Abstract
Abstract A store carrier supports a store from two store lugs. The store is supported from a substantially central point with one end of each of a pair of hooks being pivotally mounted to a carrying vehicle such as an aircraft, and the other end of each hook being linked to a latch means. A reaction force necessary to activate the hooks is related to a downward force applied thereto by the store. Clamps are provided at each suspension hook to urge each store lug against a portion of the vehicle structure to eliminate sway in the store. A thruster means is positioned adjacent the store to impart downward force to the store when released from the suspension hooks. Propellent means are provided for unlocking the latch of each hook, to activate the suspension hooks and the thruster means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
A store carrier for mounting a jettisonable store on an aircraft and for releasing the store with ejective force, the store having at least two inverted U-shaped lugs connected thereto, comprising: a store carrier frame; suspension hooks adapted for engagement with said inverted Ushaped lugs, each of said suspension hooks including a long arm, a short arm, a central body portIon and opposite side faces, said inverted U-shaped lugs being supported in a vertical direction on said short arms; wedge means disposed adjacent the opposite side faces of said hooks and acting generally horizontally to restrain swaying movements of the inverted U-shaped lugs of the store; means for pivotally mounting said central body portion to said store carrier frame; linkage means mounted to said store carrier frame for supporting the long arm of said suspension hooks, such that approximately one-half of the weight on said short arm is supported by said linkage means and the other half is supported by said pivotal mounting means; and activating means operatively coupled to said linkage means activating said linkage means to cause said suspension hooks to pivot with respect to said carrier to release the lugs.
Claim 2
Dependent Claim
193 words
A store carrier for mounting a jettisonable store on an aircraft and for releasing the store with ejective force, the store having at least two inverted U-shaped lugs connected thereto, comprising: a store carrier frame; suspension hooks adapted for engagement with said inverted Ushaped lugs, each of said suspension hooks including a long arm, a short arm, a central body portIon and opposite side faces, said inverted U-shaped lugs being supported in a vertical direction on said short arms; wedge means disposed adjacent the opposite side faces of said hooks and acting generally horizontally to restrain swaying movements of the inverted U-shaped lugs of the store; means for pivotally mounting said central body portion to said store carrier frame; linkage means mounted to said store carrier frame for supporting the long arm of said suspension hooks, such that approximately one-half of the weight on said short arm is supported by said linkage means and the other half is supported by said pivotal mounting means; and activating means operatively coupled to said linkage means activating said linkage means to cause said suspension hooks to pivot with respect to said carrier to release the lugs.
Claim 3
Dependent Claim
48 words
The invention according to claim 1 wherein said suspension hooks include projections which extend out from the opposite side faces thereof and said wedge means include indented portions whereby said projections extend into said indented portions of wedge means to restrict the vertical movement of said wedge means.
Claim 4
Dependent Claim
77 words
The invention according to claim 1 wherein each of said suspension hooks includes a projection which extends upwardly therefrom and said wedge means include pairs of wedge members disposed adjacent the opposite side faces of said hooks, each pair of wedge members including a spring member therebetween, said spring members cooperating with said projections of said hooks to raise said wedge members into lug engagement positions as said hooks engage the inverted U-shaped lugs of the store.
Claim 5
Dependent Claim
42 words
The invention according to claim 3 wherein said wedge members include engagement faces for engagement with the inverted U-shaped lugs of the store, each engagement face being contoured to contact a substantial portion of the side of the adjacent inverted U-shaped lug.
Claim 6
Dependent Claim
183 words
An aircraft store carrier for mounting a store jettisonable in a predetermined direction having a predetermined number of inverted U-shaped lugs connected thereto comprising: a frame; hooks for engagement with the inverted U-shaped lugs of the store, said hooks each including a lower arm portion, a central body portion, an upper arm portion generally parallel to said lower arm, and first and second side portions, each hook being pivotally mounted at the body portion thereof to said frame for rotation in a plane parallel to said first side portion for engagement and disengagement with an inverted U-shaped lug; wedge means disposed adjacent said first and second side portions of each hook for acting generally at right angles to the predetermined jettison direction against the inverted U-shaped lugs engaged by said hooks to restrain swaying movements of the inverted U-shaped lugs and the store connected thereto; linkage means connected to the upper arm portions of said hooks; and activating means operatively coupled to said linkage means for activating said linkage means to cause pivotal movement of said hooks to disengage the inverted U-shaped lugs.
Claim 7
Dependent Claim
183 words
An aircraft store carrier for mounting a store jettisonable in a predetermined direction having a predetermined number of inverted U-shaped lugs connected thereto comprising: a frame; hooks for engagement with the inverted U-shaped lugs of the store, said hooks each including a lower arm portion, a central body portion, an upper arm portion generally parallel to said lower arm, and first and second side portions, each hook being pivotally mounted at the body portion thereof to said frame for rotation in a plane parallel to said first side portion for engagement and disengagement with an inverted U-shaped lug; wedge means disposed adjacent said first and second side portions of each hook for acting generally at right angles to the predetermined jettison direction against the inverted U-shaped lugs engaged by said hooks to restrain swaying movements of the inverted U-shaped lugs and the store connected thereto; linkage means connected to the upper arm portions of said hooks; and activating means operatively coupled to said linkage means for activating said linkage means to cause pivotal movement of said hooks to disengage the inverted U-shaped lugs.
Claim 8
Dependent Claim
66 words
The store carrier defined in claim 5 wherein said wedge means include: a pair of wedge members juxtaposed to side portions of at least two of said hooks; and spring members connected between the wedge members of each pair, said spring members cooperating with said hooks to urge said wedge members into lug engaging positions as said hooks are pivoted to engage the inverted U-shaped lugs.
Claim 9
Dependent Claim
51 words
The store carrier defined in claim 5 wherein said wedge means include a pair of wedge members juxtaposed the side portions of at least two of said hooks, and said hooks include means for loose engagement with said wedge members to restrain said wedge members to a predetermined range of movement.
