Abstract
Abstract Systems for anchoring a load or container on a flatbed and particularly adapted to be used with existing containers without alteration thereto and which systems are simple and readily and safely anchor a container on a flatbed. Such load anchoring system comprises a beam secured on the flatbed, a slideway formed in the beam, an anchoring member slidable in the slideway and having a prong engageable endwise into an aperture in the corner post of a container, and a lever pivoted relative to the prong to register with the anchoring member in the path of displacement thereof to block the prong against retraction from the aperture in the corner post.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
284 words
A system for anchoring an elongated container in transport position longitudinally of a flat bed vehicle, said container being of the type having a recess, or aperture, made in the lower end of each corner thereof and opening at the end faces of said container, said system comprising beams secured to said flat bed transversely thereof and spaced apart longitudinally of said flat bed a distance substantially equal to the length of said container for supporting said container off said flat bed at the four corners thereof, means to positively locate the four corners of said container in vertical register with the outer ends of said beams, a slideway carried by said beams at each outer end thereof, each slideway extending through and transversely of the associated beam and being substantially parallel to the flat bed of the vehicle, an anchor member for each slideway, said anchor member having a slide portion slidable along the associated slideway for slidable movement in a direction substantially parallel to said flat bed and towards and away from the corresponding end face of said container between a container-anchoring position and a container-releasing position, respectively, a prong carried by said anchor member and facing said container end face and engaging said recess in said container-anchoring position of said anchor member and clearing said recess in said container-releasing position of said anchor member, and a locking lever associated with each anchor member freely pivotally mounted at one end about an axis extending longitudinally of said flat bed for pivotal movement in a plane transverse to the direction of slidable movement of said anchor member, to take under gravity an operative limit position, locking said anchor member in said container-anchoring position.
Claim 2
Independent Claim
284 words
A system for anchoring an elongated container in transport position longitudinally of a flat bed vehicle, said container being of the type having a recess, or aperture, made in the lower end of each corner thereof and opening at the end faces of said container, said system comprising beams secured to said flat bed transversely thereof and spaced apart longitudinally of said flat bed a distance substantially equal to the length of said container for supporting said container off said flat bed at the four corners thereof, means to positively locate the four corners of said container in vertical register with the outer ends of said beams, a slideway carried by said beams at each outer end thereof, each slideway extending through and transversely of the associated beam and being substantially parallel to the flat bed of the vehicle, an anchor member for each slideway, said anchor member having a slide portion slidable along the associated slideway for slidable movement in a direction substantially parallel to said flat bed and towards and away from the corresponding end face of said container between a container-anchoring position and a container-releasing position, respectively, a prong carried by said anchor member and facing said container end face and engaging said recess in said container-anchoring position of said anchor member and clearing said recess in said container-releasing position of said anchor member, and a locking lever associated with each anchor member freely pivotally mounted at one end about an axis extending longitudinally of said flat bed for pivotal movement in a plane transverse to the direction of slidable movement of said anchor member, to take under gravity an operative limit position, locking said anchor member in said container-anchoring position.
Claim 3
Dependent Claim
22 words
A system as claimed in claim 1, wherein said locking lever is pivotally mounted on a pin, itself secured to said beam.
Claim 4
Dependent Claim
33 words
A system as claimed in claim 1, wherein said locking lever is pivotally connected directly to said prong and extends beyond the same to engage under gravity an inner surface in said recess.
Claim 5
Dependent Claim
98 words
A system as claimed in claim 1, wherein said slideway is formed by a passage extending through the end of the beam and opening at the opposite sides thereof and by a plate secured to said beam and extending vertically in the center of said passage and said slide portion of said anchor member includes a rectangular frame slidable within said passage with said plate extending within said frame, said anchor member rigidly upstanding from an end of said frame and said prong rigidly fixed to the upper end of said anchor member and extending towards said beam.
Claim 6
Dependent Claim
60 words
A system as claimed in claim 1, wherein said slideway consists of a rod member secured to the outer end of said beam transversely of said beam and extending therefrom in a direction away from the end face of said container, and said slide portion of said anchoring member consists of a sleeve surrounding said rod member and slidable thereon.
Claim 7
Dependent Claim
197 words
A system as claimed in claim 5, further including an additional beam secured to said flat bed transversely thereof and located close to one of said first-named beams for receiving the end corners of an additional container located longitudinally of said flat bed with one end face close to, but spaced from, the adjacent end face of the first-named container, said additional beam having means to positively locate the corners of the adjacent additional container in vertical register with the outer ends of said additional beam, said rod member extending across the two closely adjacent beams, there being two anchor members, each having a slide portion slidable on the same rod member and each having a prong upstanding towards the recess of the corner leg of the respective containers and said locking lever constitutes a plate pivotally connected to said beams and having a width substantially equal to the distance separating the two anchor members in their respective container-anchoring positions, said plate taking under gravity a locking position extending between the two anchor members, and further including spring means axially biasing said plate in centered relationship relative to said two anchor members when in their container-anchoring positions.
