Umbrella supporting mount

Abstract

An umbrella supporting mount can be easily and quickly secured to a flat surface of a table or roof of a vehicle in a stable and firm manner without shaking at all. The supporting mount has an integrally punched metal lid of proper height and is equipped with a plurality of vent holes and a pair of symmetric mounting holes on the vertical periphery thereof so as to permit a cranked driving control shaft having a handle at one end to be located in a hollow interior of the lid. A driven unit integrally made of hard plastics consists of a circular base board and a vertically extended block having a driving hole disposed at the center thereof. The circular base board of the driven unit is partially wrapped around by a sucking attachment which is made of flexible rubber and has a peripheral skirt defined at the bottom edge thereof. So, a cranked section of the cranked driving control shaft can be engaged with the driving hole of the driven unit and the activation of the driving control shaft results in the lift up of the driven unit to force air in the skirted area of the sucking attachment out of the lid via the vent holes so as to produce a vacuum effect for firmly fix the supporting mount to a flat surface.

I claim:  
     
         1 . An umbrella supporting mount comprising a lid, a driven unit, a sucking attachment, a driving control shaft, a tubular sleeve and two end caps, wherein: 
 said tubular sleeve is made of elastic rubber; and    said two end caps each having an engagement opening at one end are respectively a short cylinder;    said lid is a metallic piece integrally punched into a cover in a circular shape with of a proper height having two symmetric round mounting holes on the opposite positions of a circular periphery thereof; a plurality of vent holes are disposed between said round mounting holes; and said lid has a hollow interior;    a housing tube used for holding an umbrella being engaged with said lid;    said driven unit is integrally made and has a circular base board at the bottom thereof and has a vertically projected block at the center hereof; at the center of said block is disposed an axially extended driving hole which has a flat bottom base and a symmetric arc shaped side wall extending to a summit of the driving hole;    said sucking attachment, a circular element made of elastic rubber, has a top and bottom section; the former has an engagement cavity with a stepwise projection disposed at the center for partially wrapping up said circular base board of said driven unit; a periphery of said bottom section is provided with a supporting skirt having a larger diameter than that of said top section and a sloped inward peripheral plane; said sloped plane has a large recessed area at the center of said bottom section;    said driving control shaft is integrally formed having a thin and elongated driving stick at both ends and a cranked middle section; an actuation handle extends vertically from one end of said driving stick;    
     
     
         2 . The umbrella supporting mount as claimed in  claim 1  wherein said vent holes of said lid are made in different shape.  
     
     
         3 . The umbrella supporting mount as claimed in  claim 1  wherein said lid is made of metal.  
     
     
         4 . The umbrella supporting mount as claimed in  claim 1  wherein said driven unit is made of hard plastics.  
     
     
         5 . The umbrella supporting mount as claimed in  claim 1  wherein said driving hole of said driven unit has a smooth arc surface at the summit thereof for driving engagement with said cranked middle section of said driving control shaft.  
     
     
         6 . The umbrella supporting mount as claimed in  claim 1  wherein said cranked middle section is made in a smooth arc shape in engagement with said smooth arc surface of said driving hole.
