BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to multidirectional input devices with which multidirectional
input operation can be performed.
2. Description of the Related Art
[0002] Hitherto, devices with which multidirectional input operation can be performed, such
as a vehicle power seat switch, have been known. For example, a switch device disclosed
in Japanese Unexamined Patent Application Publication No.
2004-288393 is configured such that a seat portion of a vehicle seat can be moved in the front-rear
direction by slidingly operating a first operation knob in the front-rear direction,
and a seat back of the vehicle seat can be inclined in the front-rear direction by
rotationally operating a second operation knob.
SUMMARY OF THE INVENTION
[0003] However, in a conventional switch device such as that described above, an operation
knob for sliding operation and an operation knob for rotational operation are separately
provided, and therefore the operation is complicated. In addition, such a plurality
of operation knobs increase the size of the whole device, and also increase the cost.
Thus, conventional multidirectional input devices can have various disadvantages due
to the fact that a knob for sliding operation and a knob for rotational operation
are separately provided.
[0004] The present invention is made in view of such circumstances, and provides a multidirectional
input device such that input by sliding operation and rotational operation can be
performed with a single knob.
[0005] In an aspect of the present invention, a multidirectional input device includes a
knob that receives sliding operation in a first direction and a second direction perpendicular
to each other and rotational operation about an axis of rotation perpendicular to
the first direction and the second direction, a first slider that operates integrally
with the knob, a first switch mechanism having a plurality of contacts that are each
turned on or off in response to the displacement of the first slider in the first
direction or the second direction, a second slider that operates by engaging with
the first slider rotating in response to the rotational operation and the first slider
moving in the first direction in response to the sliding operation, but does not engage
with the first slider moving in the second direction in response to the sliding operation,
and a second switch mechanism having at least one contact that is turned on or off
in response to the displacement of the second slider operating by engaging with the
first slider rotating, and keeps being turned on or off despite the displacement of
the second slider operating by engaging with the first slider moving in the first
direction.
[0006] With this configuration, since the first switch mechanism that is turned on or off
in response to the sliding operation of the knob, and the second switch mechanism
that is turned on or off in response to the rotational operation of the knob are provided,
input by sliding operation and rotational operation can be performed with a single
knob. As a result, compared to a configuration having a plurality of knobs, an increase
in the size of the whole device and an increase in cost are suppressed.
[0007] It is preferable that the first slider have a shaft portion connected to the knob
and extending along the axis of rotation, and an engaging portion with which the shaft
portion is provided, and the second slider have an engaged portion that engages with
the engaging portion of the first slider rotating in response to the rotational operation
and the engaging portion of the first slider moving in the first direction in response
to the sliding operation.
[0008] With this configuration, the first slider and the second slider can be engaged with
each other by means of the engaging portion of the first slider and the engaged portion
of the second slider.
[0009] It is preferable that the engaging portion of the first slider have an engaging surface
extending parallel to the second direction, and the engaged portion of the second
slider face the engaging surface of the engaging portion.
[0010] With this configuration, since the engaging surface of the engaging portion of the
first slider extends parallel to the second direction, the engaging portion of the
first slider can be prevented from engaging with the engaged portion of the second
slider when the first slider moves in the second direction in response to sliding
operation.
[0011] It is preferable that the engaged portion of the second slider be a rib having an
engaged surface extending parallel to the second direction.
[0012] With this configuration, when the first slider moves in the first direction, the
engaged surface extending parallel to the second direction and the engaging surface
extending parallel to the second direction can be reliably engaged with each other,
and, when the first slider moves in the second direction, the engaged surface and
the engaging surface can be prevented from engaging with each other.
[0013] It is preferable that the knob be connected to one end of the shaft portion, the
engaging portion be provided at the other end of the shaft portion, and the second
slider have a hole portion through which the shaft portion is passed between the knob
and the engaging portion.
[0014] With this configuration, the first slider and the second slider can be disposed such
that the shaft portion of the first slider is passed through the hole portion of the
second slider.
[0015] It is preferable that the first switch mechanism have a first actuator that rocks
in the first direction and the second direction in response to the displacement of
the first slider in the first direction and the second direction, and each of the
plurality of contacts of the first switch mechanism be turned on or off in response
to the rocking of the first actuator.
[0016] With this configuration, the first switch mechanism can be formed using the first
actuator that rocks in response to the sliding operation of the knob.
[0017] It is preferable that the first slider be connected to the first actuator so as to
be rotatable relative to the first actuator in response to the rotational operation.
[0018] With this configuration, the first actuator can be prevented from operating when
the knob is rotated.
[0019] It is preferable that the first switch mechanism have a plurality of pressing members
that each press at least one of the plurality of contacts of the first switch mechanism
in response to the rocking of the first actuator, and each of the plurality of contacts
of the first switch mechanism be turned on or off in response to the pressing by the
pressing members.
[0020] With this configuration, the first switch mechanism can be formed using the pressing
member that presses the contact in response to the rocking of the first actuator.
[0021] It is preferable that the second switch mechanism have a second actuator that rocks
in response to the displacement of the second slider operating by engaging with the
first slider rotating, but does not rock in response to the displacement of the second
slider operating by engaging with the first slider moving in the first direction,
and the at least one contact of the second switch mechanism be turned on or off in
response to the rocking of the second actuator.
[0022] With this configuration, the second switch mechanism can be formed using the second
actuator that rocks in response to the rotational operation of the knob but does not
rock in response to sliding operation.
[0023] It is preferable that the second slider have a protruding portion that faces the
second actuator and protrudes toward the second actuator, and the second actuator
rock by being pressed by the protruding portion of the second slider operating by
engaging with the first slider rotating.
[0024] With this configuration, the second actuator can be rocked by the protruding portion
of the second slider.
[0025] It is preferable that the second slider rotate by engaging with the first slider
rotating, and move in the first direction by engaging with the first slider moving
in the first direction, and the second actuator rock in the second direction by being
pressed by the protruding portion of the second slider rotating, but does not pressed
by the protruding portion of the second slider moving in the first direction.
[0026] With this configuration, the second actuator can be rocked by being pressed by the
protruding portion when the second slider rotates, and can be prevented from being
pressed by the protruding portion when the second slider moves in the first direction.
[0027] It is preferable that the second actuator have, on its surface facing the protruding
portion, an inclined portion that inclines in the second direction, and the inclined
portion be pressed by the protruding portion of the second slider rotating and rock
in the second direction.
[0028] With this configuration, the protruding portion of the second slider can press the
inclined portion of the second actuator in response to the displacement in the second
direction of the second slider rotating.
[0029] It is preferable that the second switch mechanism have at least one pressing member
that presses the at least one contact of the second switch mechanism in response to
the rocking of the second actuator, and the at least one contact of the second switch
mechanism be turned on or off in response to the pressing by the pressing member.
[0030] With this configuration, the second switch mechanism can be formed using the pressing
member that presses the contact in response to the rocking of the second actuator.
[0031] It is preferable that the first switch mechanism and the second switch mechanism
be disposed side by side in the first direction, the first slider be located on the
knob side of the first switch mechanism, and the second slider be located on the knob
side of the first switch mechanism and the second switch mechanism, and have a shape
having its longitudinal direction in the first direction.
[0032] With this configuration, the first switch mechanism and the second switch mechanism
can be disposed side by side in the first direction.
[0033] It is preferable that the multidirectional input device include a panel located between
the knob and the first slider, and the range of movement of the knob be restricted
by a restricted member provided on the panel side of the knob and a restricting member
provided on the knob side of the panel.
[0034] With this configuration, the range of movement of the knob can be restricted.
[0035] It is preferable that when the knob is displaced in the first direction in response
to the sliding operation in the first direction, at least part of the restricting
member of the panel is located on both sides in the second direction.
[0036] With this configuration, since, when the knob is displaced in the first direction,
the movement in the second direction is restricted by the restricting member of the
panel located on both sides in the second direction, sliding operation and rotational
operation in the second direction when sliding operation in the first direction is
performed can be limited.
[0037] The present invention can provide a multidirectional input device such that input
by sliding operation and rotational operation can be performed with a single knob.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0039] A multidirectional input device according to an embodiment of the present invention
will be described below. Fig. 1 is an exploded perspective view of the multidirectional
input device 1 according to this embodiment. As shown in Fig. 1, the multidirectional
input device 1 includes a knob 10, a panel 12, a second slider 14, a first slider
16, a case 18, a first actuator 20, a second actuator 22, six pressing members 24,
an elastic member 26, and a circuit board 28. The multidirectional input device 1
functions as an input device that receives multidirectional input performed by sliding
and rotating the knob 10. The multidirectional input device 1 is used, for example,
as a vehicle power seat switch.
[0040] "X (X1 and X2)," "Y (Y1 and Y2)," and "Z (Z1 and Z2)" in Fig. 1 and subsequent figures
denote three directions perpendicular to each other. The X direction corresponds to
a second direction of the present invention, and the Y direction corresponds to a
first direction of the present invention.
[0041] Although, in Fig. 1, the panel 12 is depicted as a substantially rectangular member
having its longitudinal direction in the Y direction, the shape of the panel 12 is
appropriately changed according to the type or the like of product on which the multidirectional
input device 1 is mounted, and is not limited to the shape shown in Fig. 1.
[0042] Fig. 2 is an external view of a main part of the multidirectional input device 1,
Fig. 3 is an external view of the main part with the case 18 omitted, and Fig. 4 is
an external view of the main part with the case 18, the first slider 16, and the second
slider 14 omitted. As shown in Fig. 2 to Fig. 4, in the multidirectional input device
1, the first slider 16 and the second slider 14 are disposed on the Z2 direction side
of the case 18. At least part of a first switch mechanism 30 and a second switch mechanism
32 that include the first actuator 20, the second actuator 22, the pressing members
24, the elastic member 26 (dome portions 261), and the circuit board 28 (contacts
281) is housed in the case 18.
[0043] Fig. 5 is a perspective view of the second slider 14 as viewed from the opposite
direction as Fig. 2. As shown in Fig. 5, the second slider 14 has an annular portion
145 and an extending portion 146, and has a shape substantially like a bottle cap
opener as a whole. The annular portion 145 has a substantially annular shape and has
therein a hole portion 141 that is a through-hole. The extending portion 146 has a
substantially plate-like shape and extends from the annular portion 145 in the Y1
direction. The hole portion 141 has a substantially elliptical shape such that the
diameter in the X direction is larger than the diameter in the Y direction. The middle
part in the X direction of the hole portion 141 slightly bulges in the Y direction.
The second slider 14 is formed, for example, of insulating synthetic resin.
[0044] As shown in Fig. 5, a pair of ribs 142 and 143 and a protruding portion 144 that
are engaged portions are provided on the back surface (the surface facing the case
18) of the second slider 14. The rib 142 is located on the Y2 direction side of the
annular portion 145 and extends parallel to the X direction. The rib 143 is located
on the Y1 direction side of the annular portion 145 (near the boundary between the
annular portion 145 and the extending portion 146), and, as with the rib 142, it extends
parallel to the X direction. The inner surfaces of the ribs 142 and 143 (the Y1 direction
side surface of the rib 142 and the Y2 direction side surface of the rib 143) function
as engaged surfaces 1421 and 1431 for engaging with the first slider 16.
[0045] As shown in Fig. 5, the protruding portion 144 is located on the Y1 direction of
the extending portion 146 and protrudes in a direction substantially perpendicular
to the extending portion 146 (Z1 direction). The protruding portion 144 has a substantially
semicircular contour as viewed from the Y direction.
[0046] Fig. 6 is a perspective view of the first slider 16. As shown in Fig. 6, the first
slider 16 has a substantially cylindrical shaft portion 161, and an engaging portion
162 that is provided at the Z1 direction side (case 18 side) end of the shaft portion
161 and has a substantially rectangular frame shape substantially perpendicular to
the shaft portion 161. The first slider 16 is formed, for example, of insulating synthetic
resin.
[0047] As shown in Fig. 6, the shaft portion 161 is provided, at both ends in the X direction,
with a pair of ribs 1611 and 1612 extending in the Z direction. The ribs 1611 and
1612 extend from the base part of the shaft portion 161 (the part connected to the
engaging portion 162) to a position of about three-quarters of the full length in
the Z direction.
[0048] As shown in Fig. 6, the engaging portion 162 has engaging surfaces 1621 and 1622
on both sides in the Y direction. The engaging surfaces 1621 and 1622 each extend
in the X direction.
[0049] As shown in Fig. 2 and Fig. 3, the first slider 16 is disposed such that the engaging
portion 162 is located on the Z1 direction side of the annular portion 145 of the
second slider 14, and the shaft portion 161 protrudes in the Z2 direction through
the hole portion 141 in the annular portion 145. The engaging surfaces 1621 and 1622
of the engaging portion 162 of the first slider 16 face the engaged surface 1421 of
the rib 142 and the engaged surface 1431 of the rib 143 of the second slider 14 with
a slight space therebetween.
[0050] Fig. 7 is a perspective view of the case 18, and Fig. 8 is a perspective view of
the case 18 as viewed from the opposite direction as Fig. 7. As shown in Fig. 7 and
Fig. 8, the case 18 has a first case 181 and a second case 182 each having a substantially
box shape. The first case 181 and the second case 182 are disposed side by side in
the Y direction. The case 18 is formed, for example, of insulating synthetic resin.
[0051] As shown in Fig. 7 and Fig. 8, the first case 181 is open in the Z1 direction, and
a top plate portion 1811 on the Z2 direction side is provided with a cross-shaped
slit 1813 extending in the X direction and the Y direction. A shown in Fig. 8, the
first case 181 has a housing portion 1815 that is formed by four wall portions 1816
extending in the Z1 direction at the four corners of the intersection of the cross
shape of the slit 1813. The housing portion 1815 houses a main body portion 202 of
the first actuator 20 described later such that the first actuator 20 is rockable.
[0052] As shown in Fig. 7 and Fig. 8, the second case 182 is open in the Z1 direction, and
a top plate portion 1821 on the Z2 direction side is provided with a slit 1823 extending
in the X direction. As shown in Fig. 8, the second case 182 is provided with a pair
of wall portions 1824 extending in the Z1 direction on both side edges in the Y direction
of the slit 1823. The substantially middle part in the X direction of each of the
wall portions 1824 is recessed in the Z2 direction, and a housing portion 1826 is
thereby formed. The housing portion 1826 houses a shaft portion 221 of the second
actuator 22 described later such that the second actuator 22 is rockable in the X
direction. As is clear, for example, from Fig. 2 and Fig. 3, the slit 1823 faces the
protruding portion 144 of the second slider 14, on the Z2 direction side thereof.
[0053] Fig. 9 is a perspective view of the first actuator 20, and Fig. 10 is a perspective
view of the first actuator 20 as viewed from the opposite direction as Fig. 9. As
shown in Fig. 9 and Fig. 10, the first actuator 20 has a substantially spherical main
body portion 202, a substantially cylindrical arm portion 201 extending in the Z2
direction from the main body portion 202, and four leg portions 203 extending in the
X1, X2, Y1, and Y2 directions from the main body portion 202. The first actuator 20
is formed, for example, of insulating synthetic resin.
[0054] As is clear, for example, from Fig. 2 to Fig. 4, the first actuator 20 is housed
in the first case 181 in the X direction and the Y direction, and the arm portion
201 protrudes in the Z2 direction through the slit 1813 of the first case 181. The
end in the Z2 direction of the arm portion 201 is housed in the end in the Z1 direction
of the hollow shaft portion 161 of the first slider 16. As described above, the main
body portion 202 of the first actuator 20 is housed in the housing portion 1815 of
the first case 181 such that the first actuator 20 is rockable. As a result, the first
actuator 20 rocks (inclines) in the X direction in response to the movement of the
first slider 16 in the X direction, and rocks in the Y direction in response to the
movement of the first slider 16 in the Y direction.
[0055] Fig. 11 is a perspective view of the second actuator 22. As shown in Fig. 11, the
second actuator 22 has a substantially cylindrical shaft portion 221 having an axis
extending in the Y direction, and a pair of wing portions 222 and 223 extending in
the X1 direction and the X2 direction from the shaft portion 221. The second actuator
22 is formed, for example, of insulating synthetic resin.
[0056] As shown in Fig. 11, the wing portions 222 and 223 have a substantially inverted
V shape as viewed from the Y direction. The Z2 direction side surfaces of the wing
portions 222 and 223 incline in the Z2 direction from their base parts (parts connected
to the shaft portion 221) toward their substantially middle parts in the X1 direction
and the X2 direction, and incline in the Z1 direction from their middle parts toward
their outer ends. That is, the wing portions 222 and 223 of the second actuator 22
have inclined portions 2221 and 2231 corresponding to parts from the base parts to
the substantially middle parts in the X direction and inclining in the Z2 direction,
and inclined portions 2222 and 2232 corresponding to parts from the substantially
middle parts in the X direction to the outer ends and inclining in the Z1 direction.
[0057] As shown in Fig. 11, the Z2 direction side surface of the shaft portion 221 is recessed
in the Z1 direction from the inclined portion 2221 of the wing portion 222 and the
inclined portion 2231 of the wing portion 223 on both sides in the X direction, and
as a result, a stepped portion 2211 is formed.
[0058] As shown in Fig. 3, the stepped portion 2211 of the second actuator 22 faces the
distal end of the protruding portion 144 of the second slider 14 with a slight space
therebetween. As is clear, for example, from Fig. 2 to Fig. 4, the second actuator
22 is housed in the second case 182 in the X direction and the Y direction, and parts
(ends in the Z direction) of the wing portions 222 and 223 protrude in the Z2 direction
through the slit 1823 of the second case 182. As described above, the shaft portion
221 of the second actuator 22 is housed in the housing portion 1826 of the second
case 182 such that the second actuator 22 is rockable in the X direction. As a result,
when the second slider 14 moves in the X direction, the inclined portion 2221 or the
inclined portion 2231 is pressed by the protruding portion 144 and the second actuator
22 rocks (inclines) in the X direction. On the other hand, when the second slider
14 moves in the Y direction, the protruding portion 144 moves in the Y direction with
its distal end facing the stepped portion 2211 with a slight space therebetween. That
is, the second actuator 22 does not rock when the second slider 14 moves in the Y
direction.
[0059] As shown in Fig. 4, one of the pressing members 24 is disposed on the Z1 direction
side of each of the four leg portions 203 of the first actuator 20 and the pair of
wing portions 222 and 223 of the second actuator 22. The pressing members 24 have
a substantially bench-like shape having a pair of legs extending in the Z2 direction.
The pressing members 24 are disposed such that their longitudinal directions are substantially
perpendicular to the longitudinal directions of the leg portions 203 and the wing
portions 222 and 223.
[0060] As shown in Fig. 3 and Fig. 4, two of the dome portions 261 of the elastic member
26 are disposed on the Z1 direction side of each pressing member 24 such that they
are arranged side by side in the longitudinal direction of the pressing member 24.
The dome portions 261 protrude in the Z2 direction. The elastic member 26 is formed
of various materials having elasticity.
[0061] As shown in Fig. 1, one of the contacts 281 of the circuit board 28 is located on
the Z1 direction side of each dome portion 261 of the elastic member 26. Therefore,
when any one of the leg portions 203 is inclined in the Z1 direction with the rocking
of the first actuator 20, two of the dome portions 261 are pressed via a corresponding
one of the pressing members 24, and as a result, corresponding two of the contacts
281 are turned on or off. Thus, the first actuator 20, the pressing members 24, the
elastic member 26, and the circuit board 28 form the first switch mechanism 30 of
the present invention.
[0062] When any one of the wing portions 222 and 223 is inclined in the Z1 direction with
the rocking of the second actuator 22, two of the dome portions 261 are pressed via
a corresponding one of the pressing members 24, and as a result, corresponding two
of the contacts 281 are turned on or off. Thus, the second actuator 22, the pressing
members 24, the elastic member 26, and the circuit board 28 form the second switch
mechanism 32 of the present invention.
[0063] As shown in Fig. 1, the knob 10 has a substantially box shape. The knob 10 is open
in the Z1 direction. Fig. 12 is a back view of the knob 10 viewed from the Z2 direction.
A cylindrical portion 104 having a substantially cylindrical shape and extending in
the Z1 direction is provided substantially in the center of the Z1 direction side
surface (back surface) of the top plate portion 105 of the knob 10. A pair of grooves
1041 extending in the Z direction are formed on both sides in the X direction of the
cylindrical portion 104. The shaft portion 161 of the first slider 16 is inserted
into the cylindrical portion 104. At this time, the ribs 1611 and 1612 of the shaft
portion 161 are fitted in the grooves 1041 of the cylindrical portion 104, and the
first slider 16 is unrotatably fixed to the knob 10.
[0064] As shown in Fig. 12, three wall-like restricted members 101, 102, and 103 are formed
on the back surface of the top plate portion 105. On the back surface of the top plate
portion 105, the restricted member 101 is located on the Y1 direction side of the
end in the X1 direction, the restricted member 102 is located at the end in the Y2
direction along the inner wall of the knob 10, and the restricted member 103 is located
on the Y1 direction side of the end in the X2 direction. A region 1061 is formed by
the restricted member 101 and the restricted member 102, and a region 1062 is formed
by the restricted member 102 and the restricted member 103.
[0065] Fig. 13 is an enlarged perspective view showing part of the panel 12. As shown in
Fig. 13, the panel 12 has a through-hole 121, and restricting members 1221 and 1222
are provided on both sides in the X direction of the through-hole 121. The restricting
members 1221 and 1222 are members protruding in the Z2 direction, and have a substantially
T-shaped contour as viewed from the Z direction. The tips of the T-shaped restricting
members 1221 and 1222 face outward in the X direction. Although not shown, the shaft
portion 161 of the first slider 16 is unrotatably fixed to the cylindrical portion
104 of the knob 10 in the through-hole 121 of the panel 12.
[0066] With reference to Fig. 14 to Fig. 17, the operation will be described in which the
range of movement of the knob 10 is restricted by the restricted members 101, 102,
and 103 on the back surface of the knob 10 and the restricting members 1221 and 1222
of the panel 12.
[0067] Fig. 14 schematically shows the back surface of the knob 10 when the knob 10 is in
its home position. As shown in Fig. 14, when the knob 10 is in its home position,
the restricting members 1221 and 1222 of the panel 12 are located substantially in
the centers of the regions 1061 and 1062.
[0068] Fig. 15 schematically shows the back surface of the knob 10 when the knob 10 is slid
in the X direction. As shown in Fig. 15, when the knob 10 is slid in the X1 direction,
the restricting members 1221 and 1222 relatively move in the X2 direction (restricting
members 1221A and 1222A). At this time, the end in the X2 direction of the substantially
T-shaped restricting member 1222A is fitted in a U-shaped region formed by the restricted
members 102 and 103, and as a result, the movement of the knob 10 in the X1 direction
is limited. Parts of the restricted members 101 and 102 are located on both sides
in the Y direction of the restricting member 1221A. Therefore, in this state, the
knob 10 cannot be slid in the Y direction, and cannot be rotated.
[0069] Similarly, as shown in Fig. 15, when the knob 10 is slid in the X2 direction, the
restricting members 1221 and 1222 relatively move in the X1 direction (restricting
members 1221B and 1222B). At this time, the end in the X1 direction of the substantially
T-shaped restricting member 1221B is fitted in a U-shaped region formed by the restricted
members 101 and 102, and as a result, the movement of the knob 10 in the X2 direction
is limited. Parts of the restricted members 101 and 103 are located on both sides
in the Y direction of the restricting member 1222B. Therefore, in this state, the
knob 10 cannot be slid in the Y direction, and cannot be rotated.
[0070] Fig. 16 schematically shows the back surface of the knob 10 when the knob 10 is slid
in the Y direction. As shown in Fig. 16, when the knob 10 is slid in the Y1 direction,
the restricting members 1221 and 1222 relatively move in the Y2 direction (restricting
members 1221C and 1222C). At this time, the ends in the Y2 direction of the restricting
members 1221C and 1222C come into contact with the restricted member 102. As a result,
the movement of the knob 10 in the Y1 direction is limited.
[0071] Similarly, as shown in Fig. 16, when the knob 10 is slid in the Y2 direction, the
restricting members 1221 and 1222 relatively move in the Y1 direction (restricting
members 1221D and 1222D). At this time, the ends in the Y1 direction of the restricting
members 1221D and 1222D come into contact with the restricted members 101 and 103.
As a result, the movement of the knob 10 in the Y2 direction is limited.
[0072] Fig. 17 schematically shows the back surface of the knob 10 when the knob 10 is rotated.
As shown in Fig. 17, when the knob 10 is rotated in the R1 direction, the restricting
member 1221 relatively moves in the Y2 direction (1221E), and the restricting member
1222 relatively moves in the Y1 direction (1222E). At this time, the restricting member
1221E comes into contact with the restricted member 102, and the restricting member
1222E comes into contact with the restricted member 103. As a result, the rotation
of the knob 10 in the R1 direction is limited.
[0073] Similarly, as shown in Fig. 17, when the knob 10 is rotated in the R2 direction,
the restricting member 1221 relatively moves in the Y1 direction (1221F), and the
restricting member 1222 relatively moves in the Y2 direction (1222F). At this time,
the restricting member 1221F comes into contact with the restricted member 101, and
the restricting member 1222F comes into contact with the restricted member 102. As
a result, the rotation of the knob 10 in the R2 direction is limited.
[0074] In the thus configured multidirectional input device 1, the knob 10 receives sliding
operation and rotational operation in the X direction and the Y direction within the
above-described range of movement. When the knob 10 is slid in the X direction, the
first slider 16, which operates integrally with the knob 10, also moves in the X direction.
At this time, since the engaged surfaces 1421 and 1431 of the second slider 14, and
the engaging surfaces 1621 and 1622 of the first slider 16 are both parallel to the
X direction, the second slider 14 does not engage with the first slider 16. When the
first slider 16 moves in the X direction, the end in the Z2 direction of the arm portion
201 of the first actuator 20 moves in the X direction, and the first actuator 20 rocks
and inclines in the X1 direction or the X2 direction. When the first actuator 20 inclines,
corresponding contacts 281 are pressed via corresponding pressing member 24 and elastic
member 26 (dome portions 261) and turned on or off.
[0075] When the knob 10 is slid in the Y direction, the first slider 16, which operates
integrally with the knob 10, also moves in the Y direction. At this time, the engaging
surfaces 1621 and 1622 of the engaging portion 162 of the first slider 16 engage with
the engaged surfaces 1421 and 1431 of the ribs 142 and 143 of the second slider 14.
As a result, the second slider 14 also moves in the Y direction.
[0076] When the first slider 16 moves in the Y direction, the end in the Z2 direction of
the arm portion 201 of the first actuator 20 moves in the Y direction, and the first
actuator 20 rocks and inclines in the Y1 direction or the Y2 direction. When the first
actuator 20 inclines, corresponding contacts 281 are pressed via corresponding pressing
member 24 and elastic member 26 (dome portions 261) and turned on or off. On the other
hand, when the second slider 14 moves in the Y direction, the protruding portion 144
of the second slider 14 moves in the Y direction with its distal end facing the stepped
portion 2211 with a slight space therebetween, and therefore the second actuator 22
does not operate.
[0077] When the knob 10 is rotated, the first slider 16, which operates integrally with
the knob 10, also rotates about the shaft portion 161. At this time, the engaging
surfaces 1621 and 1622 of the engaging portion 162 of the first slider 16 engage with
the engaged surfaces 1421 and 1431 of the ribs 142 and 143 of the second slider 14.
As a result, the second slider 14 also rotates about the shaft portion 161.
[0078] When the second slider 14 rotates, the protruding portion 144 moves in the X direction
and presses the inclined portion 2221 or 2231, and the second actuator 22 rocks and
inclines in the X1 direction or the X2 direction. When the second actuator 22 inclines,
corresponding contacts 281 are pressed via corresponding pressing member 24 and elastic
member 26 (dome portions 261) and turned on or off. On the other hand, when the first
slider 16 rotates, the first actuator 20 does not operate because the first actuator
20 is rotatably connected to the first slider 16.
[0079] The first actuator 20 and the second actuator 22 that are inclined in response to
the operation of the knob 10 are returned to their home positions by the elastic force
in the Z2 direction of the dome portions 261 of the elastic member 26 when the knob
10 is released from the operation.
[0080] The present invention is not limited to the above-described embodiment. Namely, those
skilled in the art may make various modifications, combinations, sub-combinations,
and alterations to the elements of the above embodiment insofar as they are within
the technical scope of the present invention or within the scope of its equivalents.
[0081] For example, the shapes of the first slider 16 and the second slider 14 are illustrative,
and the first slider and the second slider can have various shapes.
[0082] The shapes of the first actuator 20 and the second actuator 22 are illustrative,
and the first actuator and the second actuator can have various shapes. The configurations
of the first switch mechanism and the second switch mechanism are not limited to those
described above, and the first switch mechanism and the second switch mechanism can
have various configurations. For example, moving contacts facing the contacts 281
may be provided on the Z1 direction side of the dome portions 261 so that when the
dome portions 261 are pressed, the contacts 281 come into contact with the moving
contacts.
[0083] The present invention can be applied, for example, to a vehicle power seat switch.
