[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door device, and more particularly to an elevator door device attached to a lower end of a door and slidingly guiding the door.

[0002]

[Prior Art]

 Generally, a door device of an elevator equipped with a sideways-suspended door, a door shoe attached to the lower part of the sideways-suspended door, and a sill having a groove part for slidingly guiding the door shoe, has a foreign matter in the groove part provided in the sill. There is a possibility that the doorshoe will be locked due to the entry of a sill, and in order to solve this problem, as described in Japanese Utility Model Laid-Open No. 63-45772, the sill is composed of a guide part and a guide support, and the sill is There has been proposed a technology in which the upper surface of the vehicle is made flat and a guide portion for slidably guiding the door shoe is detachably screwed and supported to the lower side.

[0003]

[Problems to be solved by the device]

 In the conventional device, since the door shoe slides on the guide portion, the door moves back and forth, which may cause an abnormal sound during the operation of the door. Further, the guide part may come into contact with the door shoe, the door shoe may be worn, and the frictional resistance may increase the opening / closing time of the door, which may eventually cause the door to be unable to open / close.

An object of the present invention is to provide an elevator door device capable of preventing abnormal noise during door operation and preventing dust accumulated on a sill and door opening / closing abnormality due to frictional resistance of door shoes. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a door device for an elevator including a horizontal suspension door and a sill for slidingly guiding the door at a lower portion of the horizontal suspension door, wherein the upper surface of the sill is flat. And a rail provided at a lower portion of the sill and having a length for operating the door at least, and a plurality of guide rollers that roll by fitting the rail at a lower portion of the door. It is a thing.

[0006]

[Action]

 With this structure, the rail provided at the lower portion of the sill and the plurality of guide rollers provided at the lower portion of the door are fitted to each other, so that the door does not rattle. In addition, since the guide roller attached to the lower part of the door slides on the rail surface, there is no change in the sliding resistance, and the change over time in the door opening / closing time is reduced. For this reason, the noise when the door is opened and closed is reduced, and the period for adjusting the door opening and closing time and the parts replacement is extended.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, for example, a bracket 1b is fixed to the lower hoistway surface of a floor 1F on the first floor with anchor bolts 1a, and a floor 2 of the bracket 1b is flush with the floor 1F and a floor 2 is a nut 2a. It is fixed. A rail 3 is fixed to the hoistway wall 1C below the sill 2. Further, a guide support 4 is attached to the lower portion of the landing door 1D on the first floor, and a guide roller support fitting 5 is fixed to the guide support 4 with a screw 4a. Pins 5a are respectively hung at positions facing each other around the rail 3, and a plurality of guide rollers 5b1 to 5b3 are attached to the pin 5a so as to sandwich the rail 3. Here, the alignment of the rail 3 and the guide rollers 5b1 to 5b3 may be performed by finely adjusting the mounting of the guide roller support fitting 5.

When the hall door 1D opens and closes, the roller 5b1 and the rollers 5b2 and 5b3 rotate while sandwiching the rail 3.

Although the landing door 1D has been described in the present embodiment, the same applies to the car door, and a description thereof will be omitted. Also, it goes without saying that when the car is applied to the car door, rattling noise of the car door due to wind pressure during running of the car can be prevented.

Further, in the present embodiment, the rollers 5b1 to 5b3 are described as sandwiching the rail 3 from above, but the same effect can be obtained by sandwiching the rail 3 from below.

In this embodiment, the rollers 5b1 to 5b3 sandwiching the rail 3 are attached to the guide roller support fitting 5, and the rollers 5b1 to 5b3 are attached to the left and right lower ends of the landing door 1D. The same effect can be obtained by mounting one rail, sandwiching the rail 3 at the lower left end of the door, the lower center end of the door, and the lower right end of the door.

[0013]

[Effect of the device]

 According to the present invention, the rail provided at the lower portion of the sill and the plurality of guide rollers provided at the lower portion of the door are fitted to each other, so that the door does not rattle. In addition, since the guide rollers attached to the lower part of the door slide on the rail surface, there is no change in sliding resistance and the change in door opening / closing time over time is reduced. For this reason, noise at the time of opening and closing the door is reduced, and it is possible to lengthen the period for adjusting the door opening and closing time and replacing parts.
