As shown in FIGS. 1 and 2, the evacuation apparatus 100 is disposed through a bottom layer 1 that separates an upper layer and a lower layer, and a box- A lid 120 which is coupled to a hinge 120H at one side of the upper end of the frame 110 so as to be pivotally opened upward and a foldable slope 130 which closes the open front of the frame 110; A locking portion 160 for fixing the end of the foldable slope 130 to the frame 110, a tension member 141 extending from the slope 130, and a tension member 141 fixed to one end of the slope 130, And a lever 150 fixed to the slider 120 to open the cover 120 while being moved by the load of the slope 130.

The downward evacuation system constructed as described above will be described in detail below.

1 to 3, the frame 110 of the evacuation apparatus 100 is a box-like structure having a height of about 1 m to the extent that the escape person can be located therein. The bottom layer (slab) As shown in FIG. The upper end of the frame 110 fixed to the bottom layer 1 protrudes to the upper portion of the bottom layer 1. The lid 120 is coupled to the hinge 120H at one side of the upper end of the frame 110, The upper end of the frame 110 is closed by the frame 120.

As the upper end of the frame 110 is fixed to the bottom layer 1, most of the frame 110 is positioned in a downwardly protruding form from the bottom of the bottom layer 1,

An extended portion 110E of the frame 110 extending forward is formed in the frame 110 projecting downward from the ceiling of the lower layer and the front and bottom surfaces of the extended portion 110E are opened A slope 130 hinged to the frame 110 closes the front and bottom surfaces of the extension 110E.

The slope 130 is configured such that the slope plates 131 having a transverse length corresponding to the width of the extended portion 110E are coupled to each other by a hinge 131H so that one end of the slope 130 is connected to a side of the frame 110 And the slope 130 extends from the hinge 131H coupled portion to the bottom surface and the front surface of the extending portion 110E so that the front surface and the bottom surface of the extending portion 110E are closed do. In this state, the other end of the slope 130 is locked to the lock portion 160 mounted on the frame 110.

One end of the slope 130 composed of the slope plates 131 coupled with the hinge 131H is coupled to the hinge 131H of the frame 110 and the other end is locked to the lock portion 160, The slope 130 coupled to the hinge 131H when the lock unit 160 is unlocked is positioned in a state where the slope 130 is bent by gravity Downward to the floor of the lower layer.

Here, the locking portion 160 is a member for locking the end of the slope 130, and can be configured by various locking means.

As an example of the lock portion selected in the present invention, the lock portion 160 is an electromagnet 161 fixed to the frame 110. [ In case of the electromagnet 161, the electromagnet 161 is fixed to the end of the frame 110 and the electromagnet 161 is fixed to the end of the slab 130 when the power is not supplied, When an electric signal is inputted from a fire alarm or a switch after the end is fixed to the electromagnet 161, power is temporarily supplied to the electromagnet 161, and when the electromagnet 161 is in the non-magnetic state, the fixed slope 130 falls down .

Here, the lock portion 160 is not limited to the electromagnet 161, and the lock portion may be formed in place of the electromagnet using a member such as a latch or a hook that can be locked and unlocked by a motor.

On the other hand, the frame 110 and the slope plates 131 are connected to each other by a tension member 141 so that the opened slope 130 can be maintained to be inclined and spread from the frame 110 to the bottom of the lower layer.

The tensile material 141 not only supports the unfolded slope 130 but also transfers the load generated when the lock portion 160 is released and the slope 130 is unfolded downward to the lever 150, 150 are changed in position, so that the lid 120 is opened.

2 and 3, the lever 150 is curved at an angle of about 180 degrees. The curved end of the lever 150 covers the hinge 120H of the cover 120, The end of the transverse portion 150H of the lever 150 is extended to the inside of the extension 110E of the frame 110 and is horizontally positioned at the end of the transverse portion 150H of the lever 150 A tension member 141 is connected.

The levers 150 are respectively located on both sides of the frame 110 and the levers 150 are connected to each other through the link 151 to be integrated. And a support 153 connected to the cover 120 is fixed to the curved end. The support 153 is intended to increase the durability by making the lid 120 and the lug 150 more rigid.

In this state, the kinetic energy generated when the slope 130 is downwardly spread is transmitted to the end of the lateral portion 150H of the lever 150 through the tensile material 141, and the end of the lateral portion 150H of the lever 150 The curved portion 150C surrounding the hinge 120H is bent upward by 180 degrees so that the curved portion 150C and the end of the support base 153 The fixed lid 120 is opened upward.

When the cover 120 is completely opened, the end of the lateral portion 150H of the lever 150 is positioned at the lowermost point and a load is applied to the lever 150 along the extended slope 130 The lid 120 does not turn in the direction of covering the upper end of the frame 110 even if it further increases. This is because the load applied to the lid 120 acts vertically downward according to the characteristic of the curved portion 150C curved at about 180 degrees.

On the other hand, the tensile material 141 may be composed of a cable, a rope, or a foldable metal rod, and in the case of a flexible cable and a rope, the bundle may be configured to be unpacked by a load deployed by the slope 130 in a silent state, The cable and the rope may be wound around the tread and loosened when the slope 130 is unfolded.

The operation relationship of the downward evacuation system constructed as described above will be described in detail below.

2, the end of the slope 130 is fixed to the end of the frame 110 by the magnetic force generated by the electromagnet 161 as the lock portion 160, and the slope 130 Is positioned to cover the open front and bottom surfaces of the extension 110E of the frame 110. [

The lid 150 is positioned parallel to the bottom layer 1 with the lid 120 covering the top of the frame 110.

In this state, the evacuee recognizes the fire and activates the switch or the fire alarm activates, so that the external electrical signal is input to the control unit (not shown) of the top-down evacuation apparatus 100. When the external electrical signal is input, (About 1 to 60 seconds).

When the electric power is temporarily supplied to the electromagnet 161, the electromagnet 161 becomes a non-magnetic state by the supplied electric power. As shown in FIGS. 4 and 5, the slope 130 falls downward due to its own load At this time, the tensile material 141 connected to each slope plate 131 is unfolded so that the kinetic energy corresponding to the load of the slope 130 is transmitted to the end of the transverse portion 150H of the lever 150 through the tensile material 141, And it turns to the downward direction.

The lever 150 is connected to the lid 120 so that the transverse portion 150H of the lever 150 is moved downward and the lid 150 is fixed to the other end of the lever 150 about the hinge 120H of the lid 120, The frame 120 is pivoted upward about the hinge 120H and the frame 110 is opened.

The tension member 141 connected to the end is connected to the slope 130 which is stretched in a tense state so that the slope 130 is inclined at a predetermined angle so that the slope 130 is inclined at a predetermined angle. do.

The evacuator descends into the frame 110 through the open frame 110 as the lid 120 is pivoted. At this time, when the escapee sees the upper floor, the floor surface of the frame 110 can be seen, and can be located in the inner space of the frame 110 without fear of falling or the like.

The evacuator located in the inner space of the frame 110 is safely evacuated to the lower layer on the slope 130 spreading forward.

[Second Embodiment]

In the first embodiment, since the lever is configured to pivot around the hinge of the lid, the slope is unfolded by unlocking the lock, or if the intruder tries to forcibly open the lid, the lever can be turned and the lock can be unlocked have.

In the second embodiment, the cover is internally reinforced so as not to turn when the cover is forcibly opened. When the slope is unfolded, the reinforcing bar performs the function of the tread of the slope so that the escapee can easily escape to the lower layer will be.

In the description of the configuration according to the second embodiment, a detailed description of the configuration described in the first embodiment will be omitted, and the same reference numerals as in the first embodiment will be given.

FIG. 6 is a cross-sectional view of a top-down type evacuation apparatus according to a second embodiment of the present invention, and FIG. 7 is a cross-sectional view illustrating a state in which a slope of the top-

6 and 7, the slab plates 131 forming the slope 130 are formed with a reinforcing bar 133. [

And the reinforcing bar 133 supports the transverse portion 150H of the lever 150 in the locked state from below. Specifically, the reinforcing bar 133 extending from the slope plate 131 located on the front surface of the extended portion 110E supports the bottom end of the lateral portion 150H of the lever 150, and is located at the bottom of the extended portion 110E. The reinforcing strip 133 extending upward from the slope plate 131 supports the bottom surface of the transverse portion 150H of the lever 150.

A groove 133H having a radius larger than the radius of the curved portion 150C is formed in the rib 133 for supporting the curved portion 150C of the lever 150 and is spaced apart from the curved portion 150C.

When the intruder intends to forcibly lift the lid 120 covering the opening portion of the frame 110 in the thus configured downward type evacuating apparatus 100, the force is transmitted through the lever 150 to the transverse portion 150H downward As a force to turn.

At this time, in the absence of the reinforcing bar 133, the force of the intruder causes the flow of the lateral portion 150H, and when the flow repeats with the period, the lock portion 160 can be unlocked. Particularly, when a gap is formed between the slope plate 131 and the electromagnet 161, the magnetic force of the electromagnet 161 acting on the slope plate 131, which is a ferromagnetic body, abruptly weakens so that the intruder repeatedly lifts the lid If the force is applied, it may be unlocked.

In order to prevent this, it is possible to prevent the swing of the transverse portion 150H from being generated by supporting the transverse portion 150H by the reinforcing bar 133 formed on the slope plate 131, Can be prevented from being released.

When the external alarm signal is inputted from the fire alarm or the switch, the locking part 160 is released and the slope 130 is opened. On the slope 130, the slope plate 131 is lowered Is safely movable with the reinforcing bar 133 protruding perpendicularly to the slope plate 131 as a step plate.

As described in the first and second embodiments, the locking portion 160 is unlocked by the external electrical signal, so that the slope 130 is unfolded and the cover 120 is automatically opened by the load, It is safe to escape downstairs through an open lid.

Also, since the space in which the escape person is to be positioned by the height of the frame 110 is formed in the inside of the frame 110, the part where the escape person can see downward through the opened lid 120 is limited, There is an advantage that evacuation can be done easily.

Further, since the direction in which the slope 130 is expanded is located in the direction of the central portion of the area of the balcony, there is no problem that the slope is unfolded even when the lower-level members place the object under the frame 110. That is, there is an advantage that the space utilization of the balcony can be increased.

In the meantime, although not shown in the drawing, the lid of the top-down type escape ladder and the frame described above are filled with a sound insulating member. In particular, the floor of the bottom floor is prevented from transmitting noise to the upper or lower floor, A soundproofing pad is attached.
