The present invention relates to a buggy or collapsible perambulator. It is comprised of a sliding frame which, in the unfolded state, runs in an inclined plane and has a division, in the region of which joints are located, and therefore, upon collapsing, an upper portion of the sliding frame is pivotable in relation to a lower portion of the sliding frame about the approximately horizontal axis of said joints. It is further comprised of an underframe with wheels, wherein, in the collapsed state, the lower portion and upper portion of the sliding frame and at least parts of the underframe are virtually parallel or are at a flat angle to each other and the buggy assumes a flat, compact state. The two sliding-frame portions which are pivotable in relation to each other each have approximately the shape of a U bar.

1. A buggy or collapsible perambulator, comprising a sliding frame which, in the unfolded state, runs in an inclined plane and has a division, in the region of which joints are located, and therefore, upon collapsing, an upper portion of the sliding frame is pivotable in relation to a lower portion of the sliding frame about the approximately horizontal axis of said joints, and furthermore comprising an underframe with wheels, wherein, in the collapsed state, the lower portion and upper portion of the sliding frame and at least parts of the underframe are virtually parallel and the buggy assumes a flat, compact state, wherein the two portions of the sliding frame, which are pivotable in relation to each other, each have approximately the shape of a U bar, wherein suspensions of the front wheels are located on the lower portion of the sliding frame, and suspensions for rear wheels are located on a rear frame of the underframe, said rear frame having a horizontal first transverse strut, wherein an articulated sleeve, which runs in transverse direction, is located on the lower portion of the sliding frame, and said horizontal first transverse strut of the rear frame is accommodated in this articulated sleeve so as to be pivotable about a horizontal axis, andwherein support struts are provided on both sides of the underframe, the lower end of each support strut is attached to the rear frame of the underframe in an articulated manner and the upper end of each support strut is attached to the upper portion of the sliding frame in an articulated manner. 2. The buggy according to claim 1, wherein the rear frame of the underframe encompasses a support leg on each side, to which an axle for a rear wheel is in each case integrally molded in the lower end region. 3. The buggy according to claim 1, wherein the lower portion of the sliding frame is a component, which is injection molded of plastic in one piece, in the form of a U strut, which is open towards the top of the buggy, comprising joint halves of the joints for the articulated connection to the upper portion of the sliding frame, in each case in the upper end region of two journals of the U-strut. 4. The buggy according to claim 3, wherein sleeves, in which the suspensions of the front wheels are located so as to be rotatable about a vertical axis and thus so as to be steerable, are furthermore injection molded in the lower end region on the lower portion of the sliding frame. 5. The buggy according to claim 3, wherein the upper portion of the sliding frame is a component, which is injection molded of plastic in one piece, in the form of a U strut, which is open towards the bottom, in each case comprising corresponding joint halves of the joints for the articulated connection to the lower portion of the sliding frame. 6. The buggy according to claim 5, wherein elements for a fastening of a textile seat are furthermore injection molded to journals of the U strut of the upper portion of the sliding frame. 7. The buggy according to claim 1, wherein the horizontal first transverse strut of the rear frame encompasses spanner flats, to which correspondingly dimensioned assembly accommodations are assigned in the articulated sleeve on the lower portion of the sliding frame, so that, after the assembly of the buggy, the horizontal first transverse strut can no longer be removed from the articulated sleeve, which accommodates said horizontal first transverse strut so as to be pivotable about a horizontal axis. 8. A buggy or collapsible perambulator, comprising a sliding frame which, in the unfolded state, runs in an inclined plane and has a division, in the region of which joints are located, and therefore, upon collapsing, an upper portion of the sliding frame is pivotable in relation to a lower portion of the sliding frame about the approximately horizontal axis of said joints, and furthermore comprising an underframe with wheels, wherein, in the collapsed state, the lower portion and upper portion of the sliding frame and at least parts of the underframe are virtually parallel and the buggy assumes a flat, compact state, wherein the two portions of the sliding frame, which are pivotable in relation to each other, each have approximately the shape of a U bar, wherein suspensions of front wheels are located on the lower portion of the sliding frame, and suspensions for rear wheels are located on a rear frame of the underframe, said rear frame having a horizontal first transverse strut, wherein an articulated sleeve, which runs in transverse direction, is located on the lower portion of the sliding frame, and said horizontal first transverse strut of the rear frame is accommodated in this articulated sleeve so as to be pivotable about a horizontal axis, andwherein the rear frame of the underframe is a component, which is injection molded of plastic in one piece, comprising two support legs, the horizontal first transverse strut, which connects the two support legs to each other on the top, in each case an axle for a rear wheel, integrally molded to each support leg in each case in the lower end region, as well as, if necessary, a lower second transverse strut, which connects the two support legs. 9. A buggy or collapsible perambulator, comprising a sliding frame which, in the unfolded state, runs in an inclined plane and has a division, in the region of which joints are located, and therefore, upon collapsing, an upper portion of the sliding frame is pivotable in relation to a lower portion of the sliding frame about the approximately horizontal axis of said joints, and furthermore comprising an underframe with wheels, wherein, in the collapsed state, the lower portion and upper portion of the sliding frame and at least parts of the underframe are virtually parallel and the buggy assumes a flat, compact state, wherein the two portions of the sliding frame, which are pivotable in relation to each other, each have approximately the shape of a U bar, wherein suspensions of front wheels are located on the lower portion of the sliding frame, and suspensions for rear wheels are located on a rear frame of the underframe, said rear frame having a horizontal first transverse strut, wherein an articulated sleeve, which runs in transverse direction, is located on the lower portion of the sliding frame, and said horizontal first transverse strut of the rear frame is accommodated in this articulated sleeve so as to be pivotable about a horizontal axis,wherein sliding frame and underframe, comprising all of the significant functional components, consist of a total of only five injection molded components made of plastic, which can be connected to each other,namely a component, which comprises the upper portion of the sliding frame,a component, which comprises the lower portion of the sliding frame,a component, which comprises the rear frame,as well as two support struts, the lower end of which is in each case attached to the rear frame of the underframe in an articulated manner and the upper end of which is in each case attached to the upper portion of the sliding frame in an articulated manner.
