DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The restricting member and wiring duct system of the present disclosure will be described with reference to the drawings. However, the following embodiments are merely a part of various embodiments of the present disclosure. The following embodiments can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, each figure described in the following embodiments is a schematic diagram, and the size and thickness ratio of each component in the figure do not necessarily reflect the actual dimensional ratio. Furthermore, the following embodiments (including modified examples) may be realized by appropriately combining them.

[0011] (Embodiment) (overview) First, an overview of the restricting member 8 according to this embodiment, the adapter 5 to which the restricting member 8 is applied, and the wiring duct system 100 will be described.

[0012] FIG. 1 is a perspective view showing the restricting member 8, the adapter 5, and a part of the wiring duct system 100, specifically showing a state in which the restricting member 8 is attached to the adapter 5 in the wiring duct system 100. FIG. 2 is a perspective view showing the restricting member 8, the adapter 5, and a part of the wiring duct system 100, specifically showing a state in which the restricting member 8 is separated from the adapter 5 in the wiring duct system 100. In the following, as shown in FIG. 1 and FIG. 2, the longitudinal direction in a state in which the wiring duct 3 is normally installed on an object to which it is to be attached (for example, a fixture) is defined as the "left-right direction", the width direction which is a direction perpendicular to the longitudinal direction is defined as the "up-down direction", and the depth direction which is perpendicular to both the longitudinal direction and the width direction is defined as the "front-rear direction". However, the terms up-down, left-right, and front-rear are defined for the convenience of explanation and are not intended to limit the direction of use.

[0013] Figures 10 to 13 are diagrams showing application examples of the wiring duct system 100, with Figure 10 being a perspective view, Figure 11 being a front view, Figure 12 being a right side view, and Figure 13 being a plan view. In Figures 10 to 13 as well, the longitudinal direction in a mode in which the wiring duct 3 is normally installed on a fixture or the like is defined as the "left-right direction", the width direction as the "up-down direction", and the depth direction as the "front-rear direction", but the terms up-down, left-right, and front-rear are defined for the sake of convenience of explanation and are not intended to limit the direction of use.

[0014] The restricting member 8 according to the present embodiment is configured to restrict removal of the adapter 5 from the wiring duct system 100, as shown in FIG. 1. Here, the restricting member 8 is configured to be attached externally to the adapter 5 in a state connected to the wiring duct system 100. The restricting member 8 includes a flat plate-shaped portion 80 and a switching portion 82. The flat plate-shaped portion 80 includes an end surface portion 81 that contacts at least a part of the adapter 5. The switching portion 82 is switched between a locked state and an unlocked state by a switching key K1. The restricting member 8 is attached to the wiring duct 3 in such a manner that the end surface portion 81 contacts at least a part of the adapter when the switching portion 82 is in the locked state, and restricts removal of the adapter 5. The plate thickness direction of the flat plate-shaped portion 80 is a direction perpendicular to the mounting surface 502 of the adapter 5. The end surface portion 81 is formed along the plate thickness direction. The plate thickness direction coincides with the depth direction, that is, the front-rear direction, as shown in FIG. 1 and FIG. 2.

[0015] The wiring duct system 100 has a wiring duct 3 to which an adapter 5 to which a connector 95 is connected can be detachably attached. Here, the wiring duct 3 has a duct rail 31 (see Figs. 1, 2, 5, 6, etc.) and a conductive bar 32 (see Figs. 1, 2, 5 to 8, etc.). Here, as an example, the conductive bar 32 can be electrically connected to the adapter 5 at any position in a continuous mounting area in the longitudinal direction of the duct rail 31. In other words, the adapter 5 is attached to any position in a continuous mounting area in the longitudinal direction of the wiring duct 3. A connector 95 (see Fig. 18) that receives direct current (DC) power can be connected to the adapter 5. The wiring duct system 100 supplies direct current (DC) power to the connector 95 via the adapter 5. The conductive bar 32 is stored in the duct rail 31.

[0016] The attachment region is a region provided on the surface or inside of the duct rail 31. The wiring duct 3 of this embodiment includes a recessed storage section 3110 (see Figs. 1 and 2) formed along the longitudinal direction of the duct rail 31. More specifically, the recessed storage section 3110 is formed across both ends in the longitudinal direction of the duct rail 31. The attachment region coincides with the region where the recessed storage section 3110 is provided.

[0017] The connector 95 is a connector for the electric device 94 (or for a cable connected to the electric device 94). By connecting the connector 95 to the adapter 5, it is possible to supply power from the wiring duct 3 to the electric device 94. This makes it easier to improve the management of wiring compared to a case where power is supplied to the electric device 94 from a power outlet or a power tap that distributes power from a power outlet.

[0018] There is no particular limitation on the type of the electrical device 94. Examples of the electrical device 94 include computer terminals (personal computers, smartphones, tablet terminals, etc.), computer terminal accessories (monitors, speakers, microphones, etc.), lighting equipment (desk lights, etc.), network cameras, sensors (temperature sensors, humidity sensors, illuminance sensors, etc.), game consoles, and air conditioners (desk fans, etc.).

[0019] The wiring duct system 100 is used, for example, by being fixed to a fixture. A fixture is a general term for furniture, fixtures, and other equipment used in a residential or non-residential building. Examples of fixtures include desks, tables, and workbenches used as platforms for placing items. Other examples of fixtures include shelves, boxes, dressers, beds, whiteboards, screens, partitions, and benches.

[0020] In Figs. 10 to 17, the wiring duct system 100 will be described as an example in which it is fixed to a desk 7 as a piece of furniture. As shown in Fig. 10, the desk 7 has a top plate 71 having a rectangular shape in a plan view, two legs 72, and two support bases 73. In the following, with respect to Fig. 10, the direction along the long side of the top plate 71 may be defined as the left-right direction, the direction along the short side of the top plate 71 may be defined as the front-rear direction, and the direction along the normal line of the top plate 71 may be defined as the up-down direction. However, these definitions are not intended to limit the direction in which the wiring duct system 100 is used. Also, the arrows representing the front-rear, left-right, and up-down directions in Figs. 1, 2, 4, 6 to 17, etc. are merely shown for the purpose of explanation and do not have any substance.

[0021] As described above, the wiring duct system 100 is installed on a piece of furniture such as a desk 7. That is, from the viewpoint of convenience, the adapter 5 can be installed in a position that is relatively easy to reach for a person, for example, a user who uses power supply from the wiring duct 3. In that case, there is a concern that the adapter 5 may be taken out of the wiring duct 3 by a person (such as a user) without permission.

[0022] In contrast, the restricting member 8 of this embodiment, as shown in Fig. 1, includes a flat plate-shaped portion 80 including an end surface portion 81 that covers at least a portion of the adapter 5, and a switching portion 82 that is switched between a locked state and an unlocked state by a switching key K1. When the switching portion 82 is in the locked state, the restricting member 8 is attached to the wiring duct 3 in such a manner that the end surface portion 81 covers at least a portion of the adapter 5, thereby restricting removal of the adapter 5. Note that, as an example, "at least a portion" referred to here is assumed to be the operating portion 52 of the adapter 5 (see Fig. 1, etc.). The operating portion 52 will be described in detail later.

[0023] According to this configuration, unless the switching unit 82 is unlocked by the switching key K1, the restricting member 8 restricts removal of the adapter 5. As a result, the adapter 5 is less likely to be removed from the wiring duct 3. Furthermore, the restricting member 8 of this embodiment has a thickness direction perpendicular to the mounting surface 502 of the adapter 5 and the end surface portion 81 is formed along the thickness direction, which can improve the strength of the restricting member 8.

[0024] Therefore, according to the restricting member 8 of the present embodiment, it is possible to realize a restricting member 8 and a wiring duct system 100 that make it difficult for the adapter 5 to be removed from the wiring duct 3 and have high strength.

[0025] (detail) (1) Wiring duct system Next, the wiring duct system 100 to which the restricting member 8 is applied and each of the configurations that can be used in the wiring duct system 100 will be described in more detail.

[0026] The wiring duct system 100 includes an adapter 5, a wiring duct 3, and a restricting member 8. The wiring duct system 100 supplies power to a connector 95 via the adapter 5. In this embodiment, the power supplied to the connector 95 in the wiring duct system 100 is direct current (DC), and in the following description of the embodiment, unless otherwise specified, the case where the power supplied is direct current (DC) will be described. However, as described in a modified example below, the power received by the wiring duct system 100 and supplied to the connector 95 may be alternating current (AC).

[0027] As shown in FIG. 10, the wiring duct system 100 includes a duct fixing device F1, two wiring ducts 3 (only one is shown in FIG. 10), two feed-ins 4 (only one is shown in FIG. 10) (feed-in caps; see FIG. 14), and two end caps E1 (only one is shown in FIG. 14). The duct fixing device F1 has two first fixing parts 1 and two second fixing parts 2. The two first fixing parts 1 correspond one-to-one to the two wiring ducts 3. Each first fixing part 1 holds a corresponding wiring duct 3. That is, each wiring duct 3 is fixed to the corresponding first fixing part 1. The two second fixing parts 2 are fixed to a piece of furniture (a desk 7).

[0028] The components used in the wiring duct system 100 include one or more adapters 5 (see FIGS. 1 and 2), three partitions 6, and a desk 7.

[0029] (2) desk As shown in Fig. 10, the desk 7 has a top board 71 having a rectangular shape in a plan view, two legs 72, and two support bases 73. One of the two legs 72 protrudes downward from near the right end of the top board 71, and the other protrudes downward from near the left end of the top board 71. The two support bases 73 correspond one-to-one to the two legs 72. Each support base 73 is connected to the lower end of the corresponding leg 72 and supports the leg 72.

[0030] (3) First fixed part As shown in Fig. 13, the two first fixing parts 1 are aligned front to back and fitted to each other. As shown in Fig. 14, each of the two first fixing parts 1 includes a duct housing part 11 and two connecting protrusions 12. The duct housing part 11 and the two connecting protrusions 12 are integrally formed.

[0031] The duct storage section 11 is shaped like a rectangular parallelepiped. The duct storage section 11 has a length in the left-right direction. One of the two connecting protrusions 12 protrudes from the right end of the duct storage section 11, and the other protrudes from the left end of the duct storage section 11. The duct storage section 11 stores the wiring duct 3 (and the duct rail 31 of the wiring duct 3). The duct storage section 11 also stores the feed-in 4. Each of the two connecting protrusions 12 is configured to connect the first fixing part 1 to the second fixing part 2.

[0032] Each first fixed portion 1 has a storage groove 130 and two wire passage grooves 140. The storage groove 130 stores the wiring duct 3 and the feed-in 4. A wire W1 (see FIGS. 16A and 16B) electrically connected to the wiring duct 3 is passed through the wire passage groove 140.

[0033] The storage groove 130 is provided in the duct storage portion 11. The storage groove 130 is formed along the longitudinal direction (left-right direction) of the duct storage portion 11. In the front first fixing portion 1 of the two first fixing portions 1, the storage groove 130 opens at the front surface of the duct storage portion 11, and in the rear first fixing portion 1, the storage groove 130 opens at the rear surface of the duct storage portion 11.

[0034] The two wire passing grooves 140 correspond one-to-one to the two connecting protrusions 12. Each wire passing groove 140 is provided across the corresponding connecting protrusion 12 and the duct storage section 11. That is, the wire passing grooves 140 are provided at the right end and the left end of the first fixing section 1, respectively. Each wire passing groove 140 is formed along the longitudinal direction (left-right direction) of the duct storage section 11. In the front first fixing section 1 of the two first fixing sections 1, each wire passing groove 140 opens at the rear surface of the duct storage section 11, and in the rear first fixing section 1, each wire passing groove 140 opens at the front surface of the duct storage section 11.

[0035] When the two first fixing parts 1 are joined together, the wire passing grooves 140 at the right ends of the two first fixing parts 1 are joined together to form one space (see FIG. 16A), and the wire passing grooves 140 at the left ends of the two first fixing parts 1 are joined together to form another space. Each wire passing groove 140 is connected to the storage groove 130. The wiring W1 passed through the wire passing groove 140 is electrically connected to the terminal portion 432 (see FIGS. 16A and 16B) of the feed-in 4 stored in the storage groove 130, and is electrically connected to the conductive bar 32 of the wiring duct 3 (see FIGS. 15 and 16A) via the terminal portion 432.

[0036] Each of the two first fixing parts 1 has four recesses 150 (only two are shown in FIG. 14) as a part of the partition fixing structure S1. The four recesses 150 are provided in the duct storage section 11. When the two first fixing parts 1 are joined together, the four recesses 150 of each of the two first fixing parts 1 are joined together to form four gaps between the two first fixing parts 1. Each of these four gaps corresponds to a partition fixing structure S1. More specifically, each partition fixing structure S1 is a through hole that penetrates the structure in which the two first fixing parts 1 are joined together in the vertical direction. The four partition fixing structures S1 are lined up in the horizontal direction. Each partition 6 is fixed to the two first fixing parts 1 by inserting an engagement protrusion protruding from its lower part into the corresponding partition fixing structure S1.

[0037] (4)Second fixed part 14, each of the two second fixing parts 2 includes a cross section 21, a support section 22, and a clamp mechanism 23. The cross section 21 and the support section 22 are integrally formed. The two second fixing parts 2 are fixing members for fixing the duct rail 31 to a piece of furniture (a desk 7 in this example). More specifically, the two second fixing parts 2 are used together with the two first fixing parts 1 to fix the duct rail 31 to the desk 7.

[0038] The cross section 21 has a rectangular cylindrical shape. The axial direction of the cross section 21 is aligned with the left-right direction.

[0039] The two second fixing parts 2 correspond one-to-one to the two connecting protrusions 12 of each of the two first fixing parts 1. The corresponding connecting protrusions 12 of each of the two first fixing parts 1 are inserted into the horizontal part 21 of each second fixing part 2. Furthermore, the two first fixing parts 1 are screwed to the two second fixing parts 2, respectively. As a result, the two first fixing parts 1 are connected to the two second fixing parts 2. That is, the two first fixing parts 1 are connected to the two second fixing parts 2 so as to bridge between the two second fixing parts 2. In addition, each of the two first fixing parts 1 can be separated from the two second fixing parts 2. That is, by removing the screws connecting the two first fixing parts 1 and the two second fixing parts 2 and pulling out each connecting protrusion 12 from the horizontal part 21, each of the two first fixing parts 1 can be separated from the two second fixing parts 2.

[0040] The shape of the support part 22 is cylindrical. The axial direction of the support part 22 is along the up-down direction. The horizontal part 21 protrudes in the left-right direction from the upper end of the support part 22. The internal space of the horizontal part 21 is connected to the internal space of the support part 22 to form one internal space SP1 (see FIG. 14). A wire W1 (see FIG. 16A) is passed through the internal space SP1. That is, the second fixing part 2 has an internal space SP1 through which the wire W1 electrically connected to the conductive bar 32 (see FIG. 15) is passed.

[0041] The support post 22 has a wire hole 220. The wire hole 220 is provided on a side surface of the support post 22. The wire W1 is drawn from the internal space SP1 through the wire hole 220 to the outside.

[0042] The clamp mechanism 23 is fixed to the desk 7 by clamping the desk 7. More specifically, one of the two second fixing parts 2 clamps the left end of the top board 71 of the desk 7, and the other clamps the right end of the top board 71. In this way, the wiring duct system 100 is fixed to the desk 7.

[0043] The clamp mechanism 23 has a movable part 231, a base 232, and a movable member operating part 233 (see FIGS. 12 and 14).

[0044] The base 232 is formed integrally with the support column 22. The base 232 protrudes from the lower end of the support column 22 in the left-right direction.

[0045] The movable part 231 is disposed on a base 232. A part of the movable part 231 is disposed inside the wire passage hole 220 of the support part 22.

[0046] The movable member operation unit 233 receives an operation for vertically moving the movable unit 231. The movable member operation unit 233 is a lever, and when an operator turns the movable member operation unit 233, the movable unit 231 moves vertically.

[0047] Hereinafter, a procedure for fixing the wiring duct system 100 to the desk 7 using the clamp mechanisms 23 will be described. As shown in FIG. 11, the left end (or right end) of the tabletop 71 of the desk 7 is inserted into the wire-passing hole 220. As a result, the left end (or right end) of the tabletop 71 is disposed between the support 22 and the movable part 231. The worker turns the movable member operating part 233 to move the movable part 231 upward. As a result, the left end (or right end) of the tabletop 71 is sandwiched between the support 22 and the movable part 231. The left and right ends of the tabletop 71 are sandwiched using the clamp mechanisms 23 of each of the two second fixing parts 2, thereby fixing the wiring duct system 100 to the desk 7.

[0048] In addition, the support portion 22 ensures a gap G1 (see FIG. 11) between the two first fixed portions 1 of the wiring duct system 100 and the top plate 71 of the desk 7. That is, the gap G1 is ensured between the two duct rails 31 fixed to the two first fixed portions 1 and the top plate 71. In other words, the second fixed portion 2 includes the support portion 22 that supports the two duct rails 31 with a gap G1 between the two duct rails 31 and the desk 7. By passing through the gap G1, it is possible to pass documents and other objects between the front and rear of the desk 7. In addition, an opening may be provided in the top plate 71 of the desk 7 at a portion below the first fixed portion 1. The opening is configured to pull out wiring that supplies AC power from under the top plate 71. A user can insert his or her hand into the gap G1 and pull out the wiring through the opening.

[0049] (5) Wiring duct The wiring duct 3 has a conductive bar 32 and a duct rail 31 including a concave storage section 3110 in which the conductive bar 32 is stored. The concave storage section 3110 may be simply referred to as a "storage section 3110" below. In this embodiment, the wiring duct system 100 includes two wiring ducts 3 as described above, and each wiring duct 3 has a duct rail 31 and two conductive bars 32 as shown in Figs. 14 and 15. The duct rail 31 includes a first rail 311 and two second rails 312. The wiring duct 3 shown in Figs. 1 and 2 may correspond to either one of the two wiring ducts 3 shown in Fig. 13. Note that the first fixing portion 1 is omitted from Figs. 1 and 2.

[0050] The two wiring ducts 3 correspond one-to-one to the two first fixing parts 1. Each wiring duct 3 is stored in the storage groove 130 of the corresponding first fixing part 1. Therefore, one of the two wiring ducts 3 is disposed in front of the partition 6, and the other is disposed behind the partition 6.

[0051] In addition, the two wiring ducts 3 are positioned opposite each other in a specified direction (front-to-back direction) along the horizontal plane with the multiple wiring ducts 3 fixed to the first fixing part 1 and the second fixing part 2 fixed to the desk 7.

[0052] The first rail 311 has a rectangular cylindrical shape. The first rail 311 is made of, for example, metal. The axial direction (longitudinal direction) of the first rail 311 is along the left-right direction. The first rail 311 includes a storage section 3110. The storage section 3110 is formed along the longitudinal direction (left-right direction) of the duct rail 31. More specifically, the storage section 3110 is formed across both ends of the duct rail 31 in the longitudinal direction. Two conductive bars 32 are stored in the storage section 3110.

[0053] The storage section 3110 opens along a direction perpendicular to the surface of the partition 6. In other words, the storage section 3110 opens on a plane along the surface of the partition 6.

[0054] For example, as shown in FIG. 9, the first rail 311 further includes two fitting portions 3111 and two mounting grooves 3112.

[0055] Each of the two fitting portions 3111 is a groove. The two fitting portions 3111 are provided on the inner surface of the storage portion 3110. The two fitting portions 3111 are formed along the longitudinal direction (left-right direction) of the duct rail 31. More specifically, the two fitting portions 3111 are formed across both ends of the duct rail 31 in the longitudinal direction. The two fitting portions 3111 are fitted into the adapter 5. This allows the adapter 5 to be attached to the wiring duct 3. That is, the duct rail 31 includes an adapter attachment portion (in other words, two fitting portions 3111) for attaching the adapter 5. A procedure for attaching the adapter 5 to the wiring duct 3 will be described later.

[0056] The two mounting grooves 3112 are provided on the inner surface of the storage section 3110. Of the two fitting portions 3111 and the two mounting grooves 3112, the two fitting portions 3111 are provided closer to the opening of the storage section 3110. The two mounting grooves 3112 are formed along the longitudinal direction (left-right direction) of the duct rail 31. More specifically, the two mounting grooves 3112 are formed across both ends of the duct rail 31 in the longitudinal direction.

[0057] The two mounting grooves 3112 correspond one-to-one to the two second rails 312. A corresponding second rail 312 is fitted into each mounting groove 3112. In this way, the two second rails 312 are attached to the first rail 311. The first rail 311 has two protrusions 3113 for preventing the two second rails 312 from falling off.

[0058] Moreover, the first rail 311 further has a restricting protrusion 3114. The restricting protrusion 3114 is a protrusion. In Fig. 9, the restricting protrusion 3114 is provided on the upper side in the up-down direction of the first rail 311. The restricting protrusion 3114 can be inserted into the restricting recess 55 of the adapter 5.

[0059] Each of the two second rails 312 has a length in the left-right direction. The shape of the second rail 312 in a cross section perpendicular to the left-right direction is U-shaped. The second rail 312 has electrical insulation properties. The second rail 312 is formed of a synthetic resin material such as PVC (polyvinyl chloride). The second rail 312 holds the conductive bar 32 on its inner side.

[0060] Each of the two conductive bars 32 has a length in the left-right direction. Each of the two conductive bars 32 is provided across the right end to the left end of the duct rail 31. The two conductive bars 32 are electrically connected to the corresponding wiring W1 (see FIG. 13A) via the feed-in 4. One of the two conductive bars 32 of each wiring duct 3 is electrically connected to the positive wiring W1, and the other is electrically connected to the negative wiring W1. This allows DC power to be supplied to the two conductive bars 32.

[0061] (6) Feed-ins and end caps 11, the two feed-ins 4 correspond one-to-one to the two wiring ducts 3. The two end caps E1 correspond one-to-one to the two wiring ducts 3. The corresponding feed-in 4 is attached to one of the first and second longitudinal ends of each wiring duct 3, and the corresponding end cap E1 is attached to the other end.

[0062] The feed-in 4 is a configuration for electrically connecting the two conductive bars 32 of the wiring duct 3 to the corresponding wiring W1 (see FIG. 15). That is, the two conductive bars 32 are electrically connected to the corresponding wiring W1 via the feed-in 4. The configuration of the feed-in 4 will be described below with reference to FIG. 15.

[0063] The feed-in 4 includes an outer box 41 , a terminal box 42 , and two terminal units 43 .

[0064] The outer box 41 has a rectangular parallelepiped shape and houses a terminal box 42 therein.

[0065] The terminal box 42 has a first block 421 and a second block 422. The first block 421 and the second block 422 are joined together to form the terminal box 42. The terminal box 42 houses two terminal units 43. The terminal box 42 also has two wire entrance holes 423 into which two wires W1 are inserted. The two wire entrance holes 423 are provided in the first block 421.

[0066] Each of the two terminal units 43 includes a spring 431 and a terminal portion 432. A pair of the spring 431 and the terminal portion 432 configures a quick-connect terminal. That is, the terminal unit 43 includes a quick-connect terminal.

[0067] The spring 431 is formed by bending a metal plate. The terminal portion 432 is made of a metal plate and formed into a plate shape. The terminal portion 432 faces the spring 431. The two terminal units 43 correspond one-to-one to the two conductive bars 32. The terminal portion 432 of each terminal unit 43 is electrically connected to the corresponding conductive bar 32.

[0068] 16A and 16B , the wire W1 inserted into the terminal box 42 through the wire inlet hole 423 is sandwiched between the spring 431 and the terminal portion 432. As a result, the wire W1 is electrically connected to the terminal portion 432 and is held between the spring 431 and the terminal portion 432.

[0069] (7) Partition In this embodiment, as described above, the wiring duct system 100 includes a partition fixing structure S1 capable of fixing the partition 6. A "partition" is also called a room divider or a screen. The partition-equipped duct system 200 (see Figs. 7 to 10) includes the wiring duct system 100 and a plurality of (here, three) partitions 6 (6A, 6B, 6C).

[0070] Each partition 6 is fixed above the tabletop 71. This divides the space above the tabletop 71 into a front space and a rear space. Some people (hereinafter referred to as "first people") sit at the front of the desk 7, and some other people (hereinafter referred to as "second people") sit at the rear of the desk 7. Since the space between the first and second people is divided by the partitions 6, the possibility of droplet infection occurring between the first and second people can be reduced.

[0071] Each partition 6 has, for example, translucency. The material of each partition 6 is, for example, acrylic resin. The shape of each partition 6 is, for example, plate-like. The thickness direction of the partition 6 is along the front-rear direction. The planar shape of each partition 6 when viewed in the front-rear direction is rectangular. The fitting protrusion of each partition 6 protrudes downward from its main body and is inserted into the through hole in the corresponding partition fixing structure S1. This fixes each partition 6 to the wiring duct system 100. That is, the partition fixing structure S1 is a structure that fits with the partition 6 by the partition 6's own weight. Also, by removing the fitting protrusion from the partition fixing structure S1, each partition 6 can be removed from the wiring duct system 100. That is, the partition fixing structure S1 fixes the partition 6 in a detachable manner.

[0072] (8) Adapter 14, first fixing parts 1 are arranged on the front and rear of a partition 6, and each first fixing part 1 houses a wiring duct 3 (see FIG. 7). An adapter 5 is detachably attached to each of these two wiring ducts 3. The wiring duct system 100 supplies power to a connector 95 via the adapter 5.

[0073] 1, 2, and 4 to 9, the adapter 5 has a housing 51, an operation unit 52, an attachment protrusion 53, two power receiving terminals 54, a spring housed in the housing 51, and a cover 56 (see FIGS. 5B and 6). The adapter 5 further has a pair of connection connectors (e.g., a USB socket) and a circuit board, etc. housed in the housing 51. Here, the housing 51, the attachment protrusion 53, the two power receiving terminals 54, the pair of connection connectors, the circuit board, the cover 56, etc. of the adapter 5 configure the adapter main body 50.

[0074] The housing 51 is made of, for example, resin. The housing 51 is in the shape of a hollow box with one side (the rear side in Figs. 5 and 8, etc.) open. The lid portion 56 is attached to the housing 51 by screwing or the like so that the open side of the housing 51 is covered by the lid portion 56. The outer shape of the housing 51 is, for example, a rectangular parallelepiped in Fig. 1, etc., but is not limited thereto, and the outer shape of the housing 51 may be, for example, a cube, another polygonal prism shape, a cylinder shape, or the like, as long as it does not excessively deviate from the purpose of the present disclosure.

[0075] In this embodiment, the adapter 5 has a connector mounting surface 501, which is the surface of the adapter main body 50 to which the connector 95 is mounted, and a peripheral surface 510 other than the mounting surface 502 including the cover portion 56. The peripheral surface 510 can also be said to be surfaces that constitute the four side surfaces of the housing 51 when the adapter 5 is viewed in the front-rear direction, as shown in Fig. 1, for example.

[0076] Here, as shown in Figs. 1, 2, 4 to 9, the circumferential surface 510 of the adapter 5 will be described based on the posture of the adapter 5 in a state in which the adapter 5 is connected to the wiring duct 3 and the rotation of the adapter 5 is restricted (hereinafter, also referred to as a "rotation restricted state"). However, the posture of the adapter 5 is not limited to this. In this case, if a circumferential surface on one side of the surface along the longitudinal direction of the wiring duct 3 (the lower side in the up-down direction in Figs. 1, 2, 4, 5, 8, and 9) is defined as a first circumferential surface 5101, one circumferential surface intersecting with the first circumferential surface 5101 is defined as a second circumferential surface 5102, the other circumferential surface intersecting with the first circumferential surface 5101 (i.e., a surface different from the second circumferential surface 5102) is defined as a third circumferential surface 5103, and a circumferential surface intersecting with both the second circumferential surface 5102 and the third circumferential surface 5103 is defined as a fourth circumferential surface 5104. That is, the adapter 5 has a first circumferential surface 5101, a second circumferential surface 5102, a third circumferential surface 5103, and a fourth circumferential surface 5104. Also, as shown in Fig. 1, in the rotation restricted state, the first circumferential surface 5101 and the fourth circumferential surface 5104 are parallel to the longitudinal direction (left-right direction), and the second circumferential surface 5102 and the third circumferential surface 5103 are parallel to the width direction (up-down direction).

[0077] In this disclosure, the state in which the rotation of the adapter 5 is released from the above-mentioned rotation restricted state may be referred to as a "rotation restricted state". The rotation restricted state may also include a state in which the adapter 5 is being rotated. However, in the following description, the rotation restricted state is mainly described as a state in which the adapter 5 is rotated 90° counterclockwise from the rotation restricted state. In the rotation restricted state, each of the circumferential surfaces 510 is located at a position rotated 90° from the original position in the rotation restricted state. Also, as described later, a state in which the adapter 5 is installed in the wiring duct 3 and the restricting member 8 is not attached may be simply referred to as an "arranged state".

[0078] The housing 51 further includes a first socket 511 and a second socket 512. The first socket 511 is a socket for a USB Type-A plug serving as a connector 95 (see FIG. 17). The second socket 512 is a socket for a USB Type-C plug serving as a connector 95. That is, the first socket 511 is of a different standard from the second socket 512. The first socket 511 is of a different size from the second socket 512. In the housing 51, the pair of connection connectors are mounted on a circuit board so as to face the first socket 511 and the second socket 512 one-to-one. The connector 95 inserted into the first socket 511 or the second socket 512 is connected to the corresponding one of the pair of connection connectors and is electrically connected to the power receiving terminal 54 via the circuit board.

[0079] The first socket 511 and the second socket 512 are provided on a surface (connector mounting surface 501; front surface in FIG. 1 and the like) facing away from the wiring duct 3 when the adapter 5 is attached to the wiring duct 3. When the adapter 5 is attached to the wiring duct 3, the first socket 511 and the second socket 512 are lined up vertically as shown in FIGS. 1, 2, 5A, 6A, and 8.

[0080] The operating unit 52 is configured to be insertable and removable from the storage unit 3110, and configured to restrict rotation of the adapter 5 by inserting it into the storage unit 3110. The operating unit 52 is held by the housing 51. The operating unit 52 is made of, for example, resin. The operating unit 52 is plate-shaped. The operating unit 52 has a knob 521, and is held by the housing 51 in a manner in which the knob 521 is exposed from one side of the housing 51. Specifically, the knob 521 is disposed in a groove 522 provided in a part of one of the peripheral surfaces 510 of the housing 51 (for example, the second peripheral surface 5102 in FIG. 1). The groove 522 is formed in a concave shape on the peripheral surface so as to be closed in the front direction and open in the rear direction, and to be one step lower than the peripheral surface. The operation unit 52 is arranged so that the knob 521 can move in the front-rear direction, and the knob 521 is usually held so as to be accommodated in a groove 522 in the peripheral surface when the rotation is not restricted. That is, the operation unit 52 can slide in a predetermined direction (front-rear direction in FIG. 14) by applying a force to the knob 521 with a person's fingertip or the like. The operation unit 52 is held in the housing 51 in a state in which the return force of a spring stored in the housing 51 acts in a direction (rearward) away from the connector mounting surface 501. Therefore, when no force is applied to the operation unit 52, the claw 520 at the tip of the operation unit 52 protrudes from the housing 51 to the opposite side to the connector mounting surface 501 side. By applying a force forward against the force of the spring with a person's fingertip or the like to the knob 521, the operation unit 52 moves forward in the front-rear direction. In the above-mentioned rotation restricted state, the operation unit 52 is located on one side in the left-right direction (left side in FIG. 1). In the rotation restriction release state, the operation unit 52 is located in a direction other than the left-right direction (for example, on the lower side in the up-down direction in FIG. 2).

[0081] The lid portion 56 is made of, for example, resin. The lid portion 56 is in the shape of a rectangular plate. A mounting protrusion 53 is provided on the rear surface of the lid portion 56. As shown in Figs. 5B and 6, the lid portion 56 and the mounting protrusion 53 are formed as a continuous unit. The mounting protrusion 53 includes a shaft portion 531 and two fixing ribs 532. The shaft portion 531 protrudes from the housing 51 to the side opposite the connector mounting surface 501. The two fixing ribs 532 protrude from the side surfaces of the shaft portion 531. The two fixing ribs 532 protrude in opposite directions to each other.

[0082] The two power receiving terminals 54 protrude from the housing 51 on the side opposite to the connector mounting surface 501. The tip portions of the two power receiving terminals 54 are bent. The two power receiving terminals 54 are held by the mounting projection 53 such that the bent tip portions are exposed from the tip of the shaft portion 531 (see FIG. 6).

[0083] The adapter 5 has a recess (hereinafter also referred to as a "regulating recess 55" (see FIG. 5)) on the mounting surface 502 that is closer to the mounting surface 501 of the connector 95 than the mounting surface 502. Specifically, the restricting recess 55 is configured by a recess formed in the rear end face of the housing 51 and in the surface of the cover portion 56. As shown in FIGS. 5B and 6, the restricting recess 55 includes a first recess 551 and a second recess 552.

[0084] First recess 551 is formed in a partial area of ​​the end face on the rear side in the front-rear direction of housing 51, stepping down in a direction approaching connector mounting surface 501. In Fig. 5B and Fig. 6, the area of ​​first recess 551 is shown by thick dot hatching for easy understanding.

[0085] The second recess 552 is formed such that a partial area of ​​the surface on the rear side in the front-rear direction of the lid portion 56 is stepped down in a direction approaching the connector mounting surface 501. In Figs. 5B and 6, the area of ​​the second recess 552 is shown by light dot hatching for easy understanding. The bottom surface of the first recess 551 and the bottom surface of the second recess 552 are substantially flush with each other. In this way, the first recess 551 is included in the housing 51, and the second recess 552 is included in the lid portion 56.

[0086] When the adapter 5 is attached to the duct rail 31, the restricting protrusion 3114 (see FIG. 4) of the duct rail 31 is inserted into the restricting recess 55. If the adapter 5 is oriented in the wrong direction, for example, if the adapter 5 shown in FIG. 6 is oriented upside down, the restricting protrusion 3114 interferes with an area protruding one step further than the restricting recess 55 on the rear surface of the adapter 5, and the adapter 5 cannot be attached to the duct rail 31. In other words, the restricting recess 55 and the restricting protrusion 3114 restrict the orientation of the adapter 5 when the adapter 5 is attached to the duct rail 31.

[0087] The mounting surface 502 is a surface that faces the wiring duct 3 when the adapter 5 is attached in the wiring duct system 100. As shown in FIG. 6 and other figures, the mounting surface 502 can also be said to be the rear surface on the rear side in the front-rear direction when placed on the wiring duct 3. In other words, the mounting surface 502 can be said to be the surface opposite to the connector mounting surface 501, which is the front surface in the front-rear direction of the adapter 5. The diagram shown in the balloon in FIG. 6 is a rear view showing a part of the rear side of the connector 95 in the rotation restriction release state. In the diagram shown in the balloon in FIG. 6, the wiring duct 3 is shown by a two-dot chain line in order to show it transparently for convenience.

[0088] The mounting surface 502 includes the lid portion 56 and may also include elements constituting the lid portion 56. The mounting surface 502 also includes the peripheral edge of the housing 51 on the rear side in the front-rear direction. The peripheral edge of the housing 51 on the rear side in the front-rear direction includes the above-mentioned first recess 551. Therefore, the mounting surface 502 may have a surface that is not entirely in contact with the wiring duct 3 when the adapter 5 is arranged. Specifically, for example, as shown in FIG. 5B and FIG. 6, a portion of the mounting surface 502 where the restricting recess 55 formed at a lower position in the lid portion 56 is located is not in direct contact with the wiring duct 3, and as a result, a gap is formed between the adapter 5 and the wiring duct 3.

[0089] The adapter 5 further includes a power converter (not shown). A plurality of electronic components constituting the power converter are mounted on a circuit board inside the housing 51. The power converter converts the power received at the two power receiving terminals 54 into power of a desired voltage. The power converted by the power converter is output from a pair of connecting connectors (USB sockets). An electric device 94 (see FIG. 17) can receive power via a cable including a connector 95 (see FIG. 18) that is inserted into the first socket 511 or the second socket 512 and connected to the connecting connector.

[0090] The procedure for attaching the adapter 5 to the wiring duct 3 will be described below.

[0091] As described above, the adapter 5 has the fixing rib 532. In Figures 4 to 6 and 9, the two fixing ribs 532 are aligned vertically in the rotation restricted state. In the rotation unrestricted state, the two fixing ribs 532 are aligned horizontally.

[0092] First, as shown in Fig. 6 and Fig. 7, the worker holds the adapter 5 so that the direction in which the two fixing ribs 532 are aligned is along the longitudinal direction (left-right direction) of the duct rail 31. In this state, the surface of the knob portion 521 of the operation part 52 faces downward in the up-down direction (see Fig. 6 and Fig. 7). In this state, the two fixing ribs 532 do not interfere with the duct rail 31, and the mounting projection 53 can be inserted into the storage part 3110 of the duct rail 31 along the insertion direction A1 (rearward). At this time, the claw portion 520 at the tip of the operation part 52 comes into contact with the first fixing part 1, and moves toward the connector mounting surface 501 side (forward) due to the contact pressure of the first fixing part 1.

[0093] As shown in Figs. 6 and 7, after inserting the mounting projection 53 into the storage section 3110, the worker rotates the adapter 5 clockwise by 90 degrees around the rotation axis B1. The rotation axis B1 shown in Figs. 6 and 7 is an imaginary axis and is approximately coincident with the central axis of the shaft section 531. Then, as shown in Fig. 9, the two fixing ribs 532 are inserted into the two fitting sections 3111. This restricts the movement of the adapter 5 in the front-rear direction. Also, as shown in Fig. 9, the operation section 52, more specifically, the claw section 520 of the operation section 52 is inserted into the storage section 3110 of the duct rail 31, thereby restricting the rotation of the adapter 5. Also, the two power receiving terminals 54 come into contact with the corresponding conductive bars 32, and are thus electrically connected to the corresponding conductive bars 32. In short, the adapter 5 is inserted with its fixed rib 532 into the storage section 3110 and rotated a predetermined angle (e.g., 90 degrees) around the rotation axis B1 along the insertion direction A1, thereby achieving electrical connection with the conductive bar 32 and preventing it from being pulled out of the storage section 3110.

[0094] Through the above-mentioned procedure, the adapter 5 is attached to the wiring duct 3. The adapter 5 can be attached to the wiring duct 3 at any position within the region where the storage section 3110 is provided (the attachment region that is continuous in the longitudinal direction of the wiring duct 3). The adapter 5 can also be electrically connected to the conductive bar 32.

[0095] In this embodiment, the adapter 5 is not provided with a configuration for restricting the left-right movement of the adapter 5 attached to the wiring duct 3. Therefore, the adapter 5 can move left-right while attached to the wiring duct 3. In other words, the adapter 5 can move along the longitudinal direction of the wiring duct 3 after attachment. However, in order to suppress wear of the two power receiving terminals 54 caused by the left-right movement of the adapter 5, the wiring duct system 100 may be provided with a configuration for restricting the left-right movement of the adapter 5 attached to the wiring duct 3. Note that the movement includes, for example, a sliding movement that does not change the position of the adapter 5 in the up-down direction, but slides and changes the position only in the left-right direction.

[0096] Next, a procedure for removing the adapter 5 from the wiring duct 3 will be described. When the worker applies force to the knob portion 521 of the operation portion 52 of the adapter 5 in the arranged state toward the connector mounting surface 501, the operation portion 52 can also be moved toward the connector mounting surface 501, and the claw portion 520 comes out of the storage portion 3110. In this way, the restriction on the rotation of the adapter 5 is released. When the worker rotates the adapter 5 counterclockwise by 90 degrees, the two fixing ribs 532 come out of the two fitting portions 3111. Then, the adapter 5 is removed from the wiring duct 3 by pulling it out toward the user (for example, toward the front in the front-rear direction).

[0097] (9) Power supply system Next, with reference to FIG. 18, an example of the configuration of a system (including the wiring duct system 100) that supplies power to the electric device 94 will be described.

[0098] A switching hub 92 and a splitter 93 are provided in a facility where an electrical device 94 is used. The switching hub 92 is electrically connected to a power source 91. The power source 91 supplies AC power to the switching hub 92. The power source 91 is, for example, a commercial power source or a distributed power source.

[0099] The switching hub 92 is a PoE switching hub compatible with PoE (Power over Ethernet). The switching hub 92 is electrically connected to a splitter 93 via a LAN (Local Area Network) cable. The switching hub 92 can also be electrically connected to devices compatible with PoE. Examples of devices compatible with PoE include computer terminals, network cameras, IP (Internet Protocol) telephones, and wireless access points. The switching hub 92 can transmit and receive PoE signals including data and power (DC power) between the devices electrically connected to the switching hub 92.

[0100] The splitter 93 is a PoE splitter that supports PoE. The splitter 93 separates the PoE signal received from the switching hub 92 into data and power (DC power). The splitter 93 supplies the power separated from the PoE signal to a device that does not support PoE. As an example, the splitter 93 supplies the power separated from the PoE signal to one or more electric devices 94 that do not support PoE via the wiring duct system 100.

[0101] Furthermore, the splitter 93 transmits a data signal including the data separated from the PoE signal to a device that does not support PoE.

[0102] The DC power output terminal of the splitter 93 is electrically connected to a first end of each of the four wirings W1. One of the two wiring ducts 3 corresponds to two of the four wirings W1, and the other wiring duct 3 corresponds to the remaining two wirings W1. The following description focuses on one of the wiring ducts 3, and the two wirings W1 and one feed-in 4 corresponding to this wiring duct 3.

[0103] The two wires W1 are a positive wire and a negative wire. The two wires W1 correspond one-to-one to two wire inlet holes 423 (see FIG. 14 ) provided in the feed-in 4. The two wires W1 also correspond one-to-one to two conductive bars 32 of the wiring duct 3. A second end of each of the two wires W1 is inserted into the corresponding wire inlet hole 423 and electrically connected to the corresponding conductive bar 32. One or more adapters 5 can be connected to the wiring duct 3, and one or more electric devices 94 can be electrically connected to each conductive bar 32 via the adapter 5.

[0104] As a result, each electric device 94 can receive power supplied from the wiring W1 via the conductive bar 32 and the adapter 5. A user can use the electric device 94 on or around the desk 7 (see FIG. 10 ).

[0105] It is preferable that the DC voltage (the voltage between the two conductive bars 32) that the adapter 5 receives from the two conductive bars 32 is 60 V or less. In this case, there is an advantage that no qualification such as an electrician is required when installing the adapter 5. Therefore, it is possible to easily secure a power source compared to relocating or installing a new AC 100 V outlet.

[0106] It is more preferable that the DC voltage that the adapter 5 receives from the two conductive bars 32 is 24 V or less. It is also preferable that the DC voltage that the adapter 5 receives from the two conductive bars 32 is 48 V or less.

[0107] As an example, the DC voltage of the PoE signal output from the switching hub 92 is 48 V. The splitter 93 has a function of stepping down the DC voltage of the PoE signal received from the switching hub 92, and the DC voltage output from the splitter 93 is, for example, 24 V. The adapter 5 receives the DC voltage output from the splitter 93 and outputs a DC voltage of 24 V or less to the electric device 94.

[0108] By setting the voltage between the two conductive bars 32 of the wiring duct 3 to 60 V or less (for example, 24 V), it is possible to reduce the possibility of a user receiving an electric shock when touching the conductive bar 32. This has the advantage that it is not necessary to provide a cover on the wiring duct 3, and therefore the work of attaching the adapter 5 to the wiring duct 3 does not require the time and effort of attaching and detaching the cover.

[0109] An example of the configuration of a system for supplying power to the electrical device 94 has been described above, but instead of this system, a simpler system may be used in which, for example, each wiring W1 is connected to a commercial power outlet via an AC adapter.

[0110] (10) Regulatory components In the present embodiment, in the wiring duct system 100, the restricting member 8 includes the flat plate portion 80 and the switching portion 82 as described above. In the wiring duct system 100, the end surface portion 81 of the restricting member 8 contacts at least a part of the adapter 5. As shown in FIGS. 1, 5A, 6, etc., the end surface portion 81 of the flat plate portion 80 of the restricting member 8 contacts a part of the operating portion 52 of the adapter 5.

[0111] The restricting member 8 is made of, for example, a metal plate material. The method of making the restricting member 8 is not particularly limited, but for example, the restricting member 8 can be made by punching a metal plate material into a shape having an appropriate configuration to make a flat plate-like portion 80 having an end surface portion 81 and a switching portion 82, and combining the flat plate-like portion 80 and the switching portion 82. The restricting member 8 may also be made of the flat plate-like portion 80 and the switching portion 82 as a single unit. The material of the restricting member 8 is not limited to metal, and may be made of thermoplastic resin such as plastic, thermosetting resin, or the like.

[0112] As shown in FIG. 3A to FIG. 3D, the flat plate-like portion 80 is made of a flat plate. Specifically, the flat plate-like portion 80 is a substantially flat plate-like member having a thickness that is thin relative to the longitudinal length. The thickness here refers to the thickness in the plate thickness direction, which is a direction perpendicular to the mounting surface 502 of the adapter 5. That is, as shown in FIG. 1, the plate thickness direction of the flat plate-like portion 80 in this embodiment is the depth direction (front-rear direction), which is a direction perpendicular to the longitudinal direction (left-right direction) of the wiring duct 3. The plate thickness of the flat plate-like portion 80 is smaller than the thickness of the adapter 5 in the direction facing the mounting surface 502 of the adapter 5, that is, the length of the adapter 5 in the depth direction. In this case, it is easy to make it difficult to take out and place the adapter 5 while maintaining the strength of the regulating member 8. In addition, in this case, it is easy to contribute to the miniaturization of the regulating member 8 (for example, space saving in the thickness direction) and reduction of manufacturing costs.

[0113] The flat portion 80 has a flat front portion 801 that faces the near side in the depth direction (the front side in the front-to-back direction) and a flat rear portion 802 that faces the far side in the depth direction (the rear side in the front-to-back direction). The flat front portion 801 and the flat rear portion 802 are connected via the end surface portion 81.

[0114] The flat plate portion 80 includes an end surface portion 81 that covers at least a part of the adapter 5. The end surface portion 81 is not on the front and back surfaces of the flat plate portion 80, i.e., the flat plate front portion 801 and the flat plate back portion 802, but on a surface that constitutes a part of the surface that constitutes the thickness of the flat plate portion 80. In this embodiment, the plate thickness direction of the flat plate portion 80 is a direction perpendicular to the mounting surface 502 of the adapter 5 that is mounted in the wiring duct system 100. In other words, the end surface portion 81 is formed along the plate thickness direction. Therefore, in this embodiment, the plate thickness portion that constitutes the end surface portion 81 contacts at least a part of the peripheral surface 510 of the adapter 5.

[0115] The end surface portion 81 can act to restrict left-right movement of the adapter 5. Specifically, the end surface portion 81 includes a contact surface 810 that comes into contact with at least a part of the circumferential surface 510 of the adapter 5 when the adapter 5 is in a rotation restricted state or when the switching unit 82 is in a locked state or an unlocked state. The contact surface 810 can be a surface that comes into one-to-one contact with the circumferential surface 510 of the adapter 5 when the adapter 5 is in the rotation restricted state.

[0116] In this embodiment, the flat portion 80 comes into contact with the operating portion 52, which is at least a part of the adapter 5, thereby restricting removal of the adapter 5, but the end surface portion 81 has one or more contact surfaces 810 that come into contact with the peripheral surface 510 of the adapter 5, thereby more firmly restricting removal of the adapter 5. In this embodiment, the end surface portion 81 includes three contact surfaces 810 (811, 812, 813).

[0117] Here, as described in the above description of (8) Adapter, contact surface 810 of restricting member 8 will be described with reference to the attitude of adapter 5 in the rotation restricted state. Note that the rotation restricted state includes both the locked state and the unlocked state. This is because the rotation restricted state here simply refers to a state in which the rotation of adapter 5 is restricted or not, regardless of restricting member 8.

[0118] The contact surface 810 in the end surface portion 81 includes a first contact surface 811, a second contact surface 812, and a third contact surface 813. The first contact surface 811 is a surface that contacts the first peripheral surface 5101 of the adapter 5. In the rotation restricted state, the first contact surface 811 can contact at least a part of the first peripheral surface 5101 to hold the adapter 5. The second contact surface 812 is a surface that contacts the second peripheral surface 5102 of the adapter 5. In the rotation restricted state, the second contact surface 812 can contact at least a part of the second peripheral surface 5102 to hold the adapter 5. Therefore, the restricting member 8 can fix the adapter 5 more firmly. In this case, a part of the second contact surface 812 can also contact the operating unit 52 of the adapter 5. In this embodiment, the third contact surface 813 is a surface that contacts the end surface 550 of the restricting recess 55. Specifically, the end surface 550 is a boundary surface (end surface 550) in the front-rear direction between a second recess 552 formed by lowering a partial area of ​​the surface on the front-rear direction rear side of the cover portion 56 one step in the direction approaching the connector mounting surface 501, and a portion 561 that is one step higher toward the connector mounting surface 501 than the second recess 552. The third contact surface 813 enters the restricting recess 55 and contacts at least a part of the end surface 550 to hold the adapter 5. Therefore, in this embodiment, the third contact surface 813 does not contact the third circumferential surface 5103 of the adapter 5.

[0119] The flat portion 80 has a flat vertical piece 8011, a flat horizontal piece 8012, and a flat bent piece 8013. The flat vertical piece 8011, the flat horizontal piece 8012, and the flat bent piece 8013 are integrally formed. The flat vertical piece 8011 is a piece extending in the width direction (up-down direction), and one end thereof is connected to the flat horizontal piece 8012. The flat horizontal piece 8012 is a piece extending in the longitudinal direction (left-right direction), and one end thereof is connected to the flat vertical piece 8011 and the other end is connected to the flat bent piece 8013. The flat bent piece 8013 is a piece extending in the up-down direction, and one end thereof is connected to the flat horizontal piece 8012. The flat vertical piece 8011 and the flat horizontal piece 8012 are configured to be substantially perpendicular to each other, and the flat horizontal piece 8012 and the flat folded piece 8013 are configured to be substantially perpendicular to each other. The flat vertical piece 8011 and the flat folded piece 8013 are configured to be substantially parallel to each other. In this embodiment, in the rotation restricted state of the adapter 5, the tip of the flat folded piece 8013 is disposed between the restricting recess 55 of the adapter 5 and the wiring duct 3, and is in contact with the surface connecting the mounting surface 502 and the restricting recess 55.

[0120] The flat portion 80 is generally U-shaped when viewed from the front when the restricting member 8 is attached. In this embodiment, the width direction length of the flat bent piece 8013 is shorter than the width direction length of the flat vertical piece 8011. The flat portion 80 is configured so that when the restricting member 8 is attached, it comes into contact with both side surfaces in the longitudinal direction of the housing 51 of the adapter 5 with almost no gap, or so that there is a small gap.

[0121] A switching portion 82 is formed in a portion of the flat vertical piece 8011. In Fig. 1 and other figures, the switching portion 82 is formed in a portion of the flat vertical piece 8011 closer to the upper and lower upward sides.

[0122] One end surface of the flat horizontal piece 8012 may be a first contact surface 811 , one end surface of the flat vertical piece 8011 may be a second contact surface 812 , and one end surface of the flat bent piece 8013 may be a third contact surface 813 .

[0123] The switching portion 82 has a head portion 820, a switching shaft portion 822, and a cam portion 823. Specifically, the switching portion 82 is configured with a through hole (not shown) penetrating, for example, the flat vertical piece 8011 of the flat portion 80 from its front surface to its back surface, a switching shaft portion 822 passing through the through hole, and a cam portion 823 located on the opposite side to the tip of the switching shaft portion 822 and capable of engaging to switch between locking and unlocking.

[0124] A keyhole 821 is formed in the head 820 at the tip of the switching shaft 822. For example, the head 820 has a screw-head-shaped keyhole 821. In this embodiment, as shown in FIG. 1 and the like, the head 820 has a cross-shaped keyhole 821. In this case, the switching unit 82 can be switched using a tool having a shape similar to that of a keyhole, such as a Phillips screwdriver. That is, the switching unit 82 is configured to be capable of being switched using a tool. The head 820 is configured in a shape having a diameter or dimension larger than the outer diameter of the switching shaft 822.

[0125] The switching shaft portion 822 is formed along a direction perpendicular to the flat front portion 801 and the flat rear portion 802 of the flat portion 80 .

[0126] The cam portion 823 is formed in a flat plate shape. The cam portion 823 is fixed to the tip of the switching shaft portion 822 on the side opposite to the side where the head portion 820 is located. The plate thickness of the cam portion 823 is approximately the same as the plate thickness of the flat portion 80. The cam portion 823 is provided away from the flat rear portion 802, that is, there is a gap between the cam portion 823 and the flat rear portion 802.

[0127] In the wiring duct system 100, when the restricting member 8 is attached, the restricting member 8 covers at least a part of the adapter 5 as described above. Here, the restricting member 8 can restrict removal of the adapter 5 by covering the operating portion 52, which is at least a part of the adapter 5, with the second contact surface 812 at the end surface portion 81. In addition, in this embodiment, a part of the first contact surface 811 also covers at least a part of the first circumferential surface 5101 of the adapter 5. In addition, a part of the second contact surface 812 covers at least a part of the second circumferential surface 5102 of the adapter 5. Furthermore, a part of the third contact surface 813 contacts at least a part of the mounting surface 502 in the restricting recess 55 of the adapter 5. As a result, a part of the circumferential surface of the adapter 5 is covered by the restricting member 8. Therefore, removal of the adapter 5 can be more firmly restricted. In this embodiment, in the regulating member 8, a flat bent piece 8013 having a third contact surface 813 is accommodated between the third peripheral surface 5103 and the end surface 550 in the regulating recess 55. That is, the tip of the flat bent piece 8013 is disposed between the regulating recess 55 and the wiring duct 3, and is in contact with the surface connecting the mounting surface 502 and the regulating recess 55. This makes it possible to make a part of the regulating member 8 supporting the adapter 5 invisible. Therefore, it is possible to make it difficult to excessively impair the appearance of the wiring duct system 100. In addition, in this case, it is difficult for a user's finger to be inserted between the adapter 5 and the duct rail 31, and it is possible to make the structure more difficult to remove. Therefore, it is easy to exert a high deterrent force against the removal of the adapter 5. In the above, it has been described that a part of the regulating member is not visible in the locked state, but a part of the regulating member may be made not visible even in the unlocked state. For example, even if it is not in the locked state, a part of the regulating member 8, for example, the flat bent piece 8013, may be hidden.

[0128] The restricting member 8 can restrict removal of the adapter 5 from the wiring duct system 100 based on the flat plate-shaped portion 80 and the switching portion 82 of the restricting member 8 and the switching key K1. A lock system using the restricting member 8 of this embodiment will be described below.

[0129] (11) Lock system Hereinafter, a system for controlling the locked and unlocked states using a restricting member 8 according to this embodiment (referred to as a "lock system" in this disclosure) will be described in detail with reference to Figs. 1 to 6.

[0130] 1, the lock system includes a restricting member 8 and a switching key K1. As already described, the restricting member 8 is a member that restricts removal of the adapter 5 from the wiring duct system 100. The restricting member 8 includes a flat plate-shaped portion 80 and a switching portion 82. Here, as an example, the flat plate-shaped portion 80 and the switching portion 82 are formed integrally.

[0131] Hereinafter, the state in which the restricting member 8 is attached to the wiring duct system 100 and restricts removal of the adapter 5 as shown in FIG. 1 may be simply referred to as "when the restricting member 8 is in use."

[0132] The switching key K1 is a member for performing a switching operation on the switching portion 82 of the regulating member 8. When the head portion 820 of the switching portion 82 has a keyhole portion 821, specifically when the head portion 820 is formed as a keyhole, the switching key K1 is, for example, a round key (a so-called Ace key). By inserting the switching key K1 into the keyhole portion 821 of the switching portion 82 and turning it, the state of the switching portion 82 is switched from an unlocked state to a locked state, or from a locked state to an unlocked state. The type of the switching key K1 is not particularly limited, and may be a disk cylinder or the like. In addition, the switching key K1 may have a spare key.

[0133] In this embodiment, in the switching unit 82, the head portion 820 has a cross-shaped keyhole portion 821 as an example. In this case, the switching key K1 can be a tool such as a Phillips head screwdriver. Therefore, a tool corresponding to the shape of the switching unit 82 can be used as the switching key K1 for operating the switching unit 82. That is, the switching unit 82 is configured so that a switching operation can be performed with a tool. Therefore, since the switching between locking and unlocking of the switching unit 82 is performed with a tool, it can be made more difficult for a person (user, etc.) to easily remove the restricting member 8 and the adapter 5. Note that the tool that can be the switching key K1 is not limited to the Phillips head screwdriver, and may be appropriately changed according to the configuration of the switching unit 82 of the restricting member 8.

[0134] The procedure for using the restricting member 8 in the lock system will now be described.

[0135] First, the worker attaches the adapter 5 to the wiring duct 3. Next, the worker holds the restricting member 8, and places the restricting member 8 over the adapter 5 from below in the vertical direction so that the end surface 81 of the flat plate-shaped portion 80 of the restricting member 8 contacts at least a part of the peripheral surface 510 of the adapter 5 (see FIGS. 1 and 2, etc.).

[0136] Here, when the switching portion 82 is in the unlocked state, as shown in Figures 2 and 3, the long axis of the cam portion 823 is aligned along the longitudinal direction (left-right direction) of the duct rail 31. Also, even before the regulating member 8 is installed, the cam portion 823 is in a state other than the state in which the long axis is aligned along the width direction (up-down direction) of the duct rail 31. Therefore, when in the unlocked state, with the end surface portion 81 of the flat plate-shaped portion 80 surrounding the adapter 5, the cam portion 823 can be inserted into the storage portion 3110 of the wiring duct 3 along the insertion direction A1.

[0137] Then, the worker inserts the switching key K1 into the keyhole 821 and turns it, for example, clockwise. Then, as shown in FIG. 1, FIG. 3B, and FIG. 3C, the cam portion 823 connected to the switching shaft portion 822 rotates and the long axis of the cam portion 823 is aligned along a direction (up-down direction) perpendicular to the longitudinal direction of the duct rail 31, and the switching portion 82 is switched from the unlocked state to the locked state. As a result, the cam portion 823 fits into the two fitting portions 3111 of the first rail 311 in the wiring duct 3 as shown in FIG. 4. That is, the fitting portions 3111 into which the two fixing ribs 532 of the adapter 5 fit are also used as fitting portions for the cam portion 823. In the locked state, the restricting member 8 cannot be pulled out of the storage portion 3110 of the wiring duct 3 with the end surface portion 81 in contact with a part of the circumferential surface 510 of the adapter 5. 1, the end surface 81 of the restricting member 8 contacts the first circumferential surface 5101, the second circumferential surface 5102, and the end surface of the restricting recess 55 of the adapter 5, and the restricting member 8 is fixed to the wiring duct 3. In this way, the attachment of the restricting member 8 to the wiring duct 3 is achieved.

[0138] Furthermore, when the switching portion 82 is switched to the locked state, the flat portion 80 is attached to the wiring duct 3 in a manner that covers a part of the adapter 5, in this case, the underside (first peripheral surface 5101 of the adapter 5), the left side (second peripheral surface 5102 of the adapter 5) of the housing 51, and the end face of the regulating recess 55 in the cover portion 56, as shown in FIG. 1, thereby restricting the removal of the adapter 5.

[0139] When removing the restricting member 8, the worker inserts the switching key K1 again into the keyhole portion 821 and turns it, for example, counterclockwise, thereby switching the switching portion 82 from the locked state to the unlocked state. Then, the worker grasps the restricting member 8 and moves it toward himself (in the opposite direction to the insertion direction A1), thereby pulling the cam portion 823 out of the storage portion 3110 of the wiring duct 3. In this state, the worker can pull the restricting member 8 downward to detach the restricting member 8 from the adapter 5. Note that the procedure for using the restricting member 8 is not limited to the above-mentioned order.

[0140] As can be understood from the above description, the restricting member 8 of this embodiment can be said to provide two types of restrictions on removal of the adapter 5.

[0141] First, when the switching portion 82 is in the locked state, the restricting member 8 inhibits the rotation of the adapter 5 by the flat portion 80, and restricts the removal of the adapter 5. Specifically, when the restricting member 8 is in use, the end surface portion 81 of the flat portion 80 contacts the peripheral surface 510 of the adapter 5 and the end surface of the restricting recess 55, and is in a state of surrounding the adapter 5. Therefore, even if the adapter 5 is pulled out by rotating it counterclockwise, the housing 51 is surrounded by the end surface portion 81, and thus the rotation of the adapter 5 is inhibited. However, as described above, the claw portion 520 of the operating portion 52 is inserted into the storage portion 3110, and therefore the rotation of the adapter 5 is also prevented by the operating portion 52. Therefore, the rotation of the adapter 5 is more firmly inhibited.

[0142] Secondly, when the restricting member 8 is in use, the flat-plate portion 80 covers and conceals a part of the surface (particularly the knob portion 521) of the operation unit 52. This makes it difficult for a person (such as a user) to operate the operation unit 52 with a fingertip or the like. In other words, in this embodiment, the end surface portion 81 of the flat-plate portion 80 is configured to cover the operation unit 52 so as to hinder operation of the operation unit 52 when the switching portion 82 is in the locked state.

[0143] In this embodiment, the adapter 5 can move along the longitudinal direction of the wiring duct 3. The restricting member 8 can move along the longitudinal direction together with the adapter 5 when the switching unit 82 is in the locked state. That is, the cam unit 823 is engaged with the two engagement units 3111 of the first rail 311 in the wiring duct 3, so that pulling out is restricted, but the restricting member 8 can slide left and right along the two engagement units 3111. Here, the restricting member 8 can slide together with the adapter 5 because the end surface unit 81 can surround the adapter 5. Therefore, the restriction on removal of the adapter 5 can be maintained while improving the convenience of the user who uses the power supply from the wiring duct system 100.

[0144] However, when the adapter 5 is immovable in the longitudinal direction of the wiring duct 3, the restricting member 8 may also be immovable in the longitudinal direction of the wiring duct 3. Furthermore, the configuration of contacting two or more of the circumferential surfaces 510 of the adapter 5 may also be omitted. In this case, the flat plate portion 80 may have a second contact surface 812 of the end surface portion 81 that covers a part of the surface of the operating portion 52, and the first contact surface 811 and the third contact surface 813 may be omitted as appropriate.

[0145] Moreover, the operating unit 52 of the adapter 5 in this embodiment is not an essential component. Even if the operating unit 52 is not provided on the adapter 5, the restricting member 8 has an end surface portion 81 surrounding the adapter 5, and thus can hinder the rotation of the adapter 5 and restrict removal of the adapter 5.

[0146] (12) Advantages In this embodiment, by connecting a connector 95 of the electric device 94 (or a cable connected to the electric device 94) to an adapter 5 attached to the wiring duct 3, it is possible to supply power to the electric device 94 from the wiring duct 3. This improves the management of wiring around the fixtures compared to a case where power is supplied to the electric device 94 from a power outlet or a power tap that distributes power from a power outlet. In addition, by replacing the adapter 5 with another adapter having a different output voltage to the connector 95, the voltage supplied to the electric device 94 can be easily changed.

[0147] As described above, the wiring duct system 100 that supplies DC or AC power may be installed in a location that is relatively easy for a user to reach, such as a desk 7 or other fixture. In this case, the user may take the adapter 5 out of the wiring duct 3 without permission. In particular, when the wiring duct system 100 is applied to fixtures in a public facility such as a library, a hotel, or a private lodging, the users are an unspecified number of people, and there is a heightened concern that the adapter may be taken out.

[0148] In contrast, the restricting member 8 of the present embodiment includes a switching unit 82, and restricts removal of the adapter 5 from the wiring duct system 100. Therefore, unless the switching unit 82 is set to the unlocked state by the switching key K1, the restricting member 8 restricts removal of the adapter 5. As a result, it becomes difficult for the adapter 5 to be taken out of the wiring duct 3.

[0149] In addition, in this embodiment, it is assumed that the adapter 5 is configured to be attached and detached by rotation, and the end surface portion 81 of the flat portion 80 inhibits rotation of the adapter 5, so that despite the simple configuration, the adapter 5 is less likely to be removed.

[0150] Furthermore, in this embodiment, on the premise that the adapter 5 is attached and detached by rotation and the rotation is restricted by the insertion of the operating part 52, the operation of the operating part 52 is hindered by the flat part 80. Therefore, even though the configuration is simple, the adapter 5 is less likely to be taken out. In addition, in this embodiment, although the plate thickness of the restricting member 8 is formed relatively thin compared to the conventional one, the strength can be improved. Therefore, deformation due to forcibly removing the restricting member is less likely to occur. This makes it more difficult to take out the adapter due to theft, etc.

[0151] In particular, in this embodiment, when the wall portion K2 is configured to sandwich both ends of the adapter 5 in the longitudinal direction of the wiring duct 3, the adapter 5 can be further prevented from being taken out.

[0152] (Modification of the embodiment) Below, we will list some modified examples of the first embodiment. The following modified examples may be implemented in appropriate combination.

[0153] Some components of the wiring duct system 100 may be provided independently of other components. For example, the wiring duct 3, the duct fixture F1, the first fixing portion 1, or the second fixing portion 2 (fixing member) may be provided independently of other components.

[0154] The number of each component shown in the embodiment is an example, and is not limited to the number shown in the embodiment. For example, the wiring duct system 100 is not limited to having two wiring ducts 3, and may have one or three or more wiring ducts 3. The wiring duct system 100 is not limited to having two first fixing parts 1, and may have one or three or more first fixing parts 1. The wiring duct system 100 is not limited to having two second fixing parts 2, and may have one or three or more second fixing parts 2. The partition-equipped duct system 200 is not limited to having three partitions 6, and may have one, two, or four or more partitions 6.

[0155] The multiple wiring ducts 3 may include two or more wiring ducts 3 arranged in the vertical direction. Furthermore, the voltage of the conductive bar 32 may be different for each of the two or more wiring ducts 3. Furthermore, the standard of the attachable adapter 5 may be different for each of the two or more wiring ducts 3. For example, the two or more wiring ducts 3 may be different in the width or depth of the storage section 3110, so that the shape of the attachable adapter 5 may be limited for each of the two or more wiring ducts 3. In this case, there may be multiple types of restricting members K1 according to the shapes of the adapter 5.

[0156] The plate thickness of the regulating member 8 may be any appropriate dimension, but is preferably shorter than, for example, the length in the depth direction of the adapter 5. In this case, the regulating member 8 can be made smaller and the manufacturing costs can be reduced.

[0157] When attaching the restricting member 8, the end surface portion 81 of the restricting member 8 may be configured to surround the upper surface and both left and right side surfaces of the adapter 5, or to surround the entire circumferential surface in the top, bottom, left and right directions. For example, in the embodiment, the restricting member 8 is disposed so as to surround the adapter 5 from the bottom in the vertical direction, but the restricting member 8 may also be disposed so that the end surface portion 81 comes into contact with the fourth circumferential surface 5104 of the adapter 5 from the top in the vertical direction.

[0158] The keyhole portion 821 of the switching portion 82 is not limited to facing the front when the switching portion 82 is switched in the regulating member 8. In addition, the position of the switching portion 82 is on the left side in the left-right direction in the embodiment, but may be on the right side.

[0159] As an example, the switching unit 82 may be a so-called cylinder lock. As described above, the switching unit 82 has a keyhole portion 821 into which the switching key K1 is inserted. The switching unit 82 is held by the flat plate portion 80 with the keyhole portion 821 facing forward. The switching unit 82 also has a cam portion 823 that fits into the wiring duct 3 in the locked state. The cam portion 823 is attached to a switching shaft portion 822 that is the cylinder portion of the switching unit 82.

[0160] When the restricting member 8 has the third contact surface 813, it does not have to be disposed between the restricting recess 55 of the adapter 5 and the wiring duct 3. In this case, the third contact surface 813 may be in contact with the third circumferential surface of the adapter. That is, in the embodiment, the flat bent piece 8013 of the restricting member 8 is stored between the adapter 5 and the duct rail 31 and is not visible, but the flat bent piece 8013 of the restricting member 8 may be visible. More specifically, for example, as shown in FIG. 19, when the circumferential surface 510 of the adapter 5 along the longitudinal direction of the wiring duct 3 in the locked state is the first circumferential surface 5101, the end surface portion 81 of the restricting member 8 has the first contact surface 811, the second contact surface 812, and the third contact surface 813. The first contact surface 811 is a surface that contacts the first circumferential surface 5101. The second contact surface 812 is a surface that comes into contact with the second peripheral surface 5102. The third contact surface 813 is a surface that comes into contact with the third peripheral surface 5103. In this case, even if the restricting recess 55 is not formed in the cover portion 56 of the adapter 5, the adapter 5 can be more firmly restricted from being removed because the adapter 5 can come into contact with the peripheral surfaces at both ends, and, if necessary, with each of the three peripheral surfaces. Although the appearance may be inferior compared to the embodiment because the flat bent piece 8013 (for example, the tip of the flat bent piece 8013) in the portion including the third contact surface 813 can be seen, a strong restriction is possible, and the effect of preventing the adapter 5 from being taken away can be enhanced.

[0161] The flat plate portion 80 may be configured to sandwich both ends of the adapter 5. In this case, the second contact surface 812 contacts the second circumferential surface 5102 of the adapter 5, and the third contact surface 813 contacts the third circumferential surface 5103 of the adapter 5, respectively, to sandwich both ends of the adapter 5, i.e., the portions on the second circumferential surface 5102 and the third circumferential surface 5103.

[0162] Two or more wiring ducts 3 may be fixed to one first fixing portion 1. Alternatively, one wiring duct 3 may be fixed to two or more first fixing portions 1.

[0163] Two or more wiring ducts 3 may be connectable to each other in the longitudinal direction (left-right direction).

[0164] A plurality of second fixed parts 2 of different specifications, each having a different length of the cross section 21, may be prepared as the second fixed part 2. By replacing the second fixed part 2 with another second fixed part 2 of a different specification, the distance between the support parts 22 of each of the two second fixed parts 2 on both sides of the first fixed part 1 can be adjusted according to the length of the fixture (desk 7).

[0165] The wiring duct 3 is not limited to being fixed to the top plate 71 of the desk 7. The wiring duct 3 may be fixed to the side surface or the back surface of the top plate 71, for example.

[0166] The wiring duct 3 does not have to be attached to the fixture so that the longitudinal direction of the wiring duct 3 is along a horizontal plane, and may be attached to the fixture so that the longitudinal direction of the wiring duct 3 is along a vertical direction, for example. Also, for example, the wiring duct 3 may be incorporated into the side surface of the partition 6 that is along the up-down direction.

[0167] In the wiring duct 3, a plurality of storage sections 3110 that can be included in the mounting area may be provided and lined up in the longitudinal direction of the wiring duct 3.

[0168] Furthermore, the connector 95 is not limited to a plug, and may be a jack (receptacle). The wiring duct 3 may be capable of connecting both a first adapter to which a plug serving as the connector 95 can be connected, and a second adapter to which a jack serving as the connector 95 can be connected. This makes it possible to accommodate electrical devices 94 or cables equipped with either a plug or a jack. The first adapter and the second adapter may have a common configuration other than the portion connecting with the connector 95.

[0169] The wiring duct system 100 may be applied to, for example, a desk 7C (furniture) shown in Fig. 20. Specifically, the desk 7C is a desk that is assumed to be seated only at the front, and is called, for example, a counter desk. The furniture (desk 7C) includes a duct fixing device F2 that fixes the wiring duct 3. In other words, the desk 7C and the duct fixing device F2 are integrally formed.

[0170] The desk 7C includes a desk main body 70, a duct fixing device F2, and a back panel 74. The duct fixing device F2 has a first fixing portion 1C and two second fixing portions 2C. The desk main body 70 includes a top plate 701, a stand 702, and a support 703. A wiring duct 3 is attached to the desk 7C. A feed-in 4, an adapter 5, and a restricting member 8 (not shown in FIG. 20) are attached to the wiring duct 3.

[0171] The wiring duct system 100 is not limited to fixtures such as desks 7, 7C, but may also be applied to surfaces constituting the interior of buildings such as walls and ceilings, and walls of trains and other vehicles.

[0172] Although the wiring duct system 100 has been described in the embodiment as being direct current (DC), it may be alternating current. That is, the power received by the wiring duct system 100 and supplied to the connector 95 may be alternating current (AC). Therefore, the wiring duct system 100 may be either a DC wiring duct system or an AC wiring duct system.

[0173] Although the power supply system has been described as including the switching hub 92 and the splitter 93, the present invention is not limited to this. The power supply system may include, for example, an AC adapter 96 as shown in FIG. 21 instead of the switching hub 92 and the splitter 93. The AC adapter 96 converts the AC voltage supplied from the power source 91 into a voltage received by the wiring duct system 100, that is, a direct current (DC) voltage. Specifically, the AC adapter 96 may be configured to convert an AC voltage of 100V into a DC voltage of 24V.

[0174] Regarding the sockets in the adapter 5, in the above embodiment, the first socket 511 and the second socket 512 are sockets of different standards, but the first socket 511 and the second socket 512 may be sockets of the same standard. In addition, the number of sockets in the adapter 5 is not particularly limited, and may be, for example, one, or three or more.

[0175] (summary) As described above, the restricting member (8) according to the first aspect restricts removal of the adapter (5) from the wiring duct system (100). The wiring duct system (100) has a wiring duct (3) to which an adapter to be connected to a connector (95) is detachable, and supplies power to the connector (95) via the adapter (5). The restricting member (8) includes a flat plate-shaped portion (80) including an end surface portion (81) that contacts at least a portion of the adapter (5), and a switching portion (82) that switches between a locked state and an unlocked state by a switching key (K1). The restricting member (8) is attached to the wiring duct (3) in such a manner that the end surface portion (81) contacts at least the portion when the switching portion (82) is in the locked state. The plate thickness direction of the flat plate-shaped portion (80) is perpendicular to the mounting surface (502) of the adapter (5). The end surface portion (81) is formed along the plate thickness direction.

[0176] According to this embodiment, unless the switching unit (82) is unlocked by the switching key (K1), the restricting member (8) restricts removal of the adapter (5). As a result, the adapter (5) is less likely to be removed from the wiring duct (3).

[0177] In the restricting member (8) according to the second aspect, the plate thickness of the flat portion (80) in the first aspect is smaller than the thickness of the adapter (5) in the direction facing the mounting surface (502) of the adapter (5).

[0178] According to this embodiment, it is easy to make it difficult to take out and place the adapter 5 while maintaining the strength of the restricting member 8. In this case, it is also easy to contribute to reducing the size of the restricting member 8 and reducing the manufacturing cost.

[0179] The regulating member (8) of the third aspect, in the first or second aspect, has an end surface portion (81) which, in the locked state, has a first contact surface (811) that contacts a first circumferential surface (5101) of the adapter (5) that is aligned along the longitudinal direction of the wiring duct (3), and a second contact surface (812) that contacts a second circumferential surface (5102) of the adapter (5) that intersects with the first circumferential surface (5101) and intersects with one end of the first contact surface (811).

[0180] According to this embodiment, the adapter (5) can be fixed more firmly by the restricting member (8).

[0181] In the third aspect of the restricting member (8) according to the fourth aspect, the adapter (5) has a recess (55) on the mounting surface (502) that is closer to the mounting surface (501) of the connector (95) than the mounting surface (502). The flat portion (80) has a flat bent piece (8013) that intersects with the other end of the first contact surface (811) and is bent toward the opposite side to the first peripheral surface (5101) on the second peripheral surface (5102) side than the third peripheral surface (5103) that faces the second peripheral surface (5102). The tip of the flat bent piece (8013) is disposed between the recess (55) and the wiring duct (3) and is in contact with a surface that connects the mounting surface (502) and the recess (55).

[0182] According to this embodiment, a part of the restricting member (8) supporting the adapter (5) can be made invisible. Therefore, the appearance of the wiring duct system (100) is not excessively damaged. In this case, it is difficult for a user to insert his / her fingers between the adapter (5) and the duct rail (31), and the structure can be made to be more difficult to remove. Therefore, it is easy to provide a strong deterrent effect against taking out the adapter (5).

[0183] The regulating member (8) of the fifth aspect is the same as that of the third aspect, and further includes a third contact surface (813) in which the end surface portion (81) intersects with the first circumferential surface (5101), contacts a third circumferential surface (5103) of the adapter (5) opposite the second circumferential surface (5102), and intersects with the other end of the first contact surface (811).

[0184] According to this embodiment, removal of the adapter (5) can be more firmly restricted.

[0185] The restricting member (8) according to a sixth aspect is the restricting member (8) according to any one of the first to fifth aspects, in which the flat plate portion (80) and the switching portion (82) are integrally formed.

[0186] This embodiment can easily contribute to reducing the size of the restricting member (8) and the manufacturing costs.

[0187] Regarding the restricting member (8) according to the seventh aspect, in any one of the first to sixth aspects, the wiring duct (3) has a conductive bar (32) and a duct rail including a recessed storage section (3110) in which the conductive bar (32) is stored. The adapter (5) has a fixing rib (532), and the fixing rib (532) is inserted into the storage section (3110) and rotated a predetermined angle about a rotation axis along the insertion direction, thereby achieving electrical connection with the conductive bar (32) and preventing the conductive bar from being pulled out of the storage section (3110). When the switching section (82) is in the locked state, the restricting member (8) inhibits rotation of the adapter (5) by the end surface section (81).

[0188] According to this embodiment, even if an attempt is made to pull out the adapter (5), the housing (51) is surrounded by the end surface portion (81), which hinders rotation of the adapter (5), making it easier to restrict removal of the adapter (5).

[0189] In the seventh aspect of the restricting member (8) according to the eighth aspect, the adapter (5) has an operating portion (52) that is configured to be insertable and removable from the storage portion (3110) and limits rotation of the adapter (5) by inserting it into the storage portion (3110). The restricting member (8) has a flat portion (80) that covers the operating portion (52) so as to inhibit operation of the operating portion (52) when the switching portion (82) is in the locked state.

[0190] According to this embodiment, it is difficult for a person (user, etc.) to operate the operating portion 52 of the adapter 5 with the fingertips, etc. This makes it easier to restrict removal of the adapter 5.

[0191] Regarding the restricting member (8) according to the ninth aspect, in any one of the first to eighth aspects, the adapter (5) is attached to an arbitrary position within a longitudinally continuous attachment region of the wiring duct (3) and is movable along the longitudinal direction after attachment. When the switching portion (82) is in the locked state, the restricting member (8) is movable along the longitudinal direction integrally with the adapter (5).

[0192] According to this embodiment, it is possible to improve the convenience for the user who utilizes the power supply from the wiring duct system (100), while maintaining the restriction on removal of the adapter (5).

[0193] The restricting member (8) according to a tenth aspect is any one of the first to ninth aspects, in which the switching portion (82) has a cam portion (823) that fits into the wiring duct (3) in the locked state.

[0194] According to this embodiment, removal of the adapter (5) can be more firmly restricted.

[0195] The restricting member (8) according to an eleventh aspect is any one of the first to tenth aspects, wherein the switching portion (82) is configured to be switchable by a tool.

[0196] According to this aspect, the switching unit (82) is switched between locking and unlocking using a tool, making it more difficult for a person (such as a user) to easily remove the restricting member (8) and the adapter (5) and to take the adapter (5) away.

[0197] A wiring duct system (100) according to a twelfth aspect includes an adapter (5) to which a connector (95) is connected, a wiring duct (3) having a conductive bar (32) and a duct rail (31) including a recessed storage portion (3110) for storing the conductive bar (32), and the restricting member (8) according to any one of the first to eleventh aspects. The wiring duct system (100) supplies power to the connector (95) via the adapter (5).

[0198] According to this embodiment, the restricting member (8) having high strength makes it difficult for the adapter (5) to be removed from the wiring duct. [Explanation of symbols]
