Japanese Patent No. 2583095

As for the embroidery place on the peripheral wall 80a of the hat, as shown in FIG. 10 (see Patent Document 1), there is a demand for embroidery in various places such as the front face 82a, the front side face 82b, the side face 82c, and the rear side face 82d.
In this conventional embroidery machine curved cloth tension frame, when there is a demand for a wide range of embroidery on the side surface 82b of the hooked cap 80, the fastening means E is taken out as shown in FIG. Since the collar 87d is secured to the rear side 6 of the base frame B and is taken out toward the tip of the receiving frame D, the hat collar 81 hits the carry-out collar 87d, and the needle embroidery area 82b is dropped. There is a problem in that it cannot be positioned above the position and cannot meet the embroidery request for the side surface 82b of the hat peripheral wall 80a.

Furthermore, when embroidering the side face 82c of the hat with a hook, when the hat 80 is put on the receiving frame C and attached, the operator holds the hat hook 81 with one hand and the hat peripheral surface 80a with the other hand. Then put the cap on the receiving frame C. After that, the heel 81 is bent and inserted into the gap 91 between the base portion of the carry-out heel 87d and the base frame B, and the embroidery scheduled area 82c on the side of the hat must be positioned above the needle drop position. In addition, the carry-out rod 87d is in the way, and there is a problem that it takes time and labor to put on the hat 80.
Further, as shown in FIG. 10B (see Patent Document 1), there is an example in which the take-out rod 87d in the fastening means E is configured to project in a U shape and the rod 81 is placed in the gap 91d. It is disclosed. However, in such a embroidery sewing curved cloth tension frame, the presser frame D is fastened to the receiving frame C using the fastening means E, and the periphery of the embroidery planned area of the hat 80 is fixed to the receiving frame C. In the case of mounting in the tensioned state, the base portion of the take-out rod 87d in the fastening means E is firmly fixed to the fastening body 88d, and the distance to the fastening member 89d that holds the fastening means E is taken out long. Therefore, the presser frame D is weak against the tightening force for pressing and pressing the presser frame D against the receiving frame C, and the presser frame D cannot be fastened to the receiving frame C with a strong force. This means that during the embroidery sewing, the cap may be displaced with respect to the receiving frame C and the embroidery pattern may be displaced. Furthermore, when the hat collar 81 is intended for a very long object, the U-shape of the carry-out collar 87d becomes larger and weakens against bending force.
Therefore, it is conceivable to widen the carry-out bag 87d and make it strong, but then the fastening body 88d that supports the carry-out bag 87d also becomes large, and when the carry-out bag 87d becomes wide, The degree of obstruction when mounting is increased, and there is a problem that workability is deteriorated.

The purpose of this application is to embroider the front embroidery area on the hat perimeter wall as well as to embroidery in the same manner as before, but also to embroider the side embroidered area on the side of the hat perimeter wall with a collar. An object of the present invention is to provide a curved embroidery frame for an embroidery sewing machine which can be embroidered on a side face of a hat by mounting a planned embroidery area on a receiving frame, and which can respond to various embroidery demands at various locations on the peripheral wall of the hat.
Another object of the present invention is to provide a embroidery sewing bend frame that can be quickly positioned when the cap is mounted on the receiving frame when embroidering the embroidery scheduled area on the side surface of the hat with a hook.
Furthermore, an object of the present invention is to provide an embroidery sewing curved cloth tension frame that can be attached to an embroidery sewing curved cloth tension frame even if the hat has a long heel length.
The other purpose is that it can withstand even if the presser frame connected to the fastening means is tightened with a strong force, and eventually the presser frame can be pressed and pressed against the receiving frame with a strong force, and the planned embroidery area is pulled. An object of the present invention is to provide a bent frame for an embroidery sewing machine that can be held in a high-quality state and can provide a high quality embroidery product.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.
