DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery frame which stretches and holds a fabric or the like in order to perform embroidery with a good finish.

[0002]

2. Description of the Related Art An embroidery sewing machine having multiple heads can embroider the same pattern on a plurality of fabrics at the same time. In this case, in order to prevent wrinkles and slippage and improve the finish, the individual fabrics are stretched and held in a state as uniform as possible. For this reason, the fabric is attached to the embroidery frame and set on the embroidery sewing machine via the embroidery frame. Conventionally, the embroidery frame for that is a form in which the cloth is sandwiched by a fitting-type frame in which two large and small rings are set (ring type)
And a form (plate type) in which a cloth is attached with an adhesive to a plate-like frame in which a cutout window is formed along an embroidery pattern is known.

[0003]

The ring type frame is
The small ring is pressed into the large ring in order to maintain a sufficient expansion state, but the pressure must be adjusted according to the thickness.If it is too tight, it will be difficult to fit thick cloth, and paper etc. Thinner ones tend to have frame marks and scratches on the fabric. Conversely, if the pressure is reduced in order to avoid these problems, uniform stretching cannot be maintained, and wrinkles and deviations occur during embroidery. In addition, a material such as vinyl that easily expands and contracts even if a large pressure is applied, and a uniform state of expansion cannot be obtained. When it is not possible to use the ring type, use the plate type, but the work of applying the adhesive is troublesome, the adhesive does not work,
It remains and cannot be removed. An object of the present invention is to solve the above-mentioned drawbacks in an embroidery frame, to make it easy to work, and to make it possible to uniformly stretch and hold cloths and the like that could not be stretched and held by a conventional embroidery frame.

[0004]

The invention according to claim 1 of the present invention comprises a large-diameter ring and a small-diameter ring that can be fitted so that their peripheral wall surfaces overlap each other, and a sheet is sandwiched between the two to extend the sheet. In the embroidery frame to be held, a magnetic force capable of maintaining the sheet stretched is provided between mutually facing surfaces of the large-diameter ring and the small-diameter ring. Here, the sheet refers to (combination of) any planar material on which embroidery can be performed, and examples thereof include cloth, vinyl, paper, non-woven cloth, and cloth applied with paper.

According to a second aspect of the present invention, in the first aspect of the present invention, both the large and small rings are formed with flanges having surfaces facing each other in a fitted state, and the mutually facing surfaces of the flanges are formed. That is, a magnetic force is applied between them.

According to a third aspect of the present invention, there is provided an embroidery frame comprising a film-like plate capable of cutting out an arbitrary shape, and holding the sheet in close contact with the plate by stretching the plate. The present invention is characterized in that a magnetic force capable of maintaining the spread of the sheet is provided between the plate and the pressing member in combination with the pressing member arranged in close contact.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a head 2
FIG. 6 is an explanatory view of an embroidery sewing machine 1 provided with six embroidery frames, wherein a multi-core needle 3 is provided on the lower surface of each head 2, and an embroidery frame is arranged so that the cloth C is positioned in an extended state below each multi-core needle 3. 10 are set on the underframe 5 of the table 4, respectively.

FIG. 3 is an explanatory view of the embroidery frame 10 of the ring type. The embroidery frame 10 includes a small-diameter ring 11 and a large-diameter ring 12 into which the small-diameter ring 11 is fitted.
a. The threaded portion 12a cuts the large-diameter ring in the radial direction, cuts holes opposite to each other at both cut portions, and straddles the screw, thereby enabling the gap between both cut portions to be adjustable by rotation of the screw. , In a connected state. In addition, flanges 11b,
12b is provided so as to overlap when the ring is fitted. Conversely, the side peripheral portions facing each other are slightly loosely fitted. Each of the flanges 11b, 12b has bar-shaped magnets 14, 14,... Buried at predetermined intervals at positions corresponding to the ring-fitted state with opposite poles facing each other.

FIG. 4 is an explanatory view in the case where the cloth C as a sheet is stretched and held by using the embroidery frame 10, and FIG.
FIG. 3 is an explanatory view showing a part of a vertical end face. Between the mutually facing surfaces of the flanges 11b, 12b, the surface of the magnet 14 embedded in the flange 11b and the surface of the magnet 14 embedded in the flange 12b corresponding to the magnet are opposed to each other with different polarities. The layers of C are superimposed while generating a magnetic force that can be maintained. The dough C is passed between the slightly loose, opposed ring-side peripheral surfaces and clamped between the flanges as described above.

Since the embroidery frame 10 applies a magnetic force between the flanges, the embroidery frame 10 can be easily attached and detached, the fabric can be easily set, and the operation feeling is excellent. Moreover, important points can be firmly fixed irrespective of the thickness and properties of the cloth C, and therefore, a uniform and favorable expanded state can be maintained. Furthermore, since the opposed ring-side peripheral surfaces are loosely fitted while the flanges are overlapped by applying a magnetic force to the flanges, thin fabrics and vinyls, which can not be embroidered by an embroidery sewing machine with a conventional ring type frame, are easily stretched. Nonwoven fabrics can be set with minimum occurrence of slip, scratches, frame marks, pulling unevenness, etc., and embroidery can be performed by attaching to an embroidery sewing machine. The loose fitting state (pressure) at each ring side peripheral portion can be adjusted by the screw portion 12a.

FIG. 6 is an explanatory view of the embroidery frame 20 of the plate type, which is suitably used when embroidering the same pattern on one piece of cloth B by the embroidery sewing machine 6 as shown in FIG. The embroidery frame 20 is composed of a rubber magnet 21 as a thin plate that does not exhibit the elasticity of a substantially cloth B and a plurality of rod-shaped magnets 2.

The embroidery frame 20, as shown in FIG.
Mold 23 with holes slightly larger than the embroidery profile to be applied
With a knife K, holes 21a, 21a,... Matching the positions of embroidery to be applied to the rubber magnet 21 are previously opened. Thereafter, as shown in FIG. 6B, the mold 23 is removed, and the cloth B is placed on the upper surface of the rubber magnet 21. Then, FIG.
As shown in (1), the magnets 22, 22,... Are placed around the hole 21a on the upper surface of the cloth B so that the magnetic force is generated around the hole 21a by extending the cloth B to match the embroidery position with the hole 21a. When wrinkles or misalignments occur, they are corrected, set on the embroidery sewing machine 6 (FIG. 2), and embroidery is performed. As shown in FIG. 6D, when the embroidery S is performed, the rubber magnet 21, the magnets 22, 22,. And the embroidery on the fabric B is completed.

The embroidery frame 20, like the embroidery frame 10, maintains the expanded state of the fabric B by magnetic force, so that the embroidery frame 20 is easy to operate, for example, the frame can be easily attached and detached and the fabric B can be easily modified. , Furthermore, since it is possible to use various forms of magnets,
It can be adjusted so that it is fitted with the optimal tension for the material of the fabric B. And since no adhesive is used, the troublesome application and removal of the adhesive can be omitted, and the finish can be improved.
Embroidery can be applied even to fabrics that cannot be removed or acted upon. In addition, the plate type has a wide magnetic force generating portion, and thus is particularly effective for fabrics that are extremely slippery, and can embroider with an embroidery sewing machine. Needless to say, no frame marks, scratches, shifts, wrinkles, etc. are generated in the above.

The embodiment of the embroidery frame is not limited to the above, and has various modifications as partially shown below. In the embroidery frame 10, as shown in FIG. 7, a magnet may be buried without providing a flange, with a different pole facing the opposite peripheral surface on the ring side. In addition, one of the rings or the magnet may be made of a magnetic metal, a rubber magnet may be stretched around, or the ring may be made of a rubber magnet.
Pressing between the rings may be used in combination with the magnetic force to maintain the expanded state. In addition, the frame can be of various shapes, such as circular, oval, rectangular, and the like. And set to embroidery sewing machine,
It may be through an underframe or a receiving stand. In the embroidery frame 20, a rubber magnet 25 may be used instead of the magnets 22, 22,... As shown in FIG. Further, as a substitute for the rubber magnet, a metal plate or a plastic plate mixed with metal can be used. The dough may be overlaid with paper to spread it to prevent expansion and contraction.

[0015]

According to the embroidery frame of the first aspect of the present invention, since the magnetic force is used to keep the cloth in the expanded state, the ring can be easily attached and detached and the operation feeling is excellent.
In addition, since it is possible to realize the superposition in which the important points are fixed, it is possible to prevent the frame marks, scratches, slippage, wrinkles, deviations, etc. of the sheet.
