Device for converting adjustable snorkel into fixed snorkel

Abstract

An adjustable snorkel is convertible into a fixed snorkel by attaching a curved clamping device onto a flexible section of the adjustable snorkel and thereby setting the flexible section to selected curvature and working angle. The clamping device includes a curved body having an overall length corresponding to that of the flexible section of the snorkel, and two pairs of clamping noses provided at two ends of the curved body for clamping at two ends of the flexible section after the latter has been adjusted to the desired curvature and working angle. The flexible section having the clamping device attached thereto becomes rigid without producing any back pull and therefore allows the adjustable snorkel to function like a fixed snorkel. By detaching the clamping device from the flexible section, the adjustable snorkel is restored from the fixed snorkel.

What is claimed is;  
     
         1 . A device for converting adjustable snorkel into fixed snorkel, said adjustable snorkel including a flexible section that could be adjusted into desired curvature and working angle, said device comprising a curved body having an overall length corresponding to that of said flexible section of said adjustable snorkel, and two pairs of clamping noses provided at two ends of said curved body for clamping at two ends of said flexible section and thereby attaching said curved body onto said flexible section to set said flexible section to said desired curvature and working angle, allowing said adjustable snorkel to function like a fixed snorkel; and said device being removable from said flexible section to restore said adjustable snorkel at any time.  
     
     
         2 . The device as claimed in  claim 1 , wherein said curved body is a one-piece member.  
     
     
         3 . The device as claimed in  claim 1 , wherein said curved body includes serially connected head segment and connecting segments, each of said connecting segments being provided at a first end with two opposite through holes, and at a second end opposite to said first end with two opposite studs, said second end of each said connecting segment being fitted into said first end of a following connecting segment with said studs engaged into said through holes on said first end of said following connecting segment; and said head segment having an end being fitted into said first end of any said connecting segment with two studs provided at that end engaged into said through holes on said first end of said connecting segment.  
     
     
         4 . The device as claimed in  claim 1 , wherein said curved body includes serially connected head segment, intermediate segments, and tail segment; each of said intermediate segments being provided at a first end with two lugs and two through holes, and at a second end with two recesses and two studs adapted to engage with said two lugs and said two through holes, respectively, on said first end of a following intermediate segment; said head segment being provided only at a second end with said recesses and said through holes for engaging with said lugs and said studs, respectively, on said intermediate segment following said head segment, and said tail segment being provided only at a first end with said lugs and said studs for engaging with said recesses and said through holes, respectively, on said intermediate segment preceding said tail segment.  
     
     
         5 . The device as claimed in  claim 2 , wherein said curved body is connected to said flexible section of said adjustable snorkel by providing two engaging holes on one of said two pairs of clamping noses to engage with two studs correspondingly provided on one end of said flexible section of said adjustable snorkel, such that said device is attached to or detached from said flexible section through pivotally turning said curved body about said engaging holes and said studs to engage or disengage another said pair of clamping noses with or from said flexible section.  
     
     
         6 . The device as claimed in  claim 3 , wherein said curved body is connected to said flexible section of said adjustable snorkel by providing two engaging holes on one of said two pairs of clamping noses to engage with two studs correspondingly provided on one end of said flexible section of said adjustable snorkel, such that said device is attached to or detached from said flexible section through pivotally turning said curved body about said engaging holes and said studs to engage or disengage another said pair of clamping noses with or from said flexible section.  
     
     
         7 . The device as claimed in  claim 4 , wherein said curved body is connected to said flexible section of said adjustable snorkel by providing two engaging holes on one of said two pairs of clamping noses to engage with two studs correspondingly provided on one end of said flexible section of said adjustable snorkel, such that said device is attached to or detached from said flexible section through pivotally turning said curved body about said engaging holes and said studs to engage or disengage another said pair of clamping noses with or from said flexible section.
