Description

[Detailed explanation of the idea] The present invention relates to an improved embroidery hoop.

As shown in FIG. 1, the conventional embroidery frame 1a has a ring-shaped inner frame 2a with a desired height and wall thickness, and a ring-shaped inner frame 2a with the same height and wall thickness as the inner frame 2a. It consists of a ring-shaped outer frame 3a having an inner diameter slightly larger than the outer diameter.

This embroidery frame 1a is used after placing the fabric 4 to be embroidered on the inner frame 2a, fitting the outer frame 3a onto it, stretching the fabric 4, and fixing it to the embroidery frame 1a.

In this case, although it is easy to stretch the fabric 4, there is a drawback that when the thickness of the fabric changes, it is necessary to use an embroidery frame that matches the thickness of the fabric, or to use one with a large outer frame.

In addition, there is also the disadvantage that the stretched fabric 4 gradually loosens during stitching, so the fabric 4 of the frame must be stretched frequently.

An embroidery frame 1b as shown in FIG. 2 is available on the market that eliminates these drawbacks.

In FIG. 2, 2b has a circular inner frame similar to the conventional one, 3b has an inner diameter slightly larger than the outer diameter of the inner frame 2b,
It is an open ring-shaped outer frame which is provided with an adjustment part 7 which is cut at required points and fixed with screwed L-shaped metal fittings 5, 5 on both ends thereof, and further tightened with screws 6.

This embroidery frame 1b is made by fitting the outer frame 3b with the adjustment part 7 loosened onto the inner frame 2b on which the fabric 4 to be embroidered is placed, and then tightening the screws 6 to bring the outer frame 3b into close contact with the inner frame 2b. , the fabric 4 is stretched and fixed to the embroidery frame 1b before being used.

In this case, one embroidery frame 1b is sufficient even if the thickness of the fabric changes considerably, and since the outer frame 3b is tightly tightened to the inner frame 2b, the fabric 4 does not loosen during embroidery. However, there are disadvantages in that the embroidery thread may become entangled with the adjustment section 7 during embroidery and break, and the carrying bag in which the adjustment section 7 is carried may be damaged.

In addition, similar to embroidery frame 1a, the outer frame 3 is
There is also the drawback that the fabric 4 supported by the inner frames 2a, 2b near the inner frames 2a, 2b may be rubbed and soiled.

This invention was developed to eliminate these drawbacks; it is easy to attach the fabric, there is almost no slack in the fabric during embroidery, and the same embroidery hoop can be used even if the thickness of the fabric varies. To provide an embroidery frame that can be used easily, has no metal fittings protruding outside the embroidery frame, and does not stain the fabric near the frame.

In FIG. 3 showing the first embodiment of the present invention, 1 is wood;
An embroidery frame made of bamboo, synthetic resin, etc. or a combination thereof, which has a triangular cross section and a predetermined height on the upper surface of a circular inner frame main body 8 having a desired height and wall thickness. The inner frame 2 has a protrusion 9 and a plurality of notches 10 at predetermined intervals on the lower surface of the inner frame main body 8, and has the same height as the inner frame 2 and the same wall thickness as the inner frame main body 8. , an outer frame 3 having an eave-like locking part 12 that protrudes inward to cover the protrusion 9 at the upper end of an annular outer frame body 11 having an inner diameter slightly larger than the outer diameter of the inner frame 2. Become.

This embroidery frame 1 is constructed by placing the fabric 4 to be embroidered onto the inner frame 2 from the side with the protrusions 9, and then fitting the outer frame 3 onto the inner frame 2 using the locking portions 12 so as to cover the protrusions 9, and then stretching the fabric 4. After it is fixed to the embroidery frame 1, it is used for embroidery.

In this case, the fabric 4 is sandwiched between the outer frame main body 11 and the inner frame main body 8 which has notches 10 and is given elasticity, and is further locked by the projections 9 and the locking parts 12. Therefore, the fabric 4 can be firmly held.

In addition, the part of the fabric 4 that is most likely to get dirty during embroidery, which is locked between the inner frame 2 and the outer frame 3, is covered by the locking part 12 of the outer frame 2 to prevent it from getting dirty.

Furthermore, since there are no metal fittings protruding from the outer frame 3, the embroidery thread will not be cut or tangled.

In FIG. 4 showing the second embodiment of the present invention, 1° is the first
An embroidery hoop made of the same material as in the example.
An inner frame 2 has a protrusion 9° and a notch 10o similar to the first embodiment on the upper surface of a deformed circular inner frame main body 8° having the required height and wall thickness with a corner 13 having a /4 arc.゜, and a deformed circular ring having the same height as the inner frame 2゜, the same wall thickness as the inner frame main body 8゜, and having a predetermined gap with the outer surface of the inner frame 2゜. It consists of an outer frame 3° with an eave-like locking part 12o protruding inwardly so as to cover the protrusion 9° at the upper end of the outer frame main body 11o.

The method of using this 1° embroidery frame is the same as in the first embodiment.

In addition, this embroidery frame 1° has the effect of making it easier to embroider the corner of a handkerchief, the collar of a blouse, etc. by using the corner 13, but there are other effects as well. is the same as in the first embodiment.

In both of the above embodiments, the frame bodies 8, 11 and 8°, 11o of the embroidery and embroidery frames 1 and 1° were formed into a circular ring shape and a modified circular ring shape, but the frame bodies 8, 11 and 8°, 11o has protrusions, notches, and locking portions 9, 10.12, and 9. , 10
．． , 12o, respectively, and the outer frame bodies 11 and 11 . As long as the structure fits externally, the shape is not limited to this shape, and the shape of corners such as triangles, quadrilaterals, and polygons may be a combination of shapes including circles.

Further, although the inner frame bodies 8, 8o are formed in an upright state, the notches 10, 10. If the lower part of the outer frame body 11 is formed to expand outward, the fabric 4 can be held more firmly, and the outer frame bodies 11, 11. Providing a protrusion on the inner lower end of the inner frame body 8 will not only further secure the fabric 4 but also allow the inner frame bodies 8, 8 to
It becomes possible to increase the gap between the outer frame bodies 11 and 11o, and the same embroidery frame can be used even if the thickness of the fabric changes considerably.

Although the protrusions 9 and 9o are continuous, they may be cut to a suitable length or may be arranged in dotted lines.

Since the present invention has the above configuration, it has the following effects.

(1) Regardless of how easy it is to attach the fabric, the fabric is held in place by the locking part of the outer frame, the protrusion of the inner frame, the lower part of the outer frame body, and the notched lower part of the inner frame body, so the fabric cannot be easily attached during embroidery. No slack occurs.

(2) Since the part of the fabric that is most easily soiled during embroidery, which is secured by both frames, is covered by the securing portion, stains during embroidery can be kept to a minimum.

(3) By opening the lower part of the inner frame body outward, the locking force of the fabric increases and the gap between the inner frame body and the outer frame body can be increased, so the thickness of the fabric You can embroider with one embroidery hoop even if the pattern changes considerably.

(4) Although it has excellent functions, it has a simple structure and is easy to manufacture, so it can be provided at low cost.
