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 support 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.

Claim (Index 13):
A collapsible chassis comprising a base frame that supports at least one front post and at least one rear post, connected in a lower region to respective wheel assemblies, at least one disposed between said at least one front post and said at least one rear post being movable with a rotary motion with respect to said base frame about an articulation axis that is substantially transverse to the direction of longitudinal extension of said chassis during transition of said chassis from an extended open condition to a collapsed closed condition and during transition of said chassis from the collapsed closed condition to the extended open condition, said base frame supporting further at least one handle tube, which defines grip means and moves with a rotary motion with respect to said lower frame about a pivoting axis that is substantially transverse to the direction of longitudinal extension of said chassis during transition of said chassis from the extended open condition to the collapsed closed condition and transition of said chassis from the collapsed closed condition to the extended open condition, and further comprising an actuation element that is supported by said base frame and is actuated by the user to move said chassis from said open condition to said closed condition, said actuation element being movable with respect to said handle tube and with respect to said at least one of said front and rear post that is movable being connected by way of first kinematic connection means to said at least one post that is movable with respect to said base frame about said articulation axis and, by way of second kinematic connection means, to said handle tube, the actuation of said actuation element causing the rotation, with respect to said base frame, of said at least one movable post about said articulation axis and of said handle tube about said pivoting axis, said chassis comprising two rear posts that move, with respect to said base frame, about a respective folding axis that is substantially parallel to the central plane of said chassis and substantially perpendicular to the longitudinal direction of the respective rear post, third kinematic connection means being provided for connection between said actuation element and said two rear posts, said third kinematic connection means comprising articulation means adapted to cause, during transition of said chassis from said extended open condition to said collapsed closed condition, a motion of mutual approach in a transverse direction of said two rear posts by means of a rotation about the respective folding axis.
