Abstract

A sewing machine guiding tool includes a presser foot, a holder and a gauge. The presser foot includes a bottom wall and a rear support. The bottom wall is formed with a needle-passing hole and with a slit extending from the needle-passing hole to the front end of the bottom wall. The rear support is connected to the rear end of the bottom wall. The holder, attached to a presser bar of the sewing machine, holds the presser foot pivotally about a horizontal axis. The gauge, supported by the rear support to be slidable in parallel to the horizontal axis, includes a ruler plate and a guide portion. The ruler plate has a surface marked with a scale. The guide portion extends from the ruler plate. The ruler plate is disposed above the bottom wall with its surface inclined to become higher as proceeding rearward.

First claim

The invention claimed is:

1. A guiding tool for a sewing machine, the guiding tool comprising:
a presser foot including a bottom wall and a rear support, the bottom wall including a front end and a rear end, the bottom wall being formed with a needle-passing hole between the front end and the rear end, the bottom wall being formed with a slit extending from the needle-passing hole to the front end, the rear support being held in direct contact with and connected to the rear end of the bottom wall;
a holder that is removably attached to a presser bar of the sewing machine and that holds the presser foot in a manner such that the presser foot together with the rear support is capable of pivoting about a horizontal axis; and
a gauge supported by the rear support in a manner slidable in a first direction parallel to the horizontal axis, the gauge including a ruler plate and a guide portion, the ruler plate having a ruler surface marked with a scale, the guide portion extending from the ruler plate,
wherein the ruler plate is disposed above the bottom wall in a vertical direction, and the ruler surface is inclined so as to become higher as proceeding rearward.

2. The guiding tool according to claim 1 , wherein the guide portion extends forward from an end of the ruler plate, and
the guide portion includes a distal portion and a proximal portion that is closer to the end of the ruler plate than is the distal portion, the distal portion being dislocated relative to the proximal portion in the first direction.

3. The guiding tool according to claim 2 , wherein the presser foot includes a side wall connected to a side edge of the bottom wall.

4. The guiding tool according to claim 3 , wherein the side wall includes a recessed portion accommodating the distal portion of the guide portion.

5. The guiding tool according to claim 1 , further comprising an engagement member configured to allow stepwise sliding movement of the ruler plate.

6. The guiding tool according to claim 5 , wherein the ruler plate is formed with irregularities arranged in a row, and
the engagement member comprises an engagement portion and a button, the engagement portion being capable of resilient engagement with the irregularities, the button being capable of switching a position of the engagement portion between a state in which the engagement portion engages the irregularities and another state in which the engagement portion does not engage the irregularities.

7. The guide tool according to claim 6 , wherein the button is disposed on an opposite side of the presser foot relative to the guide portion, in the first direction.
