ABSTRACT:
A presser foot coupler for a sewing machine allows effortless and quick mounting and dismounting of a presser foot onto the sewing machine. The presser foot coupler comprise a holding member having a receding coupling portion formed on the bottom and a sliding channel formed on one side, and a locking member slidably inserted in the sliding channel on the holding member so as to allow the presser foot to be locked in position with the holding member. To allow a presser foot to be mountable on the presser foot coupler according to the present invention, the presser foot should be formed with at least a projecting coupling portion on the top. The receding coupling portion on the holding member then allows the presser foot to be coupled to the holding member by inserting the projecting coupling portion into the receding coupling portion. Either the dismounting or the mounting is quite effortless and quick to do, thus allowing very easy replacement of the presser foot on the sewing machine.
