Description

  The present invention relates to passenger conveyors such as escalators and electric roads having a plurality of treads connected endlessly, and more particularly to a passenger conveyor having a tread board devised.

  In general, a gap is secured between the skirt guard and the tread board that extends vertically in the lower part of the balustrade, so that the clothes are not drawn into the gap so as to close the gap. A passenger conveyor in which a blocking member protrudes from the tread plate side and is brought into contact with the skirt guard has been already proposed as disclosed in, for example, Patent Document 1.

Japanese Utility Model Publication No. 7-4475

  By the way, the clearance between the tread board and the skirt guard is defined as “5 mm or less” by “Ministry of Construction Notification No. 1417 in 2000”. This specified gap is a gap on one side in the width direction of the tread. Therefore, when the tread is meandering and one side in the width direction contacts the skirt guard, the gap on the other side in the width direction of the tread is 10 mm. It becomes easy to get involved.

  Further, there are problems that the tread board makes contact with the skirt guard by meandering to generate a contact sound and scrapes off the sliding material applied to the surface of the skirt guard.

  With respect to these problems, according to the configuration disclosed in the above-mentioned Patent Document 1, the gap between the tread board and the skirt guard can be reduced to prevent the clothing from being caught, but the contact sound caused by the contact with the skirt guard due to the meandering of the tread board The problem that cannot be prevented remains. That is, in Patent Document 1, when a brush is used as a blocking member (FIG. 2 of Patent Document 1), the wire that is a component of the brush is crushed in contact with the skirt guard by meandering of the tread, and the wire is In the case where an elastic member made of rubber or the like is used as the blocking member (FIG. 3 of Patent Document 1), the friction member rubber is connected to the skirt guard. Contact will generate sliding noise.

  An object of the present invention is to provide a passenger conveyor capable of suppressing meandering of the tread board as well as preventing clothes from being caught in the gap between the tread board and the skirt guard.

  In order to achieve the above object, the present invention provides a low-friction meandering restricting means that protrudes toward the skirt guard with a projecting dimension smaller than the dimension of the gap between the tread board and the skirt guard, at a portion facing the skirt guard of the tread board. It was provided.

  With this configuration, during normal movement of the tread, the meandering restricting means moves without securing the normal gap between the tread and the skirt guard without contacting the skirt guard. Therefore, the clothes are not easily caught in the gap, and even if they are caught, the tread board and the skirt guard do not come into contact with each other due to the meandering suppression means. Therefore, the clothes can be easily pulled out by pulling the clothes. In addition, when the treadle moves meandering, the low friction meandering limiting means provided on the side of the treadle comes into contact with the skirt guard to suppress meandering so that the gap between the treadle and the skirt guard is not further narrowed. Can do. Therefore, the gap between the meandering restricting means of the tread board and the skirt guard on the side opposite to the side that contacts the skirt guard is not so large, and it is possible to prevent clothes from being caught easily. It can be easily pulled out by pulling clothes. Further, when the meandering of the tread is suppressed, the meandering restricting means provided on the treadle side comes into contact with the skirt guard, but the meandering restricting means has low friction, so that the sliding noise with the skirt guard is reduced. Generation | occurrence | production can be prevented and the scraping of the sliding material on the surface of a skirt guard can be prevented.

  As described above, according to the present invention, it is possible to obtain a passenger conveyor capable of suppressing meandering of the tread board as well as preventing clothes from being caught in the gap between the tread board and the skirt guard.

  Hereinafter, an embodiment of a passenger conveyor according to the present invention will be described based on the escalator shown in FIGS.

  The escalator 1 is guided to a step 2 connected endlessly and circulated, a balustrade 3 erected on a fixing member such as a frame positioned on both sides of the step 2 in the width direction, and a periphery of the balustrade 3 And a skirt guard 5 extending in the vertical direction to partition the lower part of the balustrade 3 from the step 2.

  The step 2 includes a step plate 2A that is maintained in a horizontal state when a passenger is boarding, and a riser 2B that extends downward from the lower floor side end of the step plate 2A. The width of the step plate 2A and the riser 2B A predetermined gap m that is a predetermined value of 5 mm or less with respect to the skirt guard 5 is secured at both ends in the direction.

  Further, voids 2a are formed at a plurality of locations on the side of the step 2, and a roller 2c, which is a low friction meandering limiting means and a rotating body according to the present invention, is rotated by the support shaft 2b in the voids 2a. It is supported freely. These rollers 2c protrude toward the skirt guard 5 with a protruding dimension m1 that is equal to or less than the predetermined gap m, and a gap m2 is secured between the roller 2c and the skirt guard 5. The roller 2c is pivotally supported so that it can rotate along the moving direction so that it can be easily rotated when it contacts the skirt guard 5 while the step 2 is moving.

  In the above configuration, when the escalator 1 is in operation, if the step 2 meanders and moves in a direction to narrow the specified gap m, the roller 2c closes the gap m2 with the skirt guard 5 and contacts the skirt guard 5. At this time, the specified gap m between the step 2 and the skirt guard 5 is a gap m1 (m−m2), and the gap (not shown) between the step 2 and the skirt guard on the opposite side in the width direction is m + m2. Thus, the gap is not twice as large as the prescribed gap m.

  Therefore, if the step 2 is meandering and clothing or the like is caught in the narrow gap m1 on the side approaching the skirt guard 5, the gap does not become zero and the gap m1 is secured. When you feel a sense of incongruity, you can easily pull it out and pull it out. On the other hand, clothing or the like is easily caught on the side where the gap with the skirt guard 5 is enlarged, but the gap is not closed by the meandering of the step 2 and a gap is secured between the roller 2c and the skirt guard 5. Therefore, when clothes etc. are caught, clothes etc. can be pulled out easily similarly.

  Further, since the roller 2c for suppressing meandering of the step 2 is rotatably supported, it can be easily rotated even if it contacts the skirt guard 5, so that a large sliding noise is generated with respect to the skirt guard 5. There is nothing. When the roller 2c is a metal roller, a certain amount of contact noise with the skirt guard 5 is generated. However, if this is a concern, the outer peripheral side of the roller 2c or the roller itself should be made of rubber. Thus, the contact noise can be further reduced.

  By the way, the escalator 1 moves horizontally in the getting-on / off section, and the step 2 moves obliquely along the inclination in the inclined section. Therefore, when the support shaft 2b supporting the roller 2c is fixed, the escalator 1 is horizontal. And the support shaft 2b may be fixed so that the rotation direction is in the middle of the inclination.

  However, even if the support shaft 2b that supports the roller 2c is fixed so that the rotation direction is intermediate between the horizontal and the inclination, the traveling direction of the step 2 does not completely coincide with the rotation direction of the roller 2c. For this reason, when the roller 2c comes into contact with the skirt guard 5, there is a possibility that sliding occurs between them, generating sliding noise or scraping off the sliding material applied to the surface of the skirt guard 5 by sliding. I can't deny it.

  In such a case, instead of the roller 2c, a sphere is rotatably embedded in the step 2 side so that the sphere can freely rotate with respect to a change in the direction of travel of the step 2. There is no sliding between them, and no sliding noise is generated and the sliding material of the skirt guard 5 is not scraped off.

  Further, although the low friction sliding member protrudes from the step 2 side toward the skirt guard 5 instead of the roller 2c, sliding occurs between the skirt guard 5 and the low friction sliding member. Thus, the generation of sliding noise can be suppressed, and the sliding material of the skirt guard 5 can be prevented from being scraped off.

  In addition, when the roller 2c is used, for example, the roller 2c is attached to the step 2 via a displacement follower that is a mechanism such as a free caster that can change the direction of the wheel according to the direction of the force. do it. With this configuration, when the roller 2c comes into contact with the skirt guard 5, the roller 2c changes its direction in a direction coinciding with the moving direction of the step 2 at that time, so that the roller 2c slides. It is possible to rotate smoothly without any sliding noise.

  By the way, although embodiment described above demonstrated the escalator as an example as a passenger conveyor, this invention is applicable also to the electrically-driven road which connected the several step board in endless form.
