<p>A book-like foldable frame (10) in particular for baby strollers, comprising a pair of front legs (11), respectively a right front leg and a left front leg which are laterally spaced from each other and which are associated with each other so as to form a single body, a pair of rear legs (13), respectively a right rear leg and a left rear leg which are laterally spaced from each other and which are associated with each other so as to form a single body, a pair of handle rods (15), respectively a right handle rod e a left handle rod which are laterally spaced from each other and which are associated with each other so as to form a single body, a pair of articulation groups (17), respectively a right articulation group which articulates the right front leg (11), the right rear leg (13) and the right handle rod (15) with each other and a left articulation group which articulates the left front leg (11), the left rear leg (13) and the left handle rod (15) with each other for the book-like closure of the frame (10), wherein the pair of handle rods (15) and the pair of front legs (11) rotate each as a single body respectively about a first axis (A) and a second axis (B) relative to the pair of rear legs (13) or wherein the pair of handle rods (15) and the pair of rear legs (13) rotate each as a single body respectively about a first axis (A) and a second axis (B) relative to the pair of front legs (11) and wherein the first and second axes (A, B) are parallel to each other and to the supporting ground of the frame (10) and orthogonal to the advancement direction of the frame (10), and that is characterised in that it comprises an attaching base (30) of a baby seat unit which is associated through a cylindrical rotary coupling (31) with the pair of front legs (11) or with the pair of rear legs (13) so as to be able to rotate about a third rotation axis (C) parallel to the first and second axes (A, B), blocking means (35) of the rotation of the attaching base (30) about the third rotation axis (C) which are movable between a blocking position and a de-blocking position of the rotation of the attaching base (30), a control handle (36) which is hinged to the attaching base (30) so as to be able to rotate about a hinging axis (D) parallel to the third rotation axis (C), and a stop element (37) of the rotation of the control handle (36) with respect to the attaching base (30) which is associated with the control handle (36) in a movable manner between a stop position and a release position of the rotation of the control handle (36) with respect to the attaching base (30), wherein the movement of the blocking means (35) from the blocking position to the de-blocking position of the rotation of the attaching base (30) is controlled by the rotation of the control handle (36) about the respective hinging axis (D) or by the movement of the stop element (37) between the stop position and the release position of the rotation of the control handle (36).</p> |
