Description

  Embodiments of the present invention relate to a passenger conveyor.

  As shown in FIGS. 1 and 2, the passenger conveyor 1 normally includes a plurality of steps 3 connected in an endless manner that circulates, and a boarding / exiting plate that serves as an opening / closing plate for a machine room at the boarding / exiting step 3. 2 is arranged. The boarding / alighting plate 2 is usually composed of a rectangular plate divided into a plurality of parts, and as shown in FIG. 3, the boarding / exiting plate 2 is placed on the support frames 4 provided at both the left and right sides from the step side. Installed in parallel toward the side and bolted. The support frame 4 is composed of a vertical panel 4a serving as a partition from the building and an L-shaped panel 4b attached to the vertical panel 4a. The surface of the top plate 2a constituting the boarding / alighting plate 2 is provided with an etching pattern that has both slipperiness and design for passengers.

  Further, as shown in FIGS. 22 and 24, the conventional boarding board 102 is provided with step prevention metal fittings 2b at both ends on the step side and the landing side so as not to cause a level difference between adjacent boarding boards. ing. As shown in FIG. 21, the level difference prevention metal fitting 2b is attached at two places on the boarding board step side and at one place on the boarding board landing side.

  The top plate 2a of the boarding / alighting plate 2 is usually manufactured by pressing a steel plate having a thickness of about 1 to 2 mm, and the top plate 2a alone cannot support a load when a user passes. Therefore, conventionally, a U-shaped reinforcing member 105 having a U-shaped cross-section shown in FIG. 23 is welded to the lower surface of the boarding board to increase the strength as shown in FIGS. As shown in FIG. 24, the reinforcing member 105 supports the boarding / alighting plate 2 by placing the bottom surface on the bottom surface of the L-shaped panel 4b having the L-shape. As shown in FIGS. 22 and 27, the reinforcing member 105 is installed except for 10 to 20 mm from the end edge 102a 'of the top plate 102a.

  When the passenger conveyor is maintained and inspected, the board 102 is opened and closed. At that time, as shown in FIGS. 25 and 26, the landing side is lifted with the step side of the board 102 as a fulcrum. Become. For example, during the inclination angle α from the state shown in FIG. 27 to the state shown in FIG. 28, the conventional boarding board 102 has a contact point between the lower end 105 ′ of the reinforcing member 105 and the bottom surface 4 b ′ of the L-shaped panel 4 b as a fulcrum. Since the boarding side of the boarding board 102 is lifted, the top board edge 102a ′ is not affected. However, when the boarding / alighting plate 102 is lifted beyond the inclination angle α, the reinforcing material 105 does not reach the edge 102a ′ of the top board 102a, so that the top board edge 102a ′ on the boarding / alighting board step side and L Contact with the top 4b '' of the character panel 4b cannot be avoided. As a result, as shown in FIG. 29, the lower end 105 ′ of the reinforcing member 105 is lifted, and the contact point between the top 4b ″ of the L-shaped panel 4b and the top edge 102a ′ is used as a fulcrum in FIG. The boarding board will be lifted in the contact state shown. Therefore, the total weight of the boarding / alighting plate 102 is applied to the top plate edge 102a 'on the boarding / alighting board step side.

  The problem to be solved by the present invention is that when the board is opened and closed, the edge of the both sides of the board is not in contact with the lower support frame, so that the board is lifted on the landing side. It is sometimes to provide a passenger conveyor in which the step edge of the boarding board is not a fulcrum.

  The passenger conveyor according to the embodiment of the present invention extends the lower support of the U-shaped reinforcing member in cross section and lifts the boarding side of the boarding board to open and close the boarding board when the boarding board is opened and closed. That is, the side edge is not in contact with the lower support frame.

  Hereinafter, a passenger conveyor according to an embodiment of the present invention will be described with reference to the drawings. The schematic configuration of the passenger conveyor is as described in the section of the background art, and since the embodiment of the present invention is an improvement of the reinforcing material, the reinforcing material will be described in detail. The configuration described in the section is used.

  4 to 8 show a first embodiment.

  4 to 8, reference numeral 15 denotes a reinforcing material. As shown in FIG. 6, the reinforcing material 15 is a steel material having a U-shaped cross section including an upper support 15a, an intermediate support 15b, and a lower support 15c. Composed. As shown in FIG. 4, the upper support 15a is attached to the lower surface side of the top plate 12a of the board 12 and the lower support 15c is a bottom surface 4b 'of the L-shaped panel 4b of the support frame 4 shown in FIG. The board 12 is supported by the support frame 4. Specifically, the boarding / alighting plate 12 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 15 attached to the lower surface side of the top plate 12a. Further, the end portion 15c ′ of the lower support 15c is longer than the upper support 15a and has a length extending to the step edge 12a ′ of the top plate 12a of the boarding plate 12 so that the boarding plate 12 can be opened and closed. It plays the role which prevents the contact with edge 12a 'of the top plate 12a and the support frame 4 which generate | occur | produces at the time of work.

  When opening and closing the board 12, the platform side of the board 12 is lifted with the step side of the board 12 as a fulcrum. At this time, as shown in FIG. 5, the end 15c 'of the lower support 15c serves as a fulcrum, and the end of the board 12 and the support frame 4 do not contact each other. That is, since the lower support 15c is formed to have a length that extends to the step edge 12a 'of the top plate 12a of the board 12 as shown in FIG. 8, the board 12 shown in FIG. In the process of tilting the boarding side of the boarding board to the lifted state, the end portion 15c ′ of the lower support 15c of the reinforcing member 15 contacts the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and this contact point The board 12 is lifted up as a fulcrum, and the edge 12a ′ of the top 12a contacts the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ1 shown in FIG. Become. This inclination angle θ1 is formed by extending the lower support 15c to the step edge 12a ′ of the top plate 12a of the board 12 so that the inclination angle α in the conventional board 102 shown in FIG. The angle is large enough to lift the landing side of the board 12 to remove the board 12. Therefore, the lower support 15c is formed to have a length that extends to the step edge 12a ′ of the top plate 12a of the board 12 so that the edge 12a ′ of the top plate 12a can be connected to the L-shaped panel 4b of the support frame 4. The board 12 can be removed before it comes into contact with the top 4b ''.

  Thus, the boarding board 12 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 12 is the end 15c ′ of the lower support 15c of the reinforcing member 15, and the edge 12a ′ of the top board 12a serves as the fulcrum. It is not necessary to incline the boarding board 12 to a certain point. Therefore, the contact between the edge 12a ′ of the top plate 12a and the support frame 4 is eliminated, and therefore, the edge 12a ′ of the board 12 is not damaged by cracks or bends. There is no possibility that the design of the surface of the plate top plate is impaired.

  9 to 11 show a second embodiment.

  In the second embodiment, the length of the lower support 15 c in the first embodiment is extended longer than the end of the vertical projection surface of the boarding / alighting plate 12. That is, the reinforcing member 25 shown in FIG. 9 is formed of a steel material having a U-shaped cross section including an upper support 25a, an intermediate support portion 25b, and a lower support 25c. As shown in FIG. 10, the upper support 25 a is attached to the lower surface side of the top plate 22 a of the boarding plate 22, and the lower support 25 c is placed on the bottom surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The boarding / alighting plate 22 is supported by the support frame 4. Specifically, the boarding / alighting plate 22 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 25 attached to the lower surface side of the top plate 22a.

  When opening and closing the boarding board 22, the landing side of the boarding board 22 is lifted with the step side of the boarding board 22 as a fulcrum. At this time, the end 25c 'of the lower support 25c serves as a fulcrum, and the end of the board 22 and the support frame 4 do not contact each other. That is, since the lower support 25c is formed longer than the end of the vertical projection surface of the boarding / alighting plate 22, the boarding side of the boarding / alighting plate shown in FIG. 11 is lifted from the state where the boarding / alighting plate 22 shown in FIG. In the process of inclining to the raised state, the end portion 25c ′ of the lower support 25c of the reinforcing member 25 comes into contact with the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and the boarding plate 22 is lifted as a fulcrum. Then, the edge 22a ′ of the top plate 22a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ2 shown in FIG. This inclination angle θ2 is larger than the inclination angle α in the conventional boarding board 102 shown in FIG. 28 by forming the lower support 25c longer than the end of the vertical projection surface of the boarding board 22 and the first embodiment. In this embodiment, the angle is steeper than the inclination angle θ1 and is sufficient to lift the boarding side of the boarding board 22 to remove the boarding board 22. Therefore, the lower support 25c is formed longer than the end of the vertical projection surface of the boarding / alighting plate 22, so that the edge 22a 'of the top plate 22a contacts the top 4b' 'of the L-shaped panel 4b of the support frame 4. It becomes possible to remove the boarding board 22 by the time.

  Thus, the boarding board 22 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 22 is the end 25c ′ of the lower support 25c of the reinforcing member 25, and the edge 22a ′ of the top board 22a serves as the fulcrum. It is not necessary to incline the boarding board 22 to a certain point. Therefore, there is no contact between the edge 22a 'of the top plate 22a and the support frame 4, and therefore no distortion due to cracks or bending occurs at the edge 22a' of the boarding plate, so that the boarding plate 22 is damaged, There is no possibility that the design of the surface of the boarding board is impaired.

  In addition, as the end of the lower support is made shorter than the vertical projection plane of the board, the inclination angle of the board becomes gentler, so the edge of the board top plate and the support frame may come into contact with each other However, in the present embodiment, the end portion 25c ′ of the lower support 25c is made longer than the vertical projection surface of the boarding plate 22, so that the end edge 22a ′ of the top plate 22a, the support frame 4 and There will be no further contact. Therefore, since the contact between the boarding / alighting plate 22 and the support frame 4 can be more reliably eliminated, distortion due to a crack or a bend does not occur more reliably at the edge 22a 'of the boarding / alighting plate top plate.

  12 to 15 show a third embodiment.

  In the third embodiment, the end portion 15c 'of the lower support 15c in the first embodiment is bent. That is, the reinforcing member 35 shown in FIG. 12 is made of a U-shaped steel material having an upper support 35a, an intermediate support part 35b, and a lower support 35c. As shown in FIG. 13, the upper support 35 a is attached to the lower surface side of the top plate 32 a of the passenger board 32, and the lower support 35 c is placed on the bottom surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The boarding / alighting plate 32 is supported by the support frame 4. Specifically, the boarding / alighting plate 32 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 35 attached to the lower surface side of the top plate 32a.

  When opening and closing the boarding board 32, the platform side of the boarding board 32 is lifted with the step side of the boarding board 32 as a fulcrum. At this time, the end portion 35c 'of the lower support 35c serves as a fulcrum, and the end portion of the boarding / exiting plate 32 and the support frame 4 do not contact each other. That is, since the lower support 35c is formed to have a length that extends to the step edge 32a 'of the top plate 32a of the board 32, the board 32 shown in FIG. 13 is not lifted, as shown in FIG. In the process of tilting the boarding side of the boarding board to the lifted state, the end portion 35c ′ of the lower support 35c of the reinforcing member 35 comes into contact with the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and this contact point The board 32 is lifted up as a fulcrum, and the edge 32a ′ of the top plate 32a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ3 shown in FIG. Become. This inclination angle θ3 is formed by extending the lower support 35c to the step edge 32a ′ of the top plate 32a of the board 32, so that the inclination angle α in the conventional board 102 shown in FIG. The angle is large enough to lift the landing side of the boarding board 32 in order to remove the boarding board 32. Therefore, the lower support 35c is formed to have a length that extends to the step edge 32a 'of the top plate 32a of the board 32, so that the edge 32a' of the top plate 32a is formed on the L-shaped panel 4b of the support frame 4. It is possible to remove the boarding / alighting plate 32 before it comes into contact with the top 4b ″.

  Thus, the boarding / alighting plate 32 can be removed in a state where the fulcrum during the opening / closing operation of the boarding / alighting plate 32 is the end 35c ′ of the lower support 35c of the reinforcing member 35, and the edge 32a ′ of the top plate 32a serves as a fulcrum. There is no need to incline the board 32. Accordingly, there is no contact between the edge 32a 'of the top plate 32a and the support frame 4, so that the edge 32a' of the boarding / alighting plate does not undergo distortion due to cracks or bends. There is no possibility that the design of the surface of the plate top plate is impaired.

  Further, since the end portion 35c ′ of the lower support 35c of the reinforcing member 35 is bent into a curved shape by bending, when the boarding plate 32 is opened and closed, the platform side of the boarding plate 32 is lifted and the step side or platform is tilted. There is an advantage that the work of sliding to the side is easier than when bending is not performed.

  15 to 17 show a fourth embodiment.

  In the fourth embodiment, a sliding portion is attached, for example, with an adhesive or the like, to an end portion 35c 'where the lower support 35c is bent in the third embodiment. That is, the reinforcing material 45 shown in FIG. 15 uses all the configurations described in the third embodiment, and the same reference numerals are given.

  In the fourth embodiment, as shown in FIGS. 15 to 17, the lower surface side of the curved end portion 35 c ′ of the lower support 35 c of the reinforcing member 45, that is, the lower surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The sliding part 45d is provided in the place which contacts with. A low friction and low wear material excellent in self-lubricity is bonded to the sliding portion 45d by an adhesive method such as using an adhesive. As the material, a metal-based or ceramic-based material may be used, and a resin-based material may be used because it does not become hot.

  Thus, in the present embodiment, since the sliding portion 45d is attached to the lower surface of the end portion 35c ′ of the lower support 35c that contacts the support frame 4 in the reinforcing member 45, the end portion 35c ′ of the lower support 35c and Friction with the support frame 4 can be reduced. Therefore, the movement on the support frame 4 of the boarding board 42 becomes easy. Therefore, in addition to the operational effects of the third embodiment, there is an advantage that the sliding work performed during the opening / closing work of the boarding / alighting plate 42 can be performed more easily.

  18 to 20 show a fifth embodiment.

  In the fifth embodiment, a roller 55f is attached to the end portion 15c 'of the lower support 15c in the first embodiment. That is, the reinforcing member 55 shown in FIG. 18 is formed of a steel material having a U-shaped cross section including an upper support 55a, an intermediate support part 55b, and a lower support 55c. As shown in FIG. 19, the upper support 55a is attached to the lower surface side of the top plate 52a of the passenger board 52, and the lower support 55c is placed on the bottom surface 4b 'of the L-shaped panel 4b of the support frame 4. The boarding / alighting plate 52 is supported by the support frame 4. Specifically, the boarding / alighting plate 52 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing material 55 attached to the lower surface side of the top plate 52a. The roller 55f attached to the end 55c ′ of the lower support 55c has a rotation axis that is orthogonal to the step direction, and can roll on the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4. It is configured. The roller 55f is not limited to the one in this embodiment, and may have any configuration as long as it can roll in the step direction.

  When opening and closing the boarding board 52, the landing side of the boarding board 52 is lifted with the step side of the boarding board 52 as a fulcrum. At this time, the lower surface of the roller 55f attached to the end portion 55c 'of the lower support 55c serves as a fulcrum, and the end portion of the passenger board 52 and the support frame 4 do not contact each other. That is, by forming the lower support 55c, in the process of inclining from the state where the boarding board 52 shown in FIG. 19 is not lifted to the state where the boarding side of the boarding board shown in FIG. The roller 55f attached to the end portion 55c 'of the lower support 55c of the lower portion of the lower support 55c comes into contact with the bottom surface 4b' of the L-shaped panel 4b of the support frame 4, and the board 52 is lifted with this contact point as a fulcrum. The edge 52a ′ of the top plate 52a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ5 shown. This inclination angle θ5 is formed by extending the lower support 55c to the step edge 52a ′ of the top plate 52a of the board 52, so that the inclination angle α in the conventional board 102 shown in FIG. Although it is large and becomes slightly gentler than the inclination angle θ1 in the first embodiment by attaching the roller 55f, it is a sufficient angle to lift the landing side of the boarding board 52 in order to remove the boarding board 52. Therefore, the lower support 55c is formed to have a length that extends to the step edge 52a 'of the top plate 52a of the board 52, so that the end edge 52a' of the top plate 52a is formed on the L-shaped panel 4b of the support frame 4. It is possible to remove the boarding / alighting plate 52 before it comes into contact with the top 4b ″.

  Thus, the boarding board 52 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 52 is the roller 55f attached to the end 55c 'of the lower support 55c of the reinforcing member 55, and the edge of the top board 52a It is not necessary to incline the boarding / alighting plate 52 to the point where 52a ′ becomes a fulcrum. Therefore, the contact between the end edge 52a ′ of the top plate 52a and the support frame 4 is eliminated, and therefore, the end edge 52a ′ of the boarding / alighting plate does not generate distortion due to cracks or bending. There is no possibility that the design of the surface of the boarding board is impaired.

  Further, since the roller 55f that can roll on the support frame 4 is attached to the end 55c ′ of the lower support 55c of the reinforcing member 55, the landing side of the board 52 is lifted when the board 52 is opened and closed. There is an advantage that the work of sliding to the step side or the landing side in an inclined state is easier than when the roller 55f is not attached. Moreover, there is an advantage that contact between the support frame 4 and the lower support 55c can be suppressed at the same time.

  In addition, although the present Example demonstrated the escalator, it is applicable also to a moving sidewalk. Further, the embodiment is an exemplification, and the scope of the invention is not limited to the embodiment.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
