(Embodiment)
(1) Configuration The cover mechanism 10 and the switch device 100 according to the present embodiment will be described in detail with reference to FIGS. In the following description, each direction is defined as indicated by arrows “up”, “down”, “left”, “right”, “front”, “back” in FIG. However, these directions are not intended to define the directions when the cover mechanism 10 and the switch device 100 are used. In addition, the arrows indicating the directions in the drawings are merely shown for explanation, and do not accompany the substance.

(1.1) Description of Cover Mechanism As shown in FIGS. 1 to 3, the cover mechanism 10 includes a frame body 20, a cover member 30, and a support mechanism 40. The cover mechanism 10 of this embodiment is used for the switch 200 attached to a construction surface such as a wall.

  The frame body 20 is a molded product of synthetic resin such as ABS resin. The frame body 20 includes a front plate 21 and side plates 22. The front plate 21 has a rectangular shape when viewed from the front. The side plate 22 protrudes rearward from the entire circumference of the outer peripheral edge of the rear surface of the front plate 21. An opening 23 is provided in the center of the front plate 21. The opening 23 penetrates the front plate 21 in the front-rear direction. The opening 23 is a rectangular hole provided so that the longitudinal direction is parallel to the vertical direction. In the present embodiment, the entire opening 23 is a target portion covered by the cover member 30.

  A pair of projections 24 (second projecting portions) project upward from the side plate 22 at the top of the frame body 20. One pair of protrusions 24 is provided on each side of the upper side plate 22 in the left-right direction. The front plate 21 of the frame body 20 is provided with a hole 25 that penetrates the front plate 21 in the front-rear direction under each of the pair of protrusions 24. The hole 25 is a hole elongated in the left-right direction. The upper portion of the hole 25 in the upper side plate 22 is a flexible portion 26. The flexible portion 26 can be deformed in the vertical direction, and a protrusion 24 is provided on the upper surface of the flexible portion 26. A pair of hooking holes 27 are provided in the lower part of the front plate 21. A pair of hooking holes 27 is provided on each of the left and right sides of the front plate 21.

  The cover member 30 is a molded product of a transparent synthetic resin (acrylic resin, polycarbonate resin, etc.) having translucency, for example. The upper part of the cover member 30 is rotatably supported by the frame body 20 by the support mechanism 40. A pair of hooks 31 (see FIG. 2B) are provided at the lower part of the rear surface of the cover member 30. The pair of hooks 31 protrude rearward from portions corresponding to the pair of hook holes 27 on the rear surface of the cover member 30. The cover member 30 has a cover portion 32 that is positioned in front of the support mechanism 40 in a state in which the cover member 30 is closed and covers the support mechanism 40. In the present embodiment, the cover 32 is an upper portion of the cover member 30 and is configured by a portion located in front of the support mechanism 40. Since the cover portion 32 of the cover member 30 covers the support mechanism 40, the difference in appearance from the case where the cover mechanism 10 is not provided is less noticeable. When the cover mechanism 10 is attached to the wiring device, the difference in appearance between the wiring device to which the cover mechanism 10 is attached and the wiring device to which the cover mechanism 10 is not attached is less noticeable, and the appearance is made uniform. be able to.

  In the present embodiment, the width of the cover member 30 in the left-right direction is larger than the width of the frame body 20 in the left-right direction. Therefore, in the state where the cover member 30 is closed, both end portions in the left-right direction of the cover member 30 protrude outward from the frame body 20. As a result, the user can easily grasp the left and right ends of the cover member 30 and easily perform an operation of opening the cover member 30.

  The support mechanism 40 is disposed on the side of the frame body 20. The support mechanism 40 supports the cover member 30 so that the cover member 30 can rotate between the first position and the second position about the rotation axis. Here, the first position is a position where the cover member 30 is disposed on the front side of the frame body 20 and the cover member 30 covers the opening 23 (target portion). The second position is a position where the cover member 30 does not cover the opening 23.

  The support mechanism 40 includes a shaft body 50, a shaft support portion 60 provided on the frame body 20, and a pair of bearing portions 70 provided on the cover member 30.

  The shaft body 50 is a metal round bar that serves as a rotating shaft. On the outer peripheral surface of the shaft body 50, a recess 51 is formed over the entire circumference in the central portion of the shaft body 50 in the axial direction. Since the shaft body 50 is separate from the resin frame main body 20 and the cover member 30, the material of the shaft body 50 can be made of metal, and the shaft body 50 can be formed as compared with the case where the shaft body 50 is formed of resin. 50 can be made small.

  The shaft support portion 60 has a cylindrical portion 61 whose left-right direction is the central axis direction. The horizontal width of the cylindrical portion 61 is smaller than the horizontal width of the frame body 20. The cylindrical portion 61 is provided at the center of the frame body 20 in the left-right direction. A part of the peripheral surface of the cylindrical portion 61 is connected to the upper side plate 22 of the frame body 20. That is, the cylindrical portion 61 is provided so as to protrude laterally from the upper side plate 22 of the frame body 20. Note that an opening 62 is provided at the rear portion of the cylindrical portion 61 at the center in the left-right direction.

  The shaft body 50 is inserted into the insertion hole 63 at the center of the cylindrical portion 61. On the inner peripheral surface of the cylindrical portion 61, a protrusion 64 to be inserted into the recess 51 is provided at a portion corresponding to the recess 51 of the shaft body 50 in a state where the shaft body 50 is inserted into the insertion hole 63. The shaft body 50 is positioned in the cylindrical portion 61 by inserting the protrusion 64 into the recess 51. Since the horizontal width of the cylindrical portion 61 is shorter than the total length of the shaft body 50, both ends of the shaft body 50 are exposed to the outside of the cylindrical portion 61 in a state where the shaft body 50 is inserted into the insertion hole 63 of the cylindrical portion 61. doing.

  In the cover mechanism 10 of this embodiment, the direction in which the shaft body 50 is inserted into the insertion hole 63 is determined when the cover mechanism 10 is assembled. For example, the shaft body 50 is inserted into the insertion hole 63 from the right side. An inclined surface 642 (see FIG. 4) is formed at the right corner of the two left and right corners of the protrusion 64. The inclined surface 642 is an inclined surface in which the amount of protrusion from the inner peripheral surface of the cylindrical portion 61 increases toward the left side. When the shaft body 50 is inserted into the insertion hole 63 from the right side, the shaft body 50 comes into contact with the inclined surface 642 of the protrusion 64 so that the shaft body 50 can easily ride on the protrusion 64. Of the two corners of the protrusion 64 in the left-right direction, the left corner 641 is a right-angle corner. Therefore, when the projection 64 is inserted into the recess 51, the side surface of the corner portion 641 hits the side surface of the recess 51, thereby restricting the rightward movement of the shaft body 50.

  Further, the shaft support portion 60 has a plurality of convex portions 631 that protrude from the inner peripheral surface of the insertion hole 63 of the cylindrical portion 61 (see FIG. 5). The plurality of convex portions 631 are provided at regular intervals in the circumferential direction on the inner peripheral surface of the insertion hole 63. When the shaft body 50 is inserted into the insertion hole 63 of the cylindrical portion 61, the projection 631 hits against the metal shaft body 50 and is crushed, so that the shaft body 50 can be rotated in a state where the backlash of the shaft body 50 is reduced. It is supported by the support part 60. In order to reduce rattling of the shaft body 50, the shaft body 50 may be knurled. However, the knurling process is expensive. In the present embodiment, by forming the convex portion 631 on the inner peripheral surface of the insertion hole 63, the backlash of the shaft body 50 is reduced, and the configuration for reducing the backlash of the shaft body 50 can be realized at low cost.

  The pair of bearing portions 70 are provided on the upper part of the rear surface of the cover member 30. The pair of bearing portions 70 are provided so as to be positioned one by one on the left and right of the shaft support portion 60 of the frame body 20. Each of the pair of bearing portions 70 has a pair of side walls 71 and 72 and a bearing piece 73. The pair of side walls 71 and 72 are provided along the axial direction of the shaft body 50, and are disposed on both sides of the shaft body 50. The bearing piece 73 is provided between the outer end portions of the side walls 71 and 72 (the end portion on the opposite side of the shaft support portion 60 in the axial direction of the shaft body 50). The bearing piece 73 has an insertion hole 74 into which the shaft body 50 is inserted. Of the side walls 71, 72, the side wall 71 close to the outer peripheral edge of the cover member 30 has a larger rearward protrusion than the side wall 72. In the present embodiment, the side wall 71 becomes the first protrusion. Further, a protruding piece 33 for preventing the shaft body 50 from coming off is provided at the left end of the rear surface of the cover member 30. The protruding piece 33 is provided at a position facing the bearing piece 73 of the bearing portion 70 on the left side of the cover member 30. The protruding piece 33 is provided at a position where the shaft body 50 protruding from the insertion hole 74 of the bearing piece 73 hits.

  In the present embodiment, when the left-right direction, which is the axial direction of the shaft body 50 serving as the rotation axis, is the first direction, and the up-down direction orthogonal to the first direction is the second direction, the support mechanism 40 and the frame body 20 are They are arranged side by side in two directions. Note that the front-rear direction orthogonal to the first direction and the second direction is referred to as a third direction.

  The cover mechanism 10 is assembled as follows. In addition, the assembly procedure demonstrated below is an example, and can be changed suitably.

  The operator inserts the shaft body 50 into the insertion hole 74 of the bearing piece 73 of the right bearing portion 70 in a state where the cover member 30 is overlapped on the front side of the frame body 20. The operator pushes the shaft body 50 to the left, and inserts the shaft body 50 into the insertion hole 63 of the shaft support portion 60 and the insertion hole 74 of the left bearing portion 70. As a result, the cover member 30 is attached to the frame main body 20 so as to be rotatable about the shaft body 50.

  When the shaft body 50 is inserted to a predetermined position, the protrusion 64 of the shaft support portion 60 is inserted into the recess 51 of the shaft body 50, and the position of the shaft body 50 is positioned at a predetermined position in the left-right direction.

  Moreover, since the corner | angular part 641 of the processus | protrusion 64 contacts the side surface of the recessed part 51, since the shaft body 50 becomes difficult to move to the right side, the shaft body 50 becomes difficult to remove | deviate.

  Further, when the shaft body 50 is inserted into the insertion hole 63 of the shaft support portion 60, the convex portion 631 provided on the inner peripheral surface of the insertion hole 63 is crushed by the shaft body 50. The shaft body 50 is supported by the shaft support portion 60 in a reduced state.

  In a state where the cover member 30 is overlapped with the front side of the frame body 20, the hook 31 of the cover member 30 is inserted into the hook hole 27 of the frame body 20. In this state, the claw at the tip of the hook 31 is hooked on the peripheral edge of the hook hole 27 on the rear surface of the frame main body 20, so that the cover member 30 is kept closed.

  The operation unit 220 is formed in a rectangular plate shape having a larger area than the front surface of the switch body 210. In the present embodiment, the operation unit 220 is formed to have substantially the same size as the opening 23 of the frame body 20, and the operation unit 220 is disposed in the opening 23.

  The operation unit 220 is attached to the switch body 210 so as to be rotatable around a shaft part on the left side of the switch body 210. When the right side of the operation unit 220 is pressed, the operation unit 220 rotates and the push button is pressed on the back surface of the operation unit 220. When the push button is pushed by the operation unit 220, the opening / closing mechanism of the switch body 210 switches the contact on / off.

  The operation unit 220 may be attached to the switch main body 210 so as to be rotatable around a shaft portion at the center of the switch main body 210 in the left-right direction. In this case, one of the left and right end portions of the operation unit 220 protrudes forward. When one of the left and right ends of the operation unit 220 protruding forward is pushed rearward, the operation unit 220 rotates, and the opening / closing mechanism switches on / off of the contact according to the rotation of the operation unit 220.

  The switch 200 is attached to the attachment frame 300. The attachment frame 300 is made of synthetic resin or metal, and holds the switch 200 and is attached to a construction surface such as a wall. The attachment frame 300 is used for attaching an embedding wiring device such as the switch 200 to the construction surface. A maximum of three wiring devices can be attached to the attachment frame 300. The upper and lower frame pieces 301 of the attachment frame 300 are provided with a through hole 302 into which a fixing screw is inserted and a screw hole 303, respectively.

  The attachment frame 300 is attached to the switch box embedded in the wall in a state where the upper and lower frame pieces 301 are in contact with the periphery of the embedding hole provided in the wall. That is, the fixing frame 300 is screwed to the switch box by attaching the fixing screw inserted into the through hole 302 of the frame piece 301 to the screw hole of the switch box. That is, the attachment frame 300 is fixed to the wall.

  The plate frame 400 is attached to the front surface of the attachment frame 300. The plate frame 400 is a molded product of synthetic resin and is formed in a rectangular frame shape. The plate frame 400 has a rectangular frame shape having a pair of horizontal frame portions 401 and a pair of vertical frame portions 402. The plate frame 400 has a rectangular window hole 403 in the center. Each of the pair of horizontal frame portions 401 is provided with a screw insertion hole 404 through which the fixing screw 410 is passed. Each of the pair of vertical frame portions 402 is provided with three attachment holes 405 that penetrate the vertical frame portion 402 in the front-rear direction. The three attachment holes 405 are provided in the middle part and both side parts in the vertical direction of the vertical frame part 402.

  The plate frame 400 is attached to the attachment frame 300 as follows. With the plate frame 400 superimposed on the front surface of the mounting frame 300, the fixing screw 410 inserted into the screw insertion hole 404 is attached to the screw hole 303 of the mounting frame 300, so that the plate frame 400 is attached to the front surface of the mounting frame 300. Attached to.

  The cover mechanism 10 according to this embodiment is attached to the front side of the plate frame 400. A hooking portion 28 (see FIG. 7) to be inserted into the mounting hole 405 of the plate frame 400 is provided on the back surface of the frame body 20. When the frame main body 20 is overlapped on the front side of the plate frame 400, the hooking portion 28 of the frame main body 20 is inserted into the mounting hole 405 of the plate frame 400, and the hooking portion 28 is hooked on the peripheral portion of the mounting hole 405. 20 is attached to the plate frame 400. When the cover mechanism 10 is attached to the plate frame 400, the operation unit 220 of the switch 200 held by the attachment frame 300 is disposed in the opening 23 of the frame body 20.

(2) Operation Description FIG. 2A is a front view of the cover mechanism 10 in a state where the cover member 30 is closed. The position of the cover member 30 shown in FIG. 2A is the first position. When the cover member 30 is in the first position, the cover member 30 covers the opening 23 of the frame body 20. Therefore, in this state, the operation unit 220 disposed in the opening 23 is covered with the cover member 30, and the operation unit 220 cannot be operated. Since the portion of the cover member 30 located on the front side of the opening 23 is transparent, the user can see the operation unit 220 through the cover member 30.

  When the user wants to operate the operation unit 220, first, an operation of opening the cover member 30 is performed. That is, from a state in which the cover member 30 is closed, the user rotates the cover member 30 in a direction (in the direction of arrow D1 in FIG. 6A) that holds both sides of the cover member 30 in the left-right direction and opens the cover member 30. . When the cover member 30 rotates from the first position in the direction of the arrow D1 to a predetermined position (position shown in FIG. 6A), the tip portion of the side wall 71 that is the first protruding portion comes into contact with the protrusion 24 of the frame body 20. When the user further rotates the cover member 30 from the position of FIG. 6A in the direction of the arrow D1, the projection 24 is pushed by the tip portion of the side wall 71, and the flexible portion 26 is deformed, so that the projection 24 becomes the side wall 71. It is moved in the direction away from the tip portion of. Thereby, the front-end | tip part of the side wall 71 can get over the protrusion 24, and the cover member 30 further rotates in the direction of arrow D1 (refer FIG. 6B). When the front end portion of the side wall 71 gets over the protrusion 24 and moves forward of the protrusion 24, the front end portion of the side wall 71 is hooked on the protrusion 24, so that the cover member 30 is held open. Here, the position of the cover member 30 illustrated in FIG. 6B is an example of a second position where the cover member 30 does not cover the opening 23 (target portion).

  In the state where the cover member 30 is located at the second position, as shown in FIG. 2B, the opening 23 of the frame main body 20 is not covered by the cover member 30, so that the user operates the operation unit 220. Can do.

  When the user closes the cover member 30, the user covers the cover member 30 from the opened state in the direction in which the user holds the cover member 30 and closes the cover member 30 (the direction of arrow D <b> 2 in FIG. 6B). The member 30 is rotated. When the cover member 30 tries to rotate in the direction of the arrow D 2, the distal end portion of the side wall 71, which is the first protrusion, pushes the projection 24 of the frame body 20, and the flexible portion 26 is deformed. Move away from the tip. As a result, the front end portion of the side wall 71 can get over the protrusion 24, the cover member 30 further rotates in the direction of the arrow D <b> 2, and the cover member 30 moves to a position overlapping the front surface of the frame body 20. At this time, the hooking hook 31 of the cover member 30 is inserted into the hooking hole 27 of the frame main body 20, and the hooking hook 31 is hooked on the peripheral portion of the hooking hole 27, whereby the cover member 30 is held in the first position.

  Here, the switch 200 is a switch for turning on or off a ventilation fan of a 24-hour ventilation system, for example. It is necessary to operate the ventilation fan of the 24-hour ventilation system at all times. Therefore, the cover member 30 normally covers the operation unit 220 of the switch 200 so that the operation of turning off the ventilation fan using the switch 200 is not performed carelessly. Accordingly, it is possible to reduce a possibility that the operation unit 220 is operated unintentionally due to a person or an object colliding with the operation unit 220. Further, when the user operates the switch 200, the user only has to open the cover member 30, and the switch 200 can be operated if necessary. In addition, since the cover member 30 of this embodiment is hold | maintained in the open state, there also exists an advantage that the operation part 220 is easy to operate.

(3) Effects The cover mechanism 10 of the present embodiment includes a frame body 20 having an opening 23, a cover member 30 attached to the frame body 20, and a support that supports the cover member 30 so as to be rotatable with respect to the frame body 20. And a mechanism 40. The support mechanism 40 is disposed on the side of the frame body 20. The support mechanism 40 supports the cover member 30 so that the cover member 30 can rotate between the first position and the second position about the rotation shaft (shaft body 50). The first position is a position where the cover member 30 covers the target portion that is at least a part of the opening 23. The second position is a position where the cover member 30 does not cover the target portion. The cover member 30 has a cover portion 32 that is positioned in front of the support mechanism 40 and covers the support mechanism 40 in a state where the cover member 30 is located at the first position.

  Since the support mechanism 40 is located on the side of the frame body 20, the thickness of the cover mechanism 10 in the front-rear direction can be reduced as compared with the case where the support mechanism 40 is provided on the front side of the frame body 20.

  In the cover mechanism 10 of the present embodiment, the support mechanism 40 is provided on the shaft body 50 serving as the rotation shaft, the shaft main body 60 that is provided on the frame body 20 and supports the shaft body 50, and the cover member 30. And a bearing portion 70 that supports the shaft body 50 in a rotatable state.

  In the cover mechanism 10, the shaft body 50 supported by the shaft support portion 60 of the frame body 20 is rotatably supported by the bearing portion 70 of the cover member 30. Therefore, the material of the shaft body 50 can be a material (for example, a metal material) different from the frame body 20 and the cover member 30. This configuration is not an essential configuration for the cover mechanism 10 and can be omitted as appropriate. Further, this configuration can be appropriately combined with other configurations and modifications of the embodiment.

  In the cover mechanism 10 of the present embodiment, a first protrusion (side wall 21) that protrudes from the surface of the cover member 30 may be provided on the surface of the cover member 30. The frame main body 20 may be provided with a second protrusion (protrusion 24) and a flexible part (flexible part 26). The second protrusion (protrusion 24) is located on a locus along which the first protrusion (side wall 21) moves while the cover member 30 rotates between the first position and the second position.

(4) Modifications Below, cover mechanisms and switch devices according to modifications of the above embodiment are listed. In addition, each structure of the modified example demonstrated below is applicable in combination with each structure demonstrated in the said embodiment suitably.

(4.1) Modification 1
A cover mechanism 10A according to Modification 1 will be described with reference to FIGS. Hereinafter, only the characteristic part of the first modification will be described. The “cover mechanism 10A”, “frame body 20A”, “cover member 30A”, “support mechanism 40A”, and “shaft support portion 60A” of Modification 1 are the “cover mechanism 10” and “frame body” of the embodiment, respectively. 20 ”,“ cover member 30 ”,“ support mechanism 40 ”, and“ shaft support portion 60 ”.

  In the cover mechanism 10A of Modification 1, a protrusion 65 (second protrusion) is provided on the surface of the cylinder part 61 provided in the frame body 20A. In addition, a gap 66 is provided between the inner peripheral surface of the cylindrical portion 61 and the shaft body 50 at a portion corresponding to the protrusion 65.

  On the other hand, a protruding portion 35 (first protruding portion) protruding rearward is provided between the left and right bearing portions 70 at the upper end portion of the rear surface of the cover member 30A. The protrusion 35 is located on a locus along which the protrusion 65 moves while the cover member 30 rotates between the first position and the second position.

  Therefore, when the projection 65 is pushed by the projection 35 of the cover member 30 according to the rotation of the cover member 30, the cylindrical portion provided with the projection 65 so that the projection 65 moves in a direction away from the projection 35. 61 part is deformed. That is, the part of the cylinder part 61 provided with the protrusion 65 becomes a flexible part. The cover member 30A is provided with a recess 34 into which the protrusion 65 enters in the state where the cover member 30A is opened.

  The operation of the cover mechanism 10A according to Modification 1 will be described.

  In a state where the cover member 30A overlaps the front side of the frame body 20A, that is, in a state where the cover member 30A is in the first position, the opening 23 of the frame body 20A is covered by the cover member 30A. Therefore, in this state, the operation unit 220 disposed in the opening 23 is covered with the cover member 30A, and the operation unit 220 cannot be operated.

  When the user wants to operate the operation unit 220, first, an operation of opening the cover member 30A is performed. That is, from the state in which the cover member 30A is closed, the user holds both sides of the cover member 30A in the left-right direction, and opens the cover member 30A (in the direction of arrow D1 in FIG. 8A) with the shaft body 50 as the center. The cover member 30A is rotated. When the cover member 30A rotates from the first position to a predetermined position (position shown in FIG. 8A) in the direction of the arrow D1, the tip portion of the protruding portion 35 contacts the protrusion 65 of the frame body 20A. When the user further rotates the cover member 30 in the direction of the arrow D1 from the position of FIG. 8A, the projection 65 is pushed by the tip portion of the projecting portion 35, and the cylindrical portion 65 that becomes the flexible portion is deformed. The protrusion 65 is moved away from the protrusion 35. Thereby, the front-end | tip part of the protrusion part 35 can get over the processus | protrusion 65, and the cover member 30A further rotates in the direction of arrow D1 (refer FIG. 8B). Then, when the tip portion of the protrusion 35 gets over the protrusion 65 and the cover member 30A further rotates in the direction of the arrow D1, the protrusion 65 is inserted into the recess 34 on the back surface of the cover member 30A, so that the cover member 30A is Held open. Here, the position of the cover member 30A illustrated in FIG. 8B is an example of a second position where the cover member 30A does not cover the opening 23 (target portion).
