Abstract

An embroidery frame transport device includes a carriage, a guide portion, a rotation shaft, and a lock release lever including a first restricting portion and a contact portion. The lock release lever is configured to rotate to a first position and a second position around the rotation shaft. The first restricting portion contacts the coupling portion to restrict an embroidery frame from moving in a removing direction by moving to the first position when the embroidery frame is moved in a mounting direction in a process of mounting the coupling portion on the carriage. The contact portion contacts the coupling portion and presses the embroidery frame in the removing direction as a result of the lock release lever moving to a third position when the lock release lever is rotated in a releasing direction while the coupling portion is mounted on the carriage.

First claim

What is claimed is:

1. An embroidery frame transport device comprising:
a carriage configured to detachably mount with a coupling portion of an embroidery frame;
a guide portion provided on the carriage, the guide portion being configured to define a mounting direction and a removing direction of the embroidery frame;
a rotation shaft provided at a position facing the guide portion of the carriage; and
a lock release lever including a first restricting portion and a contact portion, the lock release lever being configured to rotate to a first position and a second position around the rotation shaft, the first restricting portion contacting the coupling portion to restrict the embroidery frame from moving in the removing direction by moving to the first position when the embroidery frame is moved in the mounting direction in a process of mounting the coupling portion on the carriage, and the contact portion contacting the coupling portion and pressing the embroidery frame in the removing direction as a result of the lock release lever moving to a third position between the first position and the second position when the lock release lever is rotated in a releasing direction toward the second position from the first position while the coupling portion is in a state mounted on the carriage.

2. The embroidery frame transport device according to claim 1 , further comprising:
a first urging member configured to urge the lock release lever in a locking direction toward the first position from the second position around the rotation shaft, the first urging member being provided on the carriage; and
a second urging member configured to urge the coupling portion mounted on the carriage in the removing direction, the second urging member being provided on the carriage,
wherein
the lock release lever contacts the coupling portion and rotates in the releasing direction against the urging force of the first urging member when the embroidery frame is moved in the mounting direction in the process of mounting the coupling portion on the carriage, and rotates to the first position by the urging force of the first urging member and restricts the coupling portion from moving in the mounting direction and the removing direction with the second urging member and the first restricting portion, when the coupling portion is moved to a mounting position.

3. The embroidery frame transport device according to claim 2 , further comprising:
a second restricting portion configured to restrict the lock release lever from moving in the releasing direction beyond the first position by abutting against the lock release lever when the lock release lever is in the first position, the second restricting portion being provided on the carriage.

4. The embroidery frame transport device according to claim 1 , wherein
the lock release lever further includes a lever portion configured to assume a posture extending in the removing direction from the rotation shaft and following an extending direction of the guide portion when the lock release lever is in the first position, and
the first restricting portion comes into contact with an end portion in the removing direction of the coupling portion.

5. The embroidery frame transport device according to claim 4 , wherein
the first restricting portion is provided on an end portion on the rotation shaft side of the lever portion, the first restricting portion being configured to come into contact with the end portion in the removing direction of the coupling portion.

6. The embroidery frame transport device according to claim 1 , further comprising:
a third urging member provided at a position facing the guide portion of the carriage, the third urging protruding toward the guide portion side; and
a fourth urging member provided on the second urging member side with respect to the third urging member, at a position facing the guide portion of the carriage, the fourth urging member protruding farther toward the guide portion side than the third urging member,
wherein
when the coupling portion is positioned in the mounting position, the third urging member and the fourth urging member each contact the coupling portion and urge the coupling portion toward the guide portion side.

7. The embroidery frame transport device according to claim 6 , wherein
the third urging member and the fourth urging member each separate from the coupling portion when the lock release lever is rotated from the first position to the second position in a state in which the coupling portion is positioned in the mounting position.
