Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment production technology, specifically to a one-time forming template for patch pockets of ice silk elastic pants. Background Technology
[0002] Existing trouser patch pockets are generally located inside side pockets, back pockets, or on the trouser body, forming pockets within pockets for storing small items. The current manufacturing process for these patch pockets is complex (especially for elastic patch pockets), and manual sewing based on visual inspection is prone to errors (i.e., deviations in the opening direction and the relative position of the pocket to the side or trouser body). Specifically: the elastic patch pocket fabric (cut piece) is first heat-pressed to create the outer outline of the patch pocket; the outlined patch pocket is then attached to the trouser body or pocket fabric, and its position is adjusted; after positioning using a vector cardboard, three sides are sewn together, leaving an opening; the pocket is turned inside out and sewn at the seam for protection. The stop-sticker bag cracked during use; during the above process, the curved edges were not pressed evenly when the outer contour of the bag was heat-pressed at high temperature, and the overall shape was not easy to control; at the same time, due to multiple processes, disassembly and rotation, the dimensional accuracy was insufficient, and the bag-in-bag angle was easily incorrect after forming, resulting in many defective products; not only that, the elastic material and shape of the bag made it easy to bounce back during the heat pressing process, especially the curved corners were easy to twist and become uneven; in addition, when the stop-sticker bag and the bag fabric were sewn together, the fabric of the bag fabric also affected the forming effect, especially the ice silk elastic fabric, which is thin and smooth. During the sewing process, when pressing by hand and aligning with the cardboard, it is easy to push the fabric and slip, resulting in the bag-in-bag being skewed and uneven after sewing.
[0003] In conclusion, the existing patch pockets on ice silk elastic pants need further improvement and enhancement. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a one-time forming template for patch pockets of ice silk elastic pants. It has a simple structure, is easy to manufacture, easy to implement and has low cost. It solves the problems of irregularity and easy rebound of existing patch pocket heat pressing forming, and the opening direction shifts and the efficiency is low when sewing it with the garment body after multiple disassemblies and reassemblies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A one-time forming template for patch pockets in ice silk elastic pants, which is used to form patch pockets onto pants pockets or pants body in one step. The forming template includes a pocket fabric shaping plate group, a movable piece and a pants body positioning plate.
[0007] The bag fabric shaping plate assembly includes a base plate, two lateral sliding pieces, and a pressure plate. The base plate has a placement groove, two oppositely arranged recesses, and a sewing position along the inner edge of the placement groove. The placement groove is for inserting the bag fabric piece, and the width of the placement groove is smaller than the width of the bag fabric piece. The two lateral sliding pieces are oppositely arranged and slide in the recesses respectively, with the side edges and bottom edges of the lateral sliding pieces extending into the placement groove. The pressure plate covers and fixes the base plate, and the pressure plate has an opening corresponding to the placement groove.
[0008] The movable piece is adapted to the placement groove and placed inside the placement groove to press the bag fabric piece against the bottom of the placement groove and to fold the edge of the bag fabric piece to the upper surface of the movable piece.
[0009] A trouser body positioning plate is hinged to the bottom plate or pressure plate; the trouser body positioning plate is provided with a U-shaped sewing groove and a positioning edge, the U-shaped sewing groove is aligned with the sewing position, and the positioning edge is for the trouser body to be placed in alignment.
[0010] Furthermore, the side surfaces of the two sinks are inclined surfaces, which are used to guide the sliding pieces on both sides to slide along the inclined surfaces, so that the sides and bottom of the sliding pieces on both sides extend into the placement slots respectively.
[0011] Furthermore, a limiting edge is provided in the two sinks and at the position connected to the inclined surface to limit the distance that the two lateral sliding pieces extend into the placement slot.
[0012] Furthermore, it also includes a reset abutment portion, which is set at an obtuse angle to the inclined surface, so that the two lateral sliding pieces can smoothly exit the placement groove along the reset abutment portion.
[0013] Furthermore, the base plate is also provided with a trapezoidal protrusion, which is obliquely arranged on both sides and parallel to the inclined surfaces of the two sinks, so that the sidewall of the sink and the trapezoidal protrusion form a retraction channel for the lateral sliding piece to be reset.
[0014] Furthermore, the pressure plate is provided with a clearance portion corresponding to the retraction channel, so that a hand can reach in and grasp the two lateral sliding pieces.
[0015] Furthermore, the pressure plate is also provided with a ruler for aligning the bag fabric pieces, which is offset outward parallel to the sewing position.
[0016] Furthermore, the bottom of the placement groove and the area located in the middle of the sewing position are provided with an anti-slip part, which is used to increase the friction between the bottom plate and the bag fabric piece.
[0017] Furthermore, the trouser body positioning plate has a U-shaped flexible pressure pad attached to the middle area formed inward from the edge of the U-shaped sewing groove.
[0018] Furthermore, several anti-slip layers are laid on the trouser body positioning plate, which are located in the area between the U-shaped sewing groove and the positioning edge.
[0019] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:
[0020] This utility model discloses a one-time forming template for patch pockets of ice silk elastic pants. Its structure is simple, easy to manufacture, readily achievable, and low in cost. The new template uses a placement groove and a movable piece to press the pocket fabric piece in place. Then, two lateral sliding pieces are used to fold the pocket fabric piece inwards, ensuring a smooth fold at the curved corners. Finally, it is placed on the flat and positioned pant body positioning plate. The movable piece and lateral sliding pieces are then removed. At this point, the pocket fabric piece and pant body are perfectly aligned and clamped. After one sewing step, it can be directly formed. The resulting bag is flat, smooth, and precisely sized, with the bag opening aligned with the trouser body. Even with elastic fabrics like ice silk, the finished product maintains a smooth texture. More importantly, the forming process is greatly simplified, eliminating the need for heat pressing and shaping. This saves many steps, such as heat pressing, multiple marking and positioning. After shaping, any bulging areas at the folds do not need to be repositioned and flattened, eliminating concerns about rebound after heat pressing. Production efficiency is also significantly improved, more than five times that of traditional sewing, making it suitable for mass production. Attached Figure Description

[0033] In the claims, description and drawings of this utility model, the terms "comprising", "having" and variations thereof are used to mean "including but not limited to".
[0034] See Figure 1-5The embodiment described herein is a one-time forming template for patch pockets of ice silk elastic pants, which is used to form patch pockets into pants pockets or pants body in one step; patch pockets generally refer to small pockets, which can be used to place some important small items, such as cash, valuable jewelry, USB flash drives, multi-tools, and can also be used to place some small smart control boxes, etc. In addition, they can also play a good decorative role and have a high aesthetic appeal.
[0035] In this embodiment, the forming template includes a pocket fabric shaping plate group 1, a movable piece 2, and a trouser body positioning plate 3;
[0036] The bag fabric shaping plate assembly 1 includes a base plate 4, two side sliding plates 5, and a pressure plate 6;
[0037] The base plate 4 is provided with a placement groove 41, two oppositely arranged sinkers 44, and a sewing position 42 along the inner edge of the placement groove 41.
[0038] The placement groove 41 is used to place the bag fabric piece A, and the width of the placement groove 41 is smaller than the width of the bag fabric piece A. Then, the edges of the bag fabric piece A are pushed inward by the sliding pieces 5 on both sides to form a folded edge.
[0039] In order to improve the anti-slip effect between the bag fabric piece A and the base plate 4 and prevent twisting and pushing of the fabric during sewing, an anti-slip part 43 is laid at the bottom of the placement groove 41 and in the middle of the sewing position 42. This part is used to increase the friction between the base plate 4 and the bag fabric piece A.
[0040] The two lateral sliding pieces 5 are arranged opposite each other and are respectively placed in the two sinks 44 and slide, so that the side and bottom edges of the two lateral sliding pieces 5 extend into the placement groove 41. It should be noted that the side groove surfaces of the two sinks 44 in this embodiment are inclined surfaces 441, which are used to guide the two lateral sliding pieces 5 to slide along the inclined surfaces 441, so that the side parts 51 and bottom parts 52 of the two lateral sliding pieces 5 extend into the placement groove 41 respectively. Using the inclined surfaces 441 as guides, the two lateral sliding pieces 5 push the bag fabric piece A into the placement groove 41 smoothly without jamming, and without swaying or loosening, and are pressed tightly together before sewing.
[0041] Furthermore, a limiting edge 442 is provided in the two sinking grooves 44 and at the position connected to the inclined surface 441 to limit the distance of the two lateral sliding pieces 5 extending into the placement groove 41. This design effectively limits the two lateral sliding pieces 5 from pushing the side edge A1 and bottom edge A2 of the bag fabric cut piece A. In particular, when the bottom edge A2 is folded, it abuts against the limiting edge 442, ensuring that the two lateral sliding pieces 5 are symmetrical and aligned, thus playing a good shaping role.
[0042] The pressure plate 6 is placed on the base plate 4 and fixed, and the pressure plate 6 has an opening 61 corresponding to the placement groove 41; the pressure plate 6 is placed on the base plate 4, so that the sink 44 forms a clamping space, which is only allowed to move to the sliding piece 5 on both sides, so that the bag fabric piece A will not curl up when it is folded and pressed, and the pressing is more flat.
[0043] In addition, the pressure plate 6 is also provided with a ruler part 62 for aligning the bag fabric piece A, which is offset outward parallel to the sewing position 42 for the placement of the bag fabric piece A.
[0044] The movable piece 2 is adapted to the placement groove 41 and placed inside the placement groove 41. It is used to press the bag fabric piece A against the bottom of the placement groove 41 and fold the side edge A1 and bottom edge A2 of the bag fabric piece A to the upper surface of the movable piece 2. In this embodiment, the movable piece 2 is slightly smaller than the width of the placement groove 41, but larger than the maximum width of the sewing position 42.
[0045] The trouser body positioning plate 3 is hinged to the bottom plate 4 or the pressure plate 6; the trouser body positioning plate 3 is provided with a U-shaped sewing groove 31 and a positioning edge 32, the U-shaped sewing groove 31 is aligned with the sewing position 42, and the positioning edge 32 is for the trouser body to be placed in alignment.
[0046] Furthermore, the trouser body positioning plate 3 has a U-shaped flexible pressure pad 33 attached to the middle area formed inward from the edge of the U-shaped sewing groove 31 to press the trouser body more tightly and prevent it from coming loose during sewing. This not only provides frictional shaping but also has a certain degree of elasticity during sewing, making it easier to adjust the looseness and resulting in a smoother and higher-quality sewn product. Several anti-slip layers 34 are laid on the trouser body positioning plate 3, which are located in the area between the U-shaped sewing groove 31 and the positioning edge 32.
[0047] More specifically, it also includes a reset abutment part 443, and the remaining inclined surfaces 441 are set at obtuse angles so that the two side sliding pieces 5 can smoothly exit the placement groove 41 along the reset abutment part 443, thus ensuring smooth reset (retraction) and preventing jamming or incomplete reset during reset.
[0048] More specifically, a trapezoidal protrusion 7 is also provided on the base plate 4 and corresponding to the sink 44. The trapezoidal protrusion 7 is obliquely arranged on both sides and parallel to the inclined surface 441, so that the side wall of the sink 44 and the trapezoidal protrusion 7 form a retraction channel 445 for the lateral sliding piece to reset. This further improves the stability of the operation reset. The operator operates according to the formed retraction channel 445, which is fast and not easy to deviate, with higher accuracy and more suitable for mass standardized production.
[0049] In addition, the pressure plate 6 is provided with a relief portion 64 corresponding to the retraction channel 445, so that the hand can reach in and grasp the two side sliding pieces 5, making it convenient for the operator to reach in and operate.
[0050] In actual production and use: see Figure 1-7 ,
[0051] (1) A base plate 4 and a pressure plate 6 are made of transparent acrylic sheet. The base plate 4 is placed on a carving machine. According to the digital programming, the carving machine will mill a placement groove 41, a U-shaped sewing position 42, a groove 44 and a retraction channel 445 on the upper surface of the base plate 4. The height of the groove 44 and the retraction channel 445 is slightly higher than the thickness of the two side sliding pieces 5, so that they have a certain amount of looseness when moving. Moreover, the side of the groove 44 is set with an obtuse angle, that is, it forms an inclined surface 441 and a reset abutment. The side near the placement groove 41 forms a limiting edge 442 to prevent the side sliding pieces from excessive displacement when sliding.
[0052] (2) Two lateral sliding pieces 5 are made, which have the same shape as the sink 44. After forming, the part of the U-shaped sewing position 42 is cut off first, and then cut into two symmetrical lateral sliding pieces 5. After forming, they are placed in the sink 44 respectively, and they are aligned with the retraction channel 445. Under the guidance of the inclined surface 441, they can slide and cover the U-shaped sewing position 42. The lateral sliding pieces 5 in this embodiment are also provided with round holes 50 for fingers to move at the end.
[0053] (3) Place the acrylic pressure plate 6 on the engraving machine to open the relief part, engrave the scale part 62, and the U-shaped opening 61 corresponding to the U-shaped sewing position 42. The scale part 62 is also U-shaped and its size is larger than the U-shaped sewing position 42. The relief groove allows the hand to easily move the side sliding piece.
[0054] (4) Place the pressure plate 6 on the base plate 4 and lock the two together by fixing.
[0055] (5) Similarly, the trouser body positioning plate 3 is prepared by acrylic sheet, and the U-shaped sewing groove 31 is opened by engraving machine and the trouser body alignment scale is engraved. Then, a flexible pressure pad 33 is attached to the middle area inside the edge of the U-shaped sewing groove 31, and an anti-slip layer 34 is attached to other areas (the sandpaper layer is used as an example in this embodiment).
[0056] (6) The trouser body positioning plate 3 and the pressure plate 6 are hinged together by adhesive tape, and the formed pocket fabric shaping plate group 1 can be flipped over on the trouser body positioning plate 3.
[0057] During the sewing process:
[0058] (1) First, cover the cut piece A of the bag fabric with the cut sheet A on the pressure plate 6 and align it with the scale part 62 along its edge;
[0059] (2) Take out the movable piece 2, press down the bag fabric piece A from the opening and press it into the placement groove 41. It should be noted that at this time, the side and corner of the movable piece 2 correspond to the side and corner of the U-shaped placement groove, respectively. Press down the movable piece 2 and press the bag fabric piece A together into the placement groove 41. At this time, the side A1 part of the bag fabric piece A is raised upward, and the middle part is flattened by the movable piece 2 and held between the bottom surface of the placement groove 41 and the movable piece 2.
[0060] (3) The operator pushes the lateral sliding pieces 5 forward from the clearance part. Under the action of the inclined surface 441, the lateral sliding pieces 5 move horizontally towards the middle of the placement groove 41, flipping and pushing the raised side A1 and bottom A2 parts towards the middle of the placement groove 41, and pressing them down by the lateral sliding pieces 5. The other lateral sliding piece 5 operates in the same way, so that the side A1 and bottom A2 of the bag fabric piece A are folded towards the middle of the placement groove 41 and pressed down between the lateral sliding piece 5 and the upper surface of the movable piece 2. It should be noted that the two lateral sliding pieces 5 are pushed along the inclined surface 441 until they are pressed down to the edge of the limiting edge 442, which is the push-up and pressing down. In addition, the transparent acrylic plate can also be used to observe whether it is in place by the naked eye.
[0061] (4) At this time, the bag fabric shaping board group 1 is equivalent to folding the edge of the bag fabric piece A and positioning it, so that it can be sewn into shape later.
[0062] (5) Place the trouser body piece B on the trouser body positioning plate 3 and align it with the positioning edge 32 so that the trouser body piece B covers the U-shaped sewing groove 31; after covering, use the flexible pressure pad 33 and the anti-slip layer 34 to prevent slipping or twisting during sewing.
[0063] (6) Flip the pocket fabric shaping plate group 1 and cover it on the trouser body positioning plate 3; then, first pull the movable piece 2 outward, at this time the pocket fabric piece A still remains shaped; then slide the sliding pieces 5 on both sides back to their original positions. At this time, since the bottom plate 4 and the pressure plate 6 are flipped onto the trouser body positioning plate 3, after being pulled out, they still remain U-shaped and pressed onto the trouser body piece. Under the action of the flexible pressure pad 33, the flipped edge of the pocket fabric piece A is pressed onto the trouser body piece B, and it is not easy to loosen and rebound.
[0064] (7) Place it on the sewing machine and sew along the sewing position 42 opened on the base plate 4. It can be sewn into shape in one go. The U-shaped patch bag is aesthetically pleasing, flat, and matches the size and direction of the trouser body.
[0065] This utility model discloses a one-time forming template for patch pockets of ice silk elastic pants. Its structure is simple, easy to manufacture, readily achievable, and low in cost. The new template uses a placement groove and a movable piece to press the pocket fabric piece in place. Then, two lateral sliding pieces are used to fold the pocket fabric piece inwards, ensuring a smooth fold at the curved corners. Finally, it is placed on the flat and positioned pant body positioning plate. The movable piece and lateral sliding pieces are then removed. At this point, the pocket fabric piece and pant body are perfectly aligned and clamped. After one sewing step, it can be directly formed. The resulting bag is flat, smooth, and precisely sized, with the bag opening aligned with the trouser body. Even with elastic fabrics like ice silk, the finished product maintains a smooth texture. More importantly, the forming process is greatly simplified, eliminating the need for heat pressing and shaping. This saves many steps, such as heat pressing, multiple marking and positioning. After shaping, any bulging areas at the folds do not need to be repositioned and flattened, eliminating concerns about rebound after heat pressing. Production efficiency is also significantly improved, more than five times that of traditional sewing, making it suitable for mass production.
[0066] The description of the above specification and embodiments is used to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model.
