Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a supporting shelf, and more particularly, to a wall-supported shelf designed for supporting an LCD TV in an upright, erect position.  
         [0003]     2. Description of the Related Art  
         [0004]     Today, in order to satisfy consumers&#39; enjoyment of TV or movies, many restaurants and bars set an LCD TV on a wall of their business place so that their customers can watch something while they are waiting for or enjoying their meal. However, the conventional way to set an LCD TV on the wall is through a conventional supporting shelf. An end face of the supporting shelf is fixed onto the wall, and the LCD TV is fixed at a further end face of the supporting shelf. Although attaching the LCD TV onto the wall satisfies the customers&#39; desire to watch TV, due to the fixed position of the LCD TV, it cannot be moved. Aside from demounting the supporting shelf, and then resetting it at a position there is no way to adjust the position of the TV. But such a procedure is extremely time-consuming and inconvenient.  
       SUMMARY OF THE INVENTION  
       [0005]     It is therefore a principal objective of the present invention to provide an easily demounted and easily remounted wall-supported shelf designed for supporting an LCD TV in an upright, erect position.  
         [0006]     Furthermore, a further objective of the present invention is to provide a wall-supported shelf having an adjustable viewing angle so that the viewing angle of the LCD TV may be changed. The present invention has been accomplished to eliminate the aforesaid problem.  
         [0007]     To achieve the above objective, one feature of the present invention provides a supported shelf, including at least one fixing seat having a fixing shelf for connecting to a base seat, and having a side face thereof for connecting to a firm place; and at least one fixing rod having a side face for connecting to the fixing seat, and having a further side face thereof for connecting to a side face of an object such as an LCD TV.  
         [0008]     To provide further understanding of the invention, the following detail description illustrates embodiments and examples of the invention, this detailed description being provided only for illustration of the invention.

       [0016]     Referring now to the attached drawings that are shown are for the purposes of illustrating the preferred embodiments of the present invention only, and not for the purposes of limiting the same.  
         [0017]     Please refer to FIGS.  1  to.  4  that show the present invention of a supporting shelf including a fixing seat  1  and a fixing rod  2 .  
         [0018]     The fixing seat  1  has a fixing shelf  11  and a base seat  12 . The fixing shelf  11  connects to the base seat wherein the fixing shelf has a square shape. An opening is defined on the fixing shelf. Two crossing shelves, which are a first cross-shelf  111  and a second cross-shelf  113 , are formed respectively on two opposite side edges of the opening. The two crossing shelves  111  and  113  are provided for the fixing rod  2  to be erected upon. Two connecting pieces, which are a first bent connecting piece  112  and a second bent connecting piece  114 , are bent to form respectively on two further opposite side edges of the opening. Each of the two bent connecting pieces  112  and  114  is defined with a plurality of fixing holes. The base seat  12  has a base side  121 . The base side  121  has a plurality of fixing holes  1211 . The fixing holes  1211  are provided respectively for a plurality of fixing elements to attach the base seat  12  onto the wall, so that a side face of the fixing shelf  11  connects to a firm place, such as a wall  3  as shown in  FIG. 4 . Two sidewalls, which are a first sidewall  122  and a second sidewall  123 , are formed respectively on two opposite side edges of the base side  121 . Each of the two sidewalls  122  and  123  is respectively defined with a first sliding groove  1221  and a second sliding groove  1223 . A first positioning part  1222  is formed on a perimeter edge of the first sliding groove  1221 . A second positioning part  1224  is formed on a perimeter edge of the second sliding groove  1223 . Each of the two bent connecting pieces  112  and  114  is connected respectively to each of the two sidewalls  122  and  123 . The fixing seat  1  further comprises two connecting bars, which are a first connecting bar  13  and a second connecting bar  15 . Each of the two connecting bars  13  and  15  has an end pivotally connecting to each of the two sidewalls  122  and  123  of the base seat  12 . Each of the two connecting bars  13  and  15  has a further end pivotally connecting to each of the bent connecting pieces  112  and  114  of the fixing shelf  11  through two pivots. The two pivots are a first pivot  14  and a second pivot  16 . Each of the two pivots  14  and  16  is disposed in each of the two sliding grooves  1221  and  1223 . Each of the two positioning parts  1222  and  1224  is formed on the perimeter edge of each of the two sliding grooves  1221  and  1223  and provides a positioning function for each of the two pivots  14  and  16 . Hence, each of the two positioning parts  1222  and  1224  is to be used for increasing the resistance of each of the two pivots  14  and  16  in each of the two sliding grooves  1221  and  1223 . In this way, both the fixing shelf  11  and the base seat  12  have a reciprocating motion between each other through the arrangement of the two connecting bars  13  and  15  and the two sliding grooves  1221  and  1223 .  
         [0019]     The fixing rod  2  has a side face connecting to the fixing seat  1 . A further side face of the fixing rod  2  connects to a side face of an object, such as an LCD TV  4 . The fixing rod  2  has a casing  21  and a retaining element  22 . The retaining element  22  is disposed on the casing  21 . The casing  21  is an open casing with the shape of a rectangle. The casing  21  has a base side  211 . The base side  211  is defined with a plurality of fixing grooves  2111 . The fixing grooves  2111  are provided for a plurality of fixing elements to attach the LCD TV  4  onto. Because each of the fixing grooves  2111  is longitudinally shaped, the fixing elements according to the different size of the LCD TV are moved in the fixing grooves  2111  for proper adjustment. Two sidewalls  212  and  213  are formed respectively on two opposite side edges of the base side  211 . Each of the two sidewalls  212  and  213  has a hook  2121  mounted on the first cross-shelf  111  of the fixing shelf  11 . Furthermore, the retaining element  22  has an adjusting rod  221  connected to a retaining part  222  with an end thereof. A further end of the adjusting rod  221  is connected to a knob  223 . The knob  223  is provided so that a user can conveniently adjust the adjusting rod  221  of the retaining element  22 . The retaining part  222  has two opposing grooves, which are a first groove  2221  and a second groove  2222 , mounted to a further one of the two cross shelves, which is the second cross-shelf  113  of the fixing shelf  11 . The LCD TV  4  connected to the fixing rod  2  is erected on the two cross shelves  111  and  113  of the fixing seat  1 , as shown in  FIG. 4 . If the user wants to demount the LCD TV  4  erected on the fixing rod  2 , they just need to adjust the adjusting rod  221  of the retaining element  22  to accomplishing demounting.  
         [0020]     Referring to  FIG. 5 , which is a perspective view of a pair of the preferred embodiments of the present invention disposed with a liquid crystal display TV attached. When actually using the present invention to attach an object, such as an LCD TV, to a firm point, not only a single fixing seat  1  and a single fixing rod  2  can be applied. A plurality of fixing seats and fixing rods of the present invention can also be applied.  
         [0021]     Please refer to  FIG. 6  that is a side view of a further preferred embodiment of the present. The fixing shelf  11  and the base seat  12  are formed of a piece of metal, so the base seat  12  is integrally formed with the fixing shelf  11 . The other configuration is the same as the aforesaid present invention.  
         [0022]     So, the present invention has the following characteristics:  
         [0023]     1) The fixing seat  1  comprises two connecting bars, which are a first connecting bar  13  and a second connecting bar  15 .

Each of the two connecting bars  13  and  15  has a further end pivotally connecting to each of the bent connecting pieces  112  and  114  of the fixing shelf  11  through two pivots. The two pivots are a first pivot  14  and a second pivot  16 . Each of the pivots  14  and  16  is disposed in each of the two sliding grooves  1221  and  1223 , hence both the fixing shelf  11  and the base seat  12  have a reciprocating motion between each other through the arrangement of the two connecting bars  13  and  15  and the two sliding grooves  1221  and  1223 , for adjusting the viewing angle of the LCD TV  4  erected on the fixing rod  2 .  
         [0024]     2) The retaining element  22  has an adjusting rod  221  connected to a retaining part  222  with an end thereof. A further end of the adjusting rod  221  is connected to a knob  223 . The knob  223  is provided so that a user can conveniently adjust the adjusting rod  221  of the retaining element  22 . The retaining part  222  has two opposing grooves, which are a first groove  2221  and a second groove  2222 , mounted to a further one of the two cross shelves, the other one of the two cross shelves is the second cross-shelf  113  of the fixing shelf  11 . The LCD TV  4  connected to the fixing rod  2  is erected on the two cross shelves  111  and  113  of the fixing seat  1 , as shown in  FIG. 4 . If the user wants to demount the LCD TV  4  erected on the fixing rod  2 , they just need to adjust the adjusting rod  221  of the retaining element  22  to accomplish demounting.  
         [0025]     There has thus been described a new, novel and heretofore unobvious supporting shelf eliminating the aforesaid problem of the prior art. Furthermore, those skilled in the art will readily appreciate that the above description is only illustrative of specific embodiments and examples of the invention. The invention should therefore cover various modifications and variations made to the herein-described structure and operations of the invention, provided they fall within the scope of the invention as defined in the following appended claims.
