Description

Technical Field

[0001] The utility model relates to a stand-up collar structure for a down jacket, belonging to the technical field of clothing. Background Art

[0002] The stand-up collar structure of a down jacket refers to the collar part of the down jacket. The stand-up collar structure is usually designed to enhance warmth, comfort and appearance. The stand-up collar structure is particularly important because the collar area directly contacts the neck and is easily invaded by cold air.

[0003] Because the restrictions on fillings in traditional down jacket stand-up collars are not clear enough, or simple sewing methods are used, the movement and deformation of the fillings during long-term wear or washing are not fully considered.

[0004] In a typical stand-up collar, if the down or other filling isn't properly secured or restrained, it can shift during wear, washing, and other processes. This can cause down to gather in some areas, leaving others relatively empty, resulting in uneven warmth across the collar. This shifting filling not only compromises warmth but also causes the collar to lose its crispness and shape, preventing it from retaining its original shape. Utility Model Content

[0011] The shaping assembly includes several groups of first shaping strips sewn in the first limiting area, and the first shaping strips are sewn and fixed to the additional piece, the secondary collar piece, and the main body.

[0012] As a further improvement, the shaping component also includes staggered shaping lines extending from the end of the first shaping strip toward the upper middle part, and the shaping lines are sewn and fixed to the additional piece and the auxiliary collar piece to form several restricted areas, and the filler is filled and fixed in the restricted areas.

[0013] As a further improvement, the additional piece is in a fine grid structure, and the additional piece is provided with fine velvet hooks on the side facing the secondary collar piece, and the velvet hooks are in contact with the filling.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0031] In a typical stand-up collar, if the down or other filling isn't properly secured or restrained, it can shift during wear, washing, and other processes. This can cause down to accumulate in some areas, leaving others relatively empty, resulting in uneven warmth across the collar. This shifting filling not only compromises warmth but also causes the collar to lose its crispness and shape.

[0032] Reference Figure 1-4 As shown, a down jacket stand-up collar structure includes:

[0033] A main collar piece 2 sewn onto the main garment body 1, a secondary collar piece 3 arranged on the outer side of the main collar piece 2, and an additional piece 4 arranged between the main collar piece 2 and the secondary collar piece 3;

[0034] A channel 41 is formed between the additional piece 4 and the secondary collar piece 3. A filler 5 is provided in the channel 41. A limit portion is provided from the main collar piece 2 toward the secondary collar piece 3. A shaping component is provided on the limit portion. The shaping component is sewn and fixed to the additional piece 4 and the secondary collar piece 3.

[0035] The movement space of the filler 5 is limited by the cooperation between the shaping component, the additional piece 4 and the auxiliary collar piece 3.

[0036] The main collar piece 2 faces outwards, and the secondary collar piece 3 fits the neck.

[0037] The secondary collar piece 3, which conforms to the neck, and the additional piece 4, together constrain the filling 5 and limit its movement, ensuring uniform distribution. The main collar piece 2, facing outward and separated from the filling 5 by the additional piece 4, reduces direct impact of the filling 5 on the main collar piece 2, thus preventing its impact on the appearance and maintaining a consistently upright collar shape. This improves the overall stiffness and shape stability of the stand-up collar. The stitching of the shaping assembly, the additional piece 4, and the secondary collar piece 3 limits the movement of the filling 5, maintaining an upright collar shape while preventing deformation or collapse.

[0038] By meticulously controlling the filler 5, maintaining its shape, and improving its warmth, this design effectively addresses several issues with existing stand-up down collars. The coordination of the secondary collar piece 3, which conforms to the neck, the additional piece 4, which isolates the filler 5, and the shaping components ensures the stand-up collar's uprightness, warmth, and comfort. Compared to traditional solutions, this design offers improved filler 5 stability and overall shape, meeting consumers' high demands for both functionality and aesthetics.

[0039] The limiting portion includes a first limiting area 42 provided at the connection between the main collar piece 2 and the main garment body 1;

[0040] The shaping assembly includes a plurality of first shaping strips 43 sewn to the first limiting area 42 , and the first shaping strips 43 are sewn and fixed to the additional piece 4 , the secondary collar piece 3 , and the main garment body 1 .

[0041] The support coefficient of the main collar piece 2 is improved by the cooperation of the first shaping strips 43 with the additional piece 4 and the auxiliary collar piece 3 .

[0042] The first limiting region 42 is located where the main collar panel 2 connects to the main body 1. This region forms the foundation for the stand-up collar and the down jacket body, ensuring the stability and load-bearing capacity of the stand-up collar structure. This limiting region controls the deformation of the filler 5 and the stand-up collar structure by acting as a limiter, preventing the collar structure from deforming as the filler 5 moves.

[0043] The first limiting area 42 supports the stand-up collar, thereby forming a relatively stable connection between the stand-up collar and the main garment body 1. This can help prevent the stand-up collar structure from loosening or sagging under prolonged use or external pressure.

[0044] The first limiting area 42 limits the movement space of the filler 5 at the bottom of the stand-up collar, ensuring that the filler 5 remains evenly distributed in the stand-up collar, thereby ensuring the stability of the warming effect.

[0045] The first shaping strip 43 is a shaping component sewn to the first limiting area 42. By fixing it to the seams of the additional piece 4, the secondary collar piece 3 and the main garment body 1, it can enhance the support and stiffness of the stand-up collar.

[0046] The first shaping strips 43, as a structural reinforcement device, are evenly distributed in the first limiting area 42 through multiple groups of shaping strips. They can effectively improve the overall support coefficient of the stand-up collar, making the stand-up collar upright and less prone to deformation, especially in the down jacket collar, an area that is often subjected to stress.

[0047] To further optimize the stability of the stand-up collar structure and the distribution of the filler 5, the shaping component also includes a staggered shaping line 44 extending from the end of the first shaping strip 43 toward the upper middle part. The shaping line 44 is sewn and fixed to the additional piece 4 and the secondary collar piece 3 to form a plurality of restricted areas. The filler 5 is filled and fixed in the restricted areas.

[0048] The shaping line 44 extends upward from the end of the first shaping strip 43, staggered to form a plurality of seam intersections, and together with the additional piece 4 and the secondary collar piece 3, forms a plurality of small restricted areas. Each restricted area has a filler 5, which can further accurately limit the movement of the filler 5.

[0049] The filler 5 is fixed in a relatively small space by the restricted areas defined by the shaping lines 44, preventing it from moving freely over a large area. This makes the filler 5 more evenly distributed and prevents it from shifting or accumulating due to prolonged wear or external pressure, thereby ensuring the warmth and shape of the stand-up collar.

[0050] Because the filler 5 is fixed in multiple restricted areas, its distribution is more even, which means that different parts of the stand-up collar can maintain the same warmth retention performance, avoiding local temperature differences, thereby improving the wearer's comfort and windproof warmth retention.

[0051] Sewing the shaping strips and shaping lines 44 not only secures the filler 5 but also enhances the overall structural stability of the stand-up collar. The stand-up collar is subject to significant external forces (such as friction from zippers or neck movement), effectively reducing deformation caused by these forces and enhancing the durability of the stand-up collar.

[0052] In addition, the edges of the additional piece 4 and the secondary collar piece 3 are both sewn and fixed to the main collar piece 2 .

[0053] By adding shaping lines 44 to the shaping strips, several restricted areas are formed, allowing the filler 5 to be more precisely and stably fixed within the stand-up collar. This not only improves the uniformity of the filler 5, ensuring warmth, but also enhances the support and stiffness of the stand-up collar, avoiding the problems of filler 5 shifting or unstable in traditional stand-up collars. Compared to traditional designs, this design offers improved warmth retention, shape retention, and comfort, representing an innovative and aesthetically pleasing design.

[0054] The additional sheet 4 is a fine grid structure, and the side of the additional sheet 4 facing the secondary collar sheet 3 is provided with fine velvet hooks 45, and the velvet hooks 45 fit the filling 5. The additional sheet 4 is velvety non-woven cotton.

[0055] The first shaping strip 43 has a length of 2-3 cm and a width of 0.5-1 cm.

[0056] Among them, flat sewing is done at 6cm on the front neckline of the main collar piece 2 without taking any measurements to prevent the collar from being too large. Measure 0.3cm-0.4cm on the upper and lower collars to form inner and outer roundness, so that the collar remains naturally upright.

[0057] The additional sheet 4 has a fine grid structure and has fine velvet hooks 45 on the side facing the secondary collar sheet 3, which can fit tightly with the filler 5. This can better fix the filler 5 and prevent it from moving or deforming during use.

[0058] The hooks 45 fit tightly against the filler 5, reducing slippage or displacement of the filler 5 during use and ensuring uniform distribution of the filler 5 throughout the stand-up collar. Because the filler 5 is better secured, the filler 5 is evenly distributed throughout the stand-up collar, preventing areas of excessive thickness or thinness, and ensuring the overall warmth retention of the stand-up collar.

[0059] Because the hooks are densely packed with small hooks, similar to the hard-surface velvet hooks 45 of Velcro, each hook is thin and resilient, allowing it to firmly bond with the surface fibers of the filler 5. The hook ends of the velvet hooks 45 are slightly curved inward, effectively embedding into the surface fibers of the filler 5, creating a strong mechanical fixation effect.

[0060] Compared with the traditional Velcro hard-surface velvet hook 45, the velvet hook 45 is finer and softer, and the hook-shaped structure is smaller and denser, which can reduce the wear on the filler 5 while maintaining a firm fixing force, and is softer to the touch, avoiding causing discomfort to the wearer's skin.

[0061] The velvet hook 45 is made of a high polymer material with good flexibility, which has certain elasticity and durability. This material can not only withstand multiple pulling and friction without deformation or breakage, but also can be repeatedly embedded with the filler 5 without damaging the fiber structure.

[0062] The polymer material used in the velvet hooks 45 is typically made of nylon or polyester fibers. These materials are characterized by high toughness, good wear resistance, and strong fatigue resistance. They can maintain the integrity of the velvet hooks 45 despite repeated friction and pulling, and will not break or lose their fixing effect after long-term use.

[0063] The interlocking hooks 45 and the fibers on the surface of the filler 5 create a secure hold, preventing the filler 5 from shifting within the stand-up collar. The dense arrangement of the hooks 45 allows for multiple points of contact with the filler 5, ensuring uniform distribution of the filler 5 throughout the collar, avoiding any accumulation or gaps. Because the hooks 45 are fine and gentle, they minimize damage to the fiber structure of the filler 5, extending the life of the filler 5 and maintaining its warmth.

[0064] In addition, the additional sheet 4 is selected to use velvet non-woven cotton, which is soft, light and has good warmth retention. At the same time, its texture has certain elasticity and breathability, and is suitable for use as a filler 5 fixed structure in the down jacket stand-up collar.

[0065] The soft feel of the velvety non-woven cotton not only enhances the comfort of the secondary collar panel 3 and the neck, but also reduces friction and wear on the filling 5. The non-woven cotton acts as a barrier to the filling 5, effectively maintaining its warmth without adding to the overall bulk of the stand-up collar. The breathability of the non-woven cotton ensures that the stand-up collar remains comfortable while wearing, enhancing comfort.

[0066] The length and width of the shaping strip, 2-3 cm in length and 0.5-1 cm in width, are designed based on the actual needs of the stand-up collar and the characteristics of filler 5. This design of the shaping strip maintains support without excessively restricting or stiffening the collar. It provides sufficient support to maintain the stand-up collar's crisp shape without excessively affecting the collar's overall softness and wearing comfort. The width of the shaping strip is designed to provide a certain degree of flexibility, allowing it to adjust to the changes in the stand-up collar's shape, preventing the collar from appearing too rigid.

[0067] Sew the main collar piece 2 flat at 6cm from the front neckline to ensure that the collar does not oversize. This is to prevent excess fabric from piling up in the collar area, making the stand-up collar appear heavy and clumsy, affecting the appearance of the garment.

[0068] By controlling the amount of sewing in specific areas and preventing excessive accumulation of fabric, the overall crispness of the stand-up collar can be maintained without causing the shape to become loose due to excess fabric accumulation.

[0069] Flatbed sewing not only makes the seams of the neckline neater, but also reduces the accumulation of excess fabric at the neckline, making the overall appearance of the clothing more beautiful.

[0070] The offset of the upper and lower necklines is set to 0.3cm-0.4cm. The offset in this range can form natural arcs inside and outside, making the stand-up collar fit the neck better when worn while keeping the collar upright.

[0071] The design of the backing helps the collar form a natural curve, ensuring that the stand-up collar fits naturally around the neck when worn, increasing wearing comfort while maintaining a good upright effect. The appropriate backing ensures the collar's softness, avoiding the stiffness or looseness caused by excessive or insufficient backing, keeping the collar both straight and natural.

[0072] In this embodiment, the first shaping strip 43 has a length of 2.2 cm and a width of 0.6 cm.

[0073] Example 2

[0074] Reference Figure 5 As shown, this embodiment is basically the same as embodiment 1, except that: when the stand-up collar is longer, the limiting portion further includes a second limiting area 46 provided in the middle of the secondary collar piece 3;

[0075] The shaping assembly includes a plurality of second shaping strips 47 sewn to the second limiting area 46 , and the second shaping strips 47 are sewn and fixed to the additional piece 4 and the auxiliary collar piece 3 .

[0076] The shaping component also includes a shaping line 44 extending from the end of the second shaping strip 47 toward the upper / lower middle, and the shaping line 44 is sewn and fixed to the additional piece 4 and the secondary collar piece 3 to form a plurality of restricted areas, and the filler 5 is filled and fixed in the restricted areas.

[0077] The second limiting area 46 effectively controls the movement of the filler 5 in the middle of the stand-up collar through further separation and support, thereby enhancing the supporting force of this area and ensuring that the stand-up collar can remain upright and evenly distributed even when its length increases.

[0078] The second shaping strip 47 is sewn to the second retaining zone 46, further strengthening the central structure of the stand-up collar. This not only increases the support strength of the central region but also effectively prevents the filler 5 from shifting or accumulating due to gravity or external pressure. The second shaping strip 47 is sewn and fixed to the additional panel 4 and the secondary collar panel 3. This three-layered seam ensures a tight connection between the various components of the stand-up collar, thereby enhancing the overall structural stability.

[0079] By adding the second shaping strip 47, the shape of the longer portion of the stand-up collar is further strengthened so that it will not be easily deformed when subjected to external force or when worn.

[0080] The addition of the second shaping strip 47 not only separates the filler 5 in the upper and lower sections, but also limits the movement of the filler 5, ensuring that the filler 5 is evenly distributed in the upper and lower sections of the longer stand-up collar, thereby avoiding local accumulation or insufficient filling.

[0081] In addition, the shaping lines 44 extend upward or downward from the end of the second shaping strip 47 in a staggered manner to form multiple seam fixing points. This staggered extension design can further divide the stand-up collar into multiple restricted areas, effectively controlling the distribution of the filling 5.

[0082] The shaping line 44 strengthens the overall support of the stand-up collar by being sewn together with the additional piece 4 and the secondary collar piece 3, and at the same time forms a number of restricted areas in which the filler 5 is evenly fixed, thus avoiding the problem of uneven distribution of the filler 5 that may occur due to a long stand-up collar.

[0083] The staggered shaping lines 44 divide the stand-up collar into smaller areas, effectively confining the filling 5 within these areas and ensuring even distribution of the filling 5. The shaping lines 44 provide precise support and fixation, allowing the stand-up collar to maintain its natural upright position even when extended, preventing sagging or deformation.

[0084] The second shaping strip 47 has a length of 1-2 cm and a width of 0.3-0.5 cm. The density of the filler 5 above the second limiting area 46 is 100 g / m 2 The density of the filler 5 in the second limiting area 46 and the first limiting area 42 is 150 g / m 2 .

[0085] Wherein, the filling material 5 is down.

[0086] In this design, the size designs of the first shaping strip 43 and the second shaping strip 47 have different focuses. They play different roles in enhancing the stiffness of the stand-up collar, especially in different areas of the stand-up collar, with the change in the density of the filler 5, which further improves the shape stability and wearing effect of the stand-up collar.

[0087] The first shaping strip 43 is relatively long and wide, designed to provide strong support for the main structure of the stand-up collar, especially in the area near the neckline. This area is often subjected to greater pressure, such as external forces and friction when worn, so a larger support area is required to ensure the overall upright shape of the stand-up collar. This area is relatively dense because the filler 5 has a relatively high density (150g / m 2 ).

[0088] The second shaping strip 47 is smaller in size and does not increase the hardness too much, ensuring that the middle part of the stand-up collar maintains a certain degree of flexibility and a natural curvature, thus avoiding the stand-up collar not fitting well or causing discomfort when wearing due to the shaping strip being too hard. The filler 5 above the second limiting area 46 has a low density (100g / m 2 ), increasing the overall support in this area, so only a smaller size shaping strip is needed to assist, which also reduces the feeling of excessive stiffness.

[0089] #In the stand-up collar, the different densities of the filler 5 will affect its shape support. The design optimizes the overall shape of the stand-up collar by adjusting the size of the shaping strip and coordinating the density of the filler 5.

[0090] The density of the filler 5 in the upper part (above the second limiting area 46) is 100g / m 2

[0091] Lower density filler 5: The upper area filler 5 has a lower density (100g / m 2), is relatively light and has weak support, requiring the larger area and strength of the first shaping strip 43 to enhance the stiffness of the stand-up collar. In areas where the filler 5 is lighter, the second shaping strip 47, with its larger support area, helps the stand-up collar maintain its shape, preventing the upper part of the stand-up collar from sagging or folding due to insufficient support from the filler 5.

[0092] The density of the filler 5 in the lower part (second limiting area 46) is 150g / m 2

[0093] The filler 5 in the lower area has a higher density (150g / m 2 ), the filler 5 in this area itself has good support, and in order to further improve the stiffness, a larger first shaping strip 43 is used to provide auxiliary support.

[0094] Improve regional support and enhance overall shape stability: the first shaping strip 43 and the second shaping strip 47 provide main support and auxiliary support respectively according to the density of the filler 5. In the upper part where the filler 5 is lighter, the smaller second shaping strip 47 provides the main support force to keep it straight; while in the lower area where the filler 5 is denser, the first shaping strip 43 provides auxiliary shape maintenance to strengthen and ensure the overall structural stability of the stand-up collar.

[0095] The combination of five different filler densities and the sizing of the molding strips not only ensures the stand-up collar remains crisp and stable, but also prevents it from being too rigid, preserving its natural curves. The layered design, with a lighter upper section and a thicker lower section, makes the stand-up collar more ergonomic, aesthetically pleasing, and comfortable to wear.

[0096] In this embodiment, the second shaping strip 47 has a length of 1.5 cm and a width of 0.4 cm.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
