The present invention relates to a door holding device of an elevator station, and in particular to form a guide groove for guiding the door fixed to the sliding door of the platform sideways in the vertical portion of the door to prevent the accumulation of dust in the guide groove And it relates to a door holding device of the elevator platform that facilitates the movement of the wheeled moving body without damaging the door area, and facilitate the production and installation process of the door.

In general, elevators are each sliding doors are installed on the elevator and the platform of each floor, the above sliding doors are suspended by guide rails and guide rollers at the upper part, and several doors are guided by the guide groove of the door at the lower part. It is fixed and opened and closed by the interlocking operation with each other.

An embodiment of the landing gate door apparatus according to the prior art for guiding the sliding door of the landing among the sliding doors as described above will be described with reference to FIG.

In the drawing, 1 shows a platform for passengers to get on and off, 2, 2 'shows a sliding door of platform 1, 3 shows a lift where an elevator (not shown) is lifted, and 4 is a concrete system. Each building is shown.

The step portion 5 is formed at the front end of the hoistway 3 side of the building 4, and a support 6 protruding from the wall surface to a predetermined thickness l is formed.

The threshold 8 supported by the support plate 7 is fixed to the stepped portion 5 of the building 4 by concrete, and the lower threshold of sliding doors 2 and 2 'is attached to the threshold 8. Guide grooves 8a to which the door legs 9 and 9 'fixed to the guide can be formed are formed.

In addition, a toe guard 10 is fixed to the front end surface of the threshold 8.

The sliding doors 2 and 2 'of the landing 1 by the door holding device of the elevator landing structure configured as described above have several door legs 9 and 9' fixed to their lower ends with the door holding 8 While being guided to the guide groove (8a) of the) is linked to the sliding door of the elevator, the normal opening and closing operation is performed.

However, the door threshold device of the landing as described above, the doors (9), (9 ') of the sliding doors (2), (2') is guided, the guide groove (8a) of the door (8) is formed upward Therefore, foreign matters such as dust accumulate in the guide groove 8a, so there is a problem that the opening and closing operations of the sliding doors 2 and 2 'are not smooth, as well as when loading or unloading wheeled moving objects such as wheelchairs. The moving body vibrates violently due to the guide groove 8a of the threshold 8 or the guide groove 8a of the threshold 8 wears.

In addition, the shape of the door (8) is complicated, the production is not easy, there was a problem that the installation work is not easy, such as the use of concrete for fixing the door (8).

The present invention has been devised to solve the conventional problems as described above, by forming a guide groove in which the door of the sliding door is guided in the vertical portion of the door side to prevent the accumulation of dust in the guide groove and guide groove In addition to facilitating the movement of the wheeled body without damage to the site, the shape of the door can be simplified and the door can be easily fixed to the stud bolts installed on both sides of the building as nuts to facilitate the manufacture and installation of the door. It will be configured so that it will be described by the accompanying drawings as follows.

As shown in FIG. 3 and FIG. 4, the threshold 14 provided with the guide groove 14a is fixed to the front end of the building 13 on the side of the hoistway 12 on which the platform 11 is formed. In the guide groove 14a of 14, the doors 16 and 16 'are fixedly inserted into the lower ends of the sliding doors 15 and 15', and the vertical portion formed in the door 14 is inserted and guided. The doors 16 and 16 'to which the toe guard 17 is fixed are inserted and guided to the 14a, and the toe guard 17 is fixed to the vertical portion 14b formed in the door 14. In the door threshold autonomous of an elevator, the boarding point 11 is attached to the board | substrate 14 fixed by the stud bolt 18, 18 'and the nut 19, 19' which are embedded in the upper end of both sides of the said building 13. A horizontal portion (14c) forming the same plane as the (), the horizontal guide groove (14a) is formed in the vertical portion (14b) of the door 14, the sliding door (15), (15 ') Several bent L-shaped at the lower end of Fixing between the support 20, 20 ', the lower end of the support 20, 20' is inserted into the guide groove (14a) of the door 14, the door leg 16, (16 ') is fixed.

The door lock device of the elevator platform according to the present invention, configured as described above, the door lock 14 on the stud bolts 18, 18 'placed on both sides of the building 13 of the platform 11, the nut 19, (19 ') and fixed to the support grooves (20) and (20') of the sliding doors (15) and (15 ') in the guide groove (14a) formed in the vertical portion (14b) of the door (14). The assembly is completed by inserting the doors 16 and 16 ', and the sliding doors 15 and 15' are linked to the sliding doors of the elevator as in the conventional case, and the opening and closing operation is performed.

As described above, in the door sills 14 according to the present invention, the guide grooves 14a through which the doors 16 and 16 'of the sliding doors 12 and 15' are guided to the vertical portion 14a. Since it is formed in the direction can prevent the accumulation of dust in the guide groove (14a), and prevents the phenomenon that vibrates violently by the guide groove (14a) of the door 14 even when the movable body with wheels, such as wheelchairs are moved It is possible to prevent damage to the guide groove 8a (see FIG. 2) as in the conventional case. In addition, in the manufacturing process of the door sills 14, the shape of the door sills 14 is considerably simplified compared with the conventional art, and there is an advantage in that it is easy to manufacture. As the conventional door 13 is used, the building 13 It is not necessary to form a separate support part 6 (see FIG. 2) in the c), and it is not necessary to use a separate concrete for fixing the door 14 so that the installation process of the door 14 becomes easier. There are several effects.
