发明名称 Safety spreader bar lock for umbrella stroller
摘要 A foldable stroller includes a safety lock for maintaining the stroller in an unfolded use condition. The stroller comprises side frames which are connected together by scissor frames to move the side frames between open use positions and closed folded positions. To maintain the side frames in a spread use position, a two-part spreader bar is provided. A lock in the form of a spring loaded slide on one of the spreader bar parts includes a lock and guide pin which engages a detente in the other spreader bar part to maintain the spreader bar part in an aligned condition. This avoids an inadvertant folding of the stroller. To permit folding of the stroller this slide is pushed to the side disengaging the pin from the detente and permitting the spreader bar parts to be lifted. This allows the side frames to collapse toward each other resulting in the folding of the stroller.
