FOLDING STRUCTURAL SYSTEM Russian patent published in 2008 - IPC B62B7/08 

FIELD: articles of domestic utility.

SUBSTANCE: invention refers to a folding structure, which includes a folding perambulator, but is not limited by it. The folding structure contains gliding unit (3) sliding on post (1) along axis (X-X'), at that sliding unit (3) is locked against rotation around the said axis; at least one foldable leg (5) unfolded from a folded position near post (1) into an unfolded position at a distance from post (1). To unfold the leg the folding structure contains coupled structure (7) including, if seen in the direction (Y-Y') different from axis (X-X'), coupled unfolding triangle (21) which in its turn contains first side (22) attached to post (1) between first connection (23) located on post (1) and second connection (25) located at the point of the gliding unit (3), second side (26) attached to gliding unit (3) with second connection (25). Also coupled triangle (21) comprises third side (28) attached to post (1) by means of first connection (23) and to second side (26) by means of third connection (31). At that first connection (23) or second connection (25) contains two distanced points (35) of the connection in the direction (Y-Y'), so that side (28, 26) of unfolding triangle (21) which attached at these points (35) creates rigid guiding triangle (29), determined by these two points (35) and by third connection (31).

EFFECT: designed an easy folded structure which possesses rigidity at unfolded position due to inexpensive and easy in operation means.
