Upper cover of a garbage can

Abstract

An upper cover of a garbage can includes a fitting frame, an upper cover body, an outer frame and two combining members. The combining members are respectively composed of a pivotal cylinder and a torsion spring, combined with the pivotal members of the upper cover body and the inner frame, letting the upper cover body to swing slowly up to an open upright condition or swing down to a closed condition with the pivotal members as pivots and by means of the torsion springs immersed in friction oil and turned in an untwisted natural condition or in a twisted condition. The upper cover body is pivotally combined with the inner side of the fitting frame combined with an outer frame, which is then assembled on the upper edge of a garbage can, letting the upper cover swung down or up to close or open slowly without noise by pressing.

1 . An upper cover of a garbage can comprising: 
 a fitting frame formed with an opening in the center portion, said fitting frame having two pivotal grooves respectively bored in the opposite sides of a rear portion, a stop stud fixed in front of each said pivotal groove;    an upper cover body having two pivotal members respectively provided at the opposite sides of a rear portion;    two combining members respectively and pivotally fitted in both said pivotal groove of said fitting frame and said pivotal member of said upper cover body, each said combining member consisting of a pivotal cylinder and a torsion spring;    an outer frame having its inner side fitted with said fitting frame; and    said pivotal cylinder and said torsion spring of said combining member together received in both said pivotal groove of said fitting frame and said pivotal member of said upper cover body to combine said upper cover body in an open upright position with said fitting frame, thus finishing assembling work of said upper cover with a garbage can, said upper cover body in the open upright position possible to be swung down to close on said fitting frame or to be swung up to open to the open upright position.    
   
   
       2 . The upper cover of a garbage can as claimed in  claim 1 , wherein said fitting frame has its outer peripheral edge provided with plural engage members to engage with the upper projecting edge of a garbage can.  
   
   
       3 . The upper cover of a garbage can as claimed in  claim 1 , wherein each said pivotal member of said upper cover body is fixed therein with a secure rod for an inner end of said torsion spring to be secure thereon.  
   
   
       4 . The upper cover of a garbage can as claimed in  claim 1 , wherein said pivotal cylinder of said combining member is provided with a pivotal member and a secure rod, said secure rod fixed in the interior of said pivotal member for an outer end of said torsion spring to be secured thereon.
