Description

  The present invention relates to a passenger conveyor such as an escalator and a moving sidewalk, and a guide shoe thereof.

  The passenger conveyor is attached to the frame, a frame installed in the building structure, a boarding floor provided at both ends of the frame in the longitudinal direction, a step connected endlessly and circulated between the boarding floor and the boarding floor. It is mainly composed of a guide rail that guides a step along a predetermined movement path, and a balustrade having a skirt guard that is also attached to the frame and arranged along the direction of movement of the step. The steps rotate a step board (also called cleats) on which passengers ride, risers that form the steps of each step, and rollers that run on the guide rails and are located near the side parts of these steps and the risers. A bracket that can be supported (in the case of an escalator, it is particularly called a triangular bracket) and a guide shoe attached to the bracket. The guide shoe is slidably contacted with the surface of the skirt guard, restricts the movement of the step in the left-right direction, and prevents foreign matter from being caught in a gap formed between the skirt guard and the step. On the other hand, the step on the moving sidewalk does not have a riser, and is configured with cleats, brackets, rollers, and guide shoes.

  By the way, as the steps of the passenger conveyor, with aluminum die casting or the like, the cleat and the bracket (including the riser for the escalator step) are integrally formed, and these members are separately manufactured with stainless steel or the like, Conventionally, it is known to be integrally assembled using a coupling member such as a bolt (for example, see Patent Document 1).

  FIG. 12 shows a step for an escalator manufactured by aluminum die casting, and shows a step 2 and a skirt guard 5. Further, the cleat 6, the riser 7, the triangular bracket 8, the front roller 11, the front shaft 10 to which the front roller 11 is attached, the rear roller 13, the rear shaft 12 to which the rear roller 13 is attached, and the guide shoe 14 are shown. As is apparent from this figure, a boss 8A for attaching the guide shoe 14 to the outer surface of the triangular bracket 8 is integrally formed on the escalator step 2 manufactured by aluminum die casting. For example, a bolt or the like is attached to the tip of the boss 8A.

  On the other hand, for the step 2 manufactured by assembling individual parts made of stainless steel or the like, it is costly to integrally form a boss 8A for attaching the guide shoe 14 to the outer surface of the triangular bracket 8. Is impossible. Therefore, as a means for attaching the guide shoe 14 to this type of step 2, a boss 8A manufactured as a separate member from the triangular bracket 8 or an alternative guide shoe attachment portion is attached to the outer surface of the triangular bracket 8 by post-processing. However, in this case as well, material costs and processing costs are significantly higher than steps manufactured by aluminum die casting.

  On the other hand, the same applicant as the present application has provided a reinforcing plate for connecting the step board on which the passenger rides and the bracket to make it easy, cheap and reliable to attach the guide shoe to the step. The plate has a notch for positioning the guide shoe formed at the end in the width direction of the step, and a connecting hole for connecting to a guide shoe formed at an inner portion of the notch for positioning. Includes a plate-like sliding contact portion whose one surface is a sliding contact surface with the skirt guard, and first and second ribs formed in parallel to each other surface of the sliding contact portion with a required gap therebetween. And a fitting protrusion formed between the first and second ribs and a connecting portion formed in parallel with the first and second ribs, and the first and second ribs. 2 ribs are in contact with the front and back surfaces of the reinforcing plate, and the mating protrusion is used as the reinforcing plate. With fits made a notch for positioning, configuration which is adapted to connect to the reinforcement plate connecting portion by utilizing Created coupling hole in the reinforcing plate it has been proposed as prior art (Patent Document 2).

JP 2004-161427 A Japanese Patent Application No. 2011-142990

  However, in the passenger conveyor proposed as the prior art, since the fitting protrusion that fits into the positioning notch formed in the reinforcing plate has a snap coupling structure with the claws, the claws are not picked up when the two are fitted. However, it was necessary to carry out while maintaining a state in which the outer diameter was reduced by applying a force so as to close to the center side. For this reason, the nail | claw part broke by repeated use etc., and the workability | operativity was eventually bad. Although a configuration in which a bolt is used instead of the claw portion is shown, it is troublesome to attach and detach the bolt, and as a result, workability cannot be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The passenger conveyor according to the present embodiment is bridged between a boarding / exiting floor 1 installed on the floor surface of each floor of the building as shown in FIG. 1, and the floor surface of the lower floor and the floor of the upper floor. A frame (not shown) that supports the entire escalator, a plurality of steps 2 that are connected endlessly and circulate between the lower floor boarding / exiting floor 1 and the upper floor boarding / exiting floor 1, and the moving direction of the step 2 A balustrade 3 arranged and attached to the frame described above, a moving handrail 4 arranged along the outer periphery of the balustrade 3 and circulating in the same direction as the step 2, and a skirt provided at the lower part of the balustrade 3 and attached to the frame described above A guard 5 is provided.

  As shown in FIGS. 2 and 3, the step 2 is arranged near the side of the cleat (step board) 6 on which the passenger rides, the riser 7 that forms the stepped portion of each step 2, and the side of the cleat 6 and the riser 7. The triangular bracket 8, the reinforcing plate 9 that connects the cleat 6 and the triangular bracket 8, the front roller 11 that is rotatably supported by the triangular bracket 8 through the front shaft 10, and the triangular bracket 8 through the rear shaft 12. The rear roller 13 is rotatably supported, and the guide shoe 14 is attached to the end of the reinforcing plate 9 and arranged on the outer surface side of the triangular bracket 8. The cleat 6 and the riser 7 are made of stainless steel, and the triangular bracket 8 and the reinforcing plate 9 are made of a thin steel plate. After each of these members is manufactured as an independent separate body, the cleat 6 and the riser 7, the cleat 6 and the reinforcing plate 9, and the reinforcing plate 9 and the triangular bracket 8 are integrally assembled with a coupling member such as a bolt. .

  As shown in FIG. 3, a guide rail 16 that guides the front roller 11 of the step 2 is provided on a frame 15 that spans between the floor surface of the lower floor and the floor surface of the upper floor and supports the entire escalator. A guide rail 17 for guiding the rear roller 13 of the step 2 is attached. The balustrade 3 is located outside the guide rail 16, and the skirt guard 5 is located inside the guide rail 16. A guide shoe 14, which will be described in detail later, is detachably held on the reinforcing plate 9 of the step 2, and a surface on the skirt guard 5 side of the guide shoe 14 is in sliding contact with the skirt guard 5.

  The reinforcing plate 9 is formed in a required shape capable of connecting the cleat 6 and the triangular bracket 8 as shown in FIGS. 2 and 4, and at the end in the width direction (skirt guard 5 side w), A positioning part 18 such as a notch is formed in order to restrict the mounting position of the guide shoe 14. The positioning portion 18 has a semicircular shape or a substantially square shape with rounded corners in order to facilitate processing and suppress stress concentration. In addition, two through holes 19A and 19B for holding the guide shoe 14 are formed side by side on the inner side (on the side of the skirt guard 5) from the position where the positioning portion 18 is formed. The guide shoe 14 is detachably held by using the positioning portion 18 and the through holes 19A and 19B.

  The guide shoe 14 is shown in FIG. 4, FIG. 5 which is a perspective view seen from the direction of arrow A in FIG. 4, FIG. 6 which is a perspective view seen from the direction of arrow B in FIG. As shown, it has a base portion 21 that has a sliding contact portion 20 and is formed in a substantially disk shape, and is fitted to the positioning portion 18 formed on the reinforcing plate 9 on the back surface side of the base portion 21. A mating portion 22 and a block-like facing member 23 that is positioned so as to sandwich the reinforcing plate 9 when the fitting portion 22 is fitted to the positioning portion 18 and that extends longer in the axial direction than the fitting portion 22; 24, and support members 25A and 25B that are integrally formed on the outer side of the facing member 24 and that are formed on the same plane as the facing member 24 on the side facing the facing member 23.

  The support members 25A and 25B are formed to extend longer in the axial direction than the facing member 24, and a slit 26 is formed between the facing member 24 and the supporting members 25A and 25B. The slit 26 provides a spring action or flexibility to the free ends of the pair of support members 25A and 25B.

  Further, on the free end side of the pair of support members 25A and 25B, projecting members 27A and 27B extending in the direction to be inserted into and withdrawn into the through holes 19A and 19B formed in the reinforcing plate 9 by the above-described spring action or flexibility, respectively, are integrated. Is formed. The portions of the projecting members 27A and 27B that are to be positioned in the through holes 19A and 19B have a straight columnar shape, a cylindrical shape, or other shapes, and the outer diameter thereof is larger than the diameter of the through holes 19A and 19B. Slightly smaller. Here, the projecting members 27 </ b> A and 27 </ b> B have a straight columnar shape from the coupling base portion to the distal end portion to the support members 25 </ b> A and 25 </ b> B, and the axial length thereof is slightly longer than the thickness of the reinforcing plate 9.

  The free ends of the support members 25A and 25B are made easy to insert the protruding members 28A and 28B into the through holes 19A and 19B by the spring action or flexibility of the slit 26, and conversely to pull them out. However, the deformation of the support members 25A and 25B on the free end side is realized not only by the slit 26 but also by forming the support members 25A and 25B extending from the base 21 and having an increased axial length separately from the facing member 24. be able to. In any case, the projecting members 27A and 27B can be inserted into the through holes 19A and 19B by the deformation of the free ends of the support members 25A and 25B, or can be pulled out, and the projecting members 27A and 27B. The axial length of is also set in consideration of the same point.

  Further, as shown in FIG. 5, the sliding contact portion 20 of the base portion 21 is formed with a chamfered portion 29 having a chamfered outer peripheral portion, and thereafter, a linear or other shape wear detecting groove 28 is formed. . As shown in FIG. 3, the slidable contact portion 20 is a slidable contact surface that is slidably contacted with the skirt guard 5, and when worn due to the slidable contact with the skirt guard 5, Since the degree of wear can be easily determined by the presence or absence, it is possible to easily know the replacement time of the guide shoe 14 and to improve the ease of maintenance of the passenger conveyor.

  Further, as shown in FIGS. 5 and 7, a chamfered portion 29 is provided at a corner portion of the outer peripheral surface of the sliding contact portion 20. In this way, the sliding contact portion 20 of the guide shoe 14 can easily get over the joint of the skirt guard 5, etc., so that the external force applied to the guide shoe 14 can be alleviated, and the generation of abnormal noise can be prevented. Durability can be increased. Moreover, the determination accuracy of the replacement time due to the change of the wear detection groove 28 described above can be further enhanced.

  Since the positioning portion 18 formed on the reinforcing plate 9 has a substantially quadrangular shape, the fitting portion 22 of the guide shoe 14 attached to the reinforcing plate 9 has a similar square shape. However, the positioning portion 18 has a semicircular shape or a rounded corner portion. In the case of forming a quadrangular shape, the fitting portion 22 is also formed in a semicircular shape or a quadrangular shape with rounded corners. With this configuration, even if an external force is applied from the sliding contact portion 20 side of the guide shoe 14, it is received by the positioning portion 18. For this reason, as shown in FIG. 8, when the protruding members 27A and 27B of the guide shoe 14 are inserted into the through holes 19A and 19B of the reinforcing plate 9, they are located between the inner wall surfaces forming the through holes 19A and 19B. Has a slight gap and maintains a substantially non-contact state.

  Such a guide shoe 14 is integrally formed of a material having low elasticity and appropriate elasticity such as polyacetal resin or polytetrafluoroethylene resin.

  Next, a method for attaching the guide shoe 14 to the reinforcing plate 9 will be described. First, the reinforcing plate 9 is positioned between the opposing members 23 and 24 of the guide shoe 14, and the fitting portion 22 is fitted into the positioning portion 18 of the reinforcing plate 9 while the guide shoe 14 is inserted. At this time, for example, the protruding members 27A and 27B of the supporting members 25A and 25B are deformed in a direction away from the reinforcing plate 9 so that the protruding members 27A and 27B formed on the supporting members 25A and 25B do not hinder the insertion of the guide shoe 14. Good to do.

  When the insertion of the guide shoe 14 is completed, the projecting members 27A and 27B are in positions corresponding to the through holes 19A and 19B formed in the reinforcing plate 9, and project as shown in FIG. 9 which is a front view and FIG. The members 27A and 27B are inserted into the through holes 19A and 19B. If the positional relationship between the protruding members 27A and 27B and the through holes 19A and 19B is as shown in the figure, it can be seen that the fitting portion 22 is correctly fitted to the positioning portion 18, and the protruding members 27A and 27B are impossible. No deformation is added.

  On the contrary, in this operation, when the guide shoe 14 is inserted while taking the target so that the protruding members 27A and 27B are inserted into the through holes 19A and 19B as shown in FIG. 8, the protruding members 27A and 27B In the state of being inserted into the through holes 19A and 19B, it can be seen that the fitting portion 22 is correctly fitted to the positioning portion 18.

  8 and 9, the inner wall surface by the through holes 19A and 19B formed in the reinforcing plate 9 and the outer peripheral surface of the projecting members 27A and 27B are not in contact with each other. is there. On the other hand, since the sliding contact portion 20 of the guide shoe 14 attached to the reinforcing plate 9 is slidably contacted with the skirt guard 5, the step 2 is accurately adjusted in the traveling direction with reference to the skirt guard 5 having a high accuracy of the fixed position. I can guide you well. At this time, the guide shoe 14 having the slidable contact portion 20 slidably contacted with the skirt guard 5 receives a force by contact with the skirt guard 5, but as described above, the fitting portion 22 is engaged with the positioning portion 18 of the reinforcing plate 9. The positions of the projecting members 27A and 27B do not change, and the inner wall surfaces of the through holes 19A and 19B and the outer peripheral surfaces of the projecting members 27A and 27B maintain a non-contact state. To do.

  However, when an undesired force is applied in the direction in which the guide shoe 14 is removed from the reinforcing plate 9, the outer peripheral surfaces of the projecting members 27A and 27B come into contact with the inner wall surfaces of the through holes 19A and 19B when trying to move slightly. Therefore, the movement is prevented and the guide shoe 14 can be prevented from falling off the reinforcing plate 9.

  Since the relationship between the through holes 19A and 19B formed in the reinforcing plate 9 and the projecting members 27A and 27B is determined in this way, the inner wall surface by the through holes 19A and 19B and the outer periphery of the projecting members 27A and 27B are determined in a steady state. Since the non-contact state is maintained with respect to the surface, the work of attaching the guide shoe 14 and the work of removing the guide shoe 14 can be easily performed.

  According to such a passenger conveyor, the mounting accuracy of the guide shoe 14 is improved by the engagement of the positioning portion 18 of the reinforcing plate 9 and the fitting portion 23 of the guide shoe 14, and the step 2 is accurately guided by the skirt guard 5. Therefore, the durability and reliability of the passenger conveyor can be improved. In the prior art, the projecting members 27A and 27B have a snap coupling structure with claws, but the outer peripheral surface of the snap coupling structure portion inserted into the through holes 19A and 19B is pressed against the inner wall surface of the through holes 19A and 19B. Therefore, when removing it, it is necessary to release the pressure contact by snap connection or remove the bolt, and the nails broke during the work and it was troublesome work, but in the steady state it penetrated Since the inner wall surface by the holes 19A and 19B and the outer peripheral surfaces of the projecting members 27A and 27B are kept in a non-contact state, the work of attaching the guide shoe 14 and the work of removing the guide shoe 14 can be easily performed.

  Further, since the wear detecting groove 28 is formed in the slidable contact portion 20, even if the slidable contact portion 20 is worn by sliding contact with the skirt guard 5 when the step 2 is moved, the wear detecting groove 28 is known from the situation and changes of the wear detecting groove 28. It is possible to easily determine the replacement time.

  Further, since the chamfered portion 29 is formed on the outer peripheral portion of the sliding contact portion 20, the sliding contact portion 20 of the guide shoe 14 can easily get over the joint of the skirt guard 5, etc., so that the external force applied to the guide shoe 14 can be alleviated and different. The generation of sound can be prevented and the durability of the guide shoe 14 can be enhanced.

  The through holes 19A and 19B are circular, and the projecting members 27A and 27B provided on the guide shoe 14 have an outer diameter smaller than the diameter of the through holes 19A and 19B and are columnar or cylindrical. The members 27A and 27B have a very simple structure, and it is not necessary to repeat the deformation of the claw portion when inserted into the through holes 19A and 19B formed in the reinforcing plate 9 as in the prior art, and the work can be performed without breaking. It becomes even easier. In addition, in a steady state other than when acting as a retainer, an excessive force does not act on the projecting members 27A and 27B due to a difference in diameter, so that the projecting members 27A and 27B can be easily inserted and removed, that is, the guide shoe 14 can be easily attached and detached. Can be.

  Although the above-described embodiment of the present invention has been described as a passenger conveyor, the present invention can also be handled by a single guide shoe. According to such a guide shoe 14, when the guide shoe 14 is attached to the skirt guard 5 side of the step 2, in a steady state due to the engagement between the positioning portion 18 of the reinforcing plate 9 and the fitting portion 22 of the guide shoe 14. The inner wall surface by the through holes 19A and 19B and the outer peripheral surface of the projecting members 27A and 27B can be kept in a non-contact state, and the insertion or withdrawal of the projecting members 27A and 27B of the guide shoe 14 becomes easy. 14 can be easily attached and detached. Further, in the state of being attached to the passenger conveyor, the attachment accuracy of the guide shoe 14 can be increased, and the steps can be accurately guided by the skirt guard 5.

  In addition, the other effects of the guide shoe 14 can provide substantially the same effect as that of the passenger conveyor.

  In the above-described embodiment, the escalator has been described as an example, but the present invention can be applied to a passenger conveyor including a moving sidewalk. When applied to a moving sidewalk, as shown in FIG. 11, as the step 2, a step that does not have the riser 7 of FIG. 2 and includes a square bracket 30 instead of the triangular bracket 8 is used. Since others are the same as the steps provided in the escalator, the corresponding parts are denoted by the same reference numerals and description thereof is omitted. FIG. 11 shows the front roller 11 and the rear roller 13, but any one of the rollers may be omitted.
