Description

Emergency exit door locker {Emergency exit door locker}

The present invention relates to a door lock device, and more particularly, to an emergency door lock device for satisfying a security function and an emergency function at the same time by making it difficult to open the emergency door normally installed for evacuation in an emergency.

In general, when operating residential, commercial or business buildings, security systems are in place to protect people and property from outside intruders. The security system installed in the building not only blocks outside intruders, but also detects fires in the building.

On the other hand, if a fire occurs in a building, the insider should be able to quickly escape the building and move to a safe place. Evacuation from a fire is the act of escaping from the inside of the building to the rooftop or outside the building.

In the room, general smoke flow and diffusion proceeds along walls or ceilings, and in the presence of shafts such as stairs or vents (ducts), the chimney effect causes rapid conflict and contaminates the upper system. Smoke flow and diffusion in low-rise buildings cause smoke flow such as heat, convection, and fire pressure generated by the man itself.

The main causes of smoke flow in high-rise buildings are as follows.

① Expansion of combustion gas (smoke) by temperature

② Stack Effect

③ Wind Effect

④ Mechanical air distribution in the building

However, in accordance with crime prevention, environmental management problems, personal interests, etc., the emergency door is locked and the majority of them are left with serious severity and safety insensitivity, and in case of emergency, they often lose their lives or get injured. .

Emergency doors are installed in most buildings, and many performance halls, restaurants, nightlife, offices, and apartments are required to establish emergency exits. Emergency doors installed for the opening and closing of emergency exits shall be open for internal access at any time. The main function of emergency doors is to ensure escape in the event of a fire, but security functions must also be satisfied. In general, an appropriate locking device is attached to the emergency door so that it can be opened and closed freely from the inside without opening and closing from the outside.

However, there are many cases in which emergency doors are locked so that they cannot be opened or closed inside because of lack of awareness of fire or other reasons. In the case of apartments, emergency doors to the roof are locked to prevent the rooftop from being used as a youth derailment or crime place.In the case of entertainment and restaurants, it prevents customers from escaping without calculating the service fee, The emergency door may be locked internally for control.

It is also very dangerous to put a lock on the emergency door. Fires quickly bring fatal danger to many people, and those who are at risk are often embarrassed and embarrassed. In the event of a fire, it is not easy to find the key and open the emergency door, so it may be necessary to destroy the lock with a blunt tool and open the door.

On the other hand, if an emergency door is left open to anyone, it may not be possible to achieve sufficient security functions internally or externally. As described above, if the emergency door is left in a state that can be easily opened and closed from inside, the security function will not be sufficiently achieved.

The present invention was created to solve the above conventional problems, the object of the present invention can not be opened from the outside but can be opened by operating the piston handle inside, the door by operating the piston handle in the state without releasing the safety device When opening the door is to provide an emergency door lock device that makes it difficult for the operator to open and close the emergency door to give an unpleasant feeling to the operator while operating the alarm device.

Emergency door locking device of the present invention for achieving the above object, and a piston having an electrode; A cylinder part providing a path in which the piston part is moved back and forth, the cylinder part having an electrode which is brought into contact with the electrode of the piston part when the piston part is moved to a predetermined position; It is characterized by including the enclosure which protects the said cylinder part from an external shock.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows the operating state of the emergency door lock according to an embodiment of the present invention, Figure 2 is a detailed view of the cylinder portion.

According to Fig. 1, this embodiment includes a piston part, a cylinder part, and a housing part.

The piston part includes a piston 120 which is moved back and forth with respect to the cylinder part, a piston handle 121 provided to easily move the piston 120, and an electrode 123 made of a conductive member.

The cylinder part is a cylinder 140 which is a passage through which the piston 120 moves, an air outlet 141 for allowing air to flow into the cylinder 140 when the piston 120 is moved in the cylinder 140, and a cylinder. Rubber packing 142, which provides a frictional force when the piston 120 is moved within 140, an electrode 148 of a conductive member.

The housing part includes a housing 130 containing the cylinder 140, a lock ring 151 for blocking the opening of the housing 130, and a lock 150 for locking the lock ring.

If the lock is to be mounted and operated on the emergency door 20, appropriate support means are required. In this case, the lock 130 of the locking device is mounted on the emergency door 20 and supported using the fixing support 112 and the fixing bolt 111, and the opposite side of the piston 120 is fixed support mounted to the wall surface 10 Support 112 and the fixing bolt 111.

Since the piston handle 121 is a rotational movement, the piston 120 can be moved by manipulating the piston handle 121 with one or both hands in a horizontal or vertical position in a comfortable posture.

This lock allows for quick evacuation in the event of a fire, while preventing children and teenagers from entering the rooftop and opening and closing the lock without damaging the lock if necessary. Emergency door 20 with a lock can not be opened from the outside but can be opened from the inside. However, in order to open the emergency door 20 by operating the locking device inside, only the designated stabilizer should be released. If the emergency door 20 is operated without releasing the safety device, the alarm device is activated.

In addition, it has a locking effect that satisfies external intrusions, environmental management problems, and personal interests. Among human instincts, there are homing instincts, avoiding instincts, cognitive instincts, left instincts, and following instincts. Of these, the instincts of avoidance and following instincts are particularly effective.

This is because safety zones for evacuation or firefighting activities should be fixed from the place of fire to fix safety zones such as the first, second, and third places to avoid flames and smoke, and evacuation stairs, etc. This is because it is necessary to secure copper lines and evacuation routes with multi-directional copper lines so that they can be properly responded to a fire or fully behave in a psychological panic (or panic).

To satisfy this requirement, the lock is opened and closed with a simple, clear and simple manpower without any power. In other words, the locking device is fixed to the forward and backward way, the magnetic force between the magnets and the friction force of the rubber packing 142, the piston handle 121 is reversed to open the door, depending on the building type, floor area, environmental conditions, automated material detection equipment (transmitter, P-type receiver, R-type receiver, alarm or repeater) or alarm device. Therefore, when the electrode 123 provided in the piston 120 and the electrode 148 provided in the cylinder 140 are in contact with each other and energized by the operation of the piston 120, the alarm device is activated to open the emergency door 20. You will know. Here, the electrode 148 provided in the cylinder 140 is processed into a coil spring using an elastic member, and the elastic force is maintained at a predetermined level.

When the emergency door 20 is opened, the automated material detection device installed to receive an electric signal from the lock as the electrode is energized is determined to be a fire, and if an alarm is sounded but the fire is not a fire, the operator or security guard is on site. You can then take appropriate action.

Normally, the emergency door 20 should not be opened arbitrarily from the inside, which is realized in a manner that is offensive to the person who arbitrarily manipulates the locking device. Due to the operation of the piston 120 of the locking device is installed when the interelectrode energization is made to install a high tank around the locking device to spray water or generate an unpleasant smell.

3, a high tank is illustrated.

According to FIG. 3, the high tank 310 includes a water tank 314 containing water, a bad smell container 311 containing a substance causing odor, a cover 320 covering the water container 314 and the bad smell container 311. The solenoid valves 312 and 313 allow the odor and water to be discharged into the atmosphere when the electrodes 120 and 148 are energized due to the operation of the piston 120 of the locking device.

In some cases, the water supply tank 330 is further provided to supply water when the water level of the water tank is lowered. In the case of using the water supply container 330, the manual valve 331, the bowl tab 316, and the burette 317 are further placed in order to control the water level of the water container 314. When supplying water to the bucket 314, the manual valve 331 may be operated. However, considering the winter season, water and antifreeze may be mixed and used, and the whole high tank may be made of a heat insulating member to prevent water from freezing. .

In addition, the siphon 315 may be placed or the water supply container 330 may be placed at a high position to open the solenoid valves 312 and 313 so that the water is continuously discharged when the water is discharged from the bucket 314. . By using the water supply container 330 and the siphon 315 to continuously discharge the water there is an effect of extinguishing or progressing the fire around the locking device. To further enhance this effect, it is possible to replace the odorous substance in the odor bottle or to include a powdery non-combustible substance with the substance to sufficiently prevent the progress of fire near the emergency door.

In addition, when the water is introduced into the sealed bucket, and in other cases, the pneumatic valve 321, 322 implemented as a bicycle or car air inlet to the cover to adjust the air pressure in the high tank 310, Put it. In order to increase the air pressure in the high tank 310, the high pressure air may be press-fitted through the air pressure valves 321 and 322, and the compressor 323 may be used to effectively maintain the air pressure at a predetermined level. Water is air sprayed by the opening of the solenoid valves 312 and 313, and when the water is immersed in the water tank 314 through sequence control and computer control, high pressure air is generated in the compressor to maintain a constant air pressure.

The man who operated the locking device to open the emergency door 20 feels unpleasant when the unpleasant odor and the water is discharged and backs off. This makes a strong impression on the operator, and the experienced person later avoids attempting to manipulate the emergency door 20. By appropriately adjusting the time point at which the electrodes 123 and 148 become energized, the operator may feel discomfort when the piston 120 does not fully open the emergency door 20.

In some cases, by adding a pigment to the water can further strengthen the sense of alertness, using food coloring harmless to the human body. In addition, by giving a constant air pressure to the bad smell tank (311) and the water tank (314) so that the discharged material when the solenoid valve (312) (313) is opened can be strongly sprayed into the air, the position to operate the piston handle 121 Consideration may be given to the application of the substance to specific areas of the body.

In this way, the locking device is normally operated to prevent opening of the emergency door 20.

However, in the event of a fire or other emergency, in order to protect their lives, despite the temporary discomfort, the piston 120 may be fully retracted to open the emergency door 20. The emergency door 20 will be able to fully open in an emergency situation.

In addition, an electronic detection sensor and an alarm device may be attached to the locking device. FIG. 4 shows devices interlocked with an emergency door locking device according to an embodiment of the present invention, and is operated when the electrodes 123 and 148 are energized. Electric fan 410 to discharge the smoke or smell to the brain, the human body sensor 420 to detect when a person is close, smoke detection sensor 430 to detect the occurrence of smoke, electrodes 123 (148) Warning broadcast equipment 440, which alerts the operator of the locking device or the person in close proximity to the alarm when the current is energized to cause an alarm to the person close to the emergency door when the electrode 123 (148) is energized Warning lamp 450 and the like to emit light can be linked to the locking device. The electric fan 410 or the warning broadcast equipment 440, the warning lamp 450 is not only when the electrodes 123 and 148 are energized, but also the human body sensor 420 or the smoke sensor 430 detects the detection signal. When the youth comes close to the emergency door, the human body detection sensor 420 detects the human body and the warning broadcast device 440 and the warning lamp 450 is operated to operate the pistons with mischief or carelessness. Prevent the possibility of odor emissions. By sounding an alarm when approaching an emergency door, you not only alert the person but also give them the opportunity to escape unforeseen contamination. The human body detecting sensor 420 is capable of operating at a close distance using a semiconductor device such as a photodiode / phototransistor and detecting the amount of light, or implemented as an ultrasonic sensor, a CDS sensor, or the like. Detects the presence or absence of light and brightness and converts it into an electrical signal. When the alarm device is activated due to the detection of the detection sensor, depending on the selection, only the warning broadcast device 440 or the warning lamp 450 may be operated or the high tank may be operated and an alarm may be sounded to the security system.

On the other hand, by using a friction force between the fixed support 112 and the piston 120 to prevent the emergency door 20 from being opened from strong winds or vibrations. In a further improved manner, the rubber packing 142 is attached to the end 122 of the piston, and the magnet 143 or iron is attached to a part of the rubber packing 142, and the magnet 143 is locked. Another magnet 144 is fixedly adhered to the surface of the cylinder 140 opposite to). In the latter method, the attraction between the magnets 143 and 144 in the locked state prevents the rubber packing 142 from flowing, thereby preventing the piston 120 from moving forward and backward. However, although the piston 120 is not advanced back and forth by strong wind or vibration, some clearance is provided between the end portion 122 and the rubber packing 142 of the piston in order to be easily manipulated by the attraction force. The spring-type electrode 148 is retained when the piston 120 is compressed when it is retracted, and retains an elastic force. By the combined action of the elastic force and the magnetic force acting between the magnet 143 and the magnet 144 to advance the reversed piston 120 to be restored to its original position, the solenoid valve solenoid valve 312 (313) If it is opened to operate the electric fan 410 immediately so that the odor is discharged to the outside of the building.

In the locking device, the piston part is firmly protected by the housing part, and the housing 130 is attached to the lock 150 so that it cannot be dismantled arbitrarily. There is also a need to temporarily release the function of the locking device for access to the roof, in this case, the administrator opens the lock 150, open the enclosure 130, and then release the safety device. The safety device refers to a part including the electrode 148 of the cylinder part. To release the safety device, the bolt 146 is loosened from the nut holder 145 and then the cylinder cover 147 is removed from the cylinder 140. Remove Since the electrode 148 is fixed to the cylinder cover 147, even if the piston 120 is retracted after the cylinder cover 147 is removed, no electricity is supplied between the electrodes 123 and 148. 312 and 313 also do not work. The process of restoring a released safety device is the reverse.

Thus applying the present embodiment can achieve the original purpose of the emergency door, while preventing the child or adolescents to open and close the emergency door arbitrarily.

The embodiments described above are within the scope of various changes, modifications, and equivalents of the present invention. Therefore, the present invention is not limited to the description of the examples.

According to the emergency door lock device of the present invention, in addition to the emergency door can be opened quickly by personnel in case of fire, in the case of children and adolescents to open the emergency door in everyday life, such as bell or siren attached to the automated material detection equipment It can ring, contact people, and cause water or odors to be airborne to alert people to prevent emergency doors from opening.
