Foldable furniture device

Abstract

A foldable furniture device includes a main frame, first and second leg frames connected pivotally to each other to move between a folded state and an unfolded state, a tubular sleeve connected pivotally to the main frame and sleeved slidably on the second leg frame, and a locking unit. The tubular sleeve includes a hollow protrusion projecting outwardly from an outer periphery of the tubular sleeve. The locking unit includes a hole formed in the second leg frame, and a locking member extending into the tubular sleeve to engage releasably the hole to lock the tubular sleeve against movement in the unfolded state.

1 . A foldable furniture device comprising: 
 a main frame;    first and second leg frames connected pivotally to each other to move between a folded state and an unfolded state, said first leg frame having a top end pivotally connected to said main frame;    a tubular sleeve connected pivotally to said main frame and sleeved slidably on said second leg frame, said tubular sleeve including a hollow protrusion projecting outwardly from an outer periphery of said tubular sleeve; and    a locking unit including a hole formed in said second leg frame, and a resilient locking member extending into said tubular sleeve to engage releasably said hole to lock said tubular sleeve against movement in said unfolded state.    
   
   
       2 . The foldable furniture device as claimed in  claim 1 , wherein said resilient locking member includes a forward portion extending into said tubular sleeve, and a rear portion extending outwardly from said hollow protrusion and being operable to release said forward portion from engaging said hole to permit movement of said tubular sleeve in said folded state.  
   
   
       3 . The foldable furniture device as claimed in  claim 1 , further comprising a pull member connected to said rear portion of said locking member.
