Abstract

Abstract Disclosed is a tiedown device for use in tying a load in place on a truck or railroad car. The tiedown device has an elongated plate with a series of indentations in each side edge, a lug body slidably mounted on the plate topside and having a shoulder portion and a pair of arms downwardly and inwardly depending from the shoulder portion and terminating in nose portions adapted to contact the underside of the plate upon upward displacement of the lug body, an upwardly extending tooth on at least one of the arms adapted to extend into an indentation in the plate when the nose portions contact the underside of the plate, and means on the lug body for attaching a tiedown strap or line.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 173 words
A tiedown device comprising: an elongated rigid fixedly secured plate, having a series of indentations in each side edge, horizontally mounted on a vertical web; a lug body slidably mounted on the plate topside and having a shoulder portion and a pair of arcuate arms downwardly and inwardly depending from the shoulder portion and terminating in rounded nose portions adapted to contact the underside of the plate close to the vertical web upon upward displacement of the lug with the remaining portion of the arms spaced away from the plate edges and underside of the plate; an upwardly extending tooth on each of the arms adapted to extend into an indentation in the plate edge when the nose portions contact the underside of the plate; the space between the shoulder and tooth being greater than the thickness of the plate, and the thickness of the arms is greater than the thickness of the tooth and the thickness of the indentations; and means on the lug body for attaching a tiedown strap or line.
Claim 2
Dependent Claim 173 words
A tiedown device comprising: an elongated rigid fixedly secured plate, having a series of indentations in each side edge, horizontally mounted on a vertical web; a lug body slidably mounted on the plate topside and having a shoulder portion and a pair of arcuate arms downwardly and inwardly depending from the shoulder portion and terminating in rounded nose portions adapted to contact the underside of the plate close to the vertical web upon upward displacement of the lug with the remaining portion of the arms spaced away from the plate edges and underside of the plate; an upwardly extending tooth on each of the arms adapted to extend into an indentation in the plate edge when the nose portions contact the underside of the plate; the space between the shoulder and tooth being greater than the thickness of the plate, and the thickness of the arms is greater than the thickness of the tooth and the thickness of the indentations; and means on the lug body for attaching a tiedown strap or line.
Claim 3
Dependent Claim 64 words
A tiedown device according to claim 1 having locking means to hold the lug body in temporarily fixed position with the tooth engaged in an indentation in the plate, said locking means comprising a flat plate element rotatably mounted on the lug body by a pin horizontally positioned and perpendicular to the lug body to keep the shoulder displaced upwardly above the plate topside.
Claim 4
Dependent Claim 27 words
A tiedown device according to claim 2 in which the locking means element has a flat surface which contacts the plate topside surface when in locking position.
Claim 5
Dependent Claim 194 words
A tiedown device comprising: an elongated rigid fixedly secured plate, having a series of indentations in each side edge, horizontally mounted on a vertical web; a lug body slidably mounted on the plate topside and having a shoulder portion and a pair of arcuate arms downwardly and inwardly depending from the shoulder portion and terminating in rounded nose portions adapted to contact the underside of the plate close to the vertical web upon upward displacement of the lug with the remaining portion of the arms spaced away from the plate edges and underside of the plate; an upwardly extending tooth on each of the arms adapted to extend into an indentation in the plate when the nose portions contact the underside of the plate; the space between the shoulder and tooth being greater than the thickness of the plate, and the thickness of the arms is greater than the thickness of the tooth and the thickness of the indentations; each tooth having opposing flat parallel sides and a front face which joins the arm below the top of the nose portion; and means on the lug body for attaching a tiedown strap or line.
Claim 6
Dependent Claim 194 words
A tiedown device comprising: an elongated rigid fixedly secured plate, having a series of indentations in each side edge, horizontally mounted on a vertical web; a lug body slidably mounted on the plate topside and having a shoulder portion and a pair of arcuate arms downwardly and inwardly depending from the shoulder portion and terminating in rounded nose portions adapted to contact the underside of the plate close to the vertical web upon upward displacement of the lug with the remaining portion of the arms spaced away from the plate edges and underside of the plate; an upwardly extending tooth on each of the arms adapted to extend into an indentation in the plate when the nose portions contact the underside of the plate; the space between the shoulder and tooth being greater than the thickness of the plate, and the thickness of the arms is greater than the thickness of the tooth and the thickness of the indentations; each tooth having opposing flat parallel sides and a front face which joins the arm below the top of the nose portion; and means on the lug body for attaching a tiedown strap or line.
Claim 7
Dependent Claim 20 words
A tiedown device according to claim 4 in which each tooth is centrally located between the width of the arm.
Claim 8
Dependent Claim 24 words
A tiedown device according to claim 4 in which the sides of the tooth intersect the inner side of the arm in arcuate lines.
