Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an angle adjusting device for a display, which is mounted on a rear surface of a display to suspend the display onto a main support bracket, and more particularly to an angle adjusting device for a display which adjusts an angle according to a viewing angle, and effectively secures the display. 
         [0003]    2. Related Art 
         [0004]    Currently, the display has formally transitioned from the conventional CRT type to a digital type, and plasma and liquid crystal displays are dominant in the current market, especially the liquid crystal displays are more accepted. In addition to the advantages of more abundant colors and low radiation, the panel used in the display is thinned, which completely meets the requirements for thinner products. For the applications of the display, for example, the liquid crystal display connected to a computer host, the liquid crystal television, and the plasma television are all products having quite high homogeneity, and can be substantially divided into desktop, wall mounted, and suspended displays depending on the mounting methods and positions in actual use. For example, the desktop display is provided with a support seat on the rear surface, so that the display can be firmly placed on a plane by the support seat; however, the wall mounted or suspended display needs a main support bracket, so as to secure the display to the main support bracket through suspension. Furthermore, according to requirements in actual use, the main support bracket can be secured to a wall (wall mounted), or be further provided with a connecting rod, so as to be disposed on a ceiling (suspended), or a side surface of a cantilever (suspended). At present, the methods for mounting the wall mounted or suspended display screen may use two types of suspension devices, one is a suspension device with a fixed angle, and the other is a suspension device with an adjustable angle. The suspension device with a fixed angle is frequently used in suspension to a wall, that is, the angle of the suspension device is fixed, for example, parallel to the wall (that is, 0 degrees), or at 5 degrees to the wall. Therefore, the suspension of the display must consider the angle of the suspension device. The other type is the suspension device with an adjustable angle, which is often formed as a whole set of angle adjusting seat conventionally, so it has a large volume, high weight complicated structure, relatively high production cost, and is inconvenient to assemble and use for common consumers due to the complicated structure. 
       SUMMARY OF THE INVENTION 
       [0005]    Accordingly, the present invention is directed to an angle adjusting device for a display, which has a simple structure, is easy to operate, and is cost effective. 
         [0006]    To achieve the above objective, the present invention provides a support bracket, which is mounted on a rear surface of a display, and has more than one hook formed on a body thereof so as to meet requirements for mounting at a specific angle. A first connecting rod and a second connecting rod are further formed on the body of the support bracket so to meet requirements for adjustable mounting angles by adjusting positions of the first connecting rod and the second connecting rod.

Two sides at the other end of the second connecting rod  103  can be secured to a chute  10124  formed in a plane near the top of the two wing parts ( 1012 ,  1013 ). 
         [0017]      FIG. 2  is a schematic view of a structure according to the present invention. As shown in  FIG. 2 , the support bracket  101  is provided with a mounting plane  1101 , two edges of which are bent to form a first wing part  1012  and a second wing part  1013  respectively at corresponding positions. The two wing parts ( 1012 ,  1013 ) are formed with a first upper hook ( 10121 ,  10131 ) and a first lower hook ( 10122 ,  10132 ) respectively. The two first upper hooks ( 10121 ,  10131 ) are at corresponding positions, and the two first lower hooks ( 10122 ,  10132 ) are also at corresponding positions. In addition, a plane near the two first lower hooks ( 10122 ,  10132 ) of the two wing parts ( 1012 ,  1013 ) is formed with a first pivotal part ( 10123 ,  10133 ) respectively. Furthermore, a chute ( 10124 ,  10134 ) is respectively formed in a plane near the top of the two wing parts ( 1012 ,  1013 ), and more than one hook hole ( 10125 ,  10135 ) is respectively formed on the sides of the two chutes ( 10124 ,  10134 ), which are in communication with the chutes ( 10124 ,  10134 ) respectively. The first connecting rod  102  has a body  1021 , which has a second upper hook  1022  formed at the two sides of the upper edge, and a second lower hook  1023  formed at the two sides of the lower edge. Furthermore, a first relative pivotal part  10221  is formed on a plane of the second lower hook  1023 , and a second pivotal part  10211  is formed at the plane near the second upper hook  1022 . Referring to  FIG. 2  again, the two sides at one end of the second connecting rod  103  are respectively formed with a second relative pivotal part  1031 , and the other end is formed with a third pivotal part  1032 . In the mounting, the first relative pivotal part  10221  of the first connecting rod  102  is relatively pivoted to the first pivotal part  10123  of the support bracket  101 , and the second pivotal part  10211  of the first connecting rod  102  is relatively pivoted to the second relative pivotal part  1031  of the second connecting rod  103 . Furthermore, a fixing screw  104  passes through the chute  10124  of the support bracket  101 , and then through the third pivotal part  1032  of the second connecting rod  103 . Thus, the mounting is completed as shown in  FIG. 1 . 
         [0018]      FIG. 3  is a first schematic view of an embodiment of the present invention. As shown in  FIG. 3 , the angle adjusting device  10  for a display of the present invention can be mounted on a rear surface of a display  20 . In the implementation, a pair of angle adjusting devices  10  may be mounted on the rear surface of the display  20  at suitable positions evenly. Furthermore, for mounting at a specific position, a main support bracket  30  is further provided. Upper and lower edges of the main support bracket  30  are formed with an upper hook edge  301  and a lower hook edge  302 . As such, in the mounting, the display  20  can be suspended on the main support bracket  30  by the angle adjusting device  10  for a display assembled in advance. In the suspension, each pair of upper hooks  10121  of the angle adjusting device  10  for a display is hooked onto the upper hook edge  301  of the main support bracket  30 , and each pair of lower hooks  10122  of the angle adjusting device  10  for a display is hooked onto the lower hook edge  302  of the main support bracket  30 . 
         [0019]      FIG. 4  is a second schematic view of the embodiment of the present invention. As shown in  FIG. 4 , the main support bracket  30  is secured to a wall  50  in advance by a relative support bracket  40  disposed on the rear surface thereof, or is directly secured to the wall  50  by screws.  FIG. 4  shows a first use of the present invention, in which the display  20  is parallel to the wall  50  after mounting, that is, the angle between the display  20  and the wall  50  is 0 degrees after mounting. As shown in  FIG. 4 , in the implementation, the device of the present invention is mounted the rear surface of the display  20  in advance, and is hooked onto the upper hook edge  301  of the main support bracket  30  by the first upper hooks ( 10121 ,  10131 ) formed on the support bracket  101 , and onto the lower hook edge  302  of the main support bracket  30  by the first lower hooks ( 10122 ,  10132 ) of the support bracket  101 .  FIG. 5  is a third schematic view of the embodiment according to the present invention; as described above, the display  20  is effectively secured and parallel to the wall  50  after mounting. 
         [0020]      FIG. 6  is a fourth schematic view of the embodiment of the present invention. As shown in  FIG. 6 , it is intended to secure the display  20  is parallel to the wall  50  at the angle of 0 degrees, the second upper hook  1022  and the second lower hook  1023  of the first connecting rod  102  can also be selected to hook onto the upper hook edge  301  and the lower hook edge  302  of the main support bracket  30  respectively. As such, the distance from the rear surface of the display  20  to the main support bracket  30  is increased, that is, a larger accommodation space  60  is formed between the main support bracket  30  and the rear surface of the display  20  to accommodate a related electronic apparatus  70 , such as a digital TV box or micro-computer. 
         [0021]      FIG. 7  is a fifth schematic view of the embodiment of the present invention. When it is intended to mount the display  20  at a higher position, the plane of the display  20  is generally required to incline downward to a suitable angle, for example, 5 or 10 degrees. Therefore, in an application of the present invention, the angle adjusting device  10  for a display can be adjusted to a suitable angle first as shown in  FIG. 7 . Then, according to the actual angle required, the fixing screw  104  is loosened and moved along the chutes ( 10124 ,  10134 ) to the suitable hook holes ( 10125 ,  10135 ). After the position is confirmed, the fixing screw  104  is fastened. In the movement along the chutes ( 10124 ,  10134 ), the second connecting rod  103  and the first connecting rod  102  also driven to move, and after the adjustment, the support bracket  101  is tilted. In the mounting, the second upper hook  1022  and the second lower hook  1023  of the first connecting rod  102  are hooked onto the upper hook edge  301  and the lower hook edge  302  of the main support bracket  30  respectively to effectively secure the display  20 . The display  20  is at a suitable angle with respect to the wall  50  after securing. Referring to  FIGS. 6 and 7  for another operation mode, if the display  20  is mounted at angle of 0 degrees originally, and needs to be adjusted to another angle, the display  20  does not need to be disassembled. Firstly, the fixing screw  104  is loosened slightly. Then, an operator only needs to slightly apply a force onto the top the display  20  downwardly because the first connecting rod  102  and the main support bracket  30  are in a mounted state, such that the fixing screw  104  is moved to a hook hole ( 10125 ,  10135 ), and thus the display  20  is tilted downward to a suitable angle due to the interlock effect. When the display  20  is tilted to a suitable position, the fixing screw  104  is fastened again, so as to be fixed in the hook hole ( 10125 ,  10135 ). Thus, the operation is completed. As described above, in the present invention, the staged angle adjustment of the display  20  can be achieved due to the different positions of the hook holes ( 10125 ,  10135 ) based on the distance between hook holes ( 10125 ,  10135 ). For example, the first hook hole can be designed to achieve a tilt angle of  5  degrees, and the second hook hole can be designed to achieve a tilt angle of  10  degrees, and so on. 
         [0022]      FIG. 8  is a sixth schematic view of the embodiment of the present invention. As shown in  FIG. 8 , stageless adjustment can be achieved in the operation of the angle adjusting device  10  for a display of the present invention. The stageless adjustment means adjustment not limited to specific angles, in which through the chute  10124  of the present invention, the fixing screw  104  can be fixed at any position in the movement path of the chute  10124  to achieve the adjustment at unspecific angles, and improve the practicality of the whole system. 
         [0023]    As described above, the present invention achieves the staged or stageless angle adjustment of the display according to actual mounting requirements through connecting rod interlocking. To sum up, the present invention can achieve the purposes of providing an angle adjusting device for a display that has a simple structure, is easy to operate and is cost effective according to the embodiments of the present invention, 
         [0024]    However, it is understood that the descriptions above are only the preferable embodiments of the present invention, and not intended to limit the scope of the present invention. All equivalent modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention shall fall into the claims of the present invention.
