Abstract

A frame assembly for shipment of dunnage includes a frame for supporting the dunnage. A bar and latch arrangement releasably secures the dunnage in the frame. The bar and latch arrangement includes a bar mounted on the frame for swinging movement in a direction toward the dunnage. A latch has a latch bolt mounted on the bar for movement from a retracted to an extended position. A rack is mounted on the frame in a position adjacent to the latch bolt when the bar is in the dunnage retaining position. The rack has a plurality of teeth aligned in the direction of bar movement. The latch bolt is engageable in any of the spaces between the teeth when the latch bolt is in its extended position to hold the bar in the dunnage retaining position.

Claims

1. A frame assembly for shipment of dunnage comprising:

a frame having means for supporting dunnage,

a bar and latch arrangement for releasably securing the dunnage in said supporting means,

said bar and latch arrangement comprising a bar,

bar mounting means mounting said bar on said frame for movement in a direction toward the dunnage in said frame to a position retaining the dunnage in said frame,

a latch comprising a latch bolt,

latch bolt mounting means mounting said latch bolt on said bar for movement from a retracted to an extended position, and

a rack mounted on said frame adjacent to said latch bolt when said bar is in the dunnage retaining position,

said rack having a plurality of teeth aligned in the direction of bar movement with spaces between said teeth,

said latch bolt being engageable in any of the spaces between said teeth when said latch bolt is in its extended position to hold said bar in the dunnage retaining position,

wherein said supporting means is adapted to support dunnage in the form of flat panels in laterally spaced generally vertical positions, and said bar extends horizontally and is mounted on said frame by said bar mounting means for swinging movement about a horizontal axis in the direction toward the panels.

2. A frame assembly according to claim 1, wherein the latch bolt mounting means includes a housing in which said latch bolt is mounted for sliding movement, spring means urging said latch bolt to its extended position, and manual means for moving said latch bolt to its retracted position.

3. A frame assembly according to claim 2, wherein said teeth have camming surfaces enabling said latch bolt to cam over said teeth during movement of said bar in the direction toward the dunnage.

4. A frame assembly for shipment of dunnage comprising:

a frame having means for supporting dunnage,

a bar and latch arrangement for releasably securing the dunnage in said supporting means,

said bar and latch arrangement comprising a bar,

bar mounting means mounting said bar on said frame for movement in a direction toward the dunnage in said frame to a position retaining the dunnage in said frame,

a latch comprising a latch bolt,

latch bolt mounting means mounting said latch bolt on said bar for movement from a retracted to an extended position, and

a rack mounted on said frame adjacent to said latch bolt when said bar is in the dunnage retaining position,

said rack having a plurality of teeth aligned in the direction of bar movement with spaces between said teeth,

said latch bolt being engageable in any of the spaces between said teeth when said latch bolt is in its extended position to hold said bar in the dunnage retaining position,

wherein said supporting means is adapted to support dunnage in the form of flat panels in vertically spaced generally horizontal positions, and said bar extends vertically and is mounted on said frame by said bar mounting means for swinging movement about a vertical axis in the direction toward the panels.

5. A frame assembly depending on claim 4, wherein the latch bolt mounting means includes a housing in which said latch bolt is mounted for sliding movement, spring means urging said latch bolt to its extended position, and manual means for moving said latch bolt to its retracted position.

6. A frame assembly according to claim 5, wherein said teeth have camming surfaces enabling said latch bolt to cam over said teeth during movement of said bar in the direction toward the dunnage.
