Abstract: A control structure of a supporting foot for collapsible furniture comprises a base having a rotation shaft fixed on the supporting foot. A concave hole is formed in the base and an extension shaft of the rotation shaft is combined with a spring and a sleeve. When the supporting feet are rotated to a predetermined position where the sleeve aims exactly at the concave hole of the base, the sleeve is pushed into the hole by the spring to fix and unfold the supporting feet. On the contrary, when the sleeve is pulled out of the hole, the supporting feet are free now for getting folded and closed together with the furniture body by relative rotation.

Abstract: An image forming film includes a substrate having a non-light-absorbing surface. At least two light-transmitting layers each comprising a pattern, are stacked over each other and formed on the non-light-absorbing surface. A light-transmitting surface sheet is attached to the stack of the layers. The surface sheet has an outer surface on which a plurality of raised, substantially parallel strips are formed, each strip having a side face for directing light from the patterns of the layers toward different angles.
