Registered Utility Model No. 3091161 (see FIGS. 1 to 4)

  In the cocoon child of the above-mentioned patent document 1, although moisture in the indentation can be effectively eliminated, the bedding itself is not good because the air permeability is poor between the bedding and the upper surfaces of a large number of horizontal plate parts constituting the cocoon child body. When moisture is contained, wrinkles and the like may occur in the portion, and there is room for improvement.

  In view of the above-mentioned situation, the present invention intends to provide a kite that can improve the air permeability between the bedding and the kite but can suppress a decrease in strength as much as possible. It is in.

In order to solve the above-mentioned problems, the present invention includes a support portion for connecting a large number of horizontal plate portions that are arranged in parallel at predetermined intervals in the left-right direction and for placing and supporting the horizontal plate portions. A plurality of ventilation holes penetrating in the vertical direction in all or a part of the plurality of horizontal plate portions, and each hole is formed from the upper surface of the bedding to the vertical thickness of the horizontal plate portion. A first hole formed in substantially the same size up to a set depth position located above half, and the first hole formed in a range from the lower end of the first hole to the lower end surface of the horizontal plate portion. A second hole having a size smaller than one hole, and the support portion is composed of a plurality of pedestals attached to specific positions in the left-right direction of the horizontal plate portion, and the horizontal plate portion is formed on the upper surface of the pedestal. For guiding air from the hole to the outside of the pedestal in communication with the hole formed in It is characterized in that the formed part.
Therefore, while securing a large amount of non-contacting portions with the bedding on the large first hole on the side in contact with the bedding, air is moved and guided downward in the second hole smaller than the first hole, so that the bedding and the horizontal plate The air permeability in the contact portion with the portion can be ensured satisfactorily .

  A plurality of the left and right holes are arranged in a row at predetermined intervals, and are arranged in a row, and a plurality of left and right guide grooves of the pedestal are located almost immediately below the holes arranged in the row. You may comprise from a groove part long in a direction.
