Abstract

A child seat is detachably mounted on a foldable stroller comprising a stroller handle and front and rear leg portions. The stroller handle is foldably connected to the rear leg portion. The front leg portion is foldably connected to the rear leg portion and has a first adaptor. The child seat includes a first pivot and a seat frame having a lower seat portion and an upper seat portion foldably connected to the lower seat portion. The first pivot is pivotably connected to the lower seat portion and detachably mounted on the first adaptor. When the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

First claim

What is claimed is:

1. A child seat detachably mounted on a foldable stroller, the foldable stroller comprising a stroller handle, a front leg portion, and a rear leg portion, the stroller handle being foldably connected to the rear leg portion, the front leg portion being foldably connected to the rear leg portion and having a first adaptor, the child seat comprising:
a seat frame having an upper seat portion and a lower seat portion, the upper seat portion being foldably connected to the lower seat portion; and
a first pivot pivotably connected to the lower seat portion and detachably mounted on the first adaptor to make the child seat disposed on the front leg portion;
wherein when the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

2. The child seat of claim 1 further comprising:
a first locking element movably disposed in the lower seat portion for operably engaging with or disengaging from the first pivot;
a second pivot pivoted to the lower seat portion and the upper seat portion;
a second locking element movably disposed in the upper seat portion for operably engaging with or disengaging from the second pivot;
a linkage element connected to the second locking element and the first locking element; and
a release handle disposed on the upper seat portion and connected to the linkage element;
wherein when the release handle is operated to pull the linkage element, the linkage element drives the second locking element to disengage from the second pivot for making the upper seat portion foldable on the lower seat portion via the second pivot, and the linkage element drives the first locking element to disengage from the first pivot for making the lower seat portion foldable on the front leg portion via the first pivot together with the upper seat portion;
when the release handle is operated to release the linkage element, the first locking element is released to engage with the first pivot for preventing folding of the lower seat portion relative to the front leg portion, and the second locking element is released to engage with the second pivot for preventing folding of the upper seat portion relative to the lower seat portion.

3. The child seat of claim 2 , wherein the linkage element is a cable passing through the second locking element to be connected to the first locking element for pulling or releasing the first locking element and the second locking element simultaneously.

4. The child seat of claim 2 , wherein the second pivot has a concentric track formed therein and an opening communicated with the concentric track, the second locking element has a protrusion protruding toward the opening; when the release handle releases the linkage element, the second locking element is released to move the protrusion to be engaged with a binding surface of the opening for preventing folding of the upper seat relative to the lower seat portion; when the release handle pulls the linkage element to move the protrusion from the opening to the concentric track, the protrusion is movable along the concentric track for making the upper seat portion foldable relative to the lower seat portion.

5. The child seat of claim 2 further comprising:
a tray foldably connected to the upper seat portion via the second pivot;
wherein when the release handle is operated to pull the linkage element, the linkage element drives the second locking element to disengage from the second pivot for making the tray foldable on the upper seat portion via the second pivot;
when the release handle is operated to release the linkage element, the second locking element is released to engage with the second pivot for preventing folding of the tray relative to the upper seat portion.

6. The child seat of claim 2 further comprising:
an armrest foldably connected to the upper seat portion via the second pivot;
wherein when the release handle is operated to pull the linkage element, the linkage element drives the second locking element to disengage from the second pivot for making the armrest foldable on the upper seat portion via the second pivot;
when the release handle is operated to release the linkage element, the second locking element is released to engage with the second pivot for preventing folding of the armrest relative to the upper seat portion.

7. The child seat of claim 1 , wherein the stroller handle has a second adaptor, and the first pivot is detachably mounted on the second adaptor to make the child seat disposed on the stroller handle.

8. The child seat of claim 1 , wherein the upper seat portion has a support member disposed thereon; when the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion, the support member stands on a holding surface for supporting the foldable stroller on the holding surface together with the front leg portion and the stroller handle folded relative to the rear leg portion.

9. A foldable stroller comprising:
a rear leg portion;
a stroller handle foldably connected to the rear leg portion;
a front leg portion foldably connected to the rear leg portion, the front leg portion having a first adaptor; and
a child seat comprising:
a seat frame having an upper seat portion and a lower seat portion, the upper seat portion being foldably connected to the lower seat portion; and
a first pivot foldably connected to the lower seat portion and detachably mounted on the first adaptor to make the child seat disposed on the front leg portion;

wherein when the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

10. The foldable stroller of claim 9 , wherein the child seat further comprises:
a first locking element movably disposed in the lower seat portion for operably engaging with or disengaging from the first pivot;
a second pivot pivoted to the lower seat portion and the upper seat portion;
a second locking element movably disposed in the upper seat portion for operably engaging with or disengaging from the second pivot;
a linkage element connected to the second locking element and the first locking element; and
a release handle disposed on the upper seat portion and connected to the linkage element;
wherein when the release handle is operated to pull the linkage element, the linkage element drives the second locking element to disengage from the second pivot for making the upper seat portion foldable on the lower seat portion via the second pivot, and the linkage element drives the first locking element to disengage from the first pivot for making the lower seat portion foldable on the front leg portion via the first pivot together with the upper seat portion;
when the release handle is operated to release the linkage element, the first locking element is released to engage with the first pivot for preventing folding of the lower seat portion relative to the front leg portion, and the second locking element is released to engage with the second pivot for preventing folding of the upper seat portion relative to the lower seat portion.

11. The foldable stroller of claim 10 , wherein the linkage element is a cable passing through the second locking element to be connected to the first locking element for pulling or releasing the first locking element and the second locking element simultan
