On the rotation limiting washer 62, a non-circular through hole 62b is formed. The through hole 62 b of the rotation limiting washer 62 is fixedly matched with the third hinge pin 94 so that the rotation limiting washer 62 rotates together with the third hinge pin 94 . the

The plate spring 63 has a protrusion 63 a protruding therefrom, and elastically deforms due to contact with the protrusion 62 a of the rotation limiting washer 62 . The leaf spring 63 also has a vertical extension and is fixed to the left side of the bracket 55 with a screw 67 . the

Therefore, when the monitor main body 120 is pressed forward relative to the connecting member 10, the bracket 55 coupled to the monitor main body 120 rotates forward on the first hinge holder 83 and the third hinge pin 94 at a predetermined angle until coupled to the The protrusion 62a of the rotation limiting washer 62 of the third hinge pin 94 is engaged with one side surface of the third stopper 61 formed in the left side of the bracket 55 (see FIG. 9A ). On the contrary, when the monitor main body 120 is pressed backward and forward on the connecting member 10, the bracket 55 coupled to the monitor main body 120 is rotated backward on the first hinge holder 83 and the third hinge pin 94 at a predetermined angle until The protrusion 62a of the rotation limiting washer 62 coupled to the third hinge pin 94 is engaged with the protrusion 63a of the leaf spring 63 provided in the left side of the bracket 55 (see FIG. 9B ).

Therefore, if the allowable inclination angle of the monitor main body 120 is different in different countries, by changing the size of the protrusion 62a and the third stopper 61, and by changing the position of the leaf spring 63, an appropriate monitor can be designed as required. The angle of inclination of the main body 120 of the device. the

Thus, the monitor body 120 can be folded parallel to the base member 130 by depressing the monitor body 120, when the protrusion 62a of the rotation limiting washer 62 is connected with the protrusion 63a of the leaf spring 63 fixed on the bracket 55 Stop, backward enough to elastically deform the protrusion 63a of the leaf spring 63, so that the protrusion 62a of the rotation limiting washer 62 rotates around the protrusion 63a of the leaf spring 63 and connects with the other side of the third stopper 61 (See Figure 9C and Figure 9D). the

Conversely, the folded monitor main body 120 can be restored to the original position by pressing the monitor main body 120 upward in the reverse order to the above. the

With this structure, the connection member 10 is rotated by a predetermined angle relative to the base member 130 , and the monitor main body 120 is rotated by a predetermined angle relative to the base member 130 . In addition, the connection member 10 and the monitor main body 120 may not rotate independently. For example, the monitor main body 120 is rotated at a predetermined angle relative to the base member 130 by a rotation interlock with the connection member 10 (for example, similar to the aforementioned limited tilt angle). the

To achieve the above structure, the present invention includes auxiliary link members 100 and 110 that link the rotation of the link member 10 relative to the base member 130 with the rotation of the monitor main body 120 . the

The auxiliary connection members 100 and 110 are strip-shaped and combined with the first connection support part 42 and the second connection support part 93 in parallel, respectively. Auxiliary connection accommodating portions 42c and 93d are provided in the first connection supporting portion 42 and the second connection supporting portion 93, respectively, and a plurality of pin holes 42b and 93b at a predetermined distance from each other are respectively connected to the auxiliary connection accommodating portions 42c and 93d. Corresponding. On the opposite ends of the auxiliary connecting members 100 and 110, the positions of the through holes 100a and 110a correspond to the pin holes 42b and 93b, respectively. the

Therefore, both ends of the auxiliary connection members 100 and 110 are inserted into the first connection support portion 42 and the second connection support portion 93 and the through holes 100 a and 110 a located at both ends of the auxiliary connection members 100 and 110 are respectively connected to the first connection support portion 93 . In the corresponding state of the pin holes 42b and 93b on the connection support part 42 and the second connection support part 93, the auxiliary connection elements 100 and 110 are respectively connected to the first connection support part 42 and the second connection support through a plurality of coupling pins 102. Section 93. Accordingly, the pair of auxiliary connection elements 100 and 110 move parallel to each other. the

The operation of each part of the monitor according to the present invention will be described below. the

As shown in FIGS. 7A to 7D , the connection member 10 is pressed down along the arrow "B" in FIG. 7A. Subsequently, the connecting element 10 is rotated downwards on the first hinge pin 33 and the second hinge pin 44 (see FIGS. 7B and 8B ). Here, the connection member 10 rotates very slowly due to the elasticity of the torsion spring provided on the first base hinge part 30 . the

According to the downward rotation of the connection member 10, the second connection support portion 93 provided on the upper portion 10b of the connection member 10 is rotated by a predetermined angle in the clockwise direction "C" by the auxiliary connection members 100 and 110. Here, since the rotation of the second connection support part 93 is associated with the third hinge pin 94, and the third hinge pin 94 rotates together with the bracket 55, the monitor main body 120 is inclined at a predetermined angle. Here, the inclination angle of the monitor main body 120 is relatively small. In addition, the rotation angle of the monitor main body 120 can be adjusted by changing the length and connection position of the auxiliary connection members 100 and 110 . In the above description, the reason why the third hinge pin 94 rotates together with the bracket 55 is that the third hinge pin 94 and the third pin accommodating portion 91 of the bracket 55 can be rotated by a force larger than the torque generated by the weight of the monitor main body 120. Rotate to combine. the

When the monitor is in the state shown in FIG. 7B, if the connecting element 10 is pressed down further along the arrow "D", the connecting element 10 will rotate slowly due to the elasticity of the torsion spring 35 until it is set between the first base hinge part 30 and The first stopper 51a and the second stopper 51b on the second base hinge part 40 are engaged with the protrusions 52a and 52b formed around the first protrusion accommodating part 32 and the second protrusion accommodating part 42a ( See Figure 8C). In this state, the connection element is no longer rotated downward, as shown in Figure 7C. Here, the second connection support portion 93 is rotated in the clockwise direction "E" beyond the state shown in FIG. 7B. the

When the monitor is in the state shown in FIG. 7C, in order to fold the monitor main body 120 on the base member 130, the monitor main body 120 stops between the protrusion 62a of the rotation limiting washer 62 and the leaf spring fixed on the bracket 55. The connected state of the projection 63a of the plate spring 63 should be able to press backward relative to the base member 130, enough to elastically deform the projection 63a of the leaf spring 63. The protrusion 62 a of the rotation limiting washer 62 is thus rotatable on the protrusion 63 a of the leaf spring 63 , and is connected to the other side of the third stopper 61 . Thus, the monitor body 120 is completely placed on the base member 130 (see FIGS. 7D and 9D ). the

Transitioning the monitor from the state shown in FIG. 7D (together with FIGS. 8C and 9D ) to the state shown in FIG. 7A can be done in the reverse order of the above description. the

As described above, since the monitor main body 120 is completely placed on the base member 130, the installation volume of the monitor is reduced, thereby reducing the cost of storing and transporting the monitor. the

Fig. 10 is a schematic diagram illustrating cables provided in the connection element 10 of the monitor. As shown in FIG. 10 , at the back of the connection member 10 , a cable accommodating portion 10 c is provided to accommodate the cable 153 of the cable part 150 . The first cable port 151 of the cable part 150 is fixed to the port receiving portion 133b provided in the base member 130 and the second cable port 152 thereof is connected to a part of the monitor main body 120 . Cable accommodating grooves 55b and 82 are provided in the first hinge holder 83 of the connection member 10 and the first hinge accommodating portion 81 of the bracket 55, respectively, for accommodating and guiding the cables 154 (see FIG. 6). Accordingly, the cable 153 disposed between the monitor main body 120 and the base member 130 is connected to the connection member 10 to be accommodated in the connection part 1 . the

11A and 11B are side views illustrating a monitor installed on a wall. As shown in FIGS. 11A and 11B , the base bracket 140 is fixed to the wall 160 with screws 147 . The hook 141 of the base bracket 140 is hung on the hook holder 132 a of the base member 130 . Accordingly, the monitor can be detachably installed on the wall 160 . the

12A and 12B are side views illustrating a monitor mounted on an arm stand. As shown in FIGS. 12A and 12B , the hook 141 of the base bracket 140 is inserted into the hook holder 132 a of the base member 130 , thus combining the base bracket 140 with the base member 130 . In addition, the monitor supporting portion 171 provided on the upper portion of the arm stand 170 is formed with a plurality of bracket coupling holes 173 conforming to VESA. The base member 130 combined with the base bracket 140 is placed on the monitor support part 171 . Thereafter, by passing through the bracket coupling hole 173 of the monitor supporting portion 171 and the second coupling hole 145 of the base bracket 140, the screw 172 is coupled to the bottom connection element cover 3 made on the lower connecting member cover 3 at the back of the monitor supporting portion 171. the third combination hole 3a. Therefore, the monitor can be easily mounted on various VESA-compliant arm stands, and both the connection member 10 and the base member 130 can be combined with the monitor support portion 171 of the arm stand 170 . the

In the above description, the torsion spring 35 that allows the connection member 10 to rotate slowly is provided in the first base hinge portion 30 . However, the torsion spring 35 may be provided in at least one of the first base hinge part 30 and the second base hinge part 40, respectively. In addition, a tilt limiting device 50 is provided in the second base hinge portion 40. However, the tilt limiting device 50 may be provided in at least one of the first base hinge part 30 and the second base hinge part 40 . the

In addition, a monitor angle limiting device 60 for limiting the angle adjustment of the monitor may be provided in the first monitor hinge part 80 . the

13A to 13C show a monitor with a connection part and a base element according to another embodiment of the present invention. the

As shown in Figures 13A to 13C, the monitor includes: a base element 21; a main body 22 with a screen 22a to display a picture; a connecting element 310 connecting the base element 21 to the main body 22; a base hinge 220 connecting the connecting element The lower part 310a of the connecting member 310 is rotatably connected with the base member 21; the

The connection member 310 is rotated within a predetermined angle range relative to the base member 21 . The range of the inclination angle, eg, 0° to 65°, may be determined based on regulatory requirements in each country. the

The base hinge 220 is arranged between the first fixed bracket 24 and the second fixed bracket 26, the first fixed bracket 24 and the second fixed bracket 26 are at a predetermined distance from each other, and are fixed on the base member 21 with screws 27 superior. The base hinge 220 includes a first base hinge part 230 and a second base hinge part 240 rotatably connecting two sides of the lower part 310 a of the connecting element 310 with the first fixing bracket 24 and the second fixing bracket 26 respectively. the

The first base hinge part 230 (referring to Fig. 13B and Fig. 13C) comprises: the first pin accommodating part 231 is made on the right side of the lower part 310a of the connecting element 310; on the fixed bracket 24; and the first hinge pin 233 has a first end and a second end connected with the first pin receiving portion 231 and the raised receiving portion 232, respectively. the

The first end 233a of the first hinge pin 233 is rotatably inserted into the first pin receiving part 231 with friction therebetween. The second end 233 b of the first hinge pin 233 is non-rotatably fixed in the protrusion accommodating portion 232 . Therefore, the first end 233a of the first hinge pin 233 and the first pin receiving portion 231 have a circular cross section, and the second end 233b of the first hinge pin 233 and the protrusion receiving portion 232 have a non-circular cross section. Here, the frictional force between the first hinge pin 233 and the first pin receiving portion 231 prevents the connecting member 310 from rotating downward relative to the base member 21 due to the weight of the main body 22 . the

A first torsion spring 235 is placed on the first hinge pin 233 . One end of the first torsion spring 235 is positioned at the right side of the bottom 310a of the connecting element 310, on which the first pin receiving portion 231 is formed, and the other end of the first torsion spring 235 is positioned at the first fixed bracket 24. the

The first torsion spring 235 provides elastic force in the direction opposite to the downward rotation of the connecting member 30 relative to the base member 21 . The elastic force provided by the first torsion spring 235 is almost equal to the torque in the base hinge due to the weight of the main body 22 . In addition, due to the frictional force between the first hinge pin 233 provided in the first base hinge part 230 and the first pin accommodating part 231 , and the contact between the second hinge pin 244 provided in the second base hinge part 240 and The upward and downward rotation states of the connection member 310 are prevented by friction between the second pin accommodating portion 241 (to be described later). Therefore, in order to rotate the connection member 310 upward or downward relative to the base member 21 , the connection member 310 is pressed using a force greater than the frictional force of the first base hinge part 230 and the second base hinge part 240 . the

The second base hinge part 240 (referring to Fig. 13B and Fig. 13C) comprises: the second pin accommodating part 241, is made on the left side of the lower part 310a of connecting element 310; The frame 26 is combined to form a spline receiving portion 242a therein; and a second hinge pin 244 having a first end and a second end connected to the second pin receiving portion 241 and the spline receiving portion 242a, respectively. the

The first end 244a of the second hinge pin 244 has a circular cross section and is rotatably inserted into the second pin receiving part 241 with a predetermined frictional force therebetween. The second end 244b of the second hinge pin 244 is non-rotatably fixed in the spline receiving portion 242a. Here, the second end 244b of the second hinge pin 244 is splined to match with the spline receiving portion 242a of the first connecting support portion 242 . Here, the frictional force between the second hinge pin 244 and the second pin receiving portion 241 prevents the connecting member 310 from rotating downwardly relative to the base member due to the weight of the main body 22 . the

A first torsion spring 235 is provided in the first base hinge part 230 to hold the connection element 310 in place, and corresponding to the first torsion spring 235, a rotation angle limiting device 250 is placed on the second base hinge part 240 , used to limit the rotation of the connection element 310 relative to the base element 21 within a predetermined range. The rotation angle limiting device 250 is designed to suitably comply with the rotation angle regulations of VESA. the

The rotation angle limiting device 250 (see FIGS. 13C and 18A ) includes a pair of first stoppers 251 formed around the second pin accommodating portion 241 on the left side of the lower portion 310a of the connecting member 310 to face each other. The rotation angle limiting device 250 also includes a first rotation limiting washer 252 placed on the second hinge pin 244, including a pair of protrusions 252a, which can be selectively engaged with the first stopper 251 according to the rotation direction of the connecting member 310. . the

A non-circular through hole 252b is formed on the first rotation limiting washer 252 . Accordingly, the second hinge pin 244 is inserted into the through hole 252 b of the first rotation limiting washer 252 . Therefore, if the connecting member 310 is pressed downward relative to the base member 21, the connecting member 310 rotatably combined with the first hinge pin 233 and the second hinge pin 244 is rotated downward until the first stopper 251 is in the downward direction. The lower rotation limit position is engaged with the protrusion 252a of the first rotation limiting washer 252 (see FIG. 18C). the

On the contrary, if the connection element 310 is pressed upward from the base element 21, the connection element 310 is rotated upward by the first hinge pin 233 and the second hinge pin 244 until the first stopper 251 is at the upward rotation limit position and the first rotation limit. The projection 252a of the washer 252 engages (see FIG. 18A). the

Therefore, the inclination angle of the connection member 310 relative to the base member 21 can be determined by the rotation angle limiting device 250, and therefore, if the rotation angle of the connection member 310 is different in different countries, it can be determined by changing the protrusion 252a and the stopper 251 According to the size of the need to design an appropriate rotation angle. the

A monitor hinge 270 (see FIG. 13A ) is provided on the upper portion 310b of the connection member 310, and the monitor main body 22 can rotate relative to the connection member 310 within a predetermined angle range through the hinge 70. The range of the rotation angle, for example, 5° to 30° may be appropriately determined based on regulatory requirements in different countries. the

The monitor hinge 270 includes a first monitor hinge part 280 and a second monitor hinge part 290 rotatably combined with opposite edges of a bracket 255 fixed to the monitor main body 22 by screws 257 . the

The first monitor hinge part 280 (referring to Fig. 13B and Fig. 13C) comprises: the 3rd pin accommodating part 281, is made in the right side of bracket 255; Right side; the third hinge pin 283 , to be inserted into the third pin accommodating portion 281 and the fourth pin accommodating portion 282 . Here, the first end 283a of the third hinge pin 283 is rotatably inserted into the third pin receiving part 281 so that the main body 22 can be rotated. The second end 283b of the third hinge pin 283 is fixedly press-fit connected into the fourth pin receiving portion 282 . the

The second monitor hinge part 290 (referring to Fig. 13B and Fig. 13C) comprises: the fifth pin accommodating part 291, is made in the left side of bracket 255; Left side; the second connection support portion 293 rotatably inserted into the sixth pin accommodating portion 292 from the outside of the upper portion 310 b of the connection member 310 . The second monitor hinge portion 290 also includes a fourth hinge pin 294 having a first end 294a inserted into the fifth pin accommodating portion 291 of the bracket 255 and a spline with the second connecting support portion 293. The key receiving portion 293a mates with the second end 294b. the

Like the first hinge pin 233, the second hinge pin 244, and the third hinge pin 283, the first end 294a of the fourth hinge pin 294 is rotatably inserted into a fifth pin accommodating portion 291 formed on the bracket 55, between which have a predetermined friction. The second end 294b of the fourth hinge pin 294 is non-rotatably matched with the spline receiving portion 293a of the second connection support portion 293 . In addition, the second connection support part 293 combined with the second end 294 b of the fourth hinge pin 294 is also rotatably inserted into the sixth pin receiving part 292 . The hinge joint between the second connection support part 293 and the sixth pin receiving part 292 is connected with auxiliary connection members 2100 and 2110 (to be described later). Here, the frictional force between the fourth hinge pin 294 and the main body 22 prevents the connecting member 310 from rotating downward relative to the base member 21 due to the weight of the main body 22 . Therefore, the frictional force should be greater than the torque due to the weight of the body 22 . the

In the second monitor hinge part 290, as the rotation angle limiting device 250 limits the rotation of the connection member relative to the base member 21 within a predetermined angle range, a monitor angle limiting device 260 is provided for holding the main body 22 relative to the other. The rotation of the connecting member 310 is limited within a predetermined angular range. The monitor angle limiting device 260 is designed to be suitable for the rotation angle of the main body 22 relative to the connecting member 310 . the

The monitor angle limiting device 260 (see FIG. 13C ) includes: an arc-shaped second stopper 261 protruding from the left side of the bracket 255 adjacent to the fifth pin accommodating portion 291; a second rotation limiting washer 262 placed on The fourth hinge pin 294 has a protrusion 262a, which is connected with the second stopper 261 according to the rotation direction of the main body 22; and a third stopper 263, which is combined with the left side of the bracket 55 and locked on the protrusion 262a. Or released from the protrusion 262a. the

A non-circular through hole 262 b is formed on the second rotation limiting washer 262 . The through hole 262 b of the second rotation limiting washer 262 is fixedly matched with the fourth hinge pin 294 , so that the second rotation limiting washer 262 rotates together with the fourth hinge pin 294 . the

The third stopper 263 is rotatably connected to the left side of the support portion using a screw 267 adjacent to the fifth pin receiving portion 291 . The third stopper 263 is used to adjust the angle of the main body 22 when the monitor is in use, and to fold the main body 22 on the base member 21 when the monitor is packaged. the

A second torsion spring 265 is provided between the left side of the bracket 255 and the third stopper 263 . Adopting the second torsion spring 265 (will be explained in more detail below) is to be used for returning the third stopper 263 to the initial position. the

A spacer 298 is provided between the second connection support portion 293 and the second rotation limiting washer 262 . The spacer 298 is used to maintain a predetermined distance between the second connection support portion 293 and the second rotation limiting washer 262 . the

Therefore, if the main body 22 is vertically compressed relative to the connecting member 310 sufficiently to exceed the friction force between the fourth hinge pin 294 and the bracket 255, the main body rotates on the third hinge pin 283 and the fourth hinge pin 294 respectively. The main body 22 can be rotated until the protrusion 262a of the second rotation limiting washer 262 is connected with one side of the second stopper 261 or the first end 263a of the third stopper 263 (see FIG. 19A or FIG. 19B ). Therefore, if the allowable rotation angle of the main body 22 is different in different countries, by changing the size of the protrusion 262a and the second stopper 261 and by changing the position of the third stopper 263, an appropriate rotation angle can be designed as required. The angle of rotation of the main body 22 . the

In addition, in order to fold the main body on the base member 21 in a parallel position, the main body 22 is rotated until the protrusion 262a engages with the other side of the second stopper 261 (see FIG. 19D ), but not with the third stopper. The first end 263a of the tool 263 is engaged (see the dashed line in FIG. 19C). the

In order to return the third stopper 263 to the original position, a second torsion spring is provided on the third stopper 263 . Therefore, after the protrusion 262a passes the third stopper 263 and the third stopper 263 is rotated on the screw 267 by pushing the second end 263b (see the rotation from the solid line to the dashed line in FIG. 19C ), if the third stopper The second end 263 b of the stopper 263 is released by being pushed, and the third stopper 263 returns to the original position due to the elastic force of the second torsion spring 265 . the

With the above structure, the connection member 310 is rotated by a predetermined angle relative to the base member 21 , and the main body 22 is rotated by a predetermined angle relative to the connection member 310 . the

In addition, the connecting element 310 and the main body 22 may not rotate independently. That is, the main body 22 can be rotated at a predetermined angle by matching the rotation of the connection member 310 relative to the base member 21 . the

In order to realize the above structure, the present invention further includes auxiliary connecting elements 2100 and 2110 for linking the rotation of the connecting element 310 relative to the base element 21 with the rotation of the main body 22 . the

The auxiliary connection members 2100 and 2110 are bar-shaped and coupled to the first connection support part 242 and the second connection support part 293 in parallel, respectively. A plurality of pin holes are provided in each of the first connection support part 242 and the second connection support part 293 at a predetermined distance apart. The second connection support part 293 is provided with a pin hole 293a. In particular, pin holes (not shown) of the first connection support portion 242 correspond to the pin holes 26 b formed on the second fixing bracket 26 . Both ends of the auxiliary connection elements 2100 and 2110 are formed with through holes 2100a and 2110a corresponding to the pin holes 296b and 26b, respectively. the

Therefore, when the through holes 2100a and 2110a made at both ends of the auxiliary connection members 2100 and 2110 are respectively connected with the pin holes made on the first connection support part 242 and the second connection support part 293 and at the second fixing bracket In the corresponding state of the pin holes 26b made on the 26, the auxiliary connection elements 2100 and 2110 are respectively connected to the first connection support part 242 and the second connection support part 293 through a plurality of connection fixing pins 2120. Accordingly, the pair of auxiliary connection elements 2100 and 2110 move parallel to each other. the

The operation of the monitor according to the present invention will be described below. the

When the monitor is in the state shown in FIG. 14 (together with FIGS. 18A and 19A ), the connection member 310 is pressed down along the arrow "B" in FIG. 14 . Subsequently, the connecting element 310 is rotated downward on the first hinge pin 233 and the second hinge pin 244 (see FIGS. 15 and 18B ). Due to the elasticity of the first torsion spring 235 provided on the first base hinge part 230, the connection member 310 rotates very slowly. the

According to the downward rotation of the connection member 310, the second connection support portion 293 provided on the upper portion 310b of the connection member 310 is rotated by a predetermined angle in the clockwise direction "C" by the auxiliary connection members 2100 and 2110, as shown in FIG. Here, the rotation of the second connection support part 293 rotates the third hinge pin 283, and the fourth hinge pin 294 and the bracket 255 are interconnected by friction force therebetween, so the main body 22 also rotates by a predetermined angle. The rotation angle of the main body 22 is relatively small. In addition, by changing the length and connection position of the auxiliary connection members 2100 and 2110, the rotation angle of the main body 22 can be adjusted. the

When the monitor is in the state shown in Figure 15, if the connecting element 310 is pressed down further along the arrow "D", the connecting element 310 will slowly rotate due to the elastic force of the torsion spring 235 until it is set on the second base hinge part 240 One of the first stoppers 251 on the top engages with the protrusion 252a of the first rotation limiting washer 252 (see FIG. 18C ). Here, the second connection support portion 293 is rotated in the clockwise direction "E" beyond the state shown in FIG. 15 . the

When the monitor is in the state shown in Figure 16, in order to fold the main body 22 on the base element 21, the protrusion 262a passes through the first end 263a of the third stopper 263, and simultaneously pushes its second end 263b to make The third stopper 263 rotates on the screw 267 . As shown in FIG. 19C, the third stopper 263 moves from the solid line to the broken line. the
