CN2573341Y - Transversely and longitudinally folding perambulator - Google Patents

Abstract

The utility model relates to a transversely and longitudinally folding perambulator. The upper end part of a second back connecting rod [3] is pivoted on a first sliding sleeve [4]; the first sliding sleeve [4] can be glidingly sheathed on a first back leg [5]; the upper end part of a first back connecting rod is pivoted with a second sliding sleeve [9]; the second sliding sleeve [9] can be glidingly sheathed on a second back leg [6]. When the perambulator is folded, two sliding sleeves can respectively slide along two corresponding back legs. When the perambulator is in an opening state, the positions of the sliding sleeves can be greatly decreased, without influencing the arrangement of a seat frame; the seat frame can be protruded towards the back of the back legs; therefore, a back cross support of the utility model is shrunk; the manufacturing cost is reduced.
