摘要：A door body formed largely of yieldable material has two panels spaced apartwith a hollow separator between them that is rectangular in cross section and has twopairs of oppositely disposed sides and two dividers therein at right angles to each otherthat thereby provide four enclosed openings. This construction holds the paneledportion of the door body firm, especially at the outer edges, yet is flexible enough topermit some distortion when the door is forcibly opened as by striking it vigorously witha moving truck.
