[0047] The display apparatus 1 according to the embodiment of the
present disclosure may include a base 10, a stand 20 and a head
30.
[0048] The base 10 may support the display apparatus 1 against a
floor.
[0049] The stand 20 may vertically extend upward from the base 10.
The stand 20 may connect the base 10 with the head 30. The stand 20
may have, but is not limited to, a vertical bar shape.
[0050] More specifically, the lower end of the stand 20 may be
connected to the circumference of the base 10. A stand connector 19
protruding outward may be formed on the circumference of the base
10, and the lower end of the stand 20 may be connected to the stand
connector 19.
[0051] The head 30 may be spaced apart upward from the base 10. A
display 31 may be provided on the front surface of the head 30. An
image or video may be displayed on the display 31. In addition, the
display 31 may include a touchscreen.
[0052] Circumferences 32 and 33 of the head 30 may include a pair
of long sides 32 and a pair of short sides 33. The longitudinal
direction of the long side 32 and the longitudinal direction of the
short side 33 may be perpendicular to each other. The length L1 of
the long side 32 may be greater than the length L2 of the short
side 33.
[0053] The head 30 may be pivoted between a landscape mode in which
the long sides 32 are horizontal and the short sides 33 are
vertical (see FIG. 1) and a portrait mode in which the long sides
32 are vertical and the short sides 33 are horizontal (see FIG.
2).
[0054] The head 30 may be located on the same side as the base 10
with respect to the stand 20. That is, the head 30 may overlap the
base 10 in the vertical direction. Accordingly, since the center of
gravity of the display apparatus 1 does not deviate from the upper
side of the base 10, the display apparatus 1 may be stably
supported without being overturned.
[0055] The left-and-right length of the base 10 may be less than
the length L1 of the long side 32 of the head 30 and greater than
the length L2 of the short side 33. Accordingly, in the landscape
mode, the head 30 may laterally protrude from the base 10. The base
10 may laterally protrude from the head 30 in the portrait
mode.
[0056] The stand 20 may extend to be sufficiently long. The height
of the stand 20 may be greater than the length L1 of the long side
32 of the head 30. The height of the stand 20 may be greater than
the sum L1+L2 of the length L1 of the long side 32 of the head 30
and the length L2 of the short side.
[0057] The stand 20 may be connected to the circumferences 32 and
33 of the head 30. More specifically, the upper portion of the
stand 20 may be connected to the circumferences 32 and 33 of the
head 30.
[0058] Since the stand 20 is connected to the circumferences 32 and
33 rather than the rear surface of the head 30, the design of the
appearance of the display apparatus 1 may be improved, and the rear
surface of the head 30 may be used for another purpose. For
example, a mirror and a backlight may be provided on the rear
surface of the head 30.
[0059] The upper portion of the stand 20 may face the
circumferences 32 and 33 of the head 30 in the horizontal
direction. More specifically, in the landscape mode, the upper
portion of the stand 20 may face the short sides 33 of the head 30
in the horizontal direction. In the portrait mode, the upper
portion of the stand 20 may face the long sides 32 of the head 30
in the horizontal direction.
[0060] A penetration groove 34 may be formed in the circumferences
32 and 33 of the head 30. The penetration groove 34 may extend
along the circumferences 32 and 33 of the head 30. The head 30 may
be connected to the stand 20 through the penetration groove 34.
[0061] More specifically, a connecting bar 50 (see FIG. 6)
protruding toward the penetration groove 34 may be formed on the
stand 20. The connecting bar 50 may extend to the inside of the
head 30 through the penetration groove 34.
[0062] The penetration groove 34 may include a first groove 35
formed in the short side 33 and a second groove 36 formed in the
long side 32. The first groove 35 may extend along the short side
33 and the second groove 36 may extend along the long side 32. The
first groove 35 may be connected to the second groove 36. The first
groove 35 may be connected to the second groove 36 at a corner of
the circumferences 32 and 33.
[0063] The first groove 35 may be formed in any one of the pair of
short sides 33. The length of the first groove 35 may be less than
that of the short side 33 and may be greater to or equal to half
the length of the short side 33.
[0064] The second groove 36 may be formed in any one of the pair of
long sides 32. The length of the second groove 36 may be less than
that of the long side and may be greater to or equal to half the
length of the long side 32.
[0065] Accordingly, at the time of pivot of the head 30, the
connecting bar 50 (see FIG. 6) may be maintained in a state of
passing through the penetration groove 34. In the landscape mode,
the connecting bar 50 may extend to the inside of the head 30
through the first groove 35. In the portrait mode, the connecting
bar 50 may extend to the inside of the head 30 through the second
groove 36.
[0066] The stand 20 may include a cradle 24. The cradle 24 may be
horizontally disposed. A terminal such as a smartphone may be
mounted on the cradle 24. The display apparatus 1 may be configured
to perform charging of the terminal mounted on the cradle 24. In
addition, the display apparatus 1 may be configured to selectively
mirror the screen of the terminal mounted on the cradle 24 to the
display 31 of the head 30.
[0067] The cradle 24 may be located at a lower height than the head
30. More specifically, a vertical distance from the base 10 to the
cradle 24 may be less than a vertical distance from the base 10 to
the head 30.
[0068] In addition, the head 30 and the cradle 24 may located at
opposite sides of the stand 20. More specifically, the head 30 may
be located on one side of the stand 20 and the cradle 24 may be
located on the other side of the stand 20.
[0069] Meanwhile, as shown in FIG. 3, the head 30 may rotate about
a horizontal axis x1 with respect to the stand 20. The horizontal
axis x1 may correspond to the connecting bar 50 (see FIG. 6). The
connecting bar 50 may be rotatably connected to the stand 20, and
the head 30 may rotate along with the connecting bar 50. That is,
the head 30 may be tilted by a predetermined angle with respect to
the horizontal axis x1.
[0070] The head 30 may be tilted regardless of pivot of the head
30. That is, the head 30 may be tilted in the landscape mode and
may be tilted in the portrait mode.
[0071] In addition, the head may rotate (tilt) by up to 180
degrees. That is, the head 30 may rotate such that the display 31
faces backward and the rear surface of the head 30 faces
forward.
[0072] Accordingly, when the mirror and the backlight are provided
on the rear surface of the head 30, a user may utilize the display
apparatus as a standing mirror or a light.
[0073] In addition, as shown in FIG. 4, the head 30 may rotate
about a vertical axis x2 with respect to the base 10 along with the
stand 20. More specifically, the lower end of the stand 20 may be
rotatably connected to the stand connector 19 of the base 10.
Accordingly, the head 30 may be swiveled by a predetermined angle
with respect to the vertical axis x2.
[0074] The swivel motion of the head 30 may be performed regardless
of pivot and tilt of the head 30. That is, the head 30 may be
swiveled in the landscape mode, may be swiveled in the portrait
mode, and may be swiveled in a state of being tilted by a
predetermined angle.
[0075] FIG. 5 is a block diagram illustrating components of a

[0087] The microphone 122 processes an external acoustic signal
into electrical audio data. The processed audio data may be
variously used according to the function (or application program)
executed in the display apparatus 1. Meanwhile, the microphone 122
may include various noise removal algorithms to remove noise
generated in the process of receiving the external sound
signal.
[0088] The user input interface 123 receives information from the
user, and, when information is received through the user input
interface 123, the processor 180 may control operation of the
display apparatus 1 to correspond to the received information.
[0089] The user input unit 123 may include one or more of a
mechanical input element (for example, a mechanical key, a button
located on a front and/or rear surface or a side surface of the
terminal 1, a dome switch, a jog wheel, a jog switch, and the like)
or a touch input element. As one example, the touch input element
may be a virtual key, a soft key or a visual key, which is
displayed on a touchscreen through software processing, or a touch
key located on a location other than the touchscreen.
[0090] The learning processor 130 may train a model composed of an
artificial neural network using learning data. Here, the trained
artificial neural network may be referred to as a learning model.
The learning model may be used to infer a result value with respect
to new input data rather than learning data, and the inferred value
may be used as a basis for determining certain operation.
[0091] At this time, the learning processor 130 may include a
memory integrated with or implemented in the display apparatus 1.
Alternatively, the learning processor 130 may be implemented using
the memory 170, an external memory directly coupled to the display
apparatus 1 or a memory maintained in an external device.
[0092] The sensor 140 may acquire at least one of internal
information of the display apparatus 1, surrounding environment
information of the display apparatus 1 or user information using
various sensors.
[0093] At this time, the sensor included in the sensor 140 may
include a proximity sensor, an illumination sensor, an acceleration
sensor, a magnetic sensor, a gyroscope sensor, an inertia sensor,
an RGB sensor, a finger scan sensor, an ultrasonic sensor, an
optical sensor, a microphone, a Lidar, a radar, etc.
[0094] The output interface 150 may generate video, audio or
tactile output.
[0095] At this time, the output interface 150 may include a display

[0096] The output interface 150 may include at least one of a
display 31, a sound output unit 152, a haptic module 153 or an
optical output unit 154.
[0097] The display 31 displays (outputs) information processed in
the display apparatus 1. For example, the display 31 may display
execution screen information of an application program executed by
the display apparatus 1 or user interface (UI) and graphical user
interface (GUI) information according to the executed screen
information.
[0098] The display 31 may have an inter-layered structure or an
integrated structure with a touch sensor in order to realize a
touchscreen. The touchscreen may function as the user input unit
123 which provides an input interface between the display apparatus
1 and the user and provide an output interface between the terminal
1 and a user.
[0099] The sound output interface 152 may output audio data
received from the communication interface 110 or stored in the
memory 170 in a call signal reception mode, a call mode, a record
mode, a speech recognition mode, a broadcast reception mode, and
the like.
[0100] The sound output interface 152 may also include a receiver,
a speaker, a buzzer, or the like.
[0101] The haptic module 153 generates various tactile effects that
a user feels. A typical example of a tactile effect generated by
the haptic module 153 is vibration.
[0102] The optical output interface 154 may output a signal
indicating event generation using light of a light source of the
display apparatus 1. Examples of events generated in the display
apparatus 1 may include message reception, call signal reception, a
missed call, an alarm, a schedule notice, email reception,
information reception through an application, and the like.
[0103] The memory 170 may store data supporting various functions
of the display apparatus 1. For example, the memory 170 may store
input data, learning data, a learning model, a learning history,
etc. acquired in the input interface 120.
[0104] The processor 180 may determine at least one executable
operation of the display apparatus 1 based on information
determined or generated using a data analysis algorithm or a
machine learning algorithm. In addition, the processor 180 may
control the components of the display apparatus 1 to perform the
determined operation.
[0105] To this end, the processor 180 may request, search for,
receive or use the data of the learning processor 130 or the memory
170, and control the components of the display apparatus 1 to
perform predicted operation or operation determined to be
preferable among the at least one executable operation.
[0106] At this time, the processor 180 may generate a control
signal for controlling an external device and transmit the
generated control signal to the external device, when connection of
the external device is necessary to perform the determined
operation.
[0107] The processor 180 may acquire intention information with
respect to user input and determine a request of the user based on
the acquired intention information.
[0108] At this time, the processor 180 may acquire intention
information corresponding to user input using at least one of a
speech-to-text (STT) engine for converting voice input into a
character string or a natural language processing (NLP) engine for
acquiring intention information of a natural language.
[0109] At this time, at least one of the STT engine or the NLP
engine may be composed of an artificial neural network learned
according to a machine learning algorithm. In addition, at least
one of the STT engine or the NLP engine may be learned by the
learning processor 130, learned by an external learned server or
learned by distribution processing thereof.
[0110] The processor 180 may collect history information including
content on operation of the display apparatus 1 or the feedback of
the user for the operation, store the history information in the
memory 170 or the learning processor 130 or transmit the history
information to an external device such as an external server. The
collected history information may be used to update the learning
model.
[0111] The processor 180 may control at least some of the
components of the display apparatus 1, in order to drive an
application program stored in the memory 170. Further, the
processor 180 may operate by combining two or more of the
components included in the display apparatus 1, in order to drive
the application program.
[0112] FIG. 6 is a view showing the inside of a head according to
an embodiment of the present disclosure, FIG. 7 is an enlarged view
illustrating the periphery of a first guide pin according to an
embodiment of the present disclosure, FIG. 8 is an enlarged view
illustrating the periphery of a second guide pin according to an
embodiment of the present disclosure, and FIGS. 9 and 10 are views
illustrating pivot motion of a head according to an embodiment of
the present disclosure.
[0113] A mounting plate 37 may be disposed inside the head 30. A
plurality of electric components may be mounted on the mounting
plate 37. The electric components may include at least one of a
communication interface 110, an input interface 120, a sensor 140
or a processor 180. In addition, the sound output unit 152 may be
mounted on the mounting plate 37. The plurality of electric
components and the sound output unit 152 may be disposed not to
interfere with an inner plate 40 and the connecting bar 50.
[0114] The display apparatus may further include the inner plate 40
and the connecting bar 50.
[0115] The inner plate 40 may be disposed inside the head 30. The
inner plate 40 may be parallel with the display 31. The inner plate
40 may be fixed to the inside of the head 30. For example, the
inner plate 40 may be fixed to the mounting plate 37.
[0116] The inner plate 40 may be disposed at a position
corresponding to the penetration groove 34 formed in the
circumferences 31 and 32 of the head 30. For example, a first
groove 35 may be formed in a lower portion of the right side of the
head 30 and a second groove 36 may be formed in a right portion of
a lower side of the head 30, based on the direction shown in FIG.
6. In this case, the inner plate 40 may be disposed adjacent to the
lower right corner of the head 30.
[0117] A first guide groove 43 extending along a predetermined
curved trajectory may be formed in the inner plate 40. The first
guide groove 43 may be formed in the inner plate 40.
[0118] The first guide groove 43 may have both ends and may be
formed along a curved trajectory toward the circumferences 32 and
33 of the head 30. That is, the first guide groove 43 may be formed
along the curved trajectory toward the penetration groove 34.
[0119] The first guide groove 43 may guide the pivot route of the
head 30. More specifically, a first guide pin 54 inserted into the
first guide groove 43 may be protrude from the connecting bar 50.
Accordingly, at the pivot of the head 30, the inner plate 40 may be
slide with respect to the first guide pin 54 along the trajectory
of the first guide groove 43.
[0120] A distance between the first guide groove 43 and the
penetration groove 34 may vary in the longitudinal direction of the
first guide groove 43. More specifically, when the head 30 is in a
landscape mode, the horizontal distance between the first guide
groove 43 and a first groove 35 may decrease downward and then
increase. In addition, when the head 30 is in a landscape mode, the
vertical distance between the first guide groove 43 and a second
groove 36 may decrease and then increase toward the stand 20.
[0121] Meanwhile, the connecting bar 50 may connect the head 30
with the stand 20. More specifically, the connecting bar 50 may be
connected to the stand 20, and may be connected to the inner plate
40 by extending to the inside of the head 30 through the
penetration groove 34.
[0122] The connecting bar 50 may be horizontally maintained
regardless of tilt, pivot and swivel motion of the head 30.
[0123] The connecting bar 50 may overlap the inner plate 40 in the
front-and-rear direction. Hereinafter, the case where the
connecting bar 50 is arranged to pass the rear side of the inner
plate 40 will be described. However, the connecting bar 50 may be
arranged to pass the front side of the inner plate 40.
[0124] The first guide pin 54 inserted into the first guide groove
43 of the inner plate 40 may be formed in the connecting bar 50.
The first guide pin 54 may protrude forward from the connecting bar
50.
[0125] A second guide groove 58 may be formed in the connecting bar
50. The second guide groove 58 may extend in the longitudinal
direction of the connecting bar 50.
[0126] The first guide pin 54 may be located between the second
guide groove 58 and the penetration groove 34 of the head 30 in the
longitudinal direction of the connecting bar 50. That is, a
distance between the stand 20 and the first guide pin 54 in the
longitudinal direction of the connecting bar 50 may be less than a
distance between the stand 20 and the second guide groove 58.
[0127] The first guide pin 54 may be located between the second
guide groove 58 and a passage 52 (see FIG. 13) which will be
described below in the longitudinal direction of the connecting bar
50.
[0128] A second guide pin 46 inserted into the second guide groove
58 may protrude from the inner plate 40. The second guide pin 46
may protrude backward from the inner plate 40. However, the present
disclosure is not limited thereto and the second guide pin 46 may
be fixed to the inside of the head 30.
[0129] At the time of pivot of the head 30, the second guide pin 46
may slide along the second guide groove 58. The second guide pin 46
may slide between the inner and outer ends of the second guide
groove 58. The inner end may mean an end far from the stand 20
between both ends of the second guide groove 58 and the outer end
may mean an end close to the stand 20 between both ends of the
second guide groove 58.
[0130] That is, the first guide pin 54 of the connecting bar 50 may
be inserted into the first guide groove 43 of the inner plate 40,
and the second guide pin 46 of the inner plate 40 may be inserted
into the second guide groove 58 of the connecting bar 50. The first
guide groove 43 and the second guide groove 58 may extend along
different trajectories.
[0131] Therefore, the head 30, to which the inner plate 40 is
fixed, may be supported with respect to the connecting bar 50, and
the pivot motion of the head 30 may be guided.
[0132] As shown in FIG. 6, when the head 30 is in a landscape mode,
the first guide pin 54 may be located on one end of the first guide
groove 43, and the second guide pin 46 may be located between both
ends of the second guide groove 58.
[0133] As shown in FIG. 9, when the corners of the circumferences
32 and 33 of the head 30 face the stand 20 in a horizontal
direction, the first guide pin 54 may be located between both ends
of the first guide groove 43, and the second guide pin 46 may be
located on the inner end of the second guide groove 58.
[0134] As shown in FIG. 10, when the head 30 is in a portrait mode,
the first guide pin 54 may be located on the other end of the first
guide groove 46, and the second guide pin 46 may be located on the
outer end of the second guide groove 58.
[0135] FIG. 11 is a view showing the position of a first guide pin
in a first guide groove according to pivot of a head according to
an embodiment of the present disclosure.
[0136] One end of the first guide groove 43 and the second guide
pin 46 may be located on one line parallel with the long sides 32
of the head 30. More specifically, one end of the first guide
groove 43 and the second guide pin 46 may be located on one
horizontal line when the head 30 is in a landscape mode and may be
located on one vertical line when the head 30 is located on one
vertical line.
[0137] The other end of the first guide groove 43 and the second
guide pin 46 may be located on a line parallel with the short sides
of the head 30. More specifically, the other end of the first guide
groove 43 and the second guide pin 46 may be located on one
vertical line when the head 30 is in the landscape mode and may be
located on one horizontal line when the head 30 is in the portrait
mode.
[0138] Meanwhile, when the head 30 is in the landscape mode, the
first guide pin 59 may be located at a first point P1 of the first
guide groove 43. The first point P1 may be one end of the first
guide groove 43.
[0139] When the connecting bar 50 passes between the first groove
35 and the second groove 36 of the head 30, the first guide pin 59
may be located at a second point P2 of the first guide groove
43.
[0140] When the head 30 is in a portrait mode, the first guide pin
59 may be located at a third point P3 of the first guide groove 43.
The third point P3 may be the other end of the first guide groove
43.
[0141] The distance between the first guide groove 43 and the
penetration groove 34 in the longitudinal direction of the
connecting bar 50 may be the same when the head 30 is in a
landscape mode and a portrait mode.
[0142] More specifically, the distance between the first point P1
and the first groove 35 in a direction parallel with the long sides
32 of the head 30 may be equal to the distance between the second
point P2 and the second groove 36 in a direction parallel to the
short sides 33 of the head 30. That is, when the head is in a
landscape mode, the horizontal distance between the first point P1
and the first groove 35 may be equal to the vertical distance
between the second point P1 and the second groove 36.
[0143] Accordingly, when the head 30 is in a landscape mode and a
portrait mode, distances between the circumferences 32 and 33 of
the head 30 and the stand 20 may be the same. Therefore, the
appearance of the display apparatus may be improved.
[0144] Meanwhile, the first guide groove 43 may include a first
section 44 between the first point P1 and the second point P2 and a
second section 44 between the second point P2 and the third point
P3. The first section 44 and the second section 45 may be
continuously connected.
[0145] In the longitudinal direction of the first guide groove 43,
the length of the first section 44 may be less than that of the
second section 45.
[0146] The first section 44 may be formed to be curved toward the
first groove 35 of the head 30. The distance D1 between the first
section 44 and the first groove 35 may decrease and then increase
from the first point P1 to the second point P2. The distance D1 may
be a distance in a direction parallel with the long side 32 of the
head 30.
[0147] More specifically, the first section 44 may include a first
decreasing section 44a in which the distance D1 decreases and a
second increasing section 44b in which the distance D1 increases,
from the first point P1 to the second point P2 along the first
guide groove 43.
[0148] The first decreasing section 44a may include the first point
P1, and the first increasing section 44b may include the second
point P2. The first decreasing section 44a and the first increasing
section 44b may be continuously connected.
[0149] In the longitudinal direction of the first guide groove 43,
the length of the first decreasing section 44a may be greater than
that of the first increasing section 44b.
[0150] The second section 45 may be formed to be curved toward the
second groove 36 of the head 30. The distance D2 between the second
section 45 and the second groove 36 may decrease and then increase
from the second point P2 to the third point P3. The distance D2 may
be a distance in a direction parallel with the short side 33 of the
head 30.
[0151] More specifically, the second section 45 may include a
second decreasing section 45a in which the distance D2 decreases
and a second increasing section 45b in which the distance D2
increases, from the second point P2 to the third point P3 along the
first guide groove 43.
[0152] The second decreasing section 45a may include the second
point P2 and the second increasing section 45b may include the
third point P3. The second decreasing section 45a and the second
increasing section 45b may be continuously connected.
[0153] In the longitudinal direction of the first guide groove 43,
the length of the second decreasing section 45a may be less than
that of the second increasing section 45b.
[0154] By the trajectory of the first guide groove 43, while the
distances between the circumferences 32 and 33 of the head 30 and
the stand 20 are minimized, the head 30 may be smoothly pivoted
without interfering with the stand 20. In addition, the user may
immediately tilt the head 30 without adjusting the distance between
the head 30 and the stand 20. That is, the user may intuitively
pivot the head 30 without horizontally or vertically moving the
head.
[0155] In a comparative example, in the related art, the user
pulled the head away from the stand to ensure the distance between
the head and the stand before tilting the head of the display
apparatus, tilted the head, and then pushed the head back toward
the stand.
[0156] FIG. 12 is an exploded perspective view of an inner plate
according to an embodiment of the present disclosure.
[0157] The inner plate 40 may include a plate body 41 and a first
guide body 42.
[0158] The plate body 41 may have a metal material. The plate body
41 may be formed of a single metal plate or may be formed by
fastening a plurality of metal plates.
[0159] A penetration portion 41a fastened with the first guide body
42 may be formed in the plate body 41. The penetration portion 41a
may have a shape corresponding to that of the above-described first
guide groove 43.
[0160] In addition, the above-described second guide pin 46 may
protrude from the plate body 41. The second guide pin 46 may be
formed integrally with the plate body 41 or may be formed
independently of the plate body 41 and fastened to the plate body
41.
[0161] For example, the second guide pin 46 may be a boss 47
fastened with a fastening member 47 such as a screw, and a washer
48 may be fitted into the fastening member 47. Referring FIG. 8,
the washer 48 may be located at the opposite side of the inner
plate with the connecting bar 50 interposed therebetween. In
addition, the washer 48 may have a size and shape not to pass
through the second guide groove 58.
[0162] Accordingly, the washer 48 may prevent the second guide pin
from escaping from the second guide groove 58 of the connecting bar
50.
[0163] The first guide body 42 may be fitted into the penetration
portion 41a of the plate body 41, and the above-described first
guide groove 43 may be formed therein. The first guide body 42 may
have a ring shape corresponding to that of the first guide groove
43.
[0164] The first guide body 42 may include a non-metallic material.
More specifically, the first guide body 42 may include a plastic
material. More specifically, the first guide body 42 may include a
polyoxymethylene (POM) material.
[0165] By the material of the first guide body 42, friction between
the inner circumference of the first guide groove 43 and the outer
circumference of the first guide pin 54 (see FIG. 7) may be
reduced. Accordingly, as compared to the case where the first guide
groove 43 is formed in the plate body 41 made of a metal material,
pivot motion of the head 30 may be softly and smoothly
performed.
[0166] FIG. 13 is an exploded perspective view of a connecting bar
according to an embodiment of the present disclosure, and FIG. 14
is a view illustrating connection between a connecting bar and a
stand according to an embodiment of the present disclosure.
[0167] The connecting bar 50 may include a bar body 51 and a second
guide body 57.
[0168] The bar body 51 may have a metal material. The bar body 51
may be formed of a single member or may be formed by fastening a
plurality of members.
[0169] The bar body 51 may include a stand connector 51a connected
to the stand 20, a flange 51b extending from the stand connector
51a, and an extension 51c extending from the flange 51b.
[0170] The stand connector 51a may be rotatably connected to the
stand 20. More specifically, a connection hole 21 may be formed in
the stand 20 and at least a part of the stand connector 51a may be
inserted into the connection hole 21.
[0171] The flange 51b may be located between the circumferences 32
and 33 of the head 30 and the stand 20. The flange 51b may be
formed with a size not to pass through the penetration groove 34 of
the head 30 and the connection hole 21 of the stand 20.
[0172] The extension 51c may extend to the inside of the head 30 by
passing through the penetration groove 34 of the head 30. The cross
section of the extension 51c may be a non-circular. For example,
the cross section of the extension 51c may be approximately
rectangular.
[0173] A long hole 56 fastened with the second guide body 57 may be
formed in the bar body 51. More specifically, the long hole 56 may
be formed in the extension 51c. The long hole 56 may have a shape
corresponding to that of the second guide groove 58.
[0174] In addition, the above-described first guide pin 54 may
protrude from the bar body 51. More specifically, the first guide
pin 54 may protrude from the extension 51c.
[0175] The first guide pin 54 may be formed integrally with the bar
body 51 or may be formed independently of the bar body 51 and
fastened to the bar body 51.
[0176] For example, a fastening hole 54a fastened with the first
guide pin 54 may be formed in the bar body 51, and the washer 55
may be fitted into the first guide pin 54. The first guide pin 54
may include a head portion for preventing escaping of the washer
55.
[0177] The washer 55 may be located at the opposite side of the
connecting bar 50 with the inner plate 40 interposed therebetween.
In addition, the washer 55 may have a size and shape not to pass
through the first guide groove 43 (see FIG. 7).
[0178] Accordingly, the washer 45 may prevent the first guide pin
54 from escaping from the first guide groove 43 of the inner plate
40.
[0179] The second guide body 57 may be fitted into the long hole 56
of the bar body 51, and the above-described second guide groove 58
may be formed therein. The second guide body 57 may have a ring
shape corresponding to that of the second guide groove 58.
[0180] The second guide body 57 may include a non-metallic
material. More specifically, the second guide body 57 may include a
plastic material. More specifically, the second guide body 57 may
include a polyoxymethylene (POM) material.
[0181] By the material of the second guide body 57, friction
between the inner circumference of the second guide groove 58 and
the outer circumference of the second guide pin 46 (see FIG. 8) may
be reduced. Accordingly, as compared to the case where the second
guide groove 58 is formed in the bar body 51 made of a metal
material, pivot motion of the head 30 may be softly and smoothly
performed.
[0182] In addition, at least one of the first guide pin 54 or the
second guide pin 46 may include a non-metallic material, more
specifically, a plastic material, and more specifically, a
polyoxymethylene material.
[0183] In addition, at least one of the washer 55 or 48 (see FIGS.
12 and 13) connected to each guide pin 54 or 46 may include a
non-metallic material, more specifically, a plastic material, and
more specifically, a polyoxymethylene material.
[0184] Therefore, pivot motion of the head 30 may be more softly
and smoothly performed.
[0185] Meanwhile, a passage 54, through which an electric wire W
passes, may be formed in the connecting bar 50. More specifically,
the passage 52 may be formed in the bar body 51.
[0186] The electric wire W may extend from the inside of the base
10 to the inside of the head 30 through the inside of the stand 20.
The electric wire W may be referred to as a wire or a cable.
[0187] For example, a battery may be disposed inside the base 10.
The electric wire W may supply power stored in the battery to the
plurality of electric components installed in the display 31 and
the head 30.
[0188] An internal space 22, through which the electric wire W
passes, may be formed in the stand 20. The internal space 22 of the
stand 20 may vertically extend. That is, the stand 20 may have a
pipe shape having a predetermined inner diameter.
[0189] The passage 52 formed in the connecting bar 50 may guide the
electric wire W to the inside of the head 30.
[0190] More specifically, the passage 52 may include an inlet 52a
penetrating through the stand connector 51a and the flange 51, and
a main passage 52b and an outlet 52c formed in the extension 51c.
The electric wire W may extend to the inside of the head 30 by
sequentially passing through the inlet 52a, the main passage 52b
and the outlet 52c.
[0191] The inlet 52a may enable communication between the internal
space 22 of the stand 20 and the main passage 52b. The inlet 52a
may be a cavity formed over the stand connector 51a and the flange
51b.
[0192] The main passage 52b and the outlet 52c may be located
inside the head 30. The main passage 52b and the outlet 52c may be
recessed in the bar body 51 and, more specifically, one surface of
the extension 51c, which may mean a surface opposed to a surface
facing the inner plate 40.
[0193] The main passage 52b may extend in the longitudinal
direction of the connecting bar 50.
[0194] The outlet 52c may extend from the main passage 52b to the
circumferential surface of the connecting bar 50. The outlet 52c
may extend in a direction perpendicular to the main passage
52b.
[0195] The connecting bar 50 may further include a cover 59
covering the main passage 52b. The electric wire W may pass between
the main passage 52b and the cover 59.
[0196] The cover 59 may also cover the outlet 52c.
[0197] A protrusion 59a having an internal space may be formed on
the cover 59. The protrusion 59a may be formed at a position
adjacent to the outlet 52c. Accordingly, the electric wire W may be
smoothly bent to the outlet 52c in the internal space of the
protrusion 59a.
[0198] Meanwhile, a hook 57a supporting the electric wire W exiting
through the outlet 52c may be formed on the connecting bar 50. A
plurality of hooks 57a spaced apart from each other in the
longitudinal direction of the connecting bar 50 may be
provided.
[0199] More specifically, the hook 57a may be formed on the second
guide body 57. The hook 57a may be connected to the lower edge of
the second guide body 57.
[0200] By the hook 57a, the electric wire may be neatly arranged in
the head 30.
[0201] FIG. 15 is a view showing the inside of a head according to
another embodiment of the present disclosure, and FIGS. 16 and 17
are views illustrating pivot motion of a head according to another
embodiment of the present disclosure.
[0202] The display apparatus according to the present embodiment is
equal to the above-described embodiments except for a mechanism for
pivoting the head 30. Accordingly, a repeated description will be
omitted and a difference will be focused upon.
[0203] The display apparatus according to the present embodiment
may include an inner bracket 60 fixed to the inside of the head 30
and a bracket guide 70 fastened to an end of a connecting bar
50'.
[0204] The inner bracket 60 may be disposed on the center of the
head 30.
[0205] The bracket guide 70 may overlap the inner bracket 40 back
and forth. Hereinafter, the case where the bracket guide 70 is
located behind the inner bracket 60 will be described for
example.
[0206] A pair of guide pins 61 and 62 may protrude from the inner
bracket 60. The pair of guide pins 61 and 62 may protrude backward.
The pair of guide pins 61 and 62 may be spaced apart from each
other. More specifically, the pair of guide pins 61 and 62 may be
spaced apart in a direction (the vertical direction in FIG. 15)
parallel with the short side 33 of the head 30.
[0207] A pair of guide grooves 71 and 72, into which the pair of
guide pins 61 and 62 is inserted, may be formed in the bracket
guide 70. The pair of guide grooves 71 and 72 may extend along
different trajectories.
[0208] More specifically, the pair of guide grooves 71 and 72 may
include a first guide groove 71 extending horizontally and a second
guide groove 72 extending along a curved trajectory. In addition,
the pair of guide pins 61 and 62 may include a first guide pin 61
inserted into the first guide groove 71 and a second guide pin 62
inserted into the second guide groove 72.
[0209] The first guide groove 71 and the second guide groove 72 may
be separated from each other. The length of the first guide groove
71 may be less than that of the second guide groove 72.
[0210] The trajectory of the second guide groove 72 may be formed
such that the distances between the circumferences 32 and 33 of the
head 30 and the stand 20 are the same when the head 30 is in the
landscape mode and the portrait mode.
[0211] At the time of pivot of the head 30, the first guide pin 61
may slide along the first guide groove 71 and the second guide pin
71 may slide along the second guide groove 72. Accordingly, the
head 30, to which the inner bracket 60 is fixed, may be supported
with respect to the bracket guide 70, and pivot motion of the head
30 may be guided.
[0212] The first guide pin 61 may slide between the inner and outer
ends of the first guide groove 71. The second guide pin 62 may
slide between the inner and outer ends of the second guide groove
72.
[0213] The inner end may mean an end far from the stand 20 between
both ends of each guide groove 71 or 72 and the other end may mean
an end close to the stand 20 between both ends of each guide groove
71 or 72.
[0214] The inner end of the first guide groove 71 and the inner end
of the second guide groove 72 may be spaced apart in a vertical
direction and may be located on the same vertical line.
[0215] The outer end of the first guide groove 71 and the outer end
of the second guide groove 72 may be spaced apart in a horizontal
direction and may be located on the same horizontal direction.
[0216] A vertical distance DV between the inner end of the first
guide groove 71 and the inner end of the second guide groove 72 may
be equal to a distance DH between the outer end of the first guide
groove 71 and the outer end of the second guide groove 72.
[0217] As shown in FIG. 15, when the head 30 is in the horizontal
mode, the first guide pin 61 may be located at the inner end of the
first guide groove 71 and the second guide pin 62 may be located at
the inner end of the second guide groove 72.
[0218] That is, when the head is in the portrait mode, the pair of
guide pins 61 and 62 may be spaced apart in the vertical direction
and may be located on the same vertical line.
[0219] As shown in FIG. 16, when the head 30 is being pivoted, the
first guide pin 61 may be located between both ends of the first
guide groove 71 and the second guide pin 62 may be located between
both ends of the second guide groove 72.
[0220] As shown in FIG. 17, when the head 30 is in the portrait
mode, the first guide pin 61 may be located at the outer end of the
first guide groove 71 and the second guide pin 62 may be located at
the outer end of the second guide groove 72.
[0221] That is, when the head 30 is in the portrait mode, the pair
of guide pins 61 and 62 may be spaced apart from each other in the
horizontal direction and may be located on the same horizontal
line.
[0222] According to the preferable embodiment of the present
disclosure, since a pair of guide pins is inserted into a pair of
guide grooves extending along different trajectories to guide pivot
motion of a head, and the heat may be pivoted between in a
landscape mode and a portrait mode. Therefore, it is possible to
determine the pivot trajectory of the head only by a simple
structure.
[0223] In addition, a user can intuitively pivot the head without
horizontally or vertically moving the head.
[0224] In addition, the pivot mechanism of the head is simple and
thus the thickness of the head may be decreased.
[0225] In addition, since the head is supported by the pair of
guide pins, the head may be stably supported without shaking.
[0226] In addition, a guide body in which each guide groove is
formed has a polyoxymethylene (POM) material, the head may be
softly and smoothly tilted.
[0227] In addition, the electric wire may extend from the inside of
the base to the inside of the head by sequentially passing through
the inside of the stand and the passage formed in the connecting
bar. Therefore, since the electric wire is not exposed to the
outside, the appearance of the display apparatus may be neat.
[0228] The above description is merely illustrative of the
technical spirit of the present disclosure, and those of ordinary
skill in the art to which the present disclosure pertains will
appreciate that various modifications and variations are possible
without departing from the essential characteristics of the present
disclosure.
[0229] Therefore, the embodiments disclosed in the present
disclosure are not intended to limit the technical spirit of the
present disclosure, but are intended to describe the embodiments of
the present disclosure, and the scope of the technical spirit of
the present disclosure is not limited by these embodiments.
[0230] The scope of the present disclosure should be interpreted by
the following claims, and all technical spirits within the
equivalent range of the appended claims should be interpreted as
being included in the scope of the present disclosure.
