Abstract

Official abstract text for this publication.

A child seat detachably installable on a child stroller apparatus includes a seat frame including a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat, a side coupling part fixedly connected with the first frame portion and pivotally connected with the second frame portion, a tray connected pivotally with the side coupling part, a tray latch assembled with the side coupling part and operable to engage with the tray for locking the tray in a deployed position for use, and a linking member operatively connected with the tray latch and the second frame portion. A rotation of the second frame portion for collapsing the child seat causes the linking member to move for urging the tray latch to disengage from the tray.

First claim

Opening claim text (preview).

What is claimed is: 1. A child stroller apparatus comprising: a first and a second leg portion; and a child seat supported on the first and second leg portions, wherein the child seat includes a seat frame and a tray assembled with each other, the seat frame including: a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat; a side coupling part fixedly connected with the first frame portion, the side coupling part being respectively connected pivotally with the second frame portion and the tray, the tray being thereby rotatable relative to the side coupling part between a deployed position for use and a collapsed position; a tray latch assembled with the side coupling part, the tray latch being operable to engage with the tray for locking the tray in the deployed position for use; and a linking member operatively connected with the tray latch and the second frame portion, wherein a rotation of the second frame portion for collapsing the child seat causes a movement of the linking member that urges the tray latch to disengage from the tray so that the tray is unlocked and is movable relative to the side coupling part and the tray latch between the deployed position and the collapsed position. 2. The child stroller apparatus according to claim 1 , wherein the second frame portion has a cam surface, and the linking member is in sliding contact with the cam surface. 3. The child stroller apparatus according to claim 2 , wherein the child seat further includes a first spring respectively connected with the linking member and the side coupling part, the first spring biasing the linking member in a direction for keeping the linking member in sliding contact with the cam surface and urging an unlocking displacement of the tray latch. 4. The child stroller apparatus according to claim 2 , wherein the second frame portion is fixedly connected with a coupling shell that is pivotally connected with the side coupling part, and the cam surface is provided at an inner side of the coupling shell, the cam surface being movable in unison with the coupling shell. 5. The child stroller apparatus according to claim 1 , wherein the tray latch is pivotally connected with the side coupling part and is fixedly connected with a pin, and the linking member has a guide slot in which the pin is slidably and pivotally received. 6. The child stroller apparatus according to claim 1 , wherein the tray is rotatable about a pivot axis relative to the side coupling part, and the tray latch is pivotally connected with the side coupling part at a location offset from the pivot axis. 7. The child stroller apparatus according to claim 6 , wherein a side of the tray is fixedly connected with a protrusion having a notch disposed eccentric from the pivot axis, and the tray latch engages or disengages the notch for locking or unlocking the tray. 8. The child stroller apparatus according to claim 6 , wherein the child seat further includes a second spring respectively connected with the tray latch and the side coupling part, the second spring rotationally biasing the tray latch for locking engagement with the tray. 9. The child stroller apparatus according to claim 1 , wherein the first leg portion is provided with a seat mount, and the child seat is detachably fastened to the seat mount. 10. The child stroller apparatus according to claim 9 , wherein the child seat further includes: a connector pivotally connected with the side coupling part, the connector being engaged with the seat mount for fastening the child seat on the child stroller apparatus, and disengaged from the seat mount for removal of the child seat from the child stroller apparatus, the seat frame being rotatable relative to the connector for converting the child seat between multiple configurations of use; a latch operable to rotationally lock the seat frame with respect to the connector; and a release button operable to urge an unlocking displacement of the latch. 11. The child stroller apparatus according to claim 1 , wherein the child seat is slidable along the first leg portion. 12. The child stroller apparatus according to claim 11 , further including: a handle frame having a side segment that is coupled with the first leg portion via a pivot connection; and a linkage respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion. 13. The child stroller apparatus according to claim 12 , wherein a rotation of the handle frame relative to the first leg portion for unfolding the child stroller apparatus causes the child seat to slide along the first leg portion toward the pivot connection, and a rotation of the handle frame relative to the first leg portion for collapsing the child stroller apparatus causes the child seat to slide along the first leg portion away from the pivot connection. 14. The child stroller apparatus according to claim 12 , wherein the linkage has an elongate shape, the pivot connection being displaced from a first side of the linkage to a second side of the linkage opposite to the first side when the child stroller apparatus is switched from an unfolded state for use to a collapsed state. 15. The child stroller apparatus according to claim 11 , wherein the child stroller apparatus has a collapsed state and an unfolded state for use, the child seat is in a first position on the first leg portion in the unfolded state and in a second position on the first leg portion in the collapsed state, and the first leg portion is further assembled with an impeding part having a pass and a blocking state, the pass state allowing sliding movement of the child seat past the impeding part as the child stroller apparatus is switched between the collapsed and unfolded state, and the blocking state preventing movement of the child seat from the second position to the first position. 16. The child stroller apparatus according to claim 1 , further including a base frame provided with a plurality of wheels, the first and second leg portions being further pivotally connected with the base frame. 17. A child seat detachably installable on a child stroller apparatus, comprising: a seat frame including a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat; a side coupling part fixedly connected with the first frame portion and pivotally connected with the second frame portion; a tray connected pivotally with the side coupling part, the tray being thereby rotatable relative to the side coupling part between a deployed position for use and a collapsed position; a tray latch assembled with the side coupling part, the tray latch being operable to engage with the tray for locking the tray in the deployed position for use; and a linking member operatively connected with the tray latch and the second frame portion, wherein a rotation of the second frame portion for collapsing the child seat causes a movement of the linking member that urges the tray latch to disengage from the tray so that the tray is unlocked and is movable relative to the side coupling part and the tray latch between the deployed position and the collapsed position. 18. The child seat according to claim 17 , wherein the second frame portion has a cam surface, and the linking member is in sliding contact with the cam surface. 19. The child seat according to claim 18 , further includi
