Abstract

A frame holding device holds an embroidery frame provided with a first frame and a second frame. The second frame includes a mounting portion. The frame holding device includes a fixing portion, a base portion, an engaging portion, and a regulation portion. The base portion is connected to the fixing portion. The base portion extends in a first direction and includes a placement surface. The engaging portion is configured to engage with an engaged portion provided on the mounting portion. The regulation portion is configured to restrict the second frame from moving in a third direction by coming into contact with the mounting portion in a state in which the engaged portion and the engaging portion are engaged with each other. The third direction is a direction intersecting with the first direction and the placement surface.

First claim

What is claimed is:

1. A frame holding device that holds an embroidery frame of a sewing machine, the frame holding device comprising:
a fixing portion configured to be detachably fixed to a working table;
a base portion connected to the fixing portion, the base portion extending in a first direction toward the fixing portion, the base portion including a placement surface, the embroidery frame including a first frame and a second frame, the embroidery frame being configured to hold a sewing object between the first frame and the second frame, and the second frame being configured to be placed on the placement surface;
an engaging portion configured to engage with an engaged portion, the engaged portion being provided on a mounting portion, the mounting portion being included in the second frame and being configured to be detachably mounted on the sewing machine, the engaging portion being configured to restrict the second frame placed on the placement surface from moving in the first direction and a second direction after engaging with the engaged portion, and the second direction being a direction opposite to the first direction; and
a regulation portion provided further to a third direction side than the placement surface, the third direction being a direction intersecting with the first direction and the placement surface, and the regulation portion being configured to restrict the second frame from moving in the third direction, by coming into contact, from the third direction, with the mounting portion in a state in which the engaged portion and the engaging portion are engaged with each other.

2. The frame holding device according to claim 1 , further comprising:
a specific magnet provided on a back surface of the base portion, the back surface being on an opposite side to the placement surface, and the specific magnet being configured to be attracted to a magnetic body in the state in which the engaged portion and the engaging portion are engaged with each other, the first frame including a magnet, the second frame including the magnetic body, the embroidery frame being configured to clamp the sewing object between the first frame and the second frame using a magnetic force.

3. The frame holding device according to claim 2 , further comprising:
a yoke which is attached to the back surface and to which the specific magnet is fixed,
wherein
an end portion on the third direction side of the yoke is inserted into a hole portion provided in the base portion from the back surface side toward the placement surface side, and is exposed from the placement surface toward the third direction side.

4. The frame holding device according to any one of claim 1 , further comprising:
an urging portion provided further to the first direction side than the engaging portion, the urging portion being configured to urge the second frame in the second direction in the state in which the engaged portion and the engaging portion are engaged with each other.

5. The frame holding device according to claim 1 , wherein
the fixing portion includes
a vertical wall portion extending in the third direction,
an upper wall portion extending in the first direction from one end portion of the vertical wall portion in the third direction, the upper wall portion being configured to come into contact with an upper surface of the working table, and
a clamping portion connected to another end portion that is on an opposite side to the one end portion of the vertical wall portion, the clamping portion being configured to clamp, from below, the working table between the clamping portion and the upper wall portion, and

the base portion includes
a first connection portion connected to the upper wall portion, and
a second connection portion connected to the vertical wall portion.

6. The frame holding device according to claim 1 , wherein
the regulation portion includes
a flat plate portion configured to be elastically deformed, the flat plate portion having a plate shape that extends in a fourth direction, the fourth direction being a direction parallel to the placement surface and being a direction orthogonal to the first direction and the third direction, and
a contact portion protruding from the flat plate portion toward the placement surface side, and the contact portion being configured to come into contact with the mounting portion from the third direction.

7. The frame holding device according to claim 1 , wherein
the regulation portion includes
an inclined portion that is inclined toward the placement surface side as the inclined portion extends toward the first direction, the inclined portion being configured to come into contact with the mounting portion.

8. The frame holding device according to claim 1 , further comprising:
a guide portion provided further to the first direction side than the engaging portion, and configured to guide the mounting portion of the second frame in the first direction.

9. The frame holding device according to claim 8 , further comprising:
a restriction portion provided on an end portion on the second direction side of the guide portion, the guide portion being formed in a plate shape that is parallel to the first direction and being provided at a position at which the mounting portion of the second frame is to be clamped from both sides in a fourth direction, the fourth direction being a direction orthogonal to the first direction and the third direction, and the restriction portion being configured to restrict the movement of the second frame in the first direction, by coming into contact with a stopper provided further to the second direction side of the second frame than the mounting portion.

10. The frame holding device according to claim 1 , further comprising:
an inclined guide portion provided further to the second direction side than the engaging portion and inclined from the placement surface toward a stepped portion, the stepped portion being provided further to the third direction side than the placement surface, the engaging portion being provided on the stepped portion, and the inclined guide portion being configured to guide the mounting portion toward the stepped portion side.

11. The frame holding device according to claim 1 , wherein
the base portion includes an indicator provided in a predetermined region of the placement surface, the indicator being one of a concave portion, a convex portion and a hole portion, the indicator being positioned on the inside of the second frame in a state in which the second frame is placed on the placement surface and the engaged portion and the engaging portion are engaged with each other, and the indicator indicating a reference of an arrangement position of the sewing object with respect to the second frame.

12. The frame holding device according to claim 11 , wherein
the base portion includes a center indicator provided in the predetermined region, the center indicator indicating a center position of the inside of the second frame when the engaged portion and the engaging portion are engaged with each other.

13. The frame holding device according to claim 1 , wherein
the base portion includes
a main body portion having the placement surface and extending in the first direction,
a pair of side portions extending in the first direction, one of the pair of side portions being provided on one end portion in a fourth direction of the main body portion, the other of the pair of side portions being provided on the other end portion in the fourth direction of the main body portion, the fourth direction being a direction orthogonal to the first direction and the third di
