Embodiment 1 FIG.
1 to 3 are diagrams for explaining a step device for a man conveyor according to Embodiment 1 of the present invention. FIG. 1 is a sectional view showing a main part of the step, and FIG. 2 is an operation when a load is received on the step. FIG. 3 is a perspective view partially showing an external configuration of an escalator using the step of FIG. 1 corresponds to a cross-sectional view taken along the line II in FIG. In the figure, the step 1 includes a step plate 11 formed with a large number of grooves 11a and a step surface 11b formed in parallel with the traveling direction, and both end portions of the step plate 11 (only the left end portion is shown). It has the notch step part 12 formed over the full length of the advancing direction. In the example shown in the drawing, the notch step portion 12 is formed by cutting away the upper portions of both side end portions of the tread plate 11, but the present invention is not limited thereto. The bottom plate 12a of the notch step portion 12 may be made of another member such as a frame member (not shown), for example.

  An elastic member 3 made of, for example, plastic rubber or the like in which a groove 3a and a tread surface 3b similar to the tread plate 11 are formed on the inner side of the notch step portion 12 (the center in the width direction of the step 1, the right side in FIG. 1). The lower surface is the sliding surface 4a, the upper surface is the tread surface 4b, and the surface facing the outer step guard member 2 is the sliding surface 4c. A sliding body 4 made of a formed plate-like hard material is provided. Examples of the hard material include various metal materials such as stainless steel, copper, aluminum, and alloys thereof, resin materials such as fluororesin, and composite materials such as carbon fiber reinforced resin (FRP). A hard material that is small or can be easily slid between the step guard member 2 with the aid of a lubricant or the like can be appropriately selected and used without any particular limitation, but is not limited to these exemplified materials. . In this example, the depths of the grooves 11 a and 3 a and the levels of the tread surfaces 11 b, 3 b and 4 b are substantially constant, and the upper surface is formed flat so as to be continuous with the tread plate 11.

  The elastic member 3 has an adhesive or the like at a corner portion where the central portion side (the right side in the figure) extends from the lower half of the side wall 12b of the notched step portion 12 of the tread 11 to the right end portion of the bottom surface 12a of the notched step portion 12. The lower portion of the outer surface is mainly bonded only to the inner surface of the sliding body 4 by an adhesive means 5b such as an adhesive, and the bottom surface 12a of the notched step 12 is It is provided to be extensible in the outer direction (left direction in the figure). Note that the elastic member 3 and the sliding body 4 constitute a tread board side end member 6 connected to the tread board 11, and the tread board side end member 6 can be colored yellow for alerting.

  The step guard member 2 is fixed to a reinforcing angle 21 provided at a position invisible from the outside, and a gap t is formed between the inside of the step guard member 2 and the step 1. As is well known to those skilled in the art, a predetermined number of steps 1 are connected in an endless loop shape via a drive chain (not shown), and in the case of forming an escalator, a kick-up portion 1a is provided as shown in FIG. The step 1 is configured in a step shape and is configured to travel inside the step guard member 2 disposed on both sides in the traveling direction. 2 shown in FIG. 2 is a passenger's shoes, and 8 shown in FIG. 3 is a moving handrail. The same reference numerals denote the same or corresponding parts throughout the drawings.

  Next, the operation of the first embodiment configured as described above will be described. First, at the time of stopping or driving, in a normal state in which the load through the passenger's shoes (footwear) or the like is not on the tread board side end members 6 at both end portions of the step 1, as shown in FIG. 6, the tread surface 3b of the elastic member 3 and the tread surface 4b of the sliding body 4 are formed in a flat shape at substantially the same height as the tread surface 11b of the tread 11 in the center, and the sliding of the sliding body 4 A gap t is formed between the surface 4 c and the step guard member 2. Therefore, the step 1 is driven without receiving excessive resistance due to sliding, and no excessive noise is generated.

  On the other hand, when the passenger puts his / her foot on the tread board side end member 6 provided at the side end portion of the tread board 11 and takes weight through the shoes 7, the elastic member 3 is in the direction of gravity indicated by the arrow B in FIG. Compressive deformation in the vertical direction due to the load. At the same time, the deformation of the right end portion of the elastic member 3 in the figure is constrained by the side wall 12b of the notch step portion 12 of the tread plate 11, and the lower surface A portion and the sliding body 4 can freely slide in the left-right direction, The elastic member 3 expands in the outer direction indicated by the arrow C by the compression and presses the sliding body 4 against the inner surface of the step guard member 2 so that the gap t is closed. The vehicle travels while being in contact with the inside of the member 2.

  At this time, since the sliding body 4 is made of a hard material, the sliding body 4 does not sink downward, prevents an object from being caught in the gap, and at the same time, creates a step between the sinking elastic member 3 and the tread surface 3b, The shoe 7 is prevented from moving in the direction of the outer step guard member 2. Further, when a load is applied only to the tread surface 4b of the sliding body 4, the sliding body 4 can be tilted to the outside (left direction in the figure) because it is bonded only to the elastic member 3 at the bottom. Thus, the gap t is blocked, thereby preventing pinching and pull-in. Furthermore, since the sliding body 4 is made of a hard material, the coefficient of friction is smaller than that of a soft material such as rubber, and the contact is made smoothly, so damage to the step guard member 2 (occurrence of scratches) is caused. Is prevented. In addition, the selection of the material is easy.

  As described above, according to the first embodiment, the cutout step portion 12 is brought into contact with the elastic member 3 that is deformed outward by a load from above and the step guard member 2 by deformation of the elastic member 3. By providing the tread board side end member 6 made of the sliding body 4 made of a hard material that moves to the elastic member 3, the elastic member 3 is deformed laterally outward when a load is applied to the elastic member 3 via the shoe 7 of the passenger. Then, by moving the sliding body 4 to the outside, the gap between the step 1 and the step guard member 2 can be eliminated to prevent the passenger's feet, shoes 7 and the like from being caught or pulled in.

  Further, since the sliding body 4 is arranged on the outermost surface of the step 1, when the gap t between the step guard member 2 and the step 1 becomes zero, it is possible to make the contact smooth, Damage to the step guard member 2 can be prevented. Further, the elastic member 3 is compressed and deformed downward by a load received from the passenger's shoes 7 and the like, whereas the sliding body 4 is made of a hard material. Therefore, when the elastic member 3 receives a load, the mutual tread 3b. And 4b, the end sliding body 4 protrudes relatively, and there is an effect that the movement of the passenger's shoes 7 and the like in the direction of the step guard member 2 can be restricted. In addition, since the configuration is simple, manufacturing is easy and can be provided at low cost.

Embodiment 2. FIG.
4 and 5 illustrate a man conveyor stepping device according to Embodiment 2 of the present invention. FIG. 4 is a cross-sectional view showing the main part of the step, and FIG. 5 shows a load applied to the step of FIG. It is sectional drawing explaining operation | movement of. In the figure, a tread plate side end member 6 provided in the notch step portion 12 is made of a hard material such as metal having a groove 9a and a tread surface 9b, and is provided so as to be movable up and down with respect to the tread plate 11. A plate-like elastic member 30 provided between the movable tread plate 9 and the bottom surface 12a of the notch step portion 12, and a laminated plate 31 disposed vertically so as to sandwich the elastic member 30 in a sandwich shape, 32 and the sliding body 4, the right end portion of the elastic member 30 in the figure is bonded to the side wall 12 b of the notch step portion 12 by an adhesive means 5 a made of an adhesive, and the left end portion is inside the sliding body 4. It is bonded to the surface by bonding means 5b made of the same adhesive.

  The laminated plates 31 and 32 are composite materials in which an elastic material such as rubber is sandwiched between metal plates such as stainless steel and iron plates, and is an integrated composite material. In this example, the elastic members 30 are stacked one above the other. The laminated plates 31 and 32 are not necessarily indispensable because the effects of the present invention can be expected even if they are omitted, but one is inserted between the elastic member 30 and the movable tread plate 9, or as shown in FIG. Thus, since the elastic member 30 can be easily deformed by inserting the elastic member 30 one by one above and below the elastic member 30, it is desirable to insert at least one elastic member 30 in order to ensure the operation. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  In the second embodiment configured as described above, when the movable tread 9 receives a load in the direction of arrow B in FIG. The load can be applied to the elastic member 30 evenly, and the elastic member 30 is deformed in the outer direction indicated by the arrow C by the load, and the sliding body 4 is bonded only to the elastic member 30, thereby The moving body 4 can be efficiently moved in the direction of the step guard member 2 (left direction in the figure).

  For this reason, the gap t between the step 1 and the step guard member 2 can be effectively narrowed according to the load. Although the movable tread 9 is made of a hard material, the elastic member 30 sinks downward due to being interposed between the bottom surface 12 a and the tread 4 b of the sliding body 4 and the tread 9 b of the movable tread 9 are interposed. A step similar to that of the first embodiment is generated, and the movement of the shoe 7 and the like in the direction of the outer step guard member 2 is similarly prevented, and the gap t becomes zero, so that the pinch and the pull-in can be prevented. An effect is obtained.

  In the description of the above embodiment, the case where an adhesive is used as the bonding means 5a and 5b is exemplified. However, the bonding means 5a and 5b are not limited to the adhesive. It can be changed to other bonding means such as a mating structure and a mating structure. Moreover, although the case where this invention was applied to the escalator as a man conveyor was demonstrated, it cannot be overemphasized that it can use similarly for other man conveyors, such as a moving sidewalk.

It is sectional drawing which shows the principal part of the step in the step apparatus of the man conveyor by Embodiment 1 of this invention. In addition, it corresponds to a cross-sectional view taken along line II in FIG. It is sectional drawing explaining operation | movement when a load is received in the step shown in FIG. It is a perspective view which shows partially the external appearance structure of the escalator using the step of FIG.
