Mechanically operated presser foot lift arrangement and a sewing machine comprising the arrangement
Abstract:
The invention relates to a mechanically operated presser foot lift arrangement (2) comprising a presser bar (14) with a presser foot (15) and a presser foot lift (16) having a body (17) and a handle (18). The body (18) comprises a guiding means (21). An actuating means (23) connected to the presser bar is arranged to be guided along the guiding means on rotation of the body about a shaft (19). The guiding means cooperates with a first locking means (26) for locking the actuating means in a position corresponding to a first lifting height of the presser bar. The arrangement comprises also a displaceable means (27) having a second locking means (28), which may be brought into and out of cooperation with the guiding means. When positioned in cooperation with the guiding means, the second locking means is arranged for locking the actuating means in a position corresponding to a second lifting height of the presser bar.
