  • Mechanical shock absorber
    Patent number: 4396096
    Abstract: A shock absorber for attenuating a shock effect between a fixed point and a movable element which comprises a casing, a threaded element mounted for axial movement within the casing, and a first engagement member and a second engagement member mounted for rotary and axial movement within the casing in response to a shock effect, the first engagement member being in normal contact engagement with the threads of the threaded element for converting the axial movement of the threaded member into a rotary movement of the second engagement member and the second engagement member being adapted to engage the threads of the threaded element, whereby upon the application of the shocking effect above a predetermined amount, the second engagement member abuts against the threads of the threaded element to block further rotational movement of the second engagement member by becoming lockingly engaged with the threads of the threaded element while the shocking force is applied thereto.
