Post couplers
A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.
1. A post coupler for coupling separate post components together to form a post longer than the length of a post component, said post components comprising post flanges formed at an angle with respect to each other,
said coupler comprising:
post coupler flanges disposed at an angle with respect to each other;
reverse bend flanges extending from, along, parallel to and facing respective post coupler flanges; and
post stop elements extending outwardly from said post coupler flanges and on the same sides thereof facing respective reverse bend flanges, the post stop elements preventing insertion of a post component beyond post stop elements.
2. The post coupler as in claim 1 wherein said reverse bend flanges extend along inside surfaces of said post coupler flanges.
3. The post coupler as in claim 1 wherein said post stop elements comprise tabs extending from said post coupler flanges, said tabs having free ends and side edges separated from said post coupler flanges.
4. The post coupler as in claim 1 wherein said post stop elements comprise a single integral projection formed in and extending laterally along and from said post coupler flanges.
5. The post coupler as in claim 4 wherein said post coupler flanges intersect at said angle and wherein said post stop element extends from each post coupler flange around the intersection of said post coupler flange.
6. The post coupler as in claim 1 wherein said reverse bend flanges extend along outside surfaces of said post coupler flanges.
7. The post coupler as in claim 6 wherein said post stop elements comprise tabs extending from said post coupler flanges, said tabs having ends and side edges separated from said post coupler flanges.
8. The post coupler as in claim 6 wherein said post stop elements comprise integral projections formed in and extending laterally along and from said post coupler flanges.
9. A shelving unit, comprising:
a first post having a first post end;
a second post having a second post end;
a post coupler having first and second post coupler ends, comprising:
post coupler flanges disposed at an angle with respect to each other;
reverse bend flanges extending from, along, parallel to and facing respective post coupler flanges; and
post stop elements extending outwardly from the post coupler flanges and on the same sides thereof facing respective reverse bend flanges,
wherein the first post end being inserted into the first post coupler end and contacting the post stop elements and the second post end being inserted into the second post coupler end and contacting the post stop elements.
10. A shelving unit, comprising:
first and second posts, the first post having a first post end, the second post having a second post end, each post comprising:
post flanges disposed at an angle with respect to each other; and
reverse bend post flanges extending from, along, parallel to, and facing respective post flanges to form a gap between the post flanges and the reverse bend post flanges; and
a hidden post coupler having first and second hidden post coupler ends, the hidden post coupler comprising:
hidden post coupler flanges disposed at an angle with respect to each other; and
a post stop extending in a direction away from the respective hidden post coupler flanges,
wherein the first post end being inserted into the first hidden post coupler end and contacting the post stop and the second post end being inserted into the second post coupler end and contacting the post stop.
11. The shelving unit as in claim 10 wherein each said post stop comprises a tab having a free end spaced from a respective hidden post coupler flange.
12. The shelving unit as in claim 11 wherein each said tab comprises free edges spaced from a respective hidden post coupler flange.
13. The shelving unit as in claim 10 , wherein each post flange having a first length and each reverse bend post flange having a second length which is nearly as long as the first length such that hidden post couple is essentially hidden within the first and second posts.
