An elevator landing apparatus including a detector mounted on one of a doorsill part of a cage of an elevator provided in an elevator shaft and a doorsill part of an elevator hall, and a detected member mounted on the other of the doorsill part of the elevator hall and the doorsill part of the cage. The detector and detected member are configured to position the cage at a position where the doorsill part of the elevator hall and the doorsill part of the cage are flush with each other when the detector and the detected member are opposite each other. The one of the detector or the detected member provided on the doorsill part of the cage is mounted along a side of the cage and facing toward a side of the elevator shaft. The other of the detected member or detector provided on the doorsill part of the elevator hall is mounted extending from the doorsill part of the elevator hall to be opposite the one of the detector or detected member mounted along the side of the cage between the side of the elevator shaft and the one of the detector or detected member mounted along the side of the cage.
This application claims benefit of priority to Japanese Patent Application Nos. JP10-252680 filed Sep. 7, 1998, and JP11-046391 filed Feb. 24, 1999, the entire disclosure of which is incorporated by reference herein.
An object of the present invention is to provide a novel elevator landing apparatus, capable of installation with reduced labor so as to lower the installation cost, and capable of preventing malfunction so as to reliably position the cage at a position where the doorsill parts of the elevator hall and the cage are flush with each other.
FIG. 6 is a diagram for explanation along the line VI—VI in FIG. 5;
FIG. 7 is a cross-sectional view taken on the line VII—VII in FIG. 5;
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, according to a first embodiment of the present invention shown in FIG. 4. There is provided a landing apparatus 31 of an elevator 1 for stopping a cage 4 of the elevator 1 so as to be positioned at the position where the doorsill part 32 (shown in FIG. 5) of the cage 4 and the doorsill part 34 of an elevator hall 33 (shown in FIG. 5) are flush with each other.
The detected member 36 is formed as a sheet metal integrally having the mounting part 45 and the reflecting part 46. The mounting part 45 is mounted on the surface 34 a of the doorsill part 34 of the elevator hall 33 facing the doorsill part 32 of the cage 4. The mounting part 45 is formed along the surface 34 a, elongating downward from the surface 34 a.
The reflecting part 46 is formed by bending the end part 45 a of the mounting part 45 on the rim of the doorsill part 34 along the side plate 14 of the cage 4 so as to face with the light emitting part 38 and the light receiving part 39 of the detector 35. The reflecting part 46, configured to reflect and to guide a light beam from the light emitting part 38 of the detector 35 to the light receiving part 39, is composed of a material or a member which can reflect a light beam with a high efficiency, such as a metal plate or plating having a mirror finished surface.
X<L1<L2 (1)
Moreover, the detected member 36 is disposed at a position so as to have a distance L3 between the reflecting part 46 and the door rim 12 a when the door 12 is opened to its full width. The detected member 36 is disposed at a position so as not to disturb opening or closing of the door 12.
The aprons 51, 52 mounted on the surfaces 32 a, 34 a of the doorsill parts 32, 34 facing with each other, are formed like a sheet metal elongating downward from the surfaces 32 a, 34 a.
In the above-mentioned embodiment, in installing the aprons 51, 52 on the doorsill parts 32, 34, respectively, the mounting flange 37 can be formed integrally with the apron 51 as shown in FIG. 10, and the reflecting part 46 of the detected member 36 can be formed integrally with the apron 52 as shown in FIG. 11.
1. An elevator landing apparatus comprising:
a detector mounted on one of a doorsill part of a cage of an elevator provided in an elevator shaft and a doorsill part of an elevator hall; and
a detected member mounted on the other of the doorsill part of the elevator hall and the doorsill part of the cage, said detector and detected member configured to position said cage at a position where said doorsill part of the elevator hall and the doorsill part of the cage are flush with each other when the detector and the detected member are opposite each other,
the one of the detector or the detected member provided on the doorsill part of the cage being mounted along a side of the cage and facing toward a side of the elevator shaft; and
the other of the detected member or detector provided on the doorsill part of the elevator hall mounted extending from the doorsill part of the elevator hall to be opposite the one of the detector or detected member mounted along the side of the cage between the side of the elevator shaft and the one of the detector or detected member mounted along the side of the cage.
2. The elevator landing apparatus as recited in claim 1, wherein:
the cage has a door configured to face the elevator hall, and the other of the detector or the detected member provided on the doorsill part of the elevator hall is disposed at a position so as not to disturb opening or closing of the door.
3. The elevator landing apparatus as recited in claim 1, wherein:
the detector comprises a light emitting part configured to emit a light beam and a light receiving part configured to receive the light beam, and the detected member comprises a reflecting part for reflecting the light beam from the light emitting part to the light receiving part.
4. The elevator landing apparatus as recited in claim 3, wherein:
L1 is a maximum distance between the detector and detected member at which the light receiving part can receive light emitted by the light emitting part and reflected off the detected member,
L2 is a distance between the one of the detector or the detected member mounted on the side doorsill part of the cage and a wall surface of the elevator shaft, and
X is a distance between the detector and the detected member, and
X<L1<L2.
5. The elevator landing apparatus as recited in claim 1, further comprising:
an apron provided at the doorsill part of the elevator hall,
the other of the detector or the detected member being provided on the doorsill part of the elevator hall being mounted on the apron.
6. The elevator landing apparatus according to claim 1, comprising:
