DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hat frame for a sewing machine, and more particularly to a hat frame which can be easily attached to a hat frame in a desired state without loosening.

[0002]

2. Description of the Related Art Conventionally, in a multi-needle 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 (the arm portion of the embroidery sewing machine). Embroidery sewing is performed in a state where the embroidery sewing machine is attached to a movable frame that is driven independently of the embroidery direction. By the way, in order to embroider sewing on the front of the hat, a hat frame device connected to an X-axis drive mechanism and a Y-axis drive mechanism of an embroidery sewing machine is used.

[0003] This hat frame device comprises a hat frame drive unit and a hat frame detachably attached to the hat frame drive unit with the hat mounted. The hat frame driving unit generally includes a base frame that is driven in the Y-axis direction, and a rotation frame that is rotatably supported by the base frame and is driven to rotate around an axis parallel to the Y axis. However, a structure in which the base frame is omitted and the rotating frame and the hat frame are supported on the bed body by the guide shaft has been put to practical use.

[0004] For example, as described in Japanese Patent Application Laid-Open No. 6-2557057, the cap frame includes a curved mounting frame for mounting on a rotating frame of a cap frame driving unit, and the cap is fitted over the cap frame. A hat frame body for setting in a shape, and a holding frame member which is detachably fixed from the outside with a hat sandwiched between the hat frame body. There are various shapes of the hat frame main body, but generally, since an embroidery sewing is performed on a front portion of the hat, the opening side annular portion of the hat and the expanded sweat absorbing portion are externally fitted to the hat frame main body. Practically, a structure in which the four sides on the outer peripheral side of the embroidery area of the hat are held in a state of being sandwiched between the hat frame body and the holding frame member has been put to practical use. One end of the holding frame member is rotatably connected to the hat frame main body by a hinge mechanism, and the other end of the holding frame member is connected to the hat frame main body by a connection fitting so as to be freely released.

When attaching a hat to the hat frame, it is necessary to attach the cloth member in the embroidery area of the hat in a stretched state. When attaching the hat, the holding frame member is opened to one end. In advance, the cap is externally fitted to the cap frame main body, and the holding frame member is externally fitted to the cap frame main body with the cap interposed therebetween to fasten the connection fitting. Conventionally, since the circumferential length of the holding frame member was relatively small because the embroidery was performed only on the front portion of the hat, the holding frame member was pressed with the cloth member of the hat at one end of the holding frame member. At the other end of the hat, the connecting member is fastened while pulling the cloth member of the hat with one hand.

[0006]

In the conventional hat frame, one end of the holding frame member is rotatably connected to the hat frame main body by a hinge mechanism, so that it is sufficient for the cloth member of the hat on the hinge mechanism side. It is difficult to fix the fabric member by applying appropriate tension, and the cloth member tends to loosen. In order to adjust the tension state of the cloth member, it is necessary to release the connection of the connecting bracket and adjust the tension state again. . In particular, recently, there has been a demand for embroidering on both the left and right sides in addition to the front part of the hat. Therefore, when the holding frame member is configured to be long in the circumferential direction, the cloth member is provided on the other end side of the holding frame member. Even if it is pulled, it is very difficult to give 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 easier to attach a hat to a hat frame in an intended state without loosening, and to improve work efficiency when attaching the hat.
