Abstract

A presser device includes an attachment body, an adjustment member, and a presser body. The attachment body includes an attachment portion and a shaft. The attachment portion is attached to a presser bar included in a sewing machine and extending in a first direction. The shaft extends in a second direction that intersects the first direction. The adjustment member is configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction. The presser body includes an insertion hole and an insertion portion, the insertion hole penetrating in the first direction. The insertion portion is configured such that the shaft is inserted therethrough. The presser body is configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member.

First claim

What is claimed is:

1. A presser device comprising:
an attachment body including an attachment portion and a shaft, the attachment portion being configured to be attached to a presser bar included in a sewing machine and extending in a first direction, and the shaft extending in a second direction that intersects the first direction;
an adjustment member configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction, the adjustment member having an engagement portion on a distal end in the second direction, the engagement portion being configured to be engaged with a jig used to rotate the adjustment member, the one end of the shaft on which the adjustment member is configured to be screwed onto having a diameter that is less than the diameter of a remainder of the shaft; and
a presser body including an insertion hole and an insertion portion, the insertion hole penetrating in the first direction, the insertion portion being configured such that the shaft is inserted therethrough, and the presser body being configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member.

2. The presser device according to claim 1 , wherein
the adjustment member is fixed to the presser body, and
in a state in which a relative position of the presser body and the adjustment member in the second direction is maintained at a same position, a relative position of the shaft of the attachment body and the adjustment member in the second direction is changed in accordance with the rotation of the adjustment member.

3. The presser device according to claim 1 , further comprising:
a suppression body configured to come into contact with the adjustment member and to suppress the rotation of the adjustment member.

4. A presser device comprising:
an attachment body including an attachment portion and a shaft, the attachment portion being configured to be attached to a presser bar included in a sewing machine and extending in a first direction, and the shaft extending in a second direction that intersects the first direction;
an adjustment member configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction;
a presser body including an insertion hole and a through hole, the insertion hole penetrating in the first direction, the through hole being configured such that the shaft is inserted therethrough, and the presser body being configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member; and
a suppression body configured to come into contact with the adjustment member and to suppress the rotation of the adjustment member, the suppression body including an engagement portion and a recessed portion, the engagement portion being configured to engage with the adjustment member such that the adjustment member is rotatable, the recessed portion being recessed in a third direction that intersects both the first direction and the second direction, and the suppression body being configured to hold the presser body such that the attachment body and the presser body are disposed in the recessed portion.

5. The presser device according to claim 4 , wherein
the adjustment member includes a first wall portion and a second wall portion that are arranged side by side in the second direction, and is engaged with the engagement portion between the first wall portion and the second wall portion.

6. The presser device according to claim 4 , further comprising:
a rotation stopper member connected to the attachment body and configured to restrict the rotation of the presser body around the shaft.

7. The presser device according to claim 4 , wherein
the attachment body includes a guide configured to guide a cord to the insertion hole from one side in the second direction with respect to the insertion hole.

8. The presser device according to claim 4 , wherein
the attachment body includes
a first face, when the attachment portion is attached to the presser bar, arranged on one side of the presser bar in the second direction,
a second face, when the attachment portion is attached to the presser bar, arranged on one side of the presser bar in the third direction,
a third face, when the attachment portion is attached to the presser bar, arranged on another side of the presser bar in the third direction, and
a first through hole which penetrates in the second direction and through which the shaft is inserted.

9. The presser device according to claim 4 , wherein
the adjustment member has a screw portion provided at an end portion of the adjustment member in a fourth direction opposite to the second direction.

10. A presser device comprising:
an attachment body including an attachment portion and a shaft, the attachment portion being configured to be attached to a presser bar included in a sewing machine and extending in a first direction, and the shaft extending in a second direction that intersects the first direction;
an adjustment member configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction;
a presser body including an insertion hole and an insertion portion, the insertion hole penetrating in the first direction, the insertion portion being configured such that the shaft is inserted therethrough, and the presser body being configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member; and
a rotation stopper member connected to the attachment body and configured to restrict the rotation of the presser body around the shaft, wherein
the presser body has a long hole that extends in the second direction, and
the rotation stopper member is inserted through the long hole and is connected to the attachment body.

11. The presser device according to claim 10 , wherein
the attachment body includes
the shaft extending in the second direction and having a hole,
a first through hole which penetrates in the second direction and through which the shaft is inserted, and
a second through hole connected to the first through hole and extending in a third direction that intersects both the first direction and the second direction, and

the rotation stopper member is inserted through the long hole of the presser body and the second through hole, and is inserted into the hole provided in the shaft.
