Swing having foldable leg unit

Abstract

A swing includes a swing frame and a swing chair assembly. The swing frame includes left and right leg units, and a top horizontal bar connected between the left and right leg units. Each of the left and right leg units includes a front leg member having a top end connected to the top horizontal bar, and a rear leg member having a top end connected pivotally to the front leg member below the top horizontal bar. The front and rear leg members respectively have bottom ends which are movable toward or away from each other to place the left and/or right leg units in a folded position or an unfolded position. The swing chair assembly is hung movably on the top horizontal bar.

1 . A swing comprising: 
 a swing frame including left and right leg units, and a top horizontal bar connected between said left and right leg units, each of said left and right leg units including a front leg member having a top end connected to said top horizontal bar, and a rear leg member having a top end connected pivotally to said front leg member below said top horizontal bar, said front and rear leg members respectively having bottom ends which are movable toward or away from each other to place said left and/or right leg units in a folded position or an unfolded position; and    a swing chair assembly hung movably on said top horizontal bar.    
   
   
       2 . The swing as claimed in  claim 1 , wherein said front leg member includes a link member that has a top end fixed rigidly to said front leg member below said top horizontal bar and that is inclined rearwardly and downwardly with respect to said front leg member, said link member further having a bottom end extending away from said front leg member, said top end of said rear leg member being connected pivotally to said link member between said top and bottom ends of said link member.  
   
   
       3 . The swing as claimed in  claim 2 , wherein said link member has a U-shaped cross section, and embraces partially said top end of said rear leg member, said link member including a rear closed end to abut against said top end of said rear leg member when said rear leg member moves away from said front leg member, a rear cutout formed above said rear closed end, and a front open end that extends from said top to bottom ends of said link member to permit said rear leg member to pivot toward said front leg member, said rear closed end extending upwardly from said bottom end of said link member, said rear cutout extending from said rear closed end to said top end of said link member.  
   
   
       4 . The swing as claimed in  claim 1 , wherein said swing frame further includes a reinforcing bar disposed between said front and rear leg members, said reinforcing bar having a front end pivoted to said front leg member near said bottom end of said front leg member, and a rear end pivoted to said rear leg member, said rear end of said reinforcing bar being higher than said front end.  
   
   
       5 . The swing as claimed in  claim 4 , wherein said front leg member further has a front strap that projects rearwardly, said rear leg member further having a rear strap projecting forwardly, said front and rear ends of said reinforcing bar being respectively pivoted to said front and rear straps.  
   
   
       6 . The swing as claimed in  claim 4 , wherein said reinforcing bar is telescopic.  
   
   
       7 . The swing as claimed in  claim 6 , wherein said reinforcing bar includes an outer tube having a locking hole, an inner rod inserted telescopically into said outer tube, and a resilient retaining unit extendable out of said inner rod to engage said locking hole.  
   
   
       8 . The swing as claimed in  claim 1 , wherein said swing frame further includes a horizontal cross bar connected between said rear leg members of said left and right leg units below said rear straps of said rear leg members.  
   
   
       9 . The swing as claimed in  claim 8 , wherein said rear leg members have positioning pieces below said rear straps of said rear leg members, said horizontal cross bar having two insert portions provided respectively on two opposite ends thereof and engaged respectively to said positioning pieces.  
   
   
       10 . The swing as claimed in  claim 1 , wherein said front and rear leg members are curved.
