Wheeled Chair, Stroller, Or Baby Carriage Patents (Class 280/647)
  • Patent number: 10435057
    Abstract: A collapsible chassis for strollers includes a base frame supporting at least one front post and at least one rear post with wheel assemblies. The base frame further supports at least one handle tube. An actuation element is supported by the base frame and is actuated by the user to move the chassis from the open condition to the closed condition. The actuation element is movable with respect to both the handle tube and the movable post and is connected by way of a first kinematic connection element to the movable post and by way of a second kinematic connection element to the handle tube. Actuating the actuation element causes the rotation of the movable post and handle tube. A third kinematic connection element is provided which includes an articulation element adapted to cause a motion of mutual approach in a transverse direction of the two rear posts.

  • Patent number: 10279831
    Abstract: A collapsible child's stroller with a handle frame (30), a front wheel frame (10) and a rear wheel frame (20), mutually connected at a hinge joint (12, 22, 42) for mutual angular displacement between folded and unfolded configurations. The hinge joint has two spaced apart, parallel hinge axes, about which the frames (10, 20, 30) mutually rotate. The stroller is further provided with a locking element (43, 44) moveable between a locked position in which the frames (10, 20, 30) are locked in the unfolded configuration, and an unlocked position allowing the frames (10, 20, 30) to rotate to the folded configuration. The locking element (43, 44) moves in a direction traverse to the parallel hinge axes to better transfer loads between the frames.
