[0098] The pins 612 and 622 of the connector 60 provide a swivel axis for the connector 40 with the retaining portion 46. The retaining portion 46 can rotate about the pins 612 and 622. Due to the friction between the rear portion 463 and the bases 611 and 621, a force of a specified magnitude is required to rotate the retaining portion 46. Alternatively, the connector 60 may also have a disc spring for increasing the friction of the retaining portion 46. The disc spring may include at least one of a first disc spring and a second disc spring.

[0099] The first disc spring can be located between the top surface of the rear portion 463 and the bottom surface of the upper base 611. The upper pin 612 can pass through the first disc spring. The first disc spring can be located between the top surface of the rear portion 463 and the washer 616, or between the washer 616 and the bottom surface of the upper base 611. The first disc spring can protrude upwards or downwards and is elastic. The first disc spring can generate an axial elastic force and increase the friction between the rear portion 463 and the upper base 611.

[0100] The second disc spring can be located between the bottom surface of the rear portion 463 and the top surface of the lower base 621. The lower pin 622 can pass through the second disc spring. The second disc spring can be located between the bottom surface of the rear portion 463 and the washer 624, or between the washer 624 and the top surface of the lower base 621. The second disc spring can protrude upwards or downwards and is elastic. The second disc spring can generate an axial elastic force and increase the friction between the rear portion 463 and the lower base 621.

[0101] The rotation of the retaining portion 46 relative to the pins 612 and 622 can be restricted by the contact between the middle portion 462 of the retaining portion 46 and one end of the walls 613 and 623. For example, the connector 40 having the retaining portion 46 can rotate within a range of +90 to -90 degrees.

[0102] Reference Figure 9 and Figure 10 The cable groove 623G can be formed on the bottom surface of the lower wall 623. The cable groove 614G can be formed on the bottom surface of the coupling member 614.

A protrusion 40Pa formed on the side wall 40E of the connector 40 can be inserted into a groove formed on the side wall of the mounting member 15M. A protrusion extending from the side wall of the mounting member 15M can be inserted into a groove 40Sa formed on the side wall 40E of the connector 40. Here, the portion 41b forming the front side of the connector 40 can form the groove 40Sa.

[0111] The top base 681 may face the top surface of the upper base 611 of the upper body 61. The top base 681 may be generally circular plate-shaped. The side wall 681b of the top base 681 may protrude downward from the edge of the top 681a of the top base 681 and extend along said edge. A protrusion 681P may protrude from the inner side of the side wall 681b. The protrusion 681P may be referred to as hook 681P.

[0112] The top dome 682 can extend rearward from the top base 681. The top dome 682 can cover the coupling member 614 of the upper body 61. The top dome 682 can be generally shaped as an upwardly convex dome. The protrusion 682P can protrude from the inner side of the top dome 682.

[0115] A guide hole 614H can be formed in the coupling member 614 and located at the position corresponding to the guide pin 682G of the top dome 682. The guide pin 682G can be inserted into the guide hole 614H. Thus, the guide pin 682G and the guide hole 614H can guide the engagement of the top cover 68 and the upper body 61.

[0116] and Figure 11 Refer to together Figure 14 and Figure 15 The bottom cover 69 may include a bottom base 691 and a bottom dome 692.

[0117] The bottom base 691 may face the lower side of the lower body 62. The bottom base 691 may be generally circular plate-shaped. The side wall 691b of the bottom base 691 may protrude upward from the edge of the bottom 691a of the bottom base 691 and extend along the edge. The joint 691C may protrude from the inner side of the bottom 691a. The joint 691C may be formed by pressing upward from the outer side of the bottom 691a. The first joint 691Ca and the second joint 691Cb may be spaced apart from each other.

[0118] A bottom dome 692 extends rearward from the bottom base 691. The bottom dome 692 can cover the coupling member 614 of the upper body 61. The bottom dome 692 can be generally shaped as a downwardly projecting dome. A hole 692H or a groove 692H can be formed on the side of the bottom dome 692 and located at a position corresponding to the protrusion 682P of the top dome 682. A first groove 692Ha can be formed on the left side of the bottom dome 692, and a second groove 692Hb can be formed on the right side of the bottom dome 692. A first protrusion 682Pa of the top dome 682 can hook into the first groove 692Ha. A second protrusion 682Pb of the top dome 682 can hook into the second groove 692Hb. Thus, the bottom cover 69 can be attached to the top cover 68.

[0119] A cable groove 692G may be formed on the inner surface of the bottom dome 692 and face the cable groove 614G of the coupling member 614. A cable C may be disposed between the cable groove 692G of the bottom dome 692 and the cable groove 614G of the coupling member 614.

[0120] Hole 623H can be formed on the bottom surface of the lower wall 623 of the lower body 62. Groove 623R can be recessed from the bottom surface of the lower wall 623, and hole 623H can be formed at the bottom of groove 623R. The connecting portion 691C of the bottom base 691 can be inserted into groove 623R. The first connecting portion 691Ca can be aligned with the first hole 623Ha formed in the first groove 623Ra, and the second connecting portion 691Cb can be aligned with the second hole 623Hb formed in the second groove 623Rb. Fastening member F9 can pass through the connecting portion 691C of the bottom cover 69 and be connected to hole 623H. Fastening member F9 can be a bolt or screw. Thus, top cover 68 and bottom cover 69 can be fixed to joint 60.

[0121] Reference Figure 16 The cover 60C can cover the connector 60. A groove 60CS can be formed on the front part of the side of the cover 60C, and the groove 60CS can be a U-shaped opening. The groove 60CS can have a length corresponding to the rotation trajectory of the retaining part 46. One end of the groove 60CS can be located adjacent to one end of the walls 613, 623 of the connector 60. The other end of the groove 60CS can be located adjacent to the other end of the walls 613, 623 of the connector 60. Thus, the retaining part 46 can rotate relative to the connector 60 to which the cover 60C is attached.

[0122] Cable C can be disposed between the bottom base 691 of the bottom cover 69 and the lower body 62 of the connector 60. A cable path can be formed between the two ends of the lower wall 623 in the rotational direction of the retaining part 46. Cable C can run along the support arm 50 and the rod 30 (see reference).

If connector 40 is attached to the display 10 (see reference...) Figure 2 If the cable C is connected to the display 10, then the cable C can be electrically connected to the display 10.

[0123] For example, cable C can be electrically connected to the battery (not shown) of display 10. Cable C can provide power to the battery of display 10. In this case, if display 10 is connected to connector 40, the battery of display 10 is charged. Display 10, detached from connector 40, can be driven using the power of the battery.

The disc spring S4 can protrude towards the head P40 of the second upper pin P4 or towards the second upper fixing member N4 and is elastic. The disc spring S4 can generate an axial elastic force and increase the friction between the upper arm 52 and the arm mount 39.

[0155] Reference Figure 23 and Figure 24 The upper bridging portion 523 of the upper arm 52 can cover the block 534 of the support member 53.

[0156] The fastening member F4 can pass through the top hole 523T of the upper bridging portion 523 and be attached to the block 534. The fastening member F4 can be a screw. Thus, the block 534 can be fixed to the upper arm 52.

[0157] The fastening member F5 can pass through the side holes 521S and 522S of the upper rods 521 and 522 and the elongated holes 511S and 512S of the lower rods 511 and 512, and be engaged with the block 534. The fastening member F5 and the block 534 can move along the elongated holes 511S and 512S. The elongated holes 511S and 512S can each be bent. The curvature of the elongated holes 511S and 512S can correspond to the rotation trajectory of the lower arm 51. Thus, the block 534 can be movably engaged with the lower arm 51.

[0158] Reference Figure 24 and Figure 25 The support arm 50 can rotate relative to the arm mount 39. This rotation of the support arm 50 relative to the arm mount 39 can be referred to as tilting of the support arm 50. The coupling member 614 of the connector 60 can rotate relative to the support arm 50.

[0159] The lower arm 51 can rotate about an axis parallel to the second lower pin P2. The upper arm 52 can rotate about an axis parallel to the second upper pin P4. The connector 60 can rotate about an axis parallel to the first lower pin P1. The connector 60 can rotate about an axis parallel to the first upper pin P3.

[0160] The length of the elastic member 531 of the support member 53 can vary with the rotation (tilt) of the support arm 50. The support member 53 can provide a force to counteract the torque applied to the support arm 50 from the joint 60.

[0161] For example, refer to in sequence Figure 24 and Figure 25 The support arm 50 can rotate in the first rotation direction RD1. That is, the support arm 50 can tilt downwards. Correspondingly, the block 534 can move rearwards along the elongated hole 512S. At this time, the stop 532 can also move rearwards together with the block 534, and the elastic member 531 can elastically deform and stretch. Through the force provided by the elastic member 531, the support arm 50 can maintain its downward tilted state.

[0162] For example, reverse reference Figure 24 and Figure 25 The support arm 50 can rotate in the second rotation direction RD2. That is, the support arm 50 can tilt upward. Correspondingly, the block 534 can move forward along the elongated hole 512S. At this time, the stop member 532 can also move forward with the block 534, and the elastic member 531 can elastically return to its original position. Through the force provided by the elastic member 531, the support arm 50 can maintain its upward tilted state.

[0163] The lower arm 51, upper arm 52, and pins P1, P2, P3, and P4 can be a four-bar linkage connecting the connector 60 and the arm mount 39. For example, the distance between the central axes of the first lower pin P1 and the first upper pin P3 can be the same as the distance between the central axes of the second lower pin P2 and the second upper pin P4. In this case, the angle of the connector 60 relative to the arm mount 39 can remain constant, regardless of the tilt angle of the support arm 50. For example, the angle of the connector 60 can be the angle between a vertical axis passing through the center of the arm mount 39 and the top surface of the coupling member 614 of the connector 60. Thus, the angle of the display 10 coupled to the connector 60 can also remain constant.

[0164] and Figure 19 and Figure 23 Refer to together Figure 26 and Figure 27 A lower groove 51T may be formed on the first lower rod 511 and / or the second lower rod 512. The first lower groove 511T may be formed at the rear end of the first lower rod 511. The second lower groove 512T may be formed at the rear end of the second lower rod 512.

[0165] A stopper T may be engaged with or formed on the left and / or right side of the arm mount 39. The stopper T may be the head of a screw fixed to the arm mount 39. The stopper T may protrude from the side of the arm mount 39. A first stopper Ta may protrude from the left side of the arm mount 39. A second stopper Tb (see reference) Figure 31 It can protrude from the right side of the arm mount 39. The stop T can be located on the rotation trajectory of the lower groove 51T. The lower groove 51T can be a groove corresponding to the shape of the side of the stop T.

[0166] The lower groove 51T can contact the stop T, thereby limiting the downward tilting of the support arm 50. That is, if the first lower groove 511T contacts the first stop Ta or the second groove 512T contacts the second stop Tb, the downward tilting of the support arm 50 will stop.

[0167] An upper groove 52T may be formed on the first upper rod 521 and / or the second upper rod 522. The first upper groove 521T may be formed at the rear end of the first upper rod 521. The second upper groove 522T may be formed at the rear end of the second upper rod 522.

[0168] The second lower fixing member N2 can be located on the rotation trajectory of the first upper groove 521T. The first upper groove 521T can be a groove corresponding to the shape of the side of the second lower fixing member N2. The head P20 of the second lower pin P2 (refer to...) Figure 21It can be located on the rotation trajectory of the second upper groove 522T. The second upper groove 522T can be a groove with a shape corresponding to the side of the head P20.

[0169] The upper groove 52T can contact the head P20 of the second lower fixing member N2 or the second lower pin P2, thereby limiting the downward tilting of the support arm 50. That is, if the first upper groove 521T contacts the second lower fixing member N2 or the second upper groove 522T contacts the head P20 of the second lower pin P2, the downward tilting of the support arm 50 will stop.

[0170] Therefore, both the lower arm 51 and the upper arm 52 may have a groove that restricts the downward tilting of the support arm 50. Alternatively, only either the lower arm 51 or the upper arm 52 may have a groove that restricts the downward tilting of the support arm 50.

[0171] Reference Figure 28 and Figure 29 The groove 533g can be formed at the head 533a of the shaft 533. For example, the groove 533g can be a hexagonal groove.

[0172] A through-hole 39h may be formed in the arm mount 39. The through-hole 39h may be formed by obliquely penetrating the arm mount 39. The through-hole 39h may be referred to as a channel 39h or a path 39h. The position of the groove 533g of the shaft 533 may correspond to the position of the through-hole 39h along its length. The axis along the length of the through-hole 39h may be inclined downwards at approximately 10 degrees from the central axis of the shaft 533. The user can see the groove 533g of the shaft 533 through the through-hole 39h.

[0173] and Figure 29 Refer to together Figure 30 and Figure 31 The user can engage tool W with the slot 533g of shaft 533 through through hole 39h. For example, tool W can be a hex wrench. Tool W can be called an L-shaped wrench. The user can adjust the position of stop 532 by rotating shaft 533 using tool W. Elastic member 531 can be located between fixed member 53F and head 532a of stop 532. Both sides of head 532a of stop 532 can contact the lower rods 511, 512 of lower arm 51, and the rotation of head 532a can be restricted by the lower rods 511, 512. Shaft 533 can be threaded into the inner surface of the hole of stop 532 through which shaft 533 passes, and stop 532 can reciprocate linearly along shaft 533 corresponding to the rotation of shaft 533.

[0174] If the user rotates tool W and shaft 533 clockwise CW, stop 532 can move toward fixed member 53F (see reference). Figure 19 If the axis 533 is rotated counterclockwise, the stop 532 can also move towards the fixed member 53F (see reference). Figure 19 ) lateral movement.

[0175] If the user rotates tool W and shaft 533 counterclockwise (CCW), stop 532 can move toward block 534, and correspondingly, elastic member 531 can elastically deform and further stretch. Alternatively, if shaft 533 is rotated clockwise, stop 532 can also move toward block 534.

[0176] Therefore, the user can adjust the tension of the elastic member 531 using tool W. As described above, the user can change the magnitude of the force required to tilt the support arm 50 by adjusting the force applied to the elastic member 531. In other words, the user can adjust the tilt of the support arm 50 to make it looser or tighter.
