Abstract
An anchor fitting assembly for attaching a full width partition, having a door opening, to the fuselage structure of an airplane for dividing a passenger area into two or more compartments. During installation of the partition, provisions are made to allow the lower attachments, of the partition to the seat tracks in the floor of the compartment, to have a certain amount of freedom of movement in both the inboard/outboard and up/down directions. This floating action in the attachment is required for absorbing fuselage deflections due to flight loads imposed on the floor beams and in some cases due to torsional deflections of the wing torque box to which the seat track is fixedly attached, in order to maintain a square door opening.
Claims8
An attach fitting assembly for installing a removable article in the interior of an aircraft fuselage having a seat track structurally attached to the floor of the fuselage, said attach fitting assembly comprising:
- said seat track defining an inverted T-slot channel member, having sequentially spaced circular cut-outs in the upper surface thereof;
- a foot member defining an elongated base contoured for insertion into said seat track and to be slid along in said track a distance half-way between two adjacent circular openings for vertical retention thereby;
- said foot member having an upright T-rail section aligned with said elongated base and structurally integral therewith, for extending above said seat track when the base of said foot member is inserted into said seat track;
- a retainer contoured for insertion into one of the circular openings in said seat track and having an undersurface for mating with the base of said foot member, for locking said foot member against sliding motion in said seat track;
- an attach angle defining a base member and an upright boss;
- said attach angle base member having a slot therein for slidably engaging said raised T-rail section of said foot member and being retained thereby against vertical movement;
- means inserted through said attach angle, said retainer and threadably engaging said foot member, for clamping these three components tightly to the seat track;
- a receptacle being fixedly attached to said article and adapted for engaging said upright boss for connecting said article to the floor of the aircraft fuselage.
Apparatus for installing a removable partition in the fuselage of an aircraft, comprising:
- seat tracks defining a plurality of laterally spaced and substantially parallel longitudinally, inverted T-slot channel members, having sequentially spaced circular cut-outs in the upper surface thereof, and being secured to the floor of the aircraft fuselage;
- said partition extending transversely in the interior of the fuselage forming a separator, and having an inverted U-shape channel defining the lower edge thereof;
- anchor fitting assemblies interposed between said partition lower edge portion and said seat tracks for forming a connecting means therebetween;
- one of said anchor fitting assemblies comprising a foot member, a retainer, an attach angle and a receptacle;
- said foot member defining an elongated base contoured by having sequentially spaced circular protrusions for matching insertion into said seat track and to be slid along in said track a distance half-way between two adjacent circular openings for vertical retention thereby;
- said foot member having an upright T-rail section aligned partially with the length of said elongated base and structurally integral therewith, for extending above said seat track when the base of said foot member is inserted into said seat track;
- said retainer being contoured for insertion into one of the circular openings in said seat track and having an undersurface for mating with the remaining length of the base of said foot member, for locking said foot member against sliding motion in said seat track;
- said attach angle defining a base member and an upright boss;
- said attach angle base member having a slot therein for slidably engaging said raised T-rail section of said foot member and being retained thereby against vertical movement;
- means inserted through said attach angle, said retainer and threadably engaging said foot member, for clamping these three components tightly to the seat track;
- said receptacle being contoured for mating insertion into the inverted U-shaped channel defining the lower edge of said partition and being fixedly attached thereto;
- and said receptacle being adapted for engaging said upright boss for restraining said article against longitudinal movement relative to the floor of the aircraft fuselage.
