Abstract (en)
A device to prevent a walking aid from falling over comprising, attached to the walking aid, a pair of foldable standing legs (1) which are joined to the walking aid at their upper ends by means of an upper hinging joint (11, 18) displaceable along the walking aid between a lower and an upper position and are also individually connected with the walking aid by a rod (14,15) which is hingedly fitted between a fixed lower hinging joint (21,22) on the walking aid and a fixed hinging joint (19,20) on the standing leg. The device according to the invention is characterized in that the two standing legs (1) in extended condition, in which the upper hinging joint (11, 18) is in the lower position, constitute together with the walking aid, on a supporting plane, three points of support which form an isosceles triangle in such a way that the projection of the upper hinging joint upon the supporting place is within the said triangle, and that spring means are provided which assist the movement of the upper hinging joint from its upper position to its lower position and its being maintained in that position. The device according to the invention is attachable to any walking aid by simple means. The standing legs can be constructed in a very light material, e.g. plastics, so that they hardly add to the total weight of the walking aid.
