Abstract
Description
Technical Field
[0001] The present disclosure generally relates to a wiring conduit system and a daily appliance, and more particularly to a wiring conduit system and a daily appliance with an adapter installed. Prior Art
[0002] Patent Document 1 (Japanese Patent Application Publication No. 2022-086852) discloses a DC (Direct Current) tube system. This DC tube system includes a detachable DC tube with an adapter to which a connector is connected, and supplies DC power to the connector via the adapter.
[0003] Here, the DC tube has a conductive rod and a tube track including a recess for receiving the conductive rod. The adapter is inserted into the recess with the fixing rib and rotated a predetermined angle about an axis of rotation along the insertion direction, thereby achieving electrical connection with the conductive rod and preventing it from being removed from the recess. Summary of the Invention
[0004] In Patent Document 1, even when the DC tube is accommodated in the accommodation groove of the first fixing portion, the adapter can be attached to and detached from the DC tube.
[0005] However, if the adapter has a structure that can only be installed or removed from the end of the DC tube, there is a problem that the DC tube must be removed from the receiving groove of the first fixing part when installing and removing the adapter.
[0006] The purpose of the present disclosure is to provide a wiring pipe system and daily necessities in which even if the wiring pipe is buried in the base, the adapter can be easily installed and removed from the wiring pipe.
[0007] One aspect of the present disclosure relates to a wiring conduit system equipped with an adapter to which a connector is connected, and power is supplied to the connector via the adapter. The wiring conduit system comprises: a wiring conduit extending in one direction, into which a portion of the adapter is inserted from one end in the one direction to mount the adapter; an end cap mounted on the one end of the wiring conduit and having the same width as the wiring conduit; and a detachable cover mounted on the end cap along the one direction and having the same width as the wiring conduit.
[0008] An everyday appliance according to one aspect of the present disclosure comprises the wiring conduit system and the adapter. Simple diagram description

[0010] 1. Summary The following describes the wiring duct system 3 and daily appliance 1 according to this embodiment with reference to the accompanying drawings. The following embodiments represent only a portion of the various embodiments disclosed herein. The following embodiments can be modified in various ways, depending on design considerations, as long as they achieve the objectives of this disclosure. The figures referenced in the following embodiments are schematic, and the sizes and thickness ratios of the components shown in the figures do not necessarily reflect actual dimensional ratios. The following embodiments, variations, and reference examples may also be implemented in appropriate combinations.
[0011] In the following figures, arrows indicating the vertical, horizontal, and front-to-back directions are provided solely for ease of explanation and do not represent the actual objects. Unless otherwise specified, "width direction" corresponds to the vertical direction, "length direction" and "unilateral direction" correspond to the horizontal direction, and "depth direction" corresponds to the front-to-back direction.
[0012] As shown in FIG14 , an adapter 2 is attached to the wiring conduit system 3 of this embodiment. Specifically, the adapter 2 is attached to the wiring conduit 31 of the wiring conduit system 3. Furthermore, a connector 8 is connected to the adapter 2. Furthermore, the wiring conduit system 3 supplies power to the connector 8 via the adapter 2.
[0013] One of the advantages of the wiring pipe system 3 of the present embodiment shown in FIG. 15 to FIG. 20 is that, even if the wiring pipe 31 is buried in the base 4 , the adapter 2 can be easily attached and detached relative to the wiring pipe 31 .
[0014] Here, based on the perspective of attachment and detachment from the wiring duct 31, the adapter 2 can be roughly divided into two types. The first adapter 2 has a structure that makes it difficult to attach to the wiring duct 31 from the front side (the side with the opening 32 formed). On the other hand, the second adapter 2 has a structure that makes it easy to attach to the wiring duct 31 from the front side. Hereinafter, the first adapter 2 will sometimes be referred to as the "adapter 2 of this embodiment," and the second adapter 2 will sometimes be referred to as the "adapter 2 of the reference example." The wiring duct system 3 of this embodiment is compatible with both types of adapters 2.
[0015] Before explaining the outline of the wiring duct system 3 of this embodiment, the adapter 2 of this embodiment will be explained. In addition, the adapter 2 of the reference example will be explained in the section "3. Variations".
[0016] As shown in Figure 1, the adapter 2 of this embodiment is mounted on a conduit 31 of a conduit system 3 that supplies power. Furthermore, as shown in Figure 14, a connector 8 is connected to the adapter 2. The conduit system 3 then transmits power from the conduit 31 through the adapter 2 to the connector 8. This allows the electrical equipment 9 connected to the connector 8 to receive power.
[0017] One of the characteristics of the adapter 2 shown in Figures 1 to 6 is that it is difficult to remove it from the wiring conduit 31 in the front-to-back direction. Consequently, it is also difficult to install the adapter 2 in the wiring conduit 31 in the front-to-back direction. However, the adapter 2 can be removed or installed from one end of the wiring conduit 31 in the left-to-right direction.
[0018] Figures 1, 3, and 5 illustrate the power supply state. This state is when power is supplied from the wiring duct 31 to the adapter 2. Specifically, as shown in Figure 3, the electrodes 34 of the wiring duct 31 are electrically connected to the power receiving terminals 22 of the adapter 2. In this power supply state, the adapter 2's securing ribs 23 engage with the fittings 37 of the wiring duct 31. In other words, as shown in Figure 5, the length L23 between the ends of the securing ribs 23 of the adapter 2 is longer than the width W32 of the opening 32 of the wiring duct 31. Consequently, it is difficult to remove the adapter 2 forward from the wiring duct 31.
[0019] On the other hand, Figures 2, 4, and 6 show the power-off state. This state is when no power is supplied from the wiring duct 31 to the adapter 2. Specifically, as shown in Figure 4, the electrodes 34 of the wiring duct 31 are not electrically connected to the power receiving terminals 22 of the adapter 2. Even in this power-off state, the adapter 2's securing ribs 23 remain engaged with the engagement portions 37 of the wiring duct 31. In other words, as shown in Figure 6, the length L23 between the ends of the securing ribs 23 of the adapter 2 is longer than the width W32 of the opening 32 of the wiring duct 31. Consequently, it is difficult to remove the adapter 2 forward from the wiring duct 31.
[0020] Thus, the adapter 2 of this embodiment is difficult to be pulled out forward relative to the wiring tube 31 in either the power supply state or the power non-supply state.
[0021] One of the features of the wiring duct system 3 of this embodiment is the use of a workspace 42 (see Figures 15 to 20) to achieve the aforementioned advantages. The workspace 42 is used during the installation and removal of the adapter 2. The workspace 42 is sealed by a detachable cover 6 before and after the installation and removal of the adapter 2.
[0022] When attaching or detaching the adapter 2, the detachment cover 6 (see Figure 16) is removed, followed by the end cap 5 (Figure 17). This creates a workspace 42. This workspace 42 allows the adapter 2 of this embodiment to be attached or detached from the end of the wiring conduit 31. During detachment, the wiring conduit 31 need not be removed from the base 4. As described above, the detachment cover 6 blocks the workspace 42 before and after the adapter 2 is attached or detached, thus preserving the aesthetic appearance. When attaching or detaching the adapter 2 in the reference example, there is no need to remove or attach the end cap 5 and detachment cover 6.
[0023] Therefore, according to this embodiment, even if the wiring pipe 31 is embedded in the base 4 , the adapter 2 can be easily attached to and detached from the wiring pipe 31 .
[0024] 2. Details (1) Adapter First, referring to FIG. 1 to FIG. 6 , the adapter 2 of this embodiment will be described.
[0025] The adapter 2 includes a housing 24, an operating portion 25, a mounting protrusion 26, two power receiving terminals 22, a spring housed in the housing 24, and a cover 27. The adapter 2 also includes a pair of USB (Universal Serial Bus) connectors housed in the housing 24, a circuit board, and other components. The housing 24, mounting protrusion 26, two power receiving terminals 22, a pair of USB connectors, a circuit board, and the cover 27 comprise the adapter body 20.
[0026] The housing 24 is made of, for example, resin. It is a hollow box with one side (the rear side) open. To seal the open side of the housing 24 with a cover 27, the cover 27 is assembled to the housing 24 by screws or the like (see Figures 5 and 6). The outer shape of the housing 24 is a rectangular parallelepiped. The housing 24 has a first inlet 241 and a second inlet 242. The first inlet 241 serves as an inlet for the USB Type-A plug of the connector 8 (see Figure 14). The second inlet 242 serves as an inlet for the USB Type-C plug of the connector 8. Specifically, the specifications of the first inlet 241 and the second inlet 242 are different. The first inlet 241 and the second inlet 242 are different in size. Within the housing 24, a pair of connecting connectors are mounted on the circuit board in a one-to-one correspondence with the first inlet 241 and the second inlet 242, respectively. The connector 8 connected to the first inlet 241 or the second inlet 242 is connected to a corresponding one of a pair of connection connectors and is electrically connected to the power receiving terminal 22 via the circuit board.
[0027] When the adapter 2 is mounted on the wiring conduit 31, the first inlet 241 and the second inlet 242 are located on the surface facing away from the wiring conduit 31 (the connector mounting surface 201: the front surface in FIG. 1 , etc.). When the adapter 2 is mounted on the wiring conduit 31, the first inlet 241 and the second inlet 242 are aligned vertically as shown in FIG. 1 , etc.
[0028] The cover 27 is made of resin, for example. A mounting protrusion 26 is provided on the rear surface of the cover 27 (see FIG. 3 to FIG. 6 ). The cover 27 and the mounting protrusion 26 are formed continuously and integrally. The mounting protrusion 26 includes a shaft 21 and a fixing rib 23 .
[0029] The shaft 21 protrudes from the housing 24 toward the side opposite the connector mounting surface 201. The shaft 21 is inserted into the opening 32 of the wiring duct 31 (see Figures 3 and 4). The central axis of the shaft 21 is approximately aligned with the rotation axis B1. The adapter 2 is rotated relative to the wiring duct 31 about the rotation axis B1 by a predetermined angle (e.g., 90 degrees). The rotation axis B1 is a virtual axis.
[0030] The fixing rib 23 protrudes from the side of the shaft portion 21. Specifically, as shown in Figures 3 to 6, the fixing rib 23 protrudes from the shaft portion 21 with the shaft portion 21 as the center. In other words, the fixing rib 23 protrudes radially outward of a virtual circle centered on the rotation axis B1.
[0031] In this embodiment, the fixing rib 23 protrudes from the entire circumference of the shaft portion 21. The fixing rib 23 has a thick-walled portion 234 and a thin-walled portion 235 (see Figures 3 to 6). The thin-walled portion 235 is thinner than the thick-walled portion 234. The thin-walled portion 235 exists on a portion of the outer circumference of the fixing rib 23. The thin-walled portion 235 includes a first edge portion 231, a second edge portion 232, and a third edge portion 233. The first edge portion 231 is a portion extending in one direction with a constant width. The second edge portion 232 is a portion extending in a direction perpendicular to the first edge portion 231 with the same width as the first edge portion 231. The third edge portion 233 is a portion having the same width as the first edge portion 231 and the second edge portion 232, forming an arc-shaped portion that smoothly connects the first edge portion 231 and the second edge portion 232.
[0032] Furthermore, in this embodiment, when no power is supplied (i.e., the power non-supply state shown in Figures 4 and 6), when observed from the depth direction (front-to-back direction) orthogonal to both the length direction and the width direction, the length L23 between the two ends of the fixed rib 23 in the width direction is longer than the width W32 of the opening 32 (refer to Figure 6).
[0033] More specifically, in this embodiment, the length L23 between the ends of the fixing rib 23 in any radial direction centered on the shaft 21 is longer than the width W32 of the opening 32. In other words, when viewed in the front-to-back direction, the distance between two intersection points of a straight line intersecting the rotation axis B1 and the outer periphery of the fixing rib 23 is longer than the width W32 of the opening 32.
[0034] The two power receiving terminals 22 protrude from the shaft portion 21 in opposite directions. Specifically, the two power receiving terminals 22 protrude in opposite directions within a plane perpendicular to the front-to-back direction (see Figures 5 and 6). The length L23 between the ends of the fixing rib 23 in the direction in which the two power receiving terminals 22 protrude (the vertical direction in Figure 5) is greater than the width W32 of the opening 32. The two power receiving terminals 22 are electrically connected to the circuit board. The adapter 2 receives power from the wiring duct 31 through the two power receiving terminals 22 (see Figure 3).
[0035] The adapter 2 has a limiting recess 28 (see Figures 5 and 6). The limiting recess 28 is formed by a recess formed by the rear end surface of the housing 24 and the surface of the cover 27. Specifically, the limiting recess 28 includes a first recess 281 and a second recess 282.
[0036] A portion of the rear end surface of the housing 24 in the first recess 281 is formed so as to be stepped down toward the connector mounting surface 201. In Figures 5 and 6, the area of the first recess 281 is shown by dark shadows for easier understanding.
[0037] In the second recess 282, a portion of the surface of the cover portion 27 is formed so as to step down toward the connector mounting surface 201. In Figures 5 and 6, the area of the second recess 282 is shown by lightly shaded areas and areas surrounded by lightly shaded areas for easier understanding. The bottom surfaces of the first recess 281 and the second recess 282 are substantially flush.
[0038] The operating portion 25 is configured to be inserted and removed from the opening 32. By engaging the opening 32, the adapter 2 is restricted from rotating. The operating portion 25 is retained by the housing 24. The operating portion 25 is made, for example, of resin and is plate-shaped. The operating portion 25 has an anti-slip portion 251 on its surface, with a surface of the anti-slip portion 251 retained by the housing 24, with a portion of the anti-slip portion 251 exposed from one side of the housing 24. The operating portion 25 can slide in a predetermined direction (front-to-back in FIG. 1 ) by applying force to the anti-slip portion 251 with a fingertip or the like. The operating portion 25 is retained by the housing 24 while the restoring force of a spring housed within the housing 24 acts in a direction away from the connector mating surface 201 (toward the rear). Therefore, when no force is applied to the operating portion 25, the front end (claw 250) of the operating portion 25 protrudes from the housing 24 toward the side opposite the connector mating surface 201. By applying a force forward to the anti-slip portion 251 with a fingertip or the like against the force of the spring, the operating portion 25 slides forward.
[0039] Adapter 2 further includes a power converter. The multiple electronic components that comprise the power converter are mounted on a circuit board within housing 24. The power converter converts power received by the two power receiving terminals 22 into power of the required voltage. The power converted by the power converter is output from a pair of connecting connectors (USB ports). Electrical equipment 9 (see FIG. 14 ) can receive power via a cable that includes connector 8 (see FIG. 14 ), which is connected to the connecting connector and is connected to the first inlet 241 or the second inlet 242.
[0040] (2) Wiring pipe system 15 to 20, the wiring conduit system 3 of the present embodiment will be described.
[0041] The wiring duct system 3 is used as a part of, for example, an everyday appliance 1 (described later). The wiring duct system 3 includes a wiring duct 31, an end cap 5, and a detachable cover 6. Although the base 4 is shown in Figures 15 to 20, the base 4 will be described later.
[0042] The wiring conduit 31 is a member extending in one direction. Thus, the wiring conduit 31 extends in the longitudinal direction (in this embodiment, the left-right direction). The wiring conduit 31 includes a conduit rail 35 and a pair of electrodes 34. The conduit rail 35 includes a first rail 351 and two second rails 352.
[0043] The first rail 351 is in the shape of a square tube. The first rail 351 is made of metal, for example. The first rail 351 extends in the longitudinal direction (left-right direction).
[0044] The first rail 351 includes an opening 32. The opening 32 is formed along the longitudinal direction (left-right direction) of the pipe rail 35. More specifically, the opening 32 spans both ends of the longitudinal direction of the pipe rail 35. Thus, the opening 32 is formed in the wiring duct 31 and extends in the longitudinal direction (left-right direction) of the wiring duct 31.
[0045] In this embodiment, the opening 32 opens forward. The width W32 of the opening 32 is narrower than the width W31 of the wiring duct 31 (see Figures 5 and 6). The width W31 of the wiring duct 31 is equal to the width of the duct rail 35 and the width of the first rail 351.
[0046] The first rail 351 further includes a limiting protrusion 39. The limiting protrusion 39 is a protrusion. The limiting protrusion 39 is provided at the lower portion of the first rail 351. The limiting protrusion 39 is inserted into the limiting recess 28 of the adapter 2.
[0047] The wiring duct 31 has end openings 36 at both ends in the longitudinal direction (left-right direction). One end opening 36 opens to the right, and the other end opening 36 opens to the left. The two end openings 36 are connected to the opening 32.
[0048] As shown in FIG. 3 and FIG. 4 , the first rail 351 further includes two fitting portions 37 and two mounting grooves 38 .
[0049] Each of the two engaging portions 37 is a groove. The two engaging portions 37 are provided on the inner surface of the tube rail 35 (first rail 351). The two engaging portions 37 face each other in the vertical direction. The two engaging portions 37 are formed along the longitudinal direction (left-right direction) of the tube rail 35. More specifically, the two engaging portions 37 are formed across both ends of the longitudinal direction of the tube rail 35.
[0050] As shown in Figures 3 and 4, the two interlocking portions 37 have different widths (groove widths). The width of one (upper) interlocking portion 37 is approximately equal to the thickness of the thick-walled portion 234 of the fixing rib 23. The other (lower) interlocking portion 37 has a wide portion 371 and a narrow portion 372. The narrow portion 372 is narrower than the wide portion 371. The narrow portion 372 is vertically connected to the wide portion 371. The width of the wide portion 371 is approximately equal to the thickness of the thick-walled portion 234 of the fixing rib 23. The width of the narrow portion 372 is approximately equal to the thickness of the thin-walled portion 235 of the fixing rib 23.
[0051] The two engaging portions 37 engage with the fixing ribs 23 of the adapter 2. This allows the adapter 2 to be mounted on the wiring duct 31. Specifically, the duct rail 35 (first rail 351) includes an adapter mounting portion (two engaging portions 37) for mounting the adapter 2. The procedure for mounting the adapter 2 on the wiring duct 31 will be described later.
[0052] Two mounting grooves 38 are provided on the inner surface of the tube rail 35 (first rail 351). The two mounting grooves 38 face each other in the vertical direction. Of the two fitting portions 37 and the two mounting grooves 38, the two fitting portions 37 are provided near the opening 32. The two mounting grooves 38 are formed along the longitudinal direction (left-right direction) of the tube rail 35. More specifically, the two mounting grooves 38 are formed across both ends of the longitudinal direction of the tube rail 35.
[0053] The two mounting grooves 38 correspond to the two second rails 352 in a one-to-one manner. A corresponding second rail 352 is embedded in each mounting groove 38. Thus, the two second rails 352 are mounted on the first rail 351.
[0054] Each of the two second rails 352 extends in the longitudinal direction (lateral direction). The two second rails 352 face each other in the vertical direction. The second rails 352, taken in a cross-section perpendicular to the lateral direction, are U-shaped. The second rails 352 are electrically insulating. They are formed from a synthetic resin material such as PVC (polyvinyl chloride). The second rails 352 hold the electrodes 34 within them.
[0055] A pair of electrodes 34 is disposed at both ends of the wiring tube 31 in the width direction (in this embodiment, the vertical direction). Thus, the pair of electrodes 34 face each other in the vertical direction. Each pair of electrodes 34 extends in the longitudinal direction (left-right direction). Each pair of electrodes 34 is disposed from the right end to the left end of the tube rail 35. The pair of electrodes 34 is electrically connected to the corresponding wiring W1 via the feedthrough 91 (see Figure 14). One of the pair of electrodes 34 in the wiring tube 31 is electrically connected to the wiring W1 on the positive side, and the other is electrically connected to the wiring W1 on the negative side. This supplies DC power to the pair of electrodes 34. The two power receiving terminals 22 of the adapter 2 receive the power supply by connecting to the pair of electrodes 34.
[0056] The end cap 5 is attached to one end of the wiring duct 31 (the right end in this embodiment). This closes the end opening 36 of the wiring duct 31. The end cap 5 comprises a closing portion 51, two guide portions 52, an insert portion 54, and two insert pieces 55. A feedthrough 91 (see Figure 14) is attached to the other end of the wiring duct 31.
[0057] When viewed from the left and right sides, the outer periphery of the blocking portion 51 is substantially the same as the outer periphery of the wiring duct 31. In this embodiment, the blocking portion 51 is in the shape of a rectangular plate. The width of the blocking portion 51 is equal to the width W5 of the end cap 5. The end cap 5 has the same width as the width W31 of the wiring duct 31.
[0058] An inclined surface 57 is formed in front of the blocking portion 51. The inclined surface 57 is a surface that is inclined so as to extend rearward as it goes toward the right side.
[0059] Two guide portions 52 are formed on one surface of the blocking portion 51 (the surface facing the right side in this embodiment). When viewed from the front-to-back direction, each guide portion 52 is L-shaped. Each guide portion 52 extends in the front-to-back direction. A guide groove 53 is formed between the front end of each guide portion 52 and one surface of the blocking portion 51. The guide groove 53 extends in the front-to-back direction. The two guide grooves 53 open to opposite sides. Specifically, the upper guide groove 53 opens upward, while the lower guide groove 53 opens downward.
[0060] The insertion portion 54 is a portion that is inserted from the end surface opening 36 of the wiring pipe 31 into the interior of the wiring pipe 31. The insertion portion 54 is formed on the other surface of the closing portion 51 (the surface facing the left side in this embodiment).
[0061] A fixing hole 56 is formed in the insertion portion 54. This hole is used to secure the end cap 5 to the wiring duct 31. The fixing hole 56 opens in the front-to-back direction. A special screw is screwed into the fixing hole 56 using a special tool. A special screw is a screw with a shape that cannot be turned with a standard screwdriver (e.g., a positive screwdriver, a negative screwdriver, etc.). An example of a special screw is a screw with a hexagonal star-shaped hole. A special tool is a tool that can turn a special screw. In this manner, the end cap 5 is attached to the wiring duct 31 using a special tool.
[0062] Two insertion pieces 55 are formed on the upper and lower sides of the insertion portion 54, respectively. The two insertion pieces 55 extend in the left-right direction. The two insertion pieces 55 correspond one-to-one with the two fitting portions 37 of the first rail 351. The upper insertion piece 55 fits into the upper fitting portion 37, and the lower insertion piece 55 fits into the lower fitting portion 37.
[0063] The removable cover 6 is removable relative to the end cap 5. It is attached to the end cap 5 in one direction (left-right). In this embodiment, the removable cover 6 is attached adjacent to the right side of the end cap 5. It has a rectangular box shape. It includes a main body 60 and two guide pieces 61 (see Figure 19).
[0064] The main body 60 is a rectangular box with openings on the rear and left sides. The width of the main body 60 is equal to the width W6 of the detachable cover 6. The detachable cover 6 has the same width W31 as the width of the wiring duct 31. Specifically, the width W31 of the wiring duct 31, the width W5 of the end cap 5, and the width W6 of the detachable cover 6 are equal.
[0065] An inclined surface 62 is formed on the left front side of the main body 60. Inclined surface 62 extends rearward as it approaches the right side. Inclined surface 62 faces inclined surface 57 of the end cap 5. Thus, inclined surface 62 of the detachable cover 6 faces inclined surface 57 of the end cap 5, forming a detachment hole 63 therebetween. A general-purpose tool, such as a screwdriver, is inserted into detachment hole 63, and the detachable cover 6 is pulled forward using the principle of leverage. This allows the detachable cover 6 to slide in a direction perpendicular to one direction and the width of the wiring duct 31 (in this embodiment, the front-to-back direction).
[0066] The two guide pieces 61 correspond one-to-one with the two guide grooves 53 of the end cap 5. Each guide piece 61 extends in the front-to-back direction. The two guide pieces 61 face each other in the vertical direction. That is, the upper guide piece 61 protrudes downward, and the lower guide piece 61 protrudes upward. The thickness of the guide pieces 61 is approximately equal to the thickness of the guide grooves 53. Each guide piece 61 is inserted into the corresponding guide groove 53. This allows the detachable cover 6 to slide in the front-to-back direction relative to the end cap 5 while being coupled to the end cap 5.
[0067] In one direction (left-right), the length L6 of the detachable cover 6 is longer than the length L5 of the end cap 5. In one direction (left-right), the length L6 of the detachable cover 6 is longer than the length of the portion of the adapter 2 inserted into the wiring conduit 31. Here, "portion of the adapter 2" refers to the portion located further rearward than the rear surface of the cover 27. Specifically, the mounting protrusion 26. Preferably, when viewed in the front-to-back direction, the length L6 of the detachable cover 6 is longer than the distance between two intersection points of a straight line intersecting the rotation axis B1 and the outer periphery of the fixing rib 23.
[0068] (3) Daily necessities 13 and 14, the daily necessities 1 of this embodiment will be described.
[0069] The daily utensil 1 includes an adapter 2 and a wiring conduit system 3. FIG13 shows the daily utensil 1 with the adapter 2 removed from the wiring conduit system 3.
[0070] Here, "daily items 1" collectively refer to furniture and other appliances used in residential and non-residential settings. Examples of daily items 1 include tables, machine tables, and workbenches used as storage platforms. Other examples of daily items 1 include shelves, boxes, dressers, beds, whiteboards, monitors, dividers, and benches.
[0071] Although the following description will be given of a case where the daily utensil 1 is a table 10 , the daily utensil 1 is not limited to being the table 10 .
[0072] The daily tool 1 further includes a table 10 , a pipe fixture 11 , and a partition 12 .
[0073] Table 10 has a rectangular top plate 13, two legs 14, and two support platforms 15 when viewed from above. One of the two legs 14 protrudes downward from near the right end of the top plate 13, and the other protrudes downward from near the left end of the top plate 13. The two support platforms 15 correspond one-to-one with the two legs 14. Each support platform 15 is connected to the lower end of the corresponding leg 14 to support the leg 14.
[0074] The pipe fixture 11 is a member for fixing the wiring pipe system 3 to the table 10. The pipe fixture 11 has a first fixing portion 111 and a second fixing portion 112.
[0075] The first fixing portion 111 is a member for holding the wiring duct system 3. The first fixing portion 111 extends in the left-right direction and is arranged in a manner to partition the table 10 into front and back.
[0076] The second fixing portion 112 is a member for fixing the first fixing portion 111 to the table 10. The second fixing portion 112 is connected to the left and right ends of the first fixing portion 111. The second fixing portion 112 includes a clamp mechanism that clamps the table 10 in the vertical direction and is fixed to the table 10.
[0077] Partition 12 is a rectangular plate held by pipe fixture 11. Partition 12 separates the front and back of table 10. In this embodiment, partition 12 is light-transmissive. Partition 12 is made of, for example, acrylic resin.
[0078] 14, an example of a power supply system for a daily appliance 1 will be described. The power supply system is a system that uses an adapter 2 and a wiring conduit system 3 to supply power to an electrical device 9.
[0079] The type of electrical device 9 is not particularly limited. Examples of the electrical device 9 include computer terminals (personal computers, smartphones, tablet terminals, etc.), computer terminal accessories (monitors, speakers, microphones, etc.), lighting devices (desk lamps, etc.), web cameras, sensors (temperature sensors, humidity sensors, illuminance sensors, etc.), game consoles, and air conditioners (desktop fans, etc.).
[0080] As shown in FIG14 , a switching hub 93 and a splitter 94 are installed in the facility where the electrical equipment 9 is used. The switching hub 93 is electrically connected to a power supply 92. The power supply 92 supplies AC power to the switching hub 93. The power supply 92 is, for example, a commercial power supply or a distributed power supply.
[0081] Switching hub 93 is a PoE (Power over Ethernet) switching hub. Switching hub 93 is electrically connected to splitter 94 via a LAN (Local Area Network) cable. Switching hub 93 can also be electrically connected to PoE-compatible devices. Examples of PoE-compatible devices include computer terminals, web cameras, IP (Internet Protocol) phones, and wireless access points. Switching hub 93 can exchange PoE signals, which carry both data and power (DC power), with devices electrically connected to it.
[0082] Splitter 94 is a PoE splitter compatible with PoE. Splitter 94 separates the PoE signal received from switching hub 93 into data and power (DC power). Splitter 94 supplies the power separated from the PoE signal to non-PoE-compatible devices. For example, splitter 94 supplies the power separated from the PoE signal to one or more non-PoE-compatible electrical devices 9 via the wiring conduit system 3.
[0083] The splitter 94 sends the data signal including the data separated from the PoE signal to a device that does not support PoE.
[0084] The DC power output terminal of the separator 94 is electrically connected to the first end of each of two wires W1. These two wires W1 are the positive and negative wires. The two wires W1 correspond one-to-one with the two electrodes 34 of the wiring conduit 31. The second end of each of the two wires W1 is electrically connected to the corresponding electrode 34 via the feedthrough 91. The adapter 2 can be connected to the wiring conduit 31, and the electrical device 9 can be electrically connected to each electrode 34 via the adapter 2.
[0085] As described above, the electric device 9 can receive power supplied from the wiring W1 via the electrode 34 and the adapter 2. The user can use the electric device 9 on or around the table 10 (see FIG. 13).
[0086] (4) Installation and removal of the adapter relative to the wiring conduit Next, referring to Figures 15 to 20 , the attachment and detachment of the adapter 2 to the wiring conduit 31 will be described. The base 4 shown in Figures 15 to 20 corresponds to the first fixing portion 111 of the everyday tool 1 shown in Figure 13 . For ease of explanation, the base 4 is shown as a rectangular parallelepiped, but is not limited to this shape.
[0087] A storage groove 41 and a work space 42 are formed on a surface (the front surface in this embodiment) of the base 4. The storage groove 41 and the work space 42 are recessed toward the rear.
[0088] The storage groove 41 is a groove for storing the wiring conduit 31. The wiring conduit 31 stored in the storage groove 41 is exposed from the base 4. Specifically, the front surface of the wiring conduit 31 (the surface formed with the opening 32) is exposed from the base 4. The end cap 5 (the front portion) attached to the wiring conduit 31 is also exposed from the base 4.
[0089] The storage groove 41 extends in the left-right direction. The width of the storage groove 41 is approximately equal to the width W31 of the wiring conduit 31. The depth of the storage groove 41 is approximately equal to the front-to-back length of the wiring conduit 31. Thus, the wiring conduit 31, with the exception of the restraining protrusion 39, does not protrude from the base 4. The wiring conduit 31 is secured to the storage groove 41 by screws or the like. The end cap 5 attached to the wiring conduit 31 also does not protrude from the base 4.
[0090] The workspace 42 is used during the installation and removal of the adapter 2 (see Figures 16 and 17). Furthermore, before and after the installation and removal of the adapter 2, the workspace 42 is blocked by the detachable cover 6. This allows the detachable cover 6 to be exposed from the base 4. Specifically, the surface of the detachable cover 6 is exposed from the base 4 before the detachable cover 6 is removed.
[0091] The workspace 42 is formed continuously with one end of the storage tank 41 (the right end in this embodiment). The width of the workspace 42 is approximately equal to the width of the storage tank 41. The depth of the workspace 42 is approximately equal to the depth of the storage tank 41. The length L42 of the workspace 42 is approximately equal to the length L6 of the detachable cover 6 and is longer than the length L5 of the end cap 5 (see Figure 19). The depth of the workspace 42 is approximately equal to the height (distance in the front-to-back direction) of the detachable cover 6 (see Figure 20). Therefore, the surface (front surface) of the base 4 and the surface (front surface) of the detachable cover 6 are approximately flush. In this way, the detachable cover 6 does not protrude from the base 4.
[0092] Next, the procedure for mounting the adapter 2 on the wiring duct 31 will be described.
[0093] As shown in FIG. 15 , when the installation operation of the adapter 2 begins, the wiring tube 31 , the end cap 5 and the detachable cover 6 are buried in the base 4 .
[0094] First, insert a general tool such as a screwdriver into the disassembly hole 63 and pull the disassembly cover 6 forward using the lever (see FIG16 ). This creates a work space 42 .
[0095] Next, slide the end cap 5 to the right and move it into the work space 42. Then, pull the end cap 5 forward from the work space 42 (see Figure 17). Because the length L42 of the work space 42 is longer than the length L5 of the end cap 5 (see Figure 19), the end cap 5 can be easily pulled out of the work space 42.
[0096] Next, partially insert the adapter 2 from one end of the wiring duct 31 (the end opening 36 facing the workspace 42). As mentioned above, "partially" refers to the portion of the adapter 2 located further rearward than the rear surface of the cover 27 (the mounting protrusion 26). Here, the fitting portion 37 of the wiring duct 31 opens into the end opening 36. Therefore, the fixing rib 23 of the adapter 2 can be inserted horizontally into the fitting portion 37 of the wiring duct 31, engaging the fitting. The adapter 2 is then moved horizontally to a desired position (the user's desired position) within the wiring duct 31. To prevent wear on the two power receiving terminals 22, it is best to move the adapter 2 while the two power receiving terminals 22 are positioned longitudinally (horizontally). This is the non-power supply state (see Figure 4), so the two power receiving terminals 22 are not in contact with the electrodes 34 and are not receiving power.
[0097] When partially inserting the adapter 2 through the end opening 36 of the wiring duct 31, the thick portion 234 of the fixing rib 23 is inserted into the wide portion 371 of the fitting portion 37, and the thin portion 235 of the fixing rib 23 is inserted into the narrow portion 372 of the fitting portion 37 (see Figure 4). If the adapter 2 is not oriented correctly, the thick portion 234 of the fixing rib 23 interferes with the narrow portion 372 of the fitting portion 37, making it impossible to insert the adapter 2 through the end opening 36 of the wiring duct 31.
[0098] In a similar manner to the above, when partially inserting the adapter 2 through the end opening 36 of the wiring conduit 31, the restricting protrusion 39 of the wiring conduit 31 is inserted into the restricting recess 28 (see Figure 4). If the adapter 2 is oriented incorrectly, the restricting protrusion 39 interferes with the area on the rear surface of the adapter 2 that protrudes one level higher than the restricting recess 28, making it impossible to insert the adapter 2 through the end opening 36 of the wiring conduit 31. In other words, the restricting recess 28 and restricting protrusion 39 restrict the orientation of the adapter 2.
[0099] Next, as shown in Figure 2 (base 4 omitted), after the adapter 2 is moved to the designated position within the wiring conduit 31, it is rotated 90 degrees about the rotation axis B1 (see Figure 1). This transitions from the power-off state shown in Figure 4 to the power-on state shown in Figure 3. Specifically, the two power receiving terminals 22 contact the electrodes 34, receiving power. Furthermore, as shown in Figures 1 and 3, the claw 250 of the operating portion 25 is inserted into the opening 32 of the wiring conduit 31, restricting the rotation of the adapter 2 (housing 24).
[0100] Next, move the end cap 5 in the direction opposite to the arrow in Figure 17. That is, after placing the end cap 5 in the work space 42, insert the insert piece 55 of the end cap 5 into the fitting portion 37 of the wiring duct 31 and slide it directly to the left. This closes the end opening 36 of the wiring duct 31 with the end cap 5.
[0101] Next, move the detachable cover 6 in the direction opposite to the arrow in Figure 16. That is, insert the guide piece 61 of the detachable cover 6 into the guide groove 53 of the end cap 5, and then slide the detachable cover 6 backward into the working space 42. This allows the detachable cover 6 to block the working space 42 (see Figure 15).
[0102] According to the above procedure, the adapter 2 can be installed on the wiring duct 31. In addition, if the above procedure is followed in reverse, the adapter 2 can be removed from the wiring duct 31.
[0103] 3. Variations (1) Variations of the adapter 7 to 10 , a modified example of the adapter 2 will be described. In this modified example, the same components as those in the above embodiment are assigned the same reference numerals as those in the above embodiment, and detailed description thereof will be omitted.
[0104] The shape of the fixing rib 23 of the adapter 2 of the modified embodiment differs from that of the adapter 2 of the aforementioned embodiment. Specifically, when viewed from the front-to-back direction, the fixing rib 23 of the adapter 2 of the modified embodiment is circular, centered on the rotation axis B1. The outer periphery of the thick-walled portion 234 and the outer periphery of the thin-walled portion 235 are concentric circles. Between the outer peripheries of the thick-walled portion 234 and the thin-walled portion 235 lies an annular outer peripheral edge 236.
[0105] (2) Reference example of adapter 11 and 12, a reference example of the adapter 2 will be described. In this reference example, the same components as those in the above embodiment are assigned the same reference numerals as those in the above embodiment, and detailed description thereof will be omitted.
[0106] The shape of the fixing rib 23 of the reference example adapter 2 differs from that of the adapter 2 of the aforementioned embodiment. Specifically, the length L23 between the ends of the fixing rib 23 in the direction in which the two power receiving terminals 22 protrude (the vertical direction in FIG. 11 ) is longer than the width W32 of the opening 32. However, the length L23 between the ends of the fixing rib 23 in the direction perpendicular to the protruding direction of the two power receiving terminals 22 (the vertical direction in FIG. 12 ) is less than the width W32 of the opening 32.
[0107] (3) Others In this embodiment, the wiring conduit system 3 is described as a DC conduit system that supplies DC (direct current) power, but the wiring conduit system 3 may also be an AC conduit system that supplies AC (alternating current) power.
[0108] In this embodiment, a switching hub 93 and a splitter 94 are installed in the facility at the location where the electrical device 9 is used (see FIG14 ). However, this is not limiting. For example, an AC adapter may be provided in place of the switching hub 93 and the splitter 94. The AC adapter converts the AC power supplied from the power source 92 into DC power. For example, the AC adapter may be configured to convert 100 V AC power into 24 V DC power.
[0109] In this embodiment, the end cap 5 and the detachable cover 6 are mounted on the right end of the wiring duct 31 , but they may also be mounted on the left end of the wiring duct 31 .
[0110] 4. Advantages The advantages of the adapter 2, the wiring conduit system 3, and the daily appliance 1 of this embodiment are described below.
[0111] The adapter 2 of this embodiment suppresses dragging out from the wiring duct 31 as compared to the adapter 2 of the reference example.
[0112] In the reference example adapter 2, particularly in the power-off state, the length L23 between the ends of the fixing rib 23 is shorter than the width W32 of the opening 32 of the wiring duct 31 (see Figure 12). Therefore, if the reference example adapter 2 is rotated about the rotation axis B1 from the power-on state to the power-off state, essentially anyone can remove the adapter 2 from the wiring duct 31.
[0113] In contrast, in the adapter 2 of this embodiment, the length L23 between the ends of the fixing rib 23 is longer than the width W32 of the opening 32 of the wiring duct 31 (see Figure 6), particularly when power is off. Therefore, when power is off, even if the adapter 2 is pulled forward (frontward), the fixing rib 23 interferes with the edge of the opening 32, making it difficult to remove the adapter 2 from the wiring duct 31. This prevents the adapter 2 from being pulled out of the wiring duct 31. However, when power is off, the adapter 2 is only difficult to move forward and backward; it can move left and right. In other words, the adapter 2 of this embodiment can move freely along the length (left and right) of the wiring duct 31 even when it is not separated from the wiring duct 31.
[0114] In the adapter 2 of this embodiment, the length L23 between the ends of the fixing rib 23 is longer than the width W32 of the opening 32 of the wiring duct 31 (see Figure 5 ), especially when power is supplied. Therefore, even when power is supplied, the adapter 2 is prevented from being removed from the front surface of the wiring duct 31 (the surface where the opening 32 is formed). The same applies to the adapter 2 of the modified example.
[0115] Furthermore, in the adapter 2 of this embodiment, the length L23 between the ends of the fixing rib 23 in any radial direction centered on the shaft 21 (particularly the rotation axis B1) is longer than the width W32 of the opening 32. Therefore, even if the adapter 2 is rotated at any angle about the rotation axis B1, it is difficult to remove the adapter 2 from the wiring duct 31. Consequently, it is difficult to remove the adapter 2 from the front of the wiring duct 31. This further reduces the chances of the adapter 2 being removed from the front of the wiring duct 31. The same applies to the adapter 2 of the modified example.
[0116] Furthermore, the wiring conduit system 3 of this embodiment includes a wiring conduit 31, an end cap 5, and a detachable cover 6. In particular, the wiring conduit system 3, by including the detachable cover 6, easily secures the workspace 42 required for attaching and detaching the adapter 2. Therefore, even when the wiring conduit 31 is embedded in the base 4, the adapter 2 can be easily attached and detached from the wiring conduit 31. Furthermore, since the detachable cover 6 closes the workspace 42 before and after attaching and detaching the adapter 2, the aesthetics are preserved.
[0117] The length L6 of the disassembly cover 6 is longer than the length L5 of the end cap 5 and the length of a portion (in this embodiment, the mounting protrusion 26) of the adapter 2. Therefore, as the working space 42, the space required for the assembly and disassembly of the adapter 2 can be ensured.
[0118] Again, even if the movement in the up-down direction and the left-right direction is restricted, the detachable cover 6 can also slide in the front-back direction. Therefore, even if the detachable cover 6 is embedded in the base 4, the detachable cover 6 can be easily detached.
[0119] In addition, the end cap 5 is mounted on the wiring duct 31 using a dedicated tool. Therefore, even if the detachable cover 6 is removed, the adapter 2 can be suppressed from being pulled out of the wiring duct 31.
[0120] Furthermore, because the daily appliance 1 of this embodiment includes the adapter 2 of this embodiment and the wiring conduit system 3 of this embodiment, it is possible to prevent the adapter 2 from being pulled out of the wiring conduit 31. Furthermore, even if the wiring conduit 31 is embedded in the base 4, the adapter 2 can be easily attached to and detached from the wiring conduit 31. Furthermore, while the adapter 2 of the reference example is easier to pull out than the adapter 2 of the present embodiment and the modified examples, the daily appliance 1 can also include the adapter 2 of the reference example.
[0121] Furthermore, in the daily use tool 1 of this embodiment, the wiring conduit 31, the end cap 5, and the detachable cover 6 are embedded in the base 4. By removing the detachable cover 6, a workspace 42 is created. Furthermore, the end cap 5 can also be removed using the workspace 42. Therefore, even without removing the wiring conduit 31 from the base 4, the adapter 2 can be easily attached to and detached from the wiring conduit 31.
