Description

An apparatus for preventing unlawful trespass in a fire door}

The present invention relates to a fire door that forcibly unlocks a fire door and prevents intrusion, and in particular, makes it difficult to flip an intrusion tool between the fire door and the door frame, thereby preventing damage to the fire door after attempting illegal intrusion. In addition, the present invention relates to an illegal intrusion prevention device of a fire door that enables a door to be opened in the room even after an illegal intrusion attempt.

In general, fire doors made of a solid steel structure are used for the entrance of a general building not only for the purpose of fire protection but also for the purpose of preventing illegal intrusion, since the fire door is made of a strong structure and thus cannot be broken or broken.

Since such fire doors are usually provided with one or more locks for the purpose of preventing illegal intrusion, even a key expert cannot easily open the lock.

As a result of the development of the lock function, when a thief or robber illegally enters the interior of the building, the lock installed on the door cannot be opened directly, the extension is inserted into the gap between the door frame and the door, and the door is forcibly flipped. There is a problem that the lock is forced out of the door frame and the door is forcibly opened.

As a method for solving the problem related to the illegal intrusion of the fire door, various devices have been proposed. Such a conventional fire prevention device of the fire door is a binding unit installed in the door 101 as shown in FIG. Consisting of the fastener 104 is mounted to the sphere 102 and the door frame 103, when the door 101 is closed, a gap 105 is formed between the fastener 102 and the fastener 104, The gap 105 is arranged to be exposed to the front of the door 101.

Therefore, the illegal intruder can easily insert the intrusion tool 106 into the gap 105 exposed to the front of the door to flip the binding hole 102.

Thus, the conventional fire door illegal intrusion prevention device when the binding device 102 installed in the door 101 and the fastener 104 mounted on the door frame 103 are engaged with each other, the binding device 102 and the fastener 104 Since the gap 105 is exposed in front of the gap between the door 101 and the door frame 103, an illegal intruder easily sandwiches the intrusion tool 105 between the binding hole 102 and the fixture 104. It is possible to attempt to release the lock 107 locked in the.

In addition, the conventional fire door illegal intrusion prevention device as described above, because the binding tool 102 can be flipped immediately by inserting the intrusion tool 106 into the gap 105 exposed in front of the door. There is a problem that the locking phenomenon of the sphere 102 and the fastener 104 easily occurs.

On the other hand, when the intrusion tool 106 folds the binding holes 102, as shown in Figure 4, the locking projections 108 protruding from the tip of the binding holes 102 are flipped to catch the hook 109 of the fixture 104. ) Will be caught.

In this way, if the locking projection 108 of the fastener 102 is caught by the locking ring 109 of the fastener 104, the door 101 cannot be opened, and thus an illegal intruder may intrude through the door 101 from the outside. It becomes impossible.

Therefore, the conventional fire door illegal intrusion prevention device as described above, since the illegal intruder attempts to invade using the intrusion tool 105 from the outside, the locking projection 108 and the locking ring 109 are locked and locked. In addition, the door may not be opened indoors, and the locks of the locking protrusion 108 and the locking ring 109 may not be released easily even in the outdoors, such that forced dismantling may be performed.

Accordingly, the present invention fundamentally solves the problems caused by the conventional fire door intrusion prevention device as described above, and the gap formed between the fasteners installed on the door and the fasteners mounted on the door frame when the fire door is closed to the front of the door. This prevents illegal intruders from easily inserting the intrusion tool into the gap between the fastener and the fastener, and prevents problems such as fastening of the fastener and the fastener by the insertion of the intrusion tool. The purpose is to provide a fire door illegal intrusion prevention device.

The intrusion prevention apparatus of the fire door of the present invention for achieving the above object is composed of a fastener provided on the front of the door frame, and a fastening fixture fixedly attached to the front end of the door and fastened to the fastener.

The fastener includes an attachment wall attached to the door frame, an inner wall vertically disposed at an inner end of the attachment wall, a hook formed to protrude from the tip of the inner wall, and perpendicular to an outer end of the attachment wall. A protruding outer wall and a fastening groove forming a space in which a binding hole of the door is inserted between the inner wall and the outer wall; The fastener is coupled to the front end of the door is coupled to the coupling portion, the connecting portion extending from the coupling portion toward the fixture, the insertion portion provided in the front end of the connecting portion to be fitted into the fastening groove of the fixture, the locking projection protruding to the end of the insert and It is formed to extend to the rear of the insert portion comprises an extension covering the outer wall of the fixture.

The fire door intrusion prevention apparatus of the present invention is fixed to the door frame and the door is closed in the state in which the fastener is mounted on the door, the extension of the fastener mounted on the door covers the rear wall of the fastener mounted on the door frame from the top Because of the cycle, the groove formed between the fastener and the fastener is not exposed vertically, so it is difficult to pinch the intrusion tool between the fastener and the fastener from the outside. Therefore, it is possible not only to prevent illegal intrusion at the source, but also to at least delay the intrusion, thereby creating anxiety for the intruder, thereby removing the intention to invade.

In addition, the fire door intrusion prevention apparatus of the present invention does not deform the binding holes mounted on the door even if attempts to invade the door is not broken, it is possible to obtain the effect of allowing the door to be opened in the room as it is even after illegal intrusion. .

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

1 is a cross-sectional view showing a state in which the door frame 1 and the door 2 equipped with a fire door illegal intrusion prevention apparatus according to the present invention are in close contact with each other, and FIG. 2 is a perspective view showing only the device according to the present invention separately. As shown in these figures, the device according to the invention is basically a fastener 3 mounted on the door frame 1 and a fastener fastened to the door 2 and fastened to the fastener 3. It consists of (4).

The fastener 3 has an attachment wall 31 attached to and coupled to the door frame 1, an inner wall 32 disposed perpendicularly to an inner end of the attachment wall 31, and a tip of the inner wall 32. A hook 33 protruding from the wall, an outer wall 34 protruding perpendicular to the outer end of the attachment wall 31, and a door 2 mounted between the inner wall 32 and the outer wall 34. It is provided with a fastening groove 35 constituting a space in which the fastening holes 4 are inserted.

In addition, the binding port 4 is a coupling portion 41 is fitted to the front end of the door 2, the connecting table 42 extending from the coupling portion 41 toward the door frame 1, the connecting table 42 The insertion part 43 is provided at the front end of the fastener 3 and inserted into the fastening groove 35 of the fastener 3, the locking protrusion 44 protruding from the front end of the insertion part 43, and the rear of the insertion part 43. It is formed to include an extension portion 45 extending to cover the outer wall 34 of the fastener (3).

In the apparatus of the present invention having such a structure, the fastener 3 and the fastener 4 have a door frame such that the fastening ring 33 of the fastener 3 and the fastening protrusion 44 of the fastener 4 face each other. It installs in (1) and the door (2), respectively.

The fastener (3) is fixed to the door frame (1) using a double-sided tape and screws, the fastener (4) for the windscreen protruding to the front end of the door 2 by applying an adhesive to the coupling portion 41 It fits into the flange part 21 and couples.

In this way, when the fastener 3 is mounted on the door frame 1 and the fastener 4 is installed on the door 2, when the door 2 is closed, the insertion part 43 of the fastener 4 is fixed to the fastener ( 3) is engaged in the state entered into the fastening groove (35).

At this time, the locking projections 44 of the binding hole 4 and the locking ring 33 of the fastener 3 are only coupled to face each other, but are in contact with each other and are not bound.

On the other hand, when the fastener 3 and the fastener 4 are brought into contact with each other by closing the door 2, the extension 45 of the fastener 4 moves the outer wall 34 of the fastener 3 upward. Completely covered by

Therefore, the gap G formed between the insertion portion 43 of the binding tool 4 and the outer wall 34 of the fastener 3 is covered by the extension 45 so that the outer wall is not directly exposed in the vertical state. It is indirectly exposed through the gap g formed between the 34 and the extension 45.

In this way, since the gap g is disposed not to face the front of the door but to the side, the lock 5 mounted between the door frame 1 and the door 2 is forcibly opened and flipped. It is difficult to insert the intrusion tool (6) between the fixture 3 and the binding port (4).

That is, if the gap (g) formed and exposed between the fixture (3) and the binding hole (4) is arranged vertically, the intrusion tool (6) can be easily inserted from the front, the gap (g) to the side Since it is formed, the intrusion tool (6) can not be easily used because it must be inserted and flipped from the side, and the intrusion tool (3) formed integrally with the binding port (4) is made of a hard material ( 6) can not be easily broken using the extension 45 is also difficult to try to break in.

Thus, by adding the extension portion 45 to the binding port 4 according to the device of the present invention, an illegal intruder can insert the intrusion tool 6 between the binding port 4 and the fastener 3. Not only will it be difficult at the source, but because at least the extension 45 must be flipped, a time delay may be generated during the time, thereby creating a psychological anxiety of an illegal intruder, and thus giving up the intrusion attempt. According to the device as well as to prevent damage to the door.

On the other hand, even if the extension part 45 is damaged or forcibly flipped in the case, the locking projection 44 and the locking ring 33 are provided inside the binding tool 4 and the fixing tool 3. Therefore, in order to forcibly open the lock 5 by the illegal intruder who does not know whether the locking protrusion 44 and the locking ring 33 are provided, the insertion hole 43 is deformed when the intrusion tool 6 is inserted and flipped. The machine 44 and the locking ring 33 are locked to each other by binding.

Therefore, since the opening of the door 2 is completely blocked, intrusion is fundamentally impossible, thereby preventing illegal intrusion.

1 and 2 illustrate the extension part 45 in a horizontal state to cover only the outer wall 34 of the fastener 3, but the tip of the extension part 45 is formed by the letter “b”. You can also make a shape that is bent at a right angle to bend inward, such as shape.

By making the extension part 45 in a bent form as described above, illegal intrusion using an intrusion tool can be prevented more effectively.
