[0027] The first plate may be provided with a plurality of through holes so that a fixing means, such as a bolt, can be assembled.

[0028] This first plate can be formed in a 'U' shape so that the door leaf can be easily separated from the door frame when the door is closed.

[0029] In this case, the upper knuckle (110) is provided at one end of the first plate as shown in FIGS. 2 and 3, and the lower knuckle (120) is provided at the other end of the first plate opposite to the one end.

[0030] The upper knuckle (110) is formed to have a tubular structure and provides an insertion space for the assembly pin (300).

[0031] The lower knuckle (120) is formed to have a tubular structure and provides an insertion space for the assembly pin (300).

[0032] If necessary, the first leaf (100) may be configured to further include a first seating ring (130) as shown in FIG. 3.

[0033] The first seating ring (130) is provided on the inner surface of the upper knuckle (110) and is formed to have a tubular structure, and a recessed section (132) in the direction of the lower knuckle is formed so that the insertion depth of the rotation shaft (320) changes when the rotation shaft (320) inserted from the upper knuckle (110) to the lower knuckle (120) as shown in FIG. 3 is rotated.

[0034] This first seating ring (130) is formed to have a length shorter than the length of the upper knuckle (110) so that a space is provided for the contact ring (340), which will be described later, to be inserted into the interior of the upper knuckle (110), and an inner diameter corresponding to the outer diameter of the rotation shaft (320) is formed to provide a passage into which the rotation shaft (320) can be inserted and a space in which the contact ring (340) can be seated. For example, the first seating ring (130) is formed to have an inner diameter equal to the outer diameter of the rotation shaft (320), or is formed to have an inner diameter expanded by about 1 mm to 5 mm compared to the outer diameter of the rotation shaft (320) so that a clearance space is formed.

[0035] Additionally, the first leaf (100) may be configured to further include a second seating ring (140) as shown in FIG. 4.

[0036] The second settling ring (140) is provided on the inner surface of the lower knuckle (120) and is formed to have a tubular structure, and a recessed section (142) in the direction of the upper knuckle is formed so that the insertion depth of the rotation shaft (320) changes when the rotation shaft (320) inserted from the lower knuckle (120) to the upper knuckle (110) as shown in FIG. 3 is rotated.

[0037] This second seating ring (140) is formed to have a length shorter than the length of the lower knuckle (120) so that a space is provided for the sealing ring (340) to be inserted into the interior of the lower knuckle (120), and an inner diameter corresponding to the outer diameter of the rotation shaft (320) is formed to provide a passage into which the rotation shaft (320) can be inserted and a space in which the sealing ring (340) can be seated. For example, the second seating ring (140) is formed to have an inner diameter equal to the outer diameter of the rotation shaft (320), or is formed to have an inner diameter expanded by about 1 mm to 5 mm compared to the outer diameter of the rotation shaft (320) so that a clearance space is formed.

[0039] Referring to FIG. 2, the emergency separation hinge according to the present invention includes a second leaf (200).

[0040] The second leaf (200) is installed in the remaining place between the door and the door frame where the first leaf (100) is not installed, so as to connect the door and the door frame, and is equipped with a central knuckle (210) positioned between the upper knuckle (110) and the lower knuckle (120).

[0041] Specifically, the second leaf (200) is configured to include a second plate having a flat plate structure as shown in FIG. 2, and a central knuckle (210) provided on one side of the upper part of the second plate.

[0042] The second plate may be provided with a plurality of through holes so that a fixing means, such as a bolt, can be assembled.

[0043] The second plate above may be formed to have a rectangular structure corresponding to the empty space of the first plate as shown in FIG. 2 so that the door leaf can be easily separated from the door frame when the door is closed.

[0044] In this case, a central knuckle (210) is provided on the side of the second plate. The central knuckle (210) is formed to have a tubular structure and provides an insertion space for the assembly pin (300). This central knuckle provides the function of allowing the second plate to rotate around the inserted rotation axis (320).

[0045] In a specific embodiment, the central knuckle (210) according to the present invention may be formed to have an inner diameter equal to the inner diameter of the first seating ring (130) and the second seating ring (140) so as to stably support the rotation axis (320) of the assembly pin (300) without shaking.

[0047] FIG. 5 is a perspective view illustrating an assembly pin according to one embodiment of the present invention.

[0048] Referring to FIGS. 2 and FIGS. 5, the emergency separation hinge according to the present invention includes an assembly pin (300).

[0049] The assembly pin (300) is configured to provide a central axis to the first leaf (100) and the second leaf (200) so that the first leaf (100) and the second leaf (200) can move around a single central axis, and comprises a locking unit (310), a rotation axis (320), and a first magnet (330).

[0050] The above-mentioned locking unit (310) is formed at the end of the assembly pin (300) and has an outer diameter that is expanded beyond the inner diameter of the upper knuckle (110) and the lower knuckle (120) so that the assembly pin (300) cannot pass through the upper knuckle (110) or the lower knuckle (120).

[0051] More specifically, the locking unit (310) may be composed of a disc (312) having an outer diameter that is expanded beyond the inner diameter of the upper knuckle (110) and lower knuckle (120) as shown in FIG. 2, and a handle plate (314) provided on the disc (312) and having a hole formed therein.

[0052] In this way, since the catch unit (310) has a hole formed in the handle plate (314), it can prevent slipping when the user grips the handle plate (314), and since a string can be connected to the hole, the assembly pin (300) can be separated from the emergency separation hinge by pulling the string even from a position away from the emergency separation hinge.

[0053] The above-mentioned rotating shaft (320) is formed to protrude from the locking unit (310) and is assembled to the upper knuckle (110), the central knuckle (210), and the lower knuckle (120), and is formed to have a rod structure.

[0054] This rotation axis (320) can be formed to have an outer diameter corresponding to the inner diameter of the first and second seating rings (130, 140) so that the first and second leaves can be rotated without shaking after being inserted into the first and second seating rings (130, 140).

[0055] Additionally, the rotation axis (320) may have a magnet insertion groove (322) having a column structure such as a cylinder formed at the end so that the first magnet (330) can be fitted and assembled at the end located opposite the direction of the locking unit (310).

[0056] The first magnet (330) is provided at the end of the rotation shaft (320) and provides a function of maintaining the state in which the assembly pin (300) is assembled to the first leaf (100) and the second leaf (200) using magnetic force. This first magnet (330) is inserted into the magnet insertion groove (322) of the rotation shaft (320) and then attached to the rotation shaft (320) through an adhesive or the like.

[0057] If necessary, the assembly pin (300) may further include a contact ring (340) provided on the outer surface of one end of the rotating shaft (320) connected to the locking unit (310) as shown in FIG. 5. This contact ring (340) is in close contact with the recessed section (132) of the first seating ring (130) or the recessed section (142) of the second seating ring (140), and when the rotating shaft (320) is rotated, it moves away from the recessed section, thereby forming a protruding section (342) that separates the first magnet (330) from the second magnet (420).

[0058] Neodymium magnets can be used for these first magnet (330) and second magnet (420).

[0060] Referring to FIG. 2, the emergency separation hinge according to the present invention includes a fastening part (400).

[0061] The above-mentioned fastening part (400) is attached to the end of the assembly pin (300) so that the assembly pin (300) penetrating the upper knuckle (110), the central knuckle (210), and the lower knuckle (120) is not separated from the first leaf (100) and the second leaf (200), and is configured to include a cover unit (410) and a second magnet (420).

[0062] The above cover unit (410) acts as a stopper to prevent the upper knuckle (110) or lower knuckle (120) from passing through while attached to the rotation axis (320), and has an outer diameter that is expanded compared to the inner diameter of the upper knuckle (110) and lower knuckle (120). This cover unit (410) is formed to have a column structure such as a cylinder, and is provided with a disc-shaped recessed groove on its surface so that the second magnet (420) can be inserted.

[0063] The second magnet (420) is provided in the cover unit (410), and an attractive force acts between it and the first magnet (330) provided in the magnet insertion groove (322) of the rotation axis (320), and when in close contact with the first magnet (330), it maintains a stably attached state. After being inserted into the disc-shaped recessed groove, this second magnet (420) is attached to the cover unit (410) through an adhesive or the like.

[0065] Referring to FIG. 2, the emergency separation hinge according to the present invention may further include a first O-ring (510) and a second O-ring (520).

[0066] The first O-ring (510) is provided between the upper knuckle and the central knuckle, and reduces the frictional force generated between the upper knuckle (110) and the central knuckle (210), thereby helping the first leaf (100) and the second leaf (200) to rotate smoothly.

[0067] This first O-ring (510) has an inner diameter corresponding to the outer diameter of the rotation shaft (320) so that the rotation shaft (320) can be inserted.

[0068] The second O-ring (520) is provided between the lower knuckle (120) and the central knuckle (210), and helps to reduce the frictional force generated between the lower knuckle (120) and the central knuckle (210), thereby enabling the first leaf (100) and the second leaf (200) to rotate smoothly.

[0069] Additionally, the second O-ring (520) has an inner diameter corresponding to the outer diameter of the rotation shaft (320) so that the rotation shaft (320) can be inserted.

[0070] In addition, the second O-ring (520) helps the door and the door frame to be easily separated from each other after removing the rotation shaft (320).

[0072] Figures 6 and 7 are photographs showing the assembly pin of the present invention, in which the depth of insertion changes when rotated.

[0073] In the assembly pin (300) according to the present invention, as shown in FIG. 6, when the protruding portion (342) of the contact ring (340) is in contact with the recessed portion (132) of the first seating ring (130) or the recessed portion (142) of the second seating ring (140), the first magnet (330) comes into contact with the second magnet (420) of the fastening portion (400). At this time, the second magnet (420) provides magnetic force to the first magnet (330) to prevent the assembly pin (300) from detaching from the first and second leaves.

[0074] Additionally, when the user rotates the assembly pin (300) at a predetermined angle as shown in Fig. 7, the protruding section (342) of the contact ring (340) moves away from the recessed section (132) of the first seating ring (130) or the recessed section (142) of the second seating ring (140), thereby forming a gap between the contact ring (340) and the first and second seating rings (130, 140).

[0075] In this way, when a gap is formed between the contact ring (340) and the first and second seating rings (130, 140), the first magnet (330) is separated from the second magnet (420), and the magnetic force acting between the first magnet (330) and the second magnet (420) is weakened, so that even if an elderly person or a child pulls the assembly pin (300), the assembly pin (300) can be easily separated from the first and second rings.

[0077] FIGS. 8 and FIGS. 9 are photographs showing the assembly direction of an assembly pin according to the present invention.

[0078] The assembly pin (300) according to the present invention may be inserted into the upper knuckle (110) and assembled as shown in FIG. 8, or inserted into the lower knuckle (120) and assembled as shown in FIG. 9.

[0079] In this way, the emergency separation hinge according to the present invention can freely change the installation direction of the assembly pin (300) so that the assembly pin (300) can be pulled downward if there is insufficient space in the direction of pulling the assembly pin (300) upward depending on the installation environment. In other words, the assembly direction of the assembly pin (300) is not limited in the present invention, and depending on the installation environment, the assembly pin (300) may be assembled so that it is first inserted into the upper knuckle (110), or the assembly pin (300) may be assembled so that it is first inserted into the lower knuckle (120).

[0081] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
