  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  With reference to FIG. 1, the example of a raising / lowering rope safety fence is demonstrated as a representative example of the raising / lowering apparatus which concerns on this invention. The elevating rope safety fence 10 is configured, for example, such that a plurality of support columns are installed at intervals along the platform edge 11a of the station platform 11, and the ropes are supported using these support columns. The rope is a regulation means for safely protecting passengers etc. who use the train at the station platform 11 from the train entering the station platform 11. In the illustrated example, the rope is configured by, for example, three ropes 12 with an interval in the vertical relationship. The length of the rope 12 is set to a length that substantially matches the length of the train that enters the station platform 11, and is installed along the platform edge 11 a of the station platform 11. The rope 12 is stretched between struts located at both ends in a tensioned state, and is arranged so that each of a plurality of intermediate struts is inserted through a portion such as a vertical slit formed therein. Has been. Elevating devices for raising and lowering the rope 12 are built in the pillars positioned at both ends, for example, the pillars 13 in FIG. The lifting / lowering operation (A) of the rope 12 by the lifting device is controlled by a control device (not shown), and the lifting / lowering motion of the rope 12 is linked to the operation of the train. That is, when the train enters or exits the station platform 11, the rope 12 moves to a lowered position to avoid the danger of the passenger 14 and functions as a safety fence. When the passenger 14 gets on and off the train The rope 12 moves to the raised position and opens the front space of the vehicle door.

  In the raising / lowering operation of the rope 12, when the rope 12 descends or when the rope 12 rises, there is a possibility that a part of the human body of the passenger 14 may come into contact depending on the location or behavior of the passenger 14. In particular, the possibility of contact is higher for children who have unpredictable behavior, persons with visual or hearing impairments, or persons who are focused only on their specific actions and are indifferent to their surroundings. . When such a contact state occurs, there is no problem if the contact is slight with respect to the human body. However, when a high frictional force acts on the contact between the rope 12 and the human body, or when an action such as pressing or striking occurs, a high load force is applied to the human body of the passenger 14 due to the contact. There is a risk of damage to the human body. Therefore, in order to reduce the load force due to such contact and prevent damage (harm) to the human body, the rope 12 is provided with a structure for reducing the contact load force as follows.

  FIG. 2 shows a first embodiment of the contact load force reducing structure. In this example, a portion of the surface of the rope 12 is covered with a material having a low frictional force so that the frictional force is entirely or partially reduced. 2A is an external view, and FIG. 2B is a longitudinal sectional view. In FIG. 2A, the covering material 21 having a low frictional force with respect to the rope 12 is exaggerated. In practice, the covering material 21 is a very thin film-like material. The structure is shown in FIG. The rope 12 is made of a core material 12a made of a metal wire and a resin coating portion 12b covering the core material 12a, and further, a buffer material 21a having flexibility around the surface of the resin covered portion 12b of the rope 12. The surface of the buffer material 21a is further covered with a film 21b made of a low friction material. The coating material 21 having a low frictional force is composed of a flexible buffer material 21a and a coating film 21b made of a low frictional friction material. In this configuration, the rope 12 itself is an existing product, and a coating material 21 having a low frictional force is provided externally to the surface of the existing rope 12.

  According to the rope 12 having the above-described structure for reducing the contact load force, when the rope 12 is moved up and down, the frictional force on the surface of the rope 12 in contact with the human body is low when the rope 12 comes into contact with the human body. 12 moves along the contour of the human body due to the low frictional contact state, and can avoid biting into the human body. Further, even when the rope 12 comes into contact with the passenger's human body in a pressing or striking manner, the action can be reduced by the covering material 21 having a low frictional force, and it can be released along the contour of the human body.

  In the example of the first embodiment described above, the surface of the rope 12 that is the lifting member is coated with the low frictional force covering material 21, but the surface of the rope 12 itself is configured to be a low frictional force surface. You can also

  FIG. 3 shows a second embodiment of the contact load force reducing structure. In this example, a cover member 31 attached to the rope 12 so as to be rotatable with respect to the rope surface is provided. 3A shows an external view, and FIG. 3B shows a longitudinal sectional view. The cover member 31 is a ring-shaped member that surrounds the rope 12 and is rotatable with respect to the rope 12. The ring-shaped member has a hollow pipe shape such as a bamboo ring. The length can be set arbitrarily. The cover member 31 is made using a foam material, a resin material, or the like. The surface of the cover member 31 can be a surface having a normal frictional force, or a surface having a low frictional force as in the first embodiment. As shown in FIG. 3B, a gap (play) 32 is provided on the surface of the rope 12 composed of the core material 12a and the resin covered portion 12b to provide a pipe-shaped foam material 31a. The surface is covered with a film 31b made of a material having a normal friction force or a low friction force. The cover member 31 is made of a pipe-shaped foam material 31a and a film 31b.

  According to the rope 12 having the above-described structure for reducing the contact load force, when the rope 12 moves up and down, the surface of the rotatable cover member 31 basically comes into contact with the human body when contacting the human body of the passenger 14. Therefore, the rope 12 itself moves while contacting the contour of the human body due to the rotation of the cover member 31, and does not contact the human body, thereby preventing the rope 12 from biting into the human body. Can do. The rotation action of the cover member 31 can prevent the rope 12 from giving a damaging load force to the human body. In addition, even when the rope 12 comes into contact with the passenger's human body in a pressing or striking manner, it is possible to create a state of escape by the rotating action of the cover member 31, reduce the action, and escape along the contour of the human body. It becomes.

  FIG. 4 shows a third embodiment of the contact load force reducing structure. In this example, a plurality of rotating members 31 attached to the rope 12 so as to be rotatable with respect to the rope surface are provided. The plurality of rotating members 41 are attached to the rope 12 with an equal fixed interval, for example. The structure of the longitudinal section of the rotating member 41 is substantially the same as the structure of the cover member 31 described above. Also with the rope 12 having this contact load force reducing structure, the contact load force can be reduced as in the case of the second embodiment. That is, when the rope 12 performs the lifting and lowering operation, when the surface of the plurality of rotatable rotating members 41 comes into contact with the human body when contacting the human body of the passenger 14, the rope 12 itself rotates the contacting rotating member 41. Therefore, it is possible to prevent the occurrence of a state in which the rope 12 bites into the human body while moving along the contour of the human body. In this way, it is possible to prevent the rope 12 from applying a damaging load force to the human body by the rotating action of the rotating member 41.

  FIG. 5 shows an elevating rope safety fence provided with a contact load force reducing structure according to the third embodiment. A plurality of rotating members 41 are attached to each of the three ropes 12 at appropriate intervals. Since other configurations are the same as those shown in FIG. 1, the same reference numerals are given to the same elements, and descriptions thereof are omitted. Also with this configuration, the rotating member 41 can prevent the rope 12 from harming the human body of the passenger 14.

  FIG. 6 shows a fourth embodiment of the contact load force reducing structure. In this example, a plurality of rotating members 51 attached to the rope 12 so as to be rotatable with respect to the rope surface, each having a plurality of rotating members 51 each having a spindle shape as a whole. . The plurality of rotating members 51 are attached to the rope 12 with an equal fixed interval, for example. The structure of the vertical section of the rotating member 51 is substantially the same as the structure of the rotating member 51 described above. Also with the rope 12 having this contact load force reducing structure, the contact load force can be reduced as in the case of the second embodiment. That is, when the rope 12 moves up and down, when the surface of the plurality of rotatable rotating members 51 comes into contact with the human body when contacting the human body of the passenger 14, the rope 12 itself is rotated by the rotating member 51 in contact with the human body. Therefore, it is possible to prevent the occurrence of a state in which the rope 12 bites into the human body while moving along the contour of the human body. Thus, the rotating action of the rotating member 51 can prevent the rope 12 from giving a damaging load to the human body.

The elevating device according to the present invention can be modified as follows.
In each of the above embodiments, the contact load force reducing structure is provided on the rope 12 of the liftable rope safety fence. However, a home fence configured to lift and lower a bar or rod other than the rope as a lifting member, for example. A contact load force reducing structure can be applied to the lifting member.
Further, for example, in a crossing device other than the home fence, a contact load force reducing structure can be provided on a lifting bar or a blocking rope.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented, and the numerical values and the compositions (materials) of the respective components Is just an example. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
