The stand (1) may be called a display stand (1), a projector stand (1), a speaker stand (1), a lighting stand (1), etc.

[0035] For example, a rectangular display (DP) may include four lateral sides. The display (DP) may include a first long side (LS1), a second long side (LS2) located opposite the first long side (LS1), a first short side (SS1) adjacent to the first long side (LS1) and the second long side (LS2), and a second short side (SS2) opposite the first short side (SS1). Meanwhile, for convenience of explanation, the lengths of the first and second long sides (LS1, LS2) are depicted and described as being longer than the lengths of the first and second short sides (SS1, SS2), but it is also possible for the lengths of the first and second long sides (LS1, LS2) to be approximately the same as the lengths of the first and second short sides (SS1, SS2).

[0036] The first long side (LS1), the second long side (LS2), the first short side (SS1), and the second short side (SS2) can form the edges of the display (DP). The point where the first long side (LS1), the second long side (LS2), the first short side (SS1), and the second short side (SS2) meet each other can be called a corner. The point where the first long side (LS1) and the first short side (SS1) meet can be called the first corner (C1). The point where the first short side (SS1) and the second long side (LS2) meet can be called the second corner (C2). The point where the second long side (LS2) and the second short side (SS2) meet can be called the third corner (C3). The point where the second short side (SS2) and the first long side (LS1) meet can be called the fourth corner (C4).

[0038] The pole (20) can be extended from the base (10). The pole (20) can be extended vertically, and the lower end of the pole (20) can be connected to the base (10).

[0039] A support arm (30) may extend in a direction intersecting the pole (20). The support arm (30) may be coupled to the pole (20) adjacent to the top of the pole (20). The support arm (30) may be rotatably coupled to the pole (20). The axis of rotation of the support arm (30) may be parallel to the left-right axis (i.e., the x-axis). Rotation of the support arm (30) relative to the pole (20) may be referred to as tilting.

[0040] A bracket (40) can connect a support arm (30) and an object supported by a stand (1), such as a display (DP). One side of the bracket (40) can be connected to the end of the support arm (30). The other side of the bracket (40) can be connected to an object supported by the stand (1). The bracket (40) can be rotatably connected to the support arm (30). The bracket (40) can rotate about at least one axis. Rotation of the bracket (40) relative to the support arm (30) can be referred to as swivel, tilting, or pivoting. The bracket (40) may be a component of a joint (J) described later. The joint (J) may include a bracket (40), a connecting rod (50), and an arm mount (60). The joint (J) may be referred to as a bracket assembly (J). Meanwhile, at least one of the rotational structure of the support arm (30) or the rotational structure of the bracket (40) described above and below may be omitted.

[0041] The stand (1) can be detachably coupled to an object such as a display (DP) via a bracket (40). The stand (1) may be equipped with a support arm (30) and / or a pole (20) to keep the bracket (40) away from a wall or the ground. The stand (1) may be equipped with a base (10) to be placed stably on the ground. Accordingly, the stand (1) can support an object such as a display (DP).

[0042] Meanwhile, the base (10) can be called a stand base, and the pole (20), support arm (30), and joint (J) can be collectively called a stand body.

[0043]

[0044] Referring to FIG. 3, the bracket (40) may have a rectangular plate shape overall. The bracket (40) may be referred to as a fixed plate (40). For example, the bracket (40) may face the rear of the display (D, see FIG. 1). For example, the bracket (40) may be detachably coupled to the display (DP) by a hook or latch. The display (DP) may be fixed to the bracket (40) and rotate together with the bracket (40).

[0045] A connecting rod (50) can be connected to the rear of a bracket (40). The connecting rod (50) can extend in a direction that crosses the bracket (40). One side of the connecting rod (50) can be connected to a support arm (30, see FIG. 1) and can connect the bracket (40) and the support arm (30). The connecting rod (50) can be referred to as an ankle (50).

[0046] The cover (40C) can cover the rear of the bracket (40) and may include a hole (40CH) through which the connecting rod (50) passes. The inner cover (40A) can form the hole (40CH) and may be coupled to the rear of the bracket (40). The outer cover (40B) may be located outside the inner cover (40A) and may be located at the rear of the bracket (40).

[0047]

[0048] Referring to FIGS. 4 and 5, the connecting rod (50) may include a body (51), a pin (52), and a hub (53).

[0049] The body (51) may extend in a direction intersecting the bracket (40). The body (51) may be bent at least once or be a straight part. The first part (511) may form the rear portion of the body (51). The second part (512) may be located in front of the first part (511) and may form a step that rises from the first part (511). The third part (513) may be located in front of the second part (512) and may extend upward at an angle from the second part (512).

[0050] The pin (52) may protrude from the side of the body (51) adjacent to the front end of the body (51). The pin (52) may extend to the left and right of the third part (153) of the body (51). Threads may be formed on the outer surface of the pin (52). A coupling portion (40P) may protrude from the rear of the bracket (40), and the pin (52) may pass through the coupling portion (40P). A connecting rod (50) may be coupled to the bracket (40) by fastening a fastening member (40N), such as a nut, to the threads of the pin (52). The bracket (40) may rotate around the pin (52), and an elastic member (40S), such as a spring, may support the bracket (40). The rotation of the bracket (40) relative to the connecting rod (50) may be referred to as tilting.

[0051] A hub (53) may be formed in the rear portion of the body (51). The hub (53) may be referred to as a ring part (53). The upper surface of the first part (511) of the body (51) and the upper surface of the hub (53) may form a single plane. The lower surface of the first part (511) of the body (51) and the lower surface of the hub (53) may form a single plane. A hole (53H) may be formed by penetrating the upper and lower surfaces of the hub (53). The inner surface of the hole (53H) may be composed of a pair of curved surfaces and a pair of curved surfaces. The hole (53H) may be referred to as a Double-D Hole. A groove (53G) may be recessed from the upper surface of the hub (53) and may be formed around the hole (53H). The groove (53G) may extend in an arc with respect to the center of the hole (53H) and may be referred to as a C-shaped groove. For example, the angle between the two ends of the groove (53G) with respect to the center of the hole (53H) may be 180 degrees. The locking slot (53L) may be recessed from the upper surface of the hub (53) and may be formed between the hole (53H) and the groove (53G). The depth of the locking slot (53L) may be smaller than the depth of the groove (53G).

[0052]

[0053] Referring to FIG. 6, the mount body (61) of the arm mount (60) can be connected to the support arm (30). The arm mount (60) may be referred to as a coupler (60), a front bracket (60), or a first bracket (60). The mount body (61) may include a fixed part (611) and a coupling part (612).

[0054] The fixed portion (611) may form the front portion of the mount body (61). The fixed portion (611) may have the shape of a block with a relatively thin thickness. The fixed portion (611) may be referred to as a flat portion (611). A stopper (611S) may protrude from the lower surface of the fixed portion (611). The stopper (611S) may extend along an arc. The stopper (611S) may be formed in the central portion (611C) of the fixed portion (611).

[0055] The connecting portion (612) may form the rear portion of the mount body (61). The connecting portion (612) may protrude rearward from the fixed portion (611). The connecting portion (612) may include a first part (612L) and a second part (612R) that are spaced apart from each other in the left and right directions. The connecting portion (612) may be rotatably connected to the support arm (30).

[0056]

[0057] Referring to FIGS. 7 through 9, the bottom cover (62) of the arm mount (60) can cover the lower surface of the mount body (61). The bottom cover (62) can be coupled to the mount body (61). A central hole (62H) can be formed in the bottom cover (62) and can be positioned corresponding to the central part (611C) of the fixed part (611) of the mount body (61).

[0058] The connecting rod (50) may be located under the bottom cover (62). The upper surface of the hub (53) of the connecting rod (50) may face the lower surface of the central portion (611C) of the fixed portion (611). The upper surface of the hub (53) may come into contact with the lower surface of the central portion (611C). For example, at least one washer (W1) may be placed between the upper surface of the hub (53) and the lower surface of the central portion (611C). The washer (W1) may be a toothed lock washer that is secured in the locking slot (53L, see FIG. 4) of the hub (53).

[0059] The stopper (611S) may protrude from the lower surface of the central portion (611C) of the fixed portion (611) toward the groove (53G) of the hub (53). The stopper (611S) may be inserted into the groove (53G, see FIG. 4) and may be positioned between both ends of the groove (53G).

[0060] The shaft (59) may include a body (591) and a head (592). The body (591) may be extended. The body (591) may pass through the hole (53H) of the hub (53), the washer (W1), and the hole (611H) of the central portion (611C). The cross-section of the body (591) may correspond to the double-D shape of the hole (53H), thereby allowing the shaft (59) to rotate together with the connecting rod (50). However, the hole (611H) of the central portion (611C) may be a circular hole, thereby allowing the shaft (59) to rotate relative to the arm mount (60). The lower part of the body (591) may be thicker than the upper part of the body (591). The lower part of the body (591) may be located in the double-D shaped hole (53H). The head (592) may be formed at the bottom of the body (591) and may have a diameter larger than the diameter of the body (591). The head (592) may be engaged with the hub (53). The head (592) may be engaged with the bottom of a groove formed on the lower surface of the hub (53). The lower surface of the head (592) may be located at a higher level than or at the same level as the lower surface of the hub (53).

[0061] The fixing member (59F) can be fixed to the end of the body (591) of the shaft (59). For example, the fixing member (59F) can be a nut and can be screw-fastened to the body (591). The mount body (61) of the arm mount (60) can be sandwiched between the hub (53) and the fixing member (59F) by the shaft (59).

[0062] For example, at least one washer (W2) may be placed between the central part (611C) and the fixing member (59F), and the body (591) may pass through the washer (W2). For example, a disc spring (W3) may be placed between the central part (611C) and the fixing member (59F), and the body (591) may pass through the disc spring (W3). The disc spring (W3) may be convex upward or downward and may generate an elastic force in the axial direction of the shaft (59). By adjusting the connection length between the shaft (59) and the fixing member (59F), the frictional force between the hub (53) and the mount body (61) can be adjusted. The greater the frictional force, the greater the force required to rotate the connecting rod (50) around the shaft (59).

[0063] The receiving groove (611G) may be recessed from the upper surface of the central portion (611C) of the fixing portion (611). A washer (W2), a disc spring (W3), and a fixing member (59F) may be located in the receiving groove (611G). For example, at least one groove (611U) other than the receiving groove (611G) may be formed on the upper surface of the fixing portion (611), thereby reducing the weight of the mount body (61).

[0064]

[0065] Referring to FIGS. 9 and 10, the top cover (63) can cover the upper surface of the mount body (61). The top cover (63) can be coupled to the mount body (61). The bottom cover (62) and the top cover (63) can be fixed to the mount body (61). The shaft (59) and the fixing member (59F) can be fixed to the hub (53). Accordingly, the connecting rod (50) can be coupled to the arm mount (60) so as to be rotatable about the shaft (59).

[0066] The connecting rod (50) positioned under the bottom cover (62) may be suspended from the arm mount (60) by a shaft (59) connected from bottom to top to the arm mount (60). That is, because the connecting rod (50) rotates under the bottom cover (62), the connecting rod (50) and the shaft (59) can be hidden from the gaze of a user looking down at the arm mount (60).

[0067]

[0068] Referring to FIGS. 11 to 13, the bracket (40) and the connecting rod (50) can rotate relative to the arm mount (60). The center of rotation (O) of the bracket (40) and the connecting rod (50) can be formed on the shaft (59). In response to the rotation of the connecting rod (50), the position of the stopper (611S) of the arm mount (60) within the groove (53G) of the connecting rod (50) can be changed. In other words, in response to the rotation of the connecting rod (50), either of the two ends (53Ga, 53Gb) of the groove (53G) of the connecting rod (50) can be moved closer to the stopper (611S).

[0069] Referring to FIG. 11, the bracket (50) and the connecting rod (50) may face forward. The display (D, see FIG. 1) fixed to the bracket (50) may also face forward. The stopper (611S) may be positioned between the two ends (53Ga, 53Gb) of the groove (53G). At this time, the angle of the connecting rod (50) with respect to the center of rotation (O) may be defined as 0 degrees. For example, the stopper (611S) may be positioned closer to the other end (53Gb) than to one end (53Ga) of the groove (53G). Alternatively, the stopper (611S) may be positioned in the middle of the two ends (53Ga, 53Gb) of the groove (53G).

[0070] Referring to FIG. 12, the user can rotate the bracket (50) and the connecting rod (50) clockwise (CW). The rotation of the connecting rod (50) can be limited by the other end (53Gb) of the groove (53G) coming into contact with the stopper (611S). For example, when the connecting rod (50) rotates 60 degrees clockwise (CW) about the center of rotation (O), the other end (53Gb) of the groove (53G) may come into contact with the stopper (611S).

[0071] Referring to FIG. 13, the user can rotate the bracket (50) and the connecting rod (50) counterclockwise (CCW). The rotation of the connecting rod (50) can be limited by one end (53Ga) of the groove (53G) coming into contact with the stopper (611S). For example, when the connecting rod (50) rotates 90 degrees counterclockwise (CCW) about the center of rotation (O), one end (53Ga) of the groove (53G) may come into contact with the stopper (611S).

[0072] As the stopper (611S) and groove (53G) are formed inside the joint (60), they may not be exposed to the outside.

[0073]

[0074] Referring to FIG. 14, a support arm (30) can connect an arm mount (60) and a pole mount (70). The arm mount (60) can be attached to a bracket (40) adjacent to the front end of the support arm (30) (see FIG. 1). The arm mount (60) may be referred to as the first mount (60).

The first lower bar (311) and the second lower bar (312) may be spaced apart from each other in the horizontal direction. A lower fixer (313) may be placed between the first lower bar (311) and the second lower bar (312) and may connect the first lower bar (311) and the second lower bar (312). For example, the first lower fixer (313A) and the second lower fixer (313B) can connect the first lower bar (311) and the second lower bar (312). Alternatively, there may be one or three or more lower fixers (313). The lower fixer (313) may be referred to as a lower bridge (313). The lower arm (31) may be referred to as a lower bracket (31) or a first arm (31).

[0078] The upper arm (32) may extend along the lower arm (31). The upper arm (32) may include a first upper bar (321) and a second upper bar (322). The first upper bar (321) and the second upper bar (322) may extend along the longitudinal direction of the upper arm (32) and may face each other. The first upper bar (321) and the second upper bar (322) may be spaced apart from each other in the horizontal direction. An upper bridge (323) may be positioned between the first upper bar (321) and the second upper bar (322) and may connect the first upper bar (321) and the second upper bar (322). The upper bridge (323) may be referred to as an upper fixer (323). The upper arm (32) can be called the upper bracket (32) or the second arm (32).

[0079] Meanwhile, the upper arm (32) can cover the lower arm (31). The lower bars (311, 312) of the lower arm (31) can be placed between the upper bars (321, 322) of the upper arm (32). The upper bridge (323) of the upper arm (32) can cover the lower fixer (313) of the lower arm (31).

[0080] The supporter (33) may include an elastic member (331) having elasticity. The elastic member (331) may extend along the lower arm (31). The elastic member (331) may be positioned between the lower bars (311, 312) of the lower arm (31). The elastic member (331) may be a coil-shaped spring. The elastic member (331) may be extended or compressed. The support arm (30) equipped with the supporter (33) may support a force (moment) transmitted from the arm mount (60) to the support arm (30). The supporter (33) may be referred to as an elastic module (33) or a spring module (33).

[0081]

[0082] Referring again to FIG. 6, the arm mount (60) may be adjacent to the front end of the support arm (30). The connecting portion (612) of the arm mount (60) may be positioned between the lower bars (311, 312) of the lower arm (31). The first part (612L) of the connecting portion (612) may be adjacent to the inside of the first lower bar (311), and the second part (612R) of the connecting portion (612) may be adjacent to the inside of the second lower bar (312). Alternatively, instead of the first and second parts (612L, 612R), only a single part may be positioned between the lower bars (311, 312).

[0083] The first lower pin (P1, lower pin) may extend in a direction intersecting the first lower bar (311). The first lower pin (P1) may extend in a horizontal direction. The first lower pin (P1) may penetrate the first lower bar (311) and the first part (612L) of the coupling part (612), and may connect the first lower bar (311) to the first part (612L). A fixing member, such as a nut, may be fixed to the end of the first lower pin (P1), and at least one washer may be placed between the fixing member and the first part (612L). An arm mount (60) may be rotatably connected to the first lower bar (311) around the first lower pin (P1).

The first upper pin (P3) may penetrate the first upper bar (321) and the first part (612L) of the coupling part (612), and may connect the first upper bar (321) to the first part (612L). A fixing member, such as a nut, may be fixed to the end of the first upper pin (P3), and at least one washer may be placed between the fixing member and the first part (612L).

The distance between the first upper pin (P3) and the first lower pin (P1) may be equal to the distance between the first upper pin (P3') and the first lower pin (P1').

[0087]

[0088] Referring again to FIG. 15, the pole mount (70) may include a fixed part (71) and a coupling part (72).

[0089] The fixed portion (71) can form the lower part of the pole mount (70). The fixed portion (71) may have the shape of a block with a relatively thin thickness. The fixed portion (71) may extend in a vertical direction. The fixed portion (71) may be fixed to the pole (20, see FIG. 1). The fixed portion (71) may be inserted and fixed into the internal space of the upper part of the pole (20).

[0090] The connecting portion (72) can form the upper part of the pole mount (70). The connecting portion (72) can protrude upward from the fixing portion (71). The connecting portion (72) may include a first part (72L) and a second part (72R) that are spaced apart from each other in the left and right directions.

[0091] The pole mount (70) may be adjacent to the rear end of the support arm (30). The connecting portion (72) of the pole mount (70) may be positioned between the lower bars (311, 312) of the lower arm (31). The first part (72L) of the connecting portion (72) may be adjacent to the inside of the first lower bar (311), and the second part (72R) of the connecting portion (72) may be adjacent to the inside of the second lower bar (312). Alternatively, instead of the first and second parts (72L, 72R), only a single part may be positioned between the lower bars (311, 312).

[0092] The second lower pin (P2) may extend in a direction intersecting the first lower bar (311). The second lower pin (P2) may extend in a horizontal direction. The second lower pin (P2) may penetrate the first lower bar (311) and the first part (72L) of the coupling part (72), and may connect the first lower bar (311) to the first part (72L). A fixing member, such as a nut, may be fixed to the end of the second lower pin (P2), and at least one washer may be placed between the fixing member and the first part (72L). The lower arm (31) may be rotatably connected to the pole mount (70) around the second lower pin (P2).

[0093] The second lower pin (P2', lower pin) may extend in a direction intersecting the second lower bar (312). The second lower pin (P2') may extend in a horizontal direction. The second lower pin (P2') may penetrate the second lower bar (312) and the second part (72R) of the coupling part (72), and may connect the second lower bar (312) to the second part (72R). A fixing member, such as a nut, may be fixed to the end of the second lower pin (P2'), and at least one washer may be placed between the fixing member and the second part (72R). The lower arm (31) may be rotatably connected to the pole mount (70) around the second lower pin (P2'). The second lower pins (P2, P2') may be located on the same axis.

[0094] The second upper pin (P4) may extend in a direction intersecting the first upper bar (321). The second upper pin (P4) may extend in a horizontal direction. The second upper pin (P4) may penetrate the first upper bar (321) and the first part (72L) of the coupling part (72), and may connect the first upper bar (321) to the first part (72L). A fixing member, such as a nut, may be fixed to the end of the second upper pin (P4), and at least one washer may be placed between the fixing member and the first part (72L). The upper arm (32) may be connected to the pole mount (70) so as to be rotatable around the second upper pin (P4).

[0095] The second upper pin (P4') may extend in a direction intersecting the second upper bar (322). The second upper pin (P4') may extend in a horizontal direction. The second upper pin (P4) may penetrate the second upper bar (322) and the second part (72R) of the coupling part (72), and may connect the second upper bar (322) to the second part (72R).

The upper arm (32) may be rotatably connected to the pole mount (70) around the second upper pin (P4'). The second upper pins (P4, P4') may be located on the same axis. The second upper pins (P4, P4') may be offset backward from the second lower pins (P2, P2'). The distance between the second upper pin (P4) and the second lower pin (P2) may be equal to the distance between the second upper pin (P4') and the second lower pin (P2').

[0096]

[0097] Referring to FIGS. 16 to 18, the supporter (33) may include an elastic member (331), an adjusting member (332), a block (333), and a shaft (334). The adjusting member (332) may be referred to as a spring adjust casting.

[0098] The elastic member (331) may extend along the lower arm (31). The elastic member (331) may be a coil-shaped spring. One end of the elastic member (331) may be fixed to the lower fixer (313) of the lower arm (31). For example, a part of the elastic member (331) may have a hook shape and be fixed to the lower fixer (313). The elastic member (331) may support the lower fixer (313).

[0099] The adjusting member (332) may be adjacent to the other end of the elastic member (331). The other end of the elastic member (331) may be fixed to the adjusting member (332). For example, a part of the elastic member (331) may have a hook shape and be fixed to the adjusting member (332). The elastic member (331) between the lower fixer (313) and the adjusting member (332) may be compressed or extended.

[0100] The block (333) can be fixed to the upper arm (32) adjacent to the adjusting member (332). For example, the block (333) can be fixed to the upper bridge (323) of the upper arm (32) by means of a fastening member such as a screw. The adjusting member (332) can be coupled to the block (333) so as to be movable in the longitudinal direction of the support arm (30). A portion of the adjusting member (332) can be inserted into the guide groove (333G) of the block (333). The side wall of the guide groove (333G) surrounds the side of the adjusting member (332), so that the block (333) can restrict the rotation of the adjusting member (332) and allow only linear movement of the adjusting member (332).

[0101] The shaft (334) may be extended and may be coupled to the block (333) so as to be rotatable about the longitudinal axis of the shaft (334). The shaft (334) may include a body (3341) and a head (3342). The body (3341) may penetrate the block (333) and be inserted into the insertion groove (332G) of the adjusting member (332). Threads may be formed on the outer surface of the body (3341) and may be screw-coupled to the inner surface of the groove (332G). The head (3342) may be caught on the rear end of the block (333). A groove (334G) may be formed in the head (3342). The groove (334G) may be referred to as a wrench groove (334G). The shaft (334) may be a bolt or a screw.

[0102] Accordingly, the shaft (334) can connect the adjusting member (332) to the block (333). In addition, the adjusting member (332) can move in a linear reciprocating motion in response to the rotation of the shaft (334).

[0103] The projection (333P) can be fixed to the block (333) and inserted into the slot (332S) of the adjustment member (332). The projection (333P) can protrude from the side wall of the guide groove (333G) of the block (333) into the inside of the guide groove (333G). The projection (333P) may be the body of a screw fixed to the block (333). The slot (332S) may be formed on the outer surface of the adjustment member (332) and may extend in the direction of movement of the adjustment member (332). The movement of the adjustment member (332) may be restricted by either end of the slot (332S) coming into contact with the projection (333P). Accordingly, the range of movement of the adjustment member (332) may be limited.

[0104]

[0105] Referring again to FIG. 15, the supporter (33) may include two elastic members (331A, 331B) adjacent to each other. The elastic members (331A, 331B) may be fixed to the lower fixer (313) and the adjusting member (332). Alternatively, the number of elastic members (331) of the supporter (33) may be one or three or more.

[0106] The support arm (30) may include two supporters (33A, 33B) arranged along the longitudinal direction of the support arm (30). The first supporter (33A) may be positioned at the rear end of the support arm (30). The elastic member (331) of the first supporter (33A) may be fixed to the first lower fixer (313A), and the block (333) of the first supporter (33A) may be fixed to the upper arm (32) adjacent to the rear end of the support arm (30). The elastic member (331) of the second supporter (33B) may be fixed to the second lower fixer (313B), and the block (333) of the second supporter (33B) may be fixed to the upper arm (32) adjacent to the first lower fixer (313A). For example, the length of each elastic member (331) may be less than half the length of the support arm (30). Accordingly, a large force can be provided to the support arm (30) with elastic members (331) of relatively short length. Alternatively, the number of supporters (33) of the support arm (30) may be one or three or more.

[0107] The upper cover (30U, see FIG. 14) can cover the top of the upper arm (32, see FIG. 14) and can be coupled to the upper arm (30U). The upper cover (30U) can form the top of the support arm (30). The lower cover (30D, see FIG. 14) can cover the bottom of the lower arm (31) and can be coupled to the upper cover (30U). The lower cover (30D) can form the bottom of the support arm (30).

[0108]

[0109] Referring to FIGS. 19 and 20, the support arm (30) can rotate relative to the pole mount (70). Rotation of the support arm (30) relative to the pole mount (70) can be referred to as tilting of the support arm (30). The arm mount (60) can rotate relative to the support arm (30).

[0110] The lower arm (31), upper arm (32), and pins (P1, P2, P3, P4, P1', P2', P3', P4', see FIG. 6 and 15) may be four-bar linkages connecting the arm mount (60) and the pole mount (70). For example, the distance between the center axis of the first lower pins (P1, P1') and the center axis of the first upper pins (P3, P3') may be equal to the distance between the center axis of the second lower pins (P2, P2') and the center axis of the second upper pins (P4, P4'). In this case, the angle of the arm mount (60) relative to the pole mount (70) may be kept constant regardless of the rotation (tilt) angle of the support arm (30) (see FIG. 19 and 20). Accordingly, the angle of the bracket (40) attached to the arm mount (60) can also be maintained at a constant level.

[0111] The length of the elastic member (331) of the supporter (33) can be varied according to the rotation (tilting) of the support arm (30). The supporter (33) can provide a force capable of counteracting the moment applied from the arm mount (60) to the support arm (30).

[0112] Referring to FIGS. 19 and 20 in order, the support arm (30) can rotate in a first rotational direction (RD1). That is, the support arm (30) can be tilted downward. In response, the elastic member (331) can be stretched (tensioned) while elastically deforming. Due to the force provided by the elastic member (331), the support arm (30) can maintain a state of being tilted downward.

[0113] Referring to FIGS. 19 and 20 in reverse order, the support arm (30) can rotate in a second rotational direction (RD2). That is, the support arm (30) can be tilted upward. In response, the elastic member (331) can be shortened to a length close to its original length while elastically restoring. Due to the force provided by the elastic member (331), the support arm (30) can maintain an upwardly tilted state.

[0114]

[0115] Referring to FIGS. 21 and 22, a fixed cap (73) can be fixed to a connecting portion (72) of a pole mount (70). The fixed cap (73) may have a coin shape. A first fixed cap (73L) may cover the outer surface of a first connecting portion (72L) and may be fixed to the first connecting portion (72L). A second fixed cap (73R) may cover the outer surface of a second connecting portion (72R) and may be fixed to the second connecting portion (72R).

[0116]

[0117] Referring to FIGS. 22 and 23, a slip ring (74) can wrap around the side of a fixed cap (73). The slip ring (74) can be rotatably coupled to the fixed cap (73). The ring body (741) of the first slip ring (74L) can wrap around the side of the first fixed cap (73L) and can rotate around the first fixed cap (73L). The fixed portion (742) of the first slip ring (74L) can protrude from the ring body (741) and can be fixed to the lower cover (30D). The ring body (741) of the second slip ring (74R) can wrap around the side of the second fixed cap (73R) and can rotate around the second fixed cap (73R). The fixing part (742) of the second slip ring (74R) can protrude from the ring body (741) and can be fixed to the lower cover (30D).

[0118] Accordingly, in response to the rotation of the support arm (30), the slip ring (74) can rotate relative to the fixed cap (73).

[0119]

[0120] Referring again to FIG. 14, a fixed cap (68) can be fixed to a coupling portion (612) of an arm mount (60). The fixed cap (68) may have a coin shape similar to a fixed cap (73). A first fixed cap (68L) can cover the outer surface of a first coupling portion (612L) and can be fixed to the first coupling portion (612L). A second fixed cap (68R) can cover the outer surface of a second coupling portion (612R) and can be fixed to the second coupling portion (612R).

[0121] The slip ring (69) can wrap around the side of the fixed cap (68). The slip ring (69) can be rotatably coupled to the fixed cap (68). The ring body (691) of the first slip ring (69L) can wrap around the side of the first fixed cap (68L) and can rotate around the first fixed cap (68L). The fixed portion (692) of the first slip ring (69L) can protrude from the ring body (691) and can be fixed to the lower cover (30D). The ring body (691) of the second slip ring (69R) can wrap around the side of the second fixed cap (68R) and can rotate around the second fixed cap (68R). The fixed portion (692) of the second slip ring (69R) can protrude from the ring body (691) and can be fixed to the lower cover (30D).

[0122] Accordingly, in response to the rotation of the support arm (30), the slip ring (69) can rotate relative to the fixed cap (68).

[0123]

[0124] Referring to FIGS. 23 and 24, a dial (80) may be positioned between a first part (72L) and a second part (72R) of a pole mount (70). The dial (80) may have a coin shape. The central axis (A) of the dial (80) may extend horizontally through the center of the dial (80) and may penetrate the first part (72L) and the second part (72R). The dial (80) may be referred to as a disc (80) or a rotary member (80). The dial (80) may include a body (81) and a through hole (82).

[0125] The body (81) may have a round tray shape. The body (81) may be opened to the left or right. Alternatively, the body (81) may have a solid flat cylinder shape.

[0126] A through hole (82) may be formed by penetrating the body (81) in the radial direction of the body (81). The length of the through hole (82) may correspond to the diameter of the body (81). In the radial direction of the body (81), the entrance (82i) and the exit (82e) of the through hole (82) may be located on the same axis. A pair of walls (81W) may be formed on the inner surface of the body (81), and the through hole (82) may be formed between the pair of walls (81W). The through hole (82) may be referred to as a channel (82) or a path (82).

[0127] The projection (83) may protrude from the outer surface of the body (81). The projection (83) may be adjacent to the entrance (82i).

[0128] A slide (80A, see FIG. 14) may be positioned between the first part (72L) and the second part (72R) of the pole mount (70). The slide (80A) may be fixed to the pole mount (70). The slide (80A) may form part of a hollow cylinder. The curved surface (80R) of the slide (80A) facing the body (81) of the dial (80) may extend along the outer surface of the body (81) and may support the body (81). The dial (80) may rotate about an axis (A) on the curved surface (80R) of the slide (80A).

[0129]

[0130] Referring to FIGS. 23 and 25, the slide cover (80B) can cover the dial (80) on the slide (80A) and can be coupled to the slide (80A). The slide cover (80B) can form a hollow cylinder together with the slide (80A). The dial (80) can rotate within the hollow space of the cylinder formed by the slide (80A) and the slide cover (80B).

[0131] Meanwhile, the slide (80A) and the slide cover (80B) may be collectively referred to as the cover assembly (80A, 80B). The cover assembly (80A, 80B) may be positioned between a pair of slip rings (74L, 74R). While the pair of slip rings (74L, 74) rotate together with the support arm (30), the cover assembly (80A, 80B) may not rotate.

[0132]

[0133] Referring to FIG. 26, the support arm (30) can be rotated relative to the pole mount (70) to tilt-down (see arrow in FIG. 26). Conversely, the support arm (30) can be rotated relative to the pole mount (70) to tilt-up. That is, depending on the tilt of the support arm (30), the height of the bracket (40) attached to the support arm (30) can be adjusted.

[0134]

[0135] Referring to FIG. 27, the slide cover (80B) may be provided with a slot (80S) in which a projection (83) of the dial (80) is located. The slot (80S) may extend in the circumferential direction of the slide cover (80B). The length of the slot (80S) may be greater than the width (diameter) of the projection (83). Accordingly, the dial (80) may rotate between the two ends of the slot (80S). That is, the rotation of the dial (80) may be limited by the projection (83) touching either of the two ends of the slot (80S).

[0136] When the support arm (30) is tilted down (maximum), the projection (83) may be adjacent to the bottom of the slot (80S). The user can rotate the dial (80) by moving the projection (83) inside the slot (80S) upward. Accordingly, the through hole (82) of the dial (80) located below the projection (83) may be exposed to the outside. Alternatively, the user can rotate the dial (80) by moving the projection (83) inside the slot (80S) downward, and the through hole (82) may be covered by the slide cover (80B). Accordingly, the internal configuration of the support arm (30) can be hidden by the dial (80).

[0137]

[0138] Referring to FIGS. 28 and 29, the groove (334G) of the shaft (334) of the tilt-down support arm (30) may be exposed to the outside through the through hole (82) of the dial (80). The groove (334G) may be located in a straight line with the through hole (82). The groove (334G) may be aligned with the through hole (82). That is, the user can align the groove (334G) with the hole (82) by rotating the dial (80).

[0139] The user can insert the tool (W) into the through hole (82) and engage it with the groove (334G). For example, the tool (W) may be a hexagonal wrench. The tool (W) may be called an L-shaped wrench. The user can move the adjusting member (332) by rotating the shaft (334) with the tool (W).

[0140] When the user rotates the tool (W) clockwise (CW), the adjustment member (332) can move backward along the threads of the shaft (334). That is, the adjustment member (332) can be pulled backward, and in response, the length of the elastic member (331) fixed to the adjustment member (332) can be increased. As the length of the elastic member (331) increases, the deformation of the elastic member (331) increases, and the tensile force can be increased.

[0141] When the user rotates the tool (W) counterclockwise (CCW), the adjustment member (332) can move forward along the threads of the shaft (334). That is, the adjustment member (332) can be pushed forward, and in response, the length of the elastic member (331) fixed to the adjustment member (332) can be shortened. As the length of the elastic member (331) becomes closer to its original length, the deformation of the elastic member (331) becomes smaller, and the tensile force can be reduced.

[0142] Accordingly, the user can adjust the tension of the elastic member (331) using the tool (W). By adjusting the force applied to the elastic member (331) in this way, the user can adjust the amount of force required to rotate (tilt) the support arm (30). In other words, the tilting of the support arm (30) can be adjusted to be smoother or tighter.

[0143]

[0144] Referring to FIGS. 30 and 31, a cable (C) can be wired to a pole (20). The cable (C) can be wired to a support arm (30) by passing through a second fixing cap (73R). The cable (C) can be positioned between a first guide projection (731) and a second guide projection (732) inside the second fixing cap (73R). A cable holder (30K) of the support arm (30) can be formed in a lower cover (30D) and can hold the cable (C).

[0145] The cable (C) can be wired to the arm mount (60) by passing through the second fixing cap (68R). The cable (C) can be positioned between the first guide projection (681) and the second guide projection (682) inside the second fixing cap (68R). A cable slot (62S) of the arm mount (60) can be formed in the bottom cover (62), and the cable (C) can pass through the cable slot (62S). The cable (C) can be electrically connected to a display (DP) fixed to the bracket (40).

[0146]

[0147] Referring to FIGS. 1 to 31, the stand (1) may include: a bracket (40); a mount (70) spaced apart from the bracket (40); a support arm (30) connecting the bracket (40) and the mount (70); a support arm (30) rotatably coupled to the mount (70); and a dial (80) coupled to the mount (70) adjacent to the support arm (30), and the support arm (30) may include: an elastic member (331) whose length changes in response to rotation of the support arm (30); and a movable adjustment member (332) to which one end of the elastic member (331) is fixed, and the dial (80) may include a through hole (82) that is rotatable with respect to the mount (70) and is positioned corresponding to the adjustment member (332) at a specific angle of the dial (80).

[0148] The stand (1) may further include a cover assembly (80A, 80B) having a slot (80S) and a cover assembly (80A, 80B) that surrounds the dial (80) and is fixed to the mount (70).
