It may be possible to rotate the main body so that the upper side of the main body is on the lower side while being supported on the lower side of the upper closing portion.

  In this case, in a state where the skirt guard is lifted from the normal position and the shaft member is supported by the upper closing portion, the main body portion of the skirt guard is rotated with the shaft member as a fulcrum so that the upper side of the main body portion becomes the lower side. Thus, the lower end portion of the main body portion can be accommodated in the skirt guard distal end portion accommodating groove. Therefore, since the skirt guard can be erected simply by lifting and rotating the skirt guard until it cannot move, work efficiency can be greatly improved.

  Further, in the present invention, the skirt guard has a pair of projecting portions that project from a back side surface of the main body portion opposite to the step side and are spaced from each other, and the shaft member includes the shaft member, It may be provided between the pair of protrusions in a state of being spaced from the back side surface.

  In this case, the shaft member can be provided on the back side surface of the skirt guard with a simple configuration. Therefore, the manufacturing cost can be reduced.

  Further, in the present invention, the skirt guard is fixed to an object to be fixed at a lower part than the skirt guard mounting angle, and further includes a lower skirt guard mounting angle having an upper protruding portion protruding upward, and the skirt guard is in the normal state. The main body portion may have an accommodating recess for accommodating the upper protruding portion on the side opposite to the step side.

  In this case, the accommodation recess of the skirt guard is supported by the upper protrusion of the lower skirt guard mounting angle in a normal state. Therefore, the posture of the skirt guard in the normal state can be stabilized, and the skirt guard can be prevented from contacting the step in the normal state.

  According to the skirt guard mounting structure according to the present invention, when performing maintenance of the members outside the skirt guard, there is no need to secure a place for the skirt guard and no need to carry the skirt guard. Can be improved.

  3 and 4, the length in the X direction between the pair of protrusions 60 is longer than the dimension in the X direction of the skirt guard mounting angle 30 (see FIG. 3). As a result, the shaft member 47 can be housed in the skirt guard shaft housing groove 41 of the skirt guard mounting angle 30.

  Next, how to operate the skirt guard 12 when performing maintenance on the members outside the skirt guard 12 will be described with reference to FIGS.

  First, referring to FIGS. 1 and 2, the mounting screw 22 that fixes the inner deck 13 to the inner deck fixing angle 15 is removed from the inner deck 13, and the inner deck 13 is removed from the inner deck fixing angle 15. Thereafter, the removed inner deck 13 is carried to the vicinity of the entrance / exit on the upper end side or the lower end side of the escalator.

  Subsequently, the skirt guard 12 exposed to the outside from the lower end to the upper end by removing the inner deck 13 is removed from the position facing the side of the step 10 in the procedure shown in FIG.

  Specifically, the skirt guard 12 is lifted upward in the depth direction Z from the normal state where the skirt guard 12 faces the side of the step, as shown in FIG. Then, as shown in FIG. 5B, the upper protrusion 42 of the lower skirt guard mounting angle 31 is detached from the housing recess 63 of the recess defining protrusion 52, and the shaft member 47 of the skirt guard 12 is moved to the skirt guard shaft. The shaft member 47 is brought into contact with the upper closing portion 37 by being moved upward in the depth direction Z within the housing groove 41.

  Subsequently, the main body portion 46 is indicated by an arrow C in FIG. 5B so that the lower side of the main body portion 46 becomes the upper side with the shaft member 47 as a fulcrum while the shaft member 47 is supported by the upper closing portion 37. Rotating in the direction, the lower end of the main body 46 is received in the skirt guard tip receiving groove 40. As shown in FIG. 5, it is preferable that the shape of the lower side of the upper closing portion 37 is a curved shape (a cross-sectional arc shape) corresponding to the shaft member 47 because the main body portion 46 can be smoothly rotated. Or a planar shape or the like. In this case, the main body 46 may be rotated without using the shaft member 47 as a fulcrum, or the main body 46 may be received while the shaft member 47 is received at the bottom of the skirt guard shaft housing groove 41. What is necessary is just to rotate the part 46. FIG.

  Thereafter, as shown in FIG. 5C, when the lower end portion 57 of the main body portion 46 is accommodated until it contacts the bottom portion 59 on the lower side of the skirt guard distal end portion accommodating groove 40, the skirt guard 12 becomes skirt guard 12. It will be in the state which stood up from the downward side of the front-end | tip part accommodation groove | channel 40 in the depth direction Z upper side. In the state where the skirt guard 12 shown in FIG. 5C stands, the shaft member 47 is disposed below the passage 38 connecting the two grooves 40 and 41 and is sandwiched between both side surfaces of the skirt guard shaft receiving groove 41. The structure is such that it hardly moves in the thickness direction Y. In the state where the skirt guard 12 shown in FIG. 5C is raised, the end 64 on one side in the depth direction Z located on the lower side of the skirt guard 12 in the normal state shown in FIG. Is located above the depth direction Z.

  The skirt guard tip portion receiving groove 40 has a shape corresponding to the main body portion 46 of the skirt guard 12 and has a dimension in the thickness direction Y slightly larger than the thickness of the main body portion 46 of the skirt guard 12. In this way, the skirt guard 12 is fitted in a state in which the main body 46 of the skirt guard 12 is in close contact with the skirt guard tip receiving groove 40, and the skirt guard 12 is raised while the skirt guard 12 is standing up. It is prevented from coming off from the accommodation groove 40. In particular, the tip of the skirt guard 12 of the skirt guard 12 is fitted into the skirt guard tip receiving groove 40 and received from below, and the shaft member 47 is fitted into the skirt guard shaft receiving groove 41 and received by the inner surface of the groove ( The configuration in which the shaft member 47 is received from the lower side of the groove is more preferable), and the skirt guard 12 can be held independently by its own weight.

  In the state shown in FIG. 5 (c), the skirt guard 12 stands up from the lower side of the skirt guard tip receiving groove 40 in the depth direction Z, leading to the outside of the side of the step 10. A large opening occurs. Maintenance of members disposed outside through this opening, for example, a drive-side sprocket and a pressure roller, can be performed.

  The passage 38 connecting the two grooves 40 and 41 is used when the skirt guard 12 is replaced. That is, the skirt guard 12 may be scraped by contact with the step 10 and may need to be replaced. When the skirt guard 12 is replaced, for example, the main body 46 is rotated in the direction indicated by the arrow C from the state shown in FIG. 5B until the main body 46 is substantially parallel to the ramp. Subsequently, the shaft member 47 passes through the passage 38 and is positioned in the skirt guard tip portion receiving groove 40. After that, when the shaft member 47 is moved upward in the depth direction Z in the skirt guard tip receiving groove 40 and detached from the skirt guard tip receiving groove 40, the skirt guard 12 is removed from the skirt guard mounting angle 30. .

  According to the above embodiment, the skirt guard 12 is rotated from the normal position so that the upper side of the main body portion 46 is on the lower side, whereby the lower end portion of the main body portion 46 is received in the skirt guard tip portion receiving groove 40. As a result, the skirt guard 12 can be raised upward from the skirt guard tip portion receiving groove 40. Then, the skirt guard 12 can be removed from the position facing the side of the step 10 only by raising the skirt guard 12 upward from the skirt guard tip portion receiving groove 40. Therefore, it is not necessary to remove the skirt guard 12 from the skirt guard mounting angle 30, and it is not necessary to carry the skirt guard 12 to the skirt guard place. As a result, maintenance workability can be improved.

  Further, in a state where the skirt guard 12 is lifted from the normal position and the shaft member 47 is supported by the upper closing portion 37, the upper side of the main body portion 46 is directed downward with the main body portion 46 of the skirt guard 12 as a fulcrum. Thus, the lower end portion 57 of the main body portion 46 can be accommodated in the skirt guard distal end portion accommodating groove 40. Therefore, the skirt guard 12 can be erected simply by lifting and rotating the skirt guard 12 until it cannot move, so that the work efficiency can be greatly improved.

  Furthermore, in the state where the skirt guard 12 shown in FIG. 5C is raised, the skirt guard tip portion receiving groove 40 in which the lower side of the skirt guard 12 is accommodated has a depth direction Z (one direction including a vertical direction component). ), The skirt guard 12 is not easily detached from the skirt guard tip portion receiving groove 40 even when a pitch is caused by an earthquake. 5C, the main body 46 of the skirt guard 12 is sandwiched between both side surfaces of the skirt guard tip receiving groove 40, and the shaft member 47 is also housed in the skirt guard shaft. The skirt guard 12 is not detached from the skirt guard mounting angle 30 even when rolling occurs due to an earthquake because the groove 41 is sandwiched between both sides.

  In addition, this invention is not limited to the said embodiment and its modification, A various improvement and change are possible in the matter described in the claim of this application, and its equivalent range.

  For example, in the above-described embodiment, the skirt guard 12 is merely fixed to an angle fixed to an object to be fixed such as a steel frame, and is not fixed by a fastening member or the like. However, the skirt guard 12 may be fixed by a fastening member to an angle fixed to an object to be fixed such as a steel frame.

  The case where the skirt guard mounting structure 50 has the lower skirt guard mounting angle 31 below the skirt guard mounting angle 30 has been described. However, the skirt guard mounting structure may not have the lower skirt guard mounting angle below the skirt guard mounting angle.

  Moreover, although the case where the escalator 1 which is a passenger conveyor has the inner deck 13 was demonstrated, the escalator does not need to have an inner deck. Moreover, although the case where the passenger conveyor is the escalator 1 has been described, the passenger conveyor may be a moving sidewalk in which a plurality of steps on which passengers ride are connected in the horizontal direction. In addition, when the passenger conveyor is a moving sidewalk, it goes without saying that the depth direction in which the skirt guard tip receiving groove extends substantially coincides with the vertical direction.
