An embroidery frame includes a mounting portion to be mounted on a sewing machine and a frame portion. The frame portion has a first frame, a hinge portion, a second frame, a first clamping portion, and a second clamping portion. The first frame is connected to the mounting portion. The hinge portion is connected to one end of the first frame. The second frame is connected at one end to the hinge portion such that the second frame is able to rotate with respect to the first frame. The first clamping portion is configured to clamp the first sewing object together with the first frame while the second frame is open with respect to the first frame. The second clamping portion is configured to clamp the second sewing object together with the second frame while the second frame is open with respect to the first frame.

Embroidery frame

An embroidery frame includes a mounting portion, a first frame with a magnet, and a second frame with a main body portion and a guide portion. The mounting portion is configured to be removably mounted on a sewing machine. The main body portion includes a clamping surface. The guide portion is configured by a non-magnetic material, is provided on the clamping surface, includes an inclined surface, protrudes further than the clamping surface in a first direction intersecting the clamping surface, and guides the first frame to the clamping surface. The inclined surface is inclined in a direction opposite to the first direction the further the inclined surface extends in a second direction that is orthogonal to the first direction and is from an outer side toward an inner side of the second frame. The second frame can clamp easily a sewing object, with the first frame, using magnetic force.

An embroidery frame includes a pair of a first frame and a second frame configured to clamp a sewing object, and a lock mechanism. The lock mechanism is configured to switch a position of the second frame with respect to the first frame to at least three positions including a first position, a second position and a third position. The first position is a position in which the second frame is closed with respect to the first frame. The second position is a position in which, with respect to the first frame, the second frame is more open, by a first predetermined amount, than in the first position. The third position is a position in which, with respect to the first frame, the second frame is open by a second predetermined amount. The second predetermined amount is larger than the first predetermined amount.
