  • Patent number: 8740147
    Abstract: The invention relates to a pressure relief latch for aircraft, able to absorb vibrations and shocks without inopportune opening, as well as to adapt to dimensional stresses during its assembly. The latch includes: a console, a lever mounted on the console, and an opening effort exerted on a fulcrum of the lever causing an angular displacement of the fulcrum between a closing position and an opening position. The latch also includes a roller able to roll against a profile of the lever and connected to an elastic return device. The latch further being provided with means able to vary the angular displacement of the fulcrum of the lever according to the opening effort, with two different slopes according to an opening effort E1.

  • Patent number: 8448929
    Abstract: The invention relates to a riveting tack (50) to be introduced into coaxial openings of at least two elements to be assembled, and comprising a hollow cylindrical body (51), a rod (53) passing through the hollow body and partially provided with an external thread (52a), a nut (54) mounted on the threaded end (53a), two half-clips (56) fixed to the rod (53) and comprising hooking lips (57) on the ends thereof, and a spacer (58) arranged between the two half-clips (56), the rod/half-clip set being axially mobile along the spacer (58) between a first position wherein the hooking lips (57) are radially close, and a second position wherein the two half-clips (56) are retracted inside the hollow body (51) and radially distanced from each other. The invention is characterized in that the set formed by the half-clips (56) and the spacer (58) is, in the cross-section thereof, in the form of a near-perfect circle having a diameter identical to the inner diameter of the openings.

  • Publication number: 20130043350
    Abstract: The invention relates to pressure relief latch for aircraft, able to absorb vibrations and shocks without inopportune opening, as well as to adapt to dimensional stresses during its assembly. The invention thus refers to a pressure relief latch including: a console (31); a lever (34) mounted on the console, an opening effort (E) exerted on a fulcrum (46) of the lever causing an angular displacement (D) of said fulcrum between a closing position and an opening position, a roller (37) able to roll against a profile (36) of the lever and connected to an elastic return device (42), the latch being provided with means (47, 48) able to vary the angular displacement (D) of the fulcrum of the lever according to the opening effort, with two different slopes according to an opening effort E1.
