[0011] However, the corner connection members of these existing cable ducts cause the following problems.

[0012] (1) Existing corner connecting members have a complex structure, which not only requires higher manufacturing costs but also reduces construction efficiency because it takes a long time to connect cable ducts.

[0013] (2) In particular, when installing cable ducts in large spaces such as large parking lots or industrial sites, many corner connecting members are used as the space increases. As the number of corner connecting members increases, the installation time of the cable duct also increases, and the efficiency of the installation decreases further.

[0014] (3) In addition, there is no major problem when the ceiling in the indoor space where the cable duct is installed is constructed in a flat shape, but when the ceiling is curved or sloped, such as under a step or stairs, it is difficult to connect the cable duct with existing corner connecting members.

[0015] The present invention takes these points into consideration and aims to provide a cable duct corner connecting member that can be assembled easily and conveniently by anyone and safely used by inserting the two sides of a cable duct with a width cross-section in the shape of an "H" so that they are in close contact, thereby forcibly fitting the opposing sides together for assembly, making the horizontal part of the cable duct become one plane with the flat part of the corner connecting member, and then fitting the connecting member so that it is in close contact with the horizontal part and the flat part, sliding the assembly, and fastening it with a screw.

[0028] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention in accordance with the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0029] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0030] [Configuration of Cable Duct Corner Connection Members]

[0031] The cable duct corner connecting member according to the present invention includes an elbow member (100) and a connecting member (200) so as to be able to connect two cable ducts (10) with a width cross-section in the shape of an "H" as shown in FIGS. 1 to 9.

[0032] In particular, the above elbow member (100) is assembled by fitting at least two cable ducts (10) so that each end part is forcibly fitted, and the connecting member (200) is fixed integrally by overlapping the flat part (110) of the above elbow member (100), which is formed into a single flat shape by contacting each other, and the base (12) surface of the above cable duct (10) with a screw, thereby making the structure simple and allowing for easy assembly and construction.

[0033] At this time, the elbow member (100) is configured so that 2 to 4 cable ducts (10) can be installed on a single virtual plane, or two cable ducts (10) are formed to have a predetermined obtuse angle, thereby allowing the corners to be connected in various forms when installing the cable ducts (10).

[0034] The following is a more detailed explanation of this configuration with reference to the attached drawings.

[0035] a. Cable duct

[0036] As shown in FIGS. 1 to 4, the cable duct (10) is formed such that two sides (11) are arranged facing each other and parallel, and a base (12) is formed to integrally connect these sides (11) in between, so that the overall width cross-section is made in the shape of an "H". In addition, a first guide (13) is formed on the sides (11) at a certain height interval from the edge where it meets the base (12), so that a connecting member (200), which will be described later, can slide and guide on the surface of the base (12). This cable duct (10) is configured so that a cable can be installed on the base (12) and a lighting facility can be installed below the base (12).

[0037] me. elbow absence

[0038] The elbow member (100) comprises, as shown in FIGS. 1 to 5, one planar portion (110) and at least two connecting portions (120) formed in pairs to be orthogonal to the planar portion (110). Here, for convenience of explanation, an example is given in which there are two connecting portions (120).

[0039] 1. Planar part

[0040] The flat portion (110) is configured such that the cable is draped over it as shown in FIGS. 2 to 5, and two connecting portions (120) to be described later can be assembled at right angles, thereby allowing two cable ducts (10) to be assembled at right angles. Accordingly, the flat portion (110) is formed in an "L" shape.

[0041] 2. Connecting part

[0042] As shown in FIGS. 2 to 5, the connecting portion (120) is formed on the aforementioned planar portion (110) and is in close contact with the outer surface of the side (11) so that two cable ducts (10) can be assembled orthogonally. Accordingly, the connecting portion (120) is formed in pairs to fix one cable duct (10), and two connecting portions (120) are configured so that two cable ducts (10) can be connected to one planar portion (110).

[0043] That is, in the above-described planar portion (110), as shown in FIGS. 2 to 5, two connecting portions (120) are formed, one on each side of the planar portion (110) which is shaped like an "L". At this time, each connecting portion (120) is integrally formed on both sides based on the planar portion (110), so that the planar portion (110) and each connecting portion (120) together form an "H" shape. Here, the size of the "H" shape is slightly larger than the size of the "H" shape of the cable duct (10) described above, so that when the cable duct (10) is inserted between the connecting portions (120), the side (11) of the cable duct (10) comes into close contact with the inner surface of the connecting portion (120), and the base (12) is formed to a size that can form a single plane with the above-described planar portion (110).

[0044] Meanwhile, in the above-mentioned connecting part (120), a jaw (121) and a second guide (122) are formed as shown in [Figs. 2] to [Figs. 5].

[0045] 1. Jaw

[0046] The jaw (121) is formed in a position where the thickness portion of the side (11) can be forcibly fitted and assembled when the base (12) comes into contact with the flat portion (110) as the side (11) of the cable duct (10) is assembled so that it is in close contact between the pair of connecting portions (120) described above, as shown in FIG. 3 to FIG. 5. At this time, two jaws (121) are integrally formed, one on each of the surfaces facing each other in the pair of connecting portions (120) that face each other.

[0047] 2. Second Guide

[0048] The second guide (122) is formed at a position extending from the first guide (13) described above when the cable duct (10) is assembled to the coupling part (120) as shown in FIGS. 2 to 5, so that the flat part (110) and the base (12) come into contact. At this time, two of the second guides (122) are also integrally formed, one on each side facing each other, in the coupling part (120) which is formed in pairs facing each other.

[0049] The second guide (122) formed in this way allows the planar portion (110) and the base (12) to be slidably connected by a connecting member (200) described later, as shown in FIG. 3 and FIG. 4, so that the planar portion (110) and the base (12) can be fastened and fixed to the connecting member (200) with a screw.

[0050] C. Connecting member

[0051] The connecting member (200) is a member that is fastened to the base (12) and the flat portion (110) with a screw by being in close contact with the flat portion (110) when the base (12) and the flat portion (110) described above form a single plane, as shown in FIGS. 1 to 4.

[0052] At this time, as shown in FIG. 2, the connecting member (200) is slidably coupled so that a part of it is placed over the surface of the base (12) and catches on the first guide (13), and the remaining part is slidably coupled so that it catches on the second guide (122) while placed over the flat portion (110), thereby forming an integral connection. The connecting member (200) is thus assembled integrally by being fastened with a screw while overlapping the base (12) and the flat portion (110).

[0053] The cable duct corner connecting member according to the present invention, constructed as described above, has a simple structure that allows it to be manufactured easily and inexpensively, and also enables quick and convenient installation by being easily assembled.

[0054] In addition, the present invention can be used with various modifications depending on the number and mounting direction of the cable ducts, as shown in FIGS. 6 to 9. That is, as shown in FIG. 6, an elbow member (100a) can be formed so that the angle formed by the two connecting parts in the above-described embodiment becomes an obtuse angle, allowing two cable ducts to be assembled at an obtuse angle on a single plane. Also, as shown in FIG. 7, an elbow member (100b) can be formed so that a part of the plane is bent to form an obtuse angle between the two connecting parts, and the cable duct mounted on the connecting part spans across two planes rather than a single plane. Furthermore, as shown in FIG. 8, an elbow member (100c) can be formed so that three cable ducts form a single plane, or as shown in FIG. 9, an elbow member (100d) can be formed so that four cable ducts can be installed on a single plane.
