Abstract
Abstract A series of wooden stakes each has a bracket mechanically secured thereto one at each of the opposite ends of the stake. The bracket includes a base and two laterally offset flanges which are spaced sufficiently from the stake to form a pocket for receiving the edges of panels between adjacent spaced stakes. The bracket includes at the upper end a cylinder welded thereto for receiving a bow which is positioned with one end in each of the oppositely facing stakes at opposite sides of the bed. At the rear of the trailer are two corner stakes each with a bracket having a flange adapted to receive a panel at the side of the flatbed and a transverse second flange for holding upright a panel at the end of the bed. The stakes, with the exception of the corner stakes, are interchangeably positionable at either side of the flatbed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A readily assembleable and disassembleable system for converting the flatbeds of trailers and trucks to low side flatbeds comprising: a plurality of removable stakes each having a mounted end of reduced size, socket means proportioned to receive the reduced size end of said removable stake therein and be vertically supported thereon, said stake including two spaced brackets each having a central portion secured to said stake, the bottom one of said brackets also forming a shoulder portion, flange means laterally offset from said central portion and defining spacings which form pockets at the upper and lower ends of said stake, and panels which are proportioned to fit within said pockets and extend between adjacent stakes to form sidewalls disposed at the edges of the flatbed.
Claim 2
Dependent Claim
125 words
A readily assembleable and disassembleable system for converting the flatbeds of trailers and trucks to low side flatbeds comprising: a plurality of removable stakes each having a mounted end of reduced size, socket means proportioned to receive the reduced size end of said removable stake therein and be vertically supported thereon, said stake including two spaced brackets each having a central portion secured to said stake, the bottom one of said brackets also forming a shoulder portion, flange means laterally offset from said central portion and defining spacings which form pockets at the upper and lower ends of said stake, and panels which are proportioned to fit within said pockets and extend between adjacent stakes to form sidewalls disposed at the edges of the flatbed.
Claim 3
Dependent Claim
149 words
A readily assembleable and disassembleable sidewall construction for the flatbed of trailers, trucks and the like, comprising a plurality of removable stakes receivable at one end thereof in spaced sockets within the siderails of the flatbed of said truck or trailer, each such stake having a reduced end to fit snugly within said pocket and having a sufficient bearing to provide a stable upright position of said stake, two spaced brackets each including a flange member adapted to be joined to said stake and having portions which are laterally spaced from the stake to define spacings forming pockets at the upper and lower ends respectively of said stake, the bottom one of said brackets also forming a shoulder portion, and panels having edges which are proportioned to fit within said pockets and extending between adjacent stakes to form sidewalls disposed along the edges of said flatbed truck or trailer.
Claim 4
Dependent Claim
149 words
A readily assembleable and disassembleable sidewall construction for the flatbed of trailers, trucks and the like, comprising a plurality of removable stakes receivable at one end thereof in spaced sockets within the siderails of the flatbed of said truck or trailer, each such stake having a reduced end to fit snugly within said pocket and having a sufficient bearing to provide a stable upright position of said stake, two spaced brackets each including a flange member adapted to be joined to said stake and having portions which are laterally spaced from the stake to define spacings forming pockets at the upper and lower ends respectively of said stake, the bottom one of said brackets also forming a shoulder portion, and panels having edges which are proportioned to fit within said pockets and extending between adjacent stakes to form sidewalls disposed along the edges of said flatbed truck or trailer.
Claim 5
Dependent Claim
34 words
The stake construction in accordance with claim 2 including a plurality of mechanical fasteners which secure said flange member to the upper and lower ends of the stake which is of hard wood construction.
Claim 6
Dependent Claim
34 words
The stake construction in accordance with claim 2 including a tubular member permanently secured to said bracket within a recess thereof whereby said tubular member is disposed at the upper end of the stake.
Claim 7
Dependent Claim
99 words
The stake construction in accordance with claim 2 including two corner stakes at the rear of the bed of the truck or flatbed trailer and adapted to provide transverse panels one at the side and one at the end of the bed, said stake including a first flanged portion adapted to form a pocket for receiving the side panel and a transverse flanged section adapted to form a pocket for the panel at the end of the bed, said flange sections being formed integrally with each other and including an interconnecting portion which is mechanically secured to said stake.
