Document Type and Number:
Japanese Patent JP2012081238
Kind Code:
A
Abstract:

To provide a folding type structure of high durability.

The folding type structure includes main frames which are divided at the center and also pivotally-attached in a foldable state and bents which are pivotally-attached to the individual main frames and have each an upper cylindrical part extending in the downward direction and a lower cylindrical part capable of varying the positional relation in the vertical direction with the upper cylindrical part. The upper cylindrical part has a caster fixed in the lower portion and has a longitudinal-hole-shaped hole portion extending in the vertical direction, while the lower cylindrical part moves in the vertical direction, responding to the movement of a pin inserted into the hole portion, which is made in the vertical direction of the hole portion, and the positional relation in the vertical direction between the caster and the lower portion of the lower cylindrical part varies therewith. The pin comes into contact with the main frame and moves in the vertical direction, responding to a state of inclination of the main frame.
