  Embodiments of the present invention will be described below with reference to FIGS. In addition, the same code | symbol is attached | subjected to the part same as the conventional structural part, and the duplicate description is abbreviate | omitted.

  1 to 5 show a first embodiment of the present invention. A stopper member 20 is attached to a tail cord 7 housed in a housing duct 10. The stopper member 20 is formed in a flat plate shape from metal or synthetic resin.

  One or a plurality of stopper members 20 are attached to the tail cord 7 with a predetermined pitch. The tail cord 7 moves together with the car 2 and the portion facing the opening 11 of the storage duct 10 changes sequentially, but at least one stopper member 20 is attached to the portion of the section that always faces the opening 11. Yes.

The stopper member 20 is horizontally attached to the tail cord 7 that hangs vertically, and is in a relationship capable of facing the opening 11. The length of the stopper member 20, that is, the horizontal length L ₁ parallel to the opening surface of the opening 11 is larger than the horizontal width L ₂ of the opening 11.

  According to such a configuration, when the tail cord 7 is greatly swung in the storage duct 10 and the portion facing the opening 11 is about to jump out through the opening 11, the stopper member 20 is located on the inner side on both sides of the opening 11. The protrusion is suppressed by contacting the wall surface. Therefore, damage to the tail cord 7 due to the protrusion can be prevented.

  FIG. 6 shows a second embodiment. In this embodiment, a buffer material 21 made of an elastic body such as rubber is attached to the outer surface of the stopper member 20. This buffer material 21 is attached so that at least the stopper member 20 covers a portion that abuts against the inner wall surface of the storage duct 10 by the swinging motion thereof.

  According to such a configuration, when the stopper member 20 swings greatly in the storage duct 10 together with the tail cord 7, the stopper member 20 contacts the inner wall surface of the storage duct 10 through the buffer material 21. At this time, the shock caused by the contact is relieved by the cushioning material 21, and the inconvenience that the noise due to the shock is transmitted to the car or the living space of the building can be prevented.

  7 and 8 show a third embodiment. In this embodiment, a plurality of stopper members 20 are attached to the tail cord 7 with a certain pitch, and these stopper members 20 have, for example, a tape shape. They are sequentially rolled through a flexible connecting material 23 formed. Each stopper member 20 is connected by a connecting member 23 at one end side with the tail cord 7 as a boundary.

  The tail cord 7 is moved up and down in the storage duct 10 in a state of being suspended in the storage duct 10. At this time, if the tail cord 7 swings greatly, the belt-like tail cord 7 is twisted so as to twist. , Its durability may be reduced.

  However, in this embodiment, a plurality of stopper members 20 are attached to the tail cord 7 with a certain pitch, and the plurality of stopper members 20 are sequentially connected by a tape-like connecting material 23. Therefore, the twist of the tail cord 7 can be suppressed by the connecting member 23, and therefore, the durability of the tail cord 7 can be prevented from being lowered due to the twist.

  Further, when the stopper member 20 is detached from the tail cord 7 for some reason, the stopper member 20 is connected to the other stopper member 20 via the connecting member 23. Therefore, the stopper member detached from the tail cord 7 is used. 20 does not fall below the tail cord 7.

  In the embodiment shown in FIG. 7, the end portions on one end side of each stopper member 20 are connected by the connecting member 23, but when the end portions on the other end side of the stopper member 20 are connected, or The case where both ends are connected may be sufficient.

  9 and 10 show a fourth embodiment. In this embodiment, two tail cords 7a and 7b having a band shape are connected to the hitch 8 in parallel, and these two tail cords are connected. A plurality of stopper members 20 are attached to 7a and 7b with a certain pitch.

  The two tail cords 7a and 7b are in contact with each other at the connection portion to the hitch 8, but at the portion extending from the hitch 8, the belt surfaces are spaced apart from each other at a constant interval. It has been spread. The spacing distance is kept constant by the stopper member 20.

  That is, the tail cords 7a and 7b pass through the stopper members 20 with a certain interval therebetween, so that the interval is kept constant. One of the tail cords 7 a and 7 b is fixed to each stopper member 20, and the other is loosely inserted with respect to the stopper member 20.

  As for the tail cords 7a and 7b, the position of the U-shaped bent portion of the lower end of the tail cord 7a and 7b is successively changed according to the movement of the car. The stopper member 20 is fixed only to one tail cord 7a and is loosely engaged with the other tail cord 7b. The tail cords 7a and 7b are smoothly bent into a U shape.

  When two tail cords 7a and 7b are used, if the two tail cords 7a and 7b are joined, it becomes easy to twist during the movement. When 7a and 7b are in a state of being spaced apart from each other at a constant interval, the twisting thereof is suppressed, and the durability of the tail cords 7a and 7b can be prevented from being lowered. Then, the tail cords 7a and 7b can be separated at a constant interval by using the stopper member 20, and no other dedicated member is required, and the cost can be reduced accordingly.

  11 and 12 show a fifth embodiment. In this embodiment, one tail cord 7 is connected to the hitch 8, and a plurality of stopper members 20 have a constant pitch. Open and installed. A linear member 24 having a certain tension such as a wire and capable of elastic deformation is stretched between end portions of one end side of each stopper member 20. As shown in FIG. 11, two linear members 24 are attached to the end portions of the stopper members 20 in parallel via clips 25.

  The tail cord 7 has a lower end bent into a U-shape and is suspended in the storage duct 10. The linear body 24 is an end of each stopper member 20 facing inward of the U-shape. It is installed in between.

  The tail cord 7 suspended in a U-shape is in a state where the upper portion of the U-shape extends in parallel. When the tail cord 7 swings, the tail cords 7 facing each other in the parallel portion are mutually connected. There is a risk that the stopper members 20 attached to the parallel portions will cross each other and become entangled with each other.

  However, in this embodiment, since the linear member 24 such as a wire is stretched between the end portions of the stopper member 20, the linear member 24 prevents interference such that the stopper members 20 cross each other, and therefore The entanglement can be avoided, the tail cord 7 can be moved smoothly, and the occurrence of vibration and noise due to the entanglement can be prevented.

  FIGS. 13 and 14 show a sixth embodiment. In this embodiment, a ring member 28 as a holding member is mounted on the tail cord 7, and a guide rail 29 is vertically installed inside the storage duct 10. The guide rail 29 is provided with a slider 30 slidable in the axial direction of the guide rail 29, and the ring member 28 is connected to the slider 30 via a chain 31.

  The tail cord 7 is loosely inserted inside the ring member 28 so as to be movable. The ring member 28 is supported via the chain 31 in a region where the ring member 28 is engaged with the tail cord 7 at a portion facing the opening 11 of the storage duct 10 and does not protrude from the opening 11.

  The ring member 28 is disposed by its own weight in the vicinity of the U-shaped bent portion of the lower end portion of the tail cord 7 and faces the opening 11. When the tail cord 7 moves up and down together with the car in this state, The ring member 28 also moves up and down along a guide rail 29 connected via a chain 31. The ring member 28 restrains the tail cord 7 on the inner side and holds the state facing the opening 11.

  Therefore, when the tail cord 7 swings in the storage duct 10 and the portion facing the opening 11 tries to jump out through the opening 11, the tail cord 7 is connected to the guide rail 29 via the chain 31 by the ring member 28. The movement of the cord 7 is restricted and the jumping out is suppressed. For this reason, it is possible to prevent the tail cord 7 from being damaged by the protrusion.

  In the first to fifth embodiments, since the stopper member 20 is attached to the tail cord 7, the stopper member 20 abuts against the inner wall surface of the storage duct 10 to generate a certain amount of noise, and the stopper member. In the case of this sixth embodiment, the tail cord 7 is passed through the ring member 28 and the movement of the tail cord 7 is restricted by the ring member 28 to prevent the tail cord 7 from popping out. Therefore, almost no noise is generated, and the ring member 28 is hardly damaged.

  The present invention is applied to an elevator of a type in which a hoistway is formed in a building, and a car moves up and down inside the hoistway, as well as an outdoor type elevator as shown in FIG. The present invention can be similarly applied to an elevator in which the car is disposed so as to be exposed to the outside of the building and the car moves up and down on an open path outside the building.
