Abstract

PROBLEM TO BE SOLVED: To provide a switching device capable of avoiding giving the sense of discomfort at slide operation even when warpage occurs in a housing.SOLUTION: In an LED lamp, a plurality of V-notches 46a capable of giving click feeling are formed in the direction in which a flat plate 46 of an operation knob 43 expands. Therefore, even when a frame 20 is warped to the slide direction of the operation knob 43 and a space Sp between the flat plate 46 of the operation knob 43 and an inner wall of the frame 20 becomes narrow, the narrowed space Sp does not affect a concavo-convex part which gives clicking feeling and is formed in the direction in which the flat plate 46 expands, not in the direction of the thickness of the flat plate 46. Thus, even when the frame 20 is warped, no sense of discomfort occurs in slide operation by having a clicking mechanism structured with the plurality of V-notches 46a formed in the direction to which the flat plate 46 expands and a triangle projection 26, to be engaged with the plurality of V-notches 46a, of the frame 20.

Description

  The present invention relates to a switch device capable of switching a circuit connection state of a circuit board accommodated in a flat casing and an illumination device using the switch device.

  As a switch device and a lighting device relating to the present invention, for example, there is one disclosed in FIG. 2 of Patent Document 1 below (in the [Background Art] column, the numbers in parentheses are the codes described in Patent Document 1). Corresponding to).

  The switch device of the illumination device disclosed in Patent Document 1 switches the flat discharge tube (13) constituting the illumination device (11) to a lighting / extinguishing control that accompanies opening / closing of a door, or manually turns it on / off. The slide switch (43) mounted on the circuit board (40) in the case (12), and the operation for engaging the slide switch (43) with the movable part (43b) that constitutes the main body part (43a).

  However, while miniaturization of slide switches (switch bodies) has progressed along with recent reductions in size and size of electronic components, the knobs that are operated from the outside are large enough to be operated with fingers from the viewpoint of operability. It is necessary to maintain it. For this reason, it is difficult to generate a click feeling that can give a sufficient feel to the operator only by a click mechanism provided in the switch body due to an unbalance between the sizes of the operation knob and the switch body. That is, since the switch body is very small and the click feeling caused thereby is not so great, the click feeling of the switch body is hardly transmitted to the operator through a very large operation knob.

  Therefore, as shown in FIG. 13A, in the switch device 110 including the switch body 111 mounted on the circuit board 103 and the operation knob 113 that can be engaged with the switch knob 111a of the switch body 111, The knob 113 includes a flange-like plate-like portion 113a accommodated in the housing 100, a knob portion 113b surrounded by the plate-like portion 113a, and a thickness direction about the center of the plate-like portion 113a in the sliding direction. And a projecting portion 113c protruding toward the surface.

  Accordingly, as shown in FIG. 13B, when the operator slides the operation knob 113 (in the arrow direction shown in FIG. 13B), the unevenness formed on the inner wall surface 101a of the lid 101 of the housing 100 Since the protrusion 113c gets over the portion (not shown), it is possible to give a sufficient click feeling to the operator by the vibration accompanying this. In FIGS. 13A and 13B, the symbol R indicates a flat surface (flat surface) having no curvature.

  However, when the flat casing 100 (the lid 101 and the main body 102) in which the switch main body 111 and the circuit board 103 are accommodated is made of synthetic resin such as ABS, the lid 101 and the main body 102 are provided. Is often configured to be engageable by engaging claws or the like that fit together. Therefore, when a strong external force is applied to the housing 100, the housing itself may be warped. For example, as shown in FIG. 13C, when the casing is screwed and fixed to the ceiling RR of the vehicle interior that is curved, warping along the curved surface of the ceiling RR is caused on the casing 100 ′ itself. It can occur in the direction of sliding operation (sliding direction).

  Since the operation knob 113 is for sliding the switch knob 111 a of the switch body 111 mounted on the circuit board 103, the operation knob 113 is generally configured to maintain a positional relationship parallel to the circuit board 103. Therefore, when the casing 100 ′ is warped in the sliding direction in this way, the plate-like portion 113a of the operation knob 113, the inner wall surface 101a of the lid portion 101, and the gap S ′ are as shown in FIG. It becomes narrower than the gap S that should be maintained. In particular, since the gap S ′ becomes narrower as it approaches the end of the plate-like portion 113a, the end may come into contact with the inner wall surface 101a of the housing 100 during the sliding operation.

  For example, as shown in FIG. 13C, when the gap S ′ between the plate-like portion 113a of the operation knob 113 and the inner wall surface 101a of the lid 101 is extremely narrow, the projection 113c of the operation knob 113 is The casing 100 remains pressed against the inner wall surface 101 a of the lid 101. Therefore, the protrusion 113c becomes an obstacle to the slide movement of the operation knob 113, and there is a problem that the operator may feel that the slide operation becomes very heavy or feel uncomfortable.

  Further, as shown in FIG. 13D, even if the operation knob 113 can be slid, the plate shape of the operation knob 113 at a position Q before the position P that should originally be reached (see FIG. 13B). When the end of the portion 113a contacts the inner wall surface 101a of the lid portion 101, the movement of the operation knob 113 is blocked by the inner wall surface 101a. Therefore, in such a case, there is a problem that the operator can feel a feeling and discomfort that the slide operation suddenly becomes heavy from the middle of the slide operation.

The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a switch device that can make it difficult to give an uncomfortable feeling to the slide operation even when the casing is warped.

The operation portion has a flat plate portion that extends in the flat direction of the housing and does not contact the inner wall of the housing, and a side edge portion extending in the sliding direction of the flat plate portion is formed in the housing. A technical feature is that a plurality of concave and convex portions that can cause a click feeling at each switching position corresponding to the connection state of the circuit are formed by engaging with the convex portions. .

  According to this, the switch operation portion has a flat plate portion that extends in the flat direction of the housing and does not contact the inner wall of the housing, and the side edge portion extending in the sliding direction of the flat plate portion includes A plurality of concavo-convex portions that can cause a click feeling at each switching position corresponding to the connection state of the circuit are formed by engaging with the convex portions formed on the slab. That is, the plurality of concavo-convex portions that can cause a click feeling are formed in the direction in which the flat plate portion of the switch operation portion expands. As a result, even if the housing is warped in the sliding direction of the switch operation portion and the gap between the flat plate portion of the switch operation portion and the inner wall of the case is narrowed, the uneven portion capable of generating a click feeling is the thickness of the flat plate portion. Since it is not formed in the vertical direction, it is difficult to be affected by the narrowing of the gap interval, and it is difficult to extend in the direction in which the flat plate portion expands (this effect tends to extend in the thickness direction of the flat plate portion).

  Further, in the invention of the switch device, the plurality of concave and convex portions are formed with three or more concave portions, and the inclination angle of the groove wall forming the outermost concave portion located on the outermost side among these concave portions is the maximum. You may comprise so that it may be set smaller than the inclination-angle of the groove wall which forms the inner side recessed part located inside an outer recessed part.

  Furthermore, in the invention of the switch device, at least one of the outermost concave portion and / or the inner concave portion and the convex portion is initially set against the counterpart side to be engaged when the engagement state is released. A first groove wall that abuts and a second groove wall that abuts after the first groove wall are formed, and the inclination angle of the second groove wall is larger than the inclination angle of the first groove wall. You may comprise so that one may be set small.

  In the invention of the switch device, a gap is formed between the end portion of the flat plate portion and the inner wall of the housing within a range of the maximum allowable deformation amount when the housing is bent in the sliding direction. You may comprise as follows.

  Furthermore, in the invention of the switch device, the switch operating portion is formed with a gap portion extending in the sliding direction along the side edge portion inside the side edge portion where the plurality of uneven portions are formed. You may comprise as follows.

  Furthermore, in the invention of the switch device, the switch operation portion has the side edge portions on which the plurality of uneven portions are formed on both sides in the slide direction, and the casing includes the switch operation portion. You may comprise so that the said convex part which can be engaged with the several uneven | corrugated | grooved part formed in a both-sides edge part is formed corresponding to each uneven | corrugated part of the said both-sides edge part.

  In order to achieve the above object, in the invention of a lighting device, the lighting device includes the switch device, and the switch body portion is turned on by turning on the light source connected to the circuit board by the sliding operation of the switch operation portion. It is a technical feature to control light extinction or light emission mode. According to this, the switch body controls the lighting, extinction, or light emission mode of the light source connected to the circuit board by the sliding operation of the switch operating unit. Thereby, when the said illuminating device is assembled | attached to the curved curved surface like the ceiling of a vehicle interior, even if a curvature | warp arises in a housing | casing, it can be made hard to give an uncomfortable feeling to slide operation.

  According to the switch device of the present invention, even if the casing is warped in the sliding direction of the switch operating section and the gap interval between the flat plate section of the switch operating section and the inner wall of the casing is narrowed, the effect of this is It is difficult to extend in the thickness direction and in the direction in which the flat plate portion expands. Therefore, by forming a click mechanism with a plurality of concave and convex portions formed in the direction in which the flat plate portion expands and the convex portions in the housing that engage with each other, even if the housing warps, the slide operation becomes uncomfortable. Can be difficult.

  As shown in FIGS. 5 and 6, the operation knob 43 is a resin molded member made of synthetic resin such as ABS, and the knob part 45, the flat plate part 46, the engaging part 47 and the support leg 48 are integrally formed. Has been. The operation knob 43 is configured such that the engagement portion 47 engages with the switch knob 41 a of the switch body 41 mounted on the control board 15 and the knob portion 45 is exposed from the switch opening 22 of the frame 20. The switching mechanism 41b can be operated from the outside by the slide operation.

  As described with reference to FIG. 1 (A), the knob 45 is exposed to the outside through the switch opening 22 to enable the slide operation of the slide switch 40. That is, the LED lamp 10 is operated by the operator with a finger, and a plurality of non-slip grooves 45a formed substantially perpendicular to the sliding direction are provided on the surface (FIG. 4A, FIG. 5 (A), (B), (C)).

  The flat plate portion 46 is a flat plate member having a rectangular shape extending in the flat direction of the LED lamp 10, that is, the longitudinal direction L and the width direction W of the frame 20, and in the case of this embodiment, side edge portions 46L and 46L extending in the slide direction. 'Is set to be longer than both end portions 46W in the sliding direction (FIGS. 5B and 5F). The length of the flat plate portion 46 is the minimum value at which the switch opening portion 22 can be closed by the flat plate portion 46 depending on the opening width in the longitudinal direction of the switch opening portion 22 formed in the frame 20 and the sliding movement amount of the knob portion 45. Is set to

  Further, in the end portion 46W of the flat plate portion 46, chamfering may be performed on the corner portion (inside the broken line β shown in FIG. 6A) on the side where the knob portion 45 is formed. As a result, the distance between the end 46 </ b> W of the flat plate portion 46 and the inner wall surface of the frame 20 can be increased.

  Further, one side edge 46L of the flat plate portion 46 is set so as to expand in the width direction as compared with the other side edge 46L '(FIGS. 5D and 5E), and the wide side A plurality of (three in the present embodiment) V notches 46a (V-shaped grooves) are formed in the center in the longitudinal direction of the edge portion 46L, and a gap portion 46b is formed between the tab portion 45L and the knob portion 45. Is formed (FIGS. 5B and 5F).

  The plurality of V notches 46a are formed along the side edge 46L in accordance with the switching position of the circuit connection by the switch body 41 mounted on the control board 15, and between the three triangular valleys, It is configured so that two peaks are formed (FIGS. 5B, 5C, and 5F). In addition, the valley shape by this V notch 46a is comprised so that it may substantially correspond to the triangular mountain shape of the triangular convex part 26 formed in the convex part formation wall 25 mentioned above, and the click mechanism which can produce a click feeling is produced. It is composed.

  Further, the V notch forming portion 46d in which such a plurality of V notches 46a are formed is set to be thicker than the support portions 46c located on both sides thereof, and is supported by these support portions 46c. As a result, the V notch forming portion 46d can be bent to the inside where the gap portion 46b is formed. Therefore, as described later, the triangular convex portion 26 formed on the convex forming wall 25 is Even when the plurality of V-notches 46a are engaged, the triangular convex portion 26 can get over the mountain caused by the plurality of V-notches 46a relatively easily. Moreover, since it becomes possible to bend in this way, even if the height of the mountain formed by the plurality of V notches 46a is increased or the depth of the valley is increased, the mountain can be overcome, and the amount of vibration can be reduced. A click mechanism that causes a large click feeling can be configured.

  The plurality of V-notches 46a can correspond to the “plurality of concave and convex portions” recited in the claims, and the triangular convex portion 26 formed on the convex portion forming wall 25 is claimed. This can correspond to the “convex portion” described in the range.

  The engaging portion 47 has a rectangular parallelepiped shape extending in the sliding direction of the operation knob 43, and is formed on the back side where the knob portion 45 of the flat plate portion 46 is formed (FIGS. 5A, 5C, 5C). (F)). The engaging portion 47 includes a knob receiving hole 47a formed in a direction substantially perpendicular to the flat plate portion 46, and hollow portions 47b formed on both sides of the knob receiving hole 47a. The size and depth of the hole are set so as to be engageable with the switch knob 41a of the switch body 41 mounted on the control board 15. The length of the engaging portion 47 in the sliding direction is set to be larger than the length of the switch body 41 in the sliding direction.

  The support legs 48 are support members that support the operation knob 43 on the control board 15 on which the switch body 41 is mounted. The support legs 48 are in contact with the surface of the control board 15 on which the switch body 41 is mounted substantially perpendicularly. It is formed in the shape of a plate. That is, it is formed on the back side of the flat plate portion 46 so as to face the both sides of the engaging portion 47 so as to sandwich the engaging portion 47 along the side edge portion 46L of the operation knob 43, and is in contact with the control board 15. At the tip, protruding contact portions 48a are formed at portions located at both ends in the sliding direction (FIGS. 5A, 5C, and 5F). Thereby, since the contact part with respect to the control board 15 is kept to the minimum, the frictional resistance with respect to the surface of the control board 15 is suppressed, and the slide of the operation knob 43 is made smooth. The length from the back surface of the flat plate portion 46 to the contact portion 48a, that is, the height of the support leg 48, is a value that can sufficiently engage the switch knob 41a of the switch body 41 with the knob receiving hole 47a of the engaging portion 47. Is set.

  When the knob 45 of the operation knob 43 configured as described above is passed through the switch opening 22 of the frame 20 and is exposed so as to be exposed to the front side (outside) of the frame 20, the inside of the frame 20 is shown in FIG. It looks as shown in 4 (C). In FIG. 4C, the triangular convex portion 26 is engaged with the V notch 46a located in the middle of the three. As a result, when the operation knob 43 is slid in either direction, the triangular convex portion 26 of the frame 20 gets over the mountain between the V notches 46a formed in the flat plate portion 46. Is given to the operator of the operation knob 43.

  Further, as shown in FIGS. 4A and 4B, an annular convex portion 20b protruding inside the frame 20 is formed around the switch opening 22, and the flat portion 20c is the switch opening 22. Therefore, when the operation knob 43 is assembled to the switch opening 22, a gap Sp is formed between the inner wall surface of the frame 20 and the flat plate portion 46 (FIG. 4A). ), (C)). That is, the flat plate portion 46 of the operation knob 43 can be assembled to the frame 20 so as to be lifted from the inner wall surface of the frame 20 by the amount of inward projection by the annular convex portion 20b.

  Further, the presence of such a flat portion 20c around the switch opening 22 stabilizes the sliding movement of the operation knob 43 assembled to the frame 20, and the flat portion 20c is not the entire circumference of the switch opening 22. Since the frictional resistance is reduced by providing a part, smooth sliding is possible in the sliding operation.

  Therefore, for example, even when a strong external force is applied to the housing (lens 11, frame 20 and housing 30) of the LED lamp 10 and the LED lamp 10 itself is warped, the warp is within the range of the gap Sp. The end portion 46 </ b> W of the flat plate portion 46 does not contact the inner wall surface of the frame 20. For this reason, since the inner wall of the frame 20 does not cause an obstacle or blockage to the sliding movement of the operation knob 43, even if the casing (the lens 11, the frame 20 and the housing 30) is warped, the sliding operation is uncomfortable. It can be difficult to give.

  Further, when chamfering is performed on a corner portion (inside the broken line β shown in FIG. 6A) of the end portion 46W of the flat plate portion 46 where the knob portion 45 is formed, the flat plate portion 46 is provided. Since it is possible to further increase the distance between the end 46W of the frame and the inner wall surface of the frame 20, even if the casing (the lens 11, the frame 20 and the housing 30) is warped, it is difficult to give a sense of incongruity to the slide operation. be able to.

  The gap Sp formed between the inner wall surface of the frame 20 and the flat plate portion 46 is the maximum allowable deformation when the housing (the lens 11, the frame 20, and the housing 30) of the LED lamp 10 is bent in the sliding direction. It is set based on the amount (maximum warpage, maximum deflection, etc.).

  By configuring the triangular convex portion 26 and the operation knob 43 of the frame 20 in this way, for example, as shown in FIG. 7A, when the operation knob 43-1 is slid to one end side, the flat plate portion 46 is formed. Since the triangular convex portion 26 of the frame 20 is engaged with the V notch 46a-1 on the right side of the figure in the V notch 46a, a click feeling is caused at the same time, and at the same time, the switch knob 41a of the switch body 41 The circuit connection is switched, for example, the LED unit 50 shifts to “always on”.

  Further, as shown in FIG. 7B, when the operation knob 43-2 is slid to the middle position, the frame is placed in the middle V notch 46a-2 in the figure out of the V notches 46a of the flat plate portion 46. Since the triangular projection 26 of the 20 engages, a click feeling also occurs at the same time, and at the same time, the circuit connection is switched by the switch knob 41a of the switch body 41, for example, the LED unit 50 shifts to “always off”. To do.

  Further, as shown in FIG. 7C, when the operation knob 43-3 is slid to the other end side, the frame is placed on the V notch 46a-3 on the left side of the V notch 46a of the flat plate portion 46. At this time, a click feeling is generated at the same time, and at the same time, the circuit connection is switched by the switch knob 41a of the switch body 41. Move to “On / off control”.

  As described above, in the LED lamp 10 according to the present embodiment, the operation knob 43 extends in the flat direction of the casing (the lens 11, the frame 20, and the housing 30) of the LED lamp 10, and the end 46 </ b> W contacts the inner wall of the frame 20. Each of the side edge portions 46L extending in the sliding direction of the flat plate portion 46 has a flat plate portion 46 that does not have any contact with the triangular convex portion 26 formed on the frame 20 and corresponds to the connection state of the circuit. A plurality of V notches 46a capable of generating a click feeling at the switching position are formed. That is, the plurality of V notches 46 a capable of generating a click feeling are formed in a direction in which the flat plate portion 46 of the operation knob 43 expands.

  As a result, even if the housing (lens 11, frame 20 and housing 30) is warped in the sliding direction of the operation knob 43 and the gap Sp between the flat plate portion 46 of the operation knob 43 and the inner wall of the frame 20 is reduced. Since the uneven portion capable of generating the click feeling is not formed in the thickness direction of the flat plate portion 46, it is difficult to be affected by the narrowing of the interval Sp, and the flat plate portion 46 is difficult to extend (this is not possible). The influence is likely to reach the thickness direction of the flat plate portion 46). Accordingly, a plurality of V notches 46a formed in the direction in which the flat plate portion 46 expands and the triangular convex portion 26 of the frame 20 with which these engage with each other constitute a click mechanism, whereby the housing (the lens 11, the frame 20 and the housing). Even if warpage occurs in 30), it is possible to make it difficult to give an uncomfortable feeling to the slide operation.

  Further, in the LED lamp 10 according to the present embodiment, the maximum allowable deformation amount (the maximum warpage amount, the maximum deflection amount, etc.) when the casing (the lens 11, the frame 20, and the housing 30) is bent in the sliding direction of the slide switch 40. ), A gap Sp is formed between the end 46W of the flat plate portion 46 and the inner wall surface of the frame 20. Thus, within the range of the maximum allowable deformation amount, the end 46W of the flat plate portion 46 does not contact the inner wall surface of the frame 20, so even if a strong external force is applied to the housing and the housing itself is warped, the frame The inner wall surface 20 does not cause any obstacle or blockage to the sliding movement of the operation knob 43. Therefore, even if the casing is warped, it is possible to make it difficult to give a strange feeling to the slide operation.

  Furthermore, in the LED lamp 10 according to the present embodiment, the operation knob 43 has a gap 46b extending in the sliding direction along the side edge 46L on the inner side of the side edge 46L where the plurality of V notches 46a are formed. Is formed. As a result, the side edge portion 46L where the plurality of V notches 46a are formed can be bent toward the inside of the side edge portion 46L, so that the height of the mountain forming the V notch 46a can be increased. The depth of the valley can be increased. For this reason, when engaging with the convex part 26 formed on the convex part forming part 25 of the frame 20, the click notch 46 a has a large peak or valley, and a click mechanism that can cause a click feeling with a large vibration amount is configured. can do. Therefore, a clear click feeling can be given to the operator.

  Next, a modified example of the operation knob constituting the slide switch 40 will be described with reference to FIGS. FIG. 8 shows the external appearance of the modified example of the operation knob as seen from six sides (plane, front, bottom, left side, right side, back), and FIG. The external appearance seen from six sides (plane, front, bottom, left side, right side, back) of the modified example is shown.

  In the operation knob 43 described with reference to FIG. 5, the V notch 46a and the gap 46b formed in the flat plate portion 46 are formed only on one side edge 46L. For example, the operation knob 43 ′ shown in FIG. As described above, the V notches 46a and 46a ′ and the gaps 46b and 46b ′ may be formed on both side edge portions 46L and 46L ′, respectively. Correspondingly, the frame 20 is formed with two convex forming walls 25 facing the triangular convex portions 26 so as to sandwich the switch opening 22 (not shown).

  That is, the flat plate portion 46 'may be configured symmetrically in the width direction 46W. As a result, V notches 46a and 46a ′, gap portions 46b and 46b ′, support portions 46c and 46c ′, and V notch forming portions 46d and 46d ′ are formed on both side edge portions 46L and 46L ′, respectively. Compared with the operation knob 43 shown in FIG. 4, the click mechanism for generating a click feeling can be configured in two places, so that even if there is a problem with the click mechanism on one side, the click feeling can be generated with the remaining click mechanisms. it can. In addition, since a click feeling is generated at two locations, a click feeling with a large amount of vibration can be obtained. Therefore, it is possible to give a reliable and clear click feeling to the operator.

  Further, like the operation knob 43 ″ shown in FIG. 9, V notches 46a, 46a ″ and gaps 46b, 46b ″ are formed in both side edge portions 46L, 46L ′, respectively, but the operation knob 43 shown in FIG. Rather than constructing the flat plate portion 46 'symmetrically in the width direction 46W as in the case of', the V-notch 46a is formed such that the side edge portion 46L and the side edge portion 46L "are staggered except for the middle V-notch. , 46a "may be formed in two places. That is, V notches 46a are formed in two places on one side edge 46L of the flat plate part 46", and the other side edge 46L "is made rotationally symmetrical. The V notches 46a ″ may be formed at two locations.

  As a result, V notches 46a and 46a "are formed on both sides of the side edge portions 46L and 46L" in the middle, while V notches 46a are formed only on one end side of the side edge portion 46L or the side edge portion 46L "at both ends. (Or V notch 46a ″) is not formed. For this reason, when the operation knob 43 is slid in the middle, compared with the case where the slid operation is performed toward either side, a strong click feeling can be generated. It is possible to inform sensuously that the user has operated to the position by the intensity of the click feeling.

  As described above, according to the operation knob 43 ′ shown in FIG. 8 and the operation knob 43 ″ shown in FIG. 9, the side edges 46L, 46L ′ (46L) on which the plurality of V notches 46a, 46a ′ (46a ″) are formed. ") On both sides of the slide switch 40 in the sliding direction, and a plurality of V notches formed on both side edges 46L and 46L '(46L") of the operation knob 43' (43 ") on the inner side of the frame 20 Convex portions engageable with 46a, 46a ′ (46a ″) are formed corresponding to the V notch forming portions 46d, 46d ′ (46a ″) of the side edge portions 46L, 46L ′ (46L ″). . Thereby, compared with the case where the plurality of V-notch forming portions 46d and 46d ′ (46a ″) are formed only on one end side of the side edge portion 46L (the operation knob 43 shown in FIG. 5), a click feeling is generated. The click mechanism (a plurality of V notch forming portions 46d, 46d ′ (46a ″) and a convex forming wall 25 positioned so as to sandwich the switch opening 22 is formed so that the triangular convex portion 26 faces each other). Since it can be configured at a location, even if there is a problem with the click mechanism on one side, the click feeling can be generated with the remaining click mechanisms. In addition, since a click feeling is generated at two locations, a click feeling with a large amount of vibration can be obtained. Therefore, it is possible to give a reliable and clear click feeling to the operator.

  Subsequently, a further modification of the operation knob will be described with reference to FIGS. FIG. 10 shows an external view of a modified example of the operation knob (operation knob 143) viewed from six sides (plane, front, bottom, left side, right side, back), and FIG. A perspective view of the operation knob 143 is shown. FIG. 12 is an explanatory diagram illustrating a configuration example of a V notch and a corner notch (a plurality of uneven portions) of the operation knob 143.

  In the operation knob 43 described so far with reference to each drawing, the V-notches 46a, 46a ′, 46a ″ having the same shape are used as the flat plate portions 46, 46 as the concave portions of the plurality of concave and convex portions that can cause a click feeling. In the modified example described here, the shape of these recesses is different. For example, when three or more concave portions of the plurality of concave and convex portions are formed, among these concave portions, the shape of the outermost concave portion positioned on the outermost side and the inner concave portion positioned on the inner side of the outermost concave portion The configuration is different from the shape.

  Further, in the operation knob 43 described so far, when the opening width of the switch opening 22 for exposing the operation knob 43 from the frame 20 is set to be relatively wide, if the operation knob 43 is only in the sliding direction. Since it can also move in the width direction perpendicular to it, it may cause backlash of the operation knob 43 during the slide operation.

  For this reason, in the modified example described here, as shown in FIGS. 10 and 11, the operation knob 143 has a rib 145 b having a semi-conical truncated cone shape that is set to a height that is approximately half the height of the knob portion 145. The structure is provided near the four corners. Thereby, the clearance gap between the switch opening part 22 and the knob part 145 of the flame | frame 20 can be made small, and even if there exists such a clearance gap, the part which contacts the switch opening part 22 can be limited to the rib 145b. Therefore, generation of unnecessary frictional force can be suppressed by minimizing the contact portion of the switch opening 22 with the peripheral edge of the opening. Therefore, the operability of the operation knob 143 can be further improved.

  Further, in the operation knob 43 described so far, the depth of the anti-skid groove 45a formed in the knob part 45 is not set so deep. Therefore, in the modified example described here, the anti-skid groove 145a of the knob part 145 is set. Is formed to a depth of about twice the depth of the non-slip groove 45a of the operation knob 43. This makes it easier for the operator's finger to be hooked, so that the operability can be further improved.

  Specifically, with respect to an example in which the shapes of the outermost concave portion and the inner concave portion are different, specifically, concave portions (a plurality of concave and convex portions formed on the side edge portion 46L of the flat plate portion 46, such as the operation knob 143, are formed. Of the groove wall forming the V notch 146a1 (outermost recess) located at both ends is smaller than the inclination angle of the groove wall forming the corner notch 146a2 (inner recess) located in the middle. Set.

  Thereby, for example, when the triangular convex portion 26 of the frame 20 is engaged with the middle corner notch 146a2, the operation required when the operation knob 143 is slid in either end direction. When the triangular protrusion 26 of the frame 20 and the V-notch 146a1 are engaged with each other, the operation knob 143 is slid in the middle position with respect to the load (the operation load necessary for releasing the engagement). It becomes possible to make larger than the operation load at the time.

  That is, the triangular notch 146a2 that engages with the V-notch 146a1 at both ends and the triangular notch 146a2 that is engaged with the middle corner notch 146a2 overcomes the engagement with the triangular notch 146a2, and the corner notch 146a2 has a groove wall rather than the V notch 146a1. Since the inclination angle is set so as to increase, the magnitude relationship of the operation load required for the slide operation is angular notch 146a2> V notch 146a1. For this reason, it is possible to give a feeling of operation heavier to the operator than the slide operation from the center toward the end than the slide operation from the end toward the center.

  In the operation knob 43 described above, since the V-shaped notch 46a having the same shape is formed in the flat plate portion 46, the operation knob 43 is slid with substantially the same operation load at both ends and in the middle position. It is possible. For this reason, although there is a feature that it is easy to perform a slide operation regardless of the position of the operation knob 43, as shown in FIG. 7, for example, the operator pushes the operation knob 43 from one end side (FIG. 7A) in the middle ( When switching to FIG. 7 (B)), there may be an “overrun” in which the operation knob 43 is slid to the other end side (FIG. 7 (C)) that is not planned.

  On the other hand, in the operation knob 143 according to the modified example, the V notch 146a1 and the corner notch 146a2 are configured so that the magnitude relationship of the operation load required for the slide operation is such that the angle notch 146a2> V notch 146a1. Depending on the setting of the operation load, such “overrun” can be suppressed. Similarly, when the operation knob 143 is switched from the other end side (FIG. 7 (C)) to the middle (FIG. 7 (B)), the operation knob 143 exceeds the position of the middle (FIG. 7 (B)). Sliding to the side (FIG. 7A) can also be suppressed.

  As an example of setting the operation load, for example, the operation load of the corner notch 146a2 is set to be approximately 1.5 to 2 times the operation load of the V notch 146a1. That is, when an operation load of approximately 1.5 to 2 times the operation load directed from the end to the middle is applied, the operation knob 143 located at the center can slide toward the end so that the V notch can slide. The groove wall angle of 146a1 and the corner notch 146a2 is set.

  More specifically, for example, as shown in FIG. That is, the inclination angles θ11, θ12 (= θ11) of the groove walls a11, a12 constituting the V notch 146a1 are set to 45 degrees with respect to the end face (reference plane in the sliding direction) of the side edge 46L (V-shaped The opening θa is 90 degrees), and the inclination angles θ21 and θ22 of the groove walls a21 and a22 constituting the angle notch 146a2 are set to 80 degrees with respect to the same end surface. The depth of the V notch 146a1 is set to Dp1 from the end face of the side edge 46L, and the depth of the bottom face a23 of the corner notch 146a2 set substantially parallel to the end face is set to Dp2 (> Dp1). ing.

  Further, in this modified example, for the V notch 146a1, among the groove walls constituting the V shape, the groove wall close to the corner notch 146a2 is formed in a two-stage configuration including the groove wall a12 and the groove wall a13. A groove wall a13 having an inclination angle θ13 smaller than the inclination angle θ12 is provided in the middle of the groove wall a12 forming the inclination angle θ12 and connected to the end surface of the side edge 46L. That is, in the groove wall of the V-notch 146a1 toward the corner notch 146a2, when the triangular convex part of the mating partner is released from the engaged state, the triangular wall part a12 (first groove) with which the triangular convex part first comes into contact. Wall) and a groove wall a13 (second groove wall) that comes into contact with the groove wall a12 are formed, and the inclination angle θ13 of the groove wall a13 is set smaller than the inclination angle θ12 of the groove wall a12.

  Further, in this modified example, as shown in FIG. 12 (B), the triangular convex portion 126 formed on the convex portion forming wall 125 symmetrically with respect to the one-dot chain line is not formed in a simple triangular shape but on the frame 20. Standing walls b11 and b14 that rise from the convex forming wall 125 to a height Ha closer to 90 degrees (for example, substantially perpendicular) than the inclination angles θ21 and θ22 of the groove wall of the angular notch 146a2 with respect to the wall surface of the convex forming wall 125. And mountain walls b12 and b13 which are inclined at an inclination angle θb with respect to the vertical of the wall surface and the height from the convex forming wall 125 to the triangular top is set to Hb. The inclination angle θb ′ is set smaller than the inclination angles θ11 and θ12 of the groove walls a11 and a12 of the V notch 146a1, and the triangular apex θb (= 2θb ′) is the V-shaped opening. It is set smaller than θa. The height Hb of the triangular convex portion 126 is set slightly lower than the depth Dp1 of the V notch 146a1.

  Accordingly, as shown in FIG. 12C, when the triangular convex portion 126 and the V notch 146a1 are engaged with each other and the triangular convex portion 126 moves in the direction of the angular notch 146a2 by the slide operation of the operation knob 143. In the range of Dp1 ′ which is shallower than the depth Dp1 of the V notch 146a1, the triangular convex portion 126 forms the support portion 46c while the mountain wall b12 is in sliding contact with the groove wall a12 of the V notch 146a1. It bends away from the wall 125 (downward in the figure).

  Then, when the triangular convex portion 126 further moves in the direction of the corner notch 146a2 and moves out of the range of the depth Dp1 ′, next, as shown in FIG. Since the support portion 46c is bent by the remaining depth (Dp1-Dp1 ′) so as to be pressed against the groove wall a13 of the notch 146a1, when the V-notch 146a1 is overcome, as shown in FIG. The triangular protrusion 126 and the corner notch 146a2 are engaged to cause a click feeling.

  Note that the operation load required in the state of FIG. 12D is smaller than the operation load in the range of the depth Dp1 ′ (FIG. 12C). For this reason, the operation load Pi required for the triangular convex portion 126 to disengage from the V notch 146a1 is the direction in which the support portion 46c is separated from the convex forming wall 125 by the depth Dp1 ′ of the V notch 146a1 (same as above). It is set by the sum of the load in the sliding direction required to bend (downward in the figure) and the load in the sliding direction of the switch knob 41a required to switch the switching mechanism 41b of the switch body 41. In this case, the standing walls b11 and b14 of the triangular convex portion 126 do not contact the groove walls a11, a12 and a13 of the V notch 146a1.

  Further, as shown in FIG. 12E, in the state where the triangular convex portion 126 and the corner notch 146a2 are engaged, the triangular convex portion 126 is moved in the direction of the opposite V notch 146a1 by the sliding operation of the operation knob 143. When moved, the standing wall b11 of the triangular convex portion 126 slides on the groove wall a21 of the corner notch 146a2 to bend the support portion 46c away from the convex forming wall 125 (downward in the figure). That is, when engaged with the corner notch 146a2, first, the groove wall a21 and the standing wall b11 of the corner notch 146a2 are in sliding contact with each other in the range of the height Ha of the standing wall b11 of the triangular convex portion 126. Note that the groove width of the corner notch 146a2 is set wider than the width of the triangular protrusion 126 in the sliding direction because the error in the mounting position of the switch body 41 mounted on the control board 15 and the switching mechanism 41b. This is to absorb an error of the slide position due to.

  Further, when the triangular convex portion 126 further moves in the direction of the opposite V notch 146a1, the sliding contact between the groove wall a21 of the angular notch 146a2 and the standing wall b11 of the triangular convex portion 126 is finished, and then FIG. F), the peak wall b12 of the triangular convex portion 126 is a groove of the angular notch 146a2 in the remaining height (Hb-Ha) from the convex forming wall 125 to the triangular top. It press-contacts to the corner | angular part of wall a21 and the side edge part 46L. As a result, the support portion 46c is further bent, and then over the corner notch 146a2 and is engaged with the V notch 146a1 to generate a click feeling.

  The operating load required in the state of FIG. 12F is smaller than the operating load in the range of the height Ha of the standing wall b11 of the triangular convex portion 126 (FIG. 12E). Therefore, the operation load Po required for the triangular convex portion 126 to disengage from the angular notch 146a2 is such that the support portion 46c is separated from the convex forming wall 125 by the height Ha of the standing wall b11 of the triangular convex portion 126. It is set by the sum of the load in the sliding direction required to bend in the direction (downward in the figure) and the load in the sliding direction of the switch knob 41a required to switch the switching mechanism 41b of the switch body 41. In this case, the mountain walls b12 and b13 of the triangular protrusion 126 do not contact the groove walls a21, a22 and a23 of the corner notch 146a2.

  In the example described with reference to FIGS. 12C to 12F, the case where the triangular convex portion 126 moves from the right side to the left side in FIG. The case where the triangular convex portion 126 moves to the right side can be similarly described. In this case, it should be noted that the mountain walls b11 and b12 of the triangular convex portion 126 are replaced with the mountain walls b14 and b13, and the groove wall a21 of the corner notch 146a2 is replaced with the groove wall a22.

  As described above, in the modified example described with reference to FIGS. 10 to 12, the mountain walls b12 and b13 of the triangular convex portion 126 that engages with the V notch 146a1 (outermost concave portion) when the engagement state is released. On the other hand, a groove wall a12 (first groove wall) that contacts first and a groove wall a13 (second groove wall) that contacts after the groove wall a12 are formed, and the inclination angle θ12 of the groove wall a12 is larger than the inclination angle θ12. The inclination angle θ13 of the groove wall a13 is set smaller. Further, the standing walls b11, b14 (firstly abutting against the groove walls a21, a22 of the corner notches 146a2 (inner convex portions) that are engaged with the triangular convex portion 126 (convex portion) when the engagement state is released. 1st groove wall) and mountain walls b12, b13 (second groove wall) that come into contact with the standing walls b11, b14 are formed, and the angle of inclination of the standing walls b11, b14 is approximately 90 degrees (for example, substantially vertical). The inclination angle θb ′ of the walls b12 and b13 is set smaller.

  As a result, the first and second abuts each other with a severe inclination, and then a gentle inclination, so that the operation load required when the operation knob 143 is slid is mainly set to the inclination angle with which the first abutment is made. It can be changed arbitrarily. In addition, by making the inclination of the abutting later gentle, it is possible to solve the problem that the operation load becomes excessively large and the slide operation becomes difficult.

  In the modification described with reference to FIGS. 10 to 12, the groove walls and the like having different inclination angles are configured in two stages. By setting the angle (including the stage), it becomes possible to set a delicate operation feeling during the slide operation, such as setting the operation load more finely or changing it almost continuously.

  Further, in the modified example described with reference to FIGS. 10 to 12, the two-stage angle setting is applied to the V-notch 146 a 1 (outermost recess), but the two-stage angle setting is applied to the corner notch 146 a 2 (inner recess). The above angle setting may be performed, or two or more angle settings may be performed on both the V notch 146a1 (outermost recess) and the corner notch 146a2 (inner recess). Furthermore, in the modified example, the two-step angle setting is applied to both the V notch 146a1 (outermost concave portion) and the triangular convex portion 126 (convex portion). Setting may be applied.

  In the embodiment described above, the triangular convex portions 26 and 126 are formed on the convex portion forming walls 25 and 125 of the frame 20, and a plurality of V notches 46a are formed on the side edge portion 46L of the flat plate portion 46 of the operation knobs 43 and 143. , 146a1, etc., conversely, a plurality of V-notches are formed on the convex-forming walls 25, 125 of the frame 20, and one is provided on the side edge 46L of the flat plate portion 46 of the operation knobs 43, 143. You may comprise so that a triangular convex part may be formed. Thereby, the effect | action and effect similar to what was mentioned above can be acquired.

  In the above-described embodiment, each member is integrally formed with the operation knobs 43 and 143 using one type of synthetic resin material such as ABS. For example, a V notch in which a plurality of V notches 46a, 146a1, etc. are formed. The formation part 46d and the support part 46c may be formed using other synthetic resins, and the same actions and effects as described above can be obtained also by this.

  Furthermore, in the embodiment described above, the gap 46b is formed in the flat plate portion 46 of the operation knobs 43 and 143. However, for example, a range in which a plurality of V notches 46a are formed without forming such a gap 46b. May be formed using a resin that is relatively softer than other portions, for example, a rubber-based resin material. Thereby, since it is not necessary to form the gap part 46b, damage due to the formation of the gap part 46b can be suppressed.

  Furthermore, in the above-described embodiment, the lens 11 is provided only on the frame 20 and is configured to be a “single-sided emission type” that emits illumination light to the frame 20 side, but the housing 30 also corresponds to the lens 11. A lens may be provided so as to be a “double-sided light emission type” that emits illumination light also to the housing 30 side.

  In this case, the reflecting plate 13 is replaced with the reflecting plate 13 without providing the reflecting plate 13 in the light emitting space surrounded by the partition 35, and the housing 30 is mounted like the lens opening 21 of the frame 20. Also, a lens opening is provided, and the lens opening is covered with a lens corresponding to the lens 11. Thereby, since illumination light is emitted not only from one surface of the LED lamp but also from the other surface, for example, an LED lamp that can simultaneously illuminate both sides partitioned by the partition wall by attaching the partition wall to the partition wall.
