Patent number: 8602378Abstract: A collapsible folding stand for use with a portable table saw that is attached to the stand. In a closed position, the stand is generally vertically oriented with the object attached to a top frame. To open the stand a locking mechanism is released which enables a folding mechanism supporting the top frame to unfold in a manner whereby the rear legs having wheels that separate from forward side struts which contact the ground, with the center of gravity of the object being positioned between the wheels and the front ground contact points so that the weight of the object tends to separate the same and bring the top frame into a generally horizontal position. To move the rolling stand to its closed position, the user needs only to lift the handle and the top frame will then move to its generally vertical closed position.Type: GrantFiled: November 20, 2012Date of Patent: December 10, 2013Assignee: Robert Bosch GmbHInventors: Ramon Tam, Brian Taylor
