Description

Technology Field

[0001] The present invention relates to a safety fence that can be installed on a ramp, and more specifically, to a safety fence that can be installed on a ramp by adjusting the angle through rotation and can be reused after separation because it is not welded. Background Technology

[0002] Safety fences, also known as guard rails, are generally installed along roadsides and serve to clearly define the boundaries of the roadway, prevent vehicles from rushing onto the sidewalk, and keep pedestrians or pets from entering the road. In other words, they are safety devices that not only reduce potential accidents between parties but also prevent vehicles from veering off and falling, especially when installed on elevated roads or port roads.

[0003] Furthermore, safety fences can be installed to prevent jaywalking, protect children, and on bridge railings, sidewalk railings, and fences to mitigate accident risks. In particular, they are installed to prevent accidents caused by vehicles encroaching on sidewalks on both sides of the road due to unforeseen accidents or driver inexperience, or by jaywalking. In addition, safety fences can be installed to protect pedestrians in locations where accidents frequently occur, such as road boundaries, high retaining walls, bridges, sidewalks, and roads without sidewalks. Moreover, safety fences are installed in various ways depending on the purpose or location, including as boundaries for houses and buildings, along sidewalk facilities, and on apartment balcony railings and stair railings.

[0004] However, conventional safety fences are designed to be installed primarily on flat ground, making angle adjustment impossible; consequently, there is a problem with poor on-site applicability to changes in terrain, such as slopes and curved roads. Prior art literature

Specific details for implementing the invention

[0013] Hereinafter, the technical concept of the present invention will be explained in more detail using the attached drawings. The attached drawings are merely examples illustrated to explain the technical concept of the present invention in more detail, and therefore the technical concept of the present invention is not limited to the form of the attached drawings.

[0014] FIGS. 1 and 2 are front views of a safety fence according to an embodiment of the present invention, FIG. 3 is a detailed front view of the safety fence, FIG. 4 is a detailed perspective view of the safety fence, and FIG. 5 is a detailed side view of the safety fence.

[0016] A safety fence (10) that can be installed on a ramp according to an embodiment of the present invention can be installed on a ramp as well as on a flat surface by adjusting the angle through rotation, and includes a frame unit (100), a pipe unit (200), a rotation unit (300), and a fastening unit (400) as shown in FIGS. 1 and 2.

[0017] First, the frame unit (100) is configured such that a number of them are installed at regular intervals along the longitudinal direction of the ground, which is composed of flat ground or a slope, and is installed to have a predetermined height from the ground to serve to separate the roadway and the sidewalk. This frame unit (100) includes a vertical frame (110) and a horizontal frame (120).

[0018] A vertical frame (110) is configured such that one end is installed on the ground and the other end extends vertically from the ground, and a pair of vertical frames (110) are installed on the ground at a constant distance from each other. It is preferable that such a vertical frame (110) be made of a rigid metal material having a larger diameter than the vertical pipe (210) described later so that the safety fence (10) can be stably installed on the ground.

[0019] A horizontal frame (120) is configured as a pair installed horizontally between a pair of vertical frames (110), with one horizontal frame (120) installed at one end of a vertical frame (110) close to the ground and the other horizontal frame (120) installed at the other end of a vertical frame (110) extending from the ground. By this structure, the vertical frame (110) and the horizontal frame (120) form a frame unit (100) having a rectangular shape. Here, it is preferable that the horizontal frame (120) be made of a rigid metal material having a larger diameter than the vertical pipe (210) so that the safety fence (10) can be installed stably, just like the vertical frame (110).

[0020] In some cases, as shown in FIG. 3, a plurality of through holes (121) may be formed on the surface facing the vertical pipe (210) to be described later, and one vertical pipe (210) may be inserted into one through hole (121). When the vertical pipe (210) is inserted through the through hole (121) of the horizontal frame (120) in this way, the vertical pipe (210) can be stably supported without being detached from the horizontal frame (120) due to external impact.

[0021] These through holes (121) have a diameter of 2 to 3 times the diameter of the vertical pipe (210) along the longitudinal direction of the horizontal frame (120) to allow rotation of the vertical pipe (210), and are preferably formed with a diameter of 1.1 to 1.3 times the diameter of the vertical pipe (210) in a direction perpendicular to the longitudinal direction of the horizontal frame (120) so that the vertical pipe (210) does not deviate and friction does not occur when the vertical pipe (210) rotates. That is, it is preferable that the through holes (121) be formed in an elliptical shape along the longitudinal direction of the horizontal frame (120).

[0022] The vertical frame (110) and horizontal frame (120) can be fixed after being rotated to allow for angle adjustment, but if necessary, the vertical frame (110) and horizontal frame (120) may also be installed so as to be fixed to each other by welding after the angle of the pipe unit (200) described later is adjusted.

[0023] The pipe unit (200) is configured to include a plurality of vertical pipes (210) installed vertically within the frame unit (100), and a plurality of pipes are installed at regular intervals within the frame unit (100) to serve to partition spaces such as roadways and sidewalks. It is preferable that these plurality of vertical pipes (210) be made of a rigid metal material so that their shape is not deformed from external impact, but they may also be made of an elastic material that can mitigate impact if necessary.

[0024] The rotation unit (300) is installed at each end of the vertical pipe (210) and is configured to connect the horizontal frame (120) and the vertical pipe (210) so that the vertical pipe (210) can rotate from the horizontal frame (120), and includes a pipe cover (310), a frame cover (320), and a rotation member (330) as shown in FIGS. 3 and 4.

[0025] The pipe cover (310) is a pair of components installed to wrap around one end or the other end of the vertical pipe (210), and is installed at each end of the vertical pipe (210) to connect the vertical pipe (210) to the horizontal frame (120). That is, the pipe cover (310) allows the vertical pipe (210) to rotate from the horizontal frame (120) and at the same time protects both ends of the vertical pipe (210).

[0026] The pipe cover (310) includes a pair of semicircular pipe cover bodies (311) that surround the vertical pipe (210) along the outer surface of the vertical pipe (210), and a plate-shaped pipe cover wing portion (312) that extends outwardly from the pipe cover bodies (311). That is, the pipe cover (310) includes a pair of pipe cover bodies (311) and a pipe cover wing portion (312) to facilitate installation on the vertical pipe (210). When the pair of semicircular pipe cover bodies (311) are arranged to surround the vertical pipe (210), and the fastening unit (400) described later is fastened by penetrating the pipe cover wing portion (312), the pipe cover (310) can be elastically installed while pressing against the vertical pipe (210).

[0027] The frame cover (320) is installed to surround the horizontal frame (120) and is configured as a pair of pipe covers (310) that can each be inserted, comprising a frame cover body (321), a frame cover wing portion (322), and an insertion portion (323).

[0028] The frame cover body (321) is configured in a semicircular shape that wraps around the horizontal frame (120) along the outer surface of the horizontal frame (120), and by being formed as a pair of semicircular shapes, it is possible to wrap around the horizontal frame (120) having a circular cross-section. This is so that the frame cover body (321) is formed as a pair to facilitate installation on the horizontal frame (120), and the pair of frame cover bodies (321) can be installed on the horizontal frame (120) so that they face each other.

[0029] The frame cover wing portion (322) is configured as a plate shape extending outward from the frame cover body (321) and serves to provide a space for the fastening unit (400), which will be described later, to be fastened so that the frame cover (320) can be installed on the horizontal frame (120). It is preferable that such frame cover wing portions (322) be formed as a pair, each oriented upward and downward from the direction in which the frame cover (320) is installed on the horizontal frame (120).

[0030] The insertion part (323) is configured to be formed on the frame cover wing part (322) facing the pipe cover (310) so that the pipe cover (310) can be inserted, and is formed on the frame cover wing part (322) facing the pipe cover (310) among a pair of frame cover wing parts (322).

[0031] In detail, the insertion part (323) installed on the horizontal frame (120) close to the ground, into which one end of the vertical pipe (210) is inserted, is formed on the frame cover wing part (322) formed to face upward among a pair of frame cover wing parts (322), into which one end of the vertical pipe (210) and the pipe cover (320) are inserted, and the frame cover (320) installed on the horizontal frame (120) spaced apart from the ground has the insertion part (323) formed on the frame cover wing part (322) formed to face downward among a pair of frame cover wing parts (322), into which the other end of the vertical pipe (210) and the pipe cover (310) are inserted.

[0032] At this time, the insertion part (323) is preferably formed radially such that the inner diameter gradually increases from the inner side to the outer side of the frame cover wing part (322) connected to the frame cover body (321), and such a shape serves to provide space for the vertical pipe (210) and pipe cover (310) inserted into the insertion part (323) to rotate. It is preferable that the insertion part (323) be formed at an angle of 15 to 30° with respect to the vertical direction so that the vertical pipe (210) can rotate at 15 to 30°, but if the insertion part (323) is formed at an angle of less than 15°, there is insufficient space for the vertical pipe (210) to rotate, and if it exceeds 30°, it fails to sufficiently form a space for the connection between the frame cover wing part (322) and the fastening unit (400).

[0033] The pivot member (330) is configured to be installed by penetrating the pipe cover (310) and the frame cover (320) so that the pipe cover (310) can rotate, and serves to connect the pipe cover (310) and the frame cover (320) so that the vertical pipe (210) and the pipe cover (310) can be installed on the frame cover (320) and rotate. It is preferable that such a pivot member (330) be formed in a bolt-nut shape to facilitate connection, but it is not limited thereto.

[0034] The fastening unit (400) is configured to fasten the rotating unit (300) to the vertical pipe (210) and the horizontal frame (120), and includes a pipe fastening member (410) and a frame fastening member (420).

[0035] The pipe fastening member (410) is configured to fasten the pipe cover (310) to the vertical pipe (210) and is installed on each side of the pipe cover wing portion (322) of the pipe cover (310) to fasten the pipe cover (310) and the vertical pipe (210). At this time, the pipe fastening member (410) serves to elastically press the pipe cover (310) so that the pipe cover (310) and the vertical pipe (210) can be in close contact. It is preferable that such a pipe fastening member (410) be formed in the shape of a bolt and nut, but it is not limited thereto.

[0036] The frame fastening member (420) is configured to fasten the frame cover (320) to the horizontal frame (120) and is installed on each side of the frame cover wing portion (322) of the frame cover (320) to fasten the frame cover (320) to the horizontal frame (120). At this time, the frame fastening member (420) functions to elastically press the frame cover (320) so that the frame cover (320) and the horizontal frame (120) can be in close contact, as shown in FIG. 5.

[0037] In detail, to ensure superior durability compared to when the frame cover (320) is welded to the horizontal frame (120), the upper and lower sides of the frame cover (320) are made to come into contact with the horizontal frame (120) as shown in FIG. 5(a). When the frame cover body (321), which is made of a semicircular shape, forms a fine space with the horizontal frame (120) and the frame fastening member (420) is fastened, the frame cover (320) can be installed so as to elastically come into contact with all outer surfaces of the horizontal frame (120) as shown in FIG. 5(b).

[0039] Conventional safety fences have relied on welding for every connection point between the horizontal frame and the vertical pipe; consequently, this necessitated the cumbersome process of pre-fabricating the fence to match the slope angle before installation on ramps. Such conventional safety fences had the disadvantage of increasing labor costs and making it difficult to cope with on-site variables, such as rain or vehicle traffic, due to the additional welding required during construction.

[0040] Accordingly, the safety fence (10) of the present invention can rotate the vertical pipe (210) using a rotating unit (300) and a fastening unit (400) instead of welding between the horizontal frame (120) and the vertical pipe (210), so that the angle of the vertical pipe (210) can be adjusted according to the angle of the ramp as shown in FIG. 2, thereby enabling customized construction at the site.

[0041] In addition, conventional safety fences cannot be reused due to the welding process, but the safety fence (10) of the present invention has the advantage of being reusable by changing the angle according to the terrain because it is assembled.

[0042] The present invention is not limited to the embodiments described above, and its scope of application is diverse. Furthermore, it is understood that various modifications are possible without departing from the essence of the invention as claimed in the claims. Explanation of the symbols
