Chair assembly with a tilt-adjustable canopy

Abstract

A chair assembly includes a pair of upright side frames, a seat member disposed between the side frames, a canopy frame with an intermediate portion mounted pivotally on the side frames, and a telescopic linking rod with an upper end pivoted to a rear end portion of the canopy frame, and a lower end pivoted to one of the side frames. The linking rod is operable for adjusting its length, and is operable for retention at an adjusted length so as to permit tilt-adjustment of the canopy frame.

I claim:  
     
         1 . A chair assembly comprising: 
 a support unit including a pair of upright side frames which are spaced-apart in a horizontal first direction, each of said side frames having a lower end portion adapted to be supported on a ground surface, and an upper end portion;    a seat member disposed between and mounted on said side frames;    a canopy frame disposed above said seat member, said canopy frame having front and rear end portions, and an intermediate portion extending between said front and rear end portions and mounted pivotally on said upper end portions of said side frames so as to be pivotable about a horizontal pivot axis parallel to the first direction; and    a telescopic linking rod having an upper end connected pivotally to one of said front and rear end portions of said canopy frame, and a lower end connected pivotally to one of said side frames of said support unit at a point below said upper end portion of said one of said side frames, said linking rod being operable for adjusting length thereof and being operable for retention at an adjusted length so as to permit tilt-adjustment of said canopy frame.    
     
     
         2 . The chair assembly as claimed in  claim 1 , wherein said upper end portion of each of said side frames is formed with a tubular sleeve which extends in said first direction and which has opposite open ends, said support unit further including a horizontal bar having opposite end portions extending axially and respectively into said tubular sleeves, said canopy frame having a looped rectangular frame member which includes front and rear rod sections parallel to said horizontal bar, and a pair of lateral rod sections transverse to said horizontal bar and interconnecting said front and rear rod sections, said horizontal bar and said tubular sleeves being disposed within said looped rectangular frame member, each of said lateral rods sections having a front end portion connected to said front rod section, a rear end portion connected to said rear rod section, and an intermediate portion mounted pivotally on a respective said opposite end portions of said horizontal bar so as to be pivotable about an axis of said horizontal bar.  
     
     
         3 . The chair assembly as claimed in  claim 2 , further comprising a pair of pivot axles, each of which extends transversely through said intermediate portion of a respective one of said lateral rod sections and extends axially into a respective one of said tubular sleeves, each of said pivot axles having a threaded end portion which engages threadedly a respective one of said opposite end portions of said horizontal bar.
