Title: Detachable base of a display

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a detachable base of a display and, more particularly, to a detachable base of a flat panel display.  
      2. Description of the Related Art  
      Generally, the design for a base of a flat panel display requires stability for balance; therefore the size of the base is relatively large, which occupies a significant amount of packing space and causes difficulties with transportation.  
      Therefore, it is desirable to provide a detachable base of a display to mitigate and/or obviate the aforementioned problems.  
     SUMMARY OF THE INVENTION  
      A main objective of the present invention is to provide a detachable base of a display, which is easy to assemble and disassemble, so that the display can be detached from the base to reduce the packing space for easier transportation.  
      In order to achieve the above mentioned objective, the detachable base comprises a connecting body mounted on a display body, a bottom face of the connecting body having at least one first sliding mechanism and a first retaining mechanism; and an undercarriage correspondingly mounted on the bottom face of the connecting body, the undercarriage having at least one second sliding mechanism and an operating section, wherein the at least one second sliding mechanism comprises an inlet end and a stop end, the operating section comprises an elastic region and an operating region, and the operating region is located at a free end of the elastic region and another end of the elastic region is fixed on the undercarriage; wherein the at least one first sliding mechanism of the connecting body is capable of sliding into the inlet end of the at least one second sliding mechanism until reaching the stop end, and the first retaining mechanism correspondingly retains the operating region of the operating section.  
      Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      A detachable base of a display of the present invention is suitable for a flat panel display, such as an LCD (liquid crystal display), FTD (field transmit display) or a plasma display. In the present invention, a second sliding mechanism can be a slot, and a first sliding mechanism can be a sliding segment that is capable of sliding into the slot. A first retaining mechanism can be a stopping segment that correspondingly pushes an operating region of an operating section of an undercarriage. There are preferably four first sliding mechanisms and four second sliding mechanisms. A free end of the elastic region of the operating section of the undercarriage connects to the undercarriage, and both are integrated together. The location of the first sliding mechanism and the first retaining mechanism are unlimited; preferably, the first sliding mechanisms are symmetrically located on the bottom face of the connecting body, and the first retaining mechanism is located in the center of the bottom face. The operating region of the operating section is a sheet-like element, which can be pushed by a human finger. The detachable base of the present invention is easy to assemble and disassemble, so that the display can be detached from the base to reduce the space requirements for packing, making for easier shipping.  
      An embodiment is provided in the following for further explanation.  
      Please refer to  FIG. 1 ,  FIG. 2A ,  FIG. 2B , and  FIG. 3 . In this embodiment, the base is attached to a display; the base comprises a connecting body  100  and an undercarriage  200 . The connecting body  100  is mounted on the display, and a bottom face  101  of the connecting body  100  has four first sliding mechanisms  120  (which are four L-shaped segments) and a first retaining mechanism  130  (which is a stopping segment). The undercarriage  200  is correspondingly mounted on the bottom face  101  of the connecting body  100 , having four second sliding mechanisms  210  (which are four slots) and an operating section  220 . The second sliding mechanisms  210 , positioned corresponding to the first sliding mechanisms  120  of the connecting body  100 , have inlet ends  211  and stop ends  212 . The first sliding mechanisms  120  of the connecting body  100  are able to slide relative to the second sliding mechanisms  210 . The operating section  220  comprises an elastic region  221  and an operating region  222 , and the operating region  222  is located at a free end of the elastic region  221 . The other end of the elastic region  221  is fixed on the undercarriage  200 .  
      During assembly, the connecting body  100  is moved to slide the first sliding mechanisms  120  of the connecting body  100  from the inlet end  211  of the second sliding mechanisms  210  to the stop end  212  of the second sliding mechanisms  210 . Meanwhile, the first retaining mechanism  130  of the connecting body  100  is moved from the elastic region  221  of the operating section  220  and pushes against the operating region  222  of the operating section  220 . Therefore, the first sliding mechanisms  120  of the connecting body  100  become fixed in the stop end  212  of the second sliding mechanisms  210 , and the first retaining mechanism  130  of the connecting body  100  pushes against the operating region  222  of the operating section  220 ; consequently, the connecting body  100  is fixed on the undercarriage  200  to finish the assembly process.  
      During disassembly, the operating region  222  of the operating section  220  is flipped (for example, by a human finger), so that an elastic force provided by the elastic region  221  of the operating section  220  causes the operating region  222  to leave the first retaining mechanism  130  of the connecting body  100 . The connecting body  100  thus slides in an opposite direction on the undercarriage  200 . Meanwhile, the first retaining mechanism  130  of the connecting body  100  moves back to the elastic region  221  of the operating section  220  to separate the connecting body  100  from the undercarriage  200 .  
      The detachable base of the present invention is easy to assemble and disassemble, so the display can be easily detached from the base to reduce packing space requirements for easier transportation.  
      Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
