Abstract: A folding frame for a tricycle, scooter or child's bicycle has a front frame part on which the front wheels can be mounted and a rear frame part on which the rear wheels can be mounted. A swivelling joint with a front articulated part is mounted on the front frame part and a rear articulated part is mounted on the rear frame part. The first of the two articulated parts has a first recess and the second of the two articulated parts has a second and third recess. The first recess and the second recess are in alignment in the use position of use and the first recess and the third recess are aligned in the folded position. The first articulated part and the second articulated part are locked against one another in the use position and in the folded position via a pin which can be moved in the recesses.
