This is for guiding the positions of the connecting members 13 and 14 in the left-right direction with respect to the holder 9 when the holders 8 and 9 are attached. The guide groove 44 is formed in a shape that gradually becomes narrower from the back end 44a toward the deep part of the guide groove 44 in order to enable smooth guidance. 45 and 46 are engagement holes and fitting holes provided in the connecting members 13 and 14 of the pair of fitting portions, and the engagement convex portions 31a and the fitting convex portions 31 are fitted respectively. Correspondingly formed as possible. These fitting engagement holes 45 and 46 exemplify through holes, but may be bottomed recesses that open on the lower surfaces of the connecting members 13 and 14. These fitting engagement portions 45 and 46 are located at positions corresponding to the fitting engagement convex portions 31 and 31a, that is, when the connecting members 13 and 14 are brought into a predetermined position with respect to the holding members 21 and 22, respectively. It is provided at the position where it overlaps with 31 and 31a. The fitting engagement recesses 45 and 46 corresponding to these are provided on the embroidery object 15 attached to the holder 10 so that the fitting state with the fitting engagement projections 31 and 31a is maintained firmly. It is provided at the front end portions 13b and 14b on the side where the load applied to the receiving surfaces 21a and 22a from the connecting members 13 and 14 increases greatly due to the weight. The engaging recess 45 is arranged between the back side and the front side, and a large shrinkage force is generated in the embroidery object due to an increase in the number of embroidery needles to the embroidery object, and the shrinkage force reduces the width dimension of the inner frame 41. Even if a situation arises, a long hole that is long in the left-right width direction is formed in order to prevent biting with the engaging protrusion 31a due to the reduction. The relationship between the convex portion and the concave portion is relative to the positioning of the pair of fitting portions (31, 45, 46) and the function of transmitting the force in the horizontal direction, and the fitting portions 31, 31a are fitted. On the other hand, the fitting portions 45 and 46 may be formed in the corresponding fitting convex portions while being formed in the mating concave portions. Also, the installation position may be the front side of the presser spring 33 (FIG. 2), but it may be in the middle of the presser portions 36, 38 on the lower side of the presser spring 33. Further, the pair of guide members composed of the guide piece 30 and the guide groove 44 are relative, the connecting member 14 side may be tapered, and the holder 9 side may be formed in a corresponding funnel-shaped recess.
[0013]
A case where the embroidery object 15 is embroidered using the embroidery frame 11 will be described. When embroidery is performed on the embroidery object 15, the embroidery object 15 is mounted on the embroidery frame 11 so that the planned embroidery position of the embroidery object 15 is located in the embroidery space 12. Next, the embroidery frame 11 is loaded into the holders 8 and 9. The operation advances the embroidery frame 11 into the space between the left and right holders 8 and 9 toward the back, and the left and right connecting members 13 and 14 move the receiving surfaces 21a and 22a of the holding members 21 and 22 in the holders 8 and 9, respectively. Insert under the spring 33 along 22a. In this case, the insertion of the connecting member 14 will be described as an example with reference to FIG. The connecting member 13 is inserted in parallel with the connecting member 14. First, as shown in (A), the end portion 14a is advanced in the direction of the arrow 47 and is slid under the presser portion 36 along the receiving surface 22a. The reason why the arrow 47 is inclined is to avoid interference between the connecting member 14 and the fitting convex portion 31. However, since the fitting convex portion 31 is formed with a low height as described above, the inclination may be extremely small enough to clear the fitting convex portion 31, and is inserted in a state substantially along the receiving surface 22a. Can be done. Next, as shown by arrow 48 in (B), the end portion 14a is directed to the gap 27. In this case, since the end portion 14a is pressed downward by the pressing portion 38, the end portion 14a can be directed to the gap 27 without causing the end portion 14a to abut against the levitation prevention body 26. In this case, the guide member 30 is advanced so as to enter the guide groove 44, so that the connecting member 14 is guided to the holder 9 in an appropriate position in the left-right direction. As a result, the fitting recess 46 smoothly moves to a position where it overlaps with the fitting projection 31. In addition, when the right and left positions of the connecting member 14 are appropriate, the left and right positions of the connecting member 13 with respect to the holder 8 are also interlocked with each other. When the connecting member 14 is advanced as described above and the tip of the connecting member 14 comes into contact with the stopper 28, the fitting recess 46 is overlapped with the fitting protrusion 31. Then, as shown in (C), the end 14b of the connecting member 14 is lowered onto the receiving surface 22a, the fitting recess 46 is fitted with the fitting projection 31, and the engagement hole 45 is engaged with the engagement projection 45. Fit with the part 31a. With the above operation, the embroidery frame 11 is attached to the holders 8 and 9 at a predetermined position.
[0014]
Next, as shown in FIG. 7, when the trainer 15 is attached to the embroidery frame 11, it may be noticed that the attached state is opposite to that shown in FIG. In this case, it is not necessary to remove the embroidery object 15 and reattach it as in the prior art. That is, of the two guide grooves 44, 44, the guide groove 44 (one groove 44 of the coupling members 13, 14) having a preferable orientation suitable for the state of the trainer 15 is replaced with one of the holding members 21, 22. The coupling members 13 and 14 may be attached to the holding members 21 and 22 toward the guide piece 30 in the same manner as described above. Then, regardless of which guide groove 44, 44 is directed to the back side, the coupling members 13, 14 with respect to the guide piece 30, the fitting convex portion 31, and the engaging convex portion 31a on the holding members 21, 22 The guide grooves 44, 44 on the side, the fitting holes 46, 46, and one of the engagement holes 45, 45 are arranged so as to fit each other. If they are changed by 180 degrees, they are integrated in the horizontal direction.
[0015]
Next, the operation at the time of embroidery on the embroidery object loaded in the embroidery sewing machine 1 as described above will be described. The drive frame 7 moves in the directions of arrows 7a and 7b in FIG. 1 based on a predetermined program. The movement is transmitted to the embroidery frame 11 through the holding members 21 and 22, the fitting engagement convex portions 31 and 31 a, the fitting engagement concave portions 45 and 46, and the connecting members 13 and 14, and the embroidery object 15 is integrated with the drive frame 7. It moves to. In synchronism with the movement, the needle bar 5 moves up and down, and the embroidery 15 is embroidered by the needle 6. In the above case, since the holding portion 36 of the pressing spring 33 prevents the coupling members 13 and 14 from being lifted, the fitting state between the fitting concave portions 45 and 46 and the fitting convex portions 31 and 31 is maintained extremely firmly. . Therefore, the accuracy of movement of the embroidery object 15 is stably maintained, and the embroidery object 15 is stably embroidered with a predetermined pattern stably. The fitting state between the fitting concave portions 45 and 46 and the fitting convex portions 31 and 31 is also maintained by a load applied to the connecting members 13 and 14 due to the weight of the holder 10 and the weight of the embroidery object 15.
[0016]
Removal of the embroidery frame 11 after completion of embroidery is performed in the reverse procedure to the above. That is, first, the end portion 14b is lifted from the state of FIG. 4C, and the fitting recess 46 and the fitting projection 31 are disengaged. Similarly, with respect to the connecting member 13, the fitting concave portion 45 and the fitting convex portion 31 are disengaged. Next, when the embroidery frame 11 is pulled forward, the connecting members 13 and 14 come out from between the holding members 21 and 22 and the pressing spring 33, and the embroidery frame 11 is detached from the holders 8 and 9.
[0017]
Next, in the case of the above embroidery, when the embroidery object 15 is a garment such as a trainer and embroidery is performed on its chest and back, the fitting engagement concave portions 45 and 46 and the fitting engagement convex portions are also provided for the following reason. The certainty of maintaining the fitting state with 31, 31a is increased. That is, when embroidery is performed in the above place, the embroidery frame 11 is positioned with respect to the embroidery object 15 in the relationship shown in FIG. The center of gravity of the embroidery frame 11 is substantially at the center position of the embroidery frame 11 as indicated by symbol G when the embroidery object is not attached. However, when the embroidery object 15 as described above is mounted, the position of the center of gravity in the mounted state becomes a front side position as compared with the case where the embroidery object 15 is not mounted as indicated by the symbol G ′ due to the weight of the sleeve 15a. For this reason, the load applied from the connecting members 13 and 14 to the receiving surfaces 21a and 22a greatly increases on the end portions 13b and 14b side. Due to the increased load, the end portions 13b and 14b are more difficult to lift from the receiving surfaces 21a and 22a, and the fitting state between the fitting convex portions 31 and 31 and the fitting concave portions 45 and 46 is firmly maintained.
[0018]
Next, the example of FIG. 6 is intended to prevent erroneous damage to the push spring when the embroidery frame is attached to the holder. In the figure, reference numeral 50 denotes a deformation limiting member for preventing excessive deformation of the pressing spring 33e, which is formed of a hard material and is fixedly provided at a position as shown. The deformation limiting member 50 limits the deformation of the portion near the base 34e of the pressing spring 33e by the connecting member when the embroidery frame is attached within the range of its elastic limit. As a result, it is possible to prevent an accident that the pressing spring 33e is permanently deformed and the connecting member cannot be pressed. In addition, the part which is considered functionally the same or equivalent to the thing of the previous figure, and overlaps description is attached | subjected to the code | symbol same as the previous figure, and the overlapping description is abbreviate | omitted.
[0019]
【The invention's effect】
