Abstract
Abstract In means for securing a freight container to the platform of a vehicle a Tee-headed spindle axially movable between projected and retracted positions in a housing and angularly movable between fastening and releasing positions passes through an element mounted on the spindle for axial movement therewith and movable with the spindle into and out of a position in which it holds the spindle in the projected position, the spindle being movable angularly independently of the said element between the fastening and releasing positions.

Claim 1
Independent Claim

Means for releasably securing a freight container to a platform of a vehicle comprising a Tee-headed spindle which is axially and rotatabLy movable in a housing, the spindle being axially movable between a projected position in which the head is adapted to enter a non-circular opening in the base of a corner casting of a container placed on the platform and a retracted position in which the head does not project above the surface of the platform, and the spindle also being rotatably movable between a fastening position in which the head engages with the corner casting and a releasing position in which the head can pass freely through the opening in the casting, the invention comprising an element mounted on said spindle, so as to secure said element to said spindle for axial movement therewith between its projected and retracted positions, releasable means connecting said element with said spindle for rotatable movement therewith, said element including means engaging portions of said housing upon rotation of said spindle in its projected position whereby said element is releasably held against rotation relative to said housing and said spindle is held in its projected position said releasing means being constructed and arranged that when said element is in its holding position said spindle is rotatable independently of said element between fastening and releasing positions.

Means for releasably securing a freight container to a platform of a vehicle comprising a Tee-headed spindle which is axially and rotatabLy movable in a housing, the spindle being axially movable between a projected position in which the head is adapted to enter a non-circular opening in the base of a corner casting of a container placed on the platform and a retracted position in which the head does not project above the surface of the platform, and the spindle also being rotatably movable between a fastening position in which the head engages with the corner casting and a releasing position in which the head can pass freely through the opening in the casting, the invention comprising an element mounted on said spindle, so as to secure said element to said spindle for axial movement therewith between its projected and retracted positions, releasable means connecting said element with said spindle for rotatable movement therewith, said element including means engaging portions of said housing upon rotation of said spindle in its projected position whereby said element is releasably held against rotation relative to said housing and said spindle is held in its projected position said releasing means being constructed and arranged that when said element is in its holding position said spindle is rotatable independently of said element between fastening and releasing positions.
Claim 3
Dependent Claim
57 words
Means as in claim 1 wherein said element comprises a collar, said releasable means comprising resilient detent means normally constraining said collar to rotate with the spindle and being constructed and arranged to yield and allow the spindle to be rotated independently of the collar when the latter is in engagement with said portions of the housing.
Claim 4
Dependent Claim
41 words
Means as in claim 1 wherein said element is rotated with the spindle into the position in which its holding means engages with said portions of the housing upon rotation of the spindle to bring the head into the fastening position.
Claim 5
Dependent Claim
54 words
Means as in claim 1 wherein said element rotates with the spindle to bring its holding means out of engagement with said portions of the housing upon rotation of the spindle to bring the head from the fastening position into the releasing position whereby the spindle and head then drop into the retracted position.
Claim 6
Dependent Claim
44 words
Means as in claim 1 wherein the holding means of said element comprise a stepped part engaging with said portions of the housing for normally holding the element against angular movement and is disengaged by axial movement of the spindle in the projecting direction.
Claim 7
Dependent Claim
38 words
Means as in claim 1 wherein said spindle extends downwardly through the lower end of the housing and a handle is mounted in the part of the spindle below the housing for moving the spindle axially and rotatably.
