Description

Balanced Moving Wall Mount for Display Devices

[0001] The present invention relates to a wall mount applied to a display device, and more specifically, to a balanced moving wall mount for a display device that can freely change the posture mode of the display device by attaching the display device to a wall, tilting the display device up and down with respect to the wall, and swivelling the display device left and right, while stably maintaining the posture of the display device in a balanced manner when it has been switched to the tilting mode.

[0002] Generally, liquid crystal display devices, plasma display devices, field emission display devices, and light emitting display devices are being actively researched as flat panel display devices, but liquid crystal display devices and light emitting display devices are receiving the spotlight due to their advantages of mass production technology, ease of driving means, and implementation of high definition.

[0003] These display devices are becoming increasingly high-resolution and larger, while also becoming thinner and lighter.

[0004] Display devices that are becoming larger and thinner are installed on the walls of living rooms or other indoor spaces using a separate device such as a wall mount. When a display device is installed on a wall using a wall mount, the display device is fixed to the wall at a distance from the wall equal to the thickness of the wall mount.

[0005] When a display device is separated from the wall by a wall mount, creating a gap, the display device does not give the user the feeling of being integrated with the wall, and the rear of the display device is exposed to the user through the top, bottom, left, and right sides, which causes an unsightly problem.

[0006] (Patent Document 1) KR10-2009-0130549 A

[0007] Patent Document 1 discloses a support device for a display device, which includes a fixing part fixed to a fixed position, a device mounting part on which a display device is installed, and a sliding unit interposed between the fixing part and the device mounting part, the sliding unit being composed of a plurality of sliding members and allowing the device mounting part to move back and forth with respect to the fixing part as the length of the member is varied.

[0008] However, the wall mount, which is a support device of Patent Document 1, can perform a tilting mode in which the viewing angle is adjusted in the up-and-down direction by a tilting operation in which the display device is tilted forward and backward at a certain angle with respect to the wall, but it cannot perform a swivel mode in which the viewing angle is adjusted in the left-right direction by a swivel operation in which the display device is tilted left-right at a certain angle with respect to an imaginary vertical axis, and a close-contact mode in which the display device is pressed as close as possible to a vertical wall, which causes inconvenience in use.

[0009] In addition, if the display device is large, 60 inches or larger, and the center of gravity of the heavy display device and the tilting rotation center of the wall mount are not close to each other but are far apart, the display device tilted upward or downward will sag downward due to its own weight moment, making it impossible to stably maintain the tilt-adjusted viewing angle, resulting in inconvenience in use.

[0010] The present invention is to solve the above-mentioned problem, and the purpose of the present invention is to provide a wall mount for a display device that can freely and easily perform a tilting mode in which the display device is tilted up and down with respect to a wall to adjust the viewing angle in the up and down direction or to secure rear space, and a swivel mode in which the display device is tilted left and right to adjust the viewing angle in the left and right direction or to secure side space.

[0011] Another object of the present invention is to provide a wall mount for a display device that can prevent the sagging of a tilt-adjusted display device by compensating for sagging due to the self-weight moment of the display device, which is a heavy object.

[0012] The technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0013] According to one aspect of the present invention, there is provided a display device comprising: a back bracket fixedly installed on the back of a display device; a wall bracket fixedly installed on a wall surface on which the display device is to be mounted; and a connecting bracket connecting the back bracket and the wall bracket so that the back bracket can rotate up and down and left and right with respect to the wall bracket. The present invention provides a balanced moving wall mount for a display device, which includes a pair of first connecting plates, one end of which is connected to the back bracket and the tilting guide via the connecting bracket, and a pair of second connecting plates, one end of which is connected to the other end of each of the pair of first connecting plates via the second swivel axis and the other end of which is connected to the wall bracket via the third swivel axis, so that the back bracket performs a tilting mode in which the back bracket rotates up and down around the tilting axis provided in the tilting guide to tilt the display device up and down at a predetermined angle, and a swivel mode in which the first connecting plate and the second connecting plate rotate left and right around any one of the first swivel axis, the second swivel axis, and the third swivel axis provided in the tilting guide to tilt the display device left and right at a predetermined angle.

[0014] At this time, the tilting guide part may include a rotating block having a first swivel shaft formed at the upper and lower ends and connected to the first connecting plate through a first central hole, a fixed block formed at the upper and lower ends and connected to the second central hole corresponding to the first central hole and fixed to the back bracket, and a torque control member that is fastened to an end of the tilting shaft exposed through the first and second central holes and controls a frictional force generated between the rotating block and the fixed block at a contact surface.

[0015] At this time, the rotating block and the fixed block may protrude a pair of arc-shaped guide ribs arranged vertically around the tilting axis on one of the two contact surfaces that contact each other, and may recess a pair of arc-shaped guide grooves arranged on the other contact surface to guide movement by arranging the pair of arc-shaped guide ribs.

[0016] At this time, the tilting guide may include at least one restraining pin that is caught or separated from a restraining arc-shaped hole formed through the rotating block by passing through the back bracket and the fixed block to restrain or release the rotation of the rotating block.

[0017] At this time, the torque adjusting member may have a recessed groove formed at the end to enable tightening and loosening operations using the same hand tool.

[0018] At this time, the torque adjusting member may be formed into a multi-faceted cross-section so that the body can be tightened and loosened using a hand tool.

[0019] At this time, the display device includes a balance maintenance unit that prevents it from sagging downward due to its own weight moment, and the balance maintenance unit includes upper and lower horizontal axes fixedly installed on the back bracket so as to be positioned above and below the tilting axis at a certain interval, upper and lower torsion springs respectively provided on the upper and lower horizontal axes, and upper and lower horizontal axes having one end fixed to a rotation block provided on the tilting guide unit by passing through upper and lower arc-shaped guide holes formed through the back bracket and the fixing block, and each end of the upper and lower torsion springs is hooked and connected to the back bracket, and each other end of the upper and lower torsion springs is hooked and connected to each other end of the upper and lower horizontal axes so as to elastically support the upper and lower portions of the rotation block in opposite directions with respect to the tilting axis.

[0020] According to the above configuration, the balance moving wall mount for a display device according to the present invention can adjust the viewing angle of the display device in tilting mode or easily connect a cable to the display device through the secured rear space.

[0021] Equipped with a balance maintenance unit with upper and lower torsion springs, it prevents the tilt-adjusted display device from sagging downward due to its own weight moment when in tilt mode, thereby stably maintaining the tilt-adjusted viewing angle, and allows for easy cable connection through the secured rear space of the display device tilted at a certain angle.

[0022] The display device can be freely and easily changed in posture in the close mode, which allows the rear surface of the display device to be pressed against or separated from a wall without creating a space, in the tilt mode, which allows the display device to be tilted at a certain angle with respect to a vertical wall, and in the swivel mode, which allows the display device to be tilted left and right.

[0046] A balance moving wall mount (100) for a display device according to an embodiment of the present invention, as shown in FIGS. 1a, 1b, 2a, 2b and 3, is provided between a display device (not shown) and a wall surface (W) to adjust the viewing angle of a large and heavy display device or to secure a rear space or a side space, and may include a back bracket (10), a wall bracket (20), a connection bracket (30) and a tilting guide (40) so that the display device can freely perform a tilting mode in which the display device is tilted up and down with respect to a vertical wall surface, a swivel mode in which the display device is tilted left and right, and a close mode and a separate mode in which the display device is brought close to or spaced from the wall surface.

[0047] The above back bracket (10) is a frame structure (not shown) provided on the back of a display device to be mounted by a plurality of fastening members through which a plurality of assembly holes (11a, 11b) are formed, as shown in FIGS. 3, 4 and 5, or a plate structure having a substantially square frame shape that is integrally fixed to the back of the display device.

[0048] This back bracket (10) can form an approximately square space in which a connecting bracket (30) is arranged, which is made up of a pair of vertical frames (13) that are integrally connected to the left and right ends of the upper and lower horizontal frames (11, 12) and first and second connecting plates (31, 32) that are folded and overlapped together with the wall bracket in the close mode.

[0049] A pair of vertical frames (13) facing each other may include a recessed arrangement portion (15) on each inner side of the middle of the length so that a tilting guide portion (40) that is combined with the first connecting plate of the connecting bracket is arranged and installed.

[0050] The above wall bracket (20) is fixedly installed on a wall surface on which the display device is to be installed, as shown in FIGS. 1a, 1b, 2a, 2b and 3, and may include an upper horizontal member (21) having a plurality of fixing holes (21a) formed therethrough, and a lower horizontal member (22) having a plurality of fixing holes (22a) formed therethrough.

[0051] These upper and lower horizontal bars (21, 22) can be provided as a frame structure having a cross-section shape of approximately ㄷ, with a plurality of fixing holes (21a, 22a) formed through which anchor bolts (23) anchored to the wall are penetrated and fastened.

[0052] The two ends of the upper and lower horizontal bars (21, 22) are connected via a pair of second connecting plates (32) and a third swivel axis (35) provided in the connecting bracket (20) to enable swivel mode operation for tilting the display device left and right, so that the connecting bracket (20) can be assembled to rotate left and right about an imaginary vertical axis passing through the third swivel axis.

[0053] As shown in FIGS. 1a, 1b, 2a, 2b and 3, the above connecting bracket (30) may include a pair of first connecting plates (31) and a pair of second connecting plates (32) that connect the back bracket (10) and the wall bracket (20) so that the back bracket (10) coupled with the display device can rotate in the up-down and left-right directions with respect to the wall bracket (20) fixedly installed on the wall surface.

[0054] A pair of first connecting plates (31) and a pair of second connecting plates (32) may be provided in a left-right symmetrical structure with respect to an imaginary vertical line passing vertically through the center of the back bracket.

[0055] The above first connecting plate (31) is a roughly triangular plate structure whose one end is rotatably connected to the back bracket (10) via a tilting guide (40) including a first swivel axis (33) and a tilting axis (41), respectively.

[0056] At this time, it is preferable that the tilting guide (40) be installed on an installation surface that is formed by recessing in the middle of the length of the vertical frame (13) of the back bracket corresponding to the protruding end of the first connecting plate.

[0057] One end of the first connecting plate (31) corresponding to the middle of the length of the vertical frame (13) is rotatably connected via the first swivel shaft (33), and the first swivel shaft (33) connected to one end of the first connecting plate (31) is connected to a rotation block (42) of a tilting guide part (40) that is rotatably assembled via the vertical frame (13) and the tilting shaft (41), so that the first connecting plate (31) can rotate left and right around the first swivel shaft (33) provided in the tilting guide part (40) or rotate up and down together with the rotation block (42) around the tilting shaft (41) provided in the tilting guide part (40) as the rotation center.

[0058] At this time, the first swivel shaft (33) includes upper and lower pin members provided at the upper and lower ends of the rotation block (42) provided in the tilting guide part (40), as shown in FIG. 4, and the first swivel shaft (33) can be replaced and assembled by a set screw member that is fastened to a pin hole formed in the upper and lower ends of the rotation block (42).

[0059] The above tilting axis (41) may include a shaft member of a certain length that horizontally penetrates and connects the rotating block (42), the fixed block (43) assembled thereto, and the vertical frame (13).

[0060] The second connecting plate (32) is a roughly square plate structure in which one end is rotatably connected to the other end of the first connecting plate (31) via a second swivel shaft (34), and the other end of the second connecting plate (32) is rotatably connected to the upper and lower horizontal bars (21, 22) of a wall bracket (20) fixedly installed on the wall surface via a third swivel shaft (35).

[0061] The above second swivel shaft (34) may include upper and lower pin members that are connected to form a vertical rotation axis at the upper and lower ends, respectively, in which the other end of the first connecting plate having a wide width and one end of the second connecting plate (32) having a corresponding wide width overlap each other.

[0062] The third swivel shaft (35) may include upper and lower pin members that are connected to each other to form a vertical rotation axis at the upper and lower ends where the other end of the second connecting plate (32) having a wide width and the upper and lower horizontal bars (21, 22) overlap each other.

[0063] The second swivel shaft (34) rotatably connecting the other end of the first connecting plate (31) and one end of the second connecting plate (32), and the third swivel shaft (35) rotatably connecting the other end of the second connecting plate (32) and the upper and lower horizontal bars (21, 22) are illustrated and described as being made of upper and lower pin members that are respectively fastened to the upper and lower overlapping portions, but are not limited thereto, and may be made of a vertical shaft member of a certain length that vertically penetrates and is connected to the upper and lower overlapping portions.

[0064] In addition, the upper and lower outer edges of the first connecting plate (31) and the upper and lower outer edges of the second connecting plate (32) include first and second flanges (31a, 32a) extending in directions facing each other, and it is preferable to form an embossing portion protruding inward on each inner surface of the first and second flanges, which are folded and overlapped around the second swivel axis (34) in the close mode, so as to contact each other and generate frictional force when overlapped in the close mode.

[0065] Accordingly, the back bracket coupled with the display device can perform a tilting mode in which the display device is tilted up and down by rotating up and down around a horizontal tilting axis provided in the tilting guide.

[0066] At the same time, the first and second connecting plates can perform a swivel mode in which the display device is tilted left and right at a certain angle with respect to a vertical wall by rotating left and right around any one of the first swivel axis, the second swivel axis, and the third swivel axis provided in the tilting guide.

[0067] FIG. 4 is a perspective view showing a state of coupling between a back bracket and a connecting bracket of a balance moving wall mount for a display device according to an embodiment of the present invention, FIG. 5 is a perspective view showing a tilting guide provided on a back bracket of a balance moving wall mount for a display device according to an embodiment of the present invention, FIGS. 6a and 6b are detailed views showing a state of coupling between a back bracket and a connecting bracket via a tilting guide of a balance moving wall mount for a display device according to an embodiment of the present invention, FIGS. 7a and 7b are exploded perspective views showing a tilting guide of a balance moving wall mount for a display device according to an embodiment of the present invention, and FIG. 8 is a cross-sectional perspective view showing a tilting guide of a balance moving wall mount for a display device according to an embodiment of the present invention.

[0068] The above tilting guide (40) may include, as shown in FIGS. 4, 5, 6a, 6b, 7a, 7b and 8, a rotating block (42) that rotates around the tilting axis (41) as a center of rotation, a fixed block (43) that is fixedly installed on the vertical frame (13) of the back bracket (10), and a torque control member (44) that controls the frictional force generated between the contact surface between the rotating block (42) and the fixed block (43).

[0069] The above-mentioned rotation block (42) is a block member having a first central hole (42a) formed through the center of the body, into which the tilting axis (41) is inserted horizontally and penetrates, and a first swivel axis (33) vertically provided at the upper and lower ends, which is rotatably connected to the first connecting plate (31).

[0070] At this time, the tilting axis (41) may include an approximately D-shaped shaft member having a flat surface (41a) cut out on the outer surface to interface with a flat surface formed on the inner surface of the first central hole so that no idle rotation occurs in the first central hole when combined with the rotating block.

[0071] The above fixed block (43) is a plate-shaped block member that is formed through the center of the body with a second central hole (43a) corresponding to the first central hole so that the tilting axis can pass through, and is fixedly installed on a mounting surface formed in the middle of the length of the vertical frame (13) by a plurality of fastening members by having one side in contact with the rotating block (42).

[0072] The above torque control member (44) is a control member that is fastened to the end of the tilting shaft that is exposed to the outside through the first and second central holes, thereby controlling the frictional force generated at the contact surface between the rotating block (42) and the fixed block (43) to increase or decrease in proportion to the amount of rotation when the torque control member is tightened or loosened.

[0073] FIG. 9 is a diagram illustrating a state of use for torque adjustment of a tilting axis in a tilting guide part of a balance moving wall mount for a display device according to an embodiment of the present invention. As shown in FIG. 9, an operating groove can be formed in the end of the torque adjusting member (44) to enable tightening and loosening operations of the torque adjusting member (44) using a hand tool such as a wrench (T1) or a screw driver (T2).

[0074] In addition, it is preferable that the body of the torque adjusting member (44) be formed as a body with a polygonal cross-section such as a hexahedron so that tightening and loosening operations of the torque adjusting member (44) can be performed using other hand tools such as a spanner (T3).

[0075] An elastic insert (44a) such as a disk washer or coil spring may be included between the torque control member (44) and the vertical frame (13) to maintain a constant torque due to friction between the contact surfaces of the rotating block and the fixed block.

[0076] Accordingly, the user can adjust the frictional force generated at the contact surface between the rotating block and the fixed block by tightening the torque adjusting member in the fastening direction or loosening the torque adjusting member in the loosening direction using a hand tool such as the wrench or screwdriver or another hand tool such as the spanner, thereby smoothly or tightly performing the tilting operation for tilting the display device combined with the back bracket in the up-and-down direction with the tilting axis as the center of rotation.

[0077] In addition, the tilting guide (40) may include a guide structure that applies an arc-shaped guide rib (42c) and an arc-shaped guide groove (43c) to prevent shaking that occurs during tilting rotation of the rotating block between the rotating block (42), which is a movable body that rotates up and down together with the first connecting plate (31), and the fixed block (43), which is a fixed body fixedly installed on the vertical frame of the back bracket (10), so as to stably perform the tilting mode.

[0078] That is, the above-mentioned rotary block and fixed block can protrude a pair of arc-shaped guide ribs (42c) arranged vertically with the tilting axis (41) as the center on one side of the contact surface of the rotary block among the two contact surfaces that contact each other, and can recess a pair of arc-shaped guide grooves (43c) arranged in the other side of the contact surface of the fixed block (43) to guide movement by arranging the pair of arc-shaped guide ribs (42c).

[0079] At this time, the pair of arc-shaped guide ribs (42c) are formed protrudingly on one side of the rotating block, and the pair of arc-shaped guide grooves (43c) are formed recessedly on one side of the fixed block (43) facing them, but this is not limited to this, and they may be formed opposite to each other.

[0080] In addition, the tilting guide (40) may include at least one restraining pin (46) that restrains or releases the rotation block (42) that rotates about the tilting axis (41) relative to the fixed block by being caught or separated by a restraining arc-shaped long hole (42b) formed in an arc shape through a through hole formed in the vertical frame (13) of the back bracket on which the fixed block is fixedly installed and by passing through another through hole of the fixed block.

[0081] It is preferable that the above-mentioned restraint-shaped hole (42b) be formed in a roughly arc shape adjacent to the above-mentioned arc-shaped guide rib (42c) and have a wave-shaped protrusion formed on the inner surface so that restraint pins with a circular cross-section can be caught at a set interval.

[0082] Accordingly, when the tip of the restraining pin passes through the vertical frame and the fixed block and is caught by the wave-shaped projection formed inside the restraining arc-shaped hole of the rotating block, the rotation of the rotating block is constrained around the tilting axis as the center of rotation by the catch between the restraining pin and the rotating block, thereby limiting unnecessary tilting movement of the display device due to external force.

[0083] Conversely, when the restraining pin is separated and the engagement between the restraining hook and the rotation block is released, the tilting mode can be performed to tilt the display device up and down by allowing the rotation of the rotation block around the tilting axis as the center of rotation by releasing the engagement of the restraining pin.

[0084] Meanwhile, a balance maintenance unit (50) may be included to prevent the display device, which is adjusted in the tilting mode in the upward or downward direction due to the self-weight moment of the heavy display device, from sagging downward, thereby maintaining the tilt-adjusted angle constant and stable.

[0085] This balance maintenance unit (50) includes upper and lower horizontal axes (51, 52) whose ends are fixedly installed on the vertical frame (13) of the back bracket (10) so as to be positioned at a certain distance above and below the tilting axis (41), and may include upper and lower torsion springs (53, 54) respectively provided on the upper and lower horizontal axes.

[0086] The upper and lower torsion springs (53, 54) above may include a spring member having a coil-shaped body wound around the upper and lower horizontal axes (51, 52) and having both ends extending in opposite directions and connected by hooking.

[0087] It includes upper and lower guide axes (45) of a certain length, one end of which is inserted into and fixed to the fixing holes formed through the upper and lower portions of the above-mentioned rotating block (42), respectively, and the upper and lower guide axes are arranged to pass through upper and lower arc-shaped guide holes (43b) formed through the vertical frame of the above-mentioned back bracket and the fixing block (43) fixedly installed thereto, so that the upper and lower guide axes can move along the upper and lower arc-shaped guide holes in opposite directions with the tilting axis as the center when the above-mentioned rotating block is rotated.

[0088] Each end of the upper and lower torsion springs (53, 54) is connected by a hook so as to transmit elastic restoring force in opposite directions to the vertical frame of the back bracket (10), and each other end of the upper and lower torsion springs (53, 54) corresponding to the tilting guide (40) is connected by a hook so as to transmit elastic restoring force in opposite directions to each other end of the upper and lower guide shafts (45) exposed to the inside of the vertical frame, thereby elastically supporting the upper and lower parts of the rotating block in opposite directions with respect to the tilting shaft (41) as the center.

[0089] At this time, the vertical frame (13) of the back bracket (10) may include a fixed bracket (55) having a hooking groove or hooking hole in which each end of the upper and lower torsion springs (52, 54) provided on the upper and lower portions of the tilting axis are hooked in opposite directions.

[0090] In addition, each end of the upper and lower horizontal axes (51, 52) located on the vertical frame (13) of the back bracket (10) may include a contact member (45a) such as a bearing member or bushing member having a ring-shaped groove sunken into the outer surface where each end of the upper and lower torsion springs (53, 54) contacts.

[0091] The upper and lower torsion springs (53, 54) whose ends are connected in opposite directions to the back bracket (10) above elastically support the rotation block in opposite directions with respect to the tilting axis (41) as the center, thereby canceling out the external force, that is, the elastic force of the upper and lower torsion springs (53, 54) having the same elastic force, and thus limiting unnecessary rotation of the tilt-adjusted display device.

[0092] Accordingly, since the other ends of the upper and lower torsion springs are elastically brought into contact with the other ends of the upper and lower guide shafts that are arranged to be guided and movable in the upper and lower arc-shaped guide holes, the rotating blocks that rotate around the tilting axis are elastically supported in opposite directions, thereby generating a fixing force while the elastic force is offset, thereby preventing the tilt-adjusted inclined display device from sagging downward due to the self-weight moment, and stably maintaining the balance of the display device.

[0093] FIGS. 10a, 10b and 10c are perspective views illustrating an operating state in a tilting mode of a balance moving wall mount for a display device according to an embodiment of the present invention, and FIGS. 11(a), (b) and (c) are operating state diagrams illustrating a tilting mode of a balance moving wall mount for a display device according to an embodiment of the present invention, and FIGS. 12(a), (b) and (c) are schematic diagrams illustrating an operating state of an angle fixing part in a tilting mode of a balance moving wall mount for a display device according to an embodiment of the present invention.

[0094] As shown in Fig. 10b, Fig. 11(b) and Fig. 12(b), the back bracket (10) coupled with the display device and the wall bracket (20) fixedly installed on the wall are spread apart, and the first and second connecting plates of the connecting bracket (30) are spread apart, and the back bracket moves forward with respect to the wall bracket and is separated, and in this separation mode state, the user can perform a tilting mode to adjust the viewing angle by rotating the display device upward or downward.

[0095] That is, when a user holds the upper or lower edge of the display device and presses downward or lifts upward with an external force of a certain strength, the size of the external force of the user is greater than the size of the frictional force generated between the rotation block of the tilting guide and the fixed block, so that the rotation block (42) rotates clockwise or counterclockwise with respect to the fixed block (43) with the tilting axis (41) as the center of rotation, as shown in FIGS. 10a, 10c, 11(a), 11(c), 12(a), and 12(c), and in conjunction with this, the display device can be tilted upward or downward by a certain angle to adjust the viewing angle, thereby performing a tilting mode.

[0096] At this time, the display device tilted upward or downward at a certain angle and adjusted for tilting may sag downward due to its own weight moment, but the tilting adjustment state can be maintained by compensating for the own weight moment by the upper and lower torsion springs of the balance maintenance unit (50) provided adjacent to the tilting guide unit (40).

[0097] That is, since the elastic force of the upper and lower torsion springs provided in the balance maintenance unit (50) is set to be greater than the size of the frictional force generated between the rotation block and the fixed block in the tilt-adjusted state, the rotation block is elastically supported in opposite directions by the upper and lower torsion springs that come into contact with the other ends of the upper and lower guide axes arranged to be guided and movable in the upper and lower arc-shaped guide holes, thereby canceling out the self-weight moment of the display device and preventing the lower part of the display device, which is a heavy object, from sagging, and thereby stably maintaining the balance of the display device.

[0098] In succession, when the restraining pin passes through the vertical frame and the fixed block and is positioned within the restraining arc-shaped hole of the rotating block, the rotation of the rotating block can be restrained, so that the tilt-adjusted display device can be completely restricted and prevented from being tilted or rotated back unnecessarily due to unnecessary external force.

[0099] Figures 13 (a), (b), and (c) are operating state diagrams showing the swivel mode of a balance moving wall mount for a display device according to an embodiment of the present invention.

[0100] As shown in (a), (b) and (c) of Fig. 13, the display device can be rotated left and right in a swivel mode to adjust the viewing angle while the back bracket (10) combined with the display device and the wall bracket (20) fixedly installed on the wall are in a spaced apart mode.

[0101] That is, when a user holds one of the left and right edges of the display device and pushes or pulls it to the left or right with an external force of a certain strength, the first swivel axis (33) rotatably connecting the back bracket (10) and the first connecting plate (31), the second swivel axis (34) rotatably connecting the first connecting plate (31) and the second connecting plate (32), and the third swivel axis (35) rotatably connecting the second connecting plate (32) and the wall bracket (20) are centered, and the first and second connecting plates and the back bracket are independently rotated left and right with respect to the wall bracket, thereby tilting the display device left and right by a certain angle, thereby easily and freely adjusting the viewing angle in a swivel mode.

[0102] Figures 14 (a) and (b) are operation state diagrams showing the close-contact mode and the distance mode of the balance moving wall mount for a display device according to an embodiment of the present invention.

[0103] As shown in (a) of Fig. 14, the back bracket (10) and the wall bracket (20) are spaced apart from each other by a certain distance, and the user performs the close-fitting mode by pushing the display device toward the wall with a certain amount of external force.

[0104] That is, as shown in (b) of FIG. 14, when the display device is pushed toward the wall, the first and second connecting plates of the connecting bracket (30) connecting the back bracket (10) and the wall bracket (20) overlap, and at the same time, the overlapping first and second connecting plates and the wall bracket are arranged without interference inside the back bracket composed of the upper and lower horizontal frames (11, 12) and the vertical frame (13), so that the display device fixedly installed on the front of the back bracket can be brought close to the wall in a close-contact mode to prevent the rear exposure.

[0105] Conversely, when a user pulls the display device forward with a certain amount of external force while the back bracket (10) and the wall bracket (20) are in a close-fitting mode in which they overlap as shown in (b) of FIG. 14, the first and second connecting plates (31, 32) of the connecting bracket provided between the back bracket (10) and the wall bracket (20) are switched from a folded state to an unfolded state, so that the back bracket (10) and the wall bracket (20) can be switched to a separation mode in which the rear surface of the display device is exposed to the outside so that a cable can be connected, as shown in (a) of FIG. 14.

[0106] FIG. 15a and FIG. 15b are perspective views illustrating the exterior of a balance moving wall mount for a display device according to another embodiment of the present invention.

[0107] The back bracket (10) applied to the balance moving wall mount (100a) for a display device according to another embodiment of the present invention may include upper and lower expansion frames (14a, 14b) so as to expand the width size to both left and right sides, as shown in FIG. 15a.

[0108] The above upper and lower expansion frames (14a, 14b) can be detachably assembled and provided by a plurality of fastening members at each upper and lower end of a pair of vertical frames (13) connecting the two ends of the above upper and lower horizontal frames (11, 12).

[0109] Accordingly, when the size of the display device to be installed increases, a back bracket with wide keys extended on both the left and right sides can be fixedly installed on the back of the display device.

[0110] In addition, the back bracket (10) applied to the balance moving wall mount (100b) for a display device according to another embodiment of the present invention may include a central vertical frame (13a) in which the upper and lower ends are detachably connected by a plurality of fastening members in the middle of the length of the upper and lower horizontal frames (11, 12), as shown in FIG. 15b.

[0111] By providing a pair of tilting connection parts (40) in the middle of the length of each of the left and right sides of the central vertical frame (13a), a pair of first connection plates (31) provided on the connection bracket (30) can be connected to a pair of tilting guide parts (40), respectively.

[0112] Accordingly, if the size of the display device to be installed is small, the display device can be installed by fixing a back bracket having a central vertical frame to the back of the display device.

[0113] Project Name: Development of a commercialized back cover component for micro LED displays with thermal conductivity (100 W / m·K) achieved through casting process and surface treatment.

[0114] This application is the result of research on the "Gumi City Core Component Material Technology Development Project (R&D, G2023S02)" of Gumi City and Gumi Electronics and Information Technology Institute.
