Description

Technical Field

[0001] The present invention relates to the technical field of down jackets, in particular to a down jacket with a split airbag structure. Background Art

[0002] Down jackets are commonly used in winter and are mainly used to keep warm. Most existing down jackets are ventilated through the fabric or through the collar and hem, and the ventilation and air permeability is average. In addition, the size of existing down jackets is generally fixed and the tightness cannot be adjusted (the down jacket sticks to the person's body). When people wear down jackets and feel hot due to strenuous exercise or rising temperatures at noon, the down jackets cannot dissipate the heat quickly, resulting in poor wearing comfort. Summary of the Invention

[0003] The purpose of the present invention is to provide a down jacket with a split airbag structure to solve the problem raised in the above background technology that when people wear down jackets that are hot due to strenuous exercise or rising temperatures at noon, the down jacket cannot dissipate heat quickly, resulting in poor wearing comfort of the down jacket.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a down jacket with a split airbag structure, comprising: a down jacket body, a first airbag and a second airbag respectively provided on the inner back and waist of the down jacket body, and two sets of airbag assemblies provided on the inner chest of the down jacket body, the two sets of airbag assemblies being symmetrically distributed on both sides of the down jacket body placket;

[0005] The airbag assembly includes several groups of third airbags extending downward and interconnected. A switch is provided on the side wall of the third airbag near the armpit side of the down jacket body. A ventilation hole is opened under the armpit of the down jacket body. A zipper is provided on the ventilation hole for controlling the opening and closing of the ventilation hole and the switch. Pulling the zipper opens the ventilation hole and also opens the switch, so that the gas inside the third airbag is discharged from the ventilation hole, and the third airbag shrinks.

[0006] Preferably, the switch includes a mounting piece installed on the third airbag, an exhaust port connected to the third airbag is opened through the mounting piece, a blocking piece for blocking the exhaust port and an elastic piece connected to the blocking piece are slidably provided on the mounting piece, and a connecting piece is provided between the blocking piece and the zipper.

[0007] Preferably, there are several groups of the first airbags, and the groups of the first airbags are spaced apart on the inner back side of the down jacket body.

[0008] Preferably, the down jacket body is provided with an elastic rope for tightening the lower edge of the down jacket body and a fixing piece for fixing the elastic rope;

[0009] Wherein, a shoulder strap is provided on the inner back side of the down jacket body.

[0010] Preferably, the elastic cord is provided with a plurality of receiving components for supplying air to the interior of the second airbag or receiving the air inside the second airbag, and the plurality of receiving components are sequentially arranged along the length direction of the elastic cord;

[0011] Wherein, the second airbag is a strip-shaped airbag arranged transversely.

[0012] Preferably, the storage assembly includes a storage airbag provided on an elastic rope and connected to the second airbag, and the elastic rope is provided with a pressing member for pressing the storage airbag.

[0013] Preferably, the second airbag is wrapped with a mesh fabric, and a support airbag is connected to the side of the second airbag facing the human body;

[0014] Wherein, the volume of the supporting airbag is smaller than the volume of the second airbag.

[0015] Preferably, the first airbag, the second airbag and the third airbag can be detachably mounted on the down jacket body.

[0016] Compared with the prior art, the beneficial effects of the present invention are: in the present application, when the zipper is pulled, the ventilation port is opened, and when the zipper moves at the same time, the blocking member moves to open the exhaust port, so that the gas inside the third airbag is discharged from the ventilation port. After the gas inside the third airbag is discharged, it will shrink itself, so that a gap is generated between the down jacket body and the human body, so that the down jacket body can be worn more loosely, which is convenient for quickly dissipating the heat inside the down jacket body, thereby improving the overall breathability of the down jacket.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1 A down jacket with a split airbag structure comprises: a down jacket body 1, a first airbag 2 provided on the inner side of the back of the down jacket body 1, and a second airbag 4 provided on the inner side of the waist of the down jacket body 1; two sets of airbag assemblies provided on the inner side of the chest of the down jacket body 1, and the two sets of airbag assemblies are symmetrically distributed on both sides of the placket of the down jacket body 1;

[0025] Among them, see Figure 1 The airbag assembly includes several groups of third airbags 6. The third airbags 6 are long and vertically arranged. Several groups of third airbags 6 on the same side are connected to each other. A switch 8 is connected on the side wall of the third airbag 6 near the armpit side of the down jacket body 1. A ventilation hole 7 is opened under the armpit of the down jacket body 1. A zipper is provided on the ventilation hole 7 to control the opening and closing of the ventilation hole 7; and the zipper is connected to the switch 8. Specifically,

[0026] See also Figure 2 The switch 8 includes a mounting member 81, which is mounted on the third airbag 6 (the mounting member 81 is mounted on the third airbag 6 near the armpit side of the down jacket body 1), and an exhaust port 82 is opened through the mounting member 81, and the exhaust port 82 is connected to the third airbag 6; a blocking member 83 is slidably provided on the mounting member 81 for blocking the exhaust port 82, and an elastic member 84 is installed between the mounting member 81 and the blocking member 83 (to prevent the blocking member 83 from moving automatically), and a connecting member 85 (such as a connecting rope) is provided between the blocking member 83 and the zipper.

[0027] In this embodiment, as a further optimization solution, please refer to Figure 1 The first airbag 2, the second airbag 4 and the third airbag 6 can all be detachably installed on the down jacket body 1 (for example, the first airbag 2, the second airbag 4 and the third airbag 6 are installed on the down jacket body 1 by using Velcro); so that the first airbag 2, the second airbag 4 and the third airbag 6 can all be removed.

[0028] It should be noted that when people are hot, they pull the zipper to open the ventilation port 7, so that the down jacket body 1 is connected to the outside world, and the heat inside the down jacket body 1 is dissipated through the ventilation port 7; at the same time, when the zipper moves, it will pull the connecting piece 85, so that the blocking piece 83 moves to open the exhaust port 82 (that is, the switch 8 is opened); the gas inside the third air bag 6 is discharged from the ventilation port 7, and the gas inside the third air bag 6 will shrink after being discharged, so that a gap is generated between the down jacket body 1 and the human body, so that the down jacket body 1 is relatively loose when worn, which is convenient for ventilation and heat dissipation.

[0029] In this embodiment, as a further optimization solution, please refer to Figure 1 The third airbag 3 is connected to an inflation facility (small in size, such as an air pump) for inflating the interior of the third airbag 6.

[0030] In this embodiment, as a further optimization solution, please refer to Figure 1 There are several groups of first air bags 2, and several groups of first air bags 2 are arranged at intervals on the inner back of the down jacket body 1; the gaps between the several groups of first air bags 2 can allow gas to flow, thereby improving the efficiency of gas exchange between the inside of the down jacket body 1 and the outside world, and increasing the ventilation and heat dissipation ability of the down jacket body 1.

[0031] Example 2

[0032] As an optimized solution, see Figure 1 The down jacket body 1 is provided with an elastic cord 9 (the elastic cord 9 is installed inside the lower side edge of the down jacket body 1, and the end of the elastic cord 9 extends to the outside of the down jacket body 1), and the down jacket body 1 is provided with a fixing piece 10, and the end of the elastic cord 9 passes through the fixing piece 10; the elastic cord 9 is pulled to pull the end of the elastic cord 9 toward the outside of the down jacket body 1, so that the elastic cord 9 is tightened, and the moved elastic cord 9 is fixed by the fixing piece 10; the tightening of the elastic cord 9 will tighten the lower side edge of the down jacket body 1; when the elastic cord 9 is loosened, the lower side edge of the down jacket body 1 will be loosened; in relatively cold conditions, the lower side edge of the down jacket body 1 can be tightened to make the down jacket body 1 fit closely to the human body; in relatively hot conditions, the lower side edge of the down jacket body 1 can be loosened to create a gap between the down jacket body 1 and the human body, thereby improving the breathability of the down jacket body 1.

[0033] In this embodiment, as a further optimization solution, please refer to Figure 1 A shoulder strap 3 is provided on the inner side of the back of the down jacket body 1; the shoulder strap 3 is used so that people can carry the down jacket body 1 on their back after taking it off.

[0034] In this embodiment, as a further optimization solution, please refer to Figure 1 and Figure 3The second airbag 4 is a strip-shaped airbag arranged transversely; a plurality of storage components are provided on the elastic rope 9, and the plurality of storage components are arranged in sequence along the length direction of the elastic rope 9;

[0035] Among them, see Figure 3 and Figure 4 The storage component includes a storage airbag 11 provided on the elastic rope 9, and the storage airbag 11 is connected to the second airbag 4; a pressing piece 12 is provided on the elastic rope 9, and there are two pressing pieces 12, which are located on both sides of the storage airbag 11 and are used to press the storage airbag 11.

[0036] It should be noted that when the lower edge of the down jacket main body 1 is tightened, the elastic rope 9 is stretched. At this time, the distance between the two pressing parts 12 is larger, so that the pressing part 12 does not squeeze the storage air bag 11 (or the squeezing amplitude is smaller); when the lower edge of the down jacket main body 1 is relaxed (under hotter conditions), the elastic rope 9 is not stretched. At this time, the distance between the two pressing parts 12 is smaller, so that the pressing part 12 squeezes the storage air bag 11, and squeezes the gas inside the storage air bag 11 into the inside of the second air bag 4, thereby increasing its expansion amplitude; the lower side of the down jacket main body 1 is separated from the human body, so that there is a gap between the lower side of the down jacket main body 1 and the outside world, thereby increasing the breathable and heat dissipation capacity of the down jacket main body 1.

[0037] In this embodiment, as a further optimization solution, please refer to Figure 1 The second airbag 4 is wrapped with a mesh fabric; the side of the second airbag 4 facing the human body is connected to a support airbag 5, and the volume of the support airbag 5 is smaller than that of the second airbag 4; when the gas inside the storage airbag 11 is squeezed into the inside of the second airbag 4, the support airbag 5 will expand and bulge toward the human body; it is used to reduce the contact area between the second airbag 4 and the human body, increase the gap between the down jacket main body 1 and the human body, and further improve the breathability and heat dissipation capacity of the down jacket main body 1.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
