Through the regulation unit having such a configuration, the safety bar 200 may have one end inserted into the regulation plate 311 to restrict one-way movement to a position outside the regulation plate 311.

In addition, the movement of the coupling housing 320 is restricted by the restriction pin 312 when the safety bar 200 whose position is fixed by the regulation plate 311 moves in the other direction to be removed from the regulation plate 311. It is possible to regulate that the safety bar 200 is completely deviated from the opened other direction of the main housing 320.

The first hook hole 313 is a configuration in which the locking protrusion 322 of the elastic member 330 to be described below is inserted, and the main housing 310 is closed in a direction perpendicular to the longitudinal direction of the safety bar 200. It may be formed through both sides.

The elastic member 330 is configured to fix the coupling housing 320 at a specific position of the main housing 310 when the coupling housing 320 is moved inside the main housing 310. At this time, the specific position may correspond to a position where one end of the safety bar 200 is inserted into the regulation plate 311.

Specifically, the elastic member 330 may be composed of a plate spring having a pair of free ends 331, and the locking projections 332 to be described below are selectively inserted in the first hook hole 313. It is desirable to have elasticity that can be lost.

In the present invention, although the elastic member 330 is formed to have a U-shape, it is obvious that the central portion can be deformed into various shapes such that the central portion is bent to have both ends.

And the locking projection 332 is a configuration for the operator to press the free end 331 of the elastic member 330, the free end 331 is formed to protrude in opposite directions to each other, the first hook hole 313 And a second hook hole 321.

At this time, the locking protrusion 332 has a length that can be fixed to the first hook hole 313, the second hook hole 321 is fixed.

Finally, the hook rod 340 is configured to penetrate the first through hole 210 and the insertion slit 131, one end of the hook rod 340 is connected to the closed one surface of the coupling housing 320, and the other end A predetermined length may be formed toward the first through hole 210.

After the 340) is inserted through the first through hole 210, it serves to prevent it from randomly exiting.

Hereinafter, the assembled state of the prefabricated railing including the safety bar of the present invention having the above configuration will be described with reference to FIGS. 2 to 8.

First, FIG. 2 is an operation state diagram for explaining a first assembly state of a prefabricated railing including a safety bar according to an embodiment of the present invention, and FIG. 3 is a first of prefabricated railing including a safety bar according to an embodiment of the present invention. It is an operation sectional view for explaining the assembled state.

The first assembly state shown in FIGS. 2 and 3 is a view showing a state in which a prefabricated railing including a safety bar according to the present invention is completely assembled.

As shown in FIG. 2, the safety bar 200 is penetrated through the hook rod 340 and the coupling of the coupling assembly 300 is fixed in the state where the coupling to the fixing bracket 100 is completed.

At this time, it can be seen that the hook rod 340 is inserted forward toward the insertion slit 131 and is fixed so that it cannot be pulled backward by the stopper 341.

And it can be seen that the possibility of moving upward along the insertion slit 131 by the position fixing portion 132 of the hook rod 340 in which the front and rear movements are fixed is excluded.

At this time, the safety bar 200, which has been jammed in the fixing bracket 100, is inserted into the regulation plate 311 to become the primary fixing (see FIG. 2).

Then, the locking protrusion 332 of the elastic member 330 penetrates through the first hook hole 313 of the main housing 310 and the second hook hole 321 of the coupling housing 320 to the regulation plate 311. It can be seen that the coupling housing 320 to which the safety bar 200 in one end is inserted is secondarily fixed to the main housing 310 (see FIG. 3), so that the rotation of the safety bar 200 is intermittent.

And Figure 4 is an operational state diagram for explaining a second assembly state of the prefabricated railing comprising a safety bar according to an embodiment of the present invention, Figure 5 is a second assembly of a prefabricated railing including a safety bar according to an embodiment of the present invention It is an operation sectional view for explaining a state.

The second assembly state shown in FIGS. 4 and 5 is a view showing a state in which the prefabricated railing including the safety bar according to the present invention is unfixed.

As shown in FIG. 4, the locking protrusion 332 is released from the first hook hole 313 to release the fixing of the coupling housing 320.

Accordingly, when the fixing of the coupling from the main housing 310 is released from the coupling housing 320, one end of the safety bar 200 can be removed from the regulating plate 311.

At this time, to look at the deformation state of the elastic member 330 in detail through FIG. 5, the engaging projection 320 is removed from the first hook hole 313 by external pressure and the coupling housing 320 is regulated pin 312. ) As it moves in the direction, it can be seen that the coupling housing 320 is unfixed from the main housing 310 while the free end 311 remains pressed in the main housing 310.

Finally, FIGS. 6 and 7 are operation state diagrams for explaining a third assembly state of a prefabricated railing including a safety bar according to an embodiment of the present invention, and FIG. 8 is a prefabricated structure including a safety bar according to an embodiment of the present invention. It is an operation sectional view for explaining the third assembly state of the railing.

6 to 8 is a view showing a state in which the fixing of the hook rod 340 is released from the fixing bracket 100.

As shown in FIG. 6, as the coupling housing 320 is released from the main housing 310 and the safety bar 200 is removed from the regulation plate 311, the hook rod 340 has a first through hole ( 210) It can be seen that free rotation is possible on the inner peripheral surface.

In other words, as the main housing 310 is rotated 90 degrees downward, the stopper 341 is rotated in the same direction as the insertion slit 131.

However, it is obvious that the coupling housing 320 can be rotated 180 degrees in both directions based on one end of the safety bar 200 when the main housing 310 is fixed.

That is, in FIG. 6, the end of the stopper 341 is rotated to face downward in the state facing to the right, but it is possible to rotate so that the end of the stopper 341 faces upward in the state to the right.

As a result, it can be seen that as the stopper 341 is positioned on the same line as the insertion slit 131, the hook rod 340 can exit the insertion slit 131 (see FIG. 7).

At this time, looking at the deformation state of the elastic member 330 in detail through FIG. 8, while the free end 311 is maintained in a compressed state inside the main housing 310, the coupling housing 320 is the main housing 310. ), The hook rod 340 is rotated 360 degrees on the inner circumferential surface of the first through hole 210.

Therefore, it can be seen that the coupling housing 320 is rotated in the vertical direction with the safety bar 200 together with the main housing 310, and the stopper 341 can be positioned on the same line as the insertion slit 131. .

Hereinafter, a state of application of a workshop of a prefabricated railing including a safety bar of the present invention capable of implementing the above-described operating state will be described with reference to FIG. 9.
