Patent number: 9533410Abstract: A foldable stand includes two stand legs pivotally connected together. A positioning unit is set between the two stand legs and includes a first link pivotally connected to a second link, a locating plate mounted in the first link and a locking pin mounted in the second link. The foldable stand also includes a control unit having a first pedal mounted at the second link and pressable to move the first and second links toward each other into a folded position. In the folded position, the locking pin is forced into engagement with the locating plate. A second pedal is pivotally connected to the second link and pressable to pull the locking pin out of the locating plate for enabling the two stand legs to be biased from the folded position to an extended position.Type: GrantFiled: December 15, 2015Date of Patent: January 3, 2017Assignee: REXON INDUSTRIAL CORP., LTD.Inventors: Wen Chin Chiang, Chun Che Chen
