Description

Safety fence assembly to prevent suicide by jumping

[0001] The present invention relates to a safety fence assembly for preventing suicide by jumping, and more particularly, to a safety fence assembly for preventing suicide by jumping, which automatically raises the upper part of the fence with just a one-touch operation of pressing the upper part of the fence, thereby blocking an attempted suicide by jumping in advance and preventing an accident.

[0002] Recently, the frequency of suicide incidents involving jumping from bridges or high-rise buildings has been increasing.

[0003] Facilities to prevent such suicides include fences installed at the edges of bridges and high-rise buildings.

[0004] However, fences installed for bridge railings on rivers or the sea must be installed at a relatively low height of 1.2 m to 1.5 m, taking into consideration wind loads applied to the bridge, harmony with the surrounding landscape, design, and visibility.

[0005] Therefore, these conventional fences had a limitation in that they were not effective in preventing a suicide attempter from climbing over the fence and intentionally jumping because of their low installation height.

[0006] Also, fences installed on the rooftops of large buildings should be installed at a height of about 2 to 3 m to prevent falls, but in most cases, they are installed at a relatively low height of about 1.2 to 1.5 m for reasons such as aesthetics and cost reduction as mentioned above.

[0007] That is, it is pointed out that the fences on the roofs of these large buildings, like those on bridges, are not effective in preventing intentional jumping.

[0008] Therefore, it is urgent to develop a device that actively prevents suicide attempts by jumping over fences or intentional attempts by drunk people in a state of mental confusion, and prevents accidents caused by such attempts in advance.

[0040]

[0041] As shown in FIGS. 1 and 2, the present invention may include a base (400) forming the edge of a bridge or a high-rise building, a fixed railing member (100) installed along the upper surface of the base (400), an access railing member (200) installed on the fixed railing member (100) and capable of being entered and exited, and a prevention means (300) installed on the upper portion of the access railing member (200) to protrude and rise the access railing member (200) from the fixed railing member (100) when a load is detected.

[0042] The present invention can be applied to embodiments of the above configuration, and of course, the following various embodiments can also be applied.

[0043]

[0044] First, the fixed railing member (100) is installed on a base (400) and may include a housing (110) having an operating space (101) inside and an open upper surface.

[0045] Here, it can be seen that the access railing member (200) described later is installed to enable entry and exit from the housing (110).

[0046] At this time, the fixed railing member (100) may further include a first catch rib (120) that is formed to protrude and face each other along the left and right edges of the open upper surface of the lower housing (110) to prevent the lower part of the entrance railing member (200) from being separated and detached from the lower housing (110).

[0047]

[0048] Meanwhile, the entrance railing member (200) may include an entrance frame (210) that is accommodated in an operating space (101) formed inside the fixed railing member (100) and is capable of being entered and exited from the fixed railing member (100).

[0049] In addition, the entrance railing member (200) has upper and lower ends that connect the lower end of the entrance frame (210) and the inner bottom surface of the fixed railing member (100) to each other, and may include a vertical spring (230) that generates elastic force in the direction of pushing up the entrance frame (210).

[0050] In addition, the access railing member (200) may further include a second catch rib (220) that is formed to protrude along both edges of the lower portion of the access frame (210) and that prevents the access frame (210) from being separated and detached from the open upper surface of the fixed railing member (100).

[0051] The second hooking rib (220) has an upper surface that is hooked and fixed to the lower surface of each of the first hooking ribs (120) that are formed to face each other and protrude from both edges of the open upper surface of the fixed railing member (100).

[0052]

[0053] Meanwhile, the prevention means (300) may include an upper horizontal member (310) that rotates with respect to the upper part of the access railing member (200) when the load and pressure caused by the suicide attempt of a person attempting suicide (hereinafter not shown) from a high-rise building are detected, and is normally perpendicular to the access railing member (200).

[0054] And, the prevention means (300) may include a cylindrical rotating body (320) that is rotatably mounted on one edge of the upper horizontal member (310) to prevent the person attempting to jump from being caught.

[0055] In addition, the prevention means (300) may include a safety catch (330) that extends from the other end edge of the upper horizontal member (310) and keeps the access railing member (200) in a state of being stored in the fixed railing member (100) in normal times, and keeps it in a state of being caught and fixed on the upper end of the fixed railing member (100).

[0056] Here, the safety catch (330) may include an extension rib (332) that is bent from the other end edge of the upper horizontal member (310) and extends toward the upper surface of the fixed railing member (100) to face one side of the upper portion of the entrance railing member (200) and, at the same time, faces one side of the upper portion of the fixed railing member (100) in normal times.

[0057] At this time, the safety catch (330) may include a fourth catch rib (334) that is bent from the lower edge of the extension rib (332) and is parallel to the upper horizontal member (310), and is normally caught and fixed by a third catch rib (130) that is formed by extending from one side of the upper end of the fixed railing member (100).

[0058] In addition, the present invention may further include a fifth hooking rib (250) that is formed by protruding from both sides of the upper portion of the access railing member (200) and is normally hooked and secured to both edges of the open upper surface of the fixed railing member (100).

[0059] In addition, the present invention may further include a horizontal spring (340) having both ends connected to the fifth hanging rib (250) and the extension rib (332), respectively, and allowing elastic deformation.

[0060] Here, it goes without saying that the prevention means (300) may further include an upper pin member (350) installed on the upper surface of the entrance railing member (200) to support the inclined rotation of the upper horizontal member (310).

[0061] At this time, the upper pin member (350) further includes a rib bracket (352) that is formed to protrude from the upper surface of the entrance frame (210) of the entrance railing member (200), and the upper pin member (350) is formed at the upper end of the rib bracket (352) to support the inclined rotation of the upper horizontal member (310).

[0062]

[0063] Meanwhile, an installation panel (140) having an upper surface facing the lower surface of the fixed railing member (100) and detachably coupled to the upper surface of the base (400) may be further provided.

[0064] The installation panel (140) is provided to provide convenience in terms of maintenance, such as inspection and replacement, of the assembly according to the present invention, including the fixed railing member (100), the entry railing member (200), and the prevention means (300).

[0065] That is, since the fixed railing member (100) can be easily separated from the base (400) by simply removing the installation panel (140), convenience in various tasks such as internal inspection or repair can be ensured.

[0066]

[0067] Meanwhile, the fixed railing member (100), the entrance railing member (200), and the prevention means (300) are provided in the form of unit units divided into a certain length along the edge of the bridge or high-rise building, and the unit units can be arranged in a row in multiple numbers along the formation direction of the bridge or high-rise building on the upper surface of the base (400).

[0068] Therefore, if a jumping attempt occurs among multiple units or a damaged part is damaged due to wind load or other external impacts, the unit can be reused by replacing only the unit in question.

[0069]

[0070] Meanwhile, the prevention means (300) may be arranged throughout the entire access railing member (200) along with the concept of the aforementioned unit, and may further include an alarm device (not shown) that transmits an alarm sound or warning broadcast as the access frame (210) of the access railing member (200) rises from the housing (110) in order to rescue a person attempting to jump from the scene in a short period of time.

[0071] In addition, the prevention means (300) may further include a wired or wireless communication device (not shown) on one side of the access railing member (200) or fixed railing member (100) that automatically makes an emergency report to a related agency such as 112 or 119.

[0072] In addition, although the prevention means (300) is not specifically illustrated, it is possible to design applications and modifications that make it very difficult for a person attempting to jump over the fence to do so by providing an auxiliary means, such as a rotating device such as a roller or wheel, parallel to the rotating body (320) across the entire upper horizontal member (310) in addition to the aforementioned cylindrical rotating body (320).

[0073]

[0074] Hereinafter, the operation process of the safety fence assembly for preventing suicide by jumping according to various embodiments of the present invention will be briefly examined with reference to FIG. 1 and FIG. 2.

[0075]

[0076] First, when a person attempting to jump approaches the fixed railing member (100) where the access railing member (200) is stored and performs an action such as grabbing the upper horizontal member (310) of the prevention means (300) and climbing up, load and pressure are applied in the direction of the transparent arrow as shown in ①, and the upper horizontal member (310) rotates and tilts based on the upper pin member (350) as shown in ②.

[0077] Accordingly, the fourth hook rib (334) is released from its hooked state with the fifth hook rib (250), and the vertical spring (230), which was pressed and compressed by the lower part of the access frame (210), generates elastic force in the direction of pushing up the access frame (210) as indicated by the transparent arrow in ③, and when the access frame (210) is raised, the access frame (210) is raised to a height at which jumping itself is impossible, as shown in FIG. 1.

[0078]

[0079] Hereinafter, the operation and effect of a safety fence assembly for preventing suicide by jumping according to a preferred embodiment of the present invention will be examined as follows.

[0080]

[0081] First, the present invention is characterized by including a base (400) forming the edge of a bridge or a high-rise building; a fixed railing member (100) installed along the upper surface of the base (400); an access railing member (200) installed on the fixed railing member (100) and capable of being entered and exited; and a prevention means (300) installed on the upper end of the access railing member (200) to protrude and rise the access railing member (200) from the fixed railing member (100) when a load is detected, so that when a person attempting to jump presses the upper end of the fence to go over the fence, that is, the height of the fence automatically rises in a one-touch manner, thereby not only discouraging the person attempting to commit suicide, but also because the fence itself functions as an active jumping prevention means, it is possible to achieve the effect of fundamentally blocking jumping attempts.

[0082] In addition, the fixed railing member (100) according to the present invention is installed on a base (400) and includes a housing (110) having an operating space (101) inside and an open upper surface, and the entrance railing member (200) is installed so as to be able to enter and exit from the housing (110), so that in normal times, an appropriate height is maintained considering the wind load applied to a bridge or a high-rise building, harmony with the surrounding landscape, design, visibility, etc., and in an emergency such as a suicide attempt, the member can be raised with a one-touch operation to prevent accidents, so that both appearance and safety can be sought.

[0083] In addition, the fixed railing member (100) according to the present invention further includes a first catch rib (120) that is formed to face each other along the left and right edges of the open upper surface of the lower housing (110) and protrudes to prevent the lower part of the entrance railing member (200) from being separated and detached from the lower housing (110), thereby achieving a psychological calming effect that can discourage the suicide intention of a person attempting suicide who witnesses the entrance railing member (200) being raised.

[0084] In addition, the access railing member (200) according to the present invention has an access frame (210) that is accommodated in an operating space (101) formed inside a fixed railing member (100) and is capable of being entered and exited from the fixed railing member (100), and has upper and lower ends that connect the lower end of the access frame (210) and the inner bottom surface of the fixed railing member (100), and includes a vertical spring (230) that generates elastic force in a direction that pushes up the access frame (210), thereby having a special advantage in that the access railing member (200) can be re-stored in the fixed railing member (100) after the attempt of a person attempting to jump is prevented by using the elastic force of the vertical spring (230), and can be reused.

[0085] In addition, the entrance railing member (200) according to the present invention further includes a second catch rib (220) having an upper surface that is caught and fixed on the lower surface of each of the first catch ribs (120) that are formed to protrude along both edges of the lower portion of the entrance frame (210) and face each other from both edges of the open upper surface of the fixed railing member (100) to prevent the entrance frame (210) from being separated and detached from the open upper surface of the fixed railing member (100), thereby achieving a psychological calming effect that can discourage the suicide intention of a person who has attempted suicide by witnessing the state in which the entrance frame (210) is raised.

[0086] And, the prevention means (300) according to the present invention, when the load and pressure due to the high-rise building of a suicide attempter (hereinafter not shown) are detected, rotates with respect to the upper part of the entrance railing member (200), and includes an upper horizontal member (310) that is normally perpendicular to the entrance railing member (200), a cylindrical rotating body (320) that is rotatably mounted with respect to one end edge of the upper horizontal member (310) to prevent the suicide attempter from grabbing, and a safety catch (330) that extends from the other end edge of the upper horizontal member (310) and maintains a state of being caught and fixed with respect to the upper end of the fixed railing member (100) so that the entrance railing member (200) is normally kept in a state of being received in the fixed railing member (100), thereby making it possible to secure a structure in which it is absolutely impossible for a suicide attempter to step on the railing and jump or to maintain balance so as to cause a riot for the purpose of attempting suicide. It works.

[0087] In addition, the prevention means (300) according to the present invention further includes a horizontal spring (340) that allows elastic deformation by having both ends fixed to one side of the upper end of the safety catch (330) and the entrance / exit railing member (200), thereby having the special advantage of being able to be reused by re-housing the entrance / exit railing member (200) in the fixed railing member (100) after preventing a person attempting to jump by using the elastic force of the horizontal spring (340).

[0088] In addition, the safety catch (330) according to the present invention includes an extension rib (332) that is bent from the other end edge of the upper horizontal member (310) and extends toward the upper surface of the fixed railing member (100) to face one side of the upper end of the entrance railing member (200) and, at the same time, faces one side of the upper end of the fixed railing member (100) in normal times, and a fourth catch rib (334) that is bent from the lower edge of the extension rib (332) and is parallel to the upper horizontal member (310) and is fixed by catch to the third catch rib (130) that is extended from one side of the upper end of the fixed railing member (100) in normal times, thereby enabling the fence to perform its normal function of maintaining an appropriate height in consideration of wind loads applied to bridges or high-rise buildings, harmony with the surrounding landscape, design, visibility, etc.

[0089] In addition, according to the present invention, the fifth catch rib (250) is formed by protruding from both sides of the upper portion of the entrance railing member (200) and is normally caught and rested on both edges of the open upper surface of the fixed railing member (100), and a horizontal spring (340) having both ends respectively connected to the fifth catch rib (250) and the extension rib (332) and allowing elastic deformation is further included, thereby having the special advantage of being able to reuse the entrance railing member (200) by re-accommodating it in the fixed railing member (100) after preventing a person attempting to jump by utilizing the elastic force of the horizontal spring (340).

[0090] In addition, the prevention means (300) further includes an upper pin member (350) installed on the upper surface of the entrance railing member (200) to support the inclined rotation of the upper horizontal member (310), thereby making it possible to secure a structure in which it is absolutely impossible for a person attempting to jump to step on the railing and maintain balance to jump or to cause a disturbance for the purpose of attempting to jump.

[0091]

[0092] As described above, it can be seen that the present invention has as its basic technical idea a safety fence assembly for preventing suicide by jumping, which automatically raises the upper part of the fence with just a one-touch operation of pressing the upper part of the fence, thereby blocking suicide attempts in advance and preventing accidents.

[0093] And, of course, many other modifications and applications are also possible for those with common knowledge in the industry within the scope of the basic technical idea of ​​the present invention.
