Claims

[Scope of utility model registration request]

A stepladder in which a pair of front and rear ladders are pivotally connected to each other at their upper ends so as to be freely openable and closable, and a top plate is attached to the upper end of the ladder, and a front plate is attached to the top plate so as to be rotatable. ,
The upper ends of a pair of ladders are rotatably supported by support shafts on the left and right side plates of the top plate, and a horizontal shaft is provided on the upper end of the other ladder, and the support shafts are provided on the side plates. An arc-shaped guide groove centered on the shaft and a horizontal engagement groove continuous from the lower end of the guide groove to the side opposite to the support shaft are provided, and the horizontal shaft is inserted into the guide groove and the engagement groove. The front plate is fitted so as to be slidable, and the front plate is pivotally mounted at approximately the middle portion of the side plate in the front-back direction so as to be rotatable in the vertical direction by a connecting body extending from the back surface of the front plate.
The opening/closing legs of the pair of ladders allow the top plate to rotate horizontally and directly about the support shaft, respectively, and the front plate is connected by each rotation of the top plate when the legs are closed or opened. A stepladder in which the front plate is rotatable from a collapsed state to an upright state by pressing and releasing the pressure on the horizontal axis.
