Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a embroidery frame, and more particularly to a embroidery frame that is provided with a plurality of attachment pieces and has an enlarged embroidery area.

The instruction signal from the sewing data memory 1 is input to the arithmetic circuit 3 via the signal conversion processing circuit 2, and the data signal from the arithmetic circuit 3 is supplied to the sewing machine motor drive circuit 4 and the servo motor drive circuit 5. Drive control of the sewing machine motor 6, Y-axis servo motor 7, and At the same time, the needle 12 is moved up and down to complete a predetermined pricking operation.

Therefore, the stabbing area is determined by the predetermined movement of the traveler 11 in the X-axis direction due to the movement of the traveler 11 in the Y-axis direction and the movement of the Y-axis guide rod 13 in all directions of the X-axis.

The conventional embroidery frame 9 has a circular shape as shown in FIG. is based on the traveler's predetermined movement area mentioned above.
Therefore, it is impossible to enlarge the embroidered castle beyond this circular part, and the size of the design is inevitably limited. The present invention has focused on the above-mentioned points, and an object of the present invention is to provide an embroidery frame that allows large patterns to be embroidered without removing the embroidery frame from the traveler.

According to this invention, a plurality of spaced apart mounting pieces are provided on the outer frame of the stabbing frame, and one of the mounting pieces is removably fixed to the traveler of the stabbing frame, and the other mounting piece is detachably attached to the traveler of the stabbing frame. A embroidery frame is provided which is characterized in that the embroidery frame can be expanded by changing the embroidery frame to a freely fixed position. FIG. 2 shows an embodiment of the present invention.

The embroidery frame 13 has an outer frame 14 and an inner frame 15 that is fitted into the inner peripheral surface of the outer frame 14, and the fabric to be embroidered is placed between the outer frame 14 and the inner frame 15. and tension the fabric without sagging.

First and second attachment pieces 16 and 17 are provided on the outer peripheral surface of the outer frame 14 to be detachably fixed to the traveler 11. Two mounting pieces 16 and 17 are provided spaced apart from each other. Stitch frame 13
connects the semicircular portion 18 with the semicircular portion 18 having a center line of curvature on the longitudinal center line of the attachment pieces 16, 17. Preferably, the intermediate portion 19 has a circular arc shape. The first mounting piece 16 is fixed to the traveler 11, and the sewing machine motor and the servo motors 7, 8 are operated according to the data signal from the arithmetic circuit 3.
is driven to make a predetermined pattern of stitches in area 1.

When the stitching of area 1 is completed, the stitching data memory 1 is transferred to the sewing machine motor drive circuit 4 and the display tube drive circuit 20 via the signal conversion processing circuit 2 and the arithmetic circuit 3.
This data signal is supplied, and the sewing machine motor 6 is stopped and the mounting piece number is indicated on the display tube 21. In this example, the second display is made and the second attachment piece 17 is fixed to the traveler 11. Next, the stitching in area 0 is carried out by turning on the start switch 28 in accordance with the instruction signal from the stitching data memory 1. As is clear from the above, by making it possible to stitch into areas 1 and 0, it becomes possible to stitch a pattern that is twice the size of the conventional pattern.

FIG. 4 shows another embodiment of the invention.

In this example, the first and second mounting pieces 17', 1
It has third and fourth mounting pieces 22, 23 facing 8'. The embroidery frame 13' preferably connects circular parts 24, 24' having centers of curvature on a line connecting the centers of the first and fourth attachment pieces 17', 23, and the circular parts 24, 24'. includes an intermediate portion 26 formed in an arc shape, circular portions 26, 26' having their centers of curvature on the center lines of the second and third mounting pieces 18', 22, and the circular portion 2.
6, 26', preferably a connecting part 2 that connects the intermediate part 25' formed in a circular arc shape and the circular parts 24, 26.
7 and a connecting portion 27' connecting the circular portions 24' and 26'. In this example as well, similarly to the example shown in FIG.
The sewing machine motor 6 and servo motors 7 and 8 are controlled in accordance with the data signal from the arithmetic circuit 3 to stitch a predetermined pattern in the area 1.

Upon completion of stitching in area 1, the arithmetic circuit 3 instructs the number of the next attachment piece and instructs the sewing machine motor 6 to stop. By attaching the specified attachment piece to the traveler 11 and turning on the start switch 28, stabbing is performed in the specified area. Sequentially, a pricking frame is formed in the specified area, and finally it becomes possible to stab in all areas 1 to W, and the stabbing range expands. As is clear from the above, a plurality of mounting pieces are provided on the stitching frame, and the display tube drive circuit connected to the output terminal of the computing circuit receives an output from the computing circuit in response to an instruction signal from the stitching data memory. By sending data signals, configuring the mounting frame instructions on the display tube, and converting the attachment piece, you can change the stitching force and expand the stitching range.
