Hook latch for aircraft nacelle cowls

A latch for assembling a first and a second nacelle cowl, said latch comprising:

• a bracket able to be attached to the first cowl;
• a hooking arm comprising a hook able to cooperate with a keeper attached to the second cowl;
• a first handle rotatable relative to the bracket, between a first open configuration and a first closed configuration;
• a second handle rotatable relative to the bracket, between a second open configuration and a second closed configuration;
• the first and second handles being configured so that, in the second closed configuration, the second handle blocks the first handle in the first closed configuration,
• the latch being characterized in that, in the second closed configuration of the second handle, a shape of the second handle is fitted in a complementary shape of the first handle so as to block the first handle in the first closed configuration;
• wherein the bracket forms a housing, and the latch further comprises a sliding body housed in the housing, the sliding body being movable in translation relative to the bracket, between a first and a second axial position, the hooking arm being hinged to a first end of the sliding body;
• wherein the sliding body comprises an oblong through-hole extending between a first end and a second end;
• wherein the first handle rotates around a support rod attached to the first cowl, said rod being positioned in the oblong through-hole;
• wherein in the first closed configuration of the first handle, the first end of the through-hole is adjacent to the support rod;
• and in the first open configuration of the first handle, the second end of the through-hole is close to the support rod.

A latch for assembling a first nacelle cowl with a first cowl outer face and a second nacelle cowl with a second cowl outer face, said latch comprising:

• a bracket configured to be attached to the first cowl;
• a hooking arm including a hook configured to cooperate with a keeper attached to the second cowl;
• a first handle, rotatable relative to the bracket between a first open configuration and a first closed configuration, that includes a first trigger and a first handle plate with an outer face that forms a continuous outer face with first cowl outer face when the first handle is in the first closed configuration, the first trigger being configured to hook a first rod connected to the first cowl;
• and
• a second handle, rotatable relative to the bracket between a second open configuration and a second closed configuration, that includes a second trigger and a second handle plate with an outer face that forms a continuous outer face with first cowl outer face when the second handle is in the second closed configuration,
• wherein
• the first handle has first and second longitudinal end portions and the first longitudinal end portion defines a first shape,
• the second handle has first and second longitudinal end portions and the second longitudinal end portion defines a second shape that is complimentary to the first shape of the first handle first longitudinal end portion, and
• the first longitudinal end portion of the first handle and the second longitudinal end portion of the second handle are complimentarily engaged with one another, thereby blocking the first handle from moving from the first closed configuration to the first open configuration when the first handle is in the first closed configuration and the second handle is in the second closed configuration.
