Description

Technology Field

[0001] The present invention relates to a smart safety fence, and more specifically, to a smart safety fence developed to prevent the extent of damage caused by broken pieces of the guardrail resulting from a collision with a vehicle, and to enable the driver of a vehicle to easily recognize changes in signals according to the situation of a pedestrian walking on the sidewalk. Background Technology

[0003] Generally, fences, or railings, are installed at the boundaries of areas to prevent intrusion into the area or for the purpose of ensuring safety within the area, and are installed for various purposes.

[0004] For purposes targeting people, fences are installed in various locations, ranging from fences formed around buildings to fences installed at the boundary between roadways and sidewalks. In the past, the main purpose of fences installed between roadways and sidewalks was to prevent people from entering the roadway, and for the purpose of protecting the sidewalk, most fences were formed by creating a curb so that the sidewalk was higher than the roadway on the curb stones.

[0005] These road curbs are not effective in preventing high-speed vehicles from encroaching on sidewalks, so school zones are mainly formed near schools to limit traffic speeds to 30 km / h or less.

[0006] However, even a speed of 30 km / h cannot serve as an absolute standard to prevent vehicles on the roadway from encroaching on the sidewalk, and especially in school zones, when speeding at a higher speed, even if safety fences are installed, they are easily damaged and encroach on the sidewalk.

[0007] At this time, there is a concern that the damage could spread if the collision energy from the vehicle causes the multiple frames constituting the fence to separate and fly in all directions, and above all, accidents caused by a vehicle encroaching on the sidewalk are a cause of significant casualties.

[0008] Therefore, it can be said that research is needed on a method to prevent vehicles from encroaching on the sidewalk while preventing the frame constituting the fence from separating even if a vehicle collides with the safety fence, and a method to enable drivers to easily identify the situation of pedestrians beyond the safety fence and drive more cautiously in advance.

[0016] In addition, one or more of the two wire fixing parts are characterized by having a winding roll in which a wire rope is wound, a ratchet gear composed of a ratchet wheel and a stopper that rotates only in the direction in which the wire rope is wound, and a torsion spring that provides an elastic restoring force to the rotation in the direction in which the wire rope is unwound.

[0017] In addition, the invention is characterized by further comprising a guide post that is vertically installed between the vertical post and the wire fixing part, with a plurality of horizontally penetrating holes in the middle each having a direction changing roller mounted thereon, so that a wire rope extending upward from the wire fixing part passes through the direction changing roller and extends horizontally.

[0018] In addition, the interior of the vertical post is further characterized by having a guide roller that supports the lower part of a horizontally penetrating wire rope.

[0019] In addition, the vertical frame is characterized by additionally providing an auxiliary wire rope that penetrates the internal hollow and is fixed at the top and bottom ends to a wire rope that penetrates the hollow of the horizontal frame, respectively.

[0020] In addition, the two ends of the auxiliary wire rope are configured to be fixed to the wire ropes located at the top and bottom, respectively.

[0027] In addition, the detection sensor formed at the top of the vertical post detects the presence of pedestrians and sends a light signal toward the roadway, allowing drivers to easily identify pedestrians on the sidewalk and exercise greater caution, thereby effectively preventing accidents. Brief explanation of the drawing

[0029] FIG. 1 is a perspective view according to an embodiment of the present invention. FIG. 2 is a partial perspective view according to an embodiment of the present invention. FIG. 3 is a conceptual diagram according to an embodiment of the present invention. FIG. 4 is a conceptual diagram according to another embodiment of the present invention. Specific details for implementing the invention

[0030] Accordingly, the configuration of the present invention is described in detail below with reference to the attached drawings so that those skilled in the art can easily understand and reproduce it.

[0031] FIG. 1 is a perspective view according to an embodiment of the present invention, FIG. 2 is a partial perspective view according to an embodiment of the present invention, and FIG. 3 is a conceptual diagram according to an embodiment of the present invention. A safety fence (1) comprises a plurality of vertical posts (11) that are vertically erected and fixed at a certain interval at the boundary between a roadway and a sidewalk, and a plurality of horizontal frames (12) that are spaced apart vertically and parallelly to connect the adjacent vertical posts (11); a wire fixing part (14) fixed to the upper surface of a foundation stone (141) that is embedded in the ground spaced apart from both ends of the safety fence (1); One side shows a smart safety fence (1) characterized by having a plurality of wire ropes (15) that pass through the hollows of a plurality of vertical posts (11) and a horizontal frame (12) at the wire fixing part (14) and are connected to a wire fixing part (14) formed on the other side.

[0032] The present invention is intended to solve the problem that, although most safety fences (1) are composed of vertical posts (11) and horizontal frames (12) in the present invention or additionally include a plurality of vertical frames (13) that vertically connect adjacent upper and lower horizontal frames (12), when a vehicle collides, the frames are often separated by the collision and fly in all directions, thereby spreading the damage range.

[0033] On the other hand, wire fences with horizontally connected wires are installed in places other than where a vehicle collides and are often intended for people or animals. The present invention is configured to prevent the wire rope (15) from being blown away by the wire rope (15) penetrating the interior even if each frame is separated by connecting a more robust rope-shaped wire rope (15).

[0034] At this time, in a conventional wire fence, the end of the wire is fixed to the part corresponding to the vertical post (11) of the present invention, but the present invention is designed to have wire fixing parts (14) fixed to the upper surface of the embedded foundation stone (141) at both ends so that the wire rope (15) is not pushed toward the sidewalk even in the event of a collision with a vehicle, thereby reducing the risk of the vehicle encroaching on the sidewalk.

[0035] Additionally, an embodiment is further presented in which at least one of the two wire fixing parts (14) is equipped with a winding roll (142) in which a wire rope (15) is wound, a ratchet gear (143) composed of a ratchet wheel and a stopper that causes the wire rope (15) to rotate only in the winding direction, and a torsion spring (144) that causes an elastic restoring force to act on the rotation in the unwinding direction of the wire rope (15).

[0036] In this embodiment, when the tension of the wire rope (15) is loose, the stopper of the ratchet gear (143) prevents reverse rotation so that the tension of the winding roll is prevented from weakening as the winding roll rotates.

[0037] With this configuration, when a vehicle collides, the winding roll rotates in reverse to prevent the wire rope (15) from being pushed toward the sidewalk. Furthermore, rather than being fixed too tightly, a torsion spring (144) is provided inside so that the winding roll (142) unwinds in the reverse direction upon collision and then returns to its original position by the torsion spring (144), which can be said to be a method to more effectively protect pedestrians against collisions.

[0038] At this time, the ratchet gear (142) and torsion spring (144) illustrated in the present invention are shown only as examples of shapes, and their size, position, and connection relationship may change.

[0040] In addition, the existing vertical post (11) has a hollow structure formed inside, and the path of the wire rope (15) extends obliquely from the wire fixing part (14) and is connected horizontally, so in the event of a strong collision, the vertical post (11) usually falls toward the sidewalk.

[0041] Accordingly, the present invention provides an embodiment characterized by additionally providing a guide post (16) which is vertically installed between the vertical post (11) and the wire fixing part (14), and has a plurality of horizontally penetrating holes in the middle each fitted with a direction changing roller (161), so that the wire rope (15) extending upward from the wire fixing part (14) passes through the direction changing roller (161) and extends horizontally.

[0042] That is, by providing guide posts (16) equipped with direction change rollers (161) at both ends to be more robust and prevent falling, and to allow the wire rope (15) to have a more natural bending path, and by ensuring that the lower end is firmly fixed to the foundation stone (141) as illustrated, falling due to collision can be effectively prevented.

[0043] At this time, it is shown that a guide roller (113) is additionally provided inside the vertical post (11) to support the lower part of the wire rope (15) that passes horizontally, thereby preventing the wire rope (15) from sagging. Although there is no need for a guide roller (113) in the vertical post (11) adjacent to the guide post (16), a guide roller (113) is shown for convenience.

[0045] In addition, the present invention provides an embodiment characterized by additionally providing an auxiliary wire rope (151) that penetrates the internal hollow of the vertical frame (13) and is fixed to a wire rope (15) at the top and bottom ends, respectively, penetrating the hollow of the horizontal frame (12); furthermore, an embodiment is presented characterized by the two ends of the auxiliary wire rope (151) being configured to be fixed to a wire rope (15) located at the top and bottom ends, respectively.

[0046] The above embodiment is designed to prevent damage that may occur when the vertically spaced wire ropes (15) are separated vertically during a collision of a vehicle. The auxiliary wire rope (151) maintains the vertical spacing of the wire ropes (15) to form a structure similar to a net, thereby allowing it to surround and cushion the vehicle during a collision.

[0048] In addition, the present invention provides an embodiment characterized by having a sensing sensor (111) that detects movement in the direction of the sidewalk at the upper part of the vertical post (11), and a plurality of first light-emitting parts (112) mounted in the direction of the roadway that emit a signal differentiated according to the sensing sensor (111).

[0049] Usually, safety fences (1) in school zones are mostly designed to allow vehicles to recognize that they are in a school zone through general markings or warning messages, and in the case of nighttime, they may have a function of emitting light or reflecting light, but if they are designed to have a function of informing the situation of pedestrians on the sidewalk, vehicles can drive with greater caution.

[0050] For example, when there are many pedestrians, the likelihood of a child suddenly running into the roadway while crossing the safety fence (1) or passing through it increases, and in such situations, a differential signal is sent to the driver to reduce speed or pay attention to the condition of the sidewalk, thereby reducing the risk of accidents.

[0052] FIG. 4 is a conceptual diagram according to another embodiment of the present invention, wherein the horizontal frame (12) is extended in the longitudinal direction by a combination of a part made of metal and a transparent part that allows internal light to be emitted externally in the direction of the roadway, a second light-emitting part (121) is mounted inside, and an extension frame (122) is inserted and fixed into the hollow of the part made of metal, with the outer edges of both ends reduced to a stepped shape; and the second light-emitting part (121) is configured to emit a signal differentiated according to a detection sensor (111).

[0053] Additionally, an embodiment is shown in which at least one of the plurality of vertical frames (13) is formed into a second extension frame (132) in which a third light-emitting part (131) is mounted inside, and the third light-emitting part (132) is configured to emit a signal differentiated according to the detection sensor (111).

[0054] The above embodiment allows for means to emit light not only on the first light-emitting part (112) of the vertical post (11) but also on the horizontal and vertical frames (12, 13), thereby making it easier for the driver to identify, and especially at night, the safety fence (11) can be identified quickly from a greater distance.

[0055] With this configuration, the need for the horizontal and vertical frames (12, 13) to have strong durability is reduced by the internal wire rope (15), and by using the wire rope (15) directly or wiring through a path to pass through the wire rope (15), it is easy to transmit power and signals to each light-emitting part, thereby enabling the formation of more complex light-emitting parts.
