DETAILED DESCRIPTION OF THE INVENTION
[0022] Exemplary embodiments of the present invention will now be
described in detail with reference to the annexed drawings. In the
following description, a detailed description of known functions
and configurations incorporated herein has been omitted for
conciseness.
[0023] As shown in FIGS. 1 to 7, an automatic wall mounting system
for a wall-mounted television (TV) according to an exemplary
embodiment of the present invention includes a support plate 10
mounted on a wall body 2; a tilt plate 20 mounting the TV 4 in its
front; and a tilt manipulation unit 30 coupled with each of the
support plate 10 and the tilt plate 20, and tilting up/down an
upper end of the tilt plate 20 about the support plate 10.
[0024] The support plate 10 is of a board shape in which it is
mounted on the wall body 2, and has a plurality of upper and lower
supports 12 and 14 each provided at its front upper and lower
sides. In particular, the support plate 10 can be separately fixed
to the wall body 2 using coupling holes (not shown) provided at
both ends that are bent and step-shaped. Alternately, the support
plate 10 can be coupled to a separate elevating unit (not shown)
previously fixed and installed at the wall body 2 to elevate or
descend.
[0025] The upper supports 12 of the support plate 10 face with each
other at their both front and upper sides. The upper supports 12
each have through-holes 12a for rotatably inserting both ends of a
rotary shaft 34 of the tilt manipulation unit 30, respectively.
[0026] The lower supports 14 of the support plate 10 are disposed
in parallel on the same horizontal line. The lower supports 14 have
through-holes 14a obtained by up/down penetration, and rotatably
insert joint protrusions 24a of both lower joints 24 of the tilt
plate 20.
[0027] The tilt plate 20 is of a board shape in which it has a
plurality of upper and lower joints 22 and 24 in its rear
correspondingly to the upper and lower supports 12 and 14 of the
support plate 10, and installs the TV 4 in its front.
[0028] The upper joint 22 is a ball joint with a guide socket 22a.
The guide socket 22a covers and turns around a ball, and connects
with a connection link 34a of the tilt manipulation unit 30.
[0029] The lower joint 24 is a ball joint with the joint protrusion
24a. The joint protrusion 24a is provided and supported at one side
on a circumferential surface of the ball, passing through the
through-hole 14a of the lower support 14 of the support plate
10.
[0030] The tilt manipulation unit 30 includes a motor 31 provided
in front of the support plate 10, and having a rod 31a rotating
forward and backward; a gear box 32 provided at an end of the rod
31a of the motor 31, and converting an axial rotation force of the
rod 31a into a vertical rotation force; a retractable unit 33
connecting at one end with the gear box 32, and retracting up/down
at the other end as the rod 31a rotates forward or backward; and
the rotary shaft 34 connecting with an upper end of the retractable
unit 33, and rotating forward or backward as supported at its both
ends by the support plate 10, and having the connection link 34a on
its circumferential surface. The connection link 34a connects with
the tilt plate 20, and pushes and pulls the tilt plate 20 as
tilting up/down by a hinge.
[0031] The retractable unit 33 includes a male screw part 33a
connecting with the rod 31a via the gear box 32, and rotating at
its place; and a female screw part 33b covering and screwing with
the male screw part 33a, and moving up/down as the male screw part
33a rotates forward/backward.
[0032] The gear box 32 connects the rod 31a with the male screw
part 33a by a worm gear manner. In other words, worm gears connect
to ends of the rod 31a and the male screw part 33a interconnecting
with each other, respectively. The worm gears are geared with each
other, and transmit the rotation force of the rod 31a to the male
screw parts 33a disposed in a vertical direction.
[0033] In addition to the worm gear, the gear box 32 can apply a
combination of various gears such as a rack pinion gear or a bevel
gear for converting the rotation force into the vertical rotation
force.
[0034] The rotary shaft 34 having a rod shape is rotatably inserted
at its both ends and supported in the through-holes 12a of the both
upper supports 12 of the support plate 10. The rotary shaft 34 has
the connection link 34a at its center part. The connection link 34a
is coupled at its both ends to the rotary shaft 34 and the guide
socket 22a of the upper joint 22 of the tilt plate 20. The
connection link 34a is connected by a hinge at its center part and
thus, has a "V"-shape. The connection link 34a pulls and pushes the
tilt plate 20 as folded and unfolded when the rotary shaft 34
rotates forward and backward.
[0035] A hinge fragment 35 is provided between an upper end of the
female screw part 33b of the retractable unit 33 and the rotary
shaft 34. The hinge fragment 35 is integrally connected with the
rotary shaft 34, and is hinged and connected with the female screw
part 33b.
[0036] The automatic wall mounting system for a wall-mounted TV
according to an exemplary embodiment of the present invention is
completely assembled as follows. First, the support plate 10 is
fixingly mounted on the wall body 2. After that, the tilt
manipulation unit 30 is disposed in front of the support plate 10
such that the rotary shaft 34 is rotatably inserted and supported
by the upper support 12 of the support plate 10. Next, the tilt
plate 20 covers a front surface of the tilt manipulation unit 30.
Thus, the guide socket 22a of the upper joint 22 of the tilt plate
20 connects with the connection link 34a of the tilt manipulation
part 30. At the same time, the joint protrusion 24a of the lower
joint 24 is inserted into and supported in the through-hole 14a of
the lower support 14 of the support plate 10.
[0037] In this state, a viewer can control an up/down tilt angle of
the screen of the TV 4 at his/her eye level in a remote place,
using a remote controller.
[0038] For example, when it is intended to tilt down the screen of
the TV 4, the motor 31 is driven to rotate the rod 31a in a desired
direction. The rotation force of the rod 31a serves to push upward
the female screw part 33b of the retractable unit 33 disposed in
the vertical direction through the gear box 32. The rotary shaft 34
is rotated in engagement connecting with the female screw part 33b
by the hinge fragment 35. Thus, the connection link 34a extends to
the front. Because the tilt plate 20 is hinged and fixed at its
lower end, the connection link 34 extends in a "V"-shape while
pushing an upper end of the tilt plate 20 to the front, thereby
tilting down the screen of the TV by the hinge.
[0039] As described above, the automatic wall mounting system for a
wall-mounted TV according to an exemplary embodiment of the present
invention has an effect of automatically tilting up/down the screen
of the TV at a viewer's eye level in a remote place, thereby
providing an optimal screen position to the viewer in real time
while promptly, simply, and conveniently tilting up/down the screen
by automation.
[0040] While the invention has been shown and described with
reference to a certain preferred embodiment thereof, it will be
understood by those skilled in the art that various changes in form
and details may be made therein without departing from the spirit
and scope of the invention as defined by the appended claims.
