Folding structure for chairs

Abstract

A folding structure for chairs includes a front foot support, a rear foot support, a seat frame, an armrest, and a back frame pivotally engaged with the seat frame and being extensible and foldable against each other. The front foot support has a top end pivotally engaged with the armrest at an inner side of a middle section thereof. The top end has an outer side pivotally engaged through the same axis with the rear foot support. The front foot support has a middle section pivotally engaged with a middle section of the seat frame. The rear foot support has a middle section pivotally engaged with the back frame through a pivot fastener. The armrest has a rear end pivotally engaged with the back frame. Thus the front foot support may be moved toward the rear foot support and folded in a juxtaposed manner to contact the bottom side of the armrest, and the back frame and seat frame may be folded and stacked for the chair to form a minimum thickness to facilitate carrying and storing, and also to save storage space .

I claim:  
     
         1 . A folding structure for a chair, comprising: 
 a front foot support, a rear foot support, a seat frame, an armrest, and a back frame pivotally engaged with the seat frame and being extensible and foldable against each other;    wherein the front foot support has a top end pivotally engaged with the armrest at an inner side of a middle section thereof, the top end having an outer side pivotally engaged through the same axis with the rear foot support, the front foot support having a middle section pivotally engaged with a middle section of the seat frame, the rear foot support having a middle section pivotally engaged with the back frame through a pivot fastener, the armrest having a rear end pivotally engaged with the back frame, thereby the front foot support being foldable toward the rear foot support in a juxtaposed manner to contact the bottom side of the armrest, and the back frame and the seat frame being foldable and stacked for the chair to have a small thickness and space.
