  • Patent number: 4989889
    Abstract: Foldable cart for shopping having a rigid base for reinforcement of the bag bottom. Two frames carry the wheels on which the bag leans in the unfolded position during use. The frames allow the wheels to be folded beneath the rigid base. Bag supporting frameworks can be extended and folded by parallel sliding in order to allow extension for pulling the cart or folding to a bag of reduced size for hand transport. One of the frameworks is attached to the upper zone of the bag, pulling the latter for its extension or folding. The other framework has, close to an articulation axle at the rigid base of the bag, a piece provided with one or two lugs which pass through slots formed in the housing for articulation of the frameworks and the wheel frames and for automatic extension of the wheels.

  • Patent number: 4869177
    Abstract: The semi-trailer is capable of traveling on roads or on rails. It is characterized in that both a rail truck and a highway carriage are rapidly removable. Therefore the semi-trailer can travel on roads with only the highway carriage, and on rails with only the rail truck. The advantage is a reduction in the tare of the rail-operable unit. An additional advantage is the lack of a need for all the means intended for maintaining the wheels of the highway carriage elevated above the plane of the rails when traveling on rails, which means are required for all prior art binary rail and road vehicles. Other characteristics of the invention are the coupling device between the semi-trailers, the system of connection of a center pin socket to a hemispherical center-bearing counter-element of the rail truck, and the use of special support props and jacks.
