Abstract

Abstract Anchoring mechanism for aircraft freight decks. Normally erect anchoring devices are provided on the freight deck of an aircraft which devices will automatically yield to the passage of freight containers or pallets across same and will automatically become reerected after such have passed. There is provided in a suitable recess in the deck of the aircraft a first lever system for sensing and responding to the presence of a pallet or container and a second lever system including a hook which when desired can be caused to enter into an appropriate recess in a container for holding same snugly to such deck. Such lever systems are interconnected in such a manner that pivotal movement of the first such system against a resilient force in response to the presence of a container or pallet will automatically fold the second lever system into its retracted position and then release same for return to operating position upon the passage of such pallet or a container. A spring-loaded claw holds the second lever system normally in its operating position within the floor recess but when released permits sufficient pivotal withdrawal of the locking hooks to expose rollers mounted on vertical axes for the guidance as desired of pallets or containers without engagement therewith by the clamping hooks.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 156 words
An anchoring mechanism having a pivotal hook for engaging and anchoring freight containers to flooring in an aircraft, comprising: a two arm lever pivotally supported for movement about a first pivot axis having a bar secured to one arm and extending above the surface of said flooring, said bar having a pair of inclined contact faces for engaging a moving freight container, said moving freight container effecting a pivoting of said lever about said first pivot axis when said freight container engages said two arm lever, the other arm of said two arm lever being rotatably connected to a locking hook pivotally supported on said flooring for movement about a second pivot axis between positions above and below said surface of said flooring, said locking hook being pivotal in response to a pivoting movement of said two arm lever to effect a movement of said locking hook to a position below the surface of said flooring.
Claim 2
Dependent Claim 156 words
An anchoring mechanism having a pivotal hook for engaging and anchoring freight containers to flooring in an aircraft, comprising: a two arm lever pivotally supported for movement about a first pivot axis having a bar secured to one arm and extending above the surface of said flooring, said bar having a pair of inclined contact faces for engaging a moving freight container, said moving freight container effecting a pivoting of said lever about said first pivot axis when said freight container engages said two arm lever, the other arm of said two arm lever being rotatably connected to a locking hook pivotally supported on said flooring for movement about a second pivot axis between positions above and below said surface of said flooring, said locking hook being pivotal in response to a pivoting movement of said two arm lever to effect a movement of said locking hook to a position below the surface of said flooring.
Claim 3
Dependent Claim 90 words
An anchoring mechanism according to claim 1, wherein rollers are mounted on both sides of said locking hook in roller holders, said rollers being rotatable about vertical axes in said roller holders, said roller holders being pivotally supported for movement about horizontal axes parallel to said second pivot axis for said locking hook; wherein a catch is fixed to said locking hook and is adapted to be received in slots in said roller holders, so that said roller holders are moved in response to a pivoting of said locking hook.
Claim 4
Dependent Claim 42 words
An anchoring mechanism according to claim 1, wherein said two arm lever is under an initial tension of a spring which exerts a force on said two arm lever in the direction of an initial erected position of said two arm lever.
Claim 5
Dependent Claim 100 words
An anchoring mechanism according to claim 1, wherein said second pivot axis for said locking hook is mounted in a fork which is pivotal about said first pivot axis for said two arm lever; and including a pivotally supported claw resiliently urged into releasable engagement with said fork to hold said two arm lever and said roller holders together, said claw, when released from engagement with said fork against said resilient urging facilitating a relative movement between said locking hook and roller holder so that a nose of said locking hook will lie behind the front edge of said rollers.
