Description

  The present invention relates to an elevator car, and more particularly to an elevator car suitable for reducing the height dimension of a car frame.

  In general, the car is configured as shown in FIGS. That is, a floor plate 1, a side plate 2 erected from the peripheral edge of the floor plate 1, a ceiling 3 that closes the top of the side plate 2 and is formed in a hat shape, and an entrance / exit 4 formed in a part of the side plate 2, A car room 6 having a car door 5 that opens and closes the doorway 4; a pair of left and right vertical frames 7A and 7B facing the left and right side plates 2 adjacent to the doorway 4 of the car room 6 with a gap, respectively; A car frame 10 having a cross head 8 for connecting the upper ends of the vertical frames 7A and 7B and a support frame 9 for connecting the lower ends of the vertical frames 7A and 7B. The cab 6 is mounted on a support frame 9, a part of the peripheral edge 3E of the ceiling 3 is bent upward, a bent portion 3B bent upward and the pair of left and right vertical frames 7A, 7B Between the left and right vertical frames 7A and 7B. Are provided guide means 12 for engaging with the laid guide rails respectively hoistway at the bottom.

  Patent Document 1 is cited as a reference technique.

  In order to reduce the influence on the building of the elevator equipment equipped with the elevator car having the above structure, when the car is stopped on the top floor of the hoistway, the distance between the car top and the hoistway ceiling That is, it is desired to reduce the head clearance as much as possible.

  Therefore, as shown in FIG. 7, it is conceivable to reduce the head clearance by reducing the height of the ceiling 3 and reducing the height of the vertical frames 7A and 7B accordingly. When the height dimension of the ceiling 3 is lowered, the installation position of the upper guide means 12 is also displaced downward accordingly. For this reason, the bent portion 3B on the upper side of the ceiling 3 that supports the vibration isolating means 11 is in a state of closing the back side of the upper guide means 12, and from the work space OP secured on the back side. The guide means 12 is attached and detached and maintenance inspection is limited, which is not a good idea.

  An object of the present invention is to provide an elevator car in which the height of the car frame can be reduced and the head clearance can be reduced without restricting the attachment and detachment of the guide means installed at the upper part of the car frame and the maintenance inspection. is there.

In order to achieve the above object, the present invention provides a floor panel, a side panel erected from the peripheral edge of the floor panel, a ceiling formed in a hat shape that closes the top of the side panel, and a part of the side panel. Forming a cab having a car door that opens and closes the door, and a pair of left and right vertical frames, a crosshead connecting the upper ends of the vertical frames, and a lower end of the vertical frames A car frame having a support frame to be connected is formed, the car room is mounted on the support frame of the car frame, and vibration isolating means are interposed between the pair of left and right vertical frames and the peripheral edge of the ceiling And an elevator car provided with guide means for engaging with guide rails laid in the hoistway at the upper and lower portions of the pair of left and right vertical frames, respectively, The car frame is supported by a bent portion bent downward. Between the installation position and the ceiling of the periphery of the guide means for the upper, it was to form a working space.

  With this configuration, there is no member supporting the vibration isolating means on the back side of the guide means, so that a work space can be secured on the back side of the guide means and the height of the car frame is reduced. Therefore, the head clearance can be reduced.

  As described above, according to the present invention, the height of the car frame can be reduced and the head clearance can be reduced without restricting attachment / detachment of the guide means installed on the upper part of the car frame and maintenance inspection. You can get a basket.

  Hereinafter, an embodiment of an elevator car according to the present invention will be described with reference to FIGS.

  The basic configuration of the car in the present embodiment is the same as the configuration of the conventional car shown in FIGS. 1 to 6, and therefore the description thereof is omitted. Here, only the configuration different from the conventional car is described here. explain.

The difference from FIGS. 1 to 6 is that the height dimension of the ceiling 3 having an upwardly convex hat-shaped cross-sectional shape is reduced without changing the height dimension in the cab 6, and a pair of left and right parts are correspondingly reduced. The height dimensions of the vertical frames 7A and 7B are reduced. Thus, by reducing the height dimensions of the vertical frames 7A and 7B, the position of the upper guide means 12 supported by the upper ends of the vertical frames 7A and 7B is naturally displaced downward. Then, a part of the peripheral edge portion 3E of the ceiling 3 is bent downward, and the anti-vibration means 11 in contact with the vertical frames 7A and 7B is supported by the bent portion 3B bent downward.

  With this configuration, as shown in FIG. 9, a work space OP having no obstacles is formed on the back side of the guide unit 12, specifically, between the vertical side 3 </ b> V of the ceiling 3 and the guide unit 12. Since the work space OP is formed, the guide means 12 can be attached / detached and the maintenance / inspection work can be performed.

  Therefore, according to the present embodiment, the height of the car frame 10 can be reduced without restricting the attachment and detachment of the guide means 12 installed on the upper part of the car frame 10 and the maintenance inspection, so the head clearance is reduced. be able to.

  Incidentally, in the embodiment described above, a part of the peripheral edge portion 3E of the ceiling 3 is bent downward, and the vibration isolating means 11 is supported by the bent portion 3B bent downward. However, the vibration isolating means 11 may be configured to be supported by another member that extends downward and is attached to the peripheral edge portion 3E of the ceiling 3. Specifically, the horizontal side of the inverted L-shaped mounting bracket is fixed to the peripheral edge portion 3E of the ceiling 3 by a known fixing means such as screwing or welding, and the vertical side extending below the fixed mounting bracket The anti-vibration means 11 is supported. By comprising in this way, besides having the same effect as the said embodiment, the work process and material for bending the peripheral part 3E of the ceiling 3 below can be saved.

A side view showing a conventional elevator car. The front view of FIG. The top view which shows the ceiling of the passenger car of FIG. FIG. 4 is a front view of FIG. 3. FIG. 2 is an enlarged view showing a positional relationship among a vertical frame, guide means, and vibration isolation means of the car in FIG. Sectional drawing which follows the AA line of FIG. FIG. 6 is a diagram corresponding to FIG. FIG. 4 is a view corresponding to FIG. 4 showing a ceiling according to an embodiment of the elevator car of the present invention.
