Sunshade frame

Abstract

A sunshade frame has an upper support member secured to a top end of a shank; the ribs of the frame are each pivoted to a corresponding one of longitudinal trenches of the upper support member from an inner end. The frame has a lower support member movably connected to the shank, and spreader rods pivoted to the lower support member from inner ends; the spreader rods are each pivoted to a corresponding one of the ribs by means of a pivotal pin from an outer end with an elastic member disposed in between to prevent the connection from getting loose in case the pivotal pin is too long for the width of same. The upper, and the lower support members have an upper, and a lower confining rim respectively to prevent the ribs and the spreader rods from pivoting beyond same to a wrong position.

What is claimed is:  
     
         1 . A sunshade frame, comprising 
 an upper support member secured to an upper end of a shank; said upper support member having a plurality of longitudinal receiving trenches spaced apart on an outer side each receiving a corresponding one of inner ends of ribs pivoted to a locating member secured to a transverse trench intersecting with said longitudinal receiving trenches; a plurality of spreader rods; said spreader rods being each pivoted to a corresponding one of longitudinal receiving trenches of a lower support member movably connected to said shank from inner ends of said spreader rods; said spreader rods being each pivoted to a corresponding one of said ribs from an outer end; and characterized by a confining rim on upper ends of said longitudinal trenches of said upper support member, said confining rim being capable of preventing said ribs from pivoting up beyond same.    
     
     
         2 . The sunshade frame as claimed in  claim 1 , wherein said lower support member has a confining rim on lower ends of said longitudinal receiving trenches thereof, preventing said spreader rods from pivoting down beyond same.  
     
     
         3 . The sunshade frame as claimed in  claim 1 , wherein said spreader rods being each pivoted to said corresponding rib by means of a pivotal pin with an elastic member being disposed between said spreader rod and said rib.
