[0023] As illustrated in FIGS. 1 to 7, the fall prevention safety fence according to an embodiment of the present invention is provided with a first door fence (10) and a second door fence (20) so as to be openable and closable at the entrance of the safety fence.

[0024] The first door fence (10) and the second door fence (20) are arranged symmetrically on the left and right sides, and as shown in FIG. 1, they are unfolded horizontally to close the entrance, and as shown in FIG. 2, they are folded vertically to open the entrance.

[0025] More specifically, the first door fence (10) is composed of a fixed support (100), a first horizontal bar (200), a second horizontal bar (300), a moving support (400), an upper fixed cover (500), a lower fixed box (600), and a driving means (700).

[0026] The above fixed support (100) is formed in the shape of a vertically long cylindrical column and is fixed to the floor to function as a support when the first door fence (10) is opened or closed.

[0027] In addition, the fixed support (100) is composed of a fixed plate (110) fixed to the floor, a fixed pipe (120) that is vertically erected on the upper part of the fixed plate (110), and a fixed cover (130) that surrounds the fixed pipe (120).

[0028] The above fixing plate (110) and the above fixing cover (130) are fixedly installed on the floor by means of an anchor and support the above fixing support (100) so as not to tip over.

[0029] The above fixed pipe (120) is made of metal and is erected at the center of the above fixed plate (110) and connected to the above fixed plate (110).

[0030] The above-mentioned fixed cover (130) wraps around the above-mentioned fixed pipe (120), is in the shape of a vertically elongated cylinder, and is made of synthetic resin material.

[0031] On the side of the above-mentioned fixed cover (130), a first joint part (131) and a second joint part (132) are each formed to protrude laterally.

[0032] The first joint part (131) is positioned in the lower part of the fixed cover (130), and the second joint part (132) is positioned spaced apart from the upper part of the first joint part (131).

[0033] In addition, the first joint part (131) is formed to extend laterally longer than the second joint part (132).

[0034] The first horizontal bar (200) is hinge-connected to the first joint part (131), and the second horizontal bar (300) is hinge-connected to the second joint part (132).

[0035] The first horizontal bar (200) is formed in the shape of a long horizontal bar, one end is hinged to the first joint part (131), and the other end is hinged to the moving support (400).

[0036] Specifically, the first horizontal bar (200) is composed of a bar cover (210), a finishing cap (220), a reinforcing tube (230), a first washer (240), and a first hinge bolt (250).

[0037] The above-mentioned rod cover (210) is made of synthetic resin material and is formed with both ends penetrating, and a flat surface (211) is formed on each side.

[0038] The above-mentioned planar portions (211) are arranged parallel to each other and are formed long along the length direction of the rod cover (210).

[0039] The end caps (220) are inserted and mounted at both ends of the above-mentioned cover (210).

[0040] The above end cap (220) blocks foreign matter from entering the interior of the rod cover (210), supports the end of the rod cover (210) to increase strength, and improves the appearance.

[0041] The reinforcing tube (230) is formed in the shape of a long rectangular metal tube and is inserted into the interior of the rod cover (210) and positioned to be in contact with the flat portion (211).

[0042] The first washer (240) is positioned at the location where the first crossbar (200) is hinge-connected to the first joint part (131) and is inserted into the flat part (211).

[0043] The first hinge bolt (250) passes through the rod cover (210), the first washer (240), and the reinforcing tube (230) to hinge-connect the first horizontal rod (200) to the first joint part (131).

[0044] Here, the first washer (240) placed on the flat portion (211) has one side in contact with the reinforcing tube (230) and the other side in contact with the first joint portion (131), thereby smoothing the rotation of the first crossbar (200) and preventing wear.

[0045] The second crossbar (300) is configured in the same way as the first crossbar (200), and one end is hinge-connected to the second joint part (132). Since the structure in which the second crossbar (300) is hinge-connected to the second joint part (132) is the same as that of the first crossbar (200), a detailed description is omitted.

[0047] Meanwhile, the moving support (400) is formed in the shape of a long rod, connects the other end of the first horizontal bar (200) and the other end of the second horizontal bar (300), and its lower end is supported on the floor.

[0048] Specifically, on the side of the moving support (400), a third joint part (410) and a fourth joint part (420) are formed protruding outwardly and spaced apart from each other.

[0049] Here, the length of the fourth joint part (420) is formed to protrude longer than the length of the third joint part (410).

[0050] The other end of the first horizontal bar (200) is hinge-connected to the third joint (410), and the other end of the second horizontal bar (300) is hinge-connected to the fourth joint (420).

[0051] The structure in which the other end of the first horizontal bar (200) is hinge-connected to the third joint part (410) and the structure in which the other end of the second horizontal bar (300) is hinge-connected to the fourth joint part (420) are identical to the structure in which one end of the first horizontal bar (200) and the first joint part (131) are connected, so a detailed explanation is omitted.

[0053] Meanwhile, the length of the first joint part (131) is formed to protrude longer than the length of the second joint part (132), and the length of the fourth joint part (420) is formed to protrude longer than the length of the third joint part (410).

[0054] Therefore, when the entrance of the safety fence is opened, the first horizontal bar (200), the second horizontal bar (300), and the moving support (400) are folded vertically without overlapping each other and are arranged side by side adjacent to each other on the side of the fixed support (100).

[0055] In this way, by making the hinge connection positions of the first horizontal bar (200) and the second horizontal bar (300) different, the first horizontal bar (200) and the second horizontal bar (300) do not overlap each other when the doorway is opened, thereby ensuring safe operation and providing the effect of improving durability.

[0057] In addition, a rubber cover (430) is installed on the bottom of the moving support (400).

[0058] The rubber cover (430) absorbs shock and vibration caused by the load of the moving support (400) when the lower end of the moving support (400) is inserted into the lower fixing box (600) described later, thereby improving the durability of the connection part of the first horizontal bar (200) and the second horizontal bar (300) and providing the effect of improving safety.

[0060] Meanwhile, the upper fixing cover (500) is mounted on the upper part of the moving support (400), and has two insertion grooves formed open at the bottom, connecting and fixing two moving supports (400) arranged adjacent to each other.

[0061] That is, when the upper fixed cover (500) is closed, it connects the moving support (400) of the first fence door (10) and the moving support (400) of the second fence door (20) that are positioned adjacent to each other.

[0062] At this time, the upper portions of the two moving supports (400) are inserted into the insertion grooves of the upper fixed cover (500) to prevent the first fence door (10) and the second fence door (20) from moving back and forth or the gap from opening.

[0064] The lower fixed box (600) is fixedly installed on the floor where the moving support (400) is placed, and two seating grooves are formed openly on the top.

[0065] The lower ends of the moving support (400) of the first fence door (10) and the moving support (400) of the second fence door (20) are inserted into the above-mentioned mounting groove, thereby preventing the first fence door (10) and the second fence door (20) from easily opening or moving, thereby improving safety and durability and providing the effect of preventing damage caused by external factors.

[0067] Meanwhile, the above driving means (700) operates to open and close the safety fence and is composed of a fixing bracket (710), a gas lift (720), a second hinge bolt (730), a second washer (740), and a third washer (750).

[0068] The above-mentioned fixed bracket (710) is fixedly installed on the floor adjacent to the above-mentioned fixed support (100), and installation portions (711) are formed protruding upward at both ends.

[0069] Two gas lifts (720) are installed on the fixed bracket (710), one end is hinged to the installation part (711) of the fixed bracket (710), and the other end is hinged to the second crossbar (300).

[0070] Additionally, the second washer (740) and the third washer (750) are placed on both sides of the gas lift (720) to reduce vibration and friction when the gas lift (720) rotates around the second hinge bolt (730).

[0071] As the other end of the gas lift (720) extends, the first crossbar (200) rotates around the end, and at this time, the second crossbar (300) and the moving support (400) rotate upward in conjunction, and the first crossbar (200), the second crossbar (300), and the moving support (400) are arranged to be folded on the side of the fixed support (100) to open the entrance.

[0073] The fall prevention safety fence according to the embodiment of the present invention, configured as above, provides the effect of preventing a fall accident by blocking the entrance of the safety fence during work, and provides the effect of allowing convenient use of the entrance by causing the first fence door (10) and the second fence door (20) to rotate in opposite directions to open the entrance by means of the driving means (700).

[0075] The present invention is not limited thereto and may be modified in various forms by those skilled in the art without departing from the spirit and scope of the following appended claims; therefore, such modifications should be interpreted as being within the scope of the present invention.
