<p>A latch assembly having a latch body (12) adapted to be coupled to a generally fixed support, such as a chassis unit, wall or post. The latch body (12) has a groove (44) for removably receiving a retained pin (14) which is adapted to be mounted on a movable structural member to be latched, such as a door, support arm, gate or the like. The latch body (12) further includes a latch pin (16) which is spring biased into engagement with the retained pin (14) when the retained pin is received in the groove (44) of the latch body. The inter-engagement of the retained pin (14) and latch pin (16) is such that the retained pin is restricted against movement in three mutually perpendicular directions, namely the x, y and z directions. The retained pin (14) has a pair of spaced, cylindrical parts (48) on opposite sides of a pair of bevelled parts (49,50) which converge toward each other to an annular junction (51) therebetween. The latch pin has a conical end portion (39) for engaging the bevelled parts (49,50) of the retained pin to resist axial movement of the retained pin in the z direction. The engagement of the cylindrical parts (48) of the retained pin (14) with the surfaces of the latch body (12) defining the groove (44) resists movement of the retained pin in a pair of mutually perpendicular directions, namely the x and y directions.</p> |
