Description
CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] This non-provisional application claims priority under 35
U.S.C. .sctn.119(a) on Patent Application No. 103221005 filed in
Taiwan, R.O.C. on 2014 Nov. 26, the entire contents of which are
hereby incorporated by reference.
BACKGROUND
[0002] 1. Technical Field
[0003] The present creation relates to a video wall mount, and more
particularly to a video wall mount that can be ejected forward.
[0004] 2. Related Art
[0005] Televisions have increasingly larger sizes and become
increasingly thinner nowadays. To save mounting space and take
overall appearance into consideration, televisions are often
mounted onto a wall by using a wall mount. Moreover, because
televisions have increasingly lower prices, many sellers also
dispose a video wall to present commodities or play advertisements.
As shown in FIG. 1, for a video wall assembled by using multiple
televisions 9, if a floor-type video wall is disposed, a user may
go behind the video wall to dismount or repair a television.
However, in a case of a suspended video wall, a mounting support is
directly locked on a wall, and a user cannot go behind the wall to
perform repair. Meanwhile, to dismount a television located right
in the middle for replacement or repair, adjacent televisions on
the left and right need to be dismounted first to remove the
television right in the middle. Therefore, repair or replacement
becomes very inconvenient.
[0006] At present there are supports movable in a front-rear
direction, and when a television needs to be repaired, a suction
cup is used to hold the surface of a screen to pull out the
television, so that a television support moves outward by certain
repair space for repair or dismounting. However, the use of a
suction cup may cause damages to liquid crystal on the surface of a
television. Additionally, there is also a manner of actuating a
support to move by adding a motor and a gear, so as to operate the
support to move with a remote control to dismount or repair a
television. However, in such a manner, one motor and a needed gear
train need to be configured for every television, resulting in a
very high cost.
SUMMARY
[0007] In view of this, the present creation proposes a video wall
mount, including a first fixing rack, a second fixing rack, and a
folding mechanism. The first fixing rack includes a locking piece
and a magnet piece. The second fixing rack is disposed near a side
of the first fixing rack, and the second fixing rack includes a
rotating arm. The rotating arm includes a pivotal joint, a hook,
and a guiding slope. The pivotal joint is pivotally connected on
the second fixing rack, and the guiding slope is located between
the pivotal joint and the hook. The rotating arm is rotatable about
the pivotal joint being an axis to enable the hook to be
selectively hooked to or unhooked from the locking piece. The
folding mechanism is connected between the first fixing rack and
the second fixing rack.
[0008] A connecting line of the locking piece and the pivotal joint
forms a reference line, and the magnet piece is fixedly disposed on
the first fixing rack and located on the reference line. When the
hook of the rotating arm is selectively hooked to the locking
piece, the first fixing rack is movable more easily relative to the
second fixing rack, so that the locking piece abuts the guiding
slope and moves relatively towards the pivotal joint, so as to
further drive the rotating arm to rotate upward to a near-magnet
point. The near-magnet point refers to that the rotating arm
rotates upward to approach the magnet piece and is subject to a
specific magnetic attraction force. The specific magnetic
attraction force is sufficient to counteract a part of the
gravitation of the rotating arm to extend the time for the rotating
arm to rotate and fall.
[0009] By means of the foregoing structure, the video wall mount of
the present creation intends to use the folding mechanism that can
continuously apply a force for keeping the first fixing rack away
from the second fixing rack, so as to push out a television.
However, after mounting or repair is finished, the first fixing
rack needs to be pushed to and fixed at a position near the second
fixing rack. Therefore, the rotating arm having the hook and the
locking piece are disposed to enable the first fixing rack to be
fixed at a position near the second fixing rack under the effect of
that the hook is hooked to the locking piece when the first fixing
rack is located near the second fixing rack.
[0010] However, in a case of only using a hook to be hooked to the
locking piece, to release a state of being hooked and fixed, the
rotating arm needs to be operated from a side to enable the hook to
leave the locking piece, so that the first fixing rack is subject
to the effect of the folding mechanism again to leave the second
fixing rack and push out a television disposed on the first fixing
rack. However, when the video wall shown in FIG. 1 is assembled, an
operation from a side becomes impossible.
[0011] Therefore, the present creation further uses the magnet
piece for assistance, and calculates interaction among an
attraction force from the magnet piece, a distance between the
magnet piece and the rotating arm, and the gravity. That is, when
the rotating arm is used and pushed upward to a certain distance,
the time for the rotating arm to fall under the effect of
gravitation is extended under the effect of the specific magnetic
attraction force, or even the rotating arm is held by the magnet
piece. When a television needs to be repaired or dismounted, only a
pushing force towards the second fixing rack needs to be applied on
the first fixing rack to enable the hook to rotate upward to leave
a state of being hooked to the locking piece under the effect of a
magnetic force from the magnet piece. In this case, under the
effect of the folding mechanism, the first fixing rack can move in
a direction away from the second fixing rack, instead of making the
first fixing rack be fixed under the effect of the hook.
[0012] When the first fixing rack leaves the second fixing rack,
because the rotating arm located at the second fixing rack loses
the specific magnetic attraction force from the magnet piece
located at the first fixing rack, the rotating arm falls under the
effect of gravitation. In this case, after repair or mounting is
finished, when the first fixing rack is moved near the second
fixing rack again, the hook of the rotating arm is hooked to the
locking piece again to enable the first fixing rack to be fixed at
a position near the second fixing rack.
[0013] Accordingly, by means of a simple mechanical structure, a
video wall mount can be folded backward and fixed or pushed forward
without needing to use a suction cup or disposing a mechanism such
as a motor that is high in unit price. Moreover, when metal
elements such as the magnet piece and the rotating arm are used, a
problem of damages after long time of use also does not easily
occur, and elements have very low manufacturing costs, assembly is
easy, and use is also very simple.
[0014] The foregoing first fixing rack and second fixing rack may
be disposed in parallel to each other. A parallel four-bar linkage
mechanism may be formed among the first fixing rack, the second
fixing rack, and the folding mechanism. The magnet piece disposed
at the first fixing rack may be a permanent magnet, or may also be
an element or a component, for example, an electromagnet, that has
magnetism or can generate the specific magnetic attraction force.
The guiding slope of the foregoing rotating arm may be a linear
slope, or may also be a nonlinear curved surface.
[0015] The foregoing second fixing rack may further include at
least one stop piece to stop the rotating arm to avoid excessive
rotation of the rotating arm. The number of at least one stop piece
may be two, one of which is an upper stop piece, and the other is a
lower stop piece, and the upper stop piece and the lower stop piece
are disposed on an upper side and a lower side of the pivotal joint
of the rotating arm, respectively.
[0016] The foregoing folding mechanism may include a reset spring
for providing a preload to enable the first fixing rack to leave
the second fixing rack. The rotating arm may be subject to the
effect of the specific magnetic attraction force until the rotating
arm is attracted by the magnet piece. The rotating arm is
temporarily attracted to the magnet piece, that is, the hook of the
rotating arm is enabled to temporarily leave the locking piece by a
certain distance.
[0017] The detailed features and advantages of the present creation
are described below in the implementation manners, and the content
of the description is sufficient for any person skilled in the art
to understand the technical content of the present creation and
implement the present creation accordingly. According to the
content disclosed in the specification, the claims, and the
accompanying drawings, any person skilled in the art can readily

DETAILED DESCRIPTION
[0029] Referring to FIG. 2 to FIG. 10, FIG. 2 is a schematic view
of a video wall mount according to an embodiment of the present
creation; FIG. 3 is a schematic view of the video wall mount being
located at a folded position; FIG. 4 to FIG. 8 are partial enlarged
views (1) to (5) showing actions of a rotating arm; FIG. 9 is a
schematic view of the video wall mount being located at an unfolded
position; and FIG. 10 is a partial enlarged view showing a folding
action of the video wall mount.
[0030] As shown in FIG. 2 and FIG. 3, the video wall mount in this
embodiment includes a first fixing rack 1, a second fixing rack 2,
and a folding mechanism 3. The second fixing rack 2 of video wall
mount is locked on a wall 5, and a television 4 is disposed to the
first fixing rack 1. In this embodiment, two sets of video wall
mounts are used and mounted on the rear of televisions, and the
television is actuated to move in a manner of applying even forces
at two sides. A connecting support 6 may further be disposed
between the two sets of video wall mounts. As shown in FIG. 2, the
second fixing rack 2 is disposed near a side of the first fixing
rack 1, and herein the first fixing rack 1 and the second fixing
rack 2 are disposed in a manner of being parallel to each other.
The position relationship shown in FIG. 2 is used for description,
and the first fixing rack 1 is located in front of the second
fixing rack 2. Next, the relative position relationships of front
and rear in the following description are all based on the position
relationship shown in FIG. 2. Movement towards the rear is a
pushing direction, and movement towards the front is a removing
direction.
[0031] Referring to FIG. 8 together, the folding mechanism 3 is
connected between the first fixing rack 1 and the second fixing
rack 2, so as to provide a preload for the first fixing rack 1 to
leave the second fixing rack 2. In this embodiment, the folding
mechanism 3 includes a reset spring 31 to provide a preload to
enable the first fixing rack 1 to leave the second fixing rack 2.
As shown in FIG. 8, a parallel four-bar linkage mechanism is formed
among the first fixing rack 1, the second fixing rack 2, and the
folding mechanism 3. The reset spring 31 actuates a linkage
mechanism to convert elastic restoring forces that are presented in
vertical directions along the reset spring 31 into a preload in a
direction perpendicular to the reset spring 31.
[0032] Referring to FIG. 3 and FIG. 4, the first fixing rack 1
includes a locking piece 11 and a magnet piece 12. Herein, a
permanent magnet is adopted for the magnet piece 12. In other
implementation aspects, the magnet piece 12 may also be an element
or a structure, for example, an electromagnet, that can generate a
specific magnetic attraction force. The second fixing rack 2
includes a rotating arm 21, and the rotating arm 21 includes a
pivotal joint 211, a hook 212, and a guiding slope 213. The pivotal
joint 211 is pivotally connected on the second fixing rack 2, the
rotating arm 21 can rotate about the pivotal joint 211 being an
axis to enable the hook 213 to be selectively hooked to or unhooked
from the locking piece 11. The guiding slope 213 is located between
the pivotal joint 211 and the hook 212, and in this embodiment, the
guiding slope 213 is a linear slope. A connecting line of the
locking piece 11 and the pivotal joint 211 forms a reference line
22, and the magnet piece 12 is fixedly disposed on the first fixing
rack 1 and located above the reference line 22.
[0033] Next, FIG. 3 to FIG. 8 are used to describe the actions of
the video wall mount and the rotating arm 21. When the television 4
has been assembled, the video wall mount is pushed to a folded
position shown in FIG. 3, and the hook 213 of the rotating arm 21
is hooked to the locking piece 11, as shown in FIG. 4. In this
case, although the folding mechanism 3 located between the first
fixing rack 1 and the second fixing rack 2 still continuously
provides a preload, under the effect of that the hook 213 is hooked
to the locking piece 11, the first fixing rack 1 and the second
fixing rack 2 may still be kept in a folded state. When the
television 4 needs to be pushed to the position shown in FIG. 9 to
repair or dismount the television 4, as shown in FIG. 5, a pushing
force F is first applied on the first fixing rack 1. When the first
fixing rack 1 is subject to the effect of the pushing force F to
move towards the second fixing rack 2, the locking piece 11 located
on the second fixing rack 2 abuts the guiding slope 213 of the
rotating arm 21 and moves relatively towards the pivotal joint 211.
Meanwhile, under the effect of abutting of the locking piece 11,
the rotating arm 21 is driven to rotate upward to a near-magnet
point. The so-called near-magnet point refers to that the rotating
arm 21 rotates upward to approach the magnet piece 12 and is
subject to a specific magnetic attraction force M. When the
rotating arm 21 rotates upward to the near-magnet point, the
specific magnetic attraction force M is sufficient to counteract a
part of the gravitation W of the rotating arm 21 to extend the time
for the rotating arm 21 to rotate and fall.
[0034] In this embodiment, to avoid an excessive thrust caused by
the pushing force F and enable the rotating arm 21 to directly
rotate clockwise being pushed by the locking piece 11 to exceed the
range of the magnetic attraction force from the magnet piece 12,
the second fixing rack 2 includes a stop piece to stop the rotating
arm 21 to avoid excessive rotation of the rotating arm 21, and in
this embodiment, an upper stop piece 241 located at a position
above the rotating arm 21.
[0035] As shown in FIG. 6, the rotating arm 21 rotates to the
near-magnet point, and under the effect of the specific magnetic
attraction force M, an end 214 of the rotating arm 21 is directly
attracted by the magnet piece 12 to enable the hook 213 of the
rotating arm 21 to leave the locking piece 11. In this case, the
pushing force F is then released, and because the force of the hook
213 being hooked to the locking piece 11 no longer exists, a first
fixing piece 1 moves in a direction away from a second fixing piece
2 under the effect of the preload provided by the folding mechanism
3. As shown in FIG. 7, when the first fixing piece 1 moves, the
magnet piece 12 located at the first fixing piece 1 is also
actuated to leave the second fixing piece 2. When the distance of
movement already exceeds the range of the specific magnetic
attraction force M provided by the magnet piece 12, the rotating
arm 21 loses the effect of the specific magnetic attraction force
M, and rotates downward and falls under the effect of the
gravitation W.
[0036] Because when the rotating arm 21 falls, the locking piece 11
has already left the range in which the hook 213 can be hooked, so
that the fallen hook 213 of the rotating arm 21 is not hooked to
the locking piece 11, as shown in FIG. 8. Therefore, the first
fixing piece 1 may move till the position shown in FIG. 9 under the
effect of the preload of the folding mechanism 3 to repair,
assemble or dismount the television 4.
[0037] Accordingly, by means of a simple mechanical structure, a
video wall mount can be folded backward and fixed without needing
to use a suction cup or disposing a mechanism such as a motor that
is high in unit price to push out the video wall mount. Moreover,
when metal elements such as the magnet piece and the rotating arm
are used, a problem of damages after long time of use also does not
easily occur. Moreover, the foregoing elements have very low
manufacturing costs, assembly is easy, and use is also very
simple.
[0038] Subsequently, the first fixing rack 1 still needs to be
moved towards the second fixing rack 2 to a folded position.
Therefore, the rotating arm 21 needs to be kept at the position
shown in FIG. 8, so that when the first fixing rack 1 is moved near
the second fixing rack 2, the hook 213 of the rotating arm 21 is
hooked to the locking piece 11 again. Therefore, the second fixing
piece 2 may further include a lower stop piece 242 located at a
position below the rotating arm 21. When the rotating arm 21 falls
as shown in FIG. 7 and FIG. 8, the rotating arm 21 stops at the
position shown in FIG. 8 being stopped by the lower stop piece
242.
[0039] Further, referring to FIG. 10, when the video wall mount
needs to be moved from an unfolded position (as shown in FIG. 9) to
a folded position (as shown in FIG. 3), a pushing force F is
applied on the first fixing rack 1 again to enable the first fixing
rack 1 to move towards the second fixing rack 2. In this case, the
locking piece 11 pushes the rotating arm 21 to rotate upward till
the hook 213 of the rotating arm 21 is hooked to the locking piece
11 again.
[0040] While the instant disclosure has been described by the way
of example and in terms of the preferred embodiments, it is to be
understood that the invention need not be limited to the disclosed
embodiments. On the contrary, it is intended to cover various
modifications and similar arrangements included within the spirit
and scope of the appended claims, the scope of which should be
accorded the broadest interpretation so as to encompass all such
modifications and similar structures.
