摘要： A foldable two seat face-to-face tandem baby carriage includes a pair of wheeled front legs, a pair of wheeled rear legs, and, two pairs of horizontal longitudinal bars extending between the legs. A U-shaped push handle connects pivotally with the rear of the upper bars, and the free ends of the push handle substantially abut the rear legs about midway along the length. Locking means interengage the push handle with the legs in the extended position and bars in the horizontal position to provide a tandem seating construction with seats and backrests facing each other. Folding is effected when the backrests are parallel and an additional locking slot is provided in a support for anchoring the forward backrest in the parallel position. Release of the lock by foot pressure on a transverse bar extending between the rear legs causes the push handle to move downwardly and forwardly and the two legs to collapse and fold towards each other to be substantially parallel with the push handle in the folded position. The two sets of parallel longitudinal bars collapse to be substantially parallel and towards each other in the folded position. A single action permits folding and unfolding of the tandem carriage.

摘要： A foldable tandem seat baby carriage including a pair of wheeled front legs, a pair of wheeled rear legs, and, in the operative position, two pairs of horizontal longitudinal bars extending between the legs. A U-shaped push handle connects pivotally with the rear of the upper bars, and the free ends of the push handle substantially abut the rear legs about midway along their length. Locking means interengage the push handle with the rear legs in the extended position and bars in the horizontal position to provide tandem multiple seat construction. Release of the lock by foot pressure on a transverse bar extending between the rear legs causes the push handle to move downwardly and forwardly and the two legs to collapse and fold towards each other to be substantially parallel with the push bar in the folded position. The two pairs of parallel longitudinal bars collapse to be substantially parallel towards each other in the folded position. A single action thereby permits folding of the tandem carriage into the folded position. From a folded position, a similar single action provides unfolding to the extended position.

摘要翻译： 一种可折叠的串联座椅婴儿车，其包括一对轮式前腿，一对轮式后腿，并且在操作位置处，在腿之间延伸的两对水平纵向杆。 U形推柄与上杆的后部枢转地连接，并且推动手柄的自由端在其长度的大约中间部分基本上抵靠后腿。 锁定装置将推动手柄与延伸位置的后腿和水平位置的杆互相接合，以提供串联多座椅结构。 通过脚部压力在后腿之间延伸的横向杆上的锁释放使得推动手柄向下和向前移动，并且两个腿彼此折叠并折叠成在折叠位置与推杆大致平行。 两对平行的纵向条在折叠位置处折叠成彼此基本平行。 因此，单个动作允许串联托架折叠到折叠位置。 从折叠位置，类似的单一动作提供展开到延伸位置。
