Beverage holder with plunger mechanism

Abstract

A beverage holder that can be attached to a surface and repositioned. The holder has a c-shaped clamp portion. The lower jaw portion of the clamp has an aperture receiving a plunger member. The plunger member has a proximal end enlarged head portion. A compressible spring is positioned around the plunger member. A flange is attached to the distal end of the plunger member. A non-slip pad is attached to the upper surface of the flange and the upper jaw portion of the c-shaped clamp. A base portion and circumferential ring are attached to the vertical portion of the c-shaped clamp. A cup or beverage container can be accommodated by the base and circumferential ring. In use the plunger is retracted compressing the spring and allowing attachment beverage holder to a surface.

1 . A beverage holder comprising: 
 a c-shaped clamp with a generally horizontal upper portion including a first jaw portion, a generally vertical portion and a second generally horizontal portion, said second generally horizontal portion, including a second jaw portion having a aperture of predetermined diameter, said c-shaped clamp aligned along a generally vertical axis;    a plunger member received by said opening, said plunger member having a proximal end portion, and a distal end, said proximal end having a head with a diameter greater than said aperture;    a spring positioned around said plunger member with a diameter greater than said aperture;    a flange attached at said distal end of said plunger member, said flange having and upper and lower surface, said lower flange surface in frictional contact with said spring;    a first anti-slip pad attached to said first jaw portion of said upper portion of said c-shaped clamp;    a second anti-slip pad attached to said upper surface of said flange;    a base portion attached to said vertical portion of said clamp portion;    at least one circumferential ring portion attached to said vertical portion of said c-shaped clamp, said circumferential ring being substantially parallel to said base portion, a predetermined spacing from said base portion;    
   
   
       2 . A beverage holder according to  claim 1  where said at least one circumferential ring has a slot.  
   
   
       3 . A beverage holder according to  claim 1  where said scratch anti-slip pad is made of group of rubber or plastic.  
   
   
       4 . A beverage holder according to  claim 1  further comprising a shortening means disposed between said flange and said spring.  
   
   
       5 . A beverage holder comprising: 
 a c-shaped clamp portion with a generally horizontal upper portion including a first jaw portion, a generally vertical portion and a second generally horizontal portion, said second generally horizontal portion, including a second jaw portion having a aperture of predetermined diameter, said c-shaped clamp aligned along a generally vertical axis;    a plunger member received by said opening, said plunger member having a proximal end portion, and a distal end, said proximal end having a head with a diameter greater than said aperture;    a spring positioned around said plunger member with a diameter greater than said aperture;    a flange attached at said distal end of said plunger member, said flange having and upper and lower surface, said lower flange surface in frictional contact with said spring;    a first anti-slip pad attached to said first jaw portion of said upper portion of said c-shaped clamp;    a second anti-slip pad attached to said upper surface of said flange;    a base portion attached to said vertical portion of said clamp portion; and    at least 2 circumferential rings attached to said vertical portion of said c-shaped clamp portion, said circumferential rings are substantially parallel and having a predetermined spacing.    
   
   
       6 . A beverage holder according to  claim 5  further comprising a shortening means disposed between said flange and said spring.
