Japanese Unexamined Patent Publication No. 11-171446

However, the landing threshold of Patent Document 1 can adjust the height and the horizontal position of the landing threshold, but cannot adjust the inclination of the landing threshold. Therefore, when the floor of the landing is not horizontal, it is necessary to incline the landing threshold by using a wedge member or the like in order to make the upper surface of the landing threshold flush with the floor of the landing.

The present invention has been made to solve the above-mentioned problems, and even when the floor surface of the landing is inclined, the upper surface of the landing threshold and the floor of the landing are not used without using a wedge member or the like. It obtains a position adjustment structure of the landing threshold that can be flush with the surface.

The position adjusting structure of the landing threshold according to the present invention includes a mounting member fixed to the floor of the landing of the elevator to support the landing threshold, and the mounting member has a mounting member curved surface that curves in the direction of getting on and off the car. However, by moving the landing threshold along the curved surface of the mounting member, the inclination angle of the landing threshold in the direction perpendicular to the longitudinal direction of the landing threshold can be adjusted.

INDUSTRIAL APPLICABILITY The present invention makes it possible for a receiving member that supports the landing threshold to rotate within a certain angle in a direction perpendicular to the longitudinal direction of the landing threshold with respect to a mounting member that supports the receiving member and fixes it to the floor of the landing. Therefore, the upper surface of the landing threshold can be tilted. As a result, the upper surface of the landing threshold and the floor surface of the landing can be made flush with each other.

The landing threshold 20 guides the lower part of the landing door of an elevator (not shown) by a groove 20a formed along the longitudinal direction. Further, the landing threshold 20 closes a gap between the elevator car and the floor 10 of the entrance 1 (not shown), and prevents an object from falling into the hoistway from the gap.

As shown in FIG. 2, the position adjusting structure 2 of the landing threshold of the first embodiment has a receiving member 30 and a mounting member 40. The receiving member 30 is fixed below the landing threshold 20 by a fixing member 70 such as a screw. The mounting member 40 supports the receiving member 30 from below and is fixed to the floor 10 by anchor bolts 71. The receiving member 30 and the mounting member 40 are fixed to each other by the adjusting screw 72. Although two sets of the position adjusting structures 2 of the landing threshold are shown in FIGS. 1 and 2, the number of the position adjusting structures 2 of the landing threshold is not limited to this. For example, depending on the specifications of the elevator, there may be three or more sets, or they may be integrated.

FIG. 3 is a cross-sectional view showing the landing threshold 20 and the position adjusting structure 2 of the landing threshold along the line III-III of FIG. FIG. 4A is a cross-sectional view showing a receiving member 30 constituting the position adjusting structure 2 of the landing threshold of FIG. FIG. 4B is a front view of the receiving member 30. Further, FIG. 5A is a cross-sectional view showing a mounting member 40 constituting the position adjusting structure 2 of the landing threshold of FIG. FIG. 5B is a front view of the mounting member 40.

As shown in FIGS. 3 and 4A, the receiving member 30 is formed by bending a long plate-shaped member such as a steel plate.

The receiving member 30 is fixed to the landing threshold 20 by the fixing member 70 inserted into these elongated holes 30c. The landing threshold 20 can adjust the position of the elevator boarding / alighting direction HD within the range of the elongated hole 30c.

As shown in FIGS. 3 and 5A, the mounting member 40 is formed by bending a rectangular plate-shaped member such as a steel plate. A curved surface 40a of the mounting member is formed on one end side of the mounting member 40. The curved surface 40a of the mounting member is provided with an elongated hole 40b along the bending direction.

Further, the mounting member 40 has a plurality of elongated holes 40c along the vertical VD shown in FIG. The mounting member 40 is fixed to the floor 10 by anchor bolts 71 inserted into these elongated holes 40c. Thereby, the landing threshold 20 can adjust the position of the vertical VD within the range of the elongated hole 40c.

The outer diameter of the receiving member curved surface 30a of the receiving member 30 is formed to be substantially equal to the inner diameter of the mounting member curved surface 40a of the mounting member 40. Then, as shown in FIG. 3, the receiving member curved surface 30a of the receiving member 30 is arranged inside the mounting member curved surface 40a of the mounting member 40. As a result, the receiving member 30 can rotate in the RD1 direction shown in FIG. 3 inside the curved surface 40a of the mounting member 40.
