Abstract
Description
Technical Field
[0001] The utility model relates to clothing, and more specifically, to a down jacket. Background Art
[0002] A down jacket is a jacket filled with down filler, large and round in shape; most are worn by people in cold regions.
[0003] For clothing, heat preservation mainly focuses on the shoulders and back. Therefore, the better the heat preservation performance of the back of the down jacket, the better the overall heat preservation performance of the clothing.
[0004] In the existing down jackets, the back part of the down jacket is divided into multiple filling modules by sewing threads, and down is filled in the filling modules. The dividing line sews the inner and outer layers of the fabric of the down jacket tightly, resulting in no down filling at the sewing line position on the back, leading to easy heat loss at the sewing line and reducing the heat preservation performance of the down jacket. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a down jacket. Through the coverage of the upper knitting thread by the down strip, there is also down for heat insulation at the knitting thread position of the down, reducing the speed of heat loss from the back of the down jacket and improving the overall heat preservation performance of the down jacket.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions:
[0007] A down jacket includes a down inner liner on the back. The down inner liner includes a back cloth and down strips arranged in parallel from top to bottom. The down strips are located inside the back cloth; the upper edges of the down strips and the back cloth are provided with upper knitting threads for fixing, and the lower edges of the down strips are suspended along the back cloth; when the human back presses on the down inner liner, the deformed upper down strip above covers the upper knitting thread of the lower down strip.
[0008] By adopting the above technical solutions, since there is filled down in the down strip, and the outside of the down strip is the fabric wrapping the down, which is fixed on the back cloth by knitting and is in a long strip shape as a whole, so it is the down strip; and the parallel arrangement of the down strips from top to bottom is to facilitate the upper down strip to cover the adjacent upper knitting thread below in sequence. Since the up-and-down arrangement of the down strips is the same, a large number of the lower upper knitting threads can be covered, reducing the loss of hot air flow in the down jacket along the knitting thread position and improving the heat preservation performance.
[0009] The down bar is filled with down inside the fabric strip, so it is flexible. When a person wears a down jacket, the back of the human body will fit against the down bar, and the back of the human body will squeeze the down bar, causing the down bar to be flattened and deformed. The down bar will then move downward along the knitting line to achieve contact and cover the knitting line. After closing the down jacket, the squeezing effect of the down bar on the knitting line is more obvious. This squeezing and covering effect is achieved by fixing the knitting above the down bar without deformation allowance and allowing the lower part to hang freely and extend downward for extrusion.
[0010] Preferably, both sides of the down bar are knitted and fixed on both sides of the back cloth.
[0011] By adopting the above technical solution, both sides of the down bar are fixed, reducing heat loss to both sides. Moreover, the down bar fixed by knitting on three sides and the back cloth form a small heat-insulating cavity, improving the heat preservation performance.
[0012] Preferably, the width of the down bar is greater than the distance between two adjacent down bars.
[0013] By adopting the above technical solution, such a design is achieved by increasing the size and the amount of down in the down bar, enabling the down bar to cover the knitting line without being squeezed, further reducing the loss of hot air from the upper knitting line, and making the heat preservation performance more excellent.
[0014] Preferably, the lower edges of the down bar and the back cloth are arranged in parallel.
[0015] By adopting the above technical solution, it is comfortable and beautiful to wear.
[0016] Preferably, front panels are connected to both the left and right sides of the down inner liner, and inner pockets are provided on the front panels.
[0017] By adopting the above technical solution, the front panels refer to the clothing parts in front of the human body, which are divided into left and right parts, and the inner pockets are used to keep the items carried with the body warm.
[0018] Preferably, a set of outer pockets are provided on each of the two front panels, and the two sets of outer pockets are symmetrically arranged; a set of outer pockets includes an upper outer pocket and a lower outer pocket. An upper zipper is installed on the upper outer pocket, and a lower zipper is installed on the lower outer pocket. Both the upper zipper and the lower zipper are arranged in an inclined shape like an eight-character towards the center of the two front panels. The upper zipper inclines towards the center from top to bottom, and the lower zipper inclines towards the center from bottom to top. Both the upper zipper and the lower zipper are opened from top to bottom.
[0019] By adopting the above technical solution, multiple bag openings are provided to facilitate placing items during outdoor hiking and camping. The upper zipper and the lower zipper on the same side are arranged in an inclined V-shape facing the center, which is convenient for the user to open the zipper with the arm. Since the palm is located on the forearm of the human body, and most of the time the arm movement is that the forearm rotates around the back presenting an arc trajectory, the V-shaped layout just fits the rotation trajectory of the front panel along the posterior arm, making it easier for the palm to contact and open the zipper.
[0020] Both the upper zipper and the lower zipper are opened from top to bottom, which is also for the convenience of the user to open the zipper when swinging the lower forearm. Due to relatively cold weather, it is easier to pull down than to pull up. Therefore, the zipper is designed to be opened downward. The main purpose is to enable the user to more easily and quickly unzip and take out urgently needed items in extreme situations.
[0021] Preferably, a hat is provided above the down inner liner. The hat is provided with a drawstring for tightening the brim. The pulling end of the drawstring is located on the back of the hat, and an elastic buckle for clamping the drawstring is provided at the pulling end, and the elastic buckle is suspended on the hat.
[0022] By adopting the above technical solution, the design of the hat can increase the heat preservation of the user, and the rear placement of the drawstring can avoid hitting the user's face; the drawstring is positioned by the elastic buckle, which is convenient for the user to quickly grope backward to find the drawstring. Pressing the elastic buckle can loosen the drawstring, which is convenient for pulling the drawstring. After elastic loosening, it can reset and clamp under the action of elastic force to fix the drawstring again.
[0023] Preferably, a flexible sleeve is threaded through the drawstring on the outer side of the hat. The flexible sleeve slides on the drawstring, and the flexible sleeve is provided with an opening cavity for wrapping the elastic buckle.
[0024] By adopting the above technical solution, the flexible sleeve can wrap the elastic buckle. This setting is for the safety consideration of the back of the human head. Since the elastic buckle has a certain hardness, there will be a safety hazard once it hits the back of the head. In this design, the sliding flexible sleeve is used to cover the lower elastic buckle when it is idle. The elastic buckle can be taken out from the opening cavity when opening and closing. Since the flexible sleeve can be deformed, it is more convenient to take out. The flexible sleeve wrapping the elastic buckle reduces the impact force when the back of the head is hit and is safer.
[0025] Preferably, down strips are also arranged in parallel up and down on the inner side of the front panel.
[0026] By adopting the above technical solution, the front panel uses down strips with the same structure and the same arrangement as the down inner liner, improving the heat preservation performance of the user's chest.
[0027] Preferably, the width of the down strip is equal to the spacing between adjacent down strips.
[0028] By adopting the above technical solution, the down strip quilt can completely cover the knitting thread with a gentle squeeze, resulting in excellent heat preservation effect and beautiful shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0051] Embodiment 1, a down jacket, referring to Figure 1 and Figure 9 , a waterproof cloth layer is provided outside the down jacket, and a down inner liner 1 is provided inside the waterproof cloth layer. The down inner liner 1 is located on the back of the down jacket. The down inner liner 1 includes a back cloth 11 and down strips 12 arranged in parallel from top to bottom. The down strips 12 are long strip-shaped cavities sewn by cloth, and the cavities are filled with down.
[0052] As Figures 1 - 3 shown, the down strips 12 are located inside the back cloth 11, and the outside of the back cloth 11 faces the waterproof cloth layer; the lower edges of the down strips 12 and the back cloth 11 are arranged in parallel.
[0053] The upper edges of the down strips 12 and the back cloth 11 are provided with upper knitting threads 13 for fixing. The lower edges of the down strips 12 are suspended on the back cloth 11; the two sides of the down strips 12 are knitted and fixed on the two sides of the back cloth 11; the width of the down strips 12 is equal to the distance between two adjacent down strips 12. In this way, when hanging naturally, the lower edge of the upper down strip 12 just aligns with the upper knitting thread 13 of the lower down strip 12. Therefore, the lower edge of the down strip 12 and the upper knitting thread 13 coincide in the front view.
[0054] As Figure 4 shown, because the down strips 12 are relatively soft, when the back of the human body presses the down inner liner 1, the upper down strip 12 under pressure covers the upper knitting thread 13 of the lower down strip 12; when the down jacket of this design is worn on the human body, the back of the human body will press the down strips 12 on the back, causing the down in the down strips 12 to expand and extend downward to cover the upper knitting thread 13, reducing the amount of hot air flowing out at the upper knitting thread 13, thereby achieving a good heat preservation effect.
[0055] Referring to Figure 1 , Figure 5 and Figure 6 , both the left and right sides of the down inner liner 1 are knitted and connected with front panels 2. The front panels 2 are used to cover the front chest and abdomen of the user, and the two front panels 2 are connected by a zipper.
[0056] The front panel 2 is provided with an inner pocket 3. The inner pocket 3 is a mesh pocket for storing items. In other embodiments, the inner pocket 3 can also be a zippered bag body.
[0057] On the outer sides of both front panels 2, a set of outer pockets 4 are provided, and the two sets of outer pockets 4 are symmetrically arranged; one set of outer pockets 4 includes an upper outer pocket 41 and a lower outer pocket 42. An upper zipper 51 is installed on the upper outer pocket 41, and a lower zipper 52 is installed on the lower outer pocket 42. Both the upper zipper 51 and the lower zipper 52 are arranged obliquely in a V-shape towards the center of the two front panels 2. The upper zipper 51 is inclined towards the center from top to bottom, and the lower zipper 52 is inclined towards the center from bottom to top. Both the upper zipper 51 and the lower zipper 52 are opened from top to bottom.
[0058] A further optimization is that down strips 12 are also arranged in parallel up and down on the inner side of the front panel 2. The front panel 2 and the back inner liner insulate the human torso. The arrangement of the down strips 12 on the torso is the same as that on the back inner liner, so no repeated description will be given.
[0059] After a person wears the down jacket and zips up the front panel 2, the front and back down strips 12 are both pressed to cover the knitting thread below, achieving a further heat preservation effect.
[0060] A further optimization is that sleeves are provided on both sides of the down jacket. Down strips 12 can be arranged inside the sleeves. The down strips 12 are arranged along the length direction of the sleeves. Secondly, the down strips 12 form a ring on the sleeves, that is, the two knitting threads at both ends of the down strips 12 can be fixed by stitching them together with one strand.
[0061] Refer to Figure 7 and Figure 8 Above the down inner liner 1, a hat 61 is provided. The hat 61 is provided with a drawstring 62 for tightening the brim. The pulling end of the drawstring 62 is located on the back of the hat 61, and an elastic lock 63 for clamping the drawstring 62 is provided at the pulling end. The elastic lock 63 is installed on the hat 61 in a suspended manner through a fixing strap 64. Since one end of the stretch is fixed inside the front end of the hat 61, tightening the drawstring 62 can tighten the mouth of the hat 61, achieving a good heat preservation effect;
[0062] The elastic lock 63 is used to clamp and fix the pulled drawstring 62. The elastic lock 63 is a relatively common clothing accessory. Specifically, it passes the drawstring 62 through a housing 81. There is a clamping plate 82 inside the housing 81, and a spring 83 is below the clamping plate 82. The spring 83 pushes the clamping plate 82 upwards so that the clamping plate 82 and the edge of the through-hole of the housing 81 clamp the drawstring together to achieve a clamping effect. The upper part of the clamping plate 82 extends out of the housing 81 for the user to press. After pressing the clamping plate 82, the drawstring 62 is unlocked from the clamped state and can be pulled again.
[0063] Embodiment 2, a down jacket, which is different from Embodiment 1 in that, refer to Figures 10 - 11, a flexible sleeve 7 is threaded through a drawstring 62 on the outer side of the hat 61. The flexible sleeve 7 slides on the drawstring 62, and the flexible and thin sleeve is provided with an opening cavity 71 that wraps an elastic buckle 63.
[0064] The flexible sleeve 7 is a cloth sleeve filled with cotton. In other embodiments, other soft and fluffy substances can also be filled. The flexible sleeve 7 has a large deformation ability. Therefore, the user's finger can be inserted by opening the opening cavity 71. The flexible sleeve 7 is provided with a through hole for the drawstring 62 to pass through and slide freely;
[0065] The flexible sleeve 7 is sleeved on the fixing band 64. Therefore, it is blocked by the front and back of the hat 61 and the elastic buckle 63, and the flexible sleeve 7 can move on the fixing band 64;
[0066] Since the flexible sleeve 7 is relatively soft and fluffy, the flexible sleeve 7 and the elastic buckle 63 are in full extrusion contact. In the natural state, it is difficult for the two to separate. Only when the user actively opens the opening cavity 71, the two can be easily separated.
[0067] Embodiment 3, a down jacket, which is different from Embodiment 1 or Embodiment 2 in that, referring to Figure 12 , the width of the down strip 12 is greater than the distance between two adjacent down strips 12, and the width of the down strip 12 is 1.2 times the distance between two adjacent down strips 12.
[0068] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
