A folding chassis (1) for push-chairs, baby carriages and the like, comprising—a lower frame (2), which has at least one front post (2a) and at least one rear post (2b), which are connected in a lower region to respective wheel assemblies (3a, 3b);—at least one upper post (4), which supports grip me
A folding chassis (1) for push-chairs, baby carriages and the like, comprising—a lower frame (2), which has at least one front post (2a) and at least one rear post (2b), which are connected in a lower region to respective wheel assemblies (3a, 3b);—at least one upper post (4), which supports grip means (4a) and can move with a combined rotary and translational motion with respect to the lower frame (2) during the transition of the chassis from an extended open condition to a collapsed closed condition;—at least one interconnection linkage (5), which is articulated rotatably to the upper post (4) and to the rear post (2b) about a first articulation axis (101) and a second articulation axis (102);—means (7) for kinematic interconnection between the upper post (4) and the lower frame (2);—the interconnection linkage (5) and the kinematic interconnection means (7) being adapted to determine the relative motion between the front post or posts, the rear post or posts and the upper post or posts (4) during the transition of the chassis (1) from the extended open condition to the collapsed closed condition and vice versa,—locking means (10) which can be activated, as a consequence of the transition of the chassis (1) from the collapsed closed condition to the extended open condition, and are adapted to keep the chassis (1) in the extended open condition,—a deactivation device (20), which is adapted to deactivate on command the locking means (10) in order to allow the transition of the chassis (1) from the extended open condition to the collapsed closed condition, at least one grip device (30) and at least one actuation device (31) being associated with the lower frame (2), said actuation device (31) being able to be actuated, with the locking means (10) deactivated and the grip device (30) gripped by the user, so as to move, by means of a movement of a linkage (5) and/or of an upper post (4), the first articulation axis (101) away from the rear post or posts (2b), so as to move beyond a position of equilibrium of the chassis (1) beyond which the chassis (1) tends to move towards the collapsed closed condition due to its own weight.

1. A folding chassis for push-chairs and baby carriages, comprising: a lower frame, which has at least one front post and at least one rear post, which are connected in a lower region to respective wheel assemblies;at least two upper posts, each of which supports grip means and can move with a combined rotary motion and a translational motion with respect to said lower frame during the transition of said chassis from an extended open condition to a collapsed closed condition;at least one interconnection linkage, which is articulated rotatably to said at least two upper posts and to said at least one rear post about a first articulation axis and a second articulation axis;means for kinematic interconnection between said at least two upper posts and said lower frame;said interconnection linkage and said kinematic interconnection means provide for relative motion between said at least one front post, said at least one rear post and said at least two upper posts during the transition of said chassis from the extended open condition to the collapsed closed condition and vice versa,locking means which can be activated, as a consequence of the transition of said chassis from the collapsed closed condition to the extended open condition, and can keep said chassis in the extended open condition,a deactivation device, which deactivates said locking means in order to allow the transition of said chassis from said extended open condition to said collapsed closed condition,wherein at least one grip device and at least one actuation device are connected to said lower frame, said actuation device is actuated when said locking means is deactivated and said grip device is rotated by a user, wherein said first articulation axis is moved away from said at least one rear post, by means of a movement of said at least one interconnection linkage or of said at least two upper posts, such that said chassis moves beyond a position of equilibrium and moves towards the collapsed closed condition,wherein said at least one front post is articulated rotatably to said at least one rear post about at least one interconnection axis, and wherein said kinematic interconnection means comprising:at least two upper traction elements pivoted to said rear post at a front region, said at least two upper traction elements being arranged proximate to said interconnection axis, each of said at least two upper traction elements being coupled rotatably to said at least one upper post about a third articulation axis, wherein the third articulation axis is parallel to said interconnection axis, andat least one lower traction element pivoted to said at least one front post and is coupled rotatably to said at least one interconnection linkage about a fourth articulation axis, wherein the fourth articulation axis is parallel to said interconnection axis. 2. The folding chassis according to claim 1, wherein said grip device comprises a handle that is movable, along a movement path, with respect to said lower frame. 3. The folding chassis according to claim 1, wherein said grip device comprises a handle which is articulated to said lower frame. 4. The folding chassis according to claim 3, wherein said handle can move, with respect to said lower frame, so as to shift between an inactive condition and a lifting condition. 5. The folding chassis according to claim 3, wherein said actuation device is connected kinematically to said handle. 6. The folding chassis according to claim 4, wherein said actuation device can be actuated following the transition of said handle from said inactive condition to said lifting condition. 7. The folding chassis according to claim 3, wherein said actuation device comprises a lever system which is connected to said handle and is adapted to operate by pushing against said interconnection linkage. 8. The folding chassis according to claim 3, wherein said deactivation device is connected to said handle. 9. The folding chassis according to claim 4, wherein said deactivation device has a first deactivation element and a second deactivation element, which can be actuated independently of each other. 10. The folding chassis according to claim 9, wherein said first deactivation element is connected kinematically to said handle, said handle being movable between said inactive condition and a condition of actuation of said first deactivation element, said actuation condition being interposed between said inactive condition and said lifting condition. 11. The folding chassis according to claim 9, wherein said second deactivation element comprises a release button which is connected to said locking means. 12. The folding chassis according to claim 11, wherein said release button is arranged proximate to said handle. 13. The folding chassis according to claim 3, wherein said handle is articulated rotatably to said lower frame about an articulation axis which is substantially parallel to said interconnection axis. 14. The folding chassis according to claim 7, wherein said lever system comprises at least one strut which terminates in a working end which is adapted to operate by pushing against said interconnection linkage in order to move said pivoting axis beyond said equilibrium condition. 15. The folding chassis according to claim 14, wherein said at least one strut is guided along a guiding receptacle which is articulated to said lower frame. 16. The folding chassis according to claim 14, wherein said handle, during the transition between said inactive condition and said actuation condition, is adapted to move said at least one strut along said guiding receptacle in order to cause, by means of a movement of a contoured portion thereof, the rotation, about a pivoting axis, of a locking hook which forms said locking means. 17. The folding chassis according to claim 9, wherein the further movement of said handle from said actuation condition to said lifting condition in order to cause the actuation of said actuation device is allowed once said second deactivation element has been actuated.
