Description

Technical Field

[0001] The present invention relates to the technical field of clothing, and particularly relates to a filling bag with adjustable warmth retention and a warm clothing. Background Art

[0002] Warm clothing refers to clothing designed to keep the body warm in cold environments. Most of them achieve warmth retention by filling the interior of the clothing with synthetic fibers, chemical fiber cotton or down, so as to form a warm air chamber in the filling cavity; for example, down jackets are filled with down for warmth retention to minimize the loss of body heat and block the intrusion of external cold air.

[0003] However, the warmth retention of current warm clothing mainly depends on the type and weight of the filling material. Since the filling cavity of the warm clothing is sealed, the warmth retention is fixed after the warm clothing is sewn, and it cannot meet the diverse needs of the wearer for warmth retention in different scenarios. Summary of the Invention

[0004] The purpose of the present invention is to provide a filling bag with adjustable warmth retention and a warm clothing, which can adjust the warmth retention of the warm clothing by optimizing the structure of the filling cavity, effectively cope with the changes in personal physical condition, environmental temperature and exercise intensity, and meet the diverse needs of the wearer in different scenarios.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A filling bag with adjustable warmth retention, connected to a clothing, includes:

[0007] A filling bag body, the interior of the filling bag body is filled with a filling material; and,

[0008] A traction member, the traction member includes an adjustment section and a traction section arranged in sequence. One end of the adjustment section is connected to the filling bag body, and the adjustment section is attached to the inner wall or outer wall of the filling bag body along the circumferential direction of the filling bag body to form an adjustment loop;

[0009] When pulling the traction section, the adjustment loop is contracted to reduce the volume inside the filling bag body; when releasing the traction section, the volume inside the filling bag body increases.

[0010] Preferably, the adjustment section is arranged on the inner wall of the filling bag body, and an inner bag is arranged inside the filling bag body, and the filling material is filled inside the inner bag.

[0011] Preferably, a limiting channel is arranged on the side wall of the filling bag body along the movement path of the adjustment section, and at least part of the adjustment section penetrates inside the limiting channel.

[0012] Preferably, the side wall of the filling package body is connected with a guide bar, so that the limiting channel is formed between the guide bar and the side wall of the filling package body.

[0013] Preferably, the guide strip is sewn or glued to the filling bag body.

[0014] Preferably, both sides of the guide strip in the length direction are sealingly matched with the side walls of the filling package body.

[0015] Preferably, the adjustment section is elastic stretch fabric or metal wire.

[0016] Preferably, the filling bag with adjustable warmth retention also includes:

[0017] The auxiliary expansion mechanism is configured to assist in expanding the internal volume of the filling bag body when the traction section is relaxed.

[0018] The thermal insulation garment comprises a garment body and a filling bag with adjustable thermal insulation properties, wherein the filling bag with adjustable thermal insulation properties is connected to a side of the garment body close to the human body.

[0019] Preferably, the garment body comprises a fabric and a lining, the filling bag with adjustable warmth is located close to the back of the human body, the traction section extends between the fabric and the lining, and extends from the back of the human body through the shoulders to the chest of the human body.

[0020] Beneficial effects of the present invention:

[0021] The filling bag with adjustable thermal insulation of the present invention improves the local thermal insulation of clothing through the filling material inside the filling bag body, and adjusts the volume inside the filling bag body by using the adjustment ring attached to the filling bag body. When the traction section is pulled, the volume inside the filling bag body is reduced by contracting the adjustment ring, and the static air between the filling materials is discharged. At this time, the cold air from the outside and the heat of the human body can be conducted through the filling material with a higher thermal conductivity than the air, thereby achieving the effect of reducing the thermal insulation. When the traction section is relaxed, the filling material is reset under the action of its own elastic force, thereby increasing the internal volume of the filling bag body and opening the adjustment ring, so that the filling material can accommodate a large amount of static air after being dispersed, and the cold air from the outside is blocked from entering through the air layer with a lower thermal conductivity, and the heat loss of the body is prevented, thereby achieving the effect of improving the thermal insulation.

[0022] As described above, the wearer can adjust the warmth of the clothing steplessly according to his or her physical condition, changes in ambient temperature, and exercise intensity, meeting the wearer's diverse needs in different scenarios and greatly improving the convenience of travel.

[0032] The following will refer to Figures 1 to 3 to describe the heat-insulating adjustable stuffing bag and the heat-insulating clothing provided by the present invention.

[0033] Refer to Figure 1 , the heat-insulating clothing includes a clothing body 5 and a heat-insulating adjustable stuffing bag. Among them, the clothing body 5 includes a stitched fabric 51 and a lining 52, forming a cavity between the fabric 51 and the lining 52. The heat-insulating adjustable stuffing bag hangs down at the position of the lining 52 corresponding to the human back and is stitched to the lining 52. In some other embodiments, the heat-insulating adjustable stuffing bag can also be arranged at other positions, such as the position corresponding to the human waist or chest.

[0034] The heat-insulating adjustable stuffing bag is designed to adjust the heat insulation of the heat-insulating adjustable stuffing bag according to various factors such as the personal physical condition of the wearer, the environmental temperature, and the exercise intensity, so as to realize the adjustment of the heat insulation of the clothing body 5, thereby meeting the diverse heat insulation needs of the wearer in different scenarios and greatly improving the convenience of the wearer when traveling.

[0035] As above, hanging the heat-insulating adjustable stuffing bag at the position corresponding to the human back can facilitate the adjustment of the heat insulation at the back position, so as to solve the problem that the back generates a large amount of heat and it is not convenient to dissipate heat even when the clothing body 5 is opened. Therefore, the heat insulation at the back can be adjusted when the environmental temperature rises or the wearer exercises, improving the comfort. Further, in this embodiment, a plurality of heat-insulating adjustable stuffing bags are arranged in the vertical direction. Taking three as an example in this embodiment, the plurality of heat-insulating adjustable stuffing bags can ensure the heat insulation of the clothing body 5.

[0036] Refer to Figure 1 and Figure 2 , the heat-insulating adjustable stuffing bag includes a stuffing bag body 1 and a traction member 2. The stuffing bag body 1 hangs down inside the lining 52, and the inside of the stuffing bag body 1 is filled with filling material. The traction member 2 includes an adjustment section 21 and a traction section 22 arranged in sequence. One end of the traction member 2 is connected to the stuffing bag body 1. The adjustment section 21 fits along the circumference of the stuffing bag body 1 on the inner wall or outer wall of the stuffing bag body 1 to form an adjustment ring 211 sleeved outside the filling material. The traction section 22 extends from the back of the human body around the shoulder to the front chest position of the human body.

[0037] Based on the above, the warmth retention of the stuffing bag with adjustable warmth retention ensured by the stuffing is maintained, and the stuffing is limited by the adjusting ring 211. The size of the adjusting ring 211 is adjusted by the movement of the traction section 22. Refer to Figure 2 , when the wearer pulls the traction section 22, the adjusting ring 211 is contracted to reduce the internal volume of the stuffing bag body 1. At this time, the stuffing will gather together, and the static air between the stuffing is discharged. The cold air from the outside and the heat of the human body are conducted through the stuffing with a higher heat conduction coefficient than air, reducing the warmth retention. Refer to Figure 1 , when the wearer relaxes the traction section 22, it resets under the action of the self-elasticity of the stuffing. At the same time, the natural expansion and stretching of the stuffing bag body 1 are assisted by gravity. The internal volume of the stuffing bag body 1 increases, and a large amount of air enters and remains between the stuffing. At this time, the cold air from the outside is blocked by the air layer, and the heat of the body is prevented from dissipating, improving the warmth retention effect. During actual use, the stuffing can be quickly dispersed by patting or moving the stuffing bag body 1.

[0038] It should be added that when the stuffing bag body 1 expands only by relying on the stuffing itself without external force, the distance between two adjacent stuffing bag bodies 1 in the height direction is less than the height of a single stuffing bag body 1. Thus, after the wearer wears the clothing body 5, it is not easy to generate a gap between two adjacent stuffing bag bodies 1 to ensure the warmth retention. And the stuffing bag body 1 can shrink to a height less than the distance between two adjacent stuffing bag bodies 1 in the height direction, so that after the wearer wears the clothing body 5, a gap is generated between two adjacent stuffing bag bodies 1 for rapid heat dissipation.

[0039] Specifically, the stuffing bag body 1 is a rectangular piece of fabric that is folded in half along the center line in the width direction, and the three open sides are sewn to form a sealed cavity. And the long side position of the stuffing bag body 1 that is sewn is sewn to the lining 52 to fix the stuffing bag body 1. Compared with directly sewing with two layers of fabric, the folded area can have a smooth transition, which can not only improve the aesthetics and comfort. Of course, in some other embodiments, the stuffing bag body 1 can also be formed by directly sewing two layers of fabric.

[0040] Furthermore, the adjustment section 21 is arranged on the inner wall of the filling bag body 1, which can prevent the adjustment section 21 from contacting the components outside the filling bag body 1, achieving the effects of protecting the adjustment section 21 and enhancing the aesthetics. In this embodiment, an inner bag 3 is arranged inside the filling bag body 1, and the filling material is filled inside the inner bag 3, so that several scattered filling materials form a whole, and the adjustment ring 211 is sleeved outside the inner bag 3. Thus, when the adjustment ring 211 contracts, it first squeezes the inner bag 3, and by reducing the internal volume of the inner bag 3, the filling material is squeezed, so as to increase the acting area of the adjustment ring 211 and enhance the squeezing effect on the filling material, that is, the density of the filling material after being compressed is greater, thereby enhancing the range of warmth adjustment.

[0041] It should be noted that in some other embodiments, the adjustment section 21 can also be arranged on the outer wall of the filling bag body 1, and the filling material can be directly filled into the filling bag body 1.

[0042] Preferably, the filling material in this embodiment is down. The down clusters are in a flossy structure, and the floss branches have small three-dimensional structures, which can not only fix a large amount of air to enhance the warmth retention property, but also have good fluffiness and elasticity, and can quickly reset after the extrusion on the inner bag 3 is released, so as to enhance the warmth retention property of the filling bag body 1. In some other embodiments, the filling material can also be synthetic fiber or chemical fiber cotton.

[0043] Furthermore, a part of the adjustment section 21 extends out of the filling bag body 1 and is placed between the outer fabric 51 and the lining 52, while the traction section 22 extends from the cavity between the outer fabric 51 and the lining 52 around the back of the human body through the shoulder to the chest position of the human body. Thus, when the wearer pulls the traction section 22, the traction section 22 forms a fulcrum in the shoulder area, and uses the shoulder as a lever to change the direction of the force, so that it is convenient for the wearer to pull the traction section 22 downward to improve the pulling efficiency.

[0044] It is worth noting that in this embodiment, the adjustment section 21 is a metal wire with elasticity, and the traction section 22 is any one of the existing drawstrings. When the traction section 22 is released, the metal wire is in a natural state, and at this time, the internal volume of the inner bag 3 is the largest, that is, the warmth retention property of the inner bag 3 is the best at this time. After the traction section 22 is pulled, the metal wire deforms to squeeze the inner bag 3. After the traction section 22 is released, the metal wire will quickly reset under the action of its own elastic force, so that the internal volume of the inner bag 3 quickly increases. Preferably, the material of the adjustment section 21 in this embodiment is memory metal. After being deformed by an external force, the memory metal can restore its original shape only by unloading the stress without heating. This property is called "superelasticity" or "pseudoelasticity", such as materials like nickel-titanium alloy, so that the adjustment section 21 can quickly reset. Optionally, in some other embodiments, the adjustment section 21 can also be elastic cloth, and the width of the elastic cloth is not limited.

[0045] It should be added that in some other embodiments, the traction member 2 may also be integrally provided, that is, an entire pull cord is used to replace the adjustment section 21 and the traction section 22.

[0046] Referring to Figure 1 and Figure 3 , in order to guide and limit the movement of the adjustment section 21 to reduce the offset of the adjustment section 21, a limiting channel 4 is provided along the movement path of the adjustment section 21 on the side wall of the filling bag body 1, and at least part of the adjustment section 21 is disposed inside the limiting channel 4. Specifically, a guiding strip 41 is connected to the inner wall of the filling bag body 1, and both sides in the length direction of the guiding strip 41 are sutured to the side wall of the filling bag body 1, so as to form a limiting channel 4 between the guiding strip 41 and the side wall of the filling bag body 1. Thus, the adjustment section 21 is guided and limited through the limiting channel 4. Optionally, in some other embodiments, the guiding strip 41 may also be glued to the side wall of the filling bag body 1.

[0047] In addition, both sides in the length direction of the guiding strip 41 are in sealed cooperation with the inner wall of the filling bag body 1, so that the limiting channel 4 is isolated from the inner cavity of the filling bag body 1, to prevent the adjustment section 21 from rubbing against the inner bag 3 relatively, and also prevent the down from running, leaking and drilling.

[0048] It should be noted that in some other embodiments, the limiting channel 4 may also be formed by suturing a plurality of segmented limiting tubes to the inner wall of the filling bag body 1.

[0049] The filling bag with adjustable warmth retention further includes an auxiliary expansion mechanism, which is configured to expand the internal volume of the filling bag body 1. The auxiliary expansion mechanism may be a plurality of elastic members, such as springs. The two ends of the springs are fixedly connected to the inner wall of the filling bag body 1, so that after the traction section 22 is released, the filling bag body 1 can be expanded by the elastic force of the springs, so that the filling bag body 1 expands rapidly.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
