Abstract
A pivoting adjustment screw for mounting the bolt of a latch to provide vibrational damping along with increasing preload as the contact point of the adjustment screw to the mating structure shifts in a shock or vibrational environment. The adjustment screw includes a pivoting portion which permits the screw to pivot which allows a rotating rather than a scraping or abrading movement in response to the relative movement between the elements being connected.
Claims21
An adjustment screw for mounting on a first member to abut against a second member comprising:
- a housing insertable within a first member and having an inner rim forming a first and second seat;
- a bolt positionable within the housing and having a head, a threaded end, and a shoulder between the head and the threaded end, the bolt shoulder facing the threaded end of the bolt;
- a sleeve on the bolt with one end adjacent the bolt shoulder, the sleeve having a shoulder facing the threaded end of the bolt;
- a first spherical washer on the sleeve with a first end abutting the sleeve shoulder and a spherical second end facing the threaded end of the bolt;
- a second spherical washer positioned in the first seat of the housing and having a spherical end engaging the spherical second end of the first spherical washer;
- and
- a nut threaded onto the threaded end of the bolt adjacent the second seat of the housing.
An adjustment screw for mounting on a first member to abut a second member comprising:
- a housing insertable within a first member and having an inner rim forming a first and second seat;
- a bolt positioned within the housing and having a head on one end of the bolt facing the first seat, a threaded end adjacent the second seat, and a shoulder between the head and the threaded end, the bolt shoulder facing the threaded end of the bolt;
- a sleeve on the bolt with a first portion abutting the bolt shoulder and a second portion with a spherical end facing the threaded end of the bolt;
