Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attachment for a sewing machine that is used when sewing a lining to the tip of a necktie.

[Prior Art] Conventionally, this type of attachment has not been provided with a temporary fixing needle for fixing the point of the tip of the sword on the outer material A.

[Problems to be solved by the invention] Since the conventional one did not have temporary fixing needles, the corner pick-up members 9, 1 at the central apex and both apexes were
0 and 10' and the protruding grooves 25, 26, and 26', the gripping stops at the center apex part A' and both side apex parts A'' and A'' of the outer material A are set at the center when the outer material restraining plate 20 starts to fall down. Start pinching the apex part A', and at the end of the fall, start pinching the apex parts A'' and A'' on both sides, and complete the pinching of the central apex part A' and both apex parts A'' and A''. They will end almost at the same time. However, unwillingly, each vertex of the outer material A is
It collapses into a somewhat rounded state due to subtle effects such as a time difference due to changes in the inclination angle of the outer material restraining plate 20 and stretching due to the presence of the height of the center and both corner pick-up members. There were some undesirable defects, such as misalignment, and so-called tangles at the tip of the finished product.

[Means for Solving the Problems] The present invention is designed to attach the outer material A to the outer material restraining plate 2 with the apex A' of the outer material A secured by temporary fixing needles 16.
By fixing the value to 0, the above-mentioned defects are solved.

[Embodiment of the invention] The embodiment shown in the figure is based on an imaginary pentagon with the size of the tip of a necktie developed on a base plate 1 made of opaque hard plastic. A lower passage groove 2 for a sewing machine needle (not shown) is bored in the bottom surface of the base plate 1, and a lower passage groove 2 for the sewing machine needle (not shown) is provided at a location parallel to one incisal edge of the lower passage groove 2. A lining is provided with a guide rack 3 to be used when moving it to the base plate 1 so as to pass through the passage groove 2, and has a pentagonal part 4 on the upper surface of the lower side of the base plate 1 at the front, which is one size smaller than the above-mentioned pentagon. The plastic lining restraining plate 5 is attached with a hinge 6 so that it can be raised and lowered freely, and when it is laid down, the pentagonal part 4 should be located in the center of the area surrounded by the lower passage groove 2, and the central apex of the pentagonal part 4 should be Knife-shaped corner pick-up members 9, 10, 10' are attached to the center and both-side apex points 12, 7 and both sides of the lower passage groove 2, respectively. 13, 13' are attached in a transverse state, and a stiff sponge swelling member 14 is fixed to the top surface of the pentagonal part 4 to give the outer material a fullness. The outer restraining plate 20 is supported by a hinge 21 so that it can be raised and lowered freely, and when the outer restraining plate 20 is collapsed, it communicates with the lower passage groove 2 at a line corresponding to the lower passage groove 2. the upper passage groove 22 of the sewing machine needle, and the upper passage groove 2 of the sewing machine needle.
2, the central apex portion 23 and both side apex portions 2
4, 24' are the corner pick-up members 9, 1.
0 and 10' protruding grooves 25, 26, and 26' are bored, respectively, and the outer fabric suppression plate 20 is provided in a portion surrounded by the upper passage groove 22 of the outer fabric suppression plate 20.
An inverted plate-shaped bulge 27 into which the bulging member 14 fits when the 0 is collapsed is integrally formed, and a portion parallel to one incisal edge of the upper passage groove 22 on the upper surface of the outer material restraining plate 20. (Some parts have both incisal edges)
A protruding running surface 28 is provided on which the presser foot (not shown) of the sewing machine slides, and a protruding track surface 28 is provided on the upper surface of the outer incisal edge of the central apex portion 23 in the lower passage groove 2 of the base plate 1. A temporary fixing needle 16 for pricking the tip of the tip of the sword is erected through a stand 17.

In the figure, reference numeral 30 indicates a positioning member for outer material A and lining material B, 31 indicates an abutting member for determining the position of the pusher of the sewing machine at the beginning of sewing, and 32 indicates a window.

[Operation of the invention] Since the present invention has the above-described configuration, first, as shown in FIGS. 1 and 2, the lining is placed on the base plate 1 with its surface facing upward, and the outer edge is is placed so that it straddles both incisal edges of the lower passage groove 2, and then the lining restraint plate 5 is folded down, and then the outer material A is placed on this lining restraint plate 5 with the lining facing upward. The point of the tip of the outer material A is stuck into the temporary fixing needle 16, and this outer material A is attached to the lining restraining plate 5 in a superimposed state corresponding to the above-mentioned lining B (in this case, the three of the lining B and the outer material A are The apex is directly below the corner pick-up members 9, 10, 10',
Make sure it is positioned directly above. ) (see Figs. 3 and 4), and then fold down the outer material restraining plate 20 to expose the central apex portion A' and both side apex portions A'' and A'' of the outer material A. Corner pick-up members 9, 1 for the center and both apexes
0 and 10' and the protruding grooves 25, 26, and 26', the grip is secured (see FIGS. 5 and 6), and the setting of the lining and outer fabric is completed.

After this setting is completed, the outer periphery of the outer material A, which is in a state of being overlapped in the upper and lower passage grooves 22, 2, and the lining material B is sewn together using a sewing machine, and after this sewing, the outer material A is removed from the attachment of the present invention. This is used for purposes such as flipping the whole thing inside out and completing the installation of the lining.

The left half shown in FIGS. 1, 3, and 5 is used for lining the larger tip, and the right half is used for lining the smaller tip.

[Effect of the invention] The present invention has the above-mentioned central apex part A′ of the outer material A.
After fixing it on the temporary fixing needle 16, the apex part A'' on both sides,
A'' is clamped by the outer fabric restraining plate 20, and is effective in fully achieving the intended purpose.
