In addition, the case 51 has a long hole 51a formed on one side facing the push unit 40 .

The reduction member 52 is accommodated in the inner space of the case 51 and includes a moving member 521 formed in a disk or spherical shape, a part of which is coupled to the upper surface of the moving member 521, and the remaining part is a long hole 51a. It may include a reduction piece 522 in the shape of a rectangular bar and a coil-shaped spring 523 protruding through the case 51 to the outside and disposed on the movement path of the push unit 40 described above.

The spring 523 may elastically support the moving member 521 or the deceleration piece 522 .

8 shows an example in which one end of the spring 523 is fixed to the wall surface formed in the inner space of the case 51 and the other end is fixed to one side of the movable member 521 .

The guide 53 is disposed in the inner space of the case 51 . 8, the guide 53 has a straight path 531 that guides the horizontal movement of the moving member 521 in the horizontal direction and extends obliquely at the ends of the straight path 531, and a reduction piece 522 is a case ( It may include a ramp 532 for guiding the inclined movement of the movable member 521 in the inclined direction 53 so as to be hidden in the inner space of the 51 .

Next, an operation example of the deceleration unit 50 described above will be described.

First, the first door member 30a and the second door member 30b open the door frame 10, that is, the first door member 30a, the second door member 30b, and the third door member. When the second door member 30b is pushed in a direction to close the second door member 30b with the 30c overlapping each other, the first damper 20a slides along the first guide rail 11a, and the second damper 20b moves the second door member 30b. It moves along the second guide rail 11b in conjunction with the movement of the first damper 20a to guide the smooth sliding movement of the first door member 30a and the second door member 30b (53).

Then, while the push unit 40 moves together with the first damper 20a, the deceleration piece 522 is pushed.

In this case, the moving member 521 moves along the straight path 531 and enters inward along the ramp 532 as shown in FIG. 8(b). Due to this, a portion of the reduction piece 522 protruding to the outside of the case 51 through the long hole 51a is hidden into the inner space of the case 51 to pass the push unit 40 .

At this time, the spring 523 is gradually expanded while the moving member 521 and the decelerating piece 522 move in the direction of the ramp 532 to generate a decelerating force in the first door member 30a.

Since the second door member 30b operates in conjunction with the first door member 30a by the interlocking part 80 , a deceleration force is also generated in the second door member 30b.

Therefore, the first door member 30a and the second door member 30b are prevented from closing at a high speed so as not to be injured even if a body part is caught between the second door member 30b and the door frame 10. can

On the other hand, when the push unit 40 passes through the deceleration piece 522, the push force on the deceleration piece 522 disappears and the tensile force on the spring 523 disappears, so that the spring 523 is compressed and returns to its original shape. is restored

Accordingly, the moving member 521 and the decelerating piece 522 are returned to their original positions as shown in Fig. 8(a).

At this time, the one-way clutch bearing B is embedded in the moving member 521 , and a shaft (not shown) installed on the one-way clutch bearing B is provided on the bottom surface of the reduction piece 522 .

Accordingly, the reduction piece 522 may be rotated only in the right direction with reference to FIG. 8 .

Therefore, when moving the second door member 30b in the right direction to open, the push unit 40 passes while rotating the deceleration piece 522 at an angle of 90 degrees in the right direction.

Furthermore, although not shown in the drawings, a restoring rotation means (not shown) may be installed on the shaft of the reduction piece 522 .

The restoring rotation means may be formed of a spring.

The restoration rotation means is elastically twisted and deformed when the reduction piece 522 is pushed by the push unit 40 and rotates in the right direction to support the reduction piece 522, and when the push unit 40 passes, the original As the shape is automatically restored, the reduction piece 522 is rotated to the left at an angle of 90 degrees. Due to this, the reduction piece 522 has the same shape as in FIG. 8(a) again.

On the other hand, the audible alarm unit 160 is installed on the door frame 10, is exposed to the outside, and generates a noise when the detection sensor 90 detects a human body and is configured to alert.

That is, the audible alarm unit 160 generates a warning to an intruder trying to break into the room through the door 1, and notifies the resident of the attempted intrusion.

As shown in FIGS. 10 and 13 , a fifth box B5 in which the audible alarm unit 160 is accommodated is installed on the outer surface of the door frame 10 .

At least one noise generating unit 162 is accommodated in the empty space of the resonance sound generating unit 161, is formed in a hemispherical shape and includes first and second members 1621 and 1622 that are male and female coupled to each other. can

Accordingly, when the first and second members 1621 and 1622 are combined, a spherical shape is formed.

The noise generating unit 162 generates noise by colliding with the inner surface of the resonance sound generating unit 161 by an electromagnet 164 , a cylinder 167 , and a collision plate 168 to be described later.

The noise generating unit 162 may be formed of a metal material to generate a large amount of noise.
