  • Patent number: 8590919
    Abstract: A stroller frame is disclosed and includes a front-leg support member, a rear-leg support member, an upper support member, and a connection device which connects the front-leg support member, the rear-leg support member, and the upper support member respectively, such that the rear-leg support member and the upper support member can rotate relative to a first rotation axis and the front-leg support member and the rear-leg support member can rotate relative to a second rotation axis. Thereby, the invention uses just the integrated connection device to fold the three support members smoothly, which solves the problem that a foldable stroller in the prior art usually realizes the folding by a pivot device which rotates two of support members thereof so as to drive the other support members but is accompanied by the difficulty in reducing the length of the folded stroller.
