Abstract
A slide rail assembly for providing adjustable positions for fifth wheel hitches including a slide rail having feet extending downward from the underside of the slide rail, adjacent feet being separated by a detent for receiving a slide locking mechanism, each of the feet having a recesses located at the bottom inside corner of each foot, respecting the assembly. The slide rail also comprises teeth with gaps therebetween, where the gaps are vertically aligned with the recesses.
Claims15
A slide rail for providing adjustable positions for fifth wheel couplings, said slide rail having upper and lower portions, a top and a bottom, and an inboard side, said lower portion having a plurality of feet extending downward therefrom, adjacent feet being separated by a detent, and said upper portion having a plurality of guide teeth disposed longitudinally along said inboard side, comprising a recess located in a bottom inboard corner of each of said plurality of feet opening in both inboard and bottom surfaces of said feet, and wherein each of said feet are secured to a plate by applying a weld in each of said recesses.
A slide rail assembly for providing lockable, non-permanent positions for fifth wheel coupling assemblies comprising:
- a. first and second slide rails, each having an upper and a lower side, said lower side having a plurality of feet disposed generally uniformly thereon, adjacent feet being separated by a detent, each of said plurality of feet having a recess opening in an inboard and a bottom surface;
- and
- b. first and second slide rail mounting plates for mounting said first and second slide rails, respectively, onto a tractor frame and to which said feet are attached, said mounting plates being tied by a transverse member;
- and where said each of said feet of said first and second slide rails are attached to said first and second slide rail mounting plates by welding within each of said recesses.
A method for attaching a fifth wheel slide rail to a mounting substrate, said slide rail having a lower portion, and having a plurality of feet disposed along said lower portion, each of said feet having a recess in a bottom corner of each of said feet, said method comprising:
- fusing material of each of said feet within each of said recesses with material of said mounting substrate.
