Abstract

PURPOSE:To surely prevent unprepared simultaneous operation of two switches with a simple structure by arranging a check fitting by which in the case of displacing one switch operating piece, associated with this displacement, displacing the other switch operating piece is impeded. CONSTITUTION:When an operating knob 12 is not operated, a check fitting 21 is placed in a neutral condition, and in this condition, the operating knob 12 is operated to diaplace a switch operating piece 13D in a Y-axis direction through a drive piece 10D. Then, a front lifter operation is performed by a built-in switch 6D, and the check fitting 21 is associated with the operating piece 13D, to move to a side of the operating piece 13D in an X-axis direction. Since a restricting surface 21f of the check fitting 21 is brought into contact with a tapered surface of a switch operating piece 13B, displacing this switch operating piece 13B in the Y-axis direction is impeded. Thus, the switch operating pieces 13B, 13D can not be simultaneously displaced in the Y-axis direction, so that simultaneously performing rear/front lifter operations can be surely prevented.

Such a simultaneous operation is more likely to occur as the operation knob 12 and the like are made smaller by making the switch device compact and the like. Therefore, there is a demand for a device capable of preventing the above simultaneous operation without significantly modifying the conventional switch device.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a switch device which can reliably prevent two switch operation pieces from being simultaneously operated accidentally by a simple structure. Has an aim.

[0008]

In order to achieve the above object, a switch device according to the invention of claim 1 corresponds to a plurality of built-in switches arranged side by side in a switch case, and these built-in switches respectively. And a plurality of drive pieces that are operated by an operation knob outside the switch case and the built-in switch, respectively, and are displaced in a predetermined direction by the drive pieces during operation. In this case, a plurality of switch operation pieces for operating the built-in switches corresponding to the drive pieces are provided, and among the plurality of switch operation pieces, in a direction orthogonal to the juxtaposed direction of the built-in switches in the same plane. Between two displaceable switch operating pieces, when one of the switch operating pieces is displaced, in conjunction with this, a restraint device that prevents the other switch operating piece from displacing. It is obtained by movably disposed along the arrangement direction.

According to a second aspect of the present invention, there is provided a switch device in which a plurality of built-in switches arranged in parallel in the switch case are provided, and the built-in switches are provided so as to correspond to the built-in switches, respectively. A plurality of drive pieces operated by the operating knob and the built-in switches are arranged corresponding to the respective built-in switches, and the built-in switches corresponding to the drive pieces are operated when the drive pieces are moved in a predetermined direction during operation. A plurality of switch operating pieces for causing the built-in switches to be arranged side by side and having a displacement direction different from each other in a direction orthogonal to the side by side in the same plane.
One of the two adjacent switch operation pieces is connected to one end side of the plate-like check device in the above-mentioned juxtaposed direction, and when one switch operation piece is displaced to the other end side of the check device, the other switch is operated. A check hole is formed to prevent the displacement of the operation piece, and to prevent the displacement of the one switch operation piece via the check tool when the other switch operation piece is displaced.

[0010]

According to the first aspect of the present invention, the checker is arranged between the two switch operation pieces which are respectively displaceable in the directions orthogonal to each other in the same plane as the direction in which the built-in switches are arranged in parallel. Since the switch operating piece is displaced, when the one switch operating piece is displaced, the check piece is moved to the other switch operating piece side by the switch operating piece and the displacement of the switch operating piece is prevented. Therefore, even if there is an inadvertent operation by the operation knob, simultaneous operation in which both switch operation pieces are simultaneously displaced is prevented. Here, it is sufficient to use all the configurations of the switch device that have existed in the related art as they are and to additionally dispose the above-mentioned restraint device newly, so that the structure is not complicated and the cost is not significantly increased.

According to the second aspect of the present invention, the two adjacent switch operation pieces having different displacement directions in the direction in which the built-in switches are arranged in parallel and in the direction orthogonal to the direction in which they are arranged are different from each other. On the other hand, one end side of the restraint was connected, and the check hole was formed at the other end of this restraint, so when one switch operation piece was displaced, the restraint was also displaced in the same direction. Displacement of the other switch operation piece is blocked at the check hole, and when the other switch operation piece is displaced,
The restraint hole portion prevents the restraint device from moving, which prevents displacement of one of the switch operation pieces. Therefore,
Even if there is an inadvertent operation by the operation knob, simultaneous operation in which both switch operation pieces are simultaneously displaced is prevented.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing an example in which a switch device according to an embodiment of the present invention is applied for position control of an electric seat, FIG. 2 is a bottom view showing a part of the switch device omitted, and FIG. It is a side view which fractures | ruptures and shows a switch apparatus partially. In these figures, the same parts as those of the conventional one shown in FIG. 13 are designated by the same reference numerals, and detailed description thereof will be omitted.

1 to 3, a switch operation piece 13B corresponding to the built-in switch 6B for operating the rear lifter,
Between the switch operation piece 13D corresponding to the built-in switch 6D for operating the front lifter, a pair of main side portions 21a, 21b parallel to each other along the X-axis direction and a pair of main side portions 21a and 21b parallel to each other along the Y-axis direction. A frame-shaped restraint 21 including a pair of connecting sides 21c and 21d integrally connecting the main sides 21a and 21b is disposed so as to be displaceable in the X-axis direction. At one of the inner corners of the main sides 21a and 21b, one switch operation piece 13B (13
When D) is displaced in the Y-axis direction, the switch operation piece 13B
When pressed by (13D), the other switch operation piece 13D (1
3B) side tapered surface 13e (21f) that comes into contact with each tapered surface 13d (13b) and prevents displacement in the same direction as the switch operation piece 13B (13D), that is, in the Y-axis direction.
Are formed respectively.

Reference numerals 22 and 22 are a pair of projections integrally formed on both ends of the main sides 21a and 21b of the restraint device 21 in the X-axis direction, and 23 and 23 are formed on the case body 2 side. It is a guide hole that guides the movement of the restraint device 21 in the X-axis direction via the protrusions 22, 22.

In the switch device having the above-described structure, the basic switch operation by operating the operation knobs 11 and 12 is the same as the conventional one, and the description thereof will be omitted here. When the operation knob 12 is not operated, the restraint device 21 is in a neutral state as shown in FIG. From this neutral state, the operation knob 1
2 is operated to operate the switch operation piece 13 via the drive piece 10D.
When D is displaced in the Y-axis direction as shown in FIG. 5, the built-in switch 6D performs the front lifter operation. At this time, the restraint device 2 is operated by the switch operation piece 13D.
1 moves to the switch operation piece 13D side in the X-axis direction, and the restricting surface 21f of the restraining device 21 causes the switch operation piece 13 to move.
Since it abuts on the tapered surface 13b of B, the displacement of the switch operating piece 13B in the Y-axis direction is prevented.

Further, from the neutral state, the operation knob 12 is operated to operate the switch operation piece 13B via the drive piece 10B.
As shown in FIG. 6, when it is displaced in the Y-axis direction, the built-in switch 6B causes the rear lifter operation. At this time,
The switch operation piece 13B moves the restraint device 21 to the switch operation piece 13D side in the X-axis direction, and the regulation surface 21e of the restraint tool 21 contacts the tapered surface 13d of the switch operation piece 13D. The displacement of the piece 13D in the Y-axis direction is prevented. That is, both of the switch operation pieces 13B and 13D cannot be simultaneously displaced in the Y-axis direction, so that the rear lifter operation and the front lifter operation are reliably prevented from being simultaneously operated. Here, the basic structure of the conventional switch device is left as it is, and it suffices to additionally dispose the restraint device 21 between the two switch operation pieces 13B and 13D, which makes the structure complicated and significantly increases the cost. The above-mentioned simultaneous operation preventing function can be easily imparted without inviting.

7 to 9 show another embodiment of the present invention, in which a switch operation piece 13A which is displaceable in the X-axis direction for reclining operation and a switch operation piece which is displaceable in the Y-axis direction for rear lifter operation are shown. It is designed to prevent 13B from being displaced at the same time.

In FIGS. 7 to 9, reference numeral 31 is a plate-like restraining device which is arranged so as to straddle between the switch operating piece 13A and the switch operating piece 13B adjacent to the switch operating piece 13A. The fitting hole 32 formed on one end side in the X-axis direction is fitted to the switch operating piece 13A, for example, and is integrally connected to the switch operating piece 13A. Further, on the other end side of the restraint device 31 in the X-axis direction, there are restricting surfaces 33a and 33a for preventing the switch operation piece 13B from being displaced in the Y-axis direction when the switch operation piece 13A is displaced, and the Y of the switch operation piece 13B. Restriction surfaces 33b and 3 for preventing the switch operation piece 13A from being displaced in the X-axis direction when the switch operation piece 13A is displaced in the axial direction.
3b is formed to form a check hole portion 33.

That is, in the switch device having the above structure, when the operation knobs 11 and 12 are not operated, the restraint device 3
1 is in a neutral state as shown in FIG. In this neutral state, when the operation knob 11 is operated to displace the switch operation piece 13A in the X-axis direction via the drive piece 10A as shown in FIG. 11, the built-in switch 6A performs the reclining operation. At this time, the switch operation piece 1
Since the restraint device 31 is also displaced in the X-axis direction integrally with 3A, and the regulation surfaces 33a, 33a in the restraint hole portion 33 abut on both sides in the Y-axis direction of the switch operation piece 13B, the Y-axis of the switch operation piece 13B. The displacement in the direction is blocked, and the rear lifter operation is not performed.

Further, from the neutral state, the operation knob 12
To operate the switch operation piece 13B via the drive piece 10B.
12, is displaced in the Y axis direction, the rear lifter operation is performed by the built-in switch 6B. At this time, since both sides of the switch operation piece 13B in the X-axis direction abut on the restriction surfaces 33b and 33b in the check hole portion 33, the displacement of the other switch operation piece 13A in the X-axis direction is prevented via the check tool 31. Therefore, the reclining operation is not performed. That is, in this example, the restraint device 3 is
By 1, the simultaneous operation of the reclining operation and the rear lifter operation is prevented. In the case of this embodiment as well, the restraint device 31
Need only be arranged across one switch operation piece 13A and the other switch operation piece 13B, so that the simultaneous operation prevention function can be achieved without inviting a complicated structure and a significant increase in cost. Can be given.

Although the above embodiments have been described as being applied to the position control of the electric seat, they can also be applied to the position control of other devices in a plurality of directions.

[0022]

As described above, claim 1 and claim 2 are as follows.
According to the invention, one of the two specified switch operation pieces of the plurality of switch operation pieces corresponding to the plurality of built-in switches arranged in parallel with each other is displaced and at the same time the other switch operation piece is displaced. Since a restraint device to prevent is provided, even if an inadvertent operation with the operation knob is performed,
It is possible to prevent the two switch operation pieces from displacing at the same time, and it is possible to prevent simultaneous operation while using the existing switch structure as it is with a simple structure and low cost.
