Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention is related to the structure of a duvet.

(b) Conventional technology Unlike ordinary futons, duvets are made by dividing the space between the outer fabric and the lining fabric into several small rooms, and storing the down feathers in the small rooms. The direction was parallel to the sides of the futon both vertically and horizontally.

(c) Problems to be solved by the invention Feather storage compartments that are rectangular or square in shape and whose dividing lines are parallel to the vertical or horizontal sides of the futon cover may cause the down storage compartment to be damaged by constant vibration or movement during sleep. In the room, the feathers moved from one end to the other and were bunched together, leaving a part without feathers at the other end of the feather storage compartment, which had a negative effect on the heat retention function of the duvet. .

(d) Technological means to solve the problem A partition line 4 formed by directly sewing or adhering the outer fabric 1 and the lining fabric 2, or the upper end of the horizontally long side of the band-shaped partition fabric 4 is connected to the outer fabric 1. The space formed between the front and lining fabrics 1 and 2 of the futon is reduced by the wall of the partitioning fabric 4, which is formed by integrating the lower end of the partitioning fabric 4 with the lining fabric 2 by means such as sewing or gluing. In partitioning the room, an appropriate number of approximately diamond-shaped down storage compartments 5 are provided by several strips of partition line or partition cloth 4 set to be diagonal rather than parallel to the sides of the futon. The structure of the duvet is characterized by:

In the above, the partition line or the partition cloth 4 can be bonded by directly applying a resin glue or the like to the desired bonding location, or by interposing a tape having a hot-melt resin glue layer on both sides between the desired bonding locations. The resin glue layer is melted to a bondable state by applying heat and pressure from above and below, and is cured again to completely bond the desired location.

(e) Function of the invention The invention has the above structure, and a force is always acting on the feathers to restore their shape to the maximum size.

In addition, the tube, which is narrower at the outlet than the thickness in the middle, slows down the flow rate of water at the outlet, so the approximately diamond-shaped feather storage compartment 5 becomes thinner in all directions on the four sides of the futon. There is. Therefore, even if the feathers try to move in either direction within the feather storage compartment 5, the restoring force unique to the feathers and the feather storage that gradually becomes thinner and in a direction different from the line of the sleeper's body are maintained. The shape of the small chamber 5 acts to prevent the feathers from moving and prevent the feathers from shifting.

(f) Effects of the invention Therefore, compared to conventional futons with square or rectangular feather storage compartments, the feathers of the duvet of the present invention do not shift in one direction even if vibrations occur continuously in one direction during sleep. Since there are no feathers, the feathers are always evenly distributed in the futon's down storage compartment 5, and the heat retention effect is not diminished, so this is an extremely useful device for use as a duvet.
