Wire rack

Abstract

A wire rack includes: a pair of opposite supporting arms, each of which has opposite first and second ends; a connecting member interconnecting the supporting arms; a pair of opposite first confining arms extending respectively from the first ends of the supporting arms in opposite directions; a pair of pivot joints; and a pair of opposite second confining arms pivoted to the second ends of the supporting arms through the pivot joints, respectively, and rotatable relative to the supporting arms between a first angular position, in which each adjacent pair of the first and second confining arms cooperate with the respective one of the supporting arms to form into a U-shaped structure, and a second angular position, in which each of the second confining arms and the respective one of the supporting arms extend from the respective one of the pivot joints in opposite directions.

1 . A wire rack comprising:
 a pair of opposite supporting arms, each of which has opposite first and second ends;   a connecting member interconnecting said supporting arms;   a pair of opposite first confining arms extending respectively from said first ends of said supporting arms in opposite directions;   a pair of pivot joints; and   a pair of opposite second confining arms pivoted to said second ends of said supporting arms through said pivot joints, respectively, and rotatable relative to said supporting arms between a first angular position, in which each adjacent pair of said first and second confining arms cooperate with the respective one of said supporting arms to form into a U-shaped structure, and a second angular position, in which each of said second confining arms and the respective one of said supporting arms extend from the respective one of said pivot joints in opposite directions.   
   
   
       2 . The wire rack as claimed in  claim 1 , further comprising a stopping member mounted slidably on said supporting arms and including a crossbar that extends between said supporting arms and that has two opposite restraining ends, each of said second confining arms having a pivot end pivoted to said second end of the respective one of said supporting arms, said stopping member being slidable relative to said supporting arms between a restraining position, in which said crossbar is aligned with said pivot ends of said second confining arms and in which said restraining ends of said crossbar respectively confront said pivot ends of said second confining arms, thereby restraining said second confining arms from rotating from the first angular position to the second angular position, and a releasing position, in which said crossbar is offset from said pivot ends of said second confining arms, thereby permitting rotation of said second confining arms from the first angular position to the second angular position. 
   
   
       3 . The wire rack as claimed in  claim 2 , wherein each of said supporting arms is provided with a tubular part that is formed with a slot defined by a slot-defining wall, said slot-defining wall having opposite first and second ends, said stopping member further including a pair of inserts, each of which extends from said crossbar into said tubular part of a respective one of said supporting arms and each of which is formed with a resilient tongue protruding therefrom, engaging said second end of said slot-defining wall when said stopping member is disposed at the restraining position, and disengaging and spaced apart from said second end of said slot-defining wall when said stopping member is disposed at the releasing position. 
   
   
       4 . The wire rack as claimed in  claim 3 , wherein said pivot end of each of said second confining arms is formed with a retaining protrusion protruding therefrom and engaging an adjacent one of said restraining ends of said crossbar when said crossbar is disposed at the restraining position.
