The guide protrusion 322 has a shape corresponding to the guide rail 314 and is configured to allow the coupling housing 320 to slide and move inside the main housing 310.

The elastic member 330 is a component for fixing 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. In this case, 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 protrusion 332 to be described below is selectively inserted in the first hook hole 313 It is desirable to have elasticity that can be worn.

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

And the locking protrusion 332 is a configuration for the operator to press the free end portion 331 of the elastic member 330, the free end portion 331 is formed to protrude in opposite directions to each other, the first hook hole 313 And it may be formed to hang on the second hanging hole 321.

At this time, the locking protrusion 332 has a length in which the first hook hole 313 is selectively hooked, and the second hook hole 321 is fixed to the hook.

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

Meanwhile, a stopper 341 protruding in a direction orthogonal to the longitudinal direction of the hanging rod 340 may be provided on one side of the hanging rod 340.

The stopper 341 is inserted into the first through hole 210 together with the hanging rod 340 and then rotated at a certain angle so as not to match the shape of the first through hole 210. After 340 is inserted through the first through hole 210, it serves to prevent it from being arbitrarily removed.

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

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

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

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

In addition, it can be seen that the possibility of moving upwards along the insertion slit 131 is excluded by the position fixing unit 132 of the hook rod 340 to which the front and rear movements are fixed.

At this time, the safety bar 200, which has been engaged with the fixing bracket 100, is inserted into the regulation plate 311 to be first fixed (see FIG. 2).

And the locking protrusion 332 of the elastic member 330 passes through the first hooking hole 313 of the main housing 310 and the second hooking hole 321 of the coupling housing 320 to the regulation plate 311 It can be seen that the rotation of the safety bar 200 is interrupted by the coupling housing 320 to which the safety bar 200 with one end inserted therein is fixed secondarily to the main housing 310 (see FIG. 3 ).

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

The second assembled state shown in FIGS. 4 and 5 is a view showing a state in which the assembled handrail including the safety bar according to the present invention is released from the assembled state.

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

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

At this time, looking at the deformed state of the elastic member 330 in detail through FIG. 5, the locking protrusion 322 is removed from the first hook hole 313 due to external pressure, and the coupling housing 320 is removed from the regulation pin 312. It can be seen that the coupling housing 320 is released from the main housing 310 as the free end 311 is kept pressed inside the main housing 310 as it moves in the) direction.

Finally, Figures 6 and 7 are operational state diagrams for explaining the third assembly state of the assembly type handrail including the safety bar according to an embodiment of the present invention, Figure 8 is an assembly type including a safety bar according to an embodiment of the present invention It is an operation sectional view for explaining the 3rd assembly state of a railing.

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 hanging rod 340 becomes the 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 when the coupling housing 320 is released from the main housing 310, it is possible to rotate 180 degrees in both directions based on one end of the safety bar 200.

That is, in FIG. 6, the end of the stopper 341 is rotated to face the lower side from the right side, but the end of the stopper 341 can be rotated to the upper side while the end faces the right side.

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

At this time, looking at the deformed state of the elastic member 330 in detail through FIG. 8, while the free end 311 is kept pressed inside the main housing 310, the coupling housing 320 is the main housing 310 ) Is fixed from the first through hole 210 in the inner circumferential surface of the hook rod 340 is rotated 360 degrees.

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

Hereinafter, an implementation state of the workshop application of the prefabricated handrail including the safety bar of the present invention capable of implementing the above operation state will be described with reference to FIG. 9.
