Folding frames for children's or dolls' prams essentially have two front and two rear stays crossed scissors-fashion which are secured to bearing stays. The variable lower pivot points of the front and rear stays, however, lead to a highly unstable system also subject to mechanical stresses, while the crossing point of the front and rear stays results in reductions in their cross-section. A solution to this problem is found in that the stays (1, 2) are hinged on immovable pivot points (7) on connecting stays (10) in the lower region and in the central region there is, at the crossing point of the stays (1, 2), a connecting component (4) having a bush (6) arranged to be movable along one of the two stays (1, 2), the bush (6) being connected to a pivot (5) in the central region of the other stay (1, 2). |
