Panic Device Having an Easy-to-Assemble Three-Point Fastening Structure

Abstract

The present invention relates to a panic device configured such that a horizontal locking latch and a vertical locking latch operate simultaneously in conjunction with each other by the pressing operation of a push bar. To this end, a rotary connector is configured to include a horizontal lever and a rotary lever, and converts the linear motion of the push bar into rotational motion and transmits it to the horizontal locking latch and the vertical locking latch. In addition, by enabling the simultaneous operation of the upper and lower vertical locking latches through a combined structure of a vertical rod, a slide, and a pin, it is possible to simplify the structure, improve assembly, and enhance durability. In particular, by configuring the upper vertical locking latch and the lower vertical locking latch to be simultaneously pulled toward the rotary connector by a rotary lever, simultaneous release of the upper and lower latches is possible without a separate complex link structure.

Description

Technology Field

[0001] The present invention relates to a panic device, and more specifically, to a device installed on a door that can open the door in the event of an emergency disaster. Background Technology

[0002] Conventional panic devices used multiple links and complex connection structures to transmit the operating force of the push bar to horizontal latches and vertical latches located above and below, respectively, which resulted in problems of reduced assembly and durability due to the increased number of parts.

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The following description and the accompanying drawings are provided for the general understanding of the present invention and are not intended to limit the technical scope of the present invention. Furthermore, detailed descriptions of known configurations and functions that could unnecessarily obscure the essence of the present invention will be omitted.

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, the technical concept of the present invention is not limited to the following embodiments and may be implemented in various modified forms.

[0021] A panic device according to an embodiment of the present invention is installed on the indoor side of a door and is configured so that, in the event of a fire or emergency, the user can open the door by simultaneously releasing the horizontal locking latch (50) and the vertical locking latch (60) simply by pressing the push bar (20).

[0022] The main frame (10) is a structure that supports the entire device and can be installed longitudinally on one side of the door. The push bar (20) is installed on the front of the main frame (10) and can be configured to move inward by pressing action by a user.

[0023] The head frame (30) is coupled to the end of the main frame (10), and can be installed so that some components of a rotary connector (40), a horizontal locking latch (50), and a vertical locking latch (60) are connected inside.

[0024] The rotary connector (40) is installed on the head frame (30) and is configured to transmit operating force to the locking device while rotating in conjunction with the linear movement of the push bar (20), and may include a horizontal lever (41) and a rotary lever (42).

[0025] The horizontal lever (41) is configured such that its middle portion is axially coupled to the head frame (30), one side is connected to the push bar (20), and the other side contacts the horizontal locking latch (50). Accordingly, when a user presses the push bar (20), the horizontal lever (41) rotates, thereby rotating the horizontal locking latch (50) to release the lock.

[0026] The rotation lever (42) can be positioned vertically above and below the head frame (30), respectively, and is installed so as to be rotatable by connecting the middle portion to an axis. One side of the rotation lever (42) is linked to the rotation of the horizontal locking latch (50), and the other side is connected to a vertical rod to operate the vertical locking latch (60) up and down.

[0027] Accordingly, when the push bar (20) is pressed, the horizontal locking latch (50) rotates and the rotating lever (42) rotates simultaneously, thereby tensioning the vertical locking latch (60) located above and below, so that the door lock can be released all at once.

[0028] The horizontal locking latch (50) may include a shaft connecting part (51), a latch (52), a plate (53), and a shaft part (54).

[0029] The shaft connecting part (51) is rotatably connected to the head frame (30) and can be restored to its original position by an elastic member. A latch (52) is formed connected to one side of the shaft connecting part (51) and is engaged with a locking part of the door frame to lock the door. Here, a torque spring is connected to the shaft connecting part (51) so that it returns to its original state when the pressure is released.

[0030] The plate (53) is formed on the other side of the shaft connection part (51) and can come into contact with the end of the horizontal lever (41), and rotates by being pressed by the rotation of the horizontal lever (41). The shaft part (54) is formed protruding from both sides of the plate (53) and is axially coupled with the rotation lever (42), and can be configured to transmit the rotational force of the horizontal locking latch (50) to the rotation lever (42).

[0031] Meanwhile, a bolt (43) may be connected to the end of the rotating lever (42), a vertical rod (44) may be connected to the bolt (43), and vertical locking latches (60) located above and below may be connected to the other side of the vertical rod (44).

[0032] The vertical locking latch (60) may include a body (61), a locking latch (62), a slide (63), and a pin (64).

[0033] The locking latch (62) is rotatably installed on the upper part of the body (61) and can be caught on a door or a floor / ceiling side catch. The slide (63) is installed to be movable in the vertical direction on the body (61) and can be connected to a vertical rod (44).

[0034] A groove (44-1) may be formed on the outer surface of the vertical rod (44), and a pin (64) is coupled to the slide (63) and inserted into the groove (44-1). Accordingly, when the vertical rod (44) moves up and down, the slide (63) moves in conjunction, and the locking latch (62) rotates, thereby performing a locking or unlocking operation.

[0035] That is, when the vertical rod (44) rises, the locking latch (62) rotates to move to the locked position, and when the vertical rod (44) descends, the locking latch (62) rotates in the opposite direction so that the lock can be released.

[0036] The rotation lever (42) can be configured so that one end and the other end move in opposite directions relative to the center of rotation, and accordingly, when the rotation lever (42) is rotated, both the upper vertical rod (44) and the lower vertical rod (44) connected thereto perform a tension operation in the direction of the rotation connector (40) to perform an opening operation.

[0037] That is, when the user presses the push bar (20), the horizontal lever (41) rotates, and as the rotation lever (42) linked thereto rotates, the upper vertical rod (44) is tensioned downward and the lower vertical rod (44) is tensioned upward. In particular, since the vertical locking latch (60) is simultaneously released by the tension, the connection structure that engages with the latches located above and below can be simplified.

[0038] As can be seen from the above, the present invention is based on a basic technical concept, and within the scope of such basic concept of the present invention, it is obvious that many other variations are possible for those skilled in the art. Explanation of the symbols
