Description

DETAILED DESCRIPTION OF THE INVENTION The invention of this application relates to a frame used to form seams in tubular fabric. In particular, the present invention relates to the structure of a frame that allows sewing on fabrics such as socks using a sewing machine.

An example of conventional embroidery stitching on cylindrical fabrics, such as socks, using a sewing machine is to clamp the fabric between an outer frame and an inner frame of a certain shape and stretch it. A frame configured to perform machine stitching is used. In this case, for example, after embroidering only one side of the fabric such as socks, in order to embroidery another side, remove the embroidered fabric from the frame, change its position, and return it to the outer frame. Since the fabric must be stretched between the inner frames and then sewn using a sewing machine, it is complicated and inconvenient to attach and detach the fabric from the frame.

To give another example, for example, in the case of sock stitching, there is a structure in which a plurality of needles are embedded so as to protrude toward the outside of one side of a rectangular rectangular frame.
This frame is inserted into a cylindrical fabric made by spreading and stretching a sock, etc., and the fabric is pierced by the plurality of needles, and the fabric is spread out so that it becomes a flat surface. However, the process of unrolling a tubular piece of fabric and attaching it to a frame with needles embedded in it is extremely dangerous.

Therefore, the invention of the present application has been devised to eliminate the above-mentioned defects, and there is no danger in the work of attaching the fabric to the frame, and once the attachment is completed, the position of the frame can be adjusted without having to attach or detach the frame midway. To provide a frame that enables machine sewing on both sides of a cylindrical fabric by simply changing the frame.

Its structure consists of a rectangular body with frame pillars, etc., a embroidery frame body for covering the cylindrical fabric, and a tube that is covered by engaging with the embroidery frame from both sides of the main body. It consists of a pair of clamping frames that can be opened and closed and that can clamp the shaped fabric between the frame columns so as to spread it out.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

The present invention consists of a embroidery frame main body a on which a cylindrical fabric is spread and covered, and a frame b that can be opened and closed to hold the cylindrical fabric covered over the main body.

One end of the stabbing frame main body a is attached in parallel to the mounting base 2, and has two pairs of frame posts 4a, 4b and 4c, 4d with top circular arc parts 6a, 6b,
The pair of frame columns 4a, 4b and the pair of frame columns 4c, 4d
are the connecting members 8a and 8b that are orthogonal to each other, and the frame pillars 4
a and 4d, 4b and 4c are connecting members 10, respectively.
a and 10b are connected. The connecting members 8a and 8
b, 10a and 10b each have the same length. Reference numeral 12 indicates a hole provided in the mounting base 2.

One of the pair of clamping frames b that can be opened and closed is a frame post 4a,
A member 18 having a U-shaped cross section, which is attached to the mounting base 2 on the side to which the 4b is attached, via a hinge 14 so as to be openable and closable, and whose end portion is integrated with a connecting portion 16 having a U-shaped cross section;
20, and the other pair is attached to the mounting base 2 on the side where the frame columns 4c and 4d are mounted so as to be openable and closable via a hinge 22, and a connecting portion 2 having a U-shaped cross section is attached to the other end.
It consists of members 26 and 28 that are U-shaped in cross section and are integrally formed. A key-shaped locking member 30 is attached to the upper surface of the U-shaped portion at approximately the center of the U-shaped connecting portions 16 and 24 of the U-shaped members 18, 20 and 26, 28 connected to the hinges 14 and 22, respectively. , 32 are fixed. Reference numeral 34 is a permanent magnet piece provided on the mounting base.

Next, the operation of this embodiment will be described. First, a cylindrical cloth such as a sock α is placed over the embroidery frame body a as shown in FIG. 3. The opening of the sock α opens toward the mounting base 2 and covers the frame body a. Hinge 14, 2 in which members 20, 18 and 26, 28 each having a U-shaped cross section are attached to mounting base 2 so as to be openable and closable.
2 in the direction of arrow E, that is, toward the frame body a, the U-shaped recesses of the U-shaped members 20, 18 connect the frame columns 4a, 4b, and the U-shaped recesses of the connecting portions 16 connect the frame columns 4a, 4b. The connecting members 8a of 4b are sandwiched and crimped to each other. The cylindrical body fabric α is in contact with the outer periphery of the frame columns 4a, 4b and the connecting member 8a.
(See figure) At the same time, the U-shaped member 26 of the clamping frame b is attached to the mounting base via a hinge 22 so as to be openable and closable.
28, U-shaped connecting portion 24 is made of cylindrical body fabric α
This is secured around the frame pillars and the connecting member so as to surround the frame pillars 4c, 4d and the connecting member 8b. On the other hand, the locking members 30 and 32 attached to the upper surface of the connecting member 16 and the U-shaped connecting portion 24 are secured to the outer peripheries of the frame column top circular arc portions 6a and 6b, so that the clamping frame b is prevented from moving. The cylindrical fabric α is attached to the embroidery frame main body a, and the frame posts 4a, 4b and 4c, 4d
It is spread out almost horizontally between the two.

However, the stitches to be embroidered are first made on the frame posts 4a and 4b.
The cylindrical fabric α'' is formed on the side of the cylindrical fabric α′ held between them by one of the pair of clamping frames, and then the cylindrical fabric α″ is held between 4c and 4d with the position reversed.
With the upper surface facing α'', a stitch can be similarly formed on the upper side α″.

In the present invention, as described above, when the cylindrical body α is immovably held by the clamping frame b on the embroidery frame main body and the cylindrical body α is to be sewn on both sides of the cylindrical body α, the cylindrical body is removed. By rotating the cylindrical body fabric at an appropriate angle, for example 380 degrees, and changing its position while the cylindrical fabric is attached without having to go through the trouble of re-attaching it, it is possible to easily embroidery and sew on both sides. effective.

Furthermore, safety is ensured compared to the dangerous and inefficient pricking frame with embedded needles as in the past, and the stabilizing frame main body a is held by the clamping frame b to prevent it from falling through the cylindrical fabric. Since it securely clamps, it also has the effect of accurately forming various beautiful embroidery stitches.

In this embodiment, the top arc portions 6a, 6b
are formed integrally with the frame columns 4a, 4b, 4c, and 4d, but by eliminating the apex arc portion, the frame columns 4a,
4b, 4c, 4d may be provided protrudingly, or the U-shaped members 18, 20, 2 of the clamping frame b may be provided.
Without providing the locking members 30, 32 on the upper surfaces of the U-shaped connecting portions 16, 24 of 6, 28, the members 18, 20, 26, 28 having a U-shaped cross section and the U-shaped connecting portion 1
We devised the shape, width, etc. of each of 6 and 24,
Of course, by providing hooks on the U-shaped connecting portions 16 and 24 and hooking these hooks on the connecting members 8a and 8b, the cylindrical fabric α can be reliably locked to the outer periphery of the frame column.
