Sewing machine ankle assemblies having a resilient member for attaching a presser foot

A sewing machine ankle assembly comprising:

• an ankle comprising an upper portion and a lower portion, wherein the lower portion defines at least one structure configured to receive an attachment mechanism of a presser foot;
• and
• a resilient member comprising an upper end and an opposing lower end, wherein the upper end is attached to the ankle, and wherein the lower end is positioned beneath a portion of the attachment mechanism of the presser foot when the attachment mechanism is received by the at least one structure of the ankle such that the lower portion of the resilient member exerts a force in a direction towards the at least one structure of the ankle for holding the portion of the attachment mechanism together with the at least one structure of the ankle,
• wherein the at least one structure of the ankle and the lower end of the resilient member form an opening that faces a substantially horizontal direction for receipt and release of the attachment mechanism of the presser foot along the substantially horizontal direction, and
• wherein the at least one structure comprises a plurality of notches that face in a substantially downward direction.

A sewing machine ankle and presser foot system comprising

• an ankle comprising an upper portion and a lower portion;
• a resilient member comprising an upper end and an opposing lower end;
• a presser foot arranged to be engaged with the ankle,
• wherein the lower portion of the ankle defines at least one structure configured to receive an attachment mechanism of the presser foot, and
• wherein the upper end of the resilient member is attached to the ankle, and wherein the lower end is positioned beneath a portion of the attachment mechanism of the presser foot when the attachment mechanism is received by the at least one structure of the ankle such that the lower portion of the resilient member exerts a force on the portion of the attachment mechanism in a direction towards the at least one structure of the ankle for holding the portion of the attachment mechanism together with the at least one structure of the ankle,
• wherein the at least one structure of the ankle and the lower end of the resilient member form an opening that faces a substantially horizontal direction for receipt and release of the attachment mechanism of the presser foot along the substantially horizontal direction, and
• wherein the at least one structure comprises a plurality of notches that face in a substantially downward direction, wherein the notches each have a concave shape configured to receive the attachment mechanism of the presser foot, wherein the concave shape corresponds to the shape of a crossbar of the presser foot.
