Abstract
A foldable stroller frame comprising a lower frame. The lower frame has a front frame section and a rear frame section which are pivotal relative to one another. The lower frame also has a hinge device linking the front frame section to the rear frame section. The hinge device has at least two parts pivotally coupled together and rotatable about a movable axis of rotation between a deployed state and a collapsed state. The hinge device also has a handle arranged along the axis of rotation for grasping by a user to enable the hinge device to be operated.
Claims23
A foldable stroller frame comprising a lower frame, the lower frame comprising:
- a front frame section having an end portion with at least one or more ground engaging wheels connected thereto,
- a rear frame section having an end portion with at least two ground engaging wheels connected thereto, the front frame section being pivotally connected to the rear frame section, and
- a hinge device extending from the end portion of the front frame section to the end portion of the rear frame section,
- wherein the hinge device comprises at least two coupled parts rotatable about a movable axis of rotation, said coupled parts configured to position the axis of rotation forward of the pivotal connection between the front and rear section, and
- a handle arranged along the movable axis of rotation for grasping by a user to operate the hinge device for pivotal movement of the front frame section relative to the rear frame section between a deployed state and a collapsed state.
A method of folding a foldable stroller frame having a lower frame comprising two pivotally connected frame sections linked by a hinge device, the hinge device having a handle arranged along an axis of rotation of the hinge device, wherein said axis of rotation is disposed forwardly with respect to the pivotal connection of the frame sections when the stroller is in a deployed state, the method comprising the steps of:
- reaching through an aperture formed in a base of a basket mounted on the stroller frame to grasp the handle;
- and
- pulling the handle in an upward direction to cause the hinge device to draw the pivotally connected frame sections together into a collapsed state.
A foldable stroller frame comprising a lower frame, the lower frame comprising a front frame section, a rear frame section and a hinge device linking the front frame section to the rear frame section, the front frame section being pivotally connected to the rear frame section, wherein the hinge device comprises at least two coupled parts rotatable about a movable axis of rotation and a handle arranged along the movable axis of rotation for grasping by a user to operate the hinge device for pivotal movement of the front frame section relative to the rear frame section between a deployed state and a collapsed state;
- wherein the lower frame further comprises a latch mechanism operable to latch the front frame section to the rear frame section in the collapsed state;
- and
- wherein two coupled parts of the at least two coupled parts of the hinge device comprise interfacing formations which together define a space, each formation having one or more shaped features for engagement with one or more correspondingly shaped features of a locking member mounted within the space, wherein the locking member is moveable between an unlocked position in which the two coupled parts are relatively moveable and a locked position in which the two coupled parts are fixed relative to each other, the locking member engaging only one formation in the unlocked position and engaging both formations in the locked position.
