Further, by providing a separate switch device, the number of parts is increased, the number of steps for manufacturing an automobile is increased, and further, the weight reduction of the automobile is hindered.

Therefore, it is an object of the present invention to provide a switch device that can operate different mechanisms with one operation switch and does not need to provide a separate switch device.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, the knob of the switch device is provided with a guide portion extending in an appropriate direction, and a slider slidable along the guide portion is engaged with the guide portion. The switch mechanism is interlocked with this slider by sliding in a direction substantially perpendicular to the extension direction of the guide portion with which the slider engages, and the knob is attached to the guide portion in the extension direction. By moving in the right angle direction, the slider that engages with this guide part slides in the same direction as the moving direction of the knob, and the switch mechanism that works with this slider operates to move the knob into the guide part. By moving in a direction other than a direction substantially perpendicular to the extending direction, the slider engaging with the guide part slightly slides in a direction substantially perpendicular to the extending direction of the guide part due to the movement of the guide part. Or almost Without the switch mechanism interlocked with the slider proposes a switch device being characterized in that a structure does not work.

[0007]

[Action]

 For example, the guide portion of the knob can be constituted by a vertical guide portion extending substantially vertically and a horizontal guide portion extending substantially horizontally. The operation of the switch device equipped with the above knob will be described below.

When the operator pushes the knob in a substantially vertical direction, the slider engaged with the horizontal guide portion is slid downward, and the switch mechanism interlocking with the slider is operated to appropriately interrupt the circuit. Be done. At this time, since the vertical guide portion is moved in this extending direction, the slider engaged with the vertical guide portion is not slid by the vertical guide portion, and the slider hardly moves. Therefore, the switch mechanism interlocking with this slider is not operated.

On the other hand, when the operator moves the knob in a substantially horizontal direction, the slider engaged with the vertical guide is slid in a substantially horizontal direction, and the switch mechanism interlocking with the slider is operated to operate an appropriate circuit. Is intermittent. At this time, since the horizontal guide portion is moved in the same horizontal direction as this extending direction, the slider engaged with the horizontal guide portion is not slid and the slider hardly moves. Therefore, the switch mechanism interlocking with the slider is not operated.

By fitting the switch case 12 from above the switch base 16 in this state, the switch device 10 is completed as shown in FIG.

When the switch device 10 is not operated, as shown in FIGS. 3A, 4 and 7A, the urging spring 28 pushes the cam ball 30 upward, and the cam ball 30 moves. Is engaged with the cam apex portion 14c of the knob 14, and the knob 14 is pushed upward at approximately the center of the knob accommodating portion 12d.

At this time, the lower end of the engaging portion 20c of the guide plate 20 of the knob 14 is engaged with the guide rail 12m of the switch case 12 to prevent the knob 14 from jumping upward. Then, as shown in FIGS. 4 and 5, the slider 22 engaged with the guide plate 20 is in contact with the slider guide portion 16e of the switch base 16, and the contact portion 24a of the movable contact piece 24 of the slider 22 is It is pressed against the fixed contact 18b of the printed circuit board 18.

The operation of the embodiment of the switch device 10 according to the present invention configured as described above will be described below. The switch device 10 is attached at an appropriate position on the interior panel of the automobile, and the tilt mechanism and the slide mechanism of the roof panel of the automobile are operated by operating the switch device 10.

For example, when operating the tilt mechanism of the roof panel, the knob 14 is pushed almost vertically. As shown in FIG. 7B, the cam ball 30 engaging with the cam apex portion 14c is pushed against the urging force of the urging spring 28, and the lower end surface of the edge portion 14a of the knob 14 is moved to the knob accommodating portion 12d. Abutted against.

Then, as shown in FIG. 3 (b), the horizontal hole 20 b of the guide plate 20 is moved downward, so that the slider 22 engaged with the horizontal hole 20 b is slid downward and the slider 22 is slid downward. The movable contact piece 24 fixed to 22 is connected to the fixed contact 18b, the switch device 10 is turned on, and the tilt mechanism of the roof panel operates.

If a circuit that causes the LED 26 to emit light when the switch device 10 is turned on is set, the emitted light will pass through the inside of the illumination hole 12e and the light shielding wall 12f, as shown in FIG. Only the inside of the knob 14 is illuminated without passing through the edge 14a of the knob 14 to the outside. Therefore, the semi-transparent mark provided on the upper surface of the knob 14 emits light, and the operation of the switch can be confirmed.

Further, as shown in FIG. 3B, when the knob 14 is pushed in, the vertical hole 20a of the guide plate 20 is also moved downward, but the slider 22 engaged with this vertical hole 20a is Since sliding in the vertical direction is restricted by the slider guide portion 16e shown in FIG. 5, the slider 22 does not move in either direction.

Further, as shown in FIG. 3B, when the knob 14 is pushed in such a manner that the knob 14 is slid in the horizontal direction while being pushed in, the edge portion 14a of the knob 14 is moved to the knob accommodating portion 12d. The movement of the knob 14 is restricted by abutting the side of the step on the end. Therefore, it is prevented that the knob 14 is slid in the horizontal direction while being pushed.

When the biasing force that pushes the knob 14 is released, as shown in FIG. 7B, the cam ball 30 pushed up by the biasing bar 28 pushes the knob 14 upward, and the guide plate 20 moves. The knob 14 is moved upward and returned to its original position until the lower end of the engaging portion 20c comes into contact with the guide rail 12m. At this time, as shown in FIG. 3B, the slider 22 engaged with the horizontal hole 20b of the guide plate 20 is also slid upward, and the movable contact piece 24 fixed to the slider 22 and the fixed contactor 18b. The switch device 10 is turned off by the separation.

On the other hand, when the roof panel slide mechanism is operated, the knob 14 is slid in either a substantially horizontal direction depending on whether the roof panel is open or closed. As shown in FIG. 7C, the cam ball 30 is pushed against the biasing force of the biasing spring 28 by the inclined surface of the cam portion 14b, and as shown in FIG. The end is brought into contact with the end of the guide plate hole 12i.

Then, the vertical hole 20a of the guide plate 20 moves laterally, so that the slider 22 engaged with the vertical hole 20a slides in the same direction, and the movable contact fixed to the slider 22 is attached. The piece 24 is connected to the fixed contact 18b, the switch device 10 is turned on, and the sliding mechanism of the roof panel is operated.

Further, when the knob 14 is slid, the horizontal hole 20b of the guide plate 20 is also moved laterally. However, the slider 22 engaged with the horizontal hole 20b has the slider guide portion 16e shown in FIG. As a result, the slider 22 is not moved in either direction, because the sliding to the side is restricted.

Further, as shown in FIG. 3C, when the knob 14 is urged to be pushed downward with the knob 14 slid, the edge portion 14a of the knob 14 is moved to the end portion of the knob accommodating portion 12d. Since the movement of the knob 14 is restricted by coming into contact with the upper part of the step, the knob 14 is prevented from being pushed downward while being slid in the horizontal direction.

When the biasing force that slides on the knob 14 is released, as shown in FIG. 7C, the cam ball 30 pushed up by the biasing bar 28 pushes the slope of the cam portion 14b upward, Since the upward movement of the knob 14 is limited by the engagement between the engaging portion 20c of the guide plate 20 and the guide rail 12m, the knob 14 moves in the direction opposite to the sliding direction, and the cam ball 30 moves. The cam portion 14b slides until it engages with the cam apex portion 14c, and is returned to the original position.

At this time, as shown in FIG. 3 (c), the slider 22 engaged with the vertical hole 20 a of the guide plate 20 is also slid in the same direction and the movable contact piece 24 fixed to the slider 22. The fixed contact 18b is separated, the switch device 10 is turned off, and the operation of the sliding mechanism of the roof panel is stopped.

Therefore, according to the present embodiment, the guide portion of the knob 14 is constituted by the vertical hole 20a and the horizontal hole 20b, and the extending directions of the vertical hole 20a and the horizontal hole 20b are substantially right angles. ing. The slider 22 engaged with the vertical hole 20a and the horizontal hole 20b is slid in only one direction by the slider guide portion 16e of the switch base 16.

Therefore, when the knob 14 moves in one direction, only the slider 22 engaged with the guide portion perpendicular to this direction slides, and the other sliders 22 move in any direction. Therefore, the switching of the switch mechanism corresponding to each moving direction of the knob 14 is reliably performed, and no malfunction occurs.

Further, in this embodiment, the switch mechanism interlocked with each slider 22 is composed of a movable contact piece 24 fixed to the slider 22 and a fixed contact 18 b arranged on the printed board 18. Therefore, the operation is reliably performed with the minimum number of parts.

Further, according to the present embodiment, the cam portion 14b is provided on the edge portion 14a of the knob 14, and the cam portion 14b is pressed upward by the cam ball 30 and the biasing spring 28. The same biasing spring 28 can perform the returning movement of the position with respect to the vertical movement and the returning movement of the position with respect to the horizontal sliding. For this reason, it is not necessary to provide a separate biasing vane for returning the position with respect to the movement of the knob 14 in each direction, and the number of parts does not increase.

Further, in this embodiment, since the step is formed at both ends of the knob accommodating portion 12d of the switch case 12, it is possible to slide the knob 14 in the horizontal direction when pushing it in, or in the horizontal direction. It is prevented from pushing downwards while sliding on. Therefore, only one operation of the switch mechanism is performed, and erroneous operation is prevented even when the switch device 10 is manually operated.

In this embodiment, the guide plate 20 of the knob 14 is provided with the vertical hole 20a and the horizontal hole 20b, and the slider 22 is formed with the boss portion 22a. Although the structure in which the knob 22 and the slider 22 are slidable is adopted, other structures may be used as long as the structure in which the knob 14 and the slider 22 are slidable with respect to each other.

For example, the guide plate 20 may be formed with a boss portion as a guide portion, and the slider 22 may be provided with a guide hole extending in an appropriate direction. Therefore, it is possible to select an appropriate structure depending on the relationship with other parts and design convenience, and it is possible to obtain a switch device having a more rational structure.

Further, in the present embodiment, the structure of the switch device suitable for operating the roof panel of the automobile has been described, but the structure may be suitable for other industrial products. In any case, the effect of the present embodiment is not impaired such that the number of parts can be reduced.

Further, in the above-described embodiment, two sets of return members including the biasing springs 28 and the cam balls 30 are provided on the lower portions of both sides of the knob 14, but even one set of return members may be provided. Good.

[0053]

As described above, according to the switch device of the present invention, the knob is provided with the guide portion extending in the appropriate direction, and the slider is engaged with the guide portion and the slider is engaged. Since the switch mechanism that operates by sliding in a direction substantially perpendicular to the extension direction of the guide part is linked, a separate switch mechanism is operated for each direction of knob operation. Therefore, one switch device can operate a plurality of operations, and the number of switch devices such as mechanical products having a plurality of operating mechanisms can be reduced, which facilitates the manufacture of mechanical products and the like. As a result, the manufacturing cost can be reduced.

Further, by moving the knob in a direction substantially at right angles to the extending direction of the guide portion, the slider engaging with the guide portion slides in substantially the same direction as the moving direction of the knob, Since the interlocking switch mechanism is operated, the switch mechanism operated by one movement of the knob can be limited to any one. Therefore, only one operation of the mechanism connected to each switch mechanism can be selected according to the operation direction of the knob, and the operator's erroneous operation can be prevented.

Furthermore, since the angle of each guide portion of the knob can be set appropriately, for example, a switch device having a structure for moving the knob in the vertical direction and the horizontal direction, or a structure for pushing the knob in a plurality of diagonal directions. The switch device or the like can be configured, and can be widely applied to a mechanism such as a product to which the switch device is attached.
