Description

[DESCRIPTION] [TITLE OF INVENTION]
STAND AND DISPLAY DEVICE USING THE SAME [TECHNICAL FIELD] The present invention relates to a stand and a display device using the same. More specifically, the present invention relates to a stand and a display device, which is selectively mountable to a fixing object such as a partition. [BACKGROUND ART] Display devices are appliances that are used in TVs, computers or variations of them to display images. Braun tube, Liquid Crystal Display (LCD) , Plasma Display Panel (PDP) are known. A popular technology presently in use is the Flat Panel Display (FPD) , which is thin, including LCD and PDP. In the use of the Flat Panel Display, a display unit for displaying images is thin and a stand for supporting the display unit takes relatively big space, compared with the display unit. It is common that the FPD is mounted on a desk or table and a wall-mountable FPD may be used which may be hung on a wall, a partition or the like.
In reference to FIG. 1, a conventional LCD monitor having a wall-mounting function will be now explained.
A wall-mountable LCD monitor includes a display unit 12, a base 14 and a supporting unit 16. The supporting unit 16 is provided between the display unit 12 and the base 14 to support the display unit 12. Commonly, the supporting unit 16 and the base 14 are rotatable by a hinge 18.
As shown in FIG. 2, in a rear surface of the base 14 are provided a plurality of fastening holes 20 to install a LCD monitor to a perpendicular wall. Once screws (not shown) are fastened to the fastening holes 20 provided on the base 14, the screws for being fastened to a wall are inserted in a groove of a wall-mount bracket (not shown) additionally provided on a wall and thus the LCD monitor is affixed to the perpendicular wall.
[DISCLOSURE OF INVENTION] [TECHNICAL PROBLEM]
However, the conventional display device, especially those having a wall-mount function, have some problems.
First, the conventional display device should be mounted on a wall by using an auxiliary wall mount bracket or a variation of it. Also, if a user try to move the position of the wall mounted display device, it is not easy for a user to disassemble the display device because of the complex structure. Since it is expensive and its structure is complex, it is inconvenient for a user to use the conventional display device.

[BEST MODE]
Reference will now be made in detail to the specific embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In reference to FIG. 3, a stand and a display unit having the same will be explained.
As shown in FIG. 3, a display device 1 includes a display unit 110 and a stand 100 that supports the display unit 110. The stand 100 includes a base unit 170 and a supporting unit 130. The stand 100 according to the present invention further includes a clamp unit 150 that detachably secures the display device 1 to a partition and a variation of it. Each component will now be explained in detail.
The display unit 110 may be a CRT, LCD, PDP and other various kinds and it is preferred that the display unit 110 is LCD or PDP that is a kind of FPD.
The base unit 170 is a part contacted with a horizontal surface when the display device 1 stands on the horizontal surface to use. The supporting unit 130 is provided between the base unit 170 and the display unit 110. The supporting unit 130 may be rotatable about the base unit 170 by using a hinge 172. It is preferred that the display unit 110 is movable upward and downward to adjust the height of display unit 110. Specifically, the supporting unit 130 may include a connection member 131 connected to the base unit 170 and a height adjusting member 134 movable upward and downward along the connection member 131. The display unit 110 may be directly connected to the supporting unit 130 to be used. However, it is preferred that the display unit 110 is connected to the supporting unit 130 and tilting or pivoting is possible, which is convenient to a user.
More specifically, the height adjusting member 134 is connected to the connection member 131 and it is movable upward and downward with respect to the connection member 131. A tilting member 210 is fastened to the height adjusting member 134 by a hinge 132 and a pivoting member 220 is fastened to the tilting member 210. As a result, the display unit 110 is fastened to the pivoting member 220. If the height adjusting member 134 is not used, the tilting member 210 may be directly connected to the connection member 131. The above hinge fastening structure, tilting structure and pivoting structure are well-known and thus the detailed description will be omitted.
FIGS. 4a to 4c show that the display unit 110, exactly, the connection member 131 of the supporting unit 140 is rotating about the base unit 170. FIGS. 5a and 5b show that the display unit 110, exactly, the tilting member 210 is tilting with respect to the connection member 131 of the supporting unit 130. It is preferred that the tilting angle is 180° (see FIG. 5b) . In reference to FIGS. 6 and 7, the clamp unit 150 will be now explained.
As mentioned above, the clamp unit 150 detachably secures the display unit 110 to a fixing object such as a partition 2. The fixing object is not limited to the partition 2 and it may be any plate shaped object having a predetermined thickness. The installation angle of the fixing object may be variable and the clamp unit 150 may be usable in the fixing object installed vertically or horizontally. The clamp unit 150 includes a first securing member 154, a second securing member 156. A front end of the first securing member 154, that is rotatable, is connected to the base unit 170. The second securing member 156 is connected to a rear end of the first securing member 154 at a predetermined angle. It is preferred that the second securing member 156 is substantially parallel to a rotational shaft 154b of the first securing member 154. That is, the second securing member 156 is substantially parallel to a plane surface defined by a lower surface of the base unit 170 and the first securing member 154 perpendicularly connects the base unit 170 to the second securing member 156.
According to the above structure, the partition 2 is closely contacted between the lower surface of the base unit 170 and the second securing member 156. As a result, the display device 1 can be secured to the partition 2. On the other hand, a roller 160 may be provided at the second securing member 156 to allow the clamp unit 150 to move at the fixing object. Also, a bushing 158 may be provided between the second securing member 156 and the roller 160. Even when the display unit 10 is supported to the fixing object by the roller 160, the display unit 110 may be movable smoothly in a right-and-left direction.
It is preferred that the clamp unit 150 is provided in pairs. The pair of the clamp units 150 may be symmetric. That is, the fixing object such as the partition 2 is positioned between the plane surface defined by the lower surface of the base unit 170 and a plane surface defined by the pair of the second securing member 156.
If a pair of clamp units 150 are provided, it is preferred that either of the pair is detached and the other is detached together. That is, if either of the pair is rotated, the other is automatically rotated, which is convenient. For that, the pair of the first securing members 154 may have ends 154 that are substantially contacted with each other. For example, ends 154a of the firs securing members 154 may be directly contacted with each other or may be indirectly contacted with each other.
As shown in FIG. 8a, it is preferred that a plurality of gear teeth 162 may be provided at a contact part 154a of the first securing member 154 for safe power transmission. As a result, if either of the first securing members 154 is rotated, the other of the first securing member 154 is rotated at the same angle by the gear teeth 162.
Here, the gear teeth 162 is a kind of a power transmission part and the power transmission part may be variable rather than the gear teeth 162. For example, a timing belt may be used to connect the ends of the first securing members 154.
If the clamp unit 150 is secured to a predetermined fixing object, it is preferred that the rotation of the clamp unit 150, specifically, the first securing member 154 is prevented. Thus, a rotation prevention member may be further provided to prevent the rotation of the clamp unit 150.
In reference to FIG. 8, the rotation prevention member will now be explained.
The rotation prevention member includes a prevention member 152 and a locking member 151. The prevention member 152 has gear teeth 152b that is able to be selectively engaged with the gear teeth 162 of the first securing member 154. The locking member 151 controls the operation of the prevention member 152. Once the gear teeth 152b of the prevention member 152 are engaged with the gear teeth 162 of the first securing member 154, the first securing member 154 is not able to rotate. More specifically, an end of the locking member 151 is fastened to the base unit 170 by a hinge 151a. An end of the prevention member 152 is fastened to the base unit 170 by a hinge 152a and the other end of the prevention member is rotatably connected to a predetermined portion of the locking member 151 by a hinge 151b.
In reference to FIGS. 8a to 8d, the operation of the clamp unit 150 will be explained.
The clamp unit 150 is usually held in the base unit 170 (see FIG. 8a) . When trying to use the clamp unit 150, a user lifts the locking member 151 to release locking (see FIG. 8b) . If the locking is released, the user rotates either of the pair of the first securing members 154 such an angle as he/she wants. That is, the clamp unit 150 held in the base unit 170 is taken out (see FIG. 8c). When the clamp unit 150 is spaced apart at a predetermined angle from the base unit 170, the prevention member 152 is re-locked (see FIG. 8d) . Hence, the fixing object is inserted between the clamp unit 150 and the lower surface of the base unit 170, which completes the mounting process of the display device to the fixing object such as the partition 2.
The above embodiment describes that the clamp unit 150 is held in the lower surface of the base unit 170 and the present invention is not limited thereto. For example, the clamp unit 150 may be fastened to a side surface of the base unit 170 or to the supporting unit 130.
On the other hand, a height adjusting member 134 may be provided to adjust the height of the display unit 110 by moving the display unit upward and downward (see FIG. 3) . If the height adjusting member 134 is used, a supporting member 140 may be further provided to support the display unit at a predetermined force in spite of the display unit 110 moving upward and downward. A static load spring may be used in the supporting member 140. Elasticity of springs is typically changeable in proportion to displacement of springs. However, elasticity of static load springs is consistent regardless of displacement of static load springs. A spiral spring is used as a static load spring. In reference to FIGS. 9to 11a, the supporting member 140 will be explained.
A direction of load is changed by the display unit 110 when the display unit 110 is standing erect or inverse (see FIG. 9b) . The display unit 110 should be supported by the supporting member 140, standing erect or inverse.
Thus, the supporting member 140 includes a first supporting member 136 and a second supporting member 138. The first supporting member 136 supports the display unit 110 when the display device is standing erect. The second supporting member 138 supports the display unit 110 when the display device is standing inversely. That is, the first supporting member 136 and the second supporting member 138 selectively support the load of the display unit 110. The adjustment between the first supporting member 13 and the second supporting member 138 is performed by an adjusting member 142 provided at the height adjusting member 134.
In reference to FIGS. 10 and 11a, the supporting member and the adjusting member will be now explained in detail.
The load of the display unit 110 is substantially applied to the height adjusting member 134 and thus the supporting member 140 is provided between the connection member 131 and the height adjusting member 134. An end of the first supporting member 136 is secured to an upper portion of the connection member 131 and the other opposite end of the first supporting member 136 is selectively connected to the adjusting member 142. An end of the second supporting member 138 is secured to a lower portion of the connection member 131 and the other opposite end of the second supporting member 138 is selectively connected to the adjusting member 142.
The adjusting member 142 includes a housing 141 and an engaging member 144. The housing 141 is fastening to the height adjusting member 134. The engaging member 144 is provided inside the housing 141. The engaging member 144 includes a first engaging part 144a corresponding to the first supporting member 136, a second engaging part 144b corresponding to the second supporting member 138, a first button 146a and a second button 146b. Also, the engaging member 144 is rotatable about a pin 141a and it is elastically supported by an elastic member 143.
Also, a stopper 145 is provided at an outer surface of the housing 141 and the stopper 145 is movable along a guide hole 135 of the connection member 131 when the height adjusting member 134 moves upward and downward (see FIG. 9a) . That is, the guide hole 135 and the stopper 145 are employed as a guide and a stopper, respectively, when the display unit 110 moves upward and downward to prevent the display unit 110 from moving farther when it reaches an upper and lower end of the guide hole 135. As shown in FIG. lib, the button 146 may be formed at the engaging member 144 and the elastic member 143 may be provided between the engaging member 144 and the housing 141. In this case, if the button 146 is pushed, the engaging member 144 moves leftward, seen from the drawings, against the elasticity of the elastic member 143. Hence, the first supporting member 136 and the second supporting member 138 are released from the engaging member 144 at the same time. In this case, the button 146 may be employed as a stopper. In reference to FIG. 11a, the operation of the supporting member 140 and the adjusting member 142 will be explained.
When the display device is standing erect, the front end 13βa of the first supporting member 136 is engaged with the first engaging part 144a, such that the first supporting member 136 supports the load of the display unit 110.
Alternatively, when the display device is mounted to the fixing object such as the partition 2, the display unit 110 should be substantially standing inverse. In the state of the display device standing inverse, the load of the display unit 110 is downward and the elasticity of the first supporting member 136 is also downward. As a result, it is difficult for the first supporting member 136 to support the display unit 110. Accordingly, when the display device is standing inverse, the second supporting member 138 should support the load of the display unit 110.
In reference to FIGS, lla and 12, the adjusting process for the display device standing inverse will be explained. Here, FIGS. 12a, 12c, 12d and 12e are front views and FIG. 12b is a rear view.
When the display device is standing erect, the first supporting member 136 is engaged with the first engaging part 144a. If the display device is changed to stand inverse, the following process is performed. Once the height adjusting member 134 is lifted upward, the second button 146 is pushed (see FIGS. 12a and 12b) . When the second button 146b is pushed, the second engaging part 144b is pushed and the first engaging part 144a is lifted to release the first engaging part 144a connected to the first supporting member 136. The engaging member 144 is supported in the adjusting member 142 by the elastic member 143 and the engaging member 144 may return to its original position if the pushing is removed. When the first supporting member 136 is released from the first engaging part 144a, the height adjusting member 134 moves downward slowly to connect the second supporting member 138 with the second engaging part 144b (see FIGS. 12c and 12d) . At this time, it is preferred that the first button 146a is pushed.
If the height adjusting member 134 moves downward, the stopper 145 moves along the guide hole 135 formed at the connection member 131. When the stopper 145 reaches a lower end of the guide hole 135, the stopper 145 stops the height adjusting member 134 from moving farther.
When the second supporting member 138 is engaged with the second engaging part 144b, the display device is turned over to be mounted to the fixing object by using the clamp unit 150. As shown in FIGS. 13 and 14, the display device is turned over and it is mounted to the fixing object as a user wants by the clamp unit 150, the second supporting member 138 being engaged with the second engaging part 144b. As mentioned above, when the display device is standing inverse, the second supporting member 138 supports the display unit 110.
The adjusting process for the display device standing inverse as shown in FIG. lib is the same and thus detailed description will be omitted.
The structure of the supporting part 144 mentioned above is applicable to a stand without the clamp unit.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
[INDUSTRIAL APPLICABILITY] The stand and the display device according to the present invention have an industrial applicability.
First, the display device according to the present invention may be mountable to a fixing object such as a partition by using the clamp unit without an auxiliary bracket or variation of it. Also, when trying to move the display device, the display device is conveniently detachable without screw fastening, which enables a user to change the position of the display device in a right and left direction as he/she wants. As a result, user convenience may be enhanced.
Furthermore, the stand of the display device can support the display device by the restitution of the supporting member, which is a spring, when the display device is rotated 180° as well as standing erect. A still further, the display device can be mounted to a partition or variation of it by using the clamp unit without an auxiliary mounting stand that is relatively expensive.
