Description

[Technical Field]

[0001] The present invention relates to an attachment for a cable trough and to a cable trough having an attachment mounted thereon. [Background technology]

[0002] Patent Document 1 describes a conventional cable trough. The wiring trough described in Patent Document 1 has connection adapters made of H-shaped steel attached to the upper ends of both side walls. The connection adapters have a lower fitting portion that is inverted concave on the lower side and an upper fitting portion that is concave on the upper side. The connection adapters are attached to the wiring trough by fitting both side walls of the wiring trough into the lower fitting portions. Side wall members are fitted into the upper fitting portions, and the side wall members are integrated with the side walls of the existing wiring trough so that they are flush with each other. This allows the wiring trough described in Patent Document 1 to have both side walls extended upward, increasing capacity. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-8405 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the side wall members are attached to the wiring trough simply by fitting both side walls of the wiring trough into the lower fitting portion of the connecting adapter, if force is applied to the side wall members from the wiring contained in the wiring trough, for example, the distance between the upper ends of the side wall members may widen, causing the lid to fall off.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a cable trough attachment and a cable trough to which the attachment is attached, the lid of which is less likely to fall off even if force is applied to the inner surface of the cable trough attachment. [Means for solving the problem]

[0006] One embodiment of the cable trough attachment of the present invention is an attachment for attaching to a cable trough having a trough body with a bottom wall and multiple side walls, and a lid that closes the upper opening surface of the trough body, to increase the volume of the cable trough, and comprises a plurality of side wall plates attached to the multiple side walls of the trough body and extending in the height direction of the trough body, and a top plate that connects the multiple side wall plates and faces the underside of the lid.

[0007] A cable trough with an attachment according to one aspect of the present invention includes a trough body having a bottom wall and a plurality of side walls, a lid that closes the upper opening of the trough body, and an attachment attached between the trough body and the lid to increase the volume of the cable trough. The attachment includes a plurality of side wall plates attached to the side walls of the trough body and extending in the height direction of the trough body, and a top plate that connects the side wall plates and faces the underside of the lid. [Effects of the Invention]

[0008] The cable trough attachment of the above aspect according to the present invention and the cable trough to which the attachment is attached have the advantage that the lid is unlikely to fall off even when force is applied from the stored items. [Brief explanation of the drawings]

[Figure 2]FIG. 2 is an exploded perspective view of a cable trough to which an attachment according to an embodiment is attached. [Figure 3] FIG. 3 is a cross-sectional view of a cable trough to which an attachment according to an embodiment is attached. [Figure 4] FIG. 4 is a perspective view of a top plate of the attachment according to the embodiment. [Figure 5] FIG. 5 is a perspective view of a top plate according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0010] <Embodiment> The attachment 4 of the cable trough 1 according to this embodiment and the cable trough 1 to which the attachment 4 is attached will be described in detail below with reference to the accompanying drawings. For ease of explanation, as shown in FIG. 1, the longitudinal direction of the cable trough 1 will be defined as the "lengthwise direction," the direction perpendicular to the lengthwise direction and along the horizontal plane as the "widthwise direction," and the direction perpendicular to the lengthwise direction and the widthwise direction as the "vertical direction." The lengthwise direction of the cable trough 1 will be described as being along the horizontal plane, but it may be inclined relative to the horizontal plane. However, the definitions of these directions do not specify the manner in which the cable trough 1 is used.

[0011] Furthermore, in this specification, "parallel" does not only mean that two straight lines, faces, sides, etc. (hereinafter referred to as "straight lines, etc.") do not intersect even when extended, but also includes cases where the straight lines, etc. intersect within 10° when extended. "Perpendicular" includes cases where two straight lines, etc. intersect within a range of 90°±10°, and also includes cases where two straight lines, etc. are actually separated but intersect when extended.

[0012] (Cable Trough 1) The cable trough 1 protects the cables by storing them inside. As shown in FIG. 2, the cable trough 1 includes a trough body 2 and a lid 3. There are no particular limitations on the material of the cable trough 1, and examples thereof include precast reinforced concrete, porcelain, ceramic, FRP, and synthetic resin. The items stored in the cable trough 1 may be cables only, or may include items other than cables. There are no particular limitations on the cables, and examples thereof include cables used for communication, power transmission, and the like.

[0013] As shown in FIG. 1 , the attachment 4 used in the cable trough 1 is attached between the trough body 2 and the lid 3. The attachment 4 includes a pair of sidewall plates 41 extending in the vertical direction and a top plate 42 connecting the pair of sidewall plates 41. By attaching the attachment 4 between the trough body 2 and the lid 3, the internal space of the cable trough 1 can be expanded, thereby increasing the capacity of the cable trough 1. Because the pair of sidewall plates 41 are connected to each other by the top plate 42, the distance between the pair of sidewall plates 41 is unlikely to increase even if an outward force is applied to the inner surfaces of the sidewall plates 41. Therefore, with the cable trough 1 to which the attachment 4 according to this embodiment is attached, the lid 3 is unlikely to fall off even when items are stored inside.

[0014] As shown in Figure 2, the trough body 2 has a storage section S1 for storing items. The trough body 2 includes a bottom wall 21 and a plurality of (here, a pair of) side walls 22. The trough body 2 extends in the longitudinal direction from a first end to a second end and has a uniform cross-sectional shape in the longitudinal direction. The bottom wall 21 is the lowermost plate. The maximum length of the bottom wall 21 in the longitudinal direction is longer than the maximum length of the bottom wall 21 in the width direction.

[0015] The pair of side walls 22 protrude upward from both widthwise ends of the bottom wall 21. The bottom wall 21 and the pair of side walls 22 are integrally formed, so that the trough body 2 is formed with a generally U-shaped cross section. An opening surface (hereinafter sometimes referred to as "upper opening surface") is formed between the upper end surfaces of the pair of side walls 22. Items are stored inside the trough body 2 through the upper opening surface.

[0016] The lid 3 closes the upper opening of the trough body 2 in an openable and closable manner. The lid 3 is formed in a plate shape. The widthwise dimension of the lid 3 (hereinafter referred to as the "width dimension") is the same throughout the entire length and is equivalent to the dimension from one outer surface to the other outer surface of the trough body 2 in the widthwise direction. In this specification, "equivalent" does not only mean "matching" in the strict sense, but also includes what can be considered the same. A convex portion 31 that protrudes downward is formed in the center of the widthwise direction of the lid 3. When the lid 3 is attached to the trough body 2, the lower surfaces 32 on both sides of the convex portion 31 in the widthwise direction face the upper end surfaces of the pair of side walls 22, and the convex portion 31 fits between the pair of side walls 22. This allows the lid 3 to be positioned relative to the trough body 2 in the widthwise direction of the cable trough 1.

[0017] (Attachment 4) The attachment 4 is an accessory for increasing the capacity of the cable trough 1. As shown in FIG. 2, the attachment 4 includes a plurality of (here, a pair of) side wall plates 41 and a top plate 42. The attachment 4 may be installed together with the cable trough 1 after being attached to the cable trough 1, or may be attached to an existing cable trough 1 as an add-on. The attachment 4 makes it possible to increase the capacity using a conventional cable trough 1.

[0018] (Side wall plate 41) The side wall plate 41 is a member that extends the side wall 22 of the cable trough 1 in the upward direction. As shown in Fig. 2, the side wall plate 41 includes a side wall main body 413, a lower horizontal piece 411, a vertical piece 412, and an upper horizontal piece 414. In this embodiment, the upper horizontal piece 414, the side wall main body 413, the lower horizontal piece 411, and the vertical piece 412 are integrally formed by bending, for example, by press working.

[0019] The sidewall main body 413 extends from the upper end surface of the sidewall 22 to the lid 3. In other words, the sidewall main body 413 is disposed between the sidewall 22 and the lid 3 and extends in the up-down direction. In this embodiment, the sidewall main body 413 is a flat surface along a vertical plane. The sidewall main body 413 is preferably located on the same plane as the outer surface of the sidewall 22, and is preferably formed flush with the outer surface. However, the sidewall main body 413 may be inclined with respect to the vertical plane.

[0020] The lower horizontal piece 411 protrudes inward in the width direction from the lower end of the side wall main body 413. The lower surface of the lower horizontal piece 411 faces the upper end surface of the side wall 22. In this embodiment, the lower horizontal piece 411 is perpendicular to the side wall main body 413. It is preferable that the lower horizontal piece 411 is continuous over the entire length of the side wall main body 413 in the longitudinal direction. By having the lower horizontal piece 411 continuous over the entire length of the side wall main body 413 in the longitudinal direction, the side wall main body 413 can be stably erected relative to the side wall 22, and the rib effect can increase the rigidity of the side wall main body 413. The lower horizontal piece 411 may be provided on a portion of the side wall main body 413 in the longitudinal direction.

[0021] The vertical piece 412 protrudes downward from the lower horizontal piece 411. It is preferable that the vertical piece 412 protrudes downward from the inner end of the lower horizontal piece 411 in the width direction. By providing the vertical piece 412 at the end of the lower horizontal piece 411, it is less likely to hinder the storage of cables in the cable trough 1. The outer surface of the vertical piece 412 in the width direction faces the inner surface of the side wall 22, as shown in FIG. 3. It is preferable that the vertical piece 412 is close to the inner surface of the side wall 22, and at least a portion of it may be in contact with it. It is also preferable that the vertical piece 412 is continuous over the entire length of the attachment 4 in the longitudinal direction. This can increase the rigidity of the side wall main body 413 by using a rib effect.

[0022] As shown in FIG. 2, the upper horizontal piece 414 protrudes inward in the width direction from the upper end of the side wall main body 413. A plurality of screw holes are formed in the upper horizontal piece 414. The top plate 42 is attached to the upper horizontal piece 414 by threading screws 5 into the screw holes. As a result, the upper horizontal pieces 414 of the pair of side wall plate bodies 41 are connected to each other by the top plate 42. It is preferable that the upper horizontal piece 414 is continuous over the entire length of the attachment 4. This provides a rib effect, which can increase the rigidity of the side wall main body 413. However, the upper horizontal piece 414 may be formed partially in the length direction to correspond to the screw holes.

[0023] The material of the side wall plate 41 is not particularly limited, and examples thereof include steel plate, steel, aluminum alloy, stainless steel alloy, titanium, etc. However, the side wall plate 41 is not limited to a metal plate, and may be made of, for example, synthetic resin, carbon, wood, FRP (Fiber Reinforced Plastics), ceramic, etc.

[0024] (Tabletop 42) The top plate 42 connects the multiple side wall plates 41. The top plate 42 is removably attached to the upper horizontal piece 414. The top plate 42 is attached to the upper horizontal piece 414 by threading screws passed through through holes in the top plate 42 into screw holes in the upper horizontal piece 414. When the lid 3 is attached, the top plate 42 faces the underside of the lid 3, as shown in FIG. 3. As shown in FIG. 4, the top plate 42 includes a pair of mounting portions 423, a pair of hanging portions 422, and a top plate main body 421. The pair of mounting portions 423, the pair of hanging portions 422, and the top plate main body 421 are integrally formed, for example, by bending processing such as pressing.

[0025] As shown in FIG. 2, the mounting portion 423 is parallel to the upper horizontal piece 414 and overlaps the upper horizontal piece 414. The lower surface of the mounting portion 423 faces the upper surface of the upper horizontal piece 414. A plurality of through holes are formed in the mounting portion 423. As described above, the top plate 42 is attached to the upper horizontal piece 414 by threading screws passed through the through holes into the screw holes in the upper horizontal piece 414. The mounting portion 423 may also be attached so as to overlap the lower surface of the upper horizontal piece 414.

[0026] 4, hanging portion 422 protrudes downward from the inner end in the width direction of mounting portion 423. Hanging portion 422 is perpendicular to mounting portion 423. Providing hanging portion 422 can increase the rigidity compared to top plate 42 that does not have hanging portion 422.

[0027] Top plate main body 421 connects the lower ends of hanging parts 422. Top plate main body 421 is formed in a flat shape. As shown in FIG. 3, top plate main body 421 faces the lower surface of protrusion 31 of lid 3. Top plate main body 421 and protrusion 31 may be positioned with a gap between them or may be in contact with each other.

[0028] The top plate main body 421 has a plurality of openings 424. The plurality of openings 424 are formed at a regular pitch and spaced apart in the longitudinal direction. In this embodiment, each opening 424 is formed in a rectangular shape, allowing cables to be passed through. The minimum length of one side of the opening 424 is preferably 50 mm or more, more preferably 60 mm or more, and even more preferably 70 mm or more. On the other hand, the minimum length of one side of the opening 424 is preferably 100 mm or less, and more preferably 90 mm or less. With this configuration, cables can be introduced into the cable trough 1 through the openings 424.

[0029] In the tabletop main body 421, the portion between adjacent openings 424 (hereinafter referred to as the grip portion 425) preferably has a certain width or more. This allows an operator to grasp the portion between adjacent openings 424 and carry the tabletop 42. The length of the grip portion 425 in the direction in which the adjacent openings 424 are lined up (here, the length direction) (i.e., the width of the grip portion 425) is preferably 20 mm or more, and more preferably 25 mm or more. On the other hand, the width of the grip portion 425 is preferably 50 mm or less, more preferably 40 mm or less, and even more preferably 30 mm or less. This configuration makes it easy for an operator to grasp the grip portion 425, and the grip portion 425 is less likely to deform when grasped.

[0030] Top plate 42 has a recess into which protrusion 31 fits. The recess is recessed below an imaginary plane including mounting portion 423, and in this embodiment, is composed of a pair of hanging portions 422 and top plate main body 421. Because top plate 42 has the recess, when lid 3 is attached above top plate 42, protrusion 31 fits into the recess as shown in FIG. 3 . This restricts movement of protrusion 31 in the width direction by the pair of hanging portions 422, so that lid 3 can be positioned with respect to attachment 4 in the width direction of cable trough 1.

[0031] <Modification> The above-described embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. Modifications of the embodiment will be described below. The modifications described below can be applied in appropriate combinations.

[0032] The top plate 42 according to the above embodiment has four openings 424, but may have two openings 424, for example, as shown in Fig. 5. A gripping portion 425 is formed between adjacent openings 424. Furthermore, five or more openings 424 may be provided.

[0033] Although the opening 424 according to the above embodiment is formed in a rectangular shape, it may be formed in a triangular, circular, elliptical, slit-like shape, or the like.

[0034] Although the side wall main body 413 according to the above embodiment is made of a metal plate, it may be made of, for example, a square tube. Also, the side wall main body 413 may be made of a honeycomb structure.

[0035] The outer surface of the side wall main body 413 is located on the same plane as the outer surface of the side wall 22 of the trough main body 2, but it may be located more inward than the outer surface of the side wall 22 of the trough main body 2. In this case, the vertical piece 412 may be arranged to face the outer surface of the side wall 22.

[0036] Each side wall plate 41 does not have to be flat, but may be curved.

[0037] In the top plate 42 according to the above embodiment, the top plate main body 421 is positioned below the attachment portion 423, but when a lid 3 without a protrusion 31 is used, the top plate may be configured in a flat plate shape.

[0038] The side wall main body 413 may have an opening window formed therein through which the inside of the cable trough 1 can be seen. The opening window may penetrate the side wall main body 413, or a transparent window may be fitted in. Furthermore, the side wall main body 413 itself may be made of a transparent material.

[0039] The material of the attachment is not limited to metal, but may be, for example, synthetic resin, carbon, etc. Furthermore, the processing method of the attachment is not limited to bending, but may be, for example, forging, casting, extrusion, injection molding, cast molding, etc.

[0040] Although the trough body 2 has a pair of parallel side walls 22, it may have three or more side walls 22. For example, the trough body may have three side walls 22 or four side walls 22. A trough body having three side walls 22 is formed in a generally triangular shape in plan view and is provided at a three-way intersection where the trough body of the above embodiment is connected to each vertex. A trough body having four side walls 22 is formed in a quadrangular shape in plan view and is provided at a four-way intersection where the trough body of the above embodiment is connected to each vertex. The attachment 4 has side wall plates 41 attached to each of the three or more side walls 22, and the three or more side wall plates 41 are connected to each other by a top plate 42.

[0041] The bottom wall 21 of the trough body 2 may have a slope over its entirety, or only a portion of the bottom wall 21 may have a slope.

[0042] (summary) As described above, the attachment 4 for the cable trough 1 according to the first aspect is an attachment 4 that is attached to the cable trough 1 having the trough body 2 having the bottom wall 21 and a plurality of side walls 22, and the lid 3 that closes the upper opening surface of the trough body 2, to increase the volume of the cable trough 1. The attachment 4 is attached to the plurality of side walls 22 of the trough body 2 and includes a plurality of side wall plates 41 that extend in the height direction of the trough body 2, and a top plate 42 that connects the plurality of side wall plates 41 and faces the lower surface of the lid 3.

[0043] According to this aspect, by attaching the attachment 4 between the trough body 2 and the lid 3, the internal space of the cable trough 1 can be expanded, thereby increasing the capacity of the cable trough 1. Because the multiple side wall plates 41 are connected to each other by the top plate 42, the distance between the multiple side wall plates 41 is unlikely to increase even when force is applied to the inner surfaces of the side wall plates 41. Therefore, with the cable trough 1 to which the attachment 4 according to this embodiment is attached, the lid 3 is unlikely to fall off even when items are stored inside.

[0044] In the attachment 4 for the cable trough 1 according to the second aspect, in the first aspect, the top plate 42 is removably attached to the multiple side wall plates 41. According to this aspect, by removing the top plate 42, cables can be easily accommodated in the cable trough 1. Furthermore, even if multiple cables are located above the upper ends of the side walls 22 of the trough body 2 in the cable trough 1, by removing the top plate 42, additional cables can be accommodated from above while the cables are supported by the multiple side wall plates 41.

[0045] In the attachment 4 of the cable trough 1 according to the third aspect, in the first or second aspect, each side wall plate 41 has a lower horizontal piece 411 that rests on the upper end surface of the side wall 22 of the trough body 2, and a vertical piece 412 that protrudes downward from the lower horizontal piece 411 and faces the side surface of the side wall 22. According to this aspect, the vertical piece 412 can restrict movement of the side wall plate 41, thereby reducing the likelihood of the side wall plate 41 falling off the side wall 22.

[0046] In the attachment 4 for the cable trough 1 according to the fourth aspect, in the third aspect, the vertical piece 412 is configured to face the inner surface of the side wall 22 of the trough body 2. According to this aspect, even if the cable pushes the side wall plate 41 from the inside to the outside, the vertical piece 412 hits the side wall 22 of the trough body 2, preventing the side wall plate 41 from falling off the side wall 22. Furthermore, because the vertical piece 412 is hidden inside the trough body 2, it is possible to reduce damage to the appearance.

[0047] In the attachment 4 of the cable trough 1 according to the fifth aspect, in the third or fourth aspect, the vertical piece 412 is continuous over the entire length of the side wall plate body 41. According to this aspect, the rigidity of the side wall body 413 can be increased by the rib effect.

[0048] In the attachment 4 of the cable trough 1 according to the sixth aspect, in any one of the first to fifth aspects, an opening 424 through which a cable can pass is formed in the portion of the top plate 42 facing the underside of the lid 3. According to this aspect, a cable can be introduced into and taken out of the cable trough 1 through the opening 424.

[0049] The attachment 4 for the cable trough 1 according to the seventh aspect is the same as the sixth aspect, but includes a plurality of openings 424, which are formed at intervals in the longitudinal direction of the cable trough 1. According to this aspect, by removing the lid 3, the condition of the cables in the cable trough 1 can be visually confirmed through the openings 424, while a decrease in the strength of the top plate 42 can be suppressed.

[0050] In the attachment 4 of the cable trough 1 according to the eighth aspect, the portion between the adjacent openings 424 in the seventh aspect is the gripping portion 425. According to this aspect, the worker can carry the top plate 42 by grasping the gripping portion 425, which improves workability.

[0051] In the attachment 4 for the cable trough 1 according to the ninth aspect, in any one of the first to eighth aspects, the top plate 42 has a recess into which the protrusion 31 protruding from the underside of the lid 3 fits. In the width direction of the cable trough 1, the inner surface of the recess is configured to face the outer surface of the protrusion 31. According to this aspect, the movement of the protrusion 31 in the width direction is restricted by the pair of hanging parts 422, so that the lid 3 can be positioned relative to the attachment 4 in the width direction of the cable trough 1.

[0052] The cable trough 1 having an attachment 4 according to the tenth aspect includes a trough body 2 having a bottom wall 21 and a plurality of side walls 22, a cable trough 1 having a lid 3 that closes the upper opening surface of the trough body 2, and an attachment 4 that is attached between the trough body 2 and the lid 3 and that increases the volume of the cable trough 1. The attachment 4 has a plurality of side wall plates 41 that are attached to the plurality of side walls 22 of the trough body 2 and extend in the height direction of the trough body 2, and a top plate 42 that connects the plurality of side wall plates 41 and faces the underside of the lid 3.

[0053] According to this embodiment, it is possible to expand the internal space of the cable trough 1 and increase the capacity of the cable trough 1. Because the side wall plates 41 are connected to each other by the top plate 42, the distance between the side wall plates 41 is unlikely to increase even when force is applied to the inner surfaces of the side wall plates 41. Therefore, according to the cable trough 1 to which the attachment 4 according to this embodiment is attached, the lid 3 is unlikely to fall off even when items are stored inside.
