  • Patent number: 6293398
    Abstract: An elongate member with a first hook at one end and a relatively sliding hook received on the elongate member are disposed in opposing relation for securing a durable good such as a riding lawn mower to a pallet. The sliding hook attaches to a sleeve in order to move relative to the first hook. A nut engages a threaded portion of an opposing end of the elongate member to bear against the sliding hook to secure it in position. The first hook engages a portion of the pallet, and the sliding hook engage a portion of the durable good received on the pallet. The nut restrains the sliding hook from moving away from the first hook, and thereby securing the durable good to the pallet. A wood-cleated corrugated paperboard body is received on the pallet to enclose the durable good. A method of securing a durable good such as a riding lawn mower to a pallet is disclosed.

  • Patent number: 6003704
    Abstract: A cleated crate having opposing side panels and opposing end panels, hingedly connected together pairs of opposing inner and outer hinges which define corners in the crate. Each hinge comprises a pair of members having trapezoidal shapes in cross-section which defines a neck surface and an opposing shoulder surface and an oblique surface and an opposing back surface. The elongated members in the inner hinges are disposed in mirrored relation with the necks side-by-side and the oblique surfaces defining a V-shaped channel on a side of the hinge. The members are secured together by a pair of U-shaped staples driven into the butt ends. The members pivot to a second position for bringing the oblique surfaces into bearing contact. The elongated members in the outer hinges are disposed in mirrored relation with the distal edges of the members defined by the respective oblique surface and the shoulder surface in touching contact. The oblique surfaces define a V-shaped channel on a side of the hinge.

  • Patent number: 5813555
    Abstract: The present invention provides a cleated crate for packaging, storing, and shipping heavy articles. The cleated crate includes a base frame for supporting an article to be packed, a pair of wing-end frames that define ends and side portions of the cleated crate. The wing-end frames comprise a pair of hinge corners each having a pair of spaced apart cleats attached to a fibreboard plate with a score along an axis. The fibreboard plate folds on the score to define a corner post of the cleated crate. A portion of the side of the cleated crate is defined by a side member and a support member attached to one of the pairs of cleats on the fibreboard plate. Elongate members connect two hinge corners together to define a wing-end frame. A pair of wing-end frames are positioned and attached to opposite ends of a base frame or pallet. Intermediate connectors rigidly connect on opposite sides to aligned hinge corners at the opposite ends of the cleated container.
