Note that the support mechanism 9 may be omitted when the base frame 11 does not have the front side horizontal frame member 11b' and the left side vertical frame member 11a.

The operation of the above configuration will be explained step by step.

When embroidering marks, names, etc. on the peripheral wall 10a of the golf bag 10, first the interval between the two clamping frames 12.degree. 12 is adjusted according to the size of the area on the peripheral wall 10a to be embroidered. To adjust the adjustment, lightly loosen the fastener 19 and
Just move it left and right along the horizontal frame members 11b, llb' and tighten the fasteners 19 again at the appropriate point.
If the area to be embroidered is small and the bag lO wobbles left and right if you match the spacing between the clamping frames 12 and 12 to that, then adjust the spacing between the clamping frames 12 to prevent the wobbling. 0 Next, the opening of the bag 10 is widened and the peripheral wall 10a is hung from a pair of support rods 14, 14 as shown in FIG. 2.3.4. in this case,
The free ends of the two support rods 14° 14 enter into the inner part of the bag through the opening, and then the respective support rods are rotated in directions away from each other around the shaft 21 in each clamping frame 12. let This operation may be performed for both clamping frames 12 at the same time, or one by one.The following describes the rotating operation of the clamping frame shown on the right side of Figure 2 in Figures 8A to 8.
This will be explained based on Figure E. First, from the state shown in FIG. 8A, the rotating body 22 is held by hand and rotated counterclockwise. Due to this rotation, the support rod 14 moves in the direction shown by the arrow, and eventually becomes in the state shown in FIG. 8B. In this process, the weight of the main body of the golf bag, for example, 4 to 5 kg, is applied to the peripheral wall 10a and is in frictional contact with the support rod 14, so that the peripheral wall 10a is pulled in the direction of the arrow by the zero-order In the state shown in FIG. 8B, the peripheral wall 10a comes into contact with the lower end of the positioning piece 29, and its vertical positioning (the state in which the peripheral wall 10a is located slightly 1 to 2 fi above the upper surface of the bed 5, or in contact with the upper surface of the bed 5) Next, when the rotating body 22 is further rotated counterclockwise from the state shown in FIG. 8B, it will eventually become a curved state as shown in FIGS. 8C and 9A. The free end of the support rod 14 that is in contact with the elastic member 26 of the clamping member 15 via the peripheral wall 10a. The lower end of the positioning piece 29 is polished to make its friction coefficient smaller than that of the circumferential surface of the support rod 14.
In the process from Figure 8B to Figure 8C above, the surrounding wall 1
0a is further pulled in the direction of the arrow 0 Next, when the state shown in FIG. 8C is reached, the operating lever 40 of the tightening device 16 is rotated in the direction of the arrow to move the piece 36 as shown in FIG. 8D. The upper surface of the holding member 15 is brought into contact with the upper surface of the holding member 15 as shown in FIG. Then, when the operating lever 40 is further rotated in the direction of the arrow shown in FIG.
Since the rotating body 22 to which the base 31 is fixed rotates around the pivot point 3 in the direction of the arrow in Fig. 8D, the rotating body 22 to which the base 31 is fixed is
As shown in the figure, it is drawn toward the holding member 15. During this pulling process, the curved support rod 1
4 is pulled toward the clamping member 15 against its own elasticity, and as shown in FIG. Member 15
The support rod 14 is held between an elastic member 26 and a support rod 14 provided therein. In the process from FIG. 8D to FIG. 8E, even if a large force is required to pull the curved support rod 14 toward the clamping member 15 against its elasticity. Since the drawing is performed by the action of the presser body 32 being rotated as described above by the toggle link 37, the operation can be easily performed with a small force. Of course,
Those who have sufficient physical strength should move from Figure 8C to Figure 8! ! Perform the rotation operation of the rotating body 22 up to the figure by hand, and
2 reaches the position shown in Fig. 8E, press the operating lever 4.
The tightening state between the clamping member 15 and the support rod 14 may be maintained by the tightening device 16 by the operation of 0.

By performing the above-described operation on the holding frame 12 on the left and right holding frames 12 in FIG.
The circumferential wall tOa between the support rods 14 is stretched tightly, and the entire area extending from the base to the free end of the support rod 14 is clamped as described above, and loosening of the entire area is prevented. It has become.

Next, when the embroidery sewing machine is operated, the needle 4 and hook operate, and the holding frame 6 is moved forward and backward and left and right according to a preset program by the forward and backward movement device 7 and the left and right movement device 8, and embroidery is made on the peripheral wall 10a. will be applied. In this case, since the upper peripheral wall 10a is held between the clamping member 15 and the support rod 14, the peripheral wall 10a is completely integrated with the holding frame 6 and moves back and forth and left and right, so that the accurate embroidery pattern can be sewn without collapsing. be done.

Next, different aspects of the embodiment will be explained. Each of the support rods 14 in both the clamping frames 12 has one of them fixedly connected to the base 1.
3 may be attached.

Furthermore, the direction in which the supporting rods 14 are rotated in the clamping frame 12 is opposite to that of the above embodiment, and there is also an example in which the supporting rods 14 are rotated in directions closer to each other. In this case, the circumferential wall 10a between the two support rods 14 can also be tensioned by the weight of the bag IO.

In this case, the surface of the support rod 14 is preferably formed to be smooth.

Next, the support rod 14 is not bent but remains straight, that is, parallel to the axis of its pivot point, and a bulge is formed at the free end of the support rod 14 as shown in phantom lines in FIG. Section 42
may be provided so that when the support rod 14 is rotated as described above, its free end approaches the clamping member 15 before the other portions. By doing so, the peripheral wall 10a is firmly held even at the free end of the support rod 14.

The bulge 42 is preferably made of an elastic material such as rubber and formed into a camp shape and placed over the tip of the support rod 14.

Alternatively, the support rod 14 is kept in a straight state as described above, and the holding member 15 is provided with a bulge 43 at a portion of the support rod that is in contact with the free end of the support rod, as shown by imaginary lines in FIG. The same effect as above may be performed.

Next, FIG. 10 shows another example in which a bulge is provided on the support rod. In this example, the support rod 14C is straight (
parallel to the axis of the pivot point), and has a bulge 44.4 at each part, for example, the tip, middle, and base.
5.46 is provided to increase the clamping force of the peripheral wall 10ae there. The dimensions of each bulge should be set such that the bulge on the distal side is larger and the bulge on the base side is smaller (for example, 3fl, 2fi, 1mm in order from the tip). The number of the bulges may be larger (and they may be arranged at close intervals).

It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with an alpha bent e, and redundant explanations are omitted.

〔Effect of the invention〕

As described above, in the present invention, when embroidering the peripheral wall 10a of the bag 1o, the two support rods 14 are inserted relatively into the opening of the bag 1o, and in this state, one of the support rods 14 is attached to the pivot point. 21 as an axis, the peripheral wall 10a of the bag 10 between the support rod 14 and the clamping member 15 is clamped and fixed, so when embroidering, the base frame is moved two-dimensionally and the bag 10 is 10 is driven, and the peripheral wall 10a of the bag 1o can be embroidered accurately.
