Description

Technical Field

[0001] This invention relates to the field of garment loop sewing technology, and more specifically to an auxiliary device for garment loop sewing. Background Technology

[0002] Currently, sword-shaped shoulder and sleeve loops are common garment components, mainly used in work pants, trench coats, overcoats, and various military uniforms. When processing these standard shoulder and sleeve loops, garment factories typically rely on manual sewing by garment workers. The process involves first fixing two pieces of fabric together, right sides facing, aligning them, and sewing them together. After pressing and turning them inside out, they are shaped and ironed again. The sewing process requires first sewing around the edge, then sewing another layer near the edge, ensuring the two seams are as parallel as possible to meet the requirements. However, because the entire process is done by hand, it is not only time-consuming and labor-intensive, but also prone to issues such as misalignment of the two fabric pieces, noticeably crooked stitching, and significant differences in appearance, resulting in a poor final product. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides an auxiliary device for sewing garment loops.

[0004] An auxiliary device for sewing garment loops includes a first composite flap, a second composite flap, and a third composite flap. The first composite flap can be placed on top of the second composite flap so that the back of the first composite flap contacts the front of the second composite flap. The second composite flap can be placed on top of the third composite flap so that the back of the second composite flap contacts the front of the third composite flap. The third composite flap has a first through-slot with a sword-head structure, the same shape as the garment loop, located at the rear. A first pressing strip extending rearward is fixed to the front end of the first through-slot, and a first threading gap is formed between the side of the first pressing strip and the left, right, and rear sides of the first through-slot. The second composite flap has a second through-slot with a sword-head structure, the same shape as the garment loop, located at the rear. The second through slot has a rearwardly extending and overlapping second and third pressing strips fixed to its front end face. A second threading gap is formed between the side of the second pressing strip and the left, right, and rear sides of the second through slot. The first composite flap has a third through slot with the same shape as the garment loop and a sword head structure. An mounting piece fixed to the first composite flap is provided in the third through slot. A bent and extended stop strip protrudes from the back of the mounting piece. When the first composite flap is placed on the second composite flap, the third through slot coincides with the second through slot. The stop strip is inserted into the second threading gap and surrounds the side of the third pressing strip. An outer threading gap is formed between the side of the stop strip and the left, right, and rear sides of the second through slot. When the second composite flap is placed on the third composite flap, the second through slot coincides with the first through slot.

[0005] Preferably, it also includes a pressing strip, and a first slot is provided at the bottom of the back of the second composite flip plate. The first slot extends straight backward and connects to the second through slot. The opening of the first slot connecting to the second through slot is located between the second pressing strip and the third pressing strip. The pressing strip can be inserted into the second through slot along the first slot. After the fabric piece is placed into the second through slot, the pressing strip is inserted into the second through slot along the first slot. The pressing strip passes between the second and third pressing strips, flattening the entire fabric piece during the process. Furthermore, during the overlapping of the second and third composite flip plates, the pressing strip is positioned within the second through slot, allowing the operator to flip and hold the fabric piece in place. Due to the non-deformable nature of the pressing strip, the fabric piece is less likely to move during flipping, improving the alignment of the two fabric pieces after overlap. More importantly, if slight unevenness is found between the two fabric pieces after the second and third composite flip plates overlap, the pressing strip can be directly inserted into the first slot. The pressing strip enters the second through slot between the second and third pressing strips, while the fabric piece is positioned between the second and first pressing strips, avoiding direct large-area contact with the fabric piece. This also flattens the fabric piece, eliminating unevenness and improving the subsequent sewing effect.

[0006] Preferably, a first limiting structure is provided at the top of the first slot, allowing the push-to-open strip to pass between the first slot and the first limiting structure. The first limiting structure can limit the push-to-open strip to a certain extent, increasing the speed at which the user inserts the push-to-open strip and preventing the push-to-open strip from damaging the structure of the second and third pressing strips.

[0007] Preferably, the device further includes a pressing strip. A second slot is provided at the bottom front of the third composite flip plate. The second slot extends straight backward and connects to the first through slot. The pressing strip can be inserted into the first through slot along the second slot. Similarly, when the fabric piece is placed in the first through slot, the pressing strip can pass through the first pressing strip after entering the first through slot along the second slot, and flatten the entire fabric piece during the passage. Likewise, during the overlapping of the second and third composite flip plates, the pressing strip is located in the first through slot, allowing the operator to flip and press the fabric piece simultaneously. Based on the non-deformable nature of the pressing strip, the fabric piece is less likely to move during flipping, improving the alignment of the two overlapping fabric pieces.

[0008] Preferably, a second limiting structure is provided at the top of the second slot, allowing the push-to-open strip to pass between the second slot and the second limiting structure. Similarly, the second limiting structure can limit the push-to-open strip to a certain extent, increasing the speed at which the user inserts the push-to-open strip and preventing it from damaging the structure of the first pressing strip.

[0009] Preferably, a first friction strip is provided on the front side of the first pressing strip. The first friction strip can increase the maximum static friction between the fabric and the first pressing strip, preventing the fabric from moving easily.

[0010] Preferably, a second friction strip is provided on the back of the second pressing strip. The second friction strip can increase the maximum static friction between the fabric and the second pressing strip, preventing the fabric from moving easily.

[0011] Preferably, the third composite flap has a first line on its front side, which surrounds the first through groove and has the same shape as the garment loop. The size of the first line can be freely adjusted. When the size of the fabric piece to be sewn is larger than the first through groove, the operator can align the first line with the fabric piece, effectively improving sewing efficiency.

[0012] Preferably, the back of the second composite flap is provided with a second line, which surrounds the second through groove and has the same shape as the garment loop. Similarly, the size of the second line can be freely adjusted. When the size of the fabric piece to be sewn is larger than the second through groove, the operator can align the second line with the fabric piece, effectively improving sewing efficiency.

[0013] The beneficial effects of this invention are reflected in:

[0014] In this invention, during use, two pre-formed sword-head fabric pieces are first prepared. Then, the second and third composite flaps are unfolded, with one fabric piece placed in the first through groove and the other in the second through groove. The fabric pieces are the same size as the first and second through grooves. The second composite flap is then placed directly on top of the third composite flap, with the back of the second composite flap contacting the front of the third composite flap. The first and second through grooves overlap, so that the two fabric pieces are neatly overlapped and positioned between the second and first pressing strips. Then, the third pressing strip is pressed by hand. Because the third pressing strip overlaps with the second and first pressing strips, it can... This allows the two fabric pieces to be pressed tightly together. At this point, a portion of the surface of the two fabric pieces is exposed through the second threading gap. This exposed surface is precisely where the two round stitches will be formed. Then, the first composite flap is placed on top of the second composite flap, and the third through groove coincides with the second through groove. The stop strip located in the third through groove is directly inserted into the second through groove, and the stop strip surrounds the entire third pressing strip. At this point, a portion of the surface of the two fabric pieces is exposed through the outer threading gap. This exposed surface is precisely where the outer stitches will be formed. Finally, the operator moves the entire auxiliary device to align with the sewing needle, and while holding down the third pressing strip, begins to sew the outer stitches. By following the exposed stitching, the surrounding side structure of the outer thread gap can be used as a reference, eliminating the need to consider the stitching direction, position, and distance. This greatly improves the operator's sewing efficiency and the straightness of the stitches. After the outer stitching is completed, the entire auxiliary device is moved away from the sewing needle, and the first composite flap is moved away from the front of the second composite flap. At this point, a portion of the two fabric pieces is exposed through the second thread gap. This portion of the surface is precisely where the two stitches will form. The operator then moves the entire auxiliary device to align with the sewing needle and begins sewing while holding down the third pressing strip. Based on the already completed outer stitch, the operator can use the surface around the third pressing strip as a reference to begin sewing the inner stitch. Similarly, using this reference eliminates the need to consider the direction, position, and distance of the stitches, greatly improving sewing efficiency and straightness. Once the inner stitch is finished, the entire sewing operation is complete. The entire sewing process is simple and convenient, saving time, effort, and steps. It also effectively avoids misalignment between two fabric pieces, obvious skewed stitches, and large differences in shape, significantly improving the sewing effect. Attached Figure Description

[0026] like Figures 1 to 4 As shown, an auxiliary device for sewing garment loops includes a first composite flap 1, a second composite flap 2, and a third composite flap 3. The first composite flap 1 can cover the second composite flap 2 so that the back of the first composite flap 1 contacts the front of the second composite flap 2. The second composite flap 2 can cover the third composite flap 3 so that the back of the second composite flap 2 contacts the front of the third composite flap 3. The third composite flap 3 has a first through groove 31 with the same shape as the garment loop and a sword-head structure. The sword-head structure of the first through groove 31 is located on the rear side. A first pressing strip 32 extending rearward is fixed to the front end of the first through groove 31. A first threading gap is formed between the side of the first pressing strip 32 and the left, right, and rear sides of the first through groove 31. The second composite flap 2 has a second through groove 21 with the same shape as the garment loop and a sword-head structure. The sword-head structure of the second through groove 21 is located on the rear side. The front end face of the two-way slot 21 is fixed with a rearwardly extending and overlapping second pressing strip 22 and a third pressing strip 23. A second threading gap 4 is formed between the side of the second pressing strip 22 and the left, right and rear sides of the second through slot 21. The first composite flap 1 is provided with a third through slot 11 that is the same shape as the garment loop and has a sword head structure. An installation piece 12 fixed on the first composite flap 1 is provided in the third through slot 11. A bent and extended stop strip 13 is protruding from the back of the installation piece 12. When the first composite flap 1 is covered on the second composite flap 2, the third through slot 11 coincides with the second through slot 21. The stop strip 13 is inserted into the second threading gap 4 and surrounds the side of the third pressing strip 23. An outer ring threading gap 5 is formed between the side of the stop strip 13 and the left, right and rear sides of the second through slot 21. When the second composite flap 2 is covered on the third composite flap 3, the second through slot 21 coincides with the first through slot 31.

[0027] In this embodiment, it should be noted that when using the entire auxiliary device, first, two pre-formed sword-head fabric pieces are prepared. Then, the second composite flap 2 and the third composite flap 3 are unfolded, with one fabric piece placed in the first through groove 31 and the other fabric piece placed in the second through groove 21. The size of the fabric pieces is the same as the size of the first through groove 31 and the second through groove 21. Then, the second composite flap 2 is directly placed on the third composite flap 3, with the back of the second composite flap 2 contacting the front of the third composite flap 3, and the first through groove 31 and the second through groove 21 overlapping, so that the two fabric pieces are neatly overlapped and located between the second pressing strip 22 and the first pressing strip 32. Then, the third pressing strip 23 is pressed by hand, and the... When the third pressing strip 23 overlaps with the second pressing strip 22 and the first pressing strip 32, the two fabric pieces can be directly pressed together. At this time, a portion of the surface of the two fabric pieces is exposed through the second threading gap 4, which is exactly where the two round stitches are formed. Then, the first composite flap 1 is placed on the second composite flap 2, and the third through groove 11 overlaps with the second through groove 21. The stop strip located in the third through groove 11 is directly inserted into the second through groove 21, and the stop strip surrounds the entire third pressing strip 23. At this time, a portion of the surface of the two fabric pieces is exposed through the outer ring threading gap 5, which is exactly where the outer ring stitches are formed. Finally, the operator moves the entire auxiliary device directly to align the sewing needle. While holding down the third pressing strip 23, begin sewing the outer ring seam. By following the exposed part of the stitch, the operator can use the surrounding side structure of the outer ring threading gap 5 as a reference, eliminating the need to consider the stitching direction, position, and distance. This greatly improves the operator's sewing efficiency and the straightness of the stitches. After the outer ring seam is sewn, move the entire auxiliary device away from the sewing needle, and then move the first composite flap 1 away from the front of the second composite flap 2. At this point, a portion of the surface of the two fabric pieces is exposed through the second threading gap 4. This portion of the surface is precisely where the two ring seams will form. The operator then moves the entire auxiliary device to align with the sewing needle and, by hand... While holding down the third pressing strip 23, begin sewing the inner circle seam. Based on the already sewn outer circle seam, the operator can use the surrounding surface of the third pressing strip 23 as a reference to begin sewing the inner circle seam. Similarly, by using the reference, there is no need to consider the direction, position, or distance of the stitching, which greatly improves the operator's sewing efficiency and the straightness of the stitches. Once the inner circle seam is sewn, the entire sewing operation is complete. The entire sewing process is simple and convenient, saving time, effort, and steps. It also effectively avoids misalignment between the two fabric pieces, obvious skewed stitching between the two circles, large differences in shape, and other issues, greatly improving the sewing effect.

[0028] Specifically, it also includes a flat insert 6. The bottom back of the second composite flip plate 2 has a first slot 24. The first slot 24 extends straight back and connects to the second through slot 21. The opening of the first slot 24 connecting to the second through slot 21 is located between the second pressing strip 22 and the third pressing strip 23. The flat insert 6 can be inserted into the second through slot 21 along the first slot 24.

[0029] In this embodiment, it should be noted that after the fabric piece is placed into the second through groove 21, the pressing strip 6 is inserted into the second through groove 21 along the first slot 24. The pressing strip 6 can pass between the second pressing strip 22 and the third pressing strip 23, and flatten the entire fabric piece during the passing process. Furthermore, during the overlapping of the second composite flip plate 2 and the third composite flip plate 3, the pressing strip 6 is located in the second through groove 21, and the operator can press the fabric piece while flipping it. Based on the characteristic that the pressing strip 6 is not easily deformed, the fabric piece can be flattened during the flipping process. It is not easy to move during the process, which improves the alignment of the two pieces of fabric after they are overlapped; more importantly, after the second composite flip plate 2 and the third composite flip plate 3 overlap, if a slight unevenness is found between the two pieces of fabric, the flattening insert 6 can be directly inserted into the first slot 24. The flattening insert 6 enters the second through slot 21 and is located between the second pressing strip 22 and the third pressing strip 23, while the fabric is located between the second pressing strip 22 and the first pressing strip 32. It will not directly contact the fabric over a large area, and it can also flatten the fabric, eliminate the unevenness on the fabric, and improve the subsequent sewing effect.

[0030] Specifically, a first limiting structure 241 is provided at the top of the first slot 24, and the flat insert 6 can pass through the first slot 24 and the first limiting structure 241.

[0031] In this embodiment, it should be noted that the first limiting structure 241 can limit the pressing strip 6 to a certain extent, increase the speed at which the user inserts the pressing strip 6, and also prevent the pressing strip 6 from damaging the structure of the second pressing strip 22 and the third pressing strip 23.

[0032] Specifically, it also includes a flat insert 6, and a second slot 33 is provided at the bottom front of the third composite flap 3. The second slot 33 extends straight backward and connects to the first through slot 31. The flat insert 6 can be inserted into the first through slot 31 along the second slot 33.

[0033] In this embodiment, it should be noted that, similarly, after the fabric piece is placed into the first through groove 31, the pressing strip 6 is inserted into the first through groove 31 along the second slot 33. The pressing strip 6 can pass through the first pressing strip 32 and flatten the entire fabric piece during the passing process. Similarly, during the overlapping process of the second composite flip plate 2 and the third composite flip plate 3, the pressing strip 6 is in the first through groove 31. The operator can flip and press the fabric piece at the same time. Based on the characteristic that the pressing strip 6 is not easily deformed, the fabric piece is not easy to move during the flipping process, which improves the alignment degree after the two fabric pieces overlap.

[0034] Specifically, a second limiting structure 331 is provided at the top of the second slot 33, and the flat insert 6 can pass through the second slot 33 and the second limiting structure 331.

[0035] In this embodiment, it should be noted that, similarly, the second limiting structure 331 can limit the pressing strip 6 to a certain extent, increase the speed at which the user inserts the pressing strip 6, and also prevent the pressing strip 6 from damaging the structure of the first pressing strip 32.

[0036] Specifically, a first friction strip 321 is provided on the front side of the first pressing strip 32.

[0037] In this embodiment, it should be noted that the first friction strip 321 can increase the maximum static friction between the fabric and the first pressing strip 32, preventing the fabric from moving easily.

[0038] Specifically, a second friction strip 221 is provided on the back of the second pressing strip 22.

[0039] In this embodiment, it should be noted that the second friction strip 221 can increase the maximum static friction between the fabric and the second pressing strip 22, preventing the fabric from moving easily.

[0040] Specifically, the front of the third composite flap 3 is provided with a first line 34, which surrounds the first through groove 31 and has the same shape as the garment loop.

[0041] In this embodiment, it should be noted that the size of the first line 34 can be freely adjusted. When the size of the fabric piece to be sewn is larger than the first through groove 31, the operator can align the first line 34 with the fabric piece to effectively improve sewing efficiency.

[0042] Specifically, the back of the second composite flap 2 is provided with a second line 25, which surrounds the second through groove 21 and has the same shape as the garment loop.

[0043] In this embodiment, it should be noted that, similarly, the size of the second line 25 can be freely adjusted. When the size of the fabric piece to be sewn is larger than the second through groove 21, the operator can align the second line 25 with the fabric piece to effectively improve sewing efficiency.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
