CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Korean Patent Application No. 2005-0080876, filed on Aug. 31, 2005, in the Korean Intellectual Property Office, which is hereby incorporated in its entirety by reference for all purposes as if fully set forth herein.
SUMMARY OF THE INVENTION Accordingly, the present general inventive concept provides a display apparatus that is capable of lifting the display main body more safely and locking the display main body in a predetermined position.
BRIEF DESCRIPTION OF THE DRAWINGS These and/or other aspects of the present general inventive concept will become apparent and more readily appreciated from the following description of the exemplary embodiments, taken in conjunction with the accompany drawings, in which:
Referring to FIGS. 2 through 5, the rail supporter 52 has a cross section of a �U� shape to support the guide rail 75 at opposite sides thereof. The rail supporter 52 may comprise a metal material to maintain a predetermined strength. Alternatively, the rail supporter 52 may be made of different materials, such as plastics and the like.
As illustrated in FIGS. 4 and 5, the lifting spring member 71 is provided as a spiral spring type and is coupled with the guide frame 51 and the lifting member 61. The first side 71 a of the lifting spring member 71 is coupled to the lifting member 61, and a second side 71 b of the lifting spring member 71 is supported by the lifting spring supporting part 72 provided in the guide frame 51. In other words, the second side 71 bof the lifting spring member 71 is wound in a roll shape and is supported by the lifting spring supporting part 72. The first side 71 aof the lifting spring member 71 extends from the second side 71 band is coupled to the lifting spring coupling part 63 of the lifting member 61. The lifting spring member 71 may provide an elastic force that counteracts the weight of the display main body 10, thereby preventing the display main body 10 from moving downward due to the force of gravity. Accordingly, a user can easily move the display main body 10 upward and downward with a relatively small pressure to overcome a friction force of the guide rail 75. The front side 71 a of the lifting spring member 71 may be moved with respect to the second side 71 baccording to movement of the lifting member 61 by unwinding and winding of the lifting spring member 71. The lifting spring member 71 is not limited to the spiral spring type, and may comprise different elastic bodies such as a coil spring, a plate spring, rubber, etc.
As illustrated in FIG. 5, the lifting spring supporter 72 is formed with a spring seating part 73 having a circular arc shape corresponding to the shape of the second side 71 bof the lifting spring member 71 to support the lifting spring member 71 thereon. The lifting spring supporter 72 is coupled to a frame coupling part 74 provided in the guide frame 51 by a fastener, such as a screw 79.
