the upper clip 58 and a part of the skirt guard 54, and a part of the lower support part 64 is held by the lower clip 60 and a part of the skirt guard 54. The skirt guard 54 is supported by the upper support portion 62 and the lower support portion 64, with the lower end surface 56 </ b> A of the reinforcing plate 56 abutting against the upper end surface 62 </ b> A of the upper support portion 62.

  Since only a part of the skirt guard 54 is overlapped on the side plate portion 44B of the inner deck 44 and is not fastened with screws or the like, a cover is not necessarily provided at the end on the side plate portion 44B side. There is no need to provide.

  On the other hand, since the head of the countersunk screw 46 is exposed from the overlapping portion 44C which is the other end of the inner deck 44 (FIG. 4), an end cover 48 for covering the same is provided. Have been.

  As shown in FIG. 6, the end cover 48 has a generally elongated band shape and is made of an extruded synthetic resin. As the synthetic resin, for example, 6 nylon containing molybdenum disulfide is used. The end cover 48 has a total length of 2 to 3 m and has flexibility.

  The end cover 48 includes a first band-shaped portion 481, a second band-shaped portion 482 facing the first band-shaped portion 481, and having a smaller width than the first band-shaped portion 481, and a first band-shaped portion 481 and a second band-shaped portion 482. And a connecting portion 483 that connects at one end side in the width direction.

  Here, in the width direction of the first belt-shaped portion 481, a portion facing the second belt-shaped portion 482 is referred to as a facing portion 481A, and a portion not facing the second belt-shaped portion 482 is referred to as a non-facing portion 481B. The space Dc between the facing portion 481A and the second band-shaped portion 482 is referred to as “facing space Dc”, and the space between the facing portion 481A and the second band-shaped portion 482 is referred to as “facing region Fr”. I do.

  The non-opposing portion 481B of the first band portion 481 is bent so as to be closer to an end in the width direction of a virtual plane including a surface 482A of the second band portion 482 facing the first band portion 481.

  The facing distance Dc is set to be larger than the thickness Td (hereinafter, referred to as “edge thickness Td”) at the edges 44E, 50E of the inner decks 44, 50 shown in FIG. (Dc> Td).

  Further, the thickness Tc of the second band-shaped portion 482 (hereinafter, referred to as “second band-shaped portion thickness Tc”) is equal to the edge portions 44E, (50E) of the inner decks 44, (50) and the bracket shown in FIG. The gap Dd is set to be smaller than the gap Dd (hereinafter, referred to as “gap gap Dd”) between the 32 and the eaves 32A (Tc <Dd).

  As shown in FIG. 4, the end cover 48 having the above-described configuration is configured such that the first band-shaped portion 481 is on the upper side and the second band-shaped portion 482 is on the lower side, and It is mounted in a state where the edge portion 44E closer to the balustrade panel 18 than 46 is fitted.

  In the mounted state, the non-opposing portion 481B of the first band-shaped portion 481 covers the head 46A, which is the upper end portion of the flat head screw 46. Thereby, the head 46A of the countersunk screw 46 is not visually recognized by the passenger, so that the design of the escalator is not impaired. Further, since the member for hiding the head 46A of the flat head screw 46 is a band-shaped end cover 48 attached to the edge portions 44E, 50E of the inner decks 44, 50, the design of the escalator is improved. .

  The inner deck includes a lower end inner deck 50, a lower curved inner deck, a plurality of inner decks 44, an upper curved inner deck, and an upper inner deck from the elevator entrance side of the lower floor DS to the elevator entrance side of the upper floor US. Are arranged in this order, and a plurality of end covers 48 are attached over the entire length of the edge portion of the arranged inner deck. The plurality of end covers 48 are arranged in a row in such a manner that end faces in the longitudinal direction of the adjacent end covers 48 abut against each other.

  4 and 6B, no care is taken because the dimensions Dc, Td, Tc, and Dd are in the relationship of Dc> Td and Tc <Dd as described above. Then, the end cover 48 may be detached from the lower end inner deck 50 in its length direction. Even if it does not come off, one end of the end cover 48 may hang down from the lower end inner deck 50.

  Therefore, a stopper cap 66 of the end cover 48 is provided on the lower inner deck 50 as shown in FIG. The retaining cap 66 has a screw insertion hole (not shown in the figure), is inserted into the screw insertion hole, and a screw 68 screwed into the female screw 52A (FIG. 5) of the block member 52 is tightened. A retaining cap 66 is attached to the lower end inner deck 50. This prevents the end cover 48 from coming off in the length direction. A stopper cap similar to the stopper cap 66 is also attached to the upper inner deck (not shown).

  Also, the inner cover (lower end inner deck 50, lower curved inner deck, plural inner decks 44, upper curved inner deck, and upper end inner deck) prevents the end cover 48 from coming off in the width direction as follows. It is planned.

  The prevention of the end cover 48 from coming off in the width direction will be described with reference to FIG. When some external force is applied to the end cover 48 and the end cover 48 is slid toward the width direction (the width direction of the first band-shaped portion 481 and the second band-shaped portion 482) toward the balustrade panel 18, the end cover 48 is slid. The connecting portion 483 of 48 abuts the main surface 18A of the balustrade panel 18 on the side of the passage PW (FIG. 1), and further sliding is restricted. This prevents the end cover 48 from coming off the inner deck 44 in the width direction. That is, (the main surface 18A of) the balustrade panel 18 functions as a stopper for preventing the end cover 48 from coming off.

  When the balustrade panel 18 functions as a stopper, that is, when the connecting portion 483 comes into contact with the main surface 18A of the balustrade panel 18, the inner deck 44 is located in the facing region Fr between the first belt-like portion 481 and the second belt-like portion 482. The width of the second band-shaped portion 482 and the end of the inner deck 44 are connected to the connecting portion 483 so that a part of the edge 44E of the inner belt 44 fits and the edge 44E does not completely come out of the facing region Fr. The distance and the like between the connecting portion 483 and the main surface 18A when the tip of the edge 44E is in contact (when the edge 44E is fitted to the entire opposing area Fr) are set.

  Next, a method of replacing the end cover 48 in the escalator 10 configured as described above will be described.

Loosen the screw 68 and remove the retaining cap 66 (FIG. 7) from the lower end inner deck 50.
The end portion of the end cover 48 attached to the lower end inner deck 50 on the bent portion 50F side is pulled in the length direction. Then, since the relationship of (opposite interval Dc)> (edge portion thickness Td), (second band portion thickness Tc) <(gap interval Dd), the end cover 48 can be pulled out in the length direction. Further, since the end cover 48 is formed of a synthetic resin (in this example, 6 nylon) to which a lubricant (in this example, molybdenum disulfide) is added, slidability with respect to the edge of the inner deck is provided. Is also improved, which also makes it easy to pull out in the length direction.

  In addition, the first belt-shaped portion 481 (the non-opposing portion 481B) only covers the head portion 46A of the flathead screw 46, and the second belt-shaped portion 482 is larger than the countersunk screw 46 in the inner deck 44 than the balustrade panel 18. Due to the presence of the side edge portion 44E, the end cover 48 merely passes through the plurality of flathead screws 46 during extraction, and the flathead screws 46 do not hinder the extraction. Thereby, the fastening by the flathead screw 46 between each inner deck (the lower inner deck 50, the lower curved inner deck, the plurality of inner decks 44, the upper curved inner deck, and the upper inner deck) with the corresponding bracket 32 is released. Instead, the end cover 48 can be detached (removed) from the inner deck.

  As described above, the lower half of the plurality of end covers 48 is removed from the lower end inner deck 50. The upper half is extracted from the upper inner deck (not shown) in the same manner as described above.

  The attachment (attachment) of the end cover 48 to the inner deck (the lower inner deck 50, the lower curved inner deck, the plurality of inner decks 44, the upper curved inner deck, and the upper inner deck) is the reverse of the above-described removal. Done in steps. That is, one end of the end cover 48 is inserted through one end of the edge 50E of the lower end inner deck 50, and the one end 48A (tip) of the first band-shaped portion 481 shown in FIG. By pulling along (ie, in the direction of arrow A), the end cover 48 is attached through the entire edge of the inner deck.

  Half of the plurality of end covers 48 is inserted through the lower end inner deck 50 for mounting, and when the mounting is completed, the retaining cap 66 is attached to the lower end inner deck 50 with screws 68 (FIG. 7). The other half is inserted by being inserted from the upper end inner deck (not shown), and when the mounting is completed, a retaining cap is attached to the upper end inner deck with a screw (both not shown). At the time of insertion, the end cover 48 merely passes through the plurality of flathead screws 46, and the flathead screws 46 do not hinder the insertion, so that each inner deck (lower end inner deck 50, lower curved inner deck, The end cover 48 can be mounted (attached) to the inner deck without releasing the fastening of the corresponding inner brackets 32, the upper curved inner deck, and the upper end inner deck) and the corresponding brackets 32 with the countersunk screws 46. .

  Thus, the replacement of the end cover 48 is completed. In addition, not only at the time of replacement but also at the time of attaching the end cover 48 to the inner deck for the first time when the escalator 10 is newly installed, the end cover 48 is attached at the installation site in the same manner as described above.

  In the first embodiment, as described with reference to FIG. 4, the cylindrical portion 44 </ b> D formed by burring the overlapping portion 44 </ b> C of the inner deck 44 causes the edge portion 44 </ b> E of the inner deck 44 and the eave portion 32 </ b> A of the bracket 32. A gap CL in which the second band-shaped portion 482 of the end cover 48 is loosely inserted is created, but the gap CL is not limited to this and is created as in Modifications 1 and 2 shown in FIG. It does not matter. In FIG. 9, the same reference numerals as in the first embodiment denote the same components as those in the first embodiment.

(Modification 1)
In the first modification, as shown in FIG. 9A, the gap CL is created by bending the end of the inner deck 70 on the side of the balustrade panel 18.

  Further, the overlapping portion 70C of the bracket 32 and the eave portion 32A of the bracket 32 in the inner deck 70 and the eave portion 32A are fastened with pan head screws 72 which are fastening members.

  The end cover 74 is slightly different in shape from the end cover 48 (FIG. 4 and the like), but has the same basic configuration. That is, the end cover 74 includes a first band-shaped portion 741, a second band-shaped portion 742 opposed to the first band-shaped portion 741 and narrower than the first band-shaped portion 741, a first band-shaped portion 741 and a second band-shaped portion. 742 and a connecting portion 743 for connecting at one end side in the width direction.

  In the end cover 74, the edge portion 70E of the inner deck 70 fits in the facing region Fr between the facing portion 741A facing the second belt portion 742 and the second belt portion 742 in the first belt portion 741.
