<p>A door latch (10) comprises a follower (24) mounted for rotational movement in a latch housing (14), a guide pin (46) provided on an actuating arm (28) of the follower which is operatively linked to a multiplier (42), a bolt (12) biased outwards of the housing (14), and an inelastic flexible element (50) connected between the multiplier (42) and bolt (12). In operation, rotational movement of the follower (24) is amplified by the guide pin (46) acting on the multiplier (42). The increased rotational movement of the multiplier (42) is converted to rectilinear movement of the bolt (42) into the housing (14) by the inelastic flexible element (5 0), which wraps around an outside edge (47) of the multiplier (42).</p> |
