Interretractable Folding Piano Stand

摘要

An interretractable folding stand includes outer, inner, and top pairs of mirror-image members. Each outer member is rotatably connected to an inner member and to a top member. Inner members are connected by a first hinge, and top members are connected by a second hinge, so that when inner and top members are fully rotatably misaligned with respect to the outer pair, the first and second hinges can be opened to allow the inner and outer members to form a tripod. When open, inner members can engage top members to support the top members in an elevated horizontal plane to provide a stable surface for supporting an elongated structure or instrument such as an electric piano. When closed, outer members align in parallel to form a retracting channel for the inner and top members.

主权项

1. An interretractable stand, comprising:
outer and inner pairs of mirror-image members; each member of the outer pair rotatably connected to a member of the inner pair; and the members of the outer pair hingedly connected, and the members of the inner pair hingedly connected, so that the inner pair when fully rotatably misaligned with respect to the outer pair allows the inner and outer pairs to be hingedly separated to an open position, and so that the inner pair when fully rotatably aligned with respect to the outer pair rests between members of the outer pair in a closed position.
