【考案の詳細な説明】 本考案は、回転ドアや引き戸等の扉体の構造に
関するものである。[Detailed Description of the Invention] The present invention relates to the structure of a door body such as a revolving door or a sliding door.

従来、この種の扉体は、収納棚付電話台、ロツ
カー、台所用品収納箱等に多く使用されている
が、そのほとんどが、たとえば、薄い金属板等の
一枚板を折曲して出来ているため、強度が十分に
保ち得ず、製造時に変形が生じたり扉体の開閉に
よつて歪みが生じやすかつた。 Conventionally, this type of door body has been widely used for telephone stands with storage shelves, lockers, kitchen utensil storage boxes, etc., but most of them are made by bending a single plate such as a thin metal plate. Because of this, it was not possible to maintain sufficient strength, and deformation occurred during manufacturing, and distortion occurred easily when the door body was opened and closed.

著しく、扉体の開閉時にガタを生じる等の欠陥が
あつた。 In addition, the hinge part of the door body is subjected to particularly strong repeated stress, and the wear and tear on this hinge part increases significantly as the door body opens and closes. Mounting holes were provided in the upper and lower horizontal plates of the door body made of a single sheet of thin steel, and the hinge shaft protruding from the attached part of the door body was inserted into these holes. The parts were easily damaged, showed significant wear and distortion, and had defects such as rattling when the door was opened and closed.

本考案は、前記欠陥を解消すべく、その目的と
するところは、堅牢で、かつ扉体の開閉によつて
生ずる歪みを少なくするとともに、扉体のヒンジ

ものも含む。 At one of the left and right side edges of the upper and lower horizontal frames 4 and 5 (in this embodiment, the left side edge as shown in FIGS. 1 to 3),
An extending portion 24 is formed in the lower horizontal frames 4, 5 and extends in the longitudinal direction (leftward in this embodiment). The extension portion 24 has the same width in the vertical direction as the front vertical portions 4b, 5b of the upper and lower horizontal frames 4, 5, and is an extension of the front vertical portions 4b, 5b. If necessary, it may be extended along with the bottom plates 4a and 5a to maintain sufficient strength, and the vertical width of the extended portion 24 may be made smaller than the front vertical portions 4b and 5b for strength or processing reasons. It can be made larger or smaller as needed. The tip of the extending portion 24 is bent into a small cylindrical shape to form a cylindrical portion 26.
A vertical mounting hole 27 of an appropriate length is formed at the axial center of the shaft 6. Attachment hole 27 of this cylindrical part 26
In this case, a hinge shaft 25a that projects vertically downward or vertically upward is inserted from the door body attachment part 25, and a boss part 28 is also formed on the outer surface of the cover plate 18 opposite to this mounting hole 27. An insertion hole 29 is provided to protrude and pass through the axial center of the boss portion 28 . The boss portion 28 is provided to prevent the upper and lower surfaces of the door body 1 from coming into contact with the door body attached portion 25 during opening and closing. Further, the diameter of the insertion hole 29 is slightly larger than the diameter of the attachment hole 27 of the cylindrical portion 26. Therefore, the door body 1 can be rotatably attached to the door body attachment portion 25 via the hinge shaft 25a inserted through the insertion hole 29 and the attachment hole 27. Note that the cylindrical portion 26 mentioned herein does not have to have a shape with a completely closed peripheral wall, but also includes one that is bent with a gap to the extent that the hinge shaft 25a cannot be disengaged from the fitting.
