Abstract
Abstract A device for mounting D-rings on truck trailers having permanent side extensions is described which enables the D-rings to be positioned between adjacent side extensions. The truck trailer includes a pair of outer side frame members comprised of I-Beams which extend longitudinally along the length of the trailer. A plurality of side extension members are hingedly secured at their inner ends to the top flange of each of the I-Beams. A plurality of longitudinally spaced ring supports are secured to each of the I-Beams between adjacent side extension members. A D-ring is pivotally mounted on each of the supports and may be pivoted from a vertically disposed hanging position to an upwardly and inwardly extending position adapted to have cables, straps or the like secured thereto. The rearward end of the side extension member immediately forwardly of the D-ring is cut-away or coped as is the forward end of the side extension member immediately rearwardly of the D-ring to enable the D-ring to dwell in substantially the same vertical plane as the side extension members when the side extension members are in their folded position and the D-ring is in its hanging position. The coping of the side extension members provides a means for receiving or mounting the D-rings on the I-Beam without detracting from the strength of the side extension members and without interfering with the normal operation of the side extension members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
269 words
In combination, a truck trailer comprising a wheeled frame means including at least a pair of laterally spaced apart and longitudinally extending outer side frame members; each of said frame members comprising an I-beam having horizontally disposed upper and lower flanges and a vertically disposed web extending therebetween, each of said upper flanges on said I-beams having an outer edge; and a deck means extending between the upper flanges on said I-beams, a plurality of side extension members having inner and outer edge portions, and rearward and forward ends, said side extension members being hingedly secured at their inner edge portions to the outer edges of said upper flanges on said I-beams in adjacent relation, the adjacent rearward and forward ends of adjacent side extension members including at least outer portions thereof disposed in closely spaced relation, said extension members being movable from a substantially vertically disposed folded position to a substantially horizontally disposed extension position, a plurality of longitudinally spaced load restraining supports secured to each of said I-beams between at least some of the adjacent side extension members, a load restraining ring means pivotally mounted on each of said supports and being pivotally movable from a substantially vertically disposed hanging position outwardly of said I-beam to an operative position whereby said ring means may be extended upwardly and inwardly from the outer edge of the upper flange of said I-beam, at least one of the adjacent rearward and forward ends of adjacent side extension members including a cut-away portion formed therein to accommodate pivotal movement of said load restraining ring means between said hanging and operative positions.
Claim 2
Dependent Claim
269 words
In combination, a truck trailer comprising a wheeled frame means including at least a pair of laterally spaced apart and longitudinally extending outer side frame members; each of said frame members comprising an I-beam having horizontally disposed upper and lower flanges and a vertically disposed web extending therebetween, each of said upper flanges on said I-beams having an outer edge; and a deck means extending between the upper flanges on said I-beams, a plurality of side extension members having inner and outer edge portions, and rearward and forward ends, said side extension members being hingedly secured at their inner edge portions to the outer edges of said upper flanges on said I-beams in adjacent relation, the adjacent rearward and forward ends of adjacent side extension members including at least outer portions thereof disposed in closely spaced relation, said extension members being movable from a substantially vertically disposed folded position to a substantially horizontally disposed extension position, a plurality of longitudinally spaced load restraining supports secured to each of said I-beams between at least some of the adjacent side extension members, a load restraining ring means pivotally mounted on each of said supports and being pivotally movable from a substantially vertically disposed hanging position outwardly of said I-beam to an operative position whereby said ring means may be extended upwardly and inwardly from the outer edge of the upper flange of said I-beam, at least one of the adjacent rearward and forward ends of adjacent side extension members including a cut-away portion formed therein to accommodate pivotal movement of said load restraining ring means between said hanging and operative positions.
Claim 3
Dependent Claim
37 words
The combination of claim 1 wherein the rearward end of each of the side extension members which are positioned forwardly of one of said ring means has a cut-away portion formed therein for receiving said ring means.
Claim 4
Dependent Claim
37 words
The combination of claim 1 wherein the forward end of each of the side extension members which are positioned rearwardly of one of said ring means has a cut-away portion formed therein for receiving said ring means.
Claim 5
Dependent Claim
69 words
The combination of claim 1 wherein the rearward end of each of the side extension members which are positioned forwardly of one of said ring means has a cut-away portion formed therein for receiving said ring means and wherein the forward end of each of the side extension members which are positioned rearwardly of the said ring means has a cut-away portion formed therein for receiving said ring means.
Claim 6
Dependent Claim
41 words
The combination of claim 4 wherein said ring means and said side extension members dwell in substantially the same vertical plane when said ring means is in its vertically disposed position and said side extension members are in their folded position.
Claim 7
Dependent Claim
28 words
The combination of claim 4 wherein the upper end of said ring means is disposed below the upper surface of said deck means when in its hanging position.
Claim 8
Dependent Claim
79 words
The combination of claim 1 wherein each of said supports comprises a substantially horizontally disposed first portion secured to and extending outwardly from said upper flange of the I-beam, and a second portion extending downwardly and inwardly from the outer end of said first portion, the lower end of said second portion being secured to the web of said I-beam, said ring means being pivotally secured to said support adjacent the juncture of said first and second portions thereof.
Claim 9
Dependent Claim
21 words
The combination of claim 7 wherein a reinforcing means is secured to and extends between said second portion and said I-beam.
Claim 10
Dependent Claim
