Abstract:
The present invention relates to a type of fastener for securing computer case side covers which no longer uses screws or bolts to secure the computer case side covers but attaches these side covers through clamp fasteners onto the computer case.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1) Field of The Invention  
         [0002]     The present invention relates to a new type of fastener for computer case side covers, more specifically a fastener which secures the computer case side covers through use of a clamp mechanism. Said clamp mechanism enables the computer case side covers to be attached fast and convenient to the computer case.  
         [0003]     2) Description of The Prior Art  
         [0004]     The present invention relates to a new type of fastener for the computer case side covers which no longer uses screws or bolts to secure the computer case side covers but attaches these side covers through clamp fasteners onto the computer case.  
         [0005]     Referring to  FIG. 1  on this picture you see a traditional computer case  10 , with a computer case frame  100  attached to a front panel  200 , a top cover  300  and two side covers  400  to encase the inner parts of the computer and thus forming the complete computer case  10 . Both side covers  400  are secured by using screws A to attach the side covers  400  through the screw holes  401  to the screw holes  101  on the computer case frame  100 . Such a structure still has a number of weaknesses: 
        1. Too much manual force needed to attach the side cover.     2. It&#39;s time-wasting to attach the side cover.     3. Tools like a screw driver are needed.     4. In mass production, the cases can not be assembled fast enough.     5. It&#39;s time-consuming and laborious during maintenance.        
 
       SUMMARY OF THE INVENTION  
       [0011]     The objective of the present invention is to provide a new fastener for computer case side covers, which can attach both side covers through a fast and convenient clamp fastening mechanism, thus reducing the time and labor needed for assembly or maintenance, thus further improving the commercial value of the present structure.  
         [0012]     To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0019]     Referring to  FIG. 2  to  FIG. 3 , the present invention comprises a computer case  1 , having a computer case frame  11 , attached to a front panel  12 , a top cover  13  and two side covers  14 , further including the following attributes:  
         [0020]     Both side covers  14  make use of one upper and one lower clamp  2  to attach the side covers  14  to the computer case frame  11 . The computer case frame  11  has a guiding hole  111 . Next to the guiding hole  111  there is a horizontal guiding slit  1111  and a sideways bracing  1112 . Two bracing holes  112  each formed respectively above and below the guiding slit  1111 .  
         [0021]     Referring to  FIG. 4 , the clamp  2  comprises a clamp socket  21  and a clamping piece  22 . The rear end of the clamp piece  22  fits into a central slit  211  on the clamp socket  21 . The upper and lower end of the clamp socket  21  comprises a rounded axis socket  212 . The rounded axes  221  disposed on the upper and lower sides at the rear end of the clamping piece  22  fit into the axis socket  212 , thus securing the position of the clamping piece  22  on the clamp socket  21 . A pushing piece  222  having a pressure piece  2221  is disposed at the other end of the clamping piece  22 . The pushing piece  222  fits into the guiding hole  111  of the computer case frame  11 , thus securing its position in the guiding slit  1111 . On the front end of the clamp socket  21  there is an upper and a lower fastening hook  213 . These fastening hooks  213  fit into the bracing holes  112  on the computer case frame  11 . On the back side of the clamp socket  21  there is a backward hook  214 , which fits into the sideways bracing  1112  of the computer case frame  11 .  
         [0022]     Referring to  FIG. 5 , the side covers  14  have to be mounted onto the computer case frame  11 . First, a C-shaped hole  1411  at a bend edge  141  of the side cover  14  has shown no connection yet to the clamp  2 , such that both side covers  14  mounted onto the computer case frame  11  is accordingly shown without fastening the clamps  2 . Then, as shown in  FIG. 6 , when the user pushes the pushing piece  222  of the clamping piece  22 , thus forcing the clamping piece  22  to pivotally turn with the axis socket  212 . This results in the clamping piece  22  being pushed into the C-shaped hole  1411  at the bend edge  141  of the side cover  14 . The pressure piece  2221  on the other end of the pushing piece  222  will exert pressure to the bend edge  141  of the side cover  14 , thereby securing the side cover  14  fast and easy.  
         [0023]     As the above description shows, the present invention relates to a clamp fastener, which enables the user to fasten the two side covers fast and easily to the computer case frame, thus reducing the time and labor needed for assembly or maintenance, further improving the commercial value of the present structure.  
         [0024]     It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
