Claim:
1. A combined portable step stool and workpiece support device, said device comprising: a folding frame having: a rigid front leg structure including a pair of spaced apart rigid front legs, each front leg having a lower portion and an upper portion, wherein said upper front leg portion is parallel to and offset from the lower portion and wherein a bridge portion is present between said lower and upper front leg portion, each front leg furthermore having a foot, and said rigid front leg structure including a first support bar interconnecting the front legs at an upper end thereof, said front legs and said first support bar each having a front side, and a rigid rear leg structure including a pair of spaced apart rigid rear legs, each rear leg having a foot, the rear leg structure being pivotally coupled to the front leg structure via first hinges for pivotable movement of the rear leg structure between an opened use position and a collapsed storage position, wherein said first hinges are connected to the bridge portions of the front leg structure, wherein the upper front leg portions and the first support bar form a first workpiece support bracket of the device, wherein the folding frame furthermore comprises steps consisting of an upper step and one lower step, said steps each being movably arranged for movement between a horizontal use position and a storage position, wherein said upper step is arranged at a distance below said bridge portions and wherein each step is adapted to support a person thereon, wherein the device furthermore comprises a pivotable rigid second workpiece support bracket, said second workpiece support bracket comprising a pair of spaced apart arms, each arm having a lower end pivotally connected via a second hinge to the bridge portion of a respective front leg, wherein each second hinge is integrated with the first hinges that is connected to the bridge portion of the respective front leg in a common hinge assembly having a common hinge axis, the second workpiece support bracket furthermore comprising a second support bar interconnecting said arms of the second workpiece support bracket at an upper end thereof, wherein, with the rear leg structure remaining in the opened use position, the rigid second workpiece support bracket is pivotal about said second hinges between a collapsed position, wherein the arms of the second workpiece support bracket lies in front of the upper front leg portions of the front legs and wherein the second support bar lies in front of the first support bar, and a use position, wherein the second workpiece support bracket is pivoted in a forward direction away from the front side of the first workpiece support bracket, wherein the first and second workpiece support brackets are in diverging arrangement when seen in side view of the device and wherein said device is open at the top, wherein in the use position of the second workpiece support bracket the first and second support brackets together define workpiece support faces in a horizontal support plane allowing to support a planar workpiece thereon, wherein in the use position of the second workpiece support bracket the open topped device allows to introduce from above a workpiece in between the first and second workpiece support brackets, wherein the front leg structure comprises a horizontal cross member between said front legs and wherein the rear leg structure comprises a horizontal cross member between said rear legs, and wherein the upper step is a pivotable step having a pivot axis near said horizontal cross member between said front legs, and wherein said upper step has a depth such that in said horizontal use position thereof and with the rear leg structure in opened use position thereof the upper step spans the distance between said horizontal cross members, wherein the lower step is composed of a front step part and a rear step part, the front step part being pivotally connected to the front leg structure and the rear step part being pivotally connected to the rear leg structure, the front and rear step parts also being pivotally connected to each other so as to allow said lower step to assume a folded state when the folding frame is collapsed, wherein a connecting assembly extends between the upper step and the lower step, such that pivoting the upper step away from said horizontal use position causes folding of the lower step resulting in collapsing of the folding frame; and wherein the feet of the front leg and the rear leg at each side of the device and side ends of the workpiece support brackets at said side of the device are in a common plane so as to allow to place the device with said side on a floor and use the feet and side ends of the workpiece support brackets at the other side of the device as support faces in a horizontal support plane for a workpiece.
