US 6,371,424 B1 · Mounting an article upon a support

Abstract

A mounting for mounting an article onto a support comprising upper and lower mounting members. Seating surfaces provided between the members retain the members in assembled relationship with the members immovably registered together in a first plane. Three spaced mounting member registration projections provide, in the assembly, contact between the mounting members in three spaced and staggered positions on opposite sides of one of the mounting members, and registration to hold the members immovably together in a second plane. Spring-loaded locking is provided to hold the members together when assembled. Preferably the registration projections are provided on one member upon guide surfaces which are converging and inclined towards a respective seating surface. Guide surfaces on the other member are correspondingly converging and inclined. The convergence and inclination causes the projections to force the seating surfaces together to hold the members in the first plane while the projections themselves hold the members together in the second plane. One or other of the seating surfaces may have seating projections to engage the other seating surface. The invention is particularly applicable for use on weapons for withstanding sudden violent or vibrational forces and for quick release while permitting reassembly and while ensuring that settings such as calibration and boresighting settings are not altered.

Dependent claims

A mounting for mounting an article upon a support comprising:

first and second mounting members which are relatively movable into assembled relationship in which the second mounting member is held in a seating position by the first mounting member, each mounting member having a seating means, the seating means of the two mounting members lying in abutting relationship with the second mounting member immovably registered in a first plane relative to the first mounting member when the second mounting member is in the seating position, the mounting also comprising three spaced mounting member registration projections which are located to provide, in the seating position, contact between the mounting members in a three spaced position and staggered relationship from side to side of the second mounting member to register the second mounting member in a second plane relative to the first mounting member, the registration projections providing wiping action between the mounting members during their movement into assembled relationship;
and
means for locking the mounting members together with the second mounting member remaining in the seating position,
wherein the locking means comprises a plurality of locking arms carried by one of the mounting members, each arm being spring-urged to move it into a position of locking engagement with the other mounting member when the second mounting member is in its seating position,
and wherein there are two locking arms carried by the first mounting member and pivotable about pivot axes, respectively, to engage opposing sides of the second mounting member when the second mounting member is in its seating position.

and
means for locking the mounting members together with the second mounting member remaining in the seating position,
wherein the locking means comprises two locking arms carried by the first mounting member and pivotable about pivot axes, respectively, each locking arm being spring-urged into a position of locking engagement with the second mounting member when the second mounting member is in its seating position, each locking arm being engagable in a respective slot defined in the second mounting member to engage a side of the slot and hold the second mounting member in its seating position,
each locking arm has a latch end portion for engaging said side of the slot and the configuration and dimensioning of each latch end portion and its associated slot, and the position of the pivot axis, are such that, in use, any component of force tending to move the locking arm outwards from its locking position resulting from a force acting parallel to a direction of said movement into assembled relationship is less than the effect of friction between the latch end portion and the associated slot side and the action of the spring.

and
means for locking the mounting members together with the second mounting member remining in the seating position,
wherein the first mounting member has a base and two side flanges extending in opposition to each other from the base to defme with the base a receiving channel for the second mounting member, the base having a seating surface of the seating means facing into the channel, and the flanges having inwardly turned free ends which provide a first pair of guide surfaces which converge in a direction away from an entrance to the channel for receiving the second mounting member, the surfaces of the first pair being inclined, in a lateral direction, towards the seating surface of the first mounting member, the second mounting member having a seating surface of the seating means for abutting contact with the seating surface of the first mounting when the second mounting member is in the seating position, the second mounting member having a second pair of guide surfaces which converge and are inclined correspondingly to the first guide surfaces and each registration projection being provided as part of a respective guide surface whereby during movement of the two mounting members into assembled relationship, each guide surface of one pair moves longitudinally and laterally of a corresponding guide surface of the other pair until, with the second mounting member in its seating position, each of the registration projections on its respective guide surface engages a corresponding guide surface with the inclination of the guide surfaces retaining the abutting contact of the seating means to immovably register the second mounting member in the first plane,
and further comprising a pair of locking arms each pivotally mounted upon a respective flange of the first mounting member, the locking arms being spring urged to move through a slot in a respective flange and into another slot provided in the second mounting member so as to hold the second mounting member in its seating position.
