Title: Presser foot elevating device for sewing machine
Inventor: SAKAI KATSUAKI
IPC: D05B39/00
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To enable a cloth to be positioned against a presser foot securely in a short time to improve the sewing work efficiency by equipping the presser foot vertically movable at an arbitrary position corresponding to the stepping amount of the foot pedal. SOLUTION: A cloth 9 is set first in between a lower plate 8 and a presser foot 6 on sewing work of the cloth 9. A foot pedal is gradually stepped in that condition and a cylinder rod 21 is pushed down against the pressure of air from an air source 25 decompressed by a decompressor 35. The pressure in the first chamber 18a of an operation cylinder 18 is decompressed by pushing down the cylinder rod 21 to decompress the pressure in the second chamber 12b of a pressing cylinder 12 through an air tube 30. Thus a cylinder rod 14 is gradually moved toward left and the presser foot 6 is gradually descended corresponding to the stepping amount of the foot pedal 22 through a pressing link 16. Then the foot pedal 22 is stepped deeper to press and hold the cloth 9 by the presser foot 6.
