Abstract

(57) [Summary] [Purpose] To provide an entrance / exit of a skew elevator that can secure an effective entrance / exit width even if a level error occurs. [Structure] The entrance / exit is configured such that the entrance / exit width B on the car 9 side is larger than the entrance / exit width A on the hall side. [Effect] The effective entrance / exit width can be secured regardless of the presence or absence of a level error in the oblique elevator.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an entrance / exit of a skew elevator.

[0002]

[Prior Art]

 As a conventional relationship between the entrance and exit on the side of the hall and the entrance and exit on the side of the car, for example, as shown in FIG. 2 of Japanese Utility Model Application Laid-Open No. 57-196073, generally, the width of the entrance and exit on the side of the car and the side of the car The width of the doorway was the same.

When the entrance width on the hall side and the entrance width on the car side are the same, when a landing error occurs between the car and the entrance on the hall side in a general elevator that moves up and down, that is, a level error is generated. Even if it occurs, there will be a step between the sill of the car and the sill on the side of the hall, and the effective entrance width can be secured without any change. However, in the case of a skew elevator, when a level error occurs, the car moves diagonally with respect to the entrance on the hall side, so the entrance on the hall side and the entrance on the car side shift relatively to the left and right. As a result, there was a problem that not only a level difference could be created between the sill of the car and the sill on the side of the hall, but also the effective entrance width could not be secured.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide an entrance / exit of a skew elevator that can secure an effective entrance / exit width even when a level error occurs.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the entrance / exit of the oblique elevator of the present invention is characterized in that the entrance / exit width on the car side is larger than the entrance / exit width on the hall side.

[0006]

[Effect] By making the width of the entrance and exit on the car side larger than the width of the entrance and exit on the hall side by the amount of shift in the left and right direction of the car due to a level error, the entrance and exit width on the car side is always maintained even if a level error occurs. Since the entrance / exit width on the side of the hall is covered, an effective entrance / exit width can be secured.

【Example】

 Hereinafter, an embodiment of the entrance and exit of the oblique elevator of the present invention will be described with reference to the drawings. As shown in FIG. 2, an oblique elevator is a device that ascends and descends in a hoistway 1 having an inclination angle along the inclination, and is a wire rope suspended by a hoist 3 installed in an elevator machine room 2. 5 is converted in direction by a sheave 4 and is connected to a carriage 7 and a balance weight (not shown) that move along the inclined surface. The dolly 7 is configured to run on the upper surface of the laid guide rail 6 along the floor surface of the inclined hoistway 1. Figure 1 shows the plane of the entrance and exit of the car and the hall. Elevator doors usually consist of double doors, a hall door 8 installed on the side of the hall in the building and a car door 10 installed on the side of the car 9 of the elevator. In addition, the car door 10 is hung from the top at the car entrance. As shown in Fig. 1, when the level of the car 9 and the entrance of the hall are the same, the center of the entrance on the side of the wheel and the center of the entrance on the side of the car are the same, so the effective entrance width (in this case Is the A dimension). Further, a case where the car stops in a state where the level is changed to the mountain side or the valley side of the slope with respect to the entrance on the hall side will be described with reference to FIGS. 3, 4 and 5. When the level goes wrong, the car moves diagonally to the entrance / exit of the hall, so the entrance / exit width A on the hall side and the entrance / exit width B on the car side are relatively shifted in the left-right direction. The shaded area in Fig. 3 shows the entrance and exit area on the hall side. At this time, the effective entrance / exit width A can always be secured by adding the value of the lateral shift C due to the level error of the car and the effective entrance / exit width A to the entrance / exit width B on the car side. it can.

[0008]

[Effect of the device]

 According to the present invention, a level error is caused by increasing the entrance / exit width on the car side of the entrance / exit width on the side of a hall in an oblique elevator that moves up and down on a guide rail laid along the inclined surface of an inclined hoistway. Even if a problem occurs, the entrance width on the car side always covers the entrance width on the hall side, so an effective entrance width can be secured.
