JP 2009-51602 A

  The demarcation used in the steps of the escalator device as described above is made of synthetic resin such as polycarbonate, and the load and impact are repeatedly applied by passengers and luggage for a long time. Therefore, it is necessary to exchange demarcation. In particular, the rear end side demarcation located on the rear end side of the tread board is less likely to break or wear than the front end side demarcation, left end side demarcation, or right end side demarcation that faces the riser board of the previous step. And there is a high need for replacement.

  In this replacement operation, first, the tread (including the tread reinforcement provided on the back of the tread) is removed from the bracket, and then the rear end demarcation and front end demarcation are fixed to the tread reinforcement. Loosen the screws, and then remove the rear end demarcation and front end demarcation from the tread (strictly, the tread plate reinforcement plate), and then remove the new rear end demarcation and front end demarcation from the tread (strictly, the tread plate reinforcement plate). ) And fixed again with fixing screws.

  By the way, as shown in FIG. 9, the conventional new rear end side demarcation 16A is connected to the ridge portion 16A-1 connected to the ridge portion of the tread 14 on the upper surface side, and this ridge portion 16A-1. The main body portion 16A-2 having a hole through which the fixing screw 20 is inserted, and the end portion of the tread plate 14 inserted and moved between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 as shown in FIG. 14A and an engaging portion 16A-3 that engages between the end portion 18A of the tread plate reinforcing plate 18. The “end portion” here means not only the tip end but also the “end portion” including the vicinity thereof. A rib portion 16A-4 that increases strength is formed between the main body portion 16A-2 and the engaging portion 16A-3.

  Then, this new rear end side demarcation 16A inserts and moves the engaging portion 16A-3 into the gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 as shown in FIG. The ridge portion of the tread plate 14 and the ridge portion 16A-1 of the rear end side demarcation 16A are fixed together with the fixing screw 20 after performing the aligning operation.

  However, the end portion 18A of the tread plate reinforcing plate 18 is bent or warped due to manufacturing errors or careless handling, and the gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 is narrowed. There is a case. For this reason, in the process of the above-described replacement operation, the lower end surface of the engaging portion 16A-3 collides with the end portion 18A of the tread plate reinforcing plate 18 and collides, and the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 There was a problem that the replacement work was delayed due to poor insertion and movement in the gap between the two.

  Similarly, as shown in FIG. 11, the new front end side demarcation 16D has a protrusion 16D-1 connected to the protrusion of the tread 14 on the upper surface side, and a main body 16D- having a hole through which the fixing screw 20 is inserted. 2, the engaging portion 16D-3 that is inserted, moved, and engaged between the end portions of the tread plate 14 and the tread plate reinforcing plate 18, and the main body portion 16D-2 and the engaging portion 16D-3 are connected to each other to be strong. It is comprised from the rib part 16D-4 which raises. Here, since the front end side demarcation 16D faces the riser plate 12 of the previous step, the front end side demarcation 16D is different from the rear end side demarcation 16A in that the front and rear sides of the protrusion 16D-1 are extended and extended. However, the basic shape is similar.

  Then, as shown in FIG. 12, the new front end demarcation 16D inserts and moves the engaging portion 16D-3 into the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18, The fixing screw 20 is used to fix the protruding portion of the tread plate 14 and the protruding portion 16D-1 of the front end side demarcation 16D.

  However, as described above, the end portion 18D of the tread plate reinforcing plate 18 is bent or warped due to manufacturing errors, careless handling, etc., and the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18 are between. The gap may be narrowed. For this reason, in the process of exchanging the front end side demarcation 16D, it is difficult to insert and move the engaging portion 16D-3 into the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18. There was a problem that its workability was slow.

  The object of the present invention is to replace the rear end side demarcation and the front end side demarcation between the end of the tread plate and the end of the tread plate reinforcing plate when exchanging the rear end demarcation and the front end demarcation. It is an object of the present invention to provide a passenger conveyor step and a passenger conveyor that can be smoothly inserted, moved and engaged in a gap so that the rear end demarcation and the front end demarcation can be easily replaced.

  A feature of the present invention is that an inclined portion that is inclined toward the lower end surface of the main body portion is formed in the engaging portion formed in the rear end side demarcation or the front end side demarcation, and the end portion of the tread plate is utilized by using the inclined portion. By pushing and widening the gap between the end of the treadle plate and the end of the treadle plate, the rear end side demarcation and the engaging part of the front end side demarcation can be smoothly inserted and moved to move the end of the tread plate and the end of the tread plate reinforcing plate It is in the place where it was made to engage between.

  According to the present invention, even if the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate is narrowed, the inclined portion formed at the engaging portion of the rear end side demarcation or the front end side demarcation is utilized. The engaging portion can be smoothly moved by widening the gap between the end portions of the tread plate and the tread plate reinforcing plate. As a result, the rear end side demarcation and the front end side demarcation can be easily replaced, and the replacement workability can be greatly improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments, and various modifications and application examples are included in the technical concept of the present invention. Is also included in the range. As described above, the passenger conveyor described below describes the escalator device, but the present invention is not limited to this escalator device, and is also applicable to an electric road or the like known as a moving sidewalk. Is something that can be done.

  Before describing an embodiment of the present invention, the configuration of steps of an escalator device that is one of passenger conveyors will be described with reference to FIGS.

  In FIG. 1, step 10 basically includes a bracket 50, and a kick-up plate 12 and a tread plate 14 fixed to the bracket 50 with bolts (not shown). The kick-up plate 12 is formed in a shape that hangs downward with an arc surface from the rear end side of the tread plate 14 placed horizontally. For the safety of passengers on the upper surface of the tread board 14, around the tread board 14 (rear end, left end, right end, front end) for the purpose of recognizing the range (size) of the four sides of the tread board The rear end side demarcation 16A (the riser plate 12 side), the left end side demarcation 16B, the right end side demarcation 16C, and the front step riser plate 12 colored in a highly discriminating color such as yellow Opposing front end side demarcation 16D is fixed. The rear end side demarcation 16A and the front end side demarcation 16D are divided into three parts. In the case of a moving sidewalk, there is no step between the adjacent step 10 and thus the kick-up plate 12 is unnecessary.

  As shown in FIG. 2, the tread 14 is provided with a tread reinforcing plate 18 fixed by a fixing method such as welding on its lower surface, and each demarcation 16A to 16D is provided on the tread 14 in this state. It is fixed. More specifically, each of the demarcations 16A to 16D is placed around the upper surface (four sides) of the tread plate 14 and fixed to screw holes (not shown) formed in the tread plate reinforcing plate 18 by the fixing screws 20. Is. Although only the rear end side demarcation 16A is shown as the fixing screw 20, the left end side demarcation 16B, the right end side demarcation 16C, and the front end side demarcation 16D are similarly fixed to the tread plate reinforcing plate 18 by the fixing screw 20. Is. In this way, the step 10 is completed by fixing the step plate 14 to which the demarcations 16A to 16D are integrally fixed to the bracket 50 to the step plate reinforcing plate 18 with bolts.

  In the step of the escalator apparatus, the embodiment of the present invention will be described in detail.

  FIG. 3 shows the configuration of the rear end demarcation 16A according to the first embodiment of the present invention. The same reference numerals as those of the conventional rear end demarcation 16A denote the same components or components having similar functions. Is shown.

  In FIG. 3, the rear end side demarcation 16 </ b> A has a ridge portion 16 </ b> A- 1 connected to the ridge portion of the tread 14 on the upper surface side, and a fixing screw 20 inserted so as to continue to the lower side of the ridge portion 16 </ b> A- 1. And a main body 16A-2 having a hole 22 to be provided. On the upper side of the main body portion 16A-2, a tread plate receiving portion 16A-5 that is in contact with the lower surface side (back side) of the end portion 14A of the tread plate 14 is formed so as to extend a predetermined length along the lower surface side of the tread plate 14. Yes.

  A plurality of rib portions 16A-4 rising from the main body portion 16A-2 are formed below the tread plate receiving portion 16A-5. The rib portions 16A-4 support the tread plate receiving portion 16A-5 so as to support the tread plate receiving portion 16A-5. It is formed integrally with 16A-5. The end surfaces of the tread board receiving portion 16A-5 and the rib portion 16A-4 are the same plane, so-called flush. A hole 22 through which the fixing screw 20 is inserted is formed at a portion where the rib portion 16A-4 and the main body portion 16A-2 intersect, thereby preventing a decrease in strength due to thinning caused by forming the hole 22. .

  The rib portion 16A-4 described above corresponds to the rib portion 16A-4 provided in the conventional rear end side demarcation 16A, but in the present embodiment, the conventional engaging portion 16A-3 is omitted. The rib portion 16A-4 functions as an engaging portion. Therefore, in the following, it is basically expressed as the engaging portion 16A-4, but in some cases, it is expressed as the rib portion 16A-4 for convenience of explanation.

  On the end surface of the engaging portion 16A-4, there is formed an inclined portion 16A-6 that is cut from the predetermined starting point A toward the lower end surface B of the main body portion 16A-2 with a predetermined angle. The portion where the inclined portion 16A-6 is provided is determined by the degree to which the gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 is narrowed. The narrower the gap, the more the inclined portion 16A-6 has. The starting point needs to be set so as to approach the upper side, that is, the tread board receiving portion 16A-5. In short, the inclined portion 16A-6 may be inclined so as to enter the gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18.

  Further, in the present embodiment, the inclined portion 16A-6 is continuously formed at the corner portion C on the engaging portion 16A-4 side of the lower end surface B of the main body portion 16A-2. If the corner portion C of the lower end surface B of the main body portion 16A-2 is not inclined, the rear end side demarcation 16A is inserted into the gap between the step plate 14 and the end portion 18A of the step plate reinforcing plate 18 and moved. This is because the corner portion C may interfere with the end portion 18A of the tread plate reinforcing plate 18 and the engagement work becomes difficult.

  Although the conventional engaging portion 16A-3 is omitted in this embodiment, rib portions 16A-4 functioning as engaging portions in FIG. 3 are formed on both end surfaces in the width direction of the main body portion 16A-2. Accordingly, all the rib portions 16A-4 can be connected in the same manner as the conventional engaging portion 16A-3, and the strength of this portion can be further increased. Of course, even in this case, it goes without saying that the inclined portion 16A-6 is formed by cutting off the conventional engaging portion 16A-3.

  Further, in the present embodiment, the tread receiving portion 16A-5 is formed over the width direction of the main body portion 16A-2, but is formed only on the rib portion 16A-4, and above the rib portion 16A-4. The tread surface receiving portion 16A-5 formed in the above may be moved along the lower surface side of the end portion 14A of the tread plate 14.

  FIG. 4 shows a state in which the rear end side demarcation 16A having the above-described configuration is incorporated in the tread plate 14. 4 shows a state in which the tread plate 14 is fixed to the bracket 50. Actually, the rear end demarcation 16A is fixed in advance to the tread plate 14 before fixing the tread plate 14 to the bracket 50. Is.

  As shown in FIG. 4, the tread plate 14 and the tread plate reinforcing plate 18 are firmly fixed by a fixing method such as welding, but the end portion 18A of the tread plate reinforcing plate 18 is bent due to a manufacturing error or careless handling. In some cases, the gap between the footboard 14 and the end 18A of the footboard reinforcing plate 18 is narrowed. Therefore, in the process of exchanging the rear end side demarcation 16A, the lower end surface of the engaging portion 16A-3 interferes with the end portion 18A of the tread plate reinforcing plate 18 in the conventional rear end side demarcation 16A shown in FIG. There was a problem that it was difficult to insert and move in the gap between the end portions of the tread plate 14 and the tread plate reinforcing plate 18 and the workability was significantly delayed.

  On the other hand, in this embodiment, the inclined portion 16A-6 is formed in the engaging portion 16A-4. Therefore, when the rear end side demarcation 16A is fixed to the tread plate 14, if the tread plate receiving portion 16A-5 of the rear end side demarcation 16A is moved along the lower surface side of the end portion 14A of the tread plate 14, a predetermined amount is obtained. When the distance is advanced, the inclined portion 16A-6 formed in the engaging portion 16A-4 and the end portion 18A of the tread plate reinforcing plate 18 come into contact with each other.

  When the rear end side demarcation 16A is further pushed in this state, the gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18 is pushed and expanded by the wedge action of the inclined portion 16A-6. Thus, the engaging portion 16A-4 can be smoothly inserted and moved, and the engaging portion 16A-4 is engaged in a gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcing plate 18. Will be. That is, the lower end surface B of the main body portion 16A-2, the engaging portion 16A-4, and the tread plate receiving portion 16A-5 are engaged by a gap between the end portion 14A of the tread plate 14 and the end portion 18A of the tread plate reinforcement plate 18. Will be held.

  When the end portion 14A of the tread plate 14 finally comes into contact with the protrusion 16A-1 of the rear end side demarcation 16A, the engagement operation is completed. In this state, the rear end side demarcation 16A is fixed to the tread plate reinforcing plate by the fixing screw 20. By fixing to 18, the replacement work of the rear end side demarcation 16A is completed. Step 10 is assembled by fixing the tread 14 after the replacement work to the base 24 fixed to the bracket 50 with a bolt (not shown). The base 24 may also have a function of reinforcing the kick-up plate 12.

  As described above, according to the present embodiment, an inclined portion that is inclined toward the lower end surface of the main body portion is formed in the engaging portion of the rear end side demarcation, and the end portion of the tread plate and the tread plate are utilized using this inclined portion. By widening the gap between the end portions of the reinforcing plate, the engaging portion can be smoothly inserted into and moved into the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate. .

  Therefore, even if the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate is narrowed, the engaging portion is made to reinforce the tread plate end portion and the tread plate using the inclined portion of the engaging portion of the rear end side demarcation. It is possible to smoothly insert and move in the gap between the end portions of the plate. As a result, the rear end demarcation can be easily replaced, and the workability can be greatly improved.

  Next, a modification of the first embodiment will be described with reference to FIG. The modification shown in FIG. 5 shows an example in which a curved inclined portion 16A-6 is employed instead of the linear inclined portion 16A-6.

  In FIG. 5, an inclined portion 16 </ b> A- 6 having a predetermined curvature curve is provided between the portion where the engaging portion 16 </ b> A- 4 and the tread board receiving portion 16 </ b> A- 5 intersect with the lower end surface B of the main body portion 16 </ b> A- 2. An engaging portion 16A-4 is provided. Of course, also in this modified example, the curved inclined portion 16A-6 is continuously formed in the corner portion C of the lower end surface B of the main body portion 16A-2.

  Since the operation and effects of the engaging portion of this modification are the same as those of the previous embodiment, further explanation is omitted, but in any case, the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate is narrowed. However, the engaging portion can be smoothly inserted and moved into the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate using the inclined portion of the engaging portion, and as a result, the rear end side The demarcation can be easily exchanged, and the workability can be greatly improved.

  FIG. 6 shows a configuration of a front end side demarcation 16D according to the second embodiment of the present invention. The same reference numerals as those of the conventional front end side demarcation 16D indicate the same components or components having similar functions. ing.

  In FIG. 6, the front end side demarcation 16 </ b> D has a protrusion 16 </ b> D- 1 extending on the upper surface side so as to face the protrusion of the tread 14 and the protrusion of the kick-up plate 12 of the previous step 10, and this protrusion A main body portion 16D-2 including a hole 22 through which the fixing screw 20 is inserted is provided below the strip portion 16D-1. On the upper side of the main body portion 16D-2, a tread plate receiving portion 16D-5 that is in contact with the lower surface side (back side) of the end portion 14A of the tread plate 14 is formed so as to extend a predetermined length along the lower surface side of the tread plate 14. Yes. Although the tread plate receiving portion 16A-5 of the rear end side demarcation described above extends toward the front side of the tread plate 14, the tread plate receiving portion 16D-5 of the front end side demarcation of this embodiment is the rear side of the tread plate 14. It extends towards.

  A rib portion 16D-4 rising from the main body 16D-2 is formed on the lower side of the tread plate receiving portion 16D-5. The rib portion 16D-4 and the tread plate receiving portion 16D-5 are supported so as to support the tread plate receiving portion 16D-5. It is integrally formed. The end faces of the tread board receiving portion 16D-5 and the rib portion 16D-4 are the same plane, so-called flush.

  The rib portion 16D-4 corresponds to the rib portion 16D-4 provided in the front end side demarcation 16D shown in FIG. 11, but in this embodiment, the engaging portion 16D-3 shown in FIG. Since it is omitted, the rib portion 16D-4 functions as an engaging portion. Therefore, in the following, it is basically expressed as the engaging portion 16D-4, but in some cases, it is expressed as the rib portion 16D-4 for convenience of explanation.

  On the end surface of the engaging portion 16D-4, an inclined portion 16D-6 is formed which is cut from the predetermined start point D toward the lower end surface B of the main body portion 16D-2 with a predetermined angle. The portion where the inclined portion 16D-6 is provided is determined by the degree to which the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18 is narrowed. The starting point needs to be set to be close to the upper side, that is, the tread board receiving portion 16D-5. The point is that the inclined portion 16D-6 may be inclined so as to enter the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18.

  Further, in this embodiment, similarly to the first embodiment, the inclined portion 16D-6 is continuously formed in the corner portion C of the lower end surface B of the main body portion 16D-2. If the corner portion C of the lower end surface B of the main body portion 16D-2 is not inclined, the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcement plate 18 shown in FIG. This is because the corner C may interfere with the end 18D of the tread plate reinforcing plate 18 when it is inserted and moved, making it difficult to perform the work.

  In this embodiment, the conventional engaging portion 16D-3 is omitted, but by forming rib portions 16D-4 functioning as engaging portions in FIG. 6 on both end surfaces of the main body portion 16D-2, All the rib portions 16D-4 can be connected in the same manner as the conventional engaging portion 16D-3, and the strength of this portion can be further increased. Of course, even in this case, it goes without saying that the inclined portion 16D-6 is formed by cutting off the conventional engaging portion 16D-3.

  FIG. 7 shows a state in which the front end side demarcation 16D having the above-described configuration is incorporated in the tread board. In this embodiment, the inclined portion 16D-6 is formed in the engaging portion 16D-4. Therefore, when the front end side demarcation 16D is fixed to the tread board 14, if the tread board receiving part 16D-5 of the front end side demarcation 16D is moved along the lower surface side of the end part 14A of the tread board 14, a predetermined distance is obtained. When advanced, the inclined portion 16D-6 formed in the engaging portion 16D-4 and the end portion 18D of the tread plate reinforcing plate 18 come into contact with each other.

  When the front end side demarcation 16D is further pushed in this state, the gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcing plate 18 is pushed and expanded by the wedge action of the inclined portion 16D-6. The engaging portion 16D-4 can be smoothly inserted and moved. The lower end surface B of the main body portion 16D-2, the engaging portion 16D-4, and the tread plate receiving portion 16D-5 are engaged by a gap between the end portion 14A of the tread plate 14 and the end portion 18D of the tread plate reinforcement plate 18. Will be held.

  When the end portion 14A of the tread plate 14 finally comes into contact with the protrusion 16D-1 of the front end side demarcation 16D, the engagement operation is completed, and in this state, the front end side demarcation 16D is attached to the tread plate reinforcing plate 18 by the fixing screw 20. The replacement work of the front end side demarcation 16D is completed by fixing. Step 10 is assembled by fixing the tread 14 after the replacement work to the base 45 fixed to the bracket with a bolt. The base 45 may also serve as a reinforcing plate (pre-reinforcement).

  As described above, according to the present embodiment, the engaging portion of the front end side demarcation is formed with the inclined portion that is inclined toward the lower end surface of the main body portion, and the end of the tread plate and the tread plate reinforcing plate is utilized using this inclined portion. By widening the gap between the portions, the engaging portion can be smoothly inserted and moved into the gap between the end portions of the tread plate and the tread plate reinforcing plate to engage with each other.

  Therefore, even if the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate is narrowed, the inclined portion of the engaging portion of the demarcation is used to move the engaging portion between the end portion of the tread plate and the tread plate reinforcing plate. As a result, the front end side demarcation can be easily replaced and the workability can be greatly improved.

  Next, a modification of the second embodiment will be described with reference to FIG. The modification shown in FIG. 8 shows an example in which a curved inclined portion 16D-6 is employed instead of the linear inclined portion 16D-6.

  In FIG. 8, between the starting point D of the engaging portion 16D-4 and the lower end surface B of the main body portion 16D-2, the engaging portion 16D-4 having an inclined portion 16D-6 having a predetermined curvature curve is provided. Is provided.

  Since the operation and effect of the engaging portion 16D-4 are the same as in the previous embodiment, further explanation is omitted, but in any case, the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate is narrowed. However, the engaging portion can be smoothly inserted and moved in the gap between the end portion of the tread plate and the end portion of the tread plate reinforcing plate by using the inclined portion of the engaging portion, and as a result, the front end side demarcation Can be easily replaced, and the workability can be greatly improved.
