Abstract

PURPOSE: To provide a two steps operation switch device in which miniaturization of whole the device and reduction of the number of partitems can be achieved. CONSTITUTION: A follower 6 is made interlocked with an operating knob 5 and rotated through the first nodal mechanism 8 by making an operating knob 5 counterclockwise rotate so as to make a down switch turned 'on' which is defined 'the first switch', and a down switch is made operatied 'on' by means of this follower 6. This is the first step of rotational operation of the operating knob 5. Secondly, the operating knob is futher rotated from that condition so as to make an auto switch turned 'on'. Then, the operating knob 5 is relatively rotated to against the follower 6 opposite to the holding force due to the first nodal mechanism 8 after the follower 6 makes the down switch 14 turned 'on' and is made stopped. Thereby, the auto switch is made turned 'on' by means of one projected part 5d of an extending piece 5b of the operating knob 5. This is the second step rotational operation of the operation knob.

Next, the operation will be described.

First, as shown in FIG. 4, FIG. 5, and FIG. 6A, the operation knob 5 is pressed from above as indicated by the arrow to rotate the operation knob 5 counterclockwise about the rotary shaft 7. When the rotary operation is performed, the follower 6 is rotated counterclockwise integrally with the operation knob 5 via the moderation mechanism 8. Thereby, first, the first push rod 11 is pressed by the pressing piece 6b of the follower 6, and the bulging projection 14a of the down switch 14 is displaced downward against the elastic force. As a result, the bulging protrusion 14a is elastically deformed to generate a click feeling, the movable contact 14b is brought into contact with the fixed contact 14c, the down switch 14 is turned on, and the rotation of the follower 6 is stopped. In this way, the protruding protrusion 14a of the down switch 14
Since a clicking sensation is generated when is elastically deformed, the operator confirms that the down switch 14 is turned on through a sound or a hand. In this case, the control circuit 5
5, the output terminal of the control circuit 55 goes to a low level only while the down switch 14 is on, the switching transistor 56 is turned on, and a current flows through the exciting coil 51d, and the two fixed terminals 51a and 51b. The space is closed by the movable contact piece 51c, and the DC motor 50 is driven. In this way, by rotating the operation knob 5 in the first stage, the window panel descends only while the operation knob 5 is being pressed.

In this state, the auto switch 17 side has the second push rod 1 as shown in FIG. 6 (a).
Since the upper end of 6 is located between both protrusions 5d of the operation knob extension piece 5b, the auto switch 17 is not turned on.

Then, when the operation knob 5 is further rotated, the operation knob 5 is relatively rotated counterclockwise with respect to the follower 6 against the holding force of the detent mechanism 8. The ball 10 of No. 8 sinks into the spring force of the spring 9 and separates from the moderation groove 5a, and a click feeling occurs (see FIG. 4B). In this state, as shown in FIG. 6B, the second protrusion is formed by the one protrusion 5d of the operation knob extension piece 5b.
The push rod 16 is pressed downward, the bulging projection 17a of the auto switch 17 having no click function is elastically deformed, the movable contact 17b is brought into contact with the fixed contact 17c, and the auto switch 17 is turned on. Along with
The rotation of the operation knob 5 stops. In this way, when the ball 10 separates from the moderation groove 5a, a click feeling is generated, so that the operator can confirm that the auto switch 17 is turned on through a sound or a hand.

With the down switch 14 and the auto switch 17 being turned on, the window panel continues to move upward even when the operation knob 5 is released. That is, depending on the ON state, the control circuit 5
The output terminal of 5 is latched at a low level, the switching transistor 56 is turned on, and the exciting coil 51d
A current flows through the movable contact piece 51c between the two fixed terminals 51a and 51b, and the DC motor 50 is driven. As a result, the window panel descends, and along with this descending, a ripple component is generated in the resistor 52 and is extracted by the filter circuit 53 and compared by the comparator 54, but as long as it exceeds the reference value, the control circuit 55. The output terminal of is maintained at the low level and the instruction signal is not output.

However, when the lower end of the window panel comes into contact with the stopper in the door, the load of the DC motor 50 suddenly increases and becomes locked, so that the ripple component becomes smaller and the reference value of the comparator 54 becomes smaller. Will fall below.

As a result, the instruction signal is output from the comparator 54, the latched state of the output terminal of the control circuit 55 is released and switched to the high level, the switching transistor 56 is turned off, and the two fixed contacts 51a of the relay 51, The space between 51b is opened and the DC motor 50 is stopped.

The operation of the window panel is also stopped by operating the operation knob 5 in the opposite direction during the downward movement.

In such a structure, since the follower 6 is arranged in the internal space of the operation knob 5, it is different from the conventional one.
The overall size can be reduced, and the degree of freedom in design layout can be improved as compared with the conventional one.

Further, since the auto switch 17 and the second push rod 16 for pressing the auto switch 17 are provided one by one, the number of parts can be reduced and the cost can be reduced as compared with the conventional case.

Further, FIG. 7 and FIG. 8 show the second embodiment of the present invention.
An example will be described.

In the first embodiment, the down switch 14 and the up switch 15 are used to generate a click feeling when the first stage operation is performed, whereas in this embodiment, the operation knob 5 and the upper case 1 are used. The difference is that the second detent mechanism 20 provided between the first and second positions makes a click feeling when the first stage operation is performed.

Specifically, as shown in FIGS. 7 (b), 7 (d) and FIG. 8, the second detent mechanism 20 has a recess 1a formed in the upper case 1, and the recess 1a is formed in the recess 1a. A ball 22 is placed on the stored spring 21, and the ball 22 is fitted in a moderation groove 5g formed inside the operation knob 5.

With this arrangement, when the first step operation is performed, the ball 22 moves into the moderation groove 5 as shown in FIG. 8 (a).
A feeling of click is generated by leaving the g. Therefore, by providing such a mechanism at one place, the down switch 14 and the up switch 15 as in the first embodiment.
There is no need to provide a click mechanism in the structure, and the structure can be simple.

Although the embodiment of the present invention has been described with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. However, it is included in the present invention. For example, in each of the above embodiments, each moderation mechanism 8 and 20 is formed of the springs 9 and 21, the balls 10 and 22, the moderation grooves 5a and 5g, etc. The member may be detachable from the hole or the like.
