Description

[Detailed Description of the Invention] The present invention relates to a switching mechanism operating device configured to individually operate at least a pair of first and second switching mechanisms using operators, and its purpose is to:
When the first operator is operated while the second switching mechanism is operated by the second operator, the operation of the second switching mechanism can be automatically canceled, and the first and second switching mechanisms can be automatically released. It is an object of the present invention to provide an operating device for a switching mechanism that can operate two switching mechanisms individually, thereby simplifying the operation and diversifying the operation modes.

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In Figures 1 and 2, 1 is a case with an opening on one side closed by a lid plate 2, and 3 and 4 are arranged side by side within this case 1 so as to be slidable in the direction of arrow Y and counter-arrow Y. Both of these operators 3 and 4 are biased in the opposite direction of arrow Y by biasing means, for example, compression springs 5, 5, and are integrally attached to one end. It can be pressed in the direction of arrow Y through push buttons 6 and 7 protruding from the sides. Reference numerals 8 and 9 indicate first and second holding means, respectively, which hold the respective operators 3 and 4 in the pushed-in position, and both holding means 8 and 9 are respectively swingably attached to the case 1 and always follow arrows A and B. First and second locking members 1 made of spring wire rods biased in the respective directions
0, 11 and first and second cam protrusions 12, 13 formed on one side of the operators 3, 4. That is, as shown in FIG. 3a, the first cam protrusion 12 has a heart shape surrounded by a heart-shaped cam groove 14 formed on one side of the operator 3, and the cam of this heart-shaped cam groove 14 Specifically, the cam surface (bottom surface) is divided into ``'', ``'', and ``'' as shown in FIG. 3a, so that the cam curve becomes the shape shown in FIG. 4a. '', ``'' has a step between the cam surface ``'' and the cam surface ``'' is a slope. Further, as shown in FIG. 3b, the second cam protrusion 13 has an L-shape surrounded by a heart-shaped cam groove 15 formed on one side of the operator 4; The cam surface (bottom surface) of No. 15 is ``''' as shown in Figure 3b.
When divided into "'", "'", "'", and "'", the cam curve has the shape shown in Figure 4b.
Specifically, the cam surfaces "'", "'", and "'" each have a step difference between them, and the cam surfaces "'", "'" are slopes. On the other hand, each lock member 10, 11 has a coil portion 10a, 11a fitted into a protrusion 1a, 1a protruding from the upper part of the case 1 in FIG. substantially L-shaped bent portions 10b and 11b are formed at the distal end thereof. The locking members 10 and 11 of each of the holding means 8 and 9 constantly urge the bent portions 10b and 11b in the directions of arrows A and B by their own elastic force.
The tip of b, 11b is always the cam protrusion 12, 1
3, the heart-shaped cam groove 14 in the upper part of FIG.
It is in elastic contact with each of the 15 cam surfaces "" and "'".
When the respective operating elements 3 and 4 are pressed by the push buttons 6 and 7, the respective bent portions 10b and 11b of the locking members 10 and 11 are moved into the heart-shaped cam grooves 14 and 15, respectively.
slides along the cam surface of the cam, and finally the cam protrusion 1
2 and 13 to hold the operating members 3 and 4 in the pushed-in position (the movement paths of the bent portions 10b and 11b are shown by arrows C and C' in FIGS. 3a and 3b, respectively).
When the operating elements 3 and 4 are pressed from this held state and moved slightly from the pushed-in position, the bent portions 10b and 11b of the locking members 10 and 11 are moved to the cam protrusion 1.
2, 13 and release the hold on the controls 3, 4.
Thereafter, the operating elements 3 and 4 are moved in the opposite direction of the arrow Y by the compression spring 5, thereby sliding along the cam surfaces of the heart-shaped cam grooves 14 and 15 and returning to their original positions. The movement paths of the bent portions 10b and 11b are shown by arrows D and D' in FIGS. 3a and 3b, respectively). As is clear from the above description, the locking members 10 and 11 configured as described above are swung each time the operating elements 3 and 4 are pressed, and the locking members 10 and 11 are oscillated in response to the oscillation of the operating elements 3 and 4. The operation of holding the button in the pushed-in position and the operation of releasing the holding are alternately repeated. 16 is a first switch mechanism which is a first switching mechanism that is activated when the first operator 3 moves to the push-in position; 17 is activated when the second operator 4 moves to the push-in position. A second switch mechanism is a second switching mechanism, and each of these switch mechanisms 16 and 17 is composed of a plurality of fixed contacts 18 provided on the case 1 side and provided on the operating elements 3 and 4 side, as shown in FIG. It is composed of a movable contact 19. Reference numeral 20 denotes a plate-shaped actuating member, which is held in a guide groove 21 formed in the case 1 so as to be slidable in the left-right direction, and is located between the two operators 3 and 4. The operating member 20 is reciprocated between a left position shown by a solid line in FIG. 1 and a right position shown by a two-dot chain line, and a slope 20a is formed at the lower right corner thereof. There is. A contact element 22 is protruded from one side of the second operating element 4 and is located near the lower part of the cam protrusion 13, and when the operating member 20 is in the right position, When the second operator 4 is pressed in the direction of the arrow Y, the abutting element 22 moves its inclined end surface to the inclined surface 2 of the actuating member 20.
0a to displace the actuating member 20 to the left position. Furthermore, when the first operator 3 is pressed in the direction of arrow Y with the actuating member 20 in the left position, the bent portion 10 of the lock member 10 is moved to the right in response to the pressing operation.
b presses the left side surface of the actuating member 20 to displace the actuating member 20 to the right position. The bent portion 11b of the locking member 11 sinks to the rear in FIG. is positioned so as not to interfere with the movement of the heart-shaped cam groove 15, and protrudes toward the front in FIG. It is positioned so that it can come into contact with the right side surface of the actuating member 20.

Next, the operation when the operating device having the above configuration is applied to, for example, mode switching of an automobile air conditioner will be explained. That is, as is well known, in the case of automobile air conditioners, there are two modes: a defrost mode in which the air from a fan blows against the inside surface of the front window, and a blow mode in which the air is sent into the passenger compartment. At the same time, a different damper is used to switch between the internal air circulation mode and the external air suction mode. Then, such an air conditioner has a first switch mechanism 16.
The defrost mode and the ventilation mode are selected depending on whether the second switch mechanism 17 is activated or not, and the internal air circulation mode and the outside air suction mode are selected depending on whether the second switch mechanism 17 is activated or not. The drive of the blower fan is controlled by a separate switch.

In the state shown in FIG. 1, the first and second switch mechanisms 16 and 17 are inactive, so the ventilation mode and outside air suction mode are selected, and when the ventilation fan is driven in this state, the air is now blown into the vehicle interior. When the first operator 3 is pressed in the direction of the arrow Y using the push button 6 from this state, the bent portion 10b of the first locking member 10 is bent into the cam surface of the heart-shaped cam groove 14.
is moved along the path shown by arrow C in FIG. The actuating member 20 is displaced to the right position. Then, when the pressing operation of the first operator 3 by the push button 6 is released, the operator 3 is slightly moved in the opposite direction of the arrow Y by the spring force of the compression spring 5, thereby locking the bent portion 10b of the locking member 10. engages with the first cam protrusion 12 via the cam surface "" of the heart-shaped cam groove 14 to hold the first operator 3 in the pushed-in position. Then, the first switch mechanism 16 is activated to select the defrost mode, and relatively dry air from outside the vehicle passes through the heater and then becomes warm air and is blown against the inside surface of the front window. In addition, from the state in which the defrost mode and the outside air intake mode are selected (the operating member 20 is in the right position), the second operator 4 is activated by pressing the push button 7.
When pressed in the direction of arrow Y, the bent portion 11b of the second locking member 11 aligns the cam surfaces "'" and "'" of the heart-shaped cam groove 15 along the path shown by arrow C' in FIG. 3b. The abutting element 22, which moves together with the second operator 4 in the final process, is moved by the actuating member 20.
The actuating member 20 is displaced to the left position by coming into contact with the slope of the actuating member 20 . Then, when the pressing operation of the second operator 4 by the push button 7 is released, the operator 4 is pressed against the compression spring 5.
It is moved slightly in the opposite direction of arrow Y by the spring force of
As a result, the bent portions 11b of the locking member 11 are aligned with the cam surfaces "'", "'", "'" of the heart-shaped cam groove 15.
The second cam protrusion 13 is engaged with the second cam protrusion 13 to hold the second operator 4 in the push-in position. Then, the second switch mechanism 17 is activated and the internal air circulation mode is selected, so that a defrost operation is performed using the circulating air in the vehicle interior. On the other hand, when the second operator 4 is pressed in the direction of the arrow Y using the push button 7 from the above-mentioned state in which the ventilation mode and the outside air suction mode are selected and the operation is released, the bent portion 11b of the locking member 11 is pressed. The cam surface of the heart-shaped cam groove 15 is "'", "'", "'", "'", "
'' along the path shown by arrow C' in Figure 3b,
Finally, the bent portion 11b of the locking member 11 engages with the cam protrusion 13 to hold the second operator 4 in the pushed-in position. Then, the second switch mechanism 17 is operated to select the inside air circulation mode, and the air in the vehicle interior is circulated through the blower fan.
Now, when the first operator 3 is pressed in the direction of the arrow Y using the push button 6 from the state in which the ventilation mode and the internal air circulation mode are thus selected (the operating member 20 is in the left position), the above-mentioned operation is performed. Similarly, the bending portion 10b of the locking member 10 allows the actuating member 2 to
0 is moved to the right position, and in response to this movement, the right side of the actuating member 20 is brought into contact with the bent portion 1 of the locking member 11.
1b to the right to disengage the bent portion 11b from the cam protrusion 13. Then, holding the second operator 4 in the push-in position is a normal release operation (Fig. 3b) regardless of the operation of the second operator 4.
Therefore, the operation of the second switch mechanism 17 is automatically canceled and the outside air intake mode is selected.
Further, the first switch mechanism 16 is connected to the first operator 3.
In response to the pressing operation, the defrost mode is finally held in the activated state and the defrost mode is selected. In other words, when the ventilation mode is switched to the defrost mode with the inside air circulation mode selected, the switch from the inside air circulation mode to the outside air intake mode is automatically performed by simply selecting the defrost mode. This allows the defrosting operation to be carried out using relatively dry air outside the vehicle.

Incidentally, the present invention is not limited to the first embodiment described above; for example, as in the second embodiment of the present invention shown in FIG.
0a, 11a may be fitted into protrusions 1b, 1b protruding from the lower part of the case 1 in FIG. good. However, in this case, the contact element 22
It is necessary to define the shape so that it does not interfere with the operation of the lock member 11. In addition, as in the third embodiment of the present invention shown in FIGS. 6 and 7, the first operator 3
In addition to providing two pairs of second operators 4, two pairs of first switch mechanisms 16, second switch mechanisms 17, etc. may also be provided. In this case, the actuating member 23 whose planar shape and side shape are shown in FIGS. 6 and 7, respectively, is used. Furthermore, the present invention may be configured as a fourth embodiment shown in FIGS. 8 to 10, and the specific configuration of this fourth embodiment will be described below.

That is, the difference between this fourth embodiment and the first embodiment is that the operator 22 of the second operator 4 is removed, and as a result, the slope 20a of the actuating member 20 is no longer necessary. In addition, the shape of the heart-shaped cam groove 15 has been simplified as shown in FIGS. 9b and 10b. In this case, the shape of the heart-shaped cam groove 15 is the shape of the bent portion 11b of the locking member 11.
is in elastic contact with the cam surface "'" of the heart-shaped cam groove 15 (particularly with the bent portion 11b in its original position) and in elastic contact with the cam surface "'" of the heart-shaped cam groove 15 In each case (especially when the bent portion 11b is engaged with the cam protrusion 13),
The bent portion 11b is set so as to protrude toward the front in FIG. 8 and come into contact with the right end surface of the actuating member 20. The actuating member 20 then locks the locking member 11.
The right side surface is biased leftward by the bent portion 11b of , and is always located on the left side. According to the above configuration, when the actuating member 20 is in the left position as shown by the solid line in FIG.
When a pressing operation is performed in the direction, the left end surface of the actuating member 20 is moved to the right at the bent portion 10b of the locking member 10, which moves the cam surface ``'' in the direction of the arrow C in response to the pressing operation, as in the first embodiment. As a result, the actuating member 20 is displaced against the spring force of the locking member 11 to the right position shown by the two-dot chain line in FIG.
Therefore, when the first operator 3 is pressed in the direction of the arrow Y while the second operator 4 is held in the push-in position, the second operator 4 is pressed in the same manner as in the first embodiment. The hold in the pressed position is forcibly released without going through a regular release operation. Thereafter, the actuating member 20 is returned to the left position by the bent portion 11b of the locking member 11 as described above.
Incidentally, when the push buttons 6 and 7 are simultaneously pressed in the direction of arrow Y from the state shown in FIG.
is pressed and displaced to the right, but at the same time the lock member 1
Since the bent portion 11b of 1 also moves to the right with the pressing operation of the operator 4, there is no problem in the operation of each operator 3, 4 and also in the operation of the first and second holding means 8 and 9. .

On the other hand, the characteristic configuration of the fourth embodiment (that is, the difference from the first embodiment described above) may be applied to the second embodiment, and an example thereof is shown in FIG. This is shown as a fifth embodiment. In addition, as shown in FIG. 12 showing a sixth embodiment of the present invention, the cam protrusion 12 and the heart-shaped cam groove 14 in the fifth embodiment are
cam protrusion 13 and heart-shaped cam groove 15 respectively.
A cam protrusion 24 and a heart-shaped cam groove 25 having the same shape as
It is also possible to have a configuration in which

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, valve mechanisms may be applied as the first and second switching mechanisms, etc., as appropriate without departing from the gist thereof. It can be modified and implemented.

As explained above, the present invention provides an operating device for a switching mechanism configured to individually operate at least a pair of first and second switching mechanisms by operating elements, in which a second switching mechanism is operated by a second operating element. When the first operator is operated while the switching mechanism is operated, the operation of the second switching mechanism can be automatically canceled, and the first and second switching mechanisms can also be operated individually. This has the excellent effect of simplifying the operation and diversifying the operation modes. In addition, as mentioned above, the function of automatically canceling the operation of the second switching mechanism is
This is achieved by swinging the second lock member by the actuating member that is displaced in response to the pressing operation of the first operating element, but the actuating member does not lock the first lock that the first switching mechanism originally has. Since it is configured to be displaced by pressure by a member, there is no need to separately provide a special member for the pressure displacement.
A practical effect of simplifying the overall configuration can also be obtained.
