Adjusting sleeve assembly for a sunshade with a tiltable canopy

Abstract

An adjusting sleeve assembly includes an adjusting sleeve slidably mounted around an upright support member of a sunshade and a mounting member extending outward from the adjusting sleeve and including a U-shape path therein. A pivotal block is pivotally mounted in the mounting member. A connecting rod includes a first end connected to the pivotal block to pivot therewith and a second end pivotally connected to an arcuate tube for supporting a canopy of the sunshade. A push member is slidably received in the pivotal block and includes an end for manual operation. A positioning peg includes a first end securely attached to the push member to move therewith and a second end that is urged into one of two positioning ends of the U-shape path for retaining the connecting rod in place with respect to the mounting member.

What is claimed is:  
     
         1 . A sunshade comprising: 
 an upright support member having an upper end, a holding sleeve being pivotally mounted to the upper end of the upright support member;    an arcuate tube supported by and slidable relative to the holding sleeve and having a first end and a second end;    a canopy attached to the first end of the arcuate tube; and    an adjusting sleeve assembly comprising: 
 an adjusting sleeve slidably mounted around the upright support member;  
 a lever for releasably retaining the adjusting sleeve in place with respect to the upright support member;  
 a mounting member extending outward from the adjusting sleeve and including a slot in a distal end of the mounting member and defining a U-shape path in the mounting member, the U-shape path including two positioning ends and a passage communicating with the positioning ends;  
 a pivotal block pivotally mounted in the mounting member and extending along a direction transverse to an extending direction of the mounting member, the pivotal block including a longitudinal chamber and a slot defined in an outer periphery of the pivotal block and communicated with the longitudinal chamber;  
 a connecting rod including a first end connected to the pivotal block to pivot therewith and a second end pivotally connected to the second end of the arcuate tube;  
 a push member slidably received in the longitudinal chamber of the pivotal block and including an end for manual operation, a positioning peg including a first end securely attached to the push member to move therewith and a second end extending through the slot of the pivotal block and into one of the positioning ends of the U-shape path;  
   wherein when the second end of the push member is retained in one of the two positioning ends, the connecting rod is retained in place with respect to the mounting member; and    wherein the second end of the push member is moved out of one of the positioning ends into the passage when the push member is pushed, and the connecting rod together with the pivotal block are pivotable relative to the mounting member to a position where the second end of the push member is urged to be engaged with the other one of the positioning ends.    
     
     
         2 . The sunshade as claimed in  claim 1 , wherein the pivotal block includes a groove in the outer periphery thereof, the pivotal block further including a longitudinal through-hole communicated with the groove, the first end of the connecting rod including a hole, and a positioning pin being extended through the longitudinal through-hole of the pivotal block and the hole of the connecting rod, thereby securely connecting the first end of the connecting rod to the pivotal block to pivot therewith.  
     
     
         3 . The sunshade as claimed in  claim 1 , wherein the push member includes a first end and a second end, a push button being securely attached to the second end of the push member, an elastic element having a first end attached to the first end of the push member and a second end attached to an inner end wall defining the longitudinal chamber of the pivotal block.  
     
     
         4 . The sunshade as claimed in  claim 3 , wherein the push member includes a mediate portion with a transverse receptacle, the first end of the positioning peg being securely attached to the push member to move therewith.  
     
     
         5 . The sunshade as claimed in  claim 1 , wherein the upright support member includes a lower support tube and an upper support tube that has a lower end telescopically received in the lower support tube, the holding sleeve being pivotally mounted to an upper end of the upper support tube, and further including a control sleeve for controlling telescopic movement of the upper support tube relative to the lower support tube.  
     
     
         7 . The sunshade as claimed in claim  6 , wherein the arcuate tube includes an outer tube section and an inner tube section that has an end telescopically received in the outer tube section, the canopy being attached to another end of the inner tube section, the second end of the connecting rod being pivotally connected to the outer tube section, and further including a further control sleeve for controlling telescopic movement of the inner tube section relative to the outer tube section.  
     
     
         8 . The sunshade as claimed in  claim 7 , wherein the pivotal block includes a groove in the outer periphery thereof, the pivotal block further including a longitudinal through-hole communicated with the groove, the first end of the connecting rod including a hole, and a positioning pin being extended through the longitudinal through-hole of the pivotal block and the hole of the connecting rod, thereby securely connecting the first end of the connecting rod to the pivotal block to pivot therewith.  
     
     
         9 . The sunshade as claimed in  claim 7 , wherein the push member includes a first end and a second end, a push button being securely attached to the second end of the push member, an elastic element having a first end attached to the first end of the push member and a second end attached to an inner end wall defining the longitudinal chamber of the pivotal block.  
     
     
         10 . The sunshade as claimed in  claim 9 , wherein the push member includes a mediate portion with a transverse receptacle, the first end of the positioning peg being securely attached to the push member to move therewith.
