The present invention relates to an elevator room door apparatus. In general, there are no locking devices in the doors of elevator rooms.

For this reason, when the elevator is running, the door of the elevator room, which is fully closed, is operated in the closing door direction by the drive motor and held in the fully closed position.

However, when an abnormality occurs in the elevator and the safety device operates, the elevator control system including the drive motor of the door is cut off when the elevator room is emergency stopped.

In this case, since the operation of the closing door direction is blocked, the passenger in the elevator room opens the door of the elevator. On the other hand, in the middle of an elevator stop, there is usually a gap of 15-20 cm between the elevator and the wall of the hoistway, so when the passengers in the elevator door open the elevator room when the elevator cabins make emergency stops outside the platform, that is, outside the normal stop section, There is a risk of falling into the hoistway in the above gap.

The cam of the engaging device 8 with a gear, 100 is an engaging body of the engaging device 8, and 10a is a first link supported by a shaft 10b fixed to the elevator room 1, 10c. Ring 1 A pin fixed to one end of the rack 10a, 10d is a pin fixed to the elevator room 1, 10e is a tension coil spring coupled to both ends of the pin 10c and the pin 10d, respectively (10f). ) Is a shaft fixed to the other end of the first link (10a), (10g) supports the roller (10k) by a shaft (10h) provided at one end, the second link having an extension (10j) at the other end, 10k indicates that the lateral formation is L ground, and is supported by the first link 10a, and the L-shaped longitudinal tip 10m forms a cross-sectional sphere so as to surround the second link 10g from the side. Moreover, this two-way part is widely formed to the outside.

The pin 10p is fixed to the L-shaped transverse end 10n of the holding device 10k.

10q is a tension coil spring, one end of which is hung on pin 10p and the other end of pin 10r fixed to first link 10a.

10l is a shaft installed in the first link 10a and fixed between the shaft 10b and the shaft 10f, 11 is an interlocking device of the engaging device 8, and 11a is an elevator room 1 The third link (11c) supported by the shaft (11b) fixed to the (), the roller supported by the shaft (11b) fixed to one end of the third link (11a), (11d) is the third link, (11a) The shaft 11f fixed to the other end of is a connecting rod, one end of which is supported by the shaft 10s and the other end of which is supported by the shaft 11e.

Denoted at 12 is a closed release device, 13 is a first operator arranged at a recess in the elevator room 1, 13b is L-shaped, and is outside the elevator 1 The second operator 14, which is arranged, is an axis penetrating out of the elevator room 1 in the elevator room 1, and is supported by the elevator room 1, and both terminals of the first and second operators 13a, (( 13b) is stuck.

(15) is an operating device composed of a well-known rolling element mainly composed of a tubular flexible body and wires inserted therein, one end of which is at the tip of the L-shape of the second operator 13b. The other end is fixed to the pin 10p of the holding device 10k.

(16) is a stopper consisting of a cam fixed to the hoisting wall (17) disposed at a spaced distance (G) from the retracted roller (11c), the entrance (2) to the elevator platform (not shown) When the elevator room 1 stops at a position not corresponding, that is, when the elevator room 1 stops outside the normal stop section, it is provided so as to face the roller 11c regardless of its position. In other words, the second link 10g of the engaging device 8 is held at a predetermined position by the holding device 10k at a normal time relative to the first link 10a.

Thus, the second link 10g is operated clockwise in FIG. 1 by the tension coil spring 10e. By the way, when the elevator door 3 is in the fully closed position as shown in FIG. 1, the roller 10i will contact the inclined surface 9a of the cam 9, and the roller 11c will be hold | maintained in a retracted position.

In this state, the elevator room 1 is moved up and down, but since the space | interval G is provided between the roller 11c and the stopper 16, a transferee does not contact each other. When the elevator compartment 1 stops within the normal stop section and the elevator compartment door 3 is opened by the drive device 4, the elevator compartment door 3 moves against the pressing force of the roller 10i. It is in the state shown in 2 degree, the roller 10i displaces and moves the flat end surface 9b of the cam 9, and the roller 10i is supported by the flat surface 9b even if the elevator door 3 is fully closed. It is. At this time, the third link 11a rotates counterclockwise in FIG. 2 through the connecting rod 11f, and the roller 11c protrudes.

In addition, when the elevator room 1 stops abnormally outside the normal stop section and the passenger manually opens the elevator door 3, the roller 10i causes the roller 9i to be inclined 9a of the cam 9 by the opening operation of the elevator door 3. Start to displace through However, the roller 11c is displaced to the protruding position by the start of displacement of the roller 10i. When the distance G is moved, the protruding operation is brought into contact with the stopping body 16 and shown in FIG. This is stopped.

Thus, the displacement of the roller 10i is also prevented at the same time as the support of the roller 11c is protruded, and the movement of the cam 9 to the flat surface 9b is restrained.

Because of this, the opening operation of the elevator door 3 is prevented, so when the elevator room 1 stops abnormally, it is possible to prevent the accident that the passenger falls on the hoistway.

Moreover, the opening dimension R of the elevator door 3 is several centimeters or less while the roller 11c moves the space | interval G in a retreat position. In addition, if the abnormal stop position of the elevator room 1 is within the normal stop section, since the stopping body 16 is not arranged, the passenger can manually open the elevator room door 3 and can safely escape from the platform. In addition, when the elevator room 1 stops outside the normal stop section, the first and second operators 13a and 13b of the closing release device 12 are opened when the elevator door 3 is opened due to the necessity of additional work. Either of which is operated in the direction in which the actuator 15 is tensioned.

By this operation, the retainer 10k is rotated counterclockwise in FIG. 5 against the tension coil spring 10q.

Accordingly, the holding of the second link 10g by the first link 10a is released, and the latter can rotate counterclockwise with respect to the former in FIG. 3 by the opening operation of the elevator door 3. do.

Therefore, the elevator door 3 can be opened inside and outside the elevator room 1 even when the protrusion of the roller 11c is prevented by the blocking body 16. Moreover, when the 1st operator 13a is arrange | positioned at the high place in the elevator room 1, play of a child can be prevented. In addition, when the elevator 1 abnormally stops at a position where a few centimeters of the up and down ends of the entrance and exit 2 and the lifting entrance and exit (not shown) face each other, even if the stopper 16 is disposed at the position, a fire may occur. Even when an emergency condition such as an occurrence occurs, a passenger in the elevator room 1 can operate the first operator 13a to open the elevator room door 3 and escape.

In addition, when such an elevator room 1 stops abnormally, the rescuer outside the elevator can operate the second operation site 13b at the platform to close the door and rescue the passengers. Furthermore, it is also preferable to display the precautions of the operation near the first operator 13a. Moreover, it is also preferable to provide the 2nd operator 13b in the upper and lower edges of the elevator room 1, respectively. It is also preferable to provide the second operator 13b near the upper and lower ends of the elevator room 1, respectively.

As described above, the present invention is provided with an engagement device that engages a fully closed elevator door and displaces it to a retractable position by its opening operation, and an engagement device that is installed in an elevator path that prevents this displacement and that is operated in an elevator room. A closing device for displacing the door, and when the stopper stops outside the normal stop section of the elevator room, the door of the elevator door becomes inaccessible, and the door of the door that cannot be opened is required by operation of the operation of the closing device. When it is possible to open.

Therefore, when the elevator room stops abnormally, if it is in the normal stop section, it is possible to open by the passenger early, and if it is outside the normal stop section, it is impossible to open by the passenger and prevent the fall accident in advance. You can do it.

In addition, if necessary by the closing release device, the elevator door can be opened even if the elevator room stops outside the normal stop section, and maintenance work is possible.
