[0003] It is necessary to be able to manually open the door from the outside so that the passengers of each passenger car can immediately be released and leave the area in an emergency or emergency, particularly in the event of an accident or fire. For this purpose, it is well known that a device for controlling unlocking of the door from the outside is provided. These devices are provided with mechanical means suitable for moving the locking mechanism, such as a handle for activating the cable, to unlock each door and allow the door to be moved by hand. I have.

[0004] However, these mechanical means are often not easy to use quickly due to their large number, and sometimes have considerable physical implications, especially when controlling the unlocking of multiple doors. Power is required, and the safety rules imposed on passenger trains are becoming increasingly strict.

[0005] Applicants have therefore unlocked all the doors on the same side of the coach from both the outside and the inside simultaneously, allowing them to be operated by hand, yet still causing the full opening of each door. In doing so, he learned that there were new rules imposed on building emergency devices that would not cause the passengers leaning on the door to pop out. A mechanism that mechanically drives all of the doors requires a force that cannot be exerted by human operating force.

[0006]

Therefore, when electric means is available, an emergency device must be designed using electric energy provided in the train. It is an object of the present invention to overcome these disadvantages by proposing an emergency device which can be activated very easily by a person outside the vehicle and which can unlock one or more doors immediately. It is an object of the present invention to provide a solution to the above problem.

[0007]

According to the invention, the emergency device is provided on an external surface of the vehicle for transmitting a first electrical signal at the time of activation of the device, and is electrically connected to the electromechanical control mechanism. And a means suitable for receiving the first electrical signal sent from the switch and generating a predetermined current pulse to cause a reliable unlocking operation of each movable part. It is configured as an emergency device characterized by having the following. Therefore, one or more doors can be unlocked immediately by simply operating the switch. Since this unlocking operation is controlled electrically, it can be instantaneously performed by all persons regardless of human power. For example, the device can be arranged so that when a single switch is activated, all the doors on one side of the carriage are unlocked. In addition, this emergency device does not reduce the operational reliability or safety level of the electromechanical mechanism of the door at all.

[0009] It is also possible to install the same device inside a vehicle. According to a preferred embodiment of the invention, the switch activates, by means of the first electrical signal, a control element for controlling each movable part and possibly a motor for driving a corresponding locking or locking mechanism. Connected to the control mechanism. Further, the emergency device may include contact means suitable for transmitting the second electric signal when the electric motor is rotated by a predetermined angle. The predetermined angle can be selected so that the door can be unlocked immediately upon rotation of the motor by this angle. The contact means is arranged, for example, on a motor or a control element.

According to a preferred embodiment, these contacting means are connected to a control mechanism such that the motor is immediately stopped by a second electrical signal. At this time, the movable portion is opened without causing the electric motor to be a danger source, so that the movable portion can be operated immediately. According to another preferred embodiment of the present invention, the predetermined angles described above are selected to induce a secure unlocking of each movable part and a slight opening action. Thus, even if the surface configuration of each movable part has little clues that can be operated for manual opening, the movable part slightly forms an open space, and the hand is inserted into the open space. And a force substantially parallel to the surface of the movable part can be applied without difficulty. This slight opening also completely eliminates the danger of leaning passengers leaning out and jumping out.

The emergency device may further comprise mechanical means suitable for reliably moving the locking mechanism in response to inducing the unlocking of each movable part. These mechanical means may be conventional means and may constitute a second emergency means in the event that the power supply and the means of the present invention fail.

Needless to say.

[0012]

In this embodiment, the emergency device according to the present invention is applied to a single door having two movable parts of a railway carriage for transporting passengers. Referring to FIG.
The sliding door 1 illustrated in a closed state is a doorway 2 on a guideway 3.
Movable parts 1a and 1b suspended through
It has. The open state is indicated by a dashed line.

The door 1 is connected to an electromechanical mechanism for controlling the closing and locking or unlocking and opening of the movable part. That is, the screw 4 cooperates with the nut 5 having the protruding portion 6 housed in the slider 7 parallel thereto. This nut is kept in a non-rotating state and can only translate along the axis of the screw 4. Each nut is housed in a fork member 8 which is integrally connected to one of the movable parts, so that the translational movement of the nut 5 is transmitted to the movable parts. Near the end of the movement of the nut 5, a lateral space, not shown, is provided in the slider 7, so that under the action of the screw 4 the projecting part 6 is received in that space. I am getting it. From the time of reception, the door movable part is immobilized and cannot be unlocked except by turning the screw in the opposite direction to pull out the protruding part 6 from the cavity.

The screw 4 is rotationally driven by an electric motor 11 connected via a belt type power transmission. Such electromechanical mechanisms for activating moving parts are well known and will not be described in detail here. The door 1 is provided with an emergency device for externally controlling the positive unlocking of the door in the closed position from the outside. The device classically comprises mechanical means suitable for reliably moving the corresponding locking mechanism so as to induce the unlocking of each movable part 1a and 1b. The screw 4 also has two disks 12a and 1 integrated with the screw in its rotational movement.
2b. Each of these disks has a cable 13 fixed to the disks 12a and 12b around its periphery.
a, 13b has one annular groove around which it is wound.

In order to mechanically unlock the two movable parts 1a and 1b, the two handles 14a and 14b are used to pull out the protruding part 6 from the above-mentioned space so that the discs 12a and 12b are pulled out.
b and each screw 13 to rotate the screw 4.
A tensile force can be applied to each of a and 13b. Handles 14a and 14b are located outside and inside the vehicle, respectively. Such mechanical unlocking means are also known.

According to the invention, the emergency device comprises a switch 15 provided on the external surface of the vehicle. Referring to FIG. 2, the switch 15 is electrically connected to the control device 16 of the electric motor 11 to emit a first electric signal when activated. The control device 16 is conventionally known. Similarly, the control device receives the first electric signal transmitted from the switch 15 and
And means suitable for generating an electrical pulse for rotating the motor 11 by a predetermined angle to cause the positive unlocking of 1b and 1b. In this example, the switch 15 is connected to the control mechanism 16 in such a way that the first electrical signal triggers the start of the motor 11.

The activation of the switch thus triggers the start of rotation of the screw 4 and the unlocking of the movable parts 1a and 1b. The emergency device comprises contact means 17 adapted to emit a second electric signal when the electric motor 11 rotates by the predetermined angle. These means are conventionally known and applied and include, for example, on the electric motor 11 or on the screw 4 and also an angular position detector mounted on one of the movable parts. The contact means 17 is connected to the control device 16 so that the second electric signal controls the instantaneous stop of the motor 11. The predetermined angle is selected so as to induce a positive unlocking and a small amount of opening of each movable part 1a, 1b. Thus, the actuation of the switch 15 induces the unlocking of each of the movable parts 1a, 1b and, for example, a separating operation so as to set a space of 5 cm therebetween. At this time, the door can be completely opened by operating both movable parts without difficulty by inserting a finger into this space.

The switch 15 is electrically connected to these doors in a similar manner by wires 18 so as to enable the unlocking and partial opening of all other doors on the same side of the carriage as a whole. It can also be connected. Naturally, the same switch to unlock and semi-open at the same time,
It is also possible to connect more doors. Another switch 1 similar to switch 15 inside the passenger car
It is also possible to arrange 9. This switch 19 will be arranged to trigger the unlocking and full opening of the passenger car door, for example, to facilitate its maintenance and maintenance or to allow emergency passengers to escape.

Naturally, without departing from the scope of the invention, the invention can be modified by replacing some of the above-mentioned mechanisms, in particular screws 4 etc., with equivalent means, for example belts or chains. Various changes and improvements can be made. Thus, for each movable part, the electric motor 11 driving the control element (screw) 4 of this part and the second activation electric mechanism 2 of the corresponding unlocking mechanism
0 is provided in the electrical mechanism;
Suitable means for receiving the electrical signal of the motor may generate a pulse for inducing a secure unlocking of the locking mechanism and a pulse for rotating the electric motor 11.

As described above, the second starting electric mechanism 20
May be any suitable known electromagnet suitable for moving the locking mechanism. In this case, it is also important to rotate the electric motor 11 in order to prohibit relocking of the movable part. Handles 14a and 14b may be used to unlock the movable parts of adjacent doors in a manner that requires only the human resources possible of any human being and proposes one solution which is acceptable from the above rules. , The second cable passing through the duct 21 can be activated.

Depending on whether one wishes to control the same operation with the switches 15 and 19, the connection 22 in FIG.
Or 23 can be deleted. The switches 15 and 19 can of course also be installed in parallel in a cab or in a train cabin with similar switches which can open part or all of the train door.

[0022]

From the above, it can be understood that, when the lock mechanism is released, the movable portion of the door can be easily separated by hand by rotating the screw 4 and the electric motor 11 idle. The device, of course, provides a means for overriding the normal functioning control of one door when an electrical unlocking emergency command for the door is transmitted by one of the switches 15, 19 or the like. Have. At the time when the electric unlocking command of the door is canceled, the means of the device according to the invention provide the function of the electric motor 11 to lock the corresponding door or doors or open these doors on the contrary. Of course can be adapted to control For this reason, the switches 15, 19 are of the type in which, in order to cancel the preceding unlocking command, for example by an authorized person with an unlocking tool, the switch remains in the starting position until it is manually returned to the normal standby position. May be something.
