1. Field of the Invention
The present invention relates to a monitor, and more particularly, to a monitor having a monitor main body and a base member supporting the monitor main body.
2. Description of the Related Art
Generally, a monitor includes a monitor main body displaying a picture thereon, a base member supporting the monitor main body, and a link member allowing the monitor main body to be forward and backward tilted and adjusting a height of the monitor main body with respect to the base member.
On the other hand, according to a wide and rapid spread of computer systems, demands on monitors are also rapidly increasing. In relation to the increased demands on the monitors, there has been provided an arm stand to support a monitor, which is manufactured separately from the monitor and combined to the monitor, to thereby meet various users preferences. Further, a combining structure of the monitor and the arm stand has been regulated by VESA (video electronic standard association).
As shown in
A lower part of the link member 210 is forward and backward tiltably combined to the base member 201 using a pair of fixing brackets 204 and 206, and an upper part of the link member 210 is fixed to the monitor main body 202.
Thus, along a direction of an arrow “A” in
Contrary to the monitor shown in
However, in the conventional monitor, because the height of the monitor main body 202 is adjusted by rotating the link member 210 relative to the base member 201 and a size of the link member 210 should depend on a size of the base member 201, an allowable height adjustment of the monitor main body 202 is relatively small.
Further, in the conventional monitor, because the monitor main body 202 is not folded to the base member 201, a packing volume of the monitor cannot be decreased, thereby increasing costs for keeping and carrying the monitor.
Further, in the conventional monitor, because the base member 201 must be laid on only the horizontal plane, it is impossible to install the monitor onto an inclined plane, such as a wall, the arm stand for the monitor, etc.
Accordingly, it is an aspect of the present invention to provide a monitor in which an allowable height adjustment of a monitor main body is relatively large, and costs for keeping and carrying the monitor can be decreased by decreasing a packing volume of the monitor.
It is another aspect of the present invention to provide a monitor, in which a height of a monitor main body can be adjusted without changing a tilting angle of the monitor main body, and a tilting angle of the monitor main body with respective to a base member can be properly adjusted.
It is still another aspect of the present invention to provide a monitor, in which a base member is detachably combined with a base bracket and can be installed onto an inclined plane, such as a wall, an arm stand, etc., and particularly, easily installed onto various arm stands according to a VESA (video electronic standard association) regulation.

These and/or other aspects and advantages of the present invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompany drawings of which:
Reference will now be made in detail to the embodiment of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiment is described below in order to explain the present invention by referring to the figures.
Generally, a monitor includes a monitor main body displaying a picture thereon, and a base member supporting the monitor main body and laid on a predetermined inclined plane, such as a wall, a table, etc.
Recently, the monitor is being made of an LCD (liquid crystal display), so that the monitor can have a relatively thin monitor main body even if a displaying area thereof is enlarged. Hereinbelow, the monitor made of an LCD panel will be exemplarily described.
As shown in
On a front of the monitor main body 10 is provided a screen (not shown), and on a rear thereof are fastened the first and second monitor brackets 80 and 90 with screws 15, wherein the first and second monitor brackets 80 and 90 are spaced-apart from each other and rotatably combined to the upper link member 100.
The base member 20 is laid on a horizontal plane, such as a table, and supports the monitor main body 10. On the base member 20 are fastened the first and second base brackets 30 and 40 with the screws 15.
The base hinge 60 includes first and second base hinge parts 61 and 71 rotatably connecting first lower opposite parts 50a of the lower link member 50 to the first and second base brackets 30 and 40, respectively.
The lower link member 50 is rectangular and includes the first lower opposite parts 50a rotatably connected by the first and second base hinge parts 61 and 71 to the first and second base brackets 30 and 40 fastened to the base member 20, and first upper opposite parts 50b rotatably connected by first and second link hinge parts 111 and 121 (to be described later) to second lower opposite parts 100a of the upper link member 100.
The first base hinge part 61 includes a first hinge pin 63 formed with a first end 63a having a circular cross section and a second end 63b having a noncircular cross section, a first pin accommodating part 52 formed on one of the first lower opposite parts 50a of the lower link member 50 to accommodate the first end 63a of the first hinge pin 63 therein to be rotatably combined with the first hinge pin 63, a first pin holding part 33 formed on one side of the first base bracket 30 and fitting the second end 63b of the first hinge pin 63 therein, and a first friction spring 65 interposed between the first pin accommodating part 52 and the first end 63a of the first hinge pin 63 to resist (restrict) a rotation of the first hinge pin 63. Further, in the one side of the first base bracket 30 is formed a spring supporting part 32, and a torsion spring 67 is inserted around the spring supporting part 32 to be elastically biased in an opposite direction to a downward rotation of the lower link member 50 relative to the base member 20.
The first end 63a of the first hinge pin 63 is inserted in the first friction spring 65, so that friction is produced when the first hinge pin 63 is rotated, and it is possible that the friction is stronger than a torque due to a weight of the monitor main body 10 rotating about an axis of the first hinge pin 63. Further, the first friction spring 65 is matched with (fixedly inserted into) the first pin accommodating part 52 not to rotate coincidentally with the first hinge pin 63.
The second end 63b of the first hinge pin 63 is fitted in the first pin holding part 33 formed on an end of the spring supporting part 32 of the first base bracket 30, so that the first hinge pin 63 does not rotate relative to the first base bracket 30.
The torsion spring 67 is inserted around the spring supporting part 32 of the first base bracket 30 and has one end coupled to the one first lower opposite part 50a of the lower link member 50 and the other end coupled to the first base bracket 30. Here, the torsion spring 67 provides elasticity to the lower link member 50 to be biased in an opposite direction to a downward rotation of the lower link member 50 relative to the base member 20. Further, the elasticity of the torsion spring 67 is approximately equal to the torque due to the weight of the monitor main body 10 rotating about the axis of the first hinge pin 63. Here, the weight of the monitor main body 10 is offset against the elasticity of the torsion spring 67, so that a user can easily rotate the lower link member 50 relative to the base member 20. Further, a user can easily rotate the lower link member 50 relative to the base member 20 with a force large enough to overcome the friction between the first friction spring 65 and the first hinge pin 63.
The second base hinge part 71 includes a second hinge pin 73 formed with a first end 73a having a circular cross section and a second end 73b having a noncircular cross section, a second pin accommodating part 53 formed on the other one of the first lower opposite parts 50a of the lower link member 50 to accommodate the first end 73a of the second hinge pin 73 therein so as to be rotatably combined with the second hinge pin 73, a second pin holding part 43 formed on one side of the second base bracket 40 and fitting the second end 73b of the second hinge pin 73 therein, and a rotation restricting part 75 restricting a rotation of the lower link member 50 relative to the base member 20 within a first predetermined angle range.
The second hinge pin 73 has the same shape as the first hinge pin 63, and the first end 73a of the second hinge pin 73 is rotatably inserted in the second pin accommodating part 53 formed on the other first lower opposite part 50a of the lower link member 50. Further, the second end 73b of the second hinge pin 73 is fitted in the second pin holding part 43 formed on the second base bracket 40, so that the second hinge pin 73 does not rotate relative to the second base bracket 40.
The rotation restricting part 75 includes a pair of first stoppers 76 and a pair of first projections 77. Here, the first stoppers 76 are formed by cutting a fan shaped groove from the other first lower opposite part 50a of the lower link member 50 and disposed around the second pin accommodating part 53 to face the second base bracket 40. The first projections 77 are provided around the second pin holding part 43 formed on the one side of the second base bracket 40 and are selectively stopped by one of the first stoppers 76 according to a rotating direction of the lower link member 50.
Here, the lower link member 50 is rotatably combined to the second base bracket 40, which is fastened onto the base member 20, at its rotatable angle relative to the base member 20 to be restricted within a predetermined range. For instance, the rotatable angle of the lower link member 50 ranges from 0° to 90°. Here, the rotatable angle is determined according to a design of the first stoppers 76 and the first projections 77, so that the rotatable angle can be changed by modifying the first stoppers 76 and the first projections 77, e.g., adjusting a relative position between the first stoppers 76 and the first projections 77 (refer to
With this configuration, an operation of the lower link member 50 hinging on the base hinge 60 is as follows. First, when the lower link member 50 in a state shown in
Thus, the user can easily rotate the lower link member 50 relative to the base member 20 with the same force regardless of the upward or downward rotating direction.
The link hinge 110 includes the first and second link hinge parts 111 and 121 to rotatably connect the first upper opposite parts 50b of the lower link member 50 with second lower opposite parts 100a of the upper link member 100.

The first link hinge part 111 includes a first hinge axle 113 combined to one of the second lower opposite parts 100a of the upper link member 100 and one of the first upper opposite parts 50b of the lower link member 50 so as to rotatably connect the one second lower opposite part 100a of the upper link member 100 with the one first upper opposite part 50b of the lower link member 50, a first axle accommodating part 55 protruding from the one first upper opposite part 50b of the lower link member 50 to receive the first hinge axle 113 rotatable therethrough, and a first axle holding part 102 formed on the one second lower opposite part 100a of the upper link member 100 and combined with a first end of the first hinge axle 113 by first screws 104 so as to rotate coincidentally with the upper link member 100.
The first hinge axle 113 includes the first end combined to the first axle holding part 102 formed on the one second lower opposite part 100a of the upper link member 100 by the first screws 104 and rotating coincidentally with the upper link member 100, and a second end formed with an first auxiliary link combination part 115 accommodating a pair of first auxiliary link members 160. The first hinge axle 113 is rotatably inserted in the first axle accommodating part 55 formed on the one first upper opposite part 50b of the lower link member 50. Hence, the one second lower opposite part 100a of the upper link member 100 is rotated relative to the lower link member 50 about an axis of the first hinge axle 113.
The second link hinge part 121 includes a second hinge axle 123 combined to the other one of the second lower opposite parts 100a of the upper link member 100 and the other first upper opposite part 50b of the lower link member 50 so as to rotatably connect the other second lower opposite part 100a of the upper link member 100 with the other first upper opposite part 50b of the lower link member 50, a second axle accommodating part 56 protruding from the other first upper opposite part 50b of the lower link member 50 to receive the second hinge axle 123 rotatable therethrough, and a second axle combining part 103 formed on the other second lower opposite part 100a of the upper link member 100 to accommodate the second hinge axle 123 rotatable therethrough.
The second hinge axle 123 includes a first end formed with a second auxiliary link combination part 125 accommodating a pair of second auxiliary link members 170 (to be described later), and a second end combined with a third auxiliary link combination part 127 accommodating a pair of third auxiliary link members 175 (to be described later). The second hinge axle 123 is rotatably combined to the second hinge axle holding part 103 formed on the other second lower opposite part 100a of the upper link member 100 by passing through a second hinge axle accommodating part 56 formed on the other first upper opposite part 50b of the lower link member 50.
Thus, the upper link member 100 is rotatable relative to the lower link member 50 about the axis of the first and second hinge axles 113 and 123.
The monitor hinge 130 includes the first and second monitor hinge parts 131 and 141 rotatably connecting the second upper opposite parts 100b of the upper link member 100 to the first and second monitor brackets 80 and 90.
The first monitor hinge part 131 includes a third hinge pin 133 formed with a first end 133a having a circular cross section and a second end 133b having a noncircular cross section, a third pin accommodating part 83 formed on one side of the third monitor bracket 80 to receive the first end 133a of the third hinge pin 133 rotatable therein, and a third pin holding part 105 protruding from one of the second upper opposite parts 100b of the upper link member 100 and fitting the second end 133b of the third hinge pin 133 therein.
The third hinge pin 133 has the same shape as the first and second hinge pins 63 and 73, and the first end 133a of the third hinge pin 133 is rotatably inserted in the third pin accommodating part 83 formed on the one side of the first monitor bracket 80. Further, the second end 133b of the third hinge pin 133 is fitted in the third pin holding part 105 formed on the second one upper opposite part 100b of the upper link member 100, so that the second end 133b of the third hinge pin 133 does not rotate relative to the monitor main body 10. Here, the first monitor bracket 80 fastened to the monitor main body 10 is rotated relative to the upper link member 100 about an axis of the third hinge pin 133.
The second monitor hinge part 141 includes a fourth hinge pin 143 formed with a first end 143a having a circular cross section and a second end 143b having a noncircular cross section, a fourth pin accommodating part 93 formed on one side of the second monitor bracket 90 to receive the first end 143a of the fourth hinge pin 143 rotatable therein, a third hinge axle 145 fitting the second end 143b of the fourth hinge pin 143 therein and rotating coincidentally with the fourth hinge pin 143, a third hinge axle accommodating part 106 protruding from the other one of the second upper opposite parts 100b of the upper link member 100 to receive the third hinge axle 145 rotatable therethrough, a second friction spring 144 interposed between the fourth pin accommodating part 93 and the first end 143a of the fourth hinge pin 143 and resisting a rotation of the fourth hinge pin 143, and a tilt restricting part 151 restricting a tilt of the monitor main body 10 relative to the upper link member 100 within a second predetermined angle range.
The first end 143a of the fourth hinge pin 143 is inserted in the second friction spring 144, so that the friction is produced when the fourth hinge pin 143 is rotated relative to the second friction spring 144, and it is possible that the friction is stronger than a torque due to the weight of the monitor main body 10 rotating about an axis of the fourth hinge pin 143. Further, the second friction spring 144 is matched with the fourth pin accommodating part 93 to rotate coincidentally with the fourth pin accommodating part 93 of the second monitor bracket 90.
The second end 143b of the fourth hinge pin 143 is fitted in a fourth pin holding part 146 formed on a first end of the third hinge axle 145, so that the fourth hinge pin 143 rotates coincidentally with the third hinge axle 145.
The first end of the third hinge axle 145 is formed with the fourth pin holding part 146 holding the second end 143b of the fourth hinge pin 143 therein so as to rotate coincidentally with the fourth hinge pin 143, and a second end of the third hinge axle 145 is formed with a fourth auxiliary link combination part 147 accommodating the third auxiliary link members 175. Further, the third hinge axle 145 is rotatably inserted into the third hinge axle accommodating part 106 provided in the other second upper opposite part 100b of the upper link member 100. Here, the second monitor bracket 90 fastened to the monitor main body 10 is rotatable relative to the other second upper opposite part 100b of the upper link member 100 about the axis of the fourth hinge pin 143. Here, the third hinge axle 145 rotating coincidentally with the fourth hinge pin 143 is rotatably inserted into the third hinge axle accommodating part 106 provided in the other second upper opposite part 100b of the upper link member 100, with its rotation being limited because the third hinge axle 145 is interlocked with the third auxiliary link member 175 connected to the third hinge axle 145, and this limited rotation of the third hinge axle 145 will be described later in more detail.
Thus, the monitor main body 10 is rotatable relative to the upper link member 100 about the axes of the third and fourth hinge pins 133 and 143.
The tilt restricting part 151 includes a tilt restricting washer 152 irrotatably or fixedly coupled to the fourth hinge pin 143, and a flat spring 155 combined to the second monitor bracket 90 by screws and rotating coincidentally with the monitor main body 10.

The flat spring 155 is formed with an elastic projection part 157 disposed between the second stoppers 153 of the tilt restricting washer 152 and allows the monitor main body 10 to be tilted relative to the upper link member 100 within the second predetermined angle range. For instance, a tiltable angle of the monitor main body 10 ranges from −5° to 30°. Here, the tiltable angle is determined according to a design of the second stoppers 153, so that the tiltable angle can be changed by modifying the second stoppers 153 (refer to

Thus, the first pin through hole 161 formed on the lower part of the first auxiliary link member 160 is movably coupled by using the first link pin 37 to the first auxiliary link supporting part 35 of the first base bracket 30 fastened to the base member 20. The first pin through hole 161 formed on the upper part of the first auxiliary link member 160 is movably coupled by using the first link pin 37 to the first auxiliary link combination part 115 formed on the second end of the first hinge axle 113 rotating coincidentally with the upper link member 100. Therefore, the first auxiliary link member 160 operates parallel to the lower link member 50 according to a the rotation of the lower link member 50 relative to the base member 20.
As shown in
On the other hand, the first pin through hole 161 of the lower part of the first auxiliary link member 160 is coupled to the first auxiliary link supporting part 35 at the position deviated from the rotation axis of the first hinge pin 63. The first pin through hole 161 of the upper part of the first auxiliary link member 160 is coupled to the first auxiliary link combination part 115 at the position deviated from the rotation axis of the first hinge axle 113. Here, a rotation ratio of the upper link member 100 to the lower link member 50 can be adjusted according to different deviations of the lower and upper parts of the first auxiliary link member 160 from the first hinge pin 63 and the first hinge axle 113, respectively. In this embodiment, a deviation degree of the lower part of the first auxiliary link member 160 about the first hinge pin 63 is larger than that of the upper part of the first auxiliary link member 160 about the first hinge axle 113, so that the upper link member 100 is rotated greater in proportion to the rotation of the lower link member 50. For instance, when the lower link member 50 is rotated at an angle of 90° with respect to the base member 20, the upper link member 100 is rotated at an angle of 145° with respect to the base member 20.
With this configuration, a height of the monitor main body 10 with respect to the base member 20 can be adjusted as follows. As shown in
The second auxiliary link member 170 forms a pair of linking members which are respectively disposed at a position deviated from rotation axes of the second hinge axle 123 of the second link hinge part 121 and the second hinge pin 73 of the second base hinge part 71 to move parallel to the lower link member 50. Further, the second auxiliary link member 170 connects the second link hinge part 121 with the base member 20, and transmits the rotary motion from the lower link member 50 relative to the base member 20 to the third auxiliary link member 175.
The second auxiliary link member 170 is shaped like a pair of bars having the same length. The second base bracket 40 is formed with a second auxiliary link supporting part 45 coupled with a lower part of the second auxiliary link member 170. The first end of the second hinge axle 123 of the second link hinge part 121 is formed with the second auxiliary link combination part 125 coupled with an upper part of the second auxiliary link member 170.
The second auxiliary link supporting part 45 and the second auxiliary link combination part 125 are formed with a pair of second pin holes 46 spaced-apart from each other at a position deviated from the rotation axes, respectively. Opposite end parts of the second auxiliary link member 170 are formed with second pin through holes 171, respectively, to be aligned with the second pin holes 46. Further, second link pins 47 are inserted in the second pin holes 46 through corresponding ones of the second pin through holes 171, respectively.
Thus, the second pin through hole 171 formed on the lower part of the second auxiliary link member 170 is movably coupled by using the second link pin 47 to the second auxiliary link supporting part 45 of the second base bracket 40 fastened to the base member 20. The second pin through hole 171 formed on the upper part of the second auxiliary link member 170 is movably coupled by using the second link pin 47 to a lower part of the second auxiliary link combination part 125 formed on the first end of the second hinge axle 123 movably coupled with a lower part of the third auxiliary link member 175. Therefore, the second auxiliary link member 170 operates parallel to the lower link member 50 according to the rotation of the lower link member 50 relative to the base member 20.
As shown in
The third auxiliary link member 175 is formed with a pair of linking members which are respectively disposed at a position deviated from rotation axes of the second hinge axle 123 of the second link hinge part 121 and the fourth hinge pin 143 of the second monitor hinge part 141, to move parallel to the upper link member 100. Further, the third auxiliary link member 175 connects the second link hinge part 121 with the second monitor hinge part 141 and transmits the rotary motion from the upper link member 100 relative to the lower link member 50 to the monitor main body 10.
The third auxiliary link member 175 is shaped like a pair of bars having the same length, and disposed between the first and second link hinge parts 111 and 121 of the upper link member 100 and between the first and second monitor hinge parts 131 and 141 of the upper link member 100. The second end of the second hinge axle 123 is formed with a third auxiliary link supporting part 127 coupled with a lower part of the third auxiliary link member 175. The second end of the third hinge axle 145 is formed with the third auxiliary link combination part 147 coupled with an upper part of the third auxiliary link member 175.
The third auxiliary link supporting part 127 and the third auxiliary link combination part 147 are formed with a pair of third pin holes 128 spaced-apart from each other at a position deviated from the rotation axes, respectively. Opposite end parts of the third auxiliary link member 175 are formed with third pin through hole 171 to be aligned with the third pin holes 128. Further, third link pins 129 are inserted in the third pin holes 128 through corresponding ones of the third pin through hole 176, respectively.
Thus, the third pin through hole 176 formed in the lower part of the third auxiliary link member 175 is movably coupled by using the third link pin 129 to the third auxiliary link supporting part 127 of the second end of the second hinge axle 123. The upper part of the third auxiliary link member 175 is movably coupled by using the third link pin 129 to the third auxiliary link combination part 147 of the third hinge axle 145. Therefore, the third auxiliary link member 175 operates parallel to the upper link member 100 according to a rotation of the upper link member 100 relative to the lower link member 50.
As shown in
To the contrary, as shown in
With this configuration, the monitor main body 10 of the monitor according to the present invention can be rotated as follows. The monitor main body 10 is rotated by the rotation of the lower link member 50 since the second auxiliary link member 170 rotates parallel to the lower link member 50, and the third auxiliary link member 175 having the lower part interlocked with the second auxiliary link member 170 and the upper part coupled to the third hinge axle 145 rotates parallel to the upper link member 100. Further, when the upper link member 100 is rotated downwardly to the lower link member 50, the monitor main body 10 rotates backward. When the upper link member 100 is rotated upwardly from the lower link member 50, the monitor main body 10 rotates forward. Here, when the height of the monitor main body 10 is adjusted, a tilting angle of the monitor main body 1.0 with respect to a line perpendicular to the base member 20 is not changed.
As shown in
The base bracket 180 includes a plurality of hooks 182 to be latched to a plurality of hook holes 22 formed on the base member 20, a plurality of first combining holes 183 allowing the base bracket 180 to be installed to the inclined plane, and a plurality of second combining holes 185 to combine the base member 20 with the base bracket 180. Further, the base member 20 is formed with a plurality of third combining holes 25 corresponding to the second combining holes 25, and is combined with the base bracket 180 by second screws 186.
Here, the second combining holes 185 of the base bracket 180 and the third combining holes 25 of the base member 20 are formed in consideration of a VESA regulation, so that the monitor can be installed to an arm stand 190 (see
In the foregoing embodiment, the torsion spring is provided in the first base hinge part. However, another torsion spring may be provided in at least one of the first and second monitor hinge parts and the second base hinge part.
In the foregoing embodiment, the rotation restricting part is provided in the second base hinge part. However, another rotation restricting part may be provided in the first base hinge part.
In the foregoing embodiment, the tilt restricting part is provided in the second base hinge part. However, another tilt restricting part may be provided in the first base hinge part.
In the foregoing embodiment, the first and second friction springs are provided in the first second base hinge part and the second monitor hinge part, respectively. However, other friction springs may be provided in the second base hinge part and the first monitor hinge part.
As described above, the present invention provides a monitor in which an allowable height adjustment of a monitor main body is relatively large, and costs for keeping and carrying the monitor can be decreased by decreasing a packing volume of the monitor.
Further, the present invention provides a monitor, in which a height of a monitor main body can be adjusted without changing a tilting angle of the monitor main body, and the tilting angle of the monitor main body with respect to a base member can be properly adjusted.
Further, the present invention provides a monitor, in which a base member is detachably combined with a base bracket and can be installed onto an inclined plane such as a wall, an arm stand, etc., and particularly, easily installed onto various arm stands according to the VESA regulation.
Although an embodiment of the present invention has been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
