Description

Down jumper having fluid filter

The present invention relates to a down jumper, and more particularly, to a down jumper having a fluid filter having improved ventilation and drainage by installing a fluid filter at a plurality of points of the inner skin or the outer skin.

Down jumpers are a type of warm clothing filled with warm duck or goose down between the outer and inner skins. Down is a mixture of duck and goose necks and chest hair and feathers. Generally, the ratio of hair to feather is 4: 1 or 9: 1, and the higher the ratio of hair is, the lighter and warmer, the more hair is used.

Unlike the down, such down is not united, and because each one is independent, if the down jumper is worn for a long time, the down inside the down jumper will be concentrated down and hit down. In order to prevent this, the outer shell and the inner shell are sewn at the same time to separate the plurality of filling parts.

In this way, the down is filled in a plurality of down charging sections, and the flow of fluid (air, sweat, water for washing, etc.) into the down charging sections is limited to the surface of the seam, the outer shell, and the lining. There is a limit to entering and leaving effectively. In particular, in the case of the down jumper, the outer shell is waterproof, and since the fibrous structure is dense so that down does not fall to the outer surface of the outer shell or the inner skin, there is a limit to the smooth movement of the fluid through the outer surface of the outer shell and the inner skin.

Because of this, since the down charging part is poorly ventilated, sweat or dust, etc. that have entered the down charging part remain in the down charging part as it is, and the down may be easily contaminated or deteriorated by sweat or dust remaining in the down charging part.

In addition, since the water does not enter well into the down charging portion during washing of the down jumper, and the water does not fall out well, there is a problem in that the washability is degraded and it takes a long time to dry the washed down jumper.

Accordingly, it is an object of the present invention to provide a down jumper with a fluid filter that can prevent down from exiting out of the down packing while ensuring a smooth flow of fluid to the down packing.

Another object of the present invention is to provide a down jumper having a fluid filter capable of improving washability and drying after washing.

In order to achieve the above object, the present invention provides a down jumper comprising an outer shell, an inner, a down and a fluid filter. The inner shell is provided inside the outer shell to form a down filling part by sewing with the outer shell, and a plurality of filter holes are formed. The down is filled in the down charging part. The fluid filter is installed in the filter hole, and the fluid passes in and out of the down filling and the down filters.

In the down jumper according to the present invention, the fluid filter may be a mesh eyelet having a filter net in a central portion. The fluid filter may further include a cloth filter inserted into the filter network inside the endothelium.

In the down jumper according to the present invention, the fluid filter covers the filter hole inside the endothelial and includes a cloth filter sewn along the periphery of the filter hole.

In the down jumper according to the present invention, the density of the cloth filter is higher than the density of down charged in the down charging part.

In the down jumper according to the present invention, the cloth filter may be one of a raised fabric or a nonwoven fabric.

In the down jumper according to the present invention, the fluid filter may be installed at the endothelial portion corresponding to the edge portion of the down jumper.

In the down jumper according to the present invention, a plurality of filter holes may be formed in the envelope.

In the down jumper according to the present invention, by installing a fluid filter at a plurality of points of the endothelial or the outer skin, air moves smoothly into or out of the down charging part through the fluid filter, and the down is not discharged out of the down charging part. As such, since the fluid filter improves the ventilation of the down charging part, it is possible to minimize the contamination or alteration of the down due to the remaining of sweat or dust on the down charging part.

In addition, since water flows in and out smoothly through the fluid filter during washing of the down jumper according to the present invention, washing and drying property of the down jumper can be improved.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.
