Automatic multiple-folding umbrella

Abstract

The present invention provides a ratio mechanism of an automatic multiple-folding umbrella, cooperating to cooperating to the opening mechanism, and main stick assembly and said handle control mechanism; wherein said terminal pulley of said ratio mechanism has a pulley for threading said inner stay wire over so that one end of said inner stay wire is fixed on said pulley assembly, and the another end is threaded through said pulley on said terminal pulley base, and the pulley of said pulley assembly, then passing through said terminal pulley base to be fixed on said locking head; said main stick is composed of four stick segments. Due to building up said switch, repeat press down said button can bring into being automatic opening and closing umbrella function.

I claim:  
     
         1 . A ratio mechanism of an automatic multiple-folding umbrella, cooperating to cooperating to the opening mechanism, comprised of upper and low strut nests and strut fids, and main stick assembly and said handle control mechanism; said ratio mechanism is comprised of an outer stay wire, an inner stay wire, a pulley assembly, a terminal pulley base, a locking head and a sleeve, wherein one end of said outer stay wire is fixed on one end of said pulley assembly, and the another end is fixed on said low strut nest of said opening mechanism; and said inner stay wire, said pulley assembly and said terminal pulley base are mounted into the hollow inside of said sleeve, therein said terminal pulley base is located on the bottom end of said sleeve; the feature of the present invention is that said terminal pulley of said ratio mechanism has a pulley for threading said inner stay wire over so that one end of said inner stay wire is fixed on said pulley assembly, and the another end is threaded through said pulley on said terminal pulley base, and the pulley of said pulley assembly, then passing through said terminal pulley base to be fixed on said locking head; said main stick is composed of four stick segments.  
     
     
         2 . A ratio mechanism of an automatic multiple-folding umbrella as claimed in  claim 1 , wherein said handle control mechanism is comprised of a handle base, a button component and a handle shell, wherein said handle base has a base hole at the center axially for holding said main stick in, a flange at the topside and an adjacent case at the bottom side of said flange for containing said button, a restoring strip and a lever hung on at the openings on the both open sides by a dowel pin separately, and a spring located on the bottom side of said restoring strip, and a slot for containing a cramp below next said restoring strip, said cramp connected with a spring with one end located on said handle base cooperating to a stopper, and touching against said lever with another end; said button assembly is comprised of a button and a switch connected together with a dowel pin, and a spring located between said button and said switch, wherein said switch has a central hollow space for containing a portion of said main stick and the low strut nest of said opening mechanism, said button covers on said restoring strip and said switch, and mounted at said case of said handle base; said low strut nest of said opening mechanism has a snap slot coordinating to said switch; said handle shell is a shell nesting over said handle base with a Ushape slot for holding said button.  
     
     
         3 . A ratio mechanism of an automatic multiple-folding umbrella as claimed in  claim 2 , wherein, said cramp is a flat frame with a lug extending inward at the inside.  
     
     
         4 . A ratio mechanism of an automatic multiple-folding umbrella as claimed in  claim 2 , wherein said switch has a tilt coordinating to said low strut nest of said opening mechanism.  
     
     
         5 . A ratio mechanism of an automatic multiple-folding umbrella as claimed in  claim 1 , wherein said low strut nest of said opening mechanism has a track-way at the outside wall holding on a restoring spring covered on top end by a sliding disk fastened with the outer end of said stay wire of said ratio mechanism.
