Abstract: 1,200,243. Stud and socket fastenings. ENGLISH STEEL CORP. Ltd. 15 Jan., 1969 [16 Jan., 1968], No. 2263/68. Heading E2B. A fastening device for attachment to a vehicle in a position for engagement of a fastening projection 13 by a corner fitting of a freight container to be carried on a support surface of the vehicle comprising a body 1 for securing to 'the vehicle and housing a fixed guide 4 within which a fastening member 12 which includes the fastening projection 13 is rotatable and axially slidable, a spring 21 urging the fastening member outwardly of the body, a handle 10 secured to the fastening member and extending laterally of a slot in the body having three portions, the first portion 11A being perpendicular to the axis of the fastening member and subtending an angle capable of allowing swing of the handle between fastening and releasing positions, the second portion 118 extending axially from the fastening position of the handle in the opposite direction to the urge of the spring on the fastening member and the third portion 11C being a hook like-end portion on the second portion to retain the handle after it has been moved through the second portion to bring the fastening member against the spring urge completely into the body. In the construction shown the projection 13 is a non-circular head of the fastening member which in the releasing position can pass through a correspondingly shaped hole in the bottom of the corner fitting and the fastening member extends through a collar 15 which is also of corresponding shape to the head to maintain the alignment of the corner fitting and the fastening device when the head has been rotated out of alignment with the hole in the corner fitting to secure the container to the vehicle. The collar is provided on the plate 16 slidable in but non-rotatable with respect to the body and abutting a shoulder of the fastening member facing the head so as to be urged outwardly of the body by the spring with the fastening member. The collar and plate are either formed in two halves welded together and placed below the head or alternatively the head is formed separately from the rest of the fastening member and welded or pinned to it after fitting a one piece said collar and plate. The plate has a pip 17 on one side slidable in a groove in the body to prevent rotation of the collar with respect to the body. The fastening member has two flanged abutments 24, 25 spaced axially, the abutment nearer the head 13 being non-circular and disposed so as to be aligned with a correspondingly shaped opening 26 in the guide 4 when the handle 10 is in the fastening position; the other abutment 25 is also formed to correspond with the opening 26 in the guide 4 but disposed so as to be aligned therewith when the handle 10 is in the releasing position whereby the member '12 can befitted through the guide 4 against the urge of the spring 21 before the handle 10 is screwed in place in the member 12. A gravity latch 27 is provided to prevent accidental movement of the handle 10 from the fastening position.
