Abstract
A height-adjustable frame for furniture, such as a worktable or desk, is disclosed. The frame includes first and second height-adjustable leg elements pivotable about first and second pivot axes between folded-out and folded-in positions. A rotatable shaft is arranged between the first and second leg elements to synchronously drive first and second height adjustment arrangements. The shaft includes a middle section and first and second end sections pivotable towards the middle section about respective first and second joint axes. A locking structure is included that locks the first and second leg elements in a folded-out position, when the first and second joint axes do not run approximately parallel to the first and second pivot axes, and that unlocks when the first and second joint axes run approximately parallel to the first and second pivot axes to permit the first and second leg elements to pivot into a folded-in position.
