A perspective view showing a state where a fully open emergency door according to a first embodiment of the invention is mounted on a bus.

As shown in FIG. 1, the fully open emergency door 100 according to the present invention may be installed on a wall 1 or a door (collectively referred to as a 'wall') or dividing a household in an apartment, or as shown in FIG. 8. It can be installed in a vehicle such as a bus. Emergency door 100 of the present invention is configured to escape from the emergency escape passage formed by the operation of the emergency evacuation door located in the partitioned space.

As shown in FIG. 2, the emergency door 100 has a quadrangular frame 110 positioned inside the wall 1 and a passage located inside the frame 110 and being an inner space of the frame 110. When the electrical signal is inputted to the closing plate 140, which is a closing member to fall outside the frame 110 to fall outside, and is located on both sides of the closing plate 140 to close the frame 110, when the electrical signal is input Falling out of the frame 110, the cover 160 and the closing plate 140 and the cover 160 is generated magnetic force to be fixed to the frame 110, the external electrical signal input from the sensor or alarm according to the emergency It includes electromagnets (151, 152) that the magnetic force is destroyed when the power is temporarily applied by.

Hereinafter, a fully open emergency door configured as described above will be described in more detail.

As shown in FIGS. 2 to 7, the rectangular frame 110 has an upper horizontal bar 111 formed of a rectangular pipe on the upper side and a lower horizontal bar 121 on the lower side, and the upper horizontal bar 111 and the lower side. Horizontal bars 121 are positioned to face each other.

The bottom of the upper horizontal bar 111 of the frame 110, the slot 111S is formed long in the longitudinal direction, and three through

holes

113A, 113B are formed at the front of the upper horizontal bar 111 at intervals. On the back, through holes 113B are formed at both ends, respectively. Here, the through

holes

113A and 113B formed in the upper horizontal bar 111 are through holes formed to install the

electromagnets

151 and 152 inside the upper horizontal bar 111.

And concave groove 121H is formed long in the longitudinal direction on the upper surface of the lower horizontal bar 121.

The closing plate 140 is fixed by the first electromagnet 151 in a state of being inserted into the slot 111S formed in the upper horizontal bar 111.

Specifically, the U-shaped upper bending plate 131 bent 180 degrees is inserted into the slot 111S of the upper horizontal bar 111 so as to be opened downward and welded thereto.

In addition, a through hole 131A is formed in the middle of the length of the upper bending plate 131, and the closing plate entered into the upper bending plate 131 with the first electromagnet 151 positioned corresponding to the through hole 131A. The first electromagnet 151 is attached to the upper end of the 140.

As the upper end of the closing plate 140 is attached to the first electromagnet 151 sandwiched by the through hole 131A of the upper bending plate 131, the closing plate 140 is moved toward the inside of the upper bending plate 131. It is placed in the inserted state.

The lower end of the closing plate 140 fixed to the first electromagnet 151 is positioned in an inserted state of the lower bending plate 133. Here, the lower bending plate 133 is also a U-shaped bending plate bent 180 degrees and the lower bending plate 133 positioned to be opened upward is seated in the concave groove 121H formed in the longitudinal direction of the lower horizontal bar 121. The recessed groove 121H is a groove formed at a radial depth of the lower end of the lower bending plate 133.

Accordingly, the lower end of the lower bending plate 133 is seated in the recessed groove 121H of the lower horizontal bar 121 while the lower end of the closing plate 140 is inserted into the open portion of the lower bending plate 133. The bending plate 133 is placed upright, and when the closing plate 140 is positioned inward of the lower bending plate 133, the lower bending plate 133 and the lower horizontal bar 121 may be caused by the weight of the closing plate 140. Will fall outside).

As described above, when the closing plate 140 fixed to the first electromagnet 151 falls away from the first electromagnet 151 where the magnetic force is dissipated, the upper end of the closing plate 140 is the lower end of the upper bending plate 131. The bottom of the closing plate 140 is located downward, and conversely goes deeper into the lower bending plate 133.

As the upper end of the closing plate 140 is out of the upper bending plate 131, the closing plate 140 falls outside the frame 110 together with the lower bending plate 133 without being supported.

To be configured in this way, when the lower end of the closing plate 140 touches the inner bottom of the lower bending plate 133, the upper end of the closing plate 140 may escape from the upper bending plate 131. There is a correlation between the height of the upper bending plate 131 and the depth of the lower bending plate 133.

Meanwhile, in a state in which the closing plate 140 is fixed to the first electromagnet 151, the upper end of the closing plate 140 is fitted to the upper bending plate 131, and the lower end of the closing plate 140 has a lower bending plate ( 133 is inserted. Therefore, the space between the upper horizontal bar 111 and the lower horizontal bar 121 is closed by the closing plate 140 and the lower bending plate 133, even if an impact is applied to the closing plate 140, the closing plate 140 As the upper end of the support plate is supported by the upper bending plate 131, the closing plate 140 does not leave the frame 110, even if the lower bending plate 133 is supported by the closing plate 140 Accordingly, the lower bending plate 133 does not leave the frame 110.

On the other hand, the cover 160 is located on the front and rear of the closing plate 140 fixed to the first electromagnet 151.

2, 4 and 5, the cover 160 is an area that can cover the square frame 110, through holes formed at both ends of the upper horizontal bar 111 of the square frame 110 ( The upper end of the cover 160 is fixed to both side second electromagnets 152 fixed to the upper bending plate 131 through 113B).

As shown in FIG. 2, three through

holes

113A and 113B are formed at one side of the upper horizontal bar 111 at intervals, and through holes 113B are formed at both ends at the other side thereof. The through hole 113A formed at the center of the through hole is a through hole for positioning the first electromagnet 151 shown in FIG. 4, and the through hole formed at both ends of one side and both ends of the other side as shown in FIG. 5 ( 113B) Also, the second electromagnet 152 is a through hole formed in the frame 110 so that the second electromagnet 152 enters the inside of the upper horizontal bar 111 and can be attached and fixed to the outer surface of the upper bending plate 131.

The cover 160 is disposed on the front and rear of the frame 110 is attached to the second electromagnet 152 configured as described above, so that the magnetic force is concentrated in the cover 160 is fixed by the magnetic force of the second electromagnet 152. The steel plate 161 of the ferromagnetic material is fixed to the upper inner surface of the cover 160 to correspond to the second electromagnet 152. As the steel plate 161 of the ferromagnetic material is fixed in a protruding form with respect to the inner surface of the cover 160, when the steel plate 161 contacts the second electromagnet 152, the magnetic force of the second electromagnet 152 is changed to the steel plate 161. ), The magnetic force can generate greater force than is directly attached to the inner surface of the flat cover (160).

In addition, a sound insulation pad 163 may be attached to an inner surface of the cover 160 to fill a space formed between the upper horizontal bar 111 and the lower horizontal bar 121 of the frame 110. Therefore, when the cover 160 is attached and fixed to the second electromagnet 152, a sound insulating pad 163 is positioned between the closing plate 140 and the cover 160 to block noise transmission between generations.

In the emergency door 100 configured as described above, the magnetic force is generated when the first electromagnet 151 and the second electromagnet 152 are not supplied with power (no power supply state). As the electromagnet which is in a non-magnetic state, the closing plate 140 is attached to the first electromagnet 151 in the non-powered state, and the cover 160 is attached to the second electromagnet 152 in the non-powered state, and a fire alarm, a sensor, and a switch When the electrical signal is input to the control unit (not shown) from the back, the control unit supplies power to the first electromagnet 151 and the second electromagnet 152 to be in a non-magnetic state, the closing plate 140 and the side cover 160 Is configured to fall by its own load.

Hereinafter, the operation relationship of the fully open emergency door configured in this way will be described in detail.

As shown in FIG. 1, the cover 160 of the emergency door 100 is exposed to the wall 1 partitioning each generation of the apartment house, and the frame 110 of the emergency door 100 is the wall 1. It is fixed inside of.

In the installation of the emergency door 100, it is possible to install the frame 110 in the form of the form of the wall (1) during the construction of the apartment house, otherwise forming a square hole in the pre-installed wall and the emergency door 100 The frame 110 can be fitted into the square hole for construction. In this case, when the frame 110 is formed in the form of a formwork, protrusions (not shown) may be formed on the outer surface of the frame 110 to wrap the protrusions so that the frame and the wall may be integrated. In addition, in the case of the construction by drilling a square hole in the pre-installed wall to form a fastening piece on the outer surface of the frame, it may be fixed to the wall with an anchor bolt or the like through the fastening piece.

When the emergency door 100 is installed on the wall 1 as described above, when a fire is detected by a fire alarm or a fire detection sensor in the household, an electric signal is generated from the fire alarm or the sensor, and the signal is an emergency door ( It is input to a control unit (not shown) of 100.

When a signal is input to the controller, the controller supplies power to the first electromagnet 151 and the second electromagnet 152 temporarily (about 1 to 60 seconds).

When power is temporarily supplied to the first electromagnet 151 and the second electromagnet 152, the first electromagnet 151 and the second electromagnet 152 are temporarily incapable of magnetism, and the first electromagnet 151 The closing plate 140 attached to the cover 160 and the cover 160 attached to the second electromagnet 152 are dropped by their own load.

The first electromagnet 151 and the second electromagnet 152 are simultaneously demagnetized, and the closing plate 140 and the cover 160 are separated and dismantled at the same time. Hereinafter, disassembly of the cover 160 will be described first.

As shown in FIGS. 5 and 6, the second electromagnet 152 is fixed to the upper bent plate 131, and is normally covered by the magnetic force of the second electromagnet 152 in a non-powered state. Is respectively fixed to the front and rear of the frame 110, but when the power is supplied to the second electromagnet 152 is in a non-magnetic state, the cover 160 falls down and is disassembled. At this time, the lower end of the through hole 113B formed in the upper horizontal bar 111, that is, the bottom surface of the upper horizontal bar 111 so that the second electromagnet 152 can be installed, is cut off so that the steel plate 161 of the cover 160 is not caught. 111C is formed. Accordingly, the cover 160 is removed while the second electromagnet 152 is in a non-magnetic state.

On the other hand, the first electromagnet 151 is normally fixed to the closing plate 140 over the through hole 131A formed in the upper bending plate 131 as shown in FIGS. That is, the first electromagnet 151 is not fixed to the frame 110 and the upper bending plate 131, and is positioned in a state spanning the through hole 131A of the upper bending plate 131. In this state, when the power is supplied and the first electromagnet 151 is in a non-magnetic state, the closing plate 140 falls downward due to its own weight, and the first electromagnet 151 falls out of the upper bending plate 131.

The reason why the first electromagnet 151 is not fixed to the frame 110 or the upper bent plate 131 is that when the first electromagnet 151 and the closing plate 140 are attached for a long time, the closing plate is normally closed. 140 is magnetized to generate a magnetic force, in which case the closing plate 140 and the first electromagnet 151 may not be separated even when the first electromagnet 151 is in a non-magnetic state.

In order to prevent this, the lower edge of the first electromagnet 151 is chamfered. Therefore, the edge of the through hole 131A of the upper bending plate 131 is inserted into the chamfer 161C of the first electromagnet 151 while the first electromagnet 151 is attached to the closing plate 140. In this state, when the first electromagnet 151 is in a non-magnetic state, the edge of the through hole 131A of the upper bending plate 131 serves as a wedge for separating the closing plate 140 and the first electromagnet 151 and closed. Even if the plate 140 is magnetized, it is configured to be easily separated from the first electromagnet 151 by the weight of the closing plate 140. In addition, since the first electromagnet 151 is not fixed to the upper bent plate 131, when an impact is applied to the closing plate 140, the shock transmitted to the first electromagnet 151 is absorbed, and the first electromagnet ( 151 and the closing plate 140 can be prevented from being separated.

However, even if the closing plate 140 is magnetized, when the weight of the closing plate 140 is large, the first electromagnet 151 may fall due to the load of the closing plate 140 even if the first magnet 151 is in a non-magnetic state. In this case, the upper bending plate 131 may be welded and fixed while the first electromagnet 151 is inserted into the through hole 113B.

Therefore, when the first electromagnet 151 is in a non-magnetic state, the closing plate 140 falls downward, and the lower end of the closing plate 140 enters the inside of the lower bending plate 133 and the upper end of the closing plate 140 is The upper bent plate 131 is positioned below it.

As such, when the closing plate 140 falls downward, the closing plate 140 is moved out of the upper bending plate 131 which fixes and closes the closing plate 140, and the closing plate 140 and the lower bending plate 133 are front of the frame 110. Or fall backwards.

As the side cover 160 and the closing plate 140 are dismantled out of the frame 110 as described above, the inside of the frame 110 of the emergency door 100 is completely opened.

The evacuator returns the cover 160, which has fallen to the other generation's area, to the frame 110 of the emergency door 100 while evacuating to another generation through the inside of the frame 110 of the fully opened emergency door 100.

At this time, the power supply which was temporarily supplied to the second electromagnet 152 is cut off, that is, the magnetic force is temporarily lost and then restored. The steel plate 161 of the cover 160 is fixed to the second electromagnet 152. .

In this way, by fixing the cover 160 in the direction of evacuation to the frame 110 of the emergency door 100, the flame is prevented from moving from generation to generation to evacuation to other generations, especially inflow of toxic gas Can be blocked.

Meanwhile, the emergency door 100 illustrated in FIG. 7 is configured to attach the first electromagnet 151 to the upper end of the upper bending plate 131, and corresponds to the first electromagnet 151 on the upper end of the closing plate 140. Thus, the steel sheet 140P is formed at right angles with the closing plate 140.

As the steel plate 140P is formed at the top of the closing plate 140 at right angles as described above, the magnetic force of the first electromagnet 151 is concentrated on the steel plate 140P so that the attachment of the closing plate 140 becomes more powerful.

8 is a perspective view illustrating an example in which the emergency door 100 according to the first embodiment described above is mounted on a large vehicle such as a bus 3 or the like. In particular, in the case of special vehicles such as armored vehicles that require rapid loading and unloading of troops, emergency doors may be mounted on armored vehicles to increase the speed of getting on and off.

Second Embodiment

The emergency door in the first embodiment has a configuration in which the closing plate is located inside, the cover is located on both sides of the closing plate, and the closing plate and both sides of the cover are disassembled by a temporary power supply, so that the emergency door is completely opened. .

In the second embodiment described below, the closing plate positioned on the inside of the frame and the frame are matched with the electromagnet, and the closing plate matched to the frame by the temporary power supply is disassembled from the frame so that the emergency door is opened. It is a fully open structure.

9 is a perspective view showing a fully open emergency door according to a second embodiment of the present invention, Figure 10 is an exploded perspective view of the emergency door shown in Figure 9, Figure 11 is a view of the emergency door shown in Figure 9 It is a cross section. 12 is a cross-sectional view illustrating a process of opening an emergency door as electric signals are input from a sensor and power is supplied to an electromagnet.

As shown in FIGS. 9 to 10, the emergency door 100 includes a plurality of frames 110 fixed to the wall 1 and a closing member positioned inside the frame 110 to close the frame 110. The closing plate 141 and a third electromagnet 153 for fixing the closing plate 141.

More specifically, the frame 110 is a frame of a circular or rectangular structure, the inner surface of the frame 110 is higher corresponding to the center of thickness of the frame 110 and lowered downward toward the front and rear of the frame 110 The inclined surface 115 is formed on both sides.

In addition, two closing plates 141 are positioned inside the frame 110. The thickness of the closing plate 141 is about half the thickness of the frame 110, and the edge of the closing plate 141 is the frame 110. Has an inclined surface 141S corresponding to the inclined surface 115.

Therefore, when the closing plate 141 is positioned on the front and rear of the frame 110, the inclined surface 141S of the closing plate 141 is in contact with the inclined surface 115 of the frame 110, and both closing plates 141 are framed. It is in contact with each other at the thickness center of 110.

Meanwhile, in some cases, two third electromagnets 153 may be mounted on the frame 110 as illustrated in FIGS. 10 and 11, or one of the two closing plates 141 which are in contact with each other, as illustrated in FIG. 12. Can be mounted on the side.

10 and 11, when two third electromagnets 153 are mounted on the frame 110, the third electromagnets 153 are mounted on the upper horizontal bar 111 of the frame 110. The two inclined surfaces 115 are respectively fixed inside.

Therefore, when the current of the third electromagnet 153 is not supplied, the steel plate 140P fixed to both closing plates 141 is attached and fixed to the third electromagnet 153 mounted on the inclined surface 115 of the frame 110. do.

In this state, when the power is temporarily supplied to the third electromagnet 153, the third electromagnet 153 is in a non-magnetic state, so that the closing plate 141 slides along the inclined surface 115 of the frame 110 and the frame 110 To be dismantled.

On the other hand, as shown in Figure 12, when the third electromagnet 153 is mounted on either one of the both side closing plate 141 and also in normal times both side closing plate 141 by the magnetic force of the third electromagnet 153 Are attached to each other to close the inside of the frame 110, but when the power is temporarily supplied, the third electromagnet 153 is in a non-magnetic state so that both closing plates 141 are along the inclined surface 115 of the frame 110. By sliding off, the frame 110 is opened.

In this case, a power terminal 116 is formed on the inclined surface 115 formed on the upper horizontal bar 111 of the frame 110 on the closing plate 141 on which the third electromagnet 153 is mounted, and on the closing plate 141.

The cover may be configured to be attached to the frame with a larger attraction force than the magnetic force of the cover.

In the emergency door of the present invention configured as described above, the pole switching of the electromagnet means not only the mutual switching between the N pole and the S pole, but also the mutual switching between the polarity (N pole or S pole) and the nonpolar pole.
