Description:
BACKGROUND  
       [0001]     The invention relates to an electronic apparatus, and in particular to an electronic apparatus providing rapid assembly/disassembly and height adjustment functions.  
         [0002]     A thin TV or display often comprises a monitor and a pedestal. The thin TV or display is assembled by fastening bolts to the monitor and pedestal.  
         [0003]     A few drawbacks exist when the monitor is fixed to the pedestal by bolts. As the size of the thin TVs (or monitors) increases, the weight thereof increases correspondingly. When a thin TV or display is assembled, the monitor and pedestal are often placed at a sloped angle or horizontally. The display panel of the monitor is thus easily scraped or damaged. In another aspect, when the monitor and pedestal are not placed at a sloped angle or horizontally, at least two operators are required to assemble the thin TV or display, thereby increasing the number of laborers. Moreover, a screwdriver is required for assembly of the monitor and pedestal, causing inconvenience. Furthermore, when the height of the thin TV (or monitor) is adjusted, the bolts must be removed from the monitor and pedestal. The bolts are again fastened to the monitor and pedestal after the height of the thin TV (or monitor) is adjusted, further increasing complexity of height adjustment.  
       SUMMARY  
       [0004]     Accordingly, an exemplary embodiment of the invention provides an electronic apparatus providing height adjustment functions. The electronic apparatus comprises a pedestal, a main body, and a positioning mechanism. The pedestal comprises a guiding member. The main body is detachably connected to the guiding member and comprises a guiding groove located in which the guiding member relatively slides. The positioning mechanism is movably disposed in the guiding member and guiding groove to control the sliding position of the guiding member with respect to the guiding groove.  
         [0005]     In an embodiment of the electronic apparatus, the guiding member further comprises a first through hole. The guiding groove further comprises at least one positioning hole. The positioning mechanism engages the positioning hole via the first through hole, controlling the sliding position of the guiding member with respect to the guiding groove.  
         [0006]     In an embodiment of the electronic apparatus, the guiding member further comprises a second through hole. The positioning mechanism further comprises an engaging member, a resilient member, and a retardant member. The second through hole is coaxially connected to the first through hole. The engaging member is disposed in the first and second through holes. The retardant member covers and is fixed on the second through hole. The resilient member is disposed in the second through hole and between the engaging member and the retardant member, providing resilience to the engaging member.  
         [0007]     In an embodiment of the electronic apparatus, the retardant member further comprises a third through hole and the engaging member further comprises a pillar, an abutting portion, and an engaging portion. The third through hole is coaxially connected to the second through hole. The abutting portion is between the pillar and the engaging portion and is disposed in the second through hole. The pillar is disposed in the second and third through holes and extends outside the third through hole. The engaging portion is disposed in and extends outside the first through hole, engaging the positioning hole. The resilient member is between the abutting portion and the retardant member and is disposed at the periphery of the pillar.  
         [0008]     In an embodiment of the electronic apparatus, the main body further comprises a guiding sloped surface connected to the guiding groove. The engaging portion engages the positioning hole by sliding on the guiding sloped surface and guiding groove.  
         [0009]     In an embodiment of the electronic apparatus, the resilient member comprises a spring.  
         [0010]     In an embodiment of the electronic apparatus, the cross sections of the guiding groove and guiding member are substantially the same.  
         [0011]     In an embodiment of the electronic apparatus, the main body comprises a monitor.

     DETAILED DESCRIPTION  
       [0020]     Referring to  FIG. 1  and  FIG. 2 , the electronic apparatus  100  comprises a pedestal  110 , a main body (monitor)  120 , and two positioning mechanisms  130 . The electronic apparatus  100  is, for example, a television. Although provided with two positioning mechanisms  130 , the electronic apparatus  100  is not limited to having two positioning mechanisms  130 . Namely, the electronic apparatus  100  may selectively comprise only one positioning mechanism  130 .  
         [0021]     The pedestal  110  comprises two opposing guiding members  111 . Each guiding member  111  comprises a first through hole  112  and a second through hole  113  coaxially connected to the first through hole  112 . In this embodiment, the diameter of the second through hole  113  exceeds that of the first through hole  112 . Specifically, the diameters of the first through hole  112  and second through hole  113  can be designed as required. Namely, the diameter of the second through hole  113  may be, alternatively, less than that of the first through hole  112 . Moreover, the profile of the pedestal  110  can be changed as required, and the pedestal  110  is not limited to having two opposing guiding members  111 . Namely, the pedestal  110  may selectively comprise only one guiding member  111 .  
         [0022]     The main body  120  is detachably connected to the guiding members  111  of the pedestal  110 . Specifically, the main body  120  comprises two guiding grooves  121  corresponding to the guiding members  111 . In this embodiment, the cross section of the guiding grooves  121  is substantially the same as that of the guiding members  111 . Additionally, each guiding groove  121  comprises a plurality of positioning holes ( 122   a ,  122   b ) formed therein and located on different levels. Moreover, the main body  120  comprises two guiding sloped surfaces  123  corresponding and connected to the guiding grooves  121 . Similarly, the main body  120  is not limited to having two guiding grooves  121  and two guiding sloped surfaces  123 . Alternatively, the main body  120  may selectively comprise only one guiding groove  121  and only one guiding sloped surface  123 .  
         [0023]     Moreover, when the main body  120  is a monitor, the guiding grooves  121  can be formed on the back of the monitor and a display panel (not shown) can be disposed on the front thereof.  
         [0024]     Each positioning mechanism  130  is movably disposed in each guiding member  111  of the pedestal  110  and each guiding groove  121  of the main body  120 . Specifically, each positioning mechanism  130  comprises an engaging member  131 , a resilient member  132 , and a retardant member  133 . As shown in  FIG. 2  and  FIG. 3 , the retardant member  133  covers and is fixed on the second through hole  113  of the guiding member  111 . Additionally, the retardant member  133  comprises a third through hole  133   a  coaxially connected to the second through hole  113 . The engaging member  131  comprises a pillar  131   a , an abutting portion  131   b , and an engaging portion  131   c . The abutting portion  131   b  is between the pillar  131   a  and the engaging portion  131   c  and is disposed in the second through hole  113 . The pillar  131   a  is disposed in the second through hole  113  and third through hole  133   a  of the retardant member  133  and extends outside the third through hole  133   a . The engaging portion  131   c  is disposed in the first through hole  112  and extends outside the first through hole  112 . The resilient member  132  is disposed in the second through hole  113  and between the abutting portion  131   b  of the engaging member  131  and the retardant member  133 . Specifically, the resilient member  132  is disposed at the periphery of the pillar  131   a  of the engaging member  131 . Accordingly, the engaging member  131  of the positioning mechanism  130  can move forward and backward, as indicated by arrow A of  FIG. 3 .  
         [0025]     Moreover, the resilient member  132  is, for example, a spring.  
         [0026]     The following description is directed to assembly and disassembly of the electronic apparatus  100  (such as a television).  
         [0027]     When the main body (monitor)  120  is positioned on the pedestal  110 , as shown in  FIG. 4 , the guiding grooves  121  of the main body  120  are respectively aimed at the guiding members  111  of the pedestal  110  and are moved downward (or relatively). As shown in  FIG. 5 , the guiding members  111  are simultaneously inserted into the corresponding guiding grooves  121 . At this point, the engaging portion  131   c  of each engaging member  131  slides on each guiding sloped surface  123  of the main body  120 . Then, the engaging portions  131   c  and guiding members  111  simultaneously slide in the guiding grooves  121 . Because of the profiles of the guiding grooves  121  and guiding members  111 , the engaging portions  131   c  of the engaging members  131  are pushed into (the second through holes  113  of) the guiding members  111 . At this point, the abutting portion  131   b  and pillar  131   a  of each engaging member  131  move toward the third through hole  133   a , and the resilient member  132  disposed between the abutting portion  131   b  and the retardant member  133  is compressed to provide resilience. The main body  120  continues to move downward until the engaging portion  131   c  of each engaging member  131  slide to the first positioning hole  122   a  in each guiding groove  121 . The engaging portion  131   c  rapidly ejects and engages the first positioning hole  122   a  by the resilience provided by the resilient member  132 , as shown in  FIG. 6 . At this point, the main body  120  and pedestal  110  are completely assembled.  
         [0028]     Moreover, when the height of the main body  120  relative to the pedestal  110  is adjusted, the engaging member  131  (or pillar  131   a ) can be pulled outward to separate the engaging portion  131   c  from the first positioning hole  122   a . At this point, the resilient member  132  disposed between the abutting portion  131   b  and the retardant member  133  is compressed to again provide resilience. The main body  120  is then moved downward and the engaging member  131  (or pillar  131   a ) is released. When the engaging portion  131   c  of each engaging member  131  slides to the second positioning hole  122   b  in each guiding groove  121 , the engaging portion  131   c  rapidly ejects and engages the second positioning hole  122   b  by the resilience provided by the resilient member  132 , as shown in  FIG. 7 . At this point, adjustment of the height of the main body  120  with respect to the pedestal  110  is complete. Specifically, the electronic apparatus  100  or main body  120  is not limited to having only two positioning holes  122   a  and  122   b . Namely, the main body  120  may selectively comprise more positioning holes in each guiding groove  121 , enabling different adjustment of the height of the main body  120  with respect to the pedestal  110 .  
         [0029]     In another aspect, when the main body  120  is separated from the pedestal  110 , the engaging member  131  (or pillar  131   a ) can be pulled out of the first positioning hole  122   a  or second positioning hole  122   b.  The main body  120  is then simultaneously moved upward (or relatively) until it is completely separated from the pedestal  110 .  
         [0030]     In conclusion, the electronic apparatus  100  can be rapidly assembled and disassembled, and the height thereof can be easily adjusted. Moreover, the electronic apparatus  100  can be rapidly assembled and disassembled in the absence of any assisting tool. Thus, troubles of missing of bolts are prevented.  
         [0031]     While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
