Referring to this, the auxiliary safety door opening and closing device 100 of the elevator according to an embodiment of the present invention, when the elevator car does not reach the floor, the landing door is opened due to an electronic error or external physical force Even if the landing door is damaged and the space is opened, the auxiliary safety door located inside the elevator car is not opened until the elevator car reaches the floor, thereby preventing the occupant's safety accident.

To this end, the auxiliary safety door opening and closing device 100 of the elevator according to an embodiment of the present invention is provided between the elevator passage 6 and the landing door 8 is configured to open and close, the elevator passage (6) The auxiliary safety door 200 is provided with a plurality of locking brackets 204 and 208 spaced apart from each other in the front predetermined direction.

In addition, the auxiliary safety door opening and closing device 100 of the elevator according to an embodiment of the present invention is formed on the rear predetermined portion of the elevator door 104, is coupled between the engaging brackets (204, 208) when the auxiliary safety door when opening and closing Engaging protrusions 106 and 108 for opening and closing the 200 together are configured.

That is, the auxiliary safety door 200 is configured to be able to slide open and close between the elevator passage 6 and the landing door 8, the front predetermined portion is provided with a plurality of engaging brackets (204, 208), respectively. Bars, preferably, two or more locking brackets 204 and 208 are installed in a pair of at least one pair in front of both side doors of the auxiliary safety door 200.

The locking brackets 204 and 208 protrude toward the front of the door, and a plurality of the locking brackets 204 and 208 are spaced at regular intervals so that an insertion portion 206 is formed between any one of the locking brackets 204 and the adjacent locking brackets 204. The engaging protrusions 106 and 108 are coupled to the insertion portion 206.

Therefore, when the elevator car 102 moves to each floor, the locking protrusions 106 and 108 formed on the elevator car 102 pass through the locking brackets 204 and 208 of the auxiliary safety door 200 provided on each floor. When stopping at the floor to be stopped, the engaging protrusions 106 and 108 formed in the elevator car 102 are coupled to the internal insertion portion 206 of the engaging brackets 204 and 208 of the auxiliary safety door 200 provided at the corresponding floor. Will be.

That is, the locking brackets 204 and 208 and the locking protrusions 106 and 108 are respectively installed at positions that are automatically coupled to each other when the elevator car 102 is stopped.

In addition, the auxiliary safety door 200 is coupled to a plurality of movable rods 210 on the upper and lower surfaces of the door body 202, the movable rod 210 is a support bracket 212 fixed to the wall (4) Is coupled to the slide moveable.

Preferably, since the moving rod 210 is provided with a ball bearing (not shown), the auxiliary safety door 200 is configured to be easily opened and closed in synchronization with opening and closing of the elevator door 104.

Figure 5 is an enlarged front view showing the main portion showing the structure of the locking bracket included in the auxiliary safety door opening and closing device of the elevator according to an embodiment of the present invention.

Referring to this, the engaging brackets (204, 208) included in the auxiliary safety door opening and closing device of the elevator according to an embodiment of the elevator door 104 is bent the inlet portion 209 of the upper and lower ends in the outward direction The engaging projections 106 and 108 formed in the are configured to be easily inserted.

That is, while the elevator car 102 moves to the platform of each floor, the locking protrusions 106 and 108 formed in the elevator door 104 pass through the locking brackets 204 and 208, or the locking brackets 204 and 208. In order to easily engage the engaging projections 106 and 108 with respect to the engaging brackets 204 and 208, the engaging brackets 204 and 208 are bent outwardly at their inlets 209 at the upper and lower ends thereof. It was made possible.

With reference to the accompanying drawings, the function and action of the auxiliary safety door opening and closing device of the elevator according to an embodiment of the present invention of the above configuration will be described in detail.

In the auxiliary safety door opening and closing device 100 of an elevator according to an embodiment of the present invention, when the elevator car 102 moves to each floor, the locking protrusions 106 and 108 formed on the elevator car 102 are provided on each floor. When passing through the locking brackets 204 and 208 of the auxiliary safety door 200, and when stopping at the corresponding floor to stop, the locking projections 106 and 108 formed in the elevator car 102 are provided as auxiliary safety provided on the floor. It is coupled to the internal insertion portion 206 of the locking brackets 204 and 208 of the door 200.

Therefore, when the elevator car 102 stops on a specific floor to get on and off the passengers, the elevator door 104 is opened at the same time in conjunction with the landing door (8).
