Abstract: A stage or other structure having support legs includes rollers which are mounted so as to be supporting the stage in a first position and having the stage legs support the stage in a second position. A lift mechanism includes actuating pedals near the ground for raising and lowering the assembly. A linkage pivots the roller mounting member between a raised and lowered position relative to a cross member on the frame. A second pedal is selectively engageable by a single foot for retaining the roller assembly in either the raised or lowered positions.

Abstract: A table is disclosed having extension leaves secured to opposite edges of the table top by hinges. The hinges include a first hinge member which is secured to the leaf and a second hinge member which is connected to the table top and is slidable relative to the table top. The first and second hinge members are pivotally connected to one another by a pivot pin carried by the slidable second hinge member and received within an elongated slot of the first hinge member. A rigid stop is secured to the second hinge member and spaced away from the pivot pin a distance less than a radius from the first end of the slot to the terminal end and a distance less than a radial distance from the second end of the slot to the terminal end.
