Stake post and cap arrangement for trailer

Claim 2

For a highway vehicle having a removable cargo container including a tarpaulin roof supported thereabove by tarpaulin bows, a vertical extending hollow stake adapted to carry a tarpaulin bow and having both a vertically extending stake bow portion and a vertically extending groove formed in its interior, and a protector cup extendable over said stake and having a fastening portion extending downward therefrom and couplable with the groove on the interior of said hollow stake, said cap having a cap bow socket portion depending therefrom so as to be vertically slidably coupled and coopertive with the stake bow socket portion to define a continuous bow receiving socket for receiving a bow extending through said protector cap and into the hollow stake, said stake bow socket portion having outer edge portions and said cap bow socket portion having outer edge portions interlocking in anti-rotational fashion with the outer edge portions of the stake bow socket portion consequent upon vertical sliding coupling of the cap bow socket portion with respect to the stake bow socket portion.

Claim 3

The invention according to claim 1, and said cup having a plate-like upper portion with a bow receiving bore defined therein above said cap bow socket portion and in communication therewith for receiving the bow through the cap bore and into the bow receiving socket.

Claim 4

The invention according to claim 1, and said hollow stake including an inboard stake member having a longitudinally extending inboard wall portion, and an outboard stake member including a longitudinally extending outboard wall portion spaced from said inboard wall portion, a pair of transverse side walls, and a pair of spaced longitudinal wall portions extending from the transverse side walls and couplable with said inboard wall portion.

Claim 5

For a highway vehicle having a removable cargo container including tarpaulin roof supporting bows; a vertically extending hollow stake including longitudinally spaced transverse wall portions, inboard and outboard longitudinal wall portions extending between said transverse wall portions and a vertically extending stake bow socket portion formed on the interior of the outboard longitudinal wall intermediate said transverse wall portions, and a replaceable stake protector cap adapted to overlie the stake and including a cap bow socket portion depending from the protector cap into the stake between said stake bow socket portion and said inboard longitudinal wall portion for vertical sliding coupling with said stake bow socket portion to define a vertically extending bow socket for receiving and supportably coupling a tarpaulin bow portion extendable through the protector cap, said stake bow socket portion having outer edge portions, and said cap bow socket portion having outer edge portions interlocking in anti-rotational fashion with the outer edge portions of the stake bow socket portion consequent upon vertical sliding coupling of the cap bow socket portion with respect to the stake bow socket portion preventing destructive rotational oscillation between the bow, protector cap and the stake.

Claim 6

For a highway vehicle having a removable cargo container including tarpaulin roof supporting bows; a vertically extending hollow stake including longitudinally spaced transverse wall portions, inboard and outboard longitudinal wall portions extending between said transverse wall portions and a vertically extending stake bow socket portion formed on the interior of the outboard longitudinal wall intermediate said transverse wall portions, and a replaceable stake protector cap adapted to overlie the stake and including a cap bow socket portion depending from the protector cap into the stake between said stake bow socket portion and said inboard longitudinal wall portion for vertical sliding coupling with said stake bow socket portion to define a vertically extending bow socket for receiving and supportably coupling a tarpaulin bow portion extendable through the protector cap, said stake bow socket portion having outer edge portions, and said cap bow socket portion having outer edge portions interlocking in anti-rotational fashion with the outer edge portions of the stake bow socket portion consequent upon vertical sliding coupling of the cap bow socket portion with respect to the stake bow socket portion preventing destructive rotational oscillation between the bow, protector cap and the stake.

Claim 7

The invention in accordance with claim 4,and said stake comprising inboard and outboard sections with vertically slidably couplable means provided on each section for interlocking said sections, and means fixedly interconnecting said cap bow socket portion with said inboard section to further interlock said inboard section to said outboard section through said stake bow socket portion.

Claim 8

The invention in accordance with claim 5, and said protector cap having a top web positioned in covering relation to the stake and a pair of lugs depending from said top web into said stake in abutting relation to the interior sides of the transverse wall portions thereof.
