A cargo tiedown anchor for mounting on a vehicle or wall comprises a raised central circular portion on the front surface of a back plate and is rotatably positionable in an opening in a wall of a structural member on a vehicle. A U-shaped clip has a pair of legs and a tiedown ring is loosely retained between the legs of the clip. The legs are inserted in slots in the raised central circular portion of the back plate such that the ends of the legs protrude beyond the rear surface of the back plate. The clip is attached to the back plate behind the wall with the opening by welding around the outlines of the protruding leg ends.

The present invention relates to a tiedown anchor in which a U-shaped clip which retains a tiedown ring is attached to a wall surface for securing cargo lines on vehicles, more particularly, to the structure for securing the U-clip to the surface of a vehicle.
In the shipment of cargo, particularly by motor vehicle, it has been the practice to secure the cargo in position by means of straps or cargo lines which are attached to anchors which have been fixed upon walls, truck sides, the side beams of trailers and similar places. The anchor generally comprises a tiedown ring which is attached by a clip to a wall of the vehicle such that the ring has at least limited pivotable movement around the attaching member. One particular structure involves a U-shaped clip which retains a tiedown ring and the ends or legs of the clip are then welded directly to the side walls of the vehicle body or frame. The strength of such a tiedown anchor is entirely dependent on the weld of the clip to the wall surface. Further, the tiedown ring which is a component of this anchor is pivotable in a fixed vertical plane. Since in many instances the cargo lines secured to the anchor are positioned not in a vertical plane but at an angle to the vertical it is readily apparent that a side or twisting force is exerted against the tiedown anchor when the line has been secured in position. This additional side tension applied to the tiedown ring and clip detracts from the safety and operating life of the tiedown anchor.
It is therefore the object of the present invention to provide a novel and improved cargo tiedown anchor for vehicles.
Other objects and advantages of the present invention will be apparent upon reference to the accompanying description when taken in conjunction with the following drawings, which are exemplary, wherein;
FIG. 1 is a perspective view of the components of the cargo tiedown anchor according to the present invention before assembly;
FIG. 2 is a front elevational view of the tiedown anchor of the present invention mounted in a side rail member of a trailer vehicle;
Proceeding next to the drawings wherein like reference symbols indicate the same parts throughout the various views, a specific embodiment and modifications of the present invention will be described in detail.
A cargo tiedown anchor according to the present invention is indicated generally at 10 in FIG. 2 and is mounted in an opening in a structural member 11. The several components of the tiedown anchor are illustrated in FIG. 1 and will be presently described in detail.
The structural member 11 is a typical 8 inch structural channel which is a common side rail member for a trailer. However, the structural member 11 may be any size channel, beam or other structural component.
