[0001] The present invention relates to a cable rack closing structure for closing an open portion of an accommodation area of a cable rack with a cover member, and an attachment member used for constituting the closing structure.

Background Art

[0002] Conventionally, as a method of fixing a cover of a cable rack to the cable rack, there is a method of pressing it with a clamp member from above the cover and fixing the clamp member to the cable rack. For example, in Patent Document 1, as a member for attaching a clamp member to a cable rack, a hook bolt having a bolt portion formed at one end and a hook-shaped engaging portion formed at the other end is used. At this time, while engaging the engaging portion of the hook bolt with the cable rack, the bolt portion is inserted into an insertion hole provided in the clamp member and screwed with a fixing nut. Thereby, the clamp member is fixed to the cable rack via the hook bolt.

Patent Documents

[0003] <​​​​​​​​​​​​Incidentally, the theft of cables stored in cable racks has become a problem in recent years. In Patent Document 1, the clamp member is fixed with a linear hook bolt, so if it is cut with a grinder or the like, the cover can be easily removed. With the cover removed, the cables are exposed from the cable rack, making them easy to steal. As a countermeasure, for example, making the hook bolt thicker would provide some protection against cutting, but with the clamp member mounting method in Patent Document 1, even when the clamp member is attached to the cable rack, it is possible to slide the clamp member, along with the hook bolt, in the longitudinal direction of the cable rack (the longitudinal direction of the main beam of the cable rack). In this case, the cover can be easily removed, so there is a need for a mounting structure that firmly fixes the clamp member and makes cable theft difficult.

[0005] Therefore, the present invention aims to provide a mounting member that can firmly fix a clamp member for sandwiching a cover to a cable rack to the cable rack, and a closing structure for a cable rack in which the mounting member is used. [Means for solving the problem]

[0006] (1) The mounting member of the present invention, provided to solve the above-mentioned problems, is a mounting member used to constitute a cable rack closing structure in a cable rack having a cable storage area, wherein the cable rack closing structure comprises a clamp member that clamps the cover member onto the cable rack, the cable rack is formed to extend in the longitudinal direction and comprises a pair of main beams arranged opposite each other, a storage area formed between the pair of main beams, and a child member provided with respect to the main beams so as not to move in the longitudinal direction at a position further back in the depth direction of the storage area than the opening, the mounting member comprises a fastening portion fastened to the clamp member side, an engaging portion that engages with the cable rack side, and a main body portion connecting the fastening portion and the engaging portion, wherein, when the engaging portion is engaged with the cable rack side, the movement of the mounting member in the longitudinal direction of the main beam can be inhibited by interference with the child member.

[0007] With this configuration, when the engaging portion is engaged with the cable rack, the longitudinal movement of the main beam in the mounting member is hindered by interference between the mounting member and the sub-member. In this way, the longitudinal movement of the clamp member relative to the cable rack can be restricted, and therefore, the mounting member of the present invention can fix the clamp member more firmly to the cable rack compared to conventional clamp members.

[0008] Furthermore, the longitudinal movement of the clamp member can also be restricted by fixing the mounting member to the cable rack with screws or the like. However, the mounting member of the present invention can restrict the longitudinal movement of the clamp member by the mounting member without using screws, thus allowing the clamp member to be firmly fixed to the cable rack with a simple configuration.

[0009] (2) The mounting member of the present invention described above is a mounting member used to constitute a cable rack closure structure in a cable rack having a cable storage area, wherein the cable rack closure structure comprises a clamp member that clamps the cover member onto the cable rack, the cable rack comprises a pair of main beams extending in the longitudinal direction and spaced apart in the width direction, the storage area formed between the pair of main beams, and a sub-member provided so as to bridge the pair of main beams and positioned further back in the depth direction of the storage area than the opening, and provided so as to be immovable in the longitudinal direction relative to the main beams, the mounting member comprises a fastening portion fastened to the clamp member side and an engagement portion on the cable rack side The mounting member comprises an engaging portion and a main body portion connecting the fastening portion and the engaging portion, wherein the main body portion is positioned to face the longitudinally extending side surface of one of the main girders, and the engaging portion is provided by bending from the main body portion to engage with the inner side in the depth direction of one of the main girders, and a convex movement restricting portion is formed at the tip of the engaging portion, projecting in the thickness direction of the child member, and the movement restricting portion comprises a first movement restricting portion positioned on one longitudinal side of the child member and a second movement restricting portion positioned on the other longitudinal side of the child member, and it is preferable that, when the engaging portion is engaged with the cable rack side, the mounting member is configured to restrict movement of the mounting member in the longitudinal direction of the main girder by interference between the movement restricting portion and the child member.

[0010] The mounting member of the present invention, when fastened to the clamp member at the fastening portion, engages with the rear side (rear side in the depth direction of the storage area) of the cable rack at the engaging portion. As a result, the clamp member's movement in the depth direction of the storage area relative to the cable rack is restricted by the engaging portion. Furthermore, a convex movement restricting portion (first movement restricting portion, second movement restricting portion) is formed at the tip of the engaging portion of the mounting member, projecting in the thickness direction of the sub-member. Due to the interference between both movement restricting portions and the sub-member, the clamp member's movement in both the longitudinal direction of the main beam relative to the cable rack is restricted. In this way, the mounting member of the present invention can restrict the movement of the clamp member in both the depth direction and the longitudinal direction relative to the cable rack, and therefore, compared to conventional mounting members, the clamp member can be fixed more firmly to the cable rack.

[0011] Furthermore, the longitudinal movement of the clamp member can also be restricted by fixing the mounting member to the cable rack with screws or the like. However, the mounting member of the present invention can restrict the longitudinal movement of the clamp member by movement restricting parts (first movement restricting part, second movement restricting part) without using screws, so the clamp member can be firmly fixed to the cable rack with a simple configuration.

[0012] (3) The sub-member is preferably a sub-girder that extends in a width direction intersecting the main girder and is provided so as not to move in the longitudinal direction relative to the main girder.

[0013] In this way, the mounting member of the present invention can prevent the clamp member from moving in the longitudinal direction relative to the cable rack by interference with the sub-girders of the cable rack, and the clamp member can be firmly fixed to the cable rack.

[0014] (4) The engaging portion has a convex movement restricting portion that protrudes in the thickness direction of the child member, and the movement restricting portion can obstruct the movement of the mounting member in the longitudinal direction of the main girder by interfering with the child member.

[0015] In this way, the mounting member of the present invention can easily cause the mounting member and the sub-member to interfere with each other through the movement restricting portion, and as a result, the longitudinal movement of the clamp member relative to the cable rack can be easily inhibited.

[0016] (5) The movement restricting portion may include a first movement restricting portion disposed on one side in the longitudinal direction relative to the child member, and a second movement restricting portion disposed on the other side in the longitudinal direction relative to the child member.

[0017] In this manner, the mounting member of the present invention engages with the cable rack with the sub-member sandwiched between the first and second movement restricting portions. As a result, the mounting member of the present invention can restrict the longitudinal movement of the clamping member relative to the cable rack (movement to both sides in the longitudinal direction).

[0018] (6) The engaging portion is preferably attached so as to straddle the child member in the longitudinal direction, thereby engaging with the child member.

[0019] In this way, the mounting member of the present invention is more easily able to interfere with the sub-member through the engaging portion.

[0020] (7) The engaging portion is preferably configured to engage with the main girder while also engaging with the child member.

[0021] In this way, the mounting member of the present invention can easily hinder the movement of the clamp member relative to the main beam and the movement of the clamp member relative to the child member.

[0022] (8) The clamping member is disposed opposite to the cover member with a predetermined interval therebetween, and has a strip-shaped opposing wall whose longitudinal direction is disposed in a direction intersecting the pair of main beams, two side walls extending from both ends in the short direction of the opposing wall toward the cover member side, and lip portions provided on each of the two side walls and extending from the tip of the side wall toward the opposing side wall. The fastening portion is formed in a size that can be disposed in the internal space of the clamping member surrounded by the opposing wall, the side walls, and the lip portions, while being formed in a size that cannot pass between the lip portions. The connection portion between the fastening portion and the main body portion is formed in a size that can be disposed between the lip portions. The attachment member is configured such that the fastening portion is disposed in the internal space, the connection portion is disposed in the gap between the lip portions, and the fastening portion of the attachment member is fastened to the opposing wall of the clamping member with a fastening member, so that the clamping member is fixed to the attachment member.

[0023] In this case, the fastening portion of the attachment member is formed in a size that cannot pass between the lip portions. Therefore, once the fastening portion is disposed in the internal space of the clamping member, the fastening portion is locked to the wall surface of the internal space of the clamping member, and the attachment member is in a temporarily fixed state. By setting it to such a state, the attachment member of the present invention can improve the workability related to fastening to the clamping member.

[0024] (9) The attachment member is preferably formed of a plate-shaped member.

[0025] By doing so, the attachment member of the present invention can increase the contact area with a cutting tool such as a grinder when cutting is attempted, compared to a conventional linear hook member. Therefore, it can be expected that when cutting, the stress acting from the cutting tool is dispersed and it becomes difficult to be cut.

[0026] (10) The main beam has a side surface extending in the longitudinal direction, and the attachment member is preferably attached so that at least the main body portion is formed in a plate shape and faces the side surface of the main beam.

[0027] By doing so, when an attempt is made to cut the mounting member of the present invention, the area accessible to a cutting tool such as a grinder can be reduced, and as a result, the cutting operation can be made physically difficult. Further, the mounting member of the present invention can easily bring the main body portion into contact with the side surface of the parent beam. When brought into contact in this way, it can be expected that when an attempt is made to cut, the stress acting from the cutting tool is further dispersed, making it even more difficult to cut.

[0028] (11) In the mounting member according to the present invention, an adhesive layer may be disposed between the fastening portion and the clamping member, and the fastening portion and the clamping member may be adhered by the adhesive layer.

[0029] By doing so, even if the fastening member that fastens to the clamping member of the mounting member of the present invention is cut by a cutting tool such as a grinder, the mounting member and the clamping member can still be fixed by the adhesive layer. Therefore, the mounting member of the present invention can further make it difficult to remove the clamping member from the cable rack.

[0030] (12) The cable rack closure structure of the present invention is a cable rack closure structure in which a cable storage area is provided, and an open portion of the storage area is closed by a cover member, comprising: a clamp member that clamps the cover member onto the cable rack; and a mounting member that attaches the clamp member to the cable rack, wherein the cable rack is formed to extend in the longitudinal direction and comprises: a pair of main beams arranged opposite each other; a storage area formed between the pair of main beams; and a child member provided on the main beams at a position further back in the depth direction of the storage area than the open portion, so as to be immovable in the longitudinal direction, wherein the mounting member comprises: a fastening portion that is fastened to the clamp member side; an engaging portion that engages with the cable rack side; and a main body portion that connects the fastening portion and the engaging portion, wherein, when the engaging portion is engaged with the cable rack side, the movement of the mounting member in the longitudinal direction of the main beam can be obstructed by interference with the child member.

[0031] The cable rack closure structure of the present invention is configured such that, when the engaging portion is engaged with the cable rack, the movement of the mounting member in the longitudinal direction of the main beam is inhibited by interference between the mounting member and the sub-member. In this way, the longitudinal movement of the clamp member relative to the cable rack can be restricted, and therefore, the cable rack closure structure of the present invention can firmly fix the clamp member to the cable rack compared to conventional cable rack closure structures.

[0032] Furthermore, the longitudinal movement of the clamp member can also be restricted by fixing the mounting member to the cable rack with screws or the like. However, the cable rack closure structure of the present invention can restrict the longitudinal movement of the clamp member by the mounting member without using screws, thus allowing the clamp member to be firmly fixed to the cable rack with a simple configuration. [Effects of the Invention]

[0033] According to the present invention, it is possible to realize a mounting member that can firmly fix a clamp member for sandwiching a cover to a cable rack to the cable rack, and a closing structure for a cable rack in which the mounting member is used. [Brief explanation of the drawing]

[Figure 8] This is a perspective view showing other variations of the mounting component. [Modes for carrying out the invention]

[0035] The present invention relates to an attachment member 40 for attaching a clamp member 30 to a cable rack 1 that houses a cable K, and a cable rack closing structure that uses the attachment member 40 to close the open portion 10 of the storage area A (the area for storing the cable K) of the cable rack 1 with a cover member 20. The clamp member 30 presses down on the cover member 20 that closes the open portion 10 of the cable rack 1 from above, and clamps the cover member 20 against the cable rack 1. The cable rack 1, cover member 20, and clamp member 30 that constitute the attachment structure will be described below, followed by a description of the attachment member 40 for attaching the clamp member 30 to the cable rack 1.

[0036] Furthermore, in the following, the mounting structure of the present invention may be described using the longitudinal direction F of the main beam 2, the width direction P of the pair of main beams 2 which intersects the longitudinal direction F, and the height direction H of the main beam 2 which corresponds to the thickness of the cable rack 1, as shown in Figure 1. In addition, in the height direction H in Figure 1, the upward direction may be described as "up" and the downward direction as "down". Furthermore, this height direction corresponds to the "depth direction of the storage area A" in the present invention. Also, the longitudinal direction F of the main beam 2 corresponds to the longitudinal direction of the cable rack 1 itself.

[0037] As shown in Figure 1, the cable rack 1 comprises a pair of main girders 2 extending in the longitudinal direction F and arranged parallel to each other at a predetermined distance apart, and a plurality of sub-girders 3 provided to bridge the two main girders 2. The plurality of sub-girders 3 are arranged at approximately equal intervals along the longitudinal direction F of the main girders 2 and are fixed immovably to the lower end of the main girders 2 (the end on the far side in the depth direction as described above). As a result, the cable rack 1 is formed in a ladder shape as a whole, and a storage area A for accommodating cables K is formed between the two main girders 2. The cable rack 1 also has an open section 10 formed by opening the top, and is configured so that cables K can be placed in the storage area A from this open section 10. A cover member 20 is placed on the cable rack 1 to close this open section 10.

[0038] The cover member 20 is a plate-shaped member with a U-shaped cross-section, and is positioned to cover the open portion 10 of the cable rack 1 and a portion of the side surface of the pair of main girders 2 (the side surface 2a located on the outside in the width direction P of the main girders 2). The side surface 2a of the main girders 2 is provided to extend in the longitudinal direction F of the main girders 2 (cable rack 1).

[0039] As described above, the clamp member 30 presses the cover member 20 against the main beam 2 side of the cable rack 1 from above. The clamp member 30 is attached to the cable rack 1 using the mounting member 40, which will be described later, thereby restricting the upward movement of the cover member 20.

[0040] Specifically, as shown in Figure 4, the clamp member 30 is formed by opposing walls 31, side walls 32, and lip portion 33.

[0041] When attached to the cable rack 1, the opposing wall 31 is formed in a strip shape with the width P of the pair of main girders 2 as its longitudinal direction, and is positioned opposite the cover member 20 at a predetermined distance. Side walls 32 extending toward the cover member 20 are positioned at each of the short ends of the opposing wall 31. Both side walls 32 extend along the entire longitudinal direction of the opposing wall 31.

[0042] Lip portions 33 are formed at the tips (lower ends) of both side walls 32, extending toward the opposing side wall 32. The tips of the lip portions 33 are bent upward, and their cross-sectional shape is L-shaped.

[0043] As shown in Figure 1, the length of the clamp member 30 (the length in the longitudinal direction of the opposing wall 31) is larger than the width between the main girders 2, and both ends of the clamp member 30 in the longitudinal direction (width direction P) protrude from the cable rack 1. At both ends of the opposing wall 31 (the parts that protrude from the cable rack 1), elongated screw holes 31a are formed through which screws 5 for fastening to the mounting member 40 are inserted. The clamp member 30 is sometimes referred to as a C-channel material.

[0044] Next, with reference to Figures 2 to 4, the mounting member 40 for attaching the clamp member 30 to the cable rack 1 will be described.

[0045] As shown in Figure 2, the mounting member 40 has a main body portion 41, an engaging portion 42, and a fastening portion 43. One mounting member 40 is provided at each end of the clamp member 30, and is used as a member to attach both ends of the clamp member 30 to the cable rack 1 (a pair of main girders 2).

[0046] The main body portion 41 is the part that is positioned opposite the outer side surface 2a (see Figure 4) in the width direction P of the corresponding main beam 2 when the clamp member 30 is attached to the cable rack 1. The main body portion 41 is the part that connects the fastening portion 43 and the engaging portion 42 and extends in the height direction H of the main beam 2. Specifically, the main body portion 41 is formed in the shape of a rectangular plate with its longitudinal direction parallel to the height direction of the main beam 2 and its short direction parallel to the longitudinal direction F of the main beam 2. In addition, the main body portion 41 is formed to be approximately the same size as the height of the main beam 2 in the height direction H of the main beam 2.

[0047] The engaging portion 42 is the part that engages with the lower end of the corresponding main girder 2 when the clamp member 30 is attached to the cable rack 1. As shown in Figures 1, 2, and 4, the engaging portion 42 is provided by bending from the lower end of the main body portion 41 inward between the pair of main girder 2 (inward direction of the pair of main girder 2 in the width direction P). That is, the engaging portion 42 is formed to extend inward from the lower end of the main body portion 41 in the width direction P between the pair of main girder 2. In addition, the engaging portion 42 is formed in a rectangular plate shape, similar to the main body portion 41.

[0048] The tip of the engaging portion 42 (the end in the inner direction in the width direction P) is located slightly inward from the corresponding main girder 2, and two movement restricting portions 42a are formed at this tip. The movement restricting portions 42a are provided to restrict the movement of the clamp member 30 in the longitudinal direction F of the main girder 2 when the clamp member 30 is attached to the cable rack 1 by the mounting member 40.

[0049] The movement restricting portion 42a is formed in a convex shape that protrudes in the thickness direction of the sub-girder 3. That is, the movement restricting portion 42a is provided by bending upward from the tip of the engaging portion 42. In other words, the movement restricting portion 42a extends upward in the height direction H of the main girder 2 from the tip of the engaging portion 42. Furthermore, the movement restricting portions 42a are arranged at both ends of the main girder 2 in the longitudinal direction F at the tip of the engaging portion 42, and both movement restricting portions 42a are arranged with a predetermined distance between them in the longitudinal direction F. The distance between the movement restricting portions 42a is slightly larger than the width of the sub-girder 3 in the short direction, and the configuration allows a predetermined sub-girder 3 to be placed between the movement restricting portions 42a.

[0050] Thus, the engaging portion 42 is installed so as to straddle a predetermined sub-girder 3 in the longitudinal direction F, thereby engaging not only with the main girder 2 but also with the predetermined sub-girder 3.

[0051] The fastening portion 43 is the part fastened with a clamp member 30 and a screw 5. As shown in Figures 1, 2, and 4, the fastening portion 43 is connected to the upper end of the main body portion 41 and is bent outwards from the upper end of the main body portion 41 toward the outside of the main beam 2 in the width direction P. More specifically, the fastening portion 43 is connected to the main body portion 41 via a connecting portion 44 and extends outwards from the upper end of the connecting portion 44 toward the outside of the main beam 2 in the width direction P.

[0052] The connecting portion 44 is a narrow, plate-like portion that extends from the upper end of the main body portion 41 along the main body portion 41. As shown in Figure 2, the width W1 of the connecting portion 44 (the width F in the longitudinal direction of the main beam 2) is narrower than the width W2 of the main body portion 41 and the width W3 of the fastening portion 43. The fastening portion 43 is formed in a rectangular plate shape and has screw holes 43a for fastening with screws 5. Female screw grooves are formed on the inner circumferential surface of the screw holes 43a.

[0053] The mounting member 40 is made of a metal plate such as stainless steel or aluminum. One example of how to manufacture the mounting member 40 is to shape a single metal plate into a desired shape by punching or other means, and then bend it.

[0054] As shown in Figure 4, the width W3 of the fastening portion 43 of the mounting member 40 (width in the longitudinal direction F of the main beam 2) is smaller than the width W5 of the opposing wall 31 of the clamp member 30 in the short direction (width in the longitudinal direction F of the main beam 2), while it is larger than the width W4 of the gap in the lip portion 33 of the opposing clamp member 30 (width in the longitudinal direction F of the main beam 2). The width W1 of the connecting portion 44 of the mounting member 40 (width in the longitudinal direction F of the main beam 2: Figure 2) is smaller than the width W4 of the gap in the lip portion 33 (width in the longitudinal direction F of the main beam 2).

[0055] As shown in Figure 4, when the clamp member 30 is attached to the cable rack 1, the fastening portion 43 of the mounting member 40 is positioned in the internal space S of the clamp member 30. The internal space S is a space surrounded by the opposing wall 31, two side walls 32, and two lip portions 33. The connecting portion 44 of the mounting member 40 is positioned in the gap between the opposing lip portions 33.

[0056] Furthermore, as shown in Figure 3, when the clamp member 30 is attached to the cable rack 1, a predetermined sub-girder 3 is positioned between two movement restricting portions 42a provided on the engagement portion 42 of the mounting member 40. That is, one movement restricting portion 42a is positioned on one side of the predetermined sub-girder 3 in the longitudinal direction F, and the other movement restricting portion 42a is positioned on the other side of the predetermined sub-girder 3 in the longitudinal direction F. Each sub-girder 3 is fixed to the main girder 2 with screws or the like. Therefore, when the clamp member 30 is attached to the cable rack 1, even if one tries to move the clamp member 30 in the longitudinal direction F of the main girder 2, the two movement restricting portions 42a will hit the sub-girders 3 and prevent movement. Thus, the movement of the clamp member 30 relative to the cable rack 1 to both sides of the main girder 2 in the longitudinal direction F is restricted by the movement restricting portions 42a. Furthermore, when the clamp member 30 is attached to the cable rack 1, the engaging portion 42 of the mounting member 40 engages with the lower end of the main beam 2 of the cable rack 1 (the end on the far side in the depth direction of the storage area A), thereby restricting the upward movement of the clamp member 30 relative to the cable rack 1. Also, the downward movement of the clamp member 30 relative to the cable rack 1 is restricted by the cable rack 1 itself.

[0057] Next, an example of how to attach the clamp member 30 will be described. The clamp member 30 can be attached in the following way, for example. First, the cover member 20 is placed over the cable rack 1, which contains the cable K, from above. Then, with a predetermined sub-girder 3 positioned between the movement restricting portions 42a provided on the engaging portion 42 of the mounting member 40, the mounting member 40 is set on the cable rack 1 (main girder 2) so that the main body portion 41 of the mounting member 40 faces the side surface 2a of the main girder 2. Subsequently, the clamp member 30 with the lip portion 33 positioned downwards is placed on the cover member 20, and the clamp member 30 is slid in the width direction P from the end of the clamp member 30 so that the connecting portion 44 of the mounting member 40 passes through the gap in the lip portion 33 of the clamp member 30. This houses the fastening portion 43 of the mounting member 40 in the internal space S of the clamp member 30. As described above, the fastening portion 43 is formed to be wider than the gap (width W4: Figure 4) between the lip portions 33 of the clamp member 30. Therefore, when the fastening portion 43 is housed in the internal space S of the clamp member 30, the mounting member 40 is locked to the clamp member 30 and temporarily fixed in place. Next, the screw 5 is inserted from above the screw hole 31a of the clamp member 30 and fastened with the screw hole 43a (female thread) of the fastening portion 43 of the mounting member 40. This fastens the opposing wall 31 of the clamp member 30 and the fastening portion 43 of the mounting member 40 with the screw 5. By performing this series of attachments at both ends of the clamp member 30, the clamp member 30 is attached to the cable rack 1 while the cover member 20 is pressed against the cable rack 1.

[0058] (Mechanism of Action and Effects) The above describes one embodiment of the mounting structure for the clamp member 30 of the present invention. Next, the effects and advantages realized by the mounting structure for the clamp member 30 of this embodiment will be described below.

[0059] The mounting structure of the clamp member 30 described above has the following characteristic configuration. Therefore, the mounting structure of the clamp member 30 can achieve the following unique effects that cannot be achieved with conventional technology.

[0060] (a) The mounting member 40 of the present invention is used to configure a cable rack closing structure in a cable rack 1 having a cable K storage area A, wherein the opening 10 of the storage area A is closed by a cover member 20, and the cable rack closing structure comprises a clamp member 30 that clamps the cover member 20 with respect to the cable rack 1, and the cable rack 1 is formed to extend in the longitudinal direction F, and comprises a pair of opposing main beams 2, the storage area A formed between the pair of main beams 2, and the depth of the storage area A is greater than the opening 10 The mounting member 40 has a child member (child girder 3) that is fixed to the main girder 2 in the longitudinal direction F at a position on the far side (lower end), and the mounting member 40 has a fastening portion 43 that is fastened to the clamp member 30 side, an engaging portion 42 that engages to the cable rack 1 side, and a main body portion 41 that connects the fastening portion 43 and the engaging portion 42, and is characterized in that when the engaging portion 42 is engaged to the cable rack 1 side, the movement of the mounting member 40 in the longitudinal direction F of the main girder 2 can be prevented by interference with the child member (child girder 3).

[0061] With this configuration, when the engaging portion 42 is engaged with the cable rack 1, the movement of the main girder 2 in the longitudinal direction F on the mounting member 40 is hindered by interference between the mounting member 40 and the child member (child girder 3). In this way, the movement of the clamp member 30 in the longitudinal direction F relative to the cable rack 1 can be restricted, and therefore, the mounting member 40 of the present invention can fix the clamp member 30 more firmly to the cable rack 1 compared to the mounting member of a conventional clamp member.

[0062] Furthermore, the movement of the clamp member 30 in the longitudinal direction F can also be restricted by fixing the mounting member 40 to the cable rack 1 with screws or the like. However, the mounting member 40 of the present invention can restrict the movement of the clamp member 30 in the longitudinal direction F by the mounting member 40 without using screws, so the clamp member 30 can be firmly fixed to the cable rack 1 with a simple configuration.

[0063] (b) The mounting member 40 of the present invention described above is a mounting member 40 used to configure a cable rack closure structure in a cable rack 1 having a cable accommodation area A, wherein the cable rack closure structure comprises a clamp member 30 that clamps the cover member 20 onto the cable rack 1, the cable rack 1 comprises a pair of main beams 2 extending in the longitudinal direction F and spaced apart in the width direction P, the accommodation area A formed between the pair of main beams 2, and a child member (child beam 3) provided to bridge the pair of main beams 2 and positioned further back in the depth direction of the accommodation area A than the opening 10, such that its movement is restricted in the longitudinal direction F relative to the main beams 2, the mounting member 40 comprises a fastening portion 43 fastened to the clamp member 30 side, an engaging portion 42 that engages with the cable rack 1 side, and the fastening portion 43 The assembly comprises a main body portion 41 connecting the engaging portion 42, the main body portion 41 is positioned to face the side surface 2a of one of the main beams 2 that extends in the longitudinal direction F, the engaging portion 42 is provided by bending from the main body portion 41 and engages with the rear side of the one of the main beams 2 in the depth direction (height direction H), and a convex movement restricting portion 42a is formed at the tip of the engaging portion 42 that protrudes in the thickness direction of the child member (child beam 3), The movement restricting portion 42a comprises a movement restricting portion (first movement restricting portion 42a) positioned on one side of the longitudinal direction F relative to the child member (child girder 3), and a movement restricting portion (second movement restricting portion 42a) positioned on the other side of the longitudinal direction relative to the child member. It is preferable that, when the engaging portion 42 is engaged with the cable rack 1 side, the movement restricting portion 42a can restrict the movement of the mounting member 40 in the longitudinal direction F of the main girder 2 due to interference between the movement restricting portion 42a and the child member (child girder 3).

[0064] The mounting member 40 of the present invention, when fastened to the clamp member 30 at the fastening portion 43, engages with the rear side (the rear side in the depth direction of the storage area A) of the cable rack 1 at the engaging portion 42. As a result, the clamp member 30 is restricted from moving in the depth direction of the storage area A relative to the cable rack 1 by the engaging portion 42. In addition, a convex movement restricting portion 42a (first movement restricting portion, second movement restricting portion) is formed at the tip of the engaging portion 42 of the mounting member 40, protruding in the thickness direction of the child member (child beam 3). Due to the interference between both movement restricting portions 42a and the child member (child beam 3), the clamp member 30 is restricted from moving to both one side and the other side in the longitudinal direction F of the main beam 2 relative to the cable rack 1. In this way, the mounting member 40 of the present invention can restrict the movement of the clamp member 30 in both the depth direction (height direction H) and the longitudinal direction F relative to the cable rack 1, so that the clamp member 30 can be fixed more firmly to the cable rack 1 compared to conventional mounting members.

[0065] Furthermore, the movement of the clamp member 30 in the longitudinal direction F can also be restricted by fixing the mounting member 40 to the cable rack 1 with screws or the like. However, the mounting member 40 of the present invention can restrict the movement of the clamp member 30 in the longitudinal direction F by movement restricting parts 42a (first movement restricting part, second movement restricting part) without using screws, so the clamp member 30 can be firmly fixed to the cable rack 1 with a simple configuration.

[0066] (c) The child member may be a child girder 3 that extends in the width direction (width direction P) intersecting the main girder 2 and is provided in a manner that it cannot move in the longitudinal direction F relative to the main girder 2.

[0067] In this way, the mounting member 40 of the present invention can prevent the clamp member 30 from moving in the longitudinal direction F relative to the cable rack 1 by interference with the sub-girder 3 of the cable rack 1, and the clamp member 30 can be firmly fixed to the cable rack 1.

[0068] (d) The engaging portion 42 has a convex movement restricting portion 42a that protrudes in the thickness direction of the child member (child girder 3), and the movement restricting portion 42a can prevent the movement of the mounting member 40 in the longitudinal direction F of the main girder 2 by interfering with the child member (child girder 3).

[0069] In this way, the mounting member 40 of the present invention can be easily made to interfere with the sub-member (sub-girder 3) by the movement restricting portion 42a, and as a result, the movement of the clamp member 30 in the longitudinal direction F relative to the cable rack 1 can be easily hindered.

[0070] (e) The movement restricting portion 42a may have a movement restricting portion (first movement restricting portion 42a) arranged on one side of the longitudinal direction F with respect to the child member (child girder 3), and a movement restricting portion (second movement restricting portion 42a) arranged on the other side of the longitudinal direction F with respect to the child member (child girder 3).

[0071] In this manner, the mounting member 40 of the present invention engages with the cable rack 1 while the child member (child girder 3) is sandwiched between the first movement restricting portion 42a and the second movement restricting portion 42a. As a result, the mounting member 40 of the present invention can restrict the movement of the clamp member 30 in the longitudinal direction F relative to the cable rack 1 (movement to both sides of the longitudinal direction F, both to one side and the other side).

[0072] (f) The engaging portion 42 is preferably attached so as to straddle the sub-member (sub-girder 3) in the longitudinal direction F, thereby engaging with the sub-member (sub-girder 3).

[0073] In this way, the mounting member 40 of the present invention can easily interfere with the sub-member (sub-girder 3) by the engaging portion 42.

[0074] (g) The engaging portion 42 is preferably configured to engage with the main girder 2 while also engaging with the child member (child girder 3).

[0075] In this way, the mounting member 40 of the present invention can easily prevent the movement of the clamp member 30 relative to the main beam 2 and the movement of the clamp member 30 relative to the child member (child beam 3).

[0076] (h) The clamp member 30 is positioned opposite the cover member 20 at a predetermined distance and has a strip-shaped opposing wall 31 whose longitudinal direction F intersects the pair of main beams 2, two side walls 32 extending toward the cover member 20 from both ends of the opposing wall 31 in the short direction, and a lip portion 33 provided on each of the two side walls 32 and extending toward the opposing side wall 32 from the tip of the side wall 32, and the fastening portion 43 is sized to fit within the internal space S of the clamp member 30 surrounded by the opposing wall 31, the side walls 32, and the lip portion 33. The fastening portion 43 is formed to a size that prevents it from passing between the lip portions 33, and the connection point (connection portion 44) between the fastening portion 43 and the main body portion 41 is formed to a size that can be positioned between the lip portions 33. The mounting member 40 is configured such that the fastening portion 43 is positioned in the internal space S, and the connection point (connection portion 44) is positioned in the gap of the lip portions 33, and the fastening portion 43 of the mounting member 40 is fastened to the opposing wall 31 of the clamp member 30 with a fastening member, thereby fixing the clamp member 30 to the mounting member 40.

[0077] In this case, the fastening portion 43 of the mounting member 40 is formed to a size that prevents it from passing between the lip portions 33. Therefore, once the fastening portion 43 is placed in the internal space S of the clamp member 30, the fastening portion 43 is locked to the wall surface of the internal space S of the clamp member 30, and the mounting member 40 is temporarily fixed in place. By creating this state, the mounting member 40 of the present invention can improve the workability related to fastening with the clamp member 30.

[0078] Furthermore, in the present invention, of the screw 5 that fastens the clamp member 30 and the mounting member 40, the threaded portion (the part in which the crest and valley of the screw 5 is formed) is positioned in the internal space S of the clamp member 30, which is thinner than the head. This makes it difficult to cut the screw 5 with a cutting tool such as a grinder. As a result, the mounting member 40 of the present invention makes it more difficult to remove the clamp member 30 from the cable rack 1 and steal the cable K.

[0079] (i) The mounting member may be formed from a plate-shaped member.

[0080] In this way, the mounting member 40 of the present invention can increase the contact area with a cutting tool such as a grinder when cutting is attempted, compared to conventional linear hook members. Therefore, it is expected that the mounting member 40 of the present invention will be less likely to be cut when cutting, as the stress acting from the cutting tool will be distributed.

[0081] (j) The main beam 2 has a side surface 2a that extends in the longitudinal direction F, and the mounting member 40 is preferably mounted so that at least the main body portion 41 is formed in a plate shape and faces the side surface 2a of the main beam 2.

[0082] In this way, the mounting member 40 of the present invention can reduce the area that a cutting tool such as a grinder can access when cutting is attempted, and as a result, the cutting work can be made physically more difficult. Furthermore, the mounting member 40 of the present invention makes it easier to bring the main body 41 into contact with the side surface 2a of the main beam 2, and when contact is made in this way, it is expected that the stress acting from the cutting tool when cutting is attempted will be further dispersed, making it even more difficult to cut.

[0083] (k) The cable rack closure structure of the present invention is a cable rack closure structure in which a cable rack 1 having a cable accommodation area A closes an open portion 10 of the accommodation area A with a cover member 20, comprising a clamp member 30 that clamps the cover member 20 with respect to the cable rack 1, and a mounting member 40 that attaches the clamp member 30 to the cable rack 1, wherein the cable rack 1 is formed to extend in the longitudinal direction F, and comprises a pair of opposing main beams 2, the accommodation area A formed between the pair of main beams 2, and the open portion 10 The mounting member 40 has a child member (child girder 3) that is fixed to the main girder 2 in the longitudinal direction F at a position that is at the back (lower end) in the depth direction of the storage area A, and the mounting member 40 has a fastening portion 43 that is fastened to the clamp member 30 side, an engaging portion 42 that engages to the cable rack 1 side, and a main body portion 41 that connects the fastening portion 43 and the engaging portion 42, and when the engaging portion 42 is engaged to the cable rack 1 side, the movement of the mounting member 40 in the longitudinal direction F of the main girder 2 can be prevented by interference with the child member (child girder 3).

[0084] The cable rack closure structure of the present invention is configured such that, when the engaging portion 42 is engaged with the cable rack 1, the movement of the mounting member 40 in the longitudinal direction F of the main beam 2 is inhibited by interference between the mounting member 40 and the sub-member (sub-girder 3). In this way, the movement of the clamp member 30 in the longitudinal direction F relative to the cable rack 1 can be restricted, and therefore, the cable rack closure structure of the present invention can fix the clamp member 30 more firmly to the cable rack 1 compared to conventional cable rack closure structures.

[0085] Furthermore, the movement of the clamp member 30 in the longitudinal direction F can also be restricted by fixing the mounting member 40 to the cable rack 1 with screws or the like. However, the cable rack closure structure of the present invention can restrict the movement of the clamp member 30 in the longitudinal direction F by the mounting member 40 without using screws, thus allowing the clamp member 30 to be firmly fixed to the cable rack 1 with a simple configuration.

[0086] The above describes the effects and advantages of the mounting member 40 and cable rack closure structure according to the embodiment of the present invention. However, the mounting member 40 and cable rack closure structure of the present invention are not limited to the above-described embodiment and can be modified in various ways. That is, the above-described mounting member 40 and cable rack closure structure merely represent one embodiment of the present invention, and the configuration can be changed, omitted, or added as appropriate without departing from the spirit of the present invention. In other words, the mounting member 40 and cable rack closure structure can be made without some or all of the configurations described in (a) to (k) above, or with other configurations, or implemented with configurations different from those exemplified in the above embodiment, without departing from the spirit of the present invention.

[0087] For example, it is also possible to fasten the mounting member 40 and the clamp member 30 with the clamp member 30 shown in Figure 4 inverted vertically. Figure 5 is a perspective view showing a modified example of the mounting structure of the cover member of the present invention. The difference between the mounting structure according to this example and the above-described embodiment with reference to Figure 4 is that the mounting member 400 and the clamp member 30 are fastened with the clamp member 30 inverted vertically. The other components are the same as in the above-described embodiment, so their explanation is omitted by using the same reference numerals, and the explanation will focus on the differences.

[0088] In other words, as shown in Figure 5, the clamp member 30 is positioned on the cover member 20 and has an opposing wall 31 whose longitudinal direction F intersects with the pair of main beams 2, two side walls 32 extending away from the cover member 20 from both ends of the opposing wall 31 in the short direction, and a lip portion 33 provided on each of the two side walls 32 and extending from the tip of the side wall 32 toward the opposing side wall 32. The clamp member 30 is fixed to the mounting member 400 by fastening the fastening portion 430 of the mounting member 400 to the opposing wall 31 with a fastening member (screw 5) while the fastening portion 430 of the mounting member 400 is in contact with the opposing wall 31.

[0089] In this case, as shown in Figure 5, the length of the mounting member 400 (length in the height direction H of the main beam 2) is formed to be shorter than the length of the mounting member 40 in Figure 4. Figure 5 shows the case where only the dimensions of the main body portion 410 of the mounting member 400 (dimension in the height direction H) are changed, and the dimensions of the other connecting portion 440, engaging portion 420, and fastening portion 430 are the same as the dimensions of the connecting portion 44, engaging portion 42, and fastening portion 43 in Figure 4. Also in Figure 5, the length in the height direction H of the main body portion 410 is adjusted so that the upper surface of the fastening portion 430 of the mounting member 400 is on the same plane (so-called flush) as the upper surface of the cover member 20.

[0090] Here, when the inverted clamp member 30 is placed on the cover member 20, the opposing wall 31 of the clamp member 30 and the upper surface of the fastening portion 430 of the mounting member 400 are positioned opposite each other, and the opposing wall 31 and the fastening portion 430 are in contact or nearly in contact. In this state, the clamp member 30 and the mounting member 400 are fastened together by fastening the opposing wall 31 and the fastening portion 430 with a screw 5. According to this example, the same effect as that obtained by the configuration in (a) above can be obtained.

[0091] In this example, the width of the connecting portion 440 (the width of the longitudinal direction F of the main girder 2) can be changed as appropriate. For example, the width of the connecting portion 440 (the width of the longitudinal direction F of the main girder 2) may be increased so that it is the same size as the width of the main body portion 410 (the width of the longitudinal direction F of the main girder 2). Doing so reduces the risk of the mounting member 400 being cut by a cutting tool such as a grinder.

[0092] Furthermore, it is possible to change the shape of the mounting member 400 while maintaining the configuration in which the mounting member 400 and the clamp member 30 are fastened together with the clamp member 30 inverted. For example, as shown in Figures 6 and 7, it is possible to provide an extension portion 411a on the main body portion 411 of the mounting member 401 so as to fill the gap between the main body portion 411 of the mounting member 401 and the main beam 2.

[0093] In other words, the main body portion 411 of the mounting member 401 is positioned opposite the side surface 2a of the main girder 2, and it is preferable that the main body portion 411 has an extension portion 411a that extends toward the side surface 2a of the main girder 2 so as to fill the gap between the side surface 2a of the main girder 2 and the main body portion 411.

[0094] Specifically, the modified mounting member 401 shown in Figures 6 and 7 has a main body portion 411, an engaging portion 421, and a fastening portion 431. Here, the main body portion 411, the engaging portion 421, and the movement restricting portion 421a provided on the engaging portion 421 have the same configuration as the main body portion 41, the engaging portion 42, and the movement restricting portion 42a shown in Figure 2, so their explanation will be omitted, and the explanation will focus on the differences from the mounting member 400 shown in Figure 5.

[0095] In this case, extensions 411a are formed at both ends of the main body 411 in the longitudinal direction F of the main girder 2. The extensions 411a extend toward the side surface 2a of the opposing main girder 2, and their shape is processed to match the uneven shape of the side surface 2a so that they can fill the gap between the main body 411 and the side surface 2a of the main girder 2, as shown in Figures 6 and 7. The extensions 411a can be formed by bending the end of the main body 411 toward the side surface 2a of the main girder 2.

[0096] Furthermore, the fastening portion 431 of the mounting member 401 in this example is connected to the upper end of the main body portion 411 and is bent outwards from the upper end of the main body portion 411 in the width direction P (see Figure 7) toward the outside of the main beam 2. As shown in Figure 6, the width W7 of the fastening portion 431 (width F in the longitudinal direction of the main beam 2) is formed to be narrower than the width W6 of the main body portion 41 (W6 > W7). The fastening portion 431 is formed in the shape of a rectangular plate and has screw holes 431a for fastening with screws 5.

[0097] In this example, the mounting member 401 is formed so as to fill the gap between the main body 411 and the side surface 2a of the main girder 2. This makes it difficult for cutting tools used to cut the mounting member 401 or the cable K to enter the gap, thereby suppressing theft of the cable K. In Figures 6 and 7, the mounting member 411 is formed at both ends of the main girder 2 in the longitudinal direction F of the main body 411, making theft of the cable K more difficult. However, the configuration of the mounting member 411 is customizable. For example, the mounting member 411 is formed at only one end of the main body 411. Alternatively, the mounting member 411 is not formed at the end of the main body 411. In this case, for example, the mounting member 411 is formed near the center of the main body 411 in the longitudinal direction F. In this case, the mounting member 411 can be fixed to the main body 411 by welding or other means.

[0098] Furthermore, in the above-described embodiment, the fastening portion 43 of the mounting member 40 was explained as an example in which it is bent outwards from the upper end of the main body portion 41 (connecting portion 44) toward the outside of the pair of main girders 2. However, it is also possible to configure the fastening portion 43 to be bent in the opposite direction. That is, it is also possible to provide the fastening portion 43 of the mounting member 40 so as to extend inwards toward the pair of main girders 2 in the width direction P from the upper end of the connecting portion 44.

[0099] For example, the fastening portion 431 of the mounting member 401 shown in Figure 6 can be provided so as to extend inward from the upper end of the main body portion 411 in the width direction P (see Figure 7) towards the pair of main girders 2 (see Figure 8). In this case, the width of the fastening portion 432 in the longitudinal direction F (longitudinal direction F of the main girders 2) is formed to be the same size as the width of the main body portion 411 in the longitudinal direction F. The fastening portion 432 is formed in the shape of a rectangular plate and has screw holes 432a for fastening with screws 5. The fastening portion 432 can be formed by bending the upper end of the main body portion 411 inward towards the main girders 2.

[0100] Note that parts of the mounting member 402 shown in the modified example in Figure 8 and the mounting member 401 shown in the modified example in Figure 6 that have the same configuration are denoted by the same reference numerals, and their explanation is omitted. The configuration of the mounting member 402 in this example provides the same effects as the above-described embodiment and modified example. Furthermore, by forming the fastening portion 432 by bending it inward on both parent girders 2, the longitudinal length (length in the width direction P) of the clamp member 30 can be shortened, thus enabling miniaturization of the cable rack 1.

[0101] Furthermore, in the embodiments and modifications described above, it is also possible to provide an adhesive layer between the fastening portions 43, 430, 431, and 432 of the mounting members 40, 400, 401, and 402 and the opposing wall 31 of the clamp member 30, thereby bonding the fastening portions 43, 430, 431, and 432 to the opposing wall 31 with the adhesive layer. In this case, the fastening of the mounting members 40, 400, 401, and 402 to the clamp member 30 can be done together with the screws 5, or by using the adhesive layer instead of the screws 5. For example, if the mounting members 40, 400, 401, and 402 to the clamp member 30 is fixed together with the screws 5 using the adhesive layer, even if the fastening members (screws 5) are cut with a cutting tool such as a grinder, the mounting members 40, 400, 401, and 402 to the clamp member 30 will still be fixed by the adhesive layer, making it even more difficult to remove the clamp member 30 from the cable rack 1.

[0102] For example, adhesive tapes such as double-sided tape or adhesives can be used as an adhesive layer. When forming the adhesive layer with an adhesive, one possible method is to inject the adhesive through the screw holes 31a of the clamp member 30 or the screw holes 43a, 431a, and 432a of the mounting members 40, 400, 401, and 402 to form an adhesive layer between the opposing wall 31 and the fastening parts 43, 430, 431, and 432.

[0103] Furthermore, in the present invention, the member corresponding to the sub-girder 3 does not have to be girder-shaped, and can be appropriately changed as long as it is a member that does not move relative to the main girder 2 in the longitudinal direction F.

[0104] The above describes embodiments and modifications of the mounting member and cable rack closure structure according to the present invention. However, the present invention is not limited to those exemplified in the above embodiments and modifications, and it will be readily apparent to those skilled in the art that other embodiments may exist in the spirit and teachings thereof, without departing from the scope of the claims. [Industrial applicability]
