However, in the conventional turn signal switch, the interlocking member formed with the movable contact is configured to slide (slide) in the same direction as the operation knob (slide knob) slides. There was a problem like this.
Since the turn signal switch is usually one of a plurality of switches formed on a case (handle switch case) fixed in the vicinity of the grip grip of the handlebar, the operation range of the operation knob (the slide knob slides). The dynamic operation range) cannot be set too large. On the other hand, since the interlocking member that interlocks with the operation knob is formed with a movable contact that can be in contact with or separated from the fixed contact, it is possible to reliably perform electrical conduction and interruption of the conduction by the fixed contact and the movable contact. Needs to move the interlocking member relatively large.

  However, the conventional turn signal switch is configured so that the interlocking member slides (slides) in the same direction in accordance with the sliding operation of the slide knob. Since it is limited within the operation range, a very large operation cannot be performed, and it may be difficult to reliably perform contact or separation between the fixed contact and the movable contact.

  The present invention has been made in view of such circumstances. The movable contact of the interlocking member can be operated relatively large according to the sliding operation of the operation knob, and the movable contact can be brought into contact with or separated from the fixed contact. An object of the present invention is to provide a turn signal switch that can be surely performed.

An operation knob that can be pushed in from the door, and an interlocking member that forms a movable contact that can be brought into contact with or separated from the fixed contact fixed to the case side in conjunction with the sliding operation and the pushing operation of the operation knob. The movable contact and the fixed contact come into contact with each other by sliding operation of the operation knob to blink a desired side blinker disposed on the vehicle, and the movable contact is operated by pushing the operation knob. In the turn signal switch in which the flashing of the blinker can be canceled by separating the fixed contact from the fixed contact, the interlocking member includes a sliding operation and a pushing operation of the operation knob. Is conjunction with swingable around a predetermined swing axis, and, the operation knob, the slide knob slidably operated in the left and right are normally biased to a neutral position, it is formed in the slide knob The push button is configured with a push button that can be pushed, and the push button has an operation side inclined surface that can be opposed to an operated side inclined surface formed on the interlocking member by a sliding operation of the slide knob, The movable contact may be separated from the fixed contact by interlocking the interlocking member by a cam action by the operation-side inclined surface and the operated-side inclined surface during a pushing operation .

According to a second aspect of the invention, the turn signal switch according to claim 1, wherein the push button together with the shaft member, which are protruded to be inserted into the interlocking member, the operating-side inclined surface on the shaft member It is formed.

According to a third aspect of the present invention, in the turn signal switch according to the first or second aspect, the operation-side inclined surface and the operated-side inclined surface are formed in a curved shape following the swinging locus of the interlocking member. It is characterized by comprising.

According to a fourth aspect of the present invention, in the turn signal switch according to any one of the first to third aspects, the fixed contact of the movable contact is determined based on a dimension between the operation knob and the swing shaft of the interlocking member. The dimension between the contact portion and the swing shaft of the interlocking member is set to be larger.

According to a fifth aspect of the present invention, in the turn signal switch according to any one of the first to fourth aspects, the interlocking member is formed on the interlocking member, and the swinging state of the interlocking member by the sliding operation of the operation knob is maintained. In addition, the present invention is characterized in that a moderation providing means for providing moderation at the time of the left and right sliding operation of the operation knob is provided.

  According to the first aspect of the present invention, since the interlocking member can swing around the predetermined swinging shaft in conjunction with the sliding operation and pushing operation of the operation knob, the interlocking member can respond to the sliding operation of the operation knob. Thus, the movable contact of the interlocking member can be operated relatively large, and the movable contact can be reliably brought into contact with or separated from the fixed contact.

Further , the push button has an operation-side inclined surface that can be opposed to the operated-side inclined surface formed on the interlocking member by the sliding operation of the slide knob, and the operation-side inclined surface and the operated-side inclined surface at the time of pushing operation Since the movable contact can be separated from the fixed contact by interlocking the interlocking member by the cam action, the blinker blink can be canceled with a relatively simple configuration.

According to the invention of claim 2 , the push button is formed by protruding the shaft member inserted through the interlocking member, and the operation member inclined surface is formed on the shaft member. The interlocking member can be swung reliably and smoothly during the push-button pressing operation while allowing the interlocking member to swing.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 1, the turn signal switch according to the present embodiment is formed in a handle switch case 1 (case) fixed in the vicinity of a grip grip G of a handle bar H provided in a two-wheeled vehicle (vehicle). When the operation knob 2 (slide knob 2a) is slid in the left-right direction in the drawing, the movable contact and the fixed contact come into contact with each other to turn the turn signal (turn signal) on the desired side (either left or right). The flasher is blinked, and the movable contact and the fixed contact are separated by the pushing operation of the operation knob 2 (push button 2b), so that blinking of the blinker can be canceled.

  More specifically, as shown in FIGS. 1 to 10, the turn signal switch includes a handle switch case 1 (case), a slide knob 2 a and a push button 2 b constituting the operation knob 2, and a movable contact 7. The interlocking member 5 and the terminal plate 6 on which the fixed contact 8 is formed are mainly configured. As described above, the handle switch case 1 can be fixed in the vicinity of the grip G of the handle bar H of the two-wheeled vehicle (vehicle). In addition to the turn signal switch according to the present invention, the headlight of the two-wheeled vehicle is lowered. A plurality of switches capable of operating electrical components mounted on the two-wheeled vehicle, such as a dimmer switch knob 3 for switching to irradiation or front irradiation or a horn switch knob 4 for sounding a horn, are provided. In the figure, symbol n indicates a screw for fixing the terminal plate 6 to the handle switch case 1, and the screw n is in a screw hole of a boss 1a (see FIG. 8) formed in the handle switch case 1. It can be inserted.

  The operation knob 2 (slide knob 2a, push button 2b) is formed so as to protrude from the handle switch case 1, and can be slid rightward and leftward from the neutral position, and can be pushed in from the neutral position. is there. In the present embodiment, the operation knob is composed of a slide knob 2a that is always urged to a neutral position and can be slid left and right, and a push button 2b that is formed on the slide knob 2a and can be pushed. Yes. In addition, it may have a single operation knob that can be slid right and left from the neutral position and that can be pushed from the neutral position.

  As shown in FIGS. 4 to 6, the slide knob 2a is slidably assembled with the handle switch case 1 in a straight line in the left-right direction, and is always urged to the neutral position by the coil spring S1. It consists of a part formed in a chevron with a protruding part. A through hole 2ab is formed at the center of the slide knob 2a, and the push button 2b is fitted into the through hole 2ab and assembled.

  The push button 2b is assembled so that it can be pushed into the handle switch case 1 (slide knob 2a), and is urged by the coil spring S2 so as to always protrude, and is composed of a substantially cylindrical part. Thus, when the slide knob 2a is slid to the left and right, the push button 2b follows, and when the push button 2b is pressed, the push button 2b can be pushed against the urging force of the coil spring S2. .

  In the push button 2b according to the present embodiment, a shaft member 11 inserted through the interlocking member 5 is formed to protrude. The shaft member 11 is composed of a rod-shaped member, and has a male screw formed on the base end 11b side. The push button is engaged by screwing the male screw with a female screw formed on the push button 2b. It is integrated with 2b, and its tip part 11a has a smaller diameter than the substrate 11b. Reference numeral 9 in the figure denotes a spacer attached to the shaft member 11.

  In addition, an operation-side inclined surface 12 that can be opposed to an operated-side inclined surface 5g (described in detail later) formed on the interlocking member 5 is formed at a predetermined position of the shaft member 11. The operation-side inclined surface 12 is formed of a pair of left and right integrally formed at a predetermined position of the shaft member 11. Thus, when the sliding operation on the slide knob 2a is performed, the shaft member 11 moves in the left-right direction together with the push button 2b. When the pushing operation of the push button 2b is performed, the pushing direction (of the shaft member 11) (Longitudinal direction).

  The interlocking member 5 contacts or separates from the fixed contact 8 fixed to the handle switch case 1 side (specifically, the terminal plate 6) in conjunction with the sliding operation of the slide knob 2a and the pressing operation of the push button 2b. The movable contact 7 to be obtained is formed, a recess 5a through which the shaft member 11 can be inserted, a through hole 5b through which the tip end portion 11a of the shaft member 11 can pass, and a groove 5c into which the movable contact 7 can be fitted, It is mainly composed of an insertion hole 5d through which the swing shaft L can be inserted, a projection 5e, and an arm 5f. In the figure, symbol S3 indicates a coil spring for constantly urging the movable contact 7 toward the fixed contact 8 side.

  The concave portion 5a has a shape that is greatly opened toward the operation knob 2. When the slide knob 2a is slid in either the left or right direction, a part 2aa (see FIG. 7) of the slide knob 2a is opened to the concave portion 5a. The interlocking member 5 can be interlocked by pressing the wall portion. In addition, an operation-side inclined surface 5g is integrally formed at a predetermined portion of the recess 5a. When the slide knob 2a is slid, the operation-side inclined surface 5g and the shaft member 11 are formed. The operation side inclined surface 12 can be confronted.

  Here, the interlocking member 5 according to the present embodiment is assembled by inserting a swinging shaft L formed to protrude from the handle switch case 1 toward the terminal plate 6 into the insertion hole 5d. It can be swung around the swing axis L in conjunction with the sliding operation of the slide knob 2a and the pushing operation of the push button 2b. On the other hand, as shown in FIG. 8, the arm portion 5f extends in a predetermined direction from the swing axis L, and a groove portion 5c for attaching the movable contact 7 along the extending direction of the arm portion 5f. Is formed. As a result, the movable contact 7 swings in the same direction as the interlocking member 5 swings.

  As shown in FIG. 12, when the slide knob 2a is in the neutral position, the movable contact 7 has one end in contact with the ground contact g and the other end substantially in the middle of the pair of fixed contacts 8 as shown in FIG. It is located and is in a state separated from any fixed contact 8. In this state, the blinkers on both the left and right sides of the motorcycle are not blinking. When the slide knob 2a is slid to the right from the neutral position, the interlocking member 5 swings clockwise about the swing axis L, and as shown in FIG. While the contact with the earth contact g is maintained, the other end contacts the one fixed contact 8 to blink the right blinker, and when the slide knob 2a is slid from the neutral position to the left, the interlocking member 5 swings. As shown in FIG. 5C, the movable contact 7 is kept in contact with the ground contact g while the other end is in contact with the other fixed contact 8 as shown in FIG. The blinker on the left is blinking.

  Further, if the push button 2b is pushed in after the slide knob 2a is slid in either the left or right direction, the operation side inclined surface 12 and the operated side inclined surface 5g face each other. In this state, the shaft member 11 moves in the longitudinal direction, and the movable contact 7 can be separated from the fixed contact 8 by interlocking the interlocking member 5 by the cam action by the operation-side inclined surface 12 and the operated-side inclined surface 5g. It has become.

  Note that a housing hole for housing the coil spring S4 is formed in the protruding portion 5e of the interlocking member 5, and the ball 10 biased by the coil spring S4 is assembled. The coil spring S4 and the ball 10 can maintain a swinging state of the interlocking member 5 by a sliding operation of the slide knob 2a, and constitute a moderation providing unit that provides a moderation when the slide knob 2a is slid left and right. doing.

  Further, a convex portion 13 is formed on the handle switch case 1 along the movement trajectory of the ball 10 accompanying the swing of the interlocking member 5, and the interlocking member 5 is in the initial state in the convex portion 13. The insertion recess 13a for inserting the ball 10 when in position, the insertion recess 13b for inserting the ball 10 when swinging clockwise, and the insertion recess for inserting the ball 10 when swinging counterclockwise 13c is formed.

  That is, when the slide knob 2a is in the neutral position, as shown in FIG. 11A, the interlocking member 5 is in the initial state, and the ball 10 is inserted into the insertion recess 13a. Then, for example, when the slide knob 2a is slid to the right, the interlocking member 5 in the initial state swings about the swinging shaft L, and the state shown in FIG. It is assumed that it is inserted. Thereby, in the swinging process of the interlocking member 5, the ball 10 is detached from the insertion recess 13 a and is inserted into the adjacent insertion recess 13 b, so that moderation can be given during the sliding operation of the slide knob 2 a and the interlocking operation is performed. After the member 5 swings, the ball 10 is inserted into the insertion recess 13b, so that the swinging state is maintained.

  When the operating force on the slide knob 2a is loosened in such a state, the swinging state of the interlocking member 5 is maintained as shown in FIG. 3C, while the slide knob 2a is neutralized by the biasing force of the coil spring S1. It will be returned to the position. In this state, the movable contact 7 is in contact with one fixed contact 8 (see FIG. 12B). For example, the right blinker can be blinked and one (left side in the figure). The operation-side inclined surface 12 and one (left side in the figure) operated-side inclined surface 5g face each other. When the slide knob 2a is slid to the left, the other (right side in the figure) operation side inclined surface 12 and the other (right side in the figure) operated side inclined surface 5g face each other. .

  Thereafter, as the push button 2b is pushed in, the shaft member 11 moves in the longitudinal direction. As shown in FIG. 4D, the cam is formed by the operation side inclined surface 12 and the operated side inclined surface 5g. As a result, the interlocking member 5 can be interlocked to return to the initial state. As a result, the movable contact 7 can be separated from the one fixed contact 8 to reach an intermediate position with the other fixed contact 8, and blinking of the blinker can be canceled (flashing stopped). However, even in the canceling operation process, the ball 10 is removed from the insertion recess 13b and is inserted into the adjacent insertion recess 13a, so that a moderation can be given during the sliding operation of the slide knob 2a and the interlocking member 5 can be swung. After the movement, since the ball 10 is inserted into the insertion recess 13a, the initial state is maintained. Even when the slide knob 2a is slid to the left, a series of actions similar to the above are exhibited.

  Furthermore, in the turn signal switch according to the present embodiment, guide means for guiding the pushing operation of the operation knob 2 (push button 2b) is provided. As shown in FIG. 10, the guide means comprises an insertion hole 6a formed in the terminal plate 6, and when the slide knob 2a is in the neutral position after sliding the slide knob 2a in either the left or right direction. When the push button 2b is pushed in, the distal end portion 11a of the shaft member 11 can be inserted into the insertion hole 6a.

  Thus, when the push button 2b is pushed in to cancel blinking of the blinker, the distal end portion 11a of the shaft member 11 is inserted into the insertion hole 6a, and the longitudinal direction of the push button 2b is restricted while restricting the radial movement thereof. Since the movement in the (axial direction) is guided, operability can be improved. In addition, even if the position of the front-end | tip part 11a of the shaft member 11 and the insertion hole 6a slip | deviates slightly at the time of pushing operation of the push button 2b, the shape of the front-end | tip part 11a of the shaft member 11 in this embodiment is formed in a taper shape. The tip 11a may be securely and smoothly inserted into the insertion hole 6a. Moreover, it is good also as an insertion recessed part which becomes a bottomed shape instead of the insertion hole 6a of this embodiment.

  Furthermore, the guide means according to the present embodiment has a groove shape 6b that extends linearly in the left-right direction from the insertion hole 6a (or the insertion recess), and with the sliding operation of the slide knob 2a by the groove shape 6b. The tip portion 11a of the moving shaft member 11 can be guided. That is, the tip end portion 11a of the shaft member 11 is inserted into the groove shape 6b, and the movement of the shaft member 11 accompanying the sliding operation of the slide knob 2a is guided, and the substantially center of the groove shape 6b. An insertion hole 6a (or an insertion recess) is formed in the.

  Thus, the sliding movement of the slide knob 2a can be guided by guiding the movement of the shaft member 11 in the left-right direction by the groove shape 6b, and the length of the shaft member 11 can be increased by the insertion hole 6a (or the insertion recess). By guiding the movement of the direction, it is possible to guide the push-in operation of the push button 2b, and it is possible to improve the operability of both the sliding operation and the pushing operation. Moreover, in this embodiment, since the insertion hole 6a (or insertion recessed part) and groove shape 6b which comprise a guide means are formed in the terminal board 6, the separate new component for arrange | positioning a guide means is provided. It can be unnecessary.

  According to the above-described embodiment, the interlocking member 5 can swing around the predetermined swing axis L in conjunction with the sliding operation and the pushing operation of the operation knob 2, so that the operation knob 2 (slide knob 2a) ), The movable contact 7 of the interlocking member 5 can be operated relatively large, and the movable contact 7 can be reliably brought into or out of contact with the fixed contact 8. In particular, in the present embodiment, the distance between the operation knob 2 (shaft member 11) and the swing axis L of the interlocking member 5 (dimension X in FIG. 11A) is fixed to the fixed contact 8 of the movable contact 7. The dimension between the contact portion and the swing axis L of the interlocking member 5 (dimension Y in FIG. 11A) is set larger (X <Y). Thereby, it is possible to easily and surely move the movable contact 7 in accordance with the sliding operation of the operation knob 2 (slide knob 2a), and the movable contact 7 is brought into contact with or separated from the fixed contact 8. Furthermore, it can be performed reliably.

  The push button 2b has an operation-side inclined surface 12 that can be opposed to the operated-side inclined surface 5g formed on the interlocking member 5 by a sliding operation of the slide knob 2a, and the operation-side inclined surface 12 during a push-in operation. Since the movable contact 7 can be separated from the fixed contact 8 by interlocking the interlocking member 5 by the cam action by the operated side inclined surface 5g, the blinker blinking can be canceled with a relatively simple configuration. be able to.

  In particular, in the present embodiment, the operation-side inclined surface 12 and the operated-side inclined surface 5g are formed in a curved shape following the swinging locus of the interlocking member 5, as shown in FIGS. In other words, the surfaces (facing surfaces) acting as cams on the operation-side inclined surface 12 and the operated-side inclined surface 5g are curved surfaces having the same curvature as the swing locus of the interlocking member 5. As a result, when the push button 2b is pushed in, the operation-side inclined surface 12 can be satisfactorily brought into contact with the operated-side inclined surface 5g, and the cam action can be reliably achieved. Therefore, the pushing operation force of the push button can be more reliably transmitted to the interlocking member, and the blinker can be canceled more reliably and smoothly.

  Further, according to the present embodiment, the push button 2b is formed by protruding the shaft member 11 inserted through the interlocking member 5, and the operation member inclined surface 12 is formed on the shaft member 11, so that the slide knob The interlocking member 5 can be swung reliably and smoothly during the push-in operation of the push button 2b while allowing the interlocking member 5 to swing according to the sliding operation 2a. Further, the interlocking member 5 is formed on the interlocking member 5 and can hold the swinging state of the interlocking member 5 by the sliding operation of the operation knob 2 (slide knob 2a). Since the moderation means for imparting moderation during the dynamic operation is provided, it is possible to further improve the operability during the left / right sliding operation of the operation knob (slide knob 2a).

  Although the present embodiment has been described above, the present invention is not limited to this, and includes, for example, guide means (insertion hole 6a and groove shape 6b) for guiding the pushing operation of the operation knob 2 (push button 2b). In addition to the moderation applying means comprising the coil spring S4 and the ball 10, the interlocking member 5 can be kept in the swinging state by the sliding operation of the slide knob 2a, and the moderation can be controlled when the slide knob 2a is slid right and left. It is good also as what comprised the moderation provision means of the other form to provide.
