Sealing strap

Abstract

A sealing strap includes a first strap body including a first base portion, a first lining, a second lining, a first interlocking series of teeth extended from the first lining and a male engaging member with a male engagement portion extended from the second lining, a second strap body including a second base portion, a third lining, a fourth lining, a second interlocking series of teeth extended from the third lining, and a female engaging member with a female engagement portion extended from the fourth lining, and a zipper slider movable to force the first interlocking series of teeth into engagement with the second interlocking series of teeth and the male engagement portion of the male engaging member into engagement with the female engagement portion of the female engaging member to achieve excellent tensile strength and waterproof effects.

What the invention claimed is: 
     
         1 . A sealing strap, comprising:
 a first strap body comprising a first base portion, a first lining and a second lining respectively longitudinally extending along one lateral side of said first base portion at different elevations, a first interlocking series of teeth longitudinally extending along one lateral side of said first lining opposite to said first base portion, and a male engaging member longitudinally extending along one lateral side of said second lining opposite to said first base portion, said male engaging member comprising a male engagement portion longitudinally extending along one lateral side of said second lining opposite to said first base portion;   a second strap body comprising a second base portion, a third lining and a fourth lining respectively longitudinally extending along one lateral side of said second base portion at different elevations, a second interlocking series of teeth longitudinally extending along one lateral side of said third lining opposite to said second base portion and interlockable with said first interlocking series of teeth, and a female engaging member longitudinally extending along one lateral side of said fourth lining opposite to said second base portion, said female engaging member comprising a female engagement portion longitudinally extending along one lateral side of said fourth lining opposite to said second base portion and adapted for engaging said male engagement portion of said male engaging member; and   a zipper slider coupled to said first strap body and said second strap body for moving said first interlocking series of teeth into engagement with said second interlocking series of teeth and said male engagement portion of said male engaging member into engagement with said female engagement portion of said female engaging member, said zipper slider comprising two first chain grooves bilaterally disposed in a front bottom side thereof for receiving said first interlocking series of teeth and said second interlocking series of teeth, a first spacer wall disposed between said first chain grooves, a first coupling chamber defined in a rear bottom side thereof in communication with said two first chain grooves, two second chain grooves bilaterally disposed in a front top side thereof above said first chain grooves for receiving said male engaging member and said female engaging member, a second spacer wall disposed between said two second chain grooves, and a second coupling chamber defined in a rear top side thereof in communication with said two second chain grooves above said first coupling chamber.   
     
     
         2 . The sealing strap as claimed in  claim 1 , wherein said male engaging member comprises two first vertical bearing walls respectively abutted to opposing top and bottom walls of said second lining at right angles; said female engaging member comprises two second vertical bearing walls respectively abutted to opposing top and bottom walls of said fourth lining at right angles; said zipper slider further comprises two pairs of first stop ribs respectively disposed in opposing top and bottom sides at two opposite lateral sides of said first coupling chamber, and two pairs of second stop ribs respectively disposed in opposing top and bottom sides at two opposite lateral sides of said second coupling chamber. 
     
     
         3 . The sealing strap as claimed in  claim 1 , wheein said zipper slider further comprises crown located at a top side thereof, and a pull tab coupled to said crown.
