Abstract

A collapsible stroller includes a stroller frame moveable between a deployed position and a collapsed position and a latch mechanism. The stroller frame includes a first leg, a second leg and a handle support member. The handle support member is pivotable with respect to the first leg or the second leg. The latch mechanism includes a latch body and a catch. The latch body is positioned internally of the second leg. When the stroller is in the deployed position, the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view. The catch is provided on or connected with the first leg or the handle support member. The latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller is in the collapsed position.

First claim

The invention claimed is:

1. A collapsible stroller comprising:
a stroller frame movable between a deployed position and a collapsed position, the stroller frame comprising
a first leg;
a second leg connected with and movable with respect to the first leg between a first position and a second position; and
a handle support member connected with the first leg or the second leg and pivotable with respect to the first leg or the second leg; and

a latch mechanism on the stroller frame, the latch mechanism comprising
a latch body positioned internally of the second leg such that when the stroller frame is in the deployed position the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view, wherein the second leg is pivotable with respect to the latch body, wherein the second leg pivots with respect to the latch body about a leg collapse axis and the handle support member pivots with respect to the first leg about a handle collapse axis, which is parallel with and offset from the leg collapse axis, between an upright position and a folded position; and
a catch provided on or connected with the first leg or the handle support member so as to be movable with the first leg or the handle support member, wherein the latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller frame is in the collapsed position to maintain the stroller frame in the collapsed position.

2. The stroller of claim 1 , wherein the second leg pivots with respect to the latch body about the leg collapse axis when the stroller frame is moving between the deployed position and the collapsed position, and the catch connects with the latch body when the handle support member is in the folded position.

3. A collapsible stroller comprising:
a stroller frame movable between a deployed position and a collapsed position, the stroller frame comprising
a front leg;
a rear leg connected with and movable with respect to the front leg between a first position and a second position; and
a handle support member connected with the front leg or the rear leg and pivotable with respect to the front leg or the rear leg;

a hinge mechanism connecting the rear leg with the front leg such that the rear leg pivots with respect to the front leg;
an axle connecting the handle support member with the front leg; and

a latch mechanism on the stroller frame, the latch mechanism comprising
a latch body positioned internally of the rear leg such that when the stroller frame is in the deployed position the latch body is blocked from view by the rear leg when the stroller frame is viewed in a side elevation view;
a catch provided on or connected with the front leg or the handle support member so as to be movable with the front leg or the handle support member, wherein the latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller frame is in the collapsed position to maintain the stroller frame in the collapsed position,

wherein the front leg pivots with respect to the rear leg about a leg collapse axis intersecting the hinge mechanism, and the handle support member pivots with respect to the front leg about a handle collapse axis, which is parallel with and offset from the leg collapse axis, extending through the axle.

4. The stroller of claim 3 , wherein the latch body is positioned internally of the rear leg such that when the stroller frame is in the deployed position the latch body is blocked from view by the rear leg when the stroller frame is viewed in the side elevation view.

5. The stroller of claim 4 , wherein the stroller frame further includes a seat frame assembly, wherein the rear leg has an internal side, which faces internally toward the seat frame assembly, and an external side, which faces away from the seat frame assembly, and the latch body mounts adjacent to the internal side of the rear leg.

6. The stroller of claim 5 , wherein the latch body mounts to a hinge mechanism housing, which is part of the hinge mechanism.

7. The stroller of claim 3 , wherein the rear leg pivots with respect to the front leg about a leg collapse axis and the latch body does not rotate with respect to the front leg about an axis parallel with leg collapse axis.

8. A collapsible stroller comprising:
a stroller frame movable between a deployed position and a collapsed position, the stroller frame comprising
a first leg;
a second leg connected with and movable with respect to the first leg between a first position and a second position; and
a handle support member connected with the first leg or the second leg and pivotable with respect to the first leg or the second leg; and

a latch mechanism on the stroller frame, the latch mechanism comprising
a latch body positioned internally of the second leg such that when the stroller frame is in the deployed position the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view; and
a catch provided on or connected with the first leg or the handle support member so as to be movable with the first leg or the handle support member, wherein the latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller frame is in the collapsed position to maintain the stroller frame in the collapsed position,

wherein the second leg pivots with respect to the latch body about a leg collapse axis and the latch body pivots with respect to the second leg about a latch body pivot axis, wherein the leg collapse axis is perpendicular to the latch body pivot axis.

9. The stroller of claim 8 , wherein the latch body is biased in direction perpendicular to the latch body pivot axis.

10. The stroller of claim 9 , wherein the latch body includes a button section adjacent a first end of the latch body and a catch engaging portion positioned nearer to a second end of the latch body, wherein the first end is opposite the second end, and the catch engaging portion contacts the catch when the stroller frame is in the collapsed position.

11. The stroller of claim 10 , wherein the button section is biased in a first direction perpendicular to the latch body pivot axis, which urges the catch engaging portion in a second direction, which is opposite to the first direction.

12. The stroller of claim 11 , wherein the catch is a bump and the catch engaging portion includes a ledge, wherein the second end of the latch body moves in the first direction when riding over the bump when the stroller frame is moving from the deployed position toward the collapsed position.

13. The stroller of claim 11 , wherein the button section is configured to be depressed in the second direction when the catch engaging portion is engaged with the catch with the stroller frame in the collapsed position to disconnect the latch body with the catch.

14. A collapsible stroller comprising:
a stroller frame movable between a deployed position and a collapsed position, the stroller frame comprising
a first leg;
a second leg connected with and movable with respect to the first leg between a first position and a second position; and
a handle support member connected with the first leg or the second leg and pivotable with respect to the first leg or the second leg; and

a latch mechanism on the stroller frame, the latch mechanism comprising
a latch body positioned internally of the second leg such that when the stroller frame is in the deployed position the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view,
