Description

  The present invention relates to an elevator car, and more particularly to a car having a reduced overall size.

  Recently, the structure of elevator cars has come to be of a suspended type in which a hanging rope is hung on the lower side of the car to raise and lower the car room. An example of the structure of a hanging type passenger car is shown in FIG. FIG. 8 is a schematic cross-sectional view of the car as viewed from the front. In the car 1, a frame called a car frame is formed by the upper beam 2, the lower beam 3, and the standing frame 4. A car room 6 is provided inside the car frame via an elastic body 5 for vibration isolation.

  On both sides of the car 1, guide rails 7 for guiding the raising and lowering of the car 1 are provided. Guide devices 8 that engage with the guide rails 7 are attached to the upper and lower portions of the car frame. A sheave support beam 9 for supporting the sheave 10 is attached to the lower side of the car frame. Sheaves 10 are attached to both ends of the sheave support beam 9. A suspension rope 11 is placed on the lower side of the car 1 so as to pass through the sheave 10, and the car 1 is driven to move up and down along the guide rail 7 by the suspension rope 11.

  Next, an example of the structure of the cab 6 is shown in FIG. FIG. 9 is a schematic cross-sectional view of the cab 6 when viewed from the front. The cab 6 is composed of a floor 12 on which passengers ride, a side plate 13 serving as a side wall, and a ceiling 14 on which lighting devices and the like are disposed. The portion of the side plate 13 and the ceiling 14 facing the inside of the car room 6 is a portion that is in contact with the passengers of the car 1 and is therefore a decorative surface. On the other hand, a reinforcement (not shown) or the like is attached to a portion facing the outside of the cab 6.

  In recent years, a reduction in hoistway space in a building in which an elevator is installed has been demanded. However, in the car 1 having the conventional car frame as shown in FIG. 8, the guide device 8 is attached to the upper part of the upper beam 2 of the car frame. Therefore, the prescribed space for securing at the top of the hoistway is large. Further, in the plane direction, since the car frame is located outside the car room 6 in which passengers enter, the necessary space for the car is large, and it is difficult to reduce the hoistway space.

  Various proposals have been made to reduce the hoistway space. For example, there has been proposed a car structure in which the car room itself has rigidity so that a car frame is not required and the guide device is directly attached to the car room (see, for example, Patent Document 1).

  In addition, as a car structure in which a rope is wound between a standing frame and a car room, a structure in which the pit depth can be shortened has been proposed (for example, see Patent Document 2).

JP 2004-123273 A JP 2008-162717 A

  However, in the structure proposed in Patent Document 1, since vibration transmitted from the rope is not insulated, vibration is propagated to the car room, and noise in the car room becomes a problem.

  Further, in the structure proposed in Patent Document 2, a standing frame is arranged outside the car room, and a rope is arranged between the car room and the standing frame. Not suitable.

  Therefore, the present invention has been made in view of the above-described problems, and provides a car structure that can reduce the hoistway space without significantly deteriorating the performance against noise in the car room. .

  According to one aspect of the present invention, the car is disposed between the pair of guide rails, and the car is driven to be able to move up and down along the guide rails via the suspension ropes hung under the car. The elevator car structure is constructed by assembling a car frame of a car from a vertical strength member on the side of the car, a horizontal strength member at the top of the car, and a horizontal strength member at the bottom of the car, The horizontal strength member at the lower part of the car is supported by vibration isolation through an elastic body, and has a sheave for towing the car through the suspension rope. An elevator car structure is provided in which a decorative member is attached.

  Further, according to another aspect of the present invention, the car is disposed between the pair of guide rails, and the car can be moved up and down along the guide rails via a suspension rope that extends over the lower side of the car. The elevator car structure is driven by a vertical strength member on the side of the car, a horizontal strength member at the top of the car, and a horizontal strength member at the bottom of the car. An assembling structure comprising a sheave for pulling the car through the suspension rope and supported by a horizontal strength member at the lower part of the car through an elastic body, and having a horizontal strength member at the upper part of the car. Further, there is provided an elevator car structure in which a decorative member for a car room is attached.

  Further, according to another aspect of the present invention, the car is disposed between the pair of guide rails, and the car can be moved up and down along the guide rails via a suspension rope that extends over the lower side of the car. The elevator car structure is driven by a vertical strength member on the side of the car, a horizontal strength member at the top of the car, and a horizontal strength member at the bottom of the car. An assembled structure is supported by the horizontal strength member at the lower part of the car in an anti-vibration manner through an elastic body, and includes a sheave for towing the car through the suspension rope. There is provided an elevator car structure in which an interior decorative member is attached.

   According to the present invention, it is possible to reduce the size required for the car in the hoistway space. Further, the elastic support of the sheave support beam can improve the performance against vibration and noise.
