1. An automatically retracting cushioning device, formed by sticking two sheets of outer film, comprising:
a first air cylinder sheet, comprising a plurality of first air cylinders; a second air cylinder sheet, in air communication with the first cylinder sheet, and comprising a plurality of second air cylinders; a third air cylinder sheet, in air communication with the second air cylinder sheet, and comprising:
a plurality of third air cylinders;a plurality of retractable blocks, formed by sticking the two sheets of outer film together by means of hot sealing, a portion of each of the plurality of retractable blocks being unstuck to allow each of the plurality of retractable blocks to be in air communication with other ones of the plurality of retractable blocks and the plurality of third air cylinders, and positioned on one end of the plurality of third air cylinders; a width of each respective retractable block being smaller than a width of a corresponding third air cylinder, and the retractable blocks being arranged vertically and horizontally in a checkerboard pattern; anda triangle member formed by a portion of the third air cylinder sheet, having interior angles; a plurality of first bendable nodes, disposed between the first air cylinder sheet and the second air cylinder sheet, so that the second air cylinder sheet is bent toward the first air cylinder sheet along the plurality of first bendable nodes; and a plurality of second bendable nodes, disposed between the second air cylinder sheet and the third air cylinder sheet, so that the third air cylinder sheet is bent toward the second air cylinder sheet along the plurality of second bendable nodes, the first and the second bendable nodes causing the third air cylinder sheet and the first air cylinder sheet to be approximately perpendicular to the second air cylinder sheet, and the third air cylinder sheet to be approximately parallel to the first air cylinder sheet, and causing the third air cylinder sheet and the first air cylinder sheet to be located at different planes and respectively having a third projecting length and a first projecting length corresponding to a projecting axis parallel to the first and the third air cylinder sheet, wherein the third air cylinder sheet bends at where the plurality of retractable blocks is configured, a reduction of the interior angles of the triangle member leads the reduction of the third projecting length of the third air cylinder sheet, and an increase of the interior angles of the triangle member leads the increase of the third projecting length of the third air cylinder sheet, the interior angles of the triangle member and the length of third air cylinders are reduced when the third air cylinder sheet is pressed. |
