ATTACHMENT METAL FITTING FOR HOLLOW STRUCTURE

Japanese Patent JP2023080384

A

To realize an attachment metal fitting for a hollow structure which enables easy attachment to or detachment from a hollow structure and can be preferably used.SOLUTION: An attachment metal fitting 100 for a hollow structure can be switched to an attitude, at which an attitude of an engagement piece 20 is along an axis direction of a shaft part 10 and the engagement piece 20 may be inserted into a through hole H of a hollow wall K, by switching a direction of the shaft part 10 so that a rotation restriction part 15 is disposed at an upper surface side of the shaft part 10 and a support shaft 30 is arranged substantially horizontally. Further, the attachment metal fitting 100 can be switched to an attitude, at which the attitude of the engagement piece 20 intersects with the axial direction of the shaft part 10 and the engagement piece 20 cannot be inserted into the through hole H of the hollow wall K, by switching the direction of the shaft part 10 so that the rotation restriction part 15 is disposed at a lower surface side of the shaft part 10 and the support shaft 30 is arranged substantially horizontally. The attachment metal fitting 100 for the hollow structure enables easy attachment to or detachment from the hollow wall K and can be used preferably.SELECTED DRAWING: Figure 1
