Description

[Technical Field]

[0001] The present disclosure relates to a plug for a wiring duct. [Background technology]

[0002] Electrical appliances are sometimes installed on ceiling surfaces. Spotlights, for example, are well-known examples of such electrical appliances. These electrical appliances are sometimes attached to wiring ducts. A wiring duct is a tubular member installed on a ceiling surface. Electrical wires are arranged inside the wiring duct. Wiring ducts make it possible to organize a large number of electrical wires. Furthermore, wiring ducts make it easy to attach and detach spotlights, for example. This allows for flexible changes to the lighting layout, etc.

[0003] An electrical appliance to be attached to a wiring duct has a wiring duct plug that is attached to the wiring duct. For example, the wiring duct plug disclosed in Patent Document 1 has a first attachment part that rotates to be attached to the wiring duct, and a second attachment part that rotates in conjunction with the first attachment part to be attached to the wiring duct. The first attachment part has an electrical connection part that contacts the conductor of the wiring duct, and an operating part. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-307213 Summary of the Invention [Problem to be solved by the invention]

[0005] In addition to lighting fixtures, electrical appliances such as speakers that are part of sound equipment and air purifiers that are part of air conditioning equipment may be attached to wiring ducts. These electrical appliances may be larger than spotlights. Large lighting fixtures may also be attached to wiring ducts. When attaching large electrical appliances to wiring ducts, the mounting parts that are attached to the wiring duct will also be large. In this case, a great deal of force is required to attach the mounting parts to the wiring duct.

[0006] For example, in the wiring duct plug disclosed in Patent Document 1, an operating tool is provided only on the first attachment portion. In this configuration, the operating tool is operated by pinching it with fingers. In this case, it is difficult to apply a large force to the operating tool. Therefore, when a large electrical appliance is to be attached to the wiring duct, it is not easy to attach the attachment portion to the wiring duct.

[0007] Therefore, an object of the present disclosure is to provide a plug for a wiring duct that allows large electrical appliances to be easily attached to a wiring duct. [Means for solving the problem]

[0008] The wiring duct plug of the present disclosure is a wiring duct plug that is provided in an electrical appliance and attached to a wiring duct, and has a first rotating body having a first engagement portion that rotates to engage with the wiring duct, and a second rotating body that moves in conjunction with the first rotating body and has a second engagement portion that rotates to engage with the wiring duct, wherein the first rotating body has an electrical connection portion that contacts the conductor of the wiring duct and a first operating portion that protrudes to one side, and the second rotating body has a second operating portion that protrudes to one side. [Effects of the Invention]

[0009] The wiring duct plug of the present disclosure allows large electrical appliances to be easily attached to the wiring duct. [Brief explanation of the drawings]

[0011] An example of an embodiment of the present disclosure will be described in detail below. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating understanding of the present disclosure, and can be appropriately changed according to the application, purpose, specifications, etc.

[0012] [Electrical appliances] A spotlight 100 as an electrical appliance according to an embodiment will be described with reference to FIG.

[0013] The spotlight 100, which is an electrical appliance, is installed on the ceiling surface. More specifically, the spotlight 100 is attached to a wiring duct 110. The wiring duct 110 is arranged on the ceiling surface. The wiring duct 110 will be described in detail later. The spotlight 100 is a lighting appliance that irradiates light at a predetermined point. The spotlight 100 can change the direction or angle of the light. This allows the desired location to be illuminated more brightly. The spotlight 100 can be easily attached to or detached from the wiring duct 110. This allows the lighting layout, etc. to be freely changed.

[0014] It should be noted that the electrical appliance of the present disclosure is not limited to the spotlight 100. The electrical appliance of the present disclosure may be any electrical appliance that can be attached to or detached from the wiring duct 110. For example, the electrical appliance of the present disclosure may be a speaker that is part of an audio system, an air purifier that is part of an air conditioning system, or the like.

[0015] The spotlight 100 as an electrical appliance has a light source 101, a socket (not shown), an appliance body 102, an arm 103, and a wiring duct plug 10, the details of which will be described later. The light source 101 is attached to the socket. The socket is housed in the appliance body 102. The appliance body 102 is rotatably supported by the arm 103. The arm 103 is rotatably supported by the wiring duct plug 10. In other words, the wiring duct plug 10 is one of the components of the spotlight 100.

[0016] In the following description, the direction along the wiring duct 110 may be referred to as the depth direction (X direction in the drawings). Also, the direction perpendicular to the depth direction in the horizontal plane may be referred to as the width direction (Y direction in the drawings). Furthermore, the vertical direction perpendicular to the depth direction and width direction may be referred to as the up-down direction (Z direction in the drawings).

[0017] [Wiring Duct] The wiring duct 110 according to the embodiment will be described with reference to FIG.

[0018] The wiring duct 110 is a tubular member disposed on the ceiling surface. Electric wires (power supply electrodes, which will be described later) are passed through the inside of the wiring duct 110. The wiring duct 110 allows a large number of electric wires to be organized. The spotlight 100 is attached to the wiring duct 110. More specifically, the wiring duct plug 10 of the spotlight 100 is attached to the wiring duct 110.

[0019] The wiring duct 110 is made of, for example, synthetic resin. The wiring duct 110 is formed so as to extend in the depth direction. When viewed in cross section perpendicular to the depth direction, the wiring duct 110 is formed in a substantially C-shape. A duct opening 111 is formed on the lower surface of the wiring duct 110. The duct opening 111 is formed along the depth direction. Flanges 112 are formed inward on both sides of the lower end of the wiring duct 110 in the width direction.

[0020] Two protrusions 113 are formed inside the wiring duct 110. The two protrusions 113 protrude from the middle in the up-down direction of two inner surfaces facing each other in the width direction of the wiring duct 110. A recess 114 is formed at the tip of each protrusion 113. A power supply electrode (not shown) is held inside the recess 114.

[0021] The power supply electrodes are a pair of electrodes that supply AC power to the spotlight 100. A power receiving terminal 35 of the first rotating body 30, which will be described later, is connected to the power supply electrodes. The power supply electrodes are made of a metal such as copper. In the wiring duct 110, grooves 115 are formed between the flange 112 and the protrusion 113, into which a first engagement portion 34 and a second engagement portion 44, which will be described later, are respectively engaged. The shape or size of the wiring duct 110 is not particularly limited.

[0022] [Wiring duct plug] The wiring duct plug 10 will be described with reference to FIGS.

[0023] The wiring duct plug 10 is one component of the spotlight 100. The wiring duct plug 10 is attached to a wiring duct 110. As will be described in detail later, the wiring duct plug 10 allows a large spotlight 100 to be easily attached to the wiring duct 110. Also, a large air purifier or speaker can be easily attached to the wiring duct 110.

[0024] The wiring duct plug 10 has a main body 20, a first rotating body 30, and a second rotating body 40, each of which will be described in detail later.

[0025] [Main unit] The main body 20 forms the outer shell of the wiring duct plug 10. The main body 20 is formed of, for example, synthetic resin. The main body 20 is hollow. The main body 20 is formed in a substantially cylindrical shape along the up-down direction. More specifically, the main body 20 is formed in a track shape (long hole shape) along the longitudinal direction when viewed in a cross section perpendicular to the up-down direction. Note that the main body of the present disclosure is not limited to a track shape along the longitudinal direction when viewed in a cross section perpendicular to the up-down direction. The main body of the present disclosure may be, for example, rectangular or square when viewed in a cross section perpendicular to the up-down direction.

[0026] A first rotating body 30 and a second rotating body 40 are rotatably supported on the top surface of the main body 20. A wall portion 21 is formed around the periphery of the top surface of the main body 20 except for a portion on one side in the width direction. In the portion of the periphery of the top surface of the main body 20 where the wall portion 21 is not formed, the first operating portion 32 of the first rotating body 30 and the second operating portion 42 of the second rotating body 40 protrude outside the main body 20. The first operating portion 32 and the second operating portion 42 are rotatable in the portion of the periphery of the top surface of the main body 20 where the wall portion 21 is not formed. In other words, the wall portion 21 restricts the rotation of the first operating portion 32 and the second operating portion 42.

[0027] The main body 20 supports the arm 103 so that it can rotate freely around an axis extending in the vertical direction. Inside the main body 20, a power line (not shown) is arranged, which is connected to the power receiving terminal 35 and is connected to a circuit board housed in the fixture main body 102.

[0028] [First body of revolution] The first rotating body 30 rotates and is attached to the wiring duct 110. The first rotating body 30 is electrically connected to the wiring duct 110. The first rotating body 30 is rotatably supported on the upper surface of the main body 20. The first rotating body 30 is disposed on one side in the depth direction of the upper surface of the main body 20. The first rotating body 30, except for the power receiving terminal 35, is formed of, for example, synthetic resin.

[0029] The first rotating body 30 has a first rotating portion 31, a first operating portion 32, a first gear portion 33, a first engaging portion 34, and a power receiving terminal 35 as an electrical connection portion, each of which will be described in detail below.

[0030] Hereinafter, the state in which the wiring duct plug 10 is attached to the wiring duct 110 may be described as an "engaged state." In the "engaged state," the first rotating body 30 and the second rotating body 40 are engaged with the wiring duct 110. More specifically, in the "engaged state," the first engaging portion 34 and the second engaging portion 44 are engaged with the groove portion 115 of the wiring duct 110. Also, in the "engaged state," the power receiving terminal 35 is engaged with the recessed portion 114 of the wiring duct 110.

[0031] Additionally, the position at which the first rotating body 30 or the second rotating body 40 engages with the wiring duct 110 may be referred to as the "engagement position." Furthermore, the rotational direction in which the first rotating body 30 or the second rotating body 40 attempts to engage with the wiring duct 110 may be referred to as the "engagement direction."

[0032] Hereinafter, the state in which the wiring duct plug 10 is removed from the wiring duct 110 may be described as the "released state." In the "released state," the first rotating body 30 and the second rotating body 40 are released from engagement with the wiring duct 110. More specifically, in the "released state," the first engaging portion 34 and the second engaging portion 44 are released from engagement with the groove portion 115 of the wiring duct 110. Also, in the "released state," the power receiving terminal 35 is released from engagement with the recessed portion 114 of the wiring duct 110.

[0033] In addition, the position where the first rotating body 30 or the second rotating body 40 is released from the wiring duct 110 may be described as the "release position." Furthermore, the rotation direction in which the first rotating body 30 or the second rotating body 40 attempts to be released from the wiring duct 110 may be described as the "release direction."

[0034] The first rotating part 31 is a base part of the first rotating body 30. The first rotating part 31 is formed in a substantially disk shape. The first rotating part 31 is arranged on one side in the depth direction of the top surface of the main body 20. The first rotating part 31 is also arranged close to the second rotating part 41. A first operating part 32 is formed on one side in the width direction of the first rotating part 31. A first gear part 33 is formed on a part of the side surface of the first rotating part 31.

[0035] The first operating part 32 is a part that is rotated. The first operating part 32 and the second operating part 42 make it easier to apply a large force during rotation, as will be described in detail later. The first operating part 32 is formed in a strip shape. The first operating part 32 is formed on one side in the width direction of the first rotating part 31. The first operating part 32 also protrudes on one side in the width direction. A first locking part 32A that protrudes downward is formed on the tip side of the first operating part 32.

[0036] When the first operating part 32 rotates in the engagement direction, the first locking part 32A locks onto the side surface of the main body 20. At this time, rotation of the first operating part 32 in the engagement direction is restricted. In other words, when the first rotating body 30 is in the engagement position, the first locking part 32A of the first operating part 32 locks onto the side surface of the main body 20. Furthermore, when the first operating part 32 rotates in the release direction, the first operating part 32 is locked by the wall part 21 of the main body 20. In other words, when the first rotating body 30 is in the release position, the first operating part 32 locks onto the wall part 21 of the main body 20. The first operating part 32 is positioned lower than the second operating part 42. This allows the first operating part 32 to intersect with the second operating part 42.

[0037] The first gear portion 33 transmits the rotation of the first rotating portion 31 to the second rotating portion 41. The first gear portion 33 enables the first rotating portion 31 and the second rotating portion 41 to move in conjunction with each other. The first gear portion 33 is meshed with the second gear portion 43. The first gear portion 33 is formed at a portion where the first rotating portion 31 contacts the second rotating portion 41 within the rotation range of the first rotating portion 31 from the engaged position to the disengaged position.

[0038] The first engagement portion 34 is a portion that engages with the groove portion 115 of the wiring duct 110. The first engagement portion 34 is formed in a strip shape. The first engagement portion 34 is provided above the first rotating portion 31. The first engagement portion 34 rotates together with the first rotating portion 31. When the first rotating body 30 is in an engaged state, the longitudinal direction of the first engagement portion 34 is parallel to the width direction. On the other hand, when the first rotating body 30 is in a released state, the longitudinal direction of the first engagement portion 34 is parallel to the depth direction.

[0039] The power receiving terminal 35, which serves as an electrical connection part, is electrically connected to the power feeding electrode of the wiring duct 110 when the first rotating body 30 is in the engaged state. The power receiving terminal 35 is provided above the first engagement part 34. The power receiving terminal 35 rotates together with the first engagement part 34 and the first rotating part 31. When the first rotating body 30 is in the engaged state, the longitudinal direction of the power receiving terminal 35 is parallel to the width direction. On the other hand, when the first rotating body 30 is in the released state, the longitudinal direction of the power receiving terminal 35 is parallel to the depth direction.

[0040] [Second body of revolution] The second rotating body 40 rotates and is attached to the wiring duct 110. The second rotating body 40 is rotatably supported on the upper surface of the main body 20. The second rotating body 40 is disposed on the other side in the depth direction of the upper surface of the main body 20. The second rotating body 40 is formed from, for example, synthetic resin.

[0041] The second rotating body 40 has a second rotating portion 41, a second operating portion 42, a second gear portion 43, and a second engaging portion 44, each of which will be described in detail later.

[0042] The second rotating part 41 is a base part of the second rotating body 40. The second rotating part 41 is formed in a substantially disk shape. The second rotating part 41 is arranged on the other side in the depth direction of the top surface of the main body 20. The second rotating part 41 is also arranged close to the first rotating part 31. A second operating part 42 is formed on one side in the width direction of the second rotating part 41. A second gear part 43 is formed on a part of the side surface of the second rotating part 41.

[0043] The second operating portion 42 is a portion that is rotated. The first operating portion 32 and the second operating portion 42 make it easier to apply a large force during rotation, as will be described in detail later. The second operating portion 42 is formed in a strip shape. The second operating portion 42 is formed on one side in the width direction of the second rotating portion 41. The second operating portion 42 also protrudes on one side in the width direction. A second locking portion 42A that protrudes downward is formed on the tip side of the second operating portion 42.

[0044] When the second operating part 42 rotates in the engagement direction, the second locking part 42A locks onto the side surface of the main body 20. At this time, rotation of the second operating part 42 in the engagement direction is restricted. In other words, when the second rotating body 40 is in the engagement position, the second locking part 42A of the second operating part 42 locks onto the side surface of the main body 20. Furthermore, when the second operating part 42 rotates in the release direction, the second operating part 42 is locked by the wall part 21 of the main body 20. In other words, when the second rotating body 40 is in the release position, the second operating part 42 locks onto the wall part 21 of the main body 20. The second operating part 42 is positioned higher than the first operating part 32. This allows the second operating part 42 to intersect with the first operating part 32.

[0045] The second gear portion 43 transmits the rotation of the second rotating portion 41 to the first rotating portion 31. The second gear portion 43 allows the first rotating portion 31 and the second rotating portion 41 to move in conjunction with each other. The second gear portion 43 is meshed with the first gear portion 31. The second gear portion 43 is formed at a portion where the second rotating portion 41 contacts the first rotating portion 31 in the rotation range of the second rotating portion 41 from the engaged position to the disengaged position.

[0046] The second engagement portion 44 is a portion that engages with the groove portion 115 of the wiring duct 110. The second engagement portion 44 is formed in a strip shape. The second engagement portion 44 is provided above the second rotating portion 41. The second engagement portion 44 rotates together with the second rotating portion 41. When the second rotating body 40 is in an engaged state, the longitudinal direction of the second engagement portion 44 is parallel to the width direction. On the other hand, when the second rotating body 40 is in a released state, the longitudinal direction of the second engagement portion 44 is parallel to the depth direction.

[0047] [Released state] The released state of the wiring duct plug 10 will be described with reference to FIG.

[0048] In the released state of the wiring duct plug 10, the longitudinal direction of the first engagement portion 34 of the first rotating body 30 and the longitudinal direction of the second engagement portion 44 of the second rotating body 40 are parallel to the depth direction. Here, the groove portion 115 of the wiring duct 110 is parallel to the depth direction. Therefore, the first engagement portion 34 and the second engagement portion 44 are disengaged from the groove portion 115.

[0049] Furthermore, when the wiring duct plug 10 is in the released state, the longitudinal direction of the power receiving terminal 35 of the first rotating body 30 is the depth direction. Here, the recess 114 of the wiring duct 110 is parallel to the depth direction. Therefore, the power receiving terminal 35 is disengaged from the recess 114. Furthermore, the first operating part 32 and the second operating part 42 are in an open state on one side in the width direction. The first operating part 32 is in a state in which it is tilted at approximately 45 degrees from the width direction to one side in the depth direction. The second operating part 42 is in a state in which it is tilted at approximately 45 degrees from the width direction to the other side in the depth direction.

[0050] [Engaged state] The engaged state of the wiring duct plug 10 will be described with reference to FIG.

[0051] When the wiring duct plug 10 is in the engaged state, the longitudinal direction of the first engagement portion 34 of the first rotating body 30 and the longitudinal direction of the second engagement portion 44 of the second rotating body 40 are parallel to the width direction. As a result, the first engagement portion 34 and the second engagement portion 44 engage with the groove portion 115 of the wiring duct 110.

[0052] Furthermore, when the wiring duct plug 10 is in the engaged state, the longitudinal direction of the power receiving terminal 35 of the first rotating body 30 is parallel to the width direction. As a result, the power receiving terminal 35 engages with the recess 114 of the wiring duct 110. Furthermore, the first operating part 32 and the second operating part 42 are closed and crossed on one side in the width direction. The first operating part 32 is inclined at approximately 45° from the width direction to the other side in the depth direction, for example. The second operating part 42 is inclined at approximately 45° from the width direction to one side in the depth direction, for example.

[0053] [Installation operation] When attaching the wiring duct plug 10 to the wiring duct 110, the first rotating body 30 and the second rotating body 40 are rotated in the engagement direction so that the wiring duct plug 10 changes from the released state shown in Fig. 5 to the engaged state shown in Fig. 6. At this time, the first operating part 32 and the second operating part 42 are operated simultaneously.

[0054] Furthermore, when attaching the wiring duct plug 10 to the wiring duct 110, the first operating portion 32 and the second operating portion 42 are closed (in the direction of the arrow in FIG. 5). This operation can be performed, for example, by pinching the first operating portion 32 and the second operating portion 42 between the thumb and index finger. Alternatively, the first operating portion 32 and the second operating portion 42 can be pinched between the fingers of both hands. This allows a large force to be applied when attaching the wiring duct plug 10 to the wiring duct 110.

[0055] [Removal action] When removing the wiring duct plug 10 from the wiring duct 110, the first rotating body 30 and the second rotating body 40 are rotated in the release direction so that the wiring duct plug 10 changes from the engaged state shown in Fig. 6 to the released state shown in Fig. 5. At this time, the first operating part 32 and the second operating part 42 are operated simultaneously.

[0056] Furthermore, when removing the wiring duct plug 10 from the wiring duct 110, the first operating portion 32 and the second operating portion 42 are opened (in the direction of the arrows in FIG. 6). In the first half of this operation, for example, the first operating portion 32 and the second operating portion 42 may be pinched between the thumb and index finger. Alternatively, the first operating portion 32 and the second operating portion 42 may be pinched between the fingers of both hands. This allows a large force to be applied when removing the wiring duct plug 10 from the wiring duct 110.
