In the elastic linkage mechanism 36, when the upper frame main body portion 3b is in the state shown in FIG. 4A (for example, it is lifted from the lower frame main body portion 2b to the position shown in the figure by a spring having a weak force not shown). When holding or being lifted by hand), the presser frame portion 3a hangs down with respect to the upper frame main body portion 3b due to its own weight. Therefore, the guide shaft 43 is located above the long hole 39.
Next, when the upper frame main body portion 3b or the presser frame portion 3a is pushed down to the state shown in FIG. 4B by hand, the presser member 25 of the presser frame portion 3a is parallel to the cloth S on the upper surface of the receiving member 10. And hit evenly. Further, when the upper frame main body portion 3b is pushed down, the base portion 52 is further slightly lowered while the height of the contact piece 51 of the leaf spring 50 is kept as it is, and an elastic force is applied to the holding member 25, and the elastic force downwards. Press. By these operations, an engagement mechanism 53 described later functions in an interlocking manner to lock (maintain) the lowered state of the upper frame main body 3b.

Next, between the lower frame 2 and the upper frame 3, the periphery of the embroidery region A of the cylindrical body S such as a sleeve to be placed on the upper surface of the receiving member 10 of the lower frame 2 is Engaging mechanisms 53 that can be loosened in order to maintain the state of being pressed and fixed by the pressing member 25 are provided at the left and right target positions, respectively. The configuration of the engagement mechanism 53 may be as shown in FIG. 9, but may be configured as follows.

The movable engagement member 54 has a pivot shaft provided upright on the upper surface 2e of the lower frame main body 2b of the lower frame 2, and a pivot portion (hole) 54a provided at one end of itself with respect to the pivot shaft. The other end engaging portion 55 is located at the engagement position (position of FIG. 2 (A)) and the retracted position (position of FIG. 8 (B)). , The position moved from the position in FIG. 2A to the upper position in the drawing).
In the engaging portion 55, as shown in FIG. 8, the upper end of the free end is inclined to form a guiding portion 56, and a concave locking portion 57 is provided at the lower end of the free end.
Further, the movable engagement member 54 is normally biased by using a winding spring 60 in one direction so as to stop at the engagement position.
Further, an operation piece 58 that is connected to the movable engagement member 54 via a connector 59 and moves the movable engagement member 54 to the retracted position is provided at a side position of the lower frame main body 2b in FIG. As shown, it is provided in a protruding shape.

On the other hand, on the lower surface 3e of the upper frame main body portion 3b of the upper frame 3, a fixed engagement member 61 having a locking claw 62 for engaging with the concave locking portion 57 at the free end is fixed. The base portion of the combined member 61 is provided in a state of being fixed (fixed portion 61a) to the lower surface 3e.
The position of the locking claw 62 is such that the locking claw 62 moves as shown in FIGS. 7 (A), 8 (A), and 8 (B) in the process of moving the presser member 25 toward the receiving member 10 (downward movement). The movable engagement member 54 is moved in the retracted position by coming into contact with the guide portion 56, and then the locking claw 62 is moved to the concave locking portion 57 as shown in FIGS. 7B and 8C. Correspondingly arranged to engage.
According to the above configuration, the pressing member 25 of the upper frame 3 is moved downward from above the embroidery region of the tubular body S such as a sleeve to be placed on the upper surface of the receiving member 10 of the lower frame 2 (FIG. 4 ( In the process of moving from the position A) to the position shown in FIGS. 4B and 4C, the engaging portion 55 operates as shown in FIGS. 7 and 8 as the fixed engaging member 61 is lowered. And the positional relationship of the presser member 25 with respect to the receiving member 10 is maintained.

The case where embroidery is performed on the embroidery region A of the tubular body S such as a sleeve using the embroidery frame 1 having the above-described configuration will be described. In addition, the cylindrical body S in FIG. 1 illustrates the sleeve of a shirt. S1 is a cuff and is rubber knitted. S2 shows a cloth-like part.
As shown in FIGS. 1 and 4A, the embroidery frame 1 puts the position of the presser member 25 with respect to the receiving member 10 into an open state (separated state). Next, the receiving frame portion 2a is relatively inserted inside the cylindrical body S so that the embroidery region A in the cylindrical body S such as an arbitrary sleeve overlaps the embroidery window 9. After widening the embroidery area A in the tubular body S superimposed on the embroidery window 9 to eliminate wrinkles, the presser member 25 is lowered from the position of FIG. 4A to the position of FIG. 4B.
In this case, the portion S which is in a state of being stretched between the left and right end members 11c, 11c of the receiving member 10 is slightly pulled by the lowering of the anti-slip member 31 of the holding member 25 while being slightly pulled. It is pressed down in the state of FIG. 4 (B). When the substrate material 34 of the upper frame 3 is further pushed down by hand from this state, the substrate material 34 is lowered to the state of FIG. 4C against the spring force (repulsive force) of the leaf spring 50. At the same time, due to the spring force (pressing pressure) of the leaf spring 50, the portion S that was interposed between the receiving member 10 and the pressing member 25 has the upper surface of the flat receiving member 10 and the flat pressing member 25. It is elastically pressed and fixed from above and below while being sandwiched between the lower surface, i.e., flatly developed (no creases or the like are created around it).

Moreover, since the presser member 25 descends from above between the receiving member 10 and the presser member 25 and elastically approaches the upper surface of the receiver member 10, the thickness of the cloth portion S is relatively large. Even if it is a thing or a very thin cloth, it has the feature that these are pinched together and fixed together. Therefore, even if there is a difference in the fabric thickness between the portion S1 near the cuff and the portion S2, it is pressed and fixed in a uniform manner.
Further, in the process in which the presser member 25 moves from the position of FIG. 4A to the position of FIG. 4C, the locking claw 62 of the engagement mechanism 53 is moved to the position shown in FIGS. A) While descending while operating as described above using (B) and (C), the lowered state of the upper frame main body 3b is locked (maintained).

Next, the cloth portions S protruding from between the receiving member 10 and the pressing member 25 are respectively stored in the storage spaces 30 (the front side of 30a, the back side of 30b, and the space 30c on the left and right sides) of the upper part of the sleeve. Turn up. As a result, the lower surface of the lower frame 2 has no obstruction and becomes a flat sliding surface, and can be slid freely on the table T in the X-Y direction.
After the embroidery preparation is completed in this way, the joining member 22 provided on the back side of the embroidery frame is connected to the connecting member of the embroidery frame drive mechanism provided on the embroidery sewing machine, and is operated in a known manner. Desired embroidery is performed on the embroidery region A in the cylindrical body S such as a sleeve.
Thereafter, the operation pieces 58, 58 on both sides are pressed inward, respectively, and the movable engagement members 54 connected to the operation pieces 58 are respectively retracted to the retracted positions closer to the center, thereby raising the locking claws 62 to be free, The space between the receiving member 10 and the pressing member 25 is opened, and the cylindrical body S such as a sleeve is taken out.
In this case, the embroidery area A sandwiched between the receiving member 10 and the presser member 25 was sandwiched by pressure from above and below, and was not pulled with a strong force in the left-right direction. Even if the cloth is taken out between the receiving member 10 and the pressing member 25, there is no fear that the cloth shrinks, and the embroidery pattern applied to the cloth maintains a beautiful state.
