Apparatus for mounting and removing the supporting frame of a quilt or the like in sewing machines

摘要

A pair of left and right guide rails and a pair of left and right supporting rails which support the supporting frame of a quilt or the like, are provided with a pivot on one side of the sewing machine to permit circular movement. These rails are parallel to each other. A moving member is provided along the guide rails, and this moving member is moved by a moving apparatus. An anchoring member is also provided to anchor the member to the supporting frame. Furthermore, an apparatus for moving up and down, which allows the guide rails and the supporting rails to move in a circular manner using the pivot as a fulcrum, is provided to anchor the anchoring members of the supporting frame or to release the anchoring.
