Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap frame for a sewing machine, and more particularly to a cap frame that is easily mounted on the cap frame when the cap is mounted in a desired state without loosening.

[0002]

2. Description of the Related Art Conventionally, in a multi-needle type embroidery sewing machine capable of embroidering with embroidery threads of a plurality of colors, a cloth to be sewn is set on an embroidery frame, and the embroidery frame is moved in the X-axis direction and the Y-axis direction (arm portion of the embroidery sewing machine). Embroidery sewing is executed in a state where the embroidery sewing machine is attached to a movable frame that is independently driven in the direction (parallel to the) By the way, a cap frame device connected to the X-axis drive mechanism and the Y-axis drive mechanism of the embroidery sewing machine is used to embroider on the front surface of the cap.

This hat frame device comprises a hat frame drive section and a hat frame which is detachably attached to the hat frame drive section with the hat attached. The hat frame drive section is generally composed of a base frame driven in the Y-axis direction and a rotation frame rotatably supported by the base frame and driven to rotate about an axis parallel to the Y-axis. However, a structure in which the base frame is omitted and the rotating frame and the cap frame are supported by the bed main body by the guide shaft is also in practical use.

For example, as described in Japanese Patent Application Laid-Open No. 6-257057, the cap frame includes a curved mounting frame portion for mounting on the rotating frame of the cap frame driving unit, and the cap is fitted onto the cap frame. It comprises a cap frame body for setting in a shape, and a holding frame member which is detachably fixed from the outside with the cap sandwiched in the cap frame body. Although there are various shapes of the cap frame body, generally, since the front part of the cap is embroidered and sewn, the opening side annular part of the cap and the expanded sweat removing part are fitted onto the cap frame body. In this case, a structure in which the four outer peripheral sides of the embroidery region of the cap are held by being sandwiched between the cap frame body and the pressing frame member is put into practical use. One end of the pressing frame member is rotatably connected to the cap frame main body by a hinge mechanism, and the other end of the pressing frame member is releasably connected to the cap frame main body by a connecting fitting.

When the hat is attached to the hat frame, it is necessary to attach the cloth member in the embroidery area of the hat in a stretched state without loosening. When attaching the hat, the holding frame member is opened to one end side. In addition, the cap is externally fitted to the cap frame main body, and the pressing frame member is externally fitted to the cap frame main body with the cap sandwiched between the cap frame body and the connecting metal fitting. Conventionally, since the circumferential length of the holding frame member is relatively small because the embroidery is applied only to the front surface of the hat, the holding frame member is pressed while pressing the cloth member of the hat with one end side portion of the holding frame member. At the other end of the above, the connecting metal fitting was fastened while pulling the cloth member of the hat with one hand.

[0006]

In the conventional cap frame, since one end of the pressing frame member is rotatably connected to the cap frame main body by the hinge mechanism, the cap frame member on the hinge mechanism side is sufficient. It is difficult to fix the cloth member by applying sufficient tension, and the cloth member tends to loosen, and in order to adjust the tension of the cloth member, the connection of the connecting metal fittings must be released and the tension condition must be adjusted again. . In particular, recently, there has been a request to embroider both the left and right sides in addition to the front part of the hat. Therefore, when the press frame member is configured to be long in the circumferential direction, the cloth member is attached to the other end side of the press frame member. Even if it is pulled, it is very difficult to apply tension to the cloth member on one end side, and there is a problem that the work efficiency of attaching the hat to the hat frame is reduced. An object of the present invention is to make it easy to attach a hat to a hat frame in a desired state without loosening, and to improve work efficiency when attaching the hat.

[0007]
