Description

[Detailed Description of the Invention] The present invention includes a button switch that opens and closes in response to a pressing operation of a first operating member, and a second operating member that is formed so as to surround the peripheral side of the first operating member. The present invention relates to a switch device having a configuration including a changeover switch that is switched in response to a rotational operation and a movement operation of a member.

Conventionally, for example, a switch for operating a headlamp cleaner, a switch for lighting a small lamp and a headlamp, and a switch for automatically lighting a headlamp have been provided independently and separately.

However, it is desirable to collect the above-mentioned related switches into one switch mechanism, but in particular, the automatic headlamp lighting changeover switch is rarely used during normal operation, so the operating member must be pressed to avoid erroneous operation. If switching is performed by turning (rotating while being pressed), there is a problem in that the push switch for operating the headlamp cleaner also operates in conjunction with this operation.

The present invention was developed in view of the above circumstances, and its purpose is to completely separate the opening and closing of the push switch by operating the first operating member and the switching of the changeover switch by pushing and turning the second operating member. To provide a switch device in which a push switch and a push-and-turn type rotary switch can be integrated in a convenient manner.

In the switch device of the present invention, a holding member is rotatably attached to a pipe, a first operating member is provided on the holding member so as to be pressable in the axial direction of the pipe, and the first operating member A second operating member that surrounds the peripheral side of the pipe is provided with a supporting portion that supports the second operating member rotatably and axially movably with respect to the pipe, and this supporting portion is connected to the holding member. The first operating member is fitted into a notch formed in the axial direction so as to be movable in the axial direction, thereby preventing the first operating member from being pressed in the axial direction when the second operating member is pressed in the axial direction. It is designed to prevent this.

Hereinafter, an embodiment in which the present invention is applied to a light switch device equipped with a push switch for a headlamp cleaner of an automobile, a switch for switching between a small lamp and a headlamp, and a switch for automatically lighting the headlamp will be described with reference to the drawings. First, in FIG. 1, reference numeral 1 denotes a base body fixed to a steering column of an automobile (not shown), for example, by screwing, and a generally short cylindrical housing portion 2 with one side closed is formed on this base body, and the closed end thereof A circular insertion hole 3 is formed in the center. Reference numeral 4 denotes an insulating member fixed to the open end of the housing portion 2 of the base body 1, and a support hole 5 is formed in this insulating member at a portion opposite to the insertion hole 3. Reference numeral 6 denotes a pipe whose base end is fixed to the support hole 5 of the insulating member 4, and whose tip end protrudes from the insertion hole 3 of the base body 1 to the outside of the storage section 2. Reference numeral 7 denotes a substantially circular holding member that is rotatably inserted into the tip of the pipe 6, and is held from the pipe 6 by an annular member 41 that is engaged and held in a groove 6a formed at the tip of the pipe 6. It is designed to prevent it from falling out. A cylindrical portion 7a having the same axis as the axis of the pipe 6 is formed on the outer circumference of the holding member 7, and as shown in FIGS. First notches 8 are formed to extend in the axial direction at equal intervals, and six second notches 9 are formed between each first notch 8 at equal intervals. One of the second notches 9 is formed wide. In FIG. 1, 10 is a substantially circular first tube made of plastic, for example.
The operating member has, for example, three engaging claws 11 (only one shown in FIG. 1) protruding at equal intervals on its outer periphery, and the engaging claws 11 are connected to the third engaging claws 11 of the holding member 7. 1
By engaging the first operating member 10 in the notch 8 of the holding member 7, the first operating member 10 is moved in the axial direction of the pipe 6 (in the direction of arrow A and the direction opposite to arrow A) between an off position and an on position, which will be described later. is supported so that it can reciprocate. 12 is a substantially cylindrical insulating pusher fitted to the tip of the pipe 6; 13 is this insulating pusher 12;
This is a pin-shaped fixed contact that is fitted inside the pipe 6 via a pusher 14, and is connected to the positive terminal of the battery via a lead wire 13a passed through the pipe 6 and via a motor of a headlamp cleaner (not shown). ing. 15 is a terminal ring attached to a flange 12a formed on the outer periphery of the insulating bushing 12, and this terminal ring is used to connect the lead wire 1 inserted through the pipe 6.
It is grounded via 5a. Reference numeral 16 denotes a compression coil spring installed between the terminal ring 15 and the inner surface of the first operating member 10, and the elastic force of this spring urges the first operating member 10 in the direction of arrow A. It is held in the off position shown in Figure 1.
One end of the compression coil spring 16 is pressed against the terminal ring 15 to be electrically connected to the terminal ring 15, while the other end is bent to face the fixed contact 13 and is connected to the movable contact. 17, whereby the movable contact 17 and the fixed contact 13 constitute a push switch 18. On the other hand, 19 is a rotor inserted into the pipe 6 so as to be rotatable and movable in the axial direction.This rotor has a stepped cylindrical shape having a large diameter portion 19a and a small diameter portion 19b as shown in FIGS. 6 to 8. A pair of ribs 2 are formed on the outer periphery of the large diameter portion 19a.
A rectangular protruding portion 2 is provided such that the ribs 0 and 20 protrude in the diametrical direction and extend outward from one rib 20.
1 is provided in a protruding manner, and a convex portion 22 is provided in a protruding manner on the stepped portion 19c of the large diameter portion 19a and the small diameter portion 19b. Thus, in FIG. 1, 23 is a second operating member,
The outer periphery of this is formed into a substantially cylindrical shape, and on the inner periphery, for example, six support parts 23a (only one is shown in FIG. 1) are formed at equal intervals, and these support parts 23a
An annular fitting portion 23b is formed at the inner peripheral side tip. By fixing the fitting portion 23b to the small diameter portion 19b of the rotor 19 by, for example, press fitting, the second operating member 23 can be rotated around the pipe 6 in the direction of arrow B and the direction opposite to arrow B. and can reciprocate in the axial direction of the pipe 6 (in the direction of arrow A and the direction opposite to arrow A) between a first position and a second position, which will be described later, independently of the first operating member 10. and 6
The support portion 23a of the holding member 7 is inserted into the second notch 9 of the holding member 7.
By fitting the second operating member 23 so as to be movable in the direction of the arrow A and the direction opposite to the arrow A, the outer peripheral portion of the second operating member 23 surrounds the first operating member 10 and the holding member 7. 24 is the rotor 19 and the insulating member 4
A compression coil spring is wound around the pipe 6 and is located between the
The end face portion of the second operating member 23 is pressed against the holding member 7, and the second operating member 23 is urged in the direction of arrow A through the rotor 19, so that the second operating member 23 is always held at the first position shown in FIG. 25 is a moderation mechanism of the second operating member 23, which is a moderation mechanism of the rectangular protrusion 21 of the rotor 19.
A compression coil spring 26 is attached to the compression coil spring 26, and the moderation ball 2 is urged outward by the compression coil spring 26.
7 and moderation recesses 28 to 31 (see FIG. 3) formed on the inner surface of the circumferential wall of the base body 1, which allows the second operating member 23 to be moved to the OFF position and the position shown in FIG. , position and auto position. The rotor 1 is disposed on the inner surface of the peripheral edge of the insertion hole 3 of the base body 1.
As shown in FIG. 3, a rotation regulating recess 32 is formed corresponding to the convex portion 22 of No. 9, and when the second operating member 23 is in the OFF position and from the OFF position to the position indicated by the arrow B. When the rotation operation is performed in the direction, the convex portion 22 is inserted into the rotation regulating concave portion 32.
On the other hand, when the second operating member 23 is operated to the auto position, the rotor 19 and the second
The operating member 23 is moved in the opposite direction of arrow A against the elastic force of the compression coil spring 24 and rotated in the direction of arrow B, and the convex portion 22 is held in the position where it has come out of the rotation regulating recess 32. It is becoming more and more common. 32
is a rotor made of an insulating material, which has a substantially fan shape as shown in FIG. The recesses 35, 35 are formed to face each other, and a rectangular groove 36 (see FIG. 10) is formed extending outward from one of the fitting recesses 35. The rotor 33 is housed in the housing portion 2 of the base body 1 so as to be able to rotate around the pipe 6, and is inserted into the circular hole 34, the pair of fitting recesses 35, and the rectangular groove portion 36, respectively. The large-diameter portion 19a, the pair of ribs 20, 20, and the rectangular protruding portion 21 of the rotor 19 are fitted into the pipe 6 so as to be movable in the axial direction. It rotates together with the operating member 23. The rotor 33 is provided with a pair of movable contacts 37 (only one is shown in FIG. 1), and the movable contacts 37 are connected to a compression coil spring 38,
38 biases toward the insulating member 4 side. On the other hand, the insulating member 4 has fixed contacts for lighting the small lamp, for lighting the headlamp, and for automatically lighting the headlamp, corresponding to the position, position, and auto position of the second operating member 23 (see Fig. 1 for small lamp lighting). Fixed contacts (39, 39 only shown) are fixed, for example, by caulking, and together with the movable contact 37, these fixed contacts constitute a changeover switch 40 consisting of a small lamp switch, a headlamp switch, and an automatic lighting switch. .

Next, the operation of the above configuration will be explained. now,
Assume that the second operating member 23 is in the off position. In this case, when lighting a small lamp or a headlamp (not shown), the second operating member 2
When the rotor 33 is rotated in the direction of the arrow B shown in FIG. When the movable contact 37 is rotated by a predetermined angle and comes into contact with the small lamp fixed contacts 39, 39 or the headlamp fixed contact, the small switch or the small lamp and headlamp switch is turned on, and the small lamp or the small lamp and headlamp are turned on. Ru. At this time, even if a further operating force is applied in the direction of arrow B by mistake to the second operating member 23 that has reached the position, the convex portion 22 of the rotor 19 will not touch the end of the rotation regulating recess 32 of the base body 1. Since the rotor 19 is prevented from rotating in the direction of arrow B due to the contact, the second operating member 23 is prevented from being erroneously rotated to the auto position. Therefore, in order to automatically turn on the headlamp in dark places such as tunnels,
When moving the second operating member 23 to the auto position, first move the second operating member 23 from the first position to the opposite arrow A against the elastic force of the compression coil spring 24.
direction to position it in the second position.
From the first position of the second operating member 23 to the second
The movement to the position is transmitted to the rotor 19 via the support part 23a that moves in the direction of arrow A in the second notch 9 of the holding member 7, and thereby the rotor 19
The convex portion 22 comes out of the rotation regulating recess 32. However, the second operating member 23 is not supported by either the first operating member 10 or the holding member 7, and furthermore, the second operating member 23 is not supported by the first operating member 23 when moving in the opposite direction of arrow A. Since it does not come into contact with the member 10, when the second operating member 23 is moved in the direction opposite to the arrow A, the second operating member 23
In conjunction with this, the first operating member 10 is prevented from being pressed in the opposite direction of arrow A, and therefore, even if the second operating member 23 is pressed, the first operating member 10 is held in the OFF position. Ru. Then, with the second operating member 23 pressed and moved to the second position, arrow B is pressed.
When the second operating member 23 is rotated in the direction, rotation from the second operating member 23 position to the auto position is allowed, and the second
The operating member 23 is placed in the auto position, and the rotor 33 is rotated by a predetermined angle via the rotor 19, so that the movable contact 37 comes into contact with the fixed contact for automatic lighting of the headlamp, and the automatic lighting switch is turned on. , the headlamp is automatically turned on. still,
The supporting portion 23a of the second operating member 23 comes into contact with the side edge of the second notch 9 of the holding member 7 when the second operating member 23 is rotated to the above-mentioned position, position, and auto position. Therefore, the holding member 7 and the first operating member 10 engaged and held by the holding member 7
The second operating member 23 also rotates around the pipe 6, but in this case, the first operating member 10 is always held in the off position, so the second operating member 23
The first operating member 10 is not pressed in conjunction with the operation. On the other hand, when operating the headlamp cleaner, when the first operating member 10 is pressed and moved from the OFF position in the direction opposite to the arrow A against the elastic force of the compression coil spring 16, the movable contact 17 changes to the fixed contact. 13, the push switch 18 is turned on and the headlamp cleaner is operated.

According to this embodiment, the holding member 7 is rotatably inserted and supported by the pipe 6 fixed to the base 1, and the first operating member 10 is inserted into the holding member 7 in the axial direction of the pipe 6. The second operating member 23 is fixed to the rotor 19, which is engaged and held so as to be reciprocally movable, and which is inserted through the pipe 6 so as to be rotatable and movable in the axial direction.
Since the second operating member 23 is configured to be able to rotate around the pipe 6 and move in the axial direction of the pipe 6 independently of the first operating member, the second operating member 23 is moved in the direction opposite to the arrow A. Even if the first operating member 10 is pressed and moved in the direction, the first operating member 10 is held in the off position. As a result, when the second operating member 23 is pressed and moved, the first operating member 10 is interlocked and the push switch is activated. It is possible to prevent problems such as when the switch 18 is turned on against the driver's will. In this case, the support part 2 that supports the second operating member 23
3a is fitted into the second notch 9 of the holding member 7 so as to be movable in the axial direction, so that when the second operating member 23 is pressed, the supporting portion 23a is inserted into the second notch 9 of the holding member 7.
This prevents interference from interfering with the pressing operation. Further, since the holding member 7 is rotatable, when the second operating member 23 is rotated,
The support portion 23a allows the holding member 7 to rotate integrally with the second operating member 23, and the holding member 7 does not hinder the rotation of the second operating member 23.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be applied not only to light switch devices but also to general switch devices equipped with push switches and changeover switches, etc., without departing from the scope of the invention. It can be implemented with various modifications within the scope.

As is clear from the above description, the present invention is a combination of a push switch and a push-and-turn type rotary switch, in which the push-button switch can be opened and closed by operating the first operating member, and the push-and-turn function can be performed by operating the second operating member. The switching of the rotary type changeover switch can be performed completely independently,
It is possible to provide a switch device which has an excellent effect of preventing problems such as when a push switch is turned on against the operator's will due to interlocking of the first operation member when the second operation member is moved.
