Description

Safety Fence for Preventing Falling The present disclosure relates to safety fences. In particular, it relates to safety fences installed for the walking and work of workers in buildings, logistics facilities, factories, etc., or safety fences installed at entrances. Typically, scaffolding and safety fences are installed at factories, construction sites, or cargo transfer areas to facilitate workers' movement and operations. At construction sites, scaffolding is installed along walls connected to supports to allow workers to work at high positions, and safety fences are installed along the scaffolding to prevent falls. In addition, scaffolding and safety fences are installed in logistics warehouses and similar facilities to ensure the safety of workers during loading and unloading operations. However, conventional safety fences are inevitably configured with open entrances in certain sections to facilitate passage or the loading and unloading of goods, and many fall accidents are occurring at these entrances due to carelessness during work. FIG. 1 is a front view of a fall prevention safety fence in a closed state according to an embodiment. FIG. 2 is a drawing showing the opening of a fall prevention safety fence according to an embodiment from the front. FIG. 3 is a front view of a fall prevention safety fence in an open state according to an embodiment. FIG. 4 is an enlarged view of the first and second fixed supports of a fall prevention safety fence according to an embodiment. FIG. 5 is an enlarged view of the first and second moving supports of a fall prevention safety fence according to an embodiment. Figure 6 is a cross-sectional view taken along the line A-A' of Figure 4. Figure 7 is a cross-sectional view taken along the line B-B' of Figure 4.

The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to make the present disclosure complete and to fully inform those skilled in the art of the scope of the invention, and the present disclosure is defined only by the scope of the claims. Throughout the specification, like reference numerals refer to like components. Referring to FIG. 1, which is a front view of the open state of the fall prevention safety fence (10) [hereinafter referred to as 'fall prevention safety fence (10)'] according to the embodiment, the fall prevention safety fence (10) is installed at an entrance to enable the entrance to be opened and closed, and includes a first fixed support (100), a second fixed support (200), a first moving support (300), a second moving support (400), a first horizontal bar (500), a second horizontal bar (600), a third horizontal bar (700), and a fourth horizontal bar (800). Additionally, the fall prevention safety fence (10) has a second fixed support (200), a second moving support (400), a third horizontal bar (700), and a fourth horizontal bar (800) arranged symmetrically with respect to the first fixed support (100), the first moving support (300), the first horizontal bar (500), and the second horizontal bar (600). Referring to FIG. 4, which is an enlarged view of the first and second fixed supports (100, 200) of the fall prevention safety fence (10), the first fixed support (100) is installed vertically on one side of the entrance floor. The first fixed support (100) is fixed vertically to the floor and functions as a support when the fall prevention safety fence (10) is opened. As one example, the first fixed support (100) is formed in the shape of a vertically long column and includes a fixing plate (110) and a fixing pipe (120). The fixing plate (110) may be in the shape of a thin plate and is fixedly installed on one side of the entrance floor by an anchor to support the fixing pipe (120) so that it does not tip over. The fixed pipe (120) is made of metal and can be installed vertically in the center of the fixed plate (110). In addition, a cover (not shown in the drawing) made of synthetic resin material that surrounds the fixed pipe (120) may be provided. The first fixed support (100) has a first joint part (130) and a second joint part (140) formed therein. The first joint portion (130) is formed protruding from the side body side of the first fixed support (100). The second joint portion (140) is formed on the upper side of the first fixed support (100). The first joint portion (130) is formed to extend longer in the direction of the first moving support (300) than the second joint portion (140). Additionally, the second joint portion (140) may be formed to protrude in the directi
