  • Patent number: 11390974
    Abstract: An embroidery frame includes an inner frame formed like a hoop and an outer frame that has a separation section at which the outer frame is separated so as to form a first end portion and a second end portion that oppose each other. The outer frame is configured to nip an embroidery object, in collaboration with the inner frame, from outside the inner frame. The embroidery frame also includes an opening-closing mechanism configured to adjust a clearance of the separation section. In the embroidery frame, the opening-closing mechanism has a connection shaft that connects the first end portion and the second end portion to each other and also has a manipulation member that is rotatably mounted on the connection shaft with a center of rotation being positioned at the first end portion.
