Abstract

(57) [Summary] [Purpose] To provide elevator door shoes that can cope with uneven wear of sill grooves. [Structure] A sliding portion 4 attached via a shaft 9 provided at the center to a horizontal portion of an L-shaped bracket 3 attached along a sill groove 2 is made angularly displaceable about the shaft 9, and The displacement can be adjusted in the width direction of the groove 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator door shoe mounted in a sill groove.

[0002]

[Prior art]

 As described in Japanese Utility Model Laid-Open No. 58-134569, a conventional device is mounted on a lower end of a door, on a horizontal portion of an L-shaped bracket mounted along a sill groove, through a shaft provided at the center. In addition to being reciprocally fitted in the sill groove with a predetermined gap, the sliding portion can be angularly displaced about the shaft.

[0003]

[Problems to be solved by the device]

 By the way, the sill groove that guides the door shoe of the elevator wears due to sliding friction with the door shoe, but it was caused by some impact such as strong wind blowing from the landing side toward the hoistway side in the environment where the elevator was installed. There may be uneven wear on one side of the sill groove due to door distortion or the like. However, in the conventional device described above, the shaft for attaching the door shoe to the horizontal portion of the L-shaped bracket cannot be displaced in the width direction of the sill groove. There was a problem that it was not possible to make adjustments so that there was a predetermined gap between them.

An object of the present invention is to provide an elevator door shoe that can cope with uneven wear of a sill groove.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is directed to an L-shaped bracket which is attached to a lower end of a door along a sill groove, and a horizontal portion of the L-shaped bracket which is attached via a shaft provided at the center. In an elevator door shoe that includes a sliding portion that is freely reciprocally fitted in a sill groove with a predetermined gap and is angularly displaceable about the shaft, the shaft is provided with the horizontal portion. On the other hand, it can be displaced in the width direction of the sill groove.

[0006]

[Action]

 According to this invention, the shaft having the sliding portion attached to the horizontal portion of the L-shaped bracket can be displaced in the width direction of the sill groove. Thus, it is possible and easy to adjust such that a predetermined gap is provided between the door shoe and both sides of the sill groove.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a plan view showing a door shoe parallel installation state of a door shoe showing an embodiment of the present invention, and FIG. 2 is a plan view showing an eccentric attachment state of the door shoe of FIG.

In the figure, 1 is a sill, 2 is a sill groove for guiding a sliding portion 4 of a door shoe attached to the lower end of the door, 3 is an L-shaped bracket attached to the lower end of the door for supporting the door shoe, and 4 is An elongated hole provided in the horizontal portion 3a of the L-shaped bracket for adjusting displacement of the shaft 9 of the door shoe in the width direction of the sill groove 2, 5 is a nut for fixing the shaft 9 to the horizontal portion 3a, and 6 is in the sill groove 2 Is a sliding portion of a door shoe that reciprocates with a gap G set to the left and right, 7 is an arcuate slot provided in the horizontal portion 3a, and 8 is a screw for fixing the sliding portion 6 to the horizontal portion 3a. .

In the above configuration, assuming that the sill groove 2 on the upper side of the paper surface is worn on one side from the position of the original two-dot chain line to the position of the solid line as shown in FIG. While being moved to the upper side, the entire sliding portion 6 is angularly displaced about the shaft 9 and tightened after displacement adjustment so that the gaps on both sides of the sill groove 2 become a predetermined G.

[0010]

[Effect of device]

 According to this invention, the shaft having the sliding portion attached to the horizontal portion of the L-shaped bracket can be displaced in the width direction of the sill groove. Thus, it is possible and easy to adjust such that a predetermined gap is provided between the door shoe and both sides of the sill groove.

[Brief description of drawings]

FIG. 1 shows an embodiment of the present invention and is a plan view showing a state in which a door shoe is mounted in parallel with a sill groove.

FIG. 2 is a plan view showing the door shoe of FIG. 1 in the same eccentric mounting state.
