Description

Technical Field

[0001] The present disclosure relates to a multifunctional pole capable of mounting equipment. Background Art

[0002] Patent Document 1 discloses a modular outdoor lighting device. Equipment such as lighting is mounted on a single support column called a main pole. The main pole has a mounting groove, and each equipment is mounted through the mounting groove.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2021-22555

[0004] Consider a multifunctional pole that can be used to install equipment through the groove. If the groove of the pole installed in the urban area is exposed at the outer periphery, it is easy for fingers, goods, etc. to get caught when pedestrians touch or lean on it, which is unsafe.

[0005] As a countermeasure, it is possible to cover the exposed grooves on the outer periphery of the rod with a plate. However, this is not reasonable from the perspective of component cost and installation work. In addition, there is a high possibility that the fasteners of the mounting plate will protrude from the surface of the plate, which cannot solve the safety concerns. Summary of the invention

[0006] An object of the present disclosure is to provide a technology that ensures economic rationality and ensures safety in a multifunctional pole capable of mounting equipment through a groove portion.

[0007] The first aspect relates to a multifunctional pole capable of mounting equipment.

[0008] The multifunctional pole has multiple struts.

[0009] The plurality of pillars form opposing surfaces that face each other.

[0010] A groove is provided on a facing surface of at least a first support among the plurality of supports along a longitudinal direction of the first support.

[0011] The second viewpoint has the following features in addition to the first viewpoint.

[0012] The first support column is provided with a through hole along the length direction of the first support column.

[0013] The multifunctional pole also has nodes that connect the plurality of struts to each other.

[0014] The node portion includes a shell portion, a node inner cavity portion surrounded by the shell portion, and a shell hole provided in the shell portion.

[0015] The node and the first support are provided with communication holes for spatially connecting the hollow portion in the node and the through holes of each support.

[0016] According to the first viewpoint, the multifunctional rod has a plurality of pillars, and the plurality of pillars form an opposing surface. The opposing surface is different from the outer peripheral surface of the multifunctional rod as a whole, and is not exposed toward the outside of the multifunctional rod. Since the groove is provided on such an opposing surface, the groove and the joint are not present on the outer peripheral portion of the multifunctional rod. Therefore, even if there is no structure equivalent to the plate covering the groove, the above situation is unlikely to occur. That is, it can be said that the safety is high and there is economic rationality.

[0017] In addition, since there are gaps between the plurality of pillars that are components of the multifunctional pole, pedestrians can see the opposite side of the multifunctional pole through the gaps. That is, compared with the case of providing a single thick pole, the blind spot is reduced. This is preferable from the perspective of safety. In addition, the effect of reducing the sense of oppression and increasing the sense of openness can be expected.

[0018] According to the second viewpoint, in the case where the device installed on the multifunctional pole has a cable, the wiring of the cable can be stored inside the multifunctional pole. According to the second viewpoint, the multifunctional pole has a node. In addition, the pillar has a through hole. The node has an outer shell, a hollow portion in the node, and an outer shell hole. The hollow portion in the node is connected to the external space through the outer shell hole. A communication hole is provided in such a way that the through hole on the pillar side is connected to the hollow portion in the node on the node side. That is, a communication path connecting the outer shell hole, the hollow portion in the node, the communication hole, and the through hole is formed from the external space. The cable of the device can pass through the communication path. As a result, the cable is not easily visible from the outside, and the appearance of the multifunctional pole is improved.

[0035] Embodiments of the present disclosure will be described with reference to the drawings.

[0036] 1. The main components of the multifunctional rod

[0037] Figure 1 : is a three-dimensional diagram showing the whole of the multifunctional pole 1. The multifunctional pole 1 is mainly installed outdoors in urban areas and the like in a direction perpendicular to the ground. Various devices 50 such as lighting equipment, cameras, communication antennas, speakers, electronic signs, and logos can be installed on the multifunctional pole 1. Specific installation examples of the devices 50 will be described later. Here, for the sake of explanation, an XYZ coordinate system is determined as the overall coordinate system. The Z axis is parallel to the height direction of the multifunctional pole 1. A plane orthogonal to the Z axis direction is defined as an XY plane. The XY plane is defined by the X axis and the Y axis, and is depicted in the accompanying drawings as the X axis and the Y axis being orthogonal to each other.

[0038] The electrically controlled device among the devices 50 installed in the multifunctional pole 1 can be controlled by a device built into the multifunctional pole 1. When many multifunctional poles 1 are installed in a certain area, the control can be performed through communication. For example, in a base such as a management center, a plurality of multifunctional poles 1 installed in the entire area can be managed uniformly.

[0039] The multifunctional rod 1 has a plurality of pillars 10. Typically, the pillars 10 are steel parts formed by hot extrusion or the like. In addition, the surface may be subjected to a high durability treatment by galvanizing or the like. For example, the plurality of pillars 10 are arranged parallel to each other. The extending direction of each pillar 10 is, for example, a vertical direction.

[0040] The multifunctional rod 1 further includes a base 40. The support column 10 is connected to the base 40. Typically, the base 40 is made of metal such as steel. Figure 1 In the illustrated example, the support column 10 and the base portion 40 are joined by welding.

[0041] The multifunctional lever 1 further comprises a node 30. Figure 1 In the figure, the node 30 embedded between the pillars 10 is depicted to connect the plurality of pillars 10. The detailed structure and effect of the node 30 will be described later. The node 30 is also similar to the base 40, and is typically made of steel and joined to the pillar 10 by welding.

[0042] 1-1. Cross-section of the multifunctional rod

[0043] Figure 2 This is a cross-sectional view of a multifunctional rod 1 having four pillars 10 cut in an XY plane. The four pillars 10 form opposing surfaces 11 that are opposed to each other. Here, it is preferred that the opposing surfaces 11 that are opposed to each other are separated from each other. Each pillar 10 has two opposing surfaces 11. The two opposing surfaces 11 are substantially orthogonal. For example, in each pillar 10, the opposing surface 11 is formed in a planar shape, and the outer peripheral surface other than the opposing surface 11 is formed in a curved surface shape.

[0044] The facing surface 11 of each support 10 is provided with a groove 12. In other words, each support 10 has a groove 12 on the facing surface 11. The groove 12 of each support 10 extends along the longitudinal direction of each support 10. Figure 2 In the example shown, the groove 12 includes a narrow portion 12a and a wide portion 12b. The narrow portion 12a exists on the surface of the support 10 (on the facing surface 11). The wide portion 12b exists on the inner side of the support 10 than the narrow portion 12a. The width of the narrow portion 12a is narrower than the width of the wide portion 12b. Typically, when the support 10 is cut in the XY plane, the groove 12 presents a T-shape.

[0045] exist Figure 3A In addition to the pillar 10 having Figure 2 In addition to the groove 12 of the same shape, there are also through holes 13 and cutouts 14. The through holes 13 are provided inside the pillar 10. On the other hand, the cutouts 14 are provided on the surface of the pillar 10. The groove 12, the through holes 13 and the cutouts 14 of each pillar 10 extend along the length direction of each pillar 10. Figure 3B Is has Figure 3AThe through hole 13 and the cutout 14 contribute to the lightness of the multifunctional pole 1 and play an effect in the wiring of the device 50 when the device 50 has a cable (details will be described later). The cable mentioned here is, for example, a power cable, a communication cable, etc.

[0046] 1-2. Fixing parts

[0047] A bracket 60 for mounting the device 50 may be mounted on the support column 10. The bracket 60 is fixed to the support column 10 by the fixing member 20 and the joint 70. The mechanism will be described below.

[0048] Figure 4 1 is a diagram showing the positional relationship among the pillar 10, the fixing member 20, the bracket 60 and the joint 70. The shape of the fixing member 20 corresponds to the shape of the groove 12. Specifically, the fixing member 20 includes a first portion 20a and a second portion 20b. The width of the first portion 20a is smaller than the width of the narrow portion 12a of the groove 12. In addition, the width of the second portion 20b is larger than the width of the narrow portion 12a of the groove 12, and smaller than the width of the wide portion 12b of the groove 12. That is, the fixing member 20 is a shape obtained by reducing the groove 12 by one circle, and is in a shape that is accommodated inside the groove 12. For example, the fixing member 20 is accommodated inside the groove 12 by sliding from the end of the groove 12. As the material of the fixing member 20 and the bracket 60, steel can be exemplified.

[0049] Here, the STU coordinate system is determined as a new coordinate system for the fixing component 20. The previously defined XYZ coordinate system is an overall coordinate system, whereas the STU coordinate system is an element-fixed coordinate system for the fixing component 20. The ST plane is a plane parallel to the XY plane when the fixing component 20 is housed inside the groove 12. The U-axis direction is a direction orthogonal to the ST plane. The ST plane is defined by the S-axis and the T-axis, and in the accompanying drawings, the S-axis and the T-axis are depicted as being orthogonal to each other. The "width" of the above-mentioned first portion 20a and the second portion 20b refers to the dimension of the fixing component 20 in the T direction.

[0050] exist Figure 4In the example shown, the fastener 70 is a bolt 70A, a tap hole corresponding to the bolt 70A is provided in the fixing member 20, and a hole corresponding to the diameter of the bolt 70A is provided in the bracket 60. When the bolt 70A is fitted into the fixing member 20 and tightened, the bracket 60 is fixed due to the interference between the convex portion 12c (pillar 10 side) adjacent to the narrow width portion 12a and the second portion 20b (fixing member 20 side). The device 50 is connected to the bracket 60 by a method such as mechanical joining based on bolts and nuts, welding joining, etc. In addition, the device 50 can also be directly fixed to the pillar 10 without passing through the bracket 60. For example, if the device 50 is a plate-shaped mark provided with a hole corresponding to the diameter of the bolt 70A, the device 50 can be directly fixed to the pillar 10 instead of the bracket 60 in the figure.

[0051] 2. Topics and effects on topics

[0052] In the prior art (e.g., Patent Document 1), the main structure of the pole is composed of one pillar called a main pole, and the mounting groove corresponding to the groove portion 12 of the present invention is a structure that appears on the outer periphery of the main pole. For example, imagine a situation where pedestrians touch or lean on the pole described in Patent Document 1 when the pole is installed in an urban area. In this case, if the mounting groove and bolts are located on the outside, fingers, clothes, and belongings can easily get caught, and it cannot be said that the safety is high. However, Patent Document 1 also describes a structure called a module plate that covers the mounting groove. However, from the perspective of the cost of the components and the time required for installation, it is not reasonable to use such a plate to cover the entire surface of the pole. In addition, there is a concern that the heads of the bolts of the mounting plate will protrude from the surface of the plate.

[0053] On the other hand, the multifunctional rod 1 of the present invention includes a plurality of pillars 10, and these plurality of pillars 10 form an opposing surface 11. The opposing surface 11 is different from the outer peripheral surface of the multifunctional rod 1 as a whole, and is not exposed to the outside of the multifunctional rod 1. Since the groove 12 is provided on such an opposing surface 11, the groove 12 and the joint 70 are not present on the outer peripheral portion of the multifunctional rod 1. Therefore, even if there is no component equivalent to the module plate covering the groove 12, the above situation is not likely to occur. That is, it can be said that the multifunctional rod 1 of the present invention is highly safe and economically reasonable.

[0054] In addition, since there are gaps between the plurality of pillars 10 that are components of the multifunctional pole 1, pedestrians can see the opposite side of the multifunctional pole 1 through the gaps. That is, compared with the case of providing a single thick pole, the blind spot is reduced. This is preferable from the viewpoint of safety. In addition, the effect of reducing the sense of oppression and increasing the sense of openness can be expected.

[0055] As described above, each support post 10 may be provided with a through hole 13. When the device 50 has a power cable or a communication cable, the cable can be passed through the through hole 13. Thus, the cable is not easily visible from the outside, and the appearance of the multifunctional pole 1 is improved.

[0056] Furthermore, by making the support column 10, the node portion 30, and the base portion 40 into a fixed structure, when the device 50 has a power cable or a communication cable, the cables can be wired more appropriately.

[0057] As described above, various devices such as lighting equipment, cameras, communication antennas, speakers, electronic signs, and logos can be installed on the multifunctional pole 1. If the wiring of the cable 51 of the device 50 installed on the upper part of the support 10 is exposed, the appearance becomes complicated and is not preferred. However, if it is a structure described later, the cable 51 can pass through the inside of the multifunctional pole 1, which is preferred in terms of appearance.

[0058] Figure 5A 30. The node 30 is formed by welding steel plates, and its outer shape is roughly a rectangular parallelepiped. In addition, its structure can be divided into an outer shell 31 and an inner cavity 32. An outer shell hole 33 is provided on the surface of the outer shell 31, and the inner cavity 32 is connected to the external space through the outer shell hole 33. Figure 5B The positional relationship when the node 30 and the support column 10 are joined is shown. The node 30 connects the plurality of support columns 10 .

[0059] Figure 6 It is a three-dimensional diagram showing the joint of the node 30 and the pillar 10. Here, the pillar 10 has the above-mentioned through hole 13 and the cutout 14. In addition, for the sake of explanation, a part of the pillar 10 and the node 30 is omitted for illustration. In the portion shown by the dotted line in the figure, a communication hole 81 is provided in a manner that the through hole 13 (pillar 10 side) is connected to the hollow portion 32 in the node (node ​​30 side). In addition, as mentioned above, the hollow portion 32 in the node is connected to the external space through the outer shell hole 33. Therefore, a communication path 80 is formed that reaches the through hole 13 from the external space via the outer shell hole 33, the hollow portion 32 in the node and the communication hole 81.

[0060] Figure 7 4 is a three-dimensional view of the base 40. Here, the base 40 is a box-shaped structure formed by welding steel plates, and is provided with a door 41. The internal space of the base 40 can be accessed through the door 41. The base 40 is connected to the support 10 (for example, by welding) in a form in which the end of the support 10 penetrates the upper surface of the base 40 and appears on the inner side. Therefore, the through hole 13 is connected to the internal space of the base 40. That is, this means that the internal space of the base 40 is connected to the communication path 80.

[0061] With the above structure, the cable 51 extending from the device 50 installed on the top of the support 10 can pass through the inside of the multi-function pole 1 through the communication path 80 and reach the internal space of the base 40. Therefore, since most of the cable 51 is not visible from the outside, it is preferred in terms of appearance. In addition, if various devices (power supply device, communication device, etc.) are stored in the internal space of the base 40, various operations can be performed through the door 41, and the maintainability is also improved.

[0062] Furthermore, in this structure, the cable 51 is also exposed to the outside before entering the housing hole 33 of the node 30 from the device 50. Figure 6 As shown, if the cable 51 is arranged along the cutout 14, the cable 51 is hidden by the cutout 14 and cannot be seen from the outside. This further improves the aesthetic appearance.

[0063] In the embodiments described or illustrated so far, the groove 12 is provided on the facing surface 11 of each support 10. However, as long as the groove 12 is provided on the facing surface 11 of at least one support 10, the same effect can be obtained.

[0064] 4. Other configuration examples

[0065] 4-1. Number of pillars constituting the multifunctional pole

[0066] In the structure of the multifunctional rod 1 shown so far, the support 10 has grooves 12 on two sides, and the number of the grooves 12 is four. However, the number of the support 10 is not limited to a specific number as long as it is a plurality. Figure 8 As shown, the structure is composed of four pillars 10 and two pillars 10A, in which a pillar 10A having grooves 12 on three surfaces is combined.

[0067] 4-2. Shape of the groove and fixing member

[0068] Fig. 9 1 shows another configuration example of the groove 12. Here, the groove 12 has an opening 12A that partially does not have the narrow width portion 12a. In this case, the fixing member 20 can enter the inside of the groove 12 from the opening 12A without sliding from the end of the groove 12. By providing such an opening 12A, the efficiency of the assembly and disassembly work and the replacement work of the bracket 60 is improved.

[0069] In addition, the fixing member 20 can also be rotated and accommodated in the groove portion 12 by satisfying certain dimensional conditions. Fig. 10AIn the example, the height 20c (dimension in the U-axis direction) of the fixing member 20 is smaller than the narrow width portion 12a of the groove 12. If the width of the second portion 20b of the fixing member 20 (dimension in the T-axis direction) is smaller than the wide width portion of the groove 12 by a certain amount or more, the fixing member 20 can rotate on the UT plane in the groove 12. Therefore, the fixing member 20 is inserted into the groove 12 in a manner parallel to the T-axis direction and the Z-axis direction, and the fixing member 20 can be accommodated in the groove 12 by being rotated in the groove 12. In this case, since the fixing member 20 can be placed inside the groove 12 without sliding from the end of the groove 12, the efficiency of the installation and replacement operations of the bracket 60 is improved.

[0070] Furthermore, even if the size of the fixing member 20 is large and the fixing member 20 cannot rotate in the groove 12, the fixing member 20 can be rotated by cutting off a part of the fixing member 20 into an arc shape or an obtuse angle shape. Fig. 10B In the figure, when the fixing member 20 is rotated in the direction of the arrow, the corners 20d and 20e are likely to interfere with the outer edge of the groove 12. In this figure, the fixing member 20 is prevented from interfering with the outer edge of the groove 12 by cutting off the corners 20d and 20e to form an arc shape. As a result, the height 20c of the fixing member 20 can be made larger than that of the previous section. As a result, the contact area between the fixing member 20 and the support 10 becomes larger, and a larger load can be withstood.

[0071] 4-3. Example of bracket installation configuration

[0072] The bracket 60 may be mounted only in one groove portion 12, or may be mounted across the groove portions 12 of a plurality of pillars 10. In addition, one bracket 60 may be joined to the same groove portion 12 at a plurality of locations.

[0073] Fig.11 , 12 13 shows an example of the mounting structure of the bracket 60. Fig.11 In the example shown, the bracket 60 straddles two pillars 10 and engages with one groove 12 at two locations. Fig.12 In the example shown, two brackets 60 are mounted on one support column 10. The two brackets 60 are fastened together by bolts. Fig.13 The bracket 60 shown in the figure is connected to the set of opposing grooves 12. By forming the above-mentioned structure, even the device 50 having a weight that cannot be fully supported by only a few joints can be supported.
