Problems solved by technology

[0010] This type of folding allows for less bulk in the collapsed position, but is not compatible with certain equipment used on collapsible racks, such as rigid infant seats, or enclosures, or non-collapsible hammocks
This therefore requires the use of such folds to be limited to foldable hammocks (which are generally less comfortable than rigid hammocks) or to remove the child transport equipment (baby seat, enclosure, hammock, etc.) before each fold

Embodiment Construction

[0065] Principle of invention

[0066] As explained above, the present invention relates to an improvement of a trolley that can be folded three-dimensionally, offering the possibility to choose between two types of folding, for example a simple and fast 2-dimensional folding suitable when using non-foldable hammocks ( 2D folding - the lateral components are kept apart from each other but are folded) and compact folding in three dimensions (3D folding - the lateral components are folded and brought together) requiring a suitable collapsible hammock or hammock prior removal.

[0067] Depending on the situation, 3D folding can be obtained directly after 2D folding or without going through 2D folding. In order to allow this choice between 2D and 3D folding, the dynamic connection between the lateral assemblies of the frame of the trolley and the cross-struts linking these assemblies can be disengaged in order to in some cases connect the folding of the lateral assemblies and th...

Abstract

The present invention relates to a foldable chassis for a pushchair, which comprises two foldable side components (1a), each side components comprises front support rods (2a, 2b) and rear support rods (3a, 3b); and a device for controlling the distance between the side components (1a, 1b) so as to make them be brought together in a compact folding position and be separated each other in a unfolding position, the foldable chassis is characterized in that: the chassis has a device for selectively combining the distance controlling device and the side components (1a) so as to two type foldings of the chassis adopting active and inactive states: compact folding, wherein the side components (1a, 1b) are folded at the same time under the active state, each rear support rods (3a, 3b) are broght into and are basically parallel to the corresponding front support rods (2a, 2b), and the side components (1a, 1b) are brought by the distance controlling device; and flat folding, wherein each components (1a, 1b) are folded under the inactive state, the rear support rods (3a, 3b) are broght into and are basically parallel to the corresponding front support rods (2a, 2b), two side components (1a, 1b) keep partition each other, and the distance controlling device is separated from the side components (1a, 1b).

Description

technical field [0001] The field of the invention is children's strollers. More specifically, the present invention relates to the improvement of the folding and unfolding of the trolley, and in particular the adaptation of this folding to the needs of the user and the conditions encountered by the user. Background technique [0002] Trolley structure [0003] Numerous cart types are known and are broadly classified according to their folding mode. Many of these carts are substantially symmetrical, and their frames have two lateral assemblies, each typically comprising a front wheel bracket (or front strut) that supports the front wheels, a rear wheel bracket that supports the rear wheels, and a rear wheel bracket that supports the rear wheels. (or rear struts), and push elements (or push arms). These lateral elements are respectively positioned in two planes substantially parallel to each other and to the plane of symmetry of the trolley and are interconnected by other ...
