A fold joint for a stroller has a first latch part fixed to a first frame element and a second latch part fixed to a second frame element. The latch parts are pivotable relative to one another about a pivot axis between an in-use orientation and a folded orientation. A latch shuttle is movable between a latched position locking the latch parts in the in-use orientation and an unlatched position unlocking the latch parts. A latch pin is carried by the latch shuttle. A track on the first latch part has a fold portion and a latch portion. A slot on the second latch part aligns with the latch portion in the in-use orientation. The latch pin is captured within the track and slot. When the latch shuttle is moved to the unlatched position, the latch pin is moved along the latch portion to the fold portion of the track. When the latch parts are pivoted toward the folded orientation, the latch pin moves along the fold portion of the track.

1. A fold joint for a stroller comprising: a first latch part defining a first axis between opposing ends thereof, with one end fixed to a first frame element and the other end comprising:two plates extending parallel to the first axis and to each other, the plates including:pivot holes formed through a center portion of each plate, the pivot holes defining a pivot axis therethrough; anda track formed through at least one of the two plates, the track comprising:a linear latch portion radially spaced from the pivot axis and extending parallel to the first axis, andan arcuate fold portion extending from an end of the latch portion distal to the first frame element and defining a constant radius about the pivot axis; anda second latch part defining a second axis between opposing ends thereof, with one end fixed to a second frame element and the other end comprising:a substantially circular puck, wherein a lateral width of the puck is selected so as to fit between the parallel plates of the first latch part, the puck comprising:an opening formed through the width of the puck at a center thereof and extending perpendicular to the second axis, the opening configured to align with the pivot holes in the plates of the first latch part, such that a pivot pin can pass through the aligned holes and opening to allow relative pivoting between the first and second latch parts about the pivot axis;a latch bore formed through the width of the puck parallel to the second axis at a location radially offset from the opening, substantially aligned with the latch portion of the track, the latch bore further including a linear slot formed through the width of the puck extending perpendicular to the second axis; anda latch shuttle inserted into the latch bore, the latch shuttle including a latch pin extending perpendicularly therefrom and passing outwardly through the slot and the track;wherein the latch shuttle is movable between:a latched position, wherein the latch pin is engaged within the latch portion of the track, and a latching end of the latch shuttle is engaged with a latch receptacle formed in the first frame element, such that the first and second frame elements are locked against pivotal movement about the pivot axis; andan unlatched position, wherein the latch pin is moved into the fold portion of the track, and the latching end of the latch shuttle is disengaged from the latch receptacle, such that the latch pin is free to move along the fold portion of the track, thereby allowing pivotal movement between the first and second frame elements about the pivot axis. 2. A fold joint according to claim 1, wherein the first frame element is a front leg of a frame assembly of the stroller and wherein the second frame element is a push arm of a handle assembly of the frame assembly. 3. A fold joint according to claim 1, wherein the track formed on the one of the two plates is a first track, and other of the two plates comprises a second track substantially mirroring the track formed on the one plate, and wherein the latch in extends through both tracks. 4. A fold joint according to claim 1, wherein the latch shuttle is resiliently biased toward the latched position. 5. A fold joint according to claim 1, further comprising: a cover that encloses and hides portions of the first and second latch parts including the latch pin, the track, the slot, and the latch shuttle.
