Abstract

A presser foot device includes a wall portion, a pair of opposed portions, a pin, and an abutting portion. The wall portion extends in a first direction and a second direction intersecting the first direction. The pair of opposed portions extend in one direction of a third direction intersecting the first direction and the second direction from the wall portion, and face each other. The pin extends in the second direction between the pair of opposed portions, and engages with a groove provided in the presser foot holder. The abutting portion is provided with respect to the pin on one direction side of the first direction, and is provided on the one direction side of the third direction of an end surface in the one direction of the third direction, of the pair of opposed portions. The abutting portion abuts against the pressor foot holder in the second direction.

Claims

1. A presser foot device mounted to a pressor foot holder of a sewing machine, comprising:

a wall portion extending in a first direction and a second direction, the first direction intersecting the second direction;

a pair of opposed portions extending in one direction of a third direction from the wall portion, and facing each other, the third direction intersecting the first direction and the second direction;

a pin extending in the second direction between the pair of opposed portions, and being configured to engage with a groove provided in the presser foot holder; and

an abutting portion provided with respect to the pin on one direction side of the first direction, and provided on the one direction side of the third direction of an end surface in the one direction of the third direction, of the pair of opposed portions, the abutting portion being configured to abut against the pressor foot holder in the second direction.

2. The presser foot device according to claim 1, wherein

the abutting portion extends in the one direction of the third direction from the opposed portions.

3. The presser foot device according to claim 1, wherein

the abutting portion is longer than the pair of opposed portions, in the third direction.

4. The presser foot device according to claim 1, wherein

the abutting portion is shorter than the pair of opposed portions, in the first direction.

5. The presser foot device according to claim 1, wherein

the abutting portion includes a first end portion that is an end portion in the one direction of the first direction, and

the first end portion is on the one direction side of the first direction, of an end portion in the one direction of the first direction, of the opposed portions.

6. The presser foot device according to claim 1, wherein

the abutting portion includes a specific wall portion and a protruding portion,

the specific wall portion is provided on the one direction side of the third direction, of the end surface of the opposed portions, and

the protruding portion protrudes from the specific wall portion in a direction toward the center position between the pair of opposed portions, in the second direction, and abuts against the presser foot holder in the second direction.

7. The presser foot device according to claim 6, wherein

the protruding portion includes an inclined surface that inclines toward the side in the direction in which the protruding portion protrudes, farther toward another direction that is a direction opposite the one direction of the third direction.

8. The presser foot device according to claim 1, further comprising:

a holder portion holding the wall portion so as to enable the wall portion to move in the first direction, and including an opening that opens toward the one direction of the third direction, both end portions in the second direction of the opening extending in the first direction; and

an insertion portion extending from the wall portion in another direction that is a direction opposite the one direction of the third direction, and being inserted into the opening and abutting against both of the end portions of the opening.

9. The presser foot device according to claim 8, wherein

the insertion portion is provided in a same position as at least a portion of the abutting portion, in the first direction.

10. The presser foot device according to claim 1, wherein

when the abutting portion is mounted on the presser foot holder, at least a portion of the abutting portion is on the one direction side of the first direction, of a presser bar of the sewing machine that holds the presser foot holder.

11. The presser foot device according to claim 1, wherein

when the abutting portion is mounted on the presser foot holder, the abutting portion is on another direction side, which is a side in a direction opposite the one direction of the first direction, of an end portion in the one direction of the first direction, of the presser foot holder.

12. The presser foot device according to claim 1, wherein

the abutting portion is a pair of the abutting portions provided one on each of the end surfaces of the pair of opposed portions.

13. The presser foot device according to claim 6, wherein

the protruding portion includes an inclined surface extending toward another direction that is a direction opposite the one direction of the third direction, and in the direction in which the protruding portion protrudes.
