Abstract

A sewing machine presser foot includes: a presser foot body including an attachment portion attached to a presser bar of a sewing machine, a supporting portion extending downward from the attachment portion , and a pressing portion in which, at a lower end of the supporting portion, a needle guiding hole having a string guiding groove for guiding a string is formed; and a cover member including a groove covering portion that crosses and covers the string guiding groove of the pressing portion, a supporting plate portion formed along the supporting portion continuously from the groove covering portion, and an attachment portion formed at an end of the supporting plate portion so as to be attached to the presser foot body. A right-side portion of the supporting plate portion of the cover member is fixed to the presser foot body A by the attachment portion.

First claim

What is claimed is:

1. A sewing machine presser foot, comprising:
a presser foot body including an attachment portion attached to a presser bar of a sewing machine, a supporting portion extending downward from the attachment portion, and a pressing portion in which, at a lower end of the supporting portion, a needle guiding hole including a string guiding groove for guiding a string is formed; and
a cover member including a groove covering portion that crosses and covers the string guiding groove of the pressing portion, a supporting plate portion formed along the supporting portion continuously from the groove covering portion, and another attachment portion formed at an end of the supporting plate portion so as to be attached to the supporting portion of the presser foot body,
wherein a right-side portion of the supporting plate portion of the cover member fixed to the presser foot body by the attachment portion is configured to be displaced from the supporting portion.

2. The sewing machine presser foot according to claim 1 , wherein a bent portion provided in the supporting plate portion is formed to be bent in such a direction that the supporting plate portion is displaced from the supporting portion in a left-right direction of the supporting plate portion of the cover member.

3. The sewing machine presser foot according to claim 1 , wherein a string guide is formed to be erected continuously from the groove covering portion of the cover member so as to correspond to a thread insertion opening of the string guiding groove of the pressing portion.

4. The sewing machine presser foot according to claim 1 , wherein a front-rear deflection restricting portion is provided in the supporting plate portion of the cover member fixed to the supporting portion of the presser foot body, the front-rear deflection restricting portion restricting deflection of the supporting plate portion in a front-rear direction and including a rear restricting plate that is bent toward a rear side of the supporting portion and is positioned so as to be separated from a rear surface of the supporting portion.

5. The sewing machine presser foot according to claim 1 , wherein the supporting portion and the attachment portion are integrally formed by bending a metal plate.

6. The sewing machine presser foot according to claim 1 , wherein the supporting portion and the attachment portion are integral parts of a single metal plate.

7. The sewing machine presser foot according to claim 1 , wherein an entirety of the presser foot body is a single plate that includes the supporting portion and the attachment portion.

8. The sewing machine presser foot according to claim I, wherein the attachment portion of the presser foot body abuts said another attachment portion of the cover member.

9. The sewing machine presser foot according to claim 1 , wherein a surface of the attachment portion of the presser foot body contacts a surface of said another attachment portion of the cover member.

10. The sewing machine presser foot according to claim 1 , wherein, in a side view, the supporting portion continuously extends downward from the attachment portion.

11. The sewing machine presser foot according to claim 1 , wherein, in a side view, a surface of the supporting portion is flush with a surface of the attachment portion.

12. The sewing machine presser foot according to claim 1 , wherein a front-rear deflection restricting portion is provided in the supporting plate portion of the cover member fixed to the supporting portion of the presser foot body.

13. The sewing machine presser foot according to claim 12 , wherein the front-rear deflection restricting portion restricts deflection of the supporting plate portion in a front-rear direction.

14. The sewing machine presser foot according to claim 12 , wherein the front-rear deflection restricting portion includes a rear restricting plate that is bent toward a rear side of the supporting portion.

15. The sewing machine presser foot according to claim 12 , wherein the front-rear deflection restricting portion includes a rear restricting plate that is positioned to be separated from a rear surface of the supporting portion.

16. A sewing machine presser foot, comprising:
a presser foot body including an attachment portion attached to a presser bar of a sewing machine, a supporting portion extending downward from the attachment portion, and a pressing portion in which, at a lower end of the supporting portion, a needle guiding hole including a string guiding groove for guiding a string is formed; and
a cover member including a groove covering portion that crosses and covers the string guiding groove of the pressing portion, a supporting plate portion formed along the supporting portion continuously from the groove covering portion, and another attachment portion formed at an end of the supporting plate portion so as to be attached to the presser foot body,
wherein a right-side portion of the supporting plate portion of the cover member fixed to the presser foot body by the attachment portion is configured to be displaced from the supporting portion, and
wherein a front-rear deflection restricting portion is provided in the supporting plate portion of the cover member fixed to the supporting portion of the presser foot body; the front-rear deflection restricting portion restricting deflection of the supporting plate portion in a front-rear direction and including a rear restricting plate that is bent toward a rear side of the supporting portion and is positioned so as to be separated from a rear surface of the supporting portion.
