Abstract

A children's wagon comprising a wagon body, a bottom wall, and front and rear bolsters secured to the bottom wall. The front bolster is pivotally secured to the bottom wall and a pin is associated with the bottom wall and is adapted to extend downwardly therefrom to interfere with the front bolster movement to thereby minimize the possibility of tipping of the wagon. The pin is adapted to be moved upwardly out of interfering position whereby the front bolster can be moved 180° in either direction to thereby place the wagon in more convenient positions for transportation and storage. The front and rear bolsters are each provided with shock absorbers positioned above the front and rear axles adjacent each of the wagon wheels. Slotted vertically extending extensions on each side of each bolster receive the wagon axles and provide for vertical movement of the bolsters relative to the axles. The bolsters move in opposition to springs which are located in surrounding relationship with the respective slotted extensions. A bellows is, in turn, positioned around each spring and upper and lower retainers are provided for engagement with the respective ends of the springs and bellows.
