  • Patent number: 10093334
    Abstract: A method and apparatus for joining at least one daughter cart to a mother cart utilize a coupling system having first and second coupling rails attached to one of the mother and daughter cart frames, and a third coupling rail attached to the other of the mother and daughter cart frames. The coupling rails all extend in a parallel manner to one another in a direction generally perpendicular to a primary transport direction and parallel the underlying surface, when engaged for conveying the daughter cart with the mother cart. The third coupling rail is retained in a channel between the first and second coupling rails, in such a manner that the daughter cart is coupled to and moves with the mother cart as the mother cart is moved in the primary transport direction while the third coupling rail is positioned in the channel between the first and second coupling rails.

  • Publication number: 20150101873
    Abstract: A multi-unit mobile robot comprising a plurality of separate carriages or units linked together by linkages. Each unit comprises hinged first and second segments which facilitates pitch relative motion between the segments, and accordingly the units. By controlling actuators to the hinges, one can cause the robot to coil around and compress against the exterior, or compress against the interior, of an object to be traversed. The linkage between mobile units facilitates at least one of lateral pivot or yaw relative motion between units, and optionally roll. Each hinged platform is carried by a pair of Mecanum wheels, which facilitate movement of the unit in any direction. Preferably, alternating units are of differing widths, and the wheels on the units are sufficiently large that they capable of overlapping, thereby enabling the robot to navigate very sharp edges or corners in the surface of an object being traversed by the robot, with the wheels always maintaining contact with the surface being traversed.

  • Publication number: 20080258430
    Abstract: A hitch connection for connecting a lead or “A” trailer to a “B” trailer is disclosed. The hitch connection comprises a female sub-assembly which fits inside the chassis of the “A” trailer at the rear of that trailer. A male sub-assembly which includes a turnplate supported on a chassis includes a tapered prong which locates in the female assembly and is held inside with locking pins. The prong includes a transverse pivot which extends parallel to the axle to allow the prong to pivot relative to the chassis The “B” trailer may be readily separated from the “A” trailer by removal of the locking pins to allow removal of the prong from the female sub-assembly thus allowing unfettered access to the rear of the “A” trailer.

  • Patent number: 7374197
    Abstract: A cart for transporting objects is provided. The cart includes a base structure supported on a plurality of wheels. An elongated tongue is telescopically mounted to an underside of the base structure and is movable between an extended position, wherein the tongue extends in front of the cart, and a retracted position, wherein the tongue is disposed under the cart. A hitch apparatus is mounted to the base structure at the posterior end thereof. The hitch apparatus includes a hitch for receiving a tongue of another cart and a locking assembly for locking the tongue to the hitch. The locking assembly includes a pin movable between locking and release positions. A tongue actuator is connected to the tongue and is operable, upon manipulation by an operator, to move the tongue from the retracted position to the extended position, while a hitch actuator is connected to the pin of the locking assembly and is operable, upon manipulation by an operator, to move the pin from the locking position to the release position.

  • Patent number: 6550794
    Abstract: The present invention comprises sets of teeth that are spaced apart from each other in a sawtooth configuration and project horizontally outward from the front and rear ends of a hand propelled, wheeled cart. The front teeth of one cart are capable of intermeshing with the opposed rear teeth of another cart. The intermeshing teeth restrict the carts from independent lateral motion, so that when two or more carts are pushed from the rear, all carts stay in alignment with each other. This allows two or more carts to be pushed as one unit, either in a straight line or around turns.
