Description

Panic bar module for fire doors and connectors used therein {PANIC BAR MODULE FOR A FIRE DOOR AND THE CONNECTOR FOR THE SAME}

The present invention relates to a panic bar module for fire doors and a connector used therein, and more specifically, to a panic bar module for fire doors in which a panic bar unit and a cup handle are modularized by connectors, and a connector used therein.

Recently, panic bars or push-bar devices (hereinafter referred to as 'panic bar units' in this specification) are installed on the interior side of fire doors or emergency exit doors to prevent fire, earthquake or other emergencies. In case a situation occurs, if you push the panic bar or push bar (hereinafter referred to as 'panic bar' in this specification) from the inside, the door is unlocked, allowing you to quickly go outside.

The reason for using such a panic bar device is that doors with conventional door locks could be opened only by holding and turning the handle of the lock and pushing or pulling. The unlocking process of this conventional door lock is It may seem simple, but when an emergency situation arises, it not only delays the time to escape from the house or office, but also causes some people to forget their composure and become nervous when an emergency situation arises. In fact, unlocking a very simple door lock can be difficult. This is because there were cases where people forgot how to operate it and were unable to evacuate and suffered damage.

Therefore, in order to enable rapid evacuation in the event of an emergency such as a fire or earthquake, locking devices cannot be installed on emergency exit doors by law. Recently, panic bar devices have been encouraged to be replaced, and are especially mandatory in facilities such as hospitals. It is happening now

However, even in this case, no one can enter the interior from the outside, or at least a door handle similar to the conventional case is installed so that the interior can only be entered by unlocking or at least turning the handle. The panic bar unit and the door handle on the outdoor side are paired, and in this specification, they are collectively referred to as 'panic bar modules'.

And, as a panic bar module for such a fire door or emergency exit door, Republic of Korea Patent Publication No. 10-0465822, whose invention title is “Emergency Exit Door Lock,” is disclosed as the first prior art.

When the first prior art is described with reference to FIGS. 1A and 1B, the base 20 is fixed to the interior side of the emergency exit door 1; A latch 30 is rotatably coupled to the base and has a tip 31 that goes in and out of the base and is caught on the door frame side; The front end of the latch always protrudes, and an elastic member 40 elastically pulls the rear end of the latch to prevent it from opening arbitrarily when the door is closed; A center portion 51 rotatably coupled to the base, a support portion 52 extending from the center and the tip arranged to support the rear end of the latch, and an extension portion extending from the center at a predetermined angle with the support portion ( 53) is integrated with an operating lever 50 that is operated by a push bar 4 disposed on the indoor side of the door 1 to lift the rear end of the latch; A cam (60) that accommodates the tip of the support portion (52) of the operating lever and is rotatably disposed on the base and is operated by a handle (70) installed on the emergency exit side of the door, but operates the operating lever regardless of the rotation direction of the handle. ) is characterized by having a.

In addition, the cam 60 is rotatably disposed on the base 20 and includes a body 61 connected to the handle 70 through a spline axis 71 in the shape of a square bar, and an operating lever on the upper surface of this body. A receiving groove 62 formed to accommodate the tip of the support portion 52, a first inclined surface 63 that starts from this receiving groove and slopes upward in one direction along the edge of the body, and is accommodated to correspond to the first inclined surface. It is characterized by having a second inclined surface 64 that slopes upward from the groove toward the other side along the edge of the body.

In addition, the body 61 of the cam 60 is provided with a rotation axis that is coupled to the through hole 28 of the base 20 and has a shaft hole 61b formed therein so that the spline shaft 71 is coupled thereto, and at the end of the rotation shaft. It is characterized by a snap ring (61c) installed to prevent the rotation axis from being separated from the base.

Therefore, according to the emergency exit door lock of the first prior art, when a person wants to exit from indoors through an emergency exit, the push bar is pushed to operate the operating lever, thereby releasing the latch and opening the door. That is, the latch is released from the door frame by the rotation of the operating lever and the door is easily opened. As a result, the door can be easily opened indoors by pushing the push bar with a part of the body without necessarily using the hands, which has the effect of allowing easy opening of the door and escape even in an emergency situation. And, even if you want to enter the room from the emergency exit, if you hold the handle and rotate it in any direction, the operating lever is linked and the latch is released, which has the effect of allowing you to easily open the door from the emergency exit side.

Meanwhile, it is a technology that adopts a panic bar device but adds the function of locking or unlocking using a key to prevent unauthorized people from entering the room from the outside. Republic of Korea Patent Publication No. 10-0874595 (name: Panic) A technology such as (device) has been disclosed, and this will be outlined with reference to FIGS. 2A and 2B. In the case of the handle operating unit 47 of the door lock device 20, the connection bar 67 in the shape of a square bar is used to unlock and release the device. The square groove-shaped insertion hole 63 of the rotating body 60, the square hole 48a of the outer cylinder member 48 and the square hole 53b of the inner cylinder member 52 are operatively connected to the rotation operation unit 50. By rotating the door handle 80, the rotation operation unit 50 operates by rotating the door handle 80.

That is, in addition to the pressing action of the touch bar 12, the rotational force of the door handle 80 passes through the connecting bar 67, the inner cylinder member 52, and the outer cylinder member 48, and the rotation operation part of the outer cylinder member 48 Through the rotation operation part 50 that is transmitted to (50) and rotates, the lower end of the touch operation bar 40 is raised, and through this, the latch bolt 26 and the dead bolt 32 are connected to the support cap 22. ) It is rotated and transported inside, eventually opening the locked door.

On the other hand, as the third prior art for a panic bar module that combines a panic bar device on the inside of the door and an external handle opening and closing device on the outside, Republic of Korea Patent Publication No. 10-2026664 (name: Door opening notification and panic bar position display) device) is disclosed.

If this is explained with reference to FIG. 3, it includes a base bar 1001 fixed to the inner surface of the door 1, and a push bar 1002 that is pressed into/restored to the base bar 1001 through spring action. A panic bar (1000) composed of; A base plate 12 installed on the outer surface of the door 1, a handle lever 15 rotatably installed on the base plate 12 about a rotation axis 14 and held by the user, and the handle an external handle (11) protruding from the end of the lever (15) and including a plunger (19) disposed along the rotation axis (14); It is provided on the inner surface of the door 1 between the panic bar 1000 and the external handle 11 and is coupled to the lift arm 2001 and the plunger 19 rotated by the push bar 1002. It is configured to include a lift cam 2002 that rotates and raises and lowers the lift arm 2001, so that the lift arm 2001 moves according to the press-in/restoration of the push bar 1002 or the rotation of the handle lever 15. A door lock (20) that rotates the deadbolt (22) to enable locking/unlocking; Includes.

In addition, as is well known, the door lock 20 is coupled and rotated to the plunger 19 of the lift arm 2001 and the handle lever 15, which are rotated by the push bar 1002, and is used as a lift to raise and lower the lift arm 2001. It is configured to include a cam 2002, and the '+'-shaped plunger 19 is configured to have a '+' groove by pressing/restoring the push bar 1002 or by rotating the handle lever 15. 2002) is rotated, and the lift arm 2001 rotates the deadbolt 22 accordingly to perform locking/unlocking.

In this way, the rotation coupling method of the connector and cam connecting the handle on the outside of the door and the panic bar device is changed from the conventional '口' shape to a '+' shape, so in the process of simplifying the panic bar device, it is operated as much as possible. As the diameter of the rotating shaft is reduced, the '+' shape is more advantageous than the '口' shape as it is compact yet reliably transmits rotational force.

On the other hand, as the fourth prior art for a panic bar module combining a panic bar device inside the door and an external handle opening and closing device on the outside, Republic of Korea Patent Publication No. 10-2026664 (name: door opening notification and panic bar position) display device) is disclosed.

Hereinafter, the fourth prior art will be described in detail with reference to FIGS. 4 to 9.

As shown in FIGS. 4 to 9, the panic bar assembly 10 according to the fourth prior art may be largely composed of a panic bar unit 100, a door latch unit 300, and a handle unit 500. .

The panic bar unit 100 functions to unlock the door from the inside of the door, and the door latch unit 300 functions to maintain the door in the closed position and lock the door. The handle unit 500 functions to open the door from the outside of the door.

When the access is permitted, the lock state of the door latch unit 300 is released by the operation of the handle unit 500, and the door can be opened by the operation of the handle 510. However, in the case of access control, the operation of the handle unit 500 is blocked from being linked to the operation of the door latch unit 300, preventing the door from being opened by the operation of the handle 510.

The panic bar unit 100 includes a main frame 110 installed on the door, a sub-frame 120 coupled to one side of the main frame 110, and arranged in parallel with the sub-frame 120 and directed toward the outside of the door. It includes a panic bar 130 that is movably coupled.

Figures 6 and 7 are perspective views showing the main configuration of the panic bar unit and the door latch unit. Figure 8 is a perspective view showing the installation state of the blocking module and the handle operating unit. Figure 9 is a perspective view showing a blocking module and a handle operating unit.

As shown in FIG. 6, the return bracket 160 movably supports the panic bar 130. The return bracket 160 guides the panic bar 130 toward the main frame 110 when an external force is applied to the panic bar 130 by the user, and returns the panic bar 130 to its original position when the external force is removed. I order it.

A movable bracket 170 that moves the door latch 330 according to the operation of the panic bar 130 is installed adjacent to the return bracket 160. The movable bracket 170 is a type of link with a predetermined length, and is rotatably coupled to the latch support frame 310 by a rotation pin 172 to operate the door latch 330 using the principle of a lever. The movable bracket 170 includes a rotary pin 172 that serves as a support point of the lever, a first movable part 174 formed at an end far from the rotary pin 172, and a second movable part 174 formed at an end close to the rotary pin 172. Includes a movable part 176.

The rotation pin 172 is rotatably coupled to the latch support frame 310 of the door latch unit 300 while being rotatably inserted adjacent to one end of the movable bracket 170. The movable bracket 170 is rotatably supported on the latch support frame 310 by the rotation pin 172.

When the panic bar 130 approaches the main frame 110 by an external force and presses the first movable part 174 of the movable bracket 170 toward the main frame 110, the second movable part centers on the rotation pin 172. As (176) is lifted, the door latch 330 is lifted. Through this operation, the fixed state of the door latch 330 is released and the door is opened.

The door latch unit 300 largely includes a door latch 330, a latch support frame 310 and a latch cover case 350 that cover the door latch 330, and the latch support frame 310 is a door latch. It rotatably supports 330 and the movable bracket 170, and serves to support the handle operating unit 550 connected to the handle 510, which will be described later. A latch support portion 312 on which the door latch 330 is rotatably supported is protrudingly formed on one side of the latch support frame 310. A bracket support portion 314 that rotatably supports the movable bracket 170 is protrudingly formed on the other side of the latch support frame 310 facing the latch support portion 312. Additionally, a head support portion 316 for supporting the handle operating portion 550 is formed protruding adjacent to the bracket support portion 314.

As shown in FIGS. 6 and 7, the door latch 330 includes a latch hinge 332 rotatably coupled to the latch support 312, and a locking portion formed on one side with respect to the latch hinge 332 ( 334) and a locking release portion 336 formed on the other side.

The latch hinge 332 has a cylindrical pin shape and is formed integrally with the locking portion 334 and the locking release portion 336, and both ends are rotatably inserted into the latch support portion 312.

The latch release part 336 is disposed on the movable bracket 170 side and comes into contact with the second movable part 176 of the movable bracket 170. When opening the door from the indoor direction, if the second movable part 176 is lifted towards the indoor direction by the panic bar 130, the latch release part 336 is lifted by the second movable part 176 and the latch hinge 332 is centered. It moves in a direction away from the main frame 110. As the latch release part 336 rotates, the latch part 334 rotates in the opposite direction to the rotation direction of the latch release part 336, and the latch structure formed on the wall is released, allowing the door to be opened. there is. When the external force caused by the panic bar 130 is removed, the door latch 330 is returned to its original position by a spring connecting the door latch 330 and the latch support frame 310.

The door latch 330 can also be unlocked by operating the handle 510. When the unlock head 555 (see FIG. 9) rotates due to the operation of the handle 510, the unlock protrusion 555a pushes the second movable portion 176 of the movable bracket 170, and the lock release portion 336 rotates accordingly. While doing this, the locking portion 334 is released from the latch locking structure on the wall. Therefore, the locked state of the door latch 330 can be released by operating the handle 510.

Meanwhile, the handle unit 500 includes a handle 510 disposed on the outside of the door, a first case 520 supporting the handle 510, and a first case 520 that is coupled to the first case 520 to form a receiving space. Includes 2 cases (530). The handle 510 is a handle for opening and closing the door and is disposed on the outside of the door. One end of the handle 510 is inserted through the handle through hole 522 formed in the first case 520 and connected to the handle operating unit 550, which will be described later.

One end of the handle 510 and the connector 543 of the blocking module 540 are inserted into the handle support portion 532, and the motor 541 of the blocking module 540 is coupled to and supported by the drive support portion 534.

The blocking module 540 includes a motor 541, a connecting link 542, and a connector 543. The blocking module 540 blocks the operation of the handle 510 and the door latch 330 from being linked when access is blocked, and is connected so that the operation of the handle 510 and the door latch 330 are linked when access is permitted. It plays a role.

When an access permit signal is transmitted, the motor 541 rotates in one direction to rotate the connecting link 542 in one direction, and when an access blocking signal is transmitted, the motor 541 rotates in the opposite direction to rotate the connecting link 542 in the other direction.

The connector 543 includes a cylindrical connector housing 543a inserted into the handle support portion 532 of the second case 530, a connecting pin 543b inserted into the inside of the connector housing 543a, and a connector housing 543a. ) includes a connector spring (543c) inserted on the outer peripheral surface of the.

The connector housing 543a has a cylindrical shape, has a groove formed on one radial surface, and is coupled to one end of the handle 510. A groove is also formed on the other radial surface of the connector housing 543a, and the connecting pin 543b is inserted into this groove. One end of the handle 510 and one end of the connecting pin 543b are formed in a hexahedral shape, and the groove is also formed in a corresponding shape, so that the handle 510 and the connecting pin 543b are not rotated arbitrarily when combined.

One end of the connecting pin 543b is inserted into the connector housing 543a, and the other end is exposed to the outside of the connector housing 543a. The externally exposed portion of the connector housing 543a is the portion pressed by the pressing portion 542c of the connection link 542.

The connecting pin 543b is pressed from the direction toward the handle 510 toward the door latch 330. At this time, the connecting pin 543b is pushed toward the operating head 553 of the handle operating portion 550 and moves. Additionally, the connecting pin 543b must be able to remain coupled to the connector housing 543a even when moved toward the operating head 553. The reason is that the operation of the handle 510 must be transmitted to the handle operating unit 550 by the connecting pin 543b in the entry permission state. Therefore, the slit formed in the connector housing 543a and the slit 553a formed in the operating head 553 must be formed smaller than the width of the exposed portion of the connecting pin 543b. The connecting pin 543b is returned to its original position by the connector spring 543c when the pressure by the connecting link 542 is released.

As shown in FIG. 9, the connector spring 543c is a coil spring whose one end is fixed inside the connector housing 543a and the other end is fixed to one end of the connecting pin 543b. The connector spring 543c is tensioned when the connecting pin 543b moves toward the operating head 553, and as it is restored, the connecting pin 543b returns to its original position. The operation of the handle 510 is transmitted to the handle operating unit 550 or blocked by the connector 543.

The handle operating unit 550 is connected to or separated from the support housing 551 through which one end of the handle 510 is inserted, the handle return spring 552 for returning the handle 510, and the connector housing 543a. It includes an operating head 553, an operating rod 554 connected to the operating head 553, and an unlock head 555 inserted into the latch support frame 310 while coupled to the operating rod 554. .

The support housing 551 has a shape in which a ring-shaped disk is integrated with a cylindrical shape having a length shorter than that of the connector housing 543a. One end of the handle 510 penetrates the support housing 551 and is inserted into the connector housing 543a. The support housing 551 is fixed to the handle 510 with a fastening member such as a bolt and rotates together when the handle 510 rotates.

The operating head 553 is selectively coupled to the other end of the connector housing 543a facing the support housing 551. The operating head 553 is coupled to the operating rod 554, and the operating rod 554 is connected to the unlock head 555 and coupled to the latch support frame 310. Therefore, when the operating head 553 is not connected to the connector housing 543a, the operating head 553 does not rotate even if the handle 510 and the support housing 551 rotate.

The operating head 553 is coupled to or disengaged from the connector housing 543a by a connecting pin 543b. To this end, the above-described slit 553a is formed on one side of the outer peripheral surface of the operating head 553 in response to the moving position of the connecting pin 543b.

The operating rod 554 is a rectangular parallelepiped-shaped bar that connects the operating head 553 and the unlock head 555. The unlock head 555 is rotated by the operating rod 554 in the same manner as the operating head 553.

The unlock head 555 is inserted into the head support portion 316 of the latch support frame 310 while being coupled to the end of the operating rod 554. The unlock head 555 has a cylindrical shape, and an unlock protrusion 555a is formed to protrude toward the indoor direction. When the unlock head 555 is inserted into the head support part 316, the unlock protrusion 555a is exposed to the outside (indoor direction) of the head support part 316. When the unlock head 555 rotates, the unlock protrusion 555a presses the movable bracket 170 to rotate the door latch 330.

In the panic bar assembly according to the fourth prior art having the above-described configuration, the operation of the main parts in the access permitting or access blocking state is described as follows.

First, when the access is blocked, the operation of the handle 510 is blocked by the blocking module 540 from being transmitted to the door latch 330. At this time, since the pressing portion 542c of the connecting link 542 does not press the connecting pin 543b of the connector 543, the connecting pin 543b is not connected to the operating head 553 and is connected to the connector housing 543a. ) is placed on the side. When the handle 510 is rotated downward from the outside of the door, the support housing 551 and the connector housing 543a rotate together as the handle 510 rotates. However, since the connector housing 543a and the operating head 553 are not connected, the operating head 553 does not rotate. Therefore, even if the handle 510 is manipulated, the door latch 330 is not unlocked and the door remains locked, making access blocking possible.

Next, when the access is permitted, the blocking module 540 is connected to the operating head 553 and the operation of the handle 510 is transmitted to the door latch 330. That is, the motor 541 rotates by an external control signal and the connector housing 543a is connected to the operating head 553. Accordingly, the operation of the handle 510 can be transmitted to the door latch 330. Therefore, when the handle 510 is rotated downward from the outside of the door, the support housing 551 and the connector housing 543a rotate together as the handle 510 rotates. As the connector housing 543a rotates, the operating head 553 rotates together, thereby rotating the operating rod 554 and the unlock head 555 connected to the operating head 553. As the unlock head 555 enters between the second movable part 176 of the movable bracket 170 and the latch support frame 310, the second movable part 176 pushes the unlocking part 336 of the door latch 330. As the latch release part 336 is pushed, the latch part 334 rotates around the latch hinge 332 and is released from the latch structure on the wall, allowing the door to be opened. Therefore, entry and exit through the door becomes possible.

In both cases described above, if the panic bar 130 is pressed from the inside of the door, the door can be opened regardless of whether it is in an access blocking state.

However, in the case of fire doors, they are usually closely attached to the wall or seated in a recessed area inside the wall, but when a fire is detected by a sensor such as smoke, heat, or carbon dioxide, the fire door detaches from the wall and expands, opening the passage. Block it to prevent the fire or smoke from spreading further.

However, in panic bar modules such as the first to fourth prior arts, the handle protrudes from the fire door, and when the inner side of the fire door is directed toward the wall, the handle protrudes outward (towards the passage), thereby improving aesthetics. Not only is it unsightly, but it can cause inconvenience in passing through the passageway or cause safety accidents for pedestrians. Conversely, if the outer side of the fire door faces the wall, especially in the case of embedded fire doors, the fire door may be sunken into the wall in the form of a fire door. Since it is installed on the part, the handle part must be seated further inside than the fire door type, resulting in various unreasonable situations in building construction.

Moreover, all of the above-described second to third prior technologies have limitations in that their structures are too complex and thus impractical.

Meanwhile, recently, a cup-shaped handle (hereinafter referred to as a cup handle) in which the door handle itself is recessed inside the fire door has been used. The simplest cup handle, as shown in Figure 10, has a connecting groove. This is possible only if it is in the '口' shape.

However, the coupling cam groove of the panic bar unit is in the '+' shape as described above, while in the case of the cup holder, the cup handle connecting groove must be in the '口' shape to enable the simplest cup handle, so the existing connector cannot be used. There is a problem that the two cannot be rotationally combined.
