It is driven to move along.

  The handrail deck 36 corresponds to the top of the balustrade part, and is a member having the function of holding the handrail part 32 by attaching the handrail deck 36 described above. As the handrail deck 36, a material obtained by bending an appropriate metal plate can be used.

  The handrail-side angle member 38 attached to the lower portion of the handrail deck 36 is a bent plate material formed by bending an appropriate metal plate. The handrail side angle member 38 has a function as a fixing portion for fixing the inner panel 50 with the mounting screw 40 and a rotation shaft 62 for supporting the inner panel 50 on the conveyor 12 side so as to be opened and closed. It has a function as a mounting portion for attaching the shaft base portion 60.

  In the handrail side angle member 38, the overhanging portion 39 that protrudes to the lower side, that is, the skirt guard 26 side, is a portion that functions as a fixing portion for fixing the inner panel 50 with the mounting screw 40. The projecting portion 39 is provided with a screw hole corresponding to the mounting hole of the inner panel 50. Therefore, the inner panel 50 is firmly fixed to the handrail side angle member 38 by positioning with respect to the mounting hole of the inner panel 50 and the screw hole of the overhanging portion 39 and screwing the mounting screw 40 into the screw hole through the mounting hole. . When the mounting screw 40 is removed, the inner panel 50 becomes free with respect to the handrail side angle member 38.

  The rotation shaft base 60 attached to the handrail side angle member 38 is a block member having a rotation shaft 62 that is a tip shaft that protrudes below the handrail side angle member 38, that is, toward the skirt guard 26. The rotating shaft base 60 is fixed to the handrail side angle member 38 by appropriate fixing means such as screwing or welding. The rotating shaft 62 is a protruding shaft configured integrally with the rotating shaft base 60.

  The skirt guard 26 disposed parallel to the side surface of the tread plate 14 corresponds to the base portion of the balustrade portion 30, and here is an angle member formed by bending an appropriate metal plate. The skirt guard 26 has a function similar to that of the handrail side angle member 38 in addition to the function of being disposed on the side surface of the tread plate 14 and limiting the passage range of the conveyor 12. In other words, a function as a fixing portion for fixing the inner panel 50 with an attaching screw, and an attachment for attaching the rotating shaft base 70 having a rotating shaft 72 at the tip for supporting the inner panel 50 on the conveyor 12 side so as to be opened and closed. And function as a part. The skirt guard 26 also has a locking function for fixing the opening angle when the inner panel 50 is opened from the balustrade part 30 at a predetermined angular position.

  In the skirt guard 26, the overhanging portion 29 that projects to the upper side, that is, the handrail side angle member 38 side, is used to fix the inner panel 50 with mounting screws in the same manner as the overhang portion 39 of the handrail side angle member 38. It is a part which has a function as a fixed part. Similarly to the overhanging portion 39 in the handrail side angle member 38, the overhanging portion 29 is provided with a screw hole corresponding to the mounting hole of the inner panel 50. Further, the inner panel 50 can be firmly fixed to the skirt guard 26 by positioning the mounting hole of the inner panel 50 and the screw hole of the overhang portion 29 and screwing the mounting screw 40 into the screw hole through the mounting hole. Similarly, if the mounting screw 40 is removed, the inner panel 50 is in a free state with respect to the skirt guard 26.

  Further, the rotating shaft base 70 attached to the skirt guard 26 has a rotating shaft 72 that is a tip shaft protruding to the upper side, that is, the handrail side angle member 38 side, like the rotating shaft base 60 in the handrail side angle member 38. It is a block member. The rotating shaft base 70 is fixed to the skirt guard 26 by appropriate fixing means such as screwing or welding, or the rotating shaft 72 is a protruding shaft configured integrally with the rotating shaft base 70. This is the same as that in the angle member 38.

  The skirt guard 26 has a flange portion 28 that bends and extends in a direction parallel to the upper surface of the footboard 14. The flange portion 28 has a function of securing the strength of the skirt guard 26 and a locking function for fixing the opening angle when the inner panel 50 is opened from the balustrade portion 30 to a predetermined angular position by the fixing pin insertion hole 27. Have In other words, the opening angle when the inner panel 50 is opened from the balustrade portion 30 is made constant by inserting and locking the distal end portion 98 of the fixing pin 96 provided at the lower portion of the inner panel 50 into the fixing pin insertion hole 27. be able to.

  The fixing pin insertion hole 27 is a through hole provided in the flange portion 28 of the skirt guard 26 and having an inner diameter larger than the outer shape of the distal end portion 98 of the fixing pin 96. The position of the fixing pin insertion hole 27 is set to a position where the tip end portion 98 of the fixing pin 96 moves when the inner panel 50 is opened about 90 degrees in the moving direction of the conveyor 12, which is the direction in which the balustrade portion 30 extends. Is done. That is, when the inner panel 50 is opened at an opening angle of about 90 degrees, the tip end portion 98 of the fixing pin 96 just enters the fixing pin insertion hole 27, and the opened state of the inner panel 50 is maintained at this opening angle. The

  In addition, although the handrail side angle member 38 and the skirt guard 26 have been described as an integrated angle member having complicated bending, it may be configured as a composite member in which a plurality of members are appropriately joined.

  As shown in FIG. 2, the inner panel 50 includes a main panel portion 52 and a sub-panel portion 54 that is foldably connected to the main panel portion 52 by hinge mechanisms 82 and 83. As the hinge mechanisms 82, 83, so-called hinge members can be used in which two plate members are connected by a rotation shaft, one plate member is connected to the main panel portion 52, and the other plate member is connected to the slave panel portion 54.

  The rotary bearing portions 64 provided at the upper and lower portions of the main panel portion 52 are bearings into which the rotary shafts 62 protruding from the rotary shaft base portion 60 provided at the base portion and the top portion of the balustrade portion 30 are inserted. The rotary bearing portion 64 can be a cylindrical member having a through hole. The rotary bearing portion 64 is attached to the main panel portion 52 by appropriate fixing means such as screwing. In order to facilitate the assembly of the inner panel 50 to the balustrade part 30, the rotary bearing part 64 is preferably detachably attached to the main panel part 52.

  The bent portion 80 provided at the lower portion of the main panel portion 52 is an attachment portion for attaching the fixing pin mechanism 90. The bent portion 80 is formed by being bent substantially at a right angle to a main plane of the main panel portion 52, that is, a plane parallel to the moving direction of the conveyor 12 when fixed to the balustrade portion 30. However, the bending angle can be set to an arbitrary angle by changing the arrangement of the fixing pin insertion holes 27 provided in the flange portion 28 of the skirt guard 26.

  The fixing pin mechanism 90 is a mechanism that holds the fixing pin 96 that is urged and protrudes downward from the main panel portion 52, that is, the flange portion 28 side of the skirt guard 26. The fixed pin mechanism includes a casing 92 having a cylindrical hollow portion therein, a coil spring 94 as urging means, a receiving plate portion that receives the urging force of the coil spring 94 at one end, and a tip end portion 98 at the other end. And a fixing pin 96 having As shown in FIG. 3, the receiving plate at one end of the fixing pin 96 is guided by the inner diameter shape of the cylindrical cavity inside the housing 92 and can move in the axial direction. One end of the coil spring 94 is in contact with the upper wall of the cylindrical cavity inside the housing 92, and the other end is in contact with the receiving plate portion of the fixing pin 96.

  The natural length of the coil spring 94 is set to be longer than the axial length of the cylindrical inner cavity of the casing 92. Therefore, the fixing pin 96 always protrudes downward, that is, toward the flange portion 28 of the skirt guard 26. Energizing power is given.

  As shown in FIG. 4, when the inner panel 50 is parallel to the moving direction of the conveyor 12, which is the direction in which the skirt guard 26 extends, the position of the fixing pin mechanism 90 is different from the position of the fixing pin insertion hole 27. . Therefore, the distal end portion 98 of the fixing pin 96 is pressed against the upper surface of the flange portion 28 of the skirt guard 26 and is urged.

  As will be described later with reference to FIG. 7, when the inner panel 50 rotates about 90 degrees at the opening angle, the fixing pin mechanism 90 is set so that the position of the tip portion 98 of the fixing pin 96 is exactly the position of the fixing pin insertion hole 27. Will rotate. At this time, the tip end portion 98 of the fixing pin 96 automatically enters the fixing pin insertion hole 27 by the biasing force of the coil spring 94, and thereby the opening angle of the inner panel 50 is automatically fixed.

  As shown in FIG. 2, the sub panel portion 54 is a panel plate connected to the main panel portion 52 by the hinge mechanisms 82 and 83. The sub panel portion 54 does not have a rotary bearing portion, but instead is provided with a mounting hole through which the mounting screws 40 and 42 are passed. As described with reference to FIG. 3, the mounting hole is provided at a position corresponding to the screw hole provided in the overhang portion 39 of the handrail side angle member 38. Accordingly, when the inner panel 50 is closed, the slave panel portion 54 is unfolded with respect to the main panel portion 52, and the main panel portion 52 and the slave panel portion 54 are parallel to the moving direction of the conveyor 12, respectively. 30 can be integrated with each other.

  Next, the state of the balustrade part 30 when the maintenance work is performed will be described with reference to FIGS. 5 corresponds to FIG. 2 and shows a state where the balustrade part 30 is viewed from the conveyor side, FIG. 6 corresponds to FIG. 3, and a cross-sectional view showing how the inner panel 50 is supported in the balustrade part 30, FIG. It corresponds to FIG. 4 and is a top view about the part of rotation support, and a mode that the opened inner side panel 51 is folded is also shown. FIG. 8 corresponds to FIGS. 2 and 5 and is a view showing a state in which the inside of the balustrade portion 30 is viewed from the conveyor side when the opened inner panel 51 is folded.

  To perform maintenance work, the worker first removes the mounting screws 40 and 42 that fix the slave panel portion 54 of the inner panel 50 to the top and base of the balustrade portion 30. As a result, the inner panel 50 can be rotated around the rotating shafts 62 and 72 provided coaxially with the handrail side angle member 38 that is the top of the balustrade 30 and the skirt guard 26 that is the base.

  When the inner panel 50 is rotated about 90 degrees with respect to the direction in which the balustrade section 30 is opened by an operator, the position of the fixing pin mechanism 90 comes to the position of the fixing pin insertion hole 27. Here, the distal end portion 98 of the fixing pin 96 automatically enters the fixing pin insertion hole 27 by the action of the urging force of the coil spring 94 of the fixing pin mechanism 90. Thereby, the opening angle of the inner panel 50 is fixed thereafter.

  In FIGS. 5 and 6, a single open inner panel 51 is shown. The opened inner panel 51 is in an unfolded state in which the main panel portion 53 and the slave panel portion 55 extend straight, the entire opening angle is about 90 degrees, and the distal end portion 98 of the fixing pin 96 in the fixing pin mechanism 90. Is entering the fixing pin insertion hole 27. As shown in FIGS. 2 and 5, the inner panel 50 is entirely composed of a main panel portion 52 and a sub panel portion 54, and the main panel portion 52 is rotatably supported by rotating shafts 62 and 72. Therefore, although all the inner panels 50 can be opened, FIG. 5 shows a state where one inner panel 51 is opened for the sake of simplicity.

  7 and 8 show a state in which the main panel portion 53 is folded and the slave panel portion 57 is overlapped. Thus, by making the opened inner panel 51 into a folded state, as shown in FIG. 1, the area occupied by the inner panel 51 opened in the conveyor 12 can be reduced. Maintenance work is performed in this state. That is, the inner space 51 and the lower space 24 of the balustrade section 30 can be accessed for maintenance work from the opening opened in the balustrade section 30 by the opened inner panel 51. For example, the tension of the moving handrail drive chain 20 can be increased. It is easy to make adjustments.

  When the maintenance work is completed, the opened inner panel 51 is closed by the worker. First, the worker pushes back the distal end portion 98 of the fixing pin 96 against the urging force of the coil spring 94 and removes it from the fixing pin insertion hole 27. Thereby, the opening angle of the opened inner panel 50 can be returned to a free state. Before and after this, the sub-panel portion 54 is unfolded with respect to the main panel portion 52 and is returned to the straightly extended form. Then, the open state is returned to the closed state, and the sub panel portion 54 is firmly fixed to the top portion and the base portion of the balustrade portion 30 using the mounting screws 40 and 42.
