Abstract:
A skin is coated on a shell of a parallel device. With the skin, the parallel device becomes more beautiful. The skin is made of enamel. Hence, the shell is kept from scrape and corrosion. At the same time, the shell is more easily cleaned.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a skin for parallel device; more particularly, relates to beautifying appearance of parallel device accompanying a sense of feel with an enameled metal structure and thus being prevented from scrape and corrosion with easy cleaning. 
       DESCRIPTION OF THE RELATED ARTS 
       [0002]    A skin for parallel device is generally made of plastics, acrylon nitrile butadiene styrene (ABS) or polycarbonate (PC). But, a shell made of the above materials is not strong and not sustainable to a sudden falling-down. Besides, it is easily scraped and corroded; and is easily getting dirty and is hard to be cleaned. In addition, the shell can only change its shape and color, so that its appearance looks dummy and rough without beauty and sense of feel. 
         [0003]    Therefore, a prior art is invented, called “A parallel device skin with fiber lines”, comprising a mouse shell having an inlaying area; and a fiber knitting having a size fitting to the inlaying area to be in layed. The prior art improved in sustain ability to a falling-down and in appearance with sense of feel. Yet, the structure is still weak, easily scraped and corroded. Hence, the prior arts do not fulfill users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0004]    The main purpose of the present invention is to beautify appearance of parallel device accompanying a sense of feel with an enameled metal structure and thus to be prevented from scrape and corrosion with easy cleaning. 
         [0005]    To achieve the above purpose, the present invention is a skin having an enameled metal structure for parallel device, comprising a metal base layer; an image area on a surface of the metal base layer; and a coating layer made of a glass material and a metal oxide on the metal base layer and the image area, where the skin for parallel device further comprises a shell having a sunk are a on a surface of the shell to be deposed with the skin for parallel device. Accordingly, a novel skin having an enameled metal structure for parallel device is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0019]    The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention. 
         [0020]    Please refer to  FIG. 1  to  FIG. 5 , which are a perspective, an explosive and a sectional views showing a first preferred embodiment; and perspective views showing a second and a third preferred embodiments, according to the present invention. As shown in the figures, the present invention is a skin  1  having an enameled metal structure for parallel device, comprising a metal base layer  11 , an image area  12  and a coating layer  13 , where a parallel device obtains a beautiful appearance and a sense of feel with the skin; and the parallel device is thus prevented from scrape and corrosion and is easily cleaned. 
         [0021]    The metal base layer  11  is made of copper. 
         [0022]    The image area  12  is flat or is 3D (three-dimensional) hollowed-out; and is deposed on a surface of the metal base layer  11 . 
         [0023]    The coating layer  13  is deposed on the metal base layer  11  and the image area  12 ; and is made of a glass material and a metal oxide. The glass material is made by mixing with a borate or a silicate; and the glass material has more than 25 percents (% of boron oxide. 
         [0024]    When fabricating the skin  1 , the metal base layer  11  is formed into the shape of the skin  1  for parallel device, like a skin for a mouse. Then the image area  12  is hollowed out with a copper wire or a wire of other metal; and the image area  12  designed by the wire is burnt at 900 Celsius degrees (° C.) to be firmly welded on the metal base layer  11 . Then the glass material is filled into the hollowed-out image area  12  and is burnt at 750° C. to 800° C. to form a coating layer  13  above the metal base layer  11  and the image area  12 . In the end, a polish is done as required. Thus, a skin having an enameled metal structure for parallel device is obtained. Besides, the skin is not only for a mouse, but also for an external hard disk  1  a (as shown in  FIG. 4 ), a computer main frame  1   b  (as shown in  FIG. 5 ), a USB (universal serial bus) hub, a network device and a DVD (digital versatile disc) player. 
         [0025]    Please refer to  FIG. 6  to  FIG. 10 , which are a perspective, an explosive and a sectional views showing a fourth preferred embodiment; and perspective views showing the fifth and the sixth preferred embodiments. As shown in the figures, the skin  3  for parallel device further comprises a shell  2 . 
         [0026]    The shell  2  is made of plastics and has a sunk area  21  on a surface. 
         [0027]    The skin  3  for parallel device is put in the sunk area  21 . The skin  3  for parallel device comprises a metal base layer  31 ; an image area  32  on a surface of the metal base layer  31 ; and a coating layer  33  cove red on the metal base layer  31  and the image area  32 , where the image area  32  is flat or is 3D hollowed-out; and is deposed on a surface of the metal base layer  31 . The coating layer  33  is made of a glass material and a metal oxide; the glass material is made by mixing with a borate or a silicate; and the glass material has more than 25% of boron oxide. 
         [0028]    When fabricating, the shell  2  and the skin  3  for parallel device are separately made. On fabricating the shell  2 , the shell  2  is formed into a requested figure having a sunk area  21 . 
         [0029]    On fabricating the skin  3  for parallel device, the metal base layer  31  is formed into the shape of the sunk area  21 . The image area  32  is hollowed out with a copper wire or a wire of other metal; and the image area  32  designed by the wire is burnt at 900° C. to be firmly welded on the metal base layer  31 . Then the glass material is filled into the hollowed-out image area  32  and is burnt at 750° C. to 800° C. to form a coating layer  33  above the metal base layer  31  and the image area  32 . In the end, a polish is done as required 
         [0030]    After the shell  12  and the skin  3  for parallel device are separately fabricated, the skin  3  is adhered in the sunk area  21 . And the skin is not only for a mouse, but also for an external hard disk  2   a  (as shown in  FIG. 9 ), a computer main frame  2   b  (as shown in  FIG. 10 ), a USB (universal serial bus) hub, a network device and a DVD (digital versatile disc) player. 
         [0031]    Please refer to  FIG. 11  and  FIG. 12 , which are an explosive and a sectional views showing the seventh preferred embodiment. As shown in the figures, a sunk area  21  of a shell  2  has a concave  211  around on a border of the sunk area  21  to be locked with a convex  34  around on a border of a skin  3  for parallel device. Hence, the skin  3  for parallel device is locked in the sunk area  211  of the shell  2  by the concave  211  and the convex  34 . 
         [0032]    To sum up, the present invention is a skin having an enameled metal structure for parallel device, where a parallel device obtains a beautiful appearance and a sense of feel with the skin for parallel device; and the parallel device is thus prevented from scrape and corrosion and is easily cleaned.

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.
