Abstract
Abstract A trailer bed having paired retractable fasteners to hold the rim of a container placed thereon from rolling off or bouncing off while the trailer is pulled across a field. A fastener includes a shoulder element which is rotatably mounted to the bed and can be retracted to a position below the surface of the bed by use of a pull rod. The shoulder element abuts against the edge of the container lip to prevent longitudinal movement of the container from the bed. A tongue element is rotatably mounted to the shoulder element and includes a latching tongue that extends out through an opening in the shoulder. When the shoulder element is rotated to a retracted position, the tongue element pivots within the shoulder element and also retracts to below the container bed so that the container itself can be rolled on or off the bed. When protracted, the tongue element extends out an opening in the shoulder and over the lip of the container to hold the container from bouncing up off the bed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
212 words
On the bed of a baggage cart, the container stop and hold down mechanism improvement comprising: a first element roTatably mounted on said bed and having a first end position extending above the surface of said bed and a second end position entirely below the surface of said bed, a spring connected between said element and said bed to bias said element into said first end position, said first element having a shoulder extending up from said bed in a substantially vertical direction when said element is in said first end position, a second element rotatably mounted on said first element and having a first end position extending above the surface of said bed and a second end position entirely below the surface of said bed, said second element including a tongue portion positioned to extend over the lip of a container abutting against said shoulder when said first element and said second element are both in their said first end positions, constraint means engaging said second element to force said second element into its said first end position when said first element is in its said first end position and to force said second element into its said second end position when said second element is in its said second position.
Claim 2
Dependent Claim
212 words
On the bed of a baggage cart, the container stop and hold down mechanism improvement comprising: a first element roTatably mounted on said bed and having a first end position extending above the surface of said bed and a second end position entirely below the surface of said bed, a spring connected between said element and said bed to bias said element into said first end position, said first element having a shoulder extending up from said bed in a substantially vertical direction when said element is in said first end position, a second element rotatably mounted on said first element and having a first end position extending above the surface of said bed and a second end position entirely below the surface of said bed, said second element including a tongue portion positioned to extend over the lip of a container abutting against said shoulder when said first element and said second element are both in their said first end positions, constraint means engaging said second element to force said second element into its said first end position when said first element is in its said first end position and to force said second element into its said second end position when said second element is in its said second position.
Claim 3
Dependent Claim
158 words
The improvement of claim 1 wherein: said second element has a leg portion connected to said tongue portion, said constraint means comprises first and second pins mounted to said bed, said leg portion of said second element positioned between said pins, said second element being rotatably mounted to said first element along a line between said leg portion and said tongue portion, the pivot line of said second element on said first element being offset from the pivot line of said first element on said bed, rotation of said first element causing rotation of second element relative to said first element due to the constraint imposed by said pins on said leg portion, said leg portion being free to slide between said pins, the length of said leg portion being sufficient to retain said leg portion between said pins when said second element is in said first end position and when second element is in said second position,
Claim 4
Dependent Claim
53 words
The improvement of claim 1 wherein: the axis of rotation of said first element relative to said bed and the axis of rotation of said second element relative to said first element being horizontal and parallel to one another, and said first and second pins, each being parallel to said axes of rotation.
Claim 5
Dependent Claim
53 words
The improvement of claim 2 wherein: the axis of rotation of said first element relative to said bed and the axis of rotation of said second element relative to said first element being horizontal and parallel to one another, and said first and second pins, each being parallel to said axes of rotation.
