Break-away conncetor for sign post

Claim 2

A break-away connector for connecting to an in-ground post and na above-ground post of a highway sign, comprising: two elongated channels of generally U-shaped construction in cross-sectional view; and a stud having a tubular wall of a selected thickness with an outside surface sized to abut the inside surfaces of the channels with a central portion of the stud having a tubular wall thickness less than the selected thickness to provide an area of structural weakness for allowing the stud to fracture omnidirectionally, the stud welded at an upper portion to one channel and at a lower portion to the other channel to form an integral connector for wedging attachment to an in-groundpost and an above-ground post of a highway sign with bolts extending through spaced-apart bores in each of the channels with the central portion between the two channels, whereby the connector, being bolted to the in-ground post and the above-ground post of the highway sign, severs at the central portion upon impact of the highway sign by a motor vehicle regardless of the direction from which the impact is applied.

Claim 3

The break-away connector as recited in claim 1, wherein the wall thickness less than the selected thickness is defined by groove in the stud.

Claim 4

The break-away connector as recited in claim 1, further comprising at least one bore extending through the tubular wall and centered on the central portion.

Claim 5

The break-away connector as recited in claim 1, wherein the stud has two aligned radial bores through the tubular wall, each of the bores positioned next to a distal edge of a respective side wall of the channels.

Claim 6

The break-away connector as recited in claim 4, wherein the wall thickness less than the selected thickness is defined by a groove in the stud.

Claim 7

The break-away connector as recited in claim 5, wherein the bores are centered on the groove.

Claim 8

The break-away connector as recited in claim 1, wherein the stud is welded to the channels.

Claim 9

The break-away connector as recited in claim 1, wherein the stud is cylindrical.

Claim 10

The break-away connector as recited in claim 1, wherein the elongated channels having a flat web from which two side walls divergently extend outwardly with spaced-apart distal ends; and further comprising: a groove in the central portion that defines the wall thickness less than the selected thickness; and a pair of aligned radial bores centered on the groove, the stud positioned on the channels with the bores next to a respective side wall of the channels.

Claim 11

A highway sign post having a break-away connector, for supporting a highway sign and severing upon impact by a motor vehicle, comprising: two elongated channels that each define an interior receiving space, the channels of generally U-shaped construction in cross-sectional view; a stud having a selected wall thickness and a central portion defining a wall thickness less than the selected wall thickness to provide an area of structural weakness for severing omnidirectionally, the stud rigidly welded in an upper portion and a lower portion to the channels which are aligned in mutually spaced relation with the central portion located between the channels; an in-ground post of generally U-shaped construction in cross-sectional view connected to one of the channels with a pair of bolts extending through bores in the channel which is wedgingly received by the post; and an above-ground post of generally U-shaped construction in cross-sectional view connected to the other of the channels with a pair of bolts extending through bores in channel which is wedgingly received by the post, whereby a force of a sudden impact by a motor vehicle to the above-ground post, being transferred to the central portion, shears the stud.

Claim 12

A highway sign post having a break-away connector, for supporting a highway sign and severing upon impact by a motor vehicle, comprising: two elongated channels that each define an interior receiving space, the channels of generally U-shaped construction in cross-sectional view; a stud having a selected wall thickness and a central portion defining a wall thickness less than the selected wall thickness to provide an area of structural weakness for severing omnidirectionally, the stud rigidly welded in an upper portion and a lower portion to the channels which are aligned in mutually spaced relation with the central portion located between the channels; an in-ground post of generally U-shaped construction in cross-sectional view connected to one of the channels with a pair of bolts extending through bores in the channel which is wedgingly received by the post; and an above-ground post of generally U-shaped construction in cross-sectional view connected to the other of the channels with a pair of bolts extending through bores in channel which is wedgingly received by the post, whereby a force of a sudden impact by a motor vehicle to the above-ground post, being transferred to the central portion, shears the stud.

Claim 13

The highway sign post as recited in claim 10, wherein the wall thickness less than the selected thickness is defined by a groove in the stud.

Claim 14

The highway sign post as recited in claim 11, further comprising at least one bore extending through the tubular wall and centered on the groove.

Claim 15

The highway sign post as recited in claim 11, wherein the stud has two aligned radial bores through the tubular wall, each of the bores positioned next to a distal edge of a respective side wall of the channels.

Claim 16

The highway sign post as recited in claim 13, wherein the bores are centered on the groove.

Claim 17

The highway sign post as recited in claim 10, wherein the stud is welded to the channels.

Claim 18

The highway sign post as recited in claim 10, wherein the stud is cylindrical.

Claim 19

The highway sign post as recited in claim 10, wherein the elongated channels are of generally U-shaped construction having a flat web from which two side walls divergently extend outwardly with spaced-apart distal ends.

Claim 20

The highway sign post as recited in claim 13, wherein each of the bores are positioned next to a respective one of the distal ends of the side walls of the channel.

Claim 23

The method as recited in claim 19, further comprising the steps: boring at least one hole in the stud centered on the groove; and positioning the stud with the hole between adjacent edges of the spaced-apart channels.
