Description

[Detailed explanation of the idea] The present invention relates to a embroidery frame.

Conventionally, in order to hold the fabric between the outer frame and the inner frame of the embroidery frame, a notch has been formed in the inner frame to provide a resilient force, but stress concentration occurs in the notch, and In addition, because the cylindrical part of the inner frame is shortened by the notch, in other words, it is deeply cut in order to obtain elasticity, so it easily breaks from the notch and cannot withstand long-term use. .

In addition, the holding power of the fabric for stitching was weak and it loosened during stitching, making it difficult to stitch and had to be re-strung many times.

The present invention eliminates these drawbacks, and the inner frame body has a double structure of an inner cylinder part and an outer cylinder part, so
Even if stress concentration occurs at the notch, it will not break easily, so it can be used for a long time.It also has strong elasticity and holds the fabric firmly, so it will not break easily during stitching. To provide a embroidery frame that does not cause loosening of fabric.

Therefore, the feature of the present invention is that the inner frame body of the elastically deformable member is formed into a substantially inverted U-shape with a short cylindrical shape and a bent longitudinal section, forming an outer cylindrical part and an inner cylindrical part.
At least a plurality of notches are formed at predetermined intervals in the outer cylinder part, and the outer frame main body has a short, generally cylindrical shape and fits onto the inner frame main body.

The following description will be made based on the illustrated embodiments.

Reference numeral 1 denotes an outer frame body, and the outer frame body 1 is made of synthetic resin or wood, and has a short cylindrical shape, and has an eave-shaped fixing part 2 around it that protrudes from the inner upper periphery of the outer frame body 1 toward the center. ing.

Reference numeral 3 denotes an inner frame body, and the inner frame body 3 has an inverted U-shape with a short cylindrical shape and a bent vertical section, and an outer cylinder part 4.
and an inner cylindrical portion 5. and the outer cylinder part 4
A notch 6 shown in FIG. 3 near the upper end of the
The cut portions 6 are formed at predetermined intervals around the outer cylindrical portion 4, and in FIG. 1, twelve cut portions 6 are provided.

Further, the outer cylindrical portion 4 of the inner frame body 3 is formed to have a bulge in the outer circumferential direction, thereby providing a strong elastic force when fitted into the outer frame body 1.

Therefore, when using the product of the present invention, the inner frame body 3
The outer frame main body 1 is fitted onto the outer frame main body 1. First, the embroidery fabric 7 is placed on the inner frame main body 3, and the outer frame main body 1 is fitted onto the inner frame main body 3 until it reaches the eave-shaped fixing part 2.
The fabric is pressed against the fixing part 2 by the inner frame body 3, and the fabric is elastically urged inside the outer tube body 1 by the outer cylinder part 4 of the inner frame body 3.

Since the fabric is held by the elastic force, the fabric is stretched over the embroidery frame without loosening.

In addition, since the inner frame body 3 is formed of a double structure of the inner cylinder part 4 and the outer cylinder part 5 with an inverted U-shape in longitudinal section, the elastic force increases and Since the inner cylindrical portion 4 is formed and wide, the inner frame main body 3 is formed that does not easily break even if an excessive external force is applied and stress concentration occurs in the cut portion 6.

As shown in FIG. 4, the upper end of the notch 6 of the inner frame main body 3 is formed into a circular shape to form a circular notch end portion 6a, and the external force is dispersed by the circular notch 6a. It may also be designed to deal with damage due to stress concentration.

It is also preferable that the vertical section of the inner frame main body 3 shown in FIG. 5 is made thicker only in the upper part, that is, in the upper part than the notch part 6, so as to particularly cope with damage caused by stress concentration.

Furthermore, the notch 6 shown in FIG. It is also preferable to implement the above embodiments with mutual changes.

The present invention effectively achieves the intended purpose with the above-mentioned configuration, and in particular, the inner frame main body 3 is formed into a substantially inverted U-shape with a bent longitudinal section, and the outer cylindrical portion 4 and the inner cylindrical portion 5, and a plurality of notches 6 are formed at predetermined intervals in the outer cylinder part 4, so that even if stress concentration occurs, the inner frame body 3 will not overlap the outer cylinder part 4 and the inner cylinder part 5. Due to its structure, it does not break easily and can be used for a long time.

In addition, the double structure has a strong elasticity and strongly holds the fabric for stitching, so the fabric does not loosen during stitching. Therefore, the present invention has significant effects.
