  First, a first embodiment of the present invention will be described with reference to FIGS. A present Example is related with the escalator which is a kind of passenger conveyor, The whole structure is as showing in FIG.

  In this escalator device 1, a large number of steps 2 are connected endlessly and circulated to transport passengers between an upper floor 31 and a lower floor 32. Further, the escalator device 1 is located on both sides in the width direction of the step 2, the frame 5 installed in the building structure, the handrail 4 provided for the safety of the passenger and moving in synchronization with the step 2. A balustrade 41 is provided that supports the handrail 4 and is erected along the longitudinal direction of the frame 5. The width direction of the step 2 refers to the longitudinal direction of the step 2, in other words, the direction perpendicular to the plane of FIG. The steps 2, handrails 4, balustrade 41, etc. are supported by the frame 5, and the building-side boarding / exiting floors (specifically, the upper floor 31 and the lower floor 32) are provided at both longitudinal ends of the frame 5. It is fixed.

  The frame 5 of the escalator device 1 includes an upper floor flat portion 11 and a lower floor flat portion 12 on which passengers get on and off, and an inclined portion 13 that connects between them. A driving machine 61 is installed in the upper floor machine room 6 in the upper floor flat part 11 to drive the driving sprocket 62. On the other hand, a driven sprocket 71 is installed in the lower floor machine room 7 in the lower floor flat portion 12, and an endless chain 8 is continuously wound around the upper and lower drive sprockets 62 and the driven sprocket 71. It comes to drive.

  An axle 8A is connected to the chain 8 at equal intervals, and a bearing 8B that supports the axle 8A is attached to each step 2. Further, the weight of the step 2 and the load received by the tread are finally supported by a guide rail (not shown) via a chain shaft wheel (front wheel) 9 and a step wheel (rear wheel) 10, and this guide rail Step 2 travels along.

  Next, FIG. 2 is an enlarged view showing the configuration of the step 2 in the present embodiment. Here, the meaning of the term “step” in this specification includes those in an escalator and those in a moving sidewalk. In this embodiment, the step 2 used in the escalator will be described.

  The step 2 in this embodiment includes a cleat 2A that forms a tread surface, cautions D1 and D2 that are arranged at the end of the cleat 2A to alert the passenger, and a riser 2R that blocks a step between the adjacent step 2. The main frame body 20 to which these are assembled is mainly configured.

  Here, the cleat 2A is formed by bending a thin steel plate such as stainless steel into a wave shape, and a plurality of reinforcing bodies 2B1, 2B2, and 2B3 are attached to the back side thereof by welding or an adhesive, and the cleat 2A and each reinforcing body. And the cleat portion 2C. The reinforcing bodies 2B1, 2B2, and 2B3 are formed of a continuous body having a hat-shaped (hat-shaped hat-shaped) cross section in the width direction of the step 2.

  On the other hand, the main frame 20 in the present embodiment is manufactured by a method such as extrusion using aluminum or the like as a material, and is formed as a continuous body having substantially the same cross-sectional shape in the width direction of the step 2. In addition, if it is going to manufacture this continuous body of substantially the same cross-sectional shape by aluminum die casting, since an installation will become enormous, it is not very suitable. In addition, locking portions 20a, 20b, 20c, 20d, 20e, 20f, 20k, and 20L are provided at the upper end of the main frame 20. For this reason, by inserting the edge portions of the reinforcing bodies 2B1, 2B2, and 2B3 into the gaps between the locking portions 20a, 20b, 20c, 20d, 20e, and 20f and sliding them in the width direction of the step 2, the cleat portion 2C Can be easily assembled to the main frame 20.

  Further, a convex portion (for example, a convex portion 21 between the pair of locking portions 20a and 20b) is provided at the upper end of the main frame 20 and between the pair of locking portions. It abuts against the inner surfaces of the reinforcing bodies 2B1, 2B2, and 2B3 and supports the load of passengers and the like applied to the upper surface of the cleat 2A. The cross section in the width direction of the main frame 20 has members 21A, 21B, 22A, 22B, 23A, and 24 that extend radially upward from positions near the extension line of the wheel shaft. For this reason, first, the load applied to the convex portion 21 is mainly transmitted to the rear wheel 10 via the members 21A and 21B extending downward from the vicinity thereof, and is finally supported by the guide rail. Secondly, the load applied to the convex portion 22 is mainly transmitted to the rear wheel 10 and the front wheel 9 via members 22A and 22B extending downward from the vicinity thereof, and is finally supported by the guide rail. Third, the load applied to the convex portion 23 is mainly transmitted to the front wheel 9 via the member 23A extending downward from the vicinity thereof, and is finally supported by the guide rail. When the adhesive or adhesive tape is attached between the outer surfaces of the convex portions 21, 22, 23 and the inner surfaces of the reinforcing bodies 2B1, 2B2, 2B3, the cleat portion 2C and the main frame 20 are fixed. It becomes even stronger.

  Next, the riser 2R in the present embodiment is formed by bending a thin steel plate such as stainless steel into a wave shape, and a plurality of reinforcing bodies 2R1, 2R2, 2R3 are attached to the back side thereof by welding or an adhesive, etc. And the reinforcements are integrated to form the riser portion 2V. The reinforcing bodies 2R1, 2R2, and 2R3 are formed as a continuous body having a Z-shaped cross section in the width direction of the step 2.

  On the other hand, the member 21B that forms the rear end of the main frame 20 is provided with locking portions 20g, 20h, and 20j. Therefore, a part of the reinforcing bodies 2R1, 2R2, and 2R3 is inserted into the gaps between the locking portions 20g, 20h, and 20j, and is slid in the width direction of the step 2 so that the riser portion 2V can be easily moved to the main frame body 20. Can be assembled.

  In addition, the caution bodies D1 and D2 in this embodiment are installed at both ends of at least the traveling direction (depth direction) of the cleat portion 2C. Here, the attention body D1 is attached by being inserted into a clearance between the locking portion 20k provided in front of the upper end of the main frame 20 and a clearance between the front end 2c1 of the cleat portion 2C. Similarly, the caution body D2 is attached by being inserted into a clearance between the locking portion 20L provided behind the upper end of the main frame 20 and a clearance between the rear end 2c2 of the cleat portion 2C.

  FIG. 3 is a perspective view showing a width direction end (side end) of the step 2 in the present embodiment. As shown in FIG. 3, the shaft SH is inserted into the hole 20H at the lower end of the main frame 20, and the rear wheel 10 is attached to the end of the shaft SH. Further, a stopper body 2H1 is provided at a side end portion of the cleat portion 2C, and a stopper body 2H2 is provided at a side end portion of the riser portion 2V. By these stopper bodies 2H1 and 2H2, the movement in the width direction of the cleat portion 2C and the riser portion 2V is suppressed, and it is possible to prevent positional deviation. The stopper body 2H1 may also serve as a caution body.

  Next, FIG. 4 shows an example of a fixing method of the stopper bodies 2H1 and 2H2. As shown in FIG. 4, the stopper body 2H1 is fixed to the convex portions 21, 22, and 23 at the upper end of the main frame body 20 by screws N1 and nuts N2. Similarly, the stopper body 2H2 is also fixed to a member 21B that forms the rear end of the main frame body 20 with screws N1 and nuts N2.

  FIG. 5 is a view as seen from I in FIG. 2. As apparent from the front view of the step 2, the main frame 20 of the present embodiment is continuous in the width direction. It differs greatly from a conventional main frame formed only at both ends. By forming the main frame 20 as a continuous body as in the present embodiment, it is possible to expect the effect of dispersing the load applied to the tread surface and avoiding stress concentration.

  FIG. 6 shows an example in which the cleat portion 2C, the riser portion 2V, and the attention bodies D1, D2 are screwed to the main frame body 20. In addition, convex portions 201, 202, and 203 are formed at the upper end of the main frame body 20, and the concave portion on the back side of the cleat portion 2C is fitted into this portion, so that the positioning is accurately performed in the traveling direction of the step 2. it can. Similarly, convex portions 204 and 205 are formed at the rear end of the main frame body 20, and the concave portion on the back side of the riser portion 2V can be fitted into this portion for accurate positioning. When the positioning is completed, the cleat portion 2C and the riser portion 2V are fixed to the main frame body 20 with screws.

  Thus, in the step 2 in this embodiment, since the main frame 20 is formed of a continuous body having substantially the same cross-sectional shape, the number of parts and screw tightening points are small, and the step 2 is assembled in a short time. be able to. In addition, if the parts of the step 2 are damaged after the escalator is installed, the parts can be easily replaced on site without special jigs or employment, so it is necessary to take them to a specialized factory. And saves time and money.

  By the way, the current mainstream width of the escalator tread is 1000 mm, but there are 600 mm and 800 mm when the number of buildings and the number of customers are small. However, in this embodiment, since the main frame 20 is formed of a continuous body having substantially the same cross-sectional shape, the width of the main frame 20 can be easily reduced by cutting it according to the required length. Can change. Therefore, it becomes easy to provide a passenger conveyor step having a wide variety of widths.

  Furthermore, since the main frame 20 of the present embodiment is configured by the radially extending members 21A and the like, the cross section in the width direction of the step 2 has a plurality of cavities 20H1, 20H2, 20H3, and 20H4. Even if the main frame 20 is formed of a continuous body having substantially the same cross-sectional shape, it is possible to suppress an increase in the overall weight.

  Next, the moving sidewalk which is the 2nd Example in this invention is demonstrated using FIG. 7, FIG. FIG. 7 shows the overall configuration of this embodiment, and FIG. 8 shows details of the steps 2 of this embodiment.

  Unlike the first embodiment, the step 2 of the present embodiment does not have the riser portion 2V. However, like the first embodiment, the main frame body is a continuous body having substantially the same cross-sectional shape in the width direction of the step 2. 20 is formed. Moreover, since the main frame 20 has the locking portions 20a, 20b, 20c, 20d, 20e, and 20f for locking the reinforcing bodies 2B1, 2B2, and 2B3, the cleat portion 2C can be easily assembled. . Therefore, it is possible to provide a passenger conveyor step that is not only high in productivity but also easy to replace on-site and has good maintainability. Also, there are various widths of the tread of the moving sidewalk depending on the installation environment, for example, there are some that are widened to about 1600 mm, but the width of the step 2 of this embodiment is easy to change. It is easy to meet such needs.
