Abstract
Abstract A tiedown device for trailers having a channel anchored to the ground, two bolts rising from one flange of the channel and supported thereon, the bolts adjustably supporting at their upper ends an angle iron brought to underlie the fore and aft I-beam of the trailer; the bolts passing the I-beam and having hold-down plates clamped by nuts on the bolts over the feet of the I-beam, thus holding the I-beam and the trailer against forces of either tension or compression applied to the bolts. There is a square headed and shank strap tension bolt extending through the flanges of the channel at the bottom to engage the end of a strap which extends around the trailer and down to a similar bolt at the tiedown on the opposite side of the trailer. The strap can be tensioned by moving the bolt axially to displace a squared part of the bolt shank from a squared hole in the channel, so that the bolt can be turned to tighten the strap. When tight, the bolt shank is again displaced axially to dispose its squared part in the squared hole and to prevent unwinding of the strap. Holes are provided for turnbuckles and cross members that can crisscross beneath the trailer to prevent it from being twisted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A tiedown mechanism for trailers, mobile homes and the like that have flanged beams on their undersides, comprising: a base member to be secured to the ground below a flanged beam, the base member having means by which it may be secured to the ground; attaching means comprising a pair of rods secured to the base member and extending upwardly therefrom toward the bottom of the trailer; a plate adapted to be held against a beam on the underside of the trailer, the plate having openings through which the ends of the rods project; means to hold the plate on the rods against the underside of the beam; the plate being dimensioned so that the rods extend above the opposite sides of the beam and alongside the flanges on the beam; means to overlie the flanges, said means being secured to ends of the rods above the plate and means on the ends of the rods clamping the overlying means against the flanges on opposite sides of the beam and the plate to holD the flanges against upward, lateral or downward movements relatively to the beam.
Claim 2
Dependent Claim
186 words
A tiedown mechanism for trailers, mobile homes and the like that have flanged beams on their undersides, comprising: a base member to be secured to the ground below a flanged beam, the base member having means by which it may be secured to the ground; attaching means comprising a pair of rods secured to the base member and extending upwardly therefrom toward the bottom of the trailer; a plate adapted to be held against a beam on the underside of the trailer, the plate having openings through which the ends of the rods project; means to hold the plate on the rods against the underside of the beam; the plate being dimensioned so that the rods extend above the opposite sides of the beam and alongside the flanges on the beam; means to overlie the flanges, said means being secured to ends of the rods above the plate and means on the ends of the rods clamping the overlying means against the flanges on opposite sides of the beam and the plate to holD the flanges against upward, lateral or downward movements relatively to the beam.
Claim 3
Dependent Claim
27 words
The mechanism of claim 1, wherein the base member has an upstanding flange, and yokes straddle the flange and are secured to the flange and the rods.
Claim 4
Dependent Claim
68 words
In the tiedown of claim 1: each means overlying the flanged beam comprising a plate having an opening by which it is fitted over the rod, and a length such that it can extend over the flange on one side of the rod and against the plate on the other, and a nut threaded onto the rod to force the overlying means against the flange and the plate.
Claim 5
Dependent Claim
78 words
In the tiedown of claim 1: the base member having two oppositely disposed walls, a bolt extending across from wall to wall; a strap secured to the bolt, to be extended over the trailer and have its opposite end secured on the opposite side of the trailer, means to releasably hold the bolt against turning, so that when the bolt has been turned to position to tighten the strap, the bolt may be releasably secured in such position.
Claim 6
Dependent Claim
