Child carriage with linkage for transitioning the child carriage to a folded configuration

A carriage for pushing a child carrier, the carriage comprising:

• a frame configured to transition between an expanded configuration and a folded configuration, the frame comprising:
• an upper end configured to removably couple to the child carrier;
• a first leg assembly comprising a first front leg and a first rear leg that are pivotably coupled to one another;
• a first linkage having a first link pivotably connected to the first front leg, and a second link that is pivotably connected to the first rear leg and the first link, the first linkage configured to guide movement of the first front leg and first rear leg as the frame is transitioned between the expanded and folded configurations;
• a second leg assembly comprising a second front leg and a second rear leg that are pivotably coupled to one another;
• and
• a second linkage having a first link pivotably connected to the second front leg, and a second link that is pivotably connected to the second rear leg and the first link of the second linkage, the second linkage configured to guide movement of the second front leg and second rear leg as the frame is transitioned between the expanded and folded configurations;
• a fold latch for each of the first and second linkages, each latch configured to releasably engage one or both of the first and second links of a respective one of the first and second linkages to prevent the first and second links of the respective one of the first and second linkages from pivoting relative to one another, wherein each fold latch is configured to transition between a locked position in which the first and second links of a respective linkage are not pivotable relative to one another and an unlocked position in which the first and second links of a respective linkage are pivotable relative to one another;
• a crosspiece extending from the first linkage to the second linkage, wherein each fold latch is transitioned from the locked position to the unlocked position in response to application of a force to the crosspiece;
• and
• a plurality of wheels attached to lower ends of the first and second leg assemblies.

• an upper end configured to removably couple to the child carrier;
• a first leg assembly comprising a first front leg and a first rear leg that are pivotably coupled to one another;
• a first linkage attached to the first front leg and the first rear leg so as to guide movement of the first front leg and first rear leg as the frame is transitioned between the expanded and folded configurations, the first linkage defining a first support surface that is configured to support an underside of the child carrier when the child carrier is coupled to the frame;
• a second leg assembly comprising a second front leg and a second rear leg that are pivotably coupled to one another;
• and
• a second linkage attached to the second front leg and the second rear leg so as to guide movement of the second front leg and second rear leg as the frame is transitioned between the expanded and folded configurations, the second linkage defining a second support surface that is configured to support an underside of the child carrier when the child carrier is coupled to the frame;
• wherein the first linkage includes a first link pivotably connected to the first front leg and a second link pivotably connected to the first rear leg, the first and second links being pivotably coupled to one another and the second linkage includes first link pivotably connected to the second front leg, a second link pivotably connected to the second rear leg, the first and second links of the second linkage being pivotably coupled to one another, the first and second links of the first linkage define the first support surface, and the first and second links of the second linkage define the second support surface;
• and
• a plurality of wheels attached to lower ends of the first and second leg assemblies.
