At least a part of the (<NUM>-<NUM>)-th link 80b2 may be accommodated in the second accommodating recess 81b of the (<NUM>-<NUM>)-th link 80b1. Accordingly, the overall thickness of the wall mount assembly <NUM> can be reduced in a state in which the (<NUM>-<NUM>)-th link 80b1 and the (<NUM>-<NUM>)-th link 80b2 are folded.

The (<NUM>-<NUM>)-th link 80b1 may be hinge-connected to the other end of the fixing part <NUM>. That is, the other end of the (<NUM>-<NUM>)-th link 80b1 may be rotatably coupled to one end of the fixing part <NUM>. For example, the other end of the (<NUM>-<NUM>)-th link 80b1 and the other end of the fixing part <NUM> may be provided in a shape to match each other in male and female forms and may be coupled to each other. Here, the (<NUM>-<NUM>)-th link 80b1 may be rotatably provided with respect to the fixing part <NUM> based on a virtual axis extending in the vertical direction and may be positioned in parallel to the fixing part <NUM> or may be positioned to have a predetermined angle with respect to the fixing part <NUM> in response to rotation. A friction member for providing a predetermined frictional force during rotation may be provided between fixing structures of the other end of the (<NUM>-<NUM>)-th link 80b1 and the other end of the fixing part <NUM>. Due to the friction member, the (<NUM>-<NUM>)-th link 80b1 may maintain the previous state thereof without rotating with respect to the fixing part <NUM> as long as the user does not provide a force equal to or greater than a preset level.

The (<NUM>-<NUM>)-th link 80b2 may be hinge-connected to the other end of the frame <NUM>. That is, the other end of the (<NUM>-<NUM>)-th link 80b2 may be rotatably coupled to the other end of the frame <NUM>. For example, the other end of the (<NUM>-<NUM>)-th link 80b2 and the other end of the frame <NUM> may be provided in a shape to match each other in male and female forms and may be coupled to each other. Here, the (<NUM>-<NUM>)-th link 80b2 may be rotatably provided with respect to the frame <NUM> based on a virtual axis extending in the vertical direction and may be positioned in parallel to the frame <NUM> or may be positioned to have a predetermined angle with respect to the frame <NUM> in response to rotation. A friction member for providing a predetermined frictional force during rotation may be provided between fixing structures of the other end of the (<NUM>-<NUM>)-th link 80b2 and the other end of the frame <NUM>. Due to the friction member, the (<NUM>-<NUM>)-th link 80b2 may maintain the previous state thereof without rotating with respect to the frame <NUM> as long as the user does not provide a force equal to or greater than a preset level.

In this manner, the frame <NUM> fixed to the display module <NUM> can allow the translational motion and swivel motion of the display module <NUM> as described above according to the structures of the first link part 80a and the second link part 80b.

<FIG> is a diagram for describing the structure of the frame and the relationship between the frame and the spacer according to an embodiment of the present disclosure.

Referring to <FIG>, the display device according to the claimed invention includes spacers <NUM> and tilting holes <NUM> provided to allow a tilting motion of the display module <NUM>.

The display module <NUM> includes at least a pair of a first spacer 610a and a second spacer 610b. The first spacer 610a and the second spacer 610b are positioned at the rear of the display module <NUM> and may be disposed at an upper central portion. The first spacer 610a and the second spacer 610b may be respectively positioned on one side and the other side to be symmetrical with respect to a virtual axis crossing the center of the display module <NUM> in the vertical direction.

The frame <NUM> of the wall mount assembly <NUM> includes at least a pair of a first tilting hole 71a and a second tilting hole 71b. The first tilting hole 71a is formed at a position corresponding to the first spacer 610a in the frame <NUM> and the second tilting hole 71b is formed at a position corresponding to the second space 610b in the frame <NUM>. The first tilting hole 71a and the second tilting hole 71b may be respectively located on one side and the other side to be symmetrical with respect to a virtual axis crossing the center of the frame part <NUM> in the vertical direction.

The first spacer 610a and the second spacer 610b fixed to the display module <NUM> are fastened to the first tilting hole 71a and the second tilting hole 71b, respectively. The first tilting hole 71a and the second tilting hole 71b restrict movement of the first spacer 610a and the second spacer 610b fixed to the display module <NUM>. This means that movement of the display module <NUM> in at least one direction may be restricted in response to the shape of the tilting hole <NUM>. In addition, the first tilting hole 71a and the second tilting hole 71b guide moving paths of the first spacer 610a and the second spacer 610b fixed to the display module <NUM>. This means that the display module <NUM> is tilted or shifted in a preset direction in response to the shape of the tilting hole <NUM>.

<FIG> is a diagram for describing the shape of the spacer according to an embodiment of the present disclosure. <FIG> are diagrams for describing the structures of the spacer and the tilting hole according to an embodiment of the present disclosure.

Referring to <FIG>, the spacer <NUM> includes a spacer head <NUM> and a spacer neck <NUM>. The spacer head <NUM> and the spacer neck <NUM> may have different cross-sectional areas in a plan view. For example, the spacer head <NUM> and the spacer neck <NUM> may have cylindrical shapes having different diameters. That is, the spacer head <NUM> has a cylindrical shape having a first diameter FRD, and the spacer neck <NUM> may have a cylindrical shape extending from the spacer head <NUM> and having a second diameter SRD less than the first diameter FRD. Since the spacer <NUM> includes the spacer head <NUM> and the spacer neck <NUM> having different diameters, the spacer <NUM> may be easily fastened to at least one side of the tilting hole <NUM> which will be described later.

Referring to <FIG>, the frame <NUM> includes tilting holes <NUM>. The tilting hole <NUM> includes an inlet portion IP and a guide portion TP. The guide portion TP may be located lower than the inlet portion IP. The guide portion TP may be located lower than the inlet portion IP in a load direction (or the gravity direction).

The inlet portion IP may be a portion into/from which the spacer <NUM> is inserted/released. That is, the inlet portion IP may have a sufficient hole area through which both the spacer head <NUM> and the spacer neck <NUM> can be inserted into the inlet portion IP and released therefrom. In other words, the inlet portion IP may have a larger hole area than the first diameter FRD of the spacer head <NUM>. In other words, in the inlet portion IP, forward and backward movements of the spacer head <NUM> and the spacer neck <NUM> are not constrained. Although the inlet portion IP has a substantially circular shape in the figure, the present disclosure is not limited thereto. The inlet portion IP may have various planar figure shapes such as a rectangle, a square, and an oval.

The guide portion TP may include a seating part TP1 and first and second extension parts TP2 and TP3 extending from the seating part TP1 in one direction. The first extension part TP2 and the second extension part TP3 may extend in a reverse direction with respect to the seating part TP1. An extension line EL in the extension direction of the first and second extension parts TP2 and TP3 and a horizontal line HL in the horizontal direction intersect each other, and the angle θ therebetween is a tilting angle (dutch angle). The tilting angle means an inclined angle that is not vertical or horizontal. It may be desirable that an acute angle between the extension line EL and the horizontal line HL be <NUM>°<θ<<NUM>°.

The guide portion TP may be a part to which the spacer <NUM> is fixed in the tilting hole <NUM>. For example, the seating part TP1 may be a part where the spacer <NUM> moving along the shape of the tilting hole <NUM> in response to the movement of the display module <NUM> is first seated in the guide portion TP.

When a predetermined external force is provided, the display module <NUM> may be tilted in one direction and the spacer <NUM> may move along the shape of the guide portion TP in response thereto. The moving direction of the spacer <NUM> may be guided along the shape of the guide portion TP.

The guide portion TP has a hole area through which the spacer head <NUM> cannot be inserted into the guide portion TP and released therefrom. That is, the guide portion TP may have a smaller hole area than the first diameter FRD of the spacer head <NUM>. Accordingly, forward movement of the spacer head <NUM> inserted toward the rear of the frame <NUM> through the inlet portion IP is restricted by the guide portion TP. Accordingly, the spacer <NUM> is not separated from the guide portion TP. The guide portion TP has a hole area through which the spacer neck <NUM> can pass. That is, the guide portion TP may have a larger hole area than the second diameter SRD of the spacer neck <NUM>.

The tilting hole <NUM> may further include a link portion LP connecting the inlet portion IP and the guide portion TP. The link portion LP may serve as a moving path of the spacer <NUM> moving between the inlet portion IP and the guide portion TP. For example, the link portion LP may serve a moving path through which the spacer <NUM> inserted through the inlet portion IP moves to the guide portion TP such that the spacer <NUM> can be seated in the tilting hole <NUM>. On the other hand, the link portion LP may serve as a moving path through which the spacer <NUM> seated on the guide portion TP moves to the inlet portion IP such that the spacer <NUM> can be separated from the tilting hole <NUM>. Since the tilting hole <NUM> includes the link portion LP, a sufficient moving path of the spacer <NUM> may be secured. Accordingly, it is possible to prevent the spacer <NUM> seated on the guide portion TP from moving to the inlet portion IP by an unintentionally provided external force and thus being separated from the tilting hole <NUM>.

The link portion LP has a hole area through which the spacer head <NUM> cannot be inserted into the link portion LP and released therefrom. That is, the link portion LP may have a smaller hole area than the first diameter FRD of the spacer head <NUM>. Accordingly, forward movement of the spacer head <NUM> inserted toward the rear of the frame part <NUM> through the inlet portion IP is restricted by the link portion LP. Accordingly, the spacer <NUM> is not separated from the link portion LP. The link portion LP may have a hole area through which the spacer neck <NUM> can pass. That is, the guide portion TP may have a larger hole area than the second diameter SRD of the spacer neck <NUM>. The hole area of the link portion LP may be different from the hole area of the guide portion TP.

<FIG> are diagrams for describing the positional relationship and shape of a pair of spacers according to the present disclosure.

Referring to <FIG>, the display module <NUM> includes at least a pair of the first spacer 610a and the second spacer 610b. At least a pair of the first tilting hole 71a and the second tilting hole 71b are provided in the frame <NUM> of the wall mount assembly <NUM>.

The first spacer 610a is provided at a position corresponding to the first tilting hole 71a and movably inserted into the first tilting hole 71a. The second spacer 610b is provided at a position corresponding to the second tilting hole 71b and movably inserted into the second tilting hole 71b.

The display module <NUM> fastened to the frame <NUM> of the wall mount assembly <NUM> may be tilted in a preset direction. However, the current state (or fixed state) of the display module <NUM> coupled to the wall mount assembly <NUM> may be maintained until a predetermined external force is provided. The preset direction may be determined according to the positions and shapes of the first tilting hole 71a and the second tilting hole 71b. In particular, the preset direction may be determined according to the positions and shapes of the guide portion TP of the first tilting hole 71a (hereinafter referred to as a "first guide portion TPa") and the guide portion TP of the second tilting hole 71b (hereinafter referred to as a "second guide portion TPb").

The first guide portion TPa and the second guide portion TPb may be positioned on the line of a virtual arc ARC. The virtual arc ARC may mean a virtual curve connecting the center of the first guide portion TPa and the center of the second guide portion TPb. The virtual arc ARC may have a shape that is convexly curved downward (<FIG>) or convexly curved upward (<FIG>).

For example, the center of the first guide portion TPa and the center of the second guide portion TPb may be located on the line of the virtual arc ARC in areas corresponding to the left and right sides of the frame <NUM>, respectively. The virtual arc ARC may be an arc that is a part of the circumference of a circle having a virtual center point. In this case, the virtual center point may be located on a reference line RL crossing the center of the frame <NUM> in the vertical direction. The curvature of the virtual arc ARC may vary depending on the position of the center point on the reference line RL.

The center of the first guide portion TPa positioned on the line of the virtual arc ARC may correspond to the center of the first spacer 610a fixed to the display module <NUM>. In particular, the center of the first guide portion TPa positioned on the line of the virtual arc ARC may correspond to the center of the spacer neck <NUM> of the first spacer 610a. When the first spacer 610a has a cylindrical shape, the center of the first spacer 610a may be the center of a circle.

The center of the second guide portion TPb positioned on the line of the virtual arc ARC may correspond to the center of the second spacer 610b fixed to the display module <NUM>. In particular, the center of the second guide portion TPb positioned on the line of the virtual arc ARC may correspond to the center of the spacer neck <NUM> of the second spacer 610b. When the second spacer 610b has a cylindrical shape, the center of the second spacer 610b may be the center of a circle.

Referring to (a) of <FIG>, the extension direction of the first guide portion TPa may be a direction in which the tangent line TL of the virtual arc ARC passing through the centers of the first and second guide portions TPa and TPb extends. The extension direction of the second guide portion TPb forming a pair with the first guide portion TPa may be a direction in which the tangent line TL of the virtual arc ARC passing through the centers of the first and second guide portions TPa and TPb extends.

Referring to (b) of <FIG>, the extension direction of the first guide portion TPa may be a direction in which the virtual arc ARC passing through the centers of the first and second guide portions TPa and TPb extends. The extension direction of the second guide portion TPb forming a pair with the first guide portion TPa may be a direction in which the virtual arc ARC passing through the centers of the first and second guide portions TPa and TPb extends. In this case, the first guide portion TPa and the second guide portion TPb have a curved shape.

Referring to <FIG>, the first tilting hole 71a and the second tilting hole 71b may have symmetrical shapes. For example, the first tilting hole 71a and the second tilting hole 71b may be respectively located in areas corresponding to one side and the other side of the frame <NUM> such that they are line-symmetrical with respect to a virtual reference line RL. The virtual reference line RL may be a virtual straight line crossing the center of the frame <NUM> in the vertical direction. For example, a first angle θ1 formed between a first extension line EL1 extending in the extension direction of the first guide portion TPa and a horizontal line HL extending in the horizontal direction may be the same as a second angle θ2 formed between a second extension line EL2 extending in the extension direction of the second guide portion TPb and the horizontal line HL extending in the horizontal direction.

<FIG> are diagrams for describing a locking part according to an embodiment of the present disclosure.

Referring to <FIG>, the frame <NUM> according to the claimed invention includes a locking part <NUM>. The locking part <NUM> is fastened to the frame <NUM> and serves to selectively limit the moving path of the spacer <NUM> inserted into the tilting hole <NUM>. That is, the locking part <NUM> may serve to selectively open and close the moving path of the spacer <NUM> inserted into the tilting hole <NUM> according to user demand.

The locking part <NUM> is hinged to the frame <NUM> and may be provided rotatably with respect to the frame <NUM>. The locking part <NUM> may be located at the rear of the frame <NUM>. At least a portion of the locking part <NUM> may be positioned to overlap the tilting hole <NUM>.

More specifically, at least a portion of the locking part <NUM> may be positioned to correspond to the area between the inlet portion IP and the guide portion TP of the tilting hole <NUM> and may selectively restrict a moving path of the spacer <NUM> moving between the inlet portion IP and the guide portion TP. For example, at least a portion of the locking part <NUM> may be positioned to correspond to the link portion LP of the tilting hole <NUM> and may selectively restrict the moving path of the spacer <NUM> moving from the guide portion TP to the inlet portion IP, but the present disclosure is not limited thereto. At least a portion of the locking part <NUM> blocking the moving path of the spacer <NUM> may be referred to as a blocking part <NUM>.

The locking part <NUM> may have a rod shape elongated to have an approximately U-shape. The locking part <NUM> may have an open loop shape in which a part is opened. The locking part <NUM> may include at least one bent part or bending part but is not limited thereto.

One end and the other end of the locking part <NUM> may be rotatably coupled to the frame <NUM>. For example, the frame <NUM> may include a first through-hole 75a and a second through-hole 75b that penetrate in the vertical direction. One end of the locking part <NUM> may be rotatably coupled to the first through-hole 75a with respect to a virtual axis extending in the vertical direction, and the other end of the locking part <NUM> may be rotatably coupled to the second through-hole 75b with respect to the virtual axis extending in the vertical direction. The through-hole <NUM> may be formed in a protrusion <NUM> protruding backward from the frame <NUM>.

In a mode (or locking mode) in which the moving path of the spacer <NUM> is blocked, at least a portion of the locking part <NUM> may extend to cross the inlet portion IP to block the movement of the spacer <NUM> inserted into the guide portion TP to the inlet portion IP. In the locking mode, it is possible to prevent the spacer <NUM> inserted into the guide portion TP from being unintentionally moving to the inlet portion IP and being released from the tilting hole <NUM>.

In a mode (or unlocking mode) in which the moving path of the spacer <NUM> is open, at least a portion of the locking part <NUM> may be spaced apart from the frame <NUM> backward such that the movement of the spacer <NUM> inserted into the guide portion TP is not blocked. That is, since the moving path of the spacer <NUM> is not limited by the locking part <NUM> in the unlocking mode, the spacer <NUM> inserted into the guide portion TP can move to the inlet portion IP and be released from the tilting hole <NUM>.

The frame <NUM> may further include a stopper <NUM> for limiting the movement of the locking part <NUM> in the locking mode. The stopper <NUM> may have a shape protruding backward from the frame <NUM>. The stopper <NUM> may be positioned around the tilting hole <NUM>. The stopper <NUM> may be positioned around the inlet portion IP. The stopper <NUM> may extend from the periphery of the inlet portion IP along the shape of the inlet portion IP but is not limited thereto.

The lower surface 73a of the stopper <NUM> may be positioned to contact the blocking part <NUM>. That is, in the locking mode, the blocking part <NUM> of the locking part <NUM> may be in contact with the lower surface 73a of the stopper <NUM> and the upward movement thereof may be restricted by the stopper <NUM>. Accordingly, the movement of the spacer <NUM> can be restricted by the stopper <NUM> more effectively. That is, it is possible to effectively block the movement of the spacer <NUM> in the locking mode by further including the stopper <NUM>.

For example, in the locking mode, at least a portion of the locking part <NUM> may be positioned to surround the outer periphery of the stopper <NUM>.

The lower surface 73a of the stopper <NUM> may further include a trench <NUM>. The trench <NUM> may have a shape partially recessed from the lower surface 73a of the stopper <NUM> upward. The lower surface 73a of the stopper <NUM> on which the trench <NUM> is formed may have an inclined shape ((a) of <FIG>) or a rounded shape ((b) of <FIG>), but is not limited thereto.

The blocking part <NUM> of the locking part <NUM> may be positioned to overlap one end of the stopper <NUM> corresponding to the lower surface 73a of the stopper <NUM>. Accordingly, in the locking mode, at least a portion of the blocking part <NUM> of the locking part <NUM> can be accommodated in the internal space of the trench <NUM> and the backward movement thereof can be limited. That is, in the locking mode, the blocking part <NUM> of the locking part <NUM> may maintain a state in which it is accommodated in the internal space of the trench <NUM> unless an external force equal to or greater than a predetermined value is provided. Accordingly, it is possible to prevent the lock part <NUM> from being unintentionally released in the locking mode. On the other hand, in the unlocking mode, the user can release the blocking part <NUM> of the locking part <NUM> from the trench <NUM> by providing a predetermined force to the locking part <NUM>. In such a structure, since the user can recognize whether the locking part <NUM> is seated in the trench <NUM> or released from the trench <NUM> by a click sound or fingertip sense and thus can easily ascertain locking or unlocking.

<FIG> are diagrams for describing an auxiliary locking part according to an embodiment of the present disclosure.

Referring to <FIG>, the wall mount assembly according to an embodiment of the present disclosure may further include an auxiliary locking part <NUM>. The auxiliary locking part <NUM> is fixed to the fixing part <NUM> and may serve to selectively limit the movement of the frame <NUM>. The auxiliary locking part <NUM> may be an elastic member having predetermined elasticity. For example, the auxiliary locking part <NUM> may be a leaf spring, but is not limited thereto.

One end of the auxiliary locking part <NUM> may be fixed to the fixing part <NUM>. The other end of the auxiliary locking part <NUM> may extend downward from one end of the auxiliary locking part <NUM> and may be positioned to overlap at least a part of the frame <NUM> in the back-and-forth direction.

In a state in which the display module <NUM> is in a position close to the fixed object <NUM>, the other end of the auxiliary locking part <NUM> may be positioned in front of the frame <NUM> such that the forward movement of the frame <NUM> is restricted. The state in which the display module <NUM> is in a position close to the fixed object <NUM> may mean a state in which one surface of the (<NUM>-<NUM>)-th link 80a1 and the (<NUM>-<NUM>)-th link 80a2 constituting the first link part 80a are in contact with each other, one surface of the (<NUM>-<NUM>)-th link 80b1 and one surface of the (<NUM>-<NUM>)-th link 80b2 constituting the second link part 80b are in contact with each other. Alternatively, the state in which the display module <NUM> is in a position close to the fixed object <NUM> may mean a state in which the translational motion and the swivel motion of the display module <NUM> are restricted.

On the other hand, in a state in which the display module <NUM> is spaced apart from the fixed object <NUM>, the other end of the auxiliary locking part <NUM> may be located at the rear of the frame <NUM> such that the forward movement of the frame <NUM> is not restricted. The state in which the display module <NUM> is spaced apart from the fixed object <NUM> may mean a state in which one surface of the (<NUM>-<NUM>)-th link 80a1 and the (<NUM>-<NUM>)-th link 80a2 constituting the first link part 80a are spaced apart by a predetermined angle, and one surface of the (<NUM>-<NUM>)-th link 80b1 and one surface of the (<NUM>-<NUM>)-th link 80b2 constituting the second link portion 80b are spaced apart by a predetermined angle. Alternatively, the state in which the display module <NUM> is spaced apart from the fixed object <NUM> may mean a state in which the translational motion and the swivel motion of the display module <NUM> are permitted.
