Field of the Invention The present invention relates to a guide device for supporting and guiding an elevator door installed at an entrance of an elevator platform or an elevator car to open and close the elevator door in left and right directions and more specifically to a guide device for guiding the lower portion of the elevator door, And a guide groove of the elevator door is concealed so that foreign matter is not caught in the guide groove of the guide plate.

The elevator is a device for carrying people or cargo by moving up and down along a vertical hoistway inside the building, and an elevator door is installed at the entrance to allow people or cargo to be carried. The elevator door is composed of a car door opened and closed in the elevator car and a platform door opened and closed at the platform. When the elevator car reaches each floor, the car door and the platform door are engaged with each other, A clutch device is provided.

1, a hanger roller unit 40 is fixed to an upper portion of the elevator door 30 so that the elevator door can be safely slid while keeping the elevator door. 51 and the door shoe 250 is fixed to the lower portion of the elevator door and inserted into the guide groove 110 of the guide plate 100 fixed to the floor. That is, the lower portion of the elevator door is inserted into the guide groove in a state where the upper portion of the elevator door is suspended, and is opened / closed laterally.

On the other hand, when people enter and exit the elevator, various foreign substances such as soil adhered to the shoe are introduced into the elevator, which is gradually accumulated in the guide groove of the guide plate. For this reason, the manager has to clean it from time to time, and if the cleaning is not properly performed, the elevator door is hampered by friction and noise during sliding. Particularly, when the elevator door is opened and closed, foreign substances accumulated in the guide groove are gathered at the central portion of the guide groove, thereby hindering the closing operation of the elevator door.

Various types of elevator door guide devices have been proposed to prevent this. 2, a door shoe 250 coupled to a lower portion of an elevator door 30 is installed in the upper portion of the elevator door 30, A brush fixing portion 150 is formed in an opening of the guide groove 110 and a pair of brushes 160 coupled to the brush fixing portion are inserted into the guide groove 110 of the guide plate 100, The door 30 is configured to slide. However, since the openings of the guide grooves 110 are directed upward, not only foreign substances can be prevented from flowing in, but also foreign substances that have been clogged by the brushes are dropped and accumulated in the guide grooves by opening and closing operations of the elevator doors.

As another example, as shown in FIG. 3, a door shoe 250 is provided on both lower sides of an elevator door 30, as disclosed in Korean Patent No. 10-1062083, And the latch bracket 260 is fixed between the door shoe to prevent the elevator door from being separated. The guide groove 110 formed in the guide plate 100 is formed in an upward direction to allow foreign matter to flow therein. In order to block the foreign matter, an intermediate bent portion 261 is formed in the latching bracket 260 However, even if the thickness of the intermediate bent portion is increased, the gap can not be completely closed, and rather, the gap between the locking bracket 260 and the guide plate 260 can be reduced, Friction and noise can be increased only between the first and second electrodes 100a and 100b.

In addition, in the above conventional art, there is a problem in that the guide grooves 110 of the guide plate 100 are exposed to the view of people entering and leaving the elevator, which is not good for cosmetics.
