Abstract
An interconnected rotary system with built-in suspension is provided for baby prams, intended to provide a use of only two wheels with interconnected steering. This system consists of two rotary suspension blocks (2) supporting the wheels (1) fixed to the chassis on (X) with a suspension spring (5) inside the rotary block (2) and with the rotary points (Y) on which a steering bar (3) is articulated. This new system will allow the use of larger wheels, increasing both the baby and user's comfort.
Claims7
A steering and suspension system for front wheels of a baby pram having a chassis and front legs and front wheels, comprising:
- a pair of suspension blocks for supporting lower ends of the front legs and for supporting the front wheels, the suspension blocks each having a rotary point;
- an interconnection having ends attached to the rotary point of each of the suspension blocks and configured to interlockingly interconnect the suspension blocks together to provide that a steering of a first of the front wheels forces a parallel steering of a second of the front wheels;
- a tie located inside one of the front legs;
- and
- a sliding spring device connected to the tie,
- the sliding spring device operating under direction of the tie to act on a rim of the first wheel stopping the first wheel and, via the interconnection rod, stopping the second wheel.
