Description

  The present invention relates to passenger conveyors such as escalators and steps of passenger conveyors, and more particularly to the structure of riser side end demarcation provided at the right and left ends of the riser of the steps.

  A passenger conveyor such as an escalator is generally provided with a riser that covers a step generated between adjacent steps on a step that is connected endlessly between the getting-on / off floors and circulates. In general, the riser 20 is welded to riser bases 22 and 23 arranged above and below (up and down) the step 14 as shown in FIG. 2 showing a front view of the step and FIG. 3 showing a side view of the step. The left and right ends of the riser 20 are provided with resin riser side end demarcation 21 colored in yellow or the like for the purpose of alerting passengers. The application 21 is fixed to the riser bases 22 and 23 by fixing screws 24. In addition, a gap is provided between the front and rear steps 14 to prevent mutual interference. From the viewpoint of preventing pinching, the Building Standard Law defines the gap as 5 mm or less. Further, the riser 20 of the step must not be easily deformed or damaged even when a foreign object is caught between the steps 14, and needs a certain degree of rigidity in the traveling direction of the escalator. Therefore, the riser 20 is generally formed of a stainless steel plate having a thickness of about 0.5 mm and is integrally formed so that the pier and the pier are continuous, and the riser bases 22 and 23 having a thickness of about 2.5 mm are formed. It is welded.

  However, in the prior art, as shown in FIG. 7 which is an enlarged cross-sectional view showing the upper and lower portions of the riser, the upper and lower portions of the riser 20a are supported by the riser bases 22a and 23a on the back surface. Therefore, although sufficient rigidity can be secured, there is no riser base in the vicinity of the central portion in the height direction, that is, the region indicated by H in FIGS. 2 and 3, and the cross-sectional enlarged view showing the central portion in the height direction of the riser As shown in FIG. 8, it is necessary to ensure the rigidity of the riser 20 a alone, and the left and right end portions in this region are piers and are flat and have low rigidity. Therefore, as shown in FIG. 9, when a thin foreign object 25a such as an umbrella tip is sandwiched between the riser 20a and the riser side end demarcation 21a, the riser 20a may be deformed. A passenger's clothes etc. were drawn in to the generated opening W, and there was a danger of leading to a big accident.

  Further, a step chain that is stretched in a pair of left and right may cause a difference in lateral growth due to a difference in passenger load on the step 14, and the step 14 may run diagonally. The rear end side (riser side) may be swung to the left or right, and the riser side end demarcation 21 may contact the skirt guard 16 disposed on the side of the step 14. In particular, when the skirt guard 16 collides with a seam step, the riser side end demarcation 21 may be damaged or the end of the riser 20 may be deformed by a strong impact force. Damage to the riser side end demarcation 21 can be replaced with a new one just by loosening the fixing bolt 24. However, if the end of the riser 20 is deformed, the set of steps 14 must be replaced. It has been desired to improve the rigidity of the left and right end portions.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide a passenger conveyor and a passenger conveyor step that can improve the rigidity of the left and right ends of the riser.

A step chain that circulates and has a step shaft attached thereto, a step that is rotatably attached to the step shaft, and a balustrade erected on the frame body on both sides along the moving direction of the step, Riser side end demarcation in which the step has a riser portion that covers a step between a cleat on which a passenger rides and an adjacent step, and the riser portion is arranged at the right and left ends of the riser. And a riser base that is disposed above and below the steps, and to which the riser and the riser side end demarcation are attached, Is characterized in that a engagement portion for engagement with part.

  In addition, the present invention has a riser portion that is connected endlessly between the getting-on / off floors and circulates and covers a step between a cleat on which a passenger rides and an adjacent step, and the riser portion is a riser, Riser side end demarcation disposed at the left and right end portions of the riser, and a step of a passenger conveyor comprising a riser base that is disposed above and below the step and to which the riser and the riser side end demarcation are attached, The riser side end demarcation is provided with engaging portions that engage with the left and right ends of the riser.

  In this invention comprised in this way, the right-and-left end part of a riser can be engaged with the engaging part of a riser side end demarcation, and the rigidity of the front-back direction of a riser left-right end part can be improved.

  Further, according to the present invention, the pitch dimension between the ridges of the riser and the pitch dimension from the ridge of the outermost end of the riser to the pier of the riser side end demarcation is L1, and When the width direction dimension to the left and right ends is L2, the dimensional relationship is L2> L1.

  In the present invention configured as described above, the left and right end portions of the riser overlap and engage with the riser side end demarcation by the amount of L2-L1, so that the rail between the outermost ridge and the riser side end demarcation. Even when a thin foreign object such as an umbrella tip is caught in the valley, the riser is hardly deformed, and deformation of the riser can be suppressed to a minimum and an opening can be prevented.

  Furthermore, the present invention is such that the plate thickness of the riser base is thicker than the plate thickness of the riser, the widthwise gap between the left and right end portions of the riser and the riser side end demarcation is L3, and the left and right end portions of the riser base When the gap in the width direction of the riser side end demarcation is L4, the dimensional relationship is L3> L4.

  In the present invention configured as above, even if the riser side end demarcation and the balustrade panel are in contact with each other and the fixing bolt is deformed and the riser side end demarcation is displaced, the impact force is applied to the riser base of a relatively thick plate. By receiving, it can prevent that a right-and-left end part of a riser changes.

  According to the present invention, it is possible to improve the rigidity of the left and right end portions of the riser and reduce the deformation of the left and right end portions of the riser due to an external force, thereby improving safety and reducing maintenance costs.

  Embodiments of passenger conveyors and steps of passenger conveyors according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a passenger conveyor, for example, an escalator device 1 is arranged at a frame body 4 that is installed across the upper floor 2 and the lower floor 3 of a building structure, and at both longitudinal ends of the frame body 4. The upper machine room 5 and the lower machine room 6 are installed in the upper and lower landing floors 8 and 8 and the machine rooms 5 and 6 that block the machine rooms 5 and 6 from above. Upper terminal sprocket 9 and lower terminal sprocket 10, a pair of left and right step chains 11 wound endlessly around these terminal sprockets 9, 10, a step shaft 12 connecting the left and right step chains 11, and a step shaft 12 A front wheel 13 provided at both ends of the door, a step 14 rotatably attached to the step shaft 12, a terminal sprocket 9, 10 and a step checker installed in the upper machine room 5. A driving device 15 that rotates the step 14 via the rail 11, a balustrade panel 26 that is erected on the frame 4 opposite to each other along the moving direction of the step 14, and a peripheral edge of the balustrade panel 26 And a handrail 17 that is driven in synchronization with the step 14. A skirt guard 16 is provided on the side of the step 14 with a predetermined gap from the step 14.

  As shown in FIG. 2, which is a front view, the step 14 includes a cleat 18 on which a passenger rides and a riser portion 19 that covers a step generated between adjacent steps.

  The riser unit 19 is arranged above and below the step 14 as shown in FIG. 3 which is a side view, and a riser side end demarcation 21 arranged at the right and left ends of the riser 20. 20 and a riser base 22 and 23 to which a riser side end demarcation 21 is attached.

  The riser side end demarcation 21 is fixed to the riser bases 22 and 23 via fixing screws 24.

  And the passenger conveyor of a present Example and the step of a passenger conveyor are shown in FIG. 4 which is an AA section cross-sectional enlarged view of FIG. An engaging portion 21A to be engaged is provided. By providing and engaging the engaging portion 21A in this way, the rigidity in the front-rear direction of the left and right end portions of the riser can be increased.

  Further, the pitch dimension between the ridges of the riser 20 and the pitch dimension from the ridge of the uppermost end of the riser 20 to the pier of the riser side end demarcation 21 are L1, and the right and left of the riser 20 from the pier of the uppermost end of the riser 20 When the dimension in the width direction to the end is L2, the dimension relationship is L2> L1. Note that the inter-mountain pitch dimension in the riser side end demarcation 21 is also L1.

  Further, as shown in FIG. 5 which is a cross-sectional enlarged view of the B-B portion of FIG. 3, the gap in the width direction between the left and right end portions of the riser 20 and the riser side end demarcation 21 is L3, When the gap in the width direction of the riser side end demarcation 21 is L4, the dimensional relationship is L3> L4. The plate thickness of the riser bases 22 and 23 is made larger than the plate thickness of the riser 20.

  According to the present embodiment, the pitch dimension between the piers of the riser 20 and the pitch dimension from the pier at the outermost end of the riser 20 to the pier at the riser end demarcation 21 are L1, and the pier at the outermost end of the riser 20. When the dimension in the width direction from the end of the riser 20 to the end of the riser 20 is L2, the left and right end of the riser overlaps and engages with the riser side end demarcation by the amount of L2-L1 by satisfying the dimensional relationship of L2> L1. Therefore, as shown in FIG. 6, the riser 20 is deformed even when a thin foreign object 25 such as the tip of an umbrella is caught in the valley between the outermost peak of the riser 20 and the riser side end demarcation 21. It becomes difficult, the deformation of the riser 20 can be minimized, and the occurrence of an opening as in the conventional case can be prevented.

  Note that the pitch dimension between the ridges of the riser 20 and the pitch dimension from the ridge at the outermost end of the riser 20 to the ridge at the riser side end demarcation 21 are both set to L1. This is because, and the pitch dimension of the front end demarcation or the side end demarcation of the adjacent step 14 meshing with this pier and pier is also L1.

  In addition, the step chain 11 stretched as a pair on the left and right side may cause a difference in aging due to a difference in passenger load on the step 14, and the step 14 may travel diagonally. The rear end side (riser side) may be swung left or right, and the riser side end demarcation 21 may contact the skirt guard 16. In particular, when it collides with the seam level difference 16A of the skirt guard 16, a strong impact force is applied. However, when the width direction gap between the left and right end portions of the riser 20 and the riser side end demarcation 21 is L3, and the width direction gap between the left and right end portions of the riser bases 22 and 23 and the riser side end demarcation 21 is L4, L3> Due to the dimensional relationship of L4, even if the fixing bolt 24 is deformed by the impact force described above and the riser side end demarcation 21 is displaced, the impact force is generally formed of a relatively thick plate of about 2.5 mm. Since it can be received by the riser bases 22 and 23 that are thicker than the plate thickness of the riser 20, it is possible to prevent the end of the riser 20 from being deformed.

  According to the present embodiment, the rigidity of the left and right end portions of the riser 20 can be improved, and deformation of the riser end portion due to external force can be reduced, thereby improving safety and reducing maintenance costs.
