The present invention relates to a display device and a support stand therefor, and more particularly, to a plasma display device support stand having a stand member at a lower portion thereof such that it can stably stand upright.
Generally, a plasma display device displays images on a plasma display panel (hereinafter referred to as a PDP) using plasma generated by the discharge of gas.
Such a plasma display device may include a PDP, a chassis base that is disposed parallel to the PDP, a heat transferring medium that is disposed between the PDP and the chassis base and which contacts the PDP, and driving circuits that are mounted on a surface of the chassis base which drive the PDP. A front case is coupled at the side of the PDP, and a back case is coupled to the side of the driving circuits.
In order to support such a plasma display device, a stand guide is coupled to a lower portion of the chassis base. A stand bar is inserted into a receiving hole of the stand guide and is coupled to the stand guide with a bolt. A lower portion of the stand bar is integrally coupled to a stand base, and the stand base contacts a bottom surface so that the plasma display device can stand upright.
Generally, the size of the plasma display device is greater than 40 inches and is very heavy. Therefore, while inserting the stand bar into the receiving hole of the stand guide and moving the assembled plasma display device, there can be a collision between the stand bar and the stand guide, the impact of which can be transferred to the plasma display panel via the chassis base so that the PDP can be damaged or a dark point can be formed thereon.
In accordance with the present invention a support stand for display devices is provided in which a shock caused as a result of a collision between a stand bar and a stand guide can be decreased.
A display device is provided which includes a chassis base, a display panel, a connecting member, a stand member, and a shock absorbing member. The display panel is attached to the chassis base, and the connecting member is coupled to the chassis base. The stand member is connected to the connecting member such that the stand member supports the chassis base to which the display panel is attached. The shock absorbing member is disposed between the connecting member and the stand member such that the shock absorbing member absorbs a shock by a collision between the connecting member and the stand member.
In one exemplary embodiment, the connecting member is a stand guide having a receiving hole that is opened in a downward direction, and the stand member includes a stand base and a stand bar, an upper portion of which is inserted into the receiving hole of the stand guide and a lower portion of which is coupled to the stand base.
In a further exemplary embodiment, the shock absorbing member is disposed between an upper surface of the receiving hole and an upper surface of the stand bar. Further, the shock absorbing member may be coupled to the upper surface of the stand bar through a coupling member.
In another exemplary embodiment, a hanging step is formed on the stand bar, and the shock absorbing member is disposed between the hanging step and a bottom surface of the stand guide. Further, the shock absorbing member may have a ring shape.
In a further embodiment, an upper surface of the receiving hole and an upper surface of the stand bar are distanced from each other.
Moreover, the connecting member may be coupled to a surface of the chassis base that is opposite to a surface of the chassis base to which the display panel is attached.
Additionally, the shock absorbing member may be made of a rubber material.
As shown in
A heat transferring layer (not shown) may be disposed between the chassis base 103 and the plasma display panel 101. Driving circuits (not shown) for driving the plasma display panel 101 may be mounted on a rear surface of the chassis base 103.
The plasma display device 100 according to one embodiment of the present invention includes a connecting member 105, which is coupled to a lower portion of the rear surface of the chassis base 103 that is opposite to a surface to which the plasma display panel is attached, and a stand member 107 that is connected to the connecting member 105 and supports the chassis base 103 to which the plasma display panel 101 is attached.
The stand member 107 may be a combination of a stand base 109 and a stand bar 111 that is upwardly extended from the stand base 109, and the connecting member 105 may be a stand guide 113 that can be connected with the stand bar 111.
As shown in
As further shown in
The shock absorbing member 119 can be made of any material that can be deformed in response to a shock and that can absorb the shock. As an example, the shock absorbing member 119 can be made of a rubber material or a high-density polyurethane such as a BUMPON®.
As also shown in
Therefore, when the stand bar 111 is inserted into the receiving hole 115 of the stand guide, the shock absorbing member 119 can decrease (be compressed) to absorb a shock as a result of a collision between the stand bar 111 and the stand guide 113.
In an exemplary embodiment, the shock absorbing member 119 is coupled to the upper surface 121 of the stand bar 111 through a coupling member 125 such as a bolt. Instead of a bolt, any coupling member such as a bonding agent can be used for coupling the shock absorbing member 119 to the stand bar 111.
In another exemplary embodiment, an upper surface of the coupling member 125 is lower than an upper surface of the shock absorbing member 119 such that the upper surface of the coupling member 125 does not directly collide with the stand guide 113.
Referring to
As shown in
The connecting member 205 can be a stand guide 213 including a receiving hole 211 that is opened in a downward direction, and the stand member 207 can be a combination of a stand bar 215, an upper portion of which is inserted into the receiving hole 211, and a stand base 217 to which a lower portion of the stand bar 215 is coupled.
As shown in
A through hole 209a is formed at a center portion of the shock absorbing member 209, so that the shock absorbing member 209 has a ring shape. The upper portion 215b of the stand bar 215 is inserted into the through hole 209a of the shock absorbing member 209 and is hung on the hanging step 219. In this state, the upper portion 125b of the stand bar 215 is inserted into the receiving hole 211 of the stand guide 213. That is, the shock absorbing member 209 is disposed between the hanging step 219 and a bottom surface 221 of the stand guide 213.
Therefore, when the stand bar 215 is inserted into the stand guide 213, a shock by a collision between the stand bar 215 and the stand guide 213 can be absorbed by the shock absorbing member 209.
At this time, an upper surface 223 of the stand bar 215 and an upper surface 225 of the receiving hole 211 are distanced from each other by a predetermined distance, so that the stand bar 215 can be prevented from directly colliding with the stand guide 213.
Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
The plasma display device according to the embodiments of the present invention includes the shock absorbing member that is disposed between the stand guide and the stand bar, so that a shock that can be generated while inserting the stand bar into the stand guide or while moving the plasma display device can be decreased.
While embodiments have been described with regard to plasma display panels, those skilled in the art can appreciate that the support stand can also be used with other flat panel display devices such as liquid crystal displays, organic electroluminescent displays, field emission displays and the like.
