That is, in the present invention, the guide rails 11A and 11B of the frame 10 are installed by fixing the reinforcement angle 34 to the rear of the guide rails 11A and 11B by utilizing the rear bottom surface 15. When the up door 20, in particular, the guide member 24 of the lower door 22 is detached and the lower door itself is pushed backward while being bent or damaged, the departure prevention part 34A of the reinforcement angle 34 By being configured to support, it was to prevent the fall of the up door 20, including the lower door.

Since the rear bottom surface 15 of the doorway is a seat where the wheel of the vehicle passes in the width direction, as shown in FIG. 1, the reinforcement angle 34 is the rear bottom surface of the guide rails 11A and 11B. It is preferably fixed to (15), it is fixed so as not to protrude more than a predetermined width in the inward direction of the doorway (D).

The reinforcement angle 34 has a bottom engaging portion 33A connected to the release preventing portion 34A to be fixed to the bottom surface 15, as shown in the lower right circle perspective of FIG. It is preferable to allow the anchor bolt to be fixed to the rear bottom surface 15 by penetrating the coupling hole 34b of the portion 33A so as to secure a supporting force when the updoor 20 is detached.

At this time, the reinforcement angle 34 is provided to be spaced apart from the left and right frame 10 provided with the guide rails (11A) (11B) at a predetermined distance to the rear door 22 so that the impact of the lower door 22 is partially solved. It is possible to more smoothly prevent the departure of the lower door 22 through securing the bearing capacity.

Next, since the upper door 21 and the lower door 22 are arranged at the front and rear, respectively, and are coupled to the guide rails 11A and 11B of the frame 10, the upper door 21 is eventually Departure can be said to be more stable through the fastening force between the frame (10).

That is, in view of the fact that the impact occurs in the center of the width direction of the up-door 20, the separation of the up-door 20 is prevented through the fastening force with both frame 10, the horizontal frame 10, that is, the upper side It is more effective to resist the impact through the clamping force with the mold (13).

Therefore, the present invention is to prevent the fall in the hoistway (P) direction by the engagement with the upper frame 13 of the frame 10 when the up door 20 is impacted from the front.

As the separation preventing means 30, the upper end portion 21a of the upper door 21 and the upper frame 15 of the frame 10 are spaced apart from each other, as shown in an enlarged side view of the left and right sides of FIG. 3. The first contact portion 21S (refer to FIG. 1) and

The upper end portion 22a of the lower door 22 and the lower end portion 21b of the upper door 21 are provided at each of the second contact portions 22S (see FIG. 1) that are spaced apart from each other.

Upper ends 21a and 22a of the upper door 21 and the lower door 22 are respectively disposed on the upper frame 15 of the frame 10 and the lower end 21b of the upper door 21. It characterized in that it comprises a departure prevention cover 35 to be restrained.

Some and the second constraining part 35B are fixed to the upper and rear surfaces of the upper end portion 21a of the upper door 21 by welding or the like.

Therefore, when the upper door 21 is lowered and lowered through the clearance S1 between the first constraining part 35A and the bent part 13a, the inner surface of the first constraining part 35A and the bent part 13a are separated. Since no contact with the outer surface occurs, no noise is caused by rising and falling,

When the impact is applied from the front of the upper door 21 and the upper door 21 is pushed backward, the impact is canceled by the distance of the free space S1, and then the first constraining part 35A is the bent part 13a. By restraining and supporting the upper door 21 so that the upper door 21 is no longer pushed backward while being in contact with the upper door 21, the detachment and the fall of the upper door 21 can be prevented.

In addition, the separation prevention cover 35 provided in the second contact portion 22S is also made of the above configuration,

When the lower door 22 is pushed backward by providing the first constraining part 35A and the locking part 21c of the lower end 21b of the upper door 21 at a predetermined interval S2, the lower door 22 is pushed backward. Through the process, the lower door 22 is constrained to the upper door 21 to prevent departure,

Therefore, the up door 20 is eventually restrained and supported by the upper frame 15 of the frame 10, thereby preventing the up door 20 from escaping to the hoistway P.

By doing so, it is more preferable to partially assist the function of the door detachment preventing means through the structure in which the buffer member 26 is fitted in the slit groove.

The buffer member 26 and the slit groove are provided at positions adjacent to both ends of the frame 10, that is, the guide rails 11A and 11B, or spaced apart at predetermined intervals along the width direction of the bottom surface of the doorway. It may be provided.

Next, as all buildings are required to install a firewall, etc. to prevent the spread of fire in the event of a fire, the necessity of preventing fire spread is on the rise.

In particular, when a fire occurs in the lower floor of the building, smoke or flame spreads very quickly through the elevator's hoistway (P). Therefore, various means are provided to prevent this, and when the elevator is installed, the fire diffusion prevention test is essential. Considering that only a company can install elevators, fire spreading prevention means is one of the most important components.

Therefore, the elevator of the present invention also uses the material of the up door 20 as a fire resistant steel material to prevent fire spreading, but even in this case, through the gap generated between the up door 20 and the frame 10. It is important to prevent the spread of flames, in particular the spread of smoke, to provide a safer lift.

Therefore, the present invention is a fire spreading prevention means to prevent the smoke or flame does not flow into the hoistway (P) or the doorway (D) in front of the space through the gap formed between the lower door 22 and the bottom surface of the entrance when the fire occurs. It further comprises.
