ABSTRACT:
A generally horizontal base is provided and a pair of side-by-side elongated levers are pivotally supported at one pair of corresponding ends from the base for independent oscillation relative to the base between first positions generally paralleling the base and second positions angled relative to the base with the other ends of the levers inclined away from the base. Spring structure is connected between the levers and the base for yieldingly biasing the levers toward the second positions thereof, latch structure is provided and engageable with the levers to releasably retain the levers in the first positions thereof and a stand is provided for the base including a generally horizontal panel including opposite side marginal portions and a pair of wings pivotally supported from the marginal portions of the panel for swinging movement between collapsed positions generally paralleling and overlying the panel and extended limit positions with the wings disposed in upwardly projecting positions disposed at generally right angles relative to the panel. The free swinging edges of the wings are similarly inclined relative to the axes of oscillation of the wings and include first "Velcro" type fastening structure while the underside surfaces of the opposite marginal portions of the base include second "Velcro" type fastening structure. The first fastening structure is releasably engageable with the second fastener structure, whereby the base is removably supported from the stand in an inclined position.
