Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is intended for embroidering on a peripheral surface of a bag made of thick material such as vinyl or leather, such as a bag-shaped portion in a sports bag or a golf caddy bag. The present invention relates to a holding frame for an embroidery sewing machine.

[Conventional technology]

As shown in Japanese Unexamined Utility Model Publication No. 60-110493, this type of conventional holding frame includes an annular upper frame and a lower frame that are vertically opposed to each other, and the lower frame protrudes from the base frame. The upper frame is fixed to the protruding bar so as to be located above the needle drop position, and the upper frame is fixed to a support fitting protruding from the base frame so as to be vertically movable by a screw mechanism.

[Problems to be solved by the invention]

In the holding frame of the conventional embroidery sewing machine, the screw mechanism is loosened to leave a gap between the upper frame and the lower frame, and the peripheral wall of the bag to be embroidered is inserted into the gap, and then the screw mechanism is tightened to fix the upper frame. Since the bag is pressed against the lower frame and the bag is held between the upper frame and the lower frame, there is a problem that the embroidery pattern may be broken by holding the bag with the bag loose and the needle may be broken. Since the upper frame and the lower frame surround the area above the drop position, there is a problem that the embroidery area is greatly limited by the upper frame and the lower frame.

The present invention has been made in view of the above points, and an object thereof is to hold an area in which a peripheral wall of a bag to be embroidered can be held in a stretched state and embroidery can be performed on the peripheral wall of the bag. An object of the present invention is to provide a holding frame for an embroidery sewing machine which can be greatly expanded.

[Means for solving the problem]

In order to achieve the above object, the present invention employs the means described in the claims, and the operation is as follows.

[Action]

When the opening of the bag to be embroidered is relatively inserted into the two supporting rods so that the rotating rod is outside, and the rotating rod and the supporting rod are relatively rotated in this state, the two supporting rods are rotated. A tensile force can be applied to the peripheral wall of the bag between them to tension the peripheral wall. As a result, embroidery can be performed on the peripheral surface of the bag in a stretched state, and collapse of the embroidery pattern can be prevented.
