This application claims the benefit under 35 U.S.C. � 119(a) of Korean Patent Application No. 2005-0021276, entitled “Display Apparatus,” filed on Mar. 15, 2005, the entire disclosure of which is hereby incorporated by reference.
The present invention relates to a display apparatus. More particularly, the present invention relates to a display apparatus having an improved base part supporting a display main body and a coupling structure of a stand part and the base part.
Generally, a display apparatus refers to monitors for devices, such as televisions or computers, that display a picture employing a cathode ray tube (CRT), a liquid crystal display (LCD), a plasma display panel (PDP) or a similar display apparatus.
For example, an LCD monitor includes a display main body displaying the picture through an LCD panel, a base part supporting the display main body, and a stand part provided between the display main body and the base part.
When the LCD monitor is packed for transferring or shipping, a packing volume thereof increases in the assembled state when the stand part is coupled to the display main body and to the base part. To solve the above problem, an LCD monitor has a base part detachable from the stand part (for example, see Korean Utility Model No. 316585), thereby reducing the packing volume during transfer. For reference, the display main body, the base part and the stand part respectively are identified as a monitor, a stand base and a stand post in the LCD monitor of Korean Utility Model No. 316585.
The conventional LCD monitor includes the stand base, the stand post coupled to the stand base, and a monitor supported by the stand post. The stand post and the stand base are detachable from each other and are coupled by a spring. A lower end of the spring is coupled to a pin provided in the stand base, and an upper end of the spring is coupled to a pin provided in the stand post.
In the conventional display apparatus, the stand part is provided to separate from the base part to reduce the packing volume, such that the base part may be lost. Even after the stand part couples with the base part, the stand part may become separated from the base part by external impacts.
Accordingly, a display apparatus according to exemplary embodiments of the present invention has a stand part and a base part foldable onto the display main body to reduce the packing volume without separating the base part from the stand part.
Accordingly, a need exists for an improved display apparatus having a base part and a stand part foldable onto the display main body without separating the base part and that prevents accidental separation of the base part from the stand part when subjected to external impacts.
Accordingly, exemplary embodiments of the present invention provide a display apparatus having a base part rotatable about a stand part and that supports the stand part and the display main body on an installation surface in a supporting position. The base part may be tilted, or rotated, to a folding position for transfer of the display apparatus, and the base part as well as the stand part are folded substantially parallel to a rear surface of the display main body to reduce a packing volume.
The foregoing and other objects are substantially realized by providing a display apparatus having a display main body adapted to display a picture, a base part adapted to be mounted on an installation surface and supporting the display main body, and a stand part provided between the base part and the display main body. A first hinge part is disposed between the display main body and the stand part and adapted to fold the stand part onto a rear surface of the display main body. A second hinge part is disposed between the stand part and the base part, and adapted to tilt the base part between a supporting position where the base part is mounted in a transverse direction with respect to an arranging direction of the stand part and a folding position where the base part is mounted substantially parallel to a first side of the stand part along the arranging direction of the stand part. A locking assembly prevents and allows the base part from being and to be tilted between the supporting position and the folding position.
The locking assembly may include a projection provided in one of the stand part and the base part. A coupling unit is disposed in the other one of the stand part and the base part and is adapted to couple to the projection to prevent the base part from being tilted, and to uncouple the projection to allow the base part to be tilted.
The coupling unit may include a casing part having a first side thereof adapted to couple to the stand part and a second side thereof adapted to couple to the base part. A coupling part is coupled to slide in the casing part, and is adapted to be coupled to the projection and to be uncoupled from the projection.
The coupling unit may further include a spring member having a first end thereof supporting the casing part and a second end thereof supporting the coupling part to supply an elastic force to the coupling part.
The coupling unit may further include an operating knob provided in the coupling part for sliding the coupling part.
The second hinge part may include a hinge protrusion provided in one of the stand part and the base part, and a protrusion holder provided on the other one and tiltably accommodating the hinge protrusion.
