Abstract
A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets. Each of the bayonets has a linking portion connected pivotally to the driving mechanism of a respective one of the leg frames. For each of the leg frames, change of a distance between the first and second intersections of the driving mechanism and the legs during pivot action of the legs converts a position of the engagement unit relative to the legs.
Claims16
A foldable child carriage configured to support a child seat thereon, the foldable child carriage comprising:
- a frame having:
- a first pair of legs, including a first front leg and a first rear leg that are pivotably coupled to one another;
- a first car seat adapter configured to couple to the child seat, the first car seat adapter coupled to the first pair of legs by a first linkage such that, when the first front leg and first rear leg are pivoted relative to one another about a first pivot axis, the first linkage causes the first car seat adapter to move relative to the first pivot axis;
- a second pair of legs spaced from the first pair of legs, the second pair of legs including a second front leg and a second rear leg that are pivotably coupled to one another;
- and
- a second car seat adapter configured to couple to the child seat, the second car seat adapter coupled to the first pair of legs by a second linkage such that, when the second front leg and second rear leg are pivoted relative to one another about a second pivot axis, the second linkage causes the second car seat adapter to move relative to the second pivot axis;
- and
- a plurality of wheels attached to the frame.
