Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2021-0193658, filed on December 31, 2021, which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to a gap adjustment member and a fixing device including the gap adjustment member. More specifically, this disclosure relates to a gap adjustment member capable of precisely and easily adjusting the gap between a wall and a display device, correcting the position of the display device, and stably fixing the display device, as well as a fixing device including the gap adjustment member. Background Technology

[0004] The technology for manufacturing displays has further developed, and recently, organic light-emitting displays and the like have become popular as high-end products.

[0005] In particular, organic light-emitting displays enable the realization of rollable displays, and due to their thinness and lightness, they are comparable to wall-mounted display devices.

[0006] In the high-end television (TV) market, large-area displays are often the preferred choice, and therefore, by combining multiple displays in a modular manner, large screens can be mounted on the wall to provide excellent display quality and immersion.

[0007] In this context, when installing a large-area display on a wall, the display should be securely fixed to the wall. Furthermore, when installing a display on a wall, it is required to install the display so that it is in contact with the wall as much as possible to minimize intrusion into the living space and improve image reproduction.

[0008] However, the conventional method for securing a monitor is to install a bracket on the wall surface and use various components to secure the back surface of the monitor, adjusting the gap accordingly. Workers must adjust the gap between the wall and the monitor by placing their hands in the space between them.

[0009] This conventional approach may have the following problems: workers bear a heavy workload, and the gap between the wall and the monitor may not be properly adjusted. In particular, when multiple monitors are arranged in a modular manner, level differences may exist between the monitors, leading to reduced user satisfaction. Furthermore, workers must readjust the monitors several times to fix the level differences. Therefore, calibration is difficult, and the workload for workers increases. Summary of the Invention

[0010] The purpose of this disclosure is to solve the aforementioned technical problems and to provide a gap adjustment member capable of precisely adjusting the gap between the wall and the display device, correcting the position of the installed display device, and stably fixing the display device, as well as a fixing device including the gap adjustment member.

[0011] In one embodiment, a gap adjustment member includes: a magnetic unit including a through hole configured to be attached to a bracket mounted on a wall; a helical beam disposed in the through hole of the magnetic unit; and an adjustment unit connected to the helical beam configured to move along the helical beam to adjust the gap between the wall and a display device to be connected to the adjustment unit.

[0012] In one embodiment, a fixing device includes: a bracket configured to be attached to a wall; a gap adjusting member configured to be attached to the bracket and adjust the gap between the wall and the display device; a fixing rod configured to connect to the gap adjusting member and the bracket, the fixing rod being configured to fix the position of the gap adjusting member in the bracket; and a joystick member configured to fix the fixing rod to the bracket.

[0013] In one embodiment, a gap adjustment member includes: a first magnetic end configured to be attached to a bracket mounted on a wall; a second end opposite to the first magnetic end configured to be attached to a display device; and an adjustment unit between the first magnetic end and the second end, at least a portion of the adjustment unit being configured to rotate to adjust the gap between the display device and the wall.

[0014] According to this disclosure, the gap between the wall and the display device can be adjusted precisely and easily.

[0015] In addition, the mounting position of the display device on the wall can be easily changed by attaching and removing the display device magnetically.

[0016] In addition, the display device can be stably fixed to the wall and can be easily disassembled. Attached Figure Description

[0050] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Unless there is contradiction, the various embodiments described below may be repeatedly applied.

[0051] Figures 1 to 7 A gap adjustment member 200 according to a first embodiment of the present disclosure is shown.

[0052] Reference Figures 1 to 7 The gap adjustment member 200 according to a first embodiment of this disclosure may include a magnetic unit 220 (e.g., a magnetic mechanism), a helical beam 210, an adjustment unit 300 (e.g., an adjustment mechanism), and a support block 250. In one embodiment, the term "unit" refers to a mechanical mechanism or structure configured to perform the functions described herein.

[0053] The magnetic unit 220 may include a through hole 220a into which a helical beam 210 (e.g., a fastener such as a screw) can be inserted, and the helical beam 210 may include a screwdriver slot 210a. Additionally, the adjustment unit 300 may include a link plate 315, a link beam 311, and an adjustment block 313 for Z-axis adjustment by rotation attached to the magnetic unit 220. Furthermore, the support block 250 may include an opening 250a.

[0054] Reference Figure 1 and Figure 2 The magnetic unit 220 (e.g., a magnet) may have a cylindrical shape, and a through-hole 220a may be formed in its central portion. The material of the magnetic unit 220 may be a permanent magnet, but is not necessarily limited to it. For example, when realizing a structure that allows for electrical adjustment of the magnetic force, the magnetic unit 220 may be an electromagnet.

[0055] 510 bracket (see) Figure 10 The support 510 can be mounted on the wall (W) where the display device (D) is installed, to fix (e.g., attach) the display device (D) to the wall, and the support 510 can be made of a material that responds to magnetic forces (including metallic materials such as iron, aluminum, etc.). The magnetic unit 220 can be attached to the support 510. Since this is a detachable method utilizing magnetic forces, the arrangement position of the display device can be easily changed. In addition, recently released display devices such as OLEDs are lightweight and can be attached using only magnetic forces.

[0056] Reference Figure 1 and Figure 2 The helical beam 210 can be installed while being inserted into the through hole 220a. A screwdriver slot 210a can be formed at the rear end of the helical beam 210, and a screw 210b (e.g., a threaded portion) can be formed at the front end of the helical beam 210. The screwdriver slot 210a can be Phillips head, straight, or hexagonal, and the shape can be determined according to the type of working screwdriver used to drive the helical beam 210. The operator inserts a working screwdriver into the screwdriver slot 210a and rotates the working screwdriver to fasten the helical beam 210 to the adjusting block 313 of the adjusting unit 300, as described below.

[0057] Reference Figure 1 , Figure 3 and Figure 4 When the adjustment unit 300 is connected to the spiral beam 210 and the display device (D) and moves along the spiral beam 210, the adjustment unit 300 can adjust the gap (L) between the wall (W) and the display device (D) (see...). Figure 4 ).

[0058] The adjustment unit 300 may include a connecting plate 315, a connecting beam 311, and an adjustment block 313.

[0059] The link plate 315 can be a material that responds to magnetic force (including metallic materials such as iron and aluminum), and can be the part to which the magnetic unit 220 is attached. In addition, the link plate 315 can have a shape that corresponds to (e.g., matches) the shape of the magnetic unit 220, and in embodiments of this disclosure it can have a circular plate shape, but is not limited thereto.

[0060] Link beam 311 can be in the form of a long cylindrical beam (e.g., a rod), and as... Figure 4 As shown, it can be connected to the display device (D) via the support block 250.

[0061] A support block 250 can be disposed on the display device (D) and can form an opening 250a through which the link beam 311 passes. Therefore, the link beam 311 can pass through the opening 250a and be inserted into the display device (D) to attach the link beam 311 to the display device (D). Although not shown in the figures, a fastening structure capable of connecting the link beam 311 to the display device (D) can be provided inside the display device (D).

[0062] Additionally, the support block 250 can be used to support the rotation of the connecting beam 311. When the opening 250a supports the connecting beam 311 and the connecting beam 311 rotates together with the adjusting block 313, the connecting beam 311 can rotate stably while being supported.

[0063] Next, the adjusting block 313 (e.g., a nut) can be a component that an operator rotates using a working tool such as a wrench or pliers. The outer periphery of the adjusting block 313 can be configured in a polygonal rod shape such that it can be rotated by insertion into a working tool. In embodiments of this disclosure, such as Figure 3 As shown, the outer periphery of the adjusting block 313 may have a quadrilateral rod shape in which flat surfaces 313a (e.g., flat side surfaces) are formed at 90-degree intervals, but is not limited thereto, and may be changed according to the shape of the working tool.

[0064] Furthermore, one side of the connecting plate 315 can be connected to one side of the adjusting block 313, and the other side (e.g., the end) of the connecting beam 311 can be connected to the magnetic unit 220 via the connecting plate 315 and the adjusting block 313. The adjusting block 313 and the connecting beam 311 can be made of the same material as the connecting plate 315.

[0065] Figure 5 A cross-sectional view of the gap adjustment member 200 taken along the AA section according to the first embodiment of the present disclosure is shown.

[0066] Reference Figure 5 A washer groove 314b can be formed inside the connecting plate 315. A washer 230 (e.g., a locking washer) can be provided in the washer groove 314b, and the washer 230 can generate tension in the helical beam 210 by applying a thrust between the magnetic unit 220 and the connecting plate 315 with elastic force. Therefore, the helical beam 210 will not be accidentally loosened.

[0067] Furthermore, a threaded groove 314a may be formed inside the adjusting block 313, and a screw 210b formed on the outer peripheral surface of the spiral beam 210 may be fastened to the threaded groove 314a.

[0068] In this configuration, when the operator uses a tool (e.g., a wrench) to rotate the adjusting block 313, the connecting beam 311 and the connecting plate 315 rotate together.

[0069] At this time, the connecting beam 311 is supported and rotated by the support block 250, and as the connecting plate 315 rotates, the threaded groove 314a and the helical beam 210 loosen or tighten with each other.

[0070] The spiral beam 210 is fixed and does not rotate when inserted into the through hole of the magnetic unit 220 due to the tension generated by the washer 230.

[0071] Therefore, when the adjusting block 313 rotates, the threaded groove 314a loosens or tightens the screw 210b along the helical beam 210. In this way, the gap (L) between the display device (D) and the wall (W) is adjusted. That is, the gap between the display device (D) and the wall (W) is adjusted in the Z direction (see...). Figure 4 ).

[0072] Next, Figure 6 A cross-sectional view of another form of the gap adjustment member 200 taken along the AA section according to the first embodiment of the present disclosure is shown.

[0073] Reference Figure 6 The threaded groove 314a formed inside the adjusting block 313 and the screw 210b formed on the outer peripheral surface of the spiral beam 210 can be fastened to each other.

[0074] Figure 6 The shape ratio of the threaded groove 314a and the helical beam 210 shown is... Figure 5 The shape shown is long. (Refer to...) Figure 6 The helical beam 210 can be inserted into the connecting beam 311 of the adjustment unit 300. The threaded groove 314a formed inside the connecting beam 311 and the screw 210b formed on the outer peripheral surface of the helical beam 210 can be fastened to each other.

[0075] In this structure, when the operator uses a tool to rotate the adjusting block 313, the range of loosening or tightening of the threaded groove 314a and the helical beam 210 relative to each other is greatly increased. That is, the range of adjustable clearance (L) between the display device (D) and the wall (W) is increased.

[0076] With the above structure, the gap adjustment member 200 according to the first embodiment of the present disclosure can easily and accurately adjust the gap (L) between the wall (W) and the display device (D).

[0077] Figure 7 This is an exploded perspective view of the gap adjustment component according to the contents of this disclosure.

[0078] Reference Figure 7 The magnetic unit 220, helical beam 210, adjustment unit 300, and support block 250 described above are combined to form a gap adjustment member 200 according to the present disclosure. The magnetic unit 220 may include a through hole 220a into which the helical beam 210 can be inserted, and the helical beam 210 may include a screwdriver slot 210a. Additionally, the adjustment unit 300 may include a link plate 315, a link beam 311, and an adjustment block 313 for Z-axis adjustment by rotation attached to the magnetic unit 220. Furthermore, the support block 250 may include an opening 250a. The helical beam 210 may be provided while being inserted into the through hole 220a. The screwdriver slot 210a may be formed at the rear end of the helical beam 210, and a screw 210b may be formed at the front end of the helical beam 210. The screwdriver slot 210a may have a cross shape, a straight shape, or a hexagonal shape, etc., and the shape may be determined according to the type of screwdriver used. The operator inserts a working screwdriver into the screwdriver slot 210a and rotates the working screwdriver to fasten the spiral beam 210 to the adjustment block 313 of the adjustment unit 300, which will be reviewed below.

[0079] exist Figures 11 to 1 Figure 5 shows a gap adjustment member 200 according to a second embodiment of the present disclosure.

[0080] Reference Figures 11 to 13The gap adjustment member 200 according to the second embodiment of the present disclosure may include a magnetic unit 220, a helical beam 210, an adjustment unit 300, and a nut 260 (e.g., a fastener).

[0081] The magnetic unit 220 may include a through hole 220a, and the helical beam 210 may include a screwdriver slot 210a and a screw 210b. Furthermore, the adjustment unit 300 may include a housing 325, a cover 327, an elastomer 328, and a guide cam 321. Additionally, the housing 325 may include an opening 325a and a beam hole 325b, and the cover 327 may include a protrusion 327a and an insertion portion 327b.

[0082] The magnetic unit 220 may have a cylindrical shape, and a through hole 220a may be formed in the central portion. The material of the magnetic unit 220 may be a permanent magnet, but is not necessarily limited to this. For example, when realizing a structure that allows for electrical adjustment of the magnetic force, the magnetic unit 220 may be an electromagnet.

[0083] The bracket 510 can be mounted on the wall (W) where the display device (D) is installed to fix the display device (D), and the bracket 510 can be made of a material that responds to magnetic force (including metal materials such as iron and aluminum). The magnetic unit 220 can be attached to the bracket 510. Since this is a detachable method utilizing magnetic force, the arrangement position of the display device can be easily changed.

[0084] The helical beam 210 can be simultaneously inserted into the through hole 220a of the magnetic unit 220. A screwdriver slot 210a can be formed at the rear end of the helical beam 210, and a screw 210b can be formed around the outer periphery of the helical beam 210. The screwdriver slot 210a can have a cross shape, a straight shape, or a hexagonal shape, etc., and the shape can be determined according to the type of working screwdriver. The operator inserts a working screwdriver into the screwdriver slot 210a and rotates the working screwdriver to fasten the helical beam 210 to the guide cam 321 of the adjustment unit 300, which will be reviewed below.

[0085] The rear end of the helical beam 210 is inserted into a through hole 220a formed on the rear end surface of the magnetic unit 220, and a nut 260 is provided on the front end surface of the magnetic unit 220. The helical beam 210 and the magnetic unit 220 can be connected together by fastening the nut 260 to the helical beam 210.

[0086] The adjustment unit 300 is connected to the spiral beam 210 and the display device (D) and moves along the spiral beam 210 to adjust the gap between the wall (W) and the display device (D).

[0087] The adjustment unit 300 may include a housing 325, a cover 327, an elastomer 328, and a guide cam 321.

[0088] The housing 325 may have a cylindrical shape in which a space is formed, a beam hole 325b through which the helical beam 210 passes is formed at one end of the housing 325, and an opening 325a larger than the beam hole 325b is formed at the other end of the housing 325.

[0089] An insertion portion 327b is formed at one end of the cover 327, coupled to an opening 325a in the housing 325, and can seal the housing 325. A protrusion 327a may be formed at the other end of the cover 327 for connection to a display device (D). Although not shown in the figures, a structure for connecting the protrusion 327a of the cover 327 to the display device (D) may be provided in the display device (D). A receiving space 327c may be formed in the cover 327 to accommodate a portion of an elastomer 328 (e.g., a spring).

[0090] The guide cam 321 may be disposed inside the housing 325. Furthermore, the guide cam 321 may include a body 321c, a helical groove 321a formed at one end of the guide cam 321 and connected to the helical beam 210, and a thread 321b formed on the inner circumferential surface of the helical groove 321a. The thread 321b of the guide cam 321 and the screw 210b of the helical beam 210 can engage and be fastened. Additionally, the guide cam 321 may also include a receiving groove 324 formed at the other end of the guide cam 321. A portion of the elastomer 328 may be accommodated in the receiving groove 324.

[0091] The elastomer 328 can be disposed inside the housing 325, located between the receiving groove 324 of the guide cam 321 and the receiving space 327c of the cover 327. The elastomer 328 is located on the guide cam 321 along the first direction (Z1) (see...). Figure 14A ) is compressed during movement, and can guide cam 321 along the second direction (Z2) (see Figure 14A Movement provides resilience.

[0092] like Figures 12 to 1 As shown in Figure 4, in the second embodiment of this disclosure, the adjustment unit 300 may further include a guide pin 326, a guide line 330, a first end groove 341, and a second end groove 346.

[0093] The guide pin 326 may be configured to protrude from inside the housing 325. In embodiments of this disclosure, the guide pin 326 may have a cylindrical shape to facilitate smooth movement of the guide line 330. However, this disclosure is not necessarily limited to this.

[0094] Guide lines 330 may be formed on the outer periphery of guide cam 321, and guide pins 326 may be inserted into guide cam 321. Here, guide lines 330 may include a first guide line 331 and a second guide line 336. The guide lines may be channels formed in guide cam 321 that control the direction of movement of guide cam 321.

[0095] When the guide cam 321 rotates, the first guide line 331 moves along the guide pin 326, and then the first guide line 331 can cause the guide cam 321 to advance in a first direction (Z1) along the compression elastomer 328. The first guide line 331 can bend from the first direction (Z1) to a second direction (Z2).

[0096] When the guide cam 321 rotates, the second guide line 336 can move along the guide pin 326, causing the guide cam 321 to move backward in a second direction (Z2) that extends the elastic body 328. The second guide line 336 can bend from the second direction (Z2) to the first direction (Z1).

[0097] In this case, the first guide line 331 and the second guide line 336 can be connected to each other and can be alternately arranged along the outer periphery of the guide cam 321.

[0098] Next, refer to Figure 14A and 15A The first end groove 341 can be configured to be adjacent to the first surface (F1) of the guide cam 321. Furthermore, the first end groove 341 can be configured to connect the end of the first guide line 331 (e.g., the first end) and the end of the second guide line 336 (e.g., the second end), and can be formed to extend along a first direction (Z1).

[0099] Here, 1-1 (e.g., first) groove surface portion 342 and 1-2 (e.g., second) groove surface portion 343 can be formed on the first side and the second side of the first end groove 341, respectively. 1-1 groove surface portion 342 can be connected to the end of the first guide line 331, and 1-2 groove surface portion 343 can be connected to the end of the second guide line 336.

[0100] In this case, the length (G1) of the 1-1 groove surface portion 342 and the length (G2) of the 1-2 groove surface portion 343 can be different from each other. In embodiments of this disclosure, the length (G1) of the 1-1 groove surface portion 342 can be formed to be longer than the length (G2) of the 1-2 groove surface portion 343.

[0101] The reason why the length (G1) of the 1-1 groove surface portion 342 is longer than the length (G2) of the 1-2 groove surface portion 343 is that the guide pin 326, which moves along the second guide line 336, impacts the groove surface portion 342, thereby causing the guide pin 326 to move into the first end groove 341.

[0102] Since the length (G1) of the surface portion 342 of the 1-1 groove is longer than the length (G2) of the surface portion 343 of the 1-2 groove, the guide pin 326 can be guided into the first end groove 341 without moving to the first guide line 331 connected to the second guide line 336.

[0103] Meanwhile, the first boundary portion 332, in which the end of the second guide line 336 and the end of the first guide line 331 contact each other, can be provided on the guide cam 321.

[0104] When the guide cam 321 rotates, the first boundary portion 332 can be positioned collinear with the first extension line (P1) passing through the 1-2 groove surface portion 343 (e.g., extending from the 1-2 groove surface portion 343), or it can be positioned more toward the direction of rotation relative to the first extension line P1 (see arrow K indicating the direction of rotation) to prevent the guide pin 326 from moving back to the second guide line 336.

[0105] In addition, in order to move the guide pin 326, which moves toward the inside of the first end groove 341 when the guide cam 321 rotates, toward the first guide line 331, the second extension line (P2) passing through the center line of the first end groove can be formed to be more toward the opposite direction of rotation of the guide cam than the first extension line (P1).

[0106] Because the first boundary portion 332 is positioned more towards the direction of rotation relative to the first extension line (P1), and the second extension line (P2) is formed more towards the opposite direction of rotation relative to the first extension line (P1), when the guide cam 321 rotates continuously, the guide pin 326, which moves along the first guide line 331 and then towards the inside of the second end groove 346, can be immediately introduced into the second guide line 336, while backward movement towards the first guide line 331 is prevented. The specific operating principle will be described below.

[0107] Next, the second end groove 346 can be configured to be adjacent to the second surface (F2) of the guide cam 321. Furthermore, the second end groove 346 can be configured to connect the end of the first guide line 331 (e.g., the second end) and the end of the second guide line 336 (e.g., the second end), and can be formed to extend along the second direction (Z2).

[0108] Here, the 2-1 groove surface portion 347 and the 2-2 groove surface portion 348 can be formed on both sides of the second end groove 346, and the 2-1 groove surface portion 347 can be connected to the end of the first guide line 331, and the 2-2 groove surface portion 348 can be connected to the end of the second guide line 336.

[0109] In this case, the length (G3) of the 2-1 groove surface portion 347 and the length (G4) of the 2-2 groove surface portion 348 can be different from each other. In embodiments of this disclosure, the length (G4) of the 2-2 groove surface portion 348 can be formed to be longer than the length (G3) of the 2-1 groove surface portion 347.

[0110] The reason why the length (G4) of the 2-2 groove surface portion 348 is longer than the length (G3) of the 2-1 groove surface portion 347 is: so that the guide pin 326 moving along the first guide line 331 hits the 2-2 groove surface portion 348, thereby moving the guide pin 326 into the second end groove 346.

[0111] Since the length (G4) of the surface portion 348 of the 2-2 groove is longer than the length (G3) of the surface portion 347 of the 2-1 groove, the guide pin 326 can be immediately introduced into the second end groove 346 without moving to the second guide line 336 connected to the first guide line 331.

[0112] Meanwhile, a second boundary portion 333 may be provided in the guide cam 321, in which the end of the second guide line 336 and the end of the first guide line 331 are in contact with each other.

[0113] To prevent the guide pin 326, which moves toward the inside of the second end slot 346, from moving backward toward the first guide line 331 when the guide cam 321 rotates, the second boundary portion 333 can be configured to be collinear with the third extension line (P3) passing through the surface portion 347 of the 2-1 slot, or it can be configured to be more toward the direction of rotation relative to the third extension line (P3) (see arrow K indicating the direction of rotation).

[0114] Furthermore, in order to move the guide pin 326, which moves toward the inside of the second end groove when the guide cam 321 rotates, toward the second guide line 336, the fourth extension line (P4) passing through the center line of the second end groove 346 can be formed to be more toward the opposite direction of rotation of the guide cam 321 than the third extension line (P3).

[0115] Because the second boundary portion 333 is positioned more towards the direction of rotation than the aforementioned third extension line (P3), and the fourth extension line (P4) is positioned more towards the opposite direction of rotation than the third extension line (P3), when the guide cam 321 rotates continuously, the guide pin 326, which moves along the first guide line 331 and then towards the interior of the second end groove 346, is immediately introduced into the second guide line 336, while backward movement towards the first guide line 331 is prevented. The specific operating principle will be described below.

[0116] Due to the structure of the first end groove 341 and the second end groove 346, when the guide cam 321 rotates, the guide pin 326 can make the first guide line 331 and the second guide line 336 move sequentially, and the guide cam 321 can move along the first direction (Z1) or the second direction (Z2).

[0117] on the other hand, Figures 14A to 14C This illustrates an operation method for adjusting the gap between the wall (W) and the display device (D) by applying the gap adjustment member 200. Additionally, Figures 15A to 15A The diagram illustrates the movement structure of the guide cam 321 and guide pin 326 when the gap between the wall (W) and the display device (D) is increased by applying the gap adjustment member 200.

[0118] Figures 14A to 15A The rotation direction of the guide cam 321 disclosed herein can be the direction that increases the gap between the wall (W) and the display device (D).

[0119] First, such as Figure 14A As shown, the gap between the display device (D) and the wall (W) is designated as the E0 gap, and the description will adjust it to be as follows. Figure 14C The operation process of the E1 gap is shown.

[0120] Reference Figure 14A and Figure 15A The guide pin 326 is located in the first end groove 341.

[0121] like Figure 14B As shown, in order to adjust the gap between the display device (D) and the wall (W), the operator can perform a simple operation of pushing the display device (D) along the direction of the wall (W).

[0122] When the operator pushes the display device (D) in the direction of the wall (W) as indicated by arrow (S1), the housing 325 and cover 327 are pushed in the direction of the wall (W), while the guide cam 321 is connected to the spiral beam 210.

[0123] Guide pin 326 is disposed inside housing 325 and located in first end groove 341, and when housing 325 and cover 327 are pushed along the wall (W) direction, guide pin 326 exits first end groove 341 and moves along first guide line 331. Furthermore, as in Figure 14B and Figure 15B In the middle, the guide pin 326 moves into the second end groove 346.

[0124] In fact, since the position of the guide pin 326 inside the housing 325 is fixed, the guide cam 321 rotates along the screw 210b of the helical beam 210, and thus rotates in the direction of arrow (K) around the first guide line 331 and the second end groove 346 formed around the outer periphery of the guide cam 321.

[0125] At this time, the elastomer 328 is in a compressed state and provides a restoring force, causing the housing 325 and the cover 327 to move again along the first direction (Z1).

[0126] Next, refer to Figure 14C and Figure 15C The elastomer 328 provides a restoring force to the housing 325 and the cover 327, and the housing 325 and the cover move in the first direction (Z1), and thus the display device (D) moves in the direction of the arrow (S2).

[0127] The guide cam 321 rotates along the screw 210b of the helical beam 210 in the direction of arrow (K), and the guide pin 326 exits the second end slot 346 and moves along the second guide line 336. Then, the guide pin 326 is located in the first end slot 341 of the next sequence.

[0128] When the guide cam 321 rotates in the direction of arrow (K), the degree of winding between the guide cam 321 and the spiral beam 210 changes, and the gap between the display device (D) and the wall (W) is adjusted by the changing length.

[0129] Finally, the gap between the display device (D) and the wall (W) is from Figure 14A The E0 gap shown is adjusted to... Figure 14C The E1 gap is shown.

[0130] The operator can easily adjust the gap between the display device (D) and the wall (W) by repeating the operation several times.

[0131] Here, by adjusting the total number of times the first guide line 331 and the second guide line 336 are connected to each other and alternately arranged around the outer periphery of the guide cam 321, the clearance of the spiral groove moving along the spiral beam 210 can be precisely controlled.

[0132] For example, in an embodiment of this disclosure, the first guide line 331 and the second guide line 336 are connected to each other around the outer periphery of the guide cam 321 and are arranged alternately three times, i.e., three sets. The gap can be adjusted more precisely if the spacing between the two guide lines 331 and 336 is changed to six sets.

[0133] at the same time, Figures 16A to 16C The diagram illustrates the movement structure of the guide cam 321 and guide pin 326 when the gap between the wall (W) and the display device (D) is reduced by applying the gap adjustment member 200.

[0134] Figures 16A to 16C The rotation direction of the guide cam 321 disclosed herein can be the direction that reduces the gap between the wall (W) and the display device (D).

[0135] Figures 16A to 16C The first guide line 331 and the second guide line 336 formed in the guide cam 321 shown are formed as follows: Figures 15A to 15C The first guide line 331 and the second guide line 336 formed in the guide cam 321 shown are in opposite directions.

[0136] As mentioned above, Figures 15A to 15C The rotation direction of the guide cam 321 disclosed herein is the direction that increases the gap between the wall (W) and the display device (D), and therefore Figures 16A to 16C The rotation direction of the guide cam 321 disclosed in the paper is the direction that reduces the gap between the wall (W) and the display device (D).

[0137] To view the operation instructions, first refer to... Figure 16A The guide pin 326 is located in the first end groove 341.

[0138] To adjust the gap between the display device (D) and the wall (W), the operator can perform a simple operation by pushing the display device (D) along the direction of the wall (W).

[0139] When the operator pushes the display device (D) along the wall (W), the housing 325 and cover 327 are pushed along the wall (W), while the guide cam 321 is connected to the spiral beam 210.

[0140] Guide pin 326 is disposed inside housing 325 and located in first end groove 341, and when housing 325 and cover 327 are pushed along the wall (W) direction, guide pin 326 exits from inside first end groove 341 and moves along first guide line 331. Figure 16B As shown, the guide pin 326 moves into the second end slot 346.

[0141] In fact, since the position of the guide pin 326 inside the housing 325 is fixed, the guide cam 321 rotates along the screw 210b of the helical beam 210, and thus rotates in the direction of arrow (K) around the second end groove 346 and the first guide line 331 formed around the outer periphery of the guide cam 321.

[0142] At this point, the elastomer 328 is under compression and provides a restoring force, causing the housing 325 and the cover 327 to move back along the first direction (Z1) (see...). Figure 14A )move.

[0143] Next, refer to Figure 16C When the elastomer 328 provides a restoring force to the housing 325 and the cover 327, the housing 325 and the cover 327 move along the first direction (Z1) (see...). Figure 14A The device moves, and therefore the display device (D) moves in the direction indicated by the arrow (S2).

[0144] The guide cam 321 rotates along the screw 210b of the helical beam 210 in the direction of arrow (K), and at this time, the guide pin 326 exits the second end slot 346 and moves along the second guide line 336. Then, the guide pin 326 is located in the first end slot 341 of the next sequence.

[0145] When the guide cam 321 rotates in the direction of arrow (K), the degree of winding between the guide cam 321 and the spiral beam 210 changes, and the gap between the display device (D) and the wall (W) is adjusted by the changing length.

[0146] The operator can easily adjust the gap between the display device (D) and the wall (W) by repeating the operation several times.

[0147] on the other hand, Figures 8 to 10 The paper discloses a fixing device 100 that applies the gap adjustment member 200 of the first embodiment, and... Figure 17A , Figure 17B and Figure 18 The image shows a fixing device 100 that applies the gap adjustment member 200 of the second embodiment.

[0148] also, Figures 19A to 19D The method of operation of the fixing device 100 according to the present disclosure is shown.

[0149] Before describing, because Figures 8 to 10 The fixing device 100 shown and Figure 17A , Figure 17B , Figure 18 as well as Figures 19A to 19DSince the fixing device 100 shown is the same, the description of the fixing device 100 using the gap adjustment member 200 of the second embodiment is also applicable to the fixing device 100 using the gap adjustment member 200 of the first embodiment.

[0150] Therefore, in the following text, it will be described Figure 17A , Figure 17B , Figure 18 as well as Figures 19A to 19D It can be related to... Figures 8 to 10 The same method as described is applied.

[0151] Reference Figure 17A , Figure 17B and 18 The fixing device 100 according to this disclosure may include a bracket 510, a clearance adjustment member 200, a fixing rod 520, and a lever member 530.

[0152] The bracket 510 can be bolted to the wall (W) and can be made of a material that responds to magnetic force (including metallic materials such as iron and aluminum). The bracket 510 may include a mounting plate 513, a top flange 511, and a bottom flange 512.

[0153] Multiple fastening holes 513a may be formed on the mounting plate 513, and fasteners such as bolts and nails may be coupled to the fastening holes 513a to be fixed to the wall (W).

[0154] The top flange 511 may have a plate shape and may be configured to connect to the top end of the mounting plate 513, and the bottom flange 512 may have a plate shape and may be configured to connect to the bottom end of the mounting plate 513. Here, the top flange 511 and the bottom flange 512 may be configured to be parallel to each other.

[0155] The gap adjustment member 200 is attached to the bracket 510 and can adjust the gap between the wall (W) and the display device (D). As described above, the gap adjustment member 200 includes a magnetic unit 220, and the magnetic unit 220 can be attached to the bracket 510.

[0156] For the method of adjusting the gap between the gap adjustment member 200 and the display device (D), refer to the description above.

[0157] The fixing rod 520 can be connected to the gap adjustment member 200 and coupled to the bracket 510 to fix the position of the gap adjustment member 200 to the bracket 510. Additionally, the fixing rod 520, coupled to the bracket 510, can also additionally support the display device in addition to the magnetic unit 220. The fixing rod 520 may include a body plate 521, a first plate 523, and a second plate 527.

[0158] The body plate 521 may have a curved U-shape on both sides and may form a first insertion groove 525 through which the gap adjustment member 200 passes.

[0159] The first plate 523 can be connected to the top of the body plate 521 by tilting at a first angle (θ1). (Refer to...) Figure 19A and Figure 19B The first angle (θ1) can be the angle at which the first plate 523 contacts and is parallel to the top flange 511 when the body plate 521 rotates. In addition, a second insertion groove 526 can be formed in the first plate 523 into which the protruding pin 535 of the lever member 530 is inserted.

[0160] The second plate 527 can be connected to the lower end of the main plate 521 by tilting at a second angle (θ2). (Refer to...) Figure 19A and Figure 19B The second angle (θ2) can be the angle at which the second plate 527 contacts the bottom flange 512 and is placed parallel when the main plate 521 rotates.

[0161] If the top flange 511 and the bottom flange 512 are parallel to each other, the first angle (θ1) and the second angle (θ2) can be θ1 = 180° - θ2. In this case, when the fixing rod 520 rotates, the first support plate 523 and the second support plate 527 can be respectively placed on the top flange 511 and the bottom flange 512.

[0162] Therefore, as Figure 19A and Figure 19B As shown, when the body plate 521 rotates, the first plate 523 is mounted on the top flange 511 and fixed by the control lever member 530, and the second plate 527 can be mounted on the bottom flange 512.

[0163] As described above, when the fixing rod 520 is mounted on the top flange 511 and the bottom flange 512, the display device (D) connected to the gap adjustment member 200 can be supported. That is, the display device (D) can be prevented from falling down due to the weight of the display device (D).

[0164] Furthermore, since an upwardly curved extension 512a is formed at the end of the bottom flange 512, when the second plate 527 is placed on the inner bottom surface of the bottom flange 512, the second plate 527 is supported by the mounting plate 513 and the extension 512a of the bottom flange 512, thereby preventing deviation in the Z direction.

[0165] Next, the joystick assembly 530 can secure the fixed rod 520 to the bracket 510. The joystick assembly 530 may include a protruding pin 535 and a joystick handle 531.

[0166] A protruding pin 535 is provided on the top flange 511, and a pin groove 535a may be formed on one side thereon. In addition, when the first plate 523 is placed on the top flange 511, the protruding pin 535 may be configured to pass through the first insertion groove 525.

[0167] The joystick handle 531 can be connected to the pin slot 535a and the joystick pin 533.

[0168] like Figure 19C and Figure 19D As shown, when the operator holds and rotates the joystick handle 531, the first plate 523 can be pressed and secured to the top flange 511.

[0169] The operating principle of the joystick component 530 can be similar to that of the QR joystick (quick-release joystick), but is not limited thereto.

[0170] The structure of the fixing device 100 according to this disclosure is the same as described above, and will be referred to below. Figures 19A to 19D To describe the operation method of the fixing device 100.

[0171] Reference Figure 19A The magnetic unit 220 of the gap adjustment member 200 connected to the display device (D) is attached to the mounting plate 513 of the bracket 510 to fix the installation position of the display device (D).

[0172] To prevent the position of the clearance adjustment member 200 on the mounting plate 513 from changing, it is necessary to fix the attachment position of the clearance adjustment member 200. Therefore, the fixing rod 520 is coupled to the clearance adjustment member 200.

[0173] The first insertion slot 525 is formed in the body plate 521 of the fixing rod 520, and the gap adjustment member 200 is coupled to the first insertion slot 525.

[0174] In the gap adjustment member 200 of the first embodiment, the connecting beam 311 can be configured to pass through the first insertion slot 525.

[0175] Furthermore, in the gap adjustment member 200 of the second embodiment, the helical beam 210 is configured to pass through the first insertion slot 525.

[0176] The operator lowers the fixing rod 520 downward from the upper part of the gap adjusting member 200, so that the gap adjusting member 200 is coupled to the insertion slot.

[0177] Next, refer to Figure 19BThe operator rotates the fixing rod 520 so that the first plate 523 of the fixing rod 520 is placed on the top flange 511 of the bracket 510. At this time, the second plate 527 of the fixing rod 520 is placed on the bottom flange 512 of the bracket 510.

[0178] At this time, the first insertion slot 525 also rotates, and the gap adjustment member 200 coupled to the first insertion slot 525 is restricted from moving up, down, left or right.

[0179] Reference Figure 10 and Figure 18 Four brackets 510 are configured to fix a display device (D) to the wall (W), and two fixing rods 520 are respectively mounted on the two upper brackets 510. The lower bracket has no fixing rods 520.

[0180] At this time, since the two first insertion slots 525 formed on the two fixed rods 520 are arranged in opposite inclined directions, the gap adjustment member 200 coupled to the two first insertion slots 525 will not move in the up-down (X-axis) and left-right (Y-axis) directions. That is to say, since the attachment position of the gap adjustment member 200 is fixed, the position of the display device (D) connected to the gap adjustment member 200 is also fixed.

[0181] Next, refer to Figure 19C The operator couples the joystick component 530 to secure the fixed rod 520 to the bracket 510.

[0182] As described above, the protruding pin 535 is mounted on the top flange 511, and when the retaining rod 520 is lowered, the protruding pin 535 is positioned to pass through the second insertion slot 526. (Refer to...) Figure 9 and Figure 17B As can be seen, the protruding pin 535 is configured to pass through the second insertion slot 526.

[0183] The operator connects the joystick handle 531 to the protruding pin 535, and at this time, since the joystick pin 533 is connected to the joystick handle 531, the operator inserts the joystick pin 533 into the pin groove 535a. Then, the operator grips the joystick handle 531 and rotates it.

[0184] Next, refer to Figure 19D The control lever handle 531 is lowered, and the first plate 523 of the fixing lever 520 is pressed against the top flange 511 and fixed.

[0185] Finally, the first plate 523 is placed on the top flange 511, the second plate 527 is placed on the bottom flange 512, and the mounting position of the gap adjustment member 200 is fixed inside the first insertion slot 525. Therefore, the display device (D) can not only be easily and simply mounted on the wall (W), but also be stably connected to the wall (W).

[0186] at the same time, Figure 20A This is a view showing the state in which the fixing device, according to another embodiment of the present disclosure, is coupled to the display device, and Figure 20B This is a view illustrating a fixing device according to another embodiment of the present disclosure.

[0187] Reference Figure 20A and Figure 20B According to another embodiment of the present disclosure, the fixing device 100 may include a first bracket 611, a second bracket 616, a first spherical joint unit 634, a second spherical joint unit 639, and a gas damper 650.

[0188] The first bracket 611 can be fixed to the wall to which the display device (D) is to be attached by bolts. The first support block 612 can be disposed on one side of the first bracket 611, and the first ball joint unit 634 can be disposed on the first support block 612.

[0189] The first spherical connector unit 634 may include a first spherical housing 632 disposed on the first support block 612 and a first ball 631 disposed inside the first spherical housing 632. In order to increase the friction of the first ball 631 to fix the position of the fixing device 100, a first seal 633 may be arranged around the outer periphery of the first ball 631. The first seal 633 forms frictional resistance with the inner surface of the first spherical housing 632, thereby preventing the display device (D) from being released from the fixed position.

[0190] Next, the second bracket 616 can be fixed to the display device (D) by bolts. The second support block 617 can be disposed on one side of the second bracket 616, and the second ball joint unit 639 can be disposed inside the second support block 617.

[0191] The second spherical connector unit 639 may include a second spherical housing 638 disposed inside the second support block 617 and a second ball 636 disposed inside the second spherical housing 638. In order to increase the friction of the second ball 636 to fix the position of the fixing device 100, a second seal 637 may be arranged around the outer periphery of the second ball 636. The second seal 637 forms frictional resistance with the inner surface of the second spherical housing 638, thereby preventing the display device (D) from being released from its fixed position.

[0192] Additionally, the gas damper 650 can be connected to the first spherical connector unit 634 and the second spherical connector unit 639. The gas damper 650 may include a first rod 652 coupled to the first ball 631, a second rod 653 coupled to the second ball 636, and a gas spring damper cylinder 651 that expands and contracts the first rod 652 and the second rod 653, respectively.

[0193] According to the above configuration, the first spherical connector unit 634 and the second spherical connector unit 639 can fix the display device at the desired position in the X and Y axes by adjusting their positions several times. In addition, by adjusting the gap between the first spherical connector unit 634 and the second spherical connector unit 639, the gas damper 650 can adjust the gap between the wall surface and the display device in the Z axis direction.

[0194] at the same time, Figure 21A This is a view showing the state in which the fixing device 100, according to another embodiment of the present disclosure, is coupled to a display device, and Figure 21B yes Figure 21A A side view of the fixing device disclosed herein.

[0195] Reference Figure 21A and Figure 21B According to another embodiment of the present disclosure, the fixing device 100 may include a third bracket 710, a fourth bracket 760, a third ball joint unit 730, a fourth ball joint unit 740, and a fixing unit 720.

[0196] The third support 710 can be fixed to the wall by bolts. An L-shaped third support block is connected to one side of the third support 710 to form a receiving space, and a fixing unit 720 can be disposed inside the receiving space. The fixing space can be formed in the third support block, and the fixing unit 720 can be connected to the third ball joint unit 730 and the first connecting beam 725. Furthermore, the first connecting beam 725 can be inserted into the fixing space, and the fixing unit 720 can be disposed in the receiving space formed by the second support block 617 and the third support 710.

[0197] The third spherical joint unit 730 can be connected to the fixed unit 720 via the first connecting beam 725, and can be connected to the fourth spherical joint unit 740 via the second connecting beam 733.

[0198] The third spherical joint unit 730 may include a third spherical housing 731 connected to the third spherical joint unit 730 and the second connecting beam 733, and a third ball 735 disposed inside the third spherical housing 731. In this case, the third seal 736 may be arranged around the outer periphery of the third ball 735 to increase the friction of the third ball 735, thereby fixing the position of the fixing device.
