Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a mobile navigator; more particularly, relates to improving a robustness of a supporting element of the navigator.  
       DESCRIPTION OF THE RELATED ART  
       [0002]     As shown in  FIG. 7  and  FIG. 8 , a general mobile navigator uses a supporting frame  4 , comprising a first frame  41  and a second frame  42 . A shaft  411  is set at the center of the first frame  41 , where a socket part  412  is deposed on an end surface of the shaft  411  and first cantilever beams  413  are set at two sides of the shaft  411 . A receiving hole  414  is located at an end surface of the first cantilever beam  413 ; a supporting plate  415  is set at a side of the first cantilever beam  413  near the receiving hole  414 ; and, a through hole  416  is located on the supporting plate  415 . A receptacle  421  is set at center of the second frame  42 , where a connection hole  422 , corresponding to the socket part  412 , is deposed on an end surface of the receptacle  421  and second cantilever beams  423  are set at two sides of the receptacle  421 . A protruding column  424 , corresponding to the receiving hole  414  of the first cantilever beam  413 , is located at an end surface of the second cantilever beam  423 ; a hook  425  is set at a side of the second cantilever beam  423  near the protruding column  424 ; and, the hook  425  is locked to the through hole  416  on the supporting plate  415 . Thus, a supporting frame  4  used in a general mobile navigator is formed.  
         [0003]     Because the supporting frame  4  of the prior art is formed by solely inserting the socket part  412 , the protruding column  424  and the hook  425  into the connection hole  422 , the receiving hole  414  and the through hole  416 , the robustness of the supporting frame  4  is not strong. When a down force is exerted onto the supporting frame  4  in use, the support for the first and the second frames  41 ,  42  may not be enough and so the frames  41 ,  42  may be broken apart at the place where the frames  41 ,  42  connect to each other originally. Additionally, the structure of the prior art is complex and so is not assembled easily together with some problems quite often happened on assembling the prior art. Hence, the prior art does not fulfill users&#39; requests on actual use.  
       SUMMARY OF THE INVENTION  
       [0004]     The main purpose of the present invention is to easily assemble a supporting element of a mobile navigator and to improve a robustness of the supporting element.  
         [0005]     To achieve the above purpose, the present invention is a mobile navigator having locked braces, comprising a metal cylinder, a supporting element and a plurality of terminals, where the supporting element comprises a first brace and a second brace; each of the two braces has a shaft to be sheathed with the metal cylinder; an assembling element is deposed on an end surface of one shaft and a corresponding assembling hole is located on an end surface of the other shaft; two cantilever beams are set at two sides of each shaft; two locking parts are respectively deposed on two end surfaces of two cantilever beams and corresponding locking holes are located on two end surfaces of the other two cantilever beams; and the terminals are fixed on the supporting element. Accordingly, a novel mobile navigator having locked braces is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0014]     The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.  
         [0015]     Please refer to  FIG. 1  till  FIG. 4 , which are a perspective and a structural views showing a preferred embodiment and perspective views showing its braces, according to the present invention. As shown in the figures, the present invention is a mobile navigator having locked braces, comprising a metal cylinder  1 , a supporting element  2  and a plurality of terminals  3 , where the components are easily assembled and the robustness of the supporting element  2  is improved by inserting an assembling element  212  into a corresponding assembling hole  222  and by locking locking parts  214  to corresponding locking holes  224 .  
         [0016]     The metal cylinder  1  is a hollow cylinder. The supporting element  2  comprises a first brace  21  and a second brace  22  to fix the metal cylinder  1 . Each of the braces  21 ,  22  has a shaft  211 ,  221  at center to be sheathed with the metal cylinder  1 . An assembling element  212  of a protruding column is deposed on an end surface of one shaft  211 . An assembling hole  222  corresponding to the assembling element  212  is deposed on an end surface of the other shaft  221 . Each shaft  211 ,  221  has two cantilever beams  213 ,  223  at two sides of the shaft  211 ,  221 . Two cantilever beams  213  of one shaft  211  have a locking part  214  at an end surface of each cantilever beam  213 . The locking part  214  has a hook  215  slightly sloping toward a side at an end of the locking part  214 . Two cantilever beams  223  of the other shaft  221  have a locking hole  224  at an end surface of the cantilever beam  223 . The locking hole  224  has a slot  225  on a side wall of the locking hole  224 . The terminals  3  are fixed on the supporting element  2 . Each terminal  3  has a contactor  31  inserted into the metal cylinder  1  from either end surface of the metal cylinder  1  to be contacted with the inner surface of the metal cylinder  1 . Hence, with the above structure, a novel mobile navigator having locked braces is obtained.  
         [0017]     Please refer to  FIG. 5  and  FIG. 6 , which are a view showing an assembly of the preferred embodiment and its sectional view. As shown in the figures, when assembling a first and a second braces  21 ,  22  of a supporting element  2 , an assembling element  212 , being a protruding column, of a shaft  211  on the first brace  21  is inserted into an assembling hole  222  of another shaft  221  on the second brace  22 ; and, at he same time, locking parts  214  deposed respectively on two end surfaces of two cantilever beams  213  are respectively inserted into corresponding locking holes  224  on two end surfaces of the other two cantilever beams  223 . In addition, a hook  215  at a side of the locking part  214  is locked to a corresponding slot  225  at a side wall of the locking hole  224 . Thus, the first and the second braces are easily assembled for obtaining the supporting element  2 . Besides, by inserting the assembling element  212  and the locking parts  214  into the assembling hole  222  and the locking holes  224  respectively and by solving assembly problems through the guidance of the hooks  215  of the locking parts  214 , the entire supporting element  2  obtains a strong support and its robustness is improved as well. In the other hand, a slot  225   a  can also be set on a surface of the cantilever beam  223  to be locked with a proper hook  215 .

Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
