[0041] (Implementation Method)

[0042] (summary)

[0043] First, the outline of the restriction member 8 according to the present embodiment, the adapter 5 to which the restriction member 8 is applied, and the duct system 100 will be described.

[0044] Figure 1 1 is a perspective view showing the restriction member 8 , the adapter 5 , and part of the duct system 100 , and more specifically, shows a state in which the restriction member 8 is attached to the adapter 5 in the duct system 100 .

[0045] Figure 2 1 is a perspective view showing a portion of the restricting member 8, the adapter 5, and the wiring duct system 100, and specifically shows a state where the restricting member 8 and the adapter 5 in the wiring duct system 100 are separated. Figure 1 and Figure 2As shown in the figure, the length direction of the wiring duct 3 when it is installed in the form of a normal object (such as daily appliances, etc.) is defined as the "left-right direction", the width direction as a direction orthogonal to the length direction is defined as the "up-down direction", and the depth direction orthogonal to both the length direction and the width direction is defined as the "front-back direction". However, the terms up-down, left-right, front-back are defined for the convenience of explanation and are not intended to limit the direction of use.

[0046] Figure 10 to Figure 13 1 is a diagram showing an application example of the wiring duct system 100. Fig.10 It is a stereogram. Fig.11 is the main view, Fig.12 This is the right side view. Fig.13 is a top view. Figure 10 to Figure 13 In the specification, the length direction of the wiring duct 3, which is usually set in the form of daily appliances, is defined as the "left-right direction", the width direction is defined as the "up-down direction", and the depth direction is defined as the "front-back direction", but the terms up-down, left-right, front-back are defined for the convenience of explanation, and the main purpose is not to limit the direction of use.

[0047] like Figure 1 As shown, the limiting member 8 of the present embodiment is constructed in a manner to limit the removal of the adapter 5 from the wiring duct system 100. Among them, the limiting member 8 is constructed in a manner to be placed externally on the adapter 5 in a state connected to the wiring duct system 100. The limiting member 8 includes a flat portion 80 and a switching portion 82. The flat portion 80 includes an end surface portion 81 that contacts at least a portion of the adapter 5. The switching portion 82 switches between a locked state and an unlocked state using a switching key K1. The limiting member 8 is installed on the wiring duct 3 in a manner in which the end surface portion 81 contacts at least a portion of the adapter when the switching portion 82 is in the locked state, thereby limiting the removal of the adapter 5. In addition, the plate thickness direction of the flat portion 80 is a direction orthogonal to the mounting surface 502 of the adapter 5. In addition, the end surface portion 81 is formed along the plate thickness direction. In addition, as Figure 1 and Figure 2 As shown, the plate thickness direction is consistent with the depth direction, that is, the front-back direction.

[0048] The wiring duct system 100 includes a wiring duct 3 to which an adapter 5 connected to a connector 95 can be detachably mounted. The wiring duct 3 includes a duct guide rail 31 (see Figure 1 , Figure 2 , Figure 5A , Figure 5B , Figure 6 etc.) and conductive rod 32 (refer to Figure 1 , Figure 2 , Figure 5A to Figure 8As an example, the conductive rod 32 can be electrically connected to the adapter 5 at any position in the installation area that is continuous in the length direction of the duct rail 31. In other words, the adapter 5 is installed at any position in the installation area that is continuous in the length direction of the wiring duct 3. The connector 95 (see Fig.18 ) 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 rod 32 is accommodated in the duct rail 31.

[0049] The installation area is an area provided on the surface or inside of the duct rail 31. The wiring duct 3 of this embodiment includes a recessed storage portion 3110 formed along the length direction of the duct rail 31 (see Figure 1 , Figure 2 ). In more detail, the recessed storage portion 3110 is formed across both ends in the length direction of the duct rail 31. The above-mentioned mounting area coincides with the area where the recessed storage portion 3110 is provided.

[0050] The connector 95 is a connector of the electrical device 94 (or a cable connected to the electrical device 94). By connecting the connector 95 to the adapter 5, power can be supplied from the wiring duct 3 to the electrical device 94. Therefore, compared with the case where power is supplied to the electrical device 94 from a power outlet or from a power tap that distributes power from the power outlet, it is easy to improve the wiring process.

[0051] The types of the electrical equipment 94 are not particularly limited. Examples of the electrical equipment 94 include computer terminals (personal computers, smartphones, tablet terminals, etc.), computer terminal accessories (monitors, speakers, microphones, etc.), lighting equipment (desk lamps, etc.), network cameras, sensors (temperature sensors, humidity sensors, illuminance sensors, etc.), game consoles, and air conditioning equipment (desk fans, etc.).

[0052] The wiring duct system 100 is used by being fixed to, for example, daily appliances. Daily appliances are a general term for appliances such as furniture and spare parts used in residential or non-residential areas. An example of a daily appliance is a table, a platform, and a workbench used as a table for placing items. Another example of a daily appliance is a shelf, a box, a dresser, a bed, a whiteboard, a shield, a partition, and a bench.

[0053] exist Figure 10 to Figure 17 In the above, as an example, the wiring duct system 100 is fixed to a table 7 as a daily appliance and used as an example. Fig.10 As shown in FIG. 1 , the table 7 has a top plate 71 that is rectangular in shape when viewed from above, two leg portions 72, and two support platforms 73. Fig.10 , there are cases where the direction along the long side of the top plate 71 is defined as the left-right direction, the direction along the short side of the top plate 71 is defined as the front-back direction, and the direction along the normal line of the top plate 71 is defined as the up-down direction. However, the purpose of these provisions is not to limit the use direction of the wiring duct system 100. In addition, Figure 1 , Figure 2 , Figure 4 , Figure 6 to Figure 17 The arrows indicating front, back, left, right, up and down in the figures are only indicated for explanation and do not actually exist.

[0054] As described above, the wiring duct system 100 is installed in daily appliances such as the table 7. That is, from the perspective of convenience, the adapter 5 can be installed at a position that is relatively easy to reach by a person, such as a user who uses the power from the wiring duct 3. In this case, there is a concern that the adapter 5 may be removed from the wiring duct 3 by a person (user, etc.) without authorization.

[0055] In contrast, Figure 1 and Figure 2 As shown, the limiting member 8 of this embodiment includes: a flat plate-shaped portion 80 including an end surface portion 81 covering at least a portion of the adapter 5; and a switching portion 82 that switches between a locked state and an unlocked state using a switching key K1. The limiting member 8 is mounted on the wiring duct 3 in a state where the end surface portion 81 covers at least a portion when the switching portion 82 is in the locked state, thereby limiting the removal of the adapter 5. In addition, as an example, it is assumed that the so-called "at least a portion" here is the operating portion 52 of the adapter 5 (see Figure 1 The operation unit 52 will be described in detail later.

[0056] According to this structure, as long as the switch portion 82 is not switched to the unlocked state by the switch key K1, the restricting member 8 restricts the removal of the adapter 5. As a result, it is difficult for the adapter 5 to be removed from the wiring duct 3. In addition, the plate thickness direction of the restricting member 8 of the present embodiment is a direction orthogonal to the mounting surface 502 of the adapter 5, and the end surface portion 81 is formed along the plate thickness direction, so that the strength of the restricting member 8 can be improved.

[0057] Therefore, according to the restriction member 8 of the present embodiment, it is possible to realize the restriction member 8 and the duct system 100 in which the adapter 5 is unlikely to be removed from the duct 3 and which have high strength.

[0058] (Details)

[0059] (1) Wiring duct system

[0060] Next, the wiring duct system 100 to which the restriction member 8 is applied and each structure that can be used in the wiring duct system 100 will be described in more detail.

[0061] The wiring duct system 100 includes an adapter 5, a wiring duct 3, and a limiting member 8. The wiring duct system 100 supplies power to the connector 95 via the adapter 5. In the present embodiment, the power supplied to the connector 95 by the wiring duct system 100 is direct current (DC) power. In the following description of the embodiment, unless otherwise specified, the case where the supplied power is direct current (DC) power will be described. However, as described in the following modified example, the power received by the wiring duct system 100 and supplied to the connector 95 may also be alternating current (AC) power.

[0062] like Fig.10 As shown, the wiring duct system 100 includes a duct fixing device F1, two wiring ducts 3 (in Fig.10 Only one is shown in the figure), two feed-in parts 4 (in Fig.10 Only one is shown in the figure), and two end caps E1 (in Fig.14 Only one is shown in the figure). The duct fixing device F1 has two first fixing parts 1 and two second fixing parts 2. The two first fixing parts 1 correspond to the two wiring ducts 3 in a one-to-one manner. Each first fixing part 1 holds the 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 the daily utensil (table 7).

[0063] In addition, as a structure used in the wiring duct system 100, there are one or more adapters 5 (see Figure 1 , Figure 2 ), 3 partitions 6, and a table 7.

[0064] (2) Table

[0065] like Fig.10 As shown, the table 7 has a top plate 71 that is rectangular in shape when viewed from above, two leg portions 72, and two support platforms 73. One of the two leg portions 72 protrudes downward from the vicinity of the right end of the top plate 71, and the other protrudes downward from the vicinity of the left end of the top plate 71. The two support platforms 73 correspond to the two leg portions 72 in a one-to-one manner. Each support platform 73 is connected to the lower end of the corresponding leg portion 72 to support the leg portion 72.

[0066] (3) First fixed part

[0067] like Fig.13 As shown, the two first fixing parts 1 are arranged front and back and matched with each other. Fig.14 As shown, the two first fixing parts 1 each include a tube housing portion 11 and two connecting protrusions 12. The tube housing portion 11 and the two connecting protrusions 12 are formed integrally.

[0068] The shape of the duct storage part 11 is a rectangular parallelepiped. The duct storage part 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 part 11, and the other protrudes from the left end of the duct storage part 11. The duct storage part 11 is used to store the wiring duct 3 (and the duct guide rail 31 of the wiring duct 3). In addition, the duct storage part 11 is also used to store the feed-in part 4. The two connecting protrusions 12 are structures for connecting the first fixing part 1 and the second fixing part 2.

[0069] Each first fixing portion 1 has a storage groove 130 and two wire-threading grooves 140. The storage groove 130 stores the wiring duct 3 and the feed-in portion 4. The wiring W1 (see Fig.16A , Fig. 16B ) passes through the wire threading groove 140.

[0070] The storage groove 130 is provided in the duct storage portion 11. The storage groove 130 is formed along the length direction (left-right direction) of the duct storage portion 11. In the first fixing portion 1 on the front side of the two first fixing portions 1, the storage groove 130 opens on the front surface of the duct storage portion 11, and in the first fixing portion 1 on the rear side, the storage groove 130 opens on the rear surface of the duct storage portion 11.

[0071] The two threading grooves 140 correspond to the two connecting protrusions 12 in a one-to-one manner. Each threading groove 140 is arranged across the corresponding connecting protrusion 12 and the pipe receiving portion 11. That is, the threading grooves 140 are respectively arranged at the right end and the left end of the first fixing portion 1. Each threading groove 140 is formed along the length direction (left-right direction) of the pipe receiving portion 11. In the first fixing portion 1 on the front side of the two first fixing portions 1, each threading groove 140 opens on the rear surface of the pipe receiving portion 11, and in the first fixing portion 1 on the rear side, each threading groove 140 opens on the front surface of the pipe receiving portion 11.

[0072] By matching the two first fixing parts 1, the threading grooves 140 at the right ends of the two first fixing parts 1 match each other to form a space (see Fig.16A ), and the threading grooves 140 at the left ends of the two first fixing parts 1 are matched to form another space. Each threading groove 140 is connected to the storage groove 130. The wiring W1 passing through the threading groove 140 is connected to the terminal part 432 (refer to Fig.16A , Fig. 16B ) is electrically connected to the conductive rod 32 of the wiring duct 3 (see Fig.15 , Fig.16A )Electrical connection.

[0073] The two first fixing parts 1 each have four recesses 150 (in Fig.14Only two are shown in the figure) as part of the partition fixing structure S1. Four pits 150 are provided in the pipe storage portion 11. By matching the two first fixing parts 1, the four pits 150 of each of the two first fixing parts 1 are matched respectively to form four gaps between the two first fixing parts 1. The four gaps correspond to the partition fixing structures S1 respectively. In more detail, each partition fixing structure S1 is a through hole that penetrates the structure formed by matching the two first fixing parts 1 in the up and down directions. The four partition fixing structures S1 are arranged in the left and right direction. Each partition 6 is fixed to the two first fixing parts 1 by inserting the mating protrusions protruding from the lower part thereof into the corresponding partition fixing structure S1.

[0074] (4) Second fixing part

[0075] like Fig.14 As shown, the two second fixing parts 2 respectively include a horizontal frame part 21, a support part 22, and a clamping mechanism 23. The horizontal frame part 21 and the support part 22 are formed integrally. The two second fixing parts 2 are fixing members for fixing the duct rail 31 to the daily utensil (here, the table 7). In more detail, the duct rail 31 is fixed to the table 7 by using the two second fixing parts 2 together with the two first fixing parts 1.

[0076] The shape of the horizontal frame portion 21 is a square tube. The axial direction of the horizontal frame portion 21 is along the left-right direction.

[0077] The two second fixing parts 2 correspond to the two connecting protrusions 12 of each of the two first fixing parts 1 in a one-to-one manner. The cross-frame part 21 of each second fixing part 2 is for the insertion of the corresponding connecting protrusions 12 of each of the two first fixing parts 1. Moreover, the two first fixing parts 1 are respectively screwed to the two second fixing parts 2. Thus, the two first fixing parts 1 are connected to the two second fixing parts 2. In other words, the two first fixing parts 1 are connected to the two second fixing parts 2 in a manner of being arranged between the two second fixing parts 2. In addition, the two first fixing parts 1 can be separated from the two second fixing parts 2 respectively. That is, by removing the screws connecting the two first fixing parts 1 and the two second fixing parts 2, each connecting protrusion 12 is pulled out from the cross-frame part 21, so that the two first fixing parts 1 can be separated from the two second fixing parts 2 respectively.

[0078] The support part 22 is cylindrical in shape. The axial direction of the support part 22 is along the vertical direction. The cross-frame part 21 protrudes from the upper end of the support part 22 in the left-right direction. The internal space of the cross-frame part 21 is connected to the internal space of the support part 22 to form an internal space SP1 (see Fig.14 ). Wiring W1 (refer to Fig.16A ) passes through the internal space SP1. That is, the second fixing portion 2 has a conductive rod 32 (see Fig.15 ) An internal space SP1 through which the electrically connected wiring W1 passes.

[0079] The support portion 22 has a wire insertion hole 220. The wire insertion hole 220 is provided on a side surface of the support portion 22. The wire W1 is led out from the internal space SP1 through the wire insertion hole 220 to the outside.

[0080] The clamp mechanism 23 is fixed to the table 7 by clamping the table 7. More specifically, one of the two second fixing parts 2 clamps the left end of the top plate 71 of the table 7, and the other clamps the right end of the top plate 71. Thus, the wiring duct system 100 is fixed to the table 7.

[0081] The clamp mechanism 23 includes a movable portion 231, a base 232, and a movable member operating portion 233 (see Fig.12 , Fig.14 ).

[0082] 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.

[0083] The movable portion 231 is disposed on the base 232 . A portion of the movable portion 231 is disposed inside the threading hole 220 of the support column 22 .

[0084] The movable member operating part 233 receives an operation for vertically moving the movable part 231. The movable member operating part 233 is a joystick, and the operator rotates the movable member operating part 233 to vertically move the movable part 231.

[0085] Next, the procedure for fixing the wiring duct system 100 to the table 7 using the clamping mechanism 23 will be described. Fig.11 As shown, the left end (or right end) of the top plate 71 of the table 7 is inserted into the threading hole 220. As a result, the left end (or right end) of the top plate 71 is arranged between the support column 22 and the movable portion 231. The operator rotates the movable member operating portion 233 to move the movable portion 231 upward. As a result, the left end (or right end) of the top plate 71 is clamped between the support column 22 and the movable portion 231. The left and right ends of the top plate 71 are clamped using the clamping mechanisms 23 of the two second fixing portions 2, so that the wiring duct system 100 is fixed to the table 7.

[0086] In addition, due to the presence of the support portion 22, a gap G1 is ensured between the two first fixing portions 1 of the wiring duct system 100 and the top plate 71 of the table 7 (see Fig.11). That is, a gap G1 is ensured between the two duct rails 31 fixed to the two first fixing parts 1 and the top plate 71. In other words, the second fixing part 2 includes a support part 22 that supports the two duct rails 31 with a gap G1 between the two duct rails 31 and the table 7. It is possible to transfer documents and other items in front of and behind the table 7 through the gap G1. In addition, an opening portion may be provided in a portion of the top plate 71 of the table 7 that is located below the first fixing part 1. The opening portion is a structure for leading out wiring for supplying AC power from under the top plate 71. The user can put his hand into the gap G1 and lead out the wiring through the opening portion.

[0087] (5) Wiring duct

[0088] The wiring duct 3 includes: a conductive rod 32; and a duct guide 31, which includes a concave storage portion 3110 for storing the conductive rod 32. The concave storage portion 3110 is sometimes referred to as "storage portion 3110" below. In this embodiment, as described above, the wiring duct system 100 includes two wiring ducts 3, such as Fig.14 , Fig.15 As shown, each wiring duct 3 has a duct rail 31 and two conductive bars 32. The duct rail 31 includes a first rail 311 and two second rails 312. Figure 1 , Figure 2 The wiring duct 3 shown can be equivalent to Fig.13 Any of the two wiring ducts 3 shown. Figure 1 , Figure 2 In the figure, the first fixing portion 1 is omitted.

[0089] The two wiring ducts 3 correspond to the two first fixing parts 1 in a one-to-one manner. Each wiring duct 3 is accommodated in the accommodation groove 130 of the corresponding first fixing part 1. Therefore, one of the two wiring ducts 3 is arranged on the front side relative to the partition 6, and the other is arranged on the rear side relative to the partition 6.

[0090] The two wiring ducts 3 are located on opposite sides to each other in a predetermined direction (front-rear direction) along a horizontal plane in a state where the plurality of wiring ducts 3 are fixed to the first fixing portion 1 and the second fixing portion 2 is fixed to the table 7 .

[0091] The first guide rail 311 is in the shape of a square tube. The first guide rail 311 is made of metal, for example. The axial direction (length direction) of the first guide rail 311 is along the left-right direction. The first guide rail 311 includes a storage portion 3110. The storage portion 3110 is formed along the length direction (left-right direction) of the duct guide rail 31. More specifically, the storage portion 3110 is formed across both ends of the length direction of the duct guide rail 31. Two conductive rods 32 are stored in the storage portion 3110.

[0092] The storage portion 3110 is opened along a direction perpendicular to the surface of the partition 6. That is, the storage portion 3110 is opened on a surface along the surface of the partition 6.

[0093] For example, Fig. 9 As shown, the first guide rail 311 further includes two engaging portions 3111 and two mounting grooves 3112 .

[0094] The two interlocking parts 3111 are grooves. The two interlocking parts 3111 are provided on the inner surface of the storage part 3110. The two interlocking parts 3111 are formed along the length direction (left-right direction) of the duct rail 31. In more detail, the two interlocking parts 3111 are formed across both ends of the length direction of the duct rail 31. The two interlocking parts 3111 are interlocked with the adapter 5. Thus, the adapter 5 is installed in the wiring duct 3. That is, the duct rail 31 includes an adapter mounting part (in other words, two interlocking parts 3111) for mounting the adapter 5. The steps for mounting the adapter 5 to the wiring duct 3 are discussed below.

[0095] The two mounting grooves 3112 are provided on the inner surface of the storage portion 3110. Of the two fitting portions 3111 and the two mounting grooves 3112, the two fitting portions 3111 are provided near the opening of the storage portion 3110. The two mounting grooves 3112 are formed along the length direction (left-right direction) of the duct rail 31. More specifically, the two mounting grooves 3112 are formed across both ends of the length direction of the duct rail 31.

[0096] The two mounting grooves 3112 correspond to the two second guide rails 312 in a one-to-one manner. The corresponding second guide rail 312 is embedded in each mounting groove 3112. Thus, the two second guide rails 312 are mounted on the first guide rail 311. The first guide rail 311 has two protrusions 3113 for preventing the two second guide rails 312 from falling off.

[0097] In addition, the first guide rail 311 further includes a limiting protrusion 3114. The limiting protrusion 3114 is a protrusion. Fig. 9 In the embodiment, the limiting protrusion 3114 is provided on the upper side of the first guide rail 311 in the vertical direction. The limiting protrusion 3114 can be inserted into the limiting recess 55 of the adapter 5 (see Figure 6 ).

[0098] The two second rails 312 each have a length in the left-right direction. The shape of the cross section of the second rail 312 perpendicular to the left-right direction is U-shaped. The second rail 312 has electrical insulation. The second rail 312 is formed of a synthetic resin material such as PVC (polyvinyl chloride). The second rail 312 holds the conductive rod 32 inside.

[0099] The two conductive rods 32 have lengths in the left-right direction. The two conductive rods 32 are respectively arranged from the right end to the left end of the pipeline guide rail 31. The two conductive rods 32 are connected to the corresponding wiring W1 (refer to Fig.15 One of the two conductive bars 32 of each wiring duct 3 is electrically connected to the positive-side wiring W1, and the other is electrically connected to the negative-side wiring W1. Thus, DC power is supplied to the two conductive bars 32.

[0100] (6) Feed-in section and end cap

[0101] like Fig.11 As shown, the two feed-in parts 4 correspond to the two wiring ducts 3 in a one-to-one manner. The two end caps E1 correspond to the two wiring ducts 3 in a one-to-one manner. The corresponding feed-in part 4 is installed at one of the first end and the second end in the length direction of each wiring duct 3, and the corresponding end cap E1 is installed at the other end.

[0102] The feed-in section 4 is used to connect the two conductive bars 32 of the wiring duct 3 to the corresponding wiring W1 (refer to Fig.15 ) is electrically connected. That is, the two conductive bars 32 are electrically connected to the corresponding wiring W1 via the feed-in section 4. Fig.15 , describing the structure of the feeding part 4.

[0103] The feeding portion 4 includes an outer box 41 , a terminal box 42 , and two terminal units 43 .

[0104] The outer box 41 has a rectangular parallelepiped shape and is used to house the terminal box 42 .

[0105] The terminal box 42 includes a first block 421 and a second block 422. The first block 421 and the second block 422 are combined to form the terminal box 42. The terminal box 42 is used to store two terminal units 43. In addition, the terminal box 42 includes two wire entry holes 423 for inserting two wirings W1. The two wire entry holes 423 are provided in the first block 421.

[0106] The two terminal units 43 each include a spring 431 and a terminal portion 432. The combination of the spring 431 and the terminal portion 432 constitutes a quick connection terminal. That is, the terminal unit 43 includes a quick connection terminal.

[0107] The spring 431 is formed by bending a metal plate, etc. The terminal portion 432 is formed of a metal plate and is formed in a plate shape. The terminal portion 432 is opposite to the spring 431. The two terminal units 43 correspond to the two conductive rods 32 in a one-to-one manner. The terminal portion 432 of each terminal unit 43 is electrically connected to the corresponding conductive rod 32.

[0108] like Fig.16A , Fig. 16BAs shown, the wire W1 inserted into the terminal box 42 through the wire entry hole 423 is sandwiched between the spring 431 and the terminal portion 432. Thus, the wire W1 is electrically connected to the terminal portion 432 and is held between the spring 431 and the terminal portion 432.

[0109] (7) Partition

[0110] In this embodiment, as described above, the wiring duct system 100 includes a partition fixing structure S1 that can fix the partition 6. "Partition" is also called a partition or a screen. Figure 7 to Figure 10 ) is provided with a wiring duct system 100 and a plurality of (here 3) partitions 6 (6A, 6B, 6C).

[0111] Each partition 6 is fixed above the top plate 71. Thus, the space above the top plate 71 is divided into a front space and a rear space. Some people (hereinafter referred to as "the first person") sit in front of the table 7, and some people (hereinafter referred to as "the second person") sit behind the table 7. The space between the first person and the second person is separated by the partition 6, so the possibility of droplet infection between the first person and the second person can be reduced.

[0112] Each partition 6 has, for example, light transmittance. 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-to-back direction. The planar shape of each partition 6 when viewed along the front-to-back direction is a rectangular shape. The mating protrusion of each partition 6 protrudes downward from the main body and is inserted into the through hole in the corresponding partition fixing structure S1. Thus, each partition 6 is fixed to the wiring duct system 100. That is, the partition fixing structure S1 is a structure that utilizes the dead weight of the partition 6 to fit the partition 6. In addition, by pulling out the mating 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 so that it can be detached.

[0113] (8) Adapter

[0114] like Fig.14 As shown, first fixing portions 1 are respectively arranged in front and behind the partition 6, and wiring ducts 3 are accommodated in each first fixing portion 1 (see Figure 7 ), the adapter 5 can be respectively attached and detached relative to the two wiring ducts 3. The wiring duct system 100 supplies power to the connector 95 via the adapter 5.

[0115] like Figure 1 , Figure 2 , Figures 4 to 9 As shown, the adapter 5 includes a housing 51, an operating portion 52, a mounting protrusion 53, two power receiving terminals 54, a spring accommodated in the housing 51, and a cover 56 (see Figure 5B , Figure 6 ). In addition, the adapter 5 also has a pair of connection connectors (such as USB ports) and a circuit substrate, etc., which are housed in the housing 51. Among them, the housing 51, the mounting protrusion 53, the two power receiving terminals 54, the pair of connection connectors, the circuit substrate, and the cover 56, etc. in the adapter 5 constitute the adapter body 50.

[0116] The housing 51 is made of, for example, resin. Figure 5A , Figure 5B as well as Figure 8 The cover 56 is assembled to the housing 51 by screwing, etc., in such a way that the open side of the housing 51 is blocked by the cover 56. The outer shape of the housing 51 is, for example, Figure 1 The shape of the housing 51 is a rectangular parallelepiped, but the present invention is not limited thereto. The outer shape of the housing 51 may be, for example, a cube, other polygonal prisms, a cylindrical shape, etc., as long as it does not deviate too much from the purpose of the present disclosure.

[0117] In this embodiment, the adapter 5 has a peripheral surface 510 in the adapter body 50 except for the connector mounting surface 501 on which the connector 95 is mounted and the mounting surface 502 including the cover 56. Figure 1 As shown, the peripheral surface 510 can also be said to be the surface constituting the four side surfaces of the housing 51 when the adapter 5 is viewed in the front-rear direction.

[0118] Among them, Figure 1 , Figure 2 , Figures 4 to 9 As shown in FIG. 1 , the peripheral surface 510 of the adapter 5 is described based on the posture of the adapter 5 in a state where the adapter 5 is connected to the wiring duct 3 and the rotation of the adapter 5 is restricted (hereinafter, also referred to as the "rotation restriction state"). However, the posture of the adapter 5 is not limited to this. In this case, the peripheral surface 510 of the adapter 5 is located on one side (in the longitudinal direction of the wiring duct 3). Figure 1 , Figure 2 , Figure 4 , Figure 5A , Figure 5B , Figure 8 , Fig. 9 When the circumferential surface (the lower direction in the up-down direction) is defined as the first circumferential surface 5101, a circumferential surface intersecting the first circumferential surface 5101 is defined as the second circumferential surface 5102, another circumferential surface intersecting the first circumferential surface 5101 (i.e., a surface different from the second circumferential surface 5102) is defined as the third circumferential surface 5103, and the circumferential surface intersecting both the second circumferential surface 5102 and the third circumferential surface 5103 is defined as the fourth circumferential surface 5104. That is, the adapter 5 has the first circumferential surface 5101, the second circumferential surface 5102, the third circumferential surface 5103, and the fourth circumferential surface 5104. In addition, as Figure 1 As shown, 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).

[0119] In addition, in the present disclosure, the state in which the rotation of the adapter 5 is released is sometimes referred to as the "rotation restriction release state" relative to the above-mentioned rotation restriction state. The rotation restriction release state can also include a state in which the adapter 5 is in the process of rotating. However, in the following description, the state in which the adapter 5 is rotated 90° counterclockwise from the rotation restriction state is mainly described as the rotation restriction release state. In the rotation restriction release state, each of the above-mentioned peripheral surfaces 510 reaches a position rotated 90° from the original position in the rotation restriction state. In addition, as discussed later, the state in which the adapter 5 is set in the wiring duct 3 and the restriction member 8 is not installed is sometimes simply referred to as the "configuration state" for description.

[0120] The housing 51 further includes a first insertion port 511 and a second insertion port 512. The first insertion port 511 is used as a connector 95 (see Fig.17 ) is an insertion port for a USB Type-A plug. The second insertion port 512 is an insertion port for a USB Type-C plug as the connector 95. That is, the standard of the first insertion port 511 is different from the standard of the second insertion port 512. The size of the first insertion port 511 is different from the size of the second insertion port 512. In the housing 51, a pair of connection connectors are mounted on the circuit substrate in a manner that they are one-to-one opposite to the first insertion port 511 and the second insertion port 512, respectively. The connector 95 inserted into the first insertion port 511 or the second insertion port 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 substrate.

[0121] The first insertion port 511 and the second insertion port 512 are provided on the surface (connector mounting surface 501) facing the opposite side to the wiring duct 3 when the adapter 5 is mounted on the wiring duct 3. Figure 1 is the front surface). Figure 1 , Figure 2 , Figure 5A as well as Figure 8 As shown, the first insertion port 511 and the second insertion port 512 are arranged vertically when the adapter 5 is attached to the wiring duct 3 .

[0122] The operating portion 52 is configured to be pluggable relative to the storage portion 3110, and is configured to restrict the rotation of the adapter 5 by being inserted into the storage portion 3110. The operating portion 52 is held by the housing 51. The operating portion 52 is made of, for example, resin. The operating portion 52 is plate-shaped. The operating portion 52 has a grip portion 521, and the operating portion 52 is held by the housing 51 in a state where the grip portion 521 is exposed from one side of the housing 51. Specifically, the grip portion 521 is on one of the circumferential surfaces 510 of the housing 51 (for example, on the side of the housing 51). Figure 1 In the figure, it is a groove portion 522 arranged in a part of the second peripheral surface 5102) provided in the peripheral surface. The groove portion 522 is formed into a concave shape in the peripheral surface in a manner that is closed in the front direction, open in the rear direction, and one level lower than the peripheral surface. The operating portion 52 is arranged in a manner that the grip portion 521 can move in the front-to-back direction. Normally, the grip portion 521 is maintained so as to be accommodated in the groove portion 522 in the peripheral surface when it is not in a rotationally restricted state. That is, by applying force to the grip portion 521 with a person's fingertips, etc., the operating portion 52 can be moved in a predetermined direction (in a predetermined direction). Fig.14 The operating portion 52 slides and moves in the shell body 51 (in the front-to-back direction). The operating portion 52 is held in the shell body 51 in a state in which the restoring force of the spring housed in the shell body 51 acts on the operating portion 52 in the direction (rearward) in which the operating portion 52 is away from the connector assembly surface 501. Therefore, when no force is applied to the operating portion 52, the claw portion 520 located at the top end of the operating portion 52 is in a state of protruding from the shell body 51 to the side opposite to the connector assembly surface 501. By using a person's fingertips or the like to overcome the force of the spring and apply a force to the grip portion 521 forward, the operating portion 52 moves to the front side in the front-to-back direction. In the above-mentioned rotation restriction state, the operating portion 52 is located on one side in the left-right direction (in the rear side). Figure 1 In the rotation restriction released state, the operation portion 52 is located in a direction other than the left-right direction (for example, Figure 2 The middle is the lower side in the up-down direction).

[0123] The cover 56 is made of resin, for example. The cover 56 is in the shape of a rectangular plate. A mounting protrusion 53 is provided on the rear surface of the cover 56. Figure 5B , Figure 6 As shown, the cover 56 is formed as a continuous whole with the mounting protrusion 53. 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 to the connector mounting surface 501. The two fixing ribs 532 protrude from the side of the shaft portion 531. The two fixing ribs 532 protrude in opposite directions to each other.

[0124] The two power receiving terminals 54 protrude from the housing 51 to the side opposite to the connector mounting surface 501. The top end of each of the two power receiving terminals 54 is bent. The two power receiving terminals 54 are held by the mounting protrusion 53 in such a manner that their bent top ends are exposed from the top end of the shaft portion 531 (see Figure 6 ).

[0125] The adapter 5 has a recessed portion (hereinafter also referred to as a "restricting recessed portion 55" (see Figure 5B Specifically, the limiting recess 55 is formed by a recess formed on the rear end surface of the housing 51 and the surface of the cover 56. Figure 5B , Figure 6 As shown, the restricting recessed portion 55 includes a first recessed portion 551 and a second recessed portion 552 .

[0126] The first recess 551 is formed by lowering a portion of the end surface of the housing 51 on the rear side in the front-to-back direction toward the connector mounting surface 501. Figure 5B , Figure 6 In the figure, the region of the first recess 551 is indicated by darker dotted shadows for easier understanding.

[0127] The second recess 552 is formed by lowering a portion of the surface of the cover 56 located on the rear side in the front-rear direction toward the connector mounting surface 501. Figure 5B , Figure 6 In the figure, the area of ​​the second recess 552 is indicated by a lighter dotted shadow for easy understanding. The bottom surface of the first recess 551 is substantially flush with the bottom surface of the second recess 552. Thus, the first recess 551 is included in the housing 51, and the second recess 552 is included in the cover 56.

[0128] When the adapter 5 is mounted on the duct rail 31, the limiting protrusion 3114 (see Figure 4 ) is inserted into the limiting recess 55. If the orientation of the adapter 5 is the wrong orientation, for example Figure 6 The adapter 5 shown is oriented upside down, so the limiting protrusion 3114 interferes with the area of ​​the rear surface of the adapter 5 that protrudes one level relative to the limiting recess 55, and thus the adapter 5 cannot be mounted on the duct rail 31. That is, the limiting recess 55 and the limiting protrusion 3114 limit the orientation of the adapter 5 when the adapter 5 is mounted on the duct rail 31.

[0129] The mounting surface 502 is the surface of the wiring duct system 100 that is opposite to the wiring duct 3 when the adapter 5 is mounted. Figure 6 As shown in FIG. 1 , the mounting surface 502 can also be said to be the back surface on the rear side in the front-to-rear direction when it is arranged in the wiring duct 3. In other words, in the adapter 5, the mounting surface 502 can be said to be the surface on the front side in the front-to-rear direction, that is, the surface on the opposite side of the connector mounting surface 501. In addition, Figure 6 The figure shown in the frame in FIG. 1 is a rear view showing a part of the back side of the connector 95 in the state where the rotation restriction is released. Figure 6 In the figure shown in the lead frame, the wiring duct 3 is shown with a two-dot chain line for the sake of perspective for convenience.

[0130] The mounting surface 502 includes the cover 56 and may also include elements constituting the cover 56. In addition, the mounting surface 502 may include the peripheral end of the rear side of the housing 51 in the front-to-back direction. The first recess 551 described above is included in the peripheral end of the rear side of the housing 51 in the front-to-back direction. Therefore, the mounting surface 502 may have a surface where the entire surface of the mounting surface 502 does not contact the wiring duct 3 when the adapter 5 is arranged. Specifically, for example, Figure 5B , Figure 6 As shown, the portion where the restricting recess 55 formed at a position one level lower than the cover 56 of the mounting surface 502 is located does not directly contact the wiring duct 3 , and thus a gap is provided between the adapter 5 and the wiring duct 3 .

[0131] The adapter 5 also has a power converter (not shown). A plurality of electronic components constituting the power converter are mounted on a circuit board in the housing 51. The power converter converts the power received by 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 connection connectors (USB ports). Fig.17 ) can be connected to the first insertion port 511 or the second insertion port 512 by means of a connector 95 (see Fig.18 ) cable to receive power.

[0132] Next, a procedure for attaching the adapter 5 to the wiring duct 3 will be described.

[0133] As mentioned above, the adapter 5 has the fixing ribs 532. Figures 4 to 6 , Fig. 9 In the rotation restriction state, the two fixing ribs 532 are arranged in the vertical direction. In addition, in the rotation restriction release state, the two fixing ribs 532 are arranged in the left-right direction.

[0134] First, if Figure 6 , Figure 7 As shown, the operator holds the adapter 5 in a manner such that the direction in which the two fixing ribs 532 are arranged is along the length direction (left-right direction) of the duct rail 31. In this state, the surface of the grip portion 521 of the operating portion 52 faces downward in the vertical direction (refer to Figure 6 , Figure 7). In this state, the two fixing ribs 532 do not interfere with the duct rail 31, and the mounting protrusion 53 can be inserted into the receiving portion 3110 of the duct rail 31 along the insertion direction A1 (rearward). At this time, the claw portion 520 at the top of the operating portion 52 contacts the first fixing portion 1, and due to the contact pressure of the first fixing portion 1, the operating portion 52 moves toward the connector assembly surface 501 side (front).

[0135] In such Figure 6 , Figure 7 After inserting the mounting protrusion 53 into the housing portion 3110 as shown, the operator rotates the adapter 5 90 degrees clockwise around the rotation axis B1. Figure 6 , Figure 7 The rotation axis B1 shown is an imaginary axis and is substantially consistent with the central axis of the shaft portion 531. Fig. 9 As shown, the two fixing ribs 532 are inserted into the two fitting parts 3111. Thus, the front-to-back movement of the adapter 5 is restricted. Fig. 9 As shown, the rotation of the adapter 5 is restricted by inserting the operating portion 52, more specifically, the claw portion 520 of the operating portion 52 into the storage portion 3110 of the duct rail 31. In addition, the two power receiving terminals 54 are respectively in contact with the corresponding conductive rods 32, thereby being electrically connected to the corresponding conductive rods 32. In short, the adapter 5 is electrically connected to the conductive rod 32 by inserting its fixing rib 532 into the storage portion 3110 and rotating the adapter 5 by a predetermined angle (for example, 90 degrees) around the rotation axis B1 along the insertion direction A1, and the adapter 5 can be prevented from being pulled out of the storage portion 3110.

[0136] According to the above steps, the adapter 5 is mounted on the wiring duct 3. The adapter 5 can be mounted on the wiring duct 3 at any position in the region where the storage portion 3110 is provided (the mounting region continuous in the longitudinal direction of the wiring duct 3). In addition, the adapter 5 can be electrically connected to the conductive rod 32.

[0137] In the present embodiment, the adapter 5 is not provided with a structure for restricting the left-right movement of the adapter 5 mounted on the wiring duct 3. Therefore, the adapter 5 can move in the left-right direction in the state of being mounted on the wiring duct 3. In other words, the adapter 5 can move along the length direction of the wiring duct 3 after being mounted. However, in order to suppress the 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 structure for restricting the left-right movement of the adapter 5 mounted on the wiring duct 3. In addition, the above-mentioned movement includes, for example, a sliding movement in which the position of the adapter 5 in the up-down direction is not changed and the position in the left-right direction is only changed by sliding.

[0138] Next, the procedure for removing the adapter 5 from the wiring duct 3 is described. For the adapter 5 in the configured state, if the operator applies a force to the grip portion 521 of the operating portion 52 toward the connector mounting surface 501 side, the operating portion 52 can also move toward the connector mounting surface 501 side, thereby the claw portion 520 is separated from the storage portion 3110. In this way, the restriction on the rotation of the adapter 5 is released. When the operator rotates the adapter 5 counterclockwise by 90 degrees, the two fixing ribs 532 are separated from the two fitting portions 3111. Then, the adapter 5 is removed from the wiring duct 3 by pulling it out toward the front (for example, the front side in the front-to-back direction).

[0139] (9) Power supply system

[0140] Next, refer to Fig.18 , an example of the structure of a system (including a wiring duct system 100) for supplying electric power to an electrical device 94 will be described.

[0141] A switching hub 92 and a splitter 93 are installed in a facility at a place where an electric 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.

[0142] The switching hub 92 is a PoE switching hub corresponding to PoE (Power over Ethernet). The switching hub 92 is electrically connected to the separator 93 via a LAN (Local Area Network) cable. In addition, the switching hub 92 can also be electrically connected to devices corresponding to PoE. Devices corresponding to PoE are, for example, computer terminals, network cameras, IP (Internet Protocol) phones, and wireless access points. The switching hub 92 can exchange PoE signals having data and power (DC power) between devices electrically connected to the switching hub 92.

[0143] The splitter 93 is a PoE splitter corresponding to 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 not corresponding to PoE. As an example, the splitter 93 supplies the power separated from the PoE signal to one or more electrical devices 94 not corresponding to PoE via the wiring duct system 100.

[0144] In addition, the separator 93 transmits a data signal including data separated from the PoE signal to a device not compatible with PoE.

[0145] The DC power output terminal of the separator 93 is electrically connected to the first end of each of the four wiring lines W1. One of the two wiring ducts 3 corresponds to two of the four wiring lines W1, and the other wiring duct 3 corresponds to the remaining two wiring lines W1. The following description focuses on one wiring duct 3, the two wiring lines W1 corresponding to the wiring duct 3, and one feeder 4.

[0146] The two wirings W1 are the wiring on the positive side and the wiring on the negative side. The two wirings W1 are connected to the two wire entry holes 423 (see Fig.15 ). In addition, the two wirings W1 correspond to the two conductive rods 32 of the wiring duct 3 in a one-to-one manner. The second ends of the two wirings W1 are respectively inserted into the corresponding wire entry holes 423 and electrically connected to the corresponding conductive rods 32. One or more adapters 5 can be connected to the wiring duct 3, and one or more electrical devices 94 can be electrically connected to each conductive rod 32 via the adapters 5.

[0147] As described above, each electrical device 94 can receive power supplied from the wiring W1 via the conductive rod 32 and the adapter 5. Fig.10 ) or around table 7.

[0148] The DC voltage (voltage between the two conductive bars 32) received by the adapter 5 from the two conductive bars 32 is preferably 60 V or less. In this case, there is an advantage that no qualification of electrician or the like is required when installing the adapter 5. Therefore, compared with the case of relocating or newly installing an AC 100V socket, it is easier to ensure power supply.

[0149] The DC voltage received by the adapter 5 from the two conductive bars 32 is preferably 24 V or less. In addition, the DC voltage received by the adapter 5 from the two conductive bars 32 is also preferably 48 V or less.

[0150] As an example, the DC voltage of the PoE signal output from the switching hub 92 is 48 V. The separator 93 has a function of stepping down the DC voltage of the PoE signal received from the switching hub 92. As an example, the DC voltage output from the separator 93 is 24 V. The adapter 5 receives the DC voltage output from the separator 93 and outputs a DC voltage of 24 V or less to the electrical device 94.

[0151] By setting the voltage between the two conductive rods 32 of the wiring duct 3 to 60V or less (for example, 24V), the possibility of electric shock when the user touches the conductive rods 32 can be reduced. Therefore, it is not necessary to provide a cover on the wiring duct 3, which has the following advantages: the labor and time of installing and removing the cover are not required when installing the adapter 5 to the wiring duct 3.

[0152] In the above, an example of the configuration of the system for supplying electric power to the electric device 94 has been described. However, instead of this system, for example, each wire W1 may be connected to a socket of a commercial power source via an AC adapter in a simpler manner.

[0153] (10) Restriction member

[0154] In the present embodiment, in the wiring duct system 100, as described above, the restricting member 8 includes the flat plate portion 80 and the switching portion 82. In the wiring duct system 100, the end surface portion 81 of the restricting member 8 contacts at least a portion of the adapter 5. Figure 1 , Figure 5A , Figure 6 As shown in FIGS. 8A and 8B , the end surface portion 81 of the flat plate-shaped portion 80 of the restricting member 8 contacts a part of the operating portion 52 of the adapter 5 .

[0155] The limiting member 8 is made of, for example, a metal plate. There is no particular limitation on the method for making the limiting member 8. For example, the limiting member 8 can be made by punching a metal plate into a shape having an appropriate structure, and the flat plate-shaped portion 80 and the switching portion 82 having the end surface portion 81 can be made separately, or the limiting member 8 can be made by combining the flat plate-shaped portion 80 and the switching portion 82. In addition, the limiting member 8 can also be made integrally with the flat plate-shaped portion 80 and the switching portion 82. In addition, the material of the limiting member 8 is not limited to metal, and can also be made of thermoplastic resin such as plastic, thermosetting resin, etc.

[0156] like Figure 3A to Figure 3D As shown in FIG. 1 , the flat plate portion 80 is composed of a flat plate. Specifically, the flat plate portion 80 is a substantially flat plate-shaped member having a relatively thin thickness relative to the length in the longitudinal direction. The thickness referred to here refers to the thickness in the plate thickness direction, which is a direction orthogonal to the mounting surface 502 of the adapter 5. That is, Figure 1 As shown, the plate thickness direction of the flat plate-shaped portion 80 of the present embodiment is the depth direction (front-back direction) which is one direction orthogonal to the length direction (left-right direction) of the wiring duct 3. The plate thickness of the flat plate-shaped portion 80 is smaller than the thickness of the adapter 5 in the direction toward 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 maintain the strength of the restricting member 8, and it is not easy to remove the adapter 5. In addition, in this case, it is also easy to contribute to the miniaturization of the restricting member 8 (for example, space saving in the thickness direction) and the reduction of manufacturing costs.

[0157] The flat plate portion 80 has a flat plate front portion 801 facing the front side in the depth direction (front side in the front-rear direction) and a flat plate back portion 802 facing the back side in the depth direction (rear side in the front-rear direction). The flat plate front portion 801 and the flat plate back portion 802 are connected via the end surface portion 81.

[0158] The flat plate-shaped portion 80 includes an end surface portion 81 that covers at least a portion of the adapter 5. The end surface portion 81 is not located on the front and back surfaces of the flat plate-shaped portion 80, that is, the flat plate front surface portion 801 and the flat plate back surface portion 802, but is located on a surface that constitutes a portion of the surface that forms the thickness of the flat plate-shaped portion 80. In the present embodiment, the plate thickness direction of the flat plate-shaped portion 80 is a direction orthogonal to the mounting surface 502 of the adapter 5 mounted in the wiring duct system 100. That is, the end surface portion 81 is formed along the plate thickness direction. Therefore, in the present embodiment, the plate thickness portion constituting the end surface portion 81 is in contact with at least a portion of the peripheral surface 510 of the adapter 5.

[0159] The end surface portion 81 can function to restrict the left-right movement of the adapter 5. Specifically, the end surface portion 81 includes a contact surface 810 that contacts at least a portion of the peripheral surface 510 of the adapter 5 in the rotation restriction state of the adapter 5 or the locked state or released state of the switch portion 82. The contact surface 810 can be a surface that contacts the peripheral surface 510 of the adapter 5 in a one-to-one correspondence in the rotation restriction state of the adapter 5.

[0160] In the present embodiment, the flat plate portion 80 can restrict the removal of the adapter 5 by contacting the operating portion 52 which is at least a part of the adapter 5, but the end surface portion 81 has one or more contact surfaces 810 that contact the peripheral surface 510 of the adapter 5, so that the removal of the adapter 5 can be more firmly restricted. In the present embodiment, the end surface portion 81 includes three contact surfaces 810 (811, 812, 813).

[0161] Here, as described in the description of the adapter (8) above, the contact surface 810 of the limiting member 8 is described based on the posture of the adapter 5 in the rotation limiting state. In addition, the rotation limiting state also includes the case of any state of the locked state and the unlocked state. The reason is that the so-called rotation limiting state here only refers to whether the rotation of the adapter 5 is limited regardless of the limiting member 8.

[0162] 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. The first contact surface 811 can contact at least a portion of the first peripheral surface 5101 in the rotation restricted state and hold the adapter 5. The second contact surface 812 is a surface that contacts the second peripheral surface 5102 of the adapter 5. The second contact surface 812 can contact at least a portion of the second peripheral surface 5102 in the rotation restricted state and hold the adapter 5. Therefore, the adapter 5 can be fixed more firmly by the restriction member 8. In addition, in this case, a portion of the second contact surface 812 can also contact the operating portion 52 in the adapter 5. The third contact surface 813 is a surface that contacts the end surface 550 in the restriction recess 55 in the present embodiment. Specifically, the end surface 550 is a boundary surface (end surface 550) in the front-to-back direction between the second recess 552 formed by lowering a portion of the surface of the cover 56 located on the rear side in the front-to-back direction by one step toward the connector mounting surface 501 and a portion 561 that is raised one step higher than the second recess 552 toward the connector mounting surface 501. The third contact surface 813 enters the limiting recess 55 and contacts at least a portion of the end surface 550 to hold the adapter 5. Therefore, in the present embodiment, the third contact surface 813 does not contact the third peripheral surface 5103 of the adapter 5.

[0163] The flat plate portion 80 has a flat plate longitudinal piece 8011, a flat plate transverse piece 8012, and a flat plate bent piece 8013. The flat plate longitudinal piece 8011, the flat plate transverse piece 8012, and the flat plate bent piece 8013 are formed integrally. The flat plate longitudinal piece 8011 is a piece extending in the width direction (up and down direction), one end of which is connected to the flat plate transverse piece 8012. The flat plate transverse piece 8012 is a piece extending in the length direction (left and right direction), one end of which is connected to the flat plate longitudinal piece 8011, and the other end of which is connected to the flat plate bent piece 8013. The flat plate bent piece 8013 is a piece extending in the up and down direction, one end of which is connected to the flat plate transverse piece 8012. The flat plate longitudinal piece 8011 and the flat plate transverse piece 8012 are configured in a substantially orthogonal manner, and the flat plate transverse piece 8012 and the flat plate bent piece 8013 are configured in a substantially orthogonal manner. In addition, the flat plate-shaped vertical piece 8011 is substantially parallel to the flat plate-shaped bent piece 8013. In this embodiment, when the adapter 5 is in the rotation restricted state, the top end of the flat plate-shaped bent piece 8013 is disposed between the restriction recess 55 of the adapter 5 and the wiring duct 3, and contacts the surface of the connection mounting surface 502 and the restriction recess 55.

[0164] The flat plate portion 80 is a plate-like shape that is substantially U-shaped when viewed from the front when the limiting member 8 is mounted. In the present embodiment, the width direction length of the flat plate-shaped bent piece 8013 is formed shorter than the width direction length of the flat plate-shaped vertical piece 8011. The flat plate-shaped portion 80 is configured to be in contact with both side surfaces in the longitudinal direction of the housing 51 of the adapter 5 with substantially no gap when the limiting member 8 is mounted, or with a slight gap.

[0165] A switching portion 82 is formed on a portion of the flat plate-like vertical piece 8011. Figure 1 In the above, the switching portion 82 is formed at a portion of the flat plate-like vertical piece 8011 on the upper side in the up-down direction.

[0166] One end surface of the flat horizontal piece 8012 can become the first contact surface 811 , one end surface of the flat vertical piece 8011 can become the second contact surface 812 , and one end surface of the flat bent piece 8013 can become the third contact surface 813 .

[0167] The switching portion 82 includes a head portion 820, a switching shaft portion 822, and a cam portion 823. Specifically, for example, the flat plate-shaped vertical piece 8011 of the flat plate-shaped portion 80 has a through hole (not shown) penetrating the flat plate-shaped vertical piece 8011 from the surface of the flat plate-shaped vertical piece 8011 toward the back surface, and the switching portion 82 includes: the switching shaft portion 822, which passes through the through hole; and the cam portion 823, which is located at a position on the side opposite to the top end of the switching shaft portion 822 and can be engaged for switching between locking and unlocking.

[0168] A key hole portion 821 is formed at the head portion 820 located at the top end of the switching shaft portion 822. For example, the head portion 820 is formed with a screw head-shaped key hole portion 821. In this embodiment, as in Figure 1 As shown in the figure, the head 820 has a cross-shaped keyhole portion 821. In this case, the switching portion 82 can be switched using a tool such as a cross screwdriver having a shape based on the shape of the keyhole. That is, the switching portion 82 is configured so that the switching operation can be performed using a tool. The head 820 is configured to have a diameter or size larger than the outer diameter of the switching shaft portion 822.

[0169] The switching shaft portion 822 is formed along a direction orthogonal to the flat plate front portion 801 and the flat plate rear portion 802 of the flat plate-shaped portion 80 .

[0170] The cam portion 823 is formed in a flat plate shape. The cam portion 823 is fixed to the top end 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 about the same as the plate thickness of the flat plate portion 80. The cam portion 823 is provided separately from the flat plate back portion 802, that is, a gap is provided between the cam portion 823 and the flat plate back portion 802.

[0171] In the wiring duct system 100, when the restricting member 8 is installed, as described above, the restricting member 8 covers at least a portion of the adapter 5. Among them, the restricting member 8 can restrict the removal of the adapter 5 by covering the operating portion 52, which is at least a portion of the adapter 5, with the second contact surface 812 of the end surface portion 81. In addition, in the present embodiment, a portion of the first contact surface 811 also covers at least a portion of the first peripheral surface 5101 of the adapter 5. In addition, a portion of the second contact surface 812 covers at least a portion of the second peripheral surface 5102 of the adapter 5. Moreover, a portion of the third contact surface 813 contacts at least a portion of the mounting surface 502 in the restricting recess 55 of the adapter 5. Thus, the adapter 5 is covered with a portion of the peripheral surface of the adapter 5 by the restricting member 8. Therefore, the removal of the adapter 5 can be more firmly restricted. In the present embodiment, in the restricting member 8, the flat plate-shaped bent piece 8013 having the third contact surface 813 is accommodated between the third peripheral surface 5103 and the end surface 550 in the restricting recess 55. That is, the top end of the flat bent piece 8013 is arranged between the limiting recess 55 and the wiring duct 3, and contacts the surface connecting the mounting surface 502 and the limiting recess 55. Thus, it is possible to avoid visually recognizing a portion of the limiting member 8 supporting the adapter 5. Therefore, it is possible to prevent the appearance of the wiring duct system 100 from being excessively damaged. In addition, in this case, it is possible to set a structure that is difficult for the user's fingers to be inserted between the adapter 5 and the duct guide 31 and is even more difficult to disassemble. Therefore, it is easy to exert a high restraining force against the adapter 5 being taken away. In addition, in the above content, a case where a portion of the limiting member cannot be visually recognized in the locked state is described, but it is also possible that a portion of the limiting member cannot be visually recognized in the unlocked state. For example, even if it is not in the locked state, a portion of the limiting member 8, such as the flat bent piece 8013, is also hidden.

[0172] The restriction member 8 can restrict the adapter 5 from being removed from the wiring duct system 100 based on the flat plate portion 80 and the switching portion 82 of the restriction member 8 and the switching key K1. A lock system using the restriction member 8 of this embodiment will be described below.

[0173] (11) Locking system

[0174] Below, while referring to Figure 1 to Figure 6 A system for operating a locked state and an unlocked state using the restriction member 8 of the present embodiment (referred to as a “lock system” in the present disclosure) will be described in detail.

[0175] like Figure 1As shown, the lock system includes a restriction member 8 and a switching key K1. As described above, the restriction member 8 is a member that restricts the removal of the adapter 5 from the wiring duct system 100. The restriction member 8 includes a flat plate portion 80 and a switching portion 82. As an example, the flat plate portion 80 and the switching portion 82 are formed integrally.

[0176] The following, such as Figure 1 As shown, the state in which the restriction member 8 is attached to the duct system 100 and the removal of the adapter 5 is restricted may be simply referred to as “when the restriction member 8 is used”.

[0177] The switching key K1 is a member for performing a switching operation on the switching portion 82 of the limiting member 8. For the switching key K1, for example, in a case where the head portion 820 in the switching portion 82 has a keyhole portion 821, specifically, in a case where the head portion 820 is formed with a keyhole, as an example, the switching key K1 is a round key (a so-called tubular key (Japanese: エースキー)). By inserting the switching key K1 into the keyhole portion 821 of the switching portion 82 and rotating the switching key K1, the state of the switching portion 82 is switched from an unlocked state to an upwardly locked state, or from a locked state to an unlocked state. The type of the switching key K1 is not particularly limited, and it may also be a disc cylinder key, etc. In addition, the switching key K1 may also have a spare key.

[0178] In the present embodiment, in the switching portion 82, as an example, the head portion 820 has a cross-shaped keyhole portion 821. In this case, the switching key K1 can be a tool such as a cross screwdriver. Therefore, as the switching key K1 for operating the switching portion 82, a tool corresponding to the shape of the switching portion 82 can be used. That is, the switching portion 82 is configured in a manner that a switching operation can be performed using a tool. Therefore, the switching of the locking and unlocking of the switching portion 82 is performed using a tool, so that it is more difficult for a person (user, etc.) to easily perform the operation of disassembling the limiting member 8 and the adapter 5. In addition, the tool that can serve as the switching key K1 is not limited to the cross screwdriver described above, and can be appropriately changed according to the structure of the switching portion 82 of the limiting member 8.

[0179] Next, the procedure for using the restriction member 8 in the lock system will be described.

[0180] First, the operator installs the adapter 5 on the wiring duct 3. Next, the operator holds the restricting member 8 and covers the adapter 5 from the lower side in the vertical direction so that the end surface 81 of the flat plate portion 80 of the restricting member 8 contacts at least a part of the peripheral surface 510 of the adapter 5 (see Figure 1 and Figure 2 wait).

[0181] When the switch 82 is in the unlocked state, Figure 2 and Figure 3A to Figure 3D As shown, the long axis of the cam portion 823 is in a state along the length direction (left-right direction) of the duct rail 31. In addition, before the restricting member 8 is provided, the cam portion 823 is also in a state other than the state in which the long axis is in the width direction (up-down direction) of the duct rail 31. Therefore, in the unlocked state, the cam portion 823 can be inserted into the storage portion 3110 of the wiring duct 3 along the insertion direction A1 in a state in which the end surface portion 81 of the flat portion 80 surrounds the adapter 5.

[0182] Then, the operator inserts the switching key K1 into the key hole 821 and rotates it clockwise, for example. Figure 1 , Figure 3B , Figure 3C As shown, the cam portion 823 connected to the switching shaft portion 822 rotates so that the long axis of the cam portion 823 is along a direction (up and down direction) orthogonal to the length direction of the duct guide rail 31, and the switching portion 82 is switched from the unlocked state to the locked state. Figure 4 As shown, the cam portion 823 is engaged with the two engaging portions 3111 of the first guide rail 311 in the wiring duct 3. In other words, the engaging targets of the two fixing ribs 532 of the adapter 5, namely the engaging portions 3111, are used as the engaging targets of the cam portion 823. In the locked state, the limiting member 8 is in a state where the end surface portion 81 contacts a part of the peripheral surface 510 of the adapter 5, and cannot be pulled out from the storage portion 3110 of the wiring duct 3. Specifically, in the locked state, the limiting member 8 is in a state where the end surface portion 81 contacts a part of the peripheral surface 510 of the adapter 5, and cannot be pulled out from the storage portion 3110 of the wiring duct 3. Figure 1 In the embodiment, the end surface 81 of the restricting member 8 contacts the first peripheral surface 5101, the second peripheral 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. Thus, the restricting member 8 is attached to the wiring duct 3.

[0183] Furthermore, by switching the switch portion 82 to the locked state, the flat plate portion 80 covers a portion of the adapter 5, such as Figure 1 As shown, the lower surface of the shell 51 (the first peripheral surface 5101 of the adapter 5), the left side surface (the second peripheral surface 5102 of the adapter 5), and the end surface of the limiting recess 55 in the cover 56 are installed in the wiring duct 3 to limit the removal of the adapter 5.

[0184] When removing the limiting member 8, the operator inserts the switching key K1 into the key hole 821 again and rotates it counterclockwise, for example, so that the switching portion 82 is switched from the locked state to the unlocked state. Then, the operator grabs the limiting member 8 and moves the limiting member 8 forward (in the direction opposite to the insertion direction A1), thereby pulling out the cam portion 823 from the storage portion 3110 of the wiring duct 3. Once this state is reached, the operator can pull the limiting member 8 downward to disengage the limiting member 8 from the adapter 5. In addition, the use procedure of the limiting member 8 is not limited to the above-mentioned procedure.

[0185] As can be understood from the above description, the restriction member 8 of the present embodiment can be said to restrict the removal of the adapter 5 in two ways.

[0186] First, the restriction member 8 blocks the rotation of the adapter 5 by the flat plate-shaped portion 80 when the switching portion 82 is in the locked state, thereby restricting the removal of the adapter 5. Specifically, when the restriction member 8 is used, the end surface portion 81 of the flat plate-shaped portion 80 is in contact with the peripheral surface 510 of the adapter 5 and the end surface of the restriction recess 55, and surrounds the adapter 5. Therefore, even if the adapter 5 is to be pulled out by rotating it counterclockwise, the rotation of the adapter 5 is blocked because the housing 51 is surrounded by the end surface portion 81. However, as described above, the claw portion 520 of the operating portion 52 is inserted into the storage portion 3110, so the adapter 5 is also prevented from rotating by the operating portion 52. Therefore, the rotation of the adapter 5 is more firmly blocked.

[0187] Second, when the restricting member 8 is used, the flat plate portion 80 covers a portion of the surface of the operating portion 52 (particularly the grip portion 521). Therefore, it is difficult for a person (user, etc.) to operate the operating portion 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 a structure that covers the operating portion 52 in a manner that hinders the operation of the operating portion 52 when the switching portion 82 is in the locked state.

[0188] In the present embodiment, the adapter 5 can be moved along the length direction of the wiring duct 3. Furthermore, the limiting member 8 can be moved along the length direction integrally with the adapter 5 when the switching portion 82 is in the locked state. That is, the cam portion 823 is engaged with the two engaging portions 3111 of the first guide rail 311 in the wiring duct 3 to restrict the removal, but the cam portion 823 can be slid in the left and right directions along the two engaging portions 3111. Among them, the end surface portion 81 can surround the adapter 5, so that the limiting member 8 can be slidably moved in connection with the adapter 5. Therefore, the convenience of the user who uses the power supply from the wiring duct system 100 can be improved, while also maintaining the restriction on the removal of the adapter 5.

[0189] However, when the adapter 5 is set to be immovable in the longitudinal direction of the wiring duct 3, the restricting member 8 may also be set to be immovable in the longitudinal direction of the wiring duct 3. In addition, the structure of contacting at two or more places with the peripheral surface 510 of the adapter 5 may also be omitted. In this case, the flat plate portion 80 may have a second contact surface 812 in 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.

[0190] Even if the operating portion 52 is not provided on the adapter 5 , the restricting member 8 has the end surface portion 81 surrounding the adapter 5 , thereby preventing the adapter 5 from rotating and restricting the adapter 5 from being removed.

[0191] (12) Advantages

[0192] In this embodiment, by connecting the connector 95 of the electrical device 94 (or the cable connected to the electrical device 94) to the adapter 5 installed in the wiring duct 3, power can be supplied from the wiring duct 3 to the electrical device 94. Therefore, compared with the case where power is supplied from the power outlet or from the power tap that distributes the power of the power outlet to the electrical device 94, the handling of the wiring around the daily appliances can be improved. In addition, by replacing the adapter 5 with another adapter having a different output voltage to the connector 95, the supply voltage to the electrical device 94 can be easily changed.

[0193] Here, as described above, the wiring duct system 100 for supplying DC or AC power may be installed in a position that is relatively easy for a user to reach, such as a daily appliance such as a table 7. In this case, there is a possibility that the adapter 5 is taken out of the wiring duct 3 by the user or the like without authorization. In particular, when the wiring duct system 100 is applied to daily appliances such as public facilities such as libraries, hotels, or guesthouses, the users become an unspecified number of people, and therefore, the concern of taking out increases.

[0194] In contrast, the restricting member 8 of the present embodiment includes a switching portion 82 that restricts the removal of the adapter 5 from the wiring duct system 100. Therefore, unless the switching portion 82 is switched to the unlocked state by the switching key K1, the restricting member 8 restricts the removal of the adapter 5. As a result, the adapter 5 is less likely to be removed from the wiring duct 3.

[0195] In addition, in this embodiment, the adapter 5 is attached and detached by rotation. Since the rotation of the adapter 5 is blocked by the end surface 81 of the flat plate 80, the adapter 5 is not easily removed despite the simple structure.

[0196] Furthermore, in the present embodiment, the adapter 5 is detached by rotating and its rotation is restricted by inserting the operating portion 52, and the operation of the operating portion 52 is blocked by the flat plate portion 80. Therefore, although it is a simple structure, it is not easy to remove the adapter 5. In addition, in the present embodiment, although the plate thickness of the restricting member 8 is formed relatively thin compared with the past, the strength can be improved. Therefore, it is not easy to cause deformation caused by forcible removal of the restricting member, etc. Therefore, it is also more difficult to cause improper removal of the adapter due to theft, etc.

[0197] In particular, in the present embodiment, if the wall portion K2 is configured to sandwich both end portions of the adapter 5 in the longitudinal direction of the wiring duct 3 , removal of the adapter 5 can be further suppressed.

[0198] (Variation of the embodiment)

[0199] The following lists modifications of Embodiment 1. The following modifications may be implemented in combination as appropriate.

[0200] A part of the structure of the duct system 100 may be provided independently of other structures. For example, the duct 3, the duct fixing fixture F1, the first fixing portion 1 or the second fixing portion 2 (fixing member) may be provided independently of other structures.

[0201] The number of each structure 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 also have one or more than three wiring ducts 3. In addition, the wiring duct system 100 is not limited to having two first fixing portions 1, and may also have one or more than three first fixing portions 1. In addition, the wiring duct system 100 is not limited to having two second fixing portions 2, and may also have one or more than three second fixing portions 2. In addition, the partitioned duct system 200 is not limited to having three partitions 6, and may also have one, two, or more than four partitions 6.

[0202] The plurality of wiring ducts 3 may include two or more wiring ducts 3 arranged in the vertical direction. In addition, the voltage of the conductive rod 32 may be different for each of the two or more wiring ducts 3. In addition, the standard of the mountable adapter 5 may be different for each of the two or more wiring ducts 3. For example, the shape of the mountable adapter 5 may be limited for each of the two or more wiring ducts 3 by making the width or depth of the storage portion 3110 of the two or more wiring ducts 3 different. In this case, the limiting member K1 corresponding to the shape of the adapter 5 may be of multiple types.

[0203] The plate thickness of the restricting member 8 is preferably an appropriate dimension, and is preferably shorter than, for example, the length in the depth direction of the adapter 5. In this case, further miniaturization of the restricting member 8 and reduction in manufacturing cost can be achieved.

[0204] Alternatively, the end surface portion 81 of the limiting member 8 may be configured to surround the upper surface and the left and right side surfaces of the adapter 5 or surround the entire upper, lower, left and right peripheral surface when the limiting member 8 is installed. For example, in the embodiment, the limiting member 8 is configured to surround the adapter 5 from the lower side in the up-down direction, and the limiting member 8 may be configured so that the end surface portion 81 contacts the fourth peripheral surface 5104 of the adapter 5 from the upper side in the up-down direction.

[0205] The key hole 821 of the switch 82 is not limited to facing the front when the switch 82 in the restricting member 8 is switched. In addition, the switch 82 is located on the left side in the embodiment, but may be located on the right side.

[0206] As an example, the switch portion 82 may be a so-called cylinder lock. As described above, the switch portion 82 has a key hole portion 821 for inserting the switch key K1. The switch portion 82 is held by the flat portion 80 in a state where the key hole portion 821 faces the front. In addition, the switch portion 82 has a cam portion 823 that engages with the wiring duct 3 in the locked state. The cam portion 823 is assembled to the switch shaft portion 822 that is the cylindrical portion of the switch portion 82.

[0207] When the limiting member 8 has the third contact surface 813, it may not be disposed between the limiting recess 55 of the adapter 5 and the wiring duct 3. In this case, the third contact surface 813 may be a contact surface that contacts the third peripheral surface of the adapter. That is, in the embodiment, the flat plate-shaped bent piece 8013 of the limiting member 8 is accommodated between the adapter 5 and the duct guide 31 and can be set to a form that cannot be visually recognized, but the flat plate-shaped bent piece 8013 of the limiting member 8 may also be a form that can be visually recognized. More specifically, for example, Fig.19A and Fig.19BAs shown, when the peripheral surface 510 of the adapter 5 along the longitudinal direction of the wiring duct 3 in the locked state is set as the first peripheral surface 5101, the end surface 81 of the limiting member 8 has 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. The second contact surface 812 is a surface that contacts the second peripheral surface 5102. The third contact surface 813 is a surface that contacts the third peripheral surface 5103. In this case, even if the limiting recessed portion 55 is not formed in the cover portion 56 of the adapter 5, it is possible to contact the peripheral surfaces located at both ends, and each of the three peripheral surfaces as needed, so that the removal of the adapter 5 can be more firmly restricted. In addition, compared with the embodiment, although the aesthetics may be deteriorated because the portion of the flat bent piece 8013 including the third contact surface 813 (for example, the top end of the flat bent piece 8013) is visually recognizable, it can be firmly restricted and the effect of suppressing the carry-over can be improved.

[0208] The flat plate portion 80 may also be configured to clamp both ends of the adapter 5. In this case, the second contact surface 812 contacts the second peripheral surface 5102 of the adapter 5, and the third contact surface 813 contacts the third peripheral surface 5103 of the adapter 5 to clamp both ends of the adapter 5, i.e., the portions located at the second peripheral surface 5102 and the third peripheral surface 5103.

[0209] 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 .

[0210] Two or more wiring ducts 3 may be connected in their respective longitudinal directions (left-right directions).

[0211] As the second fixing part 2, a plurality of second fixing parts 2 of different specifications may be prepared, each having a different length of the cross-frame part 21. By replacing the second fixing part 2 with another second fixing part 2 of different specifications, the distance between the support parts 22 of the two second fixing parts 2 on both sides of the first fixing part 1 can be adjusted according to the length of the daily utensil (table 7).

[0212] The wiring duct 3 is not limited to being fixed to the top plate 71 of the table 7. The wiring duct 3 may be fixed to the side surface or the back surface of the top plate 71, for example.

[0213] The wiring duct 3 may be installed on daily appliances in a manner other than the length direction of the wiring duct 3 along the horizontal plane, for example, the wiring duct 3 may be installed on daily appliances in a manner such that the length direction of the wiring duct 3 is along the vertical direction. In addition, for example, the wiring duct 3 may be assembled on the side surface of the partition 6 along the vertical direction.

[0214] In the wiring duct 3 , a plurality of storage sections 3110 that can be included in the installation area may be provided and arranged in the longitudinal direction of the wiring duct 3 .

[0215] In addition, the connector 95 is not limited to a plug, and may be a jack (insertion port). The wiring duct 3 may be a first adapter that can be connected to the plug of the connector 95 and a second adapter that can be connected to the jack of the connector 95. Thus, it is also possible to handle an electrical device 94 or a cable having either a plug or a jack. The first adapter and the second adapter may have the same structure except for the connection portion with the connector 95.

[0216] The wiring duct system 100 may also be applied to Fig. 20 The table 7C (daily appliance) shown in the figure. Specifically, the table 7C is a table that assumes that the user only sits in front, for example, called a counter. The daily appliance (table 7C) has a pipe fixing device F2 that fixes the wiring duct 3. That is, the table 7C is formed integrally with the pipe fixing device F2.

[0217] The table 7C includes a table body 70, a pipe fixing device F2, and a back plate 74. The pipe fixing device F2 includes a first fixing portion 1C and two second fixing portions 2C. The table body 70 includes a top plate 701, a boss 702, and a support body 703. The wiring duct 3 is installed on the table 7C. The feed-in portion 4, the adapter 5, and the limiting member 8 (in Fig. 20 Figure omitted).

[0218] The duct system 100 is not limited to being applicable to daily appliances such as the table 7 and the table 7C, but may also be applied to surfaces such as walls and ceilings constituting interior decoration of buildings, and walls of vehicles such as railways.

[0219] In the embodiment, the wiring duct system 100 is described as a case where it is a direct current (DC), but it may also be an alternating current. That is, the power received by the wiring duct system 100 and supplied to the connector 95 may also be alternating current (AC) power. Therefore, the wiring duct system 100 may be either a DC wiring duct system or an AC wiring duct system.

[0220] The power supply system is described as including a switching hub 92 and a separator 93, but the present invention is not limited thereto. Fig.21As shown, the power supply system may also include an AC adapter 96 instead of the switching hub 92 and the separator 93. The AC adapter 96 converts the AC voltage supplied from the power supply 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.

[0221] Regarding the insertion port in the adapter 5, in the above-mentioned embodiment, the first insertion port 511 and the second insertion port 512 are insertion ports of different standards, but the first insertion port 511 and the second insertion port 512 may also be insertion ports of the same standard. In addition, the number of the insertion ports in the adapter 5 is not particularly limited, and may be, for example, 1 or more than 3.

[0222] (Summarize)

[0223] As described above, the first form of the limiting member 8 limits the removal of the adapter 5 from the wiring duct system 100. The wiring duct system 100 has a wiring duct 3 in which the adapter connected to the connector 95 is detachable, and the wiring duct system 100 supplies power to the connector 95 via the adapter 5. The limiting member 8 includes: a flat 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 using a switching key K1. The limiting member 8 is mounted on the wiring duct 3 in a state in which the end surface portion 81 contacts the at least a portion when the switching portion 82 is in the locked state. The plate thickness direction of the flat portion 80 is a direction orthogonal to the mounting surface 502 of the adapter 5. The end surface portion 81 is formed along the plate thickness direction.

[0224] According to this embodiment, as long as the switch portion 82 is not switched to the unlocked state by the switch key K1, the restricting member 8 restricts the removal of the adapter 5. As a result, the adapter 5 is less likely to be removed from the wiring duct 3.

[0225] The restriction member 8 of the second embodiment is different from the first embodiment in that the plate thickness of the flat plate-shaped portion 80 is smaller than the thickness of the adapter 5 in the direction toward the mounting surface 502 of the adapter 5 .

[0226] According to this aspect, the strength of the restricting member 8 is easily maintained, and the adapter 5 is less likely to be removed. In this case, it is also easy to contribute to the miniaturization of the restricting member 8 and the reduction of the manufacturing cost.

[0227] For the limiting member 8 of the third form, on the basis of the first form or the second form, the end surface portion 81 has: a first contact surface 811, which contacts the first circumferential surface 5101 of the adapter 5 along the length direction of the wiring duct 3 in the locked state; and a second contact surface 812, which contacts the second circumferential surface 5102 of the adapter 5 that intersects with the first circumferential surface 5101 in the locked state, and intersects with one end of the first contact surface 811.

[0228] According to this embodiment, the adapter 5 can be more firmly fixed by the restriction member 8 .

[0229] In the fourth embodiment of the restricting member 8, in addition to the third embodiment, the adapter 5 has a recessed portion 55 on the mounting surface 502, which is closer to the mounting surface 501 of the connector 95 with respect to the mounting surface 502. The flat portion 80 has a flat bent piece 8013, which intersects with the other end of the first contact surface 811 and is bent toward the side opposite to the side facing the first peripheral surface 5101 at a position closer to the second peripheral surface 5102 with respect to the third peripheral surface 5103 opposed to the second peripheral surface 5102. The tip of the flat bent piece 8013 is arranged between the recessed portion 55 and the wiring duct 3, and contacts the surface connecting the mounting surface 502 and the recessed portion 55.

[0230] According to this form, a part of the restricting member 8 supporting the adapter 5 can be set to be invisible. Therefore, it is not easy to excessively damage the appearance of the wiring duct system 100. In addition, in this case, it is difficult to put the user's fingers between the adapter 5 and the duct rail 31, and it is more difficult to remove it. Therefore, it is easy to exert a high restraining force against the removal of the adapter 5.

[0231] For the limiting member 8 of the fifth form, on the basis of the third form, the end surface portion 81 also has a third contact surface 813, which is in contact with the third circumferential surface 5103 of the adapter 5 and intersects with the other end of the first contact surface 811. The third circumferential surface 5103 intersects with the first circumferential surface 5101 and is opposite to the second circumferential surface 5102.

[0232] According to this aspect, the removal of the adapter 5 can be more firmly restricted.

[0233] The restriction member 8 according to the sixth embodiment is the same as that of any one of the first to fifth embodiments, in which the flat plate-shaped portion 80 and the switching portion 82 are formed integrally.

[0234] According to this aspect, it is easy to contribute to the miniaturization of the restricting member 8 and the reduction of the manufacturing cost.

[0235] The seventh embodiment of the restricting member 8 is based on any one of the first to sixth embodiments, wherein the wiring duct 3 has: a conductive rod 32; and a duct rail including a recessed storage portion 3110 for storing the conductive rod 32. The adapter 5 has a fixing rib 532, and the fixing rib 532 is inserted into the storage portion 3110, and the adapter 5 is rotated by a predetermined angle around a rotation axis along the insertion direction of the fixing rib 532, so that the adapter 5 is electrically connected to the conductive rod 32 and is prevented from being removed from the storage portion 3110. The restricting member 8 prevents the adapter 5 from rotating by the end surface portion 81 when the switch portion 82 is in the locked state.

[0236] According to this embodiment, even if the adapter 5 is to be pulled out, the housing 51 is surrounded by the end surface portion 81 and the rotation of the adapter 5 is blocked, thereby making it easier to restrict the removal of the adapter 5.

[0237] The limiting member 8 of the eighth embodiment is the same as that of the seventh embodiment, in which the adapter 5 has an operating portion 52 configured to be insertable and removable relative to the storage portion 3110, and the adapter 5 is restricted from rotating by inserting the operating portion 52 into the storage portion 3110. The flat plate portion 80 of the limiting member 8 covers the operating portion 52 in a manner that blocks the operation of the operating portion 52 when the switching portion 82 is in the locked state.

[0238] According to this embodiment, it is difficult for a person (user, etc.) to operate the operation portion 52 of the adapter 5 with a fingertip, etc. Therefore, it is easier to restrict the adapter 5 from being removed.

[0239] In the ninth embodiment, the limiting member 8 is configured such that the adapter 5 can be installed at any position in the installation area of ​​the wiring duct 3 that is continuous in the longitudinal direction, and can be moved in the longitudinal direction after installation. The limiting member 8 can be moved in the longitudinal direction integrally with the adapter 5 when the switching portion 82 is in the locked state.

[0240] According to this aspect, it is possible to improve the convenience of the user who uses the power supply from the duct system 100 while maintaining the restriction on the removal of the adapter 5 .

[0241] The restricting member 8 according to the tenth embodiment is configured in any one of the first to ninth embodiments, wherein the switching portion 82 includes a cam portion 823 that is engaged with the wiring duct 3 in a locked state.

[0242] According to this aspect, the removal of the adapter 5 can be more firmly restricted.

[0243] The restricting member 8 according to the eleventh embodiment is configured in any one of the first to tenth embodiments, wherein the switching portion 82 is configured to be switchable by a tool.

[0244] According to this embodiment, since the locking and unlocking of the switching portion 82 are switched by a tool, it is possible to make it more difficult for a person (user, etc.) to easily disassemble the restriction member 8 and the adapter 5 and remove the adapter 5.

[0245] The wiring duct system 100 of the twelfth embodiment includes: an adapter 5 connected to the connector 95; a wiring duct 3 having a conductive rod 32 and a duct rail 31, wherein the duct rail 31 includes a recessed storage portion 3110 for storing the conductive rod 32; and a limiting member 8 of any one of the first to eleventh embodiments. The wiring duct system 100 supplies power to the connector 95 via the adapter 5.

[0246] According to this embodiment, the adapter 5 is less likely to be removed from the wiring duct due to the restriction member 8 having high strength.
