Abstract
Supporting apparatus for a portable bridge including a longitudinally telescoping bridge support leg having an intermediate support member at the free end thereof. A pair of foot plate members are pivotally supported at the intermediate support member and are connected by way of a lever linkage so as to pivot together when moving from a storage position with the undersides of plate members extending longitudinally of the leg and in-use positions with the undersides of the plate members extending transversely of the leg. Elastic band members are attached to the upper sides of the foot plate members to continuously apply a force tending to move the plate members to the in-use position. Rollers are provided at the upper sides of the plate members for engagement with bridge members to forcibly move the plate members to the storage position when the support leg is moved into a storage position underneath the bridge plate portion.
