Waterproof cover assembly

Abstract

A waterproof cover assembly has a frame and a lid. The frame has a pivoting recess and two mounting notches. The mounting notches are formed respectively in ends of the pivoting recess. Each mounting notch has a polygonal pivoting hole, an opening and an extending slot. The opening and the extending slot are formed oppositely in the corresponding end of the pivoting recess and align to each other. The lid is connected pivotally to the frame and has a pintle with two polygonal positioning ends. The positioning ends are mounted rotatably in the pivoting holes of the mounting notches. When the lid is pivoted and the positioning ends and the pivoting holes are unmatched to each other, the openings and the extending slots are expanded to loose the pivoting holes. Therefore, the pivoting holes and the positioning ends are kept from being worn down to provide long-term positioning function.

1 . A waterproof cover assembly comprising:
 a frame having
 a top surface; 
 a bottom surface; 
 a pivoting side; 
 a mounting space being formed in the top surface; 
 a pivoting recess formed in the pivoting side through the top surface of the frame and having two ends; and 
 two mounting notches being formed respectively in the ends of the pivoting recess, and each mounting notch having
 a pivoting hole being polygonal and being formed in a corresponding end of the pivoting recess; 
 an opening being formed in the top surface of the frame, being formed in the corresponding end of the pivoting recess and communicating with the pivoting hole; and 
 an extending slot being formed in the corresponding end of the pivoting recess near the bottom surface of the frame, communicating with the pivoting hole and aligning with the opening; 
 
   a lid being connected pivotally to the frame and having
 a roof being mounted on and covering the top surface of the frame and having an annular edge; 
 a ring being formed transversely around the annular edge of the roof and having a bottom surface; and 
 a pintle being formed on the bottom surface of the ring, corresponding to and being mounted in the pivoting recess of the frame and having
 two positioning ends being polygonal and corresponding to and being respectively mounted rotatably in the pivoting holes of the mounting notches; 
 
   a bottom gasket being mounted on the bottom surface of the frame around the mounting space; and   a middle gasket being mounted between the top surface of the frame and the ring of the lid.

       7 . The waterproof cover assembly as claimed in  claim 1 , wherein the middle gasket is attached securely on the top surface of the frame. 
   
   
       8 . The waterproof cover assembly as claimed in  claim 2 , wherein the middle gasket is attached securely on the top surface of the frame. 
   
   
       9 . The waterproof cover assembly as claimed in  claim 3 , wherein the middle gasket is attached securely on the top surface of the frame. 
   
   
       10 . The waterproof cover assembly as claimed in  claim 1 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       11 . The waterproof cover assembly as claimed in  claim 2 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       12 . The waterproof cover assembly as claimed in  claim 3 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       13 . The waterproof cover assembly as claimed in  claim 4 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       14 . The waterproof cover assembly as claimed in  claim 5 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       15 . The waterproof cover assembly as claimed in  claim 6 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       16 . The waterproof cover assembly as claimed in  claim 7 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.   
   
   
       17 . The waterproof cover assembly as claimed in  claim 8 , wherein
 the frame has a holding recess being formed in the pivoting side through the top and bottom surfaces of the frame; and   the lid has a pawl being formed on the bottom surface of the ring and selectively engaging the holding recess of the frame.
