ABSTRACT:
A cross-member supporter for foldable furniture enables at least two construction members to selectively be supported in strongly extended cross structure or be folded in parallel compact structure for easy storage and carrying purposes. The cross-member supporter includes a supporter body having at least two vertical connecting holes and two inclined supporting holes provided therethrough. The two inclined supporting holes are inclined in opposite direction. The two inclined supporting holes are respectively extended from top to bottom through the two vertical connecting holes to form two supporting through slots. An axis of the vertical connecting hole of each of the supporting through slots is intersected with an axis of the respective inclined supporting hole, wherein each of the supporting through slots defines an upper supporting groove and a lower supporting groove which are inclined in opposite direction. The two elongated stems are penetrated through and pivotally connected at the two supporting through slots respectively. Thereby, each of the elongated stems can be inclinedly rested and supported by an upper groove surface and a lower groove surface of the respective inclined supporting hole so as to form a cross construction.
