(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. 1 to 5 is provided in an air conditioner panel 400 of a vehicle shown in FIG. 7, for example. The air conditioner panel 400 is an operation panel that is provided in the center panel between the driver's seat and the passenger seat of the vehicle so as to face the rear of the vehicle and sets the control mode of the air conditioner mounted on the vehicle. Note that the vertical direction of the air conditioner panel 400 substantially matches the vertical direction of the vehicle, and the horizontal direction of the air conditioner panel 400 substantially matches the horizontal direction of the vehicle.

  The air conditioner panel 400 is provided with various switches such as a toggle switch 1 and a push switch 401 that are operated by a passenger. Specifically, three toggle switches 1 are provided at the center lower portion of the air conditioner panel 400 so as to be lined up on the left and right. On these toggle switches 1, a display panel 402 such as a liquid crystal display for displaying a control mode of the air conditioner is provided. In addition, push switches 401 that are pressed down are provided on the left and right sides of the air conditioner panel 400. The switches 1 and 401 are a switch for switching on and off the air conditioner, a switch for setting the temperature in the passenger compartment, a switch for setting the air volume, a switch for setting the mode, and the like.

  Hereinafter, the configuration of the toggle switch 1 will be described in detail with reference to FIGS. The toggle switch 1 includes a housing 2, a swing member 3, an intermediate member 4, a printed circuit board 5, and a pair of switches 6.

  The housing 2 has a housing space inside. In the accommodation space, each component constituting the toggle switch 1 is accommodated. The housing 2 is, for example, the housing of the air conditioner panel 400 of FIG. As shown in FIG. 1, an opening 21 a that conducts the inside and outside of the housing 2 is formed on the front surface 21 of the housing 2. The swing member 3 is provided in the opening 21a.

  The swing member 3 is provided integrally with the lever 32 formed in a shape extending in the front-rear direction with the direction perpendicular to the front surface 21 of the housing 2 as the front-rear direction and the front end of the lever 32 in the longitudinal direction. The operation knob 31 is provided. The lever 32 and the operation knob 31 may be integrated in any manner. For example, the lever 32 and the operation knob 31 may be integrated by injection molding, or a recess is provided in one of the lever 32 and the operation knob 31 and the other is fitted in the recess. A rounded convex portion may be provided and integrated by press-fitting these concave and convex portions.

  The operation knob 31 is formed in a shape protruding forward from the front end of the lever 32 and is provided so as to be exposed from the front surface 21 of the housing 2. The operation knob 31 is an operation unit that is operated by a vehicle occupant in a first direction P1 (see FIG. 3) that intersects the protruding direction or a second direction P2 (see FIG. 3) opposite thereto. Specifically, as shown in FIG. 3, the operation knob 31 has two surfaces 31a and 31b facing the operation directions P1 and P2. These surfaces 31a and 31b are portions that are gripped by the operator when the operation knob 31 is operated. In the following, the left-right direction on the paper surface in FIG. 1 is the left-right direction of the toggle switch 1, the up-down direction on the paper surface in FIG. 1 is the up-down direction of the toggle switch 1, and the left-right direction on the paper surface in FIG. Depth direction). A straight line extending in the protruding direction of the swing member 3 and passing through the center of the operation knob 31 in the left-right direction and the up-down direction is defined as a central axis L2 of the swing member 3 (see FIG. 3). In the example of FIG. 7, the up / down direction of the toggle switch 1 matches the up / down direction of the air conditioner panel 400, the left / right direction of the toggle switch 1 matches the left / right direction of the air conditioner panel 400, and the toggle switch 1 (operation knob 31). The protrusion direction (or depth direction) of the air conditioner coincides with the direction perpendicular to the air conditioner panel 400.

  The two grip surfaces 31a and 31b are formed obliquely with respect to the central axis L2 so as to gradually approach the central axis L2 as they approach the tip of the operation knob 31. In this way, the operation knob 31 has two sections as viewed from the cross section of FIG. 3 (cross section perpendicular to the rocking axis L1 of the rocking member 3 (see FIG. 2)) in order to be easily grasped by a finger. It is formed in a tapered shape that gradually decreases as the distance between the gripping surfaces 31a and 31b approaches the tip.

  The operation knob 31 is formed in a shape in which the width in the left-right direction is constant along the central axis L2 when viewed in the cross section of FIG. 2 (cross section parallel to the swing axis L1 and the central axis L2). The operation knob 31 corresponds to the operation unit of the present invention.

  The lever 32 is formed in a shape extending in the direction of the central axis L2. The lever 32 is provided inside the housing 2. That is, the lever 32 is provided invisible from the outside. Further, the lever 32 is in a neutral position in which the extending direction (in other words, the longitudinal direction of the lever 32) is not operated with respect to the operation knob 31 (in the example of FIG. 7). It is provided so as to be perpendicular to the front surface of the air conditioner panel 400. The lever 32 has two opposite directions P1 and P2 (see FIG. 2) about an axis L1 (see FIG. 2) extending in parallel with the front surface 21 of the housing 2 (the front surface of the air conditioner panel 400 in the example of FIG. 7). 3)). In the example of FIG. 2, the swing axis L <b> 1 is illustrated as extending in the left-right direction of the housing 2, but may be extended in a direction other than the left-right direction (for example, the vertical direction of the housing 2).

  Specifically, a support portion that supports the lever 32 is provided inside the housing 2 so as to allow the lever 32 to move around the axis L1 and restrict movement in other directions. As shown in FIG. 2, the support portion includes a pair of support surfaces 22 arranged so as to face each other with a space therebetween, and a pair of protrusion portions 23 protruding from each support surface 22 toward the other support surface 22. And have. In the example of FIG. 2, the pair of support surfaces 22 are provided so as to face the left-right direction of the housing 2. Each protrusion 23 is formed in a shape having a circular cross section when cut by a plane orthogonal to the axis L1.

  The lever 32 is provided between the pair of support surfaces 22. At this time, the lever 32 has a contact surface 32 a (see FIG. 2) that faces each support surface 22 and contacts each support surface 22. The contact surface 32 a is the left and right side surfaces of the lever 32. Moreover, the recessed part 32b (refer FIG. 2, FIG. 3) of the external shape similar to the protrusion part 23 is formed in the position which opposed the protrusion part 23 of each contact surface 32a. The protrusion 23 is fitted in the recess 32b in a state where the rotation around the axis L1 is allowed. Further, the diameters of the protrusion 23 and the recess 32b are set to be equal so that the movement of the protrusion 23 in the radial direction is restricted. In addition, the protrusion part may be formed in the lever 32 side, and the recessed part which the protrusion part fits in the housing | casing 2 side may be formed.

  Thus, the lever 32 is allowed to move around the axis L1 by fitting the protrusion 23 and the recess 32b, and is restricted from moving in the radial direction (the front-rear direction and the up-down direction of the toggle switch 1). Further, the movement of the lever 32 in the left-right direction is also restricted by the contact between the support surface 22 and the contact surface 32a.

  However, the lever 32 is not allowed to rotate around the axis L1 without limitation, and movement of a predetermined amount or more around the axis L1 is restricted. Specifically, as shown in FIG. 4, when the swing knob 31 is operated in any one of the upward and downward directions P <b> 1 and P <b> 2 inside the housing 2, the swing member 3 moves in the directions P <b> 1 and P <b> 2. A pair of restricting portions 25a, 25b for restricting the swinging of a predetermined amount or more is provided. One restricting portion 25a is a portion that is provided below the swinging member 3 and restricts swinging of a predetermined amount or more when the operation knob 31 is operated upward P1. The other restricting portion 25b is a portion that is provided above the swinging member 3 and restricts swinging of a predetermined amount or more when the operation knob 31 is operated downward P2.

  The swing member 3 is positioned at a distance from the restricting portions 25a and 25b when the operation knob 31 is not operated. When the operation knob 31 swings a predetermined amount, the swing member 3 hits the restricting portions 25a and 25b. A pair of regulated portions 35a and 35b are provided in which the swinging of the two is regulated. The restricted portions 35a and 35b are provided in the opposite portion 33 so as to face the first restricted portion 35a provided so as to face the first restricting portion 25a and the second restricting portion 25b. And a second regulated portion 35b provided in the first. When the operation knob 31 is operated upward P1, the swing of the swing member 3 by a predetermined amount or more is restricted by the contact between the first restricting portion 25a and the first restricted portion 35a. When the operation knob 31 is operated in the downward direction P2, the contact between the second restricting portion 25b and the second restricted portion 35b restricts the swing of the swing member 3 by a predetermined amount or more.

  When the operation knob 31 is not operated, the interval between the restricting portions 25a and 25b and the restricted portions 35a and 35b is set to a value corresponding to the amount of movement of the movable portion 62 until a switch 6 described later is turned on. ing. Therefore, the switch 6 is turned on when the swing member 3 swings the predetermined amount.

  Here, when a portion 33 (see FIGS. 2 and 3) on the opposite side of the operation knob 31 with the swing axis L <b> 1 sandwiched between the levers 32 is an opposite portion, the opposite portion 33 includes an intermediate member described later. 4 is formed (see FIGS. 2 and 3). Specifically, as shown in FIG. 2, the opposite portion 33 has a pair of wall portions 33a facing each other at an interval in the same direction as the direction in which the swing axis L1 extends, that is, the left-right direction. A space is formed between the pair of wall portions 33a. Each wall 33a is formed with a through-hole 33b as a connecting portion that penetrates in the normal direction of the wall 33a (the left-right direction of the toggle switch 1). When the position along the central axis L2 of the swing member 3 is the front-rear direction position, the through hole 33b formed in one wall portion 33a and the through hole 33b formed in the other wall portion 33a are the same. It is formed in the same shape in the front-rear direction position.

  As shown in FIG. 3, the through-hole 33 b is formed larger in diameter than the connecting portion 44 so that a gap 110 is formed between the through-hole 33 b and a connecting portion 44 of the intermediate member 4 described later. Specifically, the diameter of the through-hole 33b in the vertical direction of the toggle switch 1 (also the swinging direction of the swinging member 3) is set to be equal to the diameter of the connecting portion 44, while the center of the swinging member 3 is set. The diameter in the direction of the axis L <b> 2 (also the front-rear direction of the toggle switch 1) is formed in a long hole shape larger than the diameter of the connecting portion 44. The gap 110 is set to an amount corresponding to the difference between the movement trajectory of the through-hole 33 b when the operation knob 31 is operated and the movement trajectory of the connecting portion 44. The long diameter (the diameter in the direction of the central axis L2) of the through hole 33b is such that when the operation knob 31 is in the neutral position, the connecting portion 44 of the intermediate member 4 is the inner surface on the operation knob 31 side in the long diameter direction of the through hole 33b. When the operation knob 31 is operated to the limit position, the connecting portion 44 is determined so as to contact the inner surface of the through hole 33b on the switch 6 side in the major axis direction.

  Further, the distance d1 (see FIG. 3) between the tip of the operation knob 31 and the swing axis L1 and the distance d2 between the swing axis L1 and the through hole 33b are set to be equal. As shown in FIG. 4, the space member 34 (see FIG. 4) extends from the rear end to the front end in the extending direction (the direction of the central axis L <b> 2) inside the swing member 3 (the operation knob 31 and the lever 32). 1 and FIG. 2). For example, the space 34 is a portion for guiding the light of the light source mounted on the printed circuit board 5 to the tip of the operation knob 31. In this case, the space 34 has a light guide member such as acrylic. (Transparent resin) is arranged. Thereby, the tip of the operation knob 31 can be decorated with light.

  As shown in FIGS. 2 and 3, a printed circuit board 5 (hereinafter simply referred to as a substrate) is provided in the housing 2. The substrate 5 has one surface 51 of the substrate 5 facing in the direction of the oscillating member 3, that is, the front, and the other surface at the rear position (back side position) of the oscillating member 3 in the front-rear direction of the toggle switch 1. Arranged to face backwards. In other words, the substrate 5 is disposed substantially parallel to the front surface 21 of the housing 2. The substrate 5 is fixed to the housing 2 by screws 55 (see FIG. 2) or the like.

  A pair of switches 6 are mounted on the surface 51 of the substrate 5 facing the swing member 3. Each switch 6 is configured as a tact switch. That is, as shown in FIG. 3, the switch 6 includes a main body portion 61 and a movable portion 62 that is provided so as to protrude from the upper surface of the main body portion 61 and is supported by the main body portion 61 so as to be movable in the pressing direction. . Inside the main body 61, a member for applying a reaction force to hold the movable portion 62 at the upper limit position and a contact point are provided. When a pressing force larger than the reaction force is applied to the movable portion 62, the movable portion 62 moves in the pressing direction, whereby the contact is conducted, that is, the switch 6 is turned on. Thereafter, when the pressing force on the movable portion 62 is released, the movable portion 62 is automatically returned to the upper limit position by the reaction force applying member, whereby the contact is non-conductive, that is, the switch 6 is turned off. The reaction force of the switch 6 is set to a magnitude that automatically returns the operation knob 31 to the neutral position when the operation of the operation knob 31 is released.

  The pair of switches 6a and 6b are shown in FIG. 3 when the swinging member 3 is in a neutral position as viewed in a cross section when the toggle switch 1 is cut on a plane orthogonal to the swinging axis L1 of the swinging member 3. Are arranged at symmetrical positions with respect to the central axis L2. That is, one switch 6a is disposed above the central axis L2, and the other switch 6b is disposed below the central axis L2. The distance between one switch 6a and the central axis L2 is equal to the distance between the other switch 6b and the central axis L2. Further, the switches 6a and 6b are arranged at positions that are equidistant from a swing axis L3 of the intermediate member 4 described later.

  Further, the switches 6a and 6b have the same left-right direction as seen in a cross section when the toggle switch 1 is cut in a plane orthogonal to the front surface 21 of the housing 2 and parallel to the swing axis L1 shown in FIG. Placed in position. Further, the switches 6a and 6b are disposed at positions shifted in the left-right direction from the central axis L2 of the swing member 3 when viewed in the cross section of FIG. That is, the switches 6a and 6b are not arranged in the substrate 5 directly below the swinging member 3, and the space 34 formed inside the swinging member 3, for example, is directly below the swinging member 3 (see FIG. 4). An LED for supplying light is mounted.

  Note that components other than the toggle switch 1 may be mounted on the substrate 5. In this case, specifically, the tact switch of each push switch 401 of FIG. Moreover, the control part (not shown) of the display panel 402 or the air-conditioner panel 400 may be mounted on the substrate 5, for example.

  As shown in FIGS. 2 and 3, an intermediate member 4 is disposed between the swing member 3 and the switch 6 inside the housing 2. The intermediate member 4 is a member having a role of transmitting the operation of the operation knob 31 to the switch 6. The intermediate member 4 includes a main body portion 41 and a pair of shaft portions 42 that protrude in opposite directions with the main body portion 41 interposed therebetween and have the same axis L3. The pair of shaft portions 42 and the main body portion 41 are integrally formed. The shaft portion 42 is formed in a shape having a circular cross section when cut by a plane orthogonal to the axis L3.

  The intermediate member 4 is supported so as to swing about the axis L3 as the swinging member 3 swings. Specifically, as shown in FIG. 5, a support portion 24 that supports each shaft portion 42 so as to be rotatable in the direction of the axis L <b> 3 is provided inside the housing 2. The support portion 24 is composed of a pair of small piece portions 24 a and 24 b that face each other with an interval in the vertical direction of the toggle switch 1 (the swing direction of the swing member 3). The inner surfaces 24c of the small pieces 24a and 24b are formed in a shape that draws an arc having the same diameter as the shaft 42. The shaft portion 42 is supported so as to be rotatable around the axis L3 in a space surrounded by the inner surface 24c. At this time, as shown in FIG. 2, the direction of the axis L3 is parallel to the swing axis L1 of the swing member 3, and as shown in FIG. 3, the axis L3 and the swing axis L1 are the same up and down. The main body portion 41 and the shaft portion 42 are in the rear position with respect to the rear end of the swing member 3, and the shaft portion 42 (axis line L 3) is slightly in front of the movable portion 62 of the switch 6. Thus, the positions and orientations of the small pieces 24a and 24b are set. Further, the movement of the shaft portion 42 in the radial direction is restricted by the inner surface 24c. The axis L3 corresponds to the first axis of the present invention.

  Furthermore, the arcs 24c drawn by the small pieces 24a and 24b are notched so as to form an opening 24d toward the substrate 5. The shaft portion 42 can be inserted into the space surrounded by the arc 24c through the opening 24d. That is, by pushing the shaft portion 42 into the space surrounded by the arc 24c from the opening 24d, the small piece portions 24a and 24b are elastically deformed in a direction of widening the interval therebetween, and the shaft portion 42 is surrounded by the arc 24c. It can be assembled in the open space.

  Further, the intermediate member 4 has a connecting portion 43 that is provided so as to protrude forward from the main body portion 41, that is, toward the swinging member 3 side, and connects a connecting portion 44 and a main body portion 41 described later. The connection portion 43 protrudes from the vicinity of the center of the main body portion 41 in the vertical direction and is provided so as to be inserted into a space formed in the opposite portion 33 of the swing member 3. At this time, the outer surface of the connecting portion 43 is opposed to the inner surfaces of the left and right wall portions 33a of the opposite portion 33 via a minute gap (see FIG. 2). Thereby, the movement of the intermediate member 4 in the left-right direction is restricted.

  A connecting portion 44 that connects to the opposite portion 33 is provided at the front end of the connecting portion 43. The connecting portion 44 is configured as a pair of shaft portions that fit into the respective through holes 33 b formed in the opposite portion 33. One shaft portion 44 is provided so as to protrude rightward from the right side surface of the connection portion 43, and is inserted into the right through hole 33 b from the inner surface side of the right wall portion 33 a. The other shaft portion 44 is provided so as to protrude leftward from the left side surface of the connection portion 43 and is inserted into the left through hole 33b from the inner surface side of the left wall portion 33a.

  Each shaft portion 44 is formed in a shape having a circular cross section when cut by a plane orthogonal to the protruding direction. Further, the axis of one shaft portion 44 and the axis of the other shaft portion 44 are set to the same axis L4. The axis L4 is set in parallel with the swing axis L1 of the swing member 3. Further, the axis L4 is set to be orthogonal to the central axis L2 of the swing member 3.

  The shaft portion 44 is connected in a state where movement around the axis L4 is allowed in the through hole 33b. The shaft portion 44 has a diameter smaller than the long diameter (diameter in the direction of the central axis L2) of the through hole 33b formed in a long hole shape, and the short diameter (diameter in a direction perpendicular to the central axis L2) of the through hole 33b. ). Therefore, relative movement between the shaft portion 44 and the opposite portion 33 in the short diameter direction of the through hole 33 b, that is, the swinging direction of the opposite portion 33 (up and down direction of the toggle switch 1) is restricted. Further, the shaft portion 44 has a gap 110 (the gap 110 between the through hole 33b and the shaft portion 44 in the major axis direction of the through hole 33b, that is, the direction of the central axis L2 of the swing member 3 (the front-rear direction of the toggle switch 1). The relative movement between the opposite portion 33 is possible by the amount of the amount shown in FIG. 3, but the relative movement beyond the gap 110 is restricted.

  Eventually, the intermediate member 4 is connected to the swing member 3 by a link connection in which relative movement around the axis L4 is allowed, and relative movement is restricted except for movement for 110 minutes in the other directions. Yes. The connecting portion 44 corresponds to the contact portion of the present invention. The axis L4 corresponds to the second axis of the present invention.

  Further, when the line L5 (see FIG. 3) orthogonal to both the swing axis L3 of the intermediate member 4 and the axis L4 of the connecting portion 44 is the central axis of the intermediate member 4, the neutral position where the operation knob 31 is not operated. When in the position, the central axis L2 of the swing member 3 and the central axis L5 of the intermediate member 4 are in a parallel positional relationship.

  Further, as shown in FIG. 3, the intermediate member 4 includes a pair of arm portions 45 having one end connected to the main body portion 41 or the connection portion 43 and the other end extended to the position of the switch 6. The arm portion 45 extends in a direction substantially perpendicular to the central axis L5 of the intermediate member 4. Moreover, the arm part 45 is provided in the left-right direction position same as the installation position of the switch 6 in the left-right direction. That is, the arm portion 45 is disposed at a position shifted in the left-right direction from the central axis L <b> 2 of the swing member 3.

  The arm portion 45 is provided at a position slightly ahead of the movable portion 62 of the switch 6. The two arm portions 45a and 45b extend in directions opposite to each other. That is, one arm portion 45a extends in a direction (upward in the example of FIG. 3) where one switch 6a is located. The other arm 45b extends in the direction in which the other switch 6b is located (downward in the example of FIG. 3).

  A pressing portion 46 for pressing the movable portion 62 is provided on the surface of the tip of each arm portion 45a, 45b on the switch 6 side. The pressing portion 46 is formed so that the outer shape draws an arc when viewed in a cross section orthogonal to the swing axis L <b> 3 of the intermediate member 4. One pressing portion 46 is in contact with the front surface of the movable portion 62 of one switch 6a. The other pressing part 46 is in contact with the front surface of the movable part 62 of the other switch 6b.

  The arm portions 45a and 45b are formed in a symmetrical shape with respect to the swing axis L3 (see FIG. 2) of the intermediate member 4. Further, the pair of pressing portions 46 are disposed at symmetrical positions with respect to the swing axis L3. That is, the distance from the swing axis L3 to the one pressing portion 46 is equal to the distance from the swing axis L3 to the other pressing portion 46. Further, as shown in FIG. 3, the distance d3 between the axis L4 of the connecting portion 44 and the swing axis L3 and the distance d4 between the swing axis L3 and the pressing portion 46 are set to be equal.

  Next, the operation of the toggle switch 1 will be described. As shown in FIG. 6, when the operation knob 31 is operated upward P1, the opposite portion 33 swings in the opposite direction (that is, downward) to the operation direction P1. As the opposite portion 33 swings, the intermediate member 4 also swings downward. At this time, the intermediate member 4 is provided so as to be able to move relative to the swinging member 3 around the axis L4 parallel to the swinging axis L1. The angle formed by the central axis L2 of the moving member 3 and the central axis L5 of the intermediate member 4 changes. In other words, the angle formed between the intermediate member 4 and the swing member 3 changes as the swing member 3 swings.

  Further, the connecting portion 33b (through hole) of the opposite portion 33 moves along an arc locus centering on the swing axis L1 set in front of the connecting portion 33b, and thus swings while moving slightly forward. To do. On the other hand, the connecting portion 44 (shaft portion) of the intermediate member 4 moves along an arc locus centering on the swing axis L3 set rearward of the connecting portion 44, and thus swings while moving slightly rearward. To do. Here, since the gap 110 is provided between the through-hole 33b and the shaft portion 44, the difference between the forward movement amount of the through-hole 33b and the rearward movement amount of the shaft portion 44 at the time of swinging is determined as the gap 110. Can be absorbed.

  In other words, since the swing member 3 and the intermediate member 4 are link-coupled in a form having the gap 110, the intermediate member 4 can swing as the swing member 3 swings. As described above, when the operation knob 31 is operated in the direction P1, the swing member 3 swings in the clockwise direction as viewed in the cross section of FIG. 6, and the intermediate member 4 rotates counterclockwise along with the swing. Rocks in the direction of.

  Returning to the description of FIG. 6, when the intermediate member 4 swings downward, the lower arm portion 45 b moves backward, and conversely, the upper arm portion 45 a moves forward. Accordingly, the lower pressing portion 46 presses the lower switch 6b to turn on the switch 6b, while the upper pressing portion 46 is separated from the upper switch 6a, so that the switch 6a is kept off. The At this time, since the outer shape of the pressing portion 46 is circular, the lower pressing portion 46 changes the contact point with the pressing surface of the switch 6b, that is, slightly in the in-plane direction of the pressing surface. While sliding, the pressing surface is pressed. Thereby, it is possible to easily press the pressing surface.

  On the other hand, when the operation knob 31 is operated downward P2, the opposite portion 33 swings upward, and the intermediate member 4 swings upward along with the swing. In other words, when the operation knob 31 is operated in the direction P2, the swing member 3 swings in the counterclockwise direction as viewed in the cross section of FIG. 3, and the intermediate member 4 rotates clockwise in accordance with this swing. Swing in the direction. By the swinging of the intermediate member 4, the upper pressing portion 46 presses the upper switch 6a to turn it on.

  When the operation on the operation knob 31 is released, the intermediate member 4 and the swinging member 3 are automatically returned to the neutral position by the reaction force of the switch 6a, 6b that is pressed. The toggle switch 1 is used, for example, for temperature setting or air volume setting in vehicle interior air conditioning. In this case, when the operation knob 31 is operated upward P1, the set values such as the temperature and the air volume increase, and when the operation knob 31 is operated downward P2, the set values decrease.

  Hereinafter, the effect of this embodiment will be described. In the present embodiment, as shown in FIG. 3, the distance d1 between the tip of the operation knob 31 and the swing axis L1 of the swing member 3, the swing axis L1, and the connecting portions 33b and 44 (axis L4) Since the distance d2 is set to be equal, a force and a moving amount equivalent to the operating force and operating amount of the operating knob 31 can be generated in the connecting portions 33b and 44. Further, since the distance d3 between the connecting portion 44 and the swing axis L3 of the intermediate member 4 and the distance d4 between the swing axis L3 and the pressing portion 46 are set to be equal, the force generated in the connecting portion 44 In addition, the switch 6 can be pressed with a force and a moving amount equivalent to the moving amount. Thereby, the operation force and the operation amount of the operation knob 31 can be set to values equivalent to the movement amount and the reaction force of the movable portion 62 when the movable portion 62 of the switch 6 is directly operated.

  Further, the intermediate member 4 linked to the swing member 3 is interposed between the swing member 3 and the switch 6 so that the toggle switch 1 intersects the protruding direction of the operation knob 31, in other words, the operation. It is possible to suppress an increase in size in a direction (vertical direction in the present embodiment) parallel to the swing directions P1 and P2 of the knob 31. That is, unlike the toggle switch 300 of the comparative example shown in FIG. 15, in the configuration in which the switch 302 is pressed directly by the swing member 301 without interposing an intermediate member, the moving amount and reaction force of the movable part of the switch 302 are reduced. In order to make use of this, it is necessary to set the ratio of the distance d10 between the tip of the operating knob of the swinging member 301 and the swing axis to the distance d11 between the swing axis and the pressing portion to 1: 1. As a result, the swinging member 301 becomes longer in the vertical direction. As in the present embodiment, by interposing the intermediate member 4 and reducing the size in the direction parallel to the swing direction, another component (example in FIG. 7) is located at a position adjacent to the swing direction of the toggle switch 1. Then, the display panel 402) can be easily arranged.

  Further, as shown in FIG. 15, in the configuration in which no intermediate member is interposed, in order to make use of the movement amount and reaction force of the movable part of the switch 302 while suppressing the size in the vertical direction, the switch 302 and the board on which the switch 302 is mounted. It is necessary to arrange 303 at a position closer to the front surface of the housing than the substrate 5 of the present embodiment, or to arrange the substrate above the swing member as in Patent Document 1. When other parts such as the push switch 401, the display panel 402, and the LED are arranged around the toggle switch 1 as in the air conditioner panel 400 of FIG. 7, the board for the other parts is the front of the housing. It may not be possible to place in the vicinity. For example, in the example of FIG. 7, in order to secure the operation amount in the pressing direction of the push switch 401, the board on which the toggle switch of the push switch 401 is mounted has a certain distance in the depth direction from the front surface of the housing. There is a need. In this case, if the toggle switch 300 of FIG. 15 or the toggle switch of Patent Document 1 is adopted instead of the toggle switch 1, a substrate for the toggle switch and a substrate for other components are separately provided. It is necessary to provide wiring for connecting a plurality of substrates. In this case, the operation panel including the toggle switch is increased in size or the number of parts is increased.

  On the other hand, in the toggle switch 1 of the present embodiment, what is the distances d1 to d4 as long as the ratio of the distances d1 and d2 is 1: 1 and the ratio of the distances d3 and d4 is 1: 1. Even if it is a value, the reaction force of the switch 6 can be utilized. That is, by interposing the intermediate member 4, the degree of freedom of the arrangement position of the switch 6 and the substrate 5 on which the switch 6 is mounted can be increased. In other words, the switch 5 and the intermediate member 4 are configured so that the ratio of the distances d1 to d4 is 1: 1 regardless of the distance of the substrate 5 from the front surface of the housing 2. The reaction force of 6 can be utilized. As a result, the board 5 of the switch 6 can be easily made common with the boards for other components. By making the substrate 5 and the substrate for other components common, it is possible to suppress an increase in the size of the operation panel including the toggle switch 1 and to suppress the number of components.

In this manner, the protruding portion 98 is formed in a tapered shape in which the width between the first and second outer peripheral surfaces 98a and 98b is gradually reduced toward the tip in the protruding direction. These outer peripheral surfaces 98a and 98b correspond to the first and second outlines of the present invention.

  As shown in FIG. 10, a substrate 5 and a pair of switches 6 mounted on the substrate 5 are provided inside the housing 8. The substrate 5 and the switch 6 are accommodated in an inner casing 11 described later. As in the first embodiment, the substrate 5 is disposed substantially parallel to the front surface of the housing 8 at a position behind the swing member 9. The substrate 5 is fixed to the housing 8 together with the inner housing 11 by screws 55.

  The switch 6 is mounted on the surface of the substrate 5 on the swing member 9 side. As shown in FIG. 10, the two switches 6a and 6b are disposed at positions that are symmetrical in the vertical direction about the central axis L6 of the swing member 9 when the swing member 9 is in the neutral position. Further, as shown in FIG. 9, the switch 6 is disposed at the center position in the left-right direction where the central axis L6 of the swing member 9 is located when the swing member 9 is in the neutral position.

The protruding portion 112 is provided to protrude toward the protruding portion 98 at a position facing the protruding portion 98 of the swing member 9. In addition, the protrusion part 112 is provided in two places at intervals in the left-right direction corresponding to the number (two pieces) of the protrusion part 98 (refer FIG. 9).

  The protruding portion 112 is located on the movement locus of the first outer peripheral surface 98a of the protruding portion 98 when the oscillating member 9 oscillates with the first fulcrum portion 96a as a fulcrum, and has a shape along the movement locus. The first outer peripheral surface 112a is formed. The first outer peripheral surface 112a is formed in a shape that draws an arc centered on the axis L7 of the first fulcrum portion 96a when the swinging member 9 is in the neutral position, as seen in the cross section of FIG. The first outer peripheral surface 112a functions as a guide portion that guides the swinging member 9 so as to swing about the first fulcrum portion 96a.

  The protrusion 112 is positioned on the swing locus when the swing member 9 swings with the second fulcrum portion 96b as a fulcrum, and is formed in a shape along the swing locus. It has a surface 112b. The second outer peripheral surface 112b is formed in a shape that draws an arc centered on the axis L8 of the second fulcrum portion 96b when the swinging member 9 is in the neutral position as seen in the cross section of FIG. The second outer peripheral surface 112b functions as a guide portion that guides the swinging member 9 so as to swing about the second fulcrum portion 96b.

  And the protrusion part 112 is formed in the taper shape from which the width | variety between these outer peripheral surfaces 112a and 112b becomes small gradually as it goes to the front-end | tip of the protrusion direction. The first outer peripheral surface 112 a and the second outer peripheral surface 112 b are connected to each other at the tip of the protruding portion 112.

  Further, the tip of the protrusion 112 is provided at a position facing the tip of the protrusion 98 when the swing member 9 is in the neutral position. At this time, the tip of the protrusion 112 and the tip of the protrusion 98 may be in contact with each other, or may have a minute gap that does not turn on the switch 6. In addition, the protrusion part 112 is equivalent to the guide part of this invention. The first outer peripheral surface 112a and the second outer peripheral surface 112b correspond to the first guide portion and the second guide portion of the present invention.

  As shown in FIG. 10, a pair of pin members 10 as intermediate members are provided between the swing member 9 and the switch 6. The pin member 10 is formed in a linearly extending shape, that is, a rod shape. The pin member 10 is inserted into the guide hole 111. The guide hole 111 allows movement in the axial direction and restricts movement in the radial direction. One end 101 in the axial direction of one pin member 10a is in contact with one pressing portion 97a, and the other end 102 is in contact with the front surface of one switch 6a. One end 101 in the axial direction of the other pin member 10b is in contact with the other pressing portion 97b, and the other end 102 is in contact with the front surface of the other switch 6b. The front end 101 of the pin member 10 corresponds to the contact portion of the present invention. The pin member 10 corresponds to a linear moving member.

  In addition, the pin member 10 is formed such that a part 103 (hereinafter referred to as a head portion) from the end portion 101 in contact with the swing member 9 is provided outside the guide hole 111 and has a larger diameter than the guide hole 111. Has been. Furthermore, when the swinging member 9 is in the neutral position, the head 103 is disposed at a distance closer to the swinging member than the opening of the guide hole 111. That is, a portion other than the head portion 103 of the pin member 10 is exposed between the head portion 103 and the opening of the guide hole 111. The exposure amount of the pin member 10 is set to a value corresponding to the movable amount of the switch 6.

  Next, the operation of the toggle switch 7 will be described. As shown in FIG. 13, when the operation knob 91 is operated in the downward direction P2, a force acts in the direction in which the support surface 83 is pressed on the first fulcrum portion 96a located on the opposite side to the operation direction P2. On the other hand, a force acts on the second fulcrum part 96b located on the same side as the operation direction P2 in the direction of the switch 6 where the support surface 83 is not provided. As a result, the second fulcrum part 96b falls off the support surface 83, and the swing member 9 has the first fulcrum part 96a as a fulcrum, in other words, around the axis L7 of the first fulcrum part 96a. It swings in the operation direction P2 side (counterclockwise as viewed in FIG. 13). At this time, since the outer peripheral surface 961 (see FIG. 11) at the end 960 of the first fulcrum portion 96a is formed in an arc shape, the outer peripheral surface 961 slides on the support surface 83 in a direction along the arc. .

  Further, the first outer peripheral surface 98 a of the protruding portion 98 of the swing member 9 is guided along the first outer peripheral surface 112 a of the protruding portion 112 of the inner housing 11. Thereby, the swinging of the swinging member 9 with the first fulcrum part 96a as a fulcrum is ensured. That is, the swinging member 9 is prevented from wobbling in directions other than the swinging direction when the swinging member 9 is swinging about the first fulcrum portion 96a.

  As the swing member 9 swings in the operation direction P2 side, the pressing portion 97b on the operation direction P2 side presses the pin member 10b on the operation direction P2 side. At this time, since the outer shape of the pressing portion 97b is formed in a circular arc shape, the front end 101 is pressed while slightly sliding in the in-plane direction of the front end 101 of the pin member 10b. Thereby, the pin member 10b moves linearly to the switch 6b side, and as a result, the switch 6b is turned on. Further, the pressing portion 97a opposite to the operation direction P2 is separated from the pin member 10a. As a result, the switch 6a on the opposite side is kept off.

  Thereafter, when the operation of the operation knob 91 is released, the pin member 10b moves linearly in the direction of the swing member 9 by the reaction force of the switch 6b. By the movement of the pin member 10b, the swing member 9 swings in the clockwise direction, that is, upward in FIG. 13 with the first fulcrum portion 96a as a fulcrum, and the second fulcrum portion 96b is surrounded by the support surface 83. Fits in. As described above, when the operation on the operation knob 91 is released, the swing member 9 automatically returns to the neutral position.

  On the other hand, when the operation knob 91 is operated upward P1, a force acts in the direction in which the support surface 83 is pressed on the second fulcrum portion 96b located on the opposite side to the operation direction P1. A force acts on the first fulcrum portion 96a located on the same side as the direction P1 in the direction of the switch 6 where the support surface 83 is not provided. As a result, the first fulcrum part 96a falls off the support surface 83, and the swing member 9 has the second fulcrum part 96b as a fulcrum, in other words, about the axis L8 of the second fulcrum part 96b. Swings to the operation direction P1 side.

  Further, the second outer peripheral surface 98 b of the protruding portion 98 of the swing member 9 is guided along the second outer peripheral surface 112 b of the protruding portion 112 of the inner housing 11. Thereby, the rocking | fluctuation member 9 is reliably rock | fluctuated about the 2nd fulcrum part 96b as a fulcrum. That is, when the swing member 9 is swinging about the second fulcrum portion 96b, the swing member 9 is prevented from wobbling in directions other than the swing direction.

  When the swing member 9 swings in the operation direction P1 side, the pressing portion 97a on the operation direction P1 side presses the pin member 10a on the operation direction P1 side. Thereby, the pin member 10a moves linearly to the switch 6a side, and as a result, the switch 6a is turned on. Further, the pressing portion 97b on the side opposite to the operation direction P1 is separated from the pin member 10b. As a result, the switch 6b on the opposite side is kept off.

  Thereafter, when the operation on the operation knob 91 is released, the pin member 10a linearly moves in the direction of the swing member 9 by the reaction force of the switch 6a. By this movement of the pin member 10 a, the swing member 9 swings downward, and the first fulcrum portion 96 a falls within the region surrounded by the support surface 83. In this way, the swing member 9 automatically returns to the neutral position.

  Hereinafter, the effect of this embodiment will be described. When the operation knob 91 is operated downward P2, the ratio between the distance between the tip of the operation knob 91 and the first fulcrum part 96a and the distance between the first fulcrum part 96a and the second pressing part 97b. Accordingly, the second pressing portion 97b can generate a force and an amount of movement corresponding to the above. When the operation knob 91 is operated upward P1, the distance between the tip of the operation knob 91 and the second fulcrum part 96b, and the distance between the second fulcrum part 96b and the first pressing part 97a A force and a movement amount corresponding to the ratio can be generated in the first pressing portion 97a. At this time, since the ratio of the distances is set to 1: 1, a force and a movement amount equivalent to the operation force and the operation amount of the operation knob 91 are applied to the second pressing portion 97b or the first pressing portion 97a. Can be generated. Since the pin member 10 that moves linearly is provided between the swing member 9 and the switch 6, the force and movement amount substantially the same as the force and movement amount generated in the pressing portions 97 a and 97 b by the pin member 10. The amount of movement can be transmitted to the switch 6.

  Thereby, the operation force and operation amount of the operation knob 91 can be set to the same value as the movement amount and reaction force of the switch 6 when the switch 6 is directly operated.

  The swing member 9 includes two fulcrum portions 96a and 96b (swing axis L7 and L8). When the swing member 9 swings in one direction P1, the fulcrum portion 96b opposite to the direction P1 swings. When it becomes a moving fulcrum and swings in the other direction P2, the fulcrum part 96a opposite to the direction P2 becomes a swing fulcrum, and therefore a direction parallel to the swing directions P1 and P2 (in the vertical direction in this embodiment). The distance between the operation knob 91 and the tip and the swinging fulcrum and the distance between the swinging fulcrum and the pressing portion 97 can be increased while suppressing the increase in size. Since the size in the vertical direction can be reduced, other components (the display panel 402 in the example of FIG. 7) can be easily arranged at positions adjacent to the swing direction of the toggle switch 7.

  On the other hand, as shown in FIG. 15, when there is one swing fulcrum and the swing fulcrum is provided on the central axis of the swing member 301, the tip of the operation knob and the swing fulcrum Distance d10 and the lever ratio, which is the ratio of the distance d11 between the swing fulcrum and the pressing portion, to be 1: 1, the distance d11 increases, and as a result, in a direction parallel to the swing direction. It will increase in size.

  In the comparative example of FIG. 15, as described in the first embodiment, the substrate 303 of the switch 302 is attached to the front surface of the housing in order to reduce the vertical size and to set the lever ratio to 1: 1. The board 303 and the board for parts other than the toggle switch 7 may be separated from each other.

  On the other hand, in the present embodiment, the pin member 10 is provided between the swing member 9 and the switch 6 so that the force and the moving amount from the swing member 9 can be transmitted to the switch 6 almost as they are. By changing the length of the member 10, the switch 6 and the substrate 5 can be arranged at desired positions in the front-rear direction. As a result, the board 5 and the board for other components can be easily made common, an increase in the size of the operation panel including the toggle switch 7 can be suppressed, and the number of parts can be reduced.

  Further, the swinging member 9 is provided with a tapered projecting portion 98 projecting to the opposite side in the projecting direction of the operation knob 91 and projecting toward the projecting portion 98 so as to face the projecting portion 98 on the housing side. A tapered protrusion 112 is provided. Therefore, even if a force is applied to the operation knob 91 in the pressing direction, the tips of the projecting portions 98 and 112 come into contact with each other, and the projecting portion 98 is forcibly connected to any outer peripheral surface of the projecting portion 112. By moving along the lines 112a and 112b, it is possible to suppress the operation knob 91 from moving in the pressing direction. As a result, it is possible to suppress the two switches 6a and 6b from being pressed simultaneously.
