Embodiments for Carrying Out the Invention

[0009] Hereinafter, each embodiment will be described in detail with reference to the accompanying drawings.

[0010] FIG. 1 is a perspective view showing an example of the operating device 1 according to this embodiment. FIG. 2 is a plan view schematically showing the back side of the operating device 1. FIG. 3 is a perspective view of the fitting 50 of the operating device 1. FIG. 4 is a perspective view showing the upper case 102 forming the device body 10 of the operating device 1. FIG. 5 is a perspective view showing an enlarged part of the back side of the lower case 103 forming the device body 10 of the operating device 1 (the part around the access recess 132).

[0011] In FIGS. 1 and the like, a right-handed three-axis coordinate system is shown. Hereinafter, in the Z direction, in the attached state of the operating device 1 (attached state to the wall body), it is the vertical direction, and the positive side of the Z direction is the lower side. Also, the Y direction is the direction perpendicular to the wall body, the positive side of the Y direction is also referred to as the front side, and the negative side of the Y direction is also referred to as the back side. Also, the X direction corresponds to the left-right direction.

[0012] The operating device 1 is fixed to a wall and used. The wall can be arbitrary, for example, the wall of a room in a residence or the like. The object to be operated by the operating device 1 can be arbitrary, for example, a household appliance such as an air conditioner, or an intercom or the like. The wall to which the operating device 1 is attached has a surface parallel to the XZ plane. The operating device 1 is attached to the wall in a manner that the negative Y direction faces the wall.

[0013] The operating device 1 includes a device main body 10 and a fitting 50.

[0014] The device main body 10 has a front surface portion 11, a side surface portion 12, and a back surface portion 13. The device main body 10 has various electronic components (not shown) inside, surrounded by the front surface portion 11, the side surface portion 12, and the back surface portion 13. The various electronic components may include various chips (such as a microcontroller) executed on a substrate. Note that the overall form of the device main body 10 can be arbitrary, but in this embodiment, as an example, it is rectangular.

[0015] An operation unit 110 operable by a user is provided on the front surface portion 11. The operation unit 110 may be formed by, for example, a touch panel. Also, the operation unit 110 may include a mechanical switch. In addition to the operation unit 110, a display unit (not shown) may be provided on the front surface portion 11. For example, the operation unit 110 may be formed by a touch panel type display.

[0016] The side surface portion 12 extends from the outer edge of the front surface portion 11 toward the wall. The side surface portion 12 is provided over the entire circumference of the outer edge of the front surface portion 11. The side surface portion 12 has an opening 120 on the lower side. The function of the opening 120 will be described later. The side surface portion 12 may be in a form that, except for the opening 120, does not substantially form a significant gap with the wall.

[0017] In this embodiment, the side surface portion 12 is formed by the upper case 102 shown in FIG. 4. In the example shown in FIG. 4, the upper case 102 is open on the positive side in the Y direction (front side) and supports the front surface portion 11 around the opening. Further, the upper case 102 is open on the negative side in the Y direction (rear side). And the upper case 102 forms the side surface portion 12 surrounding an internal space that is open on both sides in the Y direction.

[0018] The back surface portion 13 extends in the negative Y direction. That is, the back surface portion 13 extends to the side facing the fitting 50 (see FIG. 3). The operating device 1 is attached to the fitting 50 in such a manner that the fitting 50 is positioned between the wall body and the back surface portion 13.

[0019] In this embodiment, the back surface portion 13 is formed by the lower case 103. The lower case 103 is provided so as to cover the entire opening on the back side of the upper case 102. Note that the connection portion between the lower case 103 and the upper case 102 may be sealed by a sealing material 70 (see FIG. 12) over the entire outer peripheral portion.

[0020] As shown in FIGS. 2 and 5, the back surface portion 13 has a base portion 130, an access recess 132, a plate-like portion 134, a protruding portion 136, and a second engaging portion 138.

[0021] The base portion 130 extends around the access recess 132 when viewed in the Y direction and abuts on the fitting 50 in the Y direction. Note that the base portion 130 may have recesses, protrusions, etc. other than the engaging recess 1381 related to the access recess 132 and the second engaging portion 138.

[0022] The access recess 132 is recessed toward the front side in the Y direction with respect to the surface (in the XZ plane) in which the base portion 130 extends. The access recess 132 forms a space portion S1 (see FIG. 10A) around the first engaging portion 1341. The space portion S1 is a space portion into which a tool 80 (see FIG. 15) described later can be inserted. The depth of the access recess 132 (the offset amount in the Y direction with respect to the base portion 130) may be adapted within a range in which the tool 80 can be inserted.

[0023] The access recess 132 is not in communication with the interior of the apparatus main body 10. That is, through holes are not provided in the bottom wall portion 1321 or the side wall portion 1322 of the access recess 132. The access recess 132 communicates directly with the opening 120 of the side surface portion 12. That is, the lower end of the access recess 132 forms the opening 120.

[0024] The plate-like portion 134 extends in a manner overlapping the access recess 132 when viewed in the Y direction. The plate-like portion 134 extends in substantially the same plane (in the XZ plane) as the base portion 130. A first engaging portion 1341 is formed on the plate-like portion 134. The first engaging portion 1341 engages with the fitting 50 as will be described later with reference to FIGS. 11 and 12. The first engaging portion 1341 is, for example, in the form of claws protruding toward the back side in the Y direction as shown in FIG. 5. In the present embodiment, two first engaging portions 1341 are provided side by side in the X direction. In other embodiments, only one first engaging portion 1341 may be provided, or three or more first engaging portions 1341 may be provided.

[0025] The plate-like portion 134 is elastically deformable in the Y direction. That is, the plate-like portion 134 is supported so as to be elastically deformable in the Y direction with respect to the base portion 130 such that the first engaging portion 1341 can be displaced toward the front side in the Y direction with respect to the fitting 50. Specifically, the plate-like portion 134 is cantilever-supported by the base portion 130 in such a manner that the lower end portion is a free end.

[0026] In the present embodiment, as shown in FIGS. 2 and 5, the plate-like portion 134 is connected to the base portion 130 via two connecting portions 1344 spaced apart in the X direction in order to enhance the flexibility related to the elastic deformation in the Y direction. Thereby, the flexibility related to the elastic deformation in the Y direction can be enhanced as compared with the case where the plate-like portion 134 is connected to the base portion 130 over the entire width in the X direction. In this case, the connecting portion 1344 may be formed thinner than the basic portion of the plate-like portion 134. Thereby, the flexibility of the plate-like portion 134 related to the elastic deformation in the Y direction can be effectively enhanced.

[0027] In this embodiment, the first engaging portion 1341 is formed in the vicinity of the lower end of the plate-like portion 134 in the vertical direction. In this case, when the first engaging portion 1341 is provided on the upper end side of the plate-like portion 134, the displacement amount of the first engaging portion 1341 toward the front side in the Y direction when the elastic deformation of the plate-like portion 134 in the Y direction is the same can be efficiently increased.

[0028] The plate-like portion 134 preferably has an inclined surface 1349 that inclines toward the front side in the Y direction as it goes toward the lower end at the lower end. The inclined surface 1349 has a function of enhancing the workability of removing the apparatus main body 10 by a tool 80 (see FIG. 15) described later. The inclined surface 1349 may be formed over the entire length in the X direction. In this case, the range in the X direction of the place where the tool 80 is inserted during the operation of removing the apparatus main body 10 by the tool 80 described later is widened, and the workability becomes good.

[0029] The protruding portion 136 protrudes from the base portion 130 toward the back side in the Y direction. The protruding portion 136 may be inserted into a recess (not shown) formed in the wall body when the apparatus main body 10 is attached to the wall body. A connector for wiring (not shown) related to the electronic components in the operation device 1 may be held on the protruding portion 136. In this case, the connector may be electrically connected to the wiring for power supply from the wall body (for example, the wiring from a household power supply).

[0030] The second engaging portion 138 engages with the fitting 50. As will be described later with reference to FIG. 13, the second engaging portion 138 engages with the fitting 50 in a different manner from the above-described first engaging portion 1341, and in cooperation with the first engaging portion 1341, appropriately restricts the degree of freedom of the apparatus main body 10 with respect to the fitting 50.

[0031] In this embodiment, as an example, the second engaging portion 138 is provided at one location on the upper side of the base portion 130 and at one location on the lower side of the diagonal side thereof. However, in other embodiments, it may be provided at two locations on the left and right sides of the upper side and at two locations on the left and right sides of the lower side, or any one of these four locations may be omitted. By providing at least two diagonal locations out of the four locations on the left and right of the upper side and the left and right of the lower side, stable fixing by the engagement of the second engaging portion 138 can be achieved, and the reliability of the engagement state at the first engaging portion 1341 can be enhanced. Each of the second engaging portions 138 may have the same form. In this embodiment, one second engaging portion 138 has a bridge-shaped portion 1382 in the X direction on the opening side of the engaging concave portion 1381. In this case, the engaging concave portion 1381 is recessed toward the front side in the Y direction with respect to the plane (in the XZ plane) in which the base portion 130 extends, similar to the access concave portion 132. The engaging concave portion 1381 is not in communication with the inside of the apparatus main body 10. That is, through holes are not provided in the bottom wall portion and the side wall portion of the engaging concave portion 1381. The engaging concave portion 1381 is open on the back side in the Y direction above and below the bridge-shaped portion 1382.

[0032] The fitting 50 may be formed of, for example, sheet metal or the like. The fitting 50 is fixed to the wall body. For example, the fitting 50 may be fixed to the wall body by screws or the like screwed into the wall body. In the example shown in FIG. 3, the fitting 50 is provided with screw holes 59 at two locations on the left and right.

[0033] The fitting 50 has a first engaged portion 51, a second engaged portion 52, and a central hole 54.

[0034] The first engaged portion 51 is in the form of a through hole in the Y direction. The first engaging portion 1341 on the back surface portion 13 of the apparatus main body 10 engages with the first engaged portion 51. This engagement mode will be described later with reference to FIG. 11 and subsequent figures.

[0035] The second engaged part 52 is in the form of a claw that protrudes forward in the Y direction and then extends upward. The second engaged part 52 engages with the second engaging part 138 on the back surface part 13 of the apparatus main body 10. In the state where the apparatus main body 10 is attached to the fitting 50, the second engaged part 52 fits into the engaging concave part 1381 of the second engaging part 138, and displacement upward in the Y direction and the Z direction is restricted by the bridge-shaped part 1382 within the engaging concave part 1381 (see FIG. 13).

[0036] The protruding part 136 of the above-described apparatus main body 10 is inserted into the central hole 54.

[0037] Next, with reference to FIGS. 6 to 13, a method for attaching the apparatus main body 10 to the fitting 50 and the configuration of the apparatus main body 10 related thereto will be described.

[0038] FIGS. 6 to 9 are explanatory views of each stage of a method for attaching the apparatus main body 10 to the fitting 50. In FIGS. 6 to 9, it is assumed that the fitting 50 is already fixed to a wall body (not shown), and it is a perspective view seen from the wall body side. FIGS. 10A and 10B are explanatory views of the engaging mode of the first engaging part 1341. FIG. 10A shows the state before engagement, and FIG. 10B is a cross-sectional view (a cross-section by the YZ plane passing through the first engaging part 1341) showing the engaged state. FIG. 11 is a plan view seen from the back side of the operating device 1 in the attached state of the operating device 1 (the state where the apparatus main body 10 is completely attached to the fitting 50). FIG. 12 is a cross-sectional view taken along line A-A of FIG. 11, and FIG. 13 is a cross-sectional view taken along line B-B of FIG. 11. The wall body W is schematically shown in FIGS. 10A, 10B, 12, and 13.

[0039] In this mounting method, first, as shown in FIG. 6, the apparatus main body 10 is moved to the upper mounting start position with respect to the fitting 50 fixed to the wall body, and then, as indicated by the arrow R7 in FIG. 7, the apparatus main body 10 is moved toward the fitting 50 to the back side in the Y direction. At this time, the apparatus main body 10 maintains the relative positional relationship in which the second engaged portion 52 enters the engaging concave portion 1381 of the second engaging portion 138 with respect to the fitting 50, and the protruding portion 136 is inserted into the central hole 54, and the base portion 130 of the back surface portion 13 of the apparatus main body 10 is brought into contact with the fitting 50. It is assumed that a concave portion (not shown) capable of accommodating the protruding portion 136 is formed in the wall body.

[0040] Next, when the base portion 130 of the back surface portion 13 of the apparatus main body 10 comes into contact with the fitting 50, the apparatus main body 10 is slid downward (see the arrow R8 in FIGS. 8 and 10A). At this time, the apparatus main body 10 may be slid downward within the XZ plane.

[0041] By the way, in this embodiment, as described above, the first engaging portion 1341 protrudes from the plate-like portion 134 to the back side in the Y direction. Therefore, in a state where the base portion 130 of the back surface portion 13 of the apparatus main body 10 is in contact with the fitting 50, the plate-like portion 134 elastically deforms toward the front side in the Y direction (see the arrow R10 in FIG. 10A) because the first engaging portion 1341 receives a force from the fitting 50 toward the front side in the Y direction. In this way, the apparatus main body 10 is slid downward with respect to the fitting 50 in a state where the plate-like portion 134 is elastically deformed toward the front side in the Y direction (see FIG. 10A).

[0042] When the apparatus main body 10 is slid downward with respect to the fitting 50 (see the arrow R8 in FIGS. 8 and 10A) and the first engaging portion 1341 reaches the position of the first engaged portion 51, the plate-like portion 134 is displaced toward the back side in the Y direction (restored to the original shape) as indicated by the arrow R11 in FIG. 10B because the first engaging portion 1341 no longer receives a force from the fitting 50 toward the front side in the Y direction. Thereby, the engagement between the first engaging portion 1341 and the first engaged portion 51 is realized (see FIG. 9).

[0043] When the engagement between the first engaging portion 1341 and the first engaged portion 51 is realized in this way, the mounting state of the operating device 1 (the state where the device main body 10 is completely mounted on the fitting 50) is achieved. In this mounting state of the operating device 1, as shown in FIGS. 11 and 12, due to the engagement between the first engaging portion 1341 and the first engaged portion 51, the upward displacement of the device main body 10 with respect to the fitting 50 is restricted. That is, when an attempt is made to displace the device main body 10 upward with respect to the fitting 50, the device main body 10 receives a downward force F120 from the fitting 50 via the first engaging portion 1341, and the displacement is locked.

[0044] Also, in the mounting state of the operating device 1, as shown in FIG. 13, due to the engagement between the second engaging portion 138 and the second engaged portion 52, the downward displacement of the device main body 10 with respect to the fitting 50 and the displacement in the front side in the Y direction are restricted. That is, when an attempt is made to displace the device main body 10 downward with respect to the fitting 50, the device main body 10 receives an upward force F130 from the fitting 50 via the second engaging portion 138, and the displacement is locked. Also, when an attempt is made to displace the device main body 10 in the front side in the Y direction with respect to the fitting 50, the device main body 10 receives a force F140 in the back side in the Y direction from the fitting 50 via the second engaging portion 138, and the displacement is locked.

[0045] Note that in the mounting state of the operating device 1, the lateral displacement of the device main body 10 with respect to the fitting 50 may be restricted by the engagement between the second engaging portion 138 and the second engaged portion 52.

[0046] In this way, according to this embodiment, in the mounting state of the operating device 1, due to the engagement between the first engaging portion 1341 and the first engaged portion 51, the upward displacement (displacement in the removal direction) of the device main body 10 with respect to the fitting 50 is restricted. Thereby, easy detachment of the device main body 10 from the fitting 50 can be prevented. That is, according to this embodiment, the first engaged portion 51 that cannot be easily disengaged between the fitting 50 and the device main body 10 without tools can be realized.

[0047] Next, with reference to FIGS. 14 and 15, a method for removing the apparatus main body 10 from the fitting 50 and the configuration of the apparatus main body 10 related thereto will be described.

[0048] FIG. 14 is an explanatory view of a method for removing the apparatus main body 10 from the fitting 50, and is a plan view of the operating device 1 in the attached state viewed in the X direction. In FIG. 14, together with the wall body W, a removal tool 80 is schematically shown. FIG. 15 is an explanatory view of a method for removing the apparatus main body 10 from the fitting 50, and is a cross-sectional view taken along line C-C of FIG. 11.

[0049] In the present embodiment, as described above, due to the engagement between the first engaging portion 1341 and the first engaged portion 51, the operating device 1 in the attached state is substantially unable to be removed (removed from the fitting 50) without using the tool 80. On the other hand, in the present embodiment, as described below, the workability of removal using the tool 80 is good. The removal tool 80 preferably has a thin rod-shaped tip portion, and for example, a minus driver may be used.

[0050] In the present embodiment, as described above, the side surface portion 12 of the apparatus main body 10 has an opening 120 on the lower side while surrounding the internal space of the apparatus main body 10 over the entire circumference. The opening 120 communicates with the space portion S1 (the space portion S1 around the first engaged portion 51) as described above. Therefore, an operator performing the removal can access the space portion S1 through the opening 120 of the apparatus main body 10 with the operating device 1 in the attached state, as indicated by the arrow R14 in FIG. 14. That is, the operator can easily remove the apparatus main body 10 from the fitting 50 by inserting the tool 80 through the opening 120 of the operating device 1 (see the arrow R14 in FIG. 14 and the arrow R15 in FIG. 15).

[0051] Specifically, as shown on the left side of FIG. 15, the operator inserts the tool 80 through the opening 120 (see arrow R15), and directs the tip of the tool 80 toward the back side of the plate-like portion 134 in the Y direction. At this time, since the plate-like portion 134 has an inclined surface 1349 at its lower end, the tip of the tool 80 is easily guided along the inclined surface 1349 to the back side of the plate-like portion 134 in the Y direction. Also due to such an inclined surface 1349, the workability is improved.

[0052] Here, in this embodiment, as described above, the plate-like portion 134 is elastically deformable toward the front side in the Y direction.

[0053] Therefore, as shown on the right side of FIG. 15, when the operator inserts the tip of the tool 80 to the back side of the plate-like portion 134 in the Y direction (see arrow R16), the plate-like portion 134 can be elastically deformed toward the front side in the Y direction by the tool 80 (see arrow R150). For example, the operator can elastically deform the plate-like portion 134 toward the front side in the Y direction by further inserting the tip of the tool 80 inserted into the back side of the plate-like portion 134 in the Y direction upward.

[0054] When the plate-like portion 134 is elastically deformed toward the front side in the Y direction, accordingly, the engagement state between the first engaging portion 1341 and the first engaged portion 51 is released. Therefore, the operator can remove the device body 10 from the fitting 50 by moving the device body 10 upward with respect to the fitting 50 (that is, displacing it in the removal direction) while elastically deforming the plate-like portion 134 toward the front side in the Y direction.

[0055] In this way, according to this embodiment, the tool 80 is inserted through the opening 120 on the lower side of the apparatus main body 10 to easily release the engaged state between the first engaging portion 1341 and the first engaged portion 51. As a result, the apparatus main body 10 can be removed from the fitting 50. That is, according to this embodiment, the apparatus main body 10 can be removed from the fitting 50 with good workability while realizing a configuration that cannot be removed without using the tool 80. In other words, according to this embodiment, by ensuring the workability of removal by the tool 80, the first engaging portion 1341 that cannot easily release the engaged state between the fitting 50 and the apparatus main body 10 without the tool 80 can be realized.

[0056] Further, in this embodiment, as described above, since two first engaging portions 1341 are formed on one plate-like portion 134, the engaged states with the two first engaged portions 51 can be simultaneously released only by elastically deforming the one plate-like portion 134 toward the front side in the Y direction. Thereby, while realizing a highly reliable engaged state by the two first engaging portions 1341 in the attached state of the apparatus main body 10, the apparatus main body 10 can be removed from the fitting 50 with good workability.

[0057] Further, in this embodiment, as described above, since the lower end portion of the plate-like portion 134 has the inclined surface 1349 also between the two first engaging portions 1341 in the X direction, the tool 80 can be inserted between the two first engaging portions 1341 in the X direction to remove the apparatus main body 10 from the fitting 50. Thereby, the apparatus main body 10 can be removed from the fitting 50 without damaging the first engaging portion 1341 with the tool 80. Thereby, even after being removed a plurality of times, a highly reliable engaged state can be realized by the two first engaging portions 1341 in the attached state of the apparatus main body 10.

[0058] Also, in this embodiment, as described above, since the access recess 132 only communicates with the opening 120 and does not communicate with the inside of the apparatus main body 10, it is possible to prevent the inserted tool 80 from accidentally entering the inside of the apparatus main body 10. In other words, the access recess 132 has a bottom wall portion 1321 serving as the bottom and a side wall portion 1322 connected to the base portion 130, thereby protecting various electronic components inside the apparatus main body 10. Note that the side wall portion 1322 is formed on three sides (see FIG. 5) excluding the opening 120 side.

[0059] Also, in this embodiment, as described above, since the access recess 132 only opens downward through the opening 120, it is possible to effectively reduce the possibility that dust, foreign matter, etc. enter and accumulate in the access recess 132 through the opening 120. Further, since the opening 120 is provided only on the lower side surface portion 12, the opening 120 is hardly visible unless looked at from below, and an arrangement of the opening 120 that does not impair the design of the operating device 1 can be realized.

[0060] As described above, each embodiment has been described in detail, but the present invention is not limited to specific embodiments, and various modifications and changes are possible within the scope described in the claims. Also, it is possible to combine all or a plurality of the components of the foregoing embodiments.

[0061] For example, in the above-described embodiment, the first engaging portion 1341 is in the form of a claw having a locking portion on the upper side, but is not limited thereto.
