Hereinafter, embodiments of the present general inventive concept will be described in detail with reference to related drawings.

Illustrated in FIG. 1 is a perspective view of a front surface of a dual display unit having a supporting device 100 (see FIG. 2 ) according to the present general inventive concept.

The dual display unit includes a main display unit 10 and an auxiliary display unit 20 . The auxiliary display unit 20 is installed on the side surface 14 of the main display unit 10 .

The stand 12 is mounted on the lower part of the main display unit 10 for supporting the main display unit 10 on a table or workbench (not shown), so that the main display unit 10 faces the user (not shown). The stand 12 is not simply used to support the main display unit 10 , it also controls various postures of the main display unit 10 , such as horizontal rotation operation and vertical tilt operation.

The main screen 11 and the auxiliary screen 21 are respectively disposed on the main front surface 15 of the main display unit 10 and the auxiliary front surface 24 of the auxiliary display unit 20 to display images. In this case, the screen 11 and the screen 21 may be formed of a liquid crystal display (LCD) or a plasma display panel (PDP). The auxiliary screen 21 on the auxiliary display unit 20 may be formed smaller than the main screen 11 of the main display unit 10 .

As shown in FIG. 2 , the support device 100 is attached to the main rear surface 16 of the main display unit 10 and the auxiliary rear surface 25 of the auxiliary display unit 20 . The supporting device 100 adjusts the distance between the auxiliary display unit 20 and the main display unit 10 while also supporting the auxiliary display unit 20 when the posture of the auxiliary display unit 20 is changed or is firmly fixed. The supporting device 100 includes a first supporting part 110 installed on the main display unit 10 and a second supporting part 120 installed on the auxiliary display unit 20 . The second supporting part 120 is slidably connected to the first supporting part 110 so as to adjust the length of the supporting device 100 . Thus, the distance between the auxiliary display unit 20 and the main display unit 10 can be adjusted by adjusting the extendable length of the supporting device 100 .

Further, the first installation frame 130 and the second installation frame 140 are respectively fixed on the main display unit 10 and the auxiliary display unit 20 to install the supporting device 100 on the main display unit 10 and the auxiliary display unit 20 . The first supporting part 110 and the second supporting part 120 are rotatably connected with the first mounting frame 130 and the second mounting frame 140 respectively. Therefore, the auxiliary display unit 20 can not only be moved to the upper or side of the main display unit 10, but also can be arranged in a landscape view or a portrait view by being rotated.

The configuration of the support device 100 will be described in detail below with reference to FIGS. 3 and 4 .

Further, mounting frames 130 and 140 are mounted on the main rear surface 16 of the main display unit 10 and the auxiliary rear surface 25 of the auxiliary display unit 20, respectively. In general, four holes conforming to the Video Electronics Standards Association (VESA) standard are arranged in a rectangular shape on the rear surface of the display unit. Main display unit mounting holes 13 and auxiliary display unit mounting holes 22 conforming to Video Electronics Standards Association (VESA) standards are respectively provided on the main rear surface 16 of the main display unit 10 and the auxiliary rear surface 25 of the auxiliary display unit 20 . And, a first frame installation hole 130 a and a second frame installation hole 142 are provided at corresponding positions on the installation frames 130 and 140 , respectively. Accordingly, the mounting frames 130 and 140 are respectively fixed on the main display unit 10 and the auxiliary display unit 20 through the first frame mounting hole 130a and the second frame mounting hole 142 .

The main frame shaft hole 130b and the auxiliary frame shaft hole 140a are provided on the mounting frames 130 and 140, respectively, and are used for rotation of the first supporting part 110 and the second supporting part 120, respectively. In the central area including the shaft holes 130b and 140a, protrusions 131 and 141 are respectively formed on the first mounting frame 130 and the second mounting frame 140, and in order to minimize the frictional contact during rotation, the two protrusions are opposite to the main frame shaft holes. 130b and the auxiliary frame shaft hole 140a protrude in the axial direction.

In addition, a main support shaft hole 110 a and an auxiliary support shaft hole 120 a are provided on the first support part 110 and the second support part 120 , respectively. The first fastening part 134 and the second fastening part 128, both of which are formed in the shape of a screw, pass through the main support shaft hole 110a of the first support part 110 and the auxiliary support shaft hole 120a of the second support part 120, and are respectively connected with the second support shaft hole 110a. The shaft hole 130b of the main frame of the first installation frame 130 is connected with the shaft hole 140a of the auxiliary frame of the second installation frame 140 .

Four friction rings 135, 136, 137 and 138 are installed between the first support member 110 and the first installation frame 130 so that the first support member 110 can rotate at an appropriate speed. In addition, the friction rings 135 , 136 , 137 and 138 stop the first support member 110 whenever the first support member 110 turns through 90 degrees. Also, three friction rings 125 , 126 and 127 are installed between the second support member 120 and the second installation frame 140 . The functions of the friction rings 125 , 126 and 127 are the same as those of the friction rings installed on the first support member 110 .

Meanwhile, a first rotation limiting protrusion 132 is formed on the first mounting frame 130 to limit a rotation range of the first support member 110 , and a second rotation limiting protrusion 110 b is installed on the first support member 110 . The first rotation restricting protrusion 132 and the second rotation restricting protrusion 110b are rotation restricting members for forming a contact surface according to the rotation phase of the first support member 110 . The first rotation restricting protrusion 132 is disposed on an opposite side of the main frame shaft hole 130b of the first mounting frame 130, and the second rotation restricting protrusion 110b is formed at one side of the main support shaft hole 110a. Therefore, the rotation range of the first support member 110 is limited to about 180 degrees. Thus, the auxiliary display unit 20 can be fixed at the opposite side of the main display unit 10 (the side opposite to the side surface 14 as shown in FIG. 1 ) without moving to the lower end of the main display unit 10, if desired.

Then, for the coupling relationship between the first support part 110 and the second support part 120 , a guide rail 113 is formed at one side of the first support part 110 to guide the sliding of the second support part 120 . Guide members 115 and 116 forming a contact surface with the second support member 120 are installed on the inner side 114 of each of the corresponding guide rails 113 . The guide rail 113 accommodates and supports the guide members 115 and 116 . The guide parts 115 and 116 slidably support the second support part 120 and provide an appropriate frictional force in sliding of the second support part 120 to adjust the moving speed when the second support part 120 is extended or contracted.

The fixing protrusions 112 a and 112 b are provided on the first support member 110 to restrain the guide members 115 and 116 when the second support member 120 moves forward or backward, thereby maintaining the structural integrity of the support device 100 . Fixing grooves 115a and 116a are provided on the guide members 115 and 116 at positions corresponding to the fixing protrusions 112a and 112b. In this case, the configurations of the fixing protrusions 112 a and 112 b and the fixing grooves 115 a and 116 a may be changed to change a moving range of the guide parts 115 and 116 relative to the first supporting part 110 .

A pin hole 120d (see FIG. 3 ) is provided at an end portion opposite to an end portion of the second support member 120 on which the auxiliary display unit 20 is mounted. In other words, the pin hole 120 d is provided near the end portion closer to the second support member 120 than to the first support member 110 . The anti-separation pin 119 (see FIG. 3 ) is connected to the pin hole 120d. The anti-separation pin 119 is connected to the pin hole 120d in a state where the end of the second support member 120 passes through the rail portions 115a and 116a on the guide members 115 and 116 and moves to the opposite sides. Therefore, when the second support member 120 moves outward in the state where the anti-separation pin 119 is connected to the pin hole 120d, if the second support member 120 moves out of the set moving range, the anti-separation pin 119 is held by the rail portion. The ends of 115a and 116a are blocked and can no longer move, thus preventing separation.

The first support member 110 has positioning slots 111 a and 111 b for establishing a stop position when the second support member 120 slides. A stopper 117 having a positioning protrusion 117b adapted to engage with the positioning grooves 111a and 111b is installed on the second support member 120 .

The stopper 117 is fixed to the second support member 120 by connecting the fastening member 118 to the stopper installation hole 117 a and the second support installation hole 120 c provided on the stopper 117 and the second support member 120 , respectively. In a state where the second support part 120 is connected to the first support part 110 , the stopper 117 is fixed to the second support part 120 . A through hole 120b is provided on the second support member 120 such that the positioning protrusion 117b passes through the through hole 120b to protrude to the opposite sides. The positioning protrusion 117b is provided at the center of the plate-shaped stopper 117 and elastically supported by the stopper 117 of this shape.

A pair of positioning grooves 111a and 111b may be disposed on the inner surface of the first support member 110 and spaced a certain distance from each other. The positioning grooves 111 a and 111 b are provided at two positions of the positioning protrusion 117 b on the inner surface of the first support member 110 in a state where the auxiliary display unit 20 is placed on the upper side or the opposite side of the main display unit 10 . Therefore, when the auxiliary display unit 20 is placed on the upper side or the opposite side of the main display unit 10 during the movement of the auxiliary display unit 20, the positioning protrusion 117b is either connected to the positioning groove 111a or to the positioning groove 111b, so that The length of the support device 100 is securely fixed.

In addition, the hinge part 121 is provided on the second support member 120 so that the screen of the auxiliary display unit 20 can be rotated and tilted while forming a certain tilt angle with respect to the screen of the main display unit 10 . In this case, the hinge portion 121 is preferably disposed inwardly from the outer boundary of the auxiliary display unit 20 in a state where the second supporting member 120 is mounted on the auxiliary display unit 20 .

In addition, when the support device 100 is installed, a bent portion 122 is formed on the second support member 120 to bend forward from the main display unit 10 . Considering that the auxiliary display unit 20 and the main display unit 10 have different thicknesses, the curved portion 122 can make the auxiliary display unit 20 and the main display unit 10 be positioned on the same plane.

According to the above structure, as shown in FIG. 5 , the auxiliary display unit 20 can be rotated by the hinge portion 121 to perform a tilting operation, so that its front surface 24 can face the side, and then the main display unit 10 and the auxiliary display can be Unit 20 is set at 90 degrees.

In addition, as shown in FIG. 6 , when the supporting device 100 is turned upward, the auxiliary display unit 20 is on the upper side of the main display unit 10 . Also, in this case, the auxiliary display unit 20 can be set in a landscape view or a portrait view by being rotated.

The auxiliary display unit 20 can be easily separated from the support device 100 and can be used as an independent display unit after separation.

FIG. 7 is an exploded perspective view of a supporting device 200 according to another embodiment of the present general inventive concept.

The support device 200 includes: a support member 210 connected between the main display unit 10 (see FIG. 3 ) and the auxiliary display unit 20 (see FIG. 3 ), and is slidably connected to the support member 210 and guides the direction of the support member 210. The sliding unit 220 moves forward or backward to adjust the distance between the auxiliary display unit 20 and the main display unit 10 .

One end of the support member 210 is rotatably connected to the rear surface 25 of the auxiliary display unit 20 in the same manner as in the above-described embodiment. However, while in the embodiments described above the two support members 110 and 120 are slidably connected to each other for length adjustment, a design choice in this embodiment is whether the ability to adjust the length of the support member 210 is configured . Alternatively, the distance between the main display unit 10 and the auxiliary display unit 20 can be adjusted by sliding along with the sliding unit 220 attached to the rear surface 16 of the main display unit 10 .

The slide unit 220 includes a turntable 221 forming a base and a guide roller 222 installed on the turntable 221 .

The turntable 221 is rotatably connected to the main display unit 10 . For this purpose, the center of the turntable 221 is provided with a shaft hole 221a.

In the same manner as in the above-described embodiments, the first mounting frame 130 is mounted on the main display unit 10 through the first bracket mounting hole 130a conforming to the Video Electronics Standards Association (VESA) standard. A shaft hole 130 b and a protruding portion 131 are also formed on the first mounting frame 130 .

The first fastening member 134 is connected back and forth between the first mounting frame 130 and the turntable 221 through the shaft hole 130b and the shaft hole 221a. Friction rings 135 and 136 and washers 137 and 138 are inserted between the first fastening member 134 and the turntable 221 .

In addition, first rotation limiting protrusions 132 and 133 are formed on the first mounting frame 130 , and two second rotation limiting protrusions 224 and 225 are formed on one side of the turntable 221 .

The first rotation limiting protrusions 132 and 133 are arranged at a central angle of about 180 degrees with respect to the shaft hole. Second rotation limiting protrusions 224 and 225 are provided on one surface of the turntable 221 to be spaced apart from each other. Therefore, as shown in FIG. 7, when the support member 210 faces the left side shown in FIG. 7, the first rotation limiting protrusion 132 on the left side contacts with the second rotation limiting protrusion 224 positioned at the lower part to limit sliding. Rotation of unit 220. On the other hand, when the supporting member 210 faces the right side, the first rotation limiting protrusion 133 on the right side comes into contact with the other second rotation limiting protrusion 225 to limit the rotation. Accordingly, the auxiliary display unit 20 may remain in a fixed state while being placed on the opposite side of the main display unit 10 as shown.

The guide rollers 222 installed on the turntable 221 may be arranged in a rectangular shape as shown. The two guide rollers 222 arranged on the upper side of the turntable 221 support the upper part of the support member 210, and the two guide rollers 222 arranged on the lower side of the turntable 221 support the lower part of the support member 210, thereby guiding the support member 210 in the longitudinal direction. direction to move forward or backward.

A guide groove 210 a is longitudinally formed on the support member 210 , and a sliding protrusion 223 connected to the guide groove 210 a is formed on the turntable 221 . The guide groove 210a limits the moving range of the support member 210 . When the support member 210 moves forward or backward along the guide roller 222, the slide protrusion 223 moves into the groove 210a while being aligned in the guide groove 210a. After that, when the sliding protrusion 223 comes into contact with the end of the guide groove 210a, the sliding protrusion provides a braking force against the movement of the supporting member 210, stopping it from moving. Therefore, the moving range of the support member 210 is determined by the length of the guide groove 210a.

In this case, the sliding protrusion 223 may be formed as a single body with the turntable 221 , or may be processed and assembled separately from the turntable 221 .

In addition, the rack 211 and the gear 226 are mounted on the support member 210 and the turntable 221, respectively. The rack gear 211 is aligned for movement in the longitudinal direction of the support member 210 in the same manner as the guide groove 210a. Since the rack 211 operates within the moving range of the supporting member 210, the length of the bracket 211 is adapted to the length of the guide groove 210a.

The gear 226 installed on the turntable 221 is engaged with the rack 211 to rotate as the rack 211 moves. In order to separate the gear 226 from the rack 211 while the support member 210 moves forward or backward, the positions of the rack 211 and the gear 226 are determined for the range of movement of the support member 210, and this range is determined by the guide groove 210a and the sliding protrusion. 223 decided. The rack 211 and the gear 226 are arranged to adjust the translation speed of the support member 210 by adjusting the rotational resistance of the gear 226 applied to the linear movement of the rack 211 . In this case, the rotation resistance of the gear 226 can be increased by connecting an additional damper (not shown) or applying a high-viscosity fluid on the shaft of the gear 226 to increase the rotational friction.

As in the above-described embodiments, the hinge portion 210b is provided on the support member 210 to allow the auxiliary display unit 20 to be tilted in the front-rear direction. In addition, the connection structure between the support member 210 and the auxiliary display unit 20 is also formed as in the above-described embodiment. Accordingly, the second mounting frame 140 having the shaft hole 140 a is connected to the auxiliary display unit 20 .
