Description:
BACKGROUND OF THE INVENTION 
       [0001]    (1) Field of the Invention 
         [0002]    The invention relates to an angle-adjustable display holder composed of a first adjusting mechanism, a frame, a second adjusting mechanism and a third adjusting mechanism. Moving the first adjusting mechanism may move the display holder leftwards or rightwards. Moving the second adjusting mechanism may move a display held by the holder leftwards or rightwards. Moving the third adjusting mechanism can adjust an angle of the display. 
         [0003]    (2) Description of the Prior Art 
         [0004]    Displays may be applied to various applications, such as a television, a computer, a vehicle, a VCD or a DVD. However, most of the displays in various occasions are fixed, and the positions, the directions and the angles thereof cannot be adjusted. Even if some displays can be adjusted, only the positions, the directions or the angles can be adjusted. No mechanism can have the functions of adjusting the position, the direction and the angle. Although many manufacturers have spent a lot of spirit and resources to do the research and development, no definite effect is obtained. 
       SUMMARY OF THE INVENTION 
       [0005]    Although many manufacturers have spent a lot of time to improve the above-mentioned drawback, no effective method has been provided to overcome this drawback. In view of this, the present inventor has spent a lot of time and spirit to do improvements, tests and experiments according to various marketing experiences to provide an angle-adjustable display holder capable of solving the above-mentioned problem. 
         [0006]    A main object of the invention is to provide an angle-adjustable display holder, which is mainly composed of a first adjusting mechanism, a frame, a second adjusting mechanism and a third adjusting mechanism. The first adjusting mechanism is composed of a rotatable head, fitting covers and a shaft rod. Upper and lower ends of the rotatable head are formed with shaft holes, and one side of the rotatable head is formed with an accommodating slot. Central portions of the fitting covers are formed with shaft holes. The shaft rod is fixed on a mounting seat. Moving the first adjusting mechanism can move the overall display holder leftwards or rightwards. 
         [0007]    Another object of the invention is to provide an angle-adjustable display holder, wherein the second adjusting mechanism is composed of a shaft block and a pivoting block. The shaft block is formed with a shaft hole, and the pivoting block is formed with a shaft accommodating slot and a shaft hole. Moving the second adjusting mechanism can move a display held by the holder leftwards or rightwards. 
         [0008]    Still another object of the invention is to provide an angle-adjustable display holder, wherein the third adjusting mechanism is composed of a base, a universal joint and an adjusting shaft seat. The base and the adjusting shaft seat are formed with arced slots for supporting and accommodating the universal joint. Moving the third adjusting mechanism can adjust an angle of the display. 
         [0009]    Further aspects, objects, and desirable features of the invention will be better understood from the detailed description and drawings that follow in which various embodiments of the disclosed invention are illustrated by way of examples.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0016]      FIG. 1  is a pictorially exploded view showing an angle-adjustable display holder according to the invention. As shown in  FIG. 1 , the display holder is mainly composed of a first adjusting mechanism  1 , a frame  2 , a second adjusting mechanism  3  and a third adjusting mechanism  4 . The first adjusting mechanism  1  is composed of a rotatable head  11 , two fitting covers  12 ,  12 ′ and one shaft rod  13 . The rotatable head  11  has upper and lower ends respectively formed with shaft holes  111 ,  111 ′, and a lateral side formed with an accommodating slot  112 . Central portions of the fitting covers  12 ,  12 ′ are also formed with shaft holes  121 ,  121 ′. The shaft rod  13  is fixed on a mounting seat A. One end of the frame  2  is formed with a shaft hole  21 , and the other end of the frame  2  is formed with an accommodating slot  22 . The second adjusting mechanism  3  is composed of a shaft block  31  and a pivoting block  32 . The shaft block  31  is formed with a shaft hole  311 , and the pivoting block  32  is formed with a shaft accommodating slot  33  and a shaft hole  321 . A rear side of the pivoting block  32  is formed with a screw hole  322 . The third adjusting mechanism  4  is composed of a base  41 , a universal joint  42  and an adjusting shaft seat  43 . The base  41  and the adjusting shaft seat  43  are formed with arced slots  411  for supporting and accommodating the universal joint  42 . 
         [0017]      FIGS. 2 and 3  are respectively a pictorially assembled view and an assembled cross-sectional view showing the display holder according to the invention. As shown in  FIGS. 2 and 3 , when the display holder is being assembled, one end of the frame  2  is inserted into the accommodating slot  112  of the rotatable head  11  of the first adjusting mechanism  1 , and the fitting covers  12 ,  12 ′ are respectively fit with the upper and lower ends of the rotatable head  11  so that the shaft holes  121 ,  121 ′,  111 ,  111 ′,  21  of the fitting covers  12 ,  12 ′, the rotatable head  11  and the frame  2  correspond to one another, and then the shaft rod  13  fixed on the mounting seat A penetrates through the shaft holes  121 ,  121 ′,  111 ,  111 ′,  21  and is then screwed. In addition, one end of the shaft block  31  of the second adjusting mechanism  3  is fixed into the accommodating slot  22  on the other end of the frame  2 , and the other end of the shaft block  31  is inserted into the shaft accommodating slot  33  of the pivoting block  32  so that the shaft holes  311  and  321  of the shaft block  31  and the pivoting block  32  correspond to each other and a pivot pin  34  penetrates through the shaft holes  311  and  321  and then is screwed. The universal joint  42  of the third adjusting mechanism  4  is placed in the arced slot  411  of the base  41 , and a screw is provided to screw the universal joint  42  and the base  41  to the screw hole  322  on the rear side of the pivoting block  32  of the second adjusting mechanism  3 . The adjusting shaft seat  43  of the third adjusting mechanism  4  fits with the universal joint  42  so that the arced slot of the adjusting shaft seat  43  and the universal joint  42  can be combined, and then a display seat B is screwed to the adjusting shaft seat  43 . 
         [0018]    As shown in  FIG. 4 , when the display holder is to be totally moved leftwards or rightwards, the frame  2  is directly moved. Because one end of the frame  2  is placed in the accommodating slot  112  of the rotatable head  11  of the first adjusting mechanism  1  and the shaft rod  13  penetrates through the one end of the frame  2 , the rotatable head  11  of the first adjusting mechanism  1  can be rotated about the shaft rod  13  so that the frame  2  may be moved leftwards or rightwards. When a display held by the holder is to be moved leftwards or rightwards, the display may be directly moved. In this case, the pivot pin  34  of the second adjusting mechanism  3  penetrates through the pivoting block  32  and the shaft block  31 , so the pivoting block  32  is rotated about the pivot pin  34  and the display can be moved leftwards or rightwards, as shown in  FIG. 5 . When an angle of the display has to be adjusted, because the universal joint  42  of the third adjusting mechanism  4  has a circular arc surface and contacts the arced slot of the adjusting shaft seat  43 , the display can be directly moved so that the angle of the display can be adjusted.
