[0038] As an example, in FIGS. 1 and 2, the catch (30) is shown as being integrally folded to form a right angle with the insert plate (10).

[0039] Meanwhile, the insert plate (10) and the catch (30) are arranged at one location on one end of the locker plate (20) as shown in FIG. 4, or are installed at two locations in opposite directions on both ends of the locker plate (20) as shown in FIG. 5, so that they can be applied to both left and right opening type doors.

[0040] And, when the insert plate (10) and the catch (30) are applied as a pair to both ends of the locker plate (20), a pair of stop holders (40) described later are respectively arranged at positions corresponding to the insert plate (10), and the pair of stop holders (40) are respectively arranged at different intervals from the locker plate (20), so that one of the pair of stop holders (40) can be selectively applied in response to the door thickness, thereby adjusting the mounting position of the stopper member (50) described later.

[0041] In addition, the stop holder (40) according to the present invention is formed through the rocker plate (20).

[0042] In addition, the stopper member (50) according to the present invention is provided with a stop pin (51) formed to be fastened to the stop holder (40), and is provided to restrain the door (1) while being mounted on the locker plate (20) through the stop pin (51).

[0043] At this time, the stop pin (51) includes a shaft (51a) that is installed on a stopper member (50) and fitted into a stop holder (40), and an extension piece (51b) that is formed to be extended at the end of the shaft (51a) and is restrained on the back surface of the stopper member (50).

[0044] In addition, the stop holder (40) includes an entry hole (41) through which an extension piece (51b) is inserted, and an insertion hole (42) connected to the entry hole (41) and formed in a size reduced compared to the entry hole (41) to be engaged with and connected to the shaft (51a), and the insertion hole (42) is formed in the opposite direction of the insert plate (10) with the entry hole (41) as the center.

[0045] When the extension piece (51b) of the above stop pin (51) is inserted through the entry hole (41) of the stop holder (40), and the shaft (51a) of the stop pin (51) is fitted into the fitting hole (42) of the stop holder (40), the extension piece (51b) is held in a state of being caught on the back surface of the rocker plate (20) to support the stopper member (50).

[0046] As an example, as shown in FIG. 4 (a) and FIG. 5 (a), the stop holders (40) are arranged in multiple spaces, and each stop holder (40) is arranged at a different distance from the catch (30), so that the installation interval of the stopper member (50) can be adjusted in accordance with the specifications of the door leaf (1).

[0047] As another embodiment, as shown in FIG. 4 (b) and FIG. 5 (b), the stop holder (40) includes an entry hole (41) provided for inserting an expansion piece (51b), an inclined rail (43) formed with a long hole having a diameter reduced compared to the entry hole (41) and configured to accommodate a shaft (51a) and having an angle of inclination that inclines downward toward the engaging piece (30), and an insertion hole (42) spaced apart from the inclined rail (43) and formed with a size reduced compared to the entry hole (41) to engage and engage with the shaft (51a), and the insertion hole (42) is formed in a direction opposite to the insert plate (10) based on the inclined rail (43).

[0048] And, when the shaft (51a) moves downward along the inclined rail (43), the stopper member (50) moves inclinedly so that the shaft (51a) is engaged with the fitting hole (42) and restrained at the point where it comes into contact with the door leaf (1).

[0049] In this way, as the shaft (51a) moves at an inclined angle along the inclined rail (43), the gap between the door (1) and the stopper member (50) is adjusted, thereby providing versatility in applying the stopper member (50) to door members (1) of various thicknesses.

[0050] At this time, an intrusion detection unit (60) is installed on the stopper member (50) and detects the operating force in the opening direction of the door (1).

[0051] The above intrusion detection unit (60) includes a sensor (61) that is exposed to the outer surface of the stopper member (50) and detects the operating force in the opening direction of the door (1), and a notification module (62) that is operated by a detection signal from the sensor (61) and is provided to output one or more notification signals among a warning sound, a warning light, vibration, and message transmission between mobile terminals using short-range communication.

[0052] Looking at the usage state of the intrusion detection unit (60) through Fig. 7, the door (1) is opened, and as shown in Fig. 7 (a), the catch (30) is inserted into the latch hole (2b) of the striker (2a), and the door (1) is closed to restrain the insert plate (10) in the gap space (3), and as shown in Fig. 7 (b), the stop pin (51) of the stopper member (50) is fastened to the stop holder (40) of the locker plate (20), so that the door (1) is restricted from moving in the opening direction by the stopper member (50).
