摘要:
A collapsible music stand including a ground engaging base portion, an upright portion, and a selectively collapsible desk portion. The desk has a pair of body portions operably coupled by a pair of over-center toggle linkages. Each over-center toggle linkage is selectively positionable in at least a first favored position, wherein the linkage is extended so that the body portions are spaced apart and the linkage opposes movement of the body portions toward each other. Further, the toggle linkages are positionable in a second favored position wherein the body portions are freely movable toward each other to collapse the desk. The desk further includes at least one resilient element arranged so as to bias the body portions toward each other when each the toggle linkages are positioned in the first favored position.
