Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 204 words
A floor latch strip for use in a freight-carrying vehicle equipped with a lading separator carrying downwardly projecting latch elements, said floor latch strip comprising, an elongated body formed of two bars each having an M-shaped transverse cross section, said bars being positioned longitudinally of the vehicle to form with the vehicle upper and lower longitudinally extending channels, with the bottom of said upper channel being defined by spaced apart horizontally extending portions of said bars and said lower channel being defined by spaced apart vertically extending portions of said bars, a keeper fixedly secured to said two bars and extending substantially the entire length thereof, the bottom of said keeper being secured to said lower channel and sealing said lower channel from said upper channel, said keeper having a plurality of locking slots therein for cooperating with the latch elements to latch the lading separators in place, the bottom of said slots lying in the same plane as the horizontally extending surfaces of said upper channel, whereby said upper channel is readily cleanable due to the alignment of said slots with said upper channel and said lower channel is prevented from being filled with debris due to the sealing thereof by said keeper.
Claim 2
Dependent Claim 204 words
A floor latch strip for use in a freight-carrying vehicle equipped with a lading separator carrying downwardly projecting latch elements, said floor latch strip comprising, an elongated body formed of two bars each having an M-shaped transverse cross section, said bars being positioned longitudinally of the vehicle to form with the vehicle upper and lower longitudinally extending channels, with the bottom of said upper channel being defined by spaced apart horizontally extending portions of said bars and said lower channel being defined by spaced apart vertically extending portions of said bars, a keeper fixedly secured to said two bars and extending substantially the entire length thereof, the bottom of said keeper being secured to said lower channel and sealing said lower channel from said upper channel, said keeper having a plurality of locking slots therein for cooperating with the latch elements to latch the lading separators in place, the bottom of said slots lying in the same plane as the horizontally extending surfaces of said upper channel, whereby said upper channel is readily cleanable due to the alignment of said slots with said upper channel and said lower channel is prevented from being filled with debris due to the sealing thereof by said keeper.
Claim 3
Dependent Claim 43 words
The floor latch strip set forth in claim 1, wherein the uppermost portion of each of said M-shaped bars is constructed and arranged sealingly to engage the vehicle floor to prevent debris from falling on the vehicle floor below the elongated M-shaped bars.
Claim 4
Dependent Claim 64 words
The floor latch strip set forth in claim 1, wherein each of said M-shaped bars has two flanges disposed at substantially right angles one to the other, said right angle flanges being constructed and arranged to seal with a portion of the vehicle thereby to prevent debris from falling into a longitudinally extending channel formed by the two M-shaped bars and the vehicle floor.
Claim 5
Dependent Claim 64 words
The floor latch strip set forth in claim 1, wherein each of said M-shaped bars has two flanges disposed at substantially right angles one to the other, said right angle flanges being constructed and arranged to seal with a portion of the vehicle thereby to prevent debris from falling into a longitudinally extending channel formed by the two M-shaped bars and the vehicle floor.
Claim 6
Dependent Claim 55 words
The floor latch strip set forth in claim 1, wherein said keeper includes two laminated bars extending longitudinally of the vehicle and fitting within the lower channel formed by said M-shaped bars, said keeper being maintained within said M-shaped bars by means of a plurality of rivets extending through said keeper and said M-shaped bars.
Claim 7
Dependent Claim 55 words
The floor latch strip set forth in claim 1, wherein said keeper includes four laminated bars extending longitudinally of the vehicle and fItting within the lower channel formed by said M-shaped bars, said keeper being maintained within said M-shaped bars by means of a plurality of rivets extending through said keeper and said M-shaped bars.
