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 for pressing a thin presser frame portion for pressing an outer surface of a base of a hat eaves so as not to be displaced.

[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 hat frame includes a curved mounting frame portion for mounting to a rotating frame of a hat frame driving section, and the opening side of the hat. The hat frame body includes a cap frame body for setting the annular portion so as to be fitted to the outside, and a pressing frame member detachably fixed to the cap frame body from outside with the cap interposed therebetween. There are various shapes of the hat frame body, but since the embroidery sewing is performed on at least the front part of the hat, the opening-side annular portion of the hat and the sweat-absorbing portion inside the hat-side portion, and the sweat-absorbing portion developed to the outside. The outer peripheral side of the hat embroidery area can be supported, and the outer peripheral four sides of the embroidery area of the hat can be supported. The pressing frame member can hold the outer peripheral four sides of the embroidery area of the hat with the cap sandwiched from outside the hat frame main body. It is configured as follows.

In recent years, there has been a demand for embroidering on the left and right side portions in addition to the front portion of the hat. In this case, a hat frame having a structure for holding four sides on the outer peripheral side of the embroidery area of the hat is adopted. It is difficult to do so, holding the opening side annular part of the hat and the sweat-absorbing part expanded outward with the hat frame, letting any shape retaining member of the hat frame enter the inside of the hat, and loosening the cloth member in the embroidery area of the hat It is necessary to pinch and fix the portion near the base end of the eaves in the opening side annular portion of the hat between the hat frame main body and the eaves outer holding frame portion of the holding frame member in order to stretch the hat. . The outer holding frame portion of the eave of the holding frame member has a narrow width and poor rigidity so as not to protrude from the outer surface of the base end portion of the eave into the embroidery area.

[0006]

As described above, in the case of a hat frame in which embroidery can be applied to the front portion and the left and right side surfaces of the hat as described above, the eaves outer holding frame portion of the holding frame member is located at the outer edge of the embroidery area. And the inner side is supported by the hat frame body,
Since the area near the inner side of the eaves outer holding frame opposite to the eaves side is not supported by the hat frame body, the hat cloth member is directed outward in the area where the base end of the eaves overlaps the seam of the hat. Because the cloth member of the hat is easily swelled and the cloth member of the hat is pulled forward by the shape retaining member, the outer holding frame portion of the eaves can easily escape in a direction opposite to the eaves (the embroidery area side).

Therefore, the work efficiency of the work of setting the hat on the hat frame is reduced, and if the eaves outer pressing frame moves in the direction opposite to the eaves during embroidery sewing, it interferes with the sewing needle and the sewing needle is damaged. If there is a danger that the eaves outer holding frame portion is allowed to move in the opposite direction to the eaves or the width of the eaves outer holding frame portion is made larger, the embroidery area in front of the hat becomes narrower,
There are problems such as. SUMMARY OF THE INVENTION An object of the present invention is to provide a hat frame for a sewing machine that can surely prevent the eaves outer pressing frame portion from moving toward the embroidery area.
