Abstract

An embroidery frame includes a lower holding member, an upper holding member, and a first adjustment mechanism. The lower holding member is configured such that a sewing workpiece is placed on the lower holding member. The upper holding member is configured to press from above on the sewing workpiece that is placed on the lower holding member. The first adjustment mechanism is configured to adjust a distance between the lower holding member and the upper holding member in a state in which the upper holding member is pressing from above on the sewing workpiece that is placed on the lower holding member.

First claim

What is claimed is:

1. An embroidery frame comprising:
a lower holding member that is configured such that a sewing workpiece is placed on the lower holding member;
an upper holding member that is configured to press from above on the sewing workpiece that is placed on the lower holding member, the upper holding member including:
a support member having one edge portion of the support member being pivotally supported by the lower holding member, and
a pressing member provided with a first pressing member and a second pressing member configured to press on areas that are located on opposite sides of a rectangular sewable area of the sewing workpiece that is placed on the lower holding member; and

a first adjustment mechanism that is configured to adjust a distance between the lower holding member and the upper holding member in a state in which the upper holding member is pressing from above on the sewing workpiece that is placed on the lower holding member, wherein:
the pressing member includes a portion that extends from another edge portion on an opposite side of the support member from the one edge portion and being a member that is configured, by adjusting the distance between the lower holding member and the upper holding member by the first adjustment mechanism to press on the sewing workpiece that is placed on the lower holding member, and
the first pressing member and the second pressing member are each rod-shaped members and are each provided with support portions and pressing portions, the support portions being portions that extend from the one edge portion to the other edge portion of the support member and that are supported by the support member, the pressing portions being members that are bent in relation to the support portions, that extend parallel to the long axis of the sewable area and outside of the sewable area, and that are configured to press on the sewing workpiece that is placed on the lower holding member.

2. The embroidery frame according to claim 1 , wherein
the first adjustment mechanism is provided with a first screw portion and a nut portion, the first screw portion being a screw portion with one end anchored to the lower holding member and another end passing through the support member, the nut portion being a nut portion that is configured to adjust a distance between the pressing member and the lower holding member by being screwed onto the first screw portion.

3. The embroidery frame according to claim 2 , further comprising:
another first screw portion and another nut portion, wherein
one of the first screw portion and one of the nut portion being provided on a side of the support member where the first pressing member extends from the other edge portion of the support member, and
the other of the first screw portion and the other of the nut portion being provided on a side of the support member where the second pressing member extends from the other edge portion of the support member.

4. The embroidery frame according to claim 1 , further comprising:
a second adjustment mechanism that is configured to adjust inclinations of the pressing portions in relation to a carrying portion, the carrying portion being a portion that is provided in the lower holding member, with a top face that is flat, and on which the sewing workpiece is placed.

5. The embroidery frame according to claim 4 , wherein
the second adjustment mechanism is provided with a second screw portion, the second screw portion being a screw portion that is screwed into the support member and that is configured to adjust the inclinations of the pressing portions in relation to the carrying portion by rotating the pressing portions around the support portions.

6. The embroidery frame according to claim 1 , further comprising:
an indicator portion that, in a case where the sewing workpiece is a shoe, serve as indicators of the position where the shoe is placed on the lower holding member.

7. A sewing machine comprising:
an embroidery frame that is provided with a lower holding member that is configured such that a sewing workpiece is placed on the lower holding member;
an upper holding member that is configured to press from above on the sewing workpiece that is placed on the lower holding member, the upper holding member including:
a support member having one edge portion of the support member being pivotally supported by the lower holding member, and
a pressing member provided with a first pressing member and a second pressing member configured to press on areas located on opposite sides of a rectangular sewable area of the sewing workpiece that is placed on the lower holding member; and

a first adjustment mechanism that is configured to adjust a distance between the lower holding member and the upper holding member in a state in which the upper holding member is pressing from above on the sewing workpiece that is placed on the lower holding member, wherein:
the pressing member includes a portion that extends from another edge portion on an opposite side of the support member from the one edge portion and being a member that is configured, by the adjusting of the distance between the lower holding member and the upper holding member by the first adjustment mechanism, to press on the sewing workpiece that is placed on the lower holding member, and
the first pressing member and the second pressing member are each rod-shaped members and are each provided with support portions and pressing portions, the support portions being portions that extend from the one edge portion to the other edge portion of the support member and that are supported by the support member, the pressing portions being members that are bent in relation to the support portions, that extend parallel to the long axis of the sewable area and outside of the sewable area, and that are configured to press on the sewing workpiece that is placed on the lower holding member.

8. The sewing machine according to claim 7 , wherein
the first adjustment mechanism is provided with a first screw portion and a nut portion, the first screw portion being a screw portion with one end anchored to the lower holding member and another end passing through the support member, the nut portion being a nut portion that is configured to adjust a distance between the pressing member and the lower holding member by being screwed onto the first screw portion.

9. The sewing machine according to claim 8 , further comprising:
another first screw portion and another nut portion, wherein
one of the first screw portion and one of the nut portion being provided on a side of the support member where the first pressing member extends from the other edge portion of the support member,
the other of the first screw portion and the other of the nut portion being provided on a side of the support member where the second pressing member extends from the other edge portion of the support member.

10. The sewing machine according to claim 7 , wherein
the embroidery frame is further provided with a second adjustment mechanism that is configured to adjust inclinations of the pressing portions in relation to a carrying portion, the carrying portion being a portion that is provided in the lower holding member, with a top face that is flat, and on which the sewing workpiece is placed.

11. The sewing machine according to claim 10 , wherein
the second adjustment mechanism is provided with a second screw portion, the second screw portion being a screw portion that is screwed into the support member and that is configured to adjust the inclinations of the pressing portions in relation to the carrying portion by rotating the pressing portions around the support p
